HIGH SPEED MOVING TERMINAL AND METHOD FOR COMMUNICATING THEREOF IN MOBILE WIRELESS BACKHAUL NETWORK

摘要

A high speed mobile terminal comprises a plurality of pieces of terminal equipment (TE) connected to a plurality of antennas installed on the outside of a high speed mobile object in a mobile wireless backhaul network to independently communicate with a base station. The high speed mobile terminal sets each TE as secondary TE, sets TE ahead of the secondary TE on the basis of the moving direction of the high speed mobile object as primary TE of each TE set as the secondary TE, and calculates a delay time of each TE set as the secondary TE with respect to the corresponding primary TE. In addition, if similarity between a channel estimation value measured by the TE set as the primary TE and a channel estimation value measured by the TE set as the secondary TE after the delay time is satisfied with a set range, the TE set as the secondary TE transmits information on the delay time with the corresponding primary TE to the base station without feedback of information on a channel state.
