Description

[Technical field]

[0001] The present disclosure relates to the field of communication technologies, and in particular to a method for determining random access occasion resource information, a method for indicating random access occasion resource information, a non-contention random access configuration method, a device for determining random access occasion resource information, a device for indicating random access occasion resource information, a non-contention random access configuration device, a communication device, and a computer-readable storage medium. [Background technology]

[0002] In some scenarios, the terminal can initiate random access. If the random access is divided by steps, it can include two-step random access and four-step random access, and if the random access is divided by contention type, it can include contention-based random access (CBRA) and non-contention random access (Contention-Free Random Access (CFRA)).

[0003] For the case of two-step CFRA, after the two-step CFRA is initiated, the terminal needs to start the two-step CFRA on a random access occasion, which may also be called a physical random access channel occasion (PRACH occasion, RO), so the terminal needs to first determine the RO resource information for the two-step CFRA.

[0004] However, in some cases, the network side does not indicate the RO resource in the CFRA configuration information, in which case the terminal can use the RO resource 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 are also expanded. In order to adapt to the features of different scenarios, different CBRA configuration information can be configured for different features. Therefore, a terminal can be configured with multiple CBRA configuration information. As a result, if the terminal does not determine the RO resource information in the CFRA configuration information, it becomes difficult to determine which RO resource in the CBRA configuration information to use for the CFRA.

[0021] The technical solutions in the embodiments of the present disclosure will be described below in detail and completely with reference to the drawings of the embodiments of the present disclosure, but it is clear that the described embodiments are not all the embodiments but only some of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without any creative labor belong to the scope of protection of the present disclosure.

[0022] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure. The singular forms "a" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. In addition, the term "and / or" as used herein refers to any or all possible combinations of one or more of the associated listed items.

[0023] In the embodiments of the present disclosure, terms such as first, second, third, etc. may be used to describe various pieces of information, but it should be understood that these pieces of information should not be limited to these terms. These terms are merely used to distinguish between the same types of information. For example, the first piece of information can be referred to as the second piece of information, and similarly, the second piece of information can be referred to as the first piece of information, without departing from the scope of the embodiments of the present disclosure. Depending on the context, the word "if" as used herein can be interpreted as "when" or "in the case of" or "responsive to a determination."

[0024] For simplicity and ease of understanding, the terms "greater" or "smaller," "higher" or "lower" are used herein to express magnitude relationships. However, those skilled in the art will appreciate that the term "greater" also includes "greater than," "smaller" also includes "less than," and "higher" also includes "more than" and "lower" also includes "less than."

[0025] After the terminal initiates the two-step CFRA, it needs to start the CFRA in a random access occasion (RO) (which can also be called a physical random access channel occasion), so the terminal needs to first determine the RO resource information for the two-step CFRA.

[0026] Generally, the RO resource information of the two-step CFRA is indicated by the information element occasionsTwoStepRA in the CFRA configuration, and the information element occasionsTwoStepRA further includes the content of two parts, one part is the RO configuration information indicated by rach-ConfigGenericTwoStepRA, and another part is the correspondence between the synchronization signal block (SSB) and the RO indicated by ssb-PerRACH-OccassionTwoStepRA, and the terminal can determine the RO to initiate the two-step CFRA based on the content of these two parts.

[0027] However, in some cases, the network side does not indicate complete RO resource information in the CFRA configuration information.

[0028] For example, the entire RO resource information is not indicated, that is, the information element occasionsTwoStepRA is the default in the CFRA configuration information, in which case the terminal can use the RO resource in the two-step CBRA configuration information.

[0029] For example, the RO configuration information in the RO resource information is not indicated, that is, the information element occasions TwoStepRA in the CFRA configuration information is the default, in which case the terminal can use the RO configuration information in the RO resource information in the 4-step CBRA configuration information.

[0030] However, with the development of random communication technology, the application scenarios are also expanded. For example, in R17, in order to apply to features in different scenarios, such as features 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 CBRA RO resource information of Release 17 is configured in the terminal, and the 2-step CBRA RO resource information of Release 17 can include multiple CBRA RO resource information, for example including multiple 2-step CBRA RO resource information and multiple 4-step CBRA RO resource information.

[0031] In addition, the terminal is further configured with CBRA RO resource information of legacy releases, such as CBRA RO resource information of R15 and Release 16. In the legacy releases, the network side device does not configure different CBRA configuration information for each of the above features in the terminal, but only configures one 2-step CBRA RO resource information and one 4-step CBRA RO resource information in the terminal.

[0032] For a terminal, when the RO resource information of CBRA of legacy release and the RO resource information of CBRA of Release 17 are configured, there are RO resource information of CBRA of multiple releases for the terminal, and when faced with the RO resource information of CBRA of multiple releases, it is difficult for the terminal to determine which RO resource information of CBRA of the release is based on which to determine the RO resource information of the two-step CFRA. The following embodiments of the present disclosure are mainly proposed to solve this technical problem.

[0033] 1 is a schematic flowchart of a method for determining random access occasion resource information shown by an embodiment of the present disclosure. The method for determining random access occasion resource information shown by this embodiment is applicable to a terminal, which includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices, etc. The terminal can communicate with a network side device, which includes but is not limited to network side devices in communication systems such as 4G, 5G, 6G, etc., such as base stations, core networks, etc.

[0034] As shown in FIG. 1, the method for determining random access occasion resource information can include the following steps S101 to S102.

[0035] In step S101, a two-step non-contention random access (CFRA) is initiated.

[0036] In step S102, if there is no individual random access occasion (RO) resource information set in the CFRA configuration information for the terminal, determine the RO resource information of the initiated two-step CFRA based on the RO resource information of the contention random access (CBRA) of the specified release.

[0037] In one embodiment, the terminal may initiate a two-step CFRA in some cases, and the manner of initiating the four-step CFRA includes initiating by switching a Handover command.

[0038] After a two-step CFRA is initiated, the terminal needs to determine RO resource information of the two-step CFRA, for example, by determining whether there is RO resource information individually configured for the terminal in the CFRA configuration information. If there is RO resource information individually configured for the terminal, the terminal can determine an RO to initiate a two-step CFRA based on the RO resource information individually configured for the terminal; if there is no RO resource information individually configured for the terminal, the terminal can determine the RO resource information of the initiated two-step CFRA based on the RO resource information of a two-step CBRA or a RO resource information of a four-step CBRA.

[0039] According to the embodiment of the present disclosure, the terminal can determine the RO resource information of the initiated two-step CFRA based on the RO resource information of the CBRA of a specified release. Therefore, even if the RO resource information of the CBRA of a legacy release and the RO resource information of the CBRA of Release 17 are configured in the terminal, the terminal can accurately determine based on which RO resource information of the CBRA of a release to determine the RO resource information of the initiated two-step CFRA. When the terminal is faced with RO resource information of the CBRA of multiple releases, the technical problem that it is difficult to determine based on which RO resource information of the CBRA of a release to determine the RO resource information of the two-step CFRA is avoided.

[0040] In one embodiment, the designated release is determined based on an instruction from a network side device or is determined based on a protocol.

[0041] The terminal can determine the specified release based on an instruction from the network side device, for example, if the specified release indicated by the network side device is R17, the terminal determines RO resource information of the initiated two-step CFRA based on random access occasion (RO) resource information of the CBRA of Release 17, and for example, if the specified release indicated by the network side device is legacy, the terminal determines RO resource information of the initiated two-step CFRA based on random access occasion (RO) resource information of the CBRA of the legacy release.

