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

SUMMARY 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). The wireless local area network 1 includes at least one access point (AP) 1 〇 2 associated with at least one WTRU 104. The access point 1〇2 blames the communication requirements of the feeding device and its associated wireless transmitting/receiving unit 104. The WTRU 104 transmits the upstream traffic to the access point H) 2, and the access WLAN 2 transmits the lower volume to the wireless transmission/acceptance. Yuan 1G4. In the independent basic service group (office), multiple wireless transmission and storage of mu-cafes - no need to be in the wireless local area network system, a wireless transmission / receiving unit

If there is a bet on the ship, there is a bet that needs to be sent. The solution is transmitted, the wireless transmission 7 receiving unit (10) receives and ί =^:? finds the face to turn (to the slave record as) its large power, such as the consumption of the Wei unit 104 equivalent yuan 1 〇 4 different from the brief. The first table describes the wireless transmission/reception single-state activity transmission if state and its average energy consumption in the various states. The average power consumption is 80%. The general description is that the system is transmitting a data 4 50% 201025890 Outbreak program interception The device actively listens for 30% of the standby devices ignoring the media, but is able to transmit, receive, and listen to 5% of the sleep devices in a short time range (usually < 10 microseconds). The time to change to another state is about > 1 millisecond is less than 0.1%.

The problem with the local area network 100 is that the WTRU 104 may === spend a lot of time just to discover that there are only a few or none of the messages currently being transmitted, and may be spent in the active (four) state for a lot of time in order to discover It is received (for example, demodulation or unwinding transmission/reception unit 104. FM ^ traditional power saving party test to reduce the material / Wei unit or total amount, increase or decrease _ send / receive singular in the life or sleep state The total amount of time in the middle. The automatic power-saving mode (APSD) defined in the dirty enemy mountain is the example. 节省 Saving mode (s_na) and non-scheduled automatic power section = in the scheduled automatic power saving mode , access _2 and wireless transmission fine connection unit has agreed to schedule the time of its data (four):::: early division: service interval with 102 schedule, benefit line, Γ,, door access Point time ___ other listening, receiving or decoding frames). So wireless: === 5 In 201025890, because the wireless transmission/valve element 104 can spend more time on sleep ^: and the shortcomings of the 'scheduled automatic power saving mode scheme—that is, the complex and lack of scheduling automatic power saving mode The solution is complicated because it pre-schedules, going, where both the access point 102 and the WTRU 102 must have the same strict time limit. For example, the WTRU 104 must: transmit/receive i jobs wireless έ also 排 schedule read another 'self-access point point of view, the efficiency of the spelling rate section scalability is low' because of scheduling When the number of automatic function wireless transmission/reception unit ig4 grows, the access must wait for the wireless H to send data to the wireless transmission/reception unit ι〇4, but the mode must be found, and the delay and delay variation may be higher. Power 卽 unit L can sleep from automatic = save mode 'wireless transmission / reception: single = the:: save: two: receive unit _ come: move: ==, 丨 10 can cause collision, because blood line Second = 疋 wireless communication / receiving early 兀 but not the ship. u private / private 1 〇 4 can be busy 201025890 in the new IEEE ancestor 1 In County towel, for enhanced output, call a variety of frames : ί : for example, media access control (MAC) mosquito data private (MPDU) two entities Layer (PHY) Protocol Data Unit (ppDU) aggregation, and entity symbol = ft burst. Since these mechanisms usually aggregate multi-frames, the new "New Year's Eve Receiver Aggregation (MRA) Multi-Poll (MMp) and Power Saving Aggregation Descriptor (PSAD) have been proposed to improve power saving performance. The basic information of the polling and power saving aggregation descriptors - the aggregation frame may be quite long, so that the wireless transmitting/receiving unit 1〇4 does not have the entire aggregated bet only to find that there is no (four) material, and the access point 1〇2 is sent first. - Multi-receive H-aggregation multi-polling or power-saving aggregation descriptor frame to describe which WTRUs are included in the subsequent aggregation frame. The access point 102f first sends a frame to preview the new one. The destination of the data sequence and the transmission of the shouting. The silk/receiving unit 104 of the training program can receive the data from the time-based ship of the Weihe (no notice). The wireless transmission without data in the new sequence The receiving unit 1〇4 can also save power by sleeping in the new data sequence.

