Wherein, duration ID and the corresponding relationship of wake-up duration (duration occurrence) can be preset to obtain, so that AP can Wake up according to the corresponding relationship instruction of duration, STA can determine the wake-up duration of each STA according to the corresponding relationship.Than It such as presets to obtain the corresponding 5ms of duration ID 0,1 corresponding 10ms, then when STA (such as STA1 or STA2) can determine the wake-up of STA1 A length of 10ms when the wake-up of a length of 5ms, STA2.To which each STA can determine respective wake-up according to the duration that duration ID is indicated Duration, i.e. PCR open duration, indicate the digit needed to save duration, reduce the corresponding data volume of duration in wake-up association, reduce Expense.

Optionally, the frame format of the wake-up association can be preset to obtain, for example, may include frame type (such as Frame Type), Wake operation mode (such as WakeUp Operation Mode, WOM), sender ID (such as Transmitter ID, TXID), its His information (such as Other Info), multi-user wake up information (such as Multi User WU Info), Frame Check Sequence (such as frame Check sequence, FCS) etc. one or more fields in fields, or can also include other fields, the application is not It limits.Further alternative, this, which initially retains the scheduling informations such as duration and the wake-up duration of each STA, can be carried on Multi In User WU Info field.For example, may include initially retaining duration (such as shown in Fig. 6 a to Fig. 6 f, in the wake-up association Initial Reserve Time) domain.Further, as shown in Figure 6 a, wake-up association can indicate each quilt by the STA listing field The wakeup time of the STA of wake-up is such as identified as a length of Time 1 when the wake-up of the STA1 of AID_0 (or WID_0), is identified as AID_ A length of Time 2 when the wake-up of the STA2 of 1 (or WID_1) first wakes up STA1 (AID_0), then wakes up STA2 (AID_1)；Such as Fig. 6 b Shown, wake-up association can indicate the STA being waken up by the STA listing field, and by waking up duration domain such as slot length Slot Length (such as can be the corresponding chronomere of wake-up duration of each STA, a STA ID occurs in STA list, corresponding to call out Awake duration then increases the chronomere) wakeup time of STA that is waken up of instruction then marks if Slot Length is 2ms Know be AID_0 (or WID_0) (in STA list occur primary) STA1 wake-up when a length of 2ms, be identified as AID_1 (or WID_ 1) a length of 2ms when the wake-up of the STA2 (occurred in STA list primary), and STA1 (AID_0) can be first waken up, then wake up STA2 (AID_1)；As fig. 6 c, wake-up association can indicate the STA being waken up by the MWID (or GID), and by waking up duration domain Such as the wakeup time for the STA that Time List instruction is each waken up, the wake-up duration for the STA being such as waken up is respectively Time 1, Time 2, wake-up sequence is indicated by the MWID, for example the sequence of STA corresponding with MWID is identical；As shown in fig 6d, wake-up association can The STA being waken up, and the wakeup time for the STA being waken up by Slot Length instruction are indicated by MWID (or GID)；Such as Shown in Fig. 6 e, wake-up association can indicate the STA being waken up, such as the corresponding STA of MWID by the MWID (or GID) and message bit pattern The STA that Bitmap information is 1 is the STA being waken up, and the wakeup time for the STA being waken up can be indicated by Slot Length； As shown in Figure 6 f, wake-up association can indicate the STA being waken up by MWID (or GID) and message bit pattern, and can pass through Time List Indicate the wakeup time for the STA being each waken up.Optionally, the Multi User WU Info can also carry communication total duration, Wake-up association duration etc..Optionally, in another frame format, which may also include MAC header (such as MAC Header), frame Content (such as Frame Body) and the one or more fields of FCS, or may also include other fields.Wherein, the STA being waken up List (such as AID or WID), MWID or GID can also be by the address fields in 802.11ba (in such as MAC Header field The domain Address carry) carry, waking up duration such as Time List or Slot Length can be carried by content frame part, The content frame field can also carry initial reservation duration, communication total duration, wake-up association duration etc..For example, as shown in figure 6g, MAC Header can carry STA list (such as AID or WID), MWID or the GID being waken up, and content frame part, which carries, to be waken up Duration；As shown in figure 6h, if MAC Header can carry MWID or GID of the STA being waken up etc., it may further indicate that the MWID Or the STA that GID is waken up, for example the STA list for indicating the STA being waken up in the MWID or GID is carried by content frame part. Frame format and the initial reservation duration of wake-up association instruction for wake-up association, the scheduling such as wakeup time that each STA is waken up letter The indicating mode of breath, the application is without limitation.

Optionally, this initially retain duration can explicit instruction or implicit instruction, for example the wake-up association can directly carry this The initial occurrence for retaining duration；Alternatively, time parameter mark can be carried in the wake-up association, pass through pre-set time parameter Mark and the corresponding relationship of initial retention indicate the initial reservation duration.

