COMMUNICATION TERMINAL, MOBILE COMMUNICATION SYSTEM, COMMUNICATION METHOD

摘要

Disclosed is a communication terminal capable of receiving communication information destined to itself from a base station even when the local station has a small battery remaining amount and cannot transmit or receive directly to/from a base station. A mobile communication system including the communication terminal and a communication method are also disclosed. Communication terminals (1, 2) perform radio communication between the local station and other station and requests a base station (3) to transmit communication information obtained according to the reception state of the local station so as to perform transmission power control. When the transmission power is lower than a relay request setting value obtained from the local station battery remaining amount and the transmission power setting, a relay request is made to other station and communication information destined to the local station is received via the other station.
