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 device for configuring non-contention random access, a communication device, and a computer-readable storage medium. [Background technology]

[0002] In some scenarios, the terminal can initiate random access. When the random access is divided by step, it can include two-step random access and four-step random access. When the random access is divided by contention type, it can include contention-based random access (CBRA) and contention-free random access (CFRA).

[0003] For the case of two-step CFRA, after two-step CFRA is initiated, the terminal needs to start 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 first needs to determine 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 two-step CBRA configuration information or the four-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, multiple CBRA configuration information can be configured in a terminal. 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.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure, but it is clear that the described embodiments are only some of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments that can be obtained by a person skilled in the art without any creative work are within the scope of protection of the present disclosure.

[0022] 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," "an," 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. Furthermore, the term "and / or" as used herein refers to any and all possible combinations of one or more of the associated listed items.

[0023] In embodiments of the present disclosure, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that such information should not be limited to these terms. These terms are merely used to distinguish between the same types of information. For example, first information can be referred to as second information, and similarly, second information can be referred to as first information, without departing from the scope of embodiments of the present disclosure. Depending on the context, the word "if" 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 describe magnitude relationships. However, those skilled in the art will understand that "greater" also means "greater than," "smaller" also means "less than," "higher" also means "more than," and "lower" also means "less than."

[0025] After initiating the two-step CFRA, the terminal needs to start the CFRA in a random access occasion (RO) (which can also be referred to as a physical random access channel occasion), so the terminal first needs to 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. The information element occasionsTwoStepRA further includes the content of two parts: one part is RO configuration information indicated by rach-ConfigGenericTwoStepRA; the other part is the correspondence between the synchronization signal block (SSB) and the RO indicated by ssb-PerRACH-OccassionTwoStepRA. 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 occasionsTwoStepRA in the CFRA configuration information is rach-ConfigGenericTwoStepRA by default. In this 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 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 RO resource information of Release 17 CBRA is configured in the terminal, and the RO resource information of Release 17 2-step CBRA can include RO resource information of multiple CBRAs, for example, including RO resource information of multiple 2-step CBRAs and RO resource information of multiple 4-step CBRAs.

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

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

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

[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 contention-free random access (CFRA) is initiated.

[0036] In step S102, if there is no individual random access occasion (RO) resource information configured 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 the two-step CFRA is initiated, the terminal needs to determine the 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 the RO to initiate the 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 the two-step CBRA or the RO resource information of the four-step CBRA.

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

[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 the instruction of the network side device. For example, if the specified release indicated by the network side device 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. For example, if the specified release indicated by the network side device 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.

[0042] The terminal may also determine the specified release based on the protocol. For example, if the specified release agreed upon 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. For example, if the specified release agreed upon 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 designated 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 synchronization signal blocks (SSBs) and ROs.

[0045] In one embodiment, the RO resource information may include two parts of content: RO configuration information and the correspondence relationship between SSB and RO. The terminal's determination of 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 SSB and 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] If only the RO configuration information in the RO resource information is 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 based on 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 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 subsequent embodiments.

[0048] Hereinafter, firstly, some embodiments will be exemplarily described to illustrate how 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 four-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. If there is no individual random access occasion (RO) resource information configured in the CFRA configuration information for the terminal, determining RO resource information for the initiated two-step CFRA based on RO resource information for 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 RO configuration information in the RO resource information of the four-step CBRA of the designated release as 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 RO configuration information in the RO resource information of the four-step CBRA of the specified release as 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 the plurality of four-step CBRAs of Release 17 is determined as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0058] In one embodiment, the specified release may be Release 17, and since Release 17 allows different CBRA configuration information to be configured for different features, the terminal may be configured with multiple 4-step CBRA RO resource information for 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 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 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 the RO configuration information in some resource information among the RO resource information of multiple Rel-17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 2-step CFRA, and the some resource information can be determined based on a pre-defined Rel-17 4-step CBRA configuration information list. For example, multiple RO configuration information can be 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.

[0061] Furthermore, 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 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 four-step CBRAs 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 RO resource information of the Release-17 four-step CBRA is received, determining RO configuration information in some or all of the RO resource information of the plurality of Release-17 four-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 four-step CBRA of Release 17 is not received, 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 four-step CBRA of the legacy release.

