Description

IX. INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present disclosure relates generally to wireless communication systems. More specifically, the embodiments disclosed herein relate to carrier allocation and management in a multi-carrier communication system. [Prior Art] A communication system has been developed to allow information signals from an origin station to be transmitted to physically different target stations. When transmitting an information signal from the originating station via the communication channel, the information signal is first converted into a form suitable for efficient transmission via the communication channel. The conversion or modulation of the information signal involves changing the parameters of the carrier in accordance with the information signal in such a manner that the spectrum of the resulting modulated carrier is limited to the bandwidth of the communication channel. At the target station, the original information signal is copied from the modulated carrier received via the communication channel. This duplication is usually achieved by using the reverse process of the modulation process employed by the origin station. Modulation also facilitates multi-directional proximity, for example, simultaneous transmission and/or reception of several signals via a common communication channel. For example, a multi-directional proximity communication system may include a plurality of remote subscriber units (or access terminals) that require intermittent service to a common communication channel rather than continuous access. Multi-directional proximity technology may include coded multi-directional proximity (CDMA), time-of-flight multi-directional proximity (TDMA), frequency-multidirectional proximity (FDMA), quadrature-frequency multi-directional proximity (〇FDMA), and other multi-directional proximity technologies. . The multi-directional proximity communication system can be wireless and/or wired, and can carry the language 曰 data# and the like. The communication system can be designed to implement - or multiple standards 11503 丨.doc 1336195. As the demand for multimedia services and south rate data has grown rapidly, multi-carrier modulation in wireless communication systems has been proposed. There is a challenge to provide an efficient and robust multi-carrier communication system. SUMMARY OF THE INVENTION Embodiments disclosed herein relate to carrier allocation and management in a multi-carrier communication system. In some embodiments, the number of carriers assigned to an access terminal on a forward link can be determined by an access network and assigned to the access terminal on a reverse link. The number of carriers of the machine may be based on a collaborative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be, for example, with respect to scheduling information received from the access terminal by the access network. To judge. [Embodiment] The embodiments disclosed herein relate to a method and apparatus for carrier allocation and management in a communication system.

A cell may refer to a coverage area served by an AP. The cell may further include or a sector. For the sake of brevity and clarity, the term "sector" may be used herein to refer to a segment of a cell or cell served by an AP.

The ANC may include and/or implement functions such as a Base Station Controller (BSC) found in a 2nd, 3rd or 4th generation wireless network. The ANC and one or more APs may form part of an access network (AN). An access terminal (AT) as described herein may refer to various types of devices including, but not limited to, a wireless telephone, a cellular telephone, a laptop, a multimedia wireless device, a wireless communication personal computer (PC) card, an individual. Digital Assistant (PDA), external or internal data machine, and more.

The AT can have various names such as access units, access nodes, subscriber units, mobile stations, mobile devices, mobile units, mobile phones, mobiles, remote stations, remote terminals, remote units, user devices, User equipment, handheld devices, and more. Different Ατ can be incorporated into a system. The AT can be mobile or fixed and can be dispersed throughout the communication system. The AT can communicate with one or more APs on the forward link and/or the reverse link at a given time. The forward link (or downlink) refers to the transmission from Ap to Octopus. Reverse link (or uplink) refers to the transmission from AT to Ap. 1 illustrates a wireless communication system 100 that is configured to support a number of users, in which various disclosed embodiments and aspects can be implemented as described further below. By way of example, system 100 provides communication for a number of cells 1 (including cells 102A-102G), each of which is served by a respective Ap 104, such as AP 104A-104G. Each cell can be further divided into one or more sectors. The various Ατ 1〇6 including AT 106A-106K are dispersed throughout the 115031.doc system. For example, depending on whether Ατ县不士 L ^ 仇 A1 is valid and whether it is in soft delivery, each AT 106 can be programmed to make π*·»·ι J in , , . The time is communicated with one or more APs 〇4 on the forward link and/or the reverse link.

Reverse link communication is not explicitly shown. The ΑΡ 104 may each be equipped with one or more receiving antennas and one or more transmission antennas. There may be any combination of transmit and receive antennas at ΑΡ 104. Similarly, each AT 106 can be equipped with one or more receive and transmit antennas or a combination thereof. System 100 can be configured to support one or more standards, such as H95,

For example, in one embodiment, System 1 may be a high rate as specified in the "cdma2000 High Rate Packet Data Air Interface Specification" in 3GPP2 C.S0024-B, 1st edition, May 2006. Packet Data (HRPD) system (also known as "ixEV-DO" or "IS-856" type system.) In addition, 'various algorithms and methods can be used to schedule transmissions and facilitate communication in system 100. Details of such algorithms and methods for use in a 1 xEV-DO system are further described below. Figure 2 illustrates an embodiment of AN 204 and AT 206 in a communication system. By way of example, AT 206 can be, for example, The reverse 115031.doc link including the reverse traffic channel 208 is in wireless communication with the AN 204. The reverse traffic channel 2〇8 is the portion of the reverse channel that carries information from the AT 206 to the AN 204. In addition to the traffic channel 208, the reverse channel can also include other channels. In addition, the AT 206 can wirelessly communicate with the AN 204 on the link before including a plurality of channels (eg, navigation, traffic, and other channels). Unclear exhibition In Figure 2, the functionality performed by AT 206 can be organized as a layer stack. Figure 3 illustrates a layer stack on AT 306. Between these layers is a Media Access Control (MAC) layer 308. Higher layer 310 Located above the MAC layer 308. The MAC layer 308 provides certain services to the higher layer 310, including services related to the operation of the reverse traffic channel 202. The MAC layer 308 includes a reverse traffic channel (RTC) MAC protocol 314. An embodiment. The RTC MAC protocol 3 14 provides a procedure followed by the AT 306 to transmit the reverse traffic channel 208 and followed by the AN 204 to receive the reverse traffic channel 208. The physical layer 312 is located below the MAC layer 308. The MAC layer 308 Some services are requested from the entity layer 312. These services are related to the physical transport of the packets of the AN 204. Figure 4 illustrates an exemplary interaction between the higher layer 410, the MAC layer 408, and the physical layer 412 on the AT 406. As shown, the MAC layer 408 operates one or more streams 416 from a higher layer 41. Stream 416 is a stream of data from a user source having a predetermined transmission requirement (example > associated with a particular application) For example, 'stream 416 corresponds to a specific application, such as voice IP (V 〇lP), video telephony, file transfer protocol (FTP), game 'etc. 0 n5031.doc -10· 1336195 Transfer the data from stream 416 on AT 406 to AN 2〇4 in packet open > . According to the RTC MAC protocol 414, the MAC layer determines a stream set 418 for each packet. Sometimes, multiple streams 416 on the AT 406 have to be simultaneously

Information transmitted. The packet may include data from more than one stream 416. g, and sometimes, there may be one or more streams 416 on the AT 406 that have data to be transmitted but are not included in the packet. The set of packets 418 indicates the stream 416 on the AT 406 to be included in the packet. An exemplary method for determining a stream set 418 of packets is described below. The MAC layer 408 also determines the payload size of each packet 42 〇. The payload size 420 of the packet indicates how much of the data from the stream set 418 is included in the packet. The MAC layer 408 also determines the power level 422 of the packet. In some embodiments, the power level of the packet is determined 422 relative to the power level of the reverse pilot channel. For each packet transmitted to the AN 204, the MAC layer 4〇8 communicates the stream set 418 to be included in the packet, the payload size 42 of the packet, and the power level 422 of the packet to the physical layer 412. The physical layer 412 then implements the transmission of the packet to the AN 2〇4 based on the information provided by the Mac layer 408. 5A and 5B illustrate a packet 524 transmitted from the AT 506 to the AN 5〇4. Packet 524 can be transmitted in a number of possible transmission modes (TM). For example, in some implementations, there are two possible Chuanlong: high-capacity transmission mode and low-latency transmission mode 15A description--transmission to the high-capacity packet 524a of the 504 (ie, in high-capacity mode) Transfer spoon 524a). Figure 5B illustrates a low latency block of 115-5.doc • 11· 1336195 524b (i.e., packet 52 transmitted in low latency mode can be transmitted using low latency (LoLat) transmission. Mode to transmit data from a delay-sensitive stream (LoLat stream). High-capacity (HiCap) transmission mode can be used to transmit data from a delayed allowed stream (HiCap stream). Low latency packet 524b and high-capacity packet of the same packet size 52牦 is transmitted at a higher power level 422. Therefore, the low latency packet 52 is likely to arrive at AN 5〇4 faster than the high-capacity packet 524a. However, the low latency packet 524b and high capacity The packet 524a will result in a greater load on the system 1 . Figure 6 illustrates different types of streams 616 that may be present on the AT 6〇 6. In some embodiments, each stream 616 and one on the AT 606 The particular transmission mode is associated. Where the possible transmission mode is a high capacity transmission mode and a low latency transmission mode, the AT 606 can include one or more high capacity streams 616 & and/or one or more low latency streams 616b. Preferably The high-capacity packet 524a transmits the high-capacity stream 616a. Preferably, the low-latency packet 620b transmits the low latency stream 616b. Figure 7 illustrates an example of a stream set 718 for the high-capacity packet 724a. In some implementations In the example, the packet 72 is transmitted in the high capacity mode only when all of the streams 716 having the data to be transmitted are the high capacity stream 716a. Therefore, in the respective embodiments, the stream set 718 in the high capacity packet 724a. Include only the high-capacity stream 716a, or, as with AT 6〇6, the low latency stream 61讣 may be included in the high-capacity packet 724a. One exemplary reason for doing so is that sufficient flow is not achieved at the low latency stream 616b. For example, it may be detected that the queue of low latency stream 616b is accumulating β. The stream can be changed to 115031.doc -12-

