TW200818826A - Semi-persistent scheduling for traffic spurts in wireless communication - Google Patents

Abstract

Techniques for efficiently assigning resources for spurts of traffic in a wireless communication system are described. The system may support semi-persistent and non-persistent resource assignments. A semi-persistent resource assignment is valid for as long as more data is sent within a predetermined time period of last sent data and expires if no data is sent within the predetermined time period. A non-persistent resource assignment is valid for a predetermined duration or a specific transmission. A semi-persistent resource assignment may be granted for an expected spurt of data to send via the communication link. For Voice-over-Internet Protocol (VoIP), a semi-persistent resource assignment may be granted for a voice frame in anticipation of a spurt of voice activity, and a non-persistent resource assignment may be granted for a silence descriptor (SID) frame during a period of silence.

200818826 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present disclosure relates generally to communications, and more particularly to scheduling techniques for wireless communications. [Prior Art] • Wireless communication systems are widely deployed to provide various communication contents such as voice, video, and packet data, messaging, and broadcasting. Such wireless systems can be multiple access systems that support multiple users by sharing available system resources. Examples of such multiple access systems include a code division multiple access (cdma) system, a time division multiple access (TDMA) system, a frequency division multiple access (fdma) system, an orthogonal fdMA (ofdma) system, and a single carrier fdma. (sc_fdma) system. The wireless communication system can include any number of base stations that can support any number of applications for fTTIR, 4 θ ---

The resources that are used as little as possible are directed to the request for resources' and the downstream key resources are given. Therefore, there is a need in the art to support techniques for improving system capacity by selling. 123916.doc 200818826 [Disclosed herein] This paper describes a technique for effectively assigning a source to a traffic burst in a wireless communication system, %", ", ".

Resource assignments that are valid at the time of loss. In one design, a semi-persistent resource assignment or a non-persistent resource indicator of a communication link (e.g., downlink or uplink) may be determined. The data may then be exchanged (eg, developed and/or received) via a communication link based on a semi-persistent resource assignment or a non-persistent resource assignment. The semi-persistent resource assignment may be granted for use via the communication link. The expected data sent was abrupt. As an example, for a VoIP protocol, a semi-persistent resource assignment may be granted for a voice frame for expected voice activity spurts, and a non-persistent resource assignment may be granted during a silence period. _ Quiet Descriptor (SID) frame. Various aspects and features of the present disclosure are described in more detail below. [Embodiment] The techniques described herein are applicable to various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and other systems. The terms "system" and "network" are often used interchangeably. CDMA systems may implement, for example, universal land radio access (Univei*sai Terrestrial)

