[0035] The cell reselection method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0036] As shown in Figure 2, this application embodiment provides a cell reselection method 200, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal, and the method includes the following steps.

[0037] S202: The terminal performs signal measurements on the currently serving cell and one or more neighboring cells of the serving cell.

[0038] In the Radio Resource Control (RRC) idle or inactive state, the terminal can perform cell selection and cell reselection to find a suitable cell and camp on that cell (i.e., the serving cell). While camping on the serving cell, the terminal can continuously measure the signal quality of the current serving cell and neighboring cells in order to reselect to a cell with higher priority or better channel quality.

[0039] In another example of this embodiment, the terminal performs signal measurement on the currently serving cell, which is a single-carrier cell. If the serving cell does not satisfy Srxlev>S IntraSearchP Or does not satisfy Squal>S IntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells; where Srxlev is the standard power value measured by S, S IntraSearchP This is the starting threshold for the power standard measurement at the same frequency. Squal is the quality standard value of the S-standard measurement. IntraSearchQ This is the threshold for initiating the same-frequency measurement quality standard; for the definition of same-frequency measurement, please refer to the description of the following embodiments.

[0040] In another example of this embodiment, the terminal performs signal measurement on the currently serving cell, which is a single-carrier cell. If the serving cell does not satisfy Srxlev>S nonIntraSearchP Or does not satisfy Squal>S nonIntraSearchQ If the terminal performs equal-priority / low-priority inter-frequency measurement or inter-RAT measurement, then Srxlev is the standard power value of the S-standard measurement, and S... nonIntraSearchP This is the starting threshold for non-synchronous frequency power measurement standards. Squal is the quality standard value of the S-standard measurement. nonIntraSearchQ This is the threshold for initiating quality standards for non-synchronous frequency measurements; the definition of non-synchronous frequency measurements can be found in the following examples.

[0041] In this embodiment, for example, the terminal performs signal measurement on the currently serving cell, which is an SCMC. Then, the aforementioned "if the serving cell does not satisfy Srxlev>S" condition... IntraSearchP Or does not satisfy Squal>S IntraSearchQ "Then the terminal performs same-frequency measurement on neighboring cells" can be replaced with one of the following:

[0042] 1) If the anchor frequency cell of the serving cell does not satisfy Srxlev>S IntraSearchP Or does not satisfy Squal>S IntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells.

[0043] 2) If the paging frequency unit of the serving cell does not satisfy Srxlev>S IntraSearchP Or does not satisfy Squal>S IntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells.

[0044] 3) If the anchor frequency cell of the serving cell does not satisfy Srxlev>S IntraSearchP Or does not satisfy Squal>S IntraSearchQ Or, the paging frequency unit of the serving cell does not satisfy Srxlev>S IntraSearchP Or does not satisfy Squal>S IntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells.

[0045] Similarly, "if the serving cell does not satisfy Srxlev>S nonIntraSearchP Or does not satisfy Squal>S nonIntraSearchQ The phrase "the terminal performs equal / low-priority inter-frequency measurement or inter-RAT measurement" can be replaced with one of the following:

[0046] 1) If the anchor frequency cell of the serving cell does not satisfy Srxlev>S nonIntraSearchP Or does not satisfy Squal>S nonIntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells.

[0047] 2) If the paging frequency unit of the serving cell does not satisfy Srxlev>S nonIntraSearchP Or does not satisfy Squal>S nonIntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells.

[0048] 3) If the anchor frequency cell of the serving cell does not satisfy Srxlev>S nonIntraSearchP Or does not satisfy Squal>S nonIntraSearchQ Or, the paging frequency unit of the serving cell does not satisfy Srxlev>S nonIntraSearchP Or does not satisfy Squal>S nonIntraSearchQ Then the terminal performs co-frequency measurement on neighboring cells.

[0049] S204: Execute a cell reselection procedure based on the measurement results; wherein, one or more neighboring cells of the serving cell include a first neighboring cell, and the serving cell or the first neighboring cell includes at least two frequency elements.

[0050] The measurement results may include the measurement results of the serving cell and / or the measurement results of neighboring cells.

[0051] The cell reselection process may include cell reselection assessment and cell reselection based on cell reselection criteria. Further, cell reselection includes high-priority inter-frequency reselection, intra-frequency reselection, equal-priority inter-frequency reselection, low-priority inter-frequency reselection, or inter-Radio Access Technology (RAT) reselection. Cell reselection criteria include high-priority inter-frequency reselection criteria, intra-frequency reselection and equal-priority inter-frequency reselection criteria, low-priority inter-frequency reselection, or inter-Radio Access Technology reselection criteria.

[0052] It should be noted that S202 includes two sub-steps: serving cell measurement and neighboring cell measurement; while S204 includes serving cell and neighboring cell reselection assessment, and performs multiple sub-steps such as cell reselection based on measurement results and cell reselection criteria. This embodiment does not limit the order in which these sub-steps are performed.

[0053] The frequency unit in various embodiments of this application may include at least one of the following: carrier, carrier group, frequency band, frequency band group, bandwidth portion (BWP), and BWP group. In subsequent embodiments, a cell comprising at least two frequency units may also be referred to as a Single-cell Multiple-carrier (SCMC).

[0054] In this embodiment, the serving cell where the terminal is currently camped can be an SCMC, and the first neighboring cell of the serving cell can also be an SCMC; or, the serving cell where the terminal is currently camped can be a single-carrier cell, and the first neighboring cell of the serving cell can be an SCMC; or, the serving cell where the terminal is currently camped can be an SCMC, and the first neighboring cell of the serving cell can be a single-carrier cell.

[0055] The cell reselection method provided in this application involves a terminal performing signal measurements on the currently serving cell and one or more neighboring cells of the serving cell; and executing a cell reselection process based on the measurement results. The one or more neighboring cells of the serving cell include a first neighboring cell, and the serving cell or the first neighboring cell includes at least two frequency elements. In this application embodiment, the terminal can execute the cell reselection process in an SCMC scenario to reselect a cell with higher priority or better channel quality, thereby improving the communication performance of the terminal and network-side equipment.

