摘要： Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.

摘要： A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which a first signal is generated for transmission to a wireless node to enable the wireless node to determine a first preferred beam pattern. A second preferred beam pattern is determined from a second signal received from the wireless node. The apparatus communicates with the wireless node through at least one of the first or second preferred beam pattern.

摘要： A clustering based load adaptive sleeping protocol for ad hoc networks includes a plurality of nodes forming a cluster, where the nodes in the cluster are partitioned into n groups. This partitioning is performed based on the node ID (e.g. node_id modulo n). The cluster head transmits a beacon at fixed intervals. The beacon interval is divided into N slots, where N is a multiple of n. Node sleep/activation times are synchronized to the beacon interval slots. The node's group number is used to determine the slots within a beacon interval that a node begins it s sleep cycle. Therefore, no additional signaling is required between nodes to indicate sleep patterns. The sleeping time of each node may be increased when extended periods of inactivity are detected according to an adaptive procedure.
