Description

[0045] To facilitate a better understanding of the embodiments of this application, the related technologies are described.

[0046] (1) NR cell dwelling.

[0047] When a user equipment (UE) receives a system information block (SIB) for a cell, it needs to determine the cell based on the cell's carrier bandwidth and bandwidth part (BWP) bandwidth, and combine this with the bandwidth supported by the UE itself to determine whether the cell is blocked from access.

[0048] Specifically, the terminal needs to compare its supported downlink / uplink bandwidth with the cell's normal downlink (NDL) carrier bandwidth / normal uplink (NUL) carrier bandwidth. One of the conditions for a UE to camp on the target cell is that the terminal's supported downlink bandwidth is less than or equal to the cell's NDL carrier bandwidth, but not less than the downlink BWP bandwidth on the NDL carrier; and the terminal's supported uplink bandwidth is less than or equal to the cell's NUL carrier bandwidth, but not less than the uplink BWP bandwidth on the NUL carrier.

[0049] (2) Anchor cell / Non-anchor cell.

[0050] In the 3rd Generation Partnership Project (3GPP) Version 18 Survey Project (SI), Network Energy Savings (NES) is one of the technologies that has received considerable attention. Potential technologies for network energy saving can be broadly categorized into time-domain energy saving, frequency-domain energy saving, and spatial-domain energy saving. Among these, the concept of anchored cells, as a time-domain energy saving technology, has been researched and discussed by various companies. Through network configuration information, a terminal can know that there is one anchored cell and at least one non-anchored cell near its location. Deployment scenarios for anchored and non-anchored cells include, for example... Figure 2 The non-co-location scenario shown in (a) and such Figure 2 The co-location scenario shown in (b) is a community.

[0051] Regarding network energy-saving scenarios, the following conclusions can be drawn:

[0052] 1. Non-anchored cells that do not send System Information Blocks (SIBs) are only applicable to multi-carrier scenarios;

[0053] 2. The UE is located within the coverage area of ​​one anchored cell and one or more non-anchored cells;

[0054] 3. A non-anchored cell that does not send SIBs refers to a cell in which a UE cannot receive SIBs; a non-anchored cell that does not send Synchronization Signal / Physical Broadcast Channel Block (Synchronization Signal / PBCH Block, Synchronization Signal Block, SS / PBCH Block, SSB) and SIBs refers to a cell in which a UE cannot receive either SIBs or SSBs.

[0055] 4. The UE may access the network solely through the anchored cell, or it may also be able to access it directly through a non-anchored cell. If direct access to a non-anchored cell is supported, the SIB of the anchored cell may also carry the information required for accessing the non-anchored cell;

[0056] 5. The timing, synchronization, and QCL relationships of non-anchored cells that do not send SSB and SIB need to be determined through another cell;

[0057] 6. The UE is camped in the anchored cell; the UE is not camped in a non-anchored cell that does not send SIBs, or a non-anchored cell that does not send SSBs and SIBs.

[0058] 7. Paging is not supported on non-anchored cells that do not transmit SIBs or SSBs and SIBs.

[0059] (3) Anchor carrier / Non-anchor carrier.

[0060] Narrow Band Internet of Things (NB-IoT) is built on cellular networks and consumes only about 180kHz of bandwidth. It can be directly deployed on Global System for Mobile Communications (GSM), Universal Mobile Telecommunication System (UMTS), or LTE networks to reduce deployment costs and enable smooth upgrades.

[0061] Because NB-IoT single-frequency cells only have a bandwidth of 180kHz, the remaining service channel capacity is very small after deducting the overhead of the Narrowband Primary Synchronization Signal (NPSS), Narrowband Secondary Synchronization Signal (NSSS), and SIB. To support a massive number of terminals, multiple frequency points are needed to increase network capacity. Therefore, 3GPP Release 13 introduced the concept of anchor carrier / non-anchor carrier.

[0062] In addition to anchored carriers that include NPSS, NSSS, and Narrowband Physical Broadcast Channel (NPBCH), a cell may also include at least one non-anchored carrier that does not include NPSS, NSSS, and NPBCH.

[0063] Non-anchored carriers can offload the load of anchored carriers, including SIB1 load (only TDD carriers can be offloaded), paging load, and Random Access Channel (RACH) load.

[0064] When a UE initially camps on a cell, signal quality measurements must be performed on the anchored carrier. Once the measurement relaxation conditions are met, the UE can switch to a non-anchored carrier for measurement.

[0065] When anchored and non-anchored carriers are deployed together, their coverage areas are nearly identical, both within the same 20MHz frequency band. The base station can configure Physical Random Access Channel (PRACH) resources for the UE on the anchored carrier and n non-anchored carriers, and assign an access probability 'a' to the anchored carrier. For a configuration of n non-anchored carriers, the access probability is (1-a) / n.

[0066] (4) Cell selection criteria (S criterion).

[0067] During cell selection, the terminal needs to measure the cells to be selected, i.e., perform channel measurements to assess channel quality and determine whether they meet the criteria for camping. The measurement criterion for cell selection is called the S-criteria. When the channel quality and signal strength of a cell meet the S-criteria, it may be selected as a camping cell. Meeting the S-criteria means that Srxlev > 0 and Squal > 0. Here, the power criterion is received power Srxlev > 0, and the quality criterion is the received signal quality Squal > 0 during cell search.

[0068] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp .

[0069] Wherein, Srxlev: the cell selection receive level value.

[0070] Q rxlevmeas : Measured received signal strength (RSPR) of the cell.

[0071] Q rxlevmin (Network-side configuration): Minimum received signal level for the cell. Increasing this value for a cell makes it more difficult for that cell to meet the S criterion and become a suitable cell, increasing the difficulty for the UE to select that cell, and vice versa. The value of this parameter should be such that the selected cell can provide the signal quality requirements for basic services.

[0072] Q rxlevminoffset(Network-side configuration): Minimum receive level offset for the cell. This parameter is only used when the UE is camped on a Visited Public Land Mobile Network (VPLMN) and cell selection is triggered due to periodic searches of higher-priority Public Land Mobile Networks (PLMNs). Increasing this value for a cell makes it more difficult for that cell to meet the S criterion and become a suitable cell, thus increasing the difficulty for the UE to select that cell, and vice versa.

[0073] P compensation (Network-side configuration): Used to penalize UEs that fail to reach the cell's maximum power. When the UE's maximum allowed transmit power is less than or equal to the maximum transmit power supported by the UE's capabilities, P... compensation =0. When the UE's maximum allowed transmit power exceeds the UE's maximum supported transmit power, P compensation = UE maximum allowed transmit power - UE capability supports maximum transmit power.

[0074] Qoffset temp (Network side configuration): Temporary offset applied to this cell. This value is configured in the ConnEstFailOffset parameter in RRC and is used for connection failure control.

[0075] Squal = Q qualmeas –(Q qualmin +Q qualminoffset -Qoffset temp .

[0076] Squal: Cell selection quality value.

[0077] Q qualmeas : Measured cell quality value (RSRQ).

[0078] Q qualmin (Network-side configuration): Minimum received signal quality. This parameter represents the minimum received signal quality required for cell reselection and controls the ease of cell reselection. This parameter is issued in SIB5. Increasing this value for a cell makes it more difficult for the cell to meet the S criterion and become a suitable cell, thus increasing the difficulty for the UE to select that cell, and vice versa.

[0079] Q qualminoffset(Network-side configuration): Minimum received signal quality offset value. This parameter represents the minimum received signal quality offset of a cell and is applied to the cell selection criterion (S-criterion) formula. This parameter is only used when the UE is camped on a VPLMN and cell selection is triggered due to periodic searches of higher-priority PLMNs. Increasing this value for a cell makes it more difficult for that cell to meet the S-criterion and become a suitable cell, thus increasing the difficulty for the UE to select that cell, and vice versa.

[0080] Qoffset temp (Network side configuration): Temporary offset applied to this cell. This value is configured in the ConnEstFailOffset parameter in RRC and is used for connection failure control.

[0081] The cell dwelling method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0082] Figure 3 This is a schematic flowchart of a cell dwelling method 200 according to an embodiment of this application.

[0083] like Figure 3 As shown, the community dwelling method 200 may include at least some of the following:

[0084] S201, the terminal receives the first configuration information.

[0085] The first configuration information includes uplink configuration information or downlink configuration information. The uplink configuration information is used to configure at least one of the following: at least one first uplink frequency domain resource unit and at least one second uplink frequency domain resource unit on the at least one first uplink frequency domain resource unit. The downlink configuration information is used to configure at least one of the following: at least one first downlink frequency domain resource unit and at least one second downlink frequency domain resource unit on the at least one first downlink frequency domain resource unit.

[0086] For example, the first uplink frequency domain resource unit and the second uplink frequency domain resource unit are initial uplink frequency domain resource units with different resource granularities. For instance, the bandwidth of the first uplink frequency domain resource unit is greater than the bandwidth of the second uplink frequency domain resource unit, or the first uplink frequency domain resource unit includes the second uplink frequency domain resource. Similarly, the first downlink frequency domain resource unit and the second downlink frequency domain resource unit are initial downlink frequency domain resource units with different resource granularities. For instance, the bandwidth of the first downlink frequency domain resource unit is greater than the bandwidth of the second downlink frequency domain resource, or the first downlink frequency domain resource unit includes the second downlink frequency domain resource.

[0087] For example, the uplink configuration information is used to configure multiple first uplink frequency domain resource units, or the uplink configuration information is used to configure multiple second uplink frequency domain resource units; the downlink configuration information is used to configure multiple first downlink frequency domain resource units, or the downlink configuration information is used to configure multiple second downlink frequency domain resource units.

[0088] It should be noted that the frequency domain resource units involved in this application may include at least one of the following: one or more resource blocks (RBs), one or more resource element groups (REGs), one or more resource block groups (RBGs), one or more bandwidth parts (BWPs), one or more carriers, and one or more frequency bands. This application does not specifically limit these.

[0089] It should be noted that this application does not limit the deployment method of the at least one first uplink frequency domain resource unit, the at least one second uplink frequency domain resource unit, the at least one first downlink frequency domain resource unit, and the at least one second downlink frequency domain resource unit.

[0090] S202, the terminal determines, based on the first configuration information, whether the terminal meets the conditions for being able to camp on the first cell or the terminal does not meet the conditions for being able to camp on the first cell.

[0091] For example, the conditions under which the terminal can camp on the first cell may include bandwidth conditions for the terminal to camp on the first cell. For instance, if the terminal determines, based on the first configuration information, that it meets the conditions for camping on the first cell, it means that the terminal meets the bandwidth conditions for camping on the first cell. In this case, the terminal can continue to determine whether other conditions for camping on the first cell are met or not. For example, the terminal can continue to determine whether the S criterion is met or not. For example, for a first downlink frequency domain resource element that meets the bandwidth conditions, if the S criterion is met, it is determined that the terminal can camp on the first cell; if the S criterion is not met, it is determined that the terminal cannot camp on the first cell. If the terminal determines, based on the first configuration information, that it does not meet the conditions for camping on the first cell, it means that the terminal does not meet the bandwidth conditions for camping on the first cell. In this case, the terminal can determine that the first cell cannot camp on.