[0056] In related technologies, a cell has only one carrier. Therefore, the measurement behavior of terminals in RRC idle or RRC inactive states regarding their currently serving cell is relatively simple. However, SCMC has multiple frequency units, and how to measure the serving cell is an unsolved technical problem. For example, should the measurement be performed on the anchor frequency unit of the SCMC serving cell, the paging frequency unit, or other frequency units? The following embodiments will introduce the measurement of SCMC serving cells, intra-frequency measurement, and inter-frequency measurement.

[0057] In some embodiments, the serving cell includes at least two frequency elements, for example, the serving cell is an SCMC, hereinafter referred to as the SCMC serving cell. The cell reselection procedure based on measurement results mentioned in S204 includes: evaluating the quality of the serving cell based on at least one of the following:

[0058] 1) The Reference Signal Receiving Power (RSRP) value of the anchor frequency unit in the serving cell. In this example, in S202, the terminal can perform signal measurement on the anchor frequency unit in the serving cell, and in S204, the terminal evaluates the quality of the serving cell based on the RSRP value of the anchor frequency unit, for example, determining whether to initiate neighbor cell measurement.

[0059] The anchor frequency unit in various embodiments of this application can be an anchor carrier, a main frequency unit, a basic frequency unit, etc.

[0060] 2) The Reference Signal Receiving Quality (RSRQ) value of the anchor frequency unit in the serving cell. In this example, in S202, the terminal can perform signal measurement on the anchor frequency unit in the serving cell, and in S204, the terminal evaluates the quality of the serving cell based on the RSRQ value of the anchor frequency unit, for example, determining whether to initiate neighbor cell measurement.

[0061] 3) The RSRP value of the paging frequency unit in the serving cell. In this example, in S202, the terminal can perform signal measurement on the paging frequency unit in the serving cell, and in S204, the terminal evaluates the quality of the serving cell based on the RSRP value of the paging frequency unit, for example, determining whether to initiate neighbor cell measurement.

[0062] The paging frequency unit in various embodiments of this application may be a paging carrier.

[0063] 4) The RSRQ value of the paging frequency unit in the serving cell. In this example, in S202, the terminal can perform signal measurement on the paging frequency unit in the serving cell, and in S204, the terminal evaluates the quality of the serving cell based on the RSRQ value of the paging frequency unit, for example, determining whether to initiate neighbor cell measurement.

[0064] As previously mentioned, the cell reselection process may include cell reselection assessment and cell reselection based on cell reselection criteria. In this embodiment, after assessing the quality of the serving cell, cell reselection can be performed based on cell reselection criteria.

[0065] In this embodiment, for example, while the terminal is camped on the SCMC, it performs signal measurements on the anchor frequency unit, evaluates the quality of the SCMC serving cell based on the RSRP and RSRQ values ​​of the anchor frequency unit, and determines whether to initiate neighbor cell measurements based on this.

[0066] In this embodiment, for example, while the terminal is camped on the SCMC, it performs signal measurements on the paging frequency unit, evaluates the quality of the SCMC serving cell based on the RSRP and RSRQ values ​​of the paging frequency unit, and determines whether to initiate neighbor cell measurements based on this.

[0067] In this embodiment, for example, while the terminal is camped on the SCMC, it performs signal measurements on the paging frequency unit. If the RSRP value of the paging frequency unit is lower than or equal to a first threshold, or the RSRQ value of the paging frequency unit is lower than or equal to a second threshold, the terminal performs signal measurements on the anchor frequency unit in the serving cell. Based on the RSRP and RSRQ values ​​of the anchor frequency unit, the quality of the SCMC serving cell is evaluated, and based on this, it is determined whether to initiate neighbor cell measurement. In most cases, the quality of the anchor frequency unit is better than that of the paging frequency unit. Therefore, when the quality of the paging frequency unit is better, the terminal does not need to measure the anchor frequency unit, which helps save terminal power.

[0068] The aforementioned first or second threshold can be agreed upon by the protocol or configured by the network-side equipment.

[0069] In this embodiment, for example, while the terminal is camped on the SCMC, it performs signal measurements on the anchor frequency unit and the paging frequency unit. Based on the RSRP and RSRQ values ​​of the anchor frequency unit and the paging frequency unit, it evaluates the quality of the SCMC serving cell and determines whether to initiate neighbor cell measurement. For example, if the RSRP and RSRQ values ​​of the anchor frequency unit meet the initiation threshold for neighbor cell measurement (e.g., a first initiation threshold) and the RSRP and RSRQ values ​​of the paging frequency unit meet the initiation threshold for neighbor cell measurement (e.g., a second initiation threshold; the first and second initiation thresholds may be the same or different), the terminal initiates neighbor cell measurement.

[0070] In this embodiment, for example, while the terminal is camped on the SCMC, it performs signal measurements on the paging frequency unit and determines the RSRP value of the anchor frequency unit in the serving cell based on a first offset and the RSRP value of the paging frequency unit; or, it determines the RSRQ value of the anchor frequency unit in the serving cell based on a second offset and the RSRQ value of the paging frequency unit; based on the RSRP and RSRQ values ​​of the anchor frequency unit, it evaluates the quality of the SCMC serving cell and determines whether to initiate neighbor cell measurement.

[0071] In this embodiment, the terminal performs signal measurement on the currently camped serving cell, including: the terminal performs signal measurement on the paging frequency unit in the serving cell to obtain the RSRP value or RSRQ value of the paging frequency unit; based on a first offset and the RSRP value of the paging frequency unit, the terminal determines the RSRP value of the anchor frequency unit in the serving cell; or, based on a second offset and the RSRQ value of the paging frequency unit, the terminal determines the RSRQ value of the anchor frequency unit in the serving cell.

[0072] The first or second offset mentioned above can be configured by the network-side device broadcast, or it can be calculated by a formula predefined in the protocol.

[0073] In some embodiments, the terminal performs signal measurement on the currently camped serving cell, including at least one of the following: 1) the terminal performs signal measurement on the anchor frequency unit in the serving cell to obtain the RSRP value or RSRQ value of the anchor frequency unit; 2) the terminal performs signal measurement on the paging frequency unit in the serving cell to obtain the RSRP value or RSRQ value of the paging frequency unit; if the RSRP value of the paging frequency unit is lower than or equal to a first threshold or the RSRQ value of the paging frequency unit is lower than or equal to a second threshold, the terminal performs signal measurement on the anchor frequency unit in the serving cell.

