  • Publication number: 20230217425
    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.

  • Publication number: 20230216641
    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.

  • Publication number: 20230216642
    Abstract: A method to jointly perform beam management, synchronization, and L1 measurements using a single synchronization signal block (SSB) burst in NR systems is proposed to improve data rate and to reduce power consumption. In a scheduling based SSB method, a UE is scheduled to perform either beam management or synchronization and L1 measurements alternatively. In a joint SSB method, a UE performs beam management, synchronization, and L1 RSRP/SNR measurements within a single SSB burst simultaneously. The UE can dynamically switch between the two SSB methods based on predefined conditions. Further, multiple joint SSB modes are introduced for the joint SSB method, where either 3 OFDM symbols or 4 OFDM symbols of each SSB burst are used. UE can dynamically switch among the joint SSB modes depending on contamination level on the OFDM symbol carrying PSS.

  • Publication number: 20230216596
    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.
