A cell reselection method and communication device
[0001] This application claims priority to Chinese Patent Application No. 202410581679.1, filed with the State Intellectual Property Office of China on May 10, 2024, entitled "A Cell Reselection Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of communication technology, and in particular to a cell reselection method and communication device. Background Technology
[0003] Cell reselection refers to the process by which a terminal monitors the signal quality of neighboring cells and the current serving cell to select the best cell to provide a service signal.
[0004] To conserve network energy, some cells support network energy saving (NES) capabilities. When the coverage area of an NES-enabled cell (or NES cell) is within the coverage area of a regular cell, the UE, after camping on the regular cell, may not be able to perform cell reselection based on cell reselection-related parameters (such as parameters related to determining whether to trigger start measurement, cell reselection evaluation parameters, etc.) to access the NES cell. Summary of the Invention
[0005] This application provides a cell reselection method and communication device for enabling terminals supporting NES capabilities to access NES cells.
[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:
[0007] In the first aspect, a cell reselection method is provided, which is applied to a first type of terminal that supports NES capability. The method may include: obtaining a first parameter;
[0008] The first parameter is used for cell reselection in NES cells, and correspondingly, the first parameter may include cell reselection parameters for NES cells.
[0009] Alternatively, the first parameter is used for cell reselection by the first type of terminal. Correspondingly, the first parameter is configured by the NES terminal, and the first parameter may include cell reselection parameters for the NES terminal.
[0010] Then, based on the first parameter mentioned above, cell reselection is performed.
[0011] In this application, since the first parameter can be used for cell reselection in NES cells and for cell reselection by the first type of terminal, when the first type of terminal uses the first parameter for cell reselection, the probability of reselecting to an NES cell can be increased, so that the first type of terminal can perform cell reselection even if it is not at the edge of the serving cell.
[0012] In one possible design, the first type of terminal can also acquire a second parameter. This second parameter is used by the second type of terminal to perform cell reselection. Accordingly, the second parameter may include cell reselection parameters for NES cells and / or cell reselection parameters for non-NES cells. The second type of terminal does not support NES capability.
[0013] Alternatively, the second parameter is used by the first type of terminal to perform non-NES cell reselection. Accordingly, the second parameter includes cell reselection parameters for non-NES cells.
[0014] Subsequently, the first type of terminal performs cell reselection based on the second parameter mentioned above, so that the first type of terminal can reselect a cell, such as a non-NES cell.
[0015] In this application, the first type of terminal can use the second parameter to perform cell reselection for non-NES cells.
[0016] In one possible design approach, cell reselection may include initiating measurements, specifically in the case of intra-frequency cell reselection; or...
[0017] When cell reselection is performed for cells at different frequencies / system frequencies, measurements are initiated.
[0018] Based on this, the first type of terminal can directly start the measurement without having to determine whether to start the measurement according to condition 1, thus relaxing the start measurement and increasing the possibility of reselecting to the NES cell.
[0019] Optionally, if the cell reselection is a same-frequency cell reselection and the same-frequency cell is an NES cell, the measurement is initiated; or...
[0020] Measurements are initiated when the cell reselection is performed for a different frequency or system, and the cell at that frequency or system is an NES cell. This avoids frequent measurement initiation by the first type of terminal.

[0029] If the first signal amplitude of the serving cell is greater than the first signal amplitude threshold and the first signal strength of the serving cell is greater than the first signal strength threshold, the first type of terminal will not start the same-frequency measurement or the inter-frequency / inter-system frequency measurement.
[0030] When the amplitude of the first signal is less than or equal to the first signal amplitude threshold and the strength of the first signal is less than or equal to the first signal strength threshold, the first type of terminal initiates same-frequency measurement or initiates different-frequency / different-system frequency measurement.
[0031] or,
[0032] If the first signal amplitude is greater than the calculation result between the second signal amplitude threshold and the first bias value corresponding to the signal amplitude, and the first signal strength is greater than the calculation result between the second signal strength threshold and the first bias value corresponding to the signal strength, the first type of terminal will not start the same-frequency measurement or the inter-frequency / inter-system frequency measurement.
[0033] or,
[0034] If the first signal amplitude is greater than the calculation result between the third signal amplitude threshold and the first bias value corresponding to the signal amplitude, and the first signal strength is greater than the calculation result between the third signal strength threshold and the first bias value corresponding to the signal strength, the first type of terminal will not start same-frequency measurement or inter-frequency / inter-system frequency measurement.

[0045] or,

The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.
[0114] To facilitate understanding of the technical solutions of the embodiments of this application, a brief introduction to the relevant technologies of this application is given below.
[0115] System Information Block (SIB): This acts as a link between terminals and network devices. The transmission of SIBs ensures the completion of wireless communication between them. SIB broadcasts provide terminals with access layer and non-access layer information, assisting them in performing various operations within the access network.
[0116] There are various types of SIBs, such as SIB1, SIB2, SIB3, and SIB4. However, there are many types of SIBs, not limited to the four examples mentioned above.
[0117] A cell is a term used by higher layers to describe a resource management, mobility management, or service unit. The coverage area of each base station can be divided into one or more cells, and each cell can correspond to a frequency range. Each cell can operate within its corresponding frequency range. A frequency range can be a single frequency point or a frequency band. This application does not impose any limitations on this.
[0118] Cell reselection refers to the process by which a terminal, in its radio resource control (RRC) idle or inactive state, selects the cell with the best signal quality to provide a service signal by detecting the signal quality of neighboring cells and the serving cell. For example, as shown in Figure 1, the cell reselection process may include:
[0119] S101. The terminal starts the measurement according to condition 1.
[0120] The aforementioned "initiation measurement" can refer to initiating neighbor cell measurements, such as initiating intra-frequency cell measurements (or intra-frequency measurements) or inter-frequency / inter-system frequency cell measurements (or inter-frequency / inter-system frequency measurements). Intra-frequency cells are neighbor cells that share the same frequency as the terminal's currently serving cell. Inter-frequency / inter-system frequency cells are neighbor cells that share a different frequency than the terminal's currently serving cell.
[0121] Optionally, the frequency points of the aforementioned inter-frequency / inter-system frequencies have a higher priority than the frequency points of the terminal's current serving cell, which are neighboring cells with higher priority (referred to as high-priority inter-frequency / inter-system frequencies). Accordingly, the aforementioned inter-frequency / inter-system frequency measurements include high-priority inter-frequency / inter-system frequency measurements.
[0122] And / or, the aforementioned inter-frequency / inter-system frequency cells include frequency points with a priority lower than or equal to that of the terminal's current serving cell (referred to as low-priority or equal-priority inter-frequency / inter-system frequencies). Accordingly, the aforementioned inter-frequency / inter-system frequency measurements include low-priority or equal-priority inter-frequency / inter-system frequency measurements.
[0123] For example, condition 1 above includes:
[0124] 1) For co-frequency measurements, when the neighboring cells of the terminal's current serving cell include co-frequency cells, if the serving cell satisfies Srxlev>S IntraSearchP And Squal>S IntraSearchQ Then the terminal will not initiate co-frequency measurement. If the serving cell's Srxlev ≤ S IntraSearchP Or Squal≤S IntraSearchQ Then the terminal can initiate same-frequency measurement.
[0125] Here, Srxlev represents the cell selection reception level value, which is also the signal amplitude. Srxlev is related to the reference signal reception power (RSRP).
[0126] The above S IntraSearchpThis represents the threshold for initiating same-frequency measurement corresponding to Srxlev, which is the threshold for the signal amplitude to initiate same-frequency measurement.
[0127] The Squal value mentioned above represents the cell selection quality value, which is also the signal strength. Squal is related to the reference signal reception quality (RSRQ).
[0128] The above S IntraSearchQ This represents the threshold for starting same-frequency measurement corresponding to Squal, which is the signal strength threshold for starting same-frequency measurement.
[0129] 2) For inter-frequency / inter-system frequency measurement, if the neighboring cell includes high-priority inter-frequency / inter-system frequencies, the terminal can initiate high-priority inter-frequency / inter-system frequency measurement.
[0130] If neighboring cells include frequencies from different frequencies / systems with lower or equal priority, then the serving cell satisfies Srxlev>S. nonIntraSearchP And Squal>S nonIntraSearchQ In this case, the terminal will not initiate low-priority or equal-priority inter-frequency / inter-system frequency measurements. And in the serving cell, Srxlev≤S nonIntraSearchP Or Squal≤S nonIntraSearchQ In such cases, the terminal can initiate low-priority or equal-priority inter-frequency / inter-system frequency measurements.
[0131] The above S nonIntraSearchP This represents the threshold for starting inter-frequency / inter-system frequency measurement corresponding to Srxlev, which is also the threshold for the signal amplitude to start inter-frequency / inter-system measurement.
[0132] S nonIntraSearchQ This represents the threshold for starting inter-frequency / inter-system frequency measurement corresponding to Squal, which is the signal strength threshold for starting inter-frequency / inter-system measurement.
[0133] In some embodiments, Srxlev can be calculated using Equation 1. Specifically, Equation 1 can be Srxlev = Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp .
[0134] Among them, the above Q rxlevmeas Q represents the signal reception level (or received signal power) of the tested cell, that is, the strength of the received signal measured by the terminal. Additionally, Q... rxlevmeas It can also be understood as the reference signal received power measured by the terminal.
[0135] The above Q rxlevmin This represents the minimum signal reception level of the measured cell, i.e., the minimum required signal reception level in the measured cell.
[0136] The above Q rxlevminoffset It is an offset value, representing the offset of the cell signal reception level when the terminal switches from a virtual public land mobile network (VPLMN) to a higher-priority public land mobile network (PLMN). In other words, it represents the offset given to Q when the terminal is camped on the VPLMN and periodically searches for a higher-priority PLMN. rxlevmin Added bias value Q rxlevminoffset .
[0137] The above Qoffset temp This represents a temporary bias value, which is the bias value used to select the cell signal reception level of the cell under test within a duration of 1, in the event that the terminal has failed to establish a connection with the cell under test.
[0138] The above P compensation This refers to power, specifically the power compensation value, which represents a parameter related to the terminal's uplink power compensation. For example, for low-frequency bands (FR1), such as the Sub-6GHz band, if the terminal supports the maximum transmit power in the non-standalone (NS) mode of 5G NR (5th-generation mobile communication technology new radio), then P... compensation It can be calculated using Formula 2. Otherwise, P compensation It can be calculated using Formula 3.
[0139] Specifically, Formula 2 above can be P compensation =max(P EMAX1 -P PowerClass ,0)-(min(P EMAX2 P PowerClass )-min(P EMAX1 P PowerClass ))(dB).
[0140] Formula 3 above can be P compensation =max(P EMAX1 -P PowerClass ,0)dB.
[0141] Among them, the above PEMAX1 and P EMAX2 This is the maximum transmit power used by the terminal device during uplink transmission. The aforementioned P PowerClass This refers to the terminal's maximum carrier frequency transmit power.
[0142] For high-frequency bands (FR2), such as millimeter-wave bands, the above P compensation It can be 0.
[0143] The above section introduced content related to Srxlev; the following section will continue with content related to Squal.
[0144] For example, the above Squal can be calculated using Formula 4. Formula 4 can be: Squal = Q qualmeas -(Q qualmin +Q qualminoffset -Qoffset temp .
[0145] Among them, the above Q qualmeas This indicates the signal reception quality value of the tested cell, which in turn indicates the quality of the received signal measured by the terminal.
[0146] The above Q qualmin This represents the minimum value of the cell signal reception quality, that is, the minimum required cell signal reception quality value in the tested cell.
[0147] The above Q qualminoffset It is an offset value, which represents the offset of the cell signal reception quality value when the terminal switches from VPLMN to a higher priority PLMN. In other words, it is the offset value given to Q when the terminal switches from VPLMN to a higher priority PLMN. qualmin Added bias value Q qualminoffset .
[0148] Qoffset temp This represents a temporary bias value, which is used to select the cell signal reception quality value of the cell to be measured within a duration of 2, in the event that the terminal has failed to establish a connection with the cell under test.
[0149] It is understandable that the above parameters, such as Q, rxlevmin Q rxlevminoffset P compensation Q offsettemp Q qualmin Q qualminoffset And Q offsettemp The parameters configured by network devices for terminals can also be called cell selection parameters. The above Q... rxlevmeas and Q qualmeasThese are the parameters measured by the terminal. Both the cell selection parameters and the terminal measurement parameters are related to triggering the terminal to start the measurement. Whether the terminal can camp on the cell being measured needs to be determined based on the terminal measurement parameters and the cell selection parameters.
[0150] S102. The terminal performs a cell reselection assessment based on the cell reselection criteria to obtain candidate cells for cell reselection.
[0151] S102 can also be described as selecting a cell according to the cell reselection criteria.
[0152] S103, The terminal attempts to access the candidate cell.
[0153] The aforementioned cell reselection assessment refers to the terminal determining whether neighboring cells meet the cell reselection criteria. The terminal (e.g., UE) can use neighboring cells that meet the criteria as candidate cells. Then, the terminal can perform a cell search on the candidate cells and receive system messages from those candidate cells to determine whether the candidate cell can be used for normal camping, i.e., the terminal performs cell reselection. For example, based on the system message from the candidate cell, it can determine whether access is restricted (e.g., whether the information carried in the candidate cell's system message is "barred" or "reserved"). If access is possible in the candidate cell, the terminal can camp on that candidate cell, thereby achieving cell reselection.
[0154] In some embodiments, the above cell reselection criteria may include:
[0155] 1) For neighboring cells of the current serving cell, including high-priority inter-frequency / inter-system frequency cells, when threshServingLowQ is configured, if the terminal's dwell time in the current serving cell is greater than time 1, and the Squal of the high-priority inter-frequency / inter-system frequency cell is greater than the high-intensity reselection threshold (Thresh... X,HighQ If the duration of a cell is greater than the time interval 1, then the terminal can reselect the high-priority inter-frequency / inter-system frequency cell. In other words, the high-priority inter-frequency / inter-system frequency cell can be used as a candidate cell.
