[0230] In some embodiments, for terrestrial networks (TN) and / or NTNs, there is a set of rules or criteria for UE cell selection and / or reselection.
[0231] In some embodiments, the above criteria include cell ranking criteria (R criteria), wherein the cell ranking criteria Rs of the serving cell and the cell ranking criteria Rn of the neighboring cells are defined as follows:
[0232] Rs = Qmeas,s + Qhyst - Qoffset temp ;
[0233] Rn = Qmeas,n - Qoffset - Qoffset temp ;
[0234] Where Qmeas represents the RSRP measurement value used for cell reselection; Qoffset temp It can be a temporary offset applied to the cell according to the standard TS38.331[3] specification;
[0235] For Qoffset:
[0236] In scenarios with the same frequency, if Qoffset s,n If valid, it equals Qoffset. s,n Otherwise, it is zero.
[0237] In scenarios with different frequencies, if Qoffset s,n If valid, it equals Qoffset. s,n Add Qoffset frequency Otherwise, it equals Qoffset. frequency .
[0238] In some embodiments, network devices can configure Qhyst and Qoffset to adjust cell priorities.
[0239] In some embodiments, the network device can also adjust Qoffset. temp Configure the settings to temporarily lower or raise the priority of the cell.
[0240] In some embodiments, the UE first determines the priority of each frequency according to the frequency priority configured in the network. For frequencies with the same frequency or different frequencies with the same priority, the R criterion described above is used to determine the R value of each cell, and the UE accesses the target cell according to the order of the R values.
[0241] In some embodiments, the measurement relaxation criteria for user equipment (UE) not located at the cell edge will be satisfied when the following conditions are met:
[0242] Srxlev>S SearchThresholdP ;and,
[0243] Squal>S SearchThresholdQ If S SearchThresholdQ Configured.
[0244] In some embodiments, Srxlev is the current received level value of the serving cell (in dB), and Squal is the current signal quality value of the serving cell (in dB).
[0245] In some embodiments, the measurement relaxation criteria for low-capability user equipment (Redcap UE, eRedcap UE) not located at the cell edge will be satisfied when the following conditions are met:
[0246] Srxlev>S SearchThresholdP2 ;and,
[0247] Squal>S SearchThresholdQ2 If S SearchThresholdQ2 Configured.
[0248] In some embodiments, Srxlev is the current received level value of the serving cell (in dB), and Squal is the current signal quality value of the serving cell (in dB).
[0249] In some embodiments, the cell selected by the terminal during cell reselection or cell reselection needs to satisfy the S criterion, which is as follows: Srxlev>0 AND Squal>0;
[0250] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp ;
[0251] Squal = Q qualmeas –(Q qualmin +Q qualminoffset –Qoffset temp .
[0252] Where Srxlev represents the signal reception level, Squal represents the signal reception quality, and Q... rxlevmeas Q represents the measured reception level for the serving cell. qualmeas Q represents the measurement reception quality for the serving cell. rxlevmin Q represents the minimum signal reception level requirement. qualmin P represents the minimum signal reception quality requirement. compensation Indicates the power compensation value;
[0253] Qoffset temp Indicates a temporary offset, Q rxlevminoffset Q represents the offset value of the minimum signal reception level requirement. qualminoffset This represents the offset value indicating the minimum required signal reception quality.
[0254] In some embodiments, when performing cell reselection, the terminal device needs to determine when to measure neighboring cells, or when to measure frequencies, or when to measure the frequencies of neighboring cells. This can typically be determined in the following ways:
[0255] If the serving cell satisfies Srxlev>S IntraSearchP and Squal>S IntraSearchQ The UE may not perform in-frequency measurements; otherwise, the UE should perform in-frequency measurements.
[0256] If the serving cell satisfies Srxlev>S nonIntraSearchP and Squal>S nonIntraSearchQ The UE may not perform inter-frequency measurements or cross-RAT measurements; otherwise, the UE should perform inter-frequency measurements or cross-RAT measurements.
[0257] Where Srxlev represents the signal reception level, Squal represents the signal reception quality, and S IntraSearchP S is a threshold for the signal reception level used to determine whether to trigger in-frequency measurements. IntraSearchQ S is a signal reception quality threshold used to determine whether to trigger in-frequency measurements. nonIntraSearchP S is a threshold used to determine whether to trigger inter-frequency measurements or cross-radio access technology RAT measurements for signal reception level. nonIntraSearchQ This is a threshold for signal reception quality used to determine whether to trigger inter-frequency measurements or cross-RAT measurements.