[0042] The terminal may also determine the specified release based on a protocol, for example, if the specified release agreed in the protocol is R17, the terminal determines the RO resource information of the initiated two-step CFRA based on the random access occasion (RO) resource information of the CBRA of Release 17, and for example, if the specified release agreed in the protocol is legacy, the terminal determines the RO resource information of the initiated two-step CFRA based on the random access occasion (RO) resource information of the CBRA of the legacy release.

[0043] In one embodiment, the specified release includes at least one of a legacy release and Release 17. In one embodiment, the legacy release includes at least one of Release 15 and Release 16.

[0044] In one embodiment, the RO resource information includes: RO setting information, and a correspondence between a synchronization signal block (SSB) and an RO.

[0045] In one embodiment, the RO resource information may include two parts of content: RO configuration information and a correspondence relationship between an SSB and an RO. The terminal's determining the RO resource information of the initiated two-step CFRA based on the RO resource information of the designated release contention random access (CBRA) includes two corresponding cases: one is determining the RO configuration information in the RO resource information of the initiated two-step CFRA, and the other is determining the correspondence relationship between the SSB and the RO in the RO resource information of the two-step CFRA.

[0046] Accordingly, the absence of individual random access occasion (RO) resource information configured in the CFRA configuration information for the terminal also includes two cases: one is that only the RO configuration information in the RO resource information is default, and the other is that the entire RO resource information is default.

[0047] When only the RO configuration information in the RO resource information is the default, it is necessary to determine the RO configuration information in the RO resource information of the initiated two-step CFRA, for example, the RO configuration information in the RO resource information of the initiated two-step CFRA can be determined according to the RO configuration information in the RO resource information of the two-step CBRA; If the entire RO resource information is the default, it is necessary to determine the RO configuration information in the RO resource information of the initiated two-step CFRA and the correspondence between the SSB and the RO, for example, the RO configuration information in the RO resource information of the initiated two-step CFRA can be determined based on the RO configuration information in the RO resource information of the four-step CBRA. How to determine the correspondence between the SSB and the RO will be described in the following embodiment.

[0048] Hereinafter, firstly, some embodiments will be illustratively described as to how to determine RO configuration information in RO resource information of initiated 2-step CFRA based on RO configuration information in RO resource information of 4-step CBRA.

[0049] 2 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 2, the RO resource information includes RO configuration information, and if there is no individual random access occasion (RO) resource information configured in the configuration information of the CFRA for the terminal, the step of determining RO resource information of the initiated two-step CFRA based on RO resource information of the designated release contention random access (CBRA) includes the following step S201:

[0050] In step S201, if there is no individual RO configuration information set in the configuration information of the CFRA for the terminal, the RO configuration information in the RO resource information of the 4-step CBRA of the specified release is determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0051] In one embodiment, since the RO resource information includes RO configuration information, the absence of individual RO resource information set in the configuration information of the CFRA for the terminal at least includes the absence of RO configuration information in the individual RO resource information set in the configuration information of the CFRA for the terminal.

[0052] In this case, the terminal can determine the RO configuration information in the RO resource information of the 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0053] 3 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 3, the step of determining the RO configuration information in the RO resource information of the four-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S301:

[0054] In step S301, the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release is determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0055] In one embodiment, the specified release may be a legacy release, in which case the terminal may determine the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0056] 4 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 4, the step of determining the RO configuration information in the RO resource information of the four-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S401:

[0057] In step 401, the RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 is determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0058] In one embodiment, the specified release may be Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple 4-step CBRA RO resource information of Release 17.

[0059] In this case, the terminal may determine the RO configuration information in some (which may be one or more) of the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA, or may determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0060] Here, the terminal determines RO configuration information in some resource information among multiple RO resource information of Rel. 17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA, and the some resource information may be determined based on a pre-defined R17 4-step CBRA configuration information list, for example, multiple RO configuration information are arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0061] In addition, when the terminal determines the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA, it means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0062] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the plurality of Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: When an instruction of a network side device to determine RO resource information of an initiated 2-step CFRA based on RO resource information of a Release-17 4-step CBRA is received, determining RO configuration information in part or all of the resource information of the RO resource information of the Release-17 4-step CBRA as RO configuration information in the RO resource information of the initiated 2-step CFRA; The method comprises: If an instruction from the network side device to determine RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of Release 17 has not been received, the method further includes a step of determining RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0063] In an embodiment, the terminal may determine, based on an instruction from the network side device, whether to determine RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0064] For example, when an instruction from the network side device to determine RO resource information of an initiated 2-step CFRA based on RO resource information of a Release-17 4-step CBRA is received, the terminal may determine RO configuration information in some or all of the RO resource information of multiple Release-17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0065] If an instruction from the network side device to determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of Release 17 has not been received, the RO configuration information in the RO resource information of the initiated 2-step CFRA may be determined based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0066] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the plurality of Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: When the terminal supports determining RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the Release-17 4-step CBRA, determining RO configuration information in part or all of the resource information of the RO resource information of the Release-17 4-step CBRA as RO configuration information in the RO resource information of the initiated 2-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated 2-step CFRA based on RO resource information of the 4-step CBRA of Release 17, the method further includes determining RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0067] In an embodiment, the terminal may determine, based on its own capabilities, whether to determine RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0068] For example, if a UE has the capability of supporting determining RO resource information of an initiated two-step CFRA based on RO resource information of a Release-17 four-step CBRA, it can determine the RO configuration information in some or all of the RO resource information of multiple Release-17 four-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0069] If the terminal capability does not support determining the RO resource information of an initiated 2-step CFRA based on the RO resource information of a 4-step CBRA of Release 17, it may determine the RO configuration information in the RO resource information of an initiated 2-step CFRA based on the RO configuration information in the RO resource information of a 4-step CBRA of a legacy release.

[0070] In one embodiment, the terminal capability may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. The terminal may determine features supported by its capability in the features, and the terminal may determine RO resource information of one or more 4-step CBRAs corresponding to the supported features in RO resource information of multiple 4-step CBRAs of Release 17, and may further determine RO configuration information in the RO resource information of the initiated 2-step CFRA in the determined RO resource information of the one or more 4-step CBRAs.

[0071] For example, if a network side device configures RO resource information of four 4-step CBRAs in Release 17 for a terminal for four types of features, i.e., Slicing, SDT, CE, and Redcap, and the terminal is capable of supporting only two features, i.e., CE and Redcap, the terminal can determine RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features in the RO resource information of four 4-step CBRAs in Release 17, and further determine RO configuration information in the RO resource information of the initiated 2-step CFRA from the determined RO resource information of the two 4-step CBRAs.

[0072] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: The method includes a step of determining, based on an implementation of the terminal, RO configuration information in the RO resource information of some or all of the plurality of Release 17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0073] For example, if the terminal determines based on its own implementation that the RO configuration information in the RO resource information of some or all of the RO resource information of the 4-step CBRA of Release 17 is not determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA, the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release may be determined based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release; For example, based on its own implementation, the terminal may determine RO configuration information in some of the RO resource information of a plurality of 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0074] For example, based on its own implementation, the terminal may determine the RO configuration information in all of the RO resource information of the Release-17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0075] In addition, regarding the implementation of the terminal, it is possible to combine embodiments such as instructions from the network side device described above. For example, the network side device instructs the terminal to determine the RO configuration information in the RO resource information of some or all of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA. Based on its own implementation, the terminal can select the RO configuration information in one or more of the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0076] 5 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 5, the step of determining the RO configuration information in the RO resource information of the four-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S501:

[0077] In step S501, the RO configuration information in some or all of the resource information of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 is determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0078] In one embodiment, the specified release may include a legacy release and Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple 4-step CBRA RO resource information for Release 17.

