Abstract

The present disclosure relates to a method and an apparatus for determining and indicating random access occasion resource information. The method for determining random access occasion resource information includes initiating a 4-step non-contention random access (CFRA); and, if there is no individual random access occasion (RO) resource information configured in the RO configuration information of the CFRA for the terminal, determining the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of a 4-step contention random access (CBRA) of a specified release. According to the present disclosure, the terminal can determine the RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA of a specified release.

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, an apparatus for determining random access occasion resource information, an apparatus for indicating random access occasion resource information, a communication apparatus, and a computer-readable storage medium. [Background technology]

[0002] In some scenarios, a terminal may initiate random access. Random access may be classified according to steps, including two-step random access and four-step random access. Random access may be classified according to contention type, including contention-based random access (CBRA) and contention-free random access (CFRA).

[0003] For the case of 4-step CFRA, after initiating 4-step CFRA, the terminal needs to start 4-step CFRA on a random access occasion, also called a physical random access channel occasion (PRACH occasion, RO), so the terminal needs to first determine the RO resource information for 4-step CFRA.

[0004] However, the network side may not indicate the RO resource in the CFRA configuration information, in which case the terminal may use the RO resource in the 4-step CBRA configuration information.

[0005] However, with the development of random communication technology, application scenarios have expanded, and different CBRA configuration information can be configured for various features in order to adapt to the features of various scenarios, so that a UE can configure multiple CBRA configuration information. This means that if the UE cannot determine the RO resource information in the CFRA configuration information, it is difficult to determine which RO resource in the CBRA configuration information to use for the CFRA. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of this, to solve the technical problems in the related art, the embodiments of the present disclosure propose a method for determining random access occasion resource information, a method for indicating random access occasion resource information, an apparatus for determining random access occasion resource information, an apparatus for indicating random access occasion resource information, a communication device, and a computer-readable storage medium. [Means for solving the problem]

[0007] According to a first aspect of an embodiment of the present invention, there is proposed a method for determining random access occasion resource information, which is executed by a terminal, the method including: initiating a 4-step non-contention random access (CFRA); and, if there is no individual random access occasion (RO) resource information configured in RO configuration information of the CFRA for the terminal, determining RO resource information of the initiated 4-step CFRA based on random access occasion (RO) resource information of a 4-step contention random access (CBRA) of a specified release.

[0008] According to a second aspect of an embodiment of the present invention, there is proposed a method for indicating random access occasion resource information, which is executed by a terminal, the method including: initiating a four-step non-contention random access (CFRA); and, if there is no individual random access occasion (RO) resource information configured in RO configuration information of the CFRA for the terminal, instructing the terminal to determine RO resource information for the initiated four-step CFRA based on random access occasion (RO) resource information of a four-step contention random access (CBRA) of a designated release.

[0009] According to a third aspect of an embodiment of the present disclosure, there is proposed an apparatus for determining resource information of a random access occasion, the apparatus including one or more processors, wherein the processors are configured to initiate a four-step non-contention random access (CFRA) and, if there is no individual random access occasion (RO) resource information configured in the RO configuration information of the CFRA for a terminal, determine RO resource information of the initiated four-step CFRA based on random access occasion (RO) resource information of a four-step contention random access (CBRA) of a specified release.

[0010] According to a fourth aspect of an embodiment of the present disclosure, there is proposed an apparatus for indicating random access occasion resource information, the apparatus including one or more processors, wherein the processors are configured to initiate a four-step non-contention random access (CFRA) and, if there is no individual random access occasion (RO) resource information configured in RO configuration information of the CFRA for the terminal, to instruct the terminal to determine RO resource information for the initiated four-step CFRA based on random access occasion (RO) resource information of a four-step contention random access (CBRA) of a specified release.

[0011] According to a fifth aspect of an embodiment of the present disclosure, there is proposed a communication device including a processor and a memory for storing a computer program, the computer program being executed by the processor to realize the above-mentioned method for determining random access occasion resource information.

