Abstract

Claims (62)

1. A method for data processing, performed by a first Access Point (AP), the method comprising:

acquiring resource allocation information of one or more second Basic Service Sets (BSSs) that use a same frequency band as a first BSS for the first AP, wherein the resource allocation information is reported by a station (STA) within both the first BSS and the one or more second BSSs; and

allocating, according to the resource allocation information, a resource to the STA within the first BSS;

wherein the allocating, according to the resource allocation information, a resource to the STA within the first BSS comprises:

determining, according to the resource allocation information, a number of BSSs which associate with the STA in an Overlapping Basic Service Set (OBSS) between the first BSS and the second BSSs; and

assigning, according to an Orthogonal Frequency Division Multiple Access (OFDMA) mechanism based on the number of BSSs determined, one or more Resource Units (RUs) to the STA within the OBSS, to prevent different STAs within the OBSS from using a same RU at a same time.

2. The method according to claim 1 , wherein acquiring the resource allocation information of the one or more second BSSs that use the same frequency band as the first BSS for the first AP further comprises:

receiving resource allocation information of the one or more second BSSs which is broadcast by a second AP.

3. The method according to claim 2 , wherein receiving the resource allocation information of the one or more second BSSs which is broadcast by the second AP comprises:

receiving periodically the resource allocation information of the one or more second BSSs which is broadcast by the second AP configured with the second BSSs.

4. The method according to claim 1 , wherein receiving the resource allocation information of the one or more second BSSs which is reported by the STA within both the first BSS and the one or more second BSSs comprises:

receiving the resource allocation information of the one or more second BSSs which is periodically reported by the STA within both the first BSS and the one or more second BSSs.

5. The method according to claim 1 , further comprising:

issuing a report instruction;

wherein receiving the resource allocation information of the one or more second BSSs which is reported by the STA within both the first BSS and the one or more second BSSs comprises:

receiving resource allocation information of the one or more second BSSs that is reported based on the report instruction by the STA within both the first BSS and the one or more second BSSs.

6. The method according to claim 1 , wherein acquiring resource allocation information of the one or more second BSSs that use the same frequency band as the first BSS for the first AP comprises:

acquiring resource allocation information of the one or more second BSSs that use the same frequency band over multi-links as the first BSS for the first AP, wherein the multi-links correspond to operation bandwidths over different frequency bands or different operation bandwidths over a same frequency band.

7. The method according to claim 1 , the resource allocation information comprises: identifiers of the one or more second BSSs and resource allocation information of RU, wherein the resource allocation information of RU at least comprises resource location information of RU.

8. The method according to claim 7 , wherein the resource allocation information of RU further comprises at least one of:

information about an STA assigned with RU;

a start time of RU in time domain and a duration of RU in time domain;

an index of an operation bandwidth for RU over multi-links;

a link identifier of a link corresponding to RU; or

a number of RUs.

9. The method according to claim 1 , further comprising:

broadcasting resource allocation information of the first BSS.

10. A method for data processing performed by a station (STA), the method comprising:

receiving resource allocation information of one or more second Basic Service Sets (BSSs) which is broadcast by a second Access Point (AP); and

reporting the resource allocation information of the one or more second BSSs to a first AP configured with a first BSS, wherein the first BSS and the one or more second BSSs are of a same frequency band;

wherein the resource allocation information is for the first AP to:

determine, according to the resource allocation information, a number of BSSs which associate with the STA in an Overlapping Basic Service Set (OBSS) between the first BSS and the second BSSs, and

assign, according to an Orthogonal Frequency Division Multiple Access (OFDMA) mechanism based on the number of BSSs determined, one or more Resource Units (RUs) to the STA within the OBSS, to prevent different STAs within the OBSS from using a same RU at a same time.

11. The method according to claim 10 , wherein reporting the resource allocation information of the one or more second BSSs to the first AP configured with the first BSS comprises:

reporting periodically the resource allocation information of the one or more second BSSs to the first AP configured with the first BSS.

12. The method according to claim 10 , further comprising:

receiving a report instruction;

wherein reporting the resource allocation information of the one or more second BSSs to the first AP configured with the first BSS comprises:

reporting, according to the report instruction, the resource allocation information of the one or more second BSSs to the first AP configured with the first BSS.

13. A communication device, comprising:

a transceiver;

a memory; and

one or more processors connected to the transceiver and the memory,

wherein the one or more processors are collectively configured to:

acquire resource allocation information of one or more second Basic Service Sets (BSSs) that use a same frequency band as a first BSS for an first AP, wherein the resource allocation information is reported by a station (STA) within both the first BSS and the one or more second BSSs; and

allocate, according to the resource allocation information, a resource to the STA within the first BSS;

wherein the resource is allocated by:

determining, according to the resource allocation information, a number of BSSs which associate with the STA in an Overlapping Basic Service Set (OBSS) between the first BSS and the second BSSs; and

assigning, according to an Orthogonal Frequency Division Multiple Access (OFDMA) mechanism based on the number of BSSs determined, one or more Resource Units (RUs) to the STA within the OBSS, to prevent different STAs within the OBSS from using a same RU at a same time.

14. A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores computer-executable instructions, in response to the computer-executable instructions being executed by a processor of the first AP, cause the AP to perform the method according to claim 1 .

15. The communication device according to claim 13 , wherein acquiring the resource allocation information of the one or more second BSSs that use the same frequency band as the first BSS for the first AP comprises at least one of:

receiving resource allocation information of the one or more second BSSs which is broadcast by a second AP.