[0079] In this case, the terminal may determine the RO configuration information in some (which may be one or more) of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA, or may determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0080] Here, when the terminal determines the RO configuration information of some of the RO resource information of at least a plurality of Rel. 17 4-step CBRAs as the RO configuration information of the initiated 2-step CFRA, the some resource information may be determined based on a predefined R17 4-step CBRA configuration information list, for example, a plurality of RO configuration information are arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0081] In addition, when the terminal determines the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA, it means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0082] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the plurality of 4-step CBRA of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: When an instruction from the network side device to determine RO resource information of the initiated 2-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17 is received, determining RO configuration information in part or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA; The method comprises: If an instruction from the network side device to determine RO resource information of the initiated 2-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17 is not received, the method further includes a step of determining RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release.

[0083] In one embodiment, the terminal can determine, based on an instruction from the network side device, whether to determine RO configuration information in some or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0084] For example, when an instruction is received from a network side device to determine RO resource information of an initiated 2-step CFRA based on RO resource information of a 4-step CBRA of a legacy release and RO resource information of a 4-step CBRA of Release 17, the RO configuration information in some or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 can be determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0085] If an instruction from the network side device to determine the RO resource information of the initiated 2-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17 has not been received, the RO configuration information in the RO resource information of the initiated 2-step CFRA can be determined based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0086] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the plurality of 4-step CBRA of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: If the terminal supports determining RO resource information of an initiated 2-step CFRA based on RO resource information of a 4-step CBRA of Release 17, determining RO configuration information in part or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated 2-step CFRA based on RO resource information of the 4-step CBRA of Release 17, the method further includes determining RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0087] In one embodiment, the terminal can determine, based on its own capabilities, whether to determine RO configuration information in some or all of the resource information of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0088] For example, if a UE has the capability to support determining RO resource information of an initiated 2-step CFRA based on RO resource information of a 4-step CBRA of Release 17, it can determine the RO configuration information in some or all of the RO resource information of the 4-step CBRA of a legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0089] If its capability does not support determining the RO resource information of an initiated 4-step CFRA based on the RO resource information of a Release-17 4-step CBRA, it may determine the RO configuration information in the RO resource information of an initiated 2-step CFRA based only on the RO configuration information in the RO resource information of a legacy release 4-step CBRA.

[0090] In one embodiment, the terminal capabilities may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. The terminal may determine features supported by its capabilities in the features, and when the terminal determines the RO resource information of the initiated two-step CFRA based on at least the RO resource information of the Release-17 four-step CFRA, the terminal may determine the RO resource information of one or more four-step CBRAs corresponding to the supported features in the RO resource information of the multiple Release-17 four-step CBRAs, and may further determine RO configuration information in the RO resource information of the initiated two-step CFRA in the determined RO resource information of the one or more four-step CBRAs.

[0091] For example, if a network side device configures RO resource information of four 4-step CBRAs in Release 17 for a terminal for four types of features, i.e., Slicing, SDT, CE, and Redcap, and the terminal is capable of supporting only two features, i.e., CE and Redcap, the terminal can determine RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features in the RO resource information of four 4-step CBRAs in Release 17, and further determine RO configuration information in the RO resource information of the initiated 2-step CFRA from the determined RO resource information of the two 4-step CBRAs.

[0092] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: The method includes a step of determining, based on the implementation of the terminal, RO configuration information in some or all of the resource information of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0093] For example, the terminal's own implementation may determine the RO configuration information in some or all of the resource information of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0094] For example, the terminal's own implementation may only need to determine the RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0095] For example, the terminal's own implementation may be to determine RO configuration information in the RO resource information of the initiated 2-step CFRA based only on the RO resource information of the 4-step CBRA of the legacy release.

[0096] Hereinafter, some embodiments will be described by way of example how to determine the RO resource information of an initiated two-step CFRA when the entire RO resource information is the default.

[0097] 6 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 6, the RO resource information includes RO configuration information and the corresponding relationship, and when there is no individual random access occasion (RO) resource information configured in the configuration information of the CFRA for the terminal, the step of determining RO resource information of the initiated two-step CFRA based on the RO resource information of the designated release of contention random access (CBRA) includes the following step S601:

[0098] In step S601, if there is no correspondence between an individual RO configuration set in the CFRA configuration information for the terminal and the RO resource information of the two-step contention random access (CBRA) of the specified release, the RO configuration information in the RO resource information of the initiated two-step CFRA is determined as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0099] In one embodiment, when the RO resource information includes RO configuration information and the correspondence relationship, i.e., when there is no individual RO configuration and the correspondence relationship set in the configuration information of the CFRA for the terminal, the terminal can determine the RO configuration information in the RO resource information of the two-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0100] 7 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 7, the step of determining the RO configuration information in the RO resource information of the two-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S701:

[0101] In step S701, the RO configuration information in the RO resource information of the 2-step CBRA of the legacy release is determined as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0102] In one embodiment, the specified release may be a legacy release, in which case the terminal may determine the RO configuration information in the RO resource information of the two-step CBRA of the legacy release as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0103] 8 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 8, the step of determining the RO configuration information in the RO resource information of the two-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S801:

[0104] In step S801, the RO configuration information in some or all of the RO resource information of a plurality of Release-17 two-step CBRAs is determined as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0105] In one embodiment, the specified release may be Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple two-step CBRA RO resource information of Release 17.

[0106] In this case, the terminal may determine the RO configuration information in some (which may be one or more) of the RO resource information of multiple two-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA, or may determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0107] Here, the terminal determines RO configuration information in some resource information among multiple RO resource information of Rel. 17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA, and the some resource information can be determined based on a predefined R17 two-step CBRA configuration information list, for example, multiple RO configuration information are arranged in order in the list, and the some resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0108] In addition, when the terminal determines the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA, it means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0109] In one embodiment, the step of determining RO configuration information in some or all of the RO resource information of the plurality of Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA includes: When an instruction of a network side device to determine RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 two-step CFRA is received, determining RO configuration information in part or all of the resource information of the RO resource information of a plurality of Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA; The method comprises: If an instruction from the network side device to determine RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the two-step CFRA of Release 17 is not received, the method further includes a step of determining RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0110] In an embodiment, the terminal may determine, based on an instruction from the network side device, whether to determine RO configuration information in some or all of the RO resource information of multiple two-step CBRAs in Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0111] For example, when an instruction from the network side device to determine the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 two-step CBRA is received, the terminal may determine the RO configuration information in some or all of the resource information of the multiple Release-17 two-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0112] If an instruction from the network side device to determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of Release 17 has not been received, the RO configuration information in the RO resource information of the initiated two-step CFRA may be determined based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0113] In one embodiment, the step of determining RO configuration information in some or all of the RO resource information of the plurality of Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA includes: When the terminal supports determining RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the Release-17 two-step CFRA, determining RO configuration information in some or all of the resource information of the RO resource information of the Release-17 two-step CBRA as RO configuration information in the RO resource information of the initiated two-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated two-step CFRA based on RO resource information of the two-step CFRA of Release 17, the method further includes determining RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the two-step CBRA of a legacy release.

[0114] In an embodiment, the terminal may determine, based on its own capabilities, whether to determine RO configuration information in some or all of the RO resource information of multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0115] For example, if a UE has the capability of supporting determining the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 two-step CBRA, it can determine the RO configuration information in some or all of the RO resource information of multiple Release-17 two-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0116] If the terminal capability does not support determining the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release 17 two-step CBRA, it can determine the RO configuration information in the RO resource information of an initiated two-step CFRA based on the RO configuration information in the RO resource information of a legacy release two-step CBRA.

