Abstract
Techniques for supporting peer-to-peer (P2P) communication and wide area network (WAN) communication are disclosed. In one aspect, P2P communication may be supported on an uplink spectrum. A user equipment (UE) may communicate (i) with a base station on both a downlink spectrum and an uplink spectrum for WAN communication and (ii) with another UE on only the uplink spectrum for P2P communication. In another aspect, P2P communication may be supported by time division multiplexing the downlink and uplink (or transmit and receive links) for two UEs. In yet another aspect, WAN communication and P2P communication may be time division multiplexed, so that both can be concurrently supported by a UE. In yet another aspect, transmission gaps may be provided between WAN transmissions and P2P transmissions in order to avoid interference between these transmissions.