S, the amount is modified by the capacity mode to increase latency. FIG. 8 illustrates an exemplary stream set 818 for the low latency packet 824b. In some embodiments, if there is a to-be-transmitted At least the low latency stream 816b of the data transmits the packet 824b in a low latency mode. The low latency packet "stream set 818 in 4b includes a per-low latency stream 816b having a body to be transmitted. The or multiple capacity stream 8163 having the material to be transmitted may also be included in the stream set 818. One or more high-capacity streams 816a of the eight data to be transmitted may not be included in the stream set 818. 'Consolidate parallel low latency streams and high-capacity streams into physical layer packets in each reverse link carrier Merging occurs when AT 906 contains multiple different termination target streams. Since each entity packet can have a termination target, the rules can be used to determine when streams can be merged into the same packet. Used to parallel low latency flows and high The rules for combining the capacity streams into the packets depend on the flow priority and the sector load. Figure 9 illustrates information that can be maintained at Ατ 9〇6 to determine whether the high-capacity stream 916& is included in the stream set 818 of the low latency packet 824b. Each of the high-capacity streams 916a on Ατ 9〇6 has a certain amount of data 926 that can be used for transmission. Also, a merge threshold 928 can be defined for each high-capacity stream 916a on the AT 906. The merge threshold can be defined for at 906 as a whole. Finally, the combination of high-capacity flows can occur when the estimate of the load level of the sector is less than the threshold. (How to determine the load level of the sector is discussed below. Estimate.) That is, when the sector is loaded slightly enough, the combined efficiency loss 115031.doc 13 1336195 flows 916a. Conversely 'if the merge threshold 92 8 for the high-capacity stream 916a is set to Very small value, this means that the high-capacity stream 9丨6& is almost always included in the low latency packet 824b. Therefore, the high-capacity streams 916a can experience very small transmission delays. However, such high-capacity streams 916& uses more sector resources to transmit its data. In some embodiments, the merge threshold 928 for certain high-capacity streams 916a on AT 9〇6 can be set to a very large value. The merge threshold 928 for some other high-capacity streams 916 & τ on the τ 906 is set to a very small merge threshold 928. This design is advantageous because certain types of high-capacity streams 916a may Have strict qoS requirements, while other types may not An example of a stream 916 having strict QoS requirements and capable of being transmitted in a high capacity mode is instant video. Instant video has a high frequency bandwidth requirement, which makes transmission efficiency in a low latency mode low. However, no random transmission is required for instant video. An example of a flow 916 that delays transmission without a strict q〇s delay requirement and can be transmitted in a high-capacity mode is best effort (best eff〇rth^ 916. Setting the power level of a packet in a given reverse link carrier) FIG. 10 illustrates one AN 1004 and a plurality of ATs 1006 within sector 1032. Sector 1032 is a geographic area that can receive signals from AN 1004 by AT 1006 and vice versa. A feature of some wireless communication systems, such as CDM systems, is that transmissions interfere with one another. Therefore, to ensure that there is not much interference between AT 1〇〇6 in the same sector 1〇32, there is a limited amount of power received by AN 1004 that can be used by the entire AT 1006. To ensure that Ατ 1〇〇6 remains within this limit, a 115031.doc •15-^S* 1336195 'power 1034 can be used for each AT 1006 in sector 1032 for use in reverse traffic channel 20 Transmission on 8 Each AT 1006 sets its power level 422 ' of the packet 524 transmitted on the reverse traffic channel 208 so as not to exceed its total available power 1034 β

The power level 1034 assigned to ΑΤ 1006 may not be exactly equal to the power level 422 used by the AT 1006 to transmit the packet 524 on the reverse traffic channel. For example, in some embodiments, when determining the power level 422 of the packet 524, there is a set of discrete power levels selected by AT 1〇〇6. The total available power 1034 with #八八丁1006 may not be exactly equal to any discrete power level. The total available power 1034 that is not used at any given time is allowed to accumulate so that it can be used for subsequent times. Thus, the total available power for the AT 1006 in the embodiments is approximately 等于34 (approximately) equal to the current power allocation 1034& plus at least some portion of the accumulated power allocation 1034b. The AT 1006 determines the power level 422 of the packet 524 such that it does not exceed the total available power 1034 for AT 1 〇 〇 6. • The total available power 1034 for AT 1006 may not always be equal to the current power allocation l〇34a of AT 1006 plus the accumulated power allocation 1034b of AT 1006. In some embodiments, the total available power 1034 of AT 1006 may be limited to peak allocation 1034c. The peak allocation 1034c for AT 1006 can be equal to the current power allocation 1034& for AT 1006 multiplied by a certain limiting factor. For example, if the limiting factor is 2' then the peak allocation of AT 1006 is 1034 <^ equal to twice its current power allocation 1034a. In some embodiments the 'limit factor is a function of the current power allocation 1034& for AT 1006. 115031.doc • 16- 1336195 Provides peak distribution for AT i〇34c can limit the transmission of AT 1〇〇6. How to "bursty" For example, a system that may occur, AT 1〇〇6 does not have data to be transmitted during a certain period of time. During this time period, power can continue to be allocated to AT 1〇06. Since there is no data to be transmitted, the allocated power accumulates. At some point, the AT 1006 can suddenly have a relatively large amount of data to be transmitted. At this point, the accumulated power distribution 丨〇 34b can be relatively large. If the AT 1006 is allowed to use the entire accumulated power allocation 1〇3413, the transmission power 422 of the AT 1〇〇6 may experience a sudden rapid increase. However, if the transmission power 422 of the AT 1006 increases too quickly, this can affect the stability of the system. Thus, in the case of such, a peak allocation 1034c may be provided to AT 1 006 to limit the total available power 〇 34 of Ατ 1〇〇6. It should be noted that the accumulated power allocation 10341) is still available, but its use is extended to more packets when the peak allocation l〇34c is limited. Aligning Data Flows in a Single Reverse Link Carrier Figure 11 illustrates an exemplary mechanism that can be used to determine the total available power of the AT 206, 1〇34. This mechanism involves the use of virtual "buckets" 1136. This RLMAc bucket is used for each data stream to organize data streams and control stream access. First, the data generated by the application stream is adjusted in the data field. The average and peak resources used by the stream are less than or equal to the limit value. The collated data stream is operated using the following method. The new current power allocation 1034a is added to the bucket 1136 at periodic intervals. The packet transmitted by the AT 2〇6 μ The power level 422 of # also exits the bucket 1136 at periodic intervals. The current power allocation 1034a exceeds the power level 422 of the packet by the accumulated power allocation 1034b. The accumulated power allocation 1〇34b is still in the barrel magazine until It uses 115031.doc 17 1336195. The total available power 1034 minus the current power allocation 1034a is the total potential extraction from bucket 1136. AT 1〇〇6 ensures that the power level 422 of the packet 524 it transmits does not exceed The total available power of AT 1006 is 1034. As indicated previously, in some cases, the total available power 1〇34 is less than the current power allocation l〇34a and the accumulated power distribution 1〇3 Park For example, the total available power 1034 can be limited to the peak power allocation 1 〇 34c. The accumulated power allocation 103 4b can be limited to the saturation level 1135. In some embodiments, the saturation level 1135 is allowed Ατ 1 〇〇6 utilizes its peak power distribution as a function of the amount of time 1010. The bucket 1136 above the saturation level 1135 may indicate over-allocation due to one of three reasons: i) pA headroom or Data limit; ii) T2PInfl〇w 1035 decays to the minimum value of AN 1004 control; or iii) T2Pflow 1035 begins to increase when the stream is no longer over-allocated. T2PInfl〇w 1〇35 is defined as the current assignment in the network The resource level of the current flow. Therefore, Ding 2?11^1 comment 1035 = new resource inflow (long-term T2P resource based on the flow priority assigned by AN 1 004). With each reverse link carrier Flow access control for allocating resources between multiple streams associated with AT 1206

Figure 12 illustrates an embodiment in which at least some of the ATs 1206 within the sector 1232 include a plurality of streams 1216. The resources between the multiple streams associated with the AT 1206 are allocated in a manner that maintains quality assurance (q0s). In this embodiment, an independent amount of available power can be determined for each stream 1216 on the AT 1206. The available power for the stream 1216 on the AT 12〇6 can be determined according to the method previously described in connection with Figures 10-11. 1238 » Each stream will be used to store unused T2P 115031.doc < S :, 1336195 buckets up to a certain maximum level. When the stream data arrives, the bucket-resource is used to allocate the packet with a maximum bucket decimation rate based on the peak-to-average access control. In this way, the average resource usage is limited to T2PInfl〇w 1G35, but the local burst allocation can be used to benefit from the data source. The peak-to-average control (called BucketFactor) limits the power received by AN 1004. How do you like each other? For example, the total available power 1238 for stream 1216 can include a current power allocation 1238a for stream 1216 plus at least some portion of the accumulated power # allocation 12 times for stream 1216. In addition, the total available power 1238 for stream 1216 can be limited to a peak allocation i238c for stream 1216. A separate bucket mechanism, such as the one shown in Figure u (which utilizes the parameters BucketLevel and T2PInfl〇w 1235 described below), can be maintained for each class 1216 to determine the total available power 丨 238 for each of the machines 1216. The total available power 1234 for Ατ 1206 can be determined by employing the sum of the total available power 1238 for the different streams 1216 on Ατ 1 . • The following k provides a mathematical description of the various equations and algorithms that can be used in the determination of the total available power 12 3 8 of stream 1216 on AT 12 0 6 . In the equations described below, the total available power 1238 for each stream z Α on Ατ 12〇6 is determined once in each subframe. (In some embodiments, a sub-frame is equal to four time slots, and a time slot is equal to 5/3 ms.) The total available power I238 for the stream is referred to in the equation as (4).