[0117] In one embodiment, the terminal capability may further include a terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. The terminal may determine features supported by its capability in the features, and the terminal may determine one or more two-step CBRA RO resource information corresponding to the supported features in the RO resource information of multiple two-step CBRAs of Release 17, and may further determine the determined one or more two-step CBRA RO resource information as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0118] For example, a network side device configures the RO resource information of four two-step CBRAs in Release 17 for a terminal for four types of features, namely Slicing, SDT, CE, and Redcap. If the terminal's capability supports only two of the features, namely CE and Redcap, the terminal can determine the RO resource information of two two-step CBRAs corresponding to the CE and Redcap features in the RO resource information of four two-step CBRAs in Release 17, and further determine the RO configuration information in the RO resource information of the initiated two-step CFRA from the determined RO resource information of the two two-step CBRAs.

[0119] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA includes: The method includes a step of determining, based on an implementation of the terminal, RO configuration information in the RO resource information of some or all of the Release-17 two-step CBRAs of multiple Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0120] For example, if the terminal determines based on its own implementation that the RO configuration information in the RO resource information of some or all of the RO resource information of the two-step CBRAs of Release 17 is not to be determined as the RO configuration information in the RO resource information of the initiated two-step CFRA, the terminal may determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release; For example, based on its own implementation, the terminal may determine RO configuration information in some of the RO resource information of a plurality of Release 17 2-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0121] For example, the terminal may determine, based on its own implementation, the RO configuration information in the RO resource information of all of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0122] In addition, regarding the implementation of the terminal, it is possible to combine embodiments such as instructions from the network side device described above. For example, the network side device instructs the terminal to determine the RO configuration information in the RO resource information of some or all of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA. Based on its own implementation, the terminal can select the RO configuration information in one or more of the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0123] 9 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 9, the step of determining the RO configuration information in the RO resource information of the two-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S901:

[0124] In step S901, the RO configuration information in some or all of the resource information of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 is determined as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0125] In one embodiment, the specified release may include a legacy release and Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple two-step CBRA RO resource information for Release 17.

[0126] In this case, the terminal may determine the RO configuration information in some (which may be one or more) of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA, or may determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0127] Here, when the terminal determines the RO configuration information of some of the RO resource information of at least a plurality of Rel. 17 two-step CBRAs as the RO configuration information of the initiated two-step CFRA, the some resource information may be determined based on a predefined R17 two-step CBRA configuration information list, for example, a plurality of RO configuration information are arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0128] In addition, when the terminal determines the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA, it means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0129] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the plurality of two-step CBRA of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA includes: When an instruction from the network side device to determine RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the two-step CBRA of Release 17 is received, determining RO configuration information in part or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA; The method comprises: If an instruction from the network side device to determine RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the two-step CBRA of Release 17 is not received, the method further includes a step of determining RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of the legacy release.

[0130] In one embodiment, the terminal can determine, based on an instruction from the network side device, whether to determine RO configuration information in some or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 2-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0131] For example, when an instruction is received from a network side device to determine RO resource information of an initiated two-step CFRA based on RO resource information of a two-step CBRA of a legacy release and RO resource information of a two-step CBRA of Release 17, the RO configuration information in some or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 can be determined as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0132] If an instruction from the network side device to determine the RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the two-step CBRA of Release 17 has not been received, the RO configuration information in the RO resource information of the initiated two-step CFRA can be determined based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0133] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the plurality of two-step CBRA of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA includes: If the terminal supports determining RO resource information of an initiated two-step CFRA based on RO resource information of a two-step CBRA of Release 17, determining RO configuration information in part or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated two-step CFRA based on RO resource information of the two-step CFRA of Release 17, the method further includes determining RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the two-step CBRA of a legacy release.

[0134] In one embodiment, the terminal can determine, based on its own capabilities, whether to determine RO configuration information in some or all of the resource information of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0135] For example, if a UE has the capability to support determining the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release 17 two-step CBRA, it can determine the RO configuration information in some or all of the resource information of the RO resource information of the legacy release two-step CBRA and the RO resource information of multiple Release 17 two-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0136] If its capability does not support determining the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 two-step CBRA, it may determine the RO configuration information in the RO resource information of an initiated two-step CFRA based only on the RO configuration information in the RO resource information of a legacy release two-step CBRA.

[0137] In one embodiment, the terminal capability may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. The terminal may determine features supported by its capability in the features, and when the terminal determines the RO resource information of the initiated two-step CFRA based on at least the RO resource information of the Release-17 two-step CFRA, the terminal may determine the RO resource information of one or more two-step CBRAs corresponding to the supported features in the RO resource information of the Release-17 multiple two-step CBRAs, and may further determine the RO configuration information in the RO resource information of the initiated two-step CFRA in the determined RO resource information of the one or more two-step CBRAs.

[0138] For example, a network side device configures the RO resource information of four two-step CBRAs in Release 17 for a terminal for four types of features, namely Slicing, SDT, CE, and Redcap. If the terminal's capability supports only two features, namely CE and Redcap, the terminal can determine the RO resource information of two two-step CBRAs corresponding to the CE and Redcap features in the RO resource information of four two-step CBRAs in Release 17, and further determine the RO configuration information in the RO resource information of the initiated two-step CFRA from the determined RO resource information of the two two-step CBRAs.

[0139] In one embodiment, the step of determining RO configuration information in part or all of the RO resource information of the Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA includes: The method includes a step of determining, based on the implementation of the terminal, RO configuration information in some or all of the resource information of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0140] For example, the terminal's own implementation may determine the RO configuration information in some or all of the resource information of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0141] For example, the terminal's own implementation may only need to determine the RO configuration information in some or all of the RO resource information of multiple two-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0142] For example, the terminal's own implementation may be to determine RO configuration information in the RO resource information of the initiated 2-step CFRA based only on the RO resource information of the 2-step CBRA of the legacy release.

[0143] 10 is a schematic flowchart of another method for determining random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 10, if there is no individual random access occasion (RO) resource information configured in the CFRA configuration information for the terminal, the step of determining RO resource information of the initiated two-step CFRA based on RO resource information of the designated release contention random access (CBRA) further includes the following step S1001:

[0144] In step S1001, determine the correspondence between the SSB and the RO in the RO resource information of the initiated two-step CFRA.

[0145] In an embodiment, since the RO resource information of the two-step CFRA includes two parts, namely, RO configuration information and a correspondence relationship between an SSB and an RO, in addition to needing to determine the RO configuration information in the RO resource information of the two-step CFRA, it is also needed to determine the correspondence relationship between an SSB and an RO in the RO resource information of the two-step CFRA, and the terminal can determine the RO on which the two-step CFRA is performed according to the determined RO configuration information and the correspondence relationship between an SSB and an RO.

[0146] In one embodiment, the step of determining a correspondence relationship between an SSB and an RO in RO resource information of the initiated two-step CFRA includes: The method includes determining a correspondence relationship between a synchronization signal block (SSB) and an RO in RO resource information of the two-step CBRA of the specified release as a correspondence relationship between an SSB and an RO in RO resource information of the initiated two-step CFRA.

[0147] After the UE determines the RO configuration information in the RO resource information of the CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA according to the above embodiment, the UE can further determine the correspondence relationship between a synchronization signal block (SSB) and an RO in the RO resource information of the CBRA of the designated release as the correspondence relationship between an SSB and an RO in the RO resource information of the initiated two-step CFRA, that is, the RO configuration information and the correspondence relationship between an SSB and an RO can belong to the same RO resource information.

