A method of operating a wireless communications device supporting peer to peer communications in a base station uplink frequency band, the method comprising: receiving at said wireless communications device (104; 704; 804) a first signal from a base station in a downlink frequency band; performing (106; 706; 806, 808) an evaluation on the first received signal to obtain information through both measuring a signal power level the first received signal and extracting an encoded information conveyed in the first received signal, characterized in that the encoded information or a transmission power level of the first signal is varied by the base station to dynamically regulate interference to the base station uplink frequency band generated by a plurality of peer to peer wireless terminals; and characterized in that the method further comprises: controlling (108; 708; 820) a peer to peer transmission power for at least some peer to peer signal transmission of said wireless communications device in said uplink frequency band as a function of a result of the evaluation of said first received signal, wherein controlling (108; 708; 820) said peer to peer transmission power includes using a first function that limits said peer to peer transmission power to a lower level for the evatluation result of a first the evaluation result of signal power level than for a second signal power level which is higher than said first signal power level. receiving at said wireless communications device (104; 704; 804) a first signal from a base station in a downlink frequency band; performing (106; 706; 806, 808) an evaluation on the first received signal to obtain information through both measuring a signal power level the first received signal and extracting an encoded information conveyed in the first received signal, characterized in that the encoded information or a transmission power level of the first signal is varied by the base station to dynamically regulate interference to the base station uplink frequency band generated by a plurality of peer to peer wireless terminals; and characterized in that the method further comprises: controlling (108; 708; 820) a peer to peer transmission power for at least some peer to peer signal transmission of said wireless communications device in said uplink frequency band as a function of a result of the evaluation of said first received signal, wherein controlling (108; 708; 820) said peer to peer transmission power includes using a first function that limits said peer to peer transmission power to a lower level for the evatluation result of a first the evaluation result of signal power level than for a second signal power level which is higher than said first signal power level. controlling (108; 708; 820) a peer to peer transmission power for at least some peer to peer signal transmission of said wireless communications device in said uplink frequency band as a function of a result of the evaluation of said first received signal, wherein controlling (108; 708; 820) said peer to peer transmission power includes using a first function that limits said peer to peer transmission power to a lower level for the evatluation result of a first the evaluation result of signal power level than for a second signal power level which is higher than said first signal power level.