The AN 1304 for a given reverse link carrier acquires the current power allocation 1338a for the 13031.doc •21 · 1336195 stream 1316 on the AT 1306.

In some implementations, obtaining the current power allocation 1338a can be a two-step process. Stream resources may be allocated in a decentralized manner by each AT 13〇6 (autonomous mode) or using an authorization 1374 from a central controller or scheduler 1340 located in the AN 1304. Figure 13 illustrates a manner in which Ατ 13〇6 can be used to obtain the current power allocation 1338& for stream 13 16 in the form of centralized control of network resource allocation by Π04. As shown, 1306 can receive an authorization message 1342 from scheduler 134 executing on AN 1304. The authorization message 1342 may include a power allocation grant 1374 for some or all of the "il 1316 on Ατ 13〇6. The authorization 1374 may be a resource allocation (rather than every packet allocation), which allows AN 13〇 4 Provide resource allocation updates and changes. It also allows for detailed signal transmission within the band of QOS information. For each current power allocation grant 1374 received, AT 13〇6 sets the current power allocation n38a for the corresponding stream 13 16 to be equal to the current power allocation grant 1374. Authorize 1374 to allocate and freeze power allocation for a duration of one

time interval. Thus 'AN 1304 controls flow resource allocation during this time interval. As described above, the streaming resources may be allocated in a decentralized manner by each AT丨3〇6 (autonomous mode) or using an authorization 1374 from a central controller or scheduler 1340 located in AN 13 04. Therefore, the first step involves determining whether a current power allocation grant 1374 for stream 1316 has been received from AN 1304. If not, then AT 1306 autonomously determines the current power allocation 1338a for stream 12 16 . In other words, AT 1306 determines the current power allocation 1338a for stream 1216 without being interfered with by scheduler 1340. This can be called -22- 115031.doc 1336195 autonomous mode. The following discussion is directed to an exemplary method of having AT 1306 autonomously determine a current power allocation 1338 & for one or more streams 13 16 at at 1306. Autonomously determining the current power allocation 1238a for one or more of the reverse link carriers 1 Figure 16 illustrates the reverse activity bit (RAB) 1444 transmitted from the AN 1404 to the AT 1406 within the sector 1432. The access node 14〇4 uses rab to notify the AT 1406 in its coverage area of the current traffic activity via the reverse link. Therefore, RAB 1444 is an overload indication. The AT incorporates this information when deciding whether to reduce its traffic rate due to the high traffic load on the reverse link or to increase its traffic rate due to the low traffic load on the reverse link. The RAB 1444 can be one of two values: a first value (e.g., +1) indicating that the sector 1432 is currently busy, or a second value (e.g., -1) indicating that the sector 1432 is currently idle. The RAB 1444 can be used to determine the current power allocation 1238a for the stream 1216 on the AT 1206, as explained below. It should be noted that whether it is a shared AT 1406 or an AT 1406, stream 1216 observes the same RAB 1444 in each sector » This can be a simplified design for scaling in multiple streams. Using the short and long RAB estimates for each reverse link carrier to determine the current power allocation from the primary location 1238a. Figure 15 illustrates that it can be maintained at AT 1506 to determine the current power allocation for one or more of the flows 1516 on the AT 1506. 1238a information. In the illustrated embodiment, each stream 1516 is associated with one of the RABs 1444, a fast " or "short" estimate. This quick estimate will be referred to herein as qrAB 1 546. An exemplary method for determining QRAB 1546, β per first 1516, is also associated with an estimate of the longer term load level of sector 1232, which is referred to herein as FRAB 1548 (hereinafter) -23-H5031.doc 1336195 (hereinafter) Its representative, according to the wave "rab 1444). FRAB is a measure of sector load similar to QRAB 1546 but has a longer time constant ^ Therefore, qRAB is relatively instantaneous, while FRAB 1548 gives longer-term sector load information. FRAB i is a real number somewhere between two possible values of RAB 1444, for example, + 1 and -1. However, other numbers can be used for the value of RAB 1444. The closer frab 1548 is to the value indicating the busy RAB 1444 of sector 1432, the more heavily sector 1432 is loaded. Conversely, the closer FRAB 1548 is to the value of RAB 1444 indicating that sector 1432 is idle, the less heavily sector 1432 is loaded. The following description determines one example of FRAB 1548. Each first-class 1516 is also associated with an upward ramp function (upward called (four) funCtlon) 1550 and a downward ramp function (d〇wnward funct10n) 1552. The up ramp function 1550 and down ramp function 1552 associated with a particular stream 1516 is a function of the current power allocation 1238a for stream 1516. The up ramp function 1550 associated with stream 1516 is used to determine the increase in current power allocation 1238& for stream 1516. Conversely, the downward ramp function 丨 552 associated with stream 1 51 6 is used to determine the reduction in current power allocation 1238 & for stream 1516. In some embodiments, both the up ramp function 15 50 and the down ramp function 1552 are dependent on the value of FRAB 1548 and the current power allocation i238a for stream 1516. Because the up ramp function 1550 and the down ramp function 1552 depend on the value of FRAB as a load dependent ramp function. Therefore, the frab allows unloaded II503I.doc -24-

< S 1336195 T2P slope dynamics decoupling from steady-state T2p dynamics of the load. When the sector is unloaded, a faster ramp is needed to quickly and smoothly fill the sector capacity. When the sector is loaded, a slower slope is needed to reduce the Rise_ 〇ver-Thermal (RoT) change. R 〇 T at a sector is determined as the ratio of the total received power to the thermal noise power. This number is measurable and self-correcting and provides an estimate of the interference observed by each AT 1506. In other methods, a fixed slope is used, resulting in a trade-off between these conflicting needs. ® defines an up ramp function 1550 and a down ramp function 1552 for each stream 15 16 in the network, and it can be downloaded from the AN 14〇4 of the AT 15〇6 that controls the stream. The up ramp function and the down ramp function have the current power allocation 1238a of the stream as its augument. The upward ramp function 155 有时 will sometimes be referred to herein as gu, and the downward ramp function 1552 will sometimes be referred to herein as gd. The ratio of gu/gd (also a function of current power allocation 1238a) is called demand. Or priority function. It can be confirmed that the reverse link MAC (RLMac) method converges to the current power allocation 1238& for each stream 1516, so that all flow demand function values are allocated in its flow, subject to the data and access terminal power availability. When the place is adopted, it is equal. By using this fact and judiciously designing the flow demand function, it is possible to have the same general mapping as the general mapping of resource allocations that can be achieved by a centralized scheduler. However, the demand function method transmits with minimal control signals and achieves this general scheduling capability in a decentralized manner. The up and down ramp functions allow fast traffic in the sector with a slight load to increase the pilot channel power (T2p), the sector to smooth the fit (filin& in), as the sector load increases Low skew ^ 15031 .doc -25· 1336195 Slope and T2P dynamics decoupling between load and unloaded sectors. Here, T2P is used as a sector resource. For a fixed termination target, T2P increases approximately linearly at the rate of streaming. Components for Determining QRAB 1646 and FRAB 1648 for Each Reverse Link Carrier in AT 1506 FIG. 16 is a block diagram illustrating exemplary functional components of AT 1606 that may be used to determine QRAB 1646 and FRAB 1648. As shown, the AT 1606 can include an RAB demodulation component 1654, a mapper 1656, first and second monopole IIR filters 1658, 1660, and a limiting device 1662. RAB 1644 is transmitted from AN 1604 to AT 1606 across communication channel 1664. The RAB demodulation component 1654 uses a standard technique known to those skilled in the art to demodulate the received signal. The RAB Demodulation Component 1654 outputs a Log Likelihood Ratio (LLR) 1666. Mapper 1656 takes LLR 1666 as an input and maps LLR 1666 to a value (e.g., +1 and -1) between the possible values of RAB 1644, which is an estimate of the transmitted RAB for the slot. The output of mapper 1656 is provided to a first monopolar HR filter 1658. The first IIR filter 1658 has a time constant ^. The output of the first HR filter 1658 is provided to a limiting device 1662. Restriction device 1662 converts the output of first IIR filter 1658 to one of two possible values corresponding to two possible values of mrab 1644. For example, if RAB 1644 is -1 or + 1 ', then limiting device 1662 converts the output of first IIR filter 1658 to -1 or +1. The output of the limiting device 1662 is QRAB 1646.