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

[0064] For example, when 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 Release-17 four-step CBRA is received, the terminal may determine the RO configuration information in some or all of the RO resource information of the multiple Release-17 four-step CBRAs as the RO configuration information in the RO resource information of the initiated two-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 is not 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.

[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 four-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 four-step CBRA, determining RO configuration information in some or all of the RO resource information of the plurality of Release-17 four-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 four-step CBRA 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 four-step CBRA of a legacy release.

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

[0068] For example, if the device 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 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 the initiated two-step CFRA based on the RO resource information of the four-step CBRA of Release 17, the terminal may determine the RO configuration information of the initiated two-step CFRA based on the RO configuration information of the four-step CBRA of the legacy release.

[0070] In one embodiment, the capabilities of the terminal 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 from the features, determine RO resource information of one or more four-step CBRAs corresponding to the supported features from the RO resource information of multiple four-step CBRAs of Release 17, and further determine RO configuration information in the RO resource information of the initiated two-step CFRA from the determined RO resource information of the one or more four-step CBRAs.

[0071] For example, if a network side device configures the RO resource information of four Release-17 four-step CBRAs for a terminal for four types of features, i.e., Slicing, SDT, CE, and Redcap, and the terminal's capability only supports two of these features, i.e., CE and Redcap, the terminal can determine the RO resource information of two four-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four Release-17 four-step CBRAs, and then use the determined RO resource information of the two four-step CBRAs to determine the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0072] In one embodiment, the step of determining RO configuration information in the RO resource information of some or all of the Release-17 4-step CBRAs among the 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 determining, based on the 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 it does not determine the RO configuration information in the RO resource information of some or all of the plurality of 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 2-step CFRA, it 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; For example, based on its own implementation, the terminal may determine the RO configuration information in some of 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.

[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 the above-mentioned embodiments such as instructions from the network-side device. 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 Release-17 4-step CBRAs 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 Release-17 4-step CBRAs 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 RO configuration information in the RO resource information of the four-step CBRA of the specified release as 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 Release 17 allows different CBRA configuration information to be configured for different features, the terminal may 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 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 that the RO configuration information in some of the RO resource information of at least a plurality of Rel-17 4-step CBRAs is the 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 Rel-17 4-step CBRA configuration information list, for example, by arranging a plurality of 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.

[0081] Furthermore, 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 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 CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: determining RO configuration information in part or all of the RO resource information of the four-step CBRA of the legacy release and the RO resource information of the plurality of four-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated two-step CFRA when an instruction from the network side device to determine RO resource information of the initiated two-step CFRA is received 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 method comprises: If an instruction from the network side device to determine RO resource information for 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 is not received, the method further includes determining RO configuration information in the RO resource information of the initiated two-step CFRA based on the RO resource information of the four-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 the RO resource information of an initiated two-step CFRA based on the RO resource information of a four-step CBRA of a legacy release and the RO resource information of a four-step CBRA of Release 17, the RO configuration information in some or all of the resource information 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 can be determined as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0085] 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 four-step CBRA of the legacy release and the RO resource information of the four-step CBRA of Release 17 is not 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 four-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 CBRAs 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 the initiated two-step CFRA based on RO resource information of the four-step CBRA of Release 17, determining RO configuration information in part or all of the RO resource information of the four-step CBRA of the legacy release and the RO resource information of the plurality of four-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 four-step CBRA 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 four-step CBRA of a legacy release.

[0087] In one embodiment, the terminal may determine, based on its own capabilities, whether 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.

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

[0089] If your 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, you can determine the RO configuration information of an initiated 2-step CFRA based only on the RO configuration information of the RO resource information of a legacy release 4-step CBRA.

[0090] In one embodiment, the capabilities of the terminal 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 from the features. When the terminal determines RO resource information for an initiated two-step CFRA based on at least the RO resource information of a Release-17 four-step CFRA, the terminal may determine RO resource information for one or more four-step CBRAs corresponding to the supported features from the RO resource information of multiple Release-17 four-step CBRAs, and may further determine RO configuration information in the RO resource information of the initiated two-step CFRA from the determined RO resource information of the one or more four-step CBRAs.