Radio technologies such as Radio Access, UTRA, and cdma2000. UTRA 123916.doc 200818826 includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). Cdma2000 covers IS-2000, IS-95 and IS-85 6 standards. A TDMA system can implement a radio technology such as the Global System for Mobile Communications (GSM). The OFDMA system can implement radio technologies such as Evolved UTRA (E_UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM®, and the like. UTRA, E-UTRA and GSM are one of the voice points of the Universal Mobile Telecommunication System (UMTS). 3GPP Long Term Evolution (LTE) is the latest version of UMTS using E-UTRA, which uses OFDMA for the downlink and SC-FDMA for the uplink. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are from the third generation Partner Program 2, (3rd Generation Partnership Project 2, 3GPP2) is described in the documents of the organization. These various radio technologies and standards are known in the art. The techniques described herein can be used for the assignment of resources on the downlink as well as on the uplink. For clarity, certain technical aspects are described below for the assignment of resources on the uplink in LTE. The LTE terminology is used in many of the descriptions below. Figure 1 shows a wireless multiple access communication system in accordance with a design. The evolved Node B (eNB) 100 includes a plurality of antenna groups, one group including antennas ι 4 and 106, another group including antennas 108 and 110, and an additional group including antennas 112 and 114. Only two antennas per antenna group are shown in FIG. However, more 123916.doc 200818826 more or less antennas can also be used for each antenna group. In general, an eNB may be a fixed station for communicating with a UE and may also be referred to as a node b, a base station, an access point, and the like. UE 116 is in communication with antennas 112 and 114, wherein antennas 112 and 114 transmit information to UE 116 via downlink U0 and receive information from ue Π 6 via uplink 118. UE 122 communicates with antennas 1〇6 and 1〇8, where antennas I% and 1〇8 transmit information via downlink 126 to UE j22 and receive information from UE 122 via uplink 124. In general, the UE may be stationary or mobile and may also be referred to as a line, a mobile station, a terminal, an access terminal, a subscriber unit, a station, and the like. The UE can be a cellular phone, a personal digital assistant (pDA), or wireless communication. Handheld devices, wireless data devices, laptops, etc. In a frequency division duplex (FDD) system, communication links 118, 12A, 124, and 126 can use different communication frequencies. For example, downlinks 12 and 126 can use one frequency' and uplinks 118 and 124 can use another frequency. The total coverage area of the eNB 100 can be divided into multiple (e.g., three) smaller areas. These smaller areas can be served by different antenna groups of the eNB 1〇〇. In 3GPP, the term "cell" may refer to the minimum coverage area of an eNB and/or an eNB subsystem serving this coverage area. In other systems, the term "sector" may refer to the minimum coverage area and/or service coverage. Subsystem of the region. For the sake of clarity, the 3Gpp concept of the cell is used in the following description. In one design, the two antenna groups of the eNB 100 support the communication in the three cells of the work. 2 shows a block diagram of the design of eNB 100 and UE 116. In this design, the eNB 100 is equipped with T antennas 22 privately 22, and the UE ΐ6 is equipped with 123916.doc -10- 200818826 R antennas 252a through 252ir, typically T21 and RM. At eNB 100, transmit (TX) data processor 214 can receive traffic data for one or more UEs from data source 212. The data processor 214 can process (e.g., format, encode, and interleave) the traffic data of the UE based on one or more coding schemes selected for each UE to obtain encoded data. The data processor 214 may then modulate (or symbol map) the UE based on one or more modulation schemes (eg, BPSK, QSPK, M-PSK, or M-QAM) selected for each UE. Encoded information to obtain modulation symbols. The ΜΙΜΟ processor 220 can use any multiplex scheme to multiplex the modulation symbols and preamble symbols of all UEs. The preamble is typically known data processed in a known manner and the receiver can use the preamble for channel estimation and other purposes. The processor 220 can process (e.g., precode) the multiplexed modulation symbols and preamble symbols and provide the output symbol streams to a plurality of transmitters (TMTR) 222a through 222t. In some designs, the processor 220 can apply beamforming weights to the modulation symbols to spatially manipulate the symbols. Each transmitter 222 can process, for example, respective output symbol streams for orthogonal frequency division multiplexing (OFDM) to obtain an output chip stream. Each transmitter 222 can further process (e.g., analog to convert, amplify, filter, and upconvert) the output chip stream to obtain a downlink signal. The T downlink signals from transmitters 222a through 222t may be transmitted via T antennas 224a through 224t, respectively. At UE 116, antennas 252a through 252r may receive downlink signals from eNB 100 and provide received signals to receivers (RCVR) 254a through 254r, respectively. Each receiver 254 can condition (eg, filter, amplify, downconvert 123916.doc -11 - 200818826 convert and digitize) the respective received signals to obtain samples and can further process the samples (eg, with respect to OFDM) to obtain Received symbol.侦测 Detector 260 can receive and process received symbols from all R receivers 254a through 254r based on the ΜΙΜΟ receiver processing technique to obtain detected symbols, which are pairs of eNBs 100 An estimate of the transmitted modulation symbol. The receive (RX) data processor 262 can then process (e.g., demodulate, deinterleave, and decode) the detected symbols and provide the decoded data of the UE 116 to the data slot 264. Typically, the processing by the detector 260 and the RX data processor 262 is complementary to the processing at the eNB. 100 by the processor 220 and the data processor 214. On the uplink, at UE 116, traffic data and signaling messages from data source 276 may be processed by data processor 278, further processed by modulator 280, adjusted by transmitters 254a through 254r, and transmitted to eNB 100. At eNB 100, the uplink signal from UE 116 may be received by antenna 224, adjusted by receiver 222, demodulated by demodulator 240, and processed by RX data processor 242 to obtain traffic data transmitted by UE 116. And the message. Controllers/processors 230 and 27A can direct operation at eNB 100 and UE 116, respectively. The memories 232 and 272 can store the data and code of the eNB 100 and the UE 116, respectively. Scheduler 234 can schedule scheduled UEs for downlink and/or uplink and can provide resource assignments for scheduled UEs. The system supports Hybrid Automatic Repeat (HARQ) to improve the reliability of data transmission. For HARQ, the transmitter can transmit the data frame for transmission and optionally send one or more retransmissions until the data frame is correctly decoded by the receiver 123916.doc -12- 200818826 or the maximum number of retransmissions have been sent or Encountered some other termination condition. The data frame can also be called a packet, a data unit, a data block, and the like.