[0074] The above embodiments mention that the terminal performs signal measurement on the paging frequency unit in the serving cell. When the serving cell includes multiple paging frequency units, the terminal performs signal measurement on the paging frequency unit that it is listening to.

[0075] In the above embodiments, in the scheme for the terminal to determine whether to start neighbor cell measurement, the terminal can determine the S criterion parameter values ​​Srxlev and Squal of the anchor frequency unit or paging frequency unit, and compare the S criterion parameter values ​​with the same frequency measurement start threshold and the different frequency measurement (same / low priority different frequency measurement or different RAT measurement) start threshold respectively.

[0076] Optionally, the neighbor cell measurement initiation threshold can be at the cell level, meaning that the SCMC broadcast can be used for the neighbor cell measurement initiation threshold of all frequency units in the cell; the neighbor cell measurement initiation threshold can also be at the frequency unit level, for example, the neighbor cell measurement initiation threshold corresponding to the anchor frequency unit of the SCMC broadcast can be different from the neighbor cell measurement initiation threshold corresponding to the paging frequency unit, and this application embodiment does not impose any restrictions.

[0077] The above embodiments mainly introduce the technical solutions related to SCMC serving cell measurement and evaluation. The following will introduce the technical solutions for intra-frequency measurement and intra-frequency reselection, and inter-frequency measurement and inter-frequency reselection.

[0078] The following will introduce examples related to same-frequency measurement and same-frequency reselection, and different-frequency measurement and different-frequency reselection.

[0079] In some embodiments, the cell reselection process includes intra-frequency measurement and intra-frequency reselection, or inter-frequency measurement and inter-frequency reselection; wherein the intra-frequency measurement and intra-frequency reselection satisfy a first condition, and the inter-frequency measurement and inter-frequency reselection satisfy a condition other than the first condition, wherein the first condition includes one of the following:

[0080] 1) The frequency of the anchor frequency unit in the serving cell is the same as the frequency of the anchor frequency unit in the first neighboring cell. For example, the frequency of the anchor frequency unit of the SCMC serving cell is the same as the frequency of the anchor frequency unit of the SCMC neighboring cell.

[0081] 2) The frequency of the anchor frequency unit in the serving cell is the same as the frequency of the second neighboring cell, where the second neighboring cell is a single-frequency unit cell, and the neighboring cells of the serving cell include the second neighboring cell. For example, the frequency of the anchor frequency unit of the SCMC serving cell is the same as the frequency of the single-carrier neighboring cell.

[0082] 3) The frequency of the paging frequency unit in the serving cell is the same as the frequency of the anchor frequency unit in the first neighboring cell. For example, the frequency of the paging frequency unit in the SCMC serving cell is the same as the frequency of the anchor frequency unit in the SCMC neighboring cell.

[0083] 4) The frequency of the paging frequency unit in the serving cell is the same as the frequency of the second neighboring cell, where the second neighboring cell is a single-frequency unit cell, and the neighboring cells of the serving cell include the second neighboring cell. For example, the frequency of the paging frequency unit of the SCMC serving cell is the same as the frequency of the single-carrier neighboring cell.

[0084] 5) The frequency of the anchor frequency unit in the serving cell is the same as the frequency of the anchor frequency unit in the first neighboring cell, and the frequencies of other frequency units in the serving cell are the same as the frequencies of other frequency units in the first neighboring cell. For example, the anchor frequency units of the SCMC serving cell and the SCMC neighboring cell have the same frequency, and the other carrier frequencies of the SCMC serving cell and the SCMC neighboring cell are also completely identical. For example, the SCMC serving cell includes frequency units 1, 2, and 3, where frequency unit 1 is the anchor frequency unit; the SCMC neighboring cell includes frequency units 1, 2, and 3, where frequency unit 1 is the anchor frequency unit.

[0085] 6) The frequency of the paging frequency unit in the serving cell is the same as the frequency of the anchor frequency unit in the first neighboring cell, and the frequencies of other frequency units in the serving cell are the same as the frequencies of other frequency units in the first neighboring cell. For example, the frequency of the paging frequency unit of the SCMC serving cell is the same as the frequency of the anchor frequency unit of the SCMC neighboring cell, and the frequencies of other frequency units in the SCMC serving cell and the SCMC neighboring cell are also exactly the same.

[0086] 7) The frequencies of the frequency units in the serving cell are all the same as the frequencies of the frequency units in the first neighboring cell. For example, the frequencies of all frequency units in the SCMC serving cell and the SCMC neighboring cell are exactly the same. For example, the SCMC serving cell includes frequency units 1, 2, and 3, where frequency unit 1 is the anchor frequency unit; the SCMC neighboring cell includes frequency units 3, 2, and 1, where frequency unit 3 is the anchor frequency unit.

[0087] 8) The frequency of the frequency element in the serving cell is at least partially the same as the frequency of the frequency element in the first neighboring cell. For example, the SCMC serving cell and the SCMC neighboring cell have at least some frequency elements with the same frequency. For example, the SCMC serving cell includes frequency elements 1, 2, and 3, and the SCMC neighboring cell includes frequency elements 1, 2, and 4.

[0088] 9) The frequency of the serving cell is the same as the frequency of the anchor frequency unit in the first neighboring cell, and the serving cell is a single-frequency unit cell. For example, the frequency of the single-carrier cell currently camped by the terminal is the same as the frequency of the anchor frequency unit of the SCMC neighboring cell.

[0089] 10) The frequency of the serving cell is the same as the frequency of any one of the frequency units in the first neighboring cells, and the serving cell is a single-frequency unit cell. For example, the frequency of the single-carrier cell currently camped by the terminal is the same as the frequency of any one of the downlink frequency units in the SCMC neighboring cells.

[0090] In schemes 1) to 8) above, the terminal can reselect from the SCMC serving cell to a single-carrier cell or an SCMC neighbor cell; in schemes 9) and 10) above, the terminal is camped on a single-carrier cell and can reselect to an SCMC neighbor cell.

[0091] It is understandable that measurements that do not conform to the same-frequency measurement and same-frequency reselection definitions in 1) to 10) above, and belong to the same RAT, are all classified as different-frequency measurement and different-frequency reselection.

