Embodiment 1

[0074] The application scenario of this embodiment is that in a time division duplex (TDD) system, the uplink-downlink configuration is set to 1 according to the configuration information shown in Table 1, and the special subframe configuration is set according to the configuration information shown in Table 2 If it is 1, the downlink subframe adopts the conventional cyclic prefix, the uplink subframe adopts the conventional cyclic prefix, and the guard interval (GP) may include 4 OFDM symbols.

[0075] In this application scenario, the guard interval GP can be used to send the measurement reference signal, the uplink pilot time slot UpPTS can be used to send the measurement reference signal, or a new special uplink time slot UpPTS2 can be added in the special subframe, using the above The newly added uplink time slot UpPTS2 sends the measurement reference signal.

[0076] like Figure 5 As shown, when using the guard interval GP to transmit the measurement reference signal, ...

Embodiment 2

[0080] The application scenario of this embodiment is that in a time division duplex (TDD) system, the uplink-downlink configuration is set to 3 according to the configuration information shown in Table 1, and the special subframe configuration is set according to the configuration information shown in Table 2. is 0, the downlink subframe adopts the conventional cyclic prefix, the uplink subframe adopts the conventional cyclic prefix, and the guard interval (GP) can include 10 OFDM symbols. In this scenario, there is only one guard interval in the radio frame.

[0081] In this application scenario, the guard interval GP can be used to send the measurement reference signal, the uplink pilot time slot UpPTS can be used to send the measurement reference signal, or a new special uplink time slot UpPTS2 can be added in the special subframe, using the above The newly added uplink time slot UpPTS2 sends the measurement reference signal.

[0082] like Figure 8 As shown, when using t...

Embodiment 3

[0086] The application scenario of this embodiment is that in a time division duplex (TDD) system, the uplink-downlink configuration is set to 6 according to the configuration information shown in Table 1, and the special subframe configuration is set according to the configuration information shown in Table 2. is 5, the downlink subframe adopts the conventional cyclic prefix, the uplink subframe adopts the conventional cyclic prefix, and the guard interval (GP) may include 9 OFDM symbols.

[0087] In this application scenario, the guard interval GP can be used to send the measurement reference signal, the uplink pilot time slot UpPTS can be used to send the measurement reference signal, or a new special uplink time slot UpPTS2 can be added in the special subframe, using the above The newly added uplink time slot UpPTS2 sends the measurement reference signal.

[0088] like Figure 11 As shown, when using the guard interval GP to send the measurement reference signal, the last...

Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a method for sending a radio frame and a measurement reference signal (Sounding Reference Signal, SRS for short) of a mobile communication system. Background technique [0002] A radio frame (radioframe) in a Long Term Evolution (LTE, Long Term Evolution) system includes frame structures in a frequency division duplex (FDD, Frequency Division Duplex) mode and a time division duplex (TDD, Time Division Duplex) mode. The frame structure of FDD mode, such as figure 1 As shown, a 10-millisecond (ms) radio frame consists of twenty time slots (slots) with a length of 0.5ms and numbers 0 to 19, and time slots 2i and 2i+1 form a subframe (subframe) with a length of 1ms. i. The frame structure of TDD mode, such as figure 2 As shown, a 10ms radio frame consists of two halfframes with a length of 5ms, a halfframe includes five subframes with a length of 1ms, an...