Figure 3 shows an exemplary data transmission on the uplink with HARQ in LTE. UE 116 may have data to transmit on the uplink and may transmit requests for uplink resources on a Physical Uplink Control Channel (PUCCH). The eNB 100 may receive a resource request from the UE 116 and may upload back an uplink resource grant on the Physical Downlink Control Channel (PDCCH). The ue 116 can process the data frame A and can transmit the frame using the granted reverse link resources on the physical uplink shared channel (PUSCH). The frame transmission can span a sub-frame, which can be 2 milliseconds (ms) in LTE but can have other durations such as 1 ms, 5 ms, 10 ms, and the like. The sub-frame can also be called the transmission time interval (ΤΤί). The eNB 1 can receive the transmission of the frame A, erroneously decode the frame A, and send a negative acknowledgement (NAK) on the acknowledge channel (ackch). UE 116 may receive the NAK and retransmit frame A. The eNB 1 can receive the retransmission of the frame a, correctly decode the frame A based on the original transmission and retransmission, and transmit an acknowledgement (ACK). UE 116 may receive the ack and process and transmit the next data frame b in a manner similar to frame A. Each transmission and each retransmission of the frame may be referred to as a harq transmission. The number of HARQ transmissions of the data frame can be determined by the modulation and coding scheme (MCS) of the data frame and the received signal quality of the data frame. Mcs can also be called rate, frame, packet, transport format, and so on. The MCS of the message frame can be selected to achieve the target HARQ termination, which is the expected number of HARq transmissions required to correctly decode the data frame. Longer target HARQ termination can improve resource utilization efficiency at the expense of longer delays. 123916.doc -13- 200818826 Q HARQ instances or interlaces can be defined, where Q can be any integer value. Each HARQ entity may include subframes separated by Q subframes. For example, six HARQ individuals can be defined, and the HARQ individual 3 can include sub-frames, 9 + 6, 9 + 12, etc., where ^{〇, ..., 5}. The HARQ process can refer to all transmissions and retransmissions (if any) of the data frame. The HARQ process may begin when resources are available and may terminate after the first transmission or after one or more retransmissions. The HARQ process can have a variable duration that can be determined by the decoding result at the receiver. Each HARQ process can be sent on one HARQ entity and up to Q HARQ processes can be sent in parallel on Q HARQ instances. The UE 116 may send a request for an uplink resource whenever the UE has traffic data to be sent on the uplink. The eNB 100 may pass the grant of the uplink resources back to the UE 116. UE 11 6 can receive bursty traffic data to be sent on the uplink. Such spikes can begin at any time and can have any duration. For example, the UE 11 6 may have a VoIP call and may receive a burst of voice material from the user in the call. VoIP applications can provide voice frames at a rate (e.g., every 10 ms or 20 ms) during bursts of voice activity and can provide SID frames at another rate (e.g., every 160 ms) during a quiet period. The UE 116 may not be known a priori when receiving a data frame for transmission on the uplink from the VoIP application. Whenever a data frame (eg, a voice frame or SID frame) is received from a VoIP application, the UE 116 may send a request for an uplink resource to the eNB 100, and receive an grant for the uplink resource from the eNB 100. And use the granted resources to transmit the data frame. However, the request on the uplink of each data frame 123916.doc -14- 200818826 and the grant on the downlink can result in high control channel consumption.