[0092] In some embodiments, the method further includes: the terminal determining a first frequency unit and at least one second frequency unit of the first neighboring cell, wherein the first frequency unit is an anchor frequency unit and the second frequency unit is a non-anchor frequency unit.

[0093] In this embodiment, the terminal can determine whether it is same-frequency measurement and same-frequency reselection or different-frequency measurement and different-frequency reselection based on the first frequency unit or the second frequency unit of the first neighboring cell.

[0094] For example, if the currently serving cell does not broadcast information about the second frequency unit of the first neighboring cell, it can be determined by default whether it is intra-frequency reselection or inter-frequency reselection based on the first frequency unit of the first neighboring cell; if the currently serving cell broadcasts information about the second frequency unit of the first neighboring cell, it can be determined by default whether it is intra-frequency reselection or inter-frequency reselection based on the first and second frequency units of the first neighboring cell, where the first neighboring cell can be an SCMC.

[0095] For example, the protocol stipulates that the terminal always determines intra-frequency reselection or inter-frequency reselection based on the first frequency unit of the first neighboring cell. If the currently serving cell broadcasts information about the second frequency unit of the first neighboring cell, this information is used by the terminal to measure the second frequency unit. Here, the first neighboring cell can be an SCMC (Signaled Cell Management Unit). This is because, after the terminal reselects to an SCMC neighboring cell, if it needs to listen for paging on a non-anchor frequency unit (e.g., a paging frequency unit calculated based on the UE ID), and then initiates measurement on that non-anchor frequency unit, the terminal may lose paging from network-side devices on the non-anchor frequency unit during the measurement period. Alternatively, after the terminal reselects to an SCMC neighboring cell, if it needs to initiate access on a non-anchor frequency unit, which is associated with a non-anchor downlink frequency unit, starting measurement at this point will increase access latency. Therefore, when the terminal is camped on the current serving cell and the neighboring cells of the current serving cell are SCMC neighboring cells, the system information of the current serving cell can provide information on the non-anchor frequency units of the SCMC neighboring cells, which can be used by the terminal to measure the non-anchor frequency units of the SCMC neighboring cells before reselecting to the SCMC neighboring cells.

[0096] In some embodiments, the terminal performing signal measurements on one or more neighboring cells of the serving cell includes: the terminal performing signal measurements on the first frequency unit and performing one of the following:

[0097] 1) The terminal performs signal measurement on the second frequency unit, which is a non-anchor downlink frequency unit.

[0098] For example, the terminal performs measurements on non-anchor downlink frequency cells by default. Optionally, the terminal evaluates cell reselection based on the measurement results of the first and second frequency cells.

[0099] When there are multiple second frequency units, the second frequency unit measured by the terminal can be all of the second frequency units, or it can be a single second frequency unit. When measuring a single second frequency unit, this single second frequency unit can be arbitrarily determined by the terminal, indicated by the network-side device, or determined based on preset rules.

[0100] 2) The terminal performs signal measurement on the second frequency unit within the first time interval.

[0101] For example, the terminal performs measurements on non-anchor downlink frequency units within a first time interval. Optionally, this first time interval is agreed upon by the protocol or configured by the network-side equipment.

[0102] 3) The terminal performs signal measurement on the second frequency unit based on the configuration or instructions of the network-side device.

[0103] In this example, the network-side device can configure or instruct the terminal whether to perform measurements on the second frequency unit. If there are multiple second frequency units, the network-side device can configure or instruct the terminal to measure all of the second frequency units, or to measure one or more of them.

[0104] 4) The terminal performs signal measurement on the second frequency unit based on the implementation.

[0105] In this example, the terminal can determine whether to perform signal measurements on the second frequency unit based on the implementation.

[0106] In this embodiment, the terminal determines a first frequency unit and at least one second frequency unit in the first neighboring cell, performs signal measurement on the first frequency unit, and determines whether signal measurement on the second frequency unit is required based on one of the above 1) to 4).

[0107] The above assumes that multiple downlink frequency units in an SCMC neighboring cell may have different frequencies, all of which will transmit reference signals, requiring the terminal to perform measurements. In a certain scenario, the frequencies of multiple downlink frequency units in an SCMC neighboring cell are close, potentially sharing a reference signal. In this case, the terminal only needs to measure the signal quality of the first frequency unit, optionally adding an offset, to obtain the signal quality of the second frequency unit. In this scenario, the cell's system information may not broadcast information about the multiple second frequency units of the SCMC neighboring cell, but only the frequency of the first frequency unit. When the terminal reselects to an SCMC neighboring cell, the signal quality of the second frequency unit can be derived from the first frequency unit and the offset broadcast by the cell. It should be noted that if the terminal camps on a non-anchor frequency unit to listen for paging, the terminal also needs to perform periodic measurements on that non-anchor frequency unit to maintain synchronization with the network-side equipment.

[0108] Therefore, in some embodiments, the method further includes: the terminal determining a third frequency unit and at least one fourth frequency unit of the serving cell, the third frequency unit being an anchor frequency unit and the fourth frequency unit being a non-anchor frequency unit; the terminal acquiring at least one first signal quality offset, the first signal quality offset being the offset of the signal quality of one of the at least one fourth frequency unit relative to the signal quality of the third frequency unit.

[0109] For example, if multiple downlink frequency units of an SCMC serving cell have similar frequencies and may share a reference signal, the terminal only needs to measure the signal quality of the third frequency unit and optionally add an offset to obtain the signal quality of the fourth frequency unit.

[0110] In some embodiments, the terminal obtaining at least one first signal quality offset includes: the terminal obtaining the at least one first signal quality offset from the system information of the serving cell. The first signal quality offset may include either the first offset or the second offset described in the preceding embodiments.

[0111] In some embodiments, the at least one first signal quality offset may also be obtained through a derivation method agreed upon in the protocol.

[0112] In some embodiments, when the terminal determines that a fifth frequency unit in the serving cell is listening for paging and the fifth frequency unit is not sending a reference signal, the method further includes: the terminal sending a first request, the first request being used to request the sending of a reference signal on the fifth frequency unit, the fifth frequency unit being referred to as a paging frequency unit.

[0113] Before the terminal sends the first request, the method further includes: the terminal determining whether the reference signal of the fifth frequency unit is being transmitted based on at least one of the following: system information of the serving cell; whether the reference signal is detected.

