摘要： An active repeater device includes a primary sector and at least a secondary sector communicatively coupled to the primary sector receives or transmits a first beam of input RF signals having a first beam pattern from or to a base station, respectively. The primary sector includes an baseband signal processor and a first radio head (RH) unit. The secondary sector comprises a second RH unit. The first beam pattern covers a first geographical area. Beamforming coefficients are generated to convert the first beam pattern of the first beam of input RF signals to a second beam pattern. A second beam of output RF signals in the second beam pattern is transmitted from or received by, respectively, the secondary sector to or from, respectively, a plurality of user equipment (UEs) based on the generated beamforming coefficients and the received first beam of input RF signals.