[0156] If the terminal's dwell time in the current serving cell is less than or equal to time 1, or if the Squal of the high-priority inter-frequency / inter-system frequency cell is greater than Thresh. X,HighQ If the duration of the interval is less than or equal to 1, the high-priority inter-frequency / inter-system frequency cell will not be considered as a candidate cell.
[0157] When threshServingLowQ is not configured, if the terminal stays in the current serving cell for more than time 2, and the Srxlev of the high-priority inter-frequency / inter-system frequency cell is greater than the reselection high amplitude threshold (Thresh...), then... X,HighP If the duration of a high-priority inter-frequency / inter-system frequency cell is greater than the time interval 2, then the high-priority inter-frequency / inter-system frequency cell can be used as a candidate cell.
[0158] If the terminal's dwell time in the current serving cell is less than or equal to time 2, or if the Srxlev of the higher-priority inter-frequency / inter-system frequency cell is greater than Thresh. X,HighP If the duration of the interval is less than or equal to 2, the high-priority inter-frequency / inter-system frequency cell will not be considered as a candidate cell.
[0159] 2) For neighboring cells of the current serving cell, including low-priority inter-frequency / inter-system frequency cells, when threshServingLowQ is configured, if the terminal stays in the current serving cell for more than time 3, and the Squal of the low-priority inter-frequency / inter-system frequency cell is greater than the reselection low-strength threshold (Thresh... X,LowQ If the Squal of the current serving cell is less than the ThreshServing (LowQ) threshold for a duration greater than the time interval 3, the low-priority inter-frequency / inter-system frequency cell can be used as a candidate cell.
[0160] If the terminal spends less than or equal to 3 hours in the current serving cell, or if the Squal of the low-priority inter-frequency / inter-system frequency cell is greater than Thresh. X,LowQ If the Squal of the current serving cell is less than ThreshServing and the duration of LowQ is less than or equal to the time interval 3, the low-priority inter-frequency / inter-system frequency cell will not be considered as a candidate cell.
[0161] When threshServingLowQ is not configured, if the terminal stays in the current serving cell for more than 4 hours, and the Srxlev of the low-priority inter-frequency / inter-system frequency cell is greater than the reselection low amplitude threshold (Thresh...), then... X,LowP If the duration of the current serving cell’s Srxlev being less than the ThreshServing (LowP) threshold is greater than the time interval 4, then this low-priority inter-frequency / inter-system frequency cell can be used as a candidate cell.
[0162] If the terminal spends less than or equal to 4 hours in the current serving cell, or if the Srxlev of the low-priority inter-frequency / inter-system frequency cell is greater than Thresh. X,LowP If the Srxlev of the current serving cell is less than ThreshServing, and the duration of LowP is less than or equal to the time interval 4, the low-priority inter-frequency / inter-system frequency cell will not be considered as a candidate cell.
[0163] The above-mentioned threshServingLowQ defines the measurement threshold value of the serving cell when the terminal device reselects a cell with a lower priority.
[0164] For neighboring cells of the current serving cell, including cells of equal priority but different frequencies / system frequencies, or cells of the same frequency, the cell reselection criteria mentioned above may include the R criterion. Taking the inclusion of cells of the same frequency as an example, the R criterion may be: if the terminal stays in the current serving cell for more than 5 hours, and the duration of the grade determination criterion (Rn) of the cells of the same frequency being greater than the grade determination criterion (Rs) of the current serving cell is greater than or equal to the time interval 5, then the cells of the same frequency can be considered as candidate cells.
[0165] If the terminal stays in the current serving cell for a period of time less than or equal to 5, and the duration of Rn being greater than Rs is less than the time interval 5, then the co-frequency cell is not a candidate cell.
[0166] The aforementioned Rs can be calculated using Formula 5, which can be Rs = Q. meas,s +Q hyst -Qoffset temp The above Rn can be calculated using Formula Six, which can be R... n =Q meas,n -Qoffset-Qoffset temp .
[0167] The parameters involved in Formulas 5 and 6 above can be shown in Table 1.
[0168] Table 1
[0169] The times 1 through 5 mentioned above can be the same, such as all being 1 second, or they can be different, meaning that some or all of the times in times 1 through 5 are different. Similarly, the time intervals 1 through 5 mentioned above can also be the same, and all can be selected using Treselection. RAT This means that time intervals 1 through 5 can also be different.
[0170] It should be understood that when neighboring cells include inter-frequency / inter-system frequency cells of equal priority, simply replace the description of the same-frequency cells in the R criterion introduced above as inter-frequency / inter-system frequency cells of equal priority.
[0171] In some embodiments, the terminal can also, according to Q meas,s and Q meas,n Neighboring cells are sorted so that terminals can use the sorted neighboring cells for cell reselection.
[0172] Additionally, if the serving cell does not have the optimal cell indication information (rangeToBestCell) configured, the terminal can reselect the cell with the highest R value. If rangeToBestCell is configured, the terminal can reselect the cell with an R value within a certain range.
[0173] [R best -rangeToBestCell,R best Within the range and with beam quality higher than
[0174] The cell with the most beams in absThreshSS-BlocksConsolidation. Here, absThreshSS-BlocksConsolidation is the SSB beam threshold.
[0175] Rbest can also be represented as Rmax, which represents the maximum R value determined from the serving cell and neighboring cells (such as cells that the terminal can measure).
[0176] It should be noted that the cell reselection parameters introduced above can be understood as traditional cell reselection parameters.
[0177] The cells described above can include ordinary cells (or traditional cells) and NES cells. Ordinary cells need to periodically send broadcast system information block (SIB) messages, such as SIB1 messages. NES cells do not need to periodically broadcast SIB1 messages, thus saving network energy compared to ordinary cells.
[0178] When a terminal supporting NES capability (also known as an NES terminal) needs to camp on an NES cell, it can send a wake-up signal (WUS) request to the NES cell. This WUS request requests the NES cell to broadcast an SIB1 message. Upon receiving the WUS request, the NES cell broadcasts the SIB1 message. NES terminals can send WUS requests, while legacy cells, also known as ordinary cells, cannot.
[0179] Specifically, as shown in Figure 2, step 1 involves cell A sending WUS configuration information to the NES UE. Cell A is the NES UE's current serving cell (or camped cell). Afterwards, the NES UE receives the WUS configuration information and executes step 2, sending a WUS request to the NES cell.
[0180] Afterwards, the NES cell receives the WUS request and can execute step 3, broadcasting the SIB1 message so that the NES UE can use the SIB1 message to access the NES cell and achieve cell reselection.
[0181] However, when the coverage area of the aforementioned NES cell is within the coverage area of cell A, cell A typically considers reselecting to other cells at the edge of cell A when configuring cell reselection parameters (such as the parameters related to initiating measurement and those related to performing cell reselection evaluation). Therefore, if the coverage area of the NES cell does not include the edge of cell A, when the terminal is located within the NES cell but not at the edge of cell A, the terminal cannot perform reselection based on the cell reselection parameters. Similarly, when the terminal is at the edge of cell A but not within the NES cell, the terminal still cannot reselect to the NES cell based on the cell reselection parameters. The parameters related to performing cell reselection evaluation can be further described as parameters related to cell selection or parameters related to cell reselection execution.
[0182] In simple terms, when the terminal is in a location where cell reselection is possible in cell A, but this location does not belong to an NES cell,
[0183] If the NES terminal is based on the conventional cell reselection parameters, that is, the NES terminal shares a set of cell reselection parameters with the traditional terminal, the NES terminal will not be able to reselect to the NES cell.
[0184] For example, as shown in Figure 3(a), terminal A is located at the edge of cell A and performs cell reselection. Terminal B is not located at the edge of cell A and does not perform cell reselection. Later, when terminal B moves to the edge of cell A, terminal B can retransmit, but since terminal B's current location does not belong to an NES cell, terminal B cannot reselect to an NES cell (as shown in Figure 3(b)). In Figure 3(a) or (b), terminal B can be an NES terminal.
[0185] Therefore, to address the aforementioned issues, this application sets up a cell reselection process or parameters suitable for NES terminals to relax cell reselection. Traditional terminals can still use traditional cell reselection parameters, thus enabling NES terminals to reselect to NES cells even if they are not located at the edge of their current serving cell, provided the NES cell's coverage area is within the NES terminal's current serving cell. Furthermore, traditional terminals can still use traditional cell reselection parameters, preventing them from reselecting to NES cells.
[0186] The aforementioned NES terminals can also be referred to as Type 1 terminals. Type 1 terminals support the transmission of SIB1 requests, or the transmission of SSB requests, or the adaptive random access procedure. Traditional terminals can also be referred to as Type 2 terminals, ordinary terminals, or non-NES terminals, meaning they do not support SIB1 requests, or the transmission of SSB requests, or the adaptive random access procedure. An NES cell refers to a cell that transmits SIB1 requests based on terminal SIB1 requests, or transmits SSB requests based on terminal SSB requests, or a cell that supports configuring adaptive random access resources.
[0187] The following section, using the touch method flowchart shown in Figure 4 as an example, will introduce relevant content regarding cell reselection parameters suitable for NES terminals. As shown in Figure 4, the flowchart may include:
[0188] S201, NES terminal obtains first parameter.
[0189] S202 and NES terminals perform cell reselection based on the first parameter.
[0190] The first parameter mentioned above can be used for cell reselection in NES cells. The first parameter can include cell reselection parameters for NES cells, enabling first-type terminals to use the first parameter to reselect to NES cells, while traditional terminals cannot use the first parameter, thereby preventing traditional terminals from reselecting to NES cells.
[0191] or,
[0192] The first parameter can be used by NES terminals for cell reselection. The first parameter is configured for NES terminals and may include cell reselection parameters specific to the NES terminal, enabling the NES terminal to reselect to an NES cell. Optionally, the first parameter may also include cell reselection parameters for NES cells and / or non-NES cells (such as the traditional cell reselection parameters described above), thereby enabling the terminal to reselect to a non-NES cell.
[0193] In some embodiments, the NES terminal may also obtain a second parameter. This second parameter can be used by a conventional terminal for cell reselection. The second parameter may include cell reselection parameters for non-NES cells, allowing the conventional terminal to reselect to a non-NES cell. And / or, the second parameter may also include cell reselection parameters for NES cells.
[0194] Alternatively, the second parameter can be used by the NES terminal to perform cell reselection, and the cell reselection is a non-NES cell reselection. That is, the second parameter is used by the NES terminal to perform cell reselection of a non-NES cell, and the second parameter may include cell reselection parameters for non-NES cells.
[0195] Afterwards, the NES terminal can perform cell reselection based on the second parameter, enabling the NES terminal to reselect to a non-NES cell.
[0196] It should be noted that the aforementioned first parameter may also be referred to as the first configuration parameter, first configuration information, first information, etc. This application does not restrict the name of the first parameter, and similarly, this application does not restrict the name of the second parameter.
[0197] In some embodiments, the first parameter and the second parameter can be configured in the first signaling, which can be SIB2 / SIB3 / SIB4 / SIB5. In this case, the first parameter can be used by a first type of terminal to perform cell reselection, and the first parameter includes parameters for cell reselection by the first type of terminal. The second parameter can be used by a second type of terminal and / or a first type of terminal to perform cell reselection, and the second parameter includes parameters for cell reselection by the second type of terminal and / or a first type of terminal. When the first parameter only includes cell reselection parameters for NES cells, the first type of terminal obtains cell reselection parameters for non-NES cells through the second parameter. When the first parameter includes cell reselection parameters for both NES and non-NES cells, and the second parameter includes cell reselection parameters for non-NES cells, the first type of terminal uses the cell reselection parameters for non-NES cells in the first parameter.
[0198] In some embodiments, the first parameter and the second parameter are configured in different signaling messages. For example, the second parameter may be in the first signaling message and the first parameter in the second signaling message, which may be an SIBx. In this case, the first type of terminal can perform cell reselection based on the first parameter and the second parameter. The first parameter includes specific cell reselection parameters, while other parameters may be provided by the second parameter. For example, the first parameter may configure parameters related to initiating measurement, while parameters related to performing cell reselection evaluation may be configured by the second parameter. As another example, the first parameter may configure parameters related to cell selection, while parameters related to initiating measurement may be configured by the second parameter.
[0199] In some embodiments, the first parameter and / or the second parameter include only cell-related parameters, and the third parameter includes frequency-related parameters. The third parameter can be used for both the first type of terminal and the second type of terminal.
[0200] In some embodiments, the first parameter includes cell and frequency-related parameters. The cell-related parameters include Qoffset. s,n Q qualminoffsetcell Q rxlevminoffsetcell And one or more of QrxlevminoffsetcellSUL.
[0201] Among them, Qoffset s,n This indicates the offset between two cells during cell reselection.
[0202] In some embodiments, the first parameter may include parameters related to triggering the start measurement and / or parameters related to cell reselection execution. For example, parameters related to triggering the start measurement may include one or more of the following: threshold 1, threshold 2, threshold 3, offset value 1, inter-frequency / inter-system frequency priority 1, inter-frequency / inter-system frequency priority 2, inter-frequency / inter-system frequency priority 3, offset value 2, threshold 4, threshold 5, threshold 6, offset value 3, neighboring cell frequency 1, neighboring cell frequency 2, neighboring cell frequency 3, offset value 4, parameter 1, parameter 2, parameter 3, and offset value 5. Parameters related to cell reselection execution may include one or more of the following: time 5A, time 5B, time 5C, offset value 6, time interval 5A, time interval 5B, time interval 5C, offset value 7, parameter 4, parameter 5, parameter 6, offset value 8, parameter 7, parameter 8, parameter 9, offset value 9, time 1A, time 1B, time 1C, and offset value 10. The meanings of the parameters included in the first parameter can be found in the relevant content below. The parameters that the first parameter may include will be described in detail below.
