Abstract: A high speed moving terminal including first and second antennas each communicating with first and second radio units (RUs) of a base station distributedly installed in a mobile wireless backhaul network communicates with the first and second RUs, respectively, with different uplink-downlink configuration of the first RU and the second RU, and transmits control information of the corresponding downlink signal in an uplink subframe that comes first in the time domain after processing latency of a downlink signal received from the first RU among uplink frames with the uplink-downlink configurations of the first RU and the second RU if the downlink signal is received from the first RU through the first antenna.

Abstract: Disclosed is a method and apparatus for communication in a millimeter band communication system. In a case in which a first terminal obtains a list including members of a cooperative group in which terminals receive a service with the same beam as a first terminal's beam, the first terminal informs a second terminal, corresponding to a member of the list, of communication link failure when the failure occurs, and requests a cooperative service. After that, the first terminal receives information on the service from a base station through the second terminal.