[0092] For example, the frequency domain resource units supported by the first cell include the frequency domain resource units configured by the first configuration information.

[0093] In this embodiment of the application, the terminal determines, based on the first configuration information, whether the terminal meets the conditions for camping in the first cell or not. This can reduce the probability of the terminal failing to camp due to the terminal not considering the information configured by the network-side equipment, thereby improving the success rate of camping in the cell.

[0094] It should be noted that the first cell can be a cell that supports non-anchored resources, a non-anchored cell, a cell that supports carrier aggregation, a single cell multi-band / carrier / BWP (SCMX) cell, or a cell that only supports uplink or downlink transmission.

[0095] Among them, SCMX cells include single cell multi-band (SCMB) cells, single cell multi-carrier (SCMC) cells, and single cell multi-BWP (SCM-BWP) cells.

[0096] In other words, the solution provided in this application is not limited to the decision on the campability of a single-band single-carrier cell. The terminal may camp on a non-anchored cell, a cell that supports carrier aggregation, an SCMX cell, or a cell that only supports uplink or downlink transmission, thereby improving the success rate of cell camping.

[0097] For example, when the first cell is an SCMC cell, it can support deployment scenarios for NUL carriers, SUL carriers, and NDL carriers. In this case, if the cell camping determination adopts a single-band, single-carrier-oriented method, then the bandwidth conditions for the terminal to camp on the first cell are met, including: the downlink bandwidth supported by the terminal is less than or equal to the NDL carrier bandwidth of the cell, and not less than the downlink BWP bandwidth on the NDL carrier; the uplink bandwidth supported by the terminal is less than or equal to the NUL carrier bandwidth of the cell, and not less than the uplink BWP bandwidth on the NUL carrier. That is, the terminal first determines whether the cell is allowed to camp based on the NDL carrier bandwidth / NUL carrier bandwidth, and then determines the availability of SUL based on whether the terminal's uplink bandwidth supports SUL carrier bandwidth. If the uplink bandwidth supported by the terminal does not support SUL carrier bandwidth, it is considered that no SUL carrier is configured, but this does not affect the terminal's determination of cell camping availability through NDL carrier bandwidth / NUL carrier bandwidth. It can be seen that the terminal will not use SUL carrier bandwidth for cell camping determination. In other words, for deployment scenarios using NDL carriers and NUL / SUL carriers, a cell can have at most one downlink and two uplink carriers. If a terminal meets the SUL carrier bandwidth requirement but not the NUL carrier bandwidth requirement, and if the terminal relies on a single-band, single-carrier resource granularity to determine cell campability, the terminal cannot camp on that cell. However, if the identities of NUL and SUL carriers are not distinguished, and they are treated as equal uplink resources, the terminal should only need to meet the bandwidth requirement of one of the uplink carriers to be considered to meet the bandwidth requirement for camping on the first cell. In this embodiment, the first configuration information is used to configure the at least one first uplink frequency domain resource unit. When the at least one uplink frequency domain resource unit includes an NUL carrier, it is equivalent to being able to determine the campability of the first cell based on the SUL carrier. This reduces the probability of terminal camping failure due to relying solely on the NUL carrier for cell camping determination, thereby improving the cell camping success rate.

[0098] For example, when the at least one first uplink frequency domain resource unit includes an uplink non-anchored resource unit, such as a non-anchored carrier, or when the at least one first downlink frequency domain resource unit includes a downlink non-anchored resource unit, such as a non-anchored carrier, it is equivalent to being able to make a dwell determination for the first cell based on the non-anchored carrier. That is, the terminal may be able to dwell in a cell that supports non-anchored resource units, thereby improving the success rate of cell dwelling. Similarly, when the at least one second uplink frequency domain resource unit includes an uplink non-anchored resource unit, such as a non-anchored BWP, or when the at least one second downlink frequency domain resource unit includes a downlink non-anchored resource unit, such as a non-anchored BWP, it is equivalent to being able to make a dwell determination for the first cell based on the non-anchored resource unit. That is, the terminal may be able to dwell in a cell that supports non-anchored carriers, thereby improving the success rate of cell dwelling.

[0099] For example, if the first configuration information only includes uplink configuration information or downlink configuration information, it means that the terminal can determine whether it meets the conditions for camping in the first cell or does not meet the conditions for camping in the first cell based solely on the uplink frequency domain resource units configured by the uplink configuration information or the downlink frequency domain resource units configured by the downlink configuration information. This is equivalent to making a campability decision for cells that only support uplink or downlink transmission, meaning that the terminal may camp in a cell that only supports uplink or downlink transmission, thereby improving the success rate of cell camping.

[0100] It should be noted that the terms "non-anchored cell" or "non-anchored carrier" used in this application can be understood as terms used in different scenarios. However, in this invention, these terms are mainly used to describe non-anchored resources corresponding to the concepts of anchored cell or anchored carrier. Furthermore, to simplify the description of this application, some embodiments do not use specific anchored / non-anchored cells or anchored / non-anchored carriers as examples, but only use terms such as anchored resources or non-anchored resources to describe the method. The anchored resources or non-anchored resources can be frequency-domain related resources such as cells, carriers, carrier combinations, BWPs, BWP combinations, frequency bands, frequency band combinations, etc. The anchored / non-anchored terms used in this application can also be replaced by terms with similar or identical meanings such as Primary / Secondary, Primary / Secondary, Major / Minor. This application does not impose specific limitations in this regard.

[0101] In some embodiments, the first uplink frequency domain resource unit is an uplink carrier or a set of uplink carriers, and the second uplink frequency domain resource unit is an uplink BWP or a set of uplink BWPs; the first downlink frequency domain resource unit is a downlink carrier or a set of downlink carriers, and the second downlink frequency domain resource unit is a downlink BWP or a set of downlink BWPs.

[0102] For example, one or more BWPs can be configured on a single carrier, including but not limited to normal BWPs and reduced capability (RedCap) BWPs. The bandwidth of a normal UE is greater than or equal to the bandwidth of a normal BWP.

[0103] In this embodiment, when the first uplink frequency domain resource unit is an uplink carrier set, or the second uplink frequency domain resource unit is an uplink BWP set, or the first downlink frequency domain resource unit is a downlink carrier set, or the second downlink frequency domain resource unit is a downlink BWP set, the cell campability determination of the first cell can be realized based on the carrier set or the BWP set. This can reduce the probability of terminal camping failure caused by relying on only a single carrier or a single BWP when determining cell campability, thereby improving the success rate of cell camping.

[0104] The following is an exemplary description of the specific implementation of the frequency domain resource units supported by the first cell.

[0105] 1. The first cell supports one first downlink frequency domain resource element and multiple first uplink frequency domain resource elements, and each first downlink frequency domain resource element supports one second downlink frequency domain resource element, and each first uplink frequency domain resource element supports one second uplink frequency domain resource element. For example, the first cell supports one initial downlink carrier / carrier set and multiple initial uplink carrier / carrier sets, and each carrier / carrier set supports a single initial BWP / BWP set. For example, the first cell is a cell that supports NUL carriers, SUL carriers, and NDL carriers.

[0106] 2. The first cell supports multiple first downlink frequency domain resource units and multiple first uplink frequency domain resource units, and each first downlink frequency domain resource unit supports one second downlink frequency domain resource unit, and each first uplink frequency domain resource unit supports one second uplink frequency domain resource unit. For example, the first cell supports multiple initial downlink carriers / carrier sets and multiple initial uplink carriers / carrier sets, and each carrier / carrier set supports a single initial BWP / BWP set. For example, the first cell is an SCMB cell.

[0107] 3. The first cell supports one first downlink frequency domain resource unit and one first uplink frequency domain resource unit, and each first downlink frequency domain resource unit supports multiple second downlink frequency domain resource units, and each first uplink frequency domain resource unit supports multiple second uplink frequency domain resource units. For example, the first cell supports one initial downlink carrier / carrier set and one initial uplink carrier / carrier set, and each carrier / carrier set supports multiple initial BWP / BWP sets. For example, the first cell is an SCMB cell.

[0108] 4. The first cell supports multiple first downlink frequency domain resource units and multiple first uplink frequency domain resource units, and each first downlink frequency domain resource unit supports multiple second downlink frequency domain resource units, and each first uplink frequency domain resource unit supports multiple second uplink frequency domain resource units. For example, the first cell supports multiple initial downlink carriers / carrier sets and multiple initial uplink carriers / carrier sets, and each carrier / carrier set supports multiple initial BWP / BWP sets. For example, the first cell is an SCMB cell.

[0109] It should be noted that the frequency domain resource units supported by the first cell mentioned above are merely examples in this application and should not be construed as limiting this application.

[0110] In some embodiments, S202 includes:

[0111] Based on the first configuration information, the terminal determines that it meets the conditions for being able to camp on the first cell if the first condition is met.

[0112] The first condition includes at least one of the following:

[0113] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the third uplink frequency domain resource unit, wherein the third uplink frequency domain resource unit includes at least one of the following: any first uplink frequency domain resource unit in a portion of the at least one first uplink frequency domain resource unit, any first uplink frequency domain resource unit in the at least one first uplink frequency domain resource unit, and a specific first uplink frequency domain resource unit in the at least one first uplink frequency domain resource unit.

[0114] The uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth uplink frequency domain resource unit, and the fourth uplink frequency domain resource unit includes at least one of the following: any second uplink frequency domain resource unit in a portion of the at least one second uplink frequency domain resource unit, any second uplink frequency domain resource unit in the at least one second uplink frequency domain resource unit, and a specific second uplink frequency domain resource unit in the at least one second uplink frequency domain resource unit.

[0115] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the third downlink frequency domain resource unit, wherein the third downlink frequency domain resource unit includes at least one of the following: any first downlink frequency domain resource unit in a portion of the at least one first downlink frequency domain resource unit, any first downlink frequency domain resource unit in the at least one first downlink frequency domain resource unit, or the bandwidth of a specific first downlink frequency domain resource unit in the at least one first downlink frequency domain resource unit.

[0116] The downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth downlink frequency domain resource unit, and the fourth downlink frequency domain resource unit includes at least one of the following: any second downlink frequency domain resource unit in a portion of the at least one second downlink frequency domain resource unit, any second downlink frequency domain resource unit in the at least one second downlink frequency domain resource unit, and a specific second downlink frequency domain resource unit in the at least one second downlink frequency domain resource unit.

[0117] For example, the first condition includes the various condition options mentioned above.

[0118] For example, the first condition includes:

[0119] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the third uplink frequency domain resource unit, the uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth uplink frequency domain resource unit, the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the third downlink frequency domain resource unit, and the downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth downlink frequency domain resource unit.

