Abstract

The present disclosure provides a beamforming report transmission method, a communication node and a computer-readable storage medium, the beamforming report transmission method includes: receiving, by a first communication node, a beamforming report sent by a third communication node, where the beamforming report includes at least one of a beamforming result or a channel quality measurement result between the third communication node and at least one second communication node.

First claim

What is claimed is:

1. A beamforming report transmission method performed by a first communication node, comprising:
receiving, by the first communication node, a beamforming report sent by a third communication node, the beamforming report comprising at least one of a beamforming result or a channel quality measurement result between the third communication node and at least one second communication node, wherein the first communication node is an access point, and the third communication node is a station associated with the first communication node;
sending, by the first communication node, a beamforming report request to the third communication node for indicating the third communication node to send the beamforming report to the first communication node;
wherein the beamforming report request comprises all of following information:
identification information of each of the at least one second communication node,
indication information of a beamforming report type, indication information of more beamforming report requests, indication information of a feedback segment retransmission, identification information of the third communication node, and allocation information of a resource,
wherein the indication information of more beamforming report requests is configured to indicate whether a new beamforming report request is to be sent from the first communication node to the third communication node during a current service period or a current transmission opportunity;
wherein the indication information of the feedback segment retransmission is configured to indicate that the beamforming report sent by the third communication node comprises at least one of a feedback segment of the beamforming result or a feedback segment of the channel quality measurement result, which is indicated by the indication information of the feedback segment retransmission;
wherein the indication information of the third communication node is configured to indicate the third communication node for sending the beamforming report; and
wherein the allocation information of the resource is configured to indicate a resource unit of the third communication node for sending the beamforming report.

2. The method of claim 1 , wherein the beamforming report comprises at least one of: identification information of each of the at least one second communication node; or indication information of a beamforming report type.

3. The method of claim 2 , wherein, the identification information of each of the at least one second communication node is configured to indicate that the beamforming report comprises at least one of a beamforming result or a channel quality measurement result between the third communication node and said each of the at least one second communication node indicated by the identification information; and the indication information of the beamforming report type is configured to indicate that, in the beamforming report, at least one of a beamforming result or a channel quality measurement result between the third communication node and at least one second communication node associated with the third communication node is carried, or at least one of a beamforming result or a channel quality measurement result between the third communication node and at least one second communication node unassociated with the third communication node is carried, or at least one of a beamforming result or a channel quality measurement result between the third communication node and at least one second communication node associated and/or unassociated with the third communication node is carried.

4. The method of claim 1 , wherein the identification information of each of the at least one second communication node is configured to indicate that the beamforming report sent by the third communication node comprises at least one of a beamforming result or a channel quality measurement result between the third communication node and said each of the at least one second communication node indicated by the identification information.

5. The method of claim 2 , wherein the identification information of each of the at least one second communication node comprises at least one of following information: identification information of a service set, identification information of a member of a multi-communication nodes group, information of a MAC address, identification information of an antenna, and information of an identification bitmap of the at least one second communication node.

6. The method of claim 5 , wherein the identification information of each of the at least one second communication node comprises the information of the identification bitmap of the at least one second communication node, and the information of the identification bitmap of the at least one second communication node comprises at least one bit, wherein each bit is mapped to one second communication node,
wherein a bit of the information of the identification bitmap of the at least one second communication node is configured to be a specific value for indicating the third communication node to send the beamforming report comprising at least one of the beamforming result or the channel quality measurement result between the third communication node and one of the at least one second communication node mapped by the bit configured to be the specific value.

7. The method of claim 1 , wherein the indication information of the beamforming report type is configured to indicate a type of the beamforming report, and the type is at least one of:
a beamforming result between the third communication node and at least one second communication node associated with the third communication node;
a channel quality measurement result between the third communication node and at least one second communication node associated with the third communication node;
a beamforming result between the third communication node and at least one second communication node unassociated with the third communication node;
a channel quality measurement result between the third communication node and at least one second communication node unassociated with the third communication node;
a beamforming result between the third communication node and at least one second communication node associated and/or unassociated with the third communication node; or
a channel quality measurement result between the third communication node and at least one second communication node associated and/or unassociated with the third communication node.

8. A beamforming report transmission method performed by a third communication node, comprising:
sending, by the third communication node, a beamforming report comprising at least one of a beamforming result or a channel quality measurement result between the third communication node and at least one second communication node to a first communication node, wherein the first communication node is an access point, and the third communication node is a station associated with the first communication node;
sending, by the third communication node, the beamforming report, after receiving a beamforming report request sent by the first communication node;
wherein the beamforming report request comprises all of following information:
identification information of each of the at least one second communication node, indication information of a beamforming report type, indication information of more beamforming report requests, indication information of a feedback segment retransmission, identification information of the third communication node, and allocation information of a resource;
and
acquiring, by the third communication node, whether a new beamforming report request is to be sent from the first communication node to the third co
