Abstract

The invention provides a method and a system for indicating an uplink demodulation reference signal. The method comprises the following steps: a base station sends indication information to user equipment, wherein the indication information indicates at least one of the cyclic shift, the orthogonal cover code and the sequence hopping / sequence group hopping (SGH) mode of the demodulation reference signal; and the user equipment sends data and the demodulation reference signal to the base station according to the orthogonal cover code of the demodulation reference signal. The invention can indicate the parameters of the demodulation reference signal so as to meet the requirements of uplink multi-antenna port transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for indicating an uplink demodulation reference signal. Background technique [0002] In the Long Term Evolution (LTE for short) system of The 3rd Generation Partnership Project (abbreviated as 3GPP), centralized scheduling of base stations is used to control user equipment (User Equipment, UE for short). ) transmission on a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH for short). [0003] The uplink scheduling information (Uplink Scheduling Information) for the PUSCH is sent by the base station to the target UE through a physical downlink control channel (Physical Downlink Control Channel, PDCCH for short). The uplink scheduling information includes: control information such as resource allocation related to the physical uplink shared channel, modulation and coding schemes, and cyclic shift (Cyclic Shift) of a demodulation referenc...
