WIRELESS COMMUNICATION SYSTEM

摘要

A plurality of MTC devices can connect to a base station device efficiently. The base station device allocates first radio resource for allowing transmission of data to, among MTC devices in a predetermined group that transmit data to the base station device using a common application data format, communication devices having a path loss less than a threshold for notification information transmitted from the base station device. The base station device allocates second radio resource for allowing transmission of data to communication devices having the path loss equal to or greater than the threshold. The communication devices having the path loss less than the threshold transmit the data to the base station device using the first radio resource. Each of the communication devices having the path loss equal to or greater than the threshold transmit the data to the base station device using the second radio resource.
