Abstract
A sever transmits an acknowledgement in response to data transmission from first and second terminals, respectively, among a plurality of terminals. The server controls the first and second terminals so that the first and second terminals open a reception slot at substantially the same timing. The server transmits a collective acknowledgement shared by the first and second terminals during both of the first and second terminals open the reception slot.
