Abstract

Systems and methods for beamforming of broadcast and synchronization channels are provided. In one example, a system includes a BBU, RU(s) communicatively coupled to the BBU, and antennas communicatively coupled to the RU(s). Each RU is communicatively coupled to a respective subset of antennas. The BBU, RU(s), and antennas implement a base station for wirelessly communicating with UEs. The base station is configured to map a synchronization signal to the antennas during a sequence of time periods, transmit the synchronization signal via each respective subset of antennas with a first antenna beam pattern during a first time period of the sequence of time periods, and transmit the synchronization signal via each respective subset of the antennas with a second antenna beam pattern during a second time period of the sequence of time periods. The first antenna beam pattern is different than the second antenna beam pattern.
