WEIGHTED AGGREGATION-BASED METHOD AND DEVICE FOR TRANSMITTING CONTROL SIGNALS

摘要

The present invention is directed to providing a weighted aggregation based method and device for transmitting control signals. Specifically, the method comprises: determining an aggregation level weighting vector corresponding to a control signal to be transmitted by a plurality of antenna elements corresponding to a port of a common control channel; And transmitting control signals through the plurality of antenna elements according to an aggregation level weighting vector. In comparison with the prior art, according to an embodiment of the present invention, an aggregation level weighting vector corresponding to a control signal to be transmitted by a plurality of antenna elements corresponding to a port of a common control channel is determined, The coverage of the common control channel in the 3D-MIMO system is improved, the problem of coverage holes in the 3D MIMO system due to the introduction of the 2D plane array is solved by transmitting through multiple antenna elements according to the vector, The gain is more uniformly distributed over the entire EOD span, and the gain becomes important.
