Wireless communication system devices

摘要

A Down Link control signalling Physical layer enhancement allows for a wireless network to send additional information to a wireless communication device (102) in connected mode in order to reduce the number of Blind Decodes the device has to perform over the physical downlink control channel PDCCH to find its Downlink Control Information DCI within a subframe. An auxillary DCI message is generated by an eNodeB for transmission to a User Equipment. The auxillary DCI message may contain information including the DCI format, the Aggregation Level and the Control Channel Element CCE index number, This information is used by the UE to reduce the search space for the conventional DCI messages and therefore reduce the number of blind decodes needed.