[0114] This embodiment is beneficial for energy saving of network-side equipment. For example, at certain times, based on the prediction algorithm of the network-side equipment, it is believed that some frequency units may not have any terminals camped. In this case, the network-side equipment may not send reference signals. If the terminal reselects to a certain frequency unit of the cell and finds that the reference signal of the paging frequency unit of the cell has not been sent, the terminal can request the network-side equipment to send the reference signal on that frequency unit.

[0115] The above embodiments mainly introduce the technical solutions for same-frequency measurement and same-frequency reselection, and different-frequency measurement and different-frequency reselection. The following will introduce how the terminal performs S-criteria verification on SCMC neighbor cells.

[0116] In cell reselection mechanisms in related technologies, the cell to be reselected by the terminal must meet the S criterion. In the SCMC scenario, when the terminal is camped on the current serving cell, one condition for reselecting to an SCMC neighbor cell is that the SCMC neighbor cell meets the S criterion. The following will introduce how the terminal performs the S criterion check on SCMC neighbor cells.

[0117] An SCMC neighboring cell may contain multiple uplink frequency units, each with different coverage capabilities and different maximum transmit power requirements for the terminal. When a terminal reselects to the SCMC neighboring cell to use a different uplink frequency unit, the network-side equipment may also have different minimum receive RSRP and minimum receive RSRQ requirements for the terminal to camp on that SCMC cell. The terminal can perform the S criterion test for that cell based solely on the minimum receive RSRP and minimum receive RSRQ requirements associated with the uplink frequency unit to be used in the SCMC neighboring cell.

[0118] In some embodiments, the cell reselection procedure based on measurement results includes: determining a sixth frequency element from at least two frequency elements of the first neighboring cell; and determining whether the first neighboring cell meets the S criterion based on the measurement results and the minimum reception requirement associated with the sixth frequency element. The first neighboring cell may be an SCMC neighboring cell; the minimum reception requirement may include a minimum received RSRP value requirement or a minimum received RSRQ value requirement.

[0119] Optionally, in at least two frequency units of the first neighboring cell, each uplink frequency unit is associated with a minimum reception requirement; alternatively, a baseline minimum reception requirement can be defined, and the minimum reception requirement associated with each uplink frequency unit can be defined as an offset relative to the baseline minimum reception requirement.

[0120] In this embodiment, for example, the terminal obtains at least two uplink frequency units of the first neighboring cell and the minimum reception requirement associated with each uplink frequency unit; the terminal determines a sixth frequency unit from the at least two uplink carriers and calculates the S-criteria of the first neighboring cell based on the minimum reception requirement associated with the sixth frequency unit.

[0121] In this embodiment, the terminal determines at least two uplink frequency units of the first neighboring cell, including the frequency point and bandwidth of each uplink frequency unit. The frequency point and / or bandwidth of the at least two uplink frequency units of the first neighboring cell can be predefined based on the protocol or obtained by the terminal from system information messages. For example, in the predefined method, the terminal can first learn from the system information message that there is an SCMC neighboring cell (e.g., the network side broadcast will indicate whether the cell type of the neighboring cell is SCMC or non-SCMC), and then determine it according to the carrier bandwidth of the uplink frequency unit of the SCMC as specified in the protocol. As another example, in the system information message configuration method, the system information block x (SIBx) of the currently camped serving cell will indicate the frequency point and bandwidth of each uplink frequency unit of the SCMC neighboring cell.

[0122] In some embodiments, the sixth frequency unit satisfies at least one of the following:

[0123] 1) is the uplink frequency unit supported by the terminal.

[0124] The uplink frequency unit supported by the terminal includes at least one of the following: the terminal supports the frequency of the uplink frequency unit; the bandwidth capability of the terminal meets the bandwidth requirements of the uplink frequency unit. Further, the bandwidth requirement of the uplink frequency unit is that the uplink bandwidth supported by the terminal is not greater than the bandwidth of the uplink frequency unit, and optionally, it is not less than the initial uplink bandwidth of the uplink frequency unit.

[0125] 2) is the uplink frequency unit that the terminal is interested in.

[0126] The uplink frequency unit that the terminal is interested in can be a frequency unit that the terminal determines itself based on its needs for power saving, coverage, and speed.

[0127] 3) is an uplink frequency unit that matches the service requirements of the terminal.

[0128] The uplink frequency unit that matches the terminal's service requirements can be a portion of the frequency units in the SCMC neighboring cell used to carry specific services, such as Multicast Broadcast Service (MBS) and Sidelink (SL). The network-side equipment needs to configure the service information carried by each uplink frequency unit in the SCMC neighboring cell in the system information. The terminal determines which uplink frequency unit in the SCMC neighboring cell is associated with the minimum reception requirement based on the current service requirements, and then calculates the S criterion of the SCMC neighboring cell.

[0129] In some embodiments, determining the sixth frequency unit from at least two frequency units of the first neighboring cell includes: determining the sixth frequency unit from at least two frequency units of the first neighboring cell based on at least one of the following:

[0130] 1) Terminal implementation, for example, based on the terminal implementation, one frequency unit is selected from at least two frequency units of the first neighboring cell as the sixth frequency unit.

[0131] 2) The coverage range of the at least two frequency units, for example, the terminal selects the frequency unit with the farthest coverage as the sixth frequency unit. Optionally, the frequency unit with the farthest coverage can be determined by rules agreed upon in the protocol, or explicitly indicated by the network-side device.

[0132] 3) The minimum reception requirements associated with each of the at least two frequency units, for example, selecting the uplink frequency unit with the lowest associated minimum reception requirement as the sixth frequency unit. For example, among the minimum reception requirements associated with each of the at least two frequency units, the sixth frequency unit has the lowest minimum reception RSRP value requirement or the lowest reception RSRQ value requirement associated with it.

[0133] 4) The frequencies of the at least two frequency units, for example, selecting the frequency unit with the lowest frequency as the sixth frequency unit.

[0134] 5) The priority of the at least two frequency units, for example, selecting the frequency unit with the highest priority as the sixth frequency unit. The priority of the at least two frequency units can be configured by the network-side device.

