Technical field

This application belongs to the field of communication technology, and specifically relates to a neighboring cell measurement method, terminal and network side equipment.

Background technique

1. Introduction to Non-Terrestrial Networks (NTN)

Non-terrestrial communication network refers to the network or network segment that uses satellite (Satellite) or Unmanned Aircraft System (UAS) platform (platform) or high-altitude communication platform (High-Altitude Platform System, HAPS) for transmission. Compared with Terrestrial communication systems. Satellite-based non-terrestrial communication systems have wider coverage. Typical applicable scenarios include situations where ground base stations cannot be built and ground base stations are damaged, such as continuous coverage in remote mountainous areas, deserts, oceans, and forests, or It is emergency communication when a natural disaster occurs and the ground base station is damaged.

Among them, satellites include low earth orbit (LEO) satellites, medium earth orbit (MEO) satellites, geostationary earth orbit (GEO) satellites and highly elliptical orbit (Highly Elliptical Orbiting, HEO) satellites. .

2. Cell types in non-terrestrial communication networks

There are three types of cell deployments in NTN:

Earth-moving cell: The cell (ground coverage area) moves over time.

Quasi-earth-fixed cell: A cell covers one geographical area during a period of time and a different geographical area during another period of time (for example, satellites can achieve this scenario by generating steerable beams).

Earth-fixed cell: A cell always covers the same geographical area (such as cell coverage provided by geostationary satellites).

3. Cell reselection based on location-based measurement rule

For quasi-earth-fixed cells, this application considers the introduction of location-based measurement criteria. The terminal can measure based on Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ). criteria, and location-based measurement criteria jointly determine to start neighbor cell measurement. The specific criteria are as follows: If the selection reception level value (Srxlev) and/or the cell selection quality value (Squal) of the serving cell is greater than the threshold, and the terminal (UE) The distance from the reference position of the serving cell is less than the threshold value, the UE may not perform NR intra-freq or inter-freq with equal or lower priority, or inter-RAT freq with lower priority) neighbor cell measurement. Among them, the reference location and threshold of the serving cell are broadcast by system messages.

For quasi-earth-fixed cells, the cells cover the same geographical area within a period of time, and the reference location of the cells does not change within a period of time. However, for earth-moving cells, the cells move with time, that is, the serving cells The reference position will also change with time. If the reference position fails, the terminal needs to re-obtain the reference position. Obtaining the reference position takes a certain amount of time. The existing solution does not cover whether the terminal needs to continue to perform adjacent operations during this period. Cell measurement.

Embodiment 2 (the first information includes the reference location of the serving cell last available to the terminal)

In this embodiment of the present application, optionally, in the case where the first information includes the reference location of the serving cell most recently available to the terminal, the terminal performs first frequency neighbor cell measurement based on the first information or Not performing first frequency neighbor cell measurement includes:

For example, if the first frequency is an inter-frequency or inter-system frequency with a reselection priority higher than the reselection priority of the frequency of the serving cell, that is, the terminal activates a reselection priority that has a higher reselection priority than the frequency of the serving cell. After level of inter-frequency or inter-RAT frequency measurement, if the reference location of the serving cell fails, the terminal continues to perform the first frequency measurement until the number of first frequencies measured by the terminal meets When the second preset number is reached and no neighbor cell of the first frequency satisfies the cell reselection criterion, the terminal stops measuring the neighbor cell of the first frequency.

3) The end time of the valid time. If the end time of the valid time arrives, the valid time of the reference location of the serving cell times out.

The end time may be represented by absolute time (such as UTC) or SFN.

If it is based on the network side configuration, only when the network side configures the terminal to perform the first frequency neighboring cell measurement or not to perform the first frequency neighboring cell measurement based on the first information, the terminal will perform the first frequency neighboring cell measurement or not based on the first information.

For example, the network side can use 1 bit The indication domain configures the terminal to perform the above behavior (the behavior of performing the first frequency neighbor cell measurement based on the first information or not performing the first frequency neighbor cell measurement) or not to perform it. Specifically, for example, when the indication domain exists and the value is true. ), the terminal executes the above behavior.
