2) The STA1 transmission rate is less than or equal to a preset value R1;

s4, when the condition indicated by the MAP measurement condition is met, the STA1 measures the indicated candidate AP according to the information of the MAP candidate 1-n, and constructs a measurement Report according to the Report item indicated by Report items;

s5, the STA1 sends a measurement Report according to the mode indicated by the Report mode, and the measurement Report also comprises a signal result of the STA1 for measuring the AP1;

s6, after receiving the measurement report, the AP1 executes the multi-point cooperative operation according to the measurement result,

for example, when the AP1 signal result measured by STA1 in the measurement report is less than or equal to a preset value T1, and there is a signal result in the measured candidate APs that is greater than or equal to a preset value T2, the coordinated multipoint operation may be started. In this process, the AP whose measured signal result value is greater than the preset value T2 among the candidate APs is set as the operating AP and added to the parameter operating set of the coordinated multi-point operation information table of AP 1.

The mode of the coordinated multi-point operation needs to be determined, which may be selected according to the measurement result, for example, when the signal result of the AP1 measured by the STA1 is compared with the signal result of the operating AP, and an absolute value of a difference between the signal result and the signal result is less than or equal to a threshold value T3, a single-point cooperative reception mode, such as a cooperative beamforming mode, a cooperative OFDMA mode, or a dynamic single-point AP selection mode, is selected; for example, when the absolute value of the difference between the signal result of the AP1 measured by the STA1 and the signal result of the operating AP is greater than or equal to the threshold value T4, T4> T3, the coordinated multipoint reception mode, such as the joint reception mode and the dynamic multipoint AP selection mode, is selected.

It should be noted that in the single-point cooperative reception manner, STA1 only sends data to one AP in one period, and STA1 alternately sends data to multiple receiving APs according to a certain rule; in a multipoint cooperative receiving mode, the STA1 in a period can simultaneously send data to a plurality of receiving APs;

s7, the AP1 sends a trigger message to the STA1, instructing the STA1 to start uplink multipoint cooperative operation, where the trigger message includes parameters shown in table 7:

TABLE 7

Parameter(s)	Description of the invention
		Receiving AP	Address of AP for receiving uplink data
Start time	Time for starting uplink multi-point cooperative operation
		MAP session ID	Multipoint collaborative process identification

S8, after the STA1 receives the trigger message, the STA starts to send data to the receiving AP indicated in the trigger message at the time indicated by the start time, and the address of a receiver of the frame bearing the data is set to be an address containing the MAP session ID information; if the receiving AP is in a single-point cooperative receiving mode and is not the AP1, the AP1 also sends a triggering message to the receiving AP to indicate the receiving AP to execute the uplink multi-point cooperative operation; after receiving the trigger message, the receiving AP stores the data and sends the data to the AP1 after receiving the data sent by the STA 1; if the multipoint cooperative operation is carried out, the AP1 sends a triggering message to the receiving AP except the AP1 to indicate the receiving AP to execute the uplink multipoint cooperative operation; after receiving the trigger message, the receiving AP stores the data and sends the data to the AP1 after receiving the data sent by the STA 1; and the Receiving AP determines whether the data is the data sent by the STA1 according to the MAP session ID and the address of the receiver of the received data, if so, the data is stored and then sent to the AP1, otherwise, the data is not stored.

It should be noted that, in the optional embodiment of the present invention, not only the AP1 in the step S7 may send the trigger message to the STA1 to obtain data, but also the AP1 may send the POLL message to obtain data, and the specific method is as follows: the AP1 sends a POLL message to other Receiving APs, and after the other Receiving APs receive the POLL message of the AP1, the other Receiving APs send the stored data sent by the STA1 to the AP1;

in addition, the parameter MAP measurement Element included in the association response in step S2 may not be included in the association response message, and after the STA1 and the AP1 establish a connection, the AP1 may further include the parameter in another message and send the parameter to the STA1, for example, a radio measurement request message, which may be executed in various ways.
