Problems solved by technology

However, the solution provided by Hoydis et al., 2013 is only applicable when all antennas in the array are in either transmit mode or receive mode
Therefore, the solution provided by Hoydis et al. in 2013 is only suitable for half-duplex scenarios

Abstract

This application relates to a method for managing base stations (BS 0 ) and a device (301) for full-duplex communication between a group of user equipments (101a, b), the base station (BS 0 ) includes a plurality of transmitting antennas, and the plurality of transmitting antennas are connected to the base station (BS 0 ) and the downlink communication channel H between the group of user equipments (101a, b) and the base station (BS 0 ) and multiple neighboring base stations (BS i ) between multiple interfering channels of G i Associated, the device (301) includes: a determiner (303), configured to, based on the multiple interference channels G i To determine the aggregated interference channel G, a modifier (305), configured to modify the aggregated interference channel under the constraint that the performance measurement depending on the downlink communication channel H and the modified aggregated interference channel F satisfies a performance measurement criterion channel G to obtain a modified aggregated interference channel F; and a precoder (307) configured to precode signals to be transmitted by the plurality of transmit antennas based on a precoding matrix W.

Description

technical field [0001] This application relates generally to the field of telecommunications. More specifically, the present application relates to devices and methods for managing full-duplex communications between a base station and a plurality of user equipments. Background technique [0002] In-band full-duplex (also known as full-duplex ( FD)) is a promising candidate technology for next generation wireless communication systems. Commonly used half-duplex (half-duplex, HD) systems, such as time division duplex (time division duplex, TDD) or frequency division duplex (frequency division duplex, FDD) systems, respectively use orthogonal time resources or orthogonal frequency resources . A full-duplex base station (BS) can improve spectral efficiency because it uses the same time and frequency resources for both uplink and downlink. figure 1 shows a base station consisting of two full-duplex BS 0 and BS 1 An exemplary communication system 100, BS 0 and BS 1 The sam...
