RADIO BASE STATION DEVICE, RADIO TERMINAL DEVICE, AND RADIO TRANSMISSION METHOD

WIPO Patent Application WO/2012/085958

A1

[Problem] To provide a radio base station able to have terminals receive control information reliably, without occupying resource blocks wastefully. [Solution] The base station is characterized by the following actions: with respect to a plurality of terminals, setting, on the basis of communication quality information from each radio terminal, the number of resource blocks to which first control information is allocated, said first control information including resource block position information of second control information and second control information being control information of each individual terminal; adjusting first control information to a size based on the number of resource blocks that was set; allocating the adjusted first control information to the number of resource blocks that were set and transmitting same; setting, on the basis of the number of resource blocks to which the first control information was allocated, the number of resource blocks to which second control information is allocated; and allocating second control information to the number of resource blocks based on the number of resource blocks to which second control information that was set is allocated.
