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： Various embodiments relate to wireless communications, and more particularly, to methods and apparatus for authorizing use of spectrum, e.g. , through the issuance of spectrum access keys, and/or preventing or discouraging the unauthorized use of licensed spectrum. Peer to peer wireless communications between authorized users of licensed spectrum may involve scrambling/descrambling of information communicated between authorized devices. In some embodiments air interface timing and/or other information received from a second device, e.g. , a beacon or GPS transmitter, is incorporated into a computation of a pseudo-random bit sequence which is also computed based on a spectrum access key communicated to authorized spectrum users. In some embodiments authorized peer to peer devices scramble communicated information based on the generated pseudo random bit sequence thereby preventing or discouraging communication with devices which are not authorized to use the spectrum and lack a spectrum access key used to generate the pseudo random bit sequence.

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： 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： 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： Techniques for transmitting signals on shared resources in a manner to detect and/or combat collision are described. In an aspect, a terminal may transmit a signal on a subset of resource elements in a resource block, and at least one null resource element with no signal may be used to detect for collision of the signal. In another aspect, different terminals may simultaneously transmit their signals on different subsets of resource elements in a resource block. These different subsets of resource elements may be pseudo-randomly selected to randomize interference. In one design, a terminal may determine a resource block to use for transmission of a signal, select a subset of the resource elements in the resource block, and transmit the signal on the selected resource elements, e.g., to at least one other terminal for peer-to-peer communication. The signal may be a peer discovery signal, a paging signal, etc.