[0135] 6) The sorting of the at least two frequency units in the configuration information, for example, selecting the frequency unit with the highest or lowest sorting as the sixth frequency unit.

[0136] This configuration information is used to configure SCMC neighbor cells. The following describes the configuration methods for SCMC neighbor cells. In related technologies, for cell reselection, network-side devices first configure the frequency of neighbor cells in the system information, and then configure the list of neighbor cells at that frequency. Therefore, in the SCMC scenario, the configuration methods for SCMC neighbor cells can be as follows:

[0137] 1) The network-side equipment configures the SCMC neighbor cell list separately in the system information, and configures the downlink frequency units and uplink frequency units included in each SCMC neighbor cell. Similarly, the minimum reception requirement information associated with each uplink frequency unit will be configured under the corresponding configuration of the SCMC neighbor cell.

[0138] 2) The network-side device first configures the neighboring cell frequency in the system information, and then configures the SCMC neighboring cells and non-SCMC neighboring cells on that frequency. The anchor frequency unit of the SCMC neighboring cell is on that frequency. For each SCMC neighboring cell, the network-side device additionally configures information on multiple non-anchor frequency units. In this configuration method, the minimum reception requirement information associated with each uplink frequency unit is configured under the configuration corresponding to the SCMC neighboring cell, which can be considered as per UL carrier per SCMC neighboring cell. Alternatively, the network-side device will additionally configure an uplink frequency unit list and the minimum reception requirement (which can be considered as a frequency level requirement) associated with each uplink frequency unit. This list is not limited to a specific cell. In addition, the network-side device can also configure the offset of the minimum reception requirement for each SCMC neighboring cell (optional). The terminal calculates the S-criteria for the SCMC neighboring cell based on the minimum reception requirements of the frequency levels of the uplink frequency units included in the SCMC neighboring cell and the minimum reception requirement offset of the SCMC.

[0139] In some embodiments, the method further includes: the terminal obtaining at least one of the following from the system information of the serving cell:

[0140] 1) The at least two frequency units.

[0141] 2) The minimum reception requirement associated with each of the at least two frequency units.

[0142] 3) Service information associated with each of the at least two frequency units.

[0143] 4) The priority of each of the at least two frequency units.

[0144] 5) The coverage area associated with each of the at least two frequency units.

[0145] In some embodiments, the cell reselection process based on measurement results includes at least one of the following:

[0146] 1) During cell reselection evaluation, based on the measurement results and the system information of the serving cell, if the anchor frequency unit of the first neighboring cell satisfies the S criterion, the cell is reselected to the first neighboring cell.

[0147] 2) During cell reselection evaluation, based on the measurement results and the system information of the serving cell, if the anchor frequency unit of the first neighboring cell satisfies the S criterion and is the highest-ranked or best neighboring cell in the cell reselection, the paging frequency unit in the first neighboring cell is determined based on the system information of the first neighboring cell. If both the anchor frequency unit and the paging frequency unit in the first neighboring cell satisfy the S criterion, the cell is reselected to the first neighboring cell.

[0148] In this embodiment, the neighboring cell ranked highest in cell reselection can be the neighboring cell ranked highest in the R criterion in intra-frequency reselection or intra-frequency reselection with the same priority; the best neighboring cell can be a neighboring cell found based on the cell reselection criterion of absolute frequency priority (specifically, it can be a neighboring cell that meets the cell reselection criterion of absolute frequency priority. If there are multiple such neighboring cells, then the R criterion is used in intra-frequency reselection or intra-frequency reselection with the same priority for these multiple cells, and the neighboring cell ranked highest is the best neighboring cell).

[0149] This embodiment is designed based on the second assumption described below.

[0150] There are two assumptions for a terminal to camp on an SCMC: The first assumption is that one condition for a terminal to camp on an SCMC is that the measured RSRP and RSRQ values ​​of the anchor downlink frequency unit of that SCMC conform to the S criterion. Further, if the SCMC includes multiple uplink frequency units covering different areas, then the measured RSRP and RSRQ values ​​of the anchor downlink frequency unit must meet the minimum reception requirements associated with the sixth frequency unit in the S criterion. The second assumption is that one condition for a terminal to camp on an SCMC is that the measured RSRP and RSRQ values ​​of the anchor downlink frequency unit of that cell conform to the S criterion, and the measured RSRP and RSRQ values ​​of the paging downlink frequency unit also conform to the S criterion. Further, if the SCMC includes multiple uplink frequency units covering different areas, then the measured RSRP and RSRQ values ​​of the anchor downlink frequency unit, and the measured RSRP and RSRQ values ​​of the paging frequency unit, must meet the minimum reception requirements associated with the sixth frequency unit in the S criterion. The terminal can determine the paging frequency unit based on the terminal identifier and the paging configuration broadcast by the SCMC.

[0151] For example: If a cell satisfies Srxlev > 0 (power criterion) and Squal > 0 (quality criterion), then the cell is judged to satisfy the S criterion: Srxlev = Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp Squal = Q qualmeas –(Q qualmin +Q qualminoffset -Qoffset temp .

[0152] Where Srxlev is the standard power value measured by S, and Q rxlevmeas It is the measured cell received signal level (RSRP value), Q rxlevmin It is the minimum received signal level (dBm) required by the cell, Q rxlevminoffset It is aimed at Q rxlevmin The offset, P compensation It's the compensation value, Qoffset temp It is a penalty value.

[0153] Squal is the quality standard value measured by the S standard, Q. qualmeas It is the measured cell quality value (RSRQ value), Q qualmin Minimum quality level (dB) required for the community, Q qualminoffset It is aimed at Q qualmin The offset, Qoffset temp It is a penalty value.

[0154] If the SCMC neighboring cell includes K uplink frequency units, and each uplink frequency unit is configured with a Q... rxlevmin and Q rxlevmin Then the terminal selects the uplink frequency unit with the furthest coverage supported by itself out of the K uplink frequency units, corresponding to the Q value. rxlevmin and Q rxlevmin To calculate Srxlev and Squal of the SCMC neighboring cells.

[0155] The above embodiments mainly introduce how the terminal performs S-criteria verification on SCMC neighboring cells. The following will introduce the absolute frequency priority of cell reselection.

