Patent ID: 8849216

Claim:
A method of operating a base station, the method comprising: receiving channel feedback information from a communications device; determining an interference adjustment factor according to CQI adj_nonQPSK = 1 Interf_Adj ⁢ CQI feedback ⁢ ⁢ = 1 Interf FFR ⁡ ( RB ) / Interf noFFR ⁢ CQI feedback , where CQI feedback is the channel feedback information, Interf_Adj is the interference adjustment factor, Interf FFR (RB) is wideband interference at the resource block when fractional frequency reuse is used, and Interf noFFR is wideband interference when fractional frequency reuse is not used; adjusting the channel feedback information in accordance with the interference adjustment factor; and adjusting transmission parameters of the base station using the adjusted channel feedback information.
