    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.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a configuration specifying an initial aggregated bandwidth W0 carried on C0 component carriers on which a reception unit (RXU) of the UE is to receive signals. The UE determines a total bandwidth WTOT on which the UE is capable of receiving signals. The UE determines, based on WTOT and W0, an initial hardware limit of Q0′ RXUs that the UE is allowed to activate concurrently. The UE determines an adjusted aggregated bandwidth W1 carried on C1 component carriers on which an RXU of the UE is to receive signals based on a channel condition between the UE and the base station.

    Abstract: A method to perform. beam management (BM) and/or synchronization (Sync) using primary synchronization signal (PSS) when pilot contamination is low to improve system performance is proposed. A UE first determines pilot contamination. level on PSS of a synchronization signal block (SSB), depending on different network deployment. scenarios. The UE then adaptively perform BM or Sync, by dynamically adjusting to the pilot contamination level on PSS. If the pilot contamination level is high, then the UE follows a 3-symbol mode, e.g., uses only PBCH0, SSS, and PBCH2 symbols for performing BM or Sync. Otherwise, if the pilot contamination level is low, then the UE follows a 4-symbol mode, e.g., uses PSS as an extra symbol for BM or Sync to improve system performance.