[0091] For example, if a network side device configures the RO resource information of four Release-17 four-step CBRAs for a terminal for four types of features, i.e., Slicing, SDT, CE, and Redcap, and the terminal's capability only supports two of these features, i.e., CE and Redcap, the terminal can determine the RO resource information of two four-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four Release-17 four-step CBRAs, and then use the determined RO resource information of the two four-step CBRAs to determine the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0092] In one embodiment, the step of determining RO configuration information in the RO resource information of some or all of the Release-17 4-step CBRAs among the 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 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 determine the RO configuration information in the RO resource information of the initiated two-step CFRA based only on the RO resource information of the four-step CBRA of the legacy release.

[0096] The following describes, in some embodiments, how to determine the RO resource information of the initiated two-step CFRA when the entire RO resource information is 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 correspondence relationship. If there is no individual random access occasion (RO) resource information configured in the CFRA configuration information for the terminal, determining RO resource information for the initiated two-step CFRA based on RO resource information for contention random access (CBRA) of a designated release includes the following step S601:

[0098] In step S601, if there is no correspondence between the individual RO configuration set in the configuration information of the CFRA for the terminal and the RO configuration information in 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.

[0099] In one embodiment, if the RO resource information includes RO configuration information and the correspondence relationship, i.e., if there is no correspondence relationship between an individual RO configuration configured in the configuration information of the CFRA for the terminal and the RO configuration information, 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 RO configuration information in the RO resource information of the two-step CBRA of the designated release as 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 the plurality of two-step CBRAs of Release 17 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 Release 17 allows different CBRA configuration information to be configured for different features, multiple two-step CBRA RO resource information for Release 17 can be configured in the terminal.

[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 the RO configuration information in some resource information among 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, 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 can be 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] Furthermore, 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 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 from a network side device to determine RO resource information of the initiated two-step CFRA based on RO resource information of a Release-17 two-step CFRA is received, determining RO configuration information in part 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; The method comprises: 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 CFRA of Release 17 is not received, the method further includes determining 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.

[0110] In an embodiment, the terminal may determine, based on an instruction from a 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 the initiated two-step CFRA based on the RO resource information of the Release-17 two-step CBRA is received, the terminal may 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.

[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 is not 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.

[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: 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, 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; 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 one embodiment, the terminal may determine, based on its own capabilities, whether 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.

[0115] For example, if the Rel. 17 ...

[0116] If the terminal capability 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 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.

[0117] In one embodiment, the capabilities of the terminal 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 from the features, determine RO resource information of one or more two-step CBRAs corresponding to the supported features from the RO resource information of multiple two-step CBRAs in Release 17, and further determine the determined RO resource information of one or more two-step CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA.

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

[0119] In one embodiment, the step of determining RO configuration information in the RO resource information of some or all of the Release-17 two-step CBRAs among the plurality of 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 the RO resource information of some or all of the Release 17 two-step CBRAs among the plurality of 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 it does not determine the RO configuration information in the RO resource information of some or all of the plurality of two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA, it 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 the RO configuration information in some of the RO resource information of multiple Release 17 2-step CBRAs as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0121] 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 among the plurality of Release-17 4-step CBRAs 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 the above-mentioned embodiments such as instructions from the network-side device. 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 in 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 in 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 RO configuration information in the RO resource information of the two-step CBRA of the designated release as 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 Release 17 allows different CBRA configuration information to be configured for different features, the terminal may 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 that the RO configuration information in some of the RO resource information of at least a plurality of Release 17 two-step CBRAs is the RO configuration information in the RO resource information of the initiated two-step CFRA, the some resource information can be determined based on a predefined R17 two-step CBRA configuration information list, for example, the plurality of RO configuration information is 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.

[0128] Furthermore, 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 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 CBRAs 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 RO resource information of the two-step CBRA of the legacy release and 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 plurality of 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 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 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 the RO resource information of an initiated two-step CFRA based on the RO resource information of a two-step CBRA of a legacy release and the RO resource information of a two-step CBRA of Release 17, 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 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 is not 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 CBRAs 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 the initiated two-step CFRA based on RO resource information of the 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 plurality of 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 may determine, based on its own capabilities, whether 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.

[0135] For example, if the device 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 your capability does not support determining the RO resource information of the initiated two-step CFRA based on the RO resource information of the Release-17 two-step CBRA, you can determine the RO configuration information of the initiated two-step CFRA based only on the RO configuration information of the legacy release two-step CBRA.

