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.

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： A wireless terminal receives peer to peer resource control information from a base station. The peer to peer resource control information is used by the wireless terminal in a peer to peer network to control transmission scheduling and/or resource utilization. The base station sends the control signals at a first rate which is slower than the rate at which wireless terminals make transmission decisions for traffic slots. During the intervals between receipt of the base station control signals, wireless terminals make transmission decisions with regard to multiple traffic segments. The decisions are also influenced based on peer to peer signaling occurring between the wireless terminals in the network for each traffic slot. Resource utilization feedback information is provided from the wireless terminal to the base station. Based on the feedback information the base station updates the resource utilization control information and sends updated resource utilization control signals to the wireless terminals.

摘要： Methods and apparatus for determining whether two or more communications devices, e.g., wireless terminals, in a communications system should communicate using direct peer to peer communications or via one or more infrastructure elements, e.g., base stations, are described. The determination whether a given pair of communications devices should communicate using direct peer to peer communications, rather than via the infrastructure element(s), is determined by a control device. The control device instructs various wireless terminals to make various signal measurements and/or transmit signals to be measured. Based on the signal measurements the control device estimates interference caused by the direct peer to peer link to the existing communications devices, the direct peer to peer link channel quality and/or interference caused to such a direct peer to peer link by existing communications devices which are communicating using peer to peer signaling and makes a mode decision based on such information.

The peer-to-peer data resources include a first set of peer-to-peer resources with a first bandwidth and a second set of peer-to-peer resources with a second bandwidth greater than the first bandwidth. The first set of peer-to-peer resources is parallel in time with the non peer-to-peer resources. In addition, the method includes estimating a signal quality for a data transmission on the peer-to-peer data resources. Furthermore, the method includes determining whether to send the data transmission in one of the first set of peer-to-peer resources or the second set of peer-to-peer resources based on the estimated signal quality.
