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 is 1, the downlink subframe adopts a normal cyclic prefix, the uplink subframe adopts a normal cyclic prefix, and the guard interval (GP) can 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 also 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 measurement reference signals.

[0076] Such as Figure 5 As shown, when the guard interval GP is used to send the measurement reference signal, the last OFDM symbo...

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 If it is 0, the downlink subframe uses a regular cyclic prefix, and the uplink subframe uses a regular cyclic prefix. The guard interval (GP) can contain 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 also 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 measurement reference signals.

[0082] Such as Figure 8 As shown, when the guard inter...

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 normal cyclic prefix, the uplink subframe adopts the normal cyclic prefix, and the guard interval (GP) can 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 also 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 measurement reference signals.

[0088] Such as Figure 11 As shown, when the guard interval GP is used to send the measurement reference signal, the last OFDM ...

Abstract

The invention discloses a wireless frame of a mobile communication system and a sending method of a measurement reference signal. A terminal transmits a measurement reference signal to a base station on a time frequency source corresponding to a protective zone in the wireless frame, wherein, the protective zone is one or more of a descending to an ascending protective zone, an ascending to a descending protective zone, a pre-reserved subframe or a pre-reserved idle resource. In a time division duplex system, the protective zone is a frequency division resource corresponding to the protective interval of a specific subframe or an ascending pilot frequency time slot or is an ascending time slot newly added in the specific subframe, and the terminal transmits the measurement reference signal on a time frequency source corresponding to the protective interval of the specific subframe or the ascending pilot frequency time slot or the ascending time slot. In a frequency division duplex system, the protective zone is a pre-reserved subframe or a symbol resource pre-reserved in the subframe. In the invention, the time frequency source for transmitting reference signals is added to meet the transmission requirements for measuring the reference signal of more users.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for sending a wireless frame and a measurement reference signal (Sounding Reference Signal, SRS for short) of a mobile communication system. Background technique [0002] A radio frame (radio frame) 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 wireless frame of 10 milliseconds (ms) consists of twenty slots (slots) with a length of 0.5ms and numbers 0 to 19, and 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 half frames with a length of 5ms. A half frame includes five subframes with a length of 1ms. Subfr...