[0120] For example, the first condition includes the uplink-related or downlink-related condition options mentioned above.

[0121] For example, if the first cell is a cell that only supports uplink transmission, then the first condition includes: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the third uplink frequency domain resource unit, and the uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth uplink frequency domain resource unit. If the first cell is a cell that only supports downlink transmission, then the first condition includes: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the third downlink frequency domain resource unit, and the downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth downlink frequency domain resource unit.

[0122] For example, the first condition also includes other conditions under which the terminal can reside in the first cell.

[0123] For example, the third downlink frequency domain resource unit satisfies the S-criterion for cell camping. For example, the at least one first downlink frequency domain resource unit is two downlink carriers, such as a first downlink carrier and a second downlink carrier. When the terminal determines that the downlink bandwidth supported by the terminal and the first downlink carrier meet the bandwidth condition for the terminal to camp in the first cell, but the downlink bandwidth supported by the terminal and the second downlink carrier do not meet the bandwidth condition for the terminal to camp in the first cell, the terminal needs to further determine that the first downlink carrier meets the S-criterion for cell camping before considering that the terminal can camp in the first cell.

[0124] In this embodiment, the first condition includes at least one of the following: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the third uplink frequency domain resource unit, or the uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth uplink frequency domain resource unit; or if the first condition includes at least one of the following: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the third downlink frequency domain resource unit, or the downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth downlink frequency domain resource unit, it indicates that the terminal may be able to camp on a cell that only supports uplink or downlink transmission, thereby improving the success rate of cell camping.

[0125] In some embodiments, S202 includes:

[0126] Based on the first configuration information, if the second condition is met, the terminal determines that the terminal does not meet the conditions for being able to camp on the first cell.

[0127] The second condition includes at least one of the following:

[0128] The uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third uplink frequency domain resource unit, and the third uplink frequency domain resource unit includes at least one of the following: any first uplink frequency domain resource unit in a portion of the at least one first uplink frequency domain resource unit, any first uplink frequency domain resource unit in the at least one first uplink frequency domain resource unit, and a specific first uplink frequency domain resource unit in the at least one first uplink frequency domain resource unit.

[0129] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth uplink frequency domain resource unit, and the fourth uplink frequency domain resource unit includes at least one of the following: any second uplink frequency domain resource unit in a portion of the at least one second uplink frequency domain resource unit, any second uplink frequency domain resource unit in the at least one second uplink frequency domain resource unit, and a specific second uplink frequency domain resource unit in the at least one second uplink frequency domain resource unit.

[0130] The downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third downlink frequency domain resource unit, wherein the third downlink frequency domain resource unit includes at least one of the following: any first downlink frequency domain resource unit in a portion of the at least one first downlink frequency domain resource unit, any first downlink frequency domain resource unit in the at least one first downlink frequency domain resource unit, and the bandwidth of a specific first downlink frequency domain resource unit in the at least one first downlink frequency domain resource unit.

[0131] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth downlink frequency domain resource unit, which includes at least one of the following: any second downlink frequency domain resource unit in a subset of the at least one second downlink frequency domain resource units, any second downlink frequency domain resource unit in the at least one second downlink frequency domain resource unit, or a specific second downlink frequency domain resource unit in the at least one second downlink frequency domain resource unit.

[0132] For example, the second condition includes the various condition options mentioned above.

[0133] For example, the second condition includes:

[0134] The uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third uplink frequency domain resource unit, or the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth uplink frequency domain resource unit, or the downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third downlink frequency domain resource unit, or the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth downlink frequency domain resource unit.

[0135] For example, the second condition includes the uplink-related or downlink-related condition options mentioned above.

[0136] For example, if the first cell is a cell that only supports uplink transmission, then the second condition includes: the uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third uplink frequency domain resource unit, or the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth uplink frequency domain resource unit. If the first cell is a cell that only supports downlink transmission, then the second condition includes: the downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third downlink frequency domain resource unit, or the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth downlink frequency domain resource unit.

[0137] For example, the second condition also includes other conditions under which the terminal can reside in the first cell.

[0138] For example, the third downlink frequency domain resource element does not meet the S-criterion for cell camping. For example, the at least one first downlink frequency domain resource element is two downlink carriers, such as a first downlink carrier and a second downlink carrier. When the terminal determines that the downlink bandwidth supported by the terminal and the first downlink carrier meet the bandwidth condition for the terminal to camp in the first cell, but the downlink bandwidth supported by the terminal and the second downlink carrier do not meet the bandwidth condition for the terminal to camp in the first cell, the terminal needs to further determine that the first downlink carrier does not meet the S-criterion for cell camping before considering the first cell unsuitable for camping.

[0139] In this embodiment, the second condition includes at least one of the following: the uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third uplink frequency domain resource unit, and the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth uplink frequency domain resource unit; or if the second condition includes at least one of the following: the downlink bandwidth supported by the terminal is greater than or equal to the bandwidth of the third downlink frequency domain resource unit, and the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the fourth downlink frequency domain resource unit, it indicates that the terminal can perform a dwell determination on cells that only support uplink or downlink transmission, and the terminal may dwell on a cell that only supports uplink or downlink transmission, thereby improving the cell dwell success rate.

[0140] In some embodiments, the third uplink frequency domain resource unit and the third downlink frequency domain resource unit are associated, or

[0141] The third uplink frequency domain resource unit is associated with the fourth uplink frequency domain resource unit, or

[0142] The third downlink frequency domain resource unit is associated with the fourth downlink frequency domain resource unit, or

[0143] The fourth uplink frequency domain resource unit is associated with the fourth downlink frequency domain resource unit.

[0144] For example, the association between the third uplink frequency domain resource unit and the third downlink frequency domain resource unit, and the association between the fourth uplink frequency domain resource unit and the fourth downlink frequency domain resource unit, can be a correspondence relationship. The association between the third uplink frequency domain resource unit and the fourth uplink frequency domain resource unit, and the association between the third downlink frequency domain resource unit and the fourth downlink frequency domain resource unit, can be a subordinate relationship or an inclusion relationship.

[0145] In this embodiment, by refining the association between frequency domain resource units, the stationing status of the first cell can be judged based on frequency domain resource units with existing associations. This can reduce the probability of the terminal failing to station when judging cell stationing based on frequency domain resource units without existing associations because the cell does not support frequency domain resource units without existing associations, thereby improving the success rate of cell stationing.

[0146] In some embodiments, if the third uplink frequency domain resource unit includes a plurality of fifth uplink frequency domain resource units, then the bandwidth of the third uplink frequency domain resource unit is at least one of the following: the minimum bandwidth among the bandwidths of the plurality of fifth uplink frequency domain resource units, the maximum bandwidth among the bandwidths of the plurality of fifth uplink frequency domain resource units, the sum of the bandwidths of the plurality of fifth uplink frequency domain resource units, and the bandwidth from the lowest frequency point to the highest frequency point of the at least one fifth uplink frequency domain resource unit; or

[0147] If the fourth uplink frequency domain resource unit includes multiple sixth uplink frequency domain resource units, then the bandwidth of the fourth uplink frequency domain resource unit is at least one of the following: the minimum bandwidth among the bandwidths of the multiple sixth uplink frequency domain resource units, the maximum bandwidth among the bandwidths of the multiple sixth uplink frequency domain resource units, the sum of the bandwidths of the multiple sixth uplink frequency domain resource units, and the bandwidth from the lowest frequency point to the highest frequency point of the at least one sixth uplink frequency domain resource unit; or

[0148] If the third downlink frequency domain resource unit includes multiple fifth downlink frequency domain resource units, then the bandwidth of the third downlink frequency domain resource unit is at least one of the following: the minimum bandwidth among the bandwidths of the multiple fifth downlink frequency domain resource units, the maximum bandwidth among the bandwidths of the multiple fifth downlink frequency domain resource units, the sum of the bandwidths of the multiple fifth downlink frequency domain resource units, and the bandwidth from the lowest frequency point to the highest frequency point of the at least one fifth downlink frequency domain resource unit; or

[0149] If the fourth downlink frequency domain resource unit includes a plurality of sixth downlink frequency domain resource units, then the bandwidth of the fourth downlink frequency domain resource unit is at least one of the following: the minimum bandwidth among the bandwidths of the plurality of sixth downlink frequency domain resource units, the maximum bandwidth among the bandwidths of the plurality of sixth downlink frequency domain resource units, the sum of the bandwidths of the plurality of sixth downlink frequency domain resource units, and the bandwidth from the lowest frequency point to the highest frequency point of the at least one sixth downlink frequency domain resource unit.

[0150] For example, if the first downlink frequency domain resource element is a downlink carrier, then the bandwidth of the downlink carrier is associated with its PSS bandwidth, SSS bandwidth, or SSB bandwidth. If the second downlink frequency domain resource element is a downlink BWP, then the downlink BWP is associated with a Control Resource Set (CORESET), terminal type, or terminal service.

[0151] In this embodiment, the terminal determines the stationing capability of the first cell based on the minimum bandwidth, maximum bandwidth, bandwidth and / or the bandwidth from the lowest frequency point to the highest frequency point of the frequency domain resource unit. This can reduce the probability of stationing failure caused by using only a specific bandwidth when determining cell stationing capability, thereby improving the success rate of cell stationing.

[0152] In some embodiments, the specific first uplink frequency domain resource unit includes at least one of the following: an anchored first uplink frequency domain resource unit, a first uplink frequency domain resource unit with the largest bandwidth, a first uplink frequency domain resource unit with the smallest bandwidth, or a first uplink frequency domain resource unit associated with the characteristics of the terminal; or

[0153] The specific second uplink frequency domain resource unit includes at least one of the following: an anchored second uplink frequency domain resource unit, a second uplink frequency domain resource unit with the largest bandwidth, a second uplink frequency domain resource unit with the smallest bandwidth, or a second uplink frequency domain resource unit associated with the characteristics of the terminal; or

[0154] The specific first downlink frequency domain resource unit includes at least one of the following: an anchored first downlink frequency domain resource unit, a first downlink frequency domain resource unit with the largest bandwidth, a first downlink frequency domain resource unit with the smallest bandwidth, or a first downlink frequency domain resource unit associated with the characteristics of the terminal; or

[0155] The specific second downlink frequency domain resource unit includes at least one of the following: an anchored second downlink frequency domain resource unit, a second downlink frequency domain resource unit with the largest bandwidth, a second downlink frequency domain resource unit with the smallest bandwidth, and a second downlink frequency domain resource unit associated with the characteristics of the terminal.

[0156] For example, the anchored first uplink frequency domain resource unit can be an anchored uplink carrier, and the anchored second uplink frequency domain resource unit can be an anchored uplink BWP; the anchored first downlink frequency domain resource unit can be an anchored downlink carrier, and the anchored second downlink frequency domain resource unit can be an anchored downlink BWP.