In the case, the system can support resource assignments such as those shown in Table 丨. Negative Table 袼1 Assignment Type Hold, •Right, Assign ~ 1

A resource that can be used in persistent resource assignments, usually by resources, by frequency (eg, a set of subcarriers), (iv) (eg, = period or subframe), code, transmission power, etc., or any combination thereof. It can be referred to as a pre-group (four) source, a pre-bound u source, a pre-assigned resource, and the like. The predetermined time period is also referred to as the timeout period. Semi-persistent resource assignment

= Hold, only | ± source assignment and non-persistent resource assignment can be effectively used for any application with a large material. For V()IP, semi-persistent resource assignments can be used for voice frames sent during bursts of voice activity, and non-persistent source assignments can be sent to the SID frame sent during the silence period. Semi-performance resource assignments can provide good performance for voice bursts and reduce control IC consumption. Non-performing poor source assignments can be attributed to SID frames attributable to large time intervals between the frames. Control channel consumption is attributable to the infrequent SID frame arrival. ..., when the UE 116 has information to be transmitted on the uplink, then 123916.doc 200818826 The UE may send a request for uplink resources on the PUCCH. The certificate may indicate the amount and/or type of material to be sent in the resource request. For ν〇π>, the resource request may indicate that the UE 116 has a voice frame or a frame, a voice = frame size, or a data rate. Generally, different codeword groups can be used for different bedding buffers or frame rates (for example, full rate frame, half rate frame, quarter mark, rate frame, SID frame, etc.), different types of messages. A box (eg, a compressed header v〇Ip frame and an uncompressed header ν〇ιρ frame) and/or other information indicating the amount and/or type of data to be sent. The UE 116 may select the appropriate codeword group based on the lean buffer level and may send the selected codeword group for the resource request. In one design, two codeword groups can be used for reading: - one codeword (four) for full rate speech pure and another - codeword group for S ID frame. The eNB 100 may receive resource requests from the UE 116 and may assign appropriate resources based on the request. In one design, _1〇〇 may (1) grant semi-persistent resource assignments for resource requests for voice frames or (9) grant non-persistent resource assignments for resource requests for SID frames. In a design, if multiple voice frame rates are supported, the semi-persistent resource assignment can be used for the highest supported voice frame rate (e.g., full rate). This design will allow the ue job to use semi-persistent resource assignments to send any support rate voice frames, and the mid-sixth-percentage resource assignments can be used for the most commonly used voice frame rate, the requested voice frame. Rate, etc. UE n6 may receive a non-persistent resource assignment from eNB 1 and may use the granted uplink resource for a predetermined duration, which may be sufficient to transmit - a frame of time may be after the duration of service (9) 123916 .doc -16- 200818826 For example, after the SID frame is sent, the uplink resources are granted. Ue m can receive from eNB 100

, ^ # + hold, sexual resource assignment, and as long as the UE transmits more data in the return time period. . . . , E 116 can retain the granted uplink source. The timeout period can be a solid-valued or configurable value and can be selected based on the inter-frame time. The inter-frame is ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The expected time between the two. For v〇Ip, ue 116 can transmit voice tons for 10 ms or 20 ms. The frame can be '' and the timeout period can be 40 ms to 80 ms. 〇UE 11.6 can use the chronograph ττρ 1 to maintain the timeout period. Tracking. 6 may be enabled after the first voice frame is sent using the granted uplink resource and the leaf timer may be restarted whenever a subsequent voice frame is sent. UE 11 6 may be the primary + beta main mountain. When the time delay expires, the granted uplink resources are discarded and are not used for transmission. If the granted uplink resource fails from 2 due to non-use during the timeout period, then the timeout period determines the amount of time that the granted uplink resource was not used after the end of the data dog. In order to efficiently utilize the available resources, if UE 116 is not intended to use the granted uplink key resources, UE 116 may develop a signal to waive the granted uplink resources before the timeout period expires. In a design, UE 116 may send as an in-band signal in the expected last data frame of the current data burst; ^Request. In another design, ...6, during an idle period = Beckham, the UE may (e.g., on the PUCCH) send a request without a body indication. This idle period can be longer than the frame but shorter than the timeout period. For example, if a voice frame is transmitted every 10 hearts or 2 〇ms, the idle period may be 30 ms, which is longer than the time interval between the two voice frames at 1239l 6.doc -17-200818826 The jitter of the arrival of the voice frame. The UE 116 may send a request without a data indication after the idle period has elapsed since the last transmitted data frame. If HARQ is employed, UE 116 may be granted - or multiple link resources on multiple HARq individuals. UE 116 may send an independent request without a data indication for each-assigned HARQ individual. Alternatively, ue m may send a single request with no data indication for all two assigned HARQ individuals. In any case, a request without a data indication can support the rapid de-allocation of resources ^ Accelerate the exchange of poor sources between UEs. $ Reduced transmission time, requests without data indication can be sent with lower modulation and coding and/or higher transmission: rate. t. The condolence terminates the semi-persistent resource assignment based on any of the following: no data is sent during the timeout period; an explicit signal is sent by the UE to terminate the resource assignment, • is sent by the eNB to terminate the resource assignment Clear signaling; and resource reassignment to another UE. Figure 4 shows an example of a semi-persistent and non-persistent resource assignment read. At the time of the]], the UE 116 has to be sent on the uplink key: language: data and transmits the time T12' eNB 1 for the uplink resource for the full rate frame. Sufficient box = semi-persistent resource assignment for link resources. At time T13, the UE 116 grants an uplink resource to transmit the first voice frame.仙ΐ6 立 / B M, Tl5 and T 】 6 transmission of additional voice frames ‘where each additional language frame is sent within the timeout ^ 1 Ume〇ut of the previous voice frame.

