This application claims priority from a Chinese patent application filed on August 9, 2018 with the Chinese Patent Office, application number 201810905157.7, and application name "Method and Device for Determining Target Cells", the entire contents of which are incorporated herein by reference .

Technical field

The present application relates to the field of communication technologies, and more particularly, to a method and apparatus for determining a target cell.

Background technique

As the terminal moves, the terminal may reselect from the current cell to another cell. Therefore, the terminal needs to select a target cell that needs to be reselected.

At present, when a terminal selects a target cell from cells with the same priority, only the number of good beams in the cell and the ranking criterion value are considered. But a cell with many good beams is not necessarily a suitable target cell. Therefore, how to better select the target cell is an urgent problem.

Summary of the invention

The present application provides a method and device for determining a target cell, which can reduce the problem that the selected target cell is not an appropriate target cell due to the selection of the target cell based only on the ranking criterion value and the number of good beams.

In a first aspect, an embodiment of the present application provides a method for determining a target cell. The method includes: determining a ranking criterion value of each cell in at least one cell having the same priority; and determining whether a cell frequency of the first cell meets a preset Condition, wherein the first cell is a cell with the highest ranking criterion value among the at least one cell; and if the determination result is yes, determining that the first cell is a target cell for cell reselection. In some cases, the number of beams in cells of different frequencies is also different. Therefore, if a target cell is selected according to the number of good beams, it is disadvantageous to a cell with a small number of beams. In some cases, a cell with a small number of beams may be more suitable as a target cell than a cell with a large number of beams. When determining the target cell in the above technical solution, the cell frequency is considered. Therefore, the problem that the selected target cell is not an appropriate target cell due to selecting the target cell based on the ranking criterion value and the number of good beams is reduced.

With reference to the first aspect, in a possible implementation manner of the first aspect, before determining whether the cell frequency of the first cell meets a preset condition, the method further includes: determining that a preset for determining a similar cell is obtained value.

With reference to the first aspect, in a possible implementation manner of the first aspect, determining whether the cell frequency of the first cell satisfies a preset condition includes: determining whether the cell frequency of the first cell is not greater than the preset frequency. Generally, for low-frequency cells, the beams sent by the network device tend to be wider, but the number of beams is small (for example, only one omnidirectional beam can be sent). For high-frequency cells, the beams sent by network equipment are often narrower and larger in number. Therefore, if a low-frequency cell and a high-frequency cell have the same priority, and a low-frequency cell and a high-frequency cell are identified as similar cells according to the existing mechanism, then when the target cell is reselected by a good number of beams, the low-frequency cell Has a great disadvantage. In the above technical solution, the occurrence of the above problems is reduced. In the above technical solution, if a low-frequency cell has the highest ranking criterion value, the low-frequency cell may be directly selected as a target cell. In this way, it is possible to reduce the situation that is not conducive to being selected as the target cell due to the small number of beams in the low-frequency cell.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: if the determination result is no, determining a second cell as the target cell, where the second cell is a similar cell The cell with the best number of good beams.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: if the determination result is no, determining whether a nearby cell includes a cell that meets the preset condition; and when the determination result is In the case of yes, it is determined that the cell with the highest ranking criterion value among the cells satisfying the preset condition is the target cell; or, if the determination result is no, the third cell is determined as the target cell, where the third cell It is the cell with the largest number of good beams among the similar cells.

With reference to the first aspect, in a possible implementation manner of the first aspect, a cell satisfying the preset condition is a cell whose cell frequency is one frequency in a frequency set, where the frequency set includes at least one frequency.

With reference to the first aspect, in a possible implementation manner of the first aspect, a cell satisfying the preset condition is a cell whose cell frequency is within a frequency segment range of a frequency segment set, where the frequency segment set includes at least one Frequency band.

In the above technical solution, the number of beams of a cell within a range of a cell frequency in a frequency set or a frequency segment set may be less than the number of beams of a cell whose cell frequency is not in the frequency set or the frequency segment set. The cell frequency is within the range of the frequency set or the frequency segment set. The cell and the cell frequency are not in the frequency set or the frequency range set. According to the existing mechanism, the cell is considered to be a similar cell. In the case of a cell, a cell having a cell frequency within the frequency set or the frequency segment set has a great disadvantage. In the above technical solution, the occurrence of the above problems is reduced. If the ranking criterion value of a cell whose frequency is within the frequency set or the frequency segment set is the highest, the cell can be selected as the target cell. In this way, it is possible to reduce the situation that is not conducive to the cell being selected as the target cell due to the small number of beams in the cell.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: determining that a cell satisfying the preset condition does not participate in a better number of beams.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: receiving instruction information sent by a network device, where the instruction information is used to indicate that a cell satisfying the preset condition does not participate in a better number of beams .