[0137] In one embodiment, the capabilities of the terminal 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 from the features. 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 RO resource information of one or more two-step CBRAs corresponding to the supported features from the RO resource information of multiple Release-17 two-step CBRAs, and may further determine RO configuration information in the RO resource information of the initiated two-step CFRA from the determined RO resource information of the one or more two-step CBRAs.

[0138] For example, if 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, i.e., Slicing, SDT, CE, and Redcap, and the terminal's capability only supports two of these features, i.e., CE and Redcap, the terminal can determine the RO resource information of two two-step CBRAs corresponding to the CE and Redcap features from the RO resource information of four two-step CBRAs in Release 17, and then use the determined RO resource information of the two two-step CBRAs to determine the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0139] In one embodiment, the step of determining RO configuration information in the RO resource information of some or all of the Release-17 two-step CBRAs among the plurality of 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 determine the RO configuration information in the RO resource information of the initiated two-step CFRA based only on the RO resource information of the two-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 for the initiated two-step CFRA based on RO resource information for 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 one embodiment, since the RO resource information of the two-step CFRA includes two parts: RO configuration information and the correspondence relationship between the SSB and the RO. In addition to determining the RO configuration information in the RO resource information of the two-step CFRA, it also needs to determine the correspondence relationship between the SSB and the RO in the RO resource information of the two-step CFRA. Furthermore, the terminal can determine the RO on which the two-step CFRA is to be performed based on the determined RO configuration information and the correspondence relationship between the SSB and the RO.

[0146] In one embodiment, the step of determining the correspondence between the SSB and the RO in the 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 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.

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

[0148] In one embodiment, the step of determining the correspondence between the SSB and the RO in the 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 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.

[0149] After the terminal determines the RO configuration information in the RO resource information of the CBRA of the designated 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 designated release) pre-configured in the terminal by the network side device.

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

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

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

[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, which can communicate with a terminal, and 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, and 6G, such as base stations and core networks.

[0154] As shown in FIG. 11, the method for indicating random access occasion resource information can 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 configured in the CFRA configuration information for the terminal, instruct the terminal to 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.

[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, the network side device determines 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 the RO to initiate the 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 network side device 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 for an initiated two-step CFRA based on RO resource information for a CBRA of a specified release. Even if RO resource information for a legacy release and RO resource information for a CBRA of Release 17 are configured for a terminal, the terminal can accurately determine which RO resource information for a CBRA of a specified release should be used to determine RO resource information for an initiated two-step CFRA. This avoids a technical problem that, when a terminal is faced with RO resource information for CBRA of multiple releases, it is difficult to determine which RO resource information for a CBRA of a specified release should be used to determine RO resource information for 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, instructing the terminal to determine RO resource information for the initiated two-step CFRA based on RO resource information for a contention random access (CBRA) of a designated 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 set 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 the RO resource information of the initiated two-step CFRA based on the RO resource information of the contention random access (CBRA) of a specified release, and can also more accurately instruct the terminal to set the RO resource information of the 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 designated 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 synchronization signal blocks (SSBs) and ROs.

[0164] In one embodiment, the RO resource information may include two parts of content: RO configuration information and the correspondence between SSB and RO. The terminal's determination of 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 between SSB and 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] If 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 based on 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 correspondence 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 correspondence relationship between the SSB and the RO will be described in subsequent embodiments.

[0167] The following first describes, by way of example, how to instruct a terminal to determine RO configuration information in the RO resource information of an initiated two-step CFRA based on RO configuration information in the RO resource information of a four-step CBRA in some embodiments.

[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, a step of determining RO resource information of the initiated two-step CFRA based on RO resource information of a designated release 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 instructing 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 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 2-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 instructing 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 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 2-step CFRA includes the following step S1401:

[0176] In step 1401, the terminal is instructed to determine the RO configuration information in some or all of the resource information 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.

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

[0178] In this case, the network side device may instruct the terminal to determine the RO configuration information in some (may be one or more) 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, 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 the RO configuration information in some resource information of the RO resource information of multiple Rel. 17 4-step CBRAs as the 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 Rel. 17 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, the network side device instructing the terminal to determine the RO configuration information in the total 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 total resource information are available to the terminal.

