Abstract:
A split radio access network is provided that efficiently transmits beamforming coefficients from a distributed baseband unit device to a remote radio unit device to facilitate beamforming at the remote radio unit. The beamforming coefficients can be determined at the baseband unit device and transmitted along with the data to be beamformed to the remote radio unit device. Due to the large number of antenna ports however, there can still be a very large number of coefficients to transmit, and the disclosure provides for a compressed set of coefficients that reduces the overhead signaling requirements. Instead of sending coefficients for every k th  antenna port, the system can select a subset of the coefficients corresponding to a set of k antenna ports which can be used by the remote radio unit to approximate the full set of beamforming coefficients.

Claim (Index 19):
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of an baseband unit device, facilitate performance of operations, comprising:\n determining beamforming coefficients in a split radio access network that facilitates beamforming of a transmission to a user equipment device, wherein the beamforming is performed by a remote radio unit device of the split radio access network; selecting a portion of the beamforming coefficients by selecting a pair of beamforming coefficients from the beamforming coefficients, wherein the pair of beamforming coefficients correspond to an antenna port of a group of antenna ports; and transmitting the portion of the beamforming coefficients to the remote radio unit device via a transmission.