In a second aspect, an embodiment of the present application provides a method for determining a target cell. The method includes: determining a ranking criterion value of each cell in at least one cell having the same priority; and determining whether at least one similar cell includes a preset cell that satisfies a preset Conditional cell; if the determination result is yes, determine the cell with the highest ranking criterion value among the cells that meet the preset conditions as the target cell for cell reselection; if the determination result is no, determine that the target cell is The cell with the largest number of good beams in the at least one similar cell. In some cases, the number of beams in cells of different frequencies is also different. Therefore, if a target cell is selected according to the number of good beams, it is disadvantageous to a cell with a small number of beams. In some cases, a cell with a small number of beams may be more suitable as a target cell than a cell with a large number of beams. When determining the target cell in the foregoing technical solution, the problem that the selected target cell is not an appropriate target cell caused by selecting the target cell only based on the ranking criterion value and the number of good beams is reduced.

With reference to the second aspect, in a possible implementation manner of the second aspect, the cell satisfying the preset condition is a cell whose cell frequency is one frequency in a frequency set, where the frequency set includes at least one frequency.

With reference to the second aspect, in a possible implementation manner of the second aspect, the cell that satisfies a preset condition is a cell whose frequency is within a frequency band range in a frequency band set.

In the above technical solution, the number of beams of a cell within a range of a cell frequency in a frequency set or a frequency segment set may be less than the number of beams of a cell whose cell frequency is not in the frequency set or the frequency segment set. The cell frequency is within the range of the frequency set or the frequency segment set. The cell and the cell frequency are not in the frequency set or the frequency range set. According to the existing mechanism, the cell is considered to be a similar cell. In the case of a cell, a cell having a cell frequency within the frequency set or the frequency segment set has a great disadvantage. In the above technical solution, the occurrence of the above problems is reduced. If the ranking criterion value of a cell whose frequency is within the frequency set or the frequency segment set is the highest, the cell can be selected as the target cell. In this way, it is possible to reduce the situation that is not conducive to the cell being selected as the target cell due to the small number of beams in the cell.

With reference to the second aspect, in a possible implementation manner of the second aspect, the cell satisfying the preset condition is a cell whose cell frequency is less than or equal to the preset frequency. Generally, for low-frequency cells, the beams sent by the network device tend to be wider, but the number of beams is small (for example, only one omnidirectional beam can be sent). For high-frequency cells, the beams sent by network equipment are often narrower and larger in number. Therefore, if a low-frequency cell and a high-frequency cell have the same priority, and a low-frequency cell and a high-frequency cell are identified as similar cells according to the existing mechanism, then when the target cell is reselected by a good number of beams, the low-frequency cell Has a great disadvantage. In the above technical solution, the occurrence of the above problems is reduced. In the above technical solution, if there is a low-frequency cell in a nearby cell, the low-frequency cell can be directly selected as the target cell. If there are multiple low-frequency cells in a similar cell, the low-frequency cell with the highest ranking criterion value among the multiple low-frequency cells can be used as the target cell. In this way, it is possible to reduce the situation that is not conducive to being selected as the target cell due to the small number of beams in the low-frequency cell.

In a third aspect, an embodiment of the present application provides a method for determining a target cell. The method includes: determining a priority of a low frequency frequency; determining a priority of a high frequency frequency, wherein the priority of the low frequency frequency and the priority of the high frequency frequency The levels are different; sending priority indication information to the terminal, the priority indication information is used to indicate the priority of the low frequency and the priority of the high frequency.

Generally, for low-frequency cells, the beams sent by the network device tend to be wider, but the number of beams is small (for example, only one omnidirectional beam can be sent). For high-frequency cells, the beams sent by network equipment are often narrower and larger in number. Therefore, if a low-frequency cell and a high-frequency cell have the same priority, and a low-frequency cell and a high-frequency cell are identified as similar cells according to the existing mechanism, then when the target cell is reselected by a good number of beams, the low-frequency cell Has a great disadvantage. In the above technical solution, the network device directly sets the priority of the low-frequency frequency to be different from the priority of the high-frequency frequency. In this case, the priority of the low frequency cell is different from the priority of the high frequency cell. In this way, the situation that the priority of the low-frequency cell is the same as that of the high-frequency cell, which is disadvantageous to the selection of the low-frequency cell as the target cell, can be reduced.

In some cases, the number of beams in cells of different frequencies is also different. Therefore, if a target cell is selected according to the number of good beams, it is disadvantageous to a cell with a small number of beams. In some cases, a cell with a small number of beams may be more suitable as a target cell than a cell with a large number of beams. When determining the target cell in the above technical solution, the cell frequency is considered. Therefore, the problem that the selected target cell is not an appropriate target cell due to selecting the target cell based on the ranking criterion value and the number of good beams is reduced.

In order to help those skilled in the art to better understand the technical solutions of the present application, first introduce some concepts involved in the embodiments of the present application.

