example 1

[0170] Step 1: The UE requests the base station to configure the CSI-RS in the Connected state. For example, the UE may be a UE that consumes a lot of power for downlink synchronization when DRX wakes up, or the UE may be configured with Radio Resource Management (RRM) Or a UE whose radio link monitoring (Radio Link Monitoring, RLM) measurement is relaxed (for example, the network side device configures a longer RRM or RLM measurement period for the UE), or the UE may only perform RRM measurement through SSB but UEs with poor measurement accuracy or quality;

[0171] Optionally, the CSI-RS may include at least one of the following: CSI-RS for tracking (CSI-RS fortracking), that is, TRS; CSI-RS for calculating layer 1 reference signal received power (CSI-RS for L1 -RSRPcomputation); and, CSI-RS for mobility (CSI-RS for mobility);

[0172] Optionally, the CSI-RS may include at least one of the following: zero-power CSI-RS (Zero Power CSI-RS), non-zero power CSI-RS (Non-Zero Pow...

[0188] Step 1: The UE requests the base station to configure the CSI-RS in the IDLE state or the Inactive state. For example, the UE may be a UE that consumes a lot of power for downlink synchronization when DRX wakes up, or the UE may be configured with RRM or RLM measurement relaxation (such as , the network side device configures the UE with a longer RRM or RLM measurement period), or the UE may be a UE that only performs RRM measurement through SSB but the measurement accuracy or quality is not high;

[0189] Optionally, the CSI-RS may include at least one of the following: CSI-RS for tracking (CSI-RS fortracking), that is, TRS; CSI-RS for calculating layer 1 reference signal received power (CSI-RS for L1 -RSRPcomputation); and, CSI-RS for mobility (CSI-RS for mobility);

[0190] Optionally, the CSI-RS may include at least one of the following: zero-power CSI-RS (Zero Power CSI-RS), non-zero power CSI-RS (Non-Zero Power CSI-RS);

[0212]Step 1: The UE receives the configuration information of the CSI-RS in the IDLE state or the Inactive state sent by the base station;

[0213] Step 2: The UE performs at least one of the following according to the CSI-RS configured or reconfigured by the network or the CSI-RS and SSB configured or reconfigured by the network: time / frequency tracking (time / frequency tracking), CSI calculation (CSIcomputation), Layer 1 reference signal received power calculation (L1-RSRP computation), mobility measurement, and interference measurement. Wherein, the time-frequency domain tracking includes time-domain tracking, frequency-domain tracking, and at least one of time-domain and frequency-domain tracking.

[0214] Optionally, the CSI-RS may include at least one of the following: CSI-RS for tracking (CSI-RS fortracking), that is, TRS; CSI-RS for calculating layer 1 reference signal received power (CSI-RS for L1 -RSRPcomputation); and, CSI-RS for mobility (CSI-RS for mobility);

Abstract

The embodiment of the invention provides a signal processing method and device. The method comprises: sending a first message to a network side device, the first message being used for requesting to configure a first CSI-RS in a connected state, an idle state or an inactive state for a terminal device, or used for requesting to configure a first configuration parameter of the first CSI-RS in the connected state, the idle state or the inactive state for the terminal device; receiving feedback information of the first message from network side equipment; and performing signal processing according to the first CSI-RS, or performing signal processing according to the first CSI-RS and a synchronization signal block SSB. According to the embodiment of the invention, the terminal equipment can quickly complete downlink synchronization through the CSI-RS or through the CSI-RS and the SSB, thereby reducing the downlink synchronization power consumption and the downlink synchronization time, andfacilitating the power saving of the terminal equipment.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal processing method and device. Background technique [0002] Currently, the new radio (NEW Radio, NR) version 15 (release 15, R15) protocol specifies the configuration of the Channel State Information Reference Signal (CSI-RS): [0003] The radio resource control (Radio Resource Control, RRC) idle (IDLE) or RRC inactive (Inactive) state does not support the configuration of CSI-RS, for example, tracking reference signal (Tracking Reference Signal, TRS); [0004] The RRC connection (Connected) state supports the configuration of CSI-RS, for example, TRS, the minimum period of TRS is 10 milliseconds (ms), and the TRS burst (burst) consists of 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols. , and sent in 2 consecutive time slots. [0005] During the development and testing of the NR user equipment (User Equipment, UE) protot...