[0181] In one embodiment, the step of instructing the terminal to determine RO configuration information in part or all of the RO resource information of a plurality of Release-17 four-step CBRAs as RO configuration information in the RO resource information of the initiated two-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 Release-17 4-step CBRAs 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 Release-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 Release-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 two-step CFRA based on the RO configuration information in the RO resource information of the four-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 four-step CBRA of the legacy release.

[0184] In one embodiment, the step of instructing the terminal to determine RO configuration information in part or all of the RO resource information of a plurality of Release-17 four-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 four-step CBRA, instructing the terminal to determine 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; 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 four-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 two-step CFRA based on RO configuration information in the RO resource information of the four-step CBRA of a legacy release.

[0185] 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 multiple four-step CBRAs in Release 17 as RO configuration information in the RO resource information of the initiated two-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 two-step CFRA based on the RO resource information of the four-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 four-step CBRA of the legacy release.

[0188] In one embodiment, the terminal capabilities 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 based on the terminal capabilities, 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, if the network side device configures the RO resource information of four Release-17 4-step CBRAs for the terminal for four features, i.e., Slicing, SDT, CE, and Redcap, and determines based on the terminal's capabilities that the terminal supports only two of the features, i.e., CE and Redcap, the network side device can instruct the terminal to determine the RO resource information of two Release-17 4-step CBRAs corresponding to the CE and Redcap features in the RO resource information of the four Release-17 4-step CBRAs, 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 instructing 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 4-step CBRA of the specified release as the RO configuration information in the RO resource information of the initiated 2-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 Release 17 allows different CBRA configuration information to be configured for different features, the terminal may 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 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, by arranging multiple RO configuration information in a 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.

[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 all resource information are available to the terminal.

[0196] In one embodiment, when 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 four-step CBRA of a legacy release and RO resource information of a four-step CBRA of Release 17, the terminal can determine, based on the instruction, 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 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 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 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 four-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 the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the plurality of 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA includes: Instructing the terminal to determine 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 CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 2-step CFRA, when the terminal supports 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 comprises: If the terminal does not support determining RO resource information of the initiated two-step CFRA based on RO resource information of the four-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 two-step CFRA based on RO configuration information in the RO resource information of the four-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 in 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 in the legacy release and the RO resource information of multiple four-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA.

[0201] If it is determined based on the capabilities of the terminal 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 capabilities 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 based on the terminal capabilities. When the terminal determines the RO resource information of the initiated two-step CFRA based at least on the RO resource information of the Release-17 four-step CFRA, the network side device may determine RO resource information of one or more four-step CBRAs corresponding to the features supported by the terminal in the RO resource information of 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 based on the determined RO resource information of the one or more four-step CBRAs.

[0203] For example, if the network side device configures the RO resource information of four Release-17 4-step CBRAs for the terminal for each of the four features, i.e., Slicing, SDT, CE, and Redcap, and determines based on the terminal's capabilities that the terminal supports only two of the features, i.e., CE and Redcap, the network side device can determine the RO resource information of two Release-17 4-step CBRAs corresponding to the CE and Redcap features in the RO resource information of the four Release-17 4-step CBRAs, 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 instructing 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 if there is no individual random access occasion (RO) resource information configured in the configuration information of the CFRA for the terminal, 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 designated release includes the following steps:

[0205] In step S1601, if there is no correspondence between the 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, if the RO resource information includes RO configuration information and the correspondence relationship, i.e., if there is no correspondence relationship between an individual RO configuration configured in the configuration information of the CFRA for the terminal and the RO configuration information, the network side device instructs the terminal to 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.

[0207] 17 is a schematic flowchart of another method for instructing 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 a 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 instructing 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 RO configuration information in the RO resource information of the two-step CBRA of a designated release as 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 the RO configuration information in some or all of the resource information 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.

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

[0213] In this case, the network side device may instruct the terminal to determine the RO configuration information in some (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 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, 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.

[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 all resource information are available to the terminal.

[0216] 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 Release-17 two-step CBRA, the terminal can determine, based on the instruction, the RO configuration information in some or all of the RO 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.

[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 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; 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, 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 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 multiple two-step CBRAs in 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 the initiated two-step CFRA based on the RO resource information of the Release-17 two-step CBRA, the terminal may 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.

