Abstract: Session recovery after network coordinator or AP restart for single user, multiple user, multiple access, and/or MIMO wireless communications. Restart or reset of a network coordinator (e.g., an access point (AP) or other network coordinator type device) may occur for various reasons (e.g., a power cycle or power failure, inadequate failover protection, scheduled or planned power outages such as for including network maintenance, software upgrades, etc.). Upon determination of network coordinator restarted or reset, a singular bit within a communication from the network coordinator indicates synchronization or not of the its timing synchronization function (TSF) (e.g., with other devices in the communication system, such as wireless stations (STAs), smart meter stations (SMSTAs), etc.). A given device (e.g., STA, SMSTA, etc.) can provide its current TSF to the network coordinator so that it can resynchronize, re-establish its scheduled for wake times of those devices (e.g., target wake times (TWTs)), etc.

Abstract: A wireless communication device is configured to generate frames based on any of a number of different frame formats for transmission to one or more other recipient wireless communication devices. The frame may be implemented to include data intended for two or more recipient devices. The device encodes first data intended for a first recipient device using first one or more coding parameters and encodes second data intended for a second recipient device using second one or more coding parameters. The manner by which the first and second data have been encoded is indicated within one or more other fields within the frames based on the selected frame format. In one example, a single preamble specifies the first and second one or more coding parameters. In another example, an initial preamble and one or more respective sub-preambles specify the first and second one or more coding parameters.

Abstract: A wireless communication device includes communication interface configured to receive and transmit signals and a processor configured to generate and process such signals. The communication interface of the wireless communication device is configured to receive a first signal from a first other wireless communication device, and the processor of the wireless communication device is configured to process the first signal to determine one or more concurrent transmission parameters. The processor of the wireless communication device is configured to generate the second signal based on the one or more concurrent transmission parameters and direct the communication interface to transmit the second signal to a second other wireless communication device during receipt of the first signal from the first other wireless communication device. The wireless communication device may be configured to make such concurrent transmissions based on one or more considerations such as the power level of the first signal.

Abstract: A relay receives a frame from a source, and based on state of a relayed frame bit within the frame, the relay selects an operational mode: implicit acknowledgement mode, first explicit acknowledgement mode, or second explicit acknowledgement mode. The relay sets the relayed frame bit in subsequent transmissions to indicate transmission opportunity (TXOP) control of the communication medium (e.g., whether under control of the relay or the source). The source may receive acknowledgement of the relay's successful receipt of the frame implicitly via the relay transmitting a relayed frame to the destination. Alternatively, the source may receive acknowledgement of the relay's successful receipt of the frame explicitly in a response frame from the relay. State of a more data bit in the frame receive from the source may indicate the source has one or more additional frames intended for the destination.

Abstract: A relay wireless communication device is implemented to perform buffer management and coordination with a source wireless communication device. A relay wireless communication device (generally, a relay) informs a source wireless communication device (source) of the status of memory therein to store messages intended for a destination wireless communication device (destination). For example, the source transmits information to the relay, which buffers information before forwarding it on to the destination. This buffering may be a function of the source having additional information intended for the relay and/or destination. The relay performs appropriate signaling, such as suspend transmission requests and resume transmission requests, to inform other devices in the system of its memory storage status (e.g., such as when having an actual or anticipated overflow). In one implementation, a suspend transmission request may be implemented by setting a particular bit within a communication from the relay to the source.
