Abstract:
Methods, systems, and devices for wireless communication are described. A base station may use quasi co-located antenna ports for transmission of synchronization signal(s)/reference signal(s) and paging signals. For example, the base station may use a first antenna port configuration for transmission of the synchronization/reference signal(s) and a second antenna port configuration for transmission of the paging signal (e.g., paging indicator, paging message, etc.). The base station may transmit an indication of the quasi co-located antenna ports. A user equipment (UE) may receive the synchronization signal and, based on the antenna ports being quasi co-located, receive the paging signal. In some examples, the UE may determine which receive beam to use to receive the paging signal based on the antenna ports being quasi co-located. In some aspects, the UE may use a reference signal transmitted on antenna ports that are quasi co-located with the paging signal antenna ports.