In one example, qRab can be updated once per slot. The output of mapper 1656 is also provided to a second with time constant ~ The output of the second IIR chopper 166 is frab 1648. The time constant 1 is longer than the time constant %. An exemplary value for the time constant ^ is 384 time slots. The output of the second IIR filter 1660 is provided to the limiting device. Thus, as described above, FRAB 1648 is the second value of one of the mRAB 1644 indicating that the sector 1432 is busy and the indicating sector 1432 of the RAB 1644 is idle. A real number somewhere in between. Figure 17 illustrates an exemplary method 17 for determining the current power allocation 1238a for stream 1216 on AT 12〇6. Step 17 of method 17 involves decision and The value of qRAB 1546 associated with stream 1216. In step (5), it is determined whether QRAB 1546 is equal to a busy value (ie, indicating that the sector M32 is currently busy) e gQRAB 1546 is equal to the busy value, then in step 1706 Decrease the current power allocation 1238a, ie, at the time The current power allocation 1238a for stream 1216 is less than the current power allocation 1238a for stream 1216 at time. The reduced magnitude value can be calculated using the downward ramp function 1 5 5 2 defined by stream 1216. If QRAB 1546 Equal to an idle value, the current power allocation 1238a is added in step 17〇8, that is, the current power allocation 丨 238 & for the rogue 216 during the current time interval is greater than the stream 12 during most recent time intervals.当前6 current power allocation 1238a.

In some embodiments, it is the ratio of the pilot sector FL pilot power to the pilot power of other sectors.

This allows for the persistence of the value of the current power allocation 1238a for the burst source, for which the duration should be longer than the typical interarrival time. In some embodiments A QRAB value of 1546 is estimated for each of the effective sets of ATs 1206. If the QRAB is busy for any sector in the active set of ATs, then the current power allocation 1238a is reduced. If the QRAB is idle for all sectors in the active set of ATs, then the current power allocation 1238a is incremented. In an alternate embodiment, another parameter QRABps may be defined. II503 丨.doc -29- 1336195 For QRABps, consider the measured pilot strength. (The pilot strength is a measure of the pilot power of the serving sector versus other sectors. In some embodiments, it is the ratio of the pilot sector FL pilot power to the pilot power of other sectors. Depending on the contribution of AT 1206 to reverse link interference in sectors in the active set of AT 1206, QRABps can be used to account for short-term sector loading. If the QRAB is busy for a sector s that satisfies one or more of the following conditions, then QRABps is set to a busy value: (1) the sector s is the serving sector before accessing the terminal; (2) The DRCLock bit from sector s is out of lock and sector s is 卩丨1 (^81^1^11111, 5 is greater than a threshold; (3) DRCLock bit from sector s is locked and sector s PilotStrengthn, s is greater than a threshold. Otherwise, QRABps is set to a value. (AN 1204 can use the DRCLock channel to inform AT 1206 whether AN 1204 successfully received the DRC information sent by AT 1206. For example That is, the DRCLock bit is sent via the DRCLock channel (eg, indicating "Yes" or "No"))) In the embodiment of determining QRABps, the current power allocation 1238a may be increased when QRABps is idle, and may be The QRABPS is reduced at busy time. Centralized Control for Each Reverse Link Carrier Figure 18 illustrates an embodiment involving centralized control in which the AT 1806 sends a request message 1866 to the scheduler 1840 on the AN 1804. Figure 18 also illustrates the dispatch of an authorization message 1842 to the scheduler 1840 of the AT 1806. In some embodiments, scheduler 1840 can actively send authorization message 1842 to AT 1806. Alternatively, scheduler 1840 can send authorization message 1842 to a request message 1866 sent by AT 1806 to AT 1806. Request message 1 866 contains AT power headspace information and a per-stream queue length of 115031.doc • 30· 1336195. Figure 19 illustrates that AT 1906 can be maintained to cause AT 1906 to determine when to send request message 1866 to AN 1 Information of 804. As shown, 'AT 1906 can be associated with a request ratio 1968. The request ratio 1968 indicates that the request message size 1866 sent on the reverse traffic channel 2〇8 is on the reverse traffic channel 208. The ratio of the transmitted data. In some embodiments, when the request ratio 1968 is reduced below a certain threshold, the AT 19〇6 sends the request message 1866 to the scheduler 1840. The AT 1906 can also Associated with a request interval 1970. The request interval 1970 indicates a time period since the final request message 1866 was sent to the scheduler 1840. In some embodiments, when the request interval increases above a certain threshold, the AT 1906 will Request message 1866 is sent to scheduler 1840. The two methods used to trigger request message 1 866 can also be used in common (i.e., can be sent when either method causes request message 1866). FIG. 20 illustrates an exemplary interaction between scheduler 2040 and AT 2006 executing on AN 2004 within sector 2032. As shown in FIG. 20, scheduler 2040 can determine a current power allocation grant 1374 for a subset 2072 of ATs 2006 within sector 2032. An independent current power distribution grant 1374 can be determined for each AT 2006. Where AT 2006 in subset 2072 includes more than one stream 1216, scheduler 2040 can determine an independent current power allocation grant 1374 for some or all of the streams 12 16 on each AT 2006. The scheduler 2040 periodically transmits the grant message 2042 to the AT 2006 in the subset 2072. In an embodiment, the scheduler 2040 may not determine an AT for the portion of the sector 2032 that is not part of the subset 2072. The current power of 2006 is 31 115031.doc 1336195 with an authorization of 1374. The fact is that the remaining AT 2006 in sector 2032 autonomously determines its own current power allocation 1〇38a. The authorization message 2 〇 42 may include - a hold period for some or all of the current power allocation grants 1374. The hold period indication Ατ 2〇〇6 for the current power allocation grant 1374 will be used to maintain the current power allocation 1238& of the corresponding stream 12 16 at the level specified by the current power allocation grant 1374. According to the method illustrated in Figure 20, the scheduler 2〇4〇 may not be designed to fill all of the capacity in the sector 2032. The fact is that the scheduler 2〇4〇 determines the current power allocation 1038& for the AT 2006 in the subset 2072, and then effectively uses the remaining sectors 2〇32 by the remaining AT 2006 without the slave scheduler. 2040 intervention. Subset 2072 can change over time and can even change with each authorization message 2042. Again, the decision to send the authorization message 2〇42 to a subset 2072 of Ατ 2006 can also be triggered by any number of external events. The external events include detecting that certain flows 1216 do not satisfy certain QoS requirements. Figure 21 illustrates another exemplary interaction between scheduler 2140 and AT 2106 performed on AN 2104. In some embodiments, if Ατ 2106 is allowed to determine the current power allocation 2138a for stream 2116 on AT 2106, then each current power allocation 2138a will converge to a steady state value over time. For example, if an AT 2106 enters an unloaded sector 2132 having a stream 2116 with data to be transmitted, the current power allocation 213 8a for the stream 2116 will ramp up until the other Stream 2116 absorbs the throughput of the entire sector 2132. However, it may take a while for this to happen. 115031.doc -32- [:S ) 1336195 An alternative method is to cause scheduler 2140 to determine an estimate of the steady state value that each stream in AT 2106 will eventually reach. The scheduler 2140 can then send an authorization message 2142 to all ATs 2106 » in the grant message 2142, as determined by the scheduler 2140, setting the current power allocation grant 2174 for the stream 2116 equal to for the stream. Estimation of the steady state value of 2116. Upon receipt of the grant message 2M2, the AT 21 06 sets the current power allocation 213 8a for the stream 2116 on the AT 2 106 to be equal to the steady state estimate 2174 in the grant message 2142. Once this is done, then Ατ 21〇6 can be allowed to track any changes in system conditions and autonomously determine the current power allocation 2138a for stream 2116 without further intervention from scheduler 2140. Figure 22 illustrates another embodiment of an authorization message 2242 transmitted from the scheduler 2240 on the AN 2204 to the AT 2206. As previously described, the 'authorization message 2242 includes a current power allocation grant 2274 for one or more streams 2216 on the AT 22 06. Further, the grant message includes a hold period for some or all of the current power allocation grants 2274. 2276. The grant message 2242 also includes an accumulated power allocation grant 2278 for some or all of the flows 2216 on the AT 2206. Upon receiving the grant message 2242, the AT 2206 sets the accumulated power allocation 2238b for the stream 2216 on the AT 2206 to be equal to the accumulated power allocation grant 2278 for the corresponding stream 2216 in the grant message 2242 » Figure 23 illustrates some implementations In the example, the power distribution 2380 can be stored at AT 23〇6. The power distribution 2380 can be used to determine the payload size 420 and power level 422 of the packet transmitted by Ατ 23〇6 to an.

Each of the power distributions 2380 is associated with a power level 2322 for each possible transmission mode. In the illustrated embodiment, each payload size 2320 is associated with a high capacity power level 2322a and a low latency power level 2322b. The high capacity power level 2322a is the power level for the high capacity packet 524a having the corresponding payload size 2320. The low latency power level 2322b is the power level for the low latency packet 524b having a corresponding payload size 2320. FIG. 24 illustrates a plurality of transmission conditions 2482 that may be stored at AT 2406. In some embodiments, transmission condition 2482 affects the selection of payload size 420 and power level 422 for packet 524. Transmission condition 2482 includes a distributed power condition 2484. The power allocation condition 24 84 is generally related to ensuring that the AT 2406 does not use more power than the power allocated to it. More specifically, the allocated power condition 2484 is that the power level 422 of the packet 524 does not exceed the total available power 1034 for the AT 2406. Various illustrative methods for determining the total available power 1034 of the AT 2406 are discussed above. Transmission condition 2482 also includes a maximum power condition 2486. The maximum power condition 2486 is that the power level 422 of the packet 524 does not exceed the maximum power level already specified for the AT 2406. Transmission condition 2482 also includes a data condition 2488. The data condition 2488 is generally related to ensuring the payload size of the packet 524. 420 in view of AT 2406 115031.doc • 34·

The total available power of S 1336195 is 1034 and the amount of data that AT 2406 is currently available for transmission is not too large. More specifically, the data condition 2488 is that there is no lower power level 2322 in the power distribution 2380 corresponding to the lower power level 2322 for the transmission mode of the packet 524 and can carry the smaller of the two of the following: 2 The amount of data currently available for transmission; and (2) the amount of data for the total available power 1034 of the AT 2406.

