Example
[0169] 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 (RLM) measurement is relaxed (for example, the network side device configures the UE with a longer RRM or RLM measurement period), 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 (CSI-RS for tracking), or TRS, used for tracking; CSI-RS (CSI-RS for L1) used to calculate the received power of the layer 1 reference signal -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-Z...

[0187] Example 2:
[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 downlink synchronization power when DRX wakes up, or the UE may be configured with RRM or RLM measurement relaxation (for example, , 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 has low measurement accuracy or quality;
[0189] Optionally, the CSI-RS may include at least one of the following: CSI-RS (CSI-RS for tracking), or TRS, used for tracking; CSI-RS (CSI-RS for L1) used to calculate the received power of the layer 1 reference signal -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);
[0191] Optionally, th...
Example
[0211] Example 3:
[0212] Step 1: The UE receives the CSI-RS configuration information in IDLE state or Inactive state sent by the base station;
[0213] Step 2: The UE performs at least one of the following according to network configuration or reconfigured CSI-RS or network configuration or reconfigured CSI-RS and SSB: time / frequency tracking, CSI calculation, Layer 1 reference signal received power calculation (L1-RSRP computation), mobility measurement, and interference measurement. Wherein, 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 (CSI-RS for tracking), or TRS, used for tracking; CSI-RS (CSI-RS for L1) used to calculate the received power of the layer 1 reference signal -RSRPcomputation); and, CSI-RS for mobility (CSI-RS for mobility);
[0215] Optionally, the CSI-RS may include at least...
