Abstract: A method for controlling a beam in a cell, includes obtaining traffic distribution data of a plurality of beam areas included in the cell, obtaining a total number of a plurality of beams for a beam area among the plurality of the beam areas, based on the obtained traffic distribution data, and obtaining a beam width of one among the plurality of beams for the beam area, based on the obtained total number of the plurality of beams. The method further includes obtaining, from a candidate beam set, candidate beams for the beam area, based on the obtained total number of the plurality of beams and the obtained beam width of the one among the plurality of beams, and obtaining, from the obtained candidate beams, multiple beams for the beam area, based on a distance between the obtained candidate beams and the beam area.

Abstract: Embodiments of the present disclosure provide reference signal transmitting and receiving methods and devices in an active antenna system. Port virtualization to a transmit antennas may be implemented for multiple cell-specific reference signal (CRS) antenna ports and applying different vertical beamforming vectors to implement port virtualization for the different CRS antenna ports. The User Equipment (UE) reports the maximum RSRP/RSRQ value measured based on multiple CRS ports, or the UE simultaneously reports multiple RSRP/RSRQ values and the information of the multiple CRS antenna ports. Therefore, the coverage problem of the CRS signal and Physical Broadcast Channel (PBCH)/Physical Downlink Control Channel (PDCCH)/Physical Downlink Shared Channel (PDSCH) demodulated based on CRS and the problem of measurement for Radio Resource Management (RRM) in the active antenna system may be avoided. Specifically, the following problems may be solved. 1) Coverage differences between CRS and PBCH/PDCCH/PDSCH demodulated based on CRS transmission and Enhanced PDCCH (E-PDCCH)/PDSCH signal transmission, which is measured based on the CSI-RS or demodulated based on the DMRS may be reduced or avoided. 2) The cell association problem due to the different vertical beamforming technologies adopted by the CSI-RS or DMRS and by the CRS may be avoided. 3) Deep spatial fading state may be avoided for CRS reception and PBCH/PDCCH/PDSCH demodulated based on the CRS.
