Abstract: Coordination and synchronization is performed between two or more wireless network managers (e.g., access points (APs)). A first wireless network manager supports first communications with first other wireless communication devices, and a second wireless network manager supports second communications with those first and/or second other wirelessly case devices. The first and second wireless network managers also support communications with one another to coordinate the first and second communications supported with the first and/or second other wireless communication devices. Examples of coordination include selection of which other wireless communication devices are serviced or in communication with which of the first and second wireless network managers, selection of operational parameters (e.g., modulation coding set (MCS), beamforming, frequency band assignment, channel assignment, scheduling information, transmit power, etc.) for the first and second wireless communication devices, synchronization to a common clock (e.g., using timing synchronization function (TSF)).

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 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.

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 discovered using probe request. A source device that intends to transmit one or more frames to a destination device transmits the probe request to request a probe response from one or more potential relay devices. A relay device transmits a probe response to the source device when the relay device may operate to forward the one or more frames from the source device to the destination device. The relay device employs one or more considerations to determine its eligibility to serve as relay for the source and destination devices. The source device selects one of the potential relay devices based on their provided probe responses. The source device may select an optimal relay device based upon two or more received probe responses.

Abstract: A wireless communication device is implemented to include a communication interface and a processor. The processor is configured to process communications associated with the other wireless communication devices within the wireless communication system to determine one or more traffic characteristics of those communications as well as one or more class characteristics of the other wireless communication devices. The processor is configured to classify the communications into one or more access categories based on the one or more traffic characteristics and is configured to classify the other devices into one or more device class categories based on the one or more class characteristics. The processor is then configured to generate one or more channel access control signals based on these classifications. The communication interface of the device is configured to transmit the one or more channel access control signals to one or more of the other devices.

Abstract: A signaling protocol allows for speed frame exchange between different wireless communication devices within single user, multiple user, multiple access, and/or MIMO wireless communication system. A listening wireless communication device analyzes state of speed frame indicator bits within frames transmitted from a first other wireless communication device to determine the entire radio frame exchanges between that first other wireless communication device and a second other wireless communication device. The second other wireless communication device may be a hidden node relative to the listening wireless communication device such that all or less than all transmissions from the hidden node are received by the listening device. The listening wireless communication device determines the status of the communication medium (e.g., the air in the context of a wireless communication system), so that it can transmit successfully without interfering with any ongoing communications between the first and second other wireless communication devices.
