Reselection parameter determination and indication method, communication device, and storage medium

Abstract

This disclosure relates to the field of communication technology, specifically to a method for determining and indicating cell reselection parameters, communication equipment, and storage medium. The method for determining reselection parameters includes: determining the association between incremental reselection parameters and features, and identifying features supported or of interest to the terminal; determining incremental reselection parameters associated with each feature based on the association; and re-determining reselection parameters based on traditional reselection parameters and the incremental reselection parameters associated with each feature. The re-determined reselection parameters are used for cell reselection. According to this disclosure, since the re-determined reselection parameters are related to multiple features supported or of interest to the terminal, the terminal's cell reselection based on the re-determined reselection parameters is more likely to ensure that the reselected cell meets the multiple features supported or of interest to the terminal.

[0002] Cell reselection refers to the process by which a terminal (e.g., a mobile phone) initiates a cell reselection mechanism when it detects that the signal quality of the currently serving cell has dropped below a certain threshold. The terminal attempts to find a cell with a better signal and more suitable for communication, and then switches to that cell for communication. However, some technical issues still need to be resolved in the cell reselection process. Summary of the Invention

[0065] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102, wherein the network device includes at least one of the following: an access network device and a core network device.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0070] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0071] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0072] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative.

[0073] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0074] In some embodiments, the terminal can monitor the signal quality of the serving cell. When the signal quality of the serving cell deteriorates, the terminal can measure the signal quality of neighboring cells. For example, the measured quantities include, but are not limited to, Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ).

[0075] In some embodiments, the terminal may first measure according to the priority of the frequency points (e.g., from high to low priority), for example, the frequency point may refer to the frequency corresponding to the Absolute Radio Frequency Channel Number (ARFCN).

[0076] For frequency points with relatively high priority (higher than the priority of the frequency point corresponding to the serving cell), the terminal always performs measurements on the frequency point. For frequency points with relatively low priority or the same priority (lower than or equal to the priority of the frequency point corresponding to the serving cell), the terminal can determine whether to perform measurements based on the S criterion.

[0077] For example, S serving the cell rxlev >S intrasearchP And S qual >S intrasearchQ The terminal can choose not to perform intra-frequency measurements; otherwise, the terminal can perform intra-frequency measurements.

[0078] For example, S serving the cell rxlev >S nonintrasearchP And S qual >S nonintrasearchQ The terminal can choose not to perform inter-frequency or inter-RAT (Radio Access Technology) measurements; otherwise, the terminal needs to perform the measurements.

[0079] Regarding S rxlev S intrasearchP S intrasearchQ S nonintrasearchP S nonintrasearchQ The meaning of can be found in the description of the S criterion in related technologies, and will not be repeated here.

[0080] In some embodiments, the terminal can sort cells based on measurement results and assess whether cell reselection is necessary.

[0081] For cells corresponding to frequency points with relatively high priority, the terminal can reselect to that cell as long as the signal quality is greater than a predefined threshold. For cells corresponding to frequency points with the same priority, the terminal can sort the cells based on the R criterion and select a cell for reselection based on the sorting, for example, reselecting to the cell with the highest R value.

[0082] For example, R can be determined for the serving cell based on the R criterion. s And determining R for neighboring cells n .

[0083] R s =Q meas,s +Q hyst -Qoffset temp ;

[0084] R n =Q meas,n -Qoffset-Qoffset temp .

[0085] The meanings of the relevant parameters are shown in Table 1 below: Table 1

[0086] Among them, Q meas,s Q is the RSRP measurement for the serving cell. meas,n This refers to the RSRP measurement for neighboring cells, Qoffset. s,n Qoffset refers to the offset between the serving cell and neighboring cells. frequency This refers to the offset corresponding to the frequency point. The specific definitions of the above parameters can be found in the descriptions of the S-criterion in relevant technologies, and will not be repeated here.

[0087] For cells corresponding to frequency points with relatively low priority, the terminal will only reselect the cell if the signal quality of the serving cell is lower than a predefined threshold and the signal quality of the serving cell is higher than a predefined threshold.

