The method for determining the random access timing resource information includes: triggering a two-step non-contention-based random access (CFRA); when there is no independently configured random access timing (RO) resource information for the terminal in the CFRA configuration information, determining the RO resource information of the triggered two-step CFRA based on the RO resource information of a specified version of contention-based random access (CBRA). According to this disclosure, the terminal can determine the RO resource information of the triggered two-step CFRA based on the RO resource information of a specified version of CBRA.

Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a method for determining random access timing resource information, a method for indicating random access timing resource information, a method for configuring non-contention-based random access, an apparatus for determining random access timing resource information, an apparatus for indicating random access timing resource information, an apparatus for configuring non-contention-based random access, a communication apparatus, and a computer-readable storage medium. Background Technology

[0002] In some scenarios, a terminal can trigger random access. Random access can be classified by steps, including 2-step random access and 4-step random access. Random access can also be classified by contention type, including contention-based random access (CBRA) and contention-free random access (CFRA).

[0003] In the case of 2-step CFRA, after triggering 2-step CFRA, the terminal needs to initiate 2-step CFRA at the random access occasion, also known as the physical random access channel occasion (PRACH occasion, RO). Therefore, the terminal first needs to determine the RO resource information of 2-step CFRA.

[0004] However, in some cases, the network side does not indicate RO resources in the CFRA configuration information. In such cases, the terminal can use the RO resources in the 2-step CBRA configuration information or the 4-step CBRA configuration information.

[0005] With the development of random communication technology, the application scenarios have also expanded. In order to adapt to the feature characteristics of different scenarios, different CBRA configuration information can be configured for different features. Therefore, a terminal can be configured with multiple CBRA configuration information. This will make it difficult for the terminal to determine which RO resource in the CBRA configuration information to use for CFRA when it does not find the RO resource information in the CFRA configuration information.

[0043] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0044] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0045] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0046] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0047] After triggering the 2-step CFRA, the terminal needs to initiate the CFRA at the random access opportunity (RO, also known as the physical random access channel opportunity). Therefore, the terminal first needs to determine the RO resource information for the 2-step CFRA.

[0048] Generally, the RO resource information for a two-step CFRA is indicated in the CFRA configuration through the information element occasionsTwoStepRA. The occasionsTwoStepRA information element further contains two parts: one part is the RO configuration information, indicated by rach-ConfigGenericTwoStepRA, and the other part is the correspondence between the Synchronization Signal Block (SSB) and the RO, indicated by ssb-PerRACH-OccasionTwoStepRA. The terminal can determine the RO that initiates the two-step CFRA based on these two parts.

[0049] However, in some cases, the network side does not indicate complete RO resource information in the CFRA configuration information.

[0050] For example, if the entire RO resource information is not indicated, that is, if the information element occasionsTwoStepRA is defaulted in the CFRA configuration information, the terminal can use the RO resources in the 2-step CBRA configuration information.

[0051] For example, if the RO configuration information in the RO resource information is not indicated, that is, if the information element occurrences TwoStepRA in the CFRA configuration information is defaulted, the terminal can use the RO configuration information in the RO resource information in the 4-step CBRA configuration information.

[0052] However, with the development of random communication technology, the application scenarios have also expanded. For example, in R17, in order to adapt to the feature characteristics of different scenarios, such as Slicing, Small Data Transmission (SDT), Coverage Enhancement (CE), and Reduced Capability (Redcap), different CBRA configuration information can be configured for different features. That is, the terminal will be configured with the RO resource information of the R17 version CBRA. Among them, the RO resource information of the R17 version 2-step CBRA can include the RO resource information of multiple CBRAs, such as multiple 2-step CBRA RO resource information and multiple 4-step CBRA RO resource information.

[0053] Furthermore, the terminal will also be configured with RO resource information for the traditional legacy version of CBRA, such as the RO resource information for R15 and R16 versions of CBRA. In the legacy version, the network-side device will not configure different CBRA configuration information for the terminal based on the above characteristics, but will only configure RO resource information for a 2-step CBRA and RO resource information for a 4-step CBRA for the terminal.

[0054] Therefore, for a terminal, when both legacy and R17 versions of CBRA RO resource information are configured, there are multiple versions of CBRA RO resource information. Faced with these multiple versions, the terminal may struggle to determine which version of CBRA RO resource information to use to determine the 2-step CFRA RO resource information. The following embodiments of this disclosure are primarily proposed to address this technical problem.

[0055] Figure 1 This is a schematic flowchart illustrating a method for determining random access timing resource information according to an embodiment of this disclosure. The method for determining random access timing resource information shown in this embodiment can be applied to terminals, including but not limited to mobile phones, tablets, wearable devices, sensors, IoT devices, and other communication devices. The terminal can communicate with network-side devices, including but not limited to network-side devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0056] like Figure 1 As shown, the method for determining the random access timing resource information may include the following steps:

[0057] In step S101, a two-step non-contention random access CFRA is triggered;

[0058] In step S102, if there is no independently configured random access opportunity (RO) resource information for the terminal in the CFRA configuration information, the RO resource information of the triggered 2-step CFRA is determined according to the RO resource information of the specified version of the contention random access CBRA.

[0059] In one embodiment, the terminal may trigger a 2-step CFRA under certain circumstances, wherein the 4-step CFRA is triggered by a toggle Handover command.

[0060] After triggering a 2-step CFRA, the terminal needs to determine the RO resource information for the 2-step CFRA. For example, it needs to determine whether there is RO resource information configured independently for the terminal in the CFRA configuration information. If there is RO resource information configured independently for the terminal, the terminal can determine the RO for initiating the 2-step CFRA based on the RO resource information configured independently for the terminal. If there is no RO resource information configured independently for the terminal, the terminal can determine the RO resource information for the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA or the RO resource information of the 4-step CBRA.

[0061] According to embodiments of this disclosure, the terminal can determine the RO resource information for the triggered two-step CFRA based on the RO resource information of a specified version of CBRA. Therefore, even if the terminal is configured with RO resource information from both legacy and R17 versions of CBRA, it can accurately determine which version of CBRA's RO resource information to use to determine the triggered two-step CFRA's RO resource information. This avoids the technical problem of the terminal struggling to determine which version of CBRA's RO resource information to use when faced with multiple versions of CBRA's RO resource information.

[0062] In one embodiment, the specified version is determined according to instructions from the network-side device or according to a protocol agreement.

[0063] The terminal can determine the specified version according to the network-side device's indication. For example, if the specified version indicated by the network-side device is R17, then the terminal determines the RO resource information of the triggered 2-step CFRA based on the random access timing RO resource information of the CBRA in version R17. For example, if the specified version indicated by the network-side device is legacy, then the terminal determines the RO resource information of the triggered 2-step CFRA based on the random access timing RO resource information of the CBRA in version legacy.

[0064] The terminal can also determine the specified version according to the protocol. For example, if the specified version is R17, the terminal will determine the RO resource information of the triggered 2-step CFRA based on the random access timing RO resource information of the CBRA in the R17 version. If the specified version is legacy, the terminal will determine the RO resource information of the triggered 2-step CFRA based on the random access timing RO resource information of the CBRA in the legacy version.

[0065] In one embodiment, the designated version includes at least one of the following: a legacy version and R17 version. In one embodiment, the legacy version includes at least one of the following: R15 version and R16 version.

[0066] In one embodiment, the RO resource information includes at least one of the following:

[0067] RO configuration information;

[0068] The correspondence between the synchronization signal block SSB and RO.

[0069] In one embodiment, the RO resource information may include two parts: RO configuration information and the correspondence between SSB and RO. The terminal determines the RO resource information of the triggered 2-step CFRA based on the RO resource information of the specified version of the contention-based random access CBRA. This includes two corresponding cases: one is to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA, and the other is to determine the correspondence between SSB and RO in the RO resource information of the 2-step CFRA.

[0070] Correspondingly, the CFRA configuration information does not include the random access timing (RO) resource information configured independently for the terminal. This includes two cases: one is that only the RO configuration information is missing in the RO resource information; the other is that the entire RO resource information is missing.

