A radio frame and method are provided for sending a sounding reference signal (SRS) in a mobile communication system, which is used to solve the problem of shortage of resources for sending the SRS in the mobile communication system. The method includes a user equipment (UE) sending the SRS to eNB in time-frequency resources corresponding to a guard space in the radio frame, wherein, the guard space is one or more of downlink to uplink guard space, uplink to downlink guard space, reserved subframes, or reserved idle resources. A device is also provided for sending the SRS, applied to the UE in the mobile communication system, wherein the device includes a radio frame construction module and a sounding reference signal transmission module. |

1. A method for sending a sounding reference signal in a mobile communication system, comprising:
a user equipment UE sending the sounding reference signal to an e-node-B, eNB in time-frequency resources corresponding to a guard space in a radio frame, wherein the guard space is one or more of a downlink-to-uplink guard space, an uplink-to-downlink guard space, reserved subframes, or reserved idle resources; wherein when the sounding reference signal is sent in the time-frequency resources corresponding to the uplink-to-downlink guard space, the sounding reference signal is sent in one or more of first n OFDM symbols of the time-frequency resources corresponding to the guard space, wherein, a destination sounding reference signal is sent in one of the n OFDM symbols, and the value of n is 1, 2, 3, 4, 5 or 6; when the sounding reference signal is sent in the time-frequency resources corresponding to the uplink to downlink guard space, an original uplink timing advance amount is increased by Offset, wherein the Offset is one or more OFDM symbols of n OFDM symbols and a time length corresponding to one or more cyclic prefixes corresponding to the one or more OFDM symbols; and the value of n is 0, 1, 2, 3, 4, 5 or 6; in a time division duplex system, in the step of the UE sending the sounding reference signal to the eNB in the time-frequency resources corresponding to the guard space in the radio frame, the UE sending the sounding reference signal to the eNB in time-frequency resources corresponding to a guard period or an uplink pilot time slot of a special subframe in the radio frame; in a time division duplex system, in the step of the UE sending the sounding reference signal to the eNB in the time-frequency resources corresponding to the guard space in the radio frame, the UE sending the sounding reference signal to the eNB in time-frequency resources corresponding to an uplink time slot between an uplink pilot time slot and a guard period of a special subframe in the radio frame. |
