The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided in an embodiment of the present application, as shown in fig. 1, including the following steps:

step 101, the terminal receives indication information of network equipment, wherein the network equipment is located in the NTN.

The specific manner in which the terminal receives the indication information of the network device is not limited in the embodiments of the present application. For example, the terminal may receive the indication information transmitted by the network device through the system message.

Wherein the indication information includes one or more of:

position information of the neighbor cell; beam information of the neighbor cell; information of the country to which the neighbor belongs; frequency point information of the neighboring cell; boundary information of NTN cells of the current service.

Wherein, the neighbor cell may include TN neighbor cell, NTN neighbor cell, etc. Taking a TN neighbor cell as an example, the indication information includes one or more of the following:

position information of TN neighbor cells; beam information of TN neighbor cells; information of the country to which the TN neighbor belongs; frequency point information of TN neighbor cells; boundary information of NTN cells of the current service.

In the indication information, one or more of the location information of the neighboring cell, the beam information of the neighboring cell, and the country information of the neighboring cell are carried in a neighboring cell list, for example, a same-frequency SIB3, a different-frequency SIB4, and the like.

Wherein the location information of the neighbor cell includes one or more of:

accurate location information of neighbor cells or neighbor cell base stations: for example, the information can be represented by longitude and latitude coordinates of a neighboring cell or a neighboring cell base station;

information of rough location of neighbor cells or neighbor cell base stations: for example, it may be represented by truncated coordinates of a neighbor cell or a neighbor cell base station, some bits (bits) of the coordinates (e.g., high order bits), etc.;

azimuth information of neighbor cells: for example, 12-point direction of the current NTN cell, etc.;

information of reference points of neighbor cells: the reference point may be, for example, the leftmost boundary, the rightmost boundary, the uppermost boundary, the lowermost boundary, the cell center, etc. of the neighboring cell. Optionally, if the indication information includes boundary information of the current serving NTN cell, coverage radius or diameter information of the TN neighboring cell or the NTN neighboring cell may also be included. In practical applications, the cell center is not necessarily identical to the base station, such as the case of remote radio.

Wherein the beam information of the neighbor cell includes one or more of:

beam orientation of the neighbor cell; beam width of the neighbor cell.

The boundary information of the NTN cell of the current service is carried in a broadcast message, such as SIB1 or SIB 19. The boundary information of the NTN cell of the current service includes one or more of the following:

(1) Ground information in a first range of a first boundary of an NTN cell currently being served, the ground information being used to indicate that a ground in the first range is a non-terrestrial plane;

in this case, the ground information within the first range of the first boundary of the NTN cell of the current service is represented by the boundary azimuth of the first boundary, the range information of the first range, and the information indicating the ground information.

Wherein the first boundary is any boundary of the NTN cell of the current service.

For example, as shown in fig. 2, the first boundary is the right boundary of the TN cell, the first range is a range of 30 ° each on the left and right sides of the boundary line between the rightmost boundary point of the cell and the center of the cell, the ground information is a land-free ground plane, and there may be no TN base station in the ocean, the unmanned area, or the like. 21 is shown as a terminal.

At this time, the specific indication form of the above information may be:

boundary azimuth + range information + non-terrestrial ground level or specific ground information, such as sea/unmanned area, etc.

In connection with the above examples, the above information may be expressed specifically as: right boundary +30° +non-land plane or ocean, etc. Wherein the order of the 3 parameters may be varied. Also, the meaning of this 30 ° can be described in the protocol as: a range of 30 degrees on the left and right sides of the boundary line, which is a connecting line from the rightmost boundary point of the cell to the center of the cell.

(2) There are neighbors within a second range of a second boundary of the NTN cell currently being served.

In this case, a neighbor cell exists within a second range of a second boundary of the NTN cell of the current service, and is represented by a boundary position of the second boundary, range information of the second range, and information of the neighbor cell.

Wherein the second boundary is any boundary of the NTN cell of the current service.

