Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a wireless communication terminal, the method comprising: scanning an uplink bandwidth to detect a signal from a base station, wherein the signal from the base station is a beacon signal; evaluating the signal from the base station; and transmitting a peer-to-peer signal, responsive to the evaluating the signal from the base station, wherein the peer-to-peer signal is transmitted on the same uplink bandwidth as the detected beacon s…
