Title:
WIRELESS COMMUNICATION SYSTEM, WIRELESS BASE STATION DEVICE, USER TERMINAL AND COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/168561
Kind Code:
A1
Abstract:
In this wireless communication system, signaling of cell index information is realized suitable for CoMP transmission and reception technology. A wireless base station device of a specific cell generates, in a physical downlink control channel shared between multiple jointly transmitting cells, downlink control information which includes the indices of a CoMP set, wherein said downlink control information is generated on the basis of a table comprising a mapping onto bit data of indices indicating the cooperating cells that will be transmission points in CoMP transmission and indices of a CoMP set that indicates combinations of multiple cells which transmit jointly in the CoMP transmission.