[0071] If only the RO configuration information is missing in the RO resource information, it is necessary to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA. For example, the RO configuration information in the RO resource information of the triggered 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the 2-step CFRA.

[0072] With all RO resource information set to default, it is necessary to determine the RO configuration information and the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA. For example, the RO configuration information in the RO resource information of the triggered 2-step CFRA can be determined based on the RO configuration information in the 4-step CBRA. How to determine the correspondence between SSB and RO will be explained in subsequent embodiments.

[0073] The following examples illustrate how to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA.

[0074] Figure 2 This is a schematic flowchart illustrating another method for determining random access timing resource information according to embodiments of this disclosure. Figure 2 As shown, the RO resource information includes RO configuration information. When the CFRA configuration information does not include RO resource information for the terminal under independent random access timing, the RO resource information for the triggered 2-step CFRA is determined based on the RO resource information of the specified version of contention-based random access CBRA, including:

[0075] In step S201, if no independent RO configuration information is configured for the terminal in the CFRA configuration information, the RO configuration information in the RO resource information of the specified version of the 4-step CBRA is determined to be the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0076] In one embodiment, the RO resource information includes RO configuration information, that is, the CFRA configuration information does not include RO resource information independently configured for the terminal, or at least includes RO configuration information in the CFRA configuration information that is not independently configured for the terminal.

[0077] In this case, the terminal can determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0078] Figure 3 This is a schematic flowchart illustrating another method for determining random access timing resource information according to embodiments of this disclosure. Figure 3 As shown, determining the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0079] In step S301, the RO configuration information in the RO resource information of the legacy version of the 4-step CBRA is determined to be the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0080] In one embodiment, the specified version can be a legacy version. In this case, the terminal can determine the RO configuration information in the RO resource information of the 4-step CBRA of the legacy version as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0081] Figure 4 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 4 As shown, determining the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0082] In step 401, among the RO resource information of multiple 4-step CBRAs in R17 version, the RO configuration information in some or all of the resource information is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0083] In one embodiment, the specified version can be R17. Since different CBRA configuration information can be configured for different features in R17, the terminal can be configured with RO resource information for multiple 4-step CBRAs in R17.

[0084] In this scenario, the terminal can determine the RO configuration information in a portion (which can be one or more) of the RO resource information in multiple 4-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA; alternatively, it can determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0085] Specifically, in the R17 version, the terminal determines the RO configuration information in a portion of the RO resource information of multiple 4-step CBRAs as the RO configuration information in the triggered 2-step CFRA. The portion of the resource information can be determined based on a predefined list of 4-step CBRA configuration information in R17. For example, multiple RO configuration information can be arranged in order in the list. The portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0086] In addition, the terminal determines the RO configuration information in the total resource information as the RO configuration information in the triggered 2-step CFRA, which means that the RO configured in the total resource information is available to the terminal.

[0087] In one embodiment, determining the RO configuration information in some or all of the RO resource information in the multiple 4-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0088] When receiving an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in R17, the RO configuration information in some or all of the RO resource information of the multiple 4-step CBRA in R17 is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0089] The method further includes:

[0090] If no instruction is received from the network-side device to determine the RO configuration information in the triggered 2-step CFRA based on the RO configuration information in the 4-step CBRA of the legacy version, the RO configuration information in the triggered 2-step CFRA is determined based on the RO configuration information in the 4-step CBRA of the legacy version.

[0091] In one embodiment, the terminal can determine, based on instructions from the network-side device, whether to identify the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs of R17 as the RO configuration information in the triggered 2-step CFRA.

[0092] For example, when the terminal receives an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in R17, the terminal can determine the RO configuration information in some or all of the RO resource information of the multiple 4-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA.

[0093] If no instruction is received from the network-side device to determine the RO configuration information in the triggered 2-step CFRA based on the RO configuration information in the 4-step CBRA of the legacy version, then the RO configuration information in the triggered 2-step CFRA can be determined based on the RO configuration information in the 4-step CBRA of the legacy version.

[0094] In one embodiment, determining the RO configuration information in some or all of the RO resource information in the multiple 4-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0095] When the terminal supports determining the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the RO configuration information in the 4-step CBRA of R17 version, the RO configuration information in some or all of the RO resource information in the multiple 4-step CBRAs of R17 version will be determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0096] The method further includes:

[0097] The terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, and determining the RO configuration information of the triggered 2-step CFRA based on the RO configuration information of the 4-step CBRA in the legacy version.

[0098] In one embodiment, the terminal can determine, based on its own capabilities, whether to identify the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs of R17 version as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0099] For example, if a system is capable of determining the RO resource information of a triggered 2-step CFRA based on the RO resource information of a 4-step CBRA in R17, it can determine the RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA.

[0100] If the terminal's capabilities do not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, then the RO configuration information of the triggered 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the 4-step CBRA in the legacy version.

[0101] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The terminal can determine which features it supports among these features. Then, the terminal can determine the RO resource information corresponding to one or more 4-step CBRAs from the RO resource information of multiple 4-step CBRAs in Release 17, and further determine the RO configuration information in the RO resource information of the triggered 2-step CFRA from the determined RO resource information of the one or more 4-step CBRAs.

[0102] For example, if the network-side device configures the RO resource information for four 4-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and the terminal's capability only supports the CE and Redcap features, then the terminal can determine the RO resource information for the two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 4-step CBRAs in R17 version, and then determine the RO configuration information in the RO resource information of the triggered two 2-step CBRAs from the determined RO resource information of the two 4-step CBRAs.

[0103] In one embodiment, determining the RO configuration information in some or all of the RO resource information of the multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0104] According to the terminal implementation, in the RO resource information of multiple 4-step CBRAs in R17 version, some or all of the RO configuration information in the 4-step CBRAs of R17 version are determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0105] For example, if the terminal determines, based on its own implementation, that the RO resource information in the multiple 4-step CBRAs of R17 version is not present, and determines the RO configuration information in the RO resource information of the 4-step CBRA of R17 version as the RO configuration information in the RO resource information of the triggered 2-step CFRA, then the RO configuration information in the RO resource information of the triggered 2-step CFRA can be determined based on the RO configuration information in the 4-step CBRA of the legacy version.

[0106] For example, the terminal can determine the RO configuration information in the RO resource information of a portion of the 4-step CBRA in R17 version as the RO configuration information in the triggered 2-step CFRA, based on its own implementation in multiple 4-step CBRA RO resource information.

[0107] For example, the terminal can determine the RO configuration information in all the RO resource information of the four-step CBRA of the R17 version as the RO configuration information in the triggered two-step CFRA based on its own implementation in the RO resource information of multiple four-step CBRAs in R17 version.

[0108] It should be noted that the terminal implementation can be combined with the network-side device instructions and other embodiments described above. For example, the network-side device instructs the terminal to determine some or all of the RO configuration information in the RO resource information of the multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA. The terminal can, according to its own implementation, select one or more of the RO configuration information in the multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0109] Figure 5 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 5 As shown, determining the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0110] In step S501, the RO configuration information in some or all of the resource information in the legacy version of the 4-step CBRA and the multiple 4-step CBRAs in the R17 version is determined to be the RO configuration information in the triggered 2-step CFRA.

[0111] In one embodiment, the specified version may include the legacy version and the R17 version. Since different CBRA configuration information can be configured for different features in the R17 version, the terminal can be configured with RO resource information for multiple 4-step CBRAs in the R17 version.

[0112] In this scenario, the terminal can determine the RO configuration information in a portion (which can be one or more) of the RO resource information in the legacy version's 4-step CBRA and the RO resource information in multiple 4-step CBRAs in the R17 version as the RO configuration information in the triggered 2-step CFRA; alternatively, it can determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0113] Specifically, when the terminal determines the RO configuration information in a portion of the RO resource information in at least multiple 4-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA, the portion of the resource information can be determined based on a predefined list of 4-step CBRA configuration information of R17. For example, multiple RO configuration information can be arranged in order in the list, and the portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0114] In addition, the terminal determines the RO configuration information in the total resource information as the RO configuration information in the triggered 2-step CFRA, which means that the RO configured in the total resource information is available to the terminal.