The access point 102 sends a plurality of rounds of interrogation frames 3G2 to a wireless transmission/reception list (4) 4. The multiple two inquiry frame 302 includes uplink and downlink transmission schedules. After the short message, the access point 102 transmits the downlink data to the wireless transmission/reception of each recipient in the receiving offset and the m box 302. _ Display the transmission of the next message frame to the division of the lining _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Each WTRU/telephone TC104 transmits a transmission-offset via the transmission offset and transmission. The receiving offset is set by the completion of the transmission of the partial reference money (4). The fourth ugly - traditional power saving aggregation descriptor frame copper. The power saving aggregation descriptor frame 400 includes a frame control/period field 4〇2, a receiver address field 404, a (four) bit box overview, a basic service (10)_block 408, and a power saving aggregation. The descriptor parameter is 41 〇, a receiver information is placed, and the view is touched. The decoration of the money is reduced by the parameter boring. The description of f follows the power saving aggregation descriptor frame gamma after the power saving (PSA). _襕倾^ indicates all the periods described in the receiver information block 412 below the upload and upload opportunity (10) ps). The Power Save Aggregation Descriptor parameter 41 () includes the descriptor end field 416 during the power save aggregate access phase described in the Aggregation Descriptor Box 400. According to the IEEE 802.11 η Joint Proposal Specification and the Enhanced Wireless Alliance (EWC) specification, a Power Save Multi Poll (PSMP) feature has been imported. A power saving multi-round interrogation frame provides time scheduling for downlink (DLT) and upload (ULT) and is set by the power saving multi-polling transmitter and the power saving multi-polling receiver. Broadcast media access control management action frame. The scheduling time begins with the power saving multi-polling brewing. Downstream - by power saving

It is described in the multi-round interrogation box and is intended to be used by the power-saving multi-polling receiver for frame reception. The uploading system is described in the multi-round inquiry frame of the power casting province, and it is deliberately transmitted by the power saving multi-polling receiver for the frame transmission. ^5A to 5C show the power saving multi-round inquiry frame 5〇0, the power saving multi-round inquiry frame 5(8), the god saving township polling parameter setting field view and the identification saving multi-round inquiry frame 500 station A format of the information field 5〇4.

Figure 6 shows at least the configuration of this month - access to the Radisson at least - wireless transmission / receiving unit: = wireless communication (four) system _. The access point _ may be a wireless ship/receiver unit. The child access point (10) determines the transmit-sleep frame to at least - the wireless transmit/receive unit 62 () associated with the access point 610 according to certain criteria. ^ The sleep frame notification is in access, covering all or Some of the WTRUs 62 enter a sleep state (or a standby state 'hereafter referred to herein as "sleep state") for a certain period of time (eg, during sleep). Using the sleep frame, the access point 61 indicates all or some of its associated wireless transmit/receive units (4), and there is no drop in the sleep age: 1 will be sent by the access point 61〇 to the wireless transmit/receive unit (10) 'And wireless transmission 11 201025890

The receiving unit 620 can enter a sleep state during sleep.

The access point 61 (or a wireless transmit/receive unit) includes a measurement unit "a comparator 614 and a power save controller 616. The measurement unit 612 measures a predetermined parameter, which will be explained later herein. The comparator 614 compares the measured predetermined parameters with the threshold value. If the measured predetermined parameter exceeds the threshold value, that is, the wireless transmission/reception unit 620 enters a sleep state during the sleep period, the power saving controller 616 is configured. Sending a sleep frame to at least one wireless transmit/receive unit_. The wireless transmit/receive unit 620 includes a power save configured to receive a sleephead from the access point (10) and trigger a transmission to a sleep state during sleep. Control Fig. 7 is a flow chart of a processing routine for transmitting a sleep frame according to the present invention. An access point 610 measures a wireless medium inactivity time (e.g., when idle (step 7G2). The inactivity time may It is defined in many different ways. For example, the inactivity time may be defined as the time elapsed since the last frame was transmitted by the wireless medium. A bet is sent by the access point 61〇 or any of the wireless transmitting/receiving units 62 与其. Each time a new related frame is sent 'this inactivity time is reset, and the domain inactivity time is again Start.

