Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and particularly to a method for determining a threshold in contention-free random access (CFRA) and a device / memory medium / apparatus.

Background Art

[0002] In a wireless network system, a UE (User Equipment) usually needs to execute a CFRA (Contention-Free Random access) process based on an RSRP (Reference Signal Received Power) threshold.

[0003] In related technologies, when a UE triggers CFRA, if an RSRP threshold is set in the CFRA configuration, the CFRA process is executed based on the RSRP threshold in the CFRA configuration; if no RSRP threshold is set in the CFRA configuration, the CFRA process can be executed based on the RSRP threshold in the CBRA (Contention-based Random access) configuration.

[0004] However, when a UE executes a CFRA process based on the RSRP threshold in the CBRA configuration, if there are multiple CBRA configurations corresponding to the UE, the UE cannot determine specifically which RSRP threshold of the CBRA configuration to select to execute the CFRA process.

[0021] Hereinafter, with reference to the drawings, a method, apparatus, user equipment, network-side device, and storage medium for determining a threshold in a CFRA provided by an embodiment of the present disclosure will be described in detail.

[0022] FIG. 1 is a schematic flowchart of a method for determining a threshold in a CFRA provided by an embodiment of the present disclosure. The method is executed by a UE. As shown in FIG. 1, the method for determining a threshold in the CFRA may include the following steps.

[0023] In step 101, obtain a CBRA setting transmitted from a network-side device, where the CBRA setting includes at least one of a CBRA setting of a first release and a CBRA setting of a second release, and the first release precedes the second release.

[0024] In addition, in one embodiment of the present disclosure, a UE may refer to a device that provides voice and / or data connections to a user. The terminal device can communicate with one or more core networks via a Radio Access Network (RAN). The UE may be an Internet of Things (IoT) terminal. For example, it may be a sensor device, a mobile phone (also called a "cellular" phone), or a computer with an IoT terminal, such as a fixed, portable, pocket-sized, handheld, computer-integrated, or in-vehicle device. For example, it may be a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, the UE may be a device of an unmanned aerial vehicle. Alternatively, the UE may be an in-vehicle device. For example, it may be an electronic control unit having a wireless communication function, or a wireless communication device for externally attaching an electronic control unit. Or, the UE may be a roadside device, such as a street lamp, a traffic signal, or other roadside devices having a wireless communication function.

[0025] In one embodiment of the present disclosure, the first release can include at least one release, one release in the first release can correspond to at least one CBRA setting, the second release can include at least one release, and one release in the second release can correspond to at least one CBRA setting. Exemplarily, in one embodiment of the present disclosure, the first release may include Release-15 and / or Release-16, and the second release may include Release-17.

[0026] In addition, in one embodiment of the present disclosure, each CBRA setting of the second release can correspond to a combination of one or more characteristics. Here, the combination of characteristics can include a combination of one or more characteristics among Redcap (Reduced Capability), SDT (Small Data Transmission), Slice (network slice), and CE (Coverage Enhancement) characteristics.

[0027] Also, in one embodiment of the present disclosure, the relationship between the CBRA setting of the first release and the CBRA setting of the second release can include at least one of the following: the same RSRP threshold as that in the CBRA setting of the first release is individually set in the CBRA setting of the second release; a different RSRP threshold from that in the CBRA setting of the first release is individually set in the CBRA setting of the second release; no RSRP threshold is set in the CBRA setting of the second release, and the RSRP threshold in the CBRA setting of the first release is reused.

[0028] Here, in one embodiment of the present disclosure, the above RSRP threshold may include at least one of a SUL (Supplementary Uplink) selection threshold (e.g., rsrp - ThresholdSSB - SUL) and an SSB (Synchronization Signal Block) selection threshold (e.g., RSRP - ThresholdSSB, and / or msgA - RSRP - ThresholdSSB).

[0029] Furthermore, in one embodiment of the present disclosure, the above CBRA setting may include at least one of a two - step CBRA setting and a four - step CBRA setting.