[0148] In one embodiment, the step of determining a correspondence relationship between an SSB and an RO in RO resource information of the initiated two-step CFRA includes: The method includes determining a correspondence relationship between a synchronization signal block (SSB) and an RO in RO resource information of an initiated two-step CFRA based on a correspondence relationship between an SSB and an RO in RO resource information of a two-step CBRA of all releases preset in the terminal by a network side device.

[0149] After the terminal determines the RO configuration information in the RO resource information of the CBRA of the specified release as the RO configuration information of the RO resource information of the initiated two-step CFRA based on the above embodiment, the terminal can determine the correspondence relationship between the synchronization signal block (SSB) and the RO in the RO resource information of the initiated two-step CFRA based on the correspondence relationship between the SSB and the RO in the RO resource information of the CBRA of all releases (which does not need to be limited to the RO resource information of the CBRA of the specified release) pre-configured in the terminal by the network side device.

[0150] In addition, if there are multiple correspondence relationships between SSBs and ROs in the RO resource information of CBRA for all releases pre-configured in the terminal by the network side device, the terminal can determine one correspondence relationship between the SSBs and ROs from among them, and the correspondence relationships between the SSBs and ROs are expressed by values ​​such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, and 16, and the terminal can select one of the values, for example, the maximum or minimum value.

[0151] In one embodiment, the step of determining a correspondence relationship between an SSB and an RO in RO resource information of the initiated two-step CFRA includes: The method includes determining, based on an implementation of the terminal, a correspondence relationship between an SSB and an RO in the RO resource information of the initiated two-step CFRA.

[0152] The following embodiment describes how the terminal determines the RO resource information of the initiated two-step CFRA when instructed by the network side device from the network side. It should be noted that the instruction of the network side device is only one of the ways that the terminal determines the RO resource information of the initiated two-step CFRA according to the random access occasion (RO) resource information of the CBRA of the specified release, and the terminal can also determine the RO resource information of the initiated two-step CFRA according to the protocol according to the random access occasion (RO) resource information of the CBRA of the specified release.

[0153] 11 is a schematic flowchart of a method for indicating random access occasion resource information according to an embodiment of the present disclosure. The method for indicating random access occasion resource information according to this embodiment can be performed by a network side device, the network side device can communicate with a terminal, the terminal includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices, and the network side device includes but is not limited to network side devices in communication systems such as 4G, 5G, 6G, such as base stations and core networks.

[0154] As shown in FIG. 11, the method for indicating random access occasion resource information may include the following steps S1101 to S1102.

[0155] In step S1101, the terminal initiates two-step non-contention random access (CFRA).

[0156] In step S1102, if there is no individual random access occasion (RO) resource information set in the CFRA configuration information for the terminal, instruct the terminal to determine RO resource information of the initiated two-step CFRA based on RO resource information of contention random access (CBRA) of a specified release.

[0157] In one embodiment, in some cases, the network side device may initiate the terminal to perform two-step CFRA, and the manner of initiating the two-step CFRA includes initiating by switching a Handover command.

[0158] After the network side device initiates the terminal to perform two-step CFRA, the terminal needs to determine RO resource information for the two-step CFRA, for example, by determining whether there is RO resource information individually configured for the terminal in the CFRA configuration information. If there is RO resource information individually configured for the terminal, the terminal can determine an RO to initiate two-step CFRA based on the RO resource information individually configured for the terminal; if there is no RO resource information individually configured for the terminal, the terminal can determine the RO resource information for the initiated two-step CFRA based on the RO resource information of the CBRA.

[0159] According to an embodiment of the present disclosure, a network side device can instruct a terminal to determine RO resource information of an initiated two-step CFRA based on RO resource information of a CBRA of a specified release. Even if RO resource information of a legacy release and RO resource information of a CBRA of Release 17 are configured for a terminal, the terminal can accurately determine based on which RO resource information of a CBRA of a release to determine RO resource information of an initiated two-step CFRA. This avoids a technical problem that, when a terminal faces RO resource information of CBRA of multiple releases, it is difficult to determine based on which RO resource information of a CBRA of a release to determine RO resource information of a two-step CFRA.

[0160] In one embodiment, when there is no individual random access occasion (RO) resource information configured in the CFRA configuration information for the terminal, the step of instructing the terminal to determine RO resource information of the initiated two-step CFRA based on RO resource information of a contention random access (CBRA) of a specified release includes: When there is no individual RO resource information set in the configuration information of the CFRA for the terminal, and when RO resource information of multiple CBRAs has already been configured for the terminal, the step of instructing to set the RO resource information of the target CBRA among the RO resource information of the multiple CBRAs as the RO resource information of the initiated two-step CFRA is included.

[0161] When a network side device configures RO resource information of multiple CBRAs for a terminal, the network side device can instruct the terminal to determine RO resource information of an initiated two-step CFRA based on RO resource information of a contention random access (CBRA) of a specified release, and can also more accurately instruct the terminal to set the RO resource information of a target CBRA in the RO resource information of the multiple CBRAs as the RO resource information of the initiated two-step CFRA.

[0162] In one embodiment, the specified release includes at least one of a legacy release and Release 17. In one embodiment, the legacy release includes at least one of Release 15 and Release 16.

[0163] In one embodiment, the RO resource information includes: RO setting information, and a correspondence between a synchronization signal block (SSB) and an RO.

[0164] In one embodiment, the RO resource information may include two parts of content: RO configuration information and a correspondence relationship between an SSB and an RO, and the terminal determining the RO resource information of the initiated two-step CFRA based on the RO resource information of the designated release contention random access (CBRA) includes two corresponding cases: one is determining the RO configuration information in the RO resource information of the initiated two-step CFRA, and the other is determining the correspondence relationship between the SSB and the RO in the RO resource information of the two-step CFRA.

[0165] Accordingly, the absence of individual random access occasion (RO) resource information configured in the CFRA configuration information for the terminal also includes two cases: one is that only the RO configuration information in the RO resource information is default, and the other is that the entire RO resource information is default.

[0166] When only the RO configuration information in the RO resource information is default, it is necessary to instruct the terminal to determine the RO configuration information in the RO resource information of the initiated two-step CFRA, for example, the RO configuration information in the RO resource information of the initiated two-step CFRA can be determined according to the RO configuration information in the RO resource information of the two-step CBRA; If the entire RO resource information is default, it is necessary to instruct the terminal to determine the RO configuration information in the RO resource information of the initiated two-step CFRA and the corresponding relationship between the SSB and the RO, for example, the RO configuration information in the RO resource information of the initiated two-step CFRA can be determined based on the RO configuration information in the RO resource information of the four-step CBRA. Instructing the terminal to determine the corresponding relationship between the SSB and the RO will be described in the subsequent embodiment.

[0167] In the following, firstly, some embodiments will be illustratively described of how to instruct a terminal to determine RO configuration information in RO resource information of an initiated 2-step CFRA based on RO configuration information in RO resource information of a 4-step CBRA.

[0168] 12 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 12, the RO resource information includes RO configuration information, and if there is no individual random access occasion (RO) resource information configured in the configuration information of the CFRA for the terminal, the step of determining RO resource information of the initiated two-step CFRA based on RO resource information of the designated release of contention random access (CBRA) includes the following step S1201:

[0169] In step S1201, if there is no individual RO configuration information set in the configuration information of the CFRA for the terminal, the terminal is instructed to determine the RO configuration information in the RO resource information of the 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0170] In one embodiment, since the RO resource information includes RO configuration information, the absence of individual RO resource information set in the configuration information of the CFRA for the terminal at least includes the absence of RO configuration information in the individual RO resource information set in the configuration information of the CFRA for the terminal.

