Abstract

A method for providing a mode of wireless local area network (WLAN) operation is disclosed. The method includes: sending an association request from a wireless station (STA) over a discovery channel; receiving an association response at the STA over the discovery channel in response to the association request; and associating the STA to provide a multi-user (MU) enhanced distributed channel access (EDCA) mode using a scheduled access channel.

First claim

What is claimed is:

1. A method for providing a mode of wireless local area network (WLAN) operation comprising:
sending an association request from a wireless station (STA) over a discovery channel;
receiving an association response at the STA over the discovery channel in response to the association request; and
associating the STA to provide a multi-user (MU) enhanced distributed channel access (EDCA) mode using a scheduled access channel.

2. The method of claim 1 , wherein the discovery channel and scheduled access channel may belong to either a single frequency band or a dual frequency band including 6 GHz frequency.

3. The method of claim 1 , wherein the STA receives trigger signals and provides data during a scheduled access period.

4. A method for providing a mode of wireless local area network (WLAN) operation comprising:
receiving an association response at a wireless station (STA) over a discovery channel in response to an association request;
associating the STA on a discovery channel to provide a multi-user (MU) enhanced distributed channel access (EDCA) mode using a scheduled access channel;
sending a buffer status report (BSR) including a bandwidth requirement from the STA in the scheduled access channel;
receiving an acknowledgement at the STA in response to the BSR; and
starting a timer at the STA in response to the acknowledgement.

5. The method of claim 4 , further comprising:
determining that a grant received by the STA contains one or more resource units (RUs) allocated for the STA that satisfy the bandwidth requirement;
stopping the timer; and
sending one or more data frames from the STA in the scheduled access channel.

6. The method of claim 5 , wherein the one or more data frames are provided by the STA in a scheduled access period assigned for the scheduled access channel.

7. The method of claim 4 , further comprising:
determining that the timer is expired before receiving a trigger signal; and
sending one or more data frames from the STA using legacy EDCA in the scheduled access channel.

8. The method of claim 4 , further comprising:
determining that no trigger signal is received at the STA; and
sending one or more data frames from the STA using legacy EDCA in the scheduled access channel.

9. The method of claim 4 , wherein the STA receives a high efficiency operation element.

10. The method of claim 9 , wherein the high efficiency operation element includes one or more enhanced multi-user (MU) EDCA operation subfields corresponding to a plurality of access categories.

11. The method of claim 10 , wherein the plurality of access categories includes at least one of a best effort access category, a background access category, a video access category, and a voice access category.

12. The method of claim 11 , wherein, when a bit corresponding to each of the plurality of access categories is set, an enhanced multi-user EDCA operation for network traffic is enabled.

13. The method of claim 10 , wherein the mode of WLAN operation for an access category among the plurality of access categories is determined based on a traffic type or an application setup.