[0030] Also, in one embodiment of the present disclosure, the UE obtaining the CBRA setting transmitted from the network - side device may include obtaining the CBRA setting transmitted by the network - side device via a system message.

[0031] Here, in one embodiment of the present disclosure, the above system message may be any system information transmitted from the network - side device. For example, the system information may be SIB (System Information Block) x, where x is a positive integer, and the SIB x may be an existing system message, a system message that will occur in the future, or a newly defined system message. Exemplarily, in one embodiment of the present disclosure, the SIB x may be the existing SIB 1.

[0032] Furthermore, in one embodiment of the present disclosure, the names of the fields carrying the CBRA setting of the first release and the CBRA setting of the second release may be the same. Also, when the names of the fields carrying the CBRA setting of the first release and the CBRA setting of the second release are the same, it is necessary to set a post - fix for the fields carrying the CBRA settings of different releases so as to indicate the release corresponding to the CBRA setting carried in the field.

[0033] Specifically, in one embodiment of the present disclosure, when the CBRA setting is a 4-step CBRA setting, the fields carrying the CBRA setting of the first release and the CBRA setting of the second release can be distinguished by different postfixes. Exemplarily, in one embodiment of the present disclosure, the field carrying the CBRA setting of the second release may be RACH-ConfigCommon-r17.

[0034] Also, in one embodiment of the present disclosure, when the CBRA setting is a 2-step CBRA setting, the field carrying the CBRA setting of the second release can be distinguished from the CBRA setting of the first release by different postfixes. Exemplarily, in one embodiment of the present disclosure, the field carrying the CBRA setting of the second release may be RACH-ConfigCommonTwoStepRA-r17.

[0035] In another embodiment of the present disclosure, the field carrying the CBRA setting of the second release can be distinguished from the CBRA setting of the first release by a different name. Exemplarily, in one embodiment of the present disclosure, when the CBRA setting is a 4-step CBRA setting, the CBRA setting of the second release may be carried in one new field. Exemplarily, the new field may be, for example, RACH-ConfigCommonExt-r17. In one embodiment of the present disclosure, when the CBRA setting is a 2-step CBRA setting, the CBRA setting of the second release may be carried in one new field. Exemplarily, the new field may be, for example, RACH-ConfigCommonTwoStepRAExt-r17.

[0036] In step 102, in response to the CFRA being triggered by the UE, it is determined whether an RSRP threshold is set in the CFRA setting.

[0037] Here, in one embodiment of the present disclosure, the UE triggering the CFRA can include at least one of triggering the CFRA based on BFR (Beam Failure Recovery), triggering the CFRA based on an SI (System Information) request, and triggering the CFRA based on a handover.

[0038] In step 103, if no RSRP threshold is set for the CFRA configuration, determine a target release including the first release and / or the second release, and determine a target RSRP threshold based on the RSRP threshold in the CBRA configuration of the target release.

[0039] In one embodiment of the present disclosure, the method for determining the target release can include at least one of determining the target release based on an instruction from a network-side device, determining the target release based on a protocol convention, determining the target release based on UE capabilities, and the UE autonomously determining the target release.

[0040] In one embodiment of the present disclosure, the method for determining the target release can specifically include at least one of determining the first release as the target release, determining the second release as the target release, and determining both the first release and the second release as the target release.

[0041] Specifically, in one embodiment of the present disclosure, the above method of "determining the target release" can be arbitrarily combined with the content included in the "target release" finally determined.

[0042] Exemplarily, in one embodiment of the present disclosure, when determining the target release based on the protocol convention, the first release may be determined as the target release based on the protocol convention, or the second release may be determined as the target release based on the protocol convention, or both the first release and the second release may be determined as the target releases based on the protocol convention.

