Abstract

A method and system for reducing power consumption of a wireless transmit/receive unit (WTRU), (i.e., mobile station), are disclosed. A first WTRU measures a predetermined parameter and determines whether the measured predetermined parameter exceeds a threshold. If so, the first WTRU sends a sleep frame to a second WTRU. The sleep frame indicates sleep duration. The second WTRU receives the sleep frame and enters a sleep state for the sleep duration. The predetermined parameter may be an inactivity time of wireless medium. The second WTRU may or may not be allowed to send transmission to the first WTRU during the sleep duration. The sleep frame may be a control frame, a management frame, a data frame or an action frame. One of a multiple receiver aggregate (MRA) multi-poll frame, a power saving aggregation descriptor frame, or a power save multi-poll frame may be used as the sleep frame.

Description

200803219 IX. INSTRUCTIONS: FIELD OF THE INVENTION The present invention relates to a wireless communication system (e.g., a mobile station) including a plurality of wireless transmit/receive units (WTRUs). More particularly, the present invention relates to a method and system for reducing power consumption of a wireless transmit/receive unit. [Prior Art]

Figure 1 shows a traditional infrastructure mode wireless local area network (WLAN) iOO. The wireless local area network 1 includes at least one access point (Ap) 1〇2 associated with at least one of the wireless transmitting/receiving units 104. The access point 1〇2 is responsible for the communication requirements of the WTRU's associated wireless transmit/receive unit 1〇4. The WTRU 1 发送 4 transmits the upstream traffic to the access point 1 〇 2, and the access point 102 transmits the downstream traffic to the WTRU 1 〇 4. In an independent basic service group (IBSS), a plurality of wireless transmitting/receiving units ι〇4 directly talk to each other in a point-to-point manner without the presence of an access point 102. In the IEEE 802 J1 wireless local area network system, a WTRU 104 continuously (e.g., monitors) recorded media to determine if a frame is to be transmitted. If a frame is transmitted on the infinite media, the helmet receives the message (4) whether the frame (4) is in front (for example, the β疋 address is itself). Listening or receiving and decoding this frame consumes a considerable amount of power from the WTRU 1G4, such as = : the descriptor. Table 1 describes the ignorance of the wireless transmitting/receiving unit and its degree of energy consumption in various states. 200803219 State General Description Rough average power consumption (peak consumption = 100%) The active transmission device is in the process of transmitting a data burst 80% of the active receiving device is in the process of receiving a data burst 50% of the listening device activity detection Listening to the media 30% standby device ignores the media, but can transmit, receive, and listen for 5% of the sleep device in a very short time range (usually <10 microseconds) is essentially turned off, changing to another state The time is about > 1 millisecond is less than 0.1%. The problem with the conventional wireless local area network 100 is that the wireless transmitting/receiving unit 104 may be in a state of listening for a long time, only to find that there are only a few or no frames at present. It is transmitted over the wireless medium and may take a lot of time in the state of active reception, only to find that the frame it received (e.g., demodulated or decoded) is not traveling to the WTRU 104. Conventional power saving schemes attempt to reduce the amount of time that the WTRU 104 spends in an active reception or listening state and increase the amount of time that the wireless transmitting/receiving unit 104 spends in a standby or sleep state. An example of an automatic power saving mode (APSD) defined in IEEE 802.11e. 200803219 IEEE 802.11e defines Scheduled Automatic Power Save Mode (S-APSD) and Unscheduled Automatic Power Save Mode (U-APSD). In the scheduled automatic power save mode, the access point 102 and the WTRU 104 agree to schedule intervals in which the access point 102 will communicate data to the wireless transmit/receive unit 104. Since the wireless transmitting/receiving unit 104 and the access point 102 have agreed to schedule a specific time interval of the time of their data, except for the service interval in which they agree to the scheduled time of the access point 102, the wireless transmission/reception unit 104 The sleep state can be entered at all other times (e.g., the WTRU 104 does not listen, receive, or decode the frame). This provides a high power saving for the WTRU 104 because the WTRU 104 can spend more time in a sleep or standby state. However, one of the shortcomings of the scheduled automatic power save mode scheme is that it is complex and inelastic. The scheduled automatic power save mode scheme is complex because of its pre-scheduled nature, where both access point 102 and WTRU ® 104 must agree and achieve tight time constraints. For example, the wireless transmit/receive unit 104 must wake up at a strict time and the access point 102 must schedule the data for the wireless transmit/receive unit 104 within this strict time. In addition, the efficiency of the scalability of the scheduled automatic power saving mode scheme is low from the point of view