Claim:
1. A method for communication between wireless devices using a peer discovery slot, the method comprising: receiving a first peer discovery signal, transmitted by a neighboring wireless device, through a plurality of peer discovery channels within a transmission slot of a first peer discovery period; receiving a first feedback signal, transmitted by the neighboring wireless device, through a plurality of response channels within a response slot of the first peer discovery period, wherein the first feedback signal is generated based on a peer discovery signal received by the neighboring wireless device; selecting a peer discovery channel among the plurality of peer discovery channels based on the received first peer discovery signal and the first feedback signal; transmitting a second peer discovery signal through the plurality of peer discovery channels within the transmission slot of a second peer discovery period, wherein the second peer discovery signal is generated based on the selected peer discovery channel; and transmitting a second feedback signal within the response slot of the second peer discovery period, wherein the peer discovery slot is configured with the transmission slot, the response slot, and a processing time, wherein the transmission slot is configured with the plurality of peer discovery channels for transmitting/receiving the plurality of peer discovery signals, wherein the response slot is configured with the plurality of response channels that is one-to-one mapped to the plurality of peer discovery channels, wherein one response channel of the plurality of response channels consists of a single tone, and wherein the selected peer discovery channel is indicated during the processing time between the transmission slot and the response slot.
