Configuration of user equipment for peer-to-peer communication

摘要

Configuring a peer-to-peer (P2P) link in a multi-access wireless network includes receiving P2P configuration information from a base station at a UE supporting P2P communication. The first UE communicates directly with a second UE based on the P2P configuration information received from the base station. The first UE may send a configuration request message to the base station, and receive a responsive configuration message with the P2P configuration information from the base station, which messages may be Radio Resource Control (RRC) messages supporting P2P. In the alternative, the P2P configuration information may be provided in a system information block (SIB) broadcast by the base station. The P2P configuration information may indicate allocation of physical layer or Medium Access Control resources, or both allocated for P2P communication, and other information.

主权项

1. A method for wireless communication, comprising:
receiving peer-to-peer (P2P) configuration information from a base station at a first user equipment (UE), the P2P configuration information supporting P2P communication for UEs within coverage of the base station based on Evolved Universal Terrestrial Radio Access (E-UTRA) radio access technology without identifying the UEs; performing peer discovery by the first UE to detect a second UE, the peer discovery comprising detecting a peer discovery code on a proximity detection signal transmitted by the second UE advertising its availability for P2P communication; and communicating directly with the second UE by the first UE based on the P2P configuration information, wherein receiving the P2P configuration information comprises receiving at least one system information block (SIB) broadcast by the base station, and obtaining the P2P configuration information from the at least one SIB.