of the access point, since the scheduled automatic power saving mode scheme must be stored, the point 102 and each wireless transmitting/receiving unit 104 Agreed schedule interval. As the number of wireless transmit/receive units 104 grows, the memory requirements of the access point 102 also grow. In addition, because the access point 102 cannot send data to the WTRU 200803219 104 every time there is media available, it must wait for the scheduling interval of the WTRU when using the scheduled automatic power save mode scheme. Delays and delay variations may be more south. On the other hand, in the non-scheduled automatic power saving mode, the WTRU 104 can sleep and wake up by itself to send a trigger frame to the access point 102. In response to the triggering of the frame, the access point 102 may send data to the WTRU 104. A disadvantage of the non-scheduled automatic power save mode is that when the WTRU 104 wakes up to transmit a trigger frame, it actually consumes more power because the active transmit state consumes more power. In addition, the non-scheduled automatic power save mode scheme may potentially waste wireless media because the access point 102 is responsive to the trigger frame and no data may be sent to the WTRU 104. Another problem with the non-scheduled automatic power saving mode scheme is that the WTRU 104 may cause a collision because the WTRU 104 may be unfunded by the busy channel. In the new IEEE 802.11n standard, to enhance the output, to import a variety of frame aggregation mechanisms, such as media access control (MAC) protocol data unit (MPDU) aggregation, physical layer (PHY) protocol data unit (PPDU) aggregation, And the physical layer agreement data unit data burst. Since these mechanisms typically aggregate multiframes, new mechanisms such as Multi-Receiver Aggregation (MRA) Multi-Polling (MMP) and Power Saving Aggregation Descriptor (PSAD) have been proposed to improve power saving performance. The basic idea based on multi-receiver aggregation multi-polling and power-saving aggregation descriptors is that since a aggregation frame may be quite long, the wireless transmission/connection 200803219 receiving unit l〇4 receives the entire aggregation frame only for discovery. Instead of having the right secondary access point 1〇2, the first one is sent—the multi-receiver aggregates the multi-polling six-rate section, and the descriptor descriptor frame is aggregated to describe which wireless transmitting/receiving units (10) are included in the subsequent aggregation frame. in. The access point withdraws the destination and delivery time of the data sequence that first sends the binary. Yu Xinjin: ', the poor wireless transmission/reception unit 104 can sleep and only subscribe to the private announcements. In the new sequence: wireless transmission/reception with no data, single magic G4, can also save power by sleeping in the new data sequence. Figure 2 shows a conventional multi-receiver aggregation multi-round interrogation frame 200. The multi-receiver aggregation multi-round interrogation frame 200 is used to define multiple response periods along with multi-receiver aggregation. The multi-receiver aggregation multi-round interrogation frame 200 includes a frame control/period field 2〇2, a receiver address block 2〇4, a_transmitter address block 206, an N station field 208, Receiver information block 21〇_ and Cyclic Redundancy Code Detection (CRC) field 212. The N station field 2〇8 indicates the number of receivers whose media access control protocol data unit is included in the multi-receiver aggregation master. Receiver information intercept 210 indicates each of the receiver addresses in the aggregate of the multiple receivers. Each receiver information block 210 includes a receive offset block 214, a receive period block 216, a transmit offset block 218, and a transmit period block 220. The Receive Offset field 214 defines the beginning of the first symbol of the downstream data containing the WTRU's downlink data associated with the load multi-receiver aggregate multi-polling. Field 216 during reception defines the length of the downlink data. The Transfer Offset field 218 defines the time when the transmission by this WTRU can be opened from 200803219. The transfer period 220 defines the limit during the transfer. Figure 3 shows a conventional procedure for multi-receiver aggregation multi-round interrogation frame exchange between access point 102 and complex WTRU 104. The access point 102 sends a multi-receiver aggregate multi-round interrogation frame 302 to the wireless transmit/receive unit 104. The multi-receiver aggregation multi-round interrogation frame 302 includes upstream and downstream transmission schedules. After a short frame interval (SIFS), the access point 102 transmits the downlink data to the receiving period of the wireless transmitting/receiving unit 104 of each of the receivers in the multi-round interrogation by the receiving offset and the multi-receiver The scheduled wireless transmission/reception unit 1〇4. Figure 3 shows the transmission of the downstream airframe to the five radio transmission/reception units i〇4 transmitted to the two receiver receiver blocks 304, 306 separated by the short frame intervals. Each of the wireless transmission/reception units 104 transmits an uplink transmission during the transmission period via the transmission offset and the transmission