    摘要： A method of operating a wireless device is provided in which the wireless device determines to use one grouping of peer discovery resources of a plurality of groupings of peer discovery resources based on one of a path loss or a distance to a base station. The plurality of groupings include a first grouping of resources having a first plurality of identical subsets of resources and a second grouping of resources having a second plurality of identical subsets of resources. Each of the first plurality of identical subsets of resources extends over at least one of a different time period or a different number of subcarriers than each of the second plurality of identical subsets of resources. The wireless device transmits a peer discovery signal on one subset of the identical subsets of said one grouping of peer discovery resources.

    摘要： A method of operating a first wireless device includes receiving a grant from a base station for peer-to-peer communication with a second wireless device using time-frequency resources utilized by a third wireless device for WWAN communication with the base station. In addition, the method includes receiving a transmit power for the peer-to-peer communication with the grant. The transmit power is determined based on an interference that can be caused to transmissions received by the base station from the third wireless device. Furthermore, the method includes communicating with the second wireless device at a power less than or equal to the received transmit power using peer-to-peer communication on the time-frequency resources.

    摘要： To maintain a synchronized wireless peer group, timing signals may be periodically transmitted by one or more devices in the wireless peer group. These periodic timing signals may be transmitted by different wireless devices in the peer group, distributing (sharing) the transmit power burden among the different wireless devices, increasing the useful operation time of the individual wireless devices. Similarly, the wireless peer group may monitor for timing signals received from devices that are not part of the wireless peer group. This monitoring burden may also be distributed (shared) among the devices in the peer group allowing for a greater sleep time for individual wireless devices, increasing the useful operation time of the individual wireless devices.

    摘要： Various methods and apparatus are directed to collision detection and/or avoidance regarding peer to peer connection identifiers. A wireless communications device broadcasts a signal indicating its acquired connection identifier in one of two alternative blocks. A base station monitors peer to peer signaling in its coverage area and tracks the usage of peer to peer connection identifiers by pairs of devices. The base station detects when multiple pairs of devices are using the same peer to peer connection identifier. The base station provides assistance to the peer to peer network to avoid a collision or facilitate rapid collision detection by the peer to peer devices. In one approach the base station sends an instruction for a connection to switch its connection identifier. In another approach the base station sends a connection a message to bias its selection as to which of the two alternative blocks to use for transmission.
