Method and apparatus for establishing and maintaining peer-to-peer (P2P) communication on unlicensed spectrum

摘要

Techniques for establishing and maintaining peer-to-peer (P2P) communication are described. In an aspect, P2P communication on an unlicensed spectrum may be established and maintained with network assistance. In one design, a user equipment (UE) may communicate with a wide area network (WAN) to establish P2P communication with at least one other UE on a first frequency band that is not licensed to the WAN. For example, the UE may receive an assignment of at least one frequency channel in the first frequency band for P2P communication. The UE may then communicate peer-to-peer with the other UE(s) on the at least one frequency channel. The UE may also communicate with the WAN to maintain P2P communication with the other UE(s), e.g., to switch to another frequency channel if necessary.

主权项

1. A method for wireless communication, comprising:
receiving a proximity detection signal by a first user equipment (UE) from at least one other UE; sending a request to a wide area network (WAN) by the first UE to establish peer-to-peer (P2P) communication with the at least one other UE on a first frequency band not licensed to the WAN, in response to receiving the proximity detection signal from the at least one other UE; receiving a query from the WAN for determining the capabilities of the first UE, the capabilities comprising whether the first UE is able to detect other UEs on the first frequency band; determining at least a first frequency channel in the first frequency band available for P2P communication, based on the capabilities of the first UE; and communicating peer-to-peer with the at least one other UE on the first frequency band by the first UE.