period. The receive offset and transmit offset are set with reference to completion of the transfer of the multi-receiver aggregate multi-round interrogation 302. Figure 4 shows a conventional power save aggregation descriptor frame 400. The power saving aggregation descriptor frame 400 includes a frame control/period field 4〇2, a receiver address block 404, a transmitter address field 4〇6, and a basic service identifier (BSSID). Field 408, a power save aggregate descriptor parameter placer 410, a receive information block 412, and a cyclic redundancy code check shed. The power saving aggregate descriptor parameter block 41 is used to converge the power save aggregation (like) access phase (PAP) following the Ik power, ie, the provincial aggregate descriptor frame. During the period _ move all the quotations are received during the entire period of reception and upload opportunities (TX 〇ps) in the poor position 412. The power save aggregate descriptor parameter block 41 includes a descriptor end block 416 indicating the period of the power save aggregate access phase described by the work 200803219 rate savings aggregate descriptor frame 400. A Power Save Multi-Poll (PSMp) feature has been introduced according to the IEEE 802·1 In Joint Proposal Specification and the Enhanced Wireless Alliance (EWC) specification. One power saving multi-round interrogation frame provides time scheduling for downlink (DLT) and upload (ULT) and multi-polling transmitter and power by power saving _ saving destination address setting used by multi-polling receiver To the media access control management action frame of the broadcast. The scheduling time begins with the transmission of the power saving multi-polling frame. The downlink is described by the power saving multi-round interrogation frame, and is deliberately used by the power saving multi-polling receiver for the frame reception period. The uploading system is described by the power saving multi-round interrogation frame, and is intentionally transmitted by the power saving multi-polling receiver for the frame transmission period. Figures 5A to 5C show power saving multi-round interrogation frame 5〇〇, power section_savings=inquiry box 5〇〇 power saving multi-polling parameter setting block 5〇2 and power saving multi-polling A format of the workstation information field of the frame 500 is 5〇4. Power saving multi-polling parameter setting block 5〇2 includes ^ workstation shed 506 and one power, that is, multiple polling sequence period, field 5 〇 8dN workstation block 5 〇 6 refers to the number of workstations that are not existing. Power Saving Multiple Polling Sequence Period Block 5〇8 indicates the current power saving multi-polling exchange period described by the power saving multi-round interrogation frame associated with the power saving multi-round interrogation frame. Each workstation information block 504 includes a _ downlink start offset field 51 (), a download period stop 512, an upload start offset block 514, and an upload period block 516 for scheduled transfer and upload. 12 200803219 Multi-receiver aggregate multi-polling, power-saving aggregation descriptor and power-saving multi-polling scheme are basically based on the media to pre-identify which wireless transmission/reception unit or wireless transmission/reception unit group is targeted by the new transmission. The group, while the wireless transmitting/receiving unit 104 unnecessarily spends most of the time in the active receiving state, turns/changes to the time spent in the sleep or standby state to achieve its power saving. The disadvantage of multi-receiver aggregate multi-polling, power-saving aggregation descriptors, and power-saving multi-polling schemes is that some form of pre-scheduling is required, albeit with a smaller schedule than the IEEE 802.lie automatic power save mode. The ratio is shorter with a shorter period. Multi-receiver aggregation multi-polling, power-saving aggregation descriptors, and power-saving multi-round interrogation frames also have a lot of added control information, so it is not very efficient to use wireless media. Multi-receiver aggregation multi-polling, power-saving aggregation descriptors, and power-saving multi-polling schemes provide power savings only when the frame is being transmitted, and do not provide power savings when the wireless medium is idle. SUMMARY OF THE INVENTION The present invention is directed to a method and system for reducing power consumption of a wireless transmit/receive unit. A first WTRU measures a predetermined parameter and determines whether the measured predetermined parameter exceeds a threshold. If so, the first WTRU transmits a sleep frame to the second WTRU. The sleep frame indicates during sleep. The second WTRU receives the sleep frame and enters a sleep state during the sleep. The predetermined parameter may be the inactivity time of the wireless medium. The first WTRU may wait for a minimum wait time before measuring the predetermined parameters. The 13th 200803219 two-line transmission/reception unit may or may not be allowed to transmit during sleep-transmission to the first WTRU. The sleep frame may be a control frame, a management frame, a data frame or an action frame. One of the multi-input multi-round interrogation frame, the power saving aggregation descriptor frame, and the power saving multi-round interrogation frame may be used as the sleep frame.

