Title: METHODS, CENTRAL UNITS, AND DISTRIBUTED UNITS FOR REFERENCE SIGNAL CONFIGURATION
Abstract:
A method for RS configuration is provided. The method includes determining, by a Central Unit (CU), whether to turn on/off a Distributed Unit (DU) within coverage of the CU, wherein the CU connects to and controls a plurality of such DUs, the CU carries upper layers of an air interface protocol stack, and the DUs carry the lower layers; and transmitting, by the CU, a Reference Signal (RS) configuration message to the DU, so that the DU switches from stopping transmitting RS to transmitting a corresponding RS or stops transmitting RS in response to the RS configuration message. Associated CUs and DUs are also disclosed.