[0156] In related technologies, a cell has only one downlink frequency unit, so cell reselection based on frequency priority is easy to define. In the SCMC scenario, an SCMC neighboring cell may have multiple downlink frequency units. Therefore, how to perform cell reselection between the SCMC serving cell and the SCMC neighboring cell, and between the SCMC serving cell and the non-SCMC neighboring cell, based on frequency priority is a problem that needs to be solved.

[0157] In the following deployment scenarios, the frequency priority of the SCMC's anchor downlink frequency unit can be used to compare frequency priorities during cell reselection: 1) The SCMC is deployed on a specific frequency or frequency combination, meaning that the frequencies of all carriers of the SCMC do not overlap with the frequencies of single-carrier cells; 2) The frequencies of the SCMC serving cell and the SCMC neighboring cells also do not overlap. In this deployment scenario, the existing frequency priority comparison method can be directly reused to determine the priority.

[0158] In some deployment scenarios, the frequency of the SCMC serving cell overlaps with that of a single-carrier cell, or the SCMC serving cell and the SCMC neighboring cell have the same carrier frequency but different frequencies of their respective anchor frequency units, or the SCMC serving cell and the SCMC neighboring cell have the same anchor frequency unit frequency but different frequencies of other frequency units. In such deployment scenarios, the criteria for inter-cell reselection can be redefined.

[0159] In some embodiments, if the frequency of the serving cell overlaps with at least one frequency element of the first neighboring cell or with the frequency element of the second neighboring cell, the terminal reselects to the first neighboring cell or the second neighboring cell, provided that at least one of the following conditions is met:

[0160] 1) All at least one overlapping frequency unit satisfies the R criterion for same-frequency reselection.

[0161] 2) One of the at least one overlapping frequency units satisfies the R criterion for same-frequency reselection. Optionally, the anchor frequency unit of the first neighboring cell, i.e., the SCMC neighboring cell, must also meet a certain quality threshold. This threshold can be configured by the network-side equipment or agreed upon by the protocol.

[0162] 3) In the case where the at least one overlapping frequency unit includes an anchor frequency unit, the anchor frequency unit satisfies the R criterion for same-frequency reselection.

[0163] 4) If at least one overlapping frequency unit includes a paging frequency unit, the paging frequency unit satisfies the R criterion for same-frequency reselection. Optionally, the anchor frequency unit of the first neighboring cell, i.e., the SCMC neighboring cell, must also meet a certain quality threshold. This threshold can be configured by the network-side equipment or agreed upon by the protocol.

[0164] 5) Frequency cells that overlap with the frequency cells of the second neighboring cell satisfy the R criterion for reselection at the same frequency; wherein, the second neighboring cell is a single-frequency cell, and the neighboring cells of the serving cell include the second neighboring cell.

[0165] Considering the requirements that SCMC imposes on the capabilities of the terminals residing within it—for example, requiring the terminal to support multiple frequency units of the SCMC, and to support frequency unit switching within those multiple frequency units for paging monitoring and / or random access—it's possible that both terminals that support residing in the SCMC and those that don't may coexist. Therefore, network-side devices can configure different priority parameters for SCMC frequencies for terminals that support residing in the SCMC and those that don't. For example, for terminals that support residing in the SCMC, the network-side device can configure the SCMC frequency as a high-priority frequency or an equal-priority frequency; for terminals that don't support residing in the SCMC, the network-side device can configure the SCMC frequency as a low-priority frequency or not configure an SCMC frequency at all.

[0166] In some embodiments, the cell reselection process based on measurement results includes: obtaining frequency priority parameters of a seventh frequency unit; and performing a cell reselection process based on the measurement results and the frequency priority parameters; wherein the seventh frequency unit is the frequency unit where the first neighboring cell is located, or the frequency priority parameters are applicable to one of the following: 1) supporting terminals camped in the first cell, for example, supporting terminals camped in the SCMC; 2) not supporting terminals camped in the first cell, for example, not supporting terminals camped in the SCMC; wherein the first cell is a cell comprising at least two frequency units.

[0167] This embodiment, through the aforementioned frequency priority parameters, enables network-side equipment to flexibly and accurately control cell reselection of terminals in SCMC scenarios, thereby ensuring the communication performance of terminals and networks.

[0168] In the previous embodiment, the network-side device could configure different SCMC frequency priority parameters for terminals that support camping on the SCMC and terminals that do not support camping on the SCMC. This embodiment solves the same problem, but by introducing absolute cell priority.

[0169] In some embodiments, the method further includes: obtaining a cell list, wherein the cells in the cell list include at least one of the first neighboring cells; if the terminal supports camping on the first cell, for example, if the terminal supports camping on the SCMC, the cells in the cell list are considered as the highest priority; or, if the terminal does not support camping on the first cell, for example, if the terminal does not support camping on the SCMC, the cells in the cell list are considered as the lowest priority; wherein the first cell is a cell that includes at least two frequency units.

[0170] In this embodiment, for example, the terminal obtains a cell list, which is an SCMC (Signal-Cell Configuration Network). If the terminal supports SCMC, it considers the cells in the cell list as having the highest priority, i.e., higher than the priority of any other network configuration. If the terminal does not support SCMC, it considers the cells in the cell list as having the lowest priority, i.e., lower than the priority of any other network configuration.

[0171] Optionally, the highest priority cell reselection criteria and the lowest priority cell reselection criteria can refer to the high priority frequency cell reselection criteria and the low priority frequency cell reselection criteria.

[0172] This embodiment, through the aforementioned cell list, facilitates network-side equipment to flexibly and accurately control cell reselection of terminals in SCMC scenarios, ensuring the communication performance of terminals and networks.

[0173] In the previous embodiment, the network-side device could configure different priority parameters for SCMC frequencies for terminals that support camping on SCMC and terminals that do not support camping on SCMC. This embodiment solves the same problem, but by introducing different blacklisted cell lists.

[0174] In some embodiments, the method further includes: obtaining a blacklist of cells; wherein the blacklist of cells includes at least one of the first neighboring cells, or the blacklist of cells is applicable to one of the following: 1) terminals that support camping in the first cell, for example, terminals that support camping in the SCMC; 2) terminals that do not support camping in the first cell, for example, terminals that do not support camping in the SCMC; wherein the first cell is a cell that includes at least two frequency units.

