Abstract

The invention discloses a data transmission method in a wireless communication system. The data transmission method comprises the steps that: dynamic configuration signalling used for channel state information CSI reporting is generated and sent; the dynamic configuration signalling is sent through a physical layer or a medium access control MAC layer; the dynamic configuration signalling comprises at least one piece of information as follows: an identifier of the dynamic configuration signalling, a first identifier and a CSI reporting type; and the first identification is used for indicatingradio resource control RRC layer configuration used for CSI reporting. The invention further provides a corresponding data transmission device. By the above manner, compared with dynamic signalling configuration of RRC layer signalling, a relatively flexible and configurable dynamic signalling configuration mechanism is provided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method and device in a wireless communication system. Background technique [0002] With the extensive deployment of Long Term Evolution (English: Long Term Evolution, LTE for short) networks to meet users' needs for wireless data services, the industry has begun to promote the standardization of next-generation wireless communication systems (5G). Among them, multiple user multiple input multiple output (English: Multiple Input Multiple Output, MIMO for short) is a key technology of LTE and future 5G systems. The measurement and reporting of channel state information (English: Channel State Information, CSI for short) plays an extremely important role in LTE and 5G systems using MIMO. [0003] The configurations related to CSI measurement reporting in the current LTE system are all completed through RRC signaling, which is a semi-static configu...
