Abstract
Methods and apparatus are provided for mitigating cross-link interference. The method is implemented by a base station of a wireless communication system, the base station serving user terminals in a first cell. The method comprises selecting (610) a primary time division duplex, TDD, configuration designating uplink and downlink subframes for communication with the user terminals in the first cell, and determining (620) uplink subframes of the primary TDD configuration that are overlapping in time with downlink subframes of a TDD configuration used in a second cell. The method also comprises transmitting (630), to a user terminal in the first cell, a request to use a supplemental TDD configuration for transmitting uplink control information, wherein uplink subframes of the supplemental TDD configuration are not overlapping in time with downlink subframes of the TDD configuration used in the second cell.
