摘要： A method for transmitting an uplink channel sounding pilot is used in the Long Term Evolution Project. The method includes: receiving, by a User Equipment, an uplink channel sounding pilot scheduling signaling; and transmitting, by the User Equipment, an uplink channel sounding pilot according to an indication in the uplink channel sounding pilot scheduling signaling. The uplink channel sounding pilot scheduling signaling includes one of or a combination of indication information including transmission starting time, a transmission period, duration, a subcarrier index, a subframe index, a long block index and a frequency band of the uplink channel sounding pilot. A system for transmitting an uplink channel sounding pilot, a base station and a User Equipment are also disclosed. With the use of the invention, a User Equipment may be dynamically scheduled to transmit an uplink channel sounding pilot, a solution for carrying the uplink channel sounding pilot scheduling signaling is provided, and a solution for determining the position of the uplink channel sounding pilot in the subframe is also be provided, thereby the position of the uplink channel sounding pilot in the subframe can more accurately reflect the conditions of the channel on which uplink and/or downlink processing is performed according to the uplink channel sounding pilot.