[0043] In another embodiment of the present disclosure, when the UE autonomously determines the target release, the UE may autonomously determine the second release as the target release, or the UE may autonomously determine the first release as the target release, or the UE may autonomously determine both the first release and the second release as the target releases.

[0044] In another embodiment of the present disclosure, when determining the target release based on the instruction of the network-side device, the second release may be determined as the target release based on the instruction of the network-side device, or the first release may be determined as the target release based on the instruction of the network-side device, or both the first release and the second release may be determined as the target releases based on the instruction of the network-side device.

[0045] In another embodiment of the present disclosure, when determining the target release based on the UE capability, the second release may be determined as the target release based on the UE capability, or the first release may be determined as the target release based on the UE capability, or both the first release and the second release may be determined as the target releases based on the UE capability.

[0046] Also, in another embodiment of the present disclosure, when there is no instruction from the network-side device or the CBRA setting of the second release cannot be recognized and read based on the UE capability, the first release may be determined as the target release.

[0047] In addition, in one embodiment of the present disclosure, there is no mutually exclusive relationship among "acquiring the target release instructed by the network-side device", "determining the target release based on the protocol convention", "determining the target release based on the UE capability", and "the UE autonomously determining the target release", and they can cooperate with each other.

[0048] Exemplarily, in one embodiment of the present disclosure, the protocol may stipulate that the UE autonomously determines the second release as the target release.

[0049] Furthermore, in one embodiment of the present disclosure, after the UE determines the target release, the target RSRP threshold is determined based on the RSRP threshold in the CBRA setting of the target release. Here, in one embodiment of the present disclosure, when the types of the determined target RSRP thresholds are different, the selected CBRA settings are also different. Specifically, when the determined target RSRP threshold is the SUL selection threshold, the SUL selection threshold can be determined based on the 4-step CBRA setting of the target release; when the determined target RSRP threshold is the SSB selection threshold of the 2-step CFRA, the SSB selection threshold can be determined based on the 2-step CBRA setting of the target release; when the determined target RSRP threshold is the SSB selection threshold of the 4-step CFRA, the SSB selection threshold can be determined based on the 4-step CBRA setting of the target release.

[0050] Furthermore, in one embodiment of the present disclosure, the target release may correspond to one or more CBRA settings. Also, the method for determining the target RSRP threshold when the target release corresponds to one CBRA setting is different from the method for determining the target RSRP threshold when the target release corresponds to multiple CBRA settings. The content of this part will be described in detail in the subsequent embodiments.

[0051] As described above, in the method for determining a threshold in the CFRA provided by the embodiments of the present disclosure, the UE obtains the CBRA setting transmitted from the network-side device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, the first release precedes the second release, and in response to the CFRA being triggered by the UE, it is determined whether an RSRP threshold is set in the CFRA setting. Here, in response to the RSRP threshold being set in the CFRA setting, a target RSRP threshold is determined based on the RSRP threshold in the CFRA setting, and when the RSRP threshold is not set in the CFRA setting, a target release including the first release and / or the second release is determined, and a target RSRP threshold is determined based on the RSRP threshold in the CBRA setting of the target release. Thereby, in the embodiments of the present disclosure, a threshold determination method for determining a target RSRP threshold for CFRA from the CBRA setting is provided.

[0052] FIG. 2a is a schematic flowchart of a method for determining a threshold in the CFRA provided by the embodiments of the present disclosure. The method is executed by the UE. As shown in FIG. 2a, the method for determining a threshold in the CFRA may include the following steps.

[0053] In step 201a, obtain the CBRA setting transmitted from the network-side device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, and the first release precedes the second release.

[0054] In step 202a, in response to the CFRA being triggered by the UE, determine whether a reference signal received power (RSRP) threshold is set in the CFRA setting.

[0055] For other descriptions of steps 201a - 202a, reference may be made to the description of the above embodiments, and the description is omitted here in the embodiments of the present disclosure.