[0157] In this embodiment, the terminal determines the stationing status of the first cell based on the frequency domain resource units that are anchored, have the largest bandwidth, have the smallest bandwidth, and are associated with the characteristics of the terminal. This reduces the capability requirements of the terminal and thus reduces the complexity of the terminal.

[0158] In some embodiments, the first configuration information is further used to configure at least one of the following:

[0159] The set of characteristics associated with at least one first uplink frequency domain resource unit;

[0160] The set of characteristics associated with at least one second uplink frequency domain resource unit;

[0161] The set of characteristics associated with at least one first downlink frequency domain resource unit;

[0162] The set of characteristics associated with at least one second downlink frequency domain resource unit;

[0163] The feature set includes the features of the terminal.

[0164] For example, the feature set may include one or more features. In other words, the first configuration information is also used to configure at least one of the following:

[0165] At least one characteristic associated with the at least one first uplink frequency domain resource unit;

[0166] At least one characteristic associated with the at least one second uplink frequency domain resource unit;

[0167] At least one characteristic associated with the at least one first downlink frequency domain resource unit;

[0168] At least one characteristic associated with the at least one second downlink frequency domain resource unit;

[0169] The at least one characteristic includes the characteristics of the terminal.

[0170] For example, the terminal may, based on at least one characteristic associated with the at least one first uplink frequency domain resource unit, determine a first uplink frequency domain resource matching the characteristics of the terminal as the third uplink frequency domain resource unit. Alternatively, the terminal may, based on at least one characteristic associated with the at least one second uplink frequency domain resource unit, determine a second uplink frequency domain resource matching the characteristics of the terminal as the fourth uplink frequency domain resource unit. Alternatively, the terminal may, based on at least one characteristic associated with the at least one first downlink frequency domain resource unit, determine a first downlink frequency domain resource matching the characteristics of the terminal as the third downlink frequency domain resource unit. Alternatively, the terminal may, based on at least one characteristic associated with the at least one second downlink frequency domain resource unit, determine a second downlink frequency domain resource matching the characteristics of the terminal as the fourth downlink frequency domain resource unit.

[0171] For example, the feature set includes at least one of the following:

[0172] 1. The bandwidth supported by the frequency domain resource unit; it can be a single bandwidth or a list / combination of bandwidths.

[0173] 2. UE types supported by the frequency domain resource unit; it can be a single UE type or a list / combination of UE types.

[0174] For example, the UE types mentioned are Internet of Things (IoT) UE, Artificial Intelligence of Things (AIOT) UE, RedCap UE, Non-Terrestrial Network (NTN) UE, Very Small Aperture Terminal (VSAT) UE, etc.

[0175] For example, the UE type list is IOT UE, AIOT UE, RedCap UE, which means that as long as the UE type is included in any of the UE types in the list, the UE can use the frequency domain resource unit;

[0176] For example, the UE type combination is AIOT UE and RedCap UE, indicating that the UE type supports both AIOT UE and RedCap UE UE types, and can use the frequency domain resource unit; for example, the UE is a smartwatch in the factory product testing phase, which is a RedCap UE equipped with an AIOT module.

[0177] 3. UE capabilities supported by the frequency domain resource element; it can be a single UE capability or a list / combination of UE capabilities.

[0178] For example, the UE capabilities include the number of Tx / Rx antennas supported by the UE, whether it supports multi-active BWP, and the channel bandwidth supported by the UE.

[0179] 4. Parameters supported by the frequency domain resource unit, such as UE power consumption level or UE power consumption status, can be a UE power consumption level / UE power consumption status, or a list / combination of UE power consumption levels / UE power consumption status.

[0180] For example, UE power consumption level indicates the level of power consumption of the UE when performing services. For example, Extended Reality (XR) services performed by the UE are high power consumption services.

[0181] For example, UE power status indicates the UE's current remaining battery power. For example, the UE has low remaining battery power.

[0182] 5. Services supported by the frequency domain resource unit; it can be a single UE service or a list / combination of UE services.

[0183] For example, the UE services include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communication (URLLC), Massive Machine Type Communication (mMTC), emergency services, XR services, and Device to Device (D2D) services.

[0184] In this embodiment, when the terminal determines the stationing status of the first cell based on frequency domain resource units whose characteristics match those of the terminal, it can reduce the probability of stationing failure caused by the mismatch between the frequency domain resource units used to determine the stationing status of the first cell and the characteristics of the terminal, thereby improving the success rate of cell stationing.

[0185] In some embodiments, the characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal.

[0186] For example, the terminal type includes, but is not limited to, RedCap UE or VSAT UE. For instance, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with the terminal type, such as VSAT. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with VSAT UE.

[0187] For example, the capabilities supported by the terminal include, but are not limited to, support for RedCap, support for NTN, or support for Multimedia Broadcast Service (MBS), etc.

[0188] For example, the parameters supported by the terminal include, but are not limited to, the uplink / downlink channel bandwidth supported by the terminal, the terminal's power consumption status (such as high / medium / low power, such as power percentage), and the number of Tx / Rx antennas of the terminal.

[0189] For example, the services supported by the terminal include, but are not limited to, eMBB, URLLC, or MBS. For instance, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping in the first cell is associated with a service supported by the terminal, such as URLLC. Therefore, when the UE's terminal type is a VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping in the first cell is associated with URLLC.

[0190] In this embodiment, the characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal. This means that the frequency domain resource units used to determine the residency of the first cell can be selected from different dimensions, thereby improving the flexibility of cell residency determination.

[0191] In some embodiments, the uplink configuration information is associated with the subcarrier spacing (SCS) or parameter set (numerology) of the first uplink frequency domain resource unit, or

[0192] The uplink configuration information is associated with the subcarrier spacing SCS or parameter set of the second uplink frequency domain resource unit, or the downlink configuration information is associated with the subcarrier spacing SCS or parameter set of the first downlink frequency domain resource unit, or the downlink configuration information is associated with the subcarrier spacing SCS or parameter set of the second downlink frequency domain resource unit.

[0193] In this embodiment, by refining the relationship between configuration information and frequency domain resource units, the complexity of the configuration information can be reduced.

[0194] The cell dwelling method provided in this application will be described below with reference to various embodiments.

[0195] Example 1:

[0196] In this embodiment, the first downlink frequency domain resource unit is the initial downlink carrier, the second downlink frequency domain resource unit is the initial downlink BWP, the first uplink frequency domain resource unit is the initial uplink carrier, and the second uplink frequency domain resource unit is the initial uplink BWP.

[0197] For example, the deployment scenario in this embodiment is: the first cell supports one initial downlink carrier and multiple initial uplink carriers for random access, and each carrier supports a single initial BWP. For example, the first cell is a cell that supports NUL carriers, SUL carriers, and NDL carriers.

[0198] In this embodiment, the terminal can determine the campability of the first cell by following these steps:

[0199] Step 1:

[0200] The terminal receives first configuration information from the first cell, the first configuration information including:

[0201] Downlink configuration information, which includes:

[0202] The bandwidth of the initial downlink carrier;

[0203] The initial downlink BWP bandwidth;

[0204] At least one uplink configuration information, the uplink configuration information including:

[0205] The bandwidth of the initial uplink carrier;

[0206] The initial uplink bandwidth of the BWP.

[0207] For example, a network-side device can configure one or more uplink configuration messages, each of which carries carrier configuration information for an initial uplink carrier. The carrier configuration information for the initial uplink carrier includes the bandwidth of the initial uplink carrier and the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0208] For example, a network-side device can be configured with uplink configuration information, which carries a list of carrier configuration information including an initial uplink carrier. This list contains carrier configuration information for one or more initial uplink carriers. The carrier configuration information for the initial uplink carrier includes the bandwidth of the initial uplink carrier and the bandwidth of the initial uplink BWP on that initial uplink carrier.

[0209] Step 2:

[0210] The terminal determines that it meets the conditions for being able to camp on the first cell or determines that it does not meet the conditions for being able to camp on the first cell.

[0211] Step 2-1:

[0212] Based on the first configuration information, the terminal determines that it meets the conditions for camping on the first cell if a first condition is satisfied; wherein the first condition includes at least one of the following:

[0213] 1. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier.

[0214] For example, the terminal receives first configuration information from a first cell. The terminal may support one or more downlink bandwidths. If the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier and greater than or equal to the bandwidth of the initial downlink BWP, then the terminal determines that it meets the conditions for camping in the first cell. Optionally, the downlink configuration information is associated with the SCS of the initial downlink BWP.

[0215] 2. For at least a portion of the initial uplink carriers among all the initial uplink carriers configured by the at least one uplink configuration information, the terminal has a supported uplink bandwidth that is less than or equal to the bandwidth of each initial uplink carrier and greater than or equal to the bandwidth of the initial uplink BWP of each initial uplink carrier.

[0216] In other words, there exists at least one initial uplink carrier such that the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP of the initial uplink carrier.

[0217] For example, the terminal receives first configuration information from a first cell. The first configuration information includes one or more uplink configuration information (e.g., initial uplink carrier configuration information). The terminal may support one or more uplink bandwidths. If an uplink bandwidth supported by the terminal is less than or equal to the initial uplink carrier bandwidth of at least one initial uplink carrier (e.g., initial uplink carrier 1), and greater than or equal to the bandwidth of the initial uplink BWP of the at least one initial uplink carrier (e.g., initial uplink carrier 1), then the terminal determines that it meets the conditions for camping in the first cell. Optionally, the uplink configuration information is associated with the SCS of the initial uplink BWP.

[0218] For example, the first cell indicates the configuration information of three initial uplink carriers (e.g., initial uplink carrier 1, initial uplink carrier 2, and initial uplink carrier 3). If the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of initial uplink carrier 1, and greater than or equal to the bandwidth of the initial uplink BWP on initial uplink carrier 1, then the conditions for camping in the first cell are met. Similarly, if for initial uplink carrier 1, the uplink bandwidth BW1 supported by the terminal is less than or equal to the bandwidth of initial uplink carrier 1, and greater than or equal to the bandwidth of the initial uplink BWP on initial uplink carrier 1, and for initial uplink carrier 2, the uplink bandwidth BW2 supported by the terminal is less than or equal to the bandwidth of initial uplink carrier 2, and greater than or equal to the bandwidth of the initial uplink BWP on initial uplink carrier 2, then the conditions for camping in the first cell are also met.

[0219] Beneficial effects: Through this implementation method, as long as the uplink bandwidth supported by the terminal has at least one uplink bandwidth that can meet the condition of "less than or equal to the bandwidth of the initial uplink carrier and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier", it can be determined that the terminal meets the conditions for camping in the first cell. The requirements for the terminal's capabilities are not high, which helps to reduce the complexity of the terminal.

[0220] 3. For each of the initial uplink carriers configured in the at least one uplink configuration information, the terminal has a supported uplink bandwidth that is less than or equal to the bandwidth of each initial uplink carrier and greater than or equal to the bandwidth of the initial uplink BWP of each initial uplink carrier.

