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: A device includes a memory, a processor, and a transceiver. The memory is configured to store capability data corresponding to a set of stations. The processor is configured to select, based at least in part on the capability data, one of a multi-user multiple-input multiple-output (MU-MIMO) mode or an orthogonal frequency-division multiple access (OFDMA) mode for wireless communication with a subset of the set of stations. The transceiver is configured to wirelessly communicate with the subset in the selected one of the MU-MIMO mode or the OFDMA mode.

Abstract: Apparatuses and methods for separately scheduling and grouping multiple wireless local area network (WLAN) users are disclosed. The apparatuses and methods include scheduling, at an access point (AP), multiple wireless stations (STAs) associated with the AP; identifying based at least in part on the ranking, a group of STAs from the STAs for transmission of data over a single orthogonal frequency-division multiple access (OFDMA) frame in a WLAN; and providing information resulting from scheduling the STAs and identifying the group of STAs to at least one of the STAs. In others aspects, the apparatuses and methods include receiving at an STA from an AP, scheduling information for a group of STAs including the STA; and transmitting based on the scheduling information, data over an OFDMA frame in an unlicensed or shared spectrum, the STA having a traffic load different from the traffic load of the at least one additional STA.
