Abstract: The disclosure provides for rate adaptation based on channel power tracking in wireless communications. An Access Point (AP) may measure a full-band channel quality information (CQI) for a plurality of wireless stations associated with the AP and allocate a sub-band resource unit from the plurality of sub-band resource units to a wireless station based on the full-band CQI. Aspects of the disclosure also include techniques for adjusting a data rate associated with the wireless station based on a channel power of the sub-band resource unit.

Abstract: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to techniques for wireless communications by an apparatus comprising receiving a packet via a wireless channel, determining a parameter indicative of frequency selectivity of the channel, selecting a smoothing filter based on the parameter; and applying the smoothing filter to process at least one portion of the packet.