[0115] In one embodiment, determining the RO configuration information in some or all of the resource information from the legacy version's 4-step CBRA and the RO resource information of multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0116] When receiving an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in the legacy version and the RO resource information of the 4-step CBRA in the R17 version, the RO configuration information in some or all of the resource information in the 4-step CBRA in the legacy version and the RO resource information of multiple 4-step CBRA in the R17 version is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0117] The method further includes:

[0118] If no instruction is received from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version 4-step CBRA and the R17 version 4-step CBRA, the RO configuration information in the RO resource information of the triggered 2-step CFRA is determined based on the RO resource information of the legacy version 4-step CBRA.

[0119] In one embodiment, the terminal can determine, based on instructions from the network-side device, whether to determine the RO configuration information in some or all of the RO resource information in the legacy version's 4-step CBRA and the RO resource information of multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0120] For example, when receiving an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version's 4-step CBRA and the R17 version's 4-step CBRA, the RO configuration information in some or all of the resource information in the legacy version's 4-step CBRA and the multiple 4-step CBRA RO resource information in the R17 version can be determined as the RO configuration information in the triggered 2-step CFRA's RO resource information.

[0121] If no instruction is received from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version's 4-step CBRA and the R17 version's 4-step CBRA, then the RO configuration information in the triggered 2-step CFRA's RO resource information can be determined based on the RO configuration information in the legacy version's 4-step CBRA's RO resource information.

[0122] In one embodiment, determining the RO configuration information in some or all of the resource information from the legacy version's 4-step CBRA and the RO resource information of multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0123] When the terminal supports determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, the RO configuration information in some or all of the resource information in the legacy version of the 4-step CBRA and the multiple 4-step CBRA RO resource information in version R17 will be determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0124] The method further includes:

[0125] When the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, the RO configuration information of the triggered 2-step CFRA is determined based on the RO configuration information in the RO resource information of the 4-step CBRA in the legacy version.

[0126] In one embodiment, the terminal can determine, based on its own capabilities, whether to identify the RO configuration information in some or all of the RO resource information in the legacy version's 4-step CBRA and the RO resource information of multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0127] For example, if a system is capable of determining the RO resource information of a triggered 2-step CFRA based on the RO resource information of a 4-step CBRA in version R17, it can determine the RO configuration information in some or all of the resource information from the RO resource information of the legacy version of the 4-step CBRA and the RO resource information of multiple 4-step CBRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0128] If the system's own capabilities do not support determining the RO resource information of the triggered 4-step CFRA based on the RO resource information of the 4-step CBRA in version R17, it can determine the RO configuration information of the triggered 2-step CFRA based solely on the RO configuration information in the RO resource information of the 4-step CBRA in the legacy version.

[0129] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The terminal can determine which features it supports. When the terminal determines the RO resource information for a triggered 2-step CFRA based at least on the RO resource information of the 4-step CFRA in R17, the terminal can determine one or more 4-step CBRA RO resource information corresponding to the supported features from multiple 4-step CBRA RO resource information sets in R17, and then determine the RO configuration information in the triggered 2-step CFRA RO resource information from the determined one or more 4-step CBRA RO resource information.

[0130] For example, if the network-side device configures the RO resource information for four 4-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and the terminal's capability only supports the CE and Redcap features, then the terminal can determine the RO resource information for the two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 4-step CBRAs in R17 version, and then determine the RO configuration information in the RO resource information of the triggered two 2-step CBRAs from the determined RO resource information of the two 4-step CBRAs.

[0131] In one embodiment, determining the RO configuration information in some or all of the RO resource information of the multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0132] Based on the terminal implementation, in the RO resource information of the 4-step CBRA in the legacy version and the RO resource information of multiple 4-step CBRAs in the R17 version, the RO configuration information in some or all of the resource information is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0133] For example, the terminal itself can determine the RO configuration information in some or all of the resource information in the legacy version's 4-step CBRA and the RO resource information of multiple 4-step CBRA in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0134] For example, the terminal itself can implement this by only needing to determine the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0135] For example, the terminal itself can determine the RO configuration information in the triggered 2-step CFRA RO resource information based solely on the RO resource information of the legacy version's 4-step CBRA.

[0136] The following examples illustrate how to determine the RO resource information for a triggered 2-step CFRA when all RO resource information is defaulted.

[0137] Figure 6 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 6As shown, the RO resource information includes RO configuration information and the corresponding relationship. When the CFRA configuration information does not have RO resource information configured for the terminal for an independent random access opportunity, the RO resource information for the triggered 2-step CFRA is determined based on the RO resource information of the specified version of the contention-based random access CBRA, including:

[0138] In step S601, if the terminal is not configured with an independent RO configuration and the corresponding relationship in the CFRA configuration information, the RO configuration information in the RO resource information of the specified version of the two-step contention random access CBRA is determined to be the RO configuration information in the triggered two-step CFRA RO resource information.

[0139] In one embodiment, if the RO resource information includes RO configuration information and the corresponding relationship, that is, if the CFRA configuration information does not contain an RO configuration and the corresponding relationship configured independently for the terminal, then the terminal can determine the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0140] Figure 7 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 7 As shown, determining the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0141] In step S701, the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA is determined to be the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0142] In one embodiment, the specified version can be a legacy version. In this case, the terminal can determine the RO configuration information in the RO resource information of the 2-step CFRA of the legacy version as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0143] Figure 8 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 8 As shown, determining the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0144] In step S801, among the RO resource information of multiple 2-step CBRAs in R17 version, the RO configuration information in some or all of the resource information is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0145] In one embodiment, the specified version can be R17. Since different CBRA configuration information can be configured for different features in R17, the terminal can be configured with RO resource information for multiple 2-step CBRAs in R17.

[0146] In this scenario, the terminal can determine the RO configuration information in a portion (which can be one or more) of the RO resource information in multiple 2-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA RO resource information; alternatively, it can determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0147] Specifically, in the R17 version, the terminal determines the RO configuration information in a portion of the RO resource information of multiple 2-step CBRAs as the RO configuration information in the triggered 2-step CBRA. The portion of the resource information can be determined based on a predefined list of 2-step CBRA configuration information in R17. For example, multiple RO configuration information can be arranged in order in the list. The portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0148] In addition, the terminal determines the RO configuration information in the total resource information as the RO configuration information in the triggered 2-step CFRA, which means that the RO configured in the RO configuration information in the total resource information is available to the terminal.

[0149] In one embodiment, determining the RO configuration information in some or all of the RO resource information in the multiple 2-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0150] When receiving an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CFRA in R17, the RO configuration information in some or all of the RO resource information of the multiple 2-step CFRAs in R17 is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0151] The method further includes:

[0152] If no instruction is received from the network-side device to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the legacy version 2-step CFRA, the RO configuration information in the RO resource information of the triggered 2-step CFRA will be determined based on the RO configuration information in the legacy version 2-step CFRA.

[0153] In one embodiment, the terminal may determine, based on instructions from the network-side device, whether to identify the RO configuration information in some or all of the RO resource information in multiple 2-step CBRAs of R17 as the RO configuration information in the triggered 2-step CFRA.

[0154] For example, when the terminal receives an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in R17, the terminal can determine the RO configuration information in some or all of the RO resource information in the multiple 2-step CBRA RO resource information in R17 as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0155] If no instruction is received from the network-side device to determine the RO configuration information in the triggered 2-step CFRA RO resource information based on the RO configuration information in the 2-step CBRA RO resource information of the R17 version, then the RO configuration information in the triggered 2-step CFRA RO resource information can be determined based on the RO configuration information in the 2-step CBRA RO resource information of the legacy version.

[0156] In one embodiment, determining the RO configuration information in some or all of the RO resource information in the multiple 2-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0157] When the terminal supports determining the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the 2-step CFRA of R17 version, the RO configuration information in some or all of the RO resource information of multiple 2-step CFRAs in R17 version will be determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0158] The method further includes:

[0159] The terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CFRA in version R17, but rather determines the RO configuration information of the triggered 2-step CFRA based on the RO configuration information of the 2-step CFRA in the legacy version.

