METHOD FOR PILOT SIGNAL TRANSMISSION METHOD IN MOBILE WIRELESS BACKHAUL NETWORK

摘要

A pilot signal transmission method of a base station on a mobile wireless backhaul network comprises the steps of: a base station being operated as a serving base station, a target base station or an inactive base station of a terminal according to position information of the terminal and the base station; if the base station is operated as the serving base station or the target base station, the base station determining a pilot signal transmission frequency of each of multiple beams operated thereby according to the position information of the terminal; and the base station allocating a wireless resource to the pilot signal of each of the beams to transmit the pilot signal according to a corresponding pilot signal transmission frequency. The present invention reduces unnecessary signal transmission of the base station on the mobile wireless backhaul network which supports high speed moving bodies to reduce power abuse of the base station.