[0056] In step 203a, if no RSRP threshold is set in the CFRA setting, determine a target release including the first release and / or the second release, and in response to the target release corresponding to one CBRA setting, directly determine the RSRP threshold in the CBRA setting of the target release as the target RSRP threshold.

[0057] As described above, in the method for determining a threshold in CFRA provided by the embodiments of the present disclosure, a UE acquires a CBRA setting transmitted from a network-side device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, the first release precedes the second release, and in response to the CFRA being triggered by the UE, determine whether an RSRP threshold is set in the CFRA setting. Here, in response to an RSRP threshold being set in the CFRA setting, determine a target RSRP threshold based on the RSRP threshold in the CFRA setting, and if no RSRP threshold is set in the CFRA setting, determine a target release including the first release and / or the second release, and determine a target RSRP threshold based on the RSRP threshold in the CBRA setting of the target release. Thereby, in the embodiments of the present disclosure, a threshold determination method for determining a target RSRP threshold for CFRA from the CBRA setting is provided.

[0058] FIG. 2b is a schematic flowchart of a method for determining a threshold in CFRA provided by an embodiment of the present disclosure. The method is executed by a UE. As shown in FIG. 2b, the method for determining a threshold in the CFRA may include the following steps.

[0059] In step 201b, acquire a CBRA setting transmitted from a network-side device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, and the first release precedes the second release.

[0060] In step 202b, in response to the CFRA being triggered by the UE, it is determined whether an RSRP threshold is set according to the CFRA setting.

[0061] In step 203b, if no RSRP threshold is set according to the CFRA setting, a target release including the first release and / or the second release is determined, and in response to the target release corresponding to at least one CBRA setting, a target RSRP threshold is determined from the RSRP thresholds of at least one CBRA setting of the target release.

[0062] Here, in one embodiment of the present disclosure, the method for determining the target RSRP threshold from the RSRP thresholds of at least one CBRA setting of the target release may include at least one of the following methods 1 to 5.

[0063] In method 1, based on the instruction of the network-side device, the target RSRP threshold is determined from the RSRP thresholds of at least one CBRA setting of the target release.

[0064] In method 2, based on the UE capability, the target RSRP threshold is determined from the RSRP thresholds of at least one CBRA setting of the target release.

[0065] In one embodiment of the present disclosure, method 2 is premised on the second release being included in the target release. Also, the reading of the CBRA setting of the second release is restricted by the UE capability. Therefore, in one embodiment of the present disclosure, the method for the UE to determine the target RSRP threshold from the RSRP thresholds of at least one CBRA setting of the target release based on the UE capability may include determining to read at least one CBRA setting of the second release based on the UE capability, and determining the target RSRP threshold from the RSRP thresholds of the read CBRA settings.

[0066] In addition, in the CBRA configuration of the second release, each CBRA configuration corresponds to a combination of characteristics in the second release. For a UE that does not support a certain combination of characteristics, it cannot recognize and read the CBRA configuration corresponding to the combination of characteristics, and furthermore, the RSRP threshold value therein cannot be used.

[0067] Exemplarily, in one embodiment of the present disclosure, assume that the target release includes the second release, and the second release includes CBRA configuration 1, CBRA configuration 2, and CBRA configuration 3. Here, the combinations of characteristics corresponding to the CBRA configuration 1, CBRA configuration 2, and CBRA configuration 3 are Redcap, Slice, and CE respectively. Also, the combination of characteristics supported by the UE is Slice. In this case, the target RSRP threshold value can be determined from the RSRP threshold value of the CBRA configuration 2.

[0068] In Method 3, the RSRP threshold value in the CBRA configuration of the first release is determined as the target RSRP threshold value.

[0069] Here, in one embodiment of the present disclosure, Method 3 is premised on the fact that the target release includes the first release and one CBRA configuration corresponds to the first release.

[0070] Also, in one embodiment of the present disclosure, when the UE has not received an instruction from the network-side device or the UE capability does not support the CBRA configuration of the second release, by default, Method 3 is used, that is, the RSRP threshold value in the CBRA configuration of the first release is determined as the target RSRP threshold value.

