ARRANGEMENT OF BASE STATION, TERMINAL DEVICE, TRANSMITTION METHOD AND RECEIVING METHOD Russian patent published in 2017 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: base station arrangement is disclosed in which the configuration section configures (in the area of the data assigned for the terminal device) the first search space and the second search space, each of which is a possible option, which is assigned with the control information. Each of the first search space and the second search space includes a plurality of control channel members, and signal assignment section assigns control information to each of the first and second search space. In addition, the configuration section allocates numbers for the plurality of the first control channel members included in the first search space, in ascending order, and allocates numbers greater than or identical with the numbers allocated to the first control channel members, for the plurality of the second control channel members included in the second search space.
