Abstract

The invention provides a signalling configuration method and apparatus. The method comprises: a base station notifies user equipment of the first special subframe configuration and the second special subframe configuration through a first signalling and a second signalling, wherein the base station and the user equipment determine the first special subframe configuration according to the first signalling, and determine the second special subframe configuration according to the first signalling and the second signalling, or determine the second special subframe configuration according to the second signalling. The signalling configuration method and apparatus solve the problem of low multiplexing capacity of a SRS, and improves the multiplexing capacity of the SRS.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a signaling configuration method and device. Background technique [0002] The radio frame in the Long Term Evolution (referred to as LTE) system includes frequency division duplex (Frequency Division Duplex, referred to as FDD) mode and time division duplex (Time Division Duplex, referred to as TDD) mode frame structure. 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. Subframe i is defined as two time slots with a length of 0.5ms. 2i and 2i+1. [0003] In the above two frame structures,...
