First, the concepts related to the embodiments of the present application are explained:

candidate Set: a group of network devices that may initiate or participate in a multipoint cooperation may be provided. The candidate set may be static, preset by an administrator in advance, or dynamic, and is automatically generated according to actual deployment during system operation, for example, after a group of access points is installed, the access points adjacent to the group of access points are preset in a configuration file of the group of access points as the candidate set for deployment, or during operation, the access points establish the candidate set according to the neighbor measurement result reported by the terminal.

Operation Set: a set of network devices performing multipoint cooperating operations.

The network device may be a Transmission Point (TRP), such as a base station, a router, or an Access Point (AP), and multiple network devices may interact with each other to implement multipoint cooperative operation. The plurality of network devices may be different network devices or the same network device. Further, the plurality of network devices may be independent network devices or may be integrated together. The terminal device can transmit information to a plurality of network devices, and can also receive data information transmitted by a plurality of different network devices. Illustratively, the terminal device may be a mobile phone, a vehicle-mounted terminal device, a projector, or the like. In the embodiment of the present application, a network device is taken as an access point as an example for explanation, and it is assumed that a terminal device STA1 is currently connected with an access point AP1.

Fig. 1 is a flowchart of a method for multi-point cooperative operation according to an embodiment of the present disclosure. As shown in fig. 1, the method of multi-point cooperative operation includes the following steps:

and S101.AP1 determines to execute multipoint cooperative operation.

In some embodiments, the AP1 may determine whether to perform the coordinated multi-point operation by itself, for example, the AP1 may determine whether to perform the coordinated multi-point operation according to a packet loss rate or an error rate of data transmission with the STA1 or a measured signal quality of the terminal, for example, when the packet loss rate or the error rate is high, it may determine to perform the coordinated multi-point operation, and for example, when the signal quality is poor, it may determine to perform the coordinated multi-point operation.

In some other embodiments, the AP1 may also determine whether to perform the coordinated multipoint operation according to the request of the STA1, which specifically includes:

and S1001, when the STA1 measures that the channel quality (such as CSI, SINR or RSSI and the like) between the STA1 and the AP1 is lower than a preset threshold value T1, the STA1 sends a multipoint coordination request message to the AP1, wherein the multipoint coordination request message comprises an indication whether to enable multipoint coordination operation, a coordination operation mode supported by the STA1 and the channel quality measured by the STA1 and between the STA1 and the AP1.

S1002. After receiving the multipoint coordination request message, the AP1 determines whether to execute the multipoint coordination operation according to the information in the multipoint coordination request message, and the specific mode includes but is not limited to the following methods:

1) The AP1 determines whether to support the requested multipoint cooperative operation according to the cooperative operation mode and the self capability in the multipoint cooperative request message, if so, executes the following operation, and if not, rejects the multipoint cooperative request of the STA1.

2) The AP1 determines whether to support the requested cooperative operation according to the cooperative operation mode and the self capability in the multipoint cooperative request message, if not, the multipoint cooperative request of the STA1 is rejected, if so, the multipoint cooperative request is judged according to the value of the channel quality in the request message and a preset threshold value, if the value is lower than or equal to the threshold value, the following operation is executed, and if the value is higher than the threshold value, the multipoint cooperative request of the STA1 is rejected.

S1003. If the AP1 rejects the multipoint coordination request of the STA1, sending a multipoint coordination response message to the STA1, wherein a parameter status code value is set in the response message to indicate that the multipoint coordination operation is rejected. Otherwise, step S102 is executed.

And S102, AP1 sends a cooperative operation request message to the access points in the candidate set, wherein the cooperative operation request message comprises a cooperative target, a cooperative operation mode and resource information, so that the access points in the candidate set can detect the channel quality between the access points and the terminal equipment indicated by the cooperative target in the cooperative operation request message according to the resource information in the cooperative operation request message.

In the embodiment of the application, a cooperative target in the cooperative operation request message is set as an address of the STA 1; the cooperative operation mode may be JT (joint transmission), COFDM (cooperative orthogonal frequency division multiplexing), CBF (cooperative beam forming), or CSR (cooperative spatial multiplexing); the resource information may include one or more of time and frequency resource blocks, BF beamforming configuration, and SS (space stream) resources.

Optionally, the cooperative operation request message further includes at least one of timing information, capability information of the STA1, and encryption information. The encryption information may be encryption information for the STA1 to communicate with the AP1, or may also be encryption information that the STA1 needs to use in the multipoint cooperative operation, which is not limited in this embodiment of the application.