The beam referred to in the embodiment of the present application can be understood as a space resource, and can refer to sending or receiving a precoding vector with directivity of energy transmission. The transmitted or received precoding vector can be identified by index information. The index information may correspond to a resource identifier (identity, ID) of a configuration terminal. For example, the index information may correspond to a configured identifier or resource of a channel state information reference signal (CSI-RS); it may also correspond to The configured synchronization signal / Physical Broadcast Channel Block (SS (Synchronization Signal)) / PBCH (Block, SSB) identifier or resource; or the corresponding configured uplink sounding reference signal (SRS) identifier or resource. Optionally, the index information may also be index information displayed or implicitly carried by a signal or channel carried by a beam. The energy transmission directivity may refer to precoding processing of a signal to be transmitted through the precoding vector. The signal after the precoding processing has a certain spatial directivity, and the signal received after the precoding processing is performed on the precoding vector. It has better receiving power, such as satisfying the receiving demodulation signal-to-noise ratio, etc .; the energy transmission directivity can also mean that the same signal sent from different spatial locations received by the precoding vector has different receiving power. Optionally, the same communication device (such as a terminal or a network device) may have different precoding vectors, and different devices may also have different precoding vectors, that is, corresponding to different beams. With regard to the configuration or capability of a communication device, one communication device may use one or more of a plurality of different precoding vectors at the same time, that is, one beam or multiple beams may be formed at the same time.

FIG. 1 is a schematic flowchart of a method for determining a target cell according to an embodiment of the present application. When describing the method shown in FIG. 1, some steps are described with the terminal as an execution subject, but this is only to facilitate the description of the method shown in FIG. 1. The method shown in FIG. 1 may be implemented by a terminal, and may also be implemented by a component (such as a chip or a circuit) available to the terminal. The terminal may be in an idle state or an inactive state.

101. Determine a ranking criterion value of each cell in at least one cell with the same priority.

Ranking criteria values can also be called ranking values, R values, and so on. It can be understood that the ranking criterion value here is a value used for ranking a cell during a cell reselection process. For the serving cell of the terminal, the ranking criterion value can be determined according to the following formula:

R _s = Q _{meas, s} + Qhyst, (Equation 1.1)

Among them, R _s represents the ranking criterion value of the serving cell of the terminal, Q _{meas, s} represents the received signal strength value of the serving cell of the terminal, and Qhyst represents the hysteresis value. The received signal strength value herein may refer to a reference signal receiving power (reference signal receiving power, RSRP) measurement quantity.

For the neighboring cells of the terminal's serving cell, the ranking criterion value can be determined according to the following formula:

R _n = Q _{meas, n} -Qoffset, (Equation 1.2)

Wherein, R _n represents a ranking criterion value of a neighboring cell of the serving cell of the terminal, and Q _{meas, n} represents a received signal strength value of the neighboring cell of the serving cell of the terminal. If the serving cell of the terminal device has a different frequency from the neighboring cell of the terminal device, the value of Qoffset is Qoffset _{s, n} , and if the value of Qoffset _{s, n is} invalid, the value of Qoffset is 0. If the serving cell of the terminal device has the same frequency as the neighboring cell of the terminal device, the value of Qoffset is Qoffset _{s, n} + Qoffset _frequency , and if the value of Qoffset _{s, n} is invalid, the value of Qoffset is Qoffset _frequency . Qoffset _{s, n} represents a cell-level offset, and Qoffset _frequency represents a frequency-level offset.

Optionally, in other embodiments, because the evolution of the communication protocol version is used to determine the ranking criterion value formula may change due to some reasons, the formula given here is only an example, and does not limit the formula itself.

102. Determine whether a cell frequency of the first cell meets a preset condition, where the first cell is a cell with a highest cell ranking criterion value among the at least one cell.

103. If the determination result is yes, determine that the first cell is a target cell for cell reselection.

After determining the target cell, the terminal may reselect to the target cell. Alternatively, the terminal may determine the cell status (cell status) of the target cell before or after reselecting to the target cell. Access is prohibited, and the terminal will perform cell selection or cell reselection.

In some cases, the number of beams in cells of different frequencies is also different. Therefore, if a target cell is selected according to the number of good beams, it is disadvantageous to a cell with a small number of beams. In some cases, a cell with a small number of beams may be more suitable as a target cell than a cell with a large number of beams. When the method shown in FIG. 1 determines the target cell, the cell frequency is taken into account. Therefore, the problem that the selected target cell is not an appropriate target cell due to selecting the target cell based on the ranking criterion value and the number of good beams is reduced.