[0203] In one possible implementation, the first parameter may include parameters related to the initiation of measurements configured in the serving cell.
[0204] 1) For the serving cell of the terminal, neighboring cells include co-frequency cells. Based on the above, if the serving cell satisfies Srxlev>S... IntraSearchP And Squal>S IntraSearchQ Then the terminal will not initiate co-frequency measurement. If the serving cell's Srxlev ≤ S IntraSearchP Or Squal≤S IntraSearchQ Then the terminal can initiate same-frequency measurement. Therefore, by increasing S... IntraSearchP and / or S IntraSearchQThis increases the likelihood that the S-value of the serving cell is less than the corresponding threshold, thereby relaxing co-frequency measurement so that the first type of terminal can perform co-frequency measurement as soon as possible to reselect to the NES cell.
[0205] Accordingly, the first parameter mentioned above may include threshold 1, which is used to trigger the initiation of co-frequency measurement during cell reselection. Threshold 1 may include a signal amplitude threshold 1 for initiating co-frequency measurement, and / or a signal strength threshold 1 for initiating co-frequency measurement.
[0206] And / or, the first parameter includes threshold 2 and offset value 1, which are used to trigger the initiation of measurement in a co-frequency cell during cell reselection. Threshold 2 may include a signal amplitude threshold 2 for initiating co-frequency measurement, and / or a signal strength threshold 2 for initiating co-frequency measurement; offset value 1 may include an offset value 1 corresponding to the signal amplitude and an offset value 1 corresponding to the signal strength.
[0207] And / or, the first parameter includes an offset value of 1. The NES terminal can acquire a threshold of 3, which, along with the offset value of 1, is used to trigger co-frequency cell initiation measurement during cell reselection.
[0208] Threshold 1 and threshold 2 can be the same (i.e., threshold 2 is threshold 1). Threshold 1 and threshold 2 can also be different. On one hand, the difference in this application can be a difference in the value taken. Threshold 1 and threshold 2 are the same parameter, but the parameter values are different. On the other hand, the difference in this application can refer to a difference in the parameter itself, which can be simply understood as a different parameter identifier. For example, the signal amplitude threshold 2 mentioned above can be S in the traditional cell reselection parameter described above. IntraSearchP The signal amplitude threshold 1 can be S IntraSearchPfornes S IntraSearchP and S IntraSearchPfornes These are not the same parameter. For example, the signal strength threshold 2 is the same as the S value in traditional cell reselection parameters. IntraSearchQ The signal strength threshold 1 is S IntraSearchQfornes S IntraSearchP and S IntraSearchQfornes Not the same parameter.
[0209] Optionally, bias value 1 is used to increase threshold 2, and the calculated result between bias value 1 and threshold 2 is greater than threshold 2.
[0210] Optionally, the threshold 3 mentioned above can be provided by the second parameter. That is, the second parameter mentioned above can include the threshold 3, which can be used to trigger the start of co-frequency measurement during cell reselection.
[0211] Wherein, threshold 3 is less than threshold 1, or the calculated result between bias value 1 and threshold 2 is greater than threshold 3. Wherein, threshold 3 can be threshold 2, and threshold 3 is lower than threshold 1, and bias value 1 can be used to increase threshold 3.
[0212] Similarly, threshold 3 may include a signal amplitude threshold 3 for initiating same-frequency measurement, and / or a signal strength threshold 3 for initiating same-frequency measurement.
[0213] Taking the aforementioned threshold 1 as including a signal amplitude threshold 1 and threshold 3 as including a signal amplitude threshold 3 as an example, if the signal amplitude threshold 1 is greater than the signal amplitude threshold 3, the bias value 1 corresponding to the signal amplitude can be used to increase the signal amplitude threshold 3. For example, the calculation result between the bias value 1 corresponding to the signal amplitude and the signal amplitude threshold 3 is greater than the signal amplitude threshold 3. The calculation result described in this embodiment can be a sum, difference, product, or ratio. For example, if the bias value 1 is a positive number, the sum of the bias value 1 and the signal amplitude threshold 3 is greater than the signal amplitude threshold 3. For example, if the bias value 1 corresponding to the signal amplitude is the value 10, and the signal amplitude threshold 3 is the value a, then 10 + a > a. Taking the aforementioned threshold 1 as including a signal strength threshold 1 and threshold 3 as including a signal strength threshold 3 as an example, if the signal strength threshold 1 is greater than the signal strength threshold 3, the bias value 1 can be used to increase the signal strength threshold 3. For example, the calculated result between the bias value 1 corresponding to the signal strength and the signal strength threshold 3 is greater than the signal strength threshold 3. For instance, if the bias value 1 corresponding to the signal strength is a positive number, the sum of the bias value 1 and the signal strength threshold 3 is greater than the signal strength threshold 3. For example, if the bias value 1 corresponding to the signal strength is the value 9 and the signal strength threshold 3 is the value b, then 9 + b > b.
[0214] Taking the above threshold 1, which includes signal amplitude threshold 1 and signal strength threshold 1, and threshold 3, which includes signal amplitude threshold 3 and signal strength threshold 3, as an example, the signal amplitude threshold 1 is greater than the signal amplitude threshold 3, and the signal strength threshold 1 is greater than the signal strength threshold 3.
[0215] Specifically, the bias value 1 corresponding to the signal amplitude is used to increase the signal amplitude threshold 3. The bias value 1 corresponding to the signal strength increases the signal strength threshold 3. For example, the sum of the bias value 1 corresponding to the signal amplitude and the signal amplitude threshold 3 is greater than the signal amplitude threshold 3, and the sum of the bias value 1 corresponding to the signal strength and the signal strength threshold 3 is greater than the signal strength threshold 3. Accordingly, when the serving cell satisfies Srxlev>S IntraSearchP +S offset1 And Squal>
[0216] S IntraSearchQ +S offset2 When the NES terminal is in a certain state, it will not initiate synchronous frequency measurement; otherwise, the NES terminal can initiate synchronous frequency measurement. Wherein, S... offset1This represents the bias value of 1 corresponding to the signal amplitude. offset2 The bias value 1 represents the signal strength.
[0217] Optionally, the bias value 1 corresponding to the signal amplitude and the bias value 1 corresponding to the signal strength can be the same, that is, the bias value 1 corresponding to the signal strength can be the bias value 1 corresponding to the signal amplitude.
[0218] In some embodiments, the threshold 3 may be different from the threshold 2. The threshold 3 is still less than the threshold 1, and the threshold 3 is less than the calculated result between the threshold 2 and the bias value 1.
[0219] The thresholds related to initiating co-frequency measurement (such as threshold 1, threshold 2, and threshold 3 mentioned above) have been introduced above. The following section uses the following as an example: threshold 1 includes signal amplitude threshold 1 and signal strength threshold 1; threshold 2 includes signal amplitude threshold 2 and signal strength threshold 2; threshold 3 includes signal amplitude threshold 3 and signal strength threshold 3; offset value 1 includes offset value 1 corresponding to signal amplitude and offset value 1 corresponding to signal strength; and the above calculation results are and , to introduce the method of the terminal initiating co-frequency measurement using this threshold.
[0220] When the terminal is a Class I terminal, the same-frequency measurement is performed according to the following method:
[0221] When Srxlev is greater than S IntraSearchPfornes And Squal is greater than S IntraSearchQforNES In the case of Srxlev being less than or equal to S, the NES terminal will not initiate co-frequency measurement. IntraSearchPfornes Or Squal community or equal to S IntraSearchQforNES In this case, the NES terminal initiates a synchronous frequency measurement. IntraSearchPfornes Indicates the signal amplitude threshold 1, S IntraSearchQforNES This indicates a signal strength threshold of 1. Additionally, S here... IntraSearchPfornes It can also be done through S IntraSearchP S indicates that IntraSearchPfornes It can also be done through S IntraSearchP This indicates that the NES terminal can still operate according to Srxlev>S IntraSearchP And Squal>S IntraSearchQ Determine whether to initiate frequency measurement, except for S here. IntraSearchP The value is the value of the signal amplitude threshold 1. S IntraSearchQ The value is the value of the signal strength threshold 1.
[0222] or,
[0223] When Srxlev>(S IntraSearchP +S offset1 And Squal>(S IntraSearchQ +Soffset2 In the case of S, the NES terminal does not initiate co-frequency measurement. Otherwise, the NES terminal initiates co-frequency measurement. IntraSearchP Indicates the signal amplitude threshold 2, S offset1 S represents the bias value 1 corresponding to the signal amplitude. IntraSearchP Indicates signal strength threshold 1, S offset2 The bias value 1 represents the signal strength.
[0224] or,
[0225] When Srxlev>(S IntraSearchP +S offset1 And Squal>(S IntraSearchQ +S offset2 In the case of S, the NES terminal does not initiate co-frequency measurement. Otherwise, the NES terminal initiates co-frequency measurement. IntraSearchP This indicates that the above signal amplitude threshold is 3, S offset1 S represents the bias value 1 corresponding to the signal amplitude. IntraSearchP This indicates that the above signal strength threshold 3, S offset2 This represents the bias value 1 corresponding to the signal strength. The signal amplitude threshold 3 can be the signal amplitude threshold for initiating co-frequency measurement as described in section S101 above, which is the signal amplitude threshold for initiating co-frequency measurement in traditional cell reselection parameters. The signal strength threshold 3 can be the signal strength threshold for initiating co-frequency measurement as described in section S101 above, which is the signal strength threshold for initiating co-frequency measurement in traditional cell reselection parameters.
[0226] The first type of terminal obtains whether the co-frequency cell is an NES cell through the first indication information. When the first indication information indicates that the first cell is an NES cell, and the first cell is included in the co-frequency cell, the above method can be executed.
[0227] In one possible design, the above method is used only when the co-frequency cell includes an NES cell; when the co-frequency cell does not include an NES cell, the first type of terminal uses the following method for cell reselection, namely...
[0228] When Srxlev>S IntraSearchP And Squal>S IntraSearchQ In the event of [condition], the NES terminal does not initiate co-frequency measurement. Otherwise, the NES terminal initiates co-frequency measurement. Wherein, S IntraSearchP This indicates that the above signal amplitude threshold is 3, S IntraSearchP This indicates the signal strength threshold of 3 mentioned above.
[0229] Additionally, when the terminal is a type II terminal, the same-frequency measurement should be initiated using the following method:
[0230] When Srxlev>S IntraSearchP And Squal>S IntraSearchQ In the case of [condition], traditional terminals do not initiate same-frequency measurement. Otherwise, traditional terminals initiate same-frequency measurement. Wherein, S IntraSearchP This indicates that the above signal amplitude threshold is 3, S IntraSearchP This indicates the signal strength threshold of 3 mentioned above.
[0231] In this embodiment, the serving cell increases the probability of initiating co-frequency measurement by raising the S-value threshold used to initiate co-frequency measurement, thereby increasing the likelihood of the NES terminal performing cell reselection.
[0232] 2) Regarding the neighboring cells of the serving cell of the terminal, which include inter-frequency / inter-system frequencies, as described above, if the inter-frequency / inter-system frequency includes a high-priority inter-frequency / inter-system frequency, the terminal can initiate high-priority inter-frequency / inter-system frequency measurement. Therefore, the serving cell can relax the measurement of inter-frequency / inter-system frequencies by increasing the priority of the frequency points of the inter-frequency / inter-system frequencies. Accordingly, the first parameter mentioned above can include the priority 1 of the inter-frequency / inter-system frequency. Priority 1 is used to trigger inter-frequency / inter-system frequency measurement during cell reselection. Optionally, the inter-frequency / inter-system frequency can be a low-priority or equal-priority inter-frequency / inter-system frequency.
[0233] And / or, the first parameter mentioned above may include the priority 2 and offset value 2 of the inter-frequency / inter-system frequency. The priority 2 and offset value 2 are used to trigger inter-frequency / inter-system frequency measurement during cell reselection. Optionally, the inter-frequency / inter-system frequency is a low-priority or equal-priority inter-frequency / inter-system frequency.
[0234] And / or, the first parameter mentioned above may include an offset value 2 for the inter-frequency / inter-system frequency. The NES terminal may acquire the priority 3 of the inter-frequency / inter-system frequency, which, along with the offset value 2, is used to trigger inter-frequency / inter-system frequency measurement during cell reselection.
[0235] Among them, priority 2 can be priority 1, or priority 1 and priority 2 are different. For example, priority 2 is the priority of inter-frequency / inter-system frequency in the traditional second type of terminal or traditional cell reselection parameters.
[0236] Optionally, the aforementioned bias value 2 is used to increase priority 2, and the calculation result between bias 2 and priority 2 is greater than priority 2.
[0237] Alternatively, the priority 3 of the aforementioned inter-frequency / inter-system frequency can be provided by a second parameter. That is, the second parameter can include the priority 3 of the inter-frequency / inter-system frequency point. Priority 3 is used to trigger the initiation of inter-frequency / inter-system frequency measurement during cell reselection. Priority 3 is less than priority 1, or priority 3 is less than the calculated result of priority 2 and offset value 2; wherein priority 3 can be priority 2, and priority 3 is lower than priority 1, and offset value 2 is used to increase priority 3. For example, the calculated result between offset value 2 and priority 3 is higher than priority 3.
