Summary:In one embodiment, a system comprises a distributed unit (DU) and a plurality of remote units (RUs). All of the RUs are used to serve the same cell. The system can be configured to wirelessly transmit at least some user data to a first user device using a first subset of the RUs and a first beam, where the first subset of the RUs includes less than all of the RUs otherwise used to serve the same cell. In such an embodiment, the system can be configured to determine which RUs are included in the first subset of RUs used to transmit said at least some user data to the first user device based on measurement reports made by the first user device of reference signal transmissions transmitted using multiple beams, where at least some of the reference signal transmissions are transmitted from less than all of the RUs.