Optionally, in some embodiments, before step 102, the method may further include: determining to obtain a preset value for determining a similar cell. Optionally, in some embodiments, the absolute value of the difference between the ranking criterion value of the similar cell and the first cell is smaller than the preset value. Optionally, in other embodiments, the absolute value of the difference between the ranking criterion values of the similar cell and the first cell is less than or equal to the preset value. Optionally, in some embodiments, the preset value may also be referred to as an optimal cell range (rangeToBestCell), and may also be referred to as an offset value (offset). If the preset value is not obtained, the first cell may be directly determined as the target cell.

Optionally, in some embodiments, determining whether the cell frequency of the first cell meets a preset condition includes determining whether the cell frequency of the first cell is not greater than the preset frequency. In other words, if the cell frequency of the first cell is less than or equal to the preset frequency, it is determined that the first cell is the target cell.

Optionally, in some embodiments, a cell with a cell frequency not greater than the preset frequency may be referred to as a low-frequency cell, and a cell with a cell frequency greater than the preset high-frequency frequency may be referred to as a high-frequency cell. Optionally, in some embodiments, the preset frequency may be any one of 450 MHz to 6000 MHz, for example, it may be 6000 MHz. The preset high frequency can be any of 24250MHz to 52600MHz.

Generally, for low-frequency cells, the beams sent by the network device tend to be wider, but the number of beams is small (for example, only one omnidirectional beam can be sent). For high-frequency cells, the beams sent by network equipment are often narrower and larger in number. Therefore, if a low-frequency cell and a high-frequency cell have the same priority, and a low-frequency cell and a high-frequency cell are identified as similar cells according to the existing mechanism, then when the target cell is reselected by a good number of beams, the low-frequency cell Has a great disadvantage. In the above technical solution, the occurrence of the above problems is reduced. In the above technical solution, if a low-frequency cell has the highest ranking criterion value, the low-frequency cell may be directly selected as a target cell. In this way, it is possible to reduce the situation that is not conducive to being selected as the target cell due to the small number of beams in the low-frequency cell.

Optionally, in some embodiments, the preset frequency may be pre-stored in the terminal. Optionally, in other embodiments, the preset frequency may be sent by the network device to the terminal.

If the cell frequency of the first cell is greater than the preset frequency and the preset value is obtained, it can be determined that the cell with the highest number of good beams among at least one similar cell is the target cell. If the cell with the highest number of good beams in the at least one similar cell includes two or more, the target cell is the cell with the highest number of good beams and the highest ranking criterion value.

Optionally, in some embodiments, the method shown in FIG. 1 may further include: if the determination result is no, determining a second cell as the target cell, where the second cell is the at least one neighboring cell The cell with the best number of good beams.

Optionally, in some embodiments, the method shown in FIG. 1 may further include: if the determination result is no, determining whether a nearby cell includes a cell that satisfies the preset condition; and when the determination result is yes Next, it is determined that the cell with the highest ranking criterion value among the cells satisfying the preset condition is the target cell; when the determination result is yes, the third cell is determined as the target cell, where the third cell is the at least one similar The cell with the highest number of good beams in the cell.

Optionally, in some embodiments, the cell satisfying the preset condition is a cell whose cell frequency is one frequency in a frequency set, where the frequency set includes at least one frequency. Optionally, in some embodiments, the frequency set may be preset in the terminal. Optionally, in other embodiments, the frequency set may be sent to the terminal by a network device. Optionally, in some embodiments, if the terminal receives the frequency set sent by the network device, the terminal may determine the target cell according to the method shown in FIG. 1; if the terminal does not receive the frequency device If the frequency set is sent, the terminal may determine the target cell according to a method in the prior art.

Optionally, in other embodiments, the cell that satisfies the preset condition is a cell whose cell frequency is within a frequency range in a frequency range set, where the frequency range set includes at least one frequency range. Optionally, in some embodiments, the frequency band set may be preset in the terminal. Optionally, in other embodiments, the frequency band set may be sent to the terminal by a network device. Optionally, in some embodiments, if the terminal receives the frequency segment set sent by the network device, the terminal may determine the target cell according to the method shown in FIG. 1; if the terminal does not receive the target cell by the network For the set of frequency bands sent by the device, the terminal may determine the target cell according to a method in the prior art.

In the above technical solution, the number of beams of a cell within a range of a cell frequency in a frequency set or a frequency segment set may be less than the number of beams of a cell whose cell frequency is not in the frequency set or the frequency segment set. The cell frequency is within the range of the frequency set or the frequency segment set. The cell and the cell frequency are not in the frequency set or the frequency range set are considered to be similar cells according to the existing mechanism, then the reselection target is determined by the number of good beams. In the case of a cell, a cell having a cell frequency within the frequency set or the frequency segment set has a great disadvantage. In the above technical solution, the occurrence of the above problems is reduced. If the ranking criterion value of a cell whose frequency is within the frequency set or the frequency segment set is the highest, the cell can be selected as the target cell. In this way, it is possible to reduce the situation that is not conducive to the cell being selected as the target cell due to the small number of beams in the cell.