[0238] For example, the serving cell's frequency is F1, and the inter-frequency / inter-system frequency is F2. F1 has a priority of 2, and F2 has a priority of 0. Here, F2's priority could be 3. When the inter-frequency / inter-system frequency cell includes an NES cell, the NES terminal can calculate the sum of priority 3 (i.e., value 0) and offset value 2 (e.g., value 3) to increase priority 3. Using the increased priority 3, which is greater than F1's priority, the NES terminal can initiate higher-priority inter-frequency / inter-system frequency measurements.
[0239] Furthermore, for the same inter-frequency / inter-system frequency cell, if the inter-frequency / inter-system frequency cell includes an NES cell, the inter-frequency / inter-system frequency cell can have two priorities (one lower priority (e.g., 0) and the other higher priority (e.g., 3)). Priority 3 can be the lower priority, and priority 1 can be the higher priority. Simply put, the lower priority is configured for traditional terminals, and the higher priority is configured for NES terminals.
[0240] It should be noted that if the priority of the inter-frequency / inter-system frequency (such as the priority 3 of the inter-frequency / inter-system frequency mentioned above) is greater than the priority of the frequency point of the serving cell, the NES terminal can directly start the high-priority inter-frequency / inter-system frequency measurement without increasing the priority of the inter-frequency / inter-system frequency.
[0241] The priorities of inter-frequency / inter-system frequencies (such as priority 1, priority 2, and priority 3 mentioned above) related to initiating inter-frequency / inter-system frequency measurements have been introduced above. The following section uses the above calculation results as an example to introduce the method of initiating inter-frequency / inter-system frequency measurements using these priorities.
[0242] When the terminal is a Type 1 terminal, inter-frequency / inter-system frequency measurement is performed according to the following method:
[0243] When the terminal is a Type 1 terminal, the priority for inter-frequency measurement is Priority 1, and the priority for inter-system frequency measurement is Priority 1. When Priority 1 is higher than the priority of the serving cell's frequency point, the NES terminal can initiate high-priority inter-frequency / inter-system frequency measurement. Otherwise, the NES terminal will not initiate high-priority inter-frequency / inter-system frequency measurement.
[0244] or,
[0245] When the terminal is a Class 1 terminal, the priority of inter-frequency communication is (priority 2 + P). offset The priority of different system frequencies is (priority 2 + P). offset ), when (priority 2+P) offset When the frequency point has a higher priority than the serving cell's frequency point, the NES terminal can initiate high-priority inter-frequency / inter-system frequency measurement. Otherwise, the NES terminal will not initiate high-priority inter-frequency / inter-system frequency measurement. offset This indicates a bias value of 2.
[0246] or,
[0247] When the terminal is a Class 1 terminal, the priority of inter-frequency communication is (priority 3 + P). offset The priority of inter-system frequencies is (priority 3 + offset value 2). When (priority 3 + offset value 2) is higher than the priority of the serving cell's frequency point, the NES terminal can initiate high-priority inter-frequency / inter-system frequency measurement. Otherwise, the NES terminal will not initiate high-priority inter-frequency / inter-system frequency measurement. Here, priority 3 can be the inter-frequency / inter-system frequency priority described in S101 above, which is the inter-frequency / inter-system frequency priority in traditional cell reselection parameters.
[0248] In one possible design, the first type of terminal obtains whether the inter-frequency / inter-system frequency is an NES cell through the second indication information. The above method is used only when the inter-frequency / inter-system frequency includes an NES cell; when the inter-frequency / inter-system frequency does not include an NES cell, the first type of terminal uses the following method for cell reselection:
[0249] The priority for inter-frequency measurement is 3, and the priority for inter-system frequency measurement is also 3. When priority 3 is higher than the priority of the serving cell's frequency point, the NES terminal can initiate high-priority inter-frequency / inter-system frequency measurement. Otherwise, the NES terminal will not initiate high-priority inter-frequency / inter-system frequency measurement.
[0250] Additionally, when the terminal is a Type II terminal, inter-frequency / inter-system frequency measurement should be initiated using the following method:
[0251] The priority for inter-frequency measurement is 3, and the priority for inter-system frequency measurement is also 3. When priority 3 is higher than the priority of the serving cell's frequency point, the traditional terminal can initiate high-priority inter-frequency / inter-system frequency measurement. Otherwise, the traditional terminal will not initiate high-priority inter-frequency / inter-system frequency measurement.
[0252] In some embodiments, the priority 1 of the inter-frequency and the priority 1 of the inter-system frequency can be different values. The NES terminal does not initiate high-priority inter-frequency / inter-system frequency measurement, that is, the NES terminal performs measurement according to the low-priority or equal-priority inter-frequency / inter-system frequency measurement initiation conditions.
[0253] In this embodiment, the serving cell increases the priority of inter-frequency / inter-system frequency points by increasing the priority of initiating high-priority inter-frequency / inter-system frequency measurements, thereby increasing the likelihood of the NES terminal performing cell reselection.
[0254] The above section described how to relax the measurement of high-priority inter-frequency / inter-system frequencies when the neighboring cells of the serving cell of a terminal include inter-frequency / inter-system frequencies. In addition, inter-frequency / inter-system frequencies may also include low-priority or equal-priority inter-frequency / inter-system frequencies. The following section will further explain how to relax the measurement of low-priority or equal-priority inter-frequency / inter-system frequencies.
[0255] Based on the above, if the inter-frequency / inter-system frequencies include inter-frequency / inter-system frequencies of lower or equal priority, then in the serving cell, Srxlev > S nonIntraSearchP And Squal>S nonIntraSearchQ In this case, the terminal will not initiate low-priority or equal-priority inter-frequency / inter-system frequency measurements. Therefore, the NES terminal can improve S nonIntraSearchP and / or S nonIntraSearchQ To relax the measurement of low-priority or equal-priority inter-frequency / inter-system frequencies.
[0256] Accordingly, the first parameter mentioned above may include threshold 4, which is used to trigger the initiation of low-priority or equal-priority inter-frequency / inter-system frequency measurements during cell reselection. Threshold 4 may include a signal amplitude threshold 4 for initiating inter-frequency / inter-system measurements, and / or a signal strength threshold 4 for initiating inter-frequency / inter-system measurements.
[0257] And / or, the first parameter includes a threshold 5 and an offset value 3, which are used to trigger the initiation of low-priority or equal-priority inter-frequency / inter-system measurements during cell reselection. The threshold 5 may include a signal amplitude threshold 5 for initiating inter-frequency / inter-system measurements, and / or a signal strength threshold 5 for initiating inter-frequency / inter-system measurements. The offset value 3 includes an offset value 3 corresponding to the signal amplitude and an offset value 3 corresponding to the signal strength.
[0258] And / or, the first parameter includes an offset value of 3. The NES terminal can acquire a threshold of 6, which, along with the offset value of 3, is used to trigger the initiation of low-priority or equal-priority inter-frequency / inter-system frequency measurements during cell reselection.
[0259] Threshold 4 and threshold 5 can be the same (i.e., threshold 5 is threshold 4). Threshold 4 and threshold 5 can also be different; for the specific meaning of "different", please refer to the above explanation of the difference between threshold 1 and threshold 2.
[0260] Optionally, the calculated result between threshold 5 and bias value 3 is greater than threshold 5.
[0261] Alternatively, the threshold 6 mentioned above can be provided by a second parameter. That is, the second parameter can include threshold 6, which can be used to trigger the initiation of low-priority or equal-priority inter-frequency / inter-system measurements during cell reselection. Threshold 6 is less than threshold 4, or threshold 6 is less than the calculated result between threshold 5 and offset value 3; wherein, threshold 6 can be the aforementioned threshold 5, and threshold 6 is less than the aforementioned threshold 4, and the aforementioned offset value 3 can be used to increase threshold 6 (that is, to increase threshold 5). Similarly, threshold 6 can include a signal amplitude threshold 6 for initiating inter-frequency / inter-system measurements, and / or a signal strength threshold 6 for initiating inter-frequency / inter-system measurements.
[0262] Taking the aforementioned threshold 4, which includes a signal amplitude threshold 4, and threshold 6, which includes a signal amplitude threshold 6, as an example, if the signal amplitude threshold 4 is greater than the threshold 6 for activating the signal amplitude, the bias value 3 corresponding to the signal amplitude can be used to increase the signal amplitude threshold 6. For instance, the calculated result between the bias value 3 corresponding to the signal amplitude and the signal amplitude threshold 6 is greater than the signal amplitude threshold 6. For example, if the bias value 3 corresponding to the signal amplitude is a positive number, the sum of the bias value 3 and the signal amplitude threshold 6 is greater than the signal amplitude threshold 6.
[0263] Taking the aforementioned threshold 4 as including a signal strength threshold 4 and threshold 6 as including a signal strength threshold 6 as an example, since the signal strength threshold 4 is greater than the signal strength threshold 6, the bias value 3 corresponding to the signal strength can be used to increase the signal strength threshold 6. For example, the calculated result between the bias value 3 corresponding to the signal strength and the signal strength threshold 6 is greater than the signal strength threshold 6.
[0264] Taking the above threshold 4, which includes signal amplitude threshold 4 and signal strength threshold 4, and threshold 6, which includes signal amplitude threshold 6 and signal strength threshold 6, as an example, the signal amplitude threshold 4 is greater than the signal amplitude threshold 6, and the signal strength threshold 4 is greater than the signal strength threshold 6.
[0265] Specifically, the bias value 3 corresponding to the signal amplitude is used to increase the signal amplitude threshold 6. The bias value 3 corresponding to the signal strength increases the signal strength threshold 6. For example, the sum of the bias value 3 corresponding to the signal amplitude and the signal amplitude threshold 6 is greater than the signal amplitude threshold 6, and the sum of the bias value 3 corresponding to the signal strength and the signal strength threshold 6 is greater than the signal strength threshold 6.
[0266] Optionally, the bias value 3 corresponding to the signal amplitude and the bias value 3 corresponding to the signal strength can be the same, that is, the bias value 3 corresponding to the signal strength can be the bias value 3 corresponding to the signal amplitude.
[0267] In some embodiments, the threshold 6 may be different from the threshold 5. The threshold 6 is still less than the threshold 4, and the threshold 6 is less than the calculated result between the threshold 5 and the bias value 3.
[0268] The above describes the thresholds (such as thresholds 4, 5, and 6) related to initiating low-priority or equal-priority inter-frequency / inter-system measurements. The following section uses the following as an example: threshold 4 includes a signal amplitude threshold 4 and a signal strength threshold 4; threshold 5 includes a signal amplitude threshold 5 and a signal strength threshold 5; threshold 6 includes a signal amplitude threshold 6 and a signal strength threshold 6; offset value 3 includes an offset value 3 corresponding to the signal amplitude and an offset value 3 corresponding to the signal strength; and the above calculation results are and , to introduce the method for a terminal to initiate low-priority or equal-priority inter-frequency / inter-system measurements using these thresholds.
[0269] When the terminal is a Class 1 terminal, initiate low-priority or equivalent-priority inter-frequency / inter-system frequency measurement according to the following method:
[0270] When Srxlev is greater than SnonIntraSearchPforNES and Squal is greater than SnonIntraSearchQforNES, the NES terminal does not initiate low-priority or equal-priority inter-frequency / inter-system frequency measurements. Otherwise, the NES terminal initiates low-priority or equal-priority inter-frequency / inter-system frequency measurements. Here, SnonIntraSearchPforNES represents a signal amplitude threshold of 4, and SnonIntraSearchQforNES represents a signal strength threshold of 4. Additionally, SnonIntraSearchPforNES can also be expressed as S... nonIntraSearchP It indicates that SnonIntraSearchQforNES can also be accessed via S nonIntraSearchQ This indicates that the NES terminal can still operate according to Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ Determine whether to initiate low-priority or equal-priority inter-frequency / inter-system frequency measurements, except that S here...nonIntraSearchP The value is the value of the signal amplitude threshold 4. S nonIntraSearchQ The value is the value of the signal strength threshold 4.
[0271] or,
[0272] When the serving cell satisfies Srxlev>S nonIntraSearchP +S offset3 And Squal>S nonIntraSearchQ +S offset4 When this occurs, the NES terminal will not activate a low-priority or equal-priority inter-frequency / inter-system frequency; otherwise, the NES terminal may activate a low-priority or equal-priority inter-frequency / inter-system frequency. Among these, S... offset3 This represents the bias value of 3 corresponding to the signal amplitude. offset4 The offset value of 3 represents the signal strength. nonIntraSearchP This indicates that the value can be either the signal amplitude threshold of 5, or S. nonIntraSearchQ It indicates or takes a value of 5, which represents the signal strength threshold.
[0273] or,
[0274] When the serving cell satisfies Srxlev>S nonIntraSearchP +S offset3 And Squal>S nonIntraSearchQ +S offset4 When this occurs, the NES terminal will not activate a low-priority or equal-priority inter-frequency / inter-system frequency; otherwise, the NES terminal may activate a low-priority or equal-priority inter-frequency / inter-system frequency. Among these, S... offset3 This represents the bias value of 3 corresponding to the signal amplitude. offset4 The offset value of 3 represents the signal strength. nonIntraSearchP This indicates that the value can be either the signal amplitude threshold of 6, or S. nonIntraSearchQ It indicates or takes a value of 6, which represents the signal strength threshold.
[0275] The first type of terminal obtains whether the inter-frequency / inter-system frequency is an NES cell through the second indication information. When the first indication information indicates that the first cell is an NES cell, and the first cell is included in the inter-frequency / inter-system frequency with low priority or equal priority, the above method can be executed.
[0276] In one possible design, the above method is used only when the inter-frequency / inter-system frequencies of lower or equal priority include NES cells; when the inter-frequency / inter-system frequencies of lower or equal priority do not include NES cells, the first type of terminal uses the following method for cell reselection, namely...
