Abstract:
The present invention introduces a method and a system for base station cross-channel measurement control and configuration. A centralized unit (CU) (301, 601) of a base station configures (304, 305) at least two distributed units (DU) (302, 303, 602, 604) with DU sounding signaling transmission objects and DU cross-link measurement objects. The first DU (302) transmits (306) a sounding signal through an air interface (308) which the second DU (303) measures (307). The second DU (303) reports (309) this to the CU (301). Then the second DU (303) transmits (311) a sounding signal through an air interface (312) which the first DU (302) measures (310). The first DU (302) reports (313) this to the CU (301). Beam-forming can be applied as well. Also neighboring operators can be found by inter-frequency measurements of the sounding signals or Synchronization Signals. The CU (301, 601) can control the DUs (302, 303, 602, 604) with appropriate TDD switching patterns based on the found cross-link interference levels.
