Description

Method performed by user equipment and user equipment
Technical Field
The present invention relates to the field of wireless communication technology, and more particularly, to a method for performing a relaxed radio resource measurement by a user equipment and a corresponding user equipment.
Background
In NR, a CSI-rs (CSI reference signal) downlink channel state information reference signal is sent by a base station, and a terminal may receive the reference signal and is used for time-frequency tracking, measurement, and the like of an RRC connection state. The configuration of the CSI-RS may be periodic transmission, semi-persistent transmission, and aperiodic transmission. Trs (tracking Reference signal) is a CSI-RS for tracking Reference signals.
In 12 months 2019, on 3rd Generation Partnership Project (3 GPP) RAN #86, a work Project for Power Saving Enhancements to Release 17 (see non-patent document: RP-193239New WID: UE Power Saving Enhancements) was approved. The latest version of this work item is referred to non-patent literature: RP-200938 Revised WID _ UE Power Saving Enhancements for NR _ Change. The work item mainly studies how the terminal saves power in the RRC idle state and the RRC inactive state. One of the goals of the work item is to share the TRS/CSI-RS occasion for the connected state to the UEs in the idle and inactive states.
In the prior art, in the RRC idle state and the inactive state, the UE needs to monitor the PO to detect whether there is a paging message of its own. To be able to receive paging, the UE needs to wake up before the PO time and receive the SSB for synchronization. In the case of a poor radio resource environment, the UE may need to receive multiple SSBs before synchronization can be completed, so that the UE has to wake up more time ahead. In the work item aiming at the release 17 for saving power enhancement, the TRS/CSI-RS which is only used in a connected state in the prior art is shared by the UE in an idle state and an inactive state, and the UE can perform time-frequency tracking through the TRS/CSI-RS, so that synchronization is completed more quickly. In this way, the UE can receive pages without waking up too early compared to the prior art, thereby achieving the goal of power saving. The CSI-RS in the simultaneous connected state may also be shared to the UEs in the idle and inactive states for measurements in the idle and inactive states.
The present invention discusses the problems associated with achieving the CSI-RS configuration in the above-mentioned research objectives.

Stationary equipment includes equipment that is stationary at all times, equipment that is stationary for a period of time, and equipment that moves at very low speeds.
In the prior art, in the RRC idle state and the inactive state, the UE needs to monitor the PO to detect whether there is a paging message of its own. To be able to receive paging, the UE needs to wake up before the PO time and receive the SSB for synchronization. In the case of a poor radio resource environment, the UE may need to receive multiple SSBs before synchronization can be completed, so that the UE has to wake up more time ahead. In the work item aiming at the release 17 for saving power enhancement, the TRS/CSI-RS which is only used in a connected state in the prior art is shared by the UE in an idle state and an inactive state, and the UE can perform time-frequency tracking through the TRS/CSI-RS, so that synchronization is completed more quickly. In this way, the UE can receive pages without waking up too early compared to the prior art, thereby achieving the goal of power saving. The CSI-RS in the simultaneous connected state may also be shared to the UEs in the idle and inactive states for measurements in the idle and inactive states.
The TRS/CSI-RS for the idle and inactive states may be configured through RRC dedicated signaling and/or system messages. RRC-specific signaling is used to configure the UE-level configuration and system messages are used to configure the cell-level configuration. The configuration of the TRS/CSI-RS should include at least time information and frequency information of the signal. The frequency domain resource occupied by the CSI-RS may be an integer multiple of 4 resource blocks.
In the following, several embodiments of the present invention for CSI-RS configuration are described in detail.
Example 1
Fig. 1 is a flowchart illustrating a method performed by a user equipment according to embodiment 1 of the present invention.
In embodiment 1 of the present invention, a user equipment UE performs steps including: step 101, step 103, step 105, step 107.
Specifically, in step 101, configuration information related to a first reference signal is acquired.
-optionally, the first reference signal is a TRS.
-optionally, the first reference signal is a CSI-RS.
Acquiring configuration information related to the first reference signal by receiving a configuration message sent by the base station, where the configuration message may be one or more of the following:
-the configuration message is RRC dedicated signaling (e.g. rrcreelease message).
-the configuration message is a system message.
Obtaining configuration information about the first reference signal for detecting the first reference signal in one or more of:
-detecting the first reference signal in RRC idle state.
-detecting the first reference signal in the RRC inactive state.
The configuration information related to the first reference signal includes time-frequency information and control information required by the UE to detect the first reference signal, and includes one or more of the following:
-including configuration information validity duration information;
-frequency domain information comprising a first reference signal;
-time domain information comprising the first reference signal.
In step 103, configuration information relating to the first reference signal is saved.
In step 105, a first timer is started.
Optionally, starting the timer from the time when the RRC connected state enters the idle state (e.g. a RRCRelease message carrying no suspend information is received);
optionally, the timer is started from the time when the RRC connected state enters the inactive state (e.g. when a rrcreelease message carrying suspend information is received)).
In step 107, if the first timer is running, the first timer is stopped.
-optionally, stopping the first timer upon receipt of the RRCSetup message;
-optionally, stopping the first timer upon receipt of the RRCResume message;
-optionally, when the received rrcreelease message carries configuration information related to the first reference signal;
-optionally, when a cell reselection occurs and the newly selected cell is not within the system message active area.
In addition, in step 107, when the received rrcreelease message carries the configuration information related to the first reference signal, if the first timer is running, the first timer is stopped, and then the first timer is restarted according to the configuration of the first reference signal in the rrcreelease message.
The first timer stops or times out:
1) if the first reference signal configurations for the idle and inactive states obtained through RRC dedicated signaling have been preceded, these saved configurations are deleted. At this time, if there are also idle and inactive first reference signal configurations in the system message, the UE uses the first reference signal configuration in the system message.
2) If the first reference signal configurations for the idle and inactive states obtained through the system message have been preceded, these saved configurations are deleted.
Example 2
Fig. 2 is a flowchart illustrating a method performed by a user equipment according to embodiment 2 of the present invention.
