Abstract
Certain aspects of the present disclosure relate to timers used to control switching from SU to MU transmission modes. In some examples, a frame is generated having an indication of multiple timer values for one or more wireless devices to be used for switching from a multiple user (MU) mode to a single user (SU) mode. In other examples, when to switch from a MU mode to a SU mode is determined based on multiple timer values obtained from a frame, and one or more second frames are generated for transmission via the SU mode or the MU mode based on the determination.
Claims30
An apparatus for wireless communications, comprising:
- a processing system configured to generate a frame having an indication of multiple timer values for one or more wireless devices to be used for switching from a multiple user (MU) mode to a single user (SU) mode, wherein the multiple timer values comprise different timer values for different access categories (ACs) of an MU enhanced distributed channel access (EDCA) parameter set element included in the frame;
- and
- an interface for outputting the frame for transmission.
An apparatus for wireless communications, comprising:
- an interface for obtaining a first frame having an indication of different timer values for different access categories (ACs) of a multiple user (MU) enhanced distributed channel access (EDCA) parameter set element included in the first frame;
- and
- a processing system configured to:
- determine when to switch from the MU mode to a single user (SU) mode based on the multiple timer values, and
- generate one or more second frames for transmission via at least one of the SU mode or the MU mode, based on the determination.
An apparatus for wireless communications, comprising:
- an interface for obtaining a first frame indicating single user (SU) enhanced distributed channel access (EDCA) parameters for at least a first access category (AC) and a second frame having an indication of timer values for different ACs of multiple user (MU) EDCA parameters;
- and
- a processing system configured to:
- switch from an MU mode to an SU mode based on the timer values;
- determine, while in the SU mode for the first AC, at least one of when or whether to use the SU EDCA parameters for the first AC, and
- generate one or more third frames of the first AC for transmission via the SU mode, based on the determination.
An apparatus for wireless communications, comprising:
- an interface for obtaining a frame having an indication of different timer values for different access categories (ACs) of a multiple user (MU) enhanced distributed channel access (EDCA) parameter set element included in the frame;
- and
- a processing system configured to:
- initiate a timer used for switching from a MU mode to a single user (SU) mode based on at least one timer value of the different timer values, and
- maintain the timer upon at least one of entering or exiting a first power mode in which one or more components of the apparatus are powered down.