FIG. 2 is a schematic flowchart of a method for determining a target cell according to an embodiment of the present application. In describing the method shown in FIG. 2, some steps are described with the terminal as an execution subject, but this is only for the convenience of describing the method shown in FIG. 2. The method shown in FIG. 2 may be implemented by a terminal, and may also be implemented by a component (such as a chip or a circuit) available to the terminal.

201. Determine a ranking criterion value of each cell in at least one cell with the same priority.

202. Determine whether at least one similar cell includes a cell that meets a preset condition.

203. If the determination result is yes, determine that the cell with the highest ranking criterion value among the cells that meet the preset conditions is the target cell for cell reselection.

204. If the determination result is no, determine that the target cell is the cell with the best number of good beams among the at least one similar cell.

After determining the target cell, the terminal may reselect to the target cell. Alternatively, the terminal may determine the cell status (cell status) of the target cell before or after reselecting to the target cell. Access is prohibited, and the terminal will perform cell selection or cell reselection.

For the definition of a similar cell, reference may be made to the embodiment shown in FIG. 1, which need not be repeated here.

In some cases, the number of beams in cells of different frequencies is also different. Therefore, if a target cell is selected according to the number of good beams, it is disadvantageous to a cell with a small number of beams. In some cases, a cell with a small number of beams may be more suitable as a target cell than a cell with a large number of beams. When the method shown in FIG. 2 determines the target cell, the problem that the selected target cell is not a suitable target cell due to the selection of the target cell based on the ranking criterion value and the number of good beams is reduced.

Optionally, in some embodiments, the cell satisfying the preset condition is a cell whose cell frequency is one frequency in a frequency set, where the frequency set includes at least one frequency. Optionally, in some embodiments, the frequency set may be preset in the terminal. Optionally, in other embodiments, the frequency set may be sent to the terminal by a network device. Optionally, in some embodiments, if the terminal receives the frequency set sent by the network device, the terminal can determine the target cell according to the method shown in FIG. 2; if the terminal does not receive the network device, If the frequency set is sent, the terminal may determine the target cell according to a method in the prior art.

Optionally, in other embodiments, the cell satisfying the preset condition is a cell whose cell frequency is within a frequency band range in a frequency band set. Optionally, in some embodiments, the frequency band set may be preset in the terminal. Optionally, in other embodiments, the frequency band set may be sent to the terminal by a network device. Optionally, in some embodiments, if the terminal receives the set of frequency bands sent by the network device, the terminal may determine the target cell according to the method shown in FIG. 2; For the set of frequency bands sent by the device, the terminal may determine the target cell according to a method in the prior art.

Optionally, in other embodiments, the cell satisfying the preset condition is a cell whose cell frequency is lower than or equal to the preset frequency.

Optionally, in some embodiments, in some embodiments, the preset frequency may be any one of 450 MHz to 6000 MHz, for example, it may be 6000 MHz.

Optionally, in some embodiments, the preset frequency may be pre-stored in the terminal. Optionally, in other embodiments, the preset frequency may be sent by the network device to the terminal.

In the above technical solution, the number of beams of a cell that meets the preset condition may be less than the number of beams of a cell that does not meet the preset condition. Cells that meet the preset condition and cells that do not meet the preset condition are considered to be similar cells according to the existing mechanism, so when the target cell is reselected by a good number of beams, the cell that meets the preset condition has a large Disadvantage. In the above technical solution, the occurrence of the above problems is reduced. A cell can be selected as a target cell if the frequency of a cell is the highest in the frequency set, or in the frequency band set range, or a cell that is less than a preset frequency. In this way, it is possible to reduce the situation that is not conducive to the cell being selected as the target cell due to the small number of beams in the cell.

FIG. 3 is a schematic flowchart of a method for determining a cell priority according to an embodiment of the present application. The method shown in FIG. 3 may be implemented by a network device, and may also be implemented by a component (such as a chip or a circuit) applicable to the network device.

301. Determine a priority of a low frequency.

302. Determine a priority of a high-frequency frequency, wherein a priority of the low-frequency frequency is different from a priority of the high-frequency frequency.

303. Send priority indication information to the terminal, where the priority indication information is used to indicate the priority of the low frequency and the priority of the high frequency.

Generally, for low-frequency cells, the beams sent by the network device tend to be wider, but the number of beams is small (for example, only one omnidirectional beam can be sent). For high-frequency cells, the beams sent by network equipment are often narrower and larger in number. Therefore, if a low-frequency cell and a high-frequency cell have the same priority, and a low-frequency cell and a high-frequency cell are identified as similar cells according to the existing mechanism, then when the target cell is reselected by a good number of beams, Has a great disadvantage. In the above technical solution, the network device directly sets the priority of the low-frequency frequency to be different from the priority of the high-frequency frequency. In this case, the priority of the low frequency cell is different from the priority of the high frequency cell. In this way, the situation that the priority of the low-frequency cell is the same as that of the high-frequency cell, which is disadvantageous to the selection of the low-frequency cell as the target cell, can be reduced.

