Embodiment Construction

[0094] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0095] Such as figure 1 As shown, the embodiment of the present invention provides a reference signal configuration method, which is applied to the network side device, including:

[0096] Step 11, sending the configuration information of the target reference signal to the terminal through a system message or high-level signaling;

[0097] Wherein, the target reference signal is used for at least one of: time-frequency tracking, channel state information CSI calculation, and layer 1 reference signal received power RSRP measurement;

[0098] Or, in order to avoid the conflict between the PDSCH and the target reference signal, the physical resource indicated by the configuration information cannot be used for receiving the physical downlink shared channel...

Abstract

The embodiment of the invention provides a reference signal configuration, processing method and device, network side equipment and a terminal. The method comprises sending configuration information of a target reference signal through a system message or high-level signaling, wherein the target reference signal is used for at least one of time-frequency tracking, CSI (Channel State Information) calculation and RSRP (Reference Signal Receiving Power) measurement of a layer 1; or a physical resource indicated by the configuration information cannot be used for receiving the PDSCH; or if the physical resource indicated by the configuration information is overlapped with the resource of the PDSCH received by the terminal, the physical resource indicated by the configuration information overlapped with the resource of the PDSCH cannot be used for receiving the PDSCH. In the embodiment of the invention, the target reference signal can be configured for the terminal in various states, the application range of the target reference signal is expanded, and meanwhile, the overhead of the network side equipment caused by the network side equipment sending extra information is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a reference signal configuration, processing method, device, network side equipment and terminal. Background technique [0002] Unlike 4G LTE (Long Term Evolution, long-term evolution) that uses CRS (Cell Reference Signal, cell reference signal), 5G NR (New Radio, new air interface) introduces TRS (Tracking Reference Signal, tracking reference signal) as a precise time / Estimation of large-scale channel characteristics such as frequency synchronization, delay spread and Doppler spread, etc. Currently, the TRS can only be configured through terminal-specific RRC (Radio Resource Control, radio resource control) signaling, that is, it can only be configured for the terminal in the RRC connection state. TRS is also a kind of CSI-RS (Channel State Information Reference Signal, Channel State Information Reference Signal). If in RRC signaling, a CSI-RS resource set is co...