Hereinafter, the present invention will be explained with reference to a infrastructure mode wireless local area network including an access point and a wireless transmission/reception unit. However, it should be noted that the present invention is applicable to any wireless communication system including, but not limited to, a point-to-point mode wireless local area network, a wireless local area network mesh network, a global microwave access network, or a cellular mobile communication network. Roads, such as wideband code division multiple access (WCDMA), code division multiple access 2〇〇〇, global mobile communication system (UMTS) long-term evolution (lte), high-speed downlink packet access (HSDPA), high-speed downlink packet access Evolution, High Speed Uplink Packet Access (HSUPA), High Speed Uplink Packet Access Evolution, or similar 14 200803219. The present invention introduces a sleep frame for reducing power consumption of a wireless transmitting/receiving unit and for more efficient use of a wireless medium. Figure 6 shows a wireless communication system 600 including at least one access point 610 and at least one wireless transmit/receive unit 620 configured in accordance with the present invention. Access point 610 may be a wireless transmit/receive unit. Access point 610 determines to transmit a sleep frame to at least one wireless transmit/receive 10 unit 620 associated with access point 610 in accordance with certain criteria. The sleep frame informs all or some of the WTRUs 620 within the coverage of the access point 610 to enter a sleep state (or a standby state, hereinafter collectively referred to herein as a "sleep state") for a certain period of time (eg, during sleep) ). Using the sleep frame, access point 610 indicates all or some of the wireless transmit/receive units 620 associated therewith that no traffic is sent by the access point 610 to the wireless transmit/receive unit 620 during sleep and wirelessly transmitted The receiving unit 620 can enter a sleep state during sleep. The ® access point 610 (or a wireless transmit/receive unit) includes a measurement unit 612, a comparator 614, and a power save controller 616. Measurement unit 612 measures a predetermined parameter, which will be explained later herein. Comparator 614 compares the measured predetermined parameters and threshold values. If the measured predetermined parameter exceeds the threshold, that is, by the wireless transmitting/receiving unit 620 entering the sleep state during the sleep period, the power saving controller 616 is configured to send a sleep frame to the at least one wireless transmitting/receiving unit. 620. The wireless transmit/receive unit 620 includes a power save controller 15 200803219 622 that is configured to receive a sleep frame from the access point 610 and trigger a transmission to a sleep state during sleep. Figure 7 is a flow diagram of a process 700 for transmitting a sleep frame in accordance with the present invention. An access point 610 measures a wireless medium inactivity time (e.g., idle time) (step 702). This inactivity time may be defined in many different ways. For example, the inactivity time may be defined as the time elapsed since the last time the relevant frame was transmitted by the wireless medium. The associated frame is a frame transmitted by one of the access points 610 or any of its associated wireless transmit/receive units 620. Each time a new related frame is sent, the inactivity time is reset and the inactivity time begins again. Preferably, access point 610 can wait for a minimum wake up time before measuring the wireless media inactivity time. The minimum wake-up time refers to a period of time that is specified in the system to enable the WTRU to wake up before the access point 610 measures the inactivity time. Access point 610 then determines if the measured inactivity time exceeds a predetermined threshold (step 704). If the measured inactivity time does not exceed the predetermined threshold, the process 700 returns to step 702 to further measure the wireless media inactivity time. If the inactivity time exceeds the predetermined threshold, the access point 610 sends a sleep frame to the at least one wireless transmit/receive unit 620 to indicate that the wireless transmit/receive unit 620 can be within the sleep period indicated by the sleep frame. Entering a sleep state (step 706). Upon receipt of the sleep frame, the wireless transmit/receive unit 620 verifies the transmitter of the sleep frame (step 708). Such verification may be performed by comparing the Transmitter Address (ΤΑ) Block, the Basic Service Identifier (BSSID) field, or any associated address block to the address of the access point 610. If the sleep 16 200803219, the sleep frame is not in a sleep state from the access unit 620 associated therewith. Point 610 transmission, wireless transmission/reception OFF == transmitter system - and wireless transmission/reception unit supplementary frame: 〇 'The wireless transmission/reception unit 620 is based on sleep signal

Then wait until the end of the sleep period (step paws), and the process 70 returns to the step inactivity time. (4) Measurement when sleep is finished ^ During the sleep period, the wireless transmitting/receiving unit (10) is preferably not ▲ 午 ud up to the access point 61G. Alternatively, the selection of the permission or the transmission of the uplink data during the sleep period may be selected by the 4-inch fixed field in the sleep frame. The other method is to permit the transmission of the uplink data to the access point _ as a preset value. (For example, it is not necessary to indicate in the sleep message box). The gamma unit (10) is permitted to transmit the upstream traffic to the access point 610 during sleep, and certain frames of the WTRU 62 may require a response from the access point 610 (eg, with an acknowledgement (ACK) or Block response (BA) form). In this example, even if the access point 61 does not support starting downstream traffic during the sleep period to the WTRU 620, the access point 610 can transmit the necessary downlink response (eg, a response or block response) to The wireless transmitting/receiving unit 62 is. In addition, the access point 610 can send a sum (entrainment) in this response as long as the access point wo has the data to the WTRU 62 。.

