METHOD, BASE STATION, AND USER EQUIPMENT FOR TRANSMITTING PILOT SIGNAL

Document Type and Number:

WIPO Patent Application WO/2017/193790

Kind Code:

A1

Abstract:

The application provides a method, base station, and user equipment for transmitting pilot signals, reducing a quantity of pilot symbols in a TTI by configuring a dedicated demodulation pilot signal and a common demodulation pilot signal onto different resource blocks of a TTI, and facilitating pilot extension in a communication system. In one embodiment of the invention, the method comprises: a base station determines resource locations in a TTI and configured to transmit pilot signals, wherein the pilot signals comprise a common demodulation pilot signal and a dedicated demodulation pilot signal, and the dedicated demodulation pilot signal and the common demodulation pilot signal are located on difference resource blocks in the TTI; and the base station transmits the pilot signals on the resource locations used to transmit the pilot signals.
