Title: TRANSMISSION DEVICE, METHOD, AND SYSTEM FOR REFERENCE SIGNAL
Abstract:
The present invention relate to the technical field of radio communication, specifically relates to a transmission device, method, and system for a reference signal, and is for use in reducing transmission resources occupied by the reference signal. In the reference signal transmission device provided in embodiments of the present invention, a processing unit generates a reference signal, a transmitter unit transmits the reference signal to the external, where in one subframe on a time domain, the reference signal occupies at least three symbols, while on a frequency domain, in each physical resource block (PRB) occupied by the reference signal, the reference signal occupies multiple discontinuous subcarriers, and on the time domain, the length of one symbol occupied by the reference signal is equal to the length of a data symbol, or, at least three symbols occupied by the reference signal comprise at least one short reference signal of a length less than the length of one data symbol. By either having the reference signal occupying discontinuous subcarriers on the frequency domain, or reducing the symbol length of the reference signal on the time domain, achieved is the goal of reducing the transmission resources occupied by the reference signal.
