摘要： A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.

摘要： Methods and apparatus for supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.

摘要： Non-coherent modulation is used to communicate coding information via pilot signals using a first subset of resources, and coherent modulation is used to generate data signals. This allows for a stronger global code while keeping individual signaling complexity low. First and second communications devices communicate information using a set of communications resources. By performing non-coherent demodulation on pilot signals received on a first subset of said set of communications resources coding information is recovered. First and second channel estimates are generated from the pilot signals received on the first subset of said communications resources. Coherent demodulation is performed on data signals received on a second subset of said set of communications resources using said first and second channel estimates and said coding information to recover information communicated by said first communications device and to recover separate information communicated by said second communications device.

摘要： Techniques for performing automatic gain control (AGC) at a terminal in a wireless communication network are described. In an aspect, the terminal may use different receiver gain settings to receive different types of signals in different time intervals. The terminal may determine a receiver gain setting for each signal type and may use the receiver gain setting to receive signals of that signal type. In another aspect, the terminal may determine a receiver gain setting for a future time interval based on received power levels for peer terminals expected to transmit in that time interval. The terminal may measure received power levels of signals received from a plurality of terminals. The terminal may determine a set of terminals expected to transmit in the future time interval and may determine the receiver gain setting for the future time interval based on the measured received power levels for the set of terminals.

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： 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.
摘要翻译：无线麦克风接收器用于控制将音频数据传送到无线麦克风接收器的无线麦克风的传输功率和/或信道配置。在一些实施例中，无线麦克风接收器例如在周期性或其他基础上搜索可用信道。基于无线麦克风接收器负载和干扰考虑，可以确定信道可用性并进行信道分配。在一些实施例中，基于无线麦克风电池状态进行信道分配。无线麦克风的信道分配通过控制信道进行通信。除了通道分配之外，无线麦克风发射器的功率可以由无线麦克风接收器控制。随着信道条件的改变和/或周期性重复发生，可能会发生增加或减少发射功率的命令。考虑到无线麦克风在使用期间倾向于相对固定，功率控制传输的速率可能相对不频繁，例如在一些实施例中相隔一秒。

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.