[0088] In some embodiments, regarding triggering cell reselection, when certain conditions are met, such as when the serving cell signal is below a certain threshold, or when there is a neighboring cell with a significantly better signal, the terminal can trigger the cell reselection process.

[0089] In some embodiments, after the terminal determines the target cell to be reselected, the terminal can perform operations such as synchronizing with the target cell and reading the system information of the target cell, and then switch to the target cell to complete the cell reselection.

[0090] As can be seen, the terminal can complete cell reselection based on frequency priority, S criterion, and R criterion. However, with the development of communication technology, the cell reselection process has become more complex.

[0091] For example, during cell reselection, it is necessary to consider the characteristics that the terminal supports or is interested in, such as the characteristics corresponding to the services the terminal needs to perform. For example, these characteristics may include at least one of the following:

[0092] High Speed ​​Dedicated Network (HSDN);

[0093] Multicast / Broadcast Service (MBS);

[0094] Direct connection links (sidelinks), such as NR (New Radio) sidelinks and V2X (Vehicle to everything) sidelinks;

[0095] Network slicing;

[0096] Non-Public Network (NPN).

[0097] For example, the priority of frequency points and cells can be determined based on the following rules, taking into account characteristics:

[0098] When an HSDN-enabled terminal is in a high-mobility state, the terminal should always treat HSDN cells as the highest priority (i.e., higher than the priority of any other network configuration). When an HSDN-enabled terminal is not in a high-mobility state, the terminal should always treat HSDN cells as the lowest priority (i.e., lower than the priority of any other network configuration).

[0099] If the terminal is configured to perform both NR sidelink and V2X sidelink communication, the terminal may consider the frequency of providing NR sidelink communication configuration and V2X boundary communication configuration as having the highest priority. If the terminal is configured to perform NR sidelink communication but not V2X communication, the terminal may consider the frequency of providing NR sidelink communication configuration as having the highest priority. If the terminal is configured to perform V2X sidelink communication but not NR sidelink communication, the terminal may consider the frequency of providing V2X sidelink communication configuration as having the highest priority.

[0100] If the terminal is configured to perform ranging / sidelink positioning, the terminal can treat the frequency configuration that provides ranging / sidelink location as the highest priority.

[0101] If a terminal that supports MBS broadcasting is receiving or is interested in receiving MBS broadcasting services, and can only receive the MBS broadcasting services by residing on the frequency that provides the services, then the terminal can consider the frequency to be of the highest priority during an MBS broadcasting session as specified in TS 38.300[2], provided that the following two conditions are met:

[0102] (1) The SIB1 scheduling information of the cell that the terminal reselects due to the frequency priority of MBS includes SIB20;

[0103] (2) One or more MBS FSAIs (Frequency Selection Area Identifications) for this frequency are indicated in the SIB21 of the serving cell, and as specified in TS26.517

[0020] , the same MBS FSAI is also indicated for the MBS broadcast service in the MBS User Service Description (USD), or

[0104] SIB21 is not provided in the serving cell, and this frequency is included in the USD of this service, or

[0105] SIB21 is provided in the serving cell, but does not provide frequency mapping for the relevant service, and the frequency is included in the USD of the service.

[0106] Note: When USD provides multiple frequencies for services of interest to the terminal, the choice of which frequency to use depends on the terminal's implementation.

[0107] If a terminal that supports MBS broadcast is receiving or is interested in receiving MBS broadcast services, the terminal may consider the cell reselection candidate frequency that it cannot receive MBS broadcast services during the MBS broadcast session specified in TS 38.300[2], provided that the SIB1 scheduling information of the cell contains SIB20 on the MBS frequency monitored by the terminal, and provided that the serving cell meets the above condition (2).

[0108] Note: Unless otherwise stated, the priority between frequencies that the terminal considers to be the highest priority frequency is implemented by the terminal.