Preferably, the access point 61G can wait for a minimum wake-up time before measuring the wireless medium inactivity time. The minimum wake-up coffee refers to a system in which the wireless transmitting/receiving unit can make the second inactive period of the inactive_wei wake-up. Access point 610 then determines if the measured inactivity time exceeds a predetermined value (step 704). If the measured inactivity time is :, the process is fined back to the division 02 to further measure the wireless medium miscellaneous ==. If the inactivity time exceeds the predetermined threshold, the access surface 0 sends a - sleep frame to at least - rogue send / receive element (four), the miscellaneous wire transmission / receiving single 12 201025890 yuan 620 can be indicated by the sleep frame Go to sleep 706) during sleep. Upon receipt of the Wei Wei's transmitter without the transfer/received G facet frame (step 7G8). Such verification may be performed by comparing the transmitter address (ta), the basic service identification code (BSSID) field, or any associated address field to the address of the access point 610. If the sleep frame is not transmitted from the access point 61G associated therewith, the 'wireless transmitting/receiving unit (10) does not go to sleep. If the transmitter of the sleep frame is connected to the wireless transmission/reception unit, the point 61G's the thread/touch unit 62() is in a sleep state (step 710). The access point 61A and the WTRU_wait until the end of the sleep period (step 712), and the processing procedure 7_ to the step is to measure the inactivity time at the end of the sleep period. During the sleep period, the WTRU 62 is preferably not permitted to ship &quot;to the access point 61&apos;. Alternatively, the choice of permission or non-permission in the sleep period 2 can be indicated by a specific field of the sleep frame towel. Another method is to permit the transfer of the upstream data to the access point (10) as a pre- (e.g., not necessarily indicated in the sleep frame). θ when the WTRU 258 is allowed to transmit during the sleep period, the upstream receiving unit 6 may request a certain _ response (eg, acknowledgment (ACK) or block acknowledgment (ΒΑ) ). In this example, even if the access point 61 does not support the flow to the WTRU 62 during sleep, the access point 61 can transmit the necessary _ (eg, a response or block response). To the WTRU, the access point 610 can send a sum (entrainment) in this response. The port 610 has data to the WTRU 62A. ', the wireless transmission/reception unit that initiates the uplink transmission during the sleep period. 13 201025890 3 may =^ to the access point (10) G) to the access point (10). The total amount of time available for the reverse agreement data unit. In such an example, 62 〇 and 6 different materials. In order to communicate via the transmission downlink to the wireless transmission/reception unit, the reverse is not allowed. Or, access point 61. It may be that during the sleep period, ί二π二二f may not send any frame or send—the frame indicates that the access point = 0 is lightly _ the amount of the subscription to the silk-like/touch unit (four) (for example, sleep __). In addition, the transponder/receiving unit 620 may not be allowed to transmit a signal of a reverse grant. ❿ 眠 眠 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ = point _ continuously measures the inactivity time.

The predetermined threshold value should be long enough to cover the competition window maximum (eg 〇3寮m 〇Wireless transmission contact unit coffee coffee (10)== ςsleep state. At the end of the sleep period, the exchange of the uplink and downlink frames continues to invent and the traditional automatic power saving mode, multi-receiver aggregation Polling, power saving aggregate descriptor or power saving multi-polling party _ main ship pre-scheduled for a specific time schedule.