[0160] In one embodiment, the terminal may determine, based on its own capabilities, whether to identify the RO configuration information in some or all of the RO resource information in multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0161] For example, if a system is capable of determining the RO resource information of a triggered 2-step CFRA based on the RO resource information of a 2-step CBRA in version R17, it can determine the RO configuration information in some or all of the RO resource information of multiple 2-step CBRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0162] If the terminal's capabilities do not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in version R17, then the RO configuration information of the triggered 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA.

[0163] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The terminal can determine which features it supports among these features. Then, the terminal can determine the RO resource information for one or more 2-step CBRAs corresponding to the supported features from the RO resource information of multiple 2-step CBRAs in Release 17, and further determine the RO configuration information in the RO resource information of the triggered 2-step CBRA from the determined RO resource information of one or more 2-step CBRAs.

[0164] For example, if the network-side device configures the RO resource information for four 2-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and the terminal's capability only supports the CE and Redcap features, then the terminal can determine the RO resource information for the two 2-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 2-step CBRAs in R17 version, and then determine the RO configuration information in the RO resource information of the triggered 2-step CBRA from the determined RO resource information of the two 2-step CBRAs.

[0165] In one embodiment, determining the RO configuration information in some or all of the RO resource information of the multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0166] According to the terminal implementation, in the RO resource information of multiple 2-step CBRAs in R17 version, some or all of the RO configuration information in the 2-step CBRAs of R17 version are determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0167] For example, if the terminal determines, based on its own implementation, that the RO resource information of the multiple 2-step CBRAs in R17 version is not present, and determines the RO configuration information in the RO resource information of the 2-step CBRAs in R17 version as the RO configuration information in the RO resource information of the triggered 2-step CFRA, then the RO configuration information in the RO resource information of the triggered 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA.

[0168] For example, the terminal can determine the RO configuration information in the RO resource information of a portion of the 2-step CBRA in R17 version as the RO configuration information in the triggered 4-step CFRA, based on its own implementation.

[0169] For example, the terminal can determine the RO configuration information in all the RO resource information of the 4-step CBRA of the R17 version as the RO configuration information in the triggered 4-step CFRA based on its own implementation in the RO resource information of multiple 4-step CBRAs in R17 version.

[0170] It should be noted that the terminal implementation can be combined with the network-side device instructions and other embodiments described above. For example, the network-side device instructs the terminal to determine some or all of the RO configuration information in the RO resource information of the multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 4-step CFRA. The terminal can, according to its own implementation, select one or determine the RO configuration information in the RO resource information of the multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 4-step CFRA.

[0171] Figure 9 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 9As shown, determining the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0172] In step S901, the RO configuration information in some or all of the resource information of the legacy version of the 2-step CBRA and the RO resource information of multiple 2-step CBRAs in the R17 version is determined as the RO configuration information in the RO resource information of the triggered 2-step CBRA.

[0173] In one embodiment, the specified version may include the legacy version and the R17 version. Since different CBRA configuration information can be configured for different features in the R17 version, the terminal can be configured with RO resource information for multiple 2-step CBRAs in the R17 version.

[0174] In this scenario, the terminal can determine the RO configuration information in a portion (which can be one or more) of the resource information from the legacy version's 2-step CBRA and the RO resource information from multiple 2-step CBRAs in the R17 version as the RO configuration information in the triggered 2-step CFRA; alternatively, it can determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0175] Specifically, when the terminal determines the RO configuration information in a portion of the RO resource information in at least multiple 2-step CBRAs of R17 as the RO configuration information in the triggered 2-step CBRA, the portion of the resource information can be determined based on a predefined list of 2-step CBRA configuration information in R17. For example, multiple RO configuration information can be arranged in order in the list, and the portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0176] In addition, the terminal determines the RO configuration information in the total resource information as the RO configuration information in the triggered 2-step CFRA, which means that the RO configured in the total resource information is available to the terminal.

[0177] In one embodiment, determining the RO configuration information in some or all of the resource information in the legacy version of the 2-step CBRA and the RO resource information of multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CBRA includes:

[0178] When receiving an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version 2-step CBRA and the RO resource information of the R17 version 2-step CBRA, the RO configuration information in some or all of the resource information in the legacy version 2-step CBRA and the multiple RO resource information of the R17 version 2-step CBRA is determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0179] The method further includes:

[0180] If no instruction is received from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version of the 2-step CBRA and the RO resource information of the R17 version of the 2-step CBRA, the RO configuration information in the RO resource information of the triggered 2-step CFRA is determined based on the RO resource information of the legacy version of the 2-step CBRA.

[0181] In one embodiment, the terminal can determine, based on instructions from the network-side device, whether to determine the RO configuration information in some or all of the RO resource information in the legacy version's 4-step CBRA and the RO resource information of multiple 2-step CBRAs in the R17 version as the RO configuration information in the triggered 2-step CFRA.

[0182] For example, when receiving an instruction from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version of the 2-step CBRA and the RO resource information of the R17 version of the 2-step CBRA, the RO configuration information in some or all of the resource information in the legacy version of the 2-step CBRA and the multiple RO resource information of the R17 version of the 2-step CBRA can be determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0183] If no instruction is received from the network-side device to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version 2-step CBRA and the RO resource information of the R17 version 2-step CBRA, then the RO configuration information of the triggered 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the legacy version 2-step CBRA.

[0184] In one embodiment, determining the RO configuration information in some or all of the resource information in the legacy version of the 2-step CBRA and the RO resource information of multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CBRA includes:

[0185] When the terminal supports determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in version R17, the RO configuration information in some or all of the resource information in the legacy version of the 2-step CBRA and the RO resource information of multiple 2-step CBRAs in version R17 will be determined as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0186] The method further includes:

[0187] When the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CFRA in version R17, the RO configuration information of the triggered 2-step CFRA is determined based on the RO configuration information in the RO resource information of the legacy version of 2-step CFRA.

[0188] In one embodiment, the terminal may determine, based on its own capabilities, whether to identify the RO configuration information in some or all of the resource information in the legacy version's 2-step CBRA and the RO resource information of multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0189] For example, if it has the capability to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in version R17, it can determine the RO configuration information in some or all of the resource information in the legacy version of the 2-step CBRA and the RO resource information of multiple 2-step CBRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0190] If the system's own capabilities do not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in version R17, it can determine the RO configuration information of the triggered 2-step CFRA based solely on the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA.

[0191] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The terminal can determine which features it supports. When the terminal determines the RO resource information of the triggered 2-step CFRA based at least on the RO resource information of the 2-step CFRA in R17, the terminal can determine one or more 2-step CBRA RO resource information corresponding to the supported features from multiple 2-step CBRA RO resource information sets in R17, and then determine the RO configuration information in the triggered 2-step CFRA RO resource information from the determined one or more 2-step CBRA RO resource information.

[0192] For example, if the network-side device configures the RO resource information for four 2-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and the terminal's capability only supports the CE and Redcap features, then the terminal can determine the RO resource information for the two 2-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 2-step CBRAs in R17 version, and then determine the RO configuration information in the RO resource information of the triggered 2-step CBRA from the determined RO resource information of the two 2-step CBRAs.

[0193] In one embodiment, determining the RO configuration information in some or all of the RO resource information of the multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0194] Based on the RO resource information of the legacy version of the 2-step CBRA and the RO resource information of multiple 2-step CBRAs in the R17 version, the RO configuration information in some or all of the resource information is determined as the RO configuration information in the RO resource information of the triggered 2-step CBRA.

[0195] For example, the terminal itself can determine the RO configuration information in some or all of the resource information in the legacy version's 2-step CBRA and the RO resource information of multiple 2-step CBRAs in the R17 version as the RO configuration information in the triggered 2-step CFRA.

[0196] For example, the terminal itself can implement this by only needing to determine the RO configuration information in some or all of the RO resource information in multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0197] For example, the terminal itself can determine the RO configuration information in the RO resource information of the triggered 2-step CFRA based solely on the RO resource information of the legacy version's 2-step CBRA.

