Physical downlink control channel configuration for extended bandwidth systems
TLDR
In this article, a resource allocation for a particular system bandwidth is proposed, where the resource allocation has a larger number of resource blocks than a maximum number of resources blocks associated with the specific system bandwidth.Abstract:
The method includes forming a resource allocation for a particular system bandwidth, where the resource allocation has a larger number of resource blocks than a maximum number of resource blocks associated with the particular system bandwidth. The step of forming includes the use of an extended parameter in a derivation of the resource allocation. The method further includes transmitting information descriptive of the resource allocation to user equipment. The resource allocation may be a downlink resource allocation or an uplink resource allocation. The user equipment is enabled to employ a plurality of extended control channel elements as at least one of an extended physical downlink control channel and a physical hybrid automatic repeat request indicator channel. Modification of the PDCCH structure for LTE advanced in order to enable backward compatibility with Release 8 LTE and a greater choice of bandwidth. Carrier Aggregation concept.read more