[0071] In Method 4, based on a predefined rule, the target RSRP threshold value is determined from the RSRP threshold values of at least one CBRA configuration of the target release.

[0072] Here, in one embodiment of the present disclosure, the predefined rule may include at least one of determining the maximum RSRP threshold as the target RSRP threshold and determining the minimum RSRP threshold as the target RSRP threshold.

[0073] In Method Five, the UE autonomously determines the target RSRP threshold from the RSRP thresholds of at least one CBRA setting for target release.

[0074] Note that, in one embodiment of the present disclosure, any one of Methods One to Five may function independently, or they may function in cooperation to ensure that a unique target RSRP threshold is finally determined.

[0075] Exemplarily, in one embodiment of the present disclosure, when the UE has one capability and supports a combination of characteristics corresponding to the one UE capability and can read the CBRA setting corresponding to the combination of characteristics, a unique target RSRP threshold can be determined based only on Method Two, that is, based on the UE capability, a unique target RSRP threshold can be determined from the RSRP thresholds of at least one CBRA setting for target release.

[0076] In another embodiment of the present disclosure, when the UE capability supports reading multiple CBRA settings, multiple RSRP thresholds can be determined based on Method Two above. Based on this, a unique target RSRP threshold can be further determined from the multiple RSRP thresholds determined based on the UE capability according to Method One, Method Four, Method Five, or protocol specifications.

[0077] As described above, in the method for determining a threshold in the CFRA provided by the embodiments of the present disclosure, the UE obtains the CBRA setting transmitted from the network device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, the first release precedes the second release, and in response to the CFRA being triggered by the UE, it is determined whether an RSRP threshold is set in the CFRA setting. Here, in response to the RSRP threshold being set in the CFRA setting, a target RSRP threshold is determined based on the RSRP threshold in the CFRA setting, and when no RSRP threshold is set in the CFRA setting, a target release including the first release and / or the second release is determined, and a target RSRP threshold is determined based on the RSRP threshold in the CBRA setting of the target release. Thereby, in the embodiments of the present disclosure, a threshold determination method for determining a target RSRP threshold for CFRA from the CBRA setting is provided.

[0078] FIG. 2c is a schematic flowchart of a method for determining a threshold in the CFRA provided by the embodiments of the present disclosure. The method is executed by the UE. As shown in FIG. 2c, the method for determining a threshold in the CFRA may include the following steps.

[0079] In step 201c, obtain the CBRA setting transmitted from the network device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, and the first release precedes the second release.

[0080] In step 202c, in response to the CFRA being triggered by the UE, determine whether a reference signal received power (RSRP) threshold is set in the CFRA setting.

[0081] In step 203c, when an RSRP threshold is set in the CFRA setting, determine a target RSRP threshold based on the RSRP threshold in the CFRA setting.

[0082] Here, in one embodiment of the present disclosure, the method for determining the target RSRP threshold based on the RSRP threshold in the CFRA setting may include directly determining the RSRP threshold in the CFRA setting as the target RSRP threshold.

[0083] Here, for a detailed description of steps 201c - 203c, reference may be made to the description of the above embodiments, and the description of the embodiments of the present disclosure is omitted here.

[0084] As described above, in the method for determining the threshold in the CFRA provided by the embodiments of the present disclosure, the UE obtains the CBRA setting transmitted from the network - side device, the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, the first release precedes the second release, and in response to the CFRA being triggered by the UE, it is determined whether an RSRP threshold is set in the CFRA setting. Here, in response to the RSRP threshold being set in the CFRA setting, a target RSRP threshold is determined based on the RSRP threshold in the CFRA setting, and when the RSRP threshold is not set in the CFRA setting, a target release including the first release and / or the second release is determined, and a target RSRP threshold is determined based on the RSRP threshold in the CBRA setting of the target release. Thereby, in the embodiments of the present disclosure, a threshold - determination method for determining the target RSRP threshold for CFRA from the CBRA setting is provided.

