摘要： The present disclosure relates to an electronic device in a radio communications system and a radio communications method. The radio communications system comprises multiple cells, and the multiple cells comprise a current cell in which an electronic device is located and a neighboring cell. The electronic device comprises: one or more processing circuits. The processing circuits are configured to execute the following operations: obtaining allocation information about reference signals of the current cell and the neighboring cell; determining quality of an available reference signal in the current cell based on the allocation information; and allocating the available reference signal to user equipment based on the quality of the available reference signal. By means of the electronic device and the radio communications method according to the present disclosure, the quality of an available reference signal can be monitored by using interaction information between base stations, thereby implementing optimal configuration of reference signals and improving overall performance of a system.
