Abstract: 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.

Abstract: Techniques for determining if a given remote unit of a centralized radio access network (C-RAN) has physically moved are disclosed. This can be done, for example, by determining signal reception metrics for other remote units in the C-RAN based on at least one transmission associated with the given remote unit and determining if the given remote unit has physically moved as a function of the signal reception metrics for the other remote units.

Abstract: A Citizens Broadband Radio Service (CBRS) communication system is provided. The CBRS communication system includes at least one baseband controller communicatively coupled to a spectrum access system (SAS) that allocates radio frequency (RF) channels in the CBRS communication system. The at least one baseband controller is communicatively coupled to at least one radio point (RP) using a switched ETHERNET network. Each of the at least one RP implements at least one Citizens Broadband Radio Service device (CBSD) that is communicatively coupled to the SAS and configured to provide wireless service to user equipment (UEs) using one or more of the RF channels allocated by the SAS.
