Abstract:
A method of channel hopping in a radio communications system (PLMN), wherein the system (PLMN) includes at least one first radio station (BS1) and one second radio station (MS1) between which radio connections can be established through the medium of radio channels (K1-K4), comprising:measuring a channel quality parameter (I, BER, C/I) for separate radio channels;allocating weight values (W) to individual channels in accordance with the measured channel quality parameters (I, BER, C/I), wherein the weight values are derived by converting the measured channel quality parameters using a conversion function;generating a hopsequence in accordance with the allocated weight values (W) such that each of said radio channels will be repeated in said hopsequence a number of times which is determined by the weight value of each radio channel relative to the weight values of others of said radio channels; andchannel hopping between the channels using the generated hopsequence for communication between the first radio station (BS1) and the said at least one second radio station (MS1).