[0085] FIG. 3 is a schematic flowchart of the method for determining the threshold in the CFRA provided by the embodiments of the present disclosure. The method is executed by the UE. As shown in FIG. 3, the method for determining the threshold in the CFRA may include the following steps.

[0086] In step 301, obtain the CFRA setting transmitted from the network - side device.

[0115] In step 601, a CFRA setting is transmitted to the UE.

[0116] In step 602, a CBRA setting is transmitted to the UE, and the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release. Here, the first release precedes the second release.

[0117] In step 603, in response to the CFRA being triggered by the UE and the RSRP threshold not being set in the CFRA setting, the UE is instructed of a target release including the first release and / or the second release.

[0118] Here, for the detailed description of steps 601-603, reference can be made to the description of the above embodiments, and the embodiments of the present disclosure will be omitted here.

[0119] As described above, in the method for determining the threshold in CFRA provided by the embodiments of the present disclosure, the UE obtains the CBRA setting transmitted from the network-side device, and the CBRA setting includes at least one of the CBRA setting of the first release and the CBRA setting of the second release, the first release precedes the second release, and in response to the CFRA being triggered by the UE, it is determined whether an RSRP threshold is set in the CFRA setting. Here, in response to the RSRP threshold being set in the CFRA setting, a target RSRP threshold is determined based on the RSRP threshold in the CFRA setting, and when no RSRP threshold is set in the CFRA setting, a target release including the first release and / or the second release is determined, and a target RSRP threshold is determined based on the RSRP threshold in the CBRA setting of the target release. Thereby, in the embodiments of the present disclosure, a threshold determination method for determining a target RSRP threshold for CFRA from the CBRA setting is provided.

[0120] In combination with the above content, examples are given to illustrate the method for determining different types of target RSRP thresholds.

[0121] In Example 1, the UE that triggers CFRA needs to determine the SUL selection threshold (rsrp-ThresholdSSB-SUL). The determination method can include that when the serving cell sets SUL, the terminal that triggers CFRA determines the SUL selection threshold (rsrp-ThresholdSSB-SUL) based on the network setting, and further includes the step of determining whether to select the SUL carrier.

[0122] Here, the CFRA includes any one of the CFRA triggered based on BFR, the CFRA triggered based on SI request, and the CFRA triggered based on handover.

[0123] Here, the network configuration includes at least one of a 4-step CBRA configuration (RACH-ConfigCommon) of the first release and one or more 4-step CBRA configurations of the second release. Here, the possible IE designs for the 4-step CBRA configuration of the second release are: postfix change, i.e., RACH-ConfigCommon-r17, and the possible IE design for the 4-step CBRA configuration of the second release is: IE name change, i.e., RACH-ConfigCommonExt-R17.

[0124] Here, determining the SUL selection threshold can be done by any one of the following methods: Method 1 where the terminal uses the SUL selection threshold indicated in the 4-step CBRA configuration (RACH-ConfigCommon) of the first release; Method 2 where the terminal uses the SUL selection threshold indicated in the 4-step CBRA configuration of the second release; and Method 3 where the terminal uses the SUL selection threshold indicated in the 4-step CBRA configuration of the first release and the 4-step CBRA configuration of the second release transmitted from the base station.

[0125] Furthermore, for any of the above methods, when there are multiple SUL selection thresholds, the terminal determines which SUL selection threshold indicated in which CBRA configuration to use based on network indication and / or terminal capabilities. If not indicated by the network or not supported by terminal capabilities, it can be further determined by any one of the following methods: Method a where the terminal uses the SUL selection threshold indicated in the 4-step CBRA configuration (RACH-ConfigCommon) of the first release; Method b where it is determined based on a predefined selection rule, for example, using the maximum or minimum SUL selection threshold; and Method c implemented by the terminal.

