Claim Text:
1. A method of discovering neighboring wireless devices, the method comprising: assigning a first discovery channel resource to a transmitting wireless device for a first neighbor discovery round such that the transmitting wireless device is configured to transmit a first neighbor discovery signal based on the first discovery channel resource in the first neighbor discovery round, wherein assigning the first discovery channel resource includes assigning a first discovery channel time slot and a first discovery channel frequency based on a first discovery channel scheduling matrix that includes first time slot and frequency assignments for the transmitting wireless device and a plurality of other wireless devices; assigning a second discovery channel resource to the transmitting wireless device for a second neighbor discovery round such that the transmitting wireless device is configured to transmit a second neighbor discovery signal based on the second discovery channel resource in the second neighbor discovery round, wherein assigning the second discovery channel resource includes assigning a second discovery channel time slot and a second discovery channel frequency based on a second discovery channel scheduling matrix that includes second time slot and frequency assignments for the transmitting wireless device and the plurality of other wireless devices and wherein the second discovery channel scheduling matrix is based on a binary-splitting scheme performed with respect to the first discovery channel scheduling matrix; receiving neighbor discovery signal information associated with one or more of the first neighbor discovery signal and the second neighbor discovery signal as received by a receiving wireless device; and directing the transmitting wireless device and the receiving wireless device to participate in device-to-device communication with each other based on the neighbor discovery signal information.