[0109] As can be seen, in the above embodiments, for a single characteristic, the terminal can directly set the priority of the frequency corresponding to that characteristic to the highest. However, for multiple characteristics, determining the priority of the frequency corresponding to each characteristic is left to the terminal. But compared to network devices, the terminal cannot fully and accurately know the network load situation. Therefore, determining the priority of the frequency corresponding to a characteristic based on the terminal's implementation, and then performing cell reselection accordingly, is unlikely to meet the needs of network load balancing. Furthermore, the reselection parameters (e.g., Qoffset) sent by the network device in related technologies are not related to the characteristics, making it difficult for the terminal to reselect a cell that matches its required characteristics based on the reselection parameters.

[0110] Figure 2 is an interactive schematic diagram illustrating a reselection parameter determination method according to an embodiment of the present disclosure.

[0111] In some embodiments, the reselection parameter determination method can be performed by a terminal. For example, the reselection parameters can be parameters used for cell reselection.

[0112] In some embodiments, the terminal can determine the association between incremental reselection parameters and characteristics.

[0113] For example, the terminal can determine the association between incremental reselection parameters and features based on predefined rules (such as protocol agreements).

[0114] For example, as shown in Figure 2, in step S201, the network device sends indication information to the terminal. The indication information is used to indicate the association between the incremental reselection parameters and the characteristics.

[0115] In some embodiments, the indication information includes at least one of the following:

[0116] System information, such as System Information Block (SIB);

[0117] Radio Resource Control (RRC) signaling.

[0118] It should be noted that the indication information is not limited to the aforementioned SIB and RRC signaling. Network devices can also indicate the association relationship through other indication information, such as downlink control information (DCI), paging messages, and media access control control element (MAC CE). This disclosure does not limit this.

[0119] In some embodiments, the terminal may determine at least one feature (e.g., one or more features) that the terminal supports or is interested in.

[0120] For example, the features supported by a terminal can be determined based on the terminal's capabilities. For instance, if the terminal's capabilities support HSDN services, then the features supported by the terminal can be determined to include HSDN.

[0121] For example, the features that a terminal is interested in can be determined based on the services that the terminal needs to perform. For instance, if the terminal needs to perform MBS services, it can be determined that the features that the terminal is interested in include MBS.

[0122] In some embodiments, the terminal may determine the incremental reselection parameter associated with each of the at least one feature based on the association relationship.

[0123] In step S202, the terminal re-determines the re-selection parameters based on the legacy re-selection parameters and the incremental re-selection parameters associated with each of the at least one feature.

[0124] In some embodiments, reselection parameters refer to parameters applied during the cell reselection process, such as frequency priority, parameters in the S criterion, parameters in the R criterion, etc.

[0125] For example, the reselection parameters include at least one of the following:

[0126] Frequency priority;

[0127] Cell offset, such as Qoffset in the R criterion.

[0128] Traditional retransmission parameters refer to retransmission parameters already used in related technologies, which are not related to characteristics, such as frequency priority, Qoffset, etc. Traditional reselection parameters can also be called absolute reselection parameters; while incremental reselection parameters are the same type of parameters added on the basis of traditional retransmission parameters.

[0129] For example, traditional reselection parameters include the traditional priority of frequency points, while incremental reselection parameters can include the incremental priority of frequency points.

[0130] For example, traditional reselection parameters include the traditional offset of the cell, while incremental reselection parameters can include the incremental offset of the cell.

[0131] In some embodiments, the terminal can perform cell reselection based on the reselection parameters that have been redefined.

[0132] As can be seen from the preceding embodiments, traditional retransmission parameters such as frequency priority and cell offset are unrelated to characteristics, or the terminal can only determine the frequency priority based on a single characteristic. However, according to the embodiments of this disclosure, the terminal can determine the incremental reselection parameters associated with each characteristic based on the correlation relationship, and then determine the reselection parameters based on the traditional reselection parameters and the incremental reselection parameters.