[0198] Figure 10 This is a schematic flowchart illustrating yet another method for determining random access timing resource information according to embodiments of this disclosure. Figure 10 As shown, when no independent random access opportunity (RO) resource information is configured for the terminal in the CFRA configuration information, determining the RO resource information for the triggered 2-step CFRA based on the RO resource information of the specified version of contention-based random access CBRA further includes:

[0199] In step S1001, the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA is determined.

[0200] In one embodiment, since the RO resource information of the 2-step CFRA includes two parts: RO configuration information and the correspondence between SSB and RO, in addition to determining the RO configuration information in the RO resource information of the 2-step CFRA, it is also necessary to determine the correspondence between SSB and RO in the RO resource information of the 2-step CFRA. Then, the terminal can determine the RO where the 2-step CFRA is performed based on the determined RO configuration information and the correspondence between SSB and RO.

[0201] In one embodiment, determining the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA includes:

[0202] The correspondence between the synchronization signal block SSB and RO in the RO resource information of the specified version of the 2-step CBRA is determined as the correspondence between the SSB and RO in the RO resource information of the triggered 2-step CFRA.

[0203] After determining the RO configuration information in the RO resource information of the specified version of CBRA as the RO configuration information of the triggered 2-step CFRA based on the aforementioned embodiments, the terminal can further determine the correspondence between the synchronization signal block SSB and RO in the RO resource information of the specified version of CBRA as the correspondence between the SSB and RO in the RO resource information of the triggered 2-step CFRA. That is, the RO configuration information and the correspondence between SSB and RO can belong to the same RO resource information.

[0204] In one embodiment, determining the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA includes:

[0205] Based on the correspondence between the synchronization signal block SSB and RO in the RO resource information of all versions of the 2-step CFRA pre-configured by the network-side device to the terminal, the correspondence between the SSB and RO in the RO resource information of the triggered 2-step CFRA is determined.

[0206] After determining the RO configuration information in the RO resource information of the specified version of CBRA as the RO configuration information of the triggered 2-step CFRA based on the aforementioned embodiments, the terminal can determine the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA according to the correspondence between SSB and RO in the RO resource information of all versions of CBRA pre-configured to the terminal by the network-side device (not necessarily limited to the RO resource information of the specified version of CBRA).

[0207] It should be noted that when there are multiple correspondences between SSBs and ROs in the RO resource information of all versions of CBRA pre-configured to the terminal by the network-side device, the terminal can determine one correspondence between SSBs and ROs. The correspondence between SSBs and ROs is represented by a numerical value, such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16, etc. The terminal can select one of the numerical values, such as the maximum or minimum value.

[0208] In one embodiment, determining the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA includes:

[0209] The correspondence between SSB and RO in the RO resource information of the two-step CFRA triggered by the terminal is determined.

[0210] The following embodiments describe, from the network side, how a terminal determines the RO resource information of a triggered 2-step CFRA when indicated by a network-side device. It should be noted that network-side device indication is only one way for the terminal to determine the RO resource information of a triggered 2-step CFRA based on the random access timing RO resource information of a specified version of the CBRA. The terminal can also determine the RO resource information of a triggered 2-step CFRA based on the random access timing RO resource information of a specified version of the CBRA according to the protocol agreement.

[0211] Figure 11This is a schematic flowchart illustrating a method for indicating random access timing resource information according to an embodiment of this disclosure. The method for indicating random access timing resource information shown in this embodiment can be executed by a network-side device, which can communicate with a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The network-side device includes, but is not limited to, network-side devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0212] like Figure 11 As shown, the method for indicating random access timing resource information may include the following steps:

[0213] In step S1101, the terminal is triggered to perform a 2-step non-contention random access CFRA.

[0214] In step S1102, if there is no independently configured random access opportunity (RO) resource information for the terminal in the CFRA configuration information, the terminal is instructed to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the specified version of the contention random access CBRA.

[0215] In one embodiment, the network-side device may trigger the terminal to perform a 2-step CFRA under certain circumstances, wherein the 2-step CFRA is triggered by a switching Handover command.

[0216] After the network-side device triggers the terminal to perform a 2-step CFRA, the terminal needs to determine the RO resource information for the 2-step CFRA. For example, it needs to determine whether there is RO resource information configured independently for the terminal in the CFRA configuration information. If there is RO resource information configured independently for the terminal, the terminal can determine the RO for initiating the 2-step CFRA based on the RO resource information configured independently for the terminal. If there is no RO resource information configured independently for the terminal, the terminal can determine the RO resource information for the triggered 2-step CFRA based on the RO resource information of the CBRA.

[0217] According to embodiments of this disclosure, the network-side device can instruct the terminal to determine the RO resource information for the triggered two-step CFRA based on the RO resource information of a specified version of CBRA. Therefore, even if the terminal is configured with RO resource information of both legacy and R17 versions of CBRA, the terminal can accurately determine which version of CBRA's RO resource information to use to determine the triggered two-step CFRA's RO resource information. This avoids the technical problem of the terminal struggling to determine which version of CBRA's RO resource information to use when faced with multiple versions of CBRA's RO resource information.

[0218] In one embodiment, when the CFRA configuration information does not include independent random access timing (RO) resource information for the terminal, instructing the terminal to determine the triggered 2-step CFRA RO resource information based on the specified version of contention-based random access CBRA RO resource information includes:

[0219] If no independent RO resource information is configured for the terminal in the CFRA configuration information, but multiple CBRA RO resource information has been configured for the terminal, the RO resource information of the target CBRA among the multiple CBRA RO resource information is indicated as the RO resource information of the triggered 2-step CFRA.

[0220] When the network-side device configures RO resource information of multiple CBRAs for the terminal, in addition to instructing the terminal to randomly access the RO resource information of the CBRA according to the specified version of the contention and determine the RO resource information of the triggered 2-step CFRA, it can also more precisely instruct the terminal to use the RO resource information of the target CBRA among the multiple CBRA RO resource information as the RO resource information of the triggered 2-step CFRA.

[0221] In one embodiment, the designated version includes at least one of the following: a legacy version and R17 version. In one embodiment, the legacy version includes at least one of the following: R15 version and R16 version.

[0222] In one embodiment, the RO resource information includes at least one of the following:

[0223] RO configuration information;

[0224] The correspondence between the synchronization signal block SSB and RO.

[0225] In one embodiment, the RO resource information may include two parts: RO configuration information and the correspondence between SSB and RO. The terminal determines the RO resource information of the triggered 2-step CFRA based on the RO resource information of the specified version of the contention-based random access CBRA. This includes two corresponding cases: one is to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA, and the other is to determine the correspondence between SSB and RO in the RO resource information of the 2-step CFRA.

[0226] Correspondingly, the CFRA configuration information does not include the random access timing (RO) resource information configured independently for the terminal. This includes two cases: one is that only the RO configuration information is missing in the RO resource information; the other is that the entire RO resource information is missing.

[0227] If only the RO configuration information is missing in the RO resource information, the terminal needs to be instructed to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA. For example, the RO configuration information in the RO resource information of the triggered 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the 2-step CFRA.

[0228] When all RO resource information is set to default, the terminal needs to be instructed to determine the RO configuration information and the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA. For example, the RO configuration information in the RO resource information of the triggered 2-step CFRA can be determined based on the RO configuration information in the 4-step CBRA. The process of instructing the terminal to determine the correspondence between SSB and RO will be explained in subsequent embodiments.

[0229] The following examples illustrate how to instruct the terminal to determine the RO configuration information in the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA.

[0230] Figure 12 This is a schematic flowchart illustrating another method for indicating random access timing resource information according to embodiments of the present disclosure. Figure 12 As shown, the RO resource information includes RO configuration information. When the CFRA configuration information does not include RO resource information for the terminal under independent random access timing, the RO resource information for the triggered 2-step CFRA is determined based on the RO resource information of the specified version of contention-based random access CBRA, including:

[0231] In step S1201, if no independent RO configuration information is configured for the terminal in the CFRA configuration information, the terminal is instructed to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO resource information in the triggered 2-step CFRA.

[0232] In one embodiment, the RO resource information includes RO configuration information, that is, the CFRA configuration information does not include RO resource information independently configured for the terminal, or at least includes RO configuration information in the CFRA configuration information that is not independently configured for the terminal.