[0277] When the serving cell satisfies Srxlev>S nonIntraSearchP And Squal>SnonIntraSearchQ When this occurs, the NES terminal will not activate a low-priority or equal-priority inter-frequency / inter-system frequency; otherwise, the NES terminal may activate a low-priority or equal-priority inter-frequency / inter-system frequency. Among these, S... nonIntraSearchP This indicates that the value can be either the signal amplitude threshold of 6, or S. nonIntraSearchQ This indicates that the value can be either a signal strength threshold of 6. Where S... nonIntraSearchP This could be the signal amplitude threshold for initiating inter-frequency / inter-system measurements as described in S101 above, which is the same as the signal amplitude threshold for initiating inter-frequency / inter-system measurements in traditional cell reselection parameters. Similarly, S nonIntraSearchQ It can be the signal strength threshold for initiating inter-frequency / inter-system measurements as described in S101 above.
[0278] Additionally, when the terminal is a Type II terminal, low-priority or equivalent-priority inter-frequency / inter-system frequency measurement shall be initiated according to the following method:
[0279] When the serving cell satisfies Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ In this case, the second type of terminal will not activate low-priority or equal-priority inter-frequency / inter-system frequencies; otherwise, the traditional terminal can activate low-priority or equal-priority inter-frequency / inter-system frequencies. Among them, S... nonIntraSearchP This indicates that the value can be either the signal amplitude threshold of 6, or S. nonIntraSearchQ It indicates or takes a value of 6, which represents the signal strength threshold.
[0280] In this embodiment, the serving cell increases the probability that the corresponding S value is less than the threshold by increasing the threshold used to initiate low-priority inter-frequency / inter-system frequency measurements, thereby increasing the probability of initiating low-priority or equal-priority inter-frequency / inter-system frequency measurements, and thus increasing the likelihood that the NES terminal will perform cell reselection.
[0281] It is understandable that the neighboring cells described above, whether increasing the likelihood of initiating same-frequency measurements, increasing the likelihood of initiating low-priority or equal-priority inter-frequency / inter-system measurements, or increasing the likelihood of initiating inter-frequency / inter-system frequency measurements, all use the same frequency. The serving cell can also configure different frequency points for the same neighboring cell to adjust the neighboring cell's frequency point, thereby allowing the NES terminal to change the measurement method. For example, neighboring cell A may have one frequency point F1 and another frequency point F2, where F1 and F2 are different. The serving cell's frequency point is F1, and since neighboring cell A's frequency point includes F2, the NES terminal can initiate inter-frequency / inter-system frequency measurements. Alternatively, the neighboring cell's frequency point can also be adjusted using an offset value.
[0282] The process of adjusting the frequency points of neighboring cells can refer to the process of increasing the priority of frequency points of different frequencies / different systems described above. For example, the first parameter mentioned above can include the frequency point 1 of the neighboring cell. Frequency point 1 is used to initiate the measurement (or, in other words, to determine the method of initiating the measurement, whether it is a same-frequency measurement or a different-frequency / different system frequency measurement).
[0283] And / or, the first parameter includes the neighboring cell's frequency point 2 and offset value 4. Frequency point 2 and offset value 4 are used to initiate the measurement.
[0284] And / or, the first parameter includes an offset value of 4. The NES terminal can acquire frequency point 3, which, along with the offset value 4, is used to initiate the measurement.
[0285] Optionally, the aforementioned frequency point 3 can be provided by a second parameter, that is, the second parameter can include the frequency point 3 of a neighboring cell. Frequency point 3 is different from frequency point 1, or the calculation results of frequency point 3, frequency point 2, and offset value 4 are different; wherein, frequency point 3 can be the aforementioned frequency point 2, frequency point 3 is different from frequency point 1, and offset value 4 is used to adjust frequency point 3, and the adjusted frequency point 3 is different from frequency point 3.
[0286] It should be noted that the method for the terminal to initiate measurement based on the frequency point can refer to the relevant content on initiating the same-frequency strategy and different frequency / different system frequency introduced above, and will not be described again here.
[0287] In another possible implementation, as discussed above, determining whether to initiate intra-frequency measurement, or whether to initiate low-priority or equal-priority inter-frequency / inter-system frequency measurement, involves checking if the S-value is greater than the corresponding threshold. If the S-value is greater than the threshold, measurement is not initiated. Therefore, to relax the initiation of measurement, the serving cell can not only increase the threshold as described above to reduce the probability of the S-value being greater than the corresponding threshold, but also decrease the S-value to further reduce the probability of it being greater than the threshold.
[0288] Accordingly, the first parameter mentioned above may include parameter 1, which is used to determine the signal quality of the serving cell. Parameter 1 may include parameter 1 for determining the signal amplitude of the serving cell (or parameter 1 for determining the signal amplitude) and / or parameter 1 for determining the signal strength of the serving cell (or parameter 1 for determining the signal strength).
[0289] And / or, the first parameter includes parameter 2 and offset value 5, which are used to determine the signal quality of the serving cell. Parameter 2 may include parameter 2 for determining the signal amplitude of the serving cell (or parameter 2 for determining signal amplitude) and / or parameter 2 for determining the signal strength of the serving cell (or parameter 2 for determining signal strength). Offset value 5 includes offset value 5 corresponding to the signal amplitude and / or offset value 5 corresponding to the signal strength.
[0290] And / or, the first parameter includes an offset value of 5. The NES terminal can obtain parameter 3, which, along with the offset value 5, is used to determine the signal quality of the serving cell.
[0291] Parameter 2 and parameter 1 can be the same (i.e., parameter 2 is parameter 1), or they can be different.
[0292] Optionally, the offset value 5 can be used to reduce the signal quality of the serving cell determined based on parameter 2, where the signal quality of the serving cell determined based on parameter 2 is greater than the signal quality of the serving cell determined based on both parameter 2 and offset value 5.
[0293] Alternatively, parameter 3 may be provided by a second parameter, meaning the second parameter may include parameter 3, which can be used to determine the signal quality of the serving cell. The signal quality of the serving cell determined based on parameter 3 is greater than the signal quality of the serving cell determined based on parameter 1, or the signal quality of the serving cell determined based on parameter 3 is greater than the signal quality of the serving cell determined based on parameter 2 and offset value 5; wherein parameter 3 may be parameter 2, and the signal quality of the serving cell determined based on parameter 3 is greater than the signal quality of the serving cell determined based on parameter 1. Similarly, parameter 3 may include parameter 3 for determining the signal amplitude of the serving cell (or parameter 3 for determining the signal amplitude) and / or parameter 3 for determining the signal strength of the serving cell (or parameter 3 for determining the signal strength).
[0294] Taking the example where parameter 1 includes a parameter for determining the signal amplitude and parameter 3 includes a parameter for determining the signal amplitude, the signal amplitude obtained based on parameter 1 is less than the signal amplitude obtained based on parameter 3. The bias value 5 corresponding to the signal amplitude can be used to reduce the signal amplitude obtained based on parameter 3. For example, the signal amplitude obtained from the calculation result between the bias value 5 corresponding to the signal amplitude and parameter 3 for determining the signal amplitude is less than the signal amplitude obtained based on parameter 3.
[0295] Taking the example where parameter 1 includes parameter 1 for determining signal strength and parameter 3 includes parameter 3 for determining signal strength, if the signal strength obtained based on parameter 1 for determining signal strength is less than the signal strength obtained based on parameter 3 for determining signal strength, the bias value 5 corresponding to the signal strength can be used to reduce the signal strength obtained based on parameter 3 for determining signal strength. For example, the signal strength obtained from the calculation result between the bias value 5 corresponding to the signal strength and parameter 3 for determining signal strength is less than the signal strength obtained based on parameter 3 for determining signal strength.
[0296] Taking the above parameter 1, which includes parameter 1 for determining signal amplitude and parameter 1 for determining signal strength, and parameter 3, which includes parameter 3 for determining signal amplitude and parameter 3 for determining signal strength, as an example, the signal amplitude obtained based on parameter 1 for determining signal amplitude is less than the signal amplitude obtained based on parameter 3 for determining signal amplitude, and the signal strength obtained based on parameter 1 for determining signal strength is less than the signal strength obtained based on parameter 3 for determining signal strength.
[0297] Specifically, the bias value 5 corresponding to the aforementioned signal amplitude is used to reduce the signal amplitude obtained based on parameter 3, which determines the signal amplitude. The bias value 5 corresponding to the signal strength is used to reduce the signal amplitude obtained based on parameter 3, which determines the signal strength. For example, the signal amplitude obtained from the calculation result between the bias value 5 corresponding to the signal amplitude and parameter 3, which determines the signal amplitude, is less than the signal amplitude obtained based on parameter 3. The bias value 5 is only applied to cell reselection by the first type of terminal. When the first type of terminal performs cell selection, this value is 0 or not applied when calculating the S value.
[0298] Similarly, the signal strength obtained from the calculation based on the offset value 5 corresponding to the signal strength and the parameter 3 that determines the signal strength is less than the signal amplitude obtained based on the parameter 3 that determines the signal strength. The offset value 5 is only used by the first type of terminal for cell reselection. When the first type of terminal performs cell selection, this value is 0 or not applied when calculating the S value.
[0299] In some embodiments, the parameter 1 for determining the signal amplitude may include one or more of the following: signal reception level value 1 of the cell under test, minimum signal reception level value 1 of the cell under test, bias value 1 of the cell signal reception level when switching from VPLMN to a higher priority PLMN, temporary bias value 1A, and power compensation value 1.
[0300] The parameter 1 for determining the signal strength mentioned above may include one or more of the following: the signal reception quality value of the cell under test 1, the minimum value of the cell signal reception quality value 1, the bias value of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN, and the temporary bias value 1B.
[0301] Similarly, the parameter 2 for determining the signal amplitude mentioned above may include one or more of the following: the signal reception level value 2 of the cell under test, the minimum value 2 of the signal reception level value of the cell under test, the offset value 2 of the cell signal reception level value when switching from VPLMN to a higher priority PLMN, the temporary offset value 2A, and the power compensation value 2.
[0302] The parameter 2 for determining the signal strength mentioned above may include one or more of the following: the signal reception quality value of the cell under test 2, the minimum value of the cell signal reception quality value 2, the bias value of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN, and the temporary bias value 2B.
[0303] The parameter 3 for determining the signal amplitude mentioned above may include one or more of the following: the signal reception level value 3 of the cell under test, the minimum value 3 of the signal reception level value of the cell under test, the offset value 3 of the cell signal reception level value when switching from VPLMN to a higher priority PLMN, the temporary offset value 3A, and the power compensation value 3.
[0304] The parameter 3 for determining the signal strength mentioned above may include one or more of the following: the signal reception quality value of the cell under test 3, the minimum value of the cell signal reception quality value 3, the bias value of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN, and the temporary bias value 3B.
[0305] The signal quality of the serving cell determined based on parameter 3 is greater than that of the serving cell determined based on parameter 1, or the signal quality of the serving cell determined based on parameter 3 is greater than that of the serving cell determined based on parameter 2 and offset value 5. For example, the fact that the signal quality of the serving cell determined based on parameter 3 is greater than that of the serving cell determined based on parameter 1 can be specifically defined as follows: the minimum value 1 of the signal reception level of the tested cell is greater than the minimum value 3 of the signal reception level of the tested cell; the offset value 1 of the cell signal reception level when switching from VPLMN to a higher priority PLMN is greater than the offset value 3 of the cell signal reception level when switching from VPLMN to a higher priority PLMN; and the temporary offset value 1A is greater than the temporary offset value 3A.
[0306] Furthermore, the difference between parameter 2 and parameter 1 can indicate that parameter 2 for determining the signal amplitude differs from one or more parameters in parameter 1. For example, parameter 2 may include parameter 2 for determining the signal amplitude, and parameter 1 may include parameter 1 for determining the signal amplitude. Parameter 2 for determining the signal amplitude includes the signal reception level value 2 of the tested cell, the minimum signal reception level value 2 of the tested cell, the offset value 2 of the cell's signal reception level when switching from VPLMN to a higher priority PLMN, the temporary offset value, and the power compensation value 2.
[0307] The parameter 1 for determining the signal amplitude includes the signal reception level value 1 of the cell under test, the minimum value 1 of the signal reception level value of the cell under test, the offset value 1 of the cell signal reception level value when switching from VPLMN to a higher priority PLMN, the temporary offset value, and the power compensation value 1.
[0308] The signal reception level value 2 of the tested cell is different from the signal reception level value 1 of the tested cell, while the other parameters in parameter 2 that determines the signal amplitude are the same as the other parameters in parameter 1 that determines the signal amplitude.
[0309] It should be noted that, in the embodiments of this application, for parameters used to trigger the start of measurement and / or perform cell selection evaluation, if the first parameter is configured, the parameter configured in the first parameter can be used; if the first parameter is not configured, other parameters (such as the second parameter, or traditional cell reselection parameters) can use the parameter configured in other parameters. Taking the parameter required to calculate the signal amplitude as an example, if the first parameter is configured, the parameter configured in the first parameter is used; if the first parameter is not configured, but the second parameter is configured, the parameter configured in the second parameter can be used. Simply put, if the required parameter is not found in the first parameter, it can be directly searched for in other parameters. For example, calculating the signal amplitude requires using Q... rxlevmeas Q rxlevmin Q rxlevminoffse、 P compensation Qoffset temp The first parameter is configured with Q. rxlevmeas Q was not configured rxlevmin Q rxlevminoffse、 P compensation Qoffset temp Therefore, the signal amplitude can be calculated using the signal reception quality value 1 of the cell under test configured by the first parameter, the minimum value 3 of the signal reception level of the cell under test configured by the third parameter, the offset value 3 of the cell signal reception level when switching from VPLMN to a higher priority PLMN, the temporary offset value 3A, and the power compensation value 3.
[0310] In some embodiments, parameter 3 may be different from parameter 2.
