Title:
COMMUNICATION SYSTEM, BASE STATION, RADIO DEVICES, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/022736
Kind Code:
A1
Abstract:
The objective of the invention is to suppress the increase of data amount for a communication control and then multiplex, among a plurality of radio devices, transmission unit data that a base station transmits/receives at transmission time intervals between the base station and the radio devices. A base station comprises: a division number notification unit that notifies each of a plurality of radio devices of a division designation value by which to divide, into a plurality of divisional areas, the data area, which corresponds to transmission time intervals, of a shared channel that is time multiplexed in transmission time intervals between the base station and the plurality of radio devices; and a divisional data setting unit that sets data, which are to be addressed to the radio devices being destinations, for the divisional areas into which the data area has been divided on the basis of the division designation value. Each of the plurality of radio devices comprises a local station data acquisition unit that retrieves, from the data area of the received shared channel corresponding to the transmission time intervals, a divisional area including the data addressed to the local radio device.
