Patent ID: 10616877

Abstract:
Methods and devices for configuring an initial active downlink bandwidth part as part of an initial access procedure are provided. In one provided method, a base station broadcasts a synchronization signal block (SSB) that includes a control resource set (CORESET) configuration index. The CORESET configuration index is one of a plurality of CORESET configuration indexes, each CORESET configuration index being associated with a respective configuration of a CORESET. Each configuration includes a CORESET frequency size, a CORESET time duration, and a frequency offset of the CORESET with respect to the SSB selected from a set of predefined frequency offsets. The initial active downlink bandwidth part is defined as having the same frequency location and bandwidth as the CORESET. The base station transmits, as part of a physical downlink control channel (PDCCH) within the CORESET, information indicating scheduling of remaining minimum system information (RMSI) in a physical downlink shared channel (PDSCH).