[0221] For example, the first cell indicates configuration information for three initial uplink carriers (e.g., initial uplink carrier 1, initial uplink carrier 2, and initial uplink carrier 3). If, for initial uplink carrier 1, the terminal supports an uplink bandwidth BW1 that is less than or equal to the bandwidth of initial uplink carrier 1 and greater than or equal to the bandwidth of the initial uplink BWP of initial uplink carrier 1; simultaneously, for initial uplink carrier 2, the terminal supports an uplink bandwidth BW2 that is less than or equal to the bandwidth of initial uplink carrier 2 and greater than or equal to the bandwidth of the initial uplink BWP of initial uplink carrier 2; and simultaneously, for initial uplink carrier 3, the terminal supports an uplink bandwidth BW3 that is less than or equal to the bandwidth of initial uplink carrier 3 and greater than or equal to the bandwidth of the initial uplink BWP of initial uplink carrier 3, then the terminal considers that it meets the conditions for camping in the first cell.

[0222] Beneficial effects: In this implementation, all initial uplink carriers must meet the condition of being "less than or equal to the bandwidth of the initial uplink carrier and greater than or equal to the bandwidth of the initial uplink BWP of the initial uplink carrier" to be considered as meeting the conditions for camping in the first cell. This implementation places high demands on terminal capabilities, but since all carrier resources are available, it can improve the flexibility of terminal access to the first cell.

[0223] 4. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the anchored initial downlink carrier in the initial downlink carrier configured in the downlink configuration information, and is greater than or equal to the bandwidth of the initial downlink BWP of the anchored initial downlink carrier.

[0224] For example, in one implementation, the network-side device explicitly indicates in the first configuration information which initial downlink carrier configuration is the anchored initial downlink carrier configuration; in another implementation, the network-side device only explicitly indicates in the first configuration information: non-anchored initial downlink carrier configuration, thus not displaying the carrier configuration indicated as non-anchored initial downlink carrier, i.e., the anchored initial downlink carrier configuration.

[0225] Beneficial effects: Through this implementation method, the downlink bandwidth supported by the terminal and the anchored initial downlink carrier only need to meet the bandwidth conditions for the terminal to camp in the first cell to determine that the conditions for camping in the first cell are met. The requirements for terminal capabilities are not high, which can reduce the complexity of the terminal.

[0226] 5. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the anchored initial uplink carrier in the initial uplink carrier configured by the at least one uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP anchored to the initial uplink carrier.

[0227] For example, in one implementation, the network-side device explicitly indicates in the first configuration information which initial uplink carrier configuration is anchored to the initial uplink carrier; in another implementation, the network-side device only explicitly indicates in the first configuration information: non-anchored initial uplink carrier configuration, thus not displaying the carrier configuration indicated as non-anchored initial uplink carrier, i.e., the configuration anchored initial uplink carrier.

[0228] Beneficial effects: Through this implementation method, the uplink bandwidth supported by the terminal and the anchored initial uplink carrier only need to meet the bandwidth conditions for the terminal to camp in the first cell to determine that the conditions for camping in the first cell are met. The requirements for terminal capabilities are not high, and the complexity of the terminal can be reduced.

[0229] It should be noted that the terms "non-anchored cell" or "non-anchored carrier" used in this application can be understood as terms used in different scenarios. However, in this invention, these terms are mainly used to describe non-anchored resources corresponding to the concepts of anchored cell or anchored carrier. Furthermore, to simplify the description of this application, some embodiments do not use specific anchored / non-anchored cells or anchored / non-anchored carriers as examples, but only use terms such as anchored resources or non-anchored resources to describe the method. The anchored resources or non-anchored resources can be frequency-domain related resources such as cells, carriers, carrier combinations, BWPs, BWP combinations, frequency bands, frequency band combinations, etc. The anchored / non-anchored terms used in this application can also be replaced by terms with similar or identical meanings such as Primary / Secondary, Primary / Secondary, Major / Minor. This application does not impose specific limitations in this regard.

[0230] 6. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier associated with the characteristics of the terminal in the initial downlink carrier configured by the at least one downlink configuration information, and is greater than or equal to the bandwidth of the initial downlink BWP of the initial downlink carrier.

[0231] For example, the initial downlink carrier associated with a characteristic of the terminal is the initial downlink carrier associated with the downlink characteristics of the terminal. As another example, the initial downlink carrier associated with a characteristic of the terminal is one in which the associated characteristic set includes the initial downlink carriers of the downlink characteristics of the terminal.

[0232] Optionally, the downlink configuration information includes a set of features associated with the initial downlink carrier configured in the downlink configuration information. The set of features associated with the initial downlink carrier configured in the downlink configuration information includes a set of features supported by the initial downlink carrier.

[0233] Optionally, the downlink characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal. The type of the terminal includes, but is not limited to, RedCap UE or VSAT UE. For example, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with the terminal type, such as VSAT. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with VSAT UE. Furthermore, the capabilities supported by the terminal include, but are not limited to, supporting RedCap, supporting NTN, or supporting Multimedia Broadcast Service (MBS), etc. Furthermore, the parameters supported by the terminal include, but are not limited to, the uplink / downlink channel bandwidth supported by the terminal, the terminal's power consumption status (e.g., high / medium / low battery, such as battery percentage), and the number of Tx / Rx antennas of the terminal. Furthermore, the services supported by the terminal include, but are not limited to, eMBB, URLLC, or MBS, etc. For example, when a terminal determines that it meets the conditions for camping on the first cell, the third or fourth uplink frequency domain resource element used is associated with a service supported by the terminal, such as URLLC. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with URLLC.

[0234] Beneficial effects: Through this implementation method, the downlink bandwidth supported by the terminal and the initial downlink carrier associated with the characteristics of the terminal only need to meet the bandwidth condition for the terminal to camp in the first cell to determine that the condition for camping in the first cell is met. The requirements for terminal capabilities are not high, and the complexity of the terminal can be reduced.

[0235] 7. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier associated with the characteristics of the terminal in the at least one uplink configuration information configured, and is greater than or equal to the bandwidth of the initial uplink BWP of the initial uplink carrier. For example, the initial uplink carrier associated with the characteristics of the terminal is the initial uplink carrier associated with the uplink characteristics of the terminal.

[0236] For example, the initial uplink carrier associated with a characteristic of the terminal is the initial uplink carrier associated with the uplink characteristic of the terminal. As another example, the initial uplink carrier associated with a characteristic of the terminal is one where the associated characteristic set includes the initial uplink carriers of the uplink characteristics of the terminal.

[0237] Optionally, the uplink configuration information includes a set of features associated with the initial uplink carrier configured in the uplink configuration information, which includes a set of features supported by the initial uplink carrier.

[0238] Optionally, the uplink characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal. The type of the terminal includes, but is not limited to, RedCap UE or VSAT UE. For example, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with the terminal type, such as VSAT. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with VSAT UE. Furthermore, the capabilities supported by the terminal include, but are not limited to, supporting RedCap, supporting NTN, or supporting Multimedia Broadcast Service (MBS), etc. Furthermore, the parameters supported by the terminal include, but are not limited to, the uplink / uplink channel bandwidth supported by the terminal, the terminal's power consumption status (e.g., high / medium / low battery, such as battery percentage), and the number of Tx / Rx antennas of the terminal. Furthermore, the services supported by the terminal include, but are not limited to, eMBB, URLLC, or MBS, etc. For example, when a terminal determines that it meets the conditions for camping on the first cell, the third or fourth uplink frequency domain resource element used is associated with a service supported by the terminal, such as URLLC. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with URLLC.

[0239] Beneficial effects: Through this implementation method, the uplink bandwidth supported by the terminal and the initial uplink carrier associated with the characteristics of the terminal only need to meet the bandwidth condition for the terminal to camp in the first cell to determine that the condition for camping in the first cell is met. The requirements for terminal capabilities are not high, and the complexity of the terminal can be reduced.

[0240] 8. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier with the largest bandwidth among the initial uplink carriers configured by the at least one uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP anchored to the initial uplink carrier.

[0241] For example, the terminal supports an uplink bandwidth of 40MHz. The at least one uplink configuration information indicates two initial uplink carriers. Specifically, initial uplink carrier 1 has a bandwidth of 50MHz and an initial uplink BWP of 5MHz; initial uplink carrier 2 has a bandwidth of 20MHz and an initial uplink BWP of 20MHz. It is evident that the initial uplink carrier with the largest bandwidth is initial uplink carrier 1. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier 1, and greater than or equal to the bandwidth of the initial uplink BWP of the initial uplink carrier 1. Therefore, the terminal meets the condition that it can camp on the first cell.

[0242] Beneficial effects: Through this implementation method, the uplink bandwidth supported by the terminal and the initial uplink carrier with the largest bandwidth are only required to meet the bandwidth conditions for the terminal to camp in the first cell. This determines that the conditions for camping in the first cell are met, which does not place high demands on the terminal's capabilities and can reduce the complexity of the terminal.

[0243] Step 2-2:

[0244] Based on the first configuration information, if a second condition is met, the terminal determines that it does not meet the conditions for camping on the first cell; wherein the second condition includes at least one of the following:

[0245] 1. The downlink bandwidth supported by the terminal does not meet the following conditions: less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier.

[0246] 2. For each of the initial uplink carriers configured in the at least one uplink configuration information, the uplink bandwidth supported by the terminal does not have an uplink bandwidth that satisfies the following conditions: less than or equal to the bandwidth of each initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP of each initial uplink carrier.

[0247] In other words, there is no initial uplink carrier that supports uplink bandwidth such that the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of each initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP of each initial uplink carrier. For example, the uplink bandwidth supported by the terminal is 40MHz. The at least one uplink configuration information indicates two initial uplink carriers. Among them, the bandwidth of initial uplink carrier 1 is 10MHz, and the initial uplink BWP of the initial uplink carrier is 5MHz; the bandwidth of initial uplink carrier 2 is 20MHz, and the initial uplink BWP of initial uplink carrier 2 is 20MHz. It can be seen that the uplink bandwidth supported by the terminal does not meet the bandwidth requirement of any initial uplink carrier, therefore the terminal cannot camp on the first cell.

[0248] 3. For each of the initial uplink carriers among at least a portion of the initial uplink carriers configured by the at least one uplink configuration information, the uplink bandwidth supported by the terminal does not have an uplink bandwidth that satisfies the following condition: less than or equal to the bandwidth of each initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP of each initial uplink carrier.

[0249] 4. The downlink bandwidth supported by the terminal does not meet the following conditions: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the anchored initial downlink carrier in the initial downlink carrier configured in the downlink configuration information, and is greater than or equal to the bandwidth of the initial downlink BWP of the anchored initial downlink carrier.

[0250] 5. The uplink bandwidth supported by the terminal does not meet the following conditions: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the anchored initial uplink carrier in the initial uplink carrier configured by the at least one uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP of the anchored initial uplink carrier.