For the definition of a similar cell, reference may be made to the embodiment shown in FIG. 1, which need not be repeated here.

Optionally, in some embodiments, a cell whose cell frequency is not greater than the preset frequency may be referred to as a low-frequency cell. Optionally, in some embodiments, the preset frequency may be any one of 450 MHz to 6000 MHz, for example, it may be 6000 MHz. A cell with a cell frequency greater than a preset high-frequency frequency may be referred to as a high-frequency cell. The preset high frequency can be any of 24250MHz to 52600MHz.

Optionally, in some embodiments, the preset frequency and the preset high-frequency frequency may be pre-stored in the terminal. Optionally, in other embodiments, the preset frequency and the preset high-frequency frequency may be sent by the network device to the terminal.

Optionally, in some embodiments, the priorities of all low-frequency frequencies may be the same, and the priorities of all high-frequency frequencies may be the same. In other words, the frequencies having frequencies less than or equal to the preset frequency all have the same priority. The frequencies with frequencies greater than the preset frequency have the same priority. For example, suppose the five frequencies are f1, f2, f3, f4, and f5. f1 to f3 are all smaller than or equal to the preset frequency, and f4 and f5 are both larger than the preset frequency. The priorities of the frequencies f1 to f3 may be priority 1, and the priorities of the frequencies f4 and f5 may be priority 2. Priority 1 and 2 are not the same.

Optionally, in some embodiments, the priorities of different low-frequency frequencies may be different, and the priorities of different high-frequency frequencies may be different. For example, suppose the five frequencies are f1, f2, f3, f4, and f5. f1 to f3 are all smaller than or equal to the preset frequency, and f4 and f5 are both larger than the preset frequency. The priority of frequency f1 can be priority 1, the priority of frequency f2 can be priority 2, the priority of frequency f3 can be priority 3, the priority of frequency f4 can be priority 4, and the priority of frequency f5 can be For priority 5. Priority 1, Priority 2, Priority 3, Priority 4, and Priority 5 are all different.

Optionally, in some embodiments, priorities of frequencies belonging to different frequency bands in the low-frequency frequency may be different, and priorities of frequencies belonging to different frequency bands in the high-frequency frequency may be different. For example, suppose the six frequencies are f1, f2, f3, f4, f5, and f6. f1 to f3 are all less than or equal to the preset frequency, and f4 to f6 are all greater than the preset frequency. Assume that f1 and f2 are in the first frequency range, f3 is in the second frequency range, f4 and f5 are in the third frequency range, and f6 is in the fourth frequency range. In this case, the priority of the frequency in the first frequency range may be priority 1, the priority of the frequency in the second frequency range may be priority 2, and the frequency in the third frequency range The priority of may be priority 3, and the priority of frequencies in the fourth frequency band may be priority 4. Priority 1, Priority 2, Priority 3, and Priority 4 are all different.

Optionally, in some embodiments, the way for sending priority indication information to the terminal may be sending to all cells through a broadcast message. In this way, all terminals receiving the broadcast message can perform cell reselection according to the priority indication information.

Optionally, in other embodiments, the priority indication information sent to the terminal may be sent to one or more designated terminals through dedicated signaling. In this way, only the terminal receiving the dedicated signaling can perform cell reselection according to the priority indication information.

FIG. 4 is a schematic flowchart of a method for determining a target cell according to an embodiment of the present application. In describing the method shown in FIG. 4, the description of some steps is described with the terminal as an execution subject, but this is only to facilitate the description of the method shown in FIG. 4.

402. Determine the number of good beams of each candidate cell in the at least one candidate cell as a first value, where the at least one cell includes the candidate cell, a cell frequency of the candidate cell meets a preset condition, and the first value is greater than or A positive integer equal to 1.

403. Determine that the target cell for cell reselection is a cell with the largest number of good beams in at least one similar cell.

For the definition of a similar cell, reference may be made to the embodiment shown in FIG. 1, which need not be repeated here.

After determining the target cell, the terminal may reselect to the target cell. Alternatively, the terminal may determine the cell status (cell status) of the target cell before or after reselecting to the target cell. Access is prohibited, and the terminal will perform cell selection or cell reselection.

In some cases, the number of beams in cells of different frequencies is also different. Therefore, if a target cell is selected according to the number of good beams, it is disadvantageous to a cell with a small number of beams. In some cases, a cell with a small number of beams may be more suitable as a target cell than a cell with a large number of beams. When the method shown in FIG. 4 determines the target cell, the cell frequency is considered. Therefore, the problem that the selected target cell is not an appropriate target cell due to selecting the target cell based on the ranking criterion value and the number of good beams is reduced.

