OFDMA SOUNDING FOR WLAN SYSTEM |
摘要 |
In wireless communications, an access point may send a first frame and a second frame to multiple stations. In one aspect, the first frame may be a frame for initiating a sounding protocol. The first frame may include subband-related information. In response to the first and second frames, one or more stations may generate beamforming feedback information based on content of the second frame according to the subband-related information of the first frame. The beamforming feedback information may include average signal-to-noise ratios (SNRs), where an SNR may be for a space-time stream averaged over data subcarriers in a subband. The stations may send a third frame(s) that includes the beamforming feedback information to the access point. The access point may generate, and transmit to the stations, a beamforming matrix based on the third frame(s). Other methods, apparatus, and computer-readable media are also disclosed. |

1. A station for facilitating communication in a wireless network for multi-user transmission, the station comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more processors configured to cause:
receiving a first frame;receiving a second frame associated with the first frame;generating a beamforming report, wherein the beamforming report comprises a plurality of average signal-to-noise ratio (SNR) values, and each of the plurality of average SNR values is associated with a respective subband of a bandwidth to be reported; andproviding a third frame for transmission, wherein the third frame comprises the beamforming report. |