[0133] Since the reselection parameters are related to multiple features that the terminal supports or is interested in, the terminal can perform cell reselection based on the reselection parameters. This is more conducive to ensuring that the reselected cell meets the multiple features that the terminal supports or is interested in. Moreover, the correlation is not determined by the terminal based on the implementation, but is indicated by the network device or specified by predefined rules. Therefore, the cell reselected in this way is more likely to meet the needs of network load balancing.

[0134] In some embodiments, the features include at least one of the following: HSDN; MBS; NR sidelink, V2X sidelink; slice; NPN.

[0135] It should be noted that the features in the embodiments of this disclosure are not limited to the above-mentioned types, and may also include other features, such as NTN (Non-Terrestrial Network), which is not limited in this disclosure.

[0136] In some embodiments, the calculation method for the terminal to re-determine the reselection parameters based on the traditional reselection parameters and the incremental reselection parameters associated with each of the at least one characteristics is not unique. The calculation method may be indicated by the network device or specified by predefined rules.

[0137] For example, the calculation method may include summation, whereby the terminal can determine that the sum of the traditional reselection parameters and the incremental reselection parameters associated with each of the at least one characteristic is equal to the newly determined reselection parameters.

[0138] It should be noted that the calculation method is not limited to summation; for example, it may include methods such as quotient calculation, and this disclosure does not limit this. The following embodiments mainly use the summation calculation method as an example to illustrate the technical solution of this disclosure.

[0139] The following examples illustrate the technical solutions of this disclosure by using several embodiments, with frequency priority and cell offset as examples, respectively.

[0140] In some embodiments, where the reselection parameters include frequency priority, the association between incremental reselection parameters and characteristics includes the association between incremental frequency priority and characteristics.

[0141] For example, the relationship between frequency priority and characteristics can be set separately for each frequency (e.g., each frequency in the candidate frequency). In this case, the relationship between frequency priority and characteristics can include the first relationship corresponding to each frequency.

[0142] Based on this, the terminal can redetermine the priority of the frequency point according to the traditional priority of the frequency point and the incremental priority determined based on the first association relationship corresponding to the frequency point.

[0143] For example, network devices can indicate the first association corresponding to each frequency point through system information or RRC signaling (such as RRC release signaling). For example, network devices can indicate the first association corresponding to each frequency point for multiple inter-frequency points in SIB4; for example, network devices can indicate the first association corresponding to each frequency point for multiple inter-RAT frequency points in SIB5.

[0144] Taking two candidate frequency points FR#1 and FR#2 as examples, FR#1 supports features including HSDN, MBS, NR sidelink, and NPN; FR#2 supports features including HSDN, MBS, V2X sidelink, and slice.

[0145] The first association corresponding to FR#1 has an incremental priority of P11 for HSDN association, P12 for MBS association, P13 for NR sidelink association, and P14 for NPN association.

[0146] The second association corresponding to FR#2 has an incremental priority of P21 for HSDN association, P22 for MBS association, P23 for V2X sidelink association, and P24 for slice association.

[0147] For example, if the traditional priority corresponding to FR#1 is P10, then the priority P1 redefined for FR#1 can be P10+P11+P12+P13+P14.

[0148] Alternatively, the terminal can determine the features it supports or is interested in from the features supported by FR#1, such as HSDN, MBS, and NPN. In this case, the terminal can determine the priority P1 redefined for FR#1 as P10+P11+P11+P14.

[0149] For example, if the traditional priority corresponding to FR#2 is P20, then the priority P2 redefined for FR#2 can be P20+P21+P21+P23+P24.

[0150] Alternatively, the terminal can determine the features it supports or is interested in from the features supported by FR#2, such as HSDN, MBS, and slice. Then the terminal can determine the priority P2 redefined for FR#2 as P20+P21+P22+P24.

[0151] Furthermore, during the cell reselection process, the terminal can perform cell reselection according to the priority of FR#1 as P1 and the priority of FR#2 as P2. For example, FR#1 and FR#2 can be measured according to P1 and P2 from large to small (or from small to large). The specific measurement process can be referred to the S criterion, R criterion, etc. in the previous embodiment, which will not be repeated here.