Optionally, in some embodiments, the first value is the number of good beams of the cell with the largest number of good beams in the at least one cell.

Optionally, in some embodiments, the first value is an upper limit of the number of beams higher than a threshold for determining cell quality. Specifically, the network device may be configured to the terminal to generate the number of beams M of cell quality. The terminal generates the cell quality according to a maximum of M beams whose beam quality is higher than a preset threshold. For example, suppose the number of beams above the preset threshold in a cell is 8, and the value of M is 3. Then the terminal determines the cell quality according to the three beams with the highest beam quality.

Optionally, in other embodiments, the second value is a second preset value.

Optionally, in some embodiments, before determining that the number of good beams of each candidate cell in the at least one candidate cell is a first value, the method further includes: receiving the second value sent by a network device.

Optionally, in some embodiments, the cell satisfying the preset condition is a cell whose cell frequency is one frequency in a frequency set, where the frequency set includes at least one frequency.

Optionally, in some embodiments, the cell that satisfies the preset condition is a cell whose cell frequency is within a frequency band range of a frequency band set, where the frequency band set includes at least one frequency band.

Optionally, in some embodiments, if the network device is not configured with a preset value, the target cell is a cell with the highest ranking criterion value. If the cell frequency of the cell with the highest ranking criterion value is less than or equal to the preset frequency, the target cell is the cell with the highest ranking criterion value. If the network device is configured with the preset value and the cell with the highest ranking criterion value is not a cell with a cell frequency less than or equal to the preset frequency, it can be determined that the cell with the highest number of good beams among at least one similar cell is the target cell. If there is more than one cell with the highest number of good beams in the at least one similar cell, the target cell is the cell with the highest ranking criterion value among the cells with the highest number of good beams.

Optionally, in some embodiments, the network device may send an indication information to the terminal, where the indication information is used to indicate whether a cell that the terminal meets the preset condition participates in a good number of beams.

Optionally, in other embodiments, the terminal may also determine whether a cell that satisfies a preset condition participates in a comparison of the number of good beams. The comparison of the number of good beams refers to selecting the target cell by comparing the number of good beams of each cell in at least one similar cell.

Optionally, in some embodiments, if a cell satisfying the preset condition participates in a comparison of the number of good beams, the terminal may determine the target cell by using the method shown in FIG. 4. If the cell satisfying the preset condition does not participate in the comparison of the number of good beams, the terminal may determine the target cell by using the method shown in FIG. 1.

Optionally, in some embodiments, if a cell satisfying the preset condition participates in a comparison of the number of good beams, the terminal may determine the target cell by using the method shown in FIG. 2. If the cell satisfying the preset condition does not participate in the comparison of the number of good beams, the terminal may determine the target cell by using the method shown in FIG. 1.

Optionally, in some embodiments, the cell satisfying the preset condition is a cell whose cell frequency is one frequency in a frequency set, where the frequency set includes at least one frequency. Optionally, in some embodiments, the frequency set may be sent by the network device to the terminal. The indication information used to indicate whether the cell that the terminal meets the preset condition participates in the number of beams and the frequency set may be sent to the terminal at the same time, or may be sent to the terminal separately.

Optionally, in other embodiments, the cell satisfying the preset condition is a cell whose cell frequency is within a frequency band range in a frequency band set. Optionally, in some embodiments, the frequency band set may be sent by the network device to the terminal. The indication information used to indicate whether the cell that the terminal satisfies the preset condition participates in the number of beams may be sent to the terminal at the same time, or may be sent to the terminal separately.

Optionally, in other embodiments, the cell satisfying the preset condition is a cell whose cell frequency is lower than or equal to the preset frequency. Optionally, in some embodiments, the preset frequency may be sent by the network device to the terminal. The indication information used to indicate whether the cell that the terminal satisfies the preset condition participates in the number of beams may be sent to the terminal simultaneously with the preset frequency, or may be sent to the terminal separately.

Optionally, in some embodiments, the terminal determines that a cell satisfying the preset condition does not participate in the comparison of the number of good beams. In this case, if a ranking criterion value of a cell satisfying the preset condition is the highest, the terminal may determine that the cell is the target cell. In other words, if the terminal device determines that the cell with the highest ranking criterion value is a cell satisfying the preset condition, the cell is the target cell.

Optionally, in some embodiments, the terminal determines that a cell satisfying the preset condition participates in a comparison of the number of good beams. In this case, if at least one nearby cell includes a cell that satisfies the preset condition, when comparing the number of good beams, it can be considered that the number of good beams when comparing the number of good beams in a cell that meets the preset condition is The maximum value of the number of good beams in the at least one similar cell or a preset value.

