摘要： Aspects describe different multiple antenna techniques that can be utilized in a peer-to-peer network based on a network congestion level. A MIMO scheme where a transmitter sends to a receiver multiple spatial streams at substantially the same time in the same traffic segment can be utilized when network congestion level is low. A receiver beam forming scheme where transmitter sends a single stream in a traffic segment and receiver uses multiple receive antennas to maximize signal to noise ratio can be utilized when network congestion level is high. The connection pair (transmitter and receiver) occupy more control resources in the MIMO scheme than the receiver beam forming scheme. The decision related to which technique to utilize can be made at about the same time as a communication is initiated. Further, if network conditions change during a communication, the antenna technique that is utilized can be switched to a different technique during the communication exchange.

摘要： Methods and apparatus related to packet fragmentation and reconstruction are described. A sequence of bits is generated including at least one header and at least partial packet payload prior to a determination of the actual data rate to be used in a communications segment. In some embodiments, the generated sequence of bits corresponds to a prepared information bit stream for a best case scenario in which the highest data rate is selected for segment. Various embodiments allow for the selection of the data rate to be used for the communications segment to be delayed until just prior to the transmission. Thus the selection of the data rate for the communications segment, and thus the segment capacity, can be based on more current channel condition information than would otherwise be possible if the communications device needed to know the data rate for the segment before performing header and packet fragmentation operations.

摘要： Base station assisted peer to peer discovery methods are described. A wireless terminal communicates peer discovery expression information to a base station and information identifying a peer discovery resource that it intends to use but which may also be used by other devices. The base station associates the peer discovery expression and peer discovery resource with an index value to be communicated on the peer discovery resource. The base station transmits the peer discovery expression and information associating the peer discovery expression with the peer discovery resource and the index value. The wireless terminal transmits the index value on the peer discovery resource. A wireless terminal receiving the index value determines the peer discovery expression being communicated using information from the base station. Use of different indexes allows multiple devices to use the same discovery resource.