[0152] Since the redefined priorities P1 and P2 are related to multiple features that the terminal supports or is interested in, the terminal can perform cell reselection based on the redefined priorities P1 and P2. This is more conducive to ensuring that the reselected cell meets the multiple features that the terminal supports or is interested in. Moreover, the correlation is not determined by the terminal based on the implementation, but is indicated by the network device or specified by predefined rules. Therefore, the cell reselected accordingly is more likely to meet the needs of network load balancing.

[0153] It should be noted that, regarding the redefined priority, a larger value may indicate a higher priority, or a larger value may indicate a lower priority; this disclosure does not limit this. Furthermore, regarding the redefined priority, if the value is not an integer, it can be used as the priority, or the value can be rounded (e.g., rounded up or down), and the rounded value can be used as the priority.

[0154] In some embodiments, where the reselection parameters include the cell offset, the association between the incremental reselection parameters and the characteristics includes the association between the cell's incremental offset and the characteristics.

[0155] For example, the relationship between cell offset and characteristics can be set separately for each cell (e.g., each cell among multiple cells corresponding to a candidate frequency point). In this case, the relationship between cell offset and characteristics can include a second relationship corresponding to each cell.

[0156] Based on this, the terminal can redetermine the offset of the cell according to the traditional offset of the cell and the incremental offset determined based on the second association relationship corresponding to the cell.

[0157] For example, network devices can indicate the first association relationship corresponding to each frequency point through system information or RRC signaling (e.g., RRC release signaling). For example, network devices can indicate the second association relationship corresponding to each of multiple co-frequency neighboring cells in SIB3 (e.g., in a co-frequency neighboring cell list); for example, network devices can indicate the second association relationship corresponding to each of multiple inter-frequency neighboring cells in SIB4 (e.g., in an inter-frequency neighboring cell list).

[0158] Taking two cells, cell #1 and cell #2, as examples, cell #1 supports features including HSDN, MBS, NR sidelink, and NPN; cell #2 supports features including HSDN, MBS, V2X sidelink, and slice.

[0159] The first association corresponding to cell#1 is the incremental offset of HSDN, the incremental offset of MBS is Q12, the incremental offset of NR sidelink is Q13, and the incremental offset of NPN is Q14.

[0160] The second association corresponding to cell#2 is as follows: the incremental offset of HSDN association is Q21, the incremental offset of MBS association is Q22, the incremental offset of V2X sidelink association is Q23, and the incremental offset of slice association is Q24.

[0161] For example, if the traditional offset for cell #1 is Qoffset1, then the newly determined offset Q1 for cell #1 can be Qoffset1+Q11+Q12+Q13+Q14.

[0162] Alternatively, the terminal can determine the features it supports or is interested in from the features supported by cell#1, such as HSDN, MBS, and NPN. Then the terminal can determine the offset Q1 redefined for cell#1 as Qoffset1+Q11+Q12+Q14.

[0163] For example, if the traditional offset for cell #2 is Qoffset2, then the newly determined offset Q2 for cell #2 can be Qoffset2+Q21+Q22+Q23+Q24.

[0164] Alternatively, the terminal can determine the features it supports or is interested in from the features supported by cell#2, such as HSDN, MBS, and slice. Then the terminal can determine the offset Q1 redefined for cell#1 as Qoffset2+Q21+Q22+Q24.

[0165] Furthermore, during the cell reselection process, such as when ranking cells based on the R criterion, the terminal determines R for cell #1. n At that time, R can be replaced by Q1. n The Qoffset in the calculation formula is used to determine R for cell #2. n At that time, R can be replaced by Q2. n The Qoffset in the formula is calculated, and then cell#1 and cell#2 are sorted based on the newly determined R.

