Claim Text:
1. A method of wireless communication, comprising: determining, at a user equipment (UE) a set of resources for sending requests for peer discovery signals and receiving peer discovery signal responses; sending a transmission, from the UE, in a first time slot of the set of resources requesting a peer discovery signal, wherein the UE indicates whether the transmission is a unicast request or a multicast request by selecting and including a first pilot sequence in the transmission when the transmission is a unicast request and a second pilot sequence in the transmission when the transmission is a multicast request, wherein the first pilot sequence is different from the second pilot sequence, and wherein the first pilot sequence is selected from a first subset of pilot sequences of a set of orthogonal pilot sequences and the second pilot sequence is selected from a second subset of pilot of sequences of the set of orthogonal pilot sequences; and receiving, at the UE, at least one peer discovery signal response in a second time slot of the set of resources based on the transmission, the second time slot being a next available time slot after the first time slot for sending requests for peer discovery signals and receiving peer discovery signal responses.