The time of the timeout period after your time τ16 is Tl7' semi-persistent resource assignment invalidation and service 116 abandons the granted uplink resources.

At time, UE 116 has a $out frame to be transmitted on the uplink and transmits a request for uplink resources for the SID frame. At time T22' eNB (10) returns a non-persistent resource assignment with sufficient uplink resources for the frame. At time τ23, UE 116 transmits the SID frame using the granted uplink resources. The non-persistent resource assignment expires after transmitting the SID frame, and the UE 116 abandons the granted uplink = at time TS1, the UE 116 has the voice material to be transmitted and transmits the uplink resource for the full rate frame. Request. At half time 32, 100, a semi-performing resource assignment with sufficient uplink resources for the full rate frame is returned. UE 116 transmits the first voice frame using the granted uplink resource at time T33 and transmits an additional voice frame at time Τη. The idle period after the time 乃 is not sent within the voice frame. At time η, which is the idle period after time T34, UE 116 transmits a request without a data indication to abandon the granted uplink resource. A semi-persistent resource assignment may indicate a particular resource that can be used to send data. The granted resources can be given by specific resource blocks in a particular subframe. Each of the lean blocks can cover a set of subcarriers in a particular duration (e.g., a subframe). If HARQ is used, the granted uplink resources can be used for one or more specific HRAQ individuals. A semi-persistent resource assignment can also indicate one or more specific MCSs that can be used to send data. Each Mcs can be associated with a special frame size, a specific coding scheme or code rate, a specific modulation scheme, and the like. In any case, both eNB 100 and UE 116 are aware of the resources and MCS available for transmitting data. In one design, UE 116 may use the granted uplink resources to transmit data on the uplink without transmitting any signaling to inform the eNB 100 of the transmission of the data. In this design, eNB 100 may attempt to decode the transmissions in each of its subframes received on the granted uplink resource, where the data may be transmitted by UE 116. The eNB 100 may perform blind decoding for each MCS that can be used by the ue 116 to transmit data. In another design, UE 116 may notify eNB 100 of the data frame to be transmitted and the MCS that may be used for the message frame. In this design, the eNB 100 may attempt to decode the transmission it received only when notified and further based on the MCS (if transmitted). Correct

In both designs, if the eNB 100 does not correctly decode the data frame of the UE 116 within the timeout period, the eNB may de-assign the granted uplink resource. If HARQ is used, eNB 100 may wait a little longer than the timeout period to consider a possible ACK/NAK error before de-assigning the granted uplink resources. In general, semi-persistent and non-persistent resource assignments can be used with or without HARQ. If HARQ is used, semi-persistent and non-persistent resource assignments can be defined to cover certain aspects of HARQ. In one minute