[0233] In this scenario, the network-side device can instruct the terminal to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0234] Figure 13This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 13 As shown, the instruction to the terminal to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0235] In step S1301, the terminal is instructed to determine the RO configuration information in the RO resource information of the legacy version's 4-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0236] In one embodiment, the specified version can be a legacy version. In this case, the network-side device can instruct the terminal to determine the RO configuration information in the RO resource information of the 4-step CBRA of the legacy version as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0237] Figure 14 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 14 As shown, the instruction to the terminal to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0238] In step 1401, the terminal is instructed to determine the RO configuration information in some or all of the RO resource information in the multiple 4-step CBRA RO resource information of R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0239] In one embodiment, the specified version can be R17. Since different CBRA configuration information can be configured for different features in R17, the terminal can be configured with RO resource information for multiple 4-step CBRAs in R17.

[0240] In this scenario, the network-side device can instruct the terminal to determine the RO configuration information in a portion (which may be one or more) of the RO resource information in multiple 4-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA; alternatively, it can instruct the terminal to determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0241] Specifically, the network-side device instructs the terminal to determine the RO configuration information in a portion of the RO resource information in multiple 4-step CBRAs of R17 as the RO configuration information in the triggered 2-step CFRA. The portion of the resource information can be determined based on a predefined list of 4-step CBRA configuration information in R17. For example, multiple RO configuration information can be arranged in order in the list. The portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0242] In addition, when the network-side device instructs the terminal to determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA, it means that the RO configured in the RO configuration information in all resource information is available to the terminal.

[0243] In one embodiment, instructing the terminal to determine the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0244] The terminal is instructed to determine the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA.

[0245] In one embodiment, when the network-side device instructs the terminal to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in R17, the terminal, upon receiving the instruction, can determine the RO configuration information in some or all of the RO resource information of the multiple 4-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA.

[0246] If the network-side device does not instruct the terminal to determine the RO configuration information in the triggered 2-step CFRA RO resource information based on the RO configuration information in the 4-step CBRA RO resource information of the legacy version, the terminal can determine the RO configuration information in the triggered 2-step CFRA RO resource information based on the RO configuration information in the 4-step CBRA RO resource information of the legacy version.

[0247] In one embodiment, instructing the terminal to determine the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0248] When the terminal supports determining the RO configuration information in the triggered 2-step CFRA RO resource information based on the RO configuration information in the 4-step CBRA RO resource information of R17 version, the terminal is instructed to determine the RO configuration information in some or all of the RO resource information in the multiple 4-step CBRA RO resource information of R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0249] The method further includes:

[0250] If the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, the terminal is instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA in the legacy version.

[0251] In one embodiment, the network-side device can determine, based on the terminal's capabilities, whether the terminal supports determining the RO configuration information in some or all of the RO resource information in multiple 4-step CBRAs of R17 as the RO resource information in the triggered 2-step CFRA.

[0252] For example, when it is determined that the terminal supports determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in R17, the terminal can be instructed to determine the RO configuration information in some or all of the RO resource information of the multiple 4-step CBRAs in R17 as the RO configuration information in the triggered 2-step CFRA.

[0253] If it is determined that the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, the terminal can be instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the legacy version of the 4-step CBRA.

[0254] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The network-side device can determine the features supported by the terminal based on its capabilities. Then, the network-side device can determine the RO resource information of one or more 4-step CBRAs corresponding to the supported features from the RO resource information of multiple 4-step CBRAs in Release 17, and subsequently instruct the terminal to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the determined RO resource information of one or more 4-step CBRAs.

[0255] For example, if the network-side device configures the RO resource information for four 4-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and it is determined that the terminal only supports the CE and Redcap features, then the terminal is instructed to determine the RO resource information for the two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 4-step CBRAs in R17 version, and then determine the RO configuration information in the RO resource information of the two 4-step CBRAs that are determined to trigger the 2-step CBRA.

[0256] Figure 15 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 15 As shown, the instruction to the terminal to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0257] In step S1501, the terminal is instructed to determine the RO configuration information in some or all of the RO resource information in the legacy version's 4-step CBRA and the multiple 4-step CBRA RO resource information in the R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0258] In one embodiment, the specified version may include the legacy version and the R17 version. Since different CBRA configuration information can be configured for different features in the R17 version, the terminal can be configured with RO resource information for multiple 4-step CBRAs in the R17 version.

[0259] In this scenario, the network-side device can instruct the terminal to determine the RO configuration information in a portion (which may be one or more) of the RO resource information in the legacy version's 4-step CBRA and the RO resource information in multiple 4-step CBRAs of the R17 version as the RO configuration information in the triggered 2-step CFRA; alternatively, it can instruct the terminal to determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0260] Specifically, when the terminal is instructed to determine the RO configuration information in a portion of the RO resource information in at least one of the multiple 4-step CBRA RO resource information in R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information, the portion of the resource information can be determined based on a predefined list of 4-step CBRA configuration information in R17. For example, multiple RO configuration information can be arranged in order in the list, and the portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0261] In addition, instructing the terminal to determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA means that the RO configured in the RO configuration information in all resource information is available to the terminal.

[0262] In one embodiment, when the network-side device instructs the terminal to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version's 4-step CBRA and the R17 version's 4-step CBRA, the terminal can, according to the instruction, determine the RO configuration information in some or all of the resource information from the legacy version's 4-step CBRA and the multiple 4-step CBRA RO resource information of the R17 version as the RO configuration information in the triggered 2-step CFRA.

[0263] If the network-side device does not instruct the terminal to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version's 4-step CBRA and the R17 version's 4-step CBRA, the terminal can determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the legacy version's 4-step CBRA.

[0264] In one embodiment, instructing the terminal to determine the RO configuration information in some or all of the RO resource information in the legacy version's 4-step CBRA and the RO resource information of multiple 4-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0265] When the terminal supports determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, the terminal is instructed to determine the RO configuration information in some or all of the resource information in the RO resource information of the legacy version of the 4-step CBRA and the RO resource information of multiple 4-step CBRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0266] The method further includes:

[0267] When the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 4-step CBRA in version R17, the terminal is instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA in the legacy version.

[0268] In one embodiment, the network-side device can determine, based on the terminal's capabilities, whether the terminal supports determining the RO configuration information in some or all of the resource information in the legacy version's 4-step CBRA RO resource information and the RO resource information in multiple 4-step CBRAs of the R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0269] For example, if the terminal's capabilities determine that it supports the RO resource information of the triggered 2-step CFRA based on the 4-step CBRA of version R17, the terminal can be instructed to determine the RO configuration information in some or all of the resource information in the legacy version's 4-step CBRA and multiple 4-step CBRAs of version R17 as the RO configuration information in the triggered 2-step CFRA.

[0270] When it is determined that the terminal does not support the RO resource information of the triggered 4-step CFRA based on the 4-step CBRA of the R17 version, the terminal can be instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the 4-step CBRA of the legacy version.

[0271] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The network-side device can determine the features supported by the terminal based on its capabilities. When the terminal determines the RO resource information for a triggered 2-step CFRA based at least on the RO resource information of the 4-step CFRA in Release 17, the network-side device can determine one or more 4-step CBRA RO resource information corresponding to the features supported by the terminal from among the multiple 4-step CBRA RO resource information in Release 17, and then instruct the terminal to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA from the determined RO resource information of the one or more 4-step CBRA.

[0272] For example, if the network-side device configures the RO resource information for four 4-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and it is determined that the terminal only supports CE and Redcap, then the RO resource information for the two 4-step CBRAs corresponding to the CE and Redcap features can be determined from the RO resource information of the four 4-step CBRAs in R17 version. Then, the terminal is instructed to determine the RO configuration information in the RO resource information of the two 4-step CBRAs that are determined as the triggered 2-step CFRA.

