摘要： A method of operating a wireless device includes determining an energy on each of a plurality of resources for broadcasting CIDs, sending information to a base station based on the determined energy for each of the CIDs, and receiving a CID from the base station. The received CID is one of the CIDs determined based on the information. A method of wireless communication includes receiving first information about a first plurality of CIDs from a first wireless device, receiving second information about a second plurality of CIDs from a second wireless device, comparing the first information and the second information to determine a subset of CIDs based on the first plurality of CIDs and the second plurality of CIDs, selecting a CID based on the subset of CIDs, and sending the selected CID to at least one of the first wireless device or the second wireless device.

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 wireless communications system supports both cellular communications and direct peer to peer communications. The cellular communications use FDD downlink and uplink bands for control and traffic signaling. An access point employs control over direct peer to peer communications. Peer to peer mode control signals from the access point are transmitted to wireless terminals using the FDD cellular downlink band. Peer to peer mode control signals from wireless terminals are transmitted to an access point using the FDD cellular uplink band. Peer to peer traffic signals between wireless terminals are communicated using a TDD band. In one embodiment, the access point communicates priority information to peer to peer network wireless terminals, and the wireless terminals make peer to peer traffic transmission decisions in a decentralized manner using the received priority information. In another embodiment, the access point directly schedules peer to peer traffic in the peer to peer network.