Give another assignment. For semi-persistent resource assignments, semi-persistent or non-persistent resource inputs' and subsequent retransmissions can be scheduled, HARQ termination statistics should be 123916.doc -20- 200818826 on average between the frames# Μ μ仏4 mt send information frame, then each material: v. For the burdock, the average number of HRAQ passes per 20 (10) rounds and negatives should be J 20 ms to prevent data aggregation in the data buffer. For resource assignments that only cover the first transmission of the hash frame, the HARQ termination statistics may be thinner than a mirrored transmission (e.g., 12 frames, transmission) to reduce the number of resource requests for data frame retransmissions. The number of HARQ^ and/or target HARQ terminations may be selected to achieve an effective = source utilization. The target HARQ termination may be selected based on inter-frame time, interval between HARQ: HARQ transmissions, resource assignment only covering the first transmission or covering all HARQ transmissions, and the like. The (10) and code bits to be transmitted may be selected; the maximum coding gain may be achieved for an average number of HARQ transmissions, which is determined by the target HARQ termination. The amount of data that can be sent in a harq individual can be determined by the target HARQ termination (which can send more data within the longer HARQ termination, and vice versa) and other factors. The number of ARQ individuals may be configurable and selected based on the total amount of data to be transmitted, the amount of data I transmitted on each HARQ individual, and the like. </ br> </ br> </ br> <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> For the downlink, whenever the eNB 1 〇〇 has to be sent to the certificate 116, the data ‘the eNB can just send the downlink key resource f to the eNB 1 on the PDCCH, when it has the voice frame to be sent A semi-persistent resource assignment is sent and a non-only 'birth source' assignment can be sent when it has a frame to be sent. A semi-persistent source assignment may be valid as long as more information is sent within the timeout period, and if the data is not sent within the timeout period, the semi-persistent resource assignment may be invalid. The same or different timeout periods are available for the downlink and uplink. The eNB 1 may also terminate the semi-persistent resource assignment before the timeout period by signaling to the UE 116. When no more data is sent to ^ 116, the downlink resources can therefore be quickly swapped. In a design, the eNB 100 may send a downlink grant at any time, and the UE 116 may monitor the PDCCH to determine if the downlink grant has been transmitted to the UE by φ. In another design, the eNB 1 may send downlink grants only in certain subframes (which may be referred to as receiving subframes). UE ii6 may monitor the PDCCH only during reception of the subframe to determine if the downlink grant has been sent to the UE. This design supports discontinuous reception (Drx) of UE 116. For the downlink, a semi-persistent resource assignment may indicate a particular downlink resource (e.g., a particular resource block and a particular subframe) to which data may be sent to the UE 116. The semi-persistent resource assignment may also indicate that one or more specific # MCSs may be sent on the downlink resource granted. The UE 116 may perform blind decoding on the transmissions received in each of the subframes (which the data may be sent to the UE in each subframe) based on the pre-configured MCS. Alternatively, eNB 100 may be used to transmit a profile signal to UE 116, and UE 116 may decode the transmission it received based on the MCS of the signaled signal. For the downlink, eNB 100 may send the information to UE 116 using Cell Radio Network Temporary Identification Pay (C-RNTI) or some other unique identifier assigned to UE 116. In this manner, the UE 116 can be allowed to clearly determine if it is the intended recipient of a given data frame. In one design, eNB 1 00 123916.doc -22- 200818826 may generate a cyclic redundancy check (CRC) of the data frame, then mask the CRC with the C-RNTI of the UE 116, and then attach the UE specific CRC to the data frame. The data frame and UE specific CRC are then sent to the UE 116. In another design, the eNB 1 may send the message frame to the UE U6ic-RNT] and then send the message to the Ue 116. For both the downlink and uplink, the eNB 1 may send a source assignment to the ue 116 using the C RNTUf of the UE 116. In this way, ue_116 can be allowed to clearly determine whether it is intended to be a recipient of a given resource assignment. In one design, the eNB's may generate a CRC carrying the message of the resource assignment of the UE 116, then mask the CRC with the C-RNTI of the UE 116, then append the UE-specific CRC to the message and then message and UE specific The CRC is sent to the UE 116. In another design, the eNB 100 may mask the message based on the UE 116iCRNT and subsequently transmit the masked message to the UE i 16. Resource assignments may also be sent in other ways such that (1) such assignments can be reliably received by the receiver ue and (ii) errors in the exchange of resources between UEs can be reduced. For both the downlink and uplink, eNB 1 may send a tone to replace the pending semi-persistent resource assignment. For example, in each subframe that is covered by a semi-persistent resource assignment, the eNB 100 may send a message indicating the resource and/or MCS for the *child frame, which may be different from the pre-configured resource - Source and MCS. UE 116 may operate based on pre-configured resources and MCS unless such parameters are replaced by messages from eNB 100. For the downlink, multiple UEs may have a common downlink key &gt; source assignment for downlink resources to monitor the identifiable binary transmissions sent by the eNB 100 to such UEs. The eNB 100 can be assigned a keyway at any given time 123916.doc -23- 200818826