However, other parameters may be considered for the mosquito. Other parameters include the shoe flow. Load 2 at the media usage measurement, at the access point or wireless transmission/reception single domain rush = quantity, quality of service parameters or number of wire and scale transmission/reception units, stream 1 set, wrong material ·, ( For example, transmission of wrong scales (legs), seal rate (PLR), number of retransmissions and retry attempts, delay and jitter measurements, configuration parameters, or the like. These measurements may be in a dependent state (AC) Whether and when mosquitoes are sent—the parameters of the sleep frame may not be secreted because of different _. For example, with inactive _ (or other parameters) threshold ' threshold may be based on other factors, measurement Or the situation, such as the flow of the load, the amount of movement, '4 can be touched. Similarly, the sleep program and the minimum time (if the sleep provides the county continued difficult _ no _ send / Wei unit sleep 2 and miscellaneous (10)). _ may refer to the sleep frame is defined as a dirty parameter such as 'sleep lying The face_box starts as soon as possible after the end of the box. Or, it can indicate the start time and period during sleep (or start time and knot reception, the identity of the line f up/receiving unit 62G may be _ indicating that all wireless transmission/sleeping should go to sleep The status of the broadcast address 'one' indicates some of the multicast addresses that should enter the sleep thief sputum transmission/reception unit 620 or a list of unicast bits that indicate the specific WTRUs that should enter, Or 201025890, the wireless transmit/receive unit 620 can be identified in a supplemental manner via the WTRU 620 that recognizes that it should not go to sleep. For example, the identity may be an address or a dummy address. To indicate that all WTRUs 620 should. Entering the sleep state (because only the wireless transmission with the address or the dummy address 接收 receiving unit 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 a list of unicast addresses to indicate that those wireless transmit/receive units 620 that are not in the address list should go to sleep. The sleep frame can optionally provide additional information 'eg, whether a wireless transmission ◎ / receiving unit 620 can send an indication of upstream traffic during sleep and a whether the wireless transmitting/receiving unit 620 should update its network allocation vector according to sleep period (NAV) instructions during the period. The sleep frame can be implemented using any existing frame or a new frame of any new frame, such as a control frame, management frame, data frame or motion frame. For example, the sleep frame can use a quality of service polling frame, a contention free (CF) polling frame, a power saving (ps) polling frame, a clear to send (CTS) frame, and a request for transmission. (RTS) frame, a multi-receiver aggregates multiple rounds of interrogation frames, a power saving aggregation descriptor frame or a power saving multi-round interrogation frame. 〇 A multi-receiver aggregation multi-round interrogation frame can be used to achieve the sleep frame function in accordance with the present invention. N station block 2〇8 (shown in Figure 2) can be set to '0' or the station block 2〇8 can be omitted to indicate that there is currently no new frame 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 field of the multi-receiver aggregation multi-round interrogation frame, and can be updated The network allocation vector for its period value. Alternatively, an interval of necessary intervals between the transmission of the multi-receiver multi-inquiry frame and the scheduling frame (or frame 16 201025890) can be imported to implement the sleep frame function month b. After the multi-receiver aggregates the transmission of multiple rounds of inquiries, the interval between subsequent uploads is usually - the short frame. Any interval longer than the frame interval is equivalent to the import of the sleep frame. - The access point transmits a multi-reception burst bet that is transmitted from a WTRU scheduling (e.g., polling) response for a long time after the multi-receiver aggregation multi-round interrogation frame is communicated. The multi-receive quiz polling box schedules one or more uplink frames in a manner that permits unnecessary idle time between the multi-received (four) multi-polling bet and the first-scheduled uplink frame. This is equivalent to a wireless transmission/reception sleep period that is independent of the multi-receiver aggregation of the multi-receiver. Alternatively, a dummy frame can be transmitted in a multi-receiver aggregation multi-poll sequence (e.g., invalid or quality of service invalidation frame) to a real or virtual WTRU. The dummy frame is a frame that is not used by any upper layer that receives the wireless Wei/receive unit. This virtual bet is only used as a method of no side secrets rather than making it a guarantee. If the real wireless transmission/reception single capture is used as the destination wireless Wei/subtract unit, those who do not need to transfer/subtract units are not in need of money and are very concerned about saving God as it is being threaded to receive dummy data. The dummy WTRU may be a wireless transmission of a dummy or fictitious Media Access Control (MAC) address that is not associated with an access point or with an address that does not correspond to any real WTRU associated with the access point. / Receive unit associated wireless transmit/receive unit. The imaginary section includes bribes—media access protection addresses that are not used in the access point area or that will not be used by any WTRU. The dummy wireless transmission/reception unit does not necessarily exist physically. This is equivalent to the sleep period of the wireless transmitting/receiving unit that is not related to the dummy frame. The power saving aggregate descriptor frame can also be used in accordance with the present invention to achieve a sleep frame. Shooting the reference to the money of this article (four) gather the poll and save 17 201025890, the solution _ can _ power save aggregation descriptor frame case. The power saving aggregation descriptor parameter field (shown in FIG. 4) may be set, or omitted, with an f-line transmission/reception list, 20 is concatenated in the power saving aggregation description 5 by sending a dummy frame (eg, a Efficient air box or a service quality invalid frame), or via scheduling (for example, polling), an in-between frame and a response, or an unused sleep period or multiple wireless between the number of responses Delayed response of the transmitting/receiving unit 620, when the sleep is extended by the use of fraudulent lie, network allocation to 4 periods and/or fields, and the length and ratio of the 802.11 η fine or legacy signal field, The following is an example: the access point 610 may effectively invalidate the sleep frame when the wireless media is idle and the effect is longer than the invalid or service quality during the fraudulent period of the real frame. Features. Savings When the multi-round interrogation frame is made into a sleep frame, the duration of the media access control header of the power/identity level or physical layer (set via the network allocation vector). Or the power section _ in Figure 5 can be used as a provincial multi-round interrogation indication by the power section which may be equivalent to the period during the power saving rim. The sleep period value. Alternatively, the increment specified in the shelf 508 during the conventional sequence may be _ ^ force rate, ie the number of bits in the h round scale column 508 may be permitted ==== large value (eg higher than 4 milliseconds) 'borrower , Gong (four) Qiqi and Gongzhu province. Or the strength of the sheep, that is, the minimum riding degree or fineness of the field 5〇8 during the 4th round of the round can be 18 201025890 can be added from the traditional grain to the drum value, which is expected to be a slave - the maximum sleep period of 4 milliseconds . For example, the axis is 〇 5 milliseconds or a fineness value, assuming 9 bits are used for the power saving multi-polling sequence during the shed 5 〇 / about 256 milliseconds and 512 milli_ _ _ _ _ _ _ _ _ _ combine it all toghther. / Even the fineness or resolution during sleep may be indicated dynamically. As with the implicit identity of the box's power township polling gambling, it may be possible to cause the receiving transmitting/receiving unit 620 to utilize other (higher) when calculating the block 508 (shown at the _) from the power multi-polling sequence. The value of the fineness. For example, because the sleep frame may be recognized as receiving - a power/rate saving multi-round interrogation frame that does not contain any upload or downlink entries (eg, receiving a power save multi-round interrogation frame that does not contain any work, It can be called a "(four)" power section ^ multi-round ^^^) 'When identifying this empty power saving multi-round interrogation frame, the wireless transmission/reception single TC620 is a power saving multi-polling sequence during the block 5〇8 uses a new fine sensitivity value (for example, when calculating sleep periods, the wireless transmit/receive unit gamma uses a higher degree of detail (eg, 1 millisecond) without using a fineness of 8 microseconds).

