PDCCH RESOURCE UTILIZATION

摘要

The present disclosure provides coordination of assignments for the physical downlink control channel (PDCCH) in a multi-sector cell based on reuse of CCE resources to user equipment (UE) in different sectors that are well isolated from each other. For non-isolated UEs the CCE resources are either repeated in all sectors for better reception performance, or transmitted in one sector whilst the corresponding CCEs in the other sectors are reserved. In order to achieve coordinated PDCCH assignment there is provided methods for coordinated PDCCH transmission, a system comprising transmission points which are associated with a common physical cell identity and which are controlled by a common network node. There is also provided a corresponding network node and computer readable media comprising computer program code.