PilotStrength measures the pilot power of the serving sector versus the pilot power of other sectors.

It can also be used to control the up and down ramps that the AT 206 performs autonomously. It can also be used to control 'TxT2Pmax, such that AT 206 in poor geometry (e.g., at the edge of a sector) can limit its maximum transmit power to avoid interference in other sectors that are not desirable. In one embodiment, this can be achieved by adjusting the gu/gd ramp based on the forward link steering strength. φ In some embodiments, data condition 2488 is that there is no lower power level 2322 corresponding to the transmission mode for packet 524 in power distribution 2380 and is capable of carrying a payload of the size given by Payload size 2320: /e/r min^ n, T2PConversionFactorm x PotentialT2POutflowi m ) (11) In Equation (11), 4, „ is the stream from the sub-packets included in the sub-frame (2616) The amount of data.

Step 2502 involves selecting a payload size 2320 from power distribution 2380. Step 2504 involves identifying the selected payload size 11503I.doc-36- <:S with the transmission mode for packet 524. 1336195 2320 associated power level 2322.

If the packet is to be transmitted in a low latency mode, then step 25() 4 involves identifying a low latency power level 2322b associated with the selected payload size 2320. Step 2506 involves: if the packet 524 is selected If the payload size 232 〇 and the corresponding power level 2322 are transmitted, it is determined whether the transmission condition 2482 is satisfied. If it is determined at step 2506 that the transmission condition 2482 is satisfied, then at step 2508 the selected payload size 232 and the corresponding power level are selected. Passed to the physical layer 312. ♦ At step 2506, it is determined that the transmission condition 2482 is not met, then a different payload size 232 is selected from the power distribution 2380 at step 2510. The method 2500 then returns to step 2504 and as above The description continues with the basic design mechanism associated with the multi-stream allocation being equal to the total available power for each of the access terminals 2606.

'Access terminal 2606 stream when the transmission power is limited Further arbitration of power distribution is necessary. As discussed above, when there is no power limit, the gu/gd demand function determines the current power allocation for each stream via the normal function of the RAB and the flow ramp. In the case where AT 2606 power is limited, a method for setting the allocation of stream 2616 considers the AT 2606 power limit to be strictly similar to sector power 115031.doc • 37· 1336195

limit. Typically the 'sector has a maximum received power criterion for setting the RAB' which in turn causes a power allocation for each stream. The idea is: when the power of Ατ 2606 is limited, if the power limit of AT 26〇6 is actually the corresponding limit of the received power of the sector, then each stream in AT 2606 is set to the power allocation to be received. "This flow power allocation can be directly determined from the gu/gd demand function by executing a virtual rab inside the AT 2606 or by other equivalent algorithms. In this way, the flow priority within Ατ 26〇6 is maintained and aligned with the flow priority between AT 2606. In addition, information beyond the existing fat and gd functions is unnecessary. An overview of the various features of some or all of the embodiments described herein will now be provided. The system allows the average resource allocation (T2pinfl〇w 2635) and how this resource is used for decoupling of packet allocation (including peak rate and peak burst duration control).

This minus 11503 丨.doc •38- 1336195 ^ brings the network close to its proper allocation ("rough" allocation) time, and then, the autonomous mode quickly reaches the final allocation fine "allocation. Scheduler 2640 can send authorizations to a subset of streams 2616 and allow other executions to perform autonomous allocations. In this way, resource guarantees can be made to certain critical flows, and then, if appropriate, the remaining flows autonomously "fill" the remaining amount. The scheduler 2640 can implement a -"shepherding" function in which the transmission of the authorization message occurs only when the flow does not satisfy the Q〇S requirement. Otherwise, the flow is allowed to autonomously set its own power allocation. QoS guarantees can be minimized for signal transmission and consumption. It should be noted that to achieve the Q〇s target for the flow, the watch scheduler 2640 can authorize a power allocation that is different from the autonomously assigned fixed point solution. Each stream design of the up and down ramp functions is specified. The appropriate selection of this ramp function allows the average resource allocation for any of the streams 2616 to use only the purely autonomously manipulated designation of the bit control information in each sector. Very fast timing implicit in the QRAB design (updated every slot and filtered with a short time constant at each AT 2606) allows very tight control of the power distribution of each stream and maximizes total sector capacity While maintaining stability and coverage, control of each stream 2616 of peak power is allowed as a function of average power allocation and sector load (FRAB). Allows to weigh the timeliness of bursty traffic and the effect on the load and stability of the total sector 1432. Allows the maximum transmission rate of the peak power rate of 115031.doc • 39· 1336195 (P〇Wer rate) by using BurstDurationFactor The control of each stream 2616 of duration. Combined with peak rate control, this allows control of the stability and peak load of sector 1432 without central coordination of autonomous stream allocation and allows for adjustment of the need for a particular source type. The allocation is handled by the bucket mechanism and the persistence of T2pinfl〇w 2635, which allows the mapping of the average power distribution to the arrival of the burst source while maintaining the control of the average power. The filter time constant of T2pinfl〇w 2635 controls the following durations: During this duration, sporadic packets 5 24 are allowed to arrive, and beyond this duration, T2pinfi〇w 2635 decays to a minimum allocation. The dependence of the T2PInflow 2635 ramp on frab 1548 allows for a higher of the less loaded sectors 1432. Slope dynamics without affecting the final average power distribution. In this way 'can be implemented positively when the sector is less loaded Slopes, while maintaining good stability at high load levels by reducing slope enthusiasm. Based on flow priority, data requirements and available power, D2?11^1 (^ 2635 is self-tuned for Given a proper allocation of stream 2616.

In this way, the flow 2616 in the bad channel conditions can be A lower allocation is achieved, thereby reducing interference and improving the overall capacity of the system, or obtaining a full allocation independent of channel conditions, which maintains uniform behavior at the expense of system capacity. This allows for fairness/general well-being control. Possibly, the power allocation between AT 2606 and AT 2606 for each stream 2216 is as position-independent as possible. This means that the other streams 26丨6 are not important at the same AT 2606 or other AT 2606, stream The allocation of 2216 depends only on the total sector load. Some entity fact limits can achieve this goal well, especially for maximum AT 26〇6 transmission power and for combined high capacity (HiCap) and low latency (L〇Lat) Flow 2616 Consistent with this method, the total power available for AT 2606 packet allocation is the sum of the power available for each of AT 26〇6, subject to the transmission power limitation of AT 2606. The data distribution of each stream 22 16 included in the packet allocation is still based on the bucket extraction to maintain accurate accounting of the resource usage of the stream 22 。 6. In this way, the fairness of the stream is guaranteed for any data distribution rule. When the AT 2606 is power limited and cannot accommodate the total power available for all of its streams 2616, the power from the parent stream suitable for less power available in the AT 26〇6 is used. That is, although the flow within the AT 2606 is only Sharing one sector and its maximum power level with their AT 2606 (AT 26〇6 power limit is similar to the power limit of the sector as a whole), but the flows within AT 26〇6 maintain appropriate priority with respect to each other. The remaining power in the sector that is not used up by the power limited AT 2606 is then available to other streams 2616 in the sector as usual.

115031.doc S 1336195 The high-capacity stream 2216 can be merged into a low latency transmission when the sum of the high-capacity potential data usage in an AT 2606 is sufficiently high that no consolidation would result in a large power difference across the packet 524. This maintains the smoothness of the transmission power suitable for the self-interference system. When a particular high-capacity stream 2216& has a delay requirement such that it cannot wait for all of the low latency streams 2216b in the same 〇τ 26〇6 to be transmitted, the high-capacity stream 2216a can be merged into the low-latency transmission towel. Threshold of data use, flow

Their data can be combined in a low latency transmission. Because A, when _AT fiber is shared with the continuous low latency stream 2216b, the delay requirement for the high-capacity stream 2216& can be satisfied. When the sector is slightly loaded, the high-capacity stream can be merged into the low latency transmission. The efficiency loss in transmitting the high-capacity stream 22^ as a low latency is not important, and thus the merge can always be allowed. The size of the packet used by the field for the valley model will be at least y Thresh when it is ’ even if there is no effective low latency stream m6b.

