Abstract

The present invention relates to a method for co-scheduling the first and second user devices UE (S100) and wireless communication network nodes. Co-scheduling involves scheduling the first UE and second UE on the same time and frequency resources. The method comprising: determining whether the co-dispatch condition is satisfied, wherein the co-dispatch condition means that the link loss information is compared with the co-dispatch threshold; When the co-scheduling condition is met, select the first and second UEs for co-scheduling.

Description

technical field [0001] The technology relates to methods and nodes in wireless communication networks. Background technique [0002] A fundamental principle of wireless communication is that a radio cannot transmit and receive on the same frequency at the same time, i.e. cannot operate in the same frequency / time full-duplex mode. Signals from local transmit antennas are much stronger than transmissions from other nodes that have been attenuated by transmission losses. Therefore, it is generally assumed that a radio station cannot decode a received signal while it is transmitting. [0003] Under the assumption of the current cellular system, in order to realize data transmission and reception with the same frequency and the same time, the required interference cancellation capability must be 130-140dB. 80dB interference cancellation is now possible externally and internally. [0004] To enhance interference cancellation capabilities, some aspects can be considered where di...