[0251] 6. The uplink bandwidth supported by the terminal does not exist that satisfies the following condition: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier associated with the terminal's characteristics in the initial downlink carrier configured by at least one downlink configuration information, and is greater than or equal to the bandwidth of the initial downlink BWP of the initial downlink carrier. For example, the initial downlink carrier associated with the terminal's characteristics is the initial downlink carrier associated with the terminal's downlink characteristics.

[0252] 7. The uplink bandwidth supported by the terminal does not exist that satisfies the following condition: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier associated with the terminal's characteristics among the initial uplink carriers configured in the at least one uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP of the initial uplink carrier. For example, the initial uplink carrier associated with the terminal's characteristics is the initial uplink carrier associated with the terminal's uplink characteristics.

[0253] 8. The uplink bandwidth supported by the terminal does not meet the following conditions: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier with the largest bandwidth among the initial uplink carriers configured by the at least one uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP anchored to the initial uplink carrier.

[0254] It should be noted that the second condition and the first condition mentioned above are positive and negative conditions, and they can be referred to each other. In order to avoid repetition, this application will not repeat the relevant terms and beneficial effects involved in the second condition, but can refer to the relevant content involving the first condition.

[0255] Example 2:

[0256] In this embodiment, the first downlink frequency domain resource unit is the initial downlink carrier, the second downlink frequency domain resource unit is the initial downlink BWP, the first uplink frequency domain resource unit is the initial uplink carrier, and the second uplink frequency domain resource unit is the initial uplink BWP.

[0257] For example, in this embodiment, the deployment scenario is as follows: the first cell supports multiple initial downlink carriers and multiple initial uplink carriers for random access, and each carrier supports a single initial BWP. For example, the first cell is an SCMC cell.

[0258] In this embodiment, the terminal can determine the campability of the first cell by following these steps:

[0259] Step 1:

[0260] The terminal receives first configuration information from the first cell, the first configuration information including:

[0261] At least one downlink configuration information, the downlink configuration information including:

[0262] The bandwidth of the initial downlink carrier;

[0263] The initial downlink BWP bandwidth;

[0264] At least one uplink configuration information, the uplink configuration information including:

[0265] The bandwidth of the initial uplink carrier;

[0266] The initial uplink bandwidth of the BWP.

[0267] For example, a network-side device can configure one or more downlink configuration information entries, each carrying carrier configuration information for an initial downlink carrier. The carrier configuration information for the initial downlink carrier includes the bandwidth of the initial downlink carrier and the bandwidth of the initial downlink BWP on the initial downlink carrier. Alternatively, the network-side device can configure a downlink configuration information entry carrying a list of carrier configuration information entries containing initial downlink carriers, where the list contains carrier configuration information for one or more initial downlink carriers. The carrier configuration information for the initial downlink carrier includes the bandwidth of the initial downlink carrier and the bandwidth of the initial downlink BWP on the initial downlink carrier.

[0268] For example, a network-side device can configure one or more uplink configuration messages, each carrying carrier configuration information for an initial uplink carrier. The carrier configuration information for the initial uplink carrier includes the bandwidth of the initial uplink carrier and the bandwidth of the initial uplink BWP on the initial uplink carrier. Alternatively, the network-side device can configure an uplink configuration message carrying a list of carrier configuration information containing initial uplink carriers, where the list contains carrier configuration information for one or more initial uplink carriers. The carrier configuration information for the initial uplink carrier includes the bandwidth of the initial uplink carrier and the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0269] Step 2:

[0270] The terminal determines that it meets the conditions for being able to camp on the first cell or determines that it does not meet the conditions for being able to camp on the first cell.

[0271] Step 2-1:

[0272] Based on the first configuration information, the terminal determines that it meets the conditions for camping on the first cell if a first condition is satisfied; wherein the first condition includes at least one of the following:

[0273] 1. For at least a portion of the initial downlink carriers and their associated initial uplink carriers among all the initial downlink carriers configured by the at least one downlink configuration information, the following condition is met:

[0274] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier;

[0275] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0276] For example, an initial downlink carrier may be associated with one or more initial uplink carriers. For instance, the base station configures initial downlink carrier 1 to be associated with initial uplink carrier 1, and initial downlink carrier 2 to be associated with initial uplink carrier 2 / initial uplink carrier 3. If the UE has a supported downlink bandwidth that is less than or equal to the bandwidth of initial downlink carrier 2, and greater than or equal to the initial downlink bandwidth of initial downlink carrier 2; simultaneously, the UE has a supported uplink bandwidth that is less than or equal to the bandwidth of initial uplink carrier 3, and greater than or equal to the initial uplink bandwidth of initial uplink carrier 3, then the UE is determined to meet the conditions for camping in the first cell. In other words, the UE's supported downlink bandwidth and initial downlink carrier 2, as well as the UE's supported uplink bandwidth and the initial uplink carrier 3 associated with initial downlink carrier 2, satisfy the uplink and downlink bandwidth conditions for the terminal to camp in the first cell.

[0277] Beneficial effects: With this implementation method, as long as there is at least one pair of associated uplink and downlink carriers, the bandwidth capability supported by the UE is sufficient to meet the requirements, that is, the conditions for camping in the first cell are met. The requirements for terminal capability are not high, which helps to reduce the complexity of the terminal.

[0278] 2. For each initial downlink carrier and its associated initial uplink carrier among all initial downlink carriers configured by the at least one downlink configuration information, the following conditions are met:

[0279] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier;

[0280] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0281] Beneficial effects: In this implementation, each initial uplink carrier and its associated initial downlink carrier must meet the condition of being "less than or equal to the bandwidth of the initial uplink carrier and greater than or equal to the bandwidth of the initial uplink BWP of the initial uplink carrier" to determine whether the conditions for camping in the first cell are met. This implementation places high demands on terminal capabilities, but since all carrier resources are available, it can improve the flexibility of terminal access to the first cell.

[0282] 3. For the anchored initial downlink carrier and its associated anchored initial uplink carrier in the initial downlink carrier configured by the at least one downlink configuration information, the following condition is met:

[0283] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier;

[0284] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0285] Beneficial effects: Through this implementation method, the uplink / downlink bandwidth and anchored initial uplink / downlink carrier supported by the terminal only need to meet the bandwidth conditions for the terminal to camp in the first cell to determine that the conditions for camping in the first cell are met. The requirements for terminal capabilities are not high, and the complexity of the terminal can be reduced.

[0286] It should be noted that the terms "non-anchored cell" or "non-anchored carrier" used in this application can be understood as terms used in different scenarios. However, in this invention, these terms are mainly used to describe non-anchored resources corresponding to the concepts of anchored cell or anchored carrier. Furthermore, to simplify the description of this application, some embodiments do not use specific anchored / non-anchored cells or anchored / non-anchored carriers as examples, but only use terms such as anchored resources or non-anchored resources to describe the method. The anchored resources or non-anchored resources can be frequency-domain related resources such as cells, carriers, carrier combinations, BWPs, BWP combinations, frequency bands, frequency band combinations, etc. The anchored / non-anchored terms used in this application can also be replaced by terms with similar or identical meanings such as Primary / Secondary, Primary / Secondary, Major / Minor. This application does not impose specific limitations in this regard.

[0287] 4. For the initial downlink carrier associated with the characteristics of the terminal and its associated initial uplink carrier in the initial downlink carrier configured by the at least one downlink configuration information, the following conditions are met:

[0288] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier;

[0289] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0290] For example, the initial downlink carrier associated with a characteristic of the terminal is the initial downlink carrier associated with the downlink characteristics of the terminal. As another example, the initial downlink carrier associated with a characteristic of the terminal is one in which the associated characteristic set includes the initial downlink carriers of the downlink characteristics of the terminal.

[0291] Optionally, the at least one uplink configuration information includes at least one of the following:

[0292] The set of features associated with the initial uplink carrier configured by the at least one uplink configuration information;

[0293] The set of features associated with the initial uplink BWP configured by at least one uplink configuration information.

[0294] Optionally, the at least one downlink configuration information includes at least one of the following:

[0295] The set of features associated with the initial downlink carrier configured by the at least one downlink configuration information;

[0296] The set of features associated with the initial downlink BWP configured by at least one downlink configuration information.

[0297] Optionally, the feature set associated with the initial downlink carrier configured by the at least one downlink configuration information includes: a set of features supported by the initial downlink carrier. The feature set associated with the initial downlink BWP configured by the downlink configuration information includes: a set of features supported by the initial downlink BWP. The feature set associated with the initial uplink carrier configured by the at least one uplink configuration information includes: a set of features supported by the initial uplink carrier. The feature set associated with the initial uplink BWP configured by the uplink configuration information includes: a set of features supported by the initial uplink BWP.

[0298] Optionally, the downlink characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal. The type of the terminal includes, but is not limited to, RedCap UE or VSAT UE. For example, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with the terminal type, such as VSAT. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with VSAT UE. Furthermore, the capabilities supported by the terminal include, but are not limited to, supporting RedCap, supporting NTN, or supporting Multimedia Broadcast Service (MBS), etc. Furthermore, the parameters supported by the terminal include, but are not limited to, the uplink / downlink channel bandwidth supported by the terminal, the terminal's power consumption status (e.g., high / medium / low battery, such as battery percentage), and the number of Tx / Rx antennas of the terminal. Furthermore, the services supported by the terminal include, but are not limited to, eMBB, URLLC, or MBS, etc. For example, when a terminal determines that it meets the conditions for camping on the first cell, the third or fourth uplink frequency domain resource element used is associated with a service supported by the terminal, such as URLLC. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with URLLC.

[0299] Beneficial effects: Through this implementation method, the uplink / downlink bandwidth supported by the terminal and the initial uplink / downlink carrier associated with the characteristics of the terminal are determined to meet the conditions for the terminal to camp in the first cell only if the bandwidth conditions for the terminal to camp in the first cell are met. This method does not place high demands on the terminal's capabilities and can reduce the complexity of the terminal.

[0300] 5. For the initial downlink carrier with the largest bandwidth and its associated initial uplink carrier among the initial downlink carriers configured by the at least one downlink configuration information, the following condition must be met:

[0301] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier;

[0302] The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0303] Beneficial effects: Through this implementation method, the downlink bandwidth supported by the terminal and the initial downlink carrier with the largest bandwidth, as well as the uplink bandwidth supported by the terminal and the initial uplink carrier associated with the initial downlink carrier with the largest bandwidth, are determined to meet the conditions for the terminal to camp in the first cell only if the bandwidth conditions for the terminal to camp in the first cell are met. This reduces the requirements on the terminal's capabilities and can reduce the complexity of the terminal.