Still: Transfer in low latency mode—group high capacity (four) heart. This allows the mode stream in the gate to achieve the highest throughput when its power allocation is high enough because the highest throughput for the AT 2606 occurs in the maximum packet 524 large 2 low latency transmission mode. In other words, the high-capacity transmission of the poem is very much lower than the peak rate of the low-waiting phase transmission, thus allowing high::2: The machine 221 "uses the transmission between the lower waiters Bf when it achieves the highest throughput." 16 8 has a limit on its maximum power allocation 2T2Pmax parameter. It can be determined by the location in the network (for example, when in two sectors U5031.doc

-42. When the AT 2606 at the S boundary produces additional interference and affects stability), it may also be necessary to limit the total transmission power of the AT 2606. The parameter TxT2Pmax can be designed as a function of ?11〇18, 6叩111, and limits the maximum transmission power of the eight-but 2606. Figure 26 is a functional block diagram illustrating one embodiment of AT 2606. The AT 2606 includes a processor 2602 that controls the operation of the AT 2606. Processor 2602 can also be referred to as a CPU. Memory 2605, which may include read only memory (ROM) and random access memory (RAM), provides instructions and data to processor 2602. Portions of memory 2605 may also include non-volatile random access memory (NVRAM). The AT 2606, which may be embodied in a wireless communication device such as a cellular telephone, may also include a housing 2607 that includes a transmitter 2608 and a receiver 26 10 to allow data to be remotely located at the AT 2606 and such as the AN 2604. Transmission and reception between locations 'such as audio communication. Transmitter 2608 and receiver 2610 can be combined into a transceiver 2612. Antenna 26 14 is attached to housing 2607 and is electrically coupled to transceiver 2612. Additional antennas (not shown) can also be used. The operation of transmitter 2608, receiver 2610, and antenna 2614 is well known in the art and will not be described herein. The AT 2606 also includes a signal detector 2616 for detecting and quantizing the level of the signal received by the transceiver 2612. Signal detector 2616 is known in the art to detect signals such as total energy, pilot energy per pseudo noise (PN) wafer, power spectral density, and other signals. The state changer 2626 of the AT 2606 controls the state of the wireless communication device based on the current state and the additional signals received by the transceiver 26 12 and detected by the signal detector 2616. The wireless communication device can operate in any of a number of states 115031.doc - 43 · 1336195. The AT 2606 also includes a system determinator 2628 for controlling the wireless communication device and determining to which service provider system the wireless communication device should be transmitted when it determines that the current service provider system is insufficient. The various components of the AT 2606 are coupled together by a busbar system 2630, in addition to the data busbars. The busbar system can also include a power bus, a control signal bus, and a status signal bus. However, for clarity, the various busbars are illustrated in Figure 26 as busbar system 2630. The AT 2606 can also include a digital signal processor (DSP) 2609 for processing signals. Those skilled in the art will appreciate that the AT 2606 illustrated in Figure 26 is a functional block diagram rather than a list of specific components. Multi-Carrier Multi-Stream Reverse Link Media Access Control The embodiments described above may be directed to a single carrier system where RLMAC buckets may be used for each stream 2216 to organize and control access in the T2P domain. The various devices and methods described herein can also be implemented in a multi-carrier, multi-stream system in which each access terminal can transmit, consume, and consume independently or collectively over multiple carriers (eg, frequency bands). Signal signal. For example, if the carrier has a frequency band of 1.25 MHz (million Hz), the 5 mHz band may include 3 or 4 carriers. In a multi-carrier embodiment, AT 2606 can have multiple application flows 2216 executing in parallel. Such application streams may be mapped to a MAC layer stream in AT 2606, where the mapping may be controlled by AN 2604 (eg, under centralized control). AT 2606 may have a maximum of transmissions available for all assigned carriers. Total amount of power. The MAC at AT 2606 determines the amount of power to be allocated to each stream 26i6 on each assigned carrier to satisfy various constraints, such as the QOS constraints of stream 2216 (e.g., delay, jitter, error), 115031.doc -44 - 1336195 Rate, material), network load constraints (for example, RgT, load in each sector, etc.), and so on. The MAC may be designed such that the AN 2604 determines a centralized set of parameters, some of which are stream dependent, while other parameters are carrier dependent, while at 2606 determines each physical layer packet for each of the streams 2216 in each carrier. Power allocation. Depending on various design goals, 选择 26〇4 can be selected to control the streams that reside in the same 以及 26〇6 and reside on different Ατ across different carriers in the network by determining the appropriate set of centralized parameters. The stream 22 16 of the stream 22 16 is allocated. Organizing the data stream in the multi-carrier system, such as illustrated in FIG. 27, when assigning a plurality of RL carriers to Ατ 26〇6, the data stream 2216 access control system assigned to each of the RB carriers of the AT 2606 is used by The two independent token bucket groups of each MAC layer stream 2216 are decoupling from the stream 2216 at AT 2606. (This may be different from the stream 2216 access control and stream 2216 data collation is a single carrier embodiment coupled by a single-bucket mechanism). The data generated by application stream 2216 is first adjusted by the collation bucket 2636a defined in the data field (for collation of data stream 2216). In one embodiment, there is a single collating function per stream 2216. This collating function ensures that the average and peak resources utilized by stream 22 16 are less than or equal to a limit. In an embodiment, stream 2216 (or Ατ 26〇6) may not abuse additional allocations in the multi-carrier system and perform grooming in the data domain. I15031.doc, 45. When the stream 2216 data is organized in the RTC MAC layer, the following steps shown in Fig. 28 are performed. First, the AN 2604 configures the following data token bucket attributes (step 3010): The data token bucket for the MAC stream i (22l6) 2 6 3 6 a maximum size (in octets). The data entry into the bucket 2636a for each sub-frame (in octets) for MAC stream i (2216) is entered into the stream. The stream of the sorting bucket 2636a for each sub-frame (in octets) for the MAC stream i (22l6) is recorded. Then, by setting the data token bucket (or the bucket 2636a) level DataTokenBucketlevel i to the maximum bucket level DataBucketLevelMaXi^. H^· ^ MAC ^ i(2216) ffij initialization (step 3020), which can be expressed for:

DataTokenBucketleveli = DataBucketLevelMaXi (12) Subsequently, at the beginning of each subframe n, the maximum allowed outflow from the data token bucket (or bucket) 2636a for each valid MAC stream i (2216) is calculated and will The total available power for the bin 2636a is set equal to this maximum, or if the maximum is negative, it is set to zero (step 3030). The total available power for the data outflow of the bin 2636a can be expressed as:

PotentialDataTokenBucketOutfloWin = max {DataTokenlnfloWi + DataTokenBucketLeveliw 0) (13) where 1 indicates ^1 八0 stream 2216, 11 indicates the sub-frame, 1) as <37'〇^:6«_/>2//〇\^ Indicates the current data allocation 2639a for stream i (2216), YU 115031.doc -46- 1336195 • DataTokenBucketLevelin ^^^>;1ΐΐ(2216)^, Accumulated data allocation 2639b. Next, it is determined whether this is a new packet allocation (step 3040). If the answer to step 3040 is no, then go to step 3060. If the result of step 3040 is 'Yes, then the following step 3050 is performed during the new packet allocation in frame n of each assigned carrier j. If the total available data for the bin 2639a for the stream i (2216) is equal to zero (step 3050), then it can be expressed as: • PotentialDataTokenBucketOutflow in — 0 (14) Subsequently, it will be used for the high capacity packet 524a The total available power of the ith stream on the jth carrier is 1238 corpse to ^^<3/77/>0«(/7〇14^,7.,//(: is set equal to zero, and will be used The total available power of the ith stream (2216) on the jth carrier of the low latency packet 524a is set to equal zero (step 3055). This equation can be expressed as:

PotentialTIP Outflow ijuc = 〇 (15) PotentialT2POutfloWijii = 0 (16) where i denotes the MAC stream 2216, j denotes the jth carrier, η denotes a subframe, HC denotes a high capacity, and LL denotes a low latency. If the result of step 3050 is no, then go to step 3060. This ensures that the power of the stream to be allocated to each of the assigned RL carriers at the AT is set to zero when the stream exceeds the allocation of the bucket. Next, it is determined whether this is the end of the subframe η (step 3060). If the answer to step 3060 is no, then return to step 3030. If the answer to step 3060 115031.doc -47 - 1336195 is YES, the data token bucket for each valid MAC stream i (2216) is updated at the end of each subframe n by the following steps. Standard: Set the data bucket level for frame n+1 to be equal to the current data allocation for stream i (2216) 2639a DataTokenlnflowi plus for sub-frame n (2216) for data stream i (2216) The accumulated data allocation 2639b, minus the number of octets from the MAC stream i (2216) contained in the payload of the sub-frame n in all carriers j 2^(:(^,11 or The data in stream i (2216) is the minimum value of the maximum size DataBucketLevelMaXi of the bucket 2636a (step 3070). This can be expressed as:

DataTokenBucketLevelin+i = mm(DataTokenInfioWi + DataTokenBucketLevelin -

DataBucketLevelMaxi) (17) where du,n = the number of octets from the MAC stream i (22 16) contained in the payload of the subframe n in the carrier j, C = assigned to all of the AT 2606 The set of carriers, [" is the number of octets from the MAC stream i (22 16) contained in the payload of the sub-frame n in all carriers j, and the DataTokenlnflowi is used for the stream i (2216) The current data allocation 2639a, DataTokenBucketLeveli, n is the accumulated data allocation 2639b for the data stream i (2216) in the subframe η, and the DataBucketLevelMaxi is the data token bucket 2636a for the stream i (2216). size. Return to step 3030. The output of the data field token bucket 2636a is then adjusted by a second set of token buckets 2636b defined in the T2P or power domain. These second buckets or stream access buckets 263 6b are determined for each of the MAC flows 2216 in each of the assigned carriers.

