Abstract

Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).