[0304] Of course, the above conditions are merely examples. In some embodiments, the decision on déjà vu can also be based on a specific initial uplink carrier and its associated initial downlink carrier among the initial uplink carriers configured with the at least one uplink configuration information. For example, the specific initial uplink carrier could be the initial uplink carrier with the largest bandwidth or the initial uplink carrier associated with the characteristics of the terminal. This embodiment does not specifically limit this.

[0305] Step 2-2:

[0306] Based on the first configuration information, if a second condition is met, the terminal determines that it does not meet the conditions for camping on the first cell; wherein the second condition includes at least one of the following:

[0307] 1. For each initial downlink carrier and its associated initial uplink carrier among all initial downlink carriers configured by the at least one downlink configuration information, the following condition is not met:

[0308] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier; the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0309] 2. For at least a portion of the initial downlink carriers and their associated initial uplink carriers among all the initial downlink carriers configured by the at least one downlink configuration information, the following condition is not met:

[0310] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier; the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0311] 3. For the anchored initial downlink carrier and its associated anchored initial uplink carrier in the initial downlink carrier configured by the at least one downlink configuration information, the following condition is not met:

[0312] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier; the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0313] 4. For the initial downlink carrier associated with the characteristics of the terminal and its associated initial uplink carrier in the initial downlink carrier configured by the at least one downlink configuration information, the following condition is not met:

[0314] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier; the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0315] 5. For the initial downlink carrier with the largest bandwidth among the initial downlink carriers configured in the at least one downlink configuration information and its associated initial uplink carrier, the following condition is not met:

[0316] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier, and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier; the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier, and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier.

[0317] It should be noted that the second condition and the first condition mentioned above are positive and negative conditions, and they can be referred to each other. In order to avoid repetition, this application will not repeat the relevant terms and beneficial effects involved in the second condition, but can refer to the relevant content involving the first condition.

[0318] Example 3:

[0319] In this embodiment, the first downlink frequency domain resource unit is the initial downlink carrier, the second downlink frequency domain resource unit is the initial downlink BWP, the first uplink frequency domain resource unit is the initial uplink carrier, and the second uplink frequency domain resource unit is the initial uplink BWP.

[0320] For example, in this embodiment, the deployment scenario is as follows: the first cell supports one initial downlink carrier and one initial uplink carrier for random access, and each carrier supports one or more initial BWPs. For example, the first cell is an SCM-BWP cell.

[0321] In this embodiment, the terminal can determine the campability of the first cell by following these steps:

[0322] Step 1:

[0323] The terminal receives first configuration information from the first cell, the first configuration information including:

[0324] Downlink configuration information, which includes:

[0325] The bandwidth of the initial downlink carrier;

[0326] At least one initial downlink BWP bandwidth;

[0327] Uplink configuration information, which includes:

[0328] The bandwidth of the initial uplink carrier;

[0329] At least one initial uplink BWP bandwidth.

[0330] Step 2:

[0331] The terminal determines that it meets the conditions for being able to camp on the first cell or determines that it does not meet the conditions for being able to camp on the first cell.

[0332] Step 2-1:

[0333] Based on the first configuration information, the terminal determines that it meets the conditions for camping on the first cell if a first condition is satisfied; wherein the first condition includes at least one of the following:

[0334] 1. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and greater than or equal to the bandwidth of each initial downlink BWP in at least a portion of the at least one initial downlink BWP.

[0335] Beneficial effects: Through this implementation method, as long as the downlink bandwidth supported by the terminal has at least one downlink bandwidth that can meet the condition of "less than or equal to the bandwidth of the initial downlink carrier and greater than or equal to the bandwidth of the initial downlink BWP on the initial downlink carrier", it can be determined that the terminal meets the conditions for camping in the first cell. The requirements for the terminal's capabilities are not high, which helps to reduce the complexity of the terminal.

[0336] 2. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and greater than or equal to the bandwidth of each initial uplink BWP in at least a portion of the at least one initial uplink BWP.

[0337] Optionally, the aforementioned initial uplink carrier is associated with the aforementioned initial downlink carrier.

[0338] Optionally, the aforementioned initial downlink BWP is associated with the aforementioned initial uplink BWP.

[0339] Beneficial effects: Through this implementation method, as long as the uplink bandwidth supported by the terminal has at least one uplink bandwidth that can meet the condition of "less than or equal to the bandwidth of the initial uplink carrier and greater than or equal to the bandwidth of the initial uplink BWP on the initial uplink carrier", it can be determined that the terminal meets the conditions for camping in the first cell. The requirements for the terminal's capabilities are not high, which helps to reduce the complexity of the terminal.

[0340] 3. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and greater than or equal to the bandwidth of the initial downlink BWP with the smallest bandwidth among the at least one initial downlink BWP.

[0341] For example, if an initial downlink carrier is configured with two initial downlink BWPs, one with a bandwidth of 10MHz and the other with a bandwidth of 5MHz, then the terminal can be considered to meet the condition as long as the downlink bandwidth supported is greater than or equal to 5MHz.

[0342] Beneficial effects: Through this implementation method, the downlink bandwidth supported by the terminal and the initial downlink BWP with the minimum bandwidth only need to meet the bandwidth condition that the terminal can camp on the first cell to determine that the condition for camping on the first cell is met. The requirements for terminal capabilities are not high, and the complexity of the terminal can be reduced.

[0343] 4. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and greater than or equal to the bandwidth of the initial uplink BWP with the smallest bandwidth among the at least one initial uplink BWP.

[0344] For example, if an initial uplink carrier is configured with two initial uplink BWPs, one with a bandwidth of 10MHz and the other with a bandwidth of 5MHz, then the terminal can be considered to meet the condition as long as the uplink bandwidth it supports is greater than or equal to 5MHz.

[0345] Beneficial effects: Through this implementation method, the uplink bandwidth supported by the terminal and the initial uplink BWP with the minimum bandwidth only need to meet the bandwidth condition that the terminal can camp on the first cell to determine that the condition for camping on the first cell is met. The requirements for terminal capabilities are not high, which can reduce the complexity of the terminal.

[0346] 5. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and greater than or equal to the bandwidth of the anchored initial downlink BWP in the at least one initial downlink BWP.

[0347] For example, in one implementation, the network-side device explicitly indicates in the first configuration information which initial downlink BWP configuration is the anchored initial downlink BWP configuration; in another implementation, the network-side device only explicitly indicates in the first configuration information: non-anchored initial downlink BWP configuration, thus not displaying the BWP configuration indicated as non-anchored initial downlink BWP, i.e., the configuration anchored initial downlink BWP.

[0348] Beneficial effects: Through this implementation method, the downlink bandwidth supported by the terminal and the anchored initial downlink BWP only need to meet the bandwidth conditions for the terminal to camp in the first cell to determine that the conditions for camping in the first cell are met. The requirements for the terminal capability are not high, which can reduce the complexity of the terminal.

[0349] 6. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and greater than or equal to the bandwidth of the anchored initial uplink BWP in the at least one initial uplink BWP.

[0350] For example, in one implementation, the network-side device explicitly indicates in the first configuration information which initial uplink BWP configuration is anchored to the initial uplink BWP; in another implementation, the network-side device only explicitly indicates in the first configuration information: non-anchored initial uplink BWP configuration, thus not displaying the BWP configuration indicated as non-anchored initial uplink BWP, which is the configuration anchored to the initial uplink BWP.

[0351] Beneficial effects: Through this implementation method, the uplink bandwidth supported by the terminal and the anchored initial uplink BWP only need to meet the bandwidth conditions for the terminal to camp in the first cell to determine that the conditions for camping in the first cell are met. The requirements for terminal capabilities are not high, which can reduce the complexity of the terminal.

[0352] It should be noted that the terms "non-anchored cell" or "non-anchored carrier" used in this application can be understood as terms used in different scenarios. However, in this invention, these terms are mainly used to describe non-anchored resources corresponding to the concepts of anchored cell or anchored carrier. Furthermore, to simplify the description of this application, some embodiments do not use specific anchored / non-anchored cells or anchored / non-anchored carriers as examples, but only use terms such as anchored resources or non-anchored resources to describe the method. The anchored resources or non-anchored resources can be frequency-domain related resources such as cells, carriers, carrier combinations, BWPs, BWP combinations, frequency bands, frequency band combinations, etc. The anchored / non-anchored terms used in this application can also be replaced by terms with similar or identical meanings such as Primary / Secondary, Primary / Secondary, Major / Minor. This application does not impose specific limitations in this regard.

[0353] 7. The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and greater than or equal to the bandwidth of the initial downlink BWP associated with the characteristics of the terminal in the at least one initial downlink BWP.

[0354] For example, the initial downlink BWP associated with a characteristic of the terminal is the initial downlink BWP associated with the downlink characteristics of the terminal. As another example, the initial downlink BWP associated with a characteristic of the terminal is: the associated characteristic set includes the initial downlink BWP of the downlink characteristics of the terminal.

[0355] Optionally, the downlink configuration information includes the set of features associated with the initial downlink BWP configured in the downlink configuration information. The set of features associated with the initial downlink BWP configured in the downlink configuration information includes: a set of features supported by the initial downlink BWP.

[0356] Optionally, the downlink characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal. The type of the terminal includes, but is not limited to, RedCap UE or VSAT UE. For example, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with the terminal type, such as VSAT. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with VSAT UE. Furthermore, the capabilities supported by the terminal include, but are not limited to, supporting RedCap, supporting NTN, or supporting Multimedia Broadcast Service (MBS), etc. Furthermore, the parameters supported by the terminal include, but are not limited to, the uplink / downlink channel bandwidth supported by the terminal, the terminal's power consumption status (e.g., high / medium / low battery, such as battery percentage), and the number of Tx / Rx antennas of the terminal. Furthermore, the services supported by the terminal include, but are not limited to, eMBB, URLLC, or MBS, etc. For example, when a terminal determines that it meets the conditions for camping on the first cell, the third or fourth uplink frequency domain resource element used is associated with a service supported by the terminal, such as URLLC. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with URLLC.

[0357] For example, the network-side equipment configures two initial downlink BWPs for the initial downlink carrier, such as initial downlink BWP1 and initial downlink BWP2. The downlink configuration information indicates the associated set of features. For example, initial downlink BWP1 is configured for RedCap UEs and IoT UEs, while initial downlink BWP2 is configured for XR UEs and regular UEs. Then, based on the configuration of initial downlink BWP1, a RedCap UE or IoT UE can further determine whether it meets the first cell camping conditions by using the bandwidth of initial downlink BWP1.

[0358] Beneficial effects: Through this implementation method, the initial downlink BWP associated with the downlink bandwidth supported by the terminal and the characteristics of the terminal is determined to meet the conditions for the terminal to camp in the first cell only if the bandwidth condition for the terminal to camp in the first cell is met. This method does not place high demands on the terminal's capabilities and can reduce the complexity of the terminal.

[0359] 8. The uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and greater than or equal to the bandwidth of the initial uplink BWP associated with the characteristics of the terminal in the at least one initial uplink BWP.