It should be noted that the AP1 stores candidate set information, where the candidate set information includes an identifier of an access point in the candidate set, and the identifier of the access point may be a parameter capable of identifying the access point, such as an address of the access point. If the candidate set includes AP1, therefore AP1 only needs to send the cooperative operation request message to other APs except AP1, and the embodiments of the present application refer to the other APs except AP1 in the candidate set as APx.

If the APx does not support or approve the multipoint cooperative operation, the APx sends a cooperative operation response message to the AP1, and the value of the parameter status code in the response message is set as 'reject', which indicates that the multipoint cooperative operation is not supported or approved.

If the APx supports or agrees to the multi-point cooperative operation, probing the channel quality between the APx and the terminal device (STA 1 in the embodiment of the present application) indicated by the cooperative target in the cooperative operation request message according to the resource information in the cooperative operation request message, where the probing process includes:

1) APx sends an NDPA (Null Data Packet Announcement) message to STA1, telling STA1 that it is about to send an NDP.

2) The APx transmits the NDP, which is a data frame not containing valid information, to the STA1 according to the resource information in the cooperative operation request message.

3) STA1 performs channel measurement according to the received NDP.

And S103, AP1 receives the channel measurement result between the access point and the terminal equipment in the candidate set, and constructs an operation set according to the channel measurement result.

In some embodiments, AP1 may receive the channel measurement results from APx, including: the STA1 actively sends the channel measurement result to the APx, or sends the channel measurement result to the APx after receiving a feedback request message sent by the APx; the APx sends a cooperative response message to the AP1, where the response message includes the address of the STA1 and the channel measurement result between the APx and the STA1, and optionally, the cooperative response message may further include a parameter status code, and the value is set to "accept", which indicates that the APx agrees or supports the multipoint cooperative operation.

In some other embodiments, AP1 may receive the channel measurement results from STA1, including: the STA1 actively sends the channel measurement result to the AP1, or sends the channel measurement result to the AP1 after receiving the feedback request message sent by the AP1.

It should be noted that the operation set may include AP1 or may not include AP1, and in the embodiment of the present application, other APs except AP1 in the operation set are referred to as APy.

Illustratively, the AP1 may select the AP with the channel measurement result size ranking N top as a member of the operation set, where N = [ 25/(lnM × lnCSI) ], where M is the current user number of the AP1 and CSI is the channel quality between the STA1 and the AP1. For example, the AP1 may first sort according to the received channel measurement results between the APx and the STA1 from large to small; and then selecting the APx of the first N sorted APx as the member in the operation set.

Optionally, AP1 may also send the operation set to STA1. If the AP1 decides whether to perform the coordinated multipoint operation according to the request of the STA1 in step S101, the AP1 may transmit an operation set to the STA1 in a coordinated multipoint response in response to the coordinated multipoint request message of the STA1.STA1 may establish a connection with an APy other than AP1 according to the received operation set, for example, send a connection request message (e.g., association request message) to the APy, optionally, a cause code parameter may be further set in the connection request message, and the value of the cause code parameter is set to "coordination operation", which indicates that the reason for requesting the connection is the coordinated operation. After receiving the connection request message, if the connection request message includes a cause code and the value is "coordination operation", comparing the address of the sender in the connection request message, and if the address is the same as the address indicated by the coordination target in the coordination operation request message sent by the AP1 in step S102, sending a connection response message (e.g., an association response message) to the STA1 to indicate that the connection with the STA1 is accepted.

And S104, the AP1 and the access point in the operation set cooperate to send data to the terminal equipment.

In some embodiments, the sending, by the AP1, data to the terminal device in cooperation with the access point in the operation set includes: the AP1 sends data needing to be sent to the STA1 to the APy; the AP1 sends a multipoint cooperative trigger message to the APy, wherein the multipoint cooperative trigger message comprises sending time information (such as sending start time and sending duration TXOP), resource information and a cooperative operation mode; after receiving the multipoint cooperative trigger message, the APy sends data to the STA1 according to the resource information in the multipoint cooperative trigger message by using the cooperative operation manner indicated in the multipoint cooperative trigger message according to the sending time indicated in the multipoint cooperative trigger message.

Alternatively, if in step S101, the AP1 decides whether to perform the multipoint cooperative operation according to the request of the STA1, the STA1 may further include the address of the received APy in the operation set information and transmit the operation set information to the AP1 after receiving the connection response message transmitted by the APy. At this time, in step S104, AP1 transmits data to STA1 in cooperation with the APy indicated in the received operation set information.
