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: Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes receiving one or more synchronization messages, each synchronization message having timing information and a cluster identifier, the timing information comprising anchor timing information, the cluster identifier being the same value as a cluster identifier of the apparatus. The method further includes determining whether a difference between a time value when a received synchronization message last received anchor timing information and a time value maintained for the apparatus is greater than a threshold. The method further includes discarding the received synchronization message if the difference exceeds the threshold.

Abstract: Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for determining at least one of a time for exiting and a time for entering a low power sleep mode to utilize a discovery window is provided. The method includes determining an earliest possible start time of a discovery window according to a clock at the first device. The method further includes transitioning from the low power sleep mode to a higher power active mode approximately at the determined earliest possible start time, wherein the determined earliest possible start time is based at least in part on a clock drift value associated with the first device and a clock drift value associated with a second device of the wireless network.

Abstract: Methods, devices, and computer program products communicating discovery information in a wireless neighborhood aware network (NAN). One method includes receiving, at a first wireless device, a message from a neighboring wireless device. The message includes a data structure indicative of discovered device identifiers. The method further includes determining whether the data structure indicates an identifier of the first wireless device. The method further includes transmitting a message including the identifier of the first wireless device when the data structure does not indicate the identifier of the first wireless device.

Abstract: A user equipment (UE) uses information regarding the timing of scheduling mobile wireless services (MWS) RAT communications to improve MWS and wireless network connectivity (WCN) radio access technology coexistence. To allow sufficient time for an uplink grant to be received by the UE in advance of the scheduled uplink time, an uplink grant may be sent in advance of the scheduled uplink time. In some instances, the UE may receive an indication of scheduled uplink time of the MWS RAT via a physical layer communication. The UE may schedule communications of the WCN RAT based at least in part on the indication of future activity.

Abstract: In a wireless communication system including a transmitter device and a receiver device, the receiver device may be configured to awake from a low power mode to receive beacons from the transmitter device. The receiver device may awaken an early reception interval prior to the beacon arrival time determined by the local clocks to account for inaccuracies in the local clocks and the transmitter clock. The early reception interval may be dynamically adjusted based upon an estimation of the clock errors to minimize the early reception interval.
