Abstract
Methods and apparatuses of dynamic subband operation (DSO) are provided. A station (STA) device receives a subband switch control frame from an access point (AP). The subband switch control frame indicates a transition, by the STA device, to a secondary channel. In response to receiving the subband switch control frame, the STA device transitions from a primary channel to the secondary channel. The subband switch control frame indicates one or more channels in the secondary channel, and the one or more channels are a subset of total available channels in the secondary channel.
Claims20
A method of dynamic subband operation (DSO), comprising:
- receiving, by a station (STA) device, a subband switch control frame that indicates a transition, by the STA device, to a secondary channel;
- and
- transitioning, by the STA device, from a primary channel to the secondary channel in response to receiving the subband switch control frame,
- wherein the subband switch control frame indicates one or more channels in the secondary channel, and wherein the one or more channels are a subset of total available channels in the secondary channel.
A method of dynamic subband operation (DSO), comprising:
- determining, by an access point (AP), one or more channels in a secondary channel;
- and
- transmitting, to a station (STA) device, a subband switch control frame that causes the STA device to transition from a primary channel to the one or more channels in the secondary channel,
- wherein the one or more channels are a subset of total available channels in the secondary channel.
An apparatus comprising:
- a memory;
- and
- a processor, operatively coupled to the memory, to:
- receive a subband switch control frame that indicates a transition to a secondary channel;
- and
- transition from a primary channel to the secondary channel in response to receiving the subband switch control frame,
- wherein the subband switch control frame indicates one or more channels in the secondary channel, and wherein the one or more channels are a subset of total available channels in the secondary channel.