[0258] In some embodiments, the SSB period, offset, and duration configuration corresponding to the redirected SSB frequency are based on the time reference of the primary cell (PCell). If this field is not configured, the UE will use an SMTC configured in the measurement object NR (measObjectNR) that has the same SSB frequency and subcarrier spacing.
[0259] In some embodiments, non-terrestrial networks provide radio resources via satellite (or drones) instead of terrestrial base stations. In NTNs, downlink coverage enhancement (DL CE) can be supported, including, for example, extended SSB periods; Physical Downlink Control Channel (PDCCH) coverage enhancement; and Physical Downlink Shared Channel (PDSCH) coverage enhancement, such as Msg4 PDSCH repetition. Therefore, for the same cell, the actual cell coverage differs between UEs supporting DL CE and those not supporting DL CE.
[0260] The above embodiments have the following problems:
[0261] Cell reselection R criterion issue: The coverage provided by cells supporting DL CE is better for UEs that support DL CE than that of CEs that do not support DL CE. Therefore, UEs that support DL CE should preferentially reselect to cells that support DL CE. However, the existing R criterion calculation process does not reflect the advantage of cells that support DL CE can provide better coverage.
[0262] Problems with measurement relaxation criteria: The UE can determine whether it is at the cell edge based on the received signal strength and / or quality. If the UE is not at the cell edge, measurement relaxation can be performed. For cells that support DL CE, if the same threshold value is configured for UEs that support DL CE and UEs that do not support DL CE, then the threshold value for UEs that support DL CE to evaluate whether they are at the cell edge is too strict.
[0263] The issue with SMTCs: Currently, only one SMTC can be configured for redirection to NR NTN. However, considering that NR NTN already supports configuring up to four SMTCs for a single frequency, different NR NTN cells may require different SMTC configurations.
[0264] Frequency measurement issue: UEs that support DLCE have better downlink coverage than UEs that do not support DLCE. Therefore, UEs that support DLCE can operate at lower signal reception quality and / or signal reception level than UEs that do not support DLCE. Therefore, the threshold values for measuring received signal quality and / or signal reception level for the frequency that triggers cell reselection for UEs should be set differently for UEs that support DLCE and UEs that do not support DLCE.
[0265] Regarding the S-criterion for cell selection / reselection, UEs supporting DLCE have better downlink coverage than UEs that do not support DLCE. Therefore, compared to UEs that do not support DLCE, UEs supporting DLCE can operate at lower signal reception quality and / or signal reception level. Thus, the parameters of the calculation formula for the S-criterion for signal reception quality and / or signal reception level can be set differently for UEs supporting DLCE and UEs that do not support DLCE.
[0266] In some embodiments, the cell reselection R criterion can be configured so that cells supporting DL CE can be configured with specific parameters applied to the calculation of R values for UEs supporting DL CE, so that UEs can preferentially reselect to cells supporting DL CE.
[0267] In some embodiments, the measurement relaxation criteria can support cells that support DL CE to be configured with specific parameters that determine whether a UE supporting DL CE is not at the cell edge, so that the UE can further relax the measurement.
[0268] In some embodiments, multiple SMTCs are configured for redirection to NR NTN.
[0269] Figure 2 This is an interactive schematic diagram illustrating a communication method according to an embodiment of this disclosure. For example... Figure 2 As shown, the embodiments of this disclosure relate to a communication method, which includes:
[0270] Step S2101: The network device sends the first information to the terminal.
[0271] In some embodiments, the network device sends the first information to a first type of terminal, but is not limited thereto; the network device may also send the first information to a third type of terminal. Optionally, the network device broadcasts the first information.
[0272] In some embodiments, the network device may be the access network device of the serving cell of the terminal. Optionally, the network device may send first information to each terminal it serves.
[0273] In some embodiments, the network device sends the first information to a terminal in an RRC inactive state. Optionally, the network device may also send the first information to a terminal in an RRC active state or an RRC idle state.
[0274] Optionally, the network device sends the first message via an RRC release message.
[0275] In some embodiments, the first information is used to indicate at least one of the following:
[0276] The first parameter is used by the first type of terminal to sort the first cell during cell reselection;
[0277] The second parameter is used by the first type of terminal to determine whether a measurement relaxation is required.
[0278] The third parameter is used by the first type of terminal to determine the measurement frequency during cell reselection.