' S 115031.doc -48 - 1336195 Potentially allowed transmission power. Thus, each second bucket 2636b represents an assigned carrier and a stream 2216 located on the carrier. Thus, under multi-carrier, flow 2216 access is controlled on a per-carrier basis, where the number of assigned rLmaC buckets can be equal to the number of carriers assigned to each stream 2216. Figure 2 illustrates an example of streamlining self-access control, where data is first placed in a stream collation (or source control) bucket 2636a for the stream 2616 and then constrained by a peak outflow Conditionally, the data is assigned to different carriers using a set of carrier selection rules 2639c, which in one embodiment can be stored in memory as instructions executable by the processor or processor component. Each of the N carriers has its own access control bucket 2636b labeled 1 to n corresponding to 1 to N carriers. Thus, the number of buckets 26; 36b can be set equal to the number of assigned carriers for each stream 2216. The final power allocation for each of the streams 2216 in each carrier is then determined by using the output of the token bucket 263 6b based on the second T2P domain and a set of rules defined below. Carrier Selection Strategy at AT 26〇6 The AT 2606 ranks all assigned carriers based on a metric. The average transmit power (TxPil〇tP〇wer) of the pilot signal of AT 2606 in one embodiment can be used as a carrier level metric. If the carrier with the lowest average TxPilotPower in the given sub-frame is not available for new packet allocation, then other lower-level carriers are used. The filter time constant used to average TxPil〇tp〇wer has the following effect "AT 26〇6 can benefit from the use of short-term fading variations by using smaller filter time constants. On the other hand, 115031.doc -49-

The longer time constant of S 1336195 reflects the long-term variation of the total interference observed by AT 2606 in each assigned RL carrier. It should be noted that the average FRAB 1548 or average TxPilotPower and average FRAB 1548 functions are also a possible measure. The AT 2606 distributes the packets on each carrier based on the level of the packet until the AT 2606 runs out of data, the PA headspace, or the carrier. The multi-carrier RTC MAC of the method and apparatus may iterate (add or revoke) via assignment of carriers based on the assigned carrier level until AT 26〇6 has no data or no pA headspace.

The signal-to-noise ratio (SNR) can also be used as a metric. AT 26〇6 achieves load balancing by supporting carriers with lower interference. AT 2 6 6 6 is transmitted via a subset of assigned carriers to operate in more Eb/N() active modes to minimize each transmitted bit summed over all assigned carriers for the same achieved data rate. The energy needed.

Another metric that can be used is interference. The AT 26〇6 utilizes frequency selective fading across the assigned carrier and, where possible, obtains multi-frequency diversity gain by supporting power allocation to carriers having lower interference (4) within a smaller time scale. The AT 2606 attempts to maximize the number of bits transmitted per unit of power by supporting power allocation (or first allocated power) for carriers having lower interference placed within a longer time scale. Alternatively, the incoming τ 2606 is achieved by minimizing the transmission power for a given packet 524 size and, if possible, by selecting the carrier to achieve the final assignment on each of the assigned carriers. The interference observed by the AT measurement transmission pilot power or the inverse significant bit 2606 can be indirectly measured by the measurement 。. These two degrees H5031.doc f can be averaged over the time scale. The time scale determines the trade-off between the response in the noise due to less averaging and the response to the over-smoothed metric due to excessive filtering. In a further embodiment, AT 2606 may classify all assigned carriers using a combination of metrics including, but not limited to, the metrics recited above. " 2606 may determine the shoulder carrier based on the pa headspace and (possibly) data considerations. In one embodiment, AT 26〇6 chooses to cancel the carrier with the highest ^ TxPU 〇 tP0wer (averaged over a period of time). The transmission of Eb/N〇 active mode across many assigned carriers includes: for the same total data rate of access, and end machines, the bandwidth required to support each bit in the linear region is larger for the packet size The transmission of the number of carriers, as opposed to the transmission of the energy required per bit in the non-linear (convex) region, is the opposite of the transmission of a smaller number of carriers. The mac layer cooperates with AN 2604-AT 2606 Achieving load balancing across carriers. The load balancing time scale can be divided into two parts: “Short-term load balancing” and “Average load balancing β AT 26〇6 are distributed in a decentralized manner by the assignment for the base; Appropriate selection between carriers is used to achieve short-term load balancing. Examples of short-term load balancing include: i) AT 26G6 water-fills power across all assigned carriers when RAB 1444 or packet 524 is size-sized in each assigned carrier; and η) ατ 26〇6 at power (ie, , PA headspace) is transmitted via a subset of assigned carriers when restricted. The AN 2604 achieves long-term load balancing by appropriately determining the parameter for the flow across the carrier by arranging the carrier to the AT 26〇6 in the time scale of effective set management and arrival of the new flow. ο “ο* The locality determines the fairness and long-term power allocation for each of the flows 2216 across each assigned carrier in the network by determining the MAC flow 2216 parameters discussed above by I I503I.doc 51 1336195. Carrier Allocation of 2642 FIG. 29 illustrates an embodiment involving centralized control in which AT 2606 sends a carrier request message 2666 to scheduler 2640 on AN 2604. Figure 30 also illustrates the transmission of carrier grant message 2642 to AT 2606. Scheduler 2640. AN 2604 and AT 2606 can cooperate using a message driven mechanism to find the best carrier allocation for the network. Similar to the existing T2P Inflow request authorization mechanism used in the single carrier embodiment discussed previously, The AT 2606 and AN 2604 respectively use the carrier request message 2666 and the carrier grant message 2642. In the AT 2606 drive mode, the AN 2604 relies on the AT 2606 requesting additional carriers when the data and PA headspace are verified to be correct. In the AN 2604 drive mode The AN 2604 allows all AT 2606 to periodically transmit data, TxPilotPower, FL pilot strength, and PA headspace information, which AN 2604 can use to determine When to assign a carrier to AT 2606. Carrier request message 2666 may be asynchronous with carrier grant message 2642. AT 2606 may send a carrier request message 2666 to AN 2604 for increase/decrease in the number of carriers. Again, AT 2606 may The number of assigned carriers is autonomously reduced when the AT 2606 is limited by the link budget, but the AN 2604 is notified after the carrier is revoked. The AT 2606 sends a carrier request message 2666 to increase the number of assigned carriers when the data and PA headspace are verified to be correct. And reduce the number of assigned carriers when the PA headspace or data makes the current number of carriers inefficient. AT 2606 carrier request message 2666 may contain flow QoS requirements, flat

The AN 2604 can use carrier grant message 2642 to authorize the carrier based on criteria such as AT 2606 request message information and load balancing FL consumption. The AN 2604 may choose not to transmit the carrier grant message 2642 in response to a carrier request message 2666. The AN 2604 can use the carrier grant message 2642 to add/reduce/reassign the assigned carrier for each AT 2606 at any time. In turn, AN 2604 can also reassign the carrier for each AT 2606 at any time to ensure load balancing and efficiency or reassign the carrier for each AT 2606 at any time based on FL demand to ensure load balancing and efficiency. The AN 2604 can reduce the number of carriers for each AT 2606 at any time. The AN 2604 may revoke one carrier and assign another carrier to the given AT 2606 at any time - the AT 2606 service is uninterrupted when other carriers are enabled at the AT 2606 during the handover procedure. The AT 2606 follows the AN 2604 carrier grant 2642. In an embodiment, a priority function can be used to perform flow access control per carrier. The per-carrier allocation is similar to the allocation for a single carrier system and can be the same across all carriers. As the number of carriers assigned to the terminal changes, there is no need to change the RTC MAC bucket parameters. As with the single carrier embodiment, the ramp rate on each carrier is limited by the maximum allowable interference. Carrier Allocation and Management In a multi-carrier system, the number of carriers assigned to the AT on the forward link (FL) can be, for example, based on AN information based on the data and QoS requirements associated with the AT on the FL. To judge. Assigned to the AT on the reverse link (RL)

As further described below, the number of carriers assigned to the octet can also be determined, for example, by an with respect to the schedule information received from Ατ. For example, there may be multiple FL carriers and multiple RL carriers associated with Ατ. The number of FL carriers may be the same as the number of strong carriers (e.g., in a symmetric mode of operation) or different than the number of RL carriers (e.g., in an asymmetric mode of operation). There may also be a single RL carrier associated with the AT and a plurality of 1:1 carriers (e.g., a particular case of asymmetric mode of operation) or a single RL. A single FL carrier (e.g., a particular case of symmetric mode of operation). As further illustrated by the examples described below, the allocation and management of several and a few carrier carriers can be performed dynamically. In an implementation, the AN may determine the number of FL carriers to be indexed to eight, as a function of one or more carrier allocation parameters, and assign an assignment message based on the determination (eg, a message in an IS.856 type system) A channel assignment (tca) message or a radio bearer reconfiguration message in a W-CDMA type system) is sent to the AT.