[0273] Figure 16 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 16 As shown, the RO resource information includes RO configuration information and the corresponding relationship. When the CFRA configuration information does not configure independent random access timing RO resource information for the terminal, the terminal is instructed to determine the triggered 2-step CFRA RO resource information based on the specified version of the contention-based random access CBRA RO resource information, including:

[0274] In step S1601, if the terminal is not configured with an independent RO configuration and the corresponding relationship in the CFRA configuration information, the terminal is instructed to randomly access the RO resource information of the CBRA in the specified version of the two-step contention, and determine the RO configuration information in the RO resource information of the triggered two-step CFRA.

[0275] In one embodiment, if the RO resource information includes RO configuration information and the corresponding relationship, that is, if the CFRA configuration information does not contain an RO configuration and the corresponding relationship configured independently for the terminal, the network-side device instructs the terminal to determine the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0276] Figure 17 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 17 As shown, the instruction to the terminal to determine the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0277] In step S1701, the terminal is instructed to determine the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0278] In one embodiment, the specified version can be a legacy version. In this case, the network-side device can instruct the terminal to determine the RO configuration information in the RO resource information of the legacy version's 2-step CBRA as the RO configuration information in the triggered 2-step CFRA.

[0279] Figure 18 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 18 As shown, the instruction to the terminal to determine the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0280] In step S1801, the terminal is instructed to determine the RO configuration information in some or all of the RO resource information in the multiple 2-step CBRAs of R17 version as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0281] In one embodiment, the specified version can be R17. Since different CBRA configuration information can be configured for different features in R17, the terminal can be configured with RO resource information for multiple 2-step CBRAs in R17.

[0282] In this scenario, the network-side device can instruct the terminal to determine the RO configuration information in a portion (which may be one or more) of the RO resource information in multiple 2-step CBRAs in Release 17 as the RO configuration information in the triggered 2-step CFRA; alternatively, it can instruct the terminal to determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0283] Specifically, the terminal is instructed to identify the RO configuration information in a subset of the RO resource information from multiple 2-step CBRAs in R17 as the RO configuration information for the triggered 2-step CBRA. This subset of resource information can be based on a predefined list of 2-step CBRA configuration information for R17.

[0284] To determine, for example, by arranging multiple RO configuration information in a list in order, the aforementioned resource information can be...

[0285] It consists of the first n configuration items in the list, where n is an integer greater than or equal to 1.

[0286] In addition, instructing the terminal to determine the RO configuration information in the total resource information as the RO configuration information in the triggered 2-step CFRA means that the RO configured in the total resource information is available to the terminal.

[0287] In one embodiment, when the network-side device instructs the terminal to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in R17, the terminal can, according to the instruction, determine the RO configuration information in some or all of the RO resource information of the multiple 2-step CBRAs in R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0288] When the network-side device does not instruct the terminal to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA, the terminal can determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the legacy version of the 2-step CBRA.

[0289] In one embodiment, instructing the terminal to determine the RO configuration information in some or all of the RO resource information in multiple 2-step CBRAs of R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0290] When the terminal supports determining the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the 2-step CFRA of R17 version, the terminal is instructed to determine the RO configuration information in some or all of the RO resource information of the multiple 2-step CFRAs of R17 version as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0291] The method further includes:

[0292] If the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CFRA in version R17, the terminal is instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the legacy version 2-step CFRA.

[0293] In one embodiment, the network-side device can determine, based on the terminal's capabilities, whether the terminal supports identifying the RO configuration information in some or all of the RO resource information in multiple 2-step CBRAs in Release 17 as the RO resource information in the triggered 2-step CFRA.

[0294] For example, if the terminal's capabilities determine that it supports the RO resource information of the 2-step CBRA in version R17, and the RO resource information of the triggered 2-step CFRA is determined, the terminal can be instructed to determine the RO configuration information in some or all of the RO resource information of multiple 2-step CBRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0295] If, based on the terminal's capabilities, it is determined that the terminal does not support determining the RO resource information of the triggered 2-step CFRA according to the RO resource information of the 2-step CBRA in version R17, then the terminal can be instructed to determine the RO configuration information of the triggered 2-step CFRA according to the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA.

[0296] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The network-side device can determine the features supported by the terminal based on its capabilities. Then, the network-side device can determine the RO resource information for one or more 2-step CBRAs corresponding to the features supported by the terminal from the RO resource information of multiple 2-step CBRAs in Release 17, and subsequently instruct the terminal to configure the RO configuration information in the RO resource information of the 2-step CBRA that is determined to be triggered by the determined RO resource information of one or more 2-step CBRAs.

[0297] For example, if the network-side device configures the RO resource information for four 2-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and the network-side device determines that the terminal only supports the CE and Redcap features, then the network-side device can determine the RO resource information for the two 2-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 2-step CBRAs in R17 version, and then instruct the terminal to determine the RO configuration information in the RO resource information of the triggered 2-step CBRA in the determined 2-step CBRAs.

[0298] Figure 19 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 19 As shown, the instruction to the terminal to determine the RO configuration information in the RO resource information of the specified version of the 2-step CBRA as the RO configuration information in the triggered 2-step CFRA includes:

[0299] In step S1901, the terminal is instructed to determine the RO configuration information in some or all of the RO resource information in the legacy version of the 2-step CBRA and the multiple 2-step CBRA RO resource information in the R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0300] In one embodiment, the specified version may include the legacy version and the R17 version. Since different CBRA configuration information can be configured for different features in the R17 version, the terminal can be configured with RO resource information for multiple 2-step CBRAs in the R17 version.

[0301] In this scenario, the network-side device can instruct the terminal to determine the RO configuration information in a portion (which may be one or more) of the resource information in the legacy version of the 2-step CBRA and the RO resource information in multiple 2-step CBRAs in the R17 version as the RO configuration information in the triggered 2-step CFRA; alternatively, it can determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA.

[0302] Specifically, when the terminal is instructed to determine the RO configuration information in a portion of the RO resource information in at least one of the multiple 2-step CBRA RO resource information in R17 version as the RO configuration information in the triggered 2-step CBRA RO resource information, the portion of the resource information can be determined based on a predefined list of 2-step CBRA configuration information in R17. For example, multiple RO configuration information can be arranged in order in the list, and the portion of the resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0303] In addition, instructing the terminal to determine the RO configuration information in all resource information as the RO configuration information in the triggered 2-step CFRA means that the RO configured in the RO configuration information in all resource information is available to the terminal.

[0304] In one embodiment, when the network-side device instructs the terminal to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version of the 2-step CBRA and the RO resource information of the R17 version of the 2-step CBRA, the terminal may, according to the instruction, determine the RO configuration information in some or all of the resource information from the legacy version of the 2-step CBRA and the multiple RO resource information of the R17 version as the RO configuration information in the triggered 2-step CFRA.

[0305] If the network-side device does not instruct the terminal to determine the RO resource information of the triggered 2-step CFRA based on the RO resource information of the legacy version 2-step CBRA and the RO resource information of the R17 version 2-step CBRA, the terminal can determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the legacy version 2-step CBRA RO resource information.

[0306] In one embodiment, instructing the terminal to determine the RO configuration information in some or all of the RO resource information in the legacy version's 2-step CBRA and the RO resource information of multiple 2-step CBRAs in R17 version as the RO configuration information in the triggered 2-step CFRA includes:

[0307] When the terminal supports determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CFRA in version R17, the terminal is instructed to determine the RO configuration information in some or all of the resource information in the RO resource information of the legacy version of 2-step CFRA and the RO resource information of multiple 2-step CFRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0308] The method further includes:

[0309] When the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CFRA in version R17, the terminal is instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the legacy version of 2-step CFRA.

[0310] In one embodiment, the network-side device determines, based on the terminal's capabilities, whether the terminal supports determining the RO configuration information in some or all of the resource information in the legacy version's 2-step CBRA RO resource information and the multiple 2-step CBRA RO resource information in the R17 version as the RO configuration information in the triggered 2-step CFRA RO resource information.

[0311] For example, when it is determined that the terminal supports determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in version R17, the terminal can be instructed to determine the RO configuration information in some or all of the resource information in the RO resource information of the legacy version of 2-step CBRA and the RO resource information of multiple 2-step CBRAs in version R17 as the RO configuration information in the RO resource information of the triggered 2-step CFRA.

