Publication number: 20220109490Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a polarization of at least one synchronization signal block (SSB). The UE may determine a polarization of another beam based at least in part on the indicated polarization. Numerous other aspects are provided.Type: ApplicationFiled: September 8, 2021Publication date: April 7, 2022Inventors: Liangping MA, Xiao Feng WANG, Peter GAAL, Alberto RICO ALVARINO, Ayan SENGUPTA, Lizhi ZHENG, Bharat SHRESTHA, Jun MA, Umesh PHUYAL