For example, assuming that the second boundary is a left boundary, the second range is a range in which the connecting line from the cell left boundary point to the cell center is 50 ° to the left and right of the boundary line. Alternatively, assuming that the second boundary is a right boundary, the second range is a range in which the connection line from the cell right boundary point to the cell center is 50 ° to the left and right of the boundary line.

At this time, the specific indication form of the above information may be:

boundary azimuth + range information + presence TN neighbor.

In connection with the above examples, the above information may be expressed specifically as: left boundary +50 deg. range + TN neighbor present. Wherein the order of the 3 parameters may be varied. Also, the meaning of 50 ° can be described in the protocol as: the connection line from the cell left boundary point to the cell center is in the range of 50 degrees on the left and right of the boundary line.

As shown in fig. 3 (a), the instruction information is: left boundary +50 deg. range + TN neighbor present, 31 is shown as terminal. As shown in fig. 3 (b), the instruction information is: right boundary +50 deg. range + TN neighbor present, 32 is shown as terminal.

Step 102, the terminal determines a reselection measurement candidate cell according to the indication information, or the terminal determines whether to perform neighbor cell measurement according to the indication information.

The terminal may determine the reselection measurement candidate cell in different manners according to the content included in the indication information, or determine whether to perform neighbor cell measurement.

(1) The indication information comprises position information of a neighbor cell:

The first preset value, the second preset value and the third preset value can be set according to requirements.

That is, in this case, by comparing the own position information of the terminal with the position information of the neighbor cell, it is derived whether or not the neighbor cell is to be a reselection measurement candidate cell.

And if the indication information comprises the azimuth information of the adjacent cell, the terminal takes the adjacent cell as a reselection measurement candidate cell if the terminal is currently positioned in the azimuth indicated by the azimuth information of the adjacent cell.

For example, the azimuth information of the neighbor cell is the 12-point direction of the current NTN cell. Then the terminal may determine whether it is currently located in the 12-point direction of the current NTN cell. If yes, the terminal can take the neighbor cell as a reselection measurement candidate cell.

That is, in this case, by comparing the own position information of the terminal with the azimuth indicated by the azimuth information of the neighboring cell, it is derived whether or not the neighboring cell is to be a reselection measurement candidate cell.

(2) The indication information includes beam information of the neighbor cell:

if the beam orientation of the adjacent cell is determined to be indicated to be oriented to the terminal, the terminal takes the adjacent cell as a reselection measurement candidate cell; and/or the terminal takes the neighbor cell with the beam width meeting the preset requirement as a reselection measurement candidate cell.

The preset requirement may be, for example, that the beam coverage width is greater than a certain value, or that the beam width is greater, for example, one or more neighboring cells with the beam widths ordered earlier in the plurality of neighboring cells. Assuming that there are 3 TN neighboring cells, where the beam width of TN neighboring cell 1 is the largest, the terminal may use TN neighboring cell 1 as a reselection measurement candidate cell.

(3) The indication information comprises information of a country to which the neighbor belongs:

in this case, the terminal takes a neighbor cell belonging to the same country as the terminal as the reselection measurement candidate cell. For example, if two neighboring cells belong to the same country as the terminal, the terminal uses the two neighboring cells as reselection measurement candidate cells.

(4) The indication information includes boundary information of NTN cells of the current service:

(4a) The boundary information is expressed in the following form: ground information within a first range of a first boundary of a NTN cell currently being served, the ground information being used to indicate when a ground within the first range is a non-terrestrial plane:

and if the distance between the terminal and the first boundary of the NTN cell of the current service is smaller than a fourth preset value, the terminal determines that neighbor cell measurement is not performed. The fourth preset value can be set according to requirements.

Specifically, the terminal may determine according to the distance between the current position and the first boundary, and if the distance between the terminal and the first boundary of the NTN cell currently served is smaller than a fourth preset value, the terminal determines that neighbor cell measurement is not performed, and continues to keep in the NTN network. If there is other NTN cell coverage and cell reselection is required, the terminal performs intra NTN (intra NTN system) measurements. When the distance between the current position and the first boundary is greater than a fourth preset value, the terminal can restart neighbor cell measurement (such as TN neighbor cell measurement).

