The embodiment of the invention discloses a pilot signal transmission control method, system and related equipment, which are used to solve the problem of excessive pilot overhead on the basis of realizing dedicated pilot. The method in the embodiment of the present invention includes: the base station obtains the channel demodulation information of the terminal; the base station determines the control information used to transmit the dedicated pilot signal in each scheduling period TTI according to the channel demodulation information and the level of the terminal , wherein, the dedicated pilot signal is used to realize the differentiated value-added service of the terminal, and the control information includes the type of the dedicated pilot signal, the transmission frequency of the dedicated pilot signal and the length of the dedicated pilot signal; the base station sending the control information to the terminal, so that the terminal completes the transmission of the dedicated pilot signal in each TTI according to the control information.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a pilot signal transmission control method, system and related equipment. Background technique [0002] The pilot signal is an important signal in mobile communication, and it is an unmodulated direct sequence spread spectrum signal continuously transmitted by the base station. In the downlink direction, the pilot signal is mainly used for cell search, downlink channel quality measurement and channel estimation, and helps a terminal (User Equipment, UE for short) to obtain channel demodulation information. In the uplink direction, the pilot signal is mainly used for uplink channel quality measurement, power control, timing, and channel estimation to help the base station obtain channel demodulation information. Wherein, it is very important to measure two parameters of the pilot signal during the communication process, and these two parameters include timing advan...
