Abstract

The invention relates to a method (S100) and wireless communication network node for co-scheduling first and second user equipment (UE). The co-scheduling comprises scheduling the first UE and the second UE in the same time and frequency resource. The method comprises determining if a co-scheduling condition is fulfilled, wherein the co-scheduling condition implies comparing link loss information to a co-scheduling threshold value, and selecting the first and second UE for co-scheduling when the co-scheduling condition is fulfilled.

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...