As shown in fig. 2, assuming that the first boundary is the rightmost boundary, the distance between the current position of the terminal 21 and the rightmost boundary is smaller than the fourth preset value, the terminal determines that the neighbor cell measurement is not performed.

(4b) The boundary information is expressed as: when there is a neighbor in the second range of the second boundary of the NTN cell of the current service:

and if the distance between the terminal and the second boundary of the NTN cell of the current service is smaller than a fifth preset value, the terminal takes the neighbor cell in the second range as the reselection measurement candidate cell. Wherein the fifth preset value can be set according to the requirement.

Specifically, the terminal may determine according to the distance between the current position and the second boundary, and if the distance between the terminal and the second boundary of the NTN cell currently served is smaller than a fifth preset value, the terminal uses the neighbor cell in the second range as the reselection measurement candidate cell.

As shown in fig. 3 (a), the instruction information is: the left boundary +50 range + TN neighbor exists and the current position of the terminal 31 is more than a fifth preset value from the leftmost boundary, so the terminal does not need to make measurements. As shown in fig. 3 (b), the instruction information is: the right boundary+50° range+tn neighbor cells exist, and the distance from the current position of the terminal 32 to the rightmost boundary is smaller than the fifth preset value, so that the terminal needs to take the neighbor cells in the range as reselection measurement candidate cells, and needs to perform measurement.

(5) The indication information comprises frequency point information of a neighboring cell:

and if the difference value between the current frequency point of the terminal and the frequency point of the adjacent cell is smaller than a sixth preset value, the terminal takes the adjacent cell as a reselection measurement candidate cell. The sixth preset value can be set according to requirements.

(6) The indication information comprises two or more information of position information of a neighboring cell, beam information of the neighboring cell, information of a country to which the neighboring cell belongs, frequency point information of the neighboring cell and boundary information of an NTN cell of the current service:

The priority may be set as needed, for example, the priority included in the indication information may be from high to low: boundary information of the NTN cell of the current service, information of a country to which a neighbor belongs, frequency point information of the neighbor, position information of the neighbor and beam information of the neighbor.

In the above-described procedure, in the case where the instruction information includes a plurality of pieces of information, the judgment is made by sequentially using the pieces of information in order of the priority of the pieces of information from high to low. When judging by using certain information, the judging method can refer to the description of the judging method by using the information.

Starting from the highest priority information, it is assumed that a judgment result is obtained by judging from the information. If the judgment result includes more than 2 reselection measurement candidate cells, continuing to judge by using the information of the next priority on the basis of the obtained judgment result, otherwise, directly taking the judgment result as a final result. And the like until the judgment of all the information is finished, or the number of the reselection measurement candidate cells obtained when the judgment is carried out by using certain information is smaller than 2. That is, the judgment in combination with the low-priority information is performed on the basis of the judgment result obtained by the judgment in combination with the high-priority information.

For example, take the priority of the boundary information of the NTN cell of the current service, the information of the country to which the neighbor belongs, the frequency point information of the neighbor, the position information of the neighbor, and the beam information of the neighbor as an example:

(1) And judging by utilizing the boundary information of the NTN cell of the current service to obtain a judging result. If the judgment result comprises more than 2 reselection measurement candidate cells, executing the step (2), otherwise, taking the judgment result as a final result.

(2) On the basis of the judgment result obtained in (1), judgment is performed by using "information of the country to which the neighboring cell belongs" to obtain a judgment result. If the judgment result comprises more than 2 reselection measurement candidate cells, executing the step (3), otherwise, taking the judgment result as a final result.

(3) And (3) on the basis of the judgment result obtained in the step (2), judging by utilizing the frequency point information of the adjacent cell, and obtaining the judgment result. If the judgment result comprises more than 2 reselection measurement candidate cells, executing the step (4), otherwise, taking the judgment result as a final result.

