Methods, user equipment and radio network node for interference mitigation in a dynamic time division duplex system
The present disclosure relates to methods, a user equipment and a radio network node for interference mitigation in a dynamic TDD system comprising a user equipment (201, 700), a serving base station (202) serving the user equipment (201, 700), at least one neighboring base station (203) and at least one neighboring user equipment (204) served by the at least neighboring base station (203). The method comprises obtaining (S301) link direction information and at least one transmission parameter, wherein the link direction information and the at least one transmission parameter are associated with downlink transmission of the at least one neighboring base station (203) or uplink transmission of the at least one neighboring user equipment (204). The method further comprises mitigating (S302) interference caused by the downlink transmission or uplink transmission based upon the link direction information and the at least one transmission parameter. The methods, user equipment and radio network node of the present disclosure may overcome or alleviate the interference issues in the dynamic TDD system and give quality and efficiency of the wireless communication a big boost.