[0171] In this case, the network side device may instruct the terminal to determine the RO configuration information in the RO resource information of the 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0172] 13 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 13, the step of instructing the terminal to determine the RO configuration information in the RO resource information of the four-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S1301:

[0173] In step S1301, the terminal is instructed to determine the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0174] In one embodiment, the specified release may be a legacy release, in which 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 release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0175] 14 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 14, the step of instructing the terminal to determine the RO configuration information in the RO resource information of the four-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S1401:

[0176] In step 1401, the terminal is instructed to determine RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0177] In one embodiment, the specified release may be Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple 4-step CBRA RO resource information of Release 17.

[0178] In this case, the network side device may instruct the terminal to determine the RO configuration information in a portion (which may be one or more) of the RO resource information of the multiple 4-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA, or may instruct the terminal to determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0179] Here, the network side device instructs the terminal to determine RO configuration information in some resource information among the RO resource information of multiple Rel. 17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA, where the some resource information can be determined based on a predefined R17 4-step CBRA configuration information list, for example, by arranging multiple RO configuration information in the list in order, and the some resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0180] In addition, when the network side device instructs the terminal to determine the RO configuration information in the entire resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA, it means that all ROs configured by the RO configuration information in the entire resource information are available to the terminal.

[0181] In one embodiment, the step of instructing the terminal to determine RO configuration information in some or all of the RO resource information of a plurality of Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: The method includes a step of instructing the terminal to determine RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0182] In one embodiment, when the network side device can instruct the terminal to determine the RO resource information of the initiated two-step CFRA based on the RO resource information of the Rel.-17 four-step CBRA, after receiving the instruction, the terminal can determine the RO configuration information in some or all of the RO resource information of the multiple Rel.-17 four-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0183] If the network side device does not instruct the terminal to determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of Release 17, the terminal may determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0184] In one embodiment, the step of instructing the terminal to determine RO configuration information in some or all of the RO resource information of a plurality of Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: If the terminal supports determining RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the Release-17 4-step CBRA, instructing the terminal to determine RO configuration information in part or all of the resource information of the RO resource information of the Release-17 4-step CBRA as RO configuration information in the RO resource information of the initiated 2-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated 2-step CFRA based on RO resource information of the 4-step CBRA of Release 17, the method further includes instructing the terminal to determine RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0185] In an embodiment, the network side device may determine, based on the capability of the terminal, whether the terminal supports determining RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0186] For example, if it is determined that the terminal supports determining the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 four-step CBRA, the terminal may be instructed to determine the RO configuration information in some or all of the RO resource information of multiple Release-17 four-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0187] If it is determined that the terminal does not support determining the RO resource information of the initiated 2-step CFRA based on the RO resource information of the 4-step CBRA of Release 17, the terminal may be instructed to determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0188] In one embodiment, the terminal capability may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. Since the network side device can determine the features supported by the terminal in the features based on the terminal capability, the network side device can determine RO resource information of one or more 4-step CBRAs corresponding to the supported features in the RO resource information of multiple 4-step CBRAs of Release 17, and further instruct the terminal to determine RO configuration information in the RO resource information of the initiated 2-step CFRA in the determined RO resource information of the one or more 4-step CBRAs.

[0189] For example, the network side device configures the RO resource information of four 4-step CBRAs of Release 17 for the terminal for four types of features, namely Slicing, SDT, CE, and Redcap, respectively, and determines based on the terminal's capabilities that the terminal supports only two of the features, namely CE and Redcap. Then, the network side device can instruct the terminal to determine the RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features in the RO resource information of the four 4-step CBRAs of Release 17, and further determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the determined RO resource information of the two 4-step CBRAs.

[0190] 15 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 15, the step of instructing the terminal to determine the RO configuration information in the RO resource information of the four-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S1501:

[0191] In step S1501, the terminal is instructed to determine the RO configuration information in some or all of the resource information of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0192] In one embodiment, the specified release may include a legacy release and Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple 4-step CBRA RO resource information for Release 17.

[0193] In this case, the network side device may instruct the terminal to determine the RO configuration information in some (which may be one or more) of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA, or may instruct the terminal to determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0194] Here, when instructing the terminal to determine RO configuration information in at least some of the RO resource information of multiple Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 2-step CFRA, the some resource information can be determined based on a predefined R17 4-step CBRA configuration information list, for example, multiple RO configuration information are arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0195] In addition, instructing the terminal to determine the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0196] In one embodiment, when the network side device can instruct the terminal to determine RO resource information of the initiated two-step CFRA based on the RO resource information of the four-step CBRA of the legacy release and the RO resource information of the four-step CBRA of Release 17, the terminal can determine, based on the instruction, the RO configuration information in some or all of the RO resource information of the four-step CBRA of the legacy release and the RO resource information of multiple four-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0197] If the network side device does not instruct the terminal to determine the RO resource information of the initiated 2-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17, the terminal can determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0198] In one embodiment, the step of instructing the terminal to determine RO configuration information in part or all of resource information of RO resource information of a 4-step CBRA of a legacy release and RO resource information of a plurality of 4-step CBRAs of Release 17 as RO configuration information in RO resource information of an initiated 2-step CFRA includes: If the terminal supports determining RO resource information of an initiated 2-step CFRA based on RO resource information of a 4-step CBRA of Release 17, instructing the terminal to determine RO configuration information in part or all of the RO resource information of the 4-step CBRA of a legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated 2-step CFRA based on RO resource information of the 4-step CBRA of Release 17, the method further includes instructing the terminal to determine RO configuration information in the RO resource information of the initiated 2-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0199] In one embodiment, the network side device may determine, based on the capability of the terminal, whether the terminal supports determining RO configuration information in some or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0200] For example, if it is determined based on the capabilities of the terminal that the terminal supports determining RO resource information of an initiated two-step CFRA based on RO resource information of a four-step CBRA of Release 17, the terminal may be instructed to determine RO configuration information in some or all of the resource information of the four-step CBRA of the legacy release and the RO resource information of multiple four-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0201] If it is determined based on the terminal capabilities that the terminal does not support determining the RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA of Release 17, the terminal may be instructed to determine the RO configuration information in the RO resource information of the initiated 2-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0202] In one embodiment, the terminal capability may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. The network side device may determine the features supported by the terminal in the features based on the terminal capability, and when the terminal determines the RO resource information of the initiated two-step CFRA based on at least the RO resource information of the Release-17 four-step CFRA, the network side device may determine the RO resource information of one or more four-step CBRAs corresponding to the features supported by the terminal in the RO resource information of the multiple Release-17 four-step CBRAs, and further instruct the terminal to determine RO configuration information in the RO resource information of the initiated two-step CFRA in the determined RO resource information of the one or more four-step CBRAs.

