Abstract
A method and apparatus may be used in Very High Throughput (VHT) Wireless Local Area Network (WLAN) management actions. Management action frames such as VHT Action frames may be used to implement VHT features in WLANs. Extensions to 802.11 Action frames may be used to support VHT features and provide backward compatibility. VHT Management Actions may be supported with VHT Action frames and VHT extensions to 802.11 Action frames in various categories such as Direct Link Setup (DLS), Public, Spectrum Management and high throughput (HT). An access point (AP) or a wireless transmit/receive unit (WTRU) may indicate VHT capability by way of signaling.
Claims20
A method for use in wireless communications, the method comprising:
- receiving a sounding packet at a station (STA) configured to support a Very High Throughput (VHT) transmission;
- and
- transmitting, from the STA, a VHT Compressed Beamforming frame to an access point (AP), wherein the VHT Compressed Beamforming frame is an Action No Acknowledgement (ACK) frame and includes a VHT multiple input multiple output (MIMO) Control field, wherein the VHT MIMO Control field indicates a channel width related to a multi-channel non-contiguous spectrum transmission associated with the sounding packet.
A station (STA) comprising:
- a receiver configured to receive a sounding packet;
- and
- a transmitter configured to transmit a Very High Throughput (VHT) Compressed Beamforming frame, wherein the VHT compressed beamforming frame is an Action No Acknowledgement (ACK) frame and includes a VHT multiple input multiple output (MIMO) Control field, wherein the VHT MIMO Control field indicates a channel width related to a multi-channel non-contiguous spectrum transmission associated with the sounding packet.
An access point (AP) comprising:
- a transmitter configured to transmit a sounding packet;
- and
- a receiver configured to receive a Very High Throughput (VHT) Compressed Beamforming frame, wherein the VHT Compressed Beamforming frame is an Action No Acknowledgement (ACK) frame and includes a VHT multiple input multiple output (MIMO) Control field, wherein the VHT MIMO Control field indicates a channel width related to a multi-channel non-contiguous spectrum transmission associated with the sounding packet.
