Abstract

The invention provides a configuration method and a configuration apparatus of a demodulation reference signal, a network side device and a terminal. The configuration method of the demodulation reference signal for the network side device comprises the following steps: generating uplink dispatching signaling, wherein the uplink dispatching signaling comprises demodulation reference signal configuration information; and transmitting the uplink dispatching signaling to the terminal at a downlink subframe sTTI n, wherein the demodulation reference signal configuration information indicates a position of an OFDM symbol occupied by the demodulation reference signal contained in the uplink subframe sTTI (n+1) of the terminal for transmitting uplink data. By virtue of the technical scheme of the invention, the resource overhead of the demodulation reference signal can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a demodulation reference signal configuration method, a demodulation reference signal configuration device, a network side device and a terminal. Background technique [0002] With the development of the mobile Internet, a large number of application services satisfying various specific functions have emerged. Some of these services have lower requirements on data delay, such as sending and receiving emails, downloading movies, etc.; but some other services have strict requirements on data delay, such as online games, snapping up, grabbing red envelopes, etc. The delay of user data is required to be as short as possible. In an LTE (Long Term Evolution, Long Term Evolution) network, a transmission time interval (TTI, Transmission Time Interval) is an important indicator affecting user data delay. The TTI used by the current LTE system is 1ms, that is, one subfram...