[0175] If an uplink frequency cell in the SCMC is congested, and a terminal that only supports access on that uplink frequency cell reselects, the network-side equipment cannot perform RACH load balancing (offload) on that terminal. In this case, the network-side equipment can add that cell to its blacklist. Alternatively, for paging frequency cells, if a terminal only supports paging on a certain downlink frequency cell, it will also increase paging latency on that downlink frequency cell. Therefore, a blacklist of cells can be set for the frequency cells supported by the SCMC. For example, if the terminal only supports frequency cell 1 in the blacklist provided by the network-side equipment, then the terminal is prohibited from accessing that cell, and the terminal does not need to perform measurements on that cell.

[0176] In some embodiments, the method further includes: the terminal not performing signal measurements on cells in the blacklist cell list; or, the terminal acquiring frequency information of at least two frequency units of a second cell in the blacklist cell list, and not performing signal measurements on the second cell in the blacklist cell list if one of the following conditions is met:

[0177] 1) The terminal only supports one of the frequency units in the second cell.

[0178] 2) The terminal only supports X frequency units in the second cell, where X is a positive integer.

[0179] 3) The terminal does not support all frequency units in the second cell.

[0180] 4) The terminal does not support one of the frequency units in the second cell.

[0181] 5) The terminal does not support Y frequency units in the second cell, where Y is a positive integer.

[0182] This embodiment, through the aforementioned blacklist of cells, enables network-side devices to flexibly and accurately control cell reselection of terminals in SCMC scenarios, ensuring the communication performance of terminals and networks.

[0183] The following examples will introduce the cell reselection criteria for cells with the same frequency and the same priority but different frequencies, also known as the R criterion.

[0184] The SCMC may have limited capacity per frequency unit. If the terminal does not support paging, RACH offload operations, or frequency points within the SCMC, it will restrict the network-side equipment's flexible control over the use of SCMC's RRC IDLE / INACTIVE state resources. Therefore, the network-side equipment may control the reselection priority of SCMC and non-SCMC based on the terminal's SCMC support capability. Compared with the previous embodiments, this embodiment adjusts the SCMC priority by adjusting the R criterion parameter.

[0185] For example: Suppose there are three cells, cells 1 and 2 are SCMC cells, and cell 3 is a single-carrier cell. Cells 1 and 2 can be co-frequency or co-frequency, and cell 3 can be co-frequency.

[0186] UE1 only supports single-carrier operation, supporting one carrier in cells 1 and 2, and one carrier in cell 3; UE2 supports paging / RACH offload operation within SCMC, supporting all carriers in cell 1, some carriers in cell 2, and carriers in cell 3.

[0187] For UE1, the cell priority should be: Cell 3 > Cell 1 = Cell 2; for UE2, the cell priority could be: Cell 1 > Cell 2 > Cell 3. Alternatively, it could be other priority orders, such as Cell 3 = Cell 1 > Cell 2, which is different from UE1.

[0188] This embodiment can set Q in the R criterion based on the following formula, taking into account different terminal capabilities and cell types. offset Rs = Q meas,s +Q hyst -Q offsettemp Rn = Q meas,n -Q offset -Q offsettemp .

[0189] Where Rs is the serving cell, Rn is the neighboring cell, and Q is the value of the cell. meas This is the measured RSRP value, Q. hyst It is the hysteresis value of the measurement of the serving cell, Q. offsettemp It's the penalty value, Q. offset This is the third offset provided in the embodiments of this application.

[0190] One approach is for the terminal to calculate the third offset of the SCMC neighbor cell based on the sum of the number of downlink frequency units and the number of uplink frequency units of the supported SCMC neighbor cells.

[0191] In some embodiments, the cell reselection process based on measurement results includes: the terminal determining a third offset Q. offset The terminal is based on the measurement result Q of the first neighboring cell. meas,n The R criterion value Rn of the first neighboring cell is determined by the third offset; the third offset is related to the following information: the number of frequency units supported by the terminal in the first neighboring cell.

[0192] For example, the third offset of the SCMC neighbor cell is inversely related to the number of frequency units supported by the terminal in the SCMC neighbor cell.

[0193] For example, network-side devices configure downlink and uplink frequency unit groups. If a terminal supports a particular group, it applies the third offset corresponding to that group. If the terminal supports multiple groups, it can choose any group's third offset, or select the one with the smallest third offset.

[0194] For example, there is a mapping relationship between the number of frequency units in SCMC neighboring cells supported by the terminal and the third offset. Uplink and downlink frequency units can be counted together and mapped to a third offset, or they can be counted separately, mapped to different third offsets, and then superimposed.

[0195] In addition, for terminals that support SCMC and terminals that do not support SCMC, an offset can be added to determine the R criterion value of the first neighboring cell based on the cell type: for terminals that support SCMC, a fourth offset needs to be added to the SCMC cell to determine the R criterion value of the first neighboring cell; and / or, for terminals that do not support SCMC, a fifth offset needs to be subtracted from the SCMC cell to determine the R criterion value of the first neighboring cell.

[0196] In some embodiments, the method further includes: adding a fourth offset to the measurement result of the first neighboring cell to determine the R criterion value of the first neighboring cell; wherein the terminal is a terminal that supports camping in the first cell; or, subtracting a fifth offset from the measurement result of the first neighboring cell to determine the R criterion value of the first neighboring cell; wherein the terminal is a terminal that does not support camping in the first cell; wherein the first cell is a cell comprising at least two frequency units.

[0197] Another approach is that, for terminals that do not support SCMC, the network-side equipment can configure a cell range value N, and the terminal selects the strongest single-carrier cell from the N cells ranked highest according to the R criterion. In some embodiments, N can be agreed upon by the protocol, but whether the terminal selects the strongest single-carrier cell from the N cells ranked highest according to the R criterion based on the cell range can be configured by the network side.

[0198] In some embodiments, the cell reselection process based on measurement results includes: selecting the single-frequency cell with the strongest signal quality from the N cells ranked highest by the R criterion based on the measurement results; wherein the terminal does not support at least two frequency cells, and N is a positive integer.

[0199] This embodiment, through the aforementioned third, fourth, or fifth offset, facilitates network-side equipment in flexibly and accurately controlling cell reselection of the terminal in SCMC scenarios, thereby ensuring the communication performance of the terminal and the network.
