Technical field

This application belongs to the field of wireless communication technology, and specifically relates to a method for obtaining a reference location, a terminal and a network side device.

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 Orbiting (LEO) satellites, Medium earth Orbiting (MEO) satellites, Geostationary earth Orbiting (GEO) satellites and 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, location-based measurement criteria are introduced in R17 NTN. The terminal can measure based on Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ). The criteria and the location-based measurement criteria jointly determine to start neighbor cell measurement. The specific criteria are as follows: If the selected reception level value (Srxlev) of the serving cell and/or cell selection If the quality value (Squal) is greater than the threshold, and the distance between the terminal (User Equipment, UE) and the reference location of the serving cell is less than the threshold, the UE may not perform New Radio (NR) co-frequency or have equal or lower priority. Inter-frequency, or inter-frequency with lower priority (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 cell will not change within a period of time. The above reference location can be provided by system message broadcast, but for earth-moving cells , the cell moves with time, and the reference position of the serving cell also changes with time, and the above method of providing the reference position is no longer applicable.

The first reference position is the reference position of the first cell at the first time.

Of course, the first parameter may also be different according to different rules.

Among them, the reference position can be a two-dimensional position on the ground, expressed in longitude and latitude, such as ellipsoid-Point IE; it can also be a three-dimensional position, expressed in longitude, latitude and altitude, such as ellipsoidPointWithAltitude IE. Take the first-order function as an example, and take the ellipsoid-Point IE to represent the reference position as an example. This function is a function related to longitude and dimension. For example: longitude = a(t-t0)+m, latitude = b(t-t0 )+n, where a and b are the change rates of the reference position, and the change rate of the reference position is at least one, t0 is the first time, m, n are the first reference positions, and additionally, the first parameter also includes latitudeSign. The first reference position is the reference position of the first cell at the first time.

As another example, taking the ellipsoid-Point IE representing the reference position as an example, the first rule is the association between multiple ellipsoid-Point IEs and time, and the terminal determines the reference position of the first cell based on the current time.

If it is a point in time, the starting time of the period of time indicated by time m is time m-1, and the end time is time m, or a period indicated by time m The start time of time is time m and the end time is time m+1. The i-th element in the first list corresponds to the i-th element in the second list. Alternatively, the third list includes multiple elements, each element representing an ellipsoid-Point IE and a period of time associated with it.

1) The first rule applicable to the first cell;

If the network side provides the first rule, it means that the terminal needs to determine the reference position of the first cell based on the first rule, that is, the network side implicitly indicates that the first cell is an earth-moving cell.

2) The first parameter applicable to the first cell;

If the network side provides the first parameter, it means that the terminal needs to determine the reference position of the first cell based on the third parameter, that is, the network side implicitly indicates that the first cell is an earth-moving cell.

3) First indication, the first indication is used to indicate that the first cell is an earth-moving cell or not an earth-moving cell, or the first indication is used to indicate that the first cell is any one of the following item:

earth-moving cell;

Earth-fixed cell.

For example, the network side can indicate the cell type of the first cell through 1 bit. For example, when the indication field of the first indication exists and the value is true, it means that the first cell is an earth-moving cell. When the indication field of the first indication does not exist, it means that the first cell is not an earth-moving cell; or, when the indication field of the first indication has a value of 1, it means that the first cell is an earth-moving cell. When the value of the indication field of an indication is 0, it means that the first cell is not an earth-moving cell; or, when the value of the indication field of the first indication is true, it means that the first cell is an earth-moving cell. When the value of the indication field of the first indication is false, it means that the first cell is not an earth-moving cell.

For another example, the network side can indicate the type of the first cell through 1 bit. For example, when the indication field of the first indication exists and the value is 1, it means that the first cell is an earth-moving cell. When the indication field of the first indication exists and the value is 0, it means that the first cell is a quasi-fixed cell. When the indication field of the first indication does not exist, it means that the first cell is an earth-fixed cell.

During the running of the timer, the terminal does not need to determine the reference position of the first cell. When the timer times out, the terminal re-determines the reference position of the first cell. The period of time may be agreed upon by a protocol or configured by the network side.

If based on network side configuration, the terminal determines the reference location of the first cell based on the first information only when the network side configures the terminal to perform the behavior of determining the reference location of the first cell. For example, the network side can use a 1-bit indication field to configure the terminal to perform the above behavior or not. For example, when the indication field exists and the value is true, the terminal performs the above behavior. When the indication field does not exist, the terminal does not execute it.

Therefore, the reference location of the first cell can be obtained from the network side before the reference location expires, for example, at the fourth time before the reference location expires, for example, 1 second before the reference location expires. The fourth time may be greater than or equal to the time required for the terminal to obtain the reference location of the first cell from the network side. Optionally, the fourth time may be determined by protocol agreement or network side configuration or terminal implementation.