In such an example, access point 610 can respond to the reverse grant via transmit downlink = to wireless transmit/receive unit 620. Or °, the access point 61G may ignore the reverse permission during the sleep period, and may not send any frame or send a frame indicating that the access point 610 is at this time and = 1 intends to transmit downstream traffic to the wireless transmission. / receiving unit 62G (eg, during sleep time). In another example, the WTRU 620 may not be permitted to transmit a reverse-permitted signal during sleep. Sleep may be similar to a transmission opportunity limit (e.g., 5 milliseconds), but may sometimes be different depending on other conditions, such as traffic load measurement or quality of service (Q〇S) requirements. Figure 8 shows an exemplary processing procedure for frame exchange in accordance with the present invention. A downlink frame 802 and uplink frames 804, 806 are exchanged between the wireless transmit/receive unit 620 and the access point. After the transmission of the uplink frame 8〇6, the media medium becomes inactive. The access point 61 〇 continuously measures the inactivity time. When the inactivity time exceeds a predetermined threshold, the access point 61 sends a sleep frame 808. The predetermined threshold should be long enough to cover the competition window maximum (e.g., 0 J milliseconds). The sleep frame 808 informs the wireless transmitting/receiving unit 620 that they can enter a sleep state during a sleep period (e.g., 5 milliseconds). At the end of the sleep period, the exchange of the upstream and downstream frames continues. The present invention and the conventional automatic power saving mode, multi-receiver aggregate multi-polling, power saving aggregation plug-in or power saving multi-polling scheme main area 18 200803219, the access point does not have to be pre-allocated a specific time schedule for wake-up . Thus, the point 610 stores the access point indicating the necessity of each wireless transmitting/receiving unit sword, and also liberates the wireless transmitting/receiving unit (10) instead of the automatic power saving mode, the multi-receiver aggregation multi-polling, and the power section. Descriptor or power saving multi-polling compatibility for wireless transmission/reception early power savings. In the case of the shirt, the domain wartime is determined by the decision of the developed radio frame. Other parameters may be considered for this decision. Other parameters: line in traffic load measurement, media usage measurement, access point or ς,, receiving early subtraction area (10) total data, number of service wireless transmission/reception units and their flow setting rights, error rate Cao For example, transmission error rate (grandfather), packet loss rate (PLR), number of objects, delay and jitter measurement, configuration parameters, or similarity = 乍 can be = whether and when to send - parameters of the sleep frame Because I am not willing to be different from me. For example, with the inactivity time (or the emotional threshold 2, the threshold may be dynamically adjusted based on other factors, measurement period such as flow load measurement. Similarly, sleep ♦: two small wake-up time (if used) sometimes It may also be dynamically adjustable based on other ', /, ' or conditions, such as traffic load measurements. The sleep frame provides a wireless transmit/receive unit that should go to sleep. 200803219::: Identity (then. During sleep, the sleep frame may be determined. For example, during sleep, it can be done after the end of the sleep frame: = The sleep frame can indicate the start time and period (or start time and end time) during sleep.

