    摘要: Methods and apparatus for supporting multi-hop peer discovery in peer-to-peer wireless networks are disclosed. One method supports multi-hop peer discovery using a first peer having a first unique identification code. The method includes decoding a second peer discovery signal to obtain a second unique identification code and a second local identification code of a second peer received during a peer-to-peer discovery channel, determining whether to select the second peer based on a predetermined criterion; and transmitting a first peer discovery signal having the first unique identification code, the second local identification code and a hop count when the predetermined criterion is satisfied.

    摘要: Techniques for transmitting information in a long term evolution (LTE) wireless communication network are disclosed. A base station may receive a first user equipment (UE) expression and first UE location information of a UE seeking peers. The base station may also receive a second UE expression and second UE location information of at least one of the peers. In accordance with the first and second UE expressions and the first and second UE location information, the base station may match ones of the peers proximate to the UE. The base station may transmit, using a data exchange efficiency technique, information to alert the UE to the presence of the peers. This transmission may comprise wide area network (WAN)-specific signaling.

    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: A wireless terminal detects timing signals from different local timing signal sources. The wireless terminal selects from the plurality of detected timing signal sources two timing signal sources in accordance with a predetermined timing signal source priority ordering. In some embodiments, the wireless terminal intentionally selects two timing signal sources which are not synchronized with respect to one another. The wireless terminal determines a first set of peer communications time intervals corresponding to a first selected timing signal source and a second set of peer communications time intervals corresponding to a second selected timing signal source. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the first set of peer communications time intervals. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the second set of peer communications time intervals.

    摘要: Methods and apparatus for determining band availability and/or allocating one or more frequency bands to a communications device for wireless communications are described. In different locations and/or at different times different frequency bands, e.g., band corresponding to unused TV channels, may be available for allocation. Various described methods and apparatus are well suited for supporting local peer to peer networks in an environment in which a plurality of different technologies are supported. A centralized control device determines and allocates a frequency band to a wireless terminal for use at a given location and at a given time, e.g., for peer to peer communications using a particular technology supported by the wireless terminal. The centralized control device uses database information and information received from a plurality of wireless terminals in making frequency band allocation decisions, performing load balancing, and/or performing interference management.

    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.
