20130215947 | DATA FEEDBACK METHODS AND RELATED APPARATUSES - Embodiments of the present invention disclose data feedback methods and related apparatuses. This enables a beamformer to adjust the communication status according to related channel information about a beamformee no matter whether the number of actual active antennas of the beamformee is larger than or equal to the number of columns set by the beamformer in an NDPA message. The data feedback method according to the embodiments of the present invention includes: acquiring, by the beamformee, the number of columns from the NDPA message; detecting the number of active first spatial streams; comparing the number of first spatial streams with the number of columns, and taking the smaller value obtained from the comparison as the number of second spatial streams required for feedback; and feeding back the number of second spatial streams and spatial stream measurement information about the second spatial streams to the beamformer. | 08-22-2013 |

20130272289 | Wireless Local Area Network, Station, and Access Point and Methods for Accessing Thereof - Embodiments of the present invention provide a method for accessing a wireless local area network, a station, and an access point. The method includes: receiving, by a station, a beacon or a probe response from an access point, where the beacon or the probe response carries configuration version information; and executing, by the station, a GAS query according to the configuration version information carried in the beacon or the probe response. In the embodiments of the present invention, the access point sends the configuration version information to the station, so that the station executes the GAS query according to the configuration version information, thereby improving access efficiency. | 10-17-2013 |
