METHOD AND NETWORK NODE FOR PROVIDING RADIO RESOURCES FOR RADIO COMMUNICATION IN A CELLULAR NETWORK

摘要

A method and network node(600)of a cellular network, for providing radio resources in groups of resource blocks in frequency domain in a first system bandwidth (BW1) and in a second system bandwidth (BW2) that overlaps the first system bandwidth, wherein the first and second system bandwidths have a common frequency centre (CF), the radio resources being useful for radio communication with mobile terminals.A first resource block group size S1 is applied for the first system bandwidth and a second resource block group size S2 = N x S1 is applied for the second system bandwidth where N is an integer. Further, radio resources are applied in the first system bandwidth according to the first resource block group size S1and in the second system bandwidth according to the second resource block group size S2. The network node(600)then signals the applied radio resources to mobile terminals (604, 606).
