Title
(EN) Enchanced use of frequency spectrum in wireless communication network
(ZH) 无线通信网络中频谱的增强使用
Abstract
(EN)
The invention relates to a user terminal (1) arranged for communication with at least one node (2) in a wireless communication network (3). The user terminal (1) is arranged to measure received signal characteristics from at least one other user terminal (4, 5) when it is transmitting signals (6, 7; 8, 9). The measured received signal characteristics are comprised in measurement data. The user terminal (1) is arranged to transfer the measurement data to the node (2) at certain times. The present invention also relates to a node (2) that is arranged to schedule transmission and reception of signals such that each user terminal (1, 4, 5) that communicates via the node (2) either transmits or receives signals to/from the node (2) at a first frequency interval. The node (2) is arranged to transmit and receive signals simultaneously at the first frequency interval. The invention also relates to a method.
