Abstract: A method includes sending, from a first transmitter to a first receiver, a request to send (RTS) message associated with a first transmit opportunity (TXOP). The RTS message requests the first receiver to indicate whether reuse of the first TXOP is permitted. The method further includes receiving, at the first transmitter from the first receiver, a clear to send (CTS) message responsive to the RTS message.

Abstract: Aspects of the present disclosure provide techniques and apparatus for deferral based on basic service set identification (BSSID) information. According to certain aspects, a method for wireless communications is provided. The method generally includes receiving, on a shared access medium, a packet having at least one deferral-related parameter and deciding whether to defer transmission on the shared access medium based, at least in part, on the deferral-related parameter. Another method may generally include generating a packet comprising at least one deferral-related parameter to be used by another apparatus for deciding whether or not the other apparatus should defer transmitting on a shared access medium and providing the packet to the other apparatus.

Abstract: A slotted message access protocol can be implemented for transmitting messages in a communication network. A beacon period may be divided into multiple communication slots. A master network device may register a first client network device and provide registration information to the first client network device. The registration information may include one or more encryption keys to allow the first client network device to securely transmit messages in the communication network. The client network device may use an encryption key associated with a second client network device to decrypt messages received from the second client network device. Furthermore, the first client network device may use a contention-based communication slot to request allocation of contention-free communication slots for subsequent transmissions. The master network device may temporarily allocate contention-free communication slots to the client network device for a specified duration.

Abstract: A slotted message access protocol can be implemented for transmitting messages in a communication network. A beacon period may be divided into multiple communication slots. A master device may register a client device and provide registration information to allow the client device to operate in the communication network. The registration information may be determined based, at least in part, on a location of the client device in the communication network. As part of the registration information, contention-free communication slots may be assigned for use by the client device. Contention-based communication slots may also be assigned to a group of client devices. Messages may also be segmented depending on whether the message is transmitted in a contention-free or a contention-based communication slot. Furthermore, a relay device may be designated to retransmit a message (received from an original transmitting device) during a communication slot assigned to the original transmitting device.

Abstract: Channel reuse may be used so that multiple networks may communicate via a shared powerline communication (PLC) medium. In a PLC network that supports different transmission modes, channel reuse may be improved by determining signal performance metrics associated with the different transmission modes. A transmission mode may be selected to facilitate channel reuse of the PLC medium by the local network and neighbor network. A first device and a second device may belong to a local network that shares the PLC medium with a neighbor network. The transmission mode may be selected based on interference and signal measurements at one or more receivers of the second device. The transmission mode may be selected from a group comprising a 2-stream multi-input multi-output (MIMO) eigen-beamforming transmission mode, a 1-stream MIMO spot-beamforming transmission mode, and a 1-stream single-input-single-output (SISO) transmission mode.

Abstract: A method includes determining, based on a first packet error rate (PER) associated with a first communication data rate of data sent from a first electronic device to a second electronic device, a predicted second PER associated with a second communication data rate by increasing a value of the predicted second PER based on a first signal-to-noise ratio (SNR) sensitivity associated with the first communication data rate being less than a second SNR sensitivity associated with the second communication data rate or by decreasing the value of the predicted second PER based on the first SNR sensitivity being greater than the second SNR sensitivity. The method further includes selecting a communication data rate for communication from the first electronic device to the second electronic device based at least in part on the first PER and the predicted second PER.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.