(4) On the basis of the judgment result obtained in (3), judgment is performed by using the "position information of the neighboring cell" to obtain a judgment result.

(5) And (3) on the basis of the judgment result obtained in the step (4), judging by utilizing the 'beam information of the adjacent cell', obtaining a judgment result, and taking the judgment result as a final result to obtain the reselection measurement candidate cell.

The above description is made taking as an example that the indication information includes boundary information of NTN cell of the current service, information of country to which the neighbor cell belongs, frequency point information of the neighbor cell, position information of the neighbor cell, and beam information of the neighbor cell. If the indication information includes only one kind, the processing principle is the same as the above-described process principle.

Referring to fig. 4, fig. 4 is a flowchart of an information processing method provided in an embodiment of the present application, as shown in fig. 4, including the following steps:

step 401, a network device sends indication information to a terminal, wherein the network device is located in an NTN;

Wherein the indication information includes one or more of:

position information of the neighbor cell;

beam information of the neighbor cell;

information of the country to which the neighbor belongs;

frequency point information of the neighboring cell;

boundary information of NTN cells of the current service.

The meaning of each information in the above indication information may refer to the description of the foregoing embodiment.

In the following, a specific implementation process of the embodiment of the present application is described by taking information including TN neighboring cells in information indicated by the network device as an example.

Referring to fig. 5, fig. 5 is a flowchart of an information processing method provided in an embodiment of the present application. The indication information sent by the network device includes location information of the TN neighboring cell, such as information of a reference point of the TN neighboring cell. As shown in fig. 5, the method comprises the following steps:

in step 501, when the network device provides a neighbor list to the terminal, information of a reference point of the TN neighbor is added. Wherein the reference point may be a cell center.

Step 502, the terminal judges whether the distance from the current position of the terminal to the reference point of the TN neighbor cell is smaller than a threshold Th1.

Step 503, if the distance from the current position of the terminal to the reference point of the TN neighboring cell is smaller than the threshold Th1, the terminal uses the TN neighboring cell as a reselection measurement candidate cell.

And step 504, if the measured value is greater than or equal to the threshold Th1, the terminal does not perform measurement attempt on the TN neighbor cell.

Referring to fig. 6, fig. 6 is a flowchart of an information processing method provided in an embodiment of the present application. The indication information sent by the network device includes information of the own boundary of the current NTN cell. As shown in fig. 6, the method comprises the following steps:

in step 601, the network device carries boundary information of the current NTN cell in the broadcast message, for example, a right boundary +30° +non-land plane.

Step 602, the terminal determines whether the distance from the current position of the terminal to the right boundary is smaller than a threshold Th2.

If the threshold Th2 is smaller than 603, the terminal does not perform a TN cell measurement attempt, continues to keep in the NTN network, and performs intra NTN (intra NTN system) reselection measurement as needed.

Step 604, if the location information is greater than the threshold Th2, the terminal determines whether the network device provides location information of the TN neighboring cell of the current NTN cell.

Step 605, if the location information of the TN neighboring cell of the current NTN cell is provided, the TN neighboring cell that the terminal can attempt to measure may be further determined according to the provided location information of the TN neighboring cell.

The method further determines the TN neighbor cell which can be tried to be measured by the terminal according to the provided position information of the TN neighbor cell, and the method is the same as that described in other embodiments.

Referring to fig. 7, fig. 7 is a flowchart of an information processing method provided in an embodiment of the present application. The indication information sent by the network device comprises boundary information of the NTN cell which is currently served, country information of a TN neighbor cell, TN neighbor cell position information and TN neighbor cell beam information. As shown in fig. 7, the method comprises the following steps:

in step 701, the network device carries boundary information of the current NTN cell in the broadcast message, for example, the left boundary +70° + is a TN neighbor.