The foreigner will transfer the bamboo to the UE. Such UEs may attempt to decode their transmissions received from the assigned downlink resources and may send 7 ACK/NAKs on the same uplink signaling resource associated with the downlink resources. Each UE can use an open key control (snap to send its ack or NAK to combat ACK/NAK collisions from different UEs. In a trick, ACK can be sent as] (or ', open&quot;) And the NAK can be sent as 〇 (or, closed). This design allows the eNB 1 to correctly detect the presence of the NAK sent by the non-receiver of the data transmission. The ACK transmitted by the receiver UE of the data transmission transmitted on the link resource. For the downlink, the UE 116 may be assigned a persistent resource assignment, and the data may be sent by the sUE 116 without using the control channel. The resource allocation may indicate the preconfigured downlink resources and MCS for the UE. The preconfigured downlink resources may include a limited set of downlink resources that the UE 116 may receive under the data. The preconfigured MCS may include A limited set of MCS that can be used to gross the data to the UE 116. The UE 11 can blindly decode the downlink transmission based on all possible combinations of preconfigured downlink poor resources and MCS. The eNB 100 can use the UEiC_RNTI to frame the data frame. Send to ue 116. This way you can allow υΕ 16 determines that the data frames are sent to the UE and may also allow other UEs to determine that the data frame is not intended for use in the other 1^1^116 and other 1; £ can use 00 feet to send the gossip ^/" The collision is attributed to the collision of common downlink resource assignments. Figure 5 shows the design of a process 5 (10) for exchanging data in a wireless communication system. Process 500 may be by a UE, a base station (e.g., an eNB), or some other The entity performs the resource assignment of the communication link, wherein the resource assignment is valid as long as more information is sent within the predetermined time period of the last 123916.doc -24-200818826 transmission of the data (block 512). The resource assignment may include resources. And one or more commission modulation and coding schemes usable for transmission of poor material via the communication link. The data may be exchanged (e.g., transmitted and/or received) via the communication link based on the resource assignment (block 5 14). The resource assignment is abandoned immediately after the decision is made that no more data has been exchanged within a predetermined time period since the last exchange was made by the sub-funds (block 516). Process 500 may be performed by the UE for data transmission on the uplink. .

