In one example, a method includes receiving time period information and destination information for a time period from one or more base station entities (BSEs), each BSE configured to implement some functions for layer(s) of a wireless interface used to communicate with UEs. The method further includes determining a configuration of Ethernet switch(es) based on the destination information for the time period and topology information for the Ethernet switch(es). The Ethernet switch(es) are communicatively coupled to the BSE(s) and configured to: receive downlink fronthaul data from the BSE(s), be communicatively coupled to one or more RUs, and forward downlink fronthaul data from the one or more base station entities to the one or more RUs.

摘要： 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.