[0360] For example, the initial uplink BWP associated with a characteristic of the terminal is the initial uplink BWP associated with the uplink characteristics of the terminal. As another example, the initial uplink BWP associated with a characteristic of the terminal is: the associated characteristic set includes the initial uplink BWPs of the uplink characteristics of the terminal.

[0361] Optionally, the uplink configuration information includes the set of features associated with the initial uplink BWP configured in the uplink configuration information. The set of features associated with the initial uplink BWP configured in the uplink configuration information includes: a set of features supported by the initial uplink BWP.

[0362] Optionally, the uplink characteristics of the terminal include at least one of the following: the type of the terminal, the capabilities supported by the terminal, the parameters supported by the terminal, and the services supported by the terminal. The type of the terminal includes, but is not limited to, RedCap UE or VSAT UE. For example, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with the terminal type, such as VSAT. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource unit used by the terminal when determining that it meets the conditions for camping in the first cell is associated with VSAT UE. Furthermore, the capabilities supported by the terminal include, but are not limited to, supporting RedCap, supporting NTN, or supporting Multimedia Broadcast Service (MBS), etc. Furthermore, the parameters supported by the terminal include, but are not limited to, the uplink / uplink channel bandwidth supported by the terminal, the terminal's power consumption status (e.g., high / medium / low battery, such as battery percentage), and the number of Tx / Rx antennas of the terminal. Furthermore, the services supported by the terminal include, but are not limited to, eMBB, URLLC, or MBS, etc. For example, when a terminal determines that it meets the conditions for camping on the first cell, the third or fourth uplink frequency domain resource element used is associated with a service supported by the terminal, such as URLLC. Therefore, when the UE's terminal type is VSAT UE, the third or fourth uplink frequency domain resource element used by the terminal when determining that it meets the conditions for camping on the first cell is associated with URLLC.

[0363] Beneficial effects: Through this implementation method, the initial uplink BWP associated with the uplink bandwidth supported by the terminal and the characteristics of the terminal is determined to meet the conditions for the terminal to camp in the first cell only if the bandwidth condition for the terminal to camp in the first cell is met. This method does not place high demands on the terminal's capabilities and can reduce the complexity of the terminal.

[0364] It should be noted that in NR technology, when the network configures both regular BWP and RedCap BWP, from the terminal's perspective, whether it's a regular UE or a RedCap UE, the network-side configuration shows that the terminal only has one initial uplink carrier (excluding SUL), one initial downlink carrier, one initial uplink BWP, and one initial BWP downlink. A regular UE can use the regular BWP, and a RedCap UE can use the RedCap BWP, but from the network's perspective, it appears that two different initial uplink BWPs or two different initial downlink BWPs are configured. Therefore, configuring two different initial BWPs is necessary for both regular and RedCap UEs. If more UE types are considered in the future, even more different initial BWPs may need to be configured, which is potentially unnecessary. In this embodiment, the network-side equipment does not need to configure more initial BWPs for different purposes based on terminal characteristics, terminal capabilities, and services in different future scenarios. Instead, a feature set can be designed, which is associated with the initial BWP or initial carrier. The terminal determines whether an initial BWP or initial carrier meets the requirements for first-cell camping based on its own characteristics, reducing the configuration complexity of BWPs.

[0365] Step 2-2:

[0366] Based on the first configuration information, if a second condition is met, the terminal determines that it does not meet the conditions for camping on the first cell; wherein the second condition includes at least one of the following:

[0367] 1. The downlink bandwidth supported by the terminal does not meet the following conditions: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and is greater than or equal to the bandwidth of each initial downlink BWP in at least a portion of the initial downlink BWPs in the at least one initial downlink BWP.

[0368] 2. The downlink bandwidth supported by the terminal does not have an uplink bandwidth that meets the following conditions: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and is greater than or equal to the bandwidth of each initial uplink BWP in at least a portion of the at least one initial uplink BWP.

[0369] 3. The downlink bandwidth supported by the terminal does not meet the following conditions: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and is greater than or equal to the bandwidth of the initial downlink BWP with the smallest bandwidth among the at least one initial downlink BWP.

[0370] 4. The downlink bandwidth supported by the terminal does not have an uplink bandwidth that meets the following conditions: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP with the smallest bandwidth among the at least one initial uplink BWP.

[0371] 5. The downlink bandwidth supported by the terminal does not have an uplink bandwidth that meets the following conditions: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and is greater than or equal to the bandwidth of the anchored initial downlink BWP in the at least one initial downlink BWP.

[0372] 6. The downlink bandwidth supported by the terminal does not meet the following conditions: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and is greater than or equal to the bandwidth of the anchored initial uplink BWP in the at least one initial uplink BWP.

[0373] 7. The downlink bandwidth supported by the terminal does not have an uplink bandwidth that meets the following conditions: the downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial downlink carrier configured in the downlink configuration information, and is greater than or equal to the bandwidth of the initial downlink BWP associated with the characteristics of the terminal in the at least one initial downlink BWP.

[0374] 8. The downlink bandwidth supported by the terminal does not meet the following conditions: the uplink bandwidth supported by the terminal is less than or equal to the bandwidth of the initial uplink carrier configured in the uplink configuration information, and is greater than or equal to the bandwidth of the initial uplink BWP associated with the characteristics of the terminal in the at least one initial uplink BWP.

[0375] It should be noted that the second condition and the first condition mentioned above are positive and negative conditions, and they can be referred to each other. In order to avoid repetition, this application will not repeat the relevant terms and beneficial effects involved in the second condition, but can refer to the relevant content involving the first condition.

[0376] Example 4:

[0377] In this embodiment, the first downlink frequency domain resource unit is an initial downlink carrier set, and the first uplink frequency domain resource unit is an initial uplink carrier set. The carrier set can be understood as a set of multiple aggregated carriers. For example, in a downlink frequency band with a bandwidth of 20MHz at 800MHz, two initial downlink carriers can be configured: initial downlink carrier 1 with a bandwidth of 5MHz and initial downlink carrier 2 with a bandwidth of 10MHz. Initial downlink carrier 1 and initial downlink carrier 2 can form an initial downlink carrier set.

[0378] The bandwidth of the initial downlink carrier set is one of the following:

[0379] 1. The sum of the bandwidths of the carriers included in the initial downlink carrier set.

[0380] For example, in the above example, the bandwidth of the initial downlink carrier set is 5MHz + 10MHz, which is 15MHz.

[0381] 2. The bandwidth from the lowest frequency point to the highest frequency point among the carriers included in the initial downlink carrier set.

[0382] For example, in the above example, the first carrier is located in the 5MHz bandwidth of 1-6MHz within the 20MHz downlink band, and the second carrier is located in the 10MHz bandwidth of 9-19MHz within the 20MHz downlink band. Therefore, the bandwidth of the initial downlink carrier set is the bandwidth from the lowest frequency point to the highest frequency point, i.e., 19MHz - 1MHz = 18MHz.

[0383] It should be noted that the bandwidth decision conditions originally applied to a single carrier as described in Examples 1 to 3 can be extended to the residency decision of cells supporting an initial downlink carrier set or an initial uplink carrier set. The difference is that the carrier bandwidth needs to be replaced with the bandwidth of the carrier set. To avoid repetition, this will not be elaborated further here.

[0384] Example 5:

[0385] In this embodiment, the second downlink frequency domain resource unit is an initial downlink BWP set, and the second uplink frequency domain resource unit is an initial uplink BWP set. The BWP set can be understood as a set unit composed of multiple aggregated BWPs. For example, in a 20MHz bandwidth downlink frequency band at 800MHz, two initial downlink BWPs can be configured: initial downlink BWP1 with a bandwidth of 5MHz and initial downlink BWP2 with a bandwidth of 10MHz. Initial downlink BWP1 and initial downlink BWP2 can form an initial downlink BWP set.

[0386] The bandwidth of the initial downlink BWP set is one of the following:

[0387] 1. The sum of the bandwidths of the BWPs included in the initial downlink BWP set.

[0388] For example, in the above example, the bandwidth of the initial downlink BWP set is 5MHz + 10MHz, which is 15MHz.

[0389] 2. The bandwidth from the lowest frequency point to the highest frequency point in the BWPs included in the initial downlink BWP set.

[0390] For example, in the above example, the first BWP is located in the 5MHz bandwidth of 1-6MHz within the downlink band of this 20MHz bandwidth, and the second BWP is located in the 10MHz bandwidth of 9-19MHz within the downlink band of this 20MHz bandwidth. Therefore, the bandwidth of the initial downlink BWP set is the bandwidth from the lowest frequency point to the highest frequency point, that is, 19MHz-1MHz=18MHz.

[0391] It should be noted that the bandwidth decision conditions originally applied to a single BWP described in Examples 1 to 3 can be extended to the residency decision of cells supporting an initial downlink BWP set or an initial uplink BWP set. The difference is that the bandwidth of the BWP needs to be replaced with the bandwidth of the BWP set. To avoid repetition, this will not be elaborated further here.

[0392] The cell-hosting method provided in this application can be executed by a cell-hosting device. This application uses a cell-hosting device executing the cell-hosting method as an example to illustrate the cell-hosting device provided in this application.

[0393] This application provides a cell camping device. As an example, the cell camping device can be a communication device or a component of a communication device, such as a chip. The communication device can be a terminal, a network-side device, or a server, etc. For example, the terminal can be, but is not limited to, the type of terminal 11 listed above, and the network-side device can be, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

[0394] The cell-based device includes a receiving module, a transmitting module, and a processing module. These modules can be implemented in software or hardware. When implemented in hardware, the processing module can be implemented by a processor. For example, the processor can include general-purpose processors, special-purpose processors, such as a Central Processing Unit (CPU), microprocessor, Digital Signal Processor (DSP), Artificial Intelligence (AI) processor, Graphics Processing Unit (GPU), Application Specific Integrated Circuit (ASIC), Network Processor (NP), Field Programmable Gate Array (FPGA), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: transceiver, pins, circuits, bus, radio frequency unit, etc.

[0402] The uplink bandwidth supported by the terminal is greater than or equal to the bandwidth of the fourth uplink frequency domain resource unit, and the fourth uplink frequency domain resource unit includes at least one of the following: any second uplink frequency domain resource unit in a portion of the at least one second uplink frequency domain resource unit, any second uplink frequency domain resource unit in the at least one second uplink frequency domain resource unit, and a specific second uplink frequency domain resource unit in the at least one second uplink frequency domain resource unit.

[0403] The downlink bandwidth supported by the terminal is less than or equal to the bandwidth of the third downlink frequency domain resource unit, wherein the third downlink frequency domain resource unit includes at least one of the following: any first downlink frequency domain resource unit in a portion of the at least one first downlink frequency domain resource unit, any first downlink frequency domain resource unit in the at least one first downlink frequency domain resource unit, or the bandwidth of a specific first downlink frequency domain resource unit in the at least one first downlink frequency domain resource unit.
