Abstract

The invention discloses a reference signal indication method, network equipment and terminal equipment. The method comprises: configuring a target reference signal pattern used in the next transmission time interval for the terminal equipment; when the target reference signal pattern is a default reference signal pattern When the reference signal indication information is not sent to the terminal equipment; or, when the target reference signal pattern is the same as the reference signal pattern indicated by the reference signal indication information received last time, the reference signal indication information is not sent to the terminal equipment; the target reference signal The signal pattern is one selected from a plurality of preset reference signal patterns. When using the default reference signal pattern in the next transmission time interval or using the same reference signal pattern as in the previous transmission time interval, the present invention does not send reference signal indication information, and on the premise of ensuring that the reference signal pattern is accurately indicated, the system is reduced. The number of times information is sent, thereby saving the bit overhead of system information and improving the service transmission rate.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a reference signal indication method, network equipment and terminal equipment. Background technique

[0002] In the traditional LTE (Long Term Evolution, long-term evolution) system, the reference signal is used for channel estimation and channel measurement of the traffic channel and the control channel. In the future 5G (5Generation, fifth generation) mobile communication system, the reference signal pattern can vary with different Scenarios such as business, value configuration, and DMRS functions need to change dynamically, and need to be indicated through specific control information, but the reference signal pattern may undergo frequent dynamic changes, which will bring serious signaling indication overhead and reduce the service transmission rate. For example, DMRS (De-modulation Reference Signal, demodulation reference signal) is mainly used for demodulati...
