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.

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.
