1. A communication device, comprising:
a primary sector that includes a baseband signal processor and a first radio head (RH) unit, wherein
a first antenna array of the first RH unit is configured to receive a first beam of first input RF signals associated with a first beam pattern from a base station, or transmit the first beam of the first input RF signals associated with the first beam pattern to the base station,
a controller of the baseband signal processor is configured to:
select a first portion of subcarriers in the first beam of the first input RF signals associated with the first beam pattern that is decoded;
relay the remaining portion of subcarriers in the first beam of the first input RF signals associated with the first beam pattern towards a plurality of user equipment (UEs) without demodulation while maintaining a final error vector magnitude (EVM) target at the plurality of UEs based on the selection of the first portion of subcarriers in the first beam of the first input RF signals associated with the first beam pattern that is decoded;
extract control information based on the first portion of subcarriers in the first beam of the first input RF signals associated with the first beam pattern that is processed and the remaining portion of subcarriers in the first beam of the first input RF signals associated with the first beam pattern;
assign a different timeslot from a plurality of available timeslots to each of the plurality of UE based on scheduling information in a received first beam of the first input RF signals;
detect a location of each of the plurality of UE's based on each of a received signal strength indicator (RSSI) associated with each UE of the plurality of UE's; and
generate beamforming coefficients to convert the first beam pattern of the first beam of the first input RF signals to a second beam pattern based on the control information, a first operating mode of a plurality of operating modes, the assigned different timeslot, and the detected location, wherein the first operating mode is a switching multi-beam mode, and wherein the switching multi-beam mode comprises dynamically switching between the first beam and the second beam for communication with the plurality of UE's, wherein the second beam is wider than the first beam; and
at least one secondary sector that is communicatively coupled to the primary sector and includes a second RH unit, wherein
a second antenna array of the second RH unit is configured to receive a second beam of output RF signals in the second beam pattern from the plurality of UEs or transmit the second beam of the output RF signals in the second beam pattern to the plurality of UEs.
