Abstract: The invention provides a method for antenna selectin of a user equipment (UE). The UE may comprise a plurality of antennas. The method may comprise calculating one or more quality evaluations respectively associated with one or more first antenna subsets, and selecting one of the one or more first antenna subsets according to the one or more quality evaluations. Each antenna subset may include one or more of the plurality of antennas. Each quality evaluation may be calculated under a condition that the antenna(s) included in the associated antenna subset is (are) used to communicate.

Abstract: A method to perform beam management (BM) and/or synchronization (Sync) with interference cancellation on synchronization signal block (SSB) is proposed. A UE determines interference level and/or pilot contamination level. The UE can then perform BM or Sync, with or without interference cancellation, adapt to the determined interference and pilot contamination level. If interference level is high, UE applies interference cancellation for BM and Sync. If interference level is low, UE does not apply interference cancellation for BM and Sync. If the pilot contamination level is high, then UE follows the 3-symbol mode, e.g., uses only PECH0 SSS, and PBCH2 symbols for BM or Sync. If the pilot contamination level is low, then UE follows the 4-symbol mode, e.g., uses PSS as an extra symbol for BM or Sync to improve system performance.