502, the WUR of STA1 and STA2 closes (WUR:off).

Further, STA1 and STA2 can close the WUR of itself after receiving the wake-up association, to save battery The energy.

503, STA1 determines the time 1 of PCR opening according to the wake-up association, and opens PCR (PCR:on) in the time 1, with AP carries out data interaction.

Specifically, assuming to determine that STA1 is first waken up according to the wake-up association, then STA1 can be true according to the initial reservation duration Make the wakeup time of itself.For example, initial 40ms a length of when retaining, then STA1 can 40ms after receiving wake-up association or AP send wake-up association after 40ms when open PCR (or can also be communicated with other STA) is communicated with AP.Its In, the wake-up duration of STA can be the opening duration of the PCR of the STA.

When being communicated, STA1 can send PS-Poll frame, data frame either control frame such as ACK frame etc. to AP, with to AP reports that this STA1 is waken up, and AP can send a confirmation response message such as ACK to STA1.STA1 receives the ACK that AP is returned, into And data interaction is carried out with AP, and send ACK to AP after data interaction completion.Alternatively, it is optional, when reaching the wake-up of STA1 Between when, STA1 keeps silent, and AP is waited to send 802.11 frames, such as data frame, control frame to STA1, and STA1 can receive 802.11 frame, and then PS-Poll frame, data frame either control frame such as ACK frame etc. are sent to AP, it thus can reduce STA Expense.

504, STA1 closes PCR (PCR:off).

505, STA2 determines the time 2 of PCR opening according to the wake-up association, and opens PCR (PCR:on) in the time 2, with AP carries out data interaction.

Specifically, STA2 can be according to the initial wakeup time for retaining the determining wake-up duration with STA1 of duration and going out itself. For example, the wake-up duration of initial a length of when retaining 40ms, STA1 and STA2 are 2ms, then STA2 can receive wake-up association it Rear 40+2=42ms or AP opens PCR when sending the 42ms after wake-up association and is communicated with AP.Further, STA1 can be After wakeup time terminates, such as in 42ms closing PCR, alternatively, if STA1 completes communication before the 42ms, it can also be direct PCR is closed, to save battery power.

506, STA2 closes PCR (PCR:off).

Further, STA2 can close PCR after wakeup time terminates, such as in the 42+2 (40+2+2)=44ms, Alternatively, if STA2 completes communication before the 44ms PCR can also be closed, directly to save battery power.

507, STA1 and STA2 opens WUR (i.e. PCR:off, WUR:on).

Further, after the corresponding all STA being waken up of the wake-up association complete communication, each STA, that is, openable WUR.For example, STA1 and STA2 completes to communicate in the 44ms, WUR can be opened in the 44ms, to listen to new wake-up association.? Can according to communication total duration duration after open WUR.

It is further alternative, when AP can also inform the wake-up for participating in each STA that multi-user wakes up communication by other frames It is long.After each STA gets the wake-up duration, the wake-up duration of each STA can be reserved for, and can be using the wake-up duration as each The default value of STA, in order to subsequent use.To can no longer carry the wake-up duration information of STA in wake-up association, make it possible to The corresponding data volume of duration in wake-up association is reduced, this just further reduced overhead.

Further alternative, each STA can also carry out wake operation according to cycle information, such as corresponding according to the cycle information Time interval carry out wake operation, until reach the corresponding wake-up times of the cycle information, to further decrease overhead. Wherein, which can carry in wake-up association, can carry in other frames, such as can be in wake-up association or other frames A field is further added by carry the cycle information；Alternatively, the cycle information can be preset to obtain, the application is without limitation. For example, cycle information instruction time interval is 60ms, wake-up times are 3 times, then STA1 and STA2 can carry out one every 60ms Secondary wake operation, wakeup process please refers to foregoing description, and terminates after executable 3 wake operations (180ms), opens WUR Listen to new wake-up association.

It is further alternative, if AP in preset time range (such as within the scope of above-mentioned communication total duration or certain One STA is corresponding to be waken up within the scope of duration) response that does not receive the STA, waking up the STA using unicast (can be subsequent Some time, or distribute the time of this STA), for example send a wake-up association to the STA, with realize and the STA it is logical Letter.

In embodiments of the present invention, AP can by indicating the initial wake-up duration for retaining duration and each STA in wake-up association, Enable each STA according to initial the wake-ups duration for retaining duration and each STA determine that itself opening PCR communicated when Between, it is communicated so that STA is realized in itself wakeup time wake-up, other times close PCR and WUR, rather than are connecing It receives wake-up association and opens PCR immediately later, to save the battery power of wireless device, help avoid the wave of battery power Take.