Step 702, the terminal determines whether the distance between the current position and the left boundary point is smaller than a threshold Th3.

In step 703, if the threshold value Th3 is smaller than the threshold value Th3, the terminal uses the corresponding TN neighboring cell as a reselection measurement candidate cell.

And step 704, if the measured value is greater than or equal to the threshold Th3, the terminal does not perform measurement attempt on the TN neighbor cell.

Step 705, if the reselection measurement candidate cell obtained in step 703 is greater than or equal to 2, the terminal determines whether the country to which the TN neighboring cell belongs is the geographic area of the same country as the terminal.

And step 706, if yes, the terminal uses the corresponding TN neighbor cell as a reselection measurement candidate cell.

Step 707, if not, the terminal does not perform measurement attempt on the TN neighboring cell.

Step 708, if the reselection measurement candidate cell obtained in step 706 is greater than or equal to 2, the terminal further determines in combination with the current location of the terminal and TN neighboring location information. Assuming that the location information of the TN neighboring cell includes information of a reference point of the TN neighboring cell, the terminal determines whether a distance between a current location of the terminal and the reference point is smaller than a threshold Th4.

Step 709, if the threshold value Th4 is smaller than the threshold value Th4, the terminal uses the corresponding TN neighboring cell as a reselection measurement candidate cell.

Step 710, if the measurement result is greater than or equal to the threshold Th4, the terminal does not perform measurement attempt on the TN neighboring cell.

In step 711, if the reselection measurement candidate cell obtained in step 709 is greater than or equal to 2, the terminal may also perform screening by combining with TN neighboring cell beam information.

For example, the terminal may consider, as the reselection measurement candidate cell, the neighbor cells of which the beam is directed toward the terminal, among the reselection measurement candidate cells obtained in step 709, or the neighbor cells of which the beam coverage is large, as the reselection measurement candidate cells.

Referring to fig. 8, fig. 8 is a flowchart of an information processing method provided in an embodiment of the present application. The indication information sent by the network equipment comprises information of a reference point of the NTN neighbor cell. As shown in fig. 8, the method comprises the following steps:

step 801, when providing a neighbor list to a terminal, the network device increases information of a reference point of an NTN neighbor. Wherein the reference point may be a cell center.

Step 802, the terminal judges whether the distance from the current position of the terminal to the reference point of the NTN neighbor cell is smaller than a threshold Th5.

Step 803, if the distance from the current position of the terminal to the reference point of the NTN neighbor cell is smaller than the threshold Th5, the terminal uses the NTN neighbor cell as a reselection measurement candidate cell.

Step 804, if the threshold Th5 is greater than or equal to the threshold Th5, the terminal does not perform measurement attempt on the NTN neighbor cell.

Referring to fig. 9, fig. 9 is a flowchart of an information processing method provided in an embodiment of the present application. The indication information sent by the network device includes beam information of the NTN neighbor cell, including: beam orientation and/or beam coverage width information of NTN neighbors. As shown in fig. 9, the method comprises the following steps:

step 901, when the network device provides a neighbor list to the terminal, adding beam information of the NTN neighbor.

Step 902, the terminal determines whether the beam of the NTN neighbor cell is directed to itself.

If yes, go to step 903; otherwise, no measurement attempt is made for the NTN neighbor cell.

Step 903, using the NTN neighbor cell as a reselection measurement candidate cell.

And 904, selecting an NTN neighbor cell with larger beam coverage width from the reselection measurement candidate cells as a final reselection measurement candidate cell.

The above has been described only by way of example with reference point information indicating that the information includes NTN neighbor cells. In practical applications, the indication information may further include other information similar to the TN neighboring cell, such as frequency point information.

According to the embodiment, by utilizing the scheme of the embodiment of the application, the terminal can be provided with some auxiliary information so as to avoid unnecessary neighbor cell measurement, further reduce the power consumption of UE cell reselection, and avoid the power consumption and time delay reduction benefits caused by increasing the limit of the number of neighbor cells in the existing measurement.