For example, it is assumed that among cell 1, cell 2, cell 3, cell 4, and cell 5, cells 1 to 3 are cells that satisfy the preset condition. Assume that the ranking criterion values of cells 1 to 5 are -61 dBm, -63.5 dBm, -59 dBm, -64 dBm, and -60 dBm, respectively. The actual number of good beams of cells 1 to 5 are 1, 1, 1, 4, and 5, respectively. Assuming that the preset value used to determine a similar cell is 3 dBm, a cell with a ranking criterion value greater than -62 dBm is a similar cell. That is, cell 1, cell 3, and cell 5 are similar cells. Next, compare the number of beams. Because cell 1 and cell 3 are cells satisfying the preset condition. Therefore, when comparing the number of good beams, it can be considered that the number of good beams in the two cells is the maximum number of good beams in the five cells, that is, five. In this case, cell 1, cell 3, and cell 5 all have the largest number of good beams. Because there is more than one cell with the largest number of good beams, it can be determined that the highest ranking criterion value is the target cell. In this case, the cell 3 may be determined as the target cell.

For example, it is assumed that among cell 1, cell 2, cell 3, cell 4, and cell 5, cells 1 to 3 are cells that satisfy the preset condition. Assume that the ranking criterion values of cells 1 to 5 are -61 dBm, -63.5 dBm, -59 dBm, -64 dBm, and -60 dBm, respectively. The actual number of good beams of cells 1 to 5 are 1, 1, 1, 4, and 5, respectively. Assuming that the preset value used to determine a similar cell is 3 dBm, a cell with a ranking criterion value greater than -62 dBm is a similar cell. That is, cell 1, cell 3, and cell 5 are similar cells. Next, compare the number of beams. Because cell 1 and cell 3 are cells satisfying the preset condition. Therefore, when comparing the number of good beams, it can be considered that the number of good beams of the two cells is a preset value. Assume that the preset value is 7. In this case, both cell 1 and cell 3 have the largest number of good beams. Because there is more than one cell with the largest number of good beams, it can be determined that the highest ranking criterion value is the target cell. In this case, the cell 3 may be determined as the target cell.

Optionally, in some embodiments, the network device may configure the terminal with a good number of beams. When the terminal compares the number of good beams, it can be considered that the number of good beams of a cell satisfying a preset condition is the number of good beams configured by the network device. Specifically, if a nearby cell includes a cell that satisfies the preset condition, when the terminal performs a comparison of the number of good beams, the terminal may consider that the number of good beams of the cell that satisfies the preset condition is the network. Number of good beams configured by the device.

Optionally, in some embodiments, if the network device does not configure a good number of beams for the terminal, the terminal may consider that the number of good beams of a cell that satisfies a preset condition is used for Determine the upper limit of the number of beams above the threshold for cell quality.

Optionally, in other embodiments, if the network device does not configure a good number of beams for the terminal, the terminal may consider that the number of good beams of the cell that meets the preset condition is Actual value of the number of good beams of the cell that meets the preset condition.

Optionally, in some embodiments, the network device may configure a terminal with a good beam number threshold. When the terminal compares the number of good beams, it can be considered that if the number of good beams of a cell satisfying a preset condition is greater than or equal to the threshold of the number of good beams, the number of good beams in the cell is the maximum number of good beams in the similar cell. .

For example, it is assumed that among cell 1, cell 2, cell 3, cell 4, and cell 5, cells 1 to 3 are cells that satisfy the preset condition. Assume that the ranking criterion values of cells 1 to 5 are -61 dBm, -63.5 dBm, -59 dBm, -64 dBm, and -60 dBm, respectively. The actual number of good beams in cells 1 to 5 are 2, 1, 3, 4, and 5. Assuming that the preset value used to determine a similar cell is 3 dBm, a cell with a ranking criterion value greater than -62 dBm is a similar cell. That is, cell 1, cell 3, and cell 5 are similar cells. Next, compare the number of beams. Assume that the threshold of the number of good beams is 2. Because cell 1 and cell 3 are cells satisfying the preset condition and the number of good beams of cell 1 and cell 3 is greater than or equal to two. Therefore, when comparing the number of good beams, it can be considered that the number of good beams in the two cells is the maximum number of good beams in the five cells, that is, five. In this case, cell 1, cell 3, and cell 5 all have the largest number of good beams. Because there is more than one cell with the largest number of good beams, it can be determined that the highest ranking criterion value is the target cell. In this case, the cell 3 may be determined as the target cell.

Optionally, in some embodiments, if the network device does not configure the terminal with the good beam number threshold, the good beam number threshold may be a default value, for example, the default value may be 1.

Optionally, in other embodiments, if the network device does not configure the terminal with the good beam number threshold, the good beam number threshold may be an upper limit of the number of beams higher than a threshold for determining cell quality.
