Embodiment 2

[0253] 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, the downlink subframe adopts a conventional cyclic prefix, and the uplink subframe adopts a conventional cyclic prefix .

[0254] For terminals whose version is Rel-12 or before Rel-12 (denoted as traditional terminals), the base station can set the special subframe configuration according to Table 2, assuming that configuration 6 is used, that is, downlink pilot time slot, guard interval, uplink pilot The number of symbols in the time domain occupied by the time slot is 9, 3, 2.

[0255] For terminals whose versions are Rel-13 or later (referred to as new version terminals), the number of newly added uplink pilot slot symbols (2 or 4) can be configured through RRC signaling. The number of symbols in the slot is equal to the number of symbols in the downlink pilot slot repr...

Abstract

The present invention provides a method and device for sending a measurement reference signal SRS, wherein the method includes: a user equipment sends a measurement reference signal SRS to a base station on a time domain symbol of a special subframe, wherein the time domain symbol includes an uplink guide One or more time-domain symbols in the time-domain symbols occupied by the frequency time slot, the number of time-domain symbols occupied by the uplink pilot time slot is N, where N is an integer, and 3≤N≤12, which solves the problem of time domain The technical scheme for sending SRS on domain symbols is not perfect, and realizes the sending of SRS on increased time domain symbols.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending a measurement reference signal SRS. Background technique [0002] The radio frame (Radio Frame) in the long term evolution (Long Term Evolution, referred to as LTE) system includes a frequency division duplex (Frequency Division Duplex, referred to as FDD) mode and a time division duplex (Time Division Duplex, referred to as TDD) mode frame structure. figure 1 It is a schematic diagram of the frame structure according to the FDD mode in the related art, 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. figure 2 It is a schematic diagram of the frame structure according to the TDD mode in the related art, such as figure 2 As shown, a 10ms radio frame consists of two half frame...