[0221] If it is determined based on the capabilities of the terminal 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 capabilities 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 based on the terminal capabilities, the network side device can determine RO resource information of one or more two-step CBRAs 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 RO resource information of the one or more two-step CBRAs.

[0223] For example, if a network 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, and 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 instructing 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 RO configuration information in the RO resource information of the two-step CBRA of a designated release as 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 Release 17 allows different CBRA configuration information to be configured for different features, the terminal may 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 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 CBRAs as RO configuration information in the RO resource information of the initiated two-step CFRA, the some resource information can be determined based on a predefined R17 two-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.

[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 all resource information are available to the terminal.

[0230] In one embodiment, when 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 two-step CBRA of a legacy release and RO resource information of a two-step CBRA of Release 17, the terminal can determine, based on the instruction, 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.

[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 two-step CBRA of legacy release and RO resource information of multiple two-step CBRA of Release 17 as RO configuration information in RO resource information of the initiated two-step CFRA includes: Instructing the terminal to determine RO configuration information in part or all of the RO resource information of the two-step CBRA of a legacy release and the RO resource information of the plurality of two-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated two-step CFRA, 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; 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 the 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 two-step CBRA of Release 17, 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 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.

[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 capabilities 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 based on the terminal capabilities, and when instructing the terminal to determine RO resource information for the initiated two-step CFRA based at least on the RO resource information of the Release-17 two-step CFRA, the network side device may determine RO resource information for one or more two-step CBRAs corresponding to the supported features in the RO resource information of multiple Release-17 two-step CBRAs, and further instruct the terminal to determine RO configuration information in the RO resource information of the initiated two-step CFRA based on the determined RO resource information of the one or more two-step CBRAs.

[0237] For example, if 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, i.e., Slicing, SDT, CE, and Redcap, and the network device determines that the terminal only supports two of the features, i.e., 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 the 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 CBRAs initiated in the determined RO resource information of the two two-step CBRAs.

[0238] 20 is a schematic flowchart of another method for instructing 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 CFRA configuration information for the terminal, the step of instructing the terminal to determine RO resource information for the initiated two-step CFRA based on RO resource information for a designated release of contention random access (CBRA) further includes the following step S2001.

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

[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 based on 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; To perform RO for two-step CFRA, the terminal needs to determine RO configuration information and also 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 based on 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 designated release as the RO configuration information in the RO resource information of the initiated 4-step CFRA, and then may further instruct the terminal to determine the correspondence between synchronization signal blocks (SSBs) and ROs in the RO resource information of the 4-step CBRA of the designated release as the correspondence between SSBs and ROs in the RO resource information of the initiated 4-step CFRA, that is, the RO configuration information and the correspondence between SSBs and ROs may 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 the correspondence relationship between the synchronization signal block (SSB) and the RO in the RO resource information of the initiated 4-step CFRA based on the correspondence relationship between the SSB and the 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] Furthermore, 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. The correspondence relationship between SSBs and ROs can be expressed by values ​​such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16, etc., and the network device can select one of the values, 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 the bandwidth portion (BWP) selected by the terminal.

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

[0247] Therefore, based on the embodiment of the present disclosure, a two-step contention-free random access (CFRA) resource is configured only when a two-step contention-free random access (CBRA) resource of a specified release is configured in the bandwidth portion (BWP) selected by the terminal, thereby ensuring that two-step CFRA can be smoothly performed using the two-step CBRA resource even if the terminal's two-step CFRA resource is unavailable.

[0248] If a two-step contention random access (CBRA) resource of the 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 designated 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 two-step CFRA when a four-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 four-step CBRA resource of a specified release is set in the BWP and the four-step CBRA resource of the specified release is not shared.

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

[0253] Therefore, according to an embodiment of the present disclosure, if 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 if 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 terminal must configure RO configuration information in the 2-step CFRA resource information. Thus, if 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 smooth performance of 2-step CFRA.

[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 designated 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.

[0256] Corresponding to the above-mentioned embodiments of the method for determining random access occasion resource information, the method for indicating random access occasion resource information, and the method for configuring non-contention random access, the present disclosure further provides embodiments of an apparatus for determining random access occasion resource information, an apparatus for indicating random access occasion resource information, and an apparatus for configuring non-contention random access.