[0126] In Example 2, the UE that triggers the two-step CFRA needs to determine the SSB selection threshold (msgA-RSRP-ThresholdSSB). The determination method includes the steps that when the network configures the two-step CFRA resource related to the SSB, the terminal selects the SSB based on the SSB selection threshold (msgA-RSRP-ThresholdSSB) configured by the network, and further determines the CFRA resource.

[0127] Here, the network configuration includes at least one of the two-step CBRA configuration of the first release (RACH-ConfigCommonTwoStepRA-r16) and the two-step CBRA configuration of one or more second releases. The possible IE design of the two-step CBRA configuration of the second release: postfix change, that is, RACH-ConfigCommonTwoStepRA-r17, and the possible IE design of the two-step CBRA configuration of the second release: IE name change, that is, RACH-ConfigCommonTwoStepRAExt-R17.

[0128] Here, the determination of the SSB selection threshold can be made by any one of Method 1 in which the terminal uses the SSB selection threshold indicated in the two-step CBRA configuration of the first release (RACH-ConfigCommonTwoStepRA-r16), Method 2 in which the terminal uses the SSB selection threshold indicated in the two-step CBRA configuration of the second release, and Method 3 in which the terminal uses the SSB selection threshold indicated in the two-step CBRA configuration of the first release and the two-step CBRA configuration of the second release transmitted from the base station.

[0129] Furthermore, for any of the above methods, when there are multiple SSB selection thresholds, the terminal determines which SSB selection threshold indicated in which CBRA setting to use based on network instructions and / or terminal capabilities. When not indicated by the network or not supported by terminal capabilities, it can be further determined by any of the following: Method a, which uses the SSB selection threshold indicated in the 2-step CBRA setting (RACH-ConfigCommon) of Release 1; Method b, which is determined based on a predefined selection rule, for example, using the maximum or minimum SSB selection threshold; and Method c, which is implemented by the terminal.

[0130] In Example 3, when a UE that triggers 4-step CFRA needs to determine the SSB selection threshold (RSRP-ThresholdSSB), the determination method includes the step that when the network configures 4-step CFRA resources related to SSB, the terminal selects the SSB based on the SSB selection threshold (RSRP-ThresholdSSB) configured by the network and further determines the CFRA resources.

[0131] Here, the 4-step CFRA includes any one of the 4-step CFRA triggered based on SI request and the 4-step CFRA triggered based on handover.

[0132] Here, the network configuration includes at least one of the 4-step CBRA setting (RACH-ConfigCommon) of Release 1 and one or more 4-step CBRA settings of Release 2. Possible IE designs for the 4-step CBRA setting of Release 2: Postfix change, that is, RACH-ConfigCommon-r17; Possible IE design for the 4-step CBRA setting of Release 2: IE name change, that is, RACH-ConfigCommonExt-R17.

[0133] Here, determining the SSB selection threshold can be done by any one of the following methods: Method 1 where the terminal uses the SSB selection threshold indicated in the 4-step CBRA configuration (RACH-ConfigCommon) of Release 1; Method 2 where the terminal uses the SSB selection threshold indicated in the 4-step CBRA configuration of Release 2; Method 3 where the terminal uses the SSB selection threshold indicated in the 4-step CBRA configuration of Release 1 and the 4-step CBRA configuration of Release 2 transmitted from the base station.

[0134] Furthermore, for any of the above methods, when there are multiple SSB selection thresholds, the terminal determines which SSB selection threshold indicated in which CBRA configuration to use based on network indication and / or terminal capabilities. If not indicated by the network or not supported by terminal capabilities, it can be further determined by any one of the following: Method a where the terminal uses the SSB selection threshold indicated in the 4-step CBRA configuration (RACH-ConfigCommon) of Release 1; Method b where it is determined based on a predefined selection rule, for example, using the maximum or minimum SSB selection threshold; Method c where it is realized by the terminal.