For example, the identity may be an address or an address to indicate that all of the WTRUs are awake~, (the port is ', has a WTRU with a null or a dummy address 620) Should not sleep). The identity may be a group of broadcast addresses to indicate that those wireless transmit/receive units 62 that are not part of the multicast address should go to sleep. The identity may be that the -column unicast address indicates that the wireless transmitting/receiving unit 620 that does not belong to the address column should go to sleep. The sleep frame can optionally provide additional information, such as an indication of whether the WTRU 620 can send upstream traffic during sleep and whether the WTRU 620 should update its network allocation vector during sleep ( Instructions during the NAV) period. The sleep frame can be implemented using any of the existing frames or new frames of any new frame, such as a control frame, management frame, data frame or motion frame. For example, the sleep frame can use a service quality rim 20 200803219 frame, a contention free (CF) polling frame, a power saving (?8) polling frame, a clear to send (CTS) frame, A request for transmission (RTS) frame, a multi-receiver aggregation multi-round interrogation frame, a power saving aggregation descriptor frame or a power saving multi-round interrogation frame. A multi-receiver aggregation multi-round interrogation frame can be used to achieve the sleep frame function in accordance with the present invention. The N workstation intercept 208 (shown in Figure 2) can be set to Ό' or the workstation field 208 can be omitted to indicate that there is no new WTRU sequence for the WTRU. After receiving the multi-receiver aggregation multi-round interrogation frame, the WTRU enters a sleep state during the sleep period indicated by the period value in the period of the multi-receiver aggregation of the multi-round interrogation frame, and can be updated The network allocation vector for its period value. Alternatively, an interval that is longer than the interval between the multi-receiver aggregation multi-round interrogation frame and the transmission of the scheduling frame (or frame response) can be imported to implement the sleep frame function. After the multi-receiver aggregates the transmission of multiple rounds of interrogation frames, the time interval between subsequent uploads is usually a short frame interval. Any longer than the interval of the short frame interval is equivalent to the introduction of the sleep frame. An access point is transmitted for a long time after a multi-receiver aggregation multi-round interrogation frame is transmitted, and a multi-receiver that transmits a response from a WTRU scheduling (e.g., polling) is aggregated into a plurality of rounds of interrogation frames. The multi-receiver aggregation multi-round interrogation frame schedules one or more uplink frames in a manner that allows for an unnecessary idle inter-frame between the multi-receiver aggregation multi-round interrogation frame and the first scheduled uplink frame. . This is equivalent to the introduction of a sleep period for the wireless transmit/receive unit that is independent of the multi-receiver aggregation of multiple rounds of interrogation frames. Alternatively, a dummy frame can be transmitted in a multi-receiver aggregation multi-polling sequence (e.g., invalid or quality of service invalidation frame) to a real or virtual wireless transmission/reception unit. The dummy frame is a frame that is useless for any upper layer that receives the WTRU. This dummy frame is only used as a method of occupying wireless media rather than leaving it idle. If the real WTRU is used as the destination WTRU, those WTRUs obviously do not need or are very concerned about saving power as much as they are manufactured to receive the phantom data. The dummy wireless® transmit/receive unit may be a wireless device that is not associated with an access point or a virtual or fictitious media access control (MAC) address that does not correspond to any real wireless transmit/receive unit associated with the access point. A wireless transmission/reception unit associated with the transmitting/receiving unit. The dummy frame may include only a media access control address that is not used within the access point area or that will not be used by any WTRU. The dummy WTRU does not necessarily exist physically. This is equivalent to the sleep period of the wireless transmitting/receiving unit that is not associated with the dummy frame. The power saving aggregate descriptor frame can also be used in accordance with the present invention to achieve a sleep frame function. All of the solutions described above with reference to the multi-receiver aggregation multi-polling in this article can be applied to the Power Saver Descriptor Frame case. The power save aggregate descriptor parameter block 410 (shown in Figure 4) can be set or omitted to indicate that no WTRU/receiver 620 is described in the power save aggregation descriptor frame. Or by sending a dummy frame (such as an invalid frame or a quality of service invalid frame), or via scheduling (such as polling), having some insertion between the power saving aggregation descriptor frame and the response, or A delayed response from one or more WTRUs 620 of unused unused time 22 200803219 between the number of responses, which may be imported during sleep. Sleep may be indicated via the use of a bullying period, a network allocation vector period, and/or via the length and ratio fields using an IEEE 802.11n signal field or a legacy signal field. The following is an example: the