Abstract: Methods, systems, and devices are described for wireless communication. A wireless device may identify an upcoming interference period, determine a receive end time based on when the interference period will begin to disrupt incoming messages, and transmit a scheduling outlook message to a transmitter to schedule around the interference in response to receiving a packet (request-to-send (RTS) or data). The wireless device may hash a receiver address (RA) associated with the packet exchange message such as a clear-to-send message or a block acknowledgement to make room for the scheduling outlook message. An example scheduling outlook field (in the place of the full RA field) may include a shortened RA, a number of supported spatial streams, a supported bandwidth, a set of tone allocation units (TAUs), a receive end time (or receive duration), and an interference level.

Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device determines when a first transceiver chain of the wireless device is to receive a first data signal. The wireless device then transmits a second data signal via a second transceiver chain of the wireless device based at least in part on the determination. The wireless device further suspends the transmission of the second data signal in response to the determination that the first transceiver chain is to receive the first data signal.

Abstract: Methods, devices, and computer program products for collision management of wireless devices in a peer-to-peer network are described herein. In one aspect, a method of communicating via a wireless medium by a wireless communications apparatus within a neighborhood aware network is provided. The network is configured with periodic discovery windows, and sized for a maximum number of devices M. The method includes determining a discovery window interval K, the smallest integer greater than or equal to one, such that the probability that more than a threshold M devices will transmit during the same discovery window is less than a threshold probability P. The method further includes selecting a random or pseudo-random integer m in the range from 0 to K−1, deferring for at least m discovery windows after a previous interval K−1 has elapsed, and transmitting a discovery frame during the next discovery window after said deferring.

Abstract: A system and method are disclosed that reduce collisions on a wireless medium shared by devices associated with a wireless network, thereby improving throughput on the wireless medium. For some embodiments, a first device reserves access to the medium for a first interval, and then grants medium access to a second device for a remainder of the first interval. If the second device transmits data during the remainder of the first interval, medium access is maintained with the second device and then the second device is prevented from contending for medium access during a subsequent contention period. Otherwise, medium access is returned to the first device and the second device is allowed to contend for medium access during the contention period.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station. The AP may communicate with the station based on the modified uplink communication scheme

Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device receives a first data signal via a first transceiver chain while concurrently initiating a transmission of a second data signal via a second transceiver chain of the wireless device. The wireless device suspends updates to one or more tracking loops of the first transceiver chain in response to initiating the transmission of the second data signal. The updates to the one or more tracking loops may be suspended prior to transmitting the second set of data from the second transceiver chain. The wireless device may subsequently resume updates to the one or more tracking loops of the first transceiver chain after completing the transmission of the second data signal.

Abstract: Methods, systems, and devices are described for wireless communication at a wireless device having collocated radios employing different radio access technologies (RATs). For example, a second radio of the wireless device may receive a first scheduling message. The first scheduling message may include information relating to timing, priority, transmission power, and radio capabilities. Using this scheduling message, a determination of whether a first radio employing a first RAT and the second radio employing a second RAT can transmit in parallel may be made. A first transmission on the first radio may be coordinated with a second transmission on the second radio based on the determination of whether the first radio and the second radio can transmit in parallel. A number of data units may be aggregated into an aggregate frame to be transmitted by the second radio. The number of data units may be based on the scheduling message.
