摘要： Techniques for transmitting signals using time hopping or time and frequency hopping are described. In one design, a terminal selects different slots to use for transmission in multiple frames with time hopping. Each frame includes multiple slots, and each slot covers a particular time duration. The selected slots are at different time locations in the multiple frames. In another design, a terminal selects different resource units to use for transmission in multiple frames with time and frequency hopping. The selected resource units are at different time and frequency locations in the multiple frames. For both designs, the terminal sends a signal (e.g., a peer discovery signal) in the selected slots or resource units in the multiple frames. The terminal may detect for signals (e.g., peer discovery signals) from other terminals in slots not used for transmission by the terminal.

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.

摘要： Methods and apparatus supporting enhanced discovery operations in peer to peer networks are described. Peer discovery, based on direct peer to peer discovery between two mobile nodes can be somewhat limited, e.g., due to power limitations, processing power, and/or channel conditions. An access point, e.g., base station, monitors for and receives peer discovery signals conveying a set of identifiers from a wireless communications device. The access point retransmits at least one identifier in the set in a wireless peer to peer communications channel. Thus the access point effectively extends the peer discovery range for wireless communications devices utilizing the peer to peer network. Wireless communications devices can monitor for and recover the rebroadcast peer discovery signals from access points. Thus, via access point signaling a wireless communications device can be made situationally aware of other devices of interest which would be otherwise outside its discovery detection range.
摘要翻译：描述了支持对等网络中增强发现操作的方法和装置。基于两个移动节点之间的直接对等点发现的对等体发现可以受到一些限制，例如由于功率限制，处理能力和/或信道条件。接入点，例如基站，监视和接收从无线通信设备传送一组标识符的对等体发现信号。接入点在无线对等通信信道中重发集合中的至少一个标识符。因此，接入点有效地扩展了利用对等网络的无线通信设备的对等体发现范围。无线通信设备可以监视和恢复来自接入点的重播对等体发现信号。因此，通过接入点信令，可以使无线通信设备在情境上意识到其他在其发现检测范围之外的感兴趣的设备。

摘要： Methods and apparatus well suited for efficiently communicating small amounts of information relatively frequently in a wireless communications system are described. An uplink timing frequency structure for an access point includes a set of dedicated uplink communications resources, e.g., expression advertisement interval air link resources. Different ones of the set of dedicated uplink communications resources correspond to different individual wireless communications devices currently registered with the access point. In the downlink timing frequency structure for the access point there are dedicated downlink broadcast communications resources, e.g., expression broadcast interval air link resources and neighbor expression broadcast interval air link resources. Information received on dedicated uplink air link resources is echoed back or selectively echoed back on the dedicated downlink air link resources. Wireless communications devices monitor downlink dedicated air link resources to recover expression information being communicated by other wireless communications devices in its local vicinity.

摘要： Techniques for performing automatic gain control (AGC) at a receiver are described. The receiver may receive an OFDM-based symbol composed of a cyclic prefix and a useful portion. The receiver may scale the OFDM-based symbol with an initial receiver gain, adjust the initial receiver gain based on the cyclic prefix, apply the adjusted receiver gain prior to the useful portion, and process the useful portion to recover at least one signal sent by at least one transmitter. The receiver may select the initial receiver gain, e.g., based on a predicted received power level for the at least one transmitter, a pattern of different receiver gains, etc. The receiver may apply the initial receiver gain at the start of the OFDM-based symbol. The receiver may measure the power of a set of samples in the cyclic prefix and may adjust the receiver gain based on the measured power and a target power.

摘要： Methods and apparatus for efficiently communicating small amounts of information relatively frequently in a wireless communications system are described. An access point's uplink timing frequency structure includes a set of dedicated uplink communications resources, e.g., expression advertisement interval air link resources, which may be in addition to regular traffic channel resources. The set of dedicated uplink communications resources comprises a small fraction of the total uplink communications resources. An individual one of the set of dedicated uplink communications resources can carry a small amount of information bits. An expression advertisement interval occurs relatively frequently. A wireless communications device, registered with the access point, is allocated one of the set of dedicated uplink resources. The wireless communications device can transmit information using its allocated resource in both a sleep state and an active state.