access point 610 may send an invalid or service quality invalid data frame with a period of fraud longer than the actual frame period when the wireless medium is idle, to effectively achieve the sleep frame function. When a power saving multi-round interrogation frame is used as a sleep frame, the power saves the period of the media access control header of the multi-round interrogation frame/identity field or the period of the physical layer convergence agreement signal field ( For example, the spoofing period of the legacy signal field or the semaphore period is used to control the period during which the uploading by the WTRU 620 is allowed (via the network allocation vector setting). Alternatively, the power save multi-poll sequence period block 508 (shown in Figure 5) can be used as indicating the sleep period. The Power ® Save Multiple Polling Sequence Period field 508 indicates the current power saving multi-polling exchange period described by the Power Save Multi-Rate Interrogation Frame. This sleep period may be equivalent to the value indicated in block 508 during the power save multiple polling sequence. Alternatively, the number of bits in block 508 during a conventional power saving multiple polling sequence may increase to permit a higher maximum during a sleep period (eg, above 4 milliseconds), thereby permitting longer sleep periods and more efficient Sleep behavior and power savings. Alternatively, the minimum resolution or fineness of the field 508 during the power saving multi-polling sequence may increase from the conventional 8 microseconds to a larger value, which would allow for a maximum of 23 of 200803219 that is greater than the current maximum sleep period of 4 milliseconds. Large values such as 'red by the use of 〇·5 亳 or 1 millisecond of the fineness value, false 疋 9 兀 used for the continuation of the multi-poll sequence during the delivery, about 512 with a maximum sleep period of 512 milliseconds Can be reached separately. - or more 岫 variables can be combined together ^ The fineness or resolution during sleep may be indicated dynamically. As the sleep frame ^ power saves the hidden identifier of the multi-round interrogation frame, it may be used in the calculation, the force rate saving, and the position transmission (receiving in the map), the problem transmitting/receiving unit - using it record. For example, because the sleep frame may be recognized as receiving a packet: Γ: power transmission or multi-round inquiry frame for the earth pass or the downlink entry (eg receiving stick, dragon 3 any workstation tribute block 5G4 power saving # The polling signaled that this is an "empty" power saving multi-round inquiry frame.

Fineness). In the special section of the inquiring pivot, a proportional block is included in the power saving multiple rounds (for example, in the power saving multi-polling parameter setting block 502), so that the day τ κ 功 志 即 即 即 轮 轮 轮 sequence The fineness of the block 508 during the period. For example, one of the reserved bits in the parameter column of the Thai ^ ^ 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以 可以Low detail should be used. The advantage of having a maximum j-block is that it requires fewer bits in a certain sequence of polls during the round, rather than having to use more bits to increase the size of the power-saving multi-round block 508. Proportional blockers can also use more than one 24 200803219 兀= to define more than two periods of detail (for example, two bits may be used to communicate up to 4 layers of detail). The proportional field can be included anywhere in the header or body of the power save multiple rounds of inquiries or any other frame. Fields within the HT^Manage field or jjt signal block can be used to carry information about the sleep frame. The proportional field can be used to scale or indicate any period field or any time-based field, such as period/identity block, block during spoofing, upload/downward start offset, upload/down pass, or The fineness of the different classes of any other interception without having to substantially increase the number of bits within such a block. In accordance with the present invention, access point 610 sends a capability information field to indicate its ability to support power management sleep frames. The capability information interception indication indicates whether the access point 610 supports the sleep frame according to the present invention, and if the sleep frame is supported, which frame is used as the sleep frame. The capability information block may be included in the beacon or discovery response frame, or in the associated request or re-request request frame. Ben Sheming was used to achieve the power of Lang province. The invention can also be used to improve the efficiency of wireless media by reducing media competition. By bringing certain wireless transmitting/receiving units into a sleep state while others remain awake, the number of awake wireless transmitting/receiving units competing for the wireless medium becomes smaller and the output can be enhanced. This can be applied based on an access level (AC) basis. A wireless transmitting/receiving unit having data in some access levels enters a sleep state, and the wireless transmitting/receiving unit may be awake (licensed for transmission and reception) due to data in other access levels. The sleep frame can be used because of 25 200803219 interference or noise measurements (such as quiet [Embodiment] ^ 独(游)). 】 A method for reducing the wireless communication system mk/receiving early % power consumption in a multi-wireless wireless transmission system.
