INDICATION METHOD AND SYSTEM FOR UPLINK DEMODULATION REFERENCE SIGNALS

摘要

The present invention discloses an indication method and an indication system for uplink demodulation reference signals. The method includes that: a base station transmits indication information to a user equipment; the indication information is used to indicate at least one of the followings: cyclic shifts of the demodulation reference signals, orthogonal masks of the demodulation reference signals, and sequence hopping/sequence group hopping modes of the demodulation reference signals; the user equipment transmits data and the demodulation reference signals to the base station according to the received indication information. The present invention can indicate parameters of the demodulation reference signals to meet requirements of uplink multi-antenna port transmission.