[0203] For example, the network side device configures the RO resource information of four 4-step CBRAs in Release 17 for the terminal for four types of features, namely Slicing, SDT, CE, and Redcap, respectively, and determines that the terminal supports only two of the features, namely CE and Redcap, based on the terminal's capabilities. Then, the network side device can determine the RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features in the RO resource information of the four 4-step CBRAs in Release 17, and further instruct the terminal to determine the determined RO resource information of the two 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0204] 16 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 16, the RO resource information includes RO configuration information and the correspondence relationship, and when there is no individual random access occasion (RO) resource information configured in the configuration information of the CFRA for the terminal, the step of instructing the terminal to determine RO resource information of the initiated two-step CFRA based on RO resource information of the designated release of contention random access (CBRA) includes the following steps:

[0205] In step S1601, if there is no correspondence between an individual RO configuration set in the configuration information of the CFRA for the terminal and the RO configuration information, the terminal is instructed to determine the RO configuration information in the RO resource information of the two-step contention random access (CBRA) of the specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0206] In one embodiment, when the RO resource information includes RO configuration information and the correspondence relationship, i.e., when there is no individual RO configuration set in the configuration information of the CFRA for the terminal and the correspondence relationship, the network side device instructs the terminal to determine the RO configuration information in the RO resource information of the two-step CBRA of a specified release as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0207] 17 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 17, the step of instructing the terminal to determine the RO configuration information in the RO resource information of the two-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S1701:

[0208] In step S1701, the terminal is instructed to determine the RO configuration information in the RO resource information of the 2-step CBRA of the legacy release as the RO configuration information in the RO resource information of the initiated 2-step CFRA.

[0209] In one embodiment, the specified release may be a legacy release, in which case the network side device can instruct the terminal to determine the RO configuration information in the RO resource information of the two-step CBRA of the legacy release as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0210] 18 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 18, the step of instructing the terminal to determine the RO configuration information in the RO resource information of the two-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S1801:

[0211] In step S1801, the terminal is instructed to determine RO configuration information in some or all of the resource information of the RO resource information of multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0212] In one embodiment, the specified release may be Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple two-step CBRA RO resource information of Release 17.

[0213] In this case, the network side device may instruct the terminal to determine the RO configuration information in a portion (which may be one or multiple) of the RO resource information of multiple two-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA, or may instruct the terminal to determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0214] Here, the terminal is instructed to determine RO configuration information in some resource information among multiple RO resource information of Release 17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA, and the some resource information can be determined based on a pre-defined R17 two-step CBRA configuration information list, for example, multiple RO configuration information are arranged in order in the list, and the some resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0215] In addition, instructing the terminal to determine the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0216] In one embodiment, when the network side device can instruct the terminal to determine RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 two-step CBRA, the terminal can determine, based on the instruction, RO configuration information in some or all of the RO resource information of multiple Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0217] If the network side device does not instruct the terminal to determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of Release 17, the terminal may determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0218] In one embodiment, the step of instructing the terminal to determine RO configuration information in some or all of the RO resource information of a plurality of Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA includes: If the terminal supports determining RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the Release-17 two-step CFRA, instructing the terminal to determine RO configuration information in part or all of the resource information of the RO resource information of a plurality of Release-17 two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated two-step CFRA based on RO resource information of the two-step CFRA of Release 17, the method includes a step of instructing the terminal to determine RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the two-step CBRA of a legacy release.

[0219] In an embodiment, the network side device may determine, based on the capability of the terminal, whether the terminal supports determining RO configuration information in some or all of the RO resource information of multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0220] For example, if it is determined based on the capabilities of the terminal that the terminal supports determining the RO resource information of an initiated two-step CFRA based on the RO resource information of a Release-17 two-step CBRA, the terminal may determine the RO configuration information in some or all of the resource information of the RO resource information of multiple Release-17 two-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0221] If it is determined based on the terminal capabilities that the terminal does not support determining the RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of Release 17, the terminal may be instructed to determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0222] In one embodiment, the terminal capability may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. Since the network side device can determine the features supported by the terminal in the features based on the terminal capability, the network side device can determine one or more two-step CBRA RO resource information corresponding to the features supported by the terminal in the RO resource information of multiple two-step CBRAs of Release 17, and further instruct the terminal to determine RO configuration information in the RO resource information of the initiated two-step CFRA in the determined one or more two-step CBRA RO resource information.

[0223] For example, the network side device configures the RO resource information of four two-step CBRAs in Release 17 for the terminal for four types of features, namely Slicing, SDT, CE, and Redcap. If the network device determines that the terminal supports only two of the features, namely CE and Redcap, the network device can determine the RO resource information of two two-step CBRAs corresponding to the CE and Redcap features in the RO resource information of four two-step CBRAs in Release 17, and further instruct the terminal to determine the determined RO resource information of the two two-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0224] 19 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 19, the step of instructing the terminal to determine the RO configuration information in the RO resource information of the two-step CBRA of the designated release as the RO configuration information in the RO resource information of the initiated two-step CFRA includes the following step S1901:

[0225] In step S1901, the terminal is instructed to determine the RO configuration information in some or all of the resource information of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0226] In one embodiment, the specified release may include a legacy release and Release 17, and since different CBRA configuration information can be configured for different features in Release 17, the terminal can be configured with multiple two-step CBRA RO resource information for Release 17.

[0227] In this case, the network side device may instruct the terminal to determine the RO configuration information in some (which may be one or more) of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the multiple two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA, or may instruct the terminal to determine the RO configuration information in all of the resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0228] When instructing the terminal to determine RO configuration information in some resource information of at least multiple Release-17 two-step CBRA RO resource information as RO configuration information in the initiated two-step CFRA RO resource information, the some resource information may be determined based on a predefined R17 two-step CBRA configuration information list, for example, multiple RO configuration information are arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0229] In addition, instructing the terminal to determine the RO configuration information in all resource information as the RO configuration information in the RO resource information of the initiated two-step CFRA means that all ROs configured by the RO configuration information in the all resource information are available to the terminal.

[0230] In one embodiment, when the network side device can instruct the terminal to determine RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the two-step CBRA of Release 17, the terminal can determine, based on the instruction, the RO configuration information in some or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0231] If the network side device does not instruct the terminal to determine the RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the two-step CBRA of Release 17, the terminal can determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0232] In one embodiment, the step of instructing the terminal to determine RO configuration information in part or all of resource information of RO resource information of a two-step CBRA of a legacy release and RO resource information of a plurality of two-step CBRAs of Release 17 as RO configuration information in RO resource information of an initiated two-step CFRA includes: If the terminal supports determining RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CFRA of Release 17, instructing the terminal to determine RO configuration information in part or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of the multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA; The method comprises: If the terminal does not support determining RO resource information of the initiated two-step CFRA based on RO resource information of the two-step CFRA of Release 17, the method further includes instructing the terminal to determine RO configuration information in the RO resource information of the initiated two-step CFRA based on RO configuration information in the RO resource information of the two-step CBRA of a legacy release.

[0233] In one embodiment, the network side device determines, based on the capability of the terminal, whether the terminal supports determining RO configuration information in some or all of the RO resource information of the two-step CBRA of the legacy release and the RO resource information of multiple two-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA.

[0234] For example, if it is determined that the terminal supports determining the RO resource information of the initiated two-step CFRA based on the RO resource information of the Release 17 two-step CBRA, the terminal may be instructed to determine the RO configuration information in some or all of the resource information of the RO resource information of the legacy release two-step CBRA and the RO resource information of multiple Release 17 two-step CBRAs as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0235] If it is determined that the terminal does not support determining the RO resource information of the initiated two-step CFRA based on the RO resource information of the two-step CBRA of Release 17, the terminal may be instructed to determine the RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO configuration information in the RO resource information of the two-step CBRA of the legacy release.

[0236] In one embodiment, the terminal capability may further include the terminal's support status for features such as Slicing, SDT, CE, Redcap, etc. When the network side device determines the features supported by the terminal based on the terminal capability, and instructs the terminal to determine the RO resource information of the initiated two-step CFRA based on at least the RO resource information of the Release-17 two-step CFRA, the network side device may determine the RO resource information of one or more two-step CBRAs corresponding to the supported features in the RO resource information of the Release-17 multiple two-step CBRAs, and further instruct the terminal to determine the RO configuration information in the RO resource information of the initiated two-step CFRA in the determined RO resource information of the one or more two-step CBRAs.