[0312] When it is determined that the terminal does not support determining the RO resource information of the triggered 2-step CFRA based on the RO resource information of the 2-step CBRA in version R17, the terminal can be instructed to determine the RO configuration information of the triggered 2-step CFRA based on the RO configuration information in the RO resource information of the legacy version of the 2-step CBRA.

[0313] In one embodiment, the terminal's capabilities may further include its support for features such as Slicing, SDT, CE, and Redcap. The network-side device can determine the features supported by the terminal based on its capabilities. When instructing the terminal to determine the RO resource information of the triggered 2-step CFRA based at least on the RO resource information of the 2-step CFRA in Release 17, the network-side device can determine one or more 2-step CBRA RO resource information corresponding to the supported features from among the multiple 2-step CBRA RO resource information in Release 17, and then instruct the terminal to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA from the determined one or more 2-step CBRA RO resource information.

[0314] For example, if the network-side device configures the RO resource information for four 2-step CBRAs in R17 version for the terminal for the four features Slicing, SDT, CE, and Redcap, and the network-side device determines that the terminal only supports the CE and Redcap features, then the network-side device can determine the RO resource information for the two 2-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four 2-step CBRAs in R17 version, and then instruct the terminal to determine the RO configuration information in the RO resource information of the triggered 2-step CBRA in the determined 2-step CBRAs.

[0315] Figure 20 This is a schematic flowchart illustrating yet another method for indicating random access timing resource information according to embodiments of this disclosure. Figure 20 As shown, when no independent random access opportunity (RO) resource information is configured for the terminal in the CFRA configuration information, instructing the terminal to determine the triggered 2-step CFRA RO resource information based on the specified version of the contention-based random access CBRA RO resource information further includes:

[0316] In step S2001, the terminal is instructed to determine the correspondence between SSB and RO in the RO resource information of the triggered 2-step CFRA in a specified manner.

[0317] In one embodiment, the network side needs to instruct the terminal to determine the RO configuration information in the RO resource information of the triggered 2-step CFRA based on the RO resource information of the specified version of CBRA. For example, the RO configuration information in the RO resource information of the specified version of CBRA can be determined as the RO configuration information of the RO resource information of the triggered 2-step CFRA.

[0318] In order for the terminal to determine the RO for the 2-step CFRA, it needs to determine not only the RO configuration information but also the correspondence between SSBs and ROs. Therefore, the network-side device needs to further instruct the terminal to determine the correspondence between SSBs and ROs in the RO resource information of the triggered 2-step CFRA. Specifically, the terminal can be instructed to determine the correspondence between SSBs and ROs in the RO resource information of the triggered 2-step CFRA in a specified manner. Only then can the terminal determine the RO used for the triggered 2-step CFRA based on the RO configuration information and the aforementioned correspondence.

[0319] In one embodiment, the specifying method includes at least one of the following:

[0320] The correspondence between the synchronization signal block SSB and RO in the RO resource information of the specified version of the 2-step CBRA is determined as the correspondence between the SSB and RO in the RO resource information of the triggered 2-step CFRA.

[0321] Based on the correspondence between the synchronization signal block SSB and RO in the RO resource information of all versions of the 2-step CFRA pre-configured by the network-side device to the terminal, the correspondence between the SSB and RO in the RO resource information of the triggered 2-step CFRA is determined.

[0322] In one embodiment, after the network-side device instructs the terminal, based on the aforementioned embodiment, to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information of the triggered 4-step CFRA, it can further instruct the terminal to determine the correspondence between the synchronization signal block SSB and RO in the RO resource information of the specified version of the 4-step CBRA as the correspondence between the SSB and RO in the triggered 4-step CFRA. That is, the RO configuration information and the correspondence between the SSB and RO can belong to the same RO resource information.

[0323] In one embodiment, after instructing the terminal, based on the foregoing embodiment, to determine the RO configuration information in the RO resource information of the specified version of the 4-step CBRA as the RO configuration information of the triggered 4-step CFRA, the network-side device may instruct the terminal to determine the correspondence between SSB and RO in the RO resource information of the triggered 4-step CFRA according to the correspondence between SSB and RO in the RO resource information of all versions of the 4-step CBRA pre-configured to the terminal (not necessarily limited to the RO resource information of the specified version of the 4-step CBRA).

[0324] It should be noted that when there are multiple correspondences between SSBs and ROs in the RO resource information of all versions of the 4-step CBRA pre-configured to the terminal by the network-side device, the terminal can be instructed to determine one of the correspondences between SSBs and ROs. The correspondence between SSBs and ROs is represented by a numerical value, such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16, etc. The network-side device can select one of the values ​​to indicate to the terminal, such as selecting the maximum or minimum value.

[0325] Embodiments of this disclosure also propose a non-contention-based random access configuration method, executed by a network-side device, the method comprising:

[0326] If a specified version of the 2-step contention-based random access (CBRA) resource is configured on the bandwidth portion (BWP) selected by the terminal, configure the 2-step non-contention-based random access (CFRA) resource.

[0327] In one embodiment, if the network-side device configures the terminal to perform 2-step CFRA resources on the BWP selected by the terminal, and the terminal's 2-step CFRA resources cannot be used for some reason (e.g., by default), then the terminal needs to use the 2-step CBRA resources to perform 2-step CFRA. However, if the 2-step CBRA resources are not configured on the BWP, the terminal will not be able to use the 2-step CBRA resources to perform 2-step CFRA, which will seriously affect the communication effect.

[0328] Therefore, based on embodiments of this disclosure, two-step non-contention random access (CFRA) resources are configured only if a specified version of two-step contention-based random access (CBRA) resources is configured on the bandwidth portion (BWP) selected by the terminal. This ensures that even if the two-step CFRA resources are unavailable, the terminal can still successfully use the two-step CBRA resources for two-step CFRA, guaranteeing the smooth execution of two-step CFRA.

[0329] If the specified version of the 2-step contention-based random access (CBRA) resource is not configured on the bandwidth portion of the BWP selected by the terminal, then the 2-step non-contention-based random access (CFRA) resource does not need to be configured.

[0330] In one embodiment, the specified version is determined according to instructions from the network-side device or according to a protocol agreement.

[0331] In one embodiment, the designated version includes at least one of the following: a legacy version and R17 version. In one embodiment, the legacy version includes at least one of the following: R15 version and R16 version.

[0332] Embodiments of this disclosure also propose a non-contention-based random access configuration method, executed by a network-side device, the method comprising:

[0333] If the specified version of the 4-step contention random access CBRA resource is not configured on the bandwidth portion BWP selected by the terminal, or if the specified version of the 4-step CBRA resource is configured on the BWP and the specified version of the 4-step CBRA resource is not shared, configure the RO configuration information in the resource information of the 2-step CFRA.

[0334] In one embodiment, since the RO configuration information in the 2-step CFRA resource information is defaulted, the terminal needs to use the RO configuration information in the 4-step CBRA resource information. If the specified version of the 4-step CBRA resource is not configured on the bandwidth portion BWP selected by the terminal, or if the specified version of the 4-step CBRA resource is configured on the BWP but the specified version of the 4-step CBRA resource is not shared, then the terminal cannot use the RO configuration information in the 4-step CBRA resource information for 2-step CFRA, which seriously affects the communication performance.

[0335] Therefore, based on the embodiments of this disclosure, when the specified version of the 4-step contention-based random access (CBRA) resource is not configured on the bandwidth portion (BWP) selected by the terminal, or when the specified version of the 4-step CBRA resource is configured on the BWP and the specified version of the 4-step CBRA resource is not shared, the RO configuration information in the resource information of the 2-step CFRA must be configured. Accordingly, when the terminal cannot use the configuration information in the 4-step CBRA resource information to perform 2-step CFRA, CFRA can be performed according to the RO configuration information in the configured 2-step CFRA resource information, ensuring that 2-step CFRA can proceed smoothly.

[0336] In one embodiment, the specified version is determined according to instructions from the network-side device or according to a protocol agreement.

[0337] In one embodiment, the designated version includes at least one of the following: a legacy version and R17 version. In one embodiment, the legacy version includes at least one of the following: R15 version and R16 version.