[0311] The above describes the parameters (such as parameters 1, 2, and 3) used to determine the signal quality related to initiating measurement. Initiating measurement can be initiating same-frequency measurement, or low-priority or equal-priority inter-frequency / inter-system frequency measurement. The following example uses same-frequency measurement as the starting point, where parameter 1 includes parameters for determining signal amplitude and signal strength; parameter 2 includes parameters for determining signal amplitude and signal strength; parameter 3 includes parameters for determining signal amplitude and signal strength; and offset value 5 includes offset values corresponding to signal amplitude and signal strength. The calculated result is the difference. This example illustrates how the terminal uses these parameters to initiate same-frequency measurement.
[0312] When the terminal is a Class I terminal, the same-frequency measurement is performed according to the following method:
[0313] First, the NES terminal can calculate the signal amplitude of the serving cell using the following method:
[0314] The NES terminal can use formula seven, Srxlev = Q. rxlevmeasforNES -(Q rxlevminforNES +Q rxlevminoffsetforNES )-P compensationforNES -QoffsettempforNES calculates Srxlev. Where Q rxlevmeasforNES This indicates the signal reception level value of the tested cell (or Q). rxlevmeasforNES The value of Q is the signal reception level of the cell being tested (1), Q rxlevminforNES Q represents the minimum value of the signal reception level of the tested cell, 1. rxlevminoffsetforNES P represents the offset value of the cell signal reception level of 1 when switching from VPLMN to a higher priority PLMN. compensationforNES This indicates a power compensation value of 1, and QoffsettempforNES indicates a temporary bias value of 1A. Alternatively,
[0315] The NES terminal can use Formula 1 above, Srxlev = Q. rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp Calculate Srxlev. Where Q rxlevmeas The value is 1, which represents the signal reception level of the cell being tested. Furthermore, this value is measured by the UE and is generally not configured on the network side. Q rxlevmin The value of Q is the minimum value of the signal reception level of the tested cell, which is 1; rxlevminoffset The value is 1, which is the offset value of the cell signal reception level when switching from VPLMN to a higher priority PLMN. compensation The value of Qoffset is 1, which is the power compensation value. temp The value is a temporary bias value of 1A. Additionally, it should be understood that if the parameter required by Formula 1 is configured in the first parameter, that parameter can be used directly; otherwise, it can be obtained from the third parameter. For example, if the first parameter is configured with a signal reception level value of 1, Q... rxlevmeas The value of Q is the signal reception level of the tested cell, which is 1. If not configured, Q... rxlevmeas The value can be the signal reception level of the tested cell, 3.
[0316] or,
[0317] The NES terminal can use formula eight, Srxlev = Q. rxlevmeas -(Q rxlevmin +Qrxlevminoffset )-P compensation -Qoffset temp -Qoffset forNESP Calculate Srxlev. Where Q rxlevmeas The signal reception level value of the tested cell is represented by 2, Q. rxlevmin Q represents the minimum value of the signal reception level of the tested cell, 2. rxlevminoffset This represents the offset value of 3, P, when switching from VPLMN to a higher priority PLMN. compensation Indicates a power compensation value of 2, Qoffset temp This represents a temporary bias value of 2A. Qoffset forNESP This indicates the bias value of 5 corresponding to the signal amplitude.
[0318] Alternatively, the NES terminal can use formula eight, Srxlev = Q. rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp -Qoffset forNESP Calculate Srxlev. Where Q rxlevmeas The signal reception level of the tested cell is represented by 3, Q. rxlevmin Q represents the minimum signal reception level of the tested cell, 3. rxlevminoffset This represents the offset value of 3, P, when switching from VPLMN to a higher priority PLMN. compensation Indicates a power compensation value of 3, Qoffset temp This represents a temporary bias value of 3A. Qoffset forNESP This indicates the bias value of 5 corresponding to the signal amplitude.
[0319] Wherein, the signal reception level value 3 of the tested cell can be the signal reception level value of the tested cell in the corresponding content of S101 above. The minimum signal reception level value 3 of the tested cell can be the minimum signal reception level value of the tested cell in the corresponding content of S101 above. The offset value 3 of the cell signal reception level value when switching from VPLMN to a higher priority PLMN can be the offset value of the cell signal reception level value when switching from VPLMN to a higher priority PLMN in the corresponding content of S101 above. The power compensation value 3 can be the power compensation value in the corresponding content of S101 above. The temporary offset value 3A can be the temporary offset value in the corresponding content of S101 above.
[0320] Alternatively, the aforementioned power compensation value 3 can also be calculated using the relevant formulas introduced earlier, only with a different value. Alternatively, a new formula can be used, where the parameters are configured differently from the traditional parameters, such as QoffsettempforNES, Q... qualminforNES Q qualminoffsetforNES Instead of using Qoffset temp Q qualmin Q qualminoffset The specific process can be found in Srxlev's calculation process, which will not be repeated here.
[0321] Similarly, the NES terminal can calculate the signal amplitude of the serving cell using the following method:
[0322] NES terminals can use the common nine, where Squal = Q. qualmeasfornes -(Q qualminfornes +Q qualminoffsetfornes )-Q offsettempfornes Calculate Squal, where Q is the constant. qualmeasfornes Q represents the signal reception quality value of the tested cell (1). qualminfornes Q represents the minimum value of the cell signal reception quality. qualminoffsetfornes Q represents the offset value of the cell signal reception quality when switching from VPLMN to a higher priority PLMN. offsettempfornes This represents a temporary bias value of 1B.
[0323] or,
[0324] NES terminals can use formula four above, Squal = Q. qualmeas -(Q qualmin +Q qualminoffset -Qoffset temp Calculate Squal, where Q is the constant. qualmeas The value of Q is the signal reception quality value of the cell under test. qualmin The value of Q is the minimum value of the cell signal reception quality, which is 1. qualminoffset The value of Qoffset is a 1-fold offset of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN. temp The value is a temporary bias value of 1B.
[0325] or,
[0326] The NES terminal can use formula ten, Squal = Q. qualmeas –(Q qualmin +Q qualminoffset -Qoffset temp -Qoffset forNESQ Calculate Squal, where Q is the constant.qualmeas The Q value represents the signal reception quality of the tested cell. qualmin Q represents the minimum value of the cell signal reception quality, 2. qualminoffset The value of Qoffset is a 2-fold offset of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN. temp The value of Qoffset is a temporary bias value of 2B. forNESQ The value 5 represents the offset value corresponding to the signal strength.
[0327] or,
[0328] The NES terminal can use formula ten, Squal = Q. qualmeas –(Q qualmin +Q qualminoffset -Qoffset temp -Qoffset forNESQ Calculate Squal, where Q is the constant. qualmeas The measured cell signal reception quality value is 3, Q. qualmin Q represents the minimum value of the cell signal reception quality, 3. qualminoffset The value of Qoffset is an offset of 3, representing the cell signal reception quality value when switching from VPLMN to a higher priority PLMN. temp The value is a temporary bias value of 3B, Qoffset forNESQ The value 5 represents the offset value corresponding to the signal strength.
[0329] Among them, the measured cell signal reception quality value 3 can be the traditional measured cell signal reception quality value introduced above. The minimum cell signal reception quality value 3 can be the minimum cell signal reception quality value in the traditional cell reselection parameters. The offset value 3 of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN can be the traditional offset value of the cell signal reception quality value when switching from VPLMN to a higher priority PLMN. The temporary offset value 3B can be the traditional temporary offset value.
[0330] The NES terminal then uses Squal and Srxlev to determine whether to initiate co-frequency measurement.
[0331] The first type of terminal obtains whether the co-frequency cell is an NES cell through the first indication information. When the first indication information indicates that the first cell is an NES cell and the first cell is included in the co-frequency cell, the above method for determining Squal and Srxlev can be executed.
[0332] In one possible design, the above method is used only when the co-frequency cell includes an NES cell; when the co-frequency cell does not include an NES cell, the first type of terminal uses the following method for cell reselection, namely...
[0333] First, the NES terminal uses Formula 1, Srxlev = Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp Calculate Srxlev. Where Q rxlevmeas The signal reception level of the tested cell is represented by 3, Q. rxlevmin Q represents the minimum signal reception level of the tested cell, 3. rxlevminoffset The value of P represents the offset value of the cell signal reception level when switching from VPLMN to a higher priority PLMN. compensation The value of Qoffset is represented by the power compensation value. temp The value of is a temporary bias value representing A.
[0334] And, using Formula 4, Squal = Q qualmeas -(Q qualmin +Q qualminoffset -Qoffset temp Calculate Squal, where Q is the constant. qualmeas The measured cell signal reception quality value is 3, Q. qualmin Q represents the minimum value of the cell signal reception quality, 3. qualminoffset Qoffset represents the offset value of the cell signal reception quality when switching from VPLMN to a higher priority PLMN, where 3 is the offset value. temp This represents a temporary bias value of 3B.
[0335] The NES terminal then uses Squal and Srxlev to determine whether to initiate co-frequency measurement.
[0336] Additionally, when the terminal is a type II terminal, the same-frequency measurement should be initiated using the following method:
[0337] First, traditional terminals use Formula 1, Srxlev=Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp Calculate Srxlev. Where Q rxlevmeas The signal reception level of the tested cell is represented by 3, Q. rxlevmin Q represents the minimum signal reception level of the tested cell, 3. rxlevminoffsetThis represents the offset value of 3, P, when switching from VPLMN to a higher priority PLMN. compensation Indicates a power compensation value of 3, Qoffset temp The temporary bias value is represented as 3A.
[0338] And, using Formula 4, Squal = Q qualmeas -(Q qualmin +Q qualminoffset -Qoffset temp Calculate Squal, where Q is the constant. qualmeas The measured cell signal reception quality value is 3, Q. qualmin Q represents the minimum value of the cell signal reception quality, 3. qualminoffset Qoffset represents the offset value of the cell signal reception quality when switching from VPLMN to a higher priority PLMN, where 3 is the offset value. temp This represents a temporary bias value of 3B.
[0339] Subsequently, traditional terminals use Squal and Srxlev to determine whether to initiate co-frequency measurement.
[0340] In this embodiment of the application, the serving cell increases the likelihood that the S value of the serving cell is less than the corresponding threshold by reducing the S value, thereby increasing the likelihood of initiating measurement.
[0341] In another possible implementation, the first parameter may also include parameters related to the serving cell configuration and cell reselection execution.
[0342] 1) The neighboring cells of the serving cell of the terminal include co-frequency cells or inter-frequency / inter-system frequency cells with the same priority. According to the above, if the current serving cell stay time is greater than time 5, and the duration of Rn of the co-frequency cell or inter-frequency / inter-system frequency with the same priority is greater than or equal to the time interval 5 of Rs of the current serving cell, then the co-frequency cell or inter-frequency / inter-system frequency with the same priority can be used as a candidate cell.
[0343] Therefore, to relax cell reselection assessment, in one design approach, time 5 can be shortened. Accordingly, the first parameter may include time 5A, which is used to perform cell reselection assessment and represents the time threshold required to exceed the dwell time in the serving cell.
[0344] And / or, the first parameter may include time 5B and bias value 6. Time 5B and bias value 6 are used to perform cell reselection assessment, and time 5B and bias value 6 represent the time threshold required to stay in the serving cell.
[0345] And / or, the first parameter may include an offset value of 6. The NES terminal may acquire the parameter time 5C. Time 5C and offset value 6 are used to perform cell reselection assessment, and time 5C and offset value 6 represent the time threshold required to stay in the serving cell.
[0346] Wherein, time 5B can be time 5A, or time 5A and time 5B are different.
[0347] Optionally, the aforementioned bias value 6 is used to shorten time 5B. For example, the calculated result between the bias value 6 and time 5B is less than time 5B.
[0348] Alternatively, the aforementioned time 5C may be provided by a second parameter, that is, the aforementioned second parameter may include time 5C, which is used to perform cell reselection assessment.
[0349] Time 5C can be greater than time 5A, or time 5C can be less than the calculated result between time 5B and offset value 6; wherein time 5C can be the aforementioned time 5B, and time 5C is greater than the aforementioned time 5A, and the aforementioned offset value 6 is used to shorten time 5C. For example, the calculated result between offset value 6 and time 5C is less than time 5C.
[0350] To avoid redundancy, the descriptions of time 5A, time 5B, time 5C, and offset value 6 mentioned above can be found in the relevant content of the implementation method for increasing the priority of different frequency / different system frequency introduced above.
[0351] In this design, by shortening the time by 5, the NES terminal can stay in the current serving cell for a shorter period of time, relax cell reselection, and enable the NES terminal to quickly reselect to an NES cell.
[0352] In another design approach, the time interval 5 can be shortened. Accordingly, the first parameter can include the time interval 5A, which is used to perform cell reselection assessment and represents the time threshold required to achieve the duration of Rn > Rs.
[0353] And / or, the first parameter may include a time interval 5B and an offset value 7. The time interval 5B and the offset value 7 are used to perform cell reselection assessment, and the time interval 5B and the offset value 7 represent the time threshold required to achieve the duration of Rn > Rs.
[0354] And / or, the first parameter may include an offset value of 7. The NES terminal may obtain the parameter time interval 5C. The time interval 5C and the offset value 7 are used to perform cell reselection assessment, and the time interval 5C and the offset value 7 represent the time threshold required to achieve the duration of Rn > Rs.
[0355] Wherein, the aforementioned time interval 5B can be the aforementioned time interval 5A, or the time interval 5A and the time interval 5B are different.
[0356] Alternatively, the aforementioned time interval 5C can be provided by a second parameter, meaning the second parameter can include time interval 5C, which is used to perform cell reselection assessment. Time interval 5C can be greater than time interval 5A, or time interval 5C can be less than the calculated result between time interval 5B and the bias value 7; wherein time interval 5C can be the aforementioned time interval 5B, and time interval 5C is greater than the aforementioned time interval 5A, and the aforementioned bias value 7 is used to shorten time interval 5C. For example, the calculated result between the bias value 7 and time interval 5C is less than time interval 5C.
