Abstract: A method of cross component carrier (Cross-CC) beam management is proposed. A transceiver uses multiple CCs' channel measurements to obtain a beam vector such that better performance can be achieved by utilizing wideband channel. The transceiver derives the beam vector by using the channel measurements of a set of selected CCs applied with a carrier weight factor. The transceiver utilizes beam management reference signal (BM-RS) of the set of selected CCs to derive the beam vector, e.g., an optimal beam. In one embodiment, the carrier weight factor can be the number of BM-RS REs of each CC. In another embodiment, the channel measurements can be SNR/RSRP, and the carrier weight factor can be the SNR/RSRP of each CC.