[0279] The fourth parameter is used by the first type of terminal to determine the S criterion during cell selection or cell reselection.
[0280] At least one first synchronization signal block measurement time configuration SMTC, the first SMTC being the SMTC applied when the terminal is redirected to a non-terrestrial network NTN cell.
[0281] In some embodiments, the first parameter, second parameter, third parameter, and fourth parameter described above may be used only for the first type of terminal. When the terminal receiving the first information is not the first type of terminal, the first parameter, second parameter, third parameter, and fourth parameter may be ignored, or cell sorting, measurement relaxation assessment, measurement frequency determination, and S criterion determination may not be performed based on the first parameter, second parameter, third parameter, and fourth parameter indicated by the first information.
[0282] In some embodiments, the first information may include only the first parameter, the second parameter, the third parameter, the fourth parameter, and one or some or all of the first SMTC. For example, the first information may include only the first parameter. In this case, the first type of terminal may sort the first cell during cell reselection based solely on the indication of the first information, without needing to perform other processes based on the second, third, and fourth parameters.
[0283] In some embodiments, the first SMTC described above can be applied to any terminal. For example, after a terminal receives first information including the first SMTC, it determines to be redirected to an NTN cell. Then, regardless of whether the terminal is a first type terminal or a third type terminal, it can perform measurements based on the first SMTC.
[0284] In some embodiments, the network device may configure one or more first SMTCs for each satellite orbit type. For example, multiple first SMTCs may be configured for geostationary orbit types and multiple first SMTCs may be configured for low Earth orbit types. If the terminal determines that it has been redirected to an NTN cell of the geostationary orbit type, it can perform measurements based on the multiple first SMTCs corresponding to the geostationary orbit type. If the terminal determines that it has been redirected to an NTN cell of the low Earth orbit type, it can perform measurements based on the multiple first SMTCs corresponding to the low Earth orbit type.
[0285] In some embodiments, the network device may configure one or more first SMTCs for a frequency, such as the frequency used by an NTN cell. Optionally, the network device may configure one or more first SMTCs for each frequency used by an NTN cell.
[0286] In some embodiments, the network device may configure the corresponding period, offset and / or PCI for each first SMTC, or it may configure multiple first SMTCs to reuse the same period.
[0287] In some embodiments, the first type of terminal is a terminal device that supports downlink coverage enhancement. Optionally, the first type of terminal supports at least one of the following: extended SSB period; PDCCH coverage enhancement; PDSCH coverage enhancement; MSG2 coverage enhancement; MSG4 coverage enhancement; MGS4 coverage enhancement.
[0288] In some embodiments, the third type of terminal is a device that does not support downlink coverage enhancement. Optionally, the third type of terminal does not support at least one of the following: extended SSB period; PDCCH coverage enhancement; PDSCH coverage enhancement. Optionally, the third type of terminal is a terminal device other than the first type of terminal.
[0289] For example, if a first type of terminal is defined as a terminal device that supports both PDCCH coverage enhancement and PDSCH coverage enhancement, then a third type of terminal can be defined as a terminal device that does not support PDCCH coverage enhancement and / or does not support PDSCH coverage enhancement.
[0290] In some embodiments, while configuring the first, second, third, and fourth parameters for a first type of terminal, the network also configures parameters corresponding to the first, second, third, and fourth parameters for a third type of terminal or a terminal that does not support DLCE.
[0291] In some embodiments, the first parameter includes at least one of the following:
[0292] The first temporary offset value is used by the first type of terminal to calculate the sorting value of the first cell;
[0293] The first lag value is used by the first type of terminal to calculate the ranking value of the serving cell of the first type of terminal in the first cell;
[0294] The first offset value is used by the first type of terminal to calculate the sorting value of the neighboring cells of the first type of terminal in the first cell.
[0295] In some embodiments, the first parameter may be configured for each cell. Optionally, the cell associated with the first parameter may refer to the cell for which the network device has configured the first parameter. Optionally, the first cell may refer to the cell for which the first parameter has been configured.
[0296] In some embodiments, the first parameter configured by the network device for each first cell may be the same or different, and this disclosure does not limit this.
[0297] In some embodiments, the network device can configure a first parameter for the serving cell and neighboring cells of the terminal that support downlink coverage enhancement. Optionally, the network device may not configure the first parameter for the serving cell and neighboring cells of the terminal that do not support downlink coverage enhancement, or the network device may configure other parameters for the cells that do not support downlink coverage enhancement, so that the first type of terminal can use the configured other parameters to sort these cells.
