In the prior art, the structure for the 802.11ac physical layer frames that AP is sent is as shown in Fig. 2 wherein VHT-SIG-A points are
VHT-SIG-A1 and VHT-SIG-A2 two parts, the content that VHT-SIG-A1 is represented is as shown in the table：
Wherein, TXOP_PS_NOT_ALLOWED is used to indicate whether to allow power saving, and 0 represents to allow power saving, and 1 represents not permit
Perhaps power saving.
Existing power conservation techniques are as follows：
TXOP_PS_NOT_ALLOWED is 0 and meets following condition for the moment in the frame that website is received, and can enter to fall asleep
Dormancy state：
1) website is not belonging to the Group ID in the frame that receives；
2) website is mismatched with the Partial AID in the frame received.
Prior art allows the frame of power saving generally to have following two ways：
1) Group ID=0 or 63 in the VHT-SIG-A1 for the physical layer frame that AP is sent, and Partial AID are not equal to 0.
If TXOP_PS_NOT_ALLOWED is set to 0 in VHT-SIG-A1 parts, namely allows power saving, then STA is receiving the physics
According to the information of Partial AID in the physical layer frame after layer frame, judge the STA Partial AID whether with the Partial
AID is matched, if it does not match, into sleep state, if it does, then do not enter sleep state,
2) certain number for belonging in 2 to 62 of Group ID in the VHT-SIG-A1 for the physical layer frame that AP is sent, then Partial
AID is not present.If TXOP_PS_NOT_ALLOWED is set to 0 in VHT-SIG-A1 parts, namely allows power saving, then STA is connecing
Receive after the physical layer frame according to the information of Group ID in the physical layer frame, judge whether the STA itself belongs to the Group
ID, if it is not, then into sleep state, if it is, not entering sleep state.
Therefore, empty packet notifies that (Null Data PacketAnnouncement, NDPA) frame is not allow power saving,
Otherwise by existing rule all STA can be made to enter sleep state, be analyzed as follows：
To support to introduce detection (sounding) measurement correlation in beam forming (Beamforming) transmission, 802.11
Frame.Wherein NDPA frames are used to notify receiving terminal to be spaced short frame pitch (short after being ready for sounding measurements, NDPA frames
Inter-frame space, SIFS) duration, need to send empty data packet frame (Null Data Packet, NDP) is used for receiving terminal
Carry out sounding measurements.
If DATA parts are Group ID=0 or 63 in NDPA frames, VHT-SIG-A1 in the physical layer frame that AP is sent
And Partial AID=0, if TXOP_PS_NOT_ALLOWED is set to 0, namely allow power saving, because Partial AID=0
Mismatched with all STA Partial AID, then all STA enter sleep state after the physical layer frame is received, because
This is needed TXOP_PS_NOT_ALLOWED being set to 1, namely does not allow power saving, and in this case, all STA can not
Into sleep state.
So, AP can only control a STA or belong to same Group ID STA not enter sleep shape in the prior art
State.Do not enter the data message that dormant STA is parsed in physical layer frame, and follow-up behaviour is performed according to data message
Make.
Both the above mode does not support control simultaneously to belong to different Group ID STA sleep state, based on this,
