    Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system through efficient transmissions and acknowledgements of information between an AP and a station. The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency.

    Abstract: A wake-up radio is configured to scan for transmissions while the radio receiver is in sleep mode. The wake-up radio detects incoming RF transmissions intended for the radio receiver by analyzing data frame characteristics in an incoming RF transmission. The data frame characteristics may contain a signature code that is unique to the radio receiver. The signature code may be based on the time duration of a sequence of orthogonal frequency division multiplex (OFDM) symbols received in a clear to send to self (CTS2S) transmission or a time duration of short interframe spaces (SIFS) used to transmit the data frames.

    Abstract: A method of performing transmission from an access point (AP) in a wireless communication system provides transmission setting adjustment after sounding. In this method, stations associated with the AP and having transmission data can be identified. Transmission to those stations can be performed using a predetermined transmission setting. For a first transmission after a sounding, the predetermined transmission setting can be boosted. For any transmission other than the first transmission after the sounding, a current or adjusted transmission setting can be used based on a detected PER during transmission. An adjusted transmission setting can be an MCS rate, a user-level (SU-BF, 2U-MIMO, or 3U-MIMO), or an aggregated MAC protocol data unit (AMPDU) aggregation level. A single transmission setting or a combination of settings can be used. The method can be used with any transmission setting(s), including those mapped from the Signal to Interference and Noise Ratio (SINR).

    Abstract: A data source sends a synchronization signal and information to several data sinks that use the synchronization signal and a specified parameter to determine when to process the information. The data source and data sinks may comprise wireless nodes such as, for example, a wireless audio source that sends multi-channel data to a pair of wireless earpieces. The wireless earpieces use the synchronization signal and a latency interval to determine the appropriate time to output audio based on the audio channels.

    Abstract: An access point determines the buffered data for each station of a plurality of stations in a BSS and groups the stations with similar station characteristics. The transmission time to the stations in a group can be apportioned. The groups can be ordered based on station characteristics and a transmission history. A sounding for a group can be performed based on the order. The MU-MIMO transmission for the group can be performed until a first condition is met. If the first condition is met, then the sounding and the MU-MIMO transmission for a next group can be performed, according to the order, until a second condition is met. The first condition can include an apportioned transmission time having expired and/or the buffers for the group being flushed. The second condition can include new data having been buffered by the AP and/or all buffered data having been transmitted.
