摘要： A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling distributed frequency synchronization based on a fastest node clock rate. In one example, a first UE is equipped to determine that a fastest clock rate is faster than an internal clock rate of the first UE by more than a first positive offset, and adjust the internal clock rate based on the determined fastest clock rate. In an aspect, the fastest clock rate is associated with a second UE of one or more other UEs from which synchronization signals may be received. In another example, a UE is equipped to obtain GPS based timing information, adjust an internal clock rate based on the GPS based timing information, and transmit a synchronization signal at an artificially earlier time in comparison to a scheduled time of transmission associated with the adjusted internal clock rate.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in a wireless communications system are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. An individual wireless terminal corresponding to a peer to peer connection which desires to communicate traffic signals makes a receiver yielding decision. The receiver yielding decision, in some embodiments, includes comparing a link quality estimate corresponding to its own link, to a dynamically generated receiver yielding threshold. The dynamically generated receiver yielding threshold is determined based on at least one of: quality of service information corresponding to its own link and historical link quality information corresponding to its own link.

摘要： Methods and apparatus for using different frequency bands are described. In some embodiments a first frequency band which is a licensed spectrum frequency band is used for peer discovery, device authentication, session establishment between peer devices and/or supporting an ongoing communications through control signaling. When available, a second frequency band, e.g., an unlicensed public frequency band is used for communicating data while the communications session is maintained using one or more control signals communicated in the first frequency band. Data and control signaling may be performed on a time division basis during a time period in which data is communicated.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus generates a codeword, determines at least one puncture to the codeword based on allowing a legacy receiver to decode the codeword without knowledge of the at least one puncture, replaces each of the at least one puncture with a pilot, and transmits the codeword. The apparatus may also generate an IEEE 802.11 codeword having pilots in a first set of subcarriers, and puncture the codeword with additional pilots unknown to a legacy receiver in a second set of subcarriers. Accordingly, when an original set of pilot symbols is insufficient or inappropriately placed in a resource structure, a codeword may be transmitted with a new pilot structure capable of being decoded by legacy receivers not aware of the new pilot structure.

摘要： Methods and apparatus for use in a wireless system are described where initiation of packet transmission is constrained in accordance to control actual packet transmission in a manner that reduces contention and possible collisions beyond that provided by lower layer resource contention mechanisms, e.g., 802.11 carrier sensing and/or transmission back-off timing mechanisms. Through higher level, e.g., MAC constraints, on packet transmission initiation, an air interface which employs carrier sensing can be used and controlled in a manner which reduces collisions and interference in applications where small packets, e.g., packets which can be transmitted in a fraction of the maximum permitted transmission time. The methods allow small packets in such systems to be transmitted on a periodic or semi-periodic basis in many cases.

摘要： A wireless microphone receiver is used to control transmission power and/or channel configuration of wireless microphones which communicate audio data to the wireless microphone receiver. In some embodiments the wireless microphone receiver searches for available channels, e.g., on a periodic or other basis. Based on wireless microphone receiver loading and interference considerations, channel availability may be determined and channel assignments are made. In some embodiments channel assignments are made based on wireless microphone battery status. Channel assignments to wireless microphones are communicated via a control channel. In addition to channel assignments, wireless microphone transmitter power can be controlled by the wireless microphone receiver. Commands to increase or decrease transmission power may occur as channel conditions change and/or on a recurring periodic basis. The rate of power control transmission may be relatively infrequent, e.g., a second apart in some embodiments, given that wireless microphones tend to be relatively stationary during use.

摘要： Methods and apparatus for controlling switching between resources and/or communicating resource change information in a wireless communications system are described. Various methods and apparatus are well suited for use in a decentralized wireless communications network, such as a decentralized peer to peer wireless network, where an individual communications device self allocates resources and makes resource switching decisions. A first communications device may decide that there is a need to switch from the first communications resource corresponding to a first identifier to a second communications resource corresponding to a second identifier, e.g., because of interference. The first communications device generates and transmits a broadcast change signal indicating a change from the first communications resource associated with the first identifier to a second communications resource associated with the second identifier. In some embodiments, the resource change signal is transmitted on at least one of the first and second communications resources.

摘要： Methods and apparatus related to peer/network/service discovery in a mobile wireless system, e.g., an ad hoc peer-to-peer network are described. Transmission of discovery information, e.g., upper layer discovery information, is divided into a number of portions to be transmitted separately over time. Transmission of the individual portions is structured so as to enable flexibility in the frequency of the peer discovery transmissions as well as the monitoring of such transmissions. Various embodiments facilitate rapid discovery and/or secure discovery, e.g., selective discovery by trusted peers.