Or, a special field, a proportional field is included in the power saving multi-round inquiry (for example, in the power saving multi-polling parameter setting block 5〇2) to indicate the work f saves the multi-poll sequence period field The subtlety of 508. For example, the power saving multi-polling of the reserved bits in the parameter field can be caused by the wire to indicate whether it is higher in fineness or more sigma. Having a barrier _ gamma is a bit that requires less than &gt; to some maximum during the delivery period, rather than having to use more bits to increase the size of the field 5 〇 8 during the power saving multi-polling sequence. The proportional field can also use more than one bit 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 multi-round 3 or any other frame. ^丁控 19 201025890 The field in the field or HT signal field can be used to carry information about the sleep frame. The scale field can be used to scale or indicate any period field or any time-based blocker' such as period/identity block, block during spoofing, upload/downward start offset, upload/down period, or any The subtlety of the different levels of other fields without having to substantially increase the number of bits in such a field. In accordance with the present invention, access point 61 transmits a capability information block to indicate its ability to support power managed sleep frames. The capability information intercept indicates whether the access point 610 supports the sleep frame in accordance with the present invention, and if the sleep frame is supported, which frame is used as a sleep bet. Capability can be included in the beacon or exploration ❹ response box, or in the associated request or re-association request box. The lion slave power saving of the invention. This wealth can be used to improve the efficiency of wireless media by reducing media competition. By bringing certain wireless transmit/receive units into a sleep state while others remain awake, the number of awake no-transmit/receive units competing for the wireless medium becomes smaller and the output can be enhanced. ... can be applied based on the access level (AC) basis... the wireless transmitting/receiving unit with data in a certain access level enters the sleep state, and the same as ^^〇/^ 因因魏存财财(四) And awake (licensed to communicate and receive).
