Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to bandwidth dependent carrier sensing for orthogonal frequency division multiple access (OFDMA). One example apparatus for wireless communications generally includes a first interface for obtaining at least a first frame with an indication of a time duration during which at least one bandwidth channel is occupied; a processing system configured to track, based at least in part on the indicated duration, availability of time and one or more resources on a plurality of bandwidth channels including the at least one bandwidth channel and to determine whether resources are available to transmit at least a second frame, based on the tracked availability; and a second interface for outputting the second frame for transmission if the determination indicates resources are available.

Abstract: Certain aspects of the present disclosure relate to station backoff behavior in uplink (UL) multiple user (MU) operations. Certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus generally includes a processing system configured to generate an unsolicited single user (SU) frame for transmission to an access point (AP) while the apparatus is configured to communicate with the AP via MU transmissions and a transmit interface configured to output the unsolicited SU frame for transmission. Certain aspects of the present disclosure provide another apparatus for wireless communications. The apparatus generally includes a processing system configured to contend for access to a medium by generating a first frame to trigger MU transmissions from a plurality of apparatuses and a transmit interface configured to output the first frame for transmission.

Abstract: Methods and apparatuses are described for asynchronous communications in a sensor network. An indication of a receiving opportunity can be transmitted by a sensor device. The sensor device can then provide the receiving opportunity based at least in part on transmitting the indication, and disable communication resources at the sensor device for a duration of a sleep time following the receiving opportunity. An upstream node can generate information for communicating to a sensor device, receive the indication of the receiving opportunity from the sensor device, and transmit the information to the sensor device during the receiving opportunity based at least in part on receiving the indication.

Abstract: Apparatus and method are provided for performing asynchronous discovery among multiple peers in a wireless peer-to-peer (P2P) network. In an aspect of the disclosure, a peer selects a duty cycle C corresponding to a probability that the peer is in either a scanning state or an advertising state, rather than a sleeping state, wherein the duty cycle C is selected in accordance with a power consumption of the peer. The peer also selects a first probability Pt for being in the advertising state, and performs an asynchronous discovery protocol in accordance with the duty cycle C and the first probability Pt.
