BASE STATION, COMMUNICATION TERMINAL AND COMMUNICATION SYSTEM

摘要

Disclosed is a base station (10B) provided with: a wireless transmission unit (11) which carries out wireless communication with a communication terminal (30A); a wireless resource allocation unit (131) which allocates inidvidual channels in wireless transmission resources; a transmission/reception timing determining unit (132) that determines the transmission/reception timing fortransmission/reception carried out using individual inidvidual channels; a transmission status specifying unit (134) which specifies whether the transmission with the transmission terminal (30A) is indirect transmission carried out via a relay device (50) or direct transmission that does pass through a relay device (50); and a reception timing adjustment unit (133) which adjusts the timing with which individual channels for uplink transmissions are used, in response to the specification results of the communication status specification unit (134).