The scheduling information may also include a subset of the number of additional RL carriers that the AT needs to have or a subset of previously assigned RL carriers that the AT intends to revoke (or have revoked). For example, as further described below, the AT can determine the number of RL carriers required as a function of one or more carrier decision parameters. The carrier decision parameters disclosed herein may include one of the following parameters: a data requirement associated with an AT on the RL, a QoS requirement for one or more flows associated with the AT on the RL (eg, based on one or Transmission power (or power headspace) of available sRL transmissions at the AT (which may be based, for example, on an average transmission guide associated with each RL carrier assigned to Ατ) The power is used to determine the buffer state associated with Ατ (eg, in a W-CDMA type system), and the amount of FL related information to be transmitted on rl (eg, based on the fl carrier assigned to Ατ) Number), the location of the AT on the RL, and the total (including intra-sector and inter-sector interference) observed by the AT, the sector load on the RL (or the average sector load per carrier) (AT can be monitored based on Each carrier's RL in the sector is used to determine it, hardware constraints associated with the AT (eg, the ability to transmit, track, and manage multiple carriers), and so on. The term "undo" with respect to the carrier disclosed herein may refer to stopping (or terminating) all transmissions on the carrier (e.g., associated with steering, traffic/data, and consumption channels). Further description of carrier allocation and management is provided below. An example. In an example, an AT may initially send a plurality of access probes on a random hashed RL carrier (eg, 'trying to distribute evenly from across all available

115031.doc • 56-, S 1336195 RL load generated by access probes of different ATs of the RL carrier). As explained further below, in response, the AN may decide to assign one or more carriers to the AT, which may be different than the carrier to which the AT previously sent the access probe. Figure 30 illustrates a call flow diagram 3000 illustrating one example of carrier allocation and management in a multi-carrier communication system. At step 3010, the AT 3001 transmits an access probe on the initial or predetermined RL carrier (e.g., by a hash function) to the AN 3002. At step 3020, upon decoding the access probe, the AN 3002 sends an access channel acknowledgment (shown herein as "AC-ACK" for abbreviations and conciseness) to the AT 3001. At step 3030, AN 3002 determines (e.g., by performing a carrier management algorithm) the number of FL and RL carriers to be assigned to AT 3001. AN 3002 may also identify FL and RL carriers to be assigned to the AT that are different from the carrier originally detected by AT 3001. At step 3040, the AN 3002 sends an assignment message (shown herein as "TCA" for abbreviations and conciseness) to AT 3 001 indicating the FL and RL carriers assigned to AT 3 001 and the AT 3001 A reference value (herein referred to as "TxInitAjust") that can be used to determine the initial transmission pilot power on each newly assigned RL carrier. At step 3050, AT 3001 sends an ACK to TCA (shown herein as "TCC" for abbreviations and conciseness) to AN 3002. At step 3060, AT 3 00 1 determines each recent assignment based on TxInitAjust. The initial transmission pilot power on the RL carrier.

In Figure 30, for example, the AT 3001 may initially transmit an access probe on a first RL carrier. In addition to the first RL carrier, the AN 3002 can then assign a second RL carrier (different from the first RL carrier) to the AT 3001. AN 5 ) 115031.doc • 57- 1336195 3002 may also assign a second RL carrier to AT 3001 in place of the first RL carrier. In such cases, AN 3002 can be sent for Ατ 3〇〇1

TxInitAjust (e.g., included in the TCA) to determine the initial transmission power on the second 1:1 carrier. In an example, the AT can be initially assigned a single carrier on each of the FL and RL. Behind the heart, you need to add more carriers on the FL and / or RL. The trigger for adding more carriers can be initiated by the AT, for example, with respect to a new valid MAC stream with more information and/or improved available transmission power. The triggering for adding more carriers can also be initiated by an, for example, with respect to load condition changes on the RL and/or new valid MAC flows for a few Ατ, and so on. Figure 31 shows a call flow diagram 31, which illustrates an example of adding more carriers to an AT. At step 3 110, AT 3〇〇1 determines the number of fl and rl carriers required (e.g., by performing a carrier management algorithm). If the result indicates that more carriers are needed, then at step 3120 the AT sends a request message to AN 3002. At step 313, the AN 3002 determines whether an additional carrier is allocated to the AT 3001. At step 3140, AN 3〇〇2 sends a TCA indicating the additional carrier to be assigned to AT 3001 and TxInitAjust associated with each newly assigned rl carrier (if any) to AT 3001. At step 3150, the AT 3001 sends the TCC to the AN 3002. At step 3160, AT 3001 determines the initial transmission power on each newly assigned iRL carrier based on TxImtAjust. In the case where the AN 3002 can start adding more carriers, the an 3002 can receive messages from the AT 3001 (for example, 115031.doc • 58 in the IS 856 system (S:, routing update message) Acquiring the FL and RL related information e AN 3〇〇2 may then determine (eg, by performing a carrier management algorithm) a new set of L and RL carriers to be assigned to the AT 3 operator. Such as described above, AN 3〇〇2 can send the TCA of the new carrier (and TxInitAjust for each newly assigned rl carrier) to AT 3〇〇丄. In the example, the initial (or previous) can be The AT assigns multiple carriers on both the FL and the RL. The AT may then decide to revoke a subset of the previously assigned RL carriers. The trigger for revoking the carrier at the AT may be attributable to various factors including, but not limited to, : The AT again has a link budget constraint and may not be able to successfully enclose the RL on all assigned carriers (in other words, successfully maintaining the predetermined packet error rate on the RL). For example, due to transmission power limitations, the AT may not be able to do it at all. The RL carrier successfully communicates with the AN. The τ can be caused to revoke a subset of the previously assigned RL carriers and successfully communicate with the AN on the remaining rl carriers using the available transmit power. There is transmission power inefficiency on the RL. For example, Ατ can have sufficient power to close the link And communicate with the eight\; however, according to the power usage of VIII, it may be inefficient to support multiple RL carriers. In these cases, 八1 can be used by the RLs channel that is not transmitted on multiple RL carriers. The cost is better to use the available power to transmit on a subset of the assigned RL channels. The AT is limited by data and may not be interested in paying for the cost of the additional overhead channel associated with the unused rl carrier. Figure 32 shows a call Flowchart 32A illustrates an example in which the restricted link budget can be used to trigger the revocation of certain RL carriers starting at 115031.doc - 59. 1336195. At step 3210, the AT 3001 revokes the child of the previously assigned RL carrier. The set such that the available transmit power is sufficient to successfully close the link on one or more of the remaining RL carriers. At step 3220, the AT 3001 will indicate a subset of the previously assigned 2RL carriers that were revoked and The base cause request message is sent to AN 3002. In response, at step 3230, AN 3 002 sends TC A to AT 3001, which indicates the number of FL carriers assigned to the AT and the FL related consumption channel pair and Mapping of the remaining RL carriers associated with at 300 1. Figure 33 shows a call flow diagram 3300' illustrating an example of a transmission power inefficiency that may initiate a trigger for revoking certain RL carriers. At step 33 1 , AT 3001 Determine the number of previously assigned rl carriers that it needs to revoke. At step 3320, the AT 3001 sends a request message indicating the number of previously assigned RL carriers and the underlying cause to which it intends to revoke to an 301. The AT 3001 can wait for a confirmation (or verification) from aN 3〇〇2 before actually canceling any RL carriers. At step 3330, the AN 3002 sends the TCA to the AT 3001 'The TCA indicates the number of FL and RL carriers assigned to the AT 3001 and the remaining carrier-associated mapping of the FL-related drain channel pair associated with AT 3〇〇1. . Once the TCA is received, at step 3340, the AT 3001 performs a FL mapping of the consumed lanes. To provide smooth transmission, at step 335, the AT 3001 simultaneously transmits the FL related consumption channel for a certain (e.g., short) duration on all assigned RL carriers. Thereafter, as illustrated in step 3360, the AT 3001 revokes the previously assigned ruler [all subsets of carriers. In the case where the data limit can be initiated to revoke the triggering of certain RL carriers, the AT 3001 may decide to revoke only the unloaded fl-related rl load 115031.doc • 60- 1336195 'wave. For example, AT 3001 may first 'instruct it in the request message to AN 3002 and suppress undoing any RL carrier until an acknowledgment (e.g., TCA) is obtained from AN 3 002, such as described above. In an example, the AT can be initially assigned a single carrier on each of the FL and RL. The AN may then decide to change the previously assigned RL carrier to a new (or different) carrier. For example, the trigger used to change the RL carrier assignment by the AN can be attributed to a change in the AT location while the AN uses a location based carrier allocation algorithm. ♦ Figure 34 shows a call flow diagram 3400 illustrating an example in which an AN can initiate a new RL carrier assignment. At step 3410, a single carrier on each of the FL and RL is initially (or previously) assigned to the AT 3001. At step 3420, AN 3002 obtains FL and RL related information (eg, transmission power availability at AT 3001, AT-based average FL signal interference noise ratio (SINR) AT position, etc.), for example, obtained from one Messages received from AT 300 1 (eg, routing update messages). Based on this information, AN 3002 decides to change the RL carrier of the AT (e.g., by performing a carrier management algorithm). To ensure a smoothed® transition, at step 3430, the AN sends the TCA to the AT 3001 (for example) for a short duration, the TCA indication being assigned to the two (new plus previous) RL carriers and FL of the AT 3001 A mapping of the consumed channel to the newly assigned RL carrier. After ensuring that AN 3 002 is capable of efficiently decoding all FL-related drain channels on the newly assigned RL carrier (as illustrated by step 3450), as illustrated by step 3460, AN 3 002 sends a request to AT 3 001 to revoke the previously assigned TCA of the RL carrier. At step 3470, the AT 3001 revokes the previously assigned RL carrier. 115031.doc • 61 - 1336195 The examples described above provide certain embodiments of carrier allocation and management in a multi-carrier communication system.
