[0036] In this embodiment, the method for indicating the reference signal at the network device side of the present invention will be briefly introduced and described in conjunction with the accompanying drawings. Specifically, such as figure 1 As shown, the embodiment of the present invention provides a method for indicating a reference signal, which specifically includes the following steps:

[0037] Step 11: Configure the target reference signal pattern used in the next transmission time interval for the terminal equipment.

[0038] Among them, in the future 5G mobile communication system, in order to meet the scene requirements of different numerical configurations and dynamic changes of reference signal functions, the reference signal pattern will change dynamically. Therefore, it is also necessary to design a variety of Different reference signal patterns. The target reference signal pattern used in the next transmission time interval is one selected from a plurality o...

Abstract

The invention discloses a reference signal indication method, a network device and a terminal device. The method comprises the steps of configuring a target reference signal pattern employed in a nexttransmission time interval for the terminal device; not sending reference signal indication information to the terminal device when the target reference signal pattern is a default reference signal pattern, or not sending the reference signal indication information to the terminal device when the target reference signal pattern is the same as the reference signal pattern indicated by the reference signal indication information received last time, wherein the target reference signal pattern is the reference signal pattern selected from a plurality of preset reference signal patterns. Accordingto the method, the network device and the terminal device, when the default reference signal pattern is employed in the next transmission time interval or the reference signal pattern the same as thereference signal pattern employed in a previous transmission time interval is employed, the reference signal indication information is not sent, on the premise of ensuring that the reference signal pattern is indicated accurately, the sending times of the system information is reduced, the bit cost of the system information is reduced, and a business transmission rate is improved.

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...
