[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...

[0045] The above first embodiment briefly introduces the reference signal indicating method of the present invention, and the following embodiment will further introduce it in conjunction with the accompanying drawings and specific application scenarios.
[0046] Such as figure 2 As shown, the method for indicating a reference signal in the embodiment of the present invention specifically includes the following steps:
[0047] Step 21: Configure the target reference signal pattern used in the next transmission time interval for the terminal equipment.
[0048] Wherein, the reference signal pattern used in the next transmission time interval is one selected from multiple different reference signal patterns.
[0049] Among them, the target reference signal pattern is: a demodulation reference signal pattern (DMRS pattern), a channel state information measurement pilot pattern (CSI-RS pattern), a phase tracking reference signal pattern (PTRS pattern) or a channel sounding refer...

[0067] The first embodiment and the second embodiment above have respectively introduced in detail the indication methods of the reference signal in different scenarios, and the following embodiment will further introduce the corresponding network devices with reference to the accompanying drawings.
[0068] Such as image 3As shown, the network device 300 in the embodiment of the present invention can realize the configuration of the target reference signal pattern used in the next transmission time interval for the terminal device in the first embodiment and the second embodiment; when the target reference signal pattern is the default reference signal pattern, do not send reference signal indication information to the terminal device; or, when the target reference signal pattern is the same as the reference signal pattern indicated by the previous reference signal indication information, do not send reference signal indication information to the terminal device.
