Abstract

A controller section (26) generates at least two control signals for designating a burst for transmission of a random-access signal to a terminal device in a single down-subframe. A baseband processing section (24) and the like allocate each of at least two control signals to a burst different one another in the down-subframe for transmission. The baseband processing section (24) and the like receive the random-access signal from the terminal device in the burst designated for each of at least two control signals and in the burst in an up-subframe corresponding one-to-one to the burst with each control signal allocated. In a corresponding combination of the burst with the control signal allocated and the burst with the random-access signal allocated, control of the antenna directivity is shared in common.
