Beam-dependent system information
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first synchronization signal associated with a first beam, and receive, from the base station and based at least in part on the first synchronization signal, scheduling information. Accordingly, the UE may receive, from the base station and based at least in part on the scheduling information, first system information associated with the first beam. The first system information may be distinct from second system information associated with a second beam. Additionally, or alternatively, the UE may receive the first system information using one or more first reception parameters that are distinct from one or more second reception parameters for the second system information associated with the second beam. Numerous other aspects are provided.
