Problems solved by technology

[0004] In the above confirmation mechanism, before the STA sends confirmation information to AP1, AP1 needs to receive the forwarded data from AP2. In many scenarios, due to the short SIFS time, the data volume of the uplink data frame forwarded by AP2 to AP1 is large. It cannot be completed within the short frame gap, which affects AP1 sending confirmation information to STA

Embodiment 1

[0100] Embodiment 1, the access point jointly receives the uplink data sent by the station

[0101] 201. A first access point sends a first trigger frame to a station.

[0102] The first access point sends a first trigger frame to the station, wherein the first trigger frame is used to instruct the station to send uplink data to the first access point, so that the station sends the first trigger frame to the first access point according to the trigger instruction of the first trigger frame Send uplink data.

[0103] 202. The second access point sends a second trigger frame to the station.

[0104] While the first access point sends the first trigger frame to the station, the second access point sends a second trigger frame to the station, where the second trigger frame is used to instruct the station to send uplink data to the second access point, to The station is made to send uplink data to the second access point according to the trigger indication of the second trigger f...

Embodiment 2

[0150] Embodiment 2, the access point jointly sends downlink data to the station

[0151] 701. The first access point sends a synchronization signal to the second access point.

[0152] The first access point sends a synchronization signal to the second access point, where the synchronization signal is used to instruct the second access point to jointly transmit downlink data with the first access point.

[0153] In one example, before the first access point sends the synchronization signal to the second access point, the first access point also sends a data field to the second access point, so that the second access point obtains The sent data field generates downlink data, and sends the downlink data according to the instruction of the synchronization signal.

[0154] 702. The first access point sends a downlink data frame to the station, where the downlink data frame includes a data field.

[0155] After the first access point sends the synchronization signal, the first a...

Embodiment 3

[0196] Embodiment three, such as Figure 12 Shown is a schematic diagram of an embodiment of the first access point in this application, the first access point includes:

[0197] A sending unit 1202, configured to receive an uplink data frame sent by a station, where the uplink data frame includes a data field;

[0198] The receiving unit 1201 is configured to demodulate the received data field to obtain first data acknowledgment information, the first data acknowledgment information is used to indicate the data block successfully received by the first access point, and receive the second received data block second data acknowledgment information sent by the access point, where the second data acknowledgment information is used to indicate the data block successfully received by the second access point;

[0199] The processing unit 1203 is configured to send an acknowledgment frame to the above-mentioned station according to the above-mentioned first data acknowledgment infor...

The method of the present application includes: the first access point receives the uplink data frame sent by the station, and the uplink data frame includes a data field; the first access point demodulates the received data field to obtain the first data confirmation information , the first data acknowledgment information is used to indicate the data block successfully received by the first access point; the first access point receives the second data acknowledgment information sent by the second access point, and the second The data confirmation information is used to indicate the data block successfully received by the second access point; the first access point sends a confirmation frame to the station according to the first data confirmation information and the second data confirmation information , the acknowledgment frame is used to indicate the data block successfully jointly received by the first access point and the second access point.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data joint transmission method and related equipment, wherein the data joint transmission method includes joint transmission of uplink data and downlink data. Background technique [0002] In wireless local area network (wireless local area network, WLAN) and other wireless communication systems, the internal communication of basic service set (BSS) introduces spatial multiplexing, and the respective access points (access point, AP) in different BSS Perform data communication with stations (stations, STAs) separately, and there is no data transmission between APs and STAs between different BSSs. Media access control (medium access control, MAC) frame is also called media access control protocol data unit (MAC protocol data unit, MPDU). In order to improve the transmission rate of MPDU, aggregated MPDU (aggregated MPDU, A-MPDU) frame for data transmission...
