HIGH SPEED MOVING TERMINAL AND METHOD FOR TRANSMITTING CONTROL INFORMATION THEREOF AND METHOD FOR RECEIVING CONTROL INFORMATION OF BASE STATION IN MOBILE WIRELESS BACKHAUL NETWORK

摘要

The present invention is to provide a method for transmitting control information from a high speed moving terminal including the first and second antenna each communicates with the first and second radio unit (RU) installed separately in a mobile wireless backhaul network for decreasing transmission delay of control information in a mobile wireless backhaul network for a high speed moving terminal. The present invention comprises the steps of: a communication step for communicating with the first and second RU according to a uplink-downlink configuration of the first and second RU; a receiving step for receiving a downlink signal from the first RU through the first antenna; and a transmitting step of transmitting uplink control information from a uplink sub-frame which temporally precedes after delay time of a signal process of the downlink signal received from the first RU from uplink frames according to the uplink-downlink configuration of the first and second RU.
