Abstract

Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving a first set of multiple sets of synchronization signal block (SSB) signals from a network entity. The first set of multiple sets of SSB signals may be associated with a first antenna port of the network entity corresponding to a first polarization. Additionally, the UE may receive a second set of multiple sets of SSB signals from the network entity. The second set of multiple sets of SSB signals may be associated with a second antenna port of the network entity corresponding to a second polarization. The UE may then transmit an indication of a beam pair for communication between the UE and the network entity based at least in part on receiving the first set of multiple sets of SSB signals and the second set of multiple sets of SSB signals.