[0357] To avoid redundancy, the descriptions of time intervals 5A, 5B, 5C, and offset value 7 can also be found in the section on improving the priority of different frequencies / different systems described above.
[0358] In some embodiments, the process of the terminal performing cell reselection evaluation using the aforementioned time 5 and time interval 5 can refer to the relevant description of the measurement initiation method introduced above. For example, when the terminal is a type 1 terminal, the cell reselection evaluation is performed according to the following method: if the camping time of the current serving cell is greater than time 5, if the duration of Rn of the same frequency cell or the frequency of the same priority inter-frequency / inter-system cell is greater than the duration of Rs of the current serving cell is greater than or equal to Treselection. RATforNES Then, the same-frequency cell, or a different-frequency / different-system frequency of equal priority, can be used as a candidate cell. RATforNES Indicates a time interval of 5A. Treselection RATforNES Alternatively, it can be replaced with a description of Treselection. RAT Treselection RAT The value is the time interval 5A.
[0359] In this design, by shortening the time interval by 5, the duration for which Rn is greater than Rs is reduced, eliminating the need to maintain high signal quality for an extended period. This increases the likelihood of the NES terminal reselecting to an NES cell and enables the NES terminal to quickly reselect to an NES cell.
[0360] In another design approach, Rn can be increased. Accordingly, the first parameter mentioned above can include parameter 4, which is used to determine Rn for the same-frequency cell or the frequency of the different frequency / different system with the same priority.
[0361] And / or, the first parameter includes parameter 5 and offset value 8, which are used to determine Rn of the same frequency cell or the frequency of different frequency / different system with the same priority.
[0362] And / or, the first parameter includes an offset value of 8. The NES terminal can obtain parameter 6, which, along with the offset value 8, is used to determine Rn for the same-frequency cell or the frequency of a different frequency / system with the same priority.
[0363] Parameter 5 and parameter 4 can be the same (i.e., parameter 4 is parameter 5), or they can be different.
[0364] Optionally, the Rn determined based on parameter 5 is less than the Rn determined based on parameter 5 and bias value 7.
[0365] Optionally, parameter 6 can be provided by a second parameter. That is, the second parameter can include parameter 6, which can be used to determine Rn for frequencies of the same frequency cell or different frequency / system with equal priority. Rn determined based on parameter 6 is less than Rn determined based on parameter 4, or Rn determined based on parameter 6 is less than Rn determined based on parameter 5 and offset value 7. For example, Rn determined based on parameter 6 being less than Rn determined based on parameter 4 can specifically mean that offset value 1 is less than offset value 3; and temporary offset value 4A is less than temporary offset value 6A.
[0366] Among them, parameter 6 can be parameter 5 above, and Rn determined based on parameter 6 is less than Rn determined based on parameter 4. The bias value 8 above can be used to increase Rn determined based on parameter 6.
[0367] In some embodiments, parameter 4 may include one or more of the RSRP value 1, offset value 1, and temporary offset value 2A of the same frequency cell or the frequency of the different frequency / different system with the same priority. The parameters included in parameters 5 and 6 can be referred to the parameters included in parameter 4, and will not be repeated here.
[0368] Additionally, for information regarding parameters 4, 5, 6, and bias value 8, please refer to the information regarding parameters 1, 2, 3, and bias value 5 described above.
[0369] In some embodiments, the terminal can use the parameters described above (such as parameters 4, 5, and 6) to determine Rn. The process of the terminal determining Rn will be described below.
[0370] When the terminal is a Type I terminal, the NES terminal can calculate Rn using the following method:
[0371] The NES terminal can use formula eleven, R n =Q meas,nfornes -Qoffsetfornes -Qoffsettempfornes calculates Rn. Where Q meas,nfornes The RSRP value of 1 represents the frequency of a cell with the same frequency or a different frequency / system with the same priority. fornes Qoffsettempfornes represents an offset value of 1, and Qoffsettempfornes represents a temporary offset value of 4A.
[0372] or,
[0373] The NES terminal can use formula six above, R n =Q meas,n -Qoffset-Qoffset temp Calculate R n Among them, Q meas,n The value of is the RSRP value of a cell with the same frequency or a frequency of the same priority but different frequency / system, which is 1. The value of Qoffset is the offset value of 1. temp The value is a temporary bias value of 4A.
[0374] or,
[0375] The NES terminal can use formula twelve, R n =Q meas,n -Qoffset-Qoffset temp +Qoffset fornes1 Calculate R n Among them, Q meas,n The RSRP value of 2 represents the frequency of a cell with the same frequency or a different frequency / system with the same priority. Qoffset represents the offset value of 2. temp This represents a temporary bias value of 5A. Qoffset fornes1 This indicates a bias value of 8.
[0376] It is a positive number.
[0377] The NES terminal can use formula twelve, R n =Q meas,n -Qoffset-Qoffset temp +Qoffset fornes1 Calculate R n Among them, Q meas,n The RSRP value of 3 represents the frequency of a cell with the same frequency or a different frequency / system with the same priority. Qoffset represents the offset value of 3. temp This indicates a temporary bias value of 6A. Qoffset fornes1 This indicates a bias value of 8.
[0378] Among them, RSRP value 3 can be the RSRP value of a cell with the same frequency or a frequency of the same priority but different frequency / system in the content corresponding to S102 above. That is, the RSRP value of a cell with the same frequency or a frequency of the same priority but different frequency / system in the traditional cell reselection parameters. Offset value 3 is the offset value in the traditional cell reselection parameters. Temporary offset value 6A is the temporary offset value in the traditional cell reselection parameters.
[0379] Among them, the first type of terminal can obtain whether the cell with the same frequency or the cell with the same priority but different frequency / different system frequency is an NES cell through relevant indication information. When the indication information indicates that the first cell is an NES cell, and the first cell is included in the cell with the same frequency, the above method for determining Rn can be executed.
[0380] In one possible example, the method for determining Rn described above is used only when the co-frequency cell or the inter-frequency / inter-system frequency cell of equal priority includes an NES cell; when the co-frequency cell or the inter-frequency / inter-system frequency cell of equal priority does not include an NES cell, the first type of terminal uses the following method to determine Rn, namely...
[0381] The NES terminal uses formula six above, R n =Q meas,n -Qoffset-Qoffset temp Calculate R n Among them, Q meas,n The value of is the RSRP value of a cell with the same frequency or a frequency of the same priority but different frequency / system, which is 3. The value of Qoffset is the offset value of 3. temp The value is a temporary bias value of 6A.
[0382] Additionally, when the terminal is a type 2 terminal, Rn is determined according to the following method:
[0383] The second type of terminal adopts formula six above, R n =Q meas,n -Qoffset-Qoffset temp Calculate R n Among them, Q meas,n The value of is the RSRP value of a cell with the same frequency or a frequency of the same priority but different frequency / system, which is 3. The value of Qoffset is the offset value of 3. temp The value is a temporary bias value of 6A.
[0384] In another design approach, Rs can be reduced. Accordingly, the first parameter mentioned above can include parameter 7, which is used to determine the Rs of the serving cell.
[0385] And / or, the first parameter includes parameter 8 and bias value 9, which are used to determine the Rs of the serving cell.
[0386] And / or, the first parameter includes an offset value 9. The NES terminal can obtain parameter 9, which, along with the offset value 9, is used to determine the Rs of the serving cell.
[0387] Parameter 8 and parameter 7 can be the same (i.e., parameter 8 is parameter 7), or they can be different.
[0388] Optionally, the aforementioned bias value 9 can be used to reduce the Rs determined based on parameter 8. Optionally, the aforementioned parameter 9 can be provided by a second parameter, that is, the aforementioned second parameter can include parameter 9, which can be used to determine the Rs of the serving cell. The Rs determined based on parameter 9 is greater than the Rs determined based on parameter 7, or the Rs determined based on parameter 9 is greater than the Rs determined based on parameter 8 and bias value 9; the Rs determined based on parameter 9 being greater than the Rs determined based on parameter 7 can be, for example, the hysteresis value 1 of the serving cell being less than the hysteresis value 3 of the serving cell; the temporary bias value 4B being greater than the temporary bias value 6B. To avoid redundancy, other related descriptions can also refer to this section or similar related content above regarding the determination of R.
[0389] Among them, parameter 9 can be parameter 8 above, and Rs determined based on parameter 9 is greater than Rs determined based on parameter 7. The bias value 9 can be used to reduce Rs determined based on parameter 9.
[0390] In some embodiments, parameter 7 may include one or more of the serving cell's RSRP value 1, the serving cell's hysteresis value 1, and the temporary bias value 4B. The parameters included in parameters 8 and 9 can be referenced from those included in parameter 7, and will not be repeated here.
[0391] In addition, the relevant information about parameters 7, 8, 9 and bias value 9 can be found in the information about parameters 1, 2, 3 and bias value 5 introduced above.
[0392] In some embodiments, the terminal can use the parameters described above (such as parameters 7, 8, and 9) to determine the aforementioned Rs. The process of the terminal determining Rs will be described below.
[0393] When the terminal is a Type I terminal, the NES terminal can calculate Rs using the following method:
[0394] The NES terminal can use formula thirteen, Rs = Q. meas,sfornes +Q hystfornes -Qoffsettempfornes. Where Q... meas,sfornesIndicates the RSRP value of the serving cell as 1, Q hystfornes Qoffsettempfornes represents the hysteresis value of the serving cell as 1, and Qoffsettempfornes represents the temporary bias value as 4B.
[0395] or,
[0396] The NES terminal can use formula five above, Rs = Q. meas,s +Q hyst -Qoffset temp Among them, Q meas,s The value of Q is the RSRP value of the serving cell, which is 1. hyst The value of Qoffset is the hysteresis value of the serving cell, which is 1. temp The value is a temporary bias value of 4B.
[0397] or,
[0398] The NES terminal can use Formula Fourteen, Rs = Q meas,s +Q hyst -Qoffset temp -Qoffset fornes2 Among them, Q meas,s The value of the serving cell is represented by RSRP 2, Q. hyst Qoffset represents the hysteresis value of the serving cell, which is 2. temp This represents a temporary bias value of 5B. Qoffset fornes2 This indicates a bias value of 9.
[0399] or,
[0400] The NES terminal can use Formula Fourteen, Rs = Q meas,s +Q hyst -Qoffset temp -Qoffset fornes2 Among them, Q meas,s The value of the serving cell is 3, Q. hyst Qoffset represents the hysteresis value of the serving cell, which is 3. temp This represents a temporary bias value of 6B. Qoffset fornes2 This indicates a bias value of 9. A bias value of 9 is a positive number.
[0401] Among them, the RSRP value 3 of the serving cell can be the RSRP value of the serving cell in the corresponding content of S102 above. That is, the RSRP value of the serving cell in the traditional cell reselection parameters. The hysteresis value 3 of the serving cell is the hysteresis value of the serving cell in the traditional cell reselection parameters. The temporary bias value 6B is the temporary bias value in the traditional cell reselection parameters.
[0402] Among them, the first type of terminal can obtain whether the cell with the same frequency or the cell with the same priority but different frequency / different system frequency is an NES cell through relevant indication information. When the indication information indicates that the first cell is an NES cell and the first cell is included in the cell with the same frequency, the above method for determining Rs can be executed.
[0403] In one possible example, the method for determining Rs described above is used only when NES cells are included in the co-frequency cells or inter-frequency / inter-system frequency cells of equal priority; when NES cells are not included in the co-frequency cells or inter-frequency / inter-system frequency cells of equal priority, the first type of terminal uses the following method to determine Rs, namely...
[0404] The NES terminal uses formula five above, Rs = Q meas,s +Q hyst -Qoffset temp Among them, Q meas,s The value of the serving cell is 3, Q. hyst Qoffset represents the hysteresis value of the serving cell, which is 3. temp This represents a temporary bias value of 6B.
[0405] Additionally, when the terminal is a type 2 terminal, Rn is determined according to the following method:
[0406] The second type of terminal uses formula five above, Rs = Q meas,s +Q hyst -Qoffset temp Among them, Q meas,s The value of the serving cell is 3, Q. hyst Qoffset represents the hysteresis value of the serving cell, which is 3. temp This represents a temporary bias value of 6B.
[0407] It is understandable that the terminal may use one or more of the above design methods to perform cell reselection evaluation, thereby relaxing the cell reselection evaluation.
[0408] 2) The neighboring cells of the serving cell of the terminal include high-priority inter-frequency / inter-system frequency cells. As can be seen from the above, in one case, when threshServingLowQ is configured, if the time spent in the current serving cell is greater than time interval 1, and if the duration of the Squal of the high-priority inter-frequency / inter-system frequency cell is greater than the reselection high-intensity threshold is greater than the time interval 1, then the terminal can reselect to the high-priority inter-frequency / inter-system frequency cell.
[0409] Therefore, similar to the above, in order to relax cell reselection assessment, one design approach can shorten time 1. Accordingly, the first parameter can include time 1A, which is used to perform cell reselection assessment and represents the time threshold required to exceed the dwell time in the serving cell.
[0410] And / or, the first parameter may include time 1B and bias value 10. Time 1B and bias value 10 are used to perform cell reselection assessment, and time 1B and bias value 10 represent the time threshold required to stay in the serving cell.
[0411] And / or, the first parameter may include an offset value of 10. The NES terminal may acquire the parameter time 1C. Time 1C and offset value 10 are used to perform cell reselection assessment, and time 1C and offset value 10 represent the time threshold required to stay in the serving cell.
[0412] Wherein, time 1B can be time 1A, or time 1A and time 1B are different.
