Improving performance for cellular communication with reduced bandwidth

Abstract

A method comprising receiving an indication of modifying of at least one control channel element structure within an initial control resource set that is configured for an apparatus, determining at least one modified control channel element structure for at least one aggregation level in the initial control resource set, monitoring physical downlink control channel from the initial control resource set according to the modified control channel element structure, and receiving a physical downlink shared channel according to the physical downlink control channel received via the modified control channel element structure.