[0298] For example, a terminal's serving cell is cell1, and its neighboring cells include cell2, cell3, cell4, and cell5. Cell1, cell2, and cell3 support downlink coverage enhancement, while cell4 and cell5 do not. In this case, cell1 can configure a first parameter (such as configuring a first temporary offset) for cells1, 2, and 3, but not configure a first parameter for cells4 and 5 (such as configuring a second temporary offset, or instructing the terminal to use a default temporary offset for cells4 and 5). If the terminal is a type 1 terminal, the sorting values for cells1, 2, and 3 can be determined based on the first temporary offset, and the sorting values for cells4 and 5 can be determined based on the second temporary offset or the default temporary offset. Further sorting is then performed based on the sorting values of each cell.
[0299] In some embodiments, the second parameter includes at least one of the following:
[0300] The fifth threshold is a signal reception level threshold used to determine whether to trigger a measurement relaxation.
[0301] The sixth threshold is a signal quality threshold used to determine whether to trigger a measurement of relaxation.
[0302] The seventh threshold is a signal reception level threshold used by the second type of terminal to determine whether to trigger measurement relaxation;
[0303] The eighth threshold, the second type of terminal determines whether to trigger a measurement relaxation of the signal reception quality threshold;
[0304] The second type of terminal is a terminal with reduced capabilities from the first type of terminal.
[0305] It is understandable that the first type of terminal may include terminals with reduced capabilities, i.e., second type terminals, such as RedcapUE or eRedcapUE, or terminals without reduced capabilities, such as terminals other than the second type of terminal. For example, a terminal may be a reduced-capability terminal that supports downlink coverage enhancement. The downlink reception capabilities of the reduced-capability terminal and the non-reduced-capability terminal may differ.
[0306] In some embodiments, the third parameter includes at least one of the following:
[0307] The first threshold is a signal reception level threshold used to determine whether to trigger in-frequency measurements.
[0308] The second threshold is a signal reception quality threshold used to determine whether to trigger in-frequency measurements.
[0309] The third threshold is a signal reception level threshold used to determine whether to trigger inter-frequency measurements or cross-radio access technology RAT measurements.
[0310] The fourth threshold is a signal reception quality threshold used to determine whether to trigger inter-frequency measurements or cross-RAT measurements.
[0311] In some embodiments, the fourth parameter includes at least one of the following:
[0312] The second offset value is the offset value required for the minimum signal reception level;
[0313] The third offset value is the offset value for the minimum signal reception quality requirement;
[0314] The second temporary offset value is the offset value of the cell's signal reception level and / or signal reception quality.
[0315] In some embodiments, the fourth parameter may be configured by the network device for a cell that supports downlink enhancement (such as the first cell). Optionally, the first type of terminal may determine whether each cell supporting downlink enhancement meets the S standard based on the fourth parameter, such as determining the signal reception level and / or signal reception quality of each first cell, and determining whether the signal reception level and / or signal reception quality is greater than zero.
[0316] In some embodiments, one or more of the second and third parameters described above may be configured by the network device for the serving cell of the terminal. Optionally, the first type of terminal may determine whether to trigger measurement relaxation and / or when to perform frequency measurements during cell reselection based on the signal reception level and / or signal reception quality of the serving cell, as well as the second and / or third parameters.
[0317] In some embodiments, the serving cell of the terminal may be a cell that supports downlink enhancement (such as the first cell) or a cell that does not support downlink enhancement. This disclosure does not limit the specific cell in question.
[0318] In some embodiments, the terminal receives first information. Optionally, the terminal determines that it has received the first information and performs at least one of steps S2102 to S2106.
[0319] Optionally, if the first information includes the fourth parameter, the first type of terminal may execute step S2102;
[0320] Optionally, if the first information includes the third parameter, the first type of terminal may execute step S2103;
[0321] Optionally, if the first information includes the second parameter, the first type of terminal may execute step S2104;
[0322] Optionally, if the first information includes the first parameter, the first type of terminal may execute step S2105;
[0323] Optionally, if the first information includes at least one first synchronization signal block measurement time configuration SMTC, the terminal may execute step S2106, wherein the terminal may be a first type terminal and / or other terminals;
[0324] Optionally, if the first information includes the first parameter and the second parameter, the first type of terminal can execute steps S2105 and S2104. The two can be executed in any order or are not limited here, and can be set by the user based on their needs.
