Methods and apparatus related to power control and/or interference management in a mixed wireless communications system supporting WAN signaling and peer to peer signaling
Methods and apparatus related to the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. The base station regulates the level of interference from the peer to peer signaling by generating and transmitting peer to peer transmission power control signals intended for peer to peer wireless terminals in the local vicinity. A base station transmits into a downlink frequency band a signal, e.g., a beacon or broadcast channel signal, to be used by a peer to peer wireless terminal in controlling its peer to peer transmit power level into the corresponding uplink frequency band. The peer to peer wireless terminal receives and evaluates the base station signal. The determined information from the evaluation is used in determining whether or not peer to peer signal transmission is permitted and/or in determining a peer to peer transmission power level.
