Document Type and Number:
Japanese Patent JP5405609
Kind Code:
B2
Abstract:
Methods and apparatus related to the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. Typically, a base station uses its WAN uplink band to receive uplink signals from wireless terminals using the base station as a point of network attachment. In accordance with a feature, a base station injects a signal, e.g., a beacon signal, into its WAN uplink bandwidth, e.g., its WAN frequency division duplex (FDD) uplink band. A peer to peer wireless terminal scans the uplink bandwidth, detects the base station signal, evaluates the received base station signal, and controls peer to peer transmission as a function of the evaluation. Control of peer to peer transmission includes adjusting peer to peer transmission power as a function of the evaluated base station signal. The communications band used for peer to peer communications is, in some embodiments, the same uplink band.