[0237] For example, the network side device configures the RO resource information of four two-step CBRAs in Release 17 for the terminal for four types of features, namely Slicing, SDT, CE, and Redcap. If the network device determines that the terminal supports only two of the features, namely CE and Redcap, the network device can determine the RO resource information of two two-step CBRAs corresponding to the CE and Redcap features in the RO resource information of four two-step CBRAs in Release 17, and further instruct the terminal to determine the RO configuration information in the RO resource information of the two two-step CFRAs initiated in the determined RO resource information of the two two-step CBRAs.

[0238] 20 is a schematic flowchart of another method for indicating random access occasion resource information according to an embodiment of the present disclosure. As shown in FIG. 20, if there is no individual random access occasion (RO) resource information configured in the configuration information of the CFRA for the terminal, the step of instructing the terminal to determine RO resource information of the initiated two-step CFRA based on RO resource information of the contention random access (CBRA) of the designated release further includes the following step S2001.

[0239] In step S2001, instruct the terminal to determine the corresponding relationship between SSB and RO in RO resource information of the initiated two-step CFRA according to a specified manner.

[0240] In one embodiment, the network side needs to instruct the terminal to determine RO configuration information in the RO resource information of the initiated two-step CFRA according to the RO resource information of the CBRA of the designated release, for example, the RO configuration information in the RO resource information of the CBRA of the designated release can be determined as the RO configuration information of the RO resource information of the initiated two-step CFRA; In order to perform RO of two-step CFRA, the terminal needs to determine the RO configuration information and also needs to determine the correspondence between SSB and RO, so the network side device also needs to instruct the terminal to determine the correspondence between SSB and RO in the RO resource information of the initiated two-step CFRA, and specifically can instruct the terminal to determine the correspondence between SSB and RO in the RO resource information of the initiated two-step CFRA according to a specified manner. Furthermore, the terminal can determine the RO used for the initiated two-step CFRA according to the RO configuration information and the correspondence.

[0241] In one embodiment, the specified method is: Determining a correspondence relationship between a synchronization signal block (SSB) and an RO in the RO resource information of the two-step CBRA of the specified release as a correspondence relationship between an SSB and an RO in the RO resource information of the initiated two-step CFRA; and determining a correspondence relationship between a synchronization signal block (SSB) and an RO in the RO resource information of the initiated two-step CFRA based on a correspondence relationship between an SSB and an RO in the RO resource information of the two-step CBRA of all releases preset in the terminal by a network side device.

[0242] In one embodiment, based on the above embodiment, the network side device instructs the terminal to determine the RO configuration information in the RO resource information of the 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 4-step CFRA, and then can further instruct the terminal to determine the correspondence relationship between a synchronization signal block (SSB) and an RO in the RO resource information of the 4-step CBRA of the specified release as the correspondence relationship between an SSB and an RO in the RO resource information of the initiated 4-step CFRA, that is, the RO configuration information and the correspondence relationship between an SSB and an RO can belong to the same RO resource information.

[0243] In one embodiment, based on the above embodiment, the network side device instructs the terminal to determine the RO configuration information in the RO resource information of the 4-step CBRA of the specified release as the RO configuration information of the RO resource information of the initiated 4-step CFRA, and then instructs the terminal to determine a correspondence relationship between a synchronization signal block (SSB) and an RO in the RO resource information of the initiated 4-step CFRA based on a correspondence relationship between an SSB and an RO in the RO resource information of the 4-step CBRA of all releases pre-configured in the terminal (which does not need to be limited to the RO resource information of the 4-step CBRA of the specified release).

[0244] In addition, if there are multiple correspondence relationships between SSBs and ROs in the RO resource information of the 4-step CBRA of all releases pre-configured in the terminal by the network side device, the terminal can be instructed to determine one of the correspondence relationships between SSBs and ROs from among them, and the correspondence relationships between SSBs and ROs can be expressed as numbers such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16, etc., and the network device can select one of the numbers, for example the maximum or minimum value, and instruct the terminal.

[0245] An embodiment of the present disclosure further proposes a non-contention random access configuration method, which is performed by a network side device, and the method includes: The method includes a step of configuring a two-step contention-free random access (CFRA) resource when a two-step contention-free random access (CBRA) resource of a specified release is configured in a bandwidth portion (BWP) selected by the terminal.

[0246] In one embodiment, the network side device configures the terminal to perform two-step CFRA resource in the BWP selected by the terminal. If the two-step CFRA resource of the terminal is unavailable (e.g., default) for some reason, the terminal needs to perform two-step CFRA using the two-step CBRA resource. However, if the two-step CBRA resource is not configured in the BWP, the terminal cannot perform two-step CFRA using the two-step CBRA resource, which seriously affects the communication effect.

[0247] Therefore, according to the embodiment of the present disclosure, only when the 2-step contention random access (CBRA) resource of the release designated in the bandwidth portion (BWP) selected by the terminal is configured, the 2-step non-contention random access (CFRA) resource is configured, so that even if the 2-step CFRA resource of the terminal is not available, the 2-step CBRA resource can be used to smoothly perform the 2-step CFRA, and the 2-step CFRA can be smoothly performed.

[0248] If a two-step contention random access (CBRA) resource of a specified release is not configured in the bandwidth portion (BWP) selected by the terminal, a two-step non-contention random access (CFRA) resource may not be configured.

[0249] In one embodiment, the designated release is determined based on an instruction from a network side device or is determined based on a protocol.

[0250] In one embodiment, the specified release includes at least one of a legacy release and Release 17. In one embodiment, the legacy release includes at least one of Release 15 and Release 16.

[0251] An embodiment of the present disclosure further proposes a non-contention random access configuration method, which is performed by a network side device, and the method includes: The method includes a step of setting RO configuration information in resource information of the 2-step CFRA when a 4-step contention random access (CBRA) resource of a specified release is not set in a bandwidth portion (BWP) selected by a terminal, or when a 4-step CBRA resource of a specified release is set in the BWP and the 4-step CBRA resource of the specified release is not shared.

[0252] In one embodiment, when the RO configuration information in the resource information of the two-step CFRA is default, the terminal needs to use the RO configuration information in the four-step CBRA resource information, so that if the four-step CBRA resource of the designated release is not configured in the bandwidth part (BWP) selected by the terminal, or if the four-step CBRA resource of the designated release is configured in the BWP and the four-step CBRA resource of the designated release is not shared, the terminal cannot perform two-step CFRA using the RO configuration information in the four-step CBRA resource information, which seriously affects the communication effect.

[0253] Therefore, according to an embodiment of the present disclosure, when a 4-step contention random access (CBRA) resource of a designated release is not configured in a bandwidth portion (BWP) selected by a terminal, or when a 4-step CBRA resource of a designated release is configured in the BWP and the 4-step CBRA resource of the designated release is not shared, the RO configuration information in the resource information of the 2-step CFRA should be configured. Thus, when the terminal cannot perform 2-step CFRA using the configuration information in the 4-step CBRA resource information, the terminal can perform CFRA based on the RO configuration information in the configured 2-step CFRA resource information, ensuring that 2-step CFRA can be performed smoothly.

[0254] In one embodiment, the designated release is determined based on an instruction from a network side device or is determined based on a protocol.

[0255] In one embodiment, the specified release includes at least one of a legacy release and Release 17. In one embodiment, the legacy release includes at least one of Release 15 and Release 16.
