摘要： The present application relates generally to use of radio resources in a radio access network (RAN) and, in more specific, Full-Duplex (FD) transmission on the same carrier. Due to the mobility of the UEs or the non-optimal grouping, two UEs belonging to different groups may be close to each other while performing transmission and cause serious transmission interferences to 5 each other. This is one of the problems which a method in accordance with the invention aims to solve. When the performing the method a RAN triggers a UE to measure 601 first interferences originated from a first group of UEs. Then the RAN triggers the same UE to measure 602 second interferences originated from a second group of the UEs. Finally, the RAN places 603 the UE into the first group, if the first interferences are higher than the second interferences. The both 10 groups of the UEs are composed of such user equipments which share a group-specific transmission pattern. Uplink and downlink resources of the RAN are scheduled according to a time-division to the UEs, so that simultaneous transmissions are allowed only for such user equipments that belong to different groups. Advantages of the invention are the following: 1) simultaneous transmission and reception is supported in a RAN and in a UE which is either a FD 15 UE or a HD UE, 2) different kinds of interferences are efficiently reduced, and 3) the interferences are measured in a way that saves power.
