Provided are examples of methods of a vehicular moving relay in a communication system including the vehicular moving relay, a moving terminal, and a macro base station. Also provided is an example of a terminal. The vehicular moving relay may repeatedly transmit data to a vehicular moving terminal without requesting a handover from a macro base station to the vehicular moving relay, using a unique code that is allocated to the vehicular moving terminal from the macro base station.

Communication method of a macro base station, a vehicular moving relay, and a vehicular moving terminal

Provided are a method and system for handing over a mobile terminal between a macro base station and a vehicular base station to secure a communication service of a movable mobile terminal in a wireless communication system supporting a vehicular base station such as a vehicular relay station. The mobile terminal may be handed over by selecting a network or a vehicular base station suitable to a mobility and type of communication.

Method and system for supporting handover between macro base station and vehicular base station

A communication method of a serving micro base station is provided. The method includes a handover of a vehicular mobile terminal based on uplink broadcast information including a unique access code allocated to the vehicular mobile terminal within a multi-cell group. The multi-cell group includes a macro base station and a plurality of micro base stations within a cell coverage of the macro base station. The handover is performed based on a determined preparation level of the handover that is based on the uplink broadcast information.

Communication method of a vehicular mobile terminal, a macro base station, a neighbor micro base station, and a serving micro base station in a multi-cell group

Provided is a communication method of a base station and a target terminal. Resources used for a channel feedback may be reduced by determining a wireless resource based on information about a channel and information about a mobility of the target terminal in each of at least one route, and by feeding back channel state information.
