Abstract: Beamforming may be used in MIMO communication systems to further enhance spectral efficiency. Beamforming refers to beamed transmissions to a single destination (e.g., a station) at a time, to enhance the rate and/or range of transmission. To perform beamforming from a source to one or more destinations, a channel and/or beamforming matrices corresponding to the channel needs to be known at the source, which may be obtained as feedback from the destination. However, the beamforming matrices may not be smooth over frequency as it is fed back from the destination. Therefore, certain aspects of the present disclosure provide beamforming feedback options, resulting in the smoothness of a beamforming matrix.

Abstract: Methods, systems, and devices are described for selectively enabling legacy protection in a WLAN. A method may include receiving, by an access point, a DSSS signal from a station, and activating legacy protection within a WI_AN of the access point based at least in part on the received DSSS signal. For instance when a station cannot be initially detected, the access point may transmit an OFDM signal indicating a NAV period associated with a remote station initial access period. The access point may then receive a DSSS transmission from a remote station during the remote station initial access period. A method may include receiving, at a wireless station, an indication of a NAV period associated with remote station initial access, monitoring for radio transmissions during the NAV period, and transmitting a DSSS signal during the NAV period based on the monitoring.