The UE may (e.g., from the v〇Ip application) receive the information to be sent on the uplink, send a request for the resource in response to receiving the data to be transmitted, and receive the resource assignment in response to the request. The UE may then send the profile based on the resource assignment 'set the timer to a predetermined time period after transmitting the data, send more data when the resource assignment is available and the timer has not expired, reset the timer after sending more data and Abandoning a resource when the timer expires The UE may forward a request without a data indication to terminate the resource assignment before the timer expires. The UE may (1) together with the current data burst expectation last (four) or (ii) when no more material is sent during the special time period of the last data transmission or (in) based on some other conditions or trigger events, no data indication This request. Process 500 can also be performed by the base station for transmission on the uplink key. The base station may receive a request for resources from the UE and may send the resource fingers to the UE. The base station can speculate on the information transmitted by the uplink on the uplink based on the f-source assignment and the blind decoding of the received transmission. Process 500 can also be performed by the base station for transmission on the downlink key. The base station can receive the data to be sent to the UE on the downlink. 123916.doc -25- 200818826 Determine the resource assignment based on the received data and send the resource assignment to the UE. The base station can process the data based on the C-RNTI of the UE and can transmit the processed data to the UE on the downlink. Process 500 can also be performed by the UE for data transfer on the downlink. The UE can monitor the control channel to receive resource assignments. The UE can operate in DRX mode and can specify a time interval to monitor the control channel to receive resource assignments. The UE may perform blind decoding of the received transmissions based on the resource assignments to detect the data to be sent on the downlink. The UE may receive the data on the downlink based on the resource assignment and may use OOK to send an ACK or NAK to the received data. For both the downlink and uplink, the data can be sent in the data frame by HARQ. Each data frame may transmit at least one HARq transmission to transmit a HARQ transmission for the first transmission of the data frame and possibly additional HARQ transmission for the retransmission of the data frame. The expected number of HARQ transmissions per data frame may be shorter than the expected time interval between consecutive data frames to avoid aggregation of data buffers. If the resource assignment covers only the first HARq transmission for each data frame, then the expected number of harq transmissions for each data frame can be different? To reduce the signal transmission of retransmission. Figure 6 shows the design of a device 6 for exchanging data in a wireless communication system. Apparatus 600 includes means for determining a resource assignment for a communication link, wherein resource assignment is valid as long as more information is transmitted during a predetermined time period in which the data was last transmitted (block 612); for communication based on resource assignment The component of the exchange of data (module 614); and immediately after the determination that no more information has been exchanged within a predetermined time period since the last exchange of the material. 123916.doc • 26-200818826 Abandonment of resource assignment components (modules 616). Figure 7 shows a design of a process 7 for transmitting data on the uplink by U E. The UE may, for example, receive data to be transmitted on the uplink from the VoIP application (block 712), and may send a request for the resource in response to receiving the data to be transmitted (block 714). The UE may receive an uplink resource assignment, wherein the resource assignment is valid as long as the more information is sent within a predetermined time period in which the data was last transmitted (block 716). U E may send data on the uplink • based on resource assignment (block 718). The UE may send the data on the uplink. The timer is then set to a predetermined time period (block 72〇 ue may send more data on the uplink when the uplink is available and the timer has not expired (block 722) The UE may abandon the resource assignment when the timer expires (block 724). Figure 8 shows the design of the device 8 for transmitting data on the uplink. The device 800 includes, for example, a v〇Ip application. A component (module 812) that receives data to be sent on the uplink key at the sac; (a module 812) for transmitting a request for a resource in response to receiving the data to be sent (module 814); for receiving the uplink A component assigned by the resource, wherein only the data source assignment is valid within the silent time period in which the data was last sent (block 816); means for transmitting data on the uplink based on the resource assignment (module 818) ) 'A component that is used to set the timer to a pre-four-cycle period after transmitting data on the uplink (module coffee); used to transmit more on the uplink when the uplink is available and the timer has not expired (4) Component Module -" and means for abandoning resource assignments when the timer expires (module 824). . Shows the process for exchanging data in a wireless communication system. 9(10) 123916.doc -27. 200818826 Private_ may be performed by the UE, the base station, or some other entity. The semi-persistent resource assignment or non-consent of the communication link may be determined (the block is called as long as the last time the data is sent last time) The resource assignment can be valid. The semi-persistent resource assignment can be granted for a sudden burst of expected data to be sent over the communication link. The non-performance refusal can be valid at the scheduled (four) time or at a particular pass.

The data may be exchanged via the communication link based on semi-persistent resource assignments or non-persistent resource assignments (block 914). Process_ may be performed by the UE for data transmission on the uplink. The UE may, for example, receive data to be transmitted on the uplink from the ν〇Ιρ application and may send a request for a resource. Sin can receive a semi-persistent resource assignment when requested for a voice frame and can receive non-persistent =, lean, assignments when requesting a message frame. The UE may send the first codeword group on the control channel when requesting for the voice frame and may send the second codeword group on the control channel when requested for sm remaining. Process 900 can also be performed by a base station for data transmission on the uplink. The base station can receive the reading of resources from the UE. The base station can send a semi-persistent resource assignment to the ue when requesting for the voice hub and can send a non-persistent resource assignment to the ue when requesting for the SID frame. Process 900 can also be performed by a base station for data transmission on the downlink. The base station may send the semi-persistent resource assignment to the UE when there is a voice frame to be sent to the fairy and may send the non-persistent resource assignment to the UE when there is a frame to be sent. Process 900 may also be performed by the UE for data transmission on the downlink 123916.doc -28-200818826. The UE may monitor the control channel to receive a half-ready assignment or a non-persistent resource assignment of the down link. If the semi-persistent asset is determined in block 912, such as the source, the UE and the base station may exchange data as described in FIG. 5 above. If a non-persistent resource assignment is determined in block M2, the UE and the base station can exchange the bedding (e.g., SID frame) and can abandon the resource assignment immediately after the data exchange.
