Abstract: Various embodiments relate to using available spectrum for peer to peer communications and for selecting which of several possibly available channels should be used. Various methods and apparatus are well suited to peer to peer networks in which channel usage decisions are made in a decentralized manner. A wireless terminal generates a list of potential available channels to be used for peer to peer communications, e.g., based on FCC information and/or local sensing. Channels are filled in accordance with a predetermined channel ordering. A wireless terminal migrates between the channels in accordance with changes in the number of peer devices using a channel. The network, in a distributed manner, changes the number of channels in use at a location in response to changes in numbers of active peer devices at a location.

Abstract: Methods, devices, and computer program products for transmitting and receiving discovery and paging messages are described herein. In one aspect, an apparatus operable in a wireless communication system includes a transmitter and receiver. The transmitter transmits a discovery packet during a first discovery interval of a plurality of discovery intervals. The discovery packet advertises a service provided in a wireless communications network, and the plurality of discovery intervals include recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets. The receiver receives a paging packet from a first device during a first paging interval of a plurality of paging intervals. The paging packet indicates interest in the service, and the plurality of paging intervals include recurring time intervals when the plurality of devices are configured to transmit and receive paging packets. The plurality of paging intervals do not overlap the plurality of discovery intervals.

Abstract: Methods, devices, and computer program products for transmitting and receiving discovery and paging messages are described herein. In one aspect, an apparatus operable in a wireless communication system includes a receiver and transmitter. The receiver receives a registration packet from a first device. The registration packet indicates interest in a service provided by another device in a wireless communications network. The receiver further receives a discovery packet from a second device during a first discovery interval of a plurality of discovery intervals. The discovery packet advertises a service provided by the second device, and the plurality of discovery intervals include recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets in the wireless communications network. The transmitter transmits a notification packet configured to enable the first device and the second device to communicate directly.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with minimizing D2D overhead resource usage. In one example, a first UE is equipped to measure a first received power value from a second UE with which the first UE has a D2D link, and a received power value from each UE of one or more other UEs, determine whether the received power value from any of the one or more other UEs is greater than a relevant interferer threshold, and transmit the received power value for any of the one or more other UEs for which the received power value is determined to be greater than the relevant interferer threshold. In an aspect, the relevant interferer threshold may be based on a fractional value of the first received power value.
