Abstract

A method and system for providing transitioning a station (STA) to an uplink multi-user (UL MU) disable mode and to a UL MU enable mode is provided. According to one embodiment, a method includes entering, with the STA, a UL MU enable mode, and determining whether to transition the STA to a UL MU disable mode based on a predetermined interrupt condition. The predetermined interrupt condition is provided by the STA in the UL MU enable mode to transition the STA to the UL MU disable mode when the STA is unable to respond to a UL MU operation.

First claim

What is claimed is:

1 . A method for transitioning a station (STA) to an uplink multi-user (UL MU) disable mode, comprising;
entering, with the STA, a UL MU enable mode; and determining whether to transition the STA to a UL MU disable mode based on a predetermined interrupt condition, wherein the predetermined interrupt condition is provided by the STA in the UL MU enable mode to transition the STA to the UL MU disable mode when the STA is unable to respond to a UL MU operation.

2 . The method of claim 1 , wherein the predetermined interrupt condition includes an occurrence of channel switching in the UL MU enable mode.

3 . The method of claim 1 , wherein the predetermined interrupt condition includes an occurrence of a co-existence with a medium request in the UL MU enable mode.

4 . The method of claim 1 , wherein the predetermined interrupt condition includes an occurrence of a non-UL MU virtual interface (VIF) active on the same channel as a UL MU VIF in the UL MU enable mode.

5 . The method of claim 4 , wherein if traffic is pending when the non-UL MU VIF is active on the same channel as the UL MU VIF in the UL MU enable mode, then the traffic is transmitted before transitioning to the UL MU disable mode.

6 . A system for transitioning a station (STA) to an uplink multi-user (UL MU) disable mode, comprising;
the STA configured to enter a UL MU enable mode; a memory; and a processor configured to determine whether to transition the STA to the UL MU disable mode based on a predetermined interrupt condition, wherein the predetermined interrupt condition is provided by the STA in the UL MU enable mode to transition the STA to the UL MU disable mode when the STA is unable to respond to a UL MU operation.

7 . The system of claim 6 , wherein the predetermined interrupt condition includes an occurrence of channel switching in the UL MU enable mode.

8 . The system of claim 6 , wherein the predetermined interrupt condition includes an occurrence of a co-existence with a medium request in the UL MU enable mode.

9 . The system of claim 6 , wherein the predetermined interrupt condition includes an occurrence of a non-UL MU virtual interface (VIF) active on the same channel as a UL MU VIF in the UL MU enable mode.

10 . The system of claim 9 , wherein if traffic is pending when the non-UL MU VIF is active on the same channel as the UL MU VIF in the UL MU enable mode, then the traffic is transmitted before transitioning to the UL MU disable mode.

11 . A method for transitioning a station (STA) to an uplink multi-user (UL MU) enable mode, comprising;
entering, with the STA, a UL MU disable mode; and determining whether to transition the STA to the UL MU enable mode based on a predetermined interrupt condition, wherein the predetermined interrupt condition is provided by the STA in the UL MU disable mode to transition the STA to the UL MU enable mode when the STA is able to respond to a UL MU operation.

12 . The method of claim 11 , wherein the predetermined interrupt condition includes an occurrence of a timeout operation in the UL MU disable mode for channel switching.

13 . The method of claim 11 , wherein the predetermined interrupt condition includes an occurrence of a timeout operation in the UL MU disable mode for a co-existence with a medium request.

14 . The method of claim 11 , wherein the predetermined interrupt condition includes an occurrence of a timeout operation in the UL MU disable mode for a non-UL MU virtual interface (VIF) active on the same channel as a UL MU VIF.

15 . The method of claim 11 , further comprising:
transitioning the STA to the UL MU enable mode based on the predetermined interrupt condition; and transitioning the STA back to the UL MU disable mode after a timeout happens for the predetermined interrupt condition in the UL MU enable mode.

16 . A system for transitioning a station (STA) to an uplink multi-user (UL MU) enable mode, comprising;
the STA configured to enter a UL MU disable mode; a memory; and a processor configured to determine whether to transition the STA to the UL MU enable mode based on a predetermined interrupt condition or actively monitoring conditions of the STA, wherein the predetermined interrupt condition is provided by the STA in the UL MU disable mode to transition the STA to the UL MU enable mode when the STA is able to respond to a UL MU operation.

17 . The system of claim 16 , wherein the predetermined interrupt condition includes an occurrence of a timeout operation in the UL MU disable mode for channel switching.

18 . The system of claim 16 , wherein the predetermined interrupt condition includes an occurrence of a timeout operation in the UL MU disable mode for a co-existence with a medium request.

19 . The system of claim 16 , wherein the predetermined interrupt condition includes an occurrence of a timeout operation in the UL MU disable mode for a non-UL MU virtual interface (VIF) active on the same channel as a UL MU VIF.

20 . The system of claim 16 , wherein the processor is further configured to:
transition the STA to the UL MU enable mode based on the predetermined interrupt condition; and transition the STA back to the UL MU disable mode after a timeout happens for the predetermined interrupt condition in the UL MU enable mode.
