摘要
Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may use quasi co-located antenna ports for transmission and reception of synchronization and/or reference signals and positioning reference signals. For example, the base station may identify a quasi co-location relationship indicating that antenna ports of the base station used to transmit a synchronization signal are quasi co-located with antenna ports of the base station used to transmit a positioning reference signal. In some cases, the base station may transmit an indication of the quasi co-location relationship to the UE. Additionally, the UE may receive the synchronization signal and determine a receive beam for the UE to use to receive the positioning reference signal based at least in part on the received synchronization signal and the identified quasi co-location relationship. The UE may then receive a positioning reference signal using the determined receive beam.
