摘要： 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.

摘要： 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.

摘要： Systems and methods are provided for enhancing the concurrency of a wireless device operating in multiple network contexts. By identifying opportunity instants that may exist within the normal exchange of information by a device having a single physical transceiver in a first network context, tasks for a second network context may be performed using the transceiver with minimal impact on performance related to the first network context and preferably in complete transparence to the first network context.

摘要： 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 network is provided. The method includes determining first and second contention windows. The first contention window begins earlier than the second contention window. The method further includes beginning a first carrier sense multiple access (CSMA) countdown at the start of the first contention window. The method further includes beginning a second CSMA countdown when the first CSMA countdown does not end before the start of the second contention window. The method further includes transmitting the prepared frame at a time of the first CSMA countdown ending or the second CSMA countdown ending, whichever is earlier.