[0166] Since the redefined offsets Q1 and Q2 are related to multiple features that the terminal supports or is interested in, the terminal performs cell reselection based on the redefined offsets Q1 and Q2. This is more conducive to ensuring that the reselected cell meets the multiple features that the terminal supports or is interested in. Moreover, the correlation is not determined by the terminal based on the implementation, but is indicated by the network device or specified by predefined rules. Therefore, the cell reselected accordingly is more likely to meet the needs of network load balancing.

[0167] It should be noted that the embodiments relating to the first association and the embodiments relating to the second association can be implemented independently (e.g., only the priority of the frequency point is re-determined during the cell reselection process, or only the offset of the cell is re-determined during the cell reselection process), or they can be implemented in combination (e.g., the priority of the frequency point is re-determined during the cell reselection process, and the offset of the cell is re-determined during the cell reselection process). This disclosure does not limit them in this respect.

[0168] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.

[0169] In some embodiments, steps S201 and S202 may be performed in an alternate order or simultaneously.

[0170] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0171] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0172] In some embodiments, other alternative implementations described before or after the specification corresponding to Figure 2 may be referred to.

[0173] The technical solutions of this disclosure will be illustrated by several further embodiments below.

[0174] Example 1:

[0175] For the frequency points supported by the system, the network device is configured with an absolute reselection priority (that is, the traditional reselection priority, which is not related to any feature).

[0176] For one or more features, network devices additionally configure one or more incremental reselection priorities associated with those features. For a single feature, the final reselection priority for that frequency point = absolute reselection priority + incremental reselection priority associated with that feature. If the terminal supports or is interested in multiple features (e.g., N features), then the final reselection priority for that frequency point = absolute reselection priority + incremental reselection priority associated with feature 1 + incremental reselection priority associated with feature 2 + ... + incremental reselection priority associated with feature N.

[0177] The terminal determines the final reselection priority for each frequency point based on the features or combinations of features it supports or is interested in, and then performs the inter-frequency cell reselection process based on these reselection priorities.

[0178] For example, incremental reselection priorities can be configured on various frequency points via system messages, such as multiple inter-frequency points in SIB4 or multiple inter-RAT frequency points in SIB5; they can also be configured on various frequency points via RRC-specific signaling (such as RRC release messages). Incremental reselection priorities can be sub-priorities, where absolute reselection priorities are integers, and sub-priorities are decimals less than 1.

[0179] For example, the feature can be one of the following (including but not limited to): HSDN, MBS, NR sidelink, V2X sidelink, NPN, slicing.

[0180] Example 2:

[0181] For neighboring cells on a certain frequency point, the network device is configured with a basic cell offset (also known as a traditional cell offset, which is not related to any characteristics).

[0182] For one or more features, the network device additionally configures one or more incremental cell offsets associated with those features. For a single feature, the final cell offset of the neighboring cell = basic cell offset + incremental cell offset associated with that feature. If the terminal supports or is interested in multiple features (e.g., N features), then the final reselection priority of the neighboring cell = basic cell offset + incremental cell offset associated with feature 1 + incremental cell offset associated with feature 2 + ... + incremental cell offset associated with feature N.

[0183] The terminal determines the final cell offset of each neighboring cell based on the features or combinations of features that the terminal supports or is interested in, and then performs a cell reselection process on the same frequency or the same priority frequency based on these cell offsets.

[0184] Incremental cell offsets can be configured to each neighboring cell on each frequency point through system messages, such as the co-frequency neighboring cell list in SIB3 or the inter-frequency neighboring cell list on multiple frequency points in SIB4; they can also be configured to each neighboring cell through RRC dedicated signaling (such as RRC release messages).

[0185] Example 3:

[0186] Network devices configure feature priorities for multiple features. Feature priorities are integer values, with smaller values ​​indicating higher or lower priorities. When a terminal supports or is interested in multiple features, it uses the feature with the highest priority configured by the network to determine the final reselection priority of each frequency point (e.g., in conjunction with Example 1) and / or the final cell offset of neighboring cells (e.g., in conjunction with Example 2), thereby executing the cell reselection process.
