Problems solved by technology

When NR is deployed in the unlicensed (unlicensed, also known as unlicensed, unlicensed) spectrum, if the UE has detected a certain cell during the measurement process, but the cell cannot periodically send synchronization signal blocks because it has not obtained the right to use the channel (Synchronization Signal and physical broadcast channel Block, referred to as SSB) or other reference signals, then the UE may think that the cell does not meet the reporting conditions and delay the measurement report of the cell, which may cause the UE to be unable to perform cell handover and interrupt the current connection

specific Embodiment 1

[0068] Specific embodiment 1: UE automatically adjusts TTT

[0069] The UE accesses the primary cell (PCell) of the serving cell deployed in the NR-U. After the RRC connection is established, the PCell can configure the measurement of the serving cell and neighboring cells for the UE. In a specific implementation, the PCell may configure the UE to measure reference signals on different frequencies through RRC signaling.

[0070] For example, it can be configured as follows: (1) Measurement ID 1 (representing measurement task 1) and its associated measurement object (Measurement Objective, MO for short) current frequency F1 and measurement event A3, which is a signal of a neighboring cell The quality is higher than the signal quality of the serving cell by a preset offset, and when configuring the measurement event A3, a specific value of the preset offset, such as -2dB, may be indicated. The signal quality may be represented by Reference Signal Received Power (Reference Signa...

specific Embodiment 2

[0080] Specific embodiment two: the base station adds candidate measurement signals

[0081] In a specific implementation, the serving base station may increase the number of configured frequencies for the same measurement identifier, so that the UE can measure the serving cell or neighboring cells on frequencies other than the current frequency after receiving the relevant configuration.

[0082] Specifically, in the prior art, when the PCell configures a neighboring cell, it usually only configures the UE to measure a reference signal on one frequency of the neighboring cell, such as a reference signal on an initial BWP. In order to ensure that the UE can effectively measure neighboring cells, in the embodiment of the present invention, the PCell may configure the neighboring cells to include a reference signal on another frequency, for example, a reference signal on a non-initial BWP, in the RRC signaling.

[0083] In a specific implementation, the base station can configur...

Abstract

The invention discloses a signal measurement control method and device, a storage medium and a terminal, and the method comprises the steps: determining a measurement task which is configured with a current frequency and a preset measurement event entering condition; according to the measurement task, measuring a reference signal on the current frequency of the cell for at least one time within apreset triggering duration; within the preset triggering duration time, if the reference signal of the cell is not measured according to the measurement timing configuration period of the reference signal, increasing the measurement times of the reference signal on the current frequency, and / or measuring the reference signals on other frequencies of the cell, the other frequencies being associatedwith the cell. Through the technical scheme provided by the invention, the accuracy of triggering the measurement report by the terminal deployed in the unlicensed spectrum can be improved, and the time delay of triggering the measurement report can be effectively reduced so as to improve the user experience.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a signal measurement control method and device, a storage medium, and a terminal. Background technique [0002] The Fifth-Generation mobile communications (5G for short) system adopts the new radio (NR) technology with large bandwidth and high speed. Among them, the maximum bandwidth of a cell can reach 400MHz, far exceeding the long-term evolution (Long Term Evaluation, LTE for short) technology stipulates a maximum cell bandwidth of 20 MHz. If all NR user equipment (User Equipment, referred to as UE) need to access the bandwidth of 400MHz when accessing the network, the cost of UE will be greatly increased, and the power consumption of UE will be increased. Therefore, a new concept "Band Width Part (BWP)" is introduced into the 5G system, which allows NR UEs to use narrowband BWP to access the 5G system and use broadband BWP to transmit services.