[0413] Optionally, an offset value of 10 is used to shorten time 1B.
[0414] Alternatively, the aforementioned time 1C can be provided by a second parameter, meaning the second parameter can include time 1C, which is used to perform cell reselection assessment. Time 1C is greater than the aforementioned time 1A, or time 1C is less than the calculated result between time 1B and offset value 10; wherein time 1C can be the aforementioned time 1B, and time 1C is greater than the aforementioned time 1A, and the aforementioned offset value 10 is used to shorten time 1C. For example, the calculated result between offset value 10 and time 1C is less than time 1C. To avoid redundancy, the relevant descriptions of the aforementioned time 1A, time 1B, time 1C, and offset value 11 can be found in the relevant content of the above-described implementation method for improving the priority of inter-frequency / inter-system frequencies.
[0415] In another design approach, the time interval 1 can be shortened. Accordingly, the first parameter may include time 1A, which is used to perform cell reselection assessment. Time 1A represents the time threshold required for a high-priority inter-frequency / inter-system frequency cell to have a Squal greater than the high-intensity reselection threshold.
[0416] And / or, the first parameter may include a time interval 1B and an offset value 11. The time interval 1B and the offset value 11 are used to perform cell reselection assessment.
[0417] And / or, the first parameter may include an offset value 11. The NES terminal may acquire a parameter time interval 1C. The time interval 1C and the offset value 11 are used to perform cell reselection assessment.
[0418] Wherein, the aforementioned time interval 1B can be the aforementioned time interval 1A, or the time interval 1A and time interval 1B are different.
[0419] Optionally, the calculated result between the bias value 11 and time 1B is less than time 1B.
[0420] Alternatively, the aforementioned time interval 1C can be provided by a second parameter. That is, the second parameter can include time interval 1C, which is used to perform cell reselection assessment. Time interval 1C is greater than time interval 1A, or time interval 1C is less than the calculated result between time interval 1B and bias value 11. Here, time interval 1C can be time interval 1B, and time interval 1C is greater than time interval 1A. The bias value 11 is used to shorten time interval 1C. For example, the calculated result between bias value 11 and time interval 1C is less than time interval 1C. The process of shortening time interval 1C can be referred to the process of shortening time interval 1 and time interval 5 described above, and will not be repeated here.
[0421] In some embodiments, the process of the terminal performing cell reselection evaluation using the aforementioned time 1 and time interval 1 can refer to the relevant description of the measurement initiation method introduced above. For example, when the terminal is a type 1 terminal, the cell reselection evaluation is performed according to the following method: When threshServingLowQ is configured, if the time spent in the current serving cell is greater than time 1, and the Squal of the high-priority inter-frequency / inter-system frequency cell is greater than Thresh... X,HighQ The duration is longer than Treselection RATforNES Then the terminal can reselect to that high-priority inter-frequency / inter-system frequency cell. RATforNES This indicates that the value can be a time interval of 1A. Treselection RATforNES Alternatively, it can be replaced with a description of Treselection. RAT Treselection RAT The value is the time interval 1A.
[0422] In another design approach, the high-intensity reselection threshold can be lowered. The process of lowering the high-intensity reselection threshold can be...
[0423] Referring to the process described above regarding lowering the threshold used to initiate the same-frequency measurement, it will not be repeated here.
[0424] Furthermore, the process by which the aforementioned terminal performs cell reselection assessment using the aforementioned high-intensity reselection threshold can be referenced from the description of the initiation measurement method above. For example, the value of the lowered high-intensity reselection threshold mentioned above can be used as the Thresh value. X,HighQ The value of, or, the above Thresh X,HighQ Replace with ThreshX,HighQfornes.
[0425] In another design approach, the Squal of high-priority inter-frequency / inter-system frequencies can be increased. The calculation process for increasing Squal can be found in the section above and will not be repeated here.
[0426] In another scenario, when threshServingLowQ is not configured, if the time spent in the current serving cell is greater than time 2, and the Srxlev of the high-priority inter-frequency / inter-system frequency is greater than the reselection high-amplitude threshold Thresh... X,HighP If the duration of a high-priority inter-frequency / inter-system frequency is greater than the time interval 2, then that high-priority inter-frequency / inter-system frequency can be used as a candidate cell.
[0427] To relax cell reselection evaluation, in one design, the terminal can shorten the time interval by 2. In another design, the terminal can shorten the time interval by 2. In yet another design, the terminal can lower the high-amplitude reselection threshold. In yet another design, the terminal can increase the signal amplitude of high-priority inter-frequency / inter-system frequencies. For details, please refer to the above description.
[0428] Furthermore, the process by which the terminal performs cell reselection evaluation using the first and second parameters in this situation can refer to the terminal's initiation measurement method described above. For example, if the NES terminal has been camped in the current serving cell for more than 2A, and the signal amplitude of the high-priority inter-frequency / inter-system frequency is greater than Thresh, then... X, HighPfornes lasts longer than Treselection RATfornes Then, the high-priority inter-frequency / inter-system frequency can be used as a candidate cell. ThreshX,HighPfornes represents the reselection high amplitude threshold 1 (i.e., the reduced reselection high amplitude threshold) in the first parameter, Treselection RATfornes This indicates a time interval of 2. ThreshX,HighPfornes can be replaced with Thresh. X,HighP However, Thresh X,HighP The value is 1, which represents the high-amplitude reselection threshold. Similarly, Treselection... RATfornes Too.
[0429] 3) For the serving cell of the terminal, neighboring cells include low-priority inter-frequency / inter-system frequency cells. Based on the above, in one scenario, when threshServingLowQ is configured, if the dwell time in the current serving cell is greater than time 3, and the Squal of the low-priority inter-frequency / inter-system frequency cell is greater than the reselection low-intensity threshold Thresh... X,LowQ If the Squal of the current serving cell is less than the service low intensity threshold ThreshServing,LowQ and the duration of the low-priority inter-frequency / inter-system frequency cell is greater than the time interval 3, the low-priority inter-frequency / inter-system frequency cell can be used as a candidate cell.
[0430] Therefore, to relax cell reselection evaluation, one design approach can shorten the time interval by 3. Another design approach can shorten the time interval by 3. Yet another design approach can lower the low-intensity reselection threshold. Another design approach can increase the Squal of low-priority inter-frequency / inter-system frequencies. Another design approach can increase the low-intensity service threshold. Yet another design approach can decrease the Squal of the currently serving cell.
[0431] For the specific implementation process, please refer to the description of the possible design methods introduced above. Since the principle is the same as the implementation process of the possible design methods introduced above, it will not be repeated here.
[0432] Additionally, the process by which the terminal performs cell reselection evaluation using the first and second parameters in this situation can refer to the terminal's initiation measurement or other methods described above. For example, if the NES terminal has been camped in the current serving cell for more than time 3A, and the Squal of the low-priority inter-frequency / inter-system frequency cell is greater than the reselection low-intensity threshold ThreshX,LowQfornes, and the Squal of the current serving cell is less than the service low-intensity threshold Thresh... Serving, LowQfornes lasts longer than Treselection RATfornes The low-priority inter-frequency / inter-system frequency cell can be used as a candidate cell.
[0433] In another scenario, when threshServingLowQ is not configured, if the time spent in the current serving cell exceeds time 4, and the Srxlev of the low-priority inter-frequency / inter-system frequency cell is greater than the reselection low-amplitude threshold Thresh... X,LowP If the Srxlev of the current serving cell is less than the service low amplitude threshold ThreshServing,LowP and the duration of the low-priority inter-frequency / inter-system frequency is greater than the time interval 4, the low-priority inter-frequency / inter-system frequency can be used as a candidate cell.
[0434] Therefore, to relax cell reselection evaluation, one design approach can shorten the time by 4. Another design approach can shorten the time interval by 4. Yet another design approach can lower the reselection low-amplitude threshold. Another design approach can raise the serving low-amplitude threshold. Another design approach can increase the Srxlev of low-priority inter-frequency / inter-system frequency cells. In yet another design approach, the serving cell can also lower the Srxlev of the current serving cell. For specific implementation details, please refer to the descriptions of the possible design approaches above.
[0435] Additionally, the implementation method for the terminal to perform the aforementioned low-priority inter-frequency / inter-system frequency cell reselection evaluation can refer to the terminal initiation measurement or other methods described above. For example, if the NES terminal's camping time in the current serving cell is greater than time 4A, and if the Srxlev of the low-priority inter-frequency / inter-system frequency cell is greater than the reselection low amplitude threshold ThreshX,LowPfornes, and the Srxlev of the current serving cell is less than the serving low amplitude threshold Thresh... Serving, LowPfornes lasts longer than Treselection RATfornes The low-priority inter-frequency / inter-system frequency can be used as a candidate cell.
[0436] It should be noted that the implementation methods described above can be independent of each other or combined with each other, and the parameters described in the implementation methods can also result in each other. In general, this application does not impose any restrictions on the number or type of cell reselection parameters to be adjusted.
[0437] It should be understood that the parameters in the formulas in this application embodiment represent parameters related to cell reselection parameters. This means that the values of the parameters in the formula are related to cell reselection parameters; that is, the values of the parameters in the formula are related to cell reselection parameters. For example, Q in formula seven above... rxlevmeasforNES The signal reception level value of the tested cell is represented by Q. rxlevmeasforNES The value is 1, which is the signal reception level value of the cell being tested.
[0438] The above describes how adjusting traditional cell reselection parameters to match those of the NES terminal can relax the NES terminal's cell reselection process, allowing it to reselect to an NES cell even when not at the edge of the current serving cell. Alternatively, the cell reselection process can also be relaxed by adjusting the cell reselection procedure. The following section will detail how to adjust the cell reselection procedure.
[0439] The cell reselection process for an NES terminal can include initiating measurement, selecting a cell based on cell reselection criteria, and performing cell reselection. In other words, when an NES terminal determines that neighboring cells include NES cells, it does not need to determine whether to initiate measurement based on condition 1; instead, it can directly initiate measurement. For example, if the neighboring cells of the currently serving cell include co-frequency cells, and the NES terminal learns that these co-frequency cells include NES cells, the NES terminal directly initiates co-frequency measurement, thereby relaxing co-frequency measurement and enabling the NES terminal to directly select a cell based on cell reselection criteria, thus increasing the likelihood of reselecting to an NES cell.
[0440] The neighboring cells of the current serving cell include inter-frequency / inter-system frequencies with low or equal priority. When the NES terminal learns that the inter-frequency / inter-system frequency cells with low or equal priority include NES cells, the NES terminal directly initiates inter-frequency / inter-system frequency measurement with low or equal priority, thereby relaxing inter-frequency measurement. This allows the NES terminal to directly select a cell based on the cell reselection criteria, thereby increasing the probability of reselecting to an NES cell.
[0441] In summary, regardless of whether the neighboring cell is a cell of the same frequency, a high-priority cell, a low-priority cell, or a cell of equal priority from a different frequency / system, as long as the neighboring cell is an NES cell, the NES terminal can directly start the measurement. Thus, when the NES terminal meets the cell reselection criteria, it can directly perform cell reselection, thereby enabling the NES terminal to reselect to an NES cell.
[0442] Optionally, the above measurement can be a periodic measurement.
[0443] Understandably, traditional terminals still initiate measurement based on condition 1. In other words, the cell reselection process of traditional terminals still includes: initiating measurement based on condition 1, selecting a cell based on the cell reselection criteria, and performing cell reselection.
[0444] It should be noted that the cell reselection parameters and procedures for the NES terminal described above can be independent or combined. For example, the cell reselection parameters used by the NES terminal are traditional cell reselection parameters, while the cell reselection procedure used by the NES terminal is the cell reselection procedure corresponding to the NES terminal (such as directly initiating measurement).
[0445] For example, the cell reselection parameters used by the NES terminal are the cell reselection parameters corresponding to the NES terminal (such as the first parameter mentioned above), while the cell reselection process used by the NES terminal is the cell reselection process corresponding to the traditional terminal (such as needing to start measurement according to condition 1).
[0446] For example, the cell reselection parameters used by the NES terminal are the same as those used by the NES terminal, and the cell reselection process used by the NES terminal is the same as that used by the NES terminal.
[0447] In this embodiment of the application, for parameters (such as parameter A) used to trigger the start measurement and / or perform cell selection evaluation, if parameter A needs to be determined using multiple parameters (such as parameter B1 and parameter B2), and parameter A needs to be adjusted, parameters B1 and B2 can be increased if parameter A needs to be increased; or parameter B1 can be increased without changing parameter B2; or parameter B2 can be increased without changing parameter B1. Of course, other methods can also be used to change parameters B1 and B2, as long as parameter A is increased. For example, the above R... n =Q meas,n -Qoffset-Qoffset temp, By increasing Q meas,n without changing Qoffset. temp In the case of increasing R n .
[0448] In the embodiments of this application, the bias value can be a value greater than 0.
[0449] In some embodiments, the cell reselection parameters (such as the first and second parameters mentioned above) obtained by the NES terminal may be sent by the network device of the terminal's serving cell. The process of sending cell reselection parameters is described below with reference to Figure 5. As shown in Figure 5, the process includes:
[0450] S301, The network device sends the first parameter, or the network device sends the first parameter and the second parameter.
[0451] S302, the NES terminal receives the first parameter, or the NES terminal receives the first parameter and the second parameter.
[0452] In this embodiment of the application, the network device can send a first parameter, and correspondingly, the NES terminal can receive the first parameter so that the NES terminal can use the first parameter to reselect to the NES cell.
[0453] Alternatively, the network device can send a first parameter and a second parameter. Correspondingly, the NES terminal can receive the first parameter and the second parameter, so that the NES terminal can use either the first parameter or the second parameter as needed. For example, if the neighboring cell includes an NES cell, the terminal can reselect to the NES cell using the first parameter.