[0012] According to a sixth aspect of the embodiment of the present disclosure, there is provided a communication device, comprising: a processor; A communication device is proposed, comprising: a memory for storing a computer program, said computer program, when executed by a processor, realizing the above method for indicating random access occasion resource information.

[0013] According to a seventh aspect of an embodiment of the present disclosure, there is proposed a computer-readable storage medium for storing a computer program, which, when executed by a processor, implements steps in the above-mentioned method for determining random access occasion resource information.

[0014] According to an eighth aspect of the present disclosure, there is provided a computer-readable storage medium for storing a computer program, the computer program, when executed by a processor, realizing the steps of the method for indicating random access occasion resource information described above.

[0015] According to an embodiment of the present invention, a terminal can determine RO resource information of an initiated four-step CFRA based on RO resource information of a four-step CBRA of a specified release. This allows the terminal to accurately determine which release's RO resource information of a four-step CBRA to use to determine the RO resource information of the initiated four-step CFRA, even if RO resource information of a legacy release and RO resource information of a four-step CBRA of Release 17 are configured. This avoids a technical problem in which, when the terminal is faced with RO resource information of four-step CBRAs of multiple releases, it is difficult to determine which release's RO resource information of a four-step CBRA to use to determine the RO resource information of a four-step CFRA.

[Figure 14] 1 is a schematic block diagram of an apparatus for determining random access occasion resource information according to an embodiment of the present disclosure; DETAILED DESCRIPTION OF THE INVENTION

[0018] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of the embodiments of the present disclosure. It is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and are not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present disclosure.

[0019] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood that the term "and / or," as used herein, refers to and includes any and all possible combinations of one or more of the associated listed items.

[0020] In the 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 used only to distinguish between the same types of information. For example, first information may be referred to as second information without departing from the scope of the present disclosure. Similarly, second information may be referred to as first information. Depending on the context, for example, the word "upon" used in this specification may be interpreted as "if," "when," or "depending on the decision."

[0021] For simplicity and ease of understanding, this specification uses the terms "greater than" or "smaller," "higher" or "lower" when characterizing magnitude relationships. However, those skilled in the art will understand that the term "greater than" also includes "greater than or equal to," the term "smaller" also includes "less than or equal to," the term "higher" also includes "more than or equal to," and the term "lower" also includes "less than or equal to."

[0022] After initiating the 4-step CFRA, the terminal needs to start the CFRA in a random access occasion RO (also called a physical random access channel occasion), so the terminal needs to first determine the RO resource information for the 4-step CFRA.

[0023] Typically, the RO resource information for 4-step CFRA includes two parts in the CFRA configuration: one part is the RO configuration information, and the other part is the association between the synchronization signal block (SSB) and the RO. Based on these two parts, the terminal can determine the RO to start the 4-step CFRA.

[0024] However, there are cases where the network side does not indicate RO resource information in the CFRA configuration information. For example, if the CFRA configuration information does not include RO configuration information, the terminal can use the RO resource in the 4-step CBRA configuration information (indicated by the information element RACH-ConfigCommon indication).

[0025] However, with the development of random communication technology, application scenarios are also expanding. For example, in R17, different CBRA configuration information can be configured for different features to suit various scenarios, such as slicing, small data transmission (SDT), coverage enhancement (CE), and reduced capability (Redcap). That is, a terminal is configured with RO resource information for the 4-step CBRA in Release 17. The RO resource information for the 4-step CBRA in Release 17 can include RO resource information for multiple 4-step CBRAs.

[0026] The terminal is also configured with RO resource information of the 4-step CBRA of a legacy release, such as the RO resource information of the 4-step CBRA of R15 and Release 16. In the legacy release, the network side device does not configure different CBRA configuration information for the terminal for each of the above features, but configures only one RO resource information of the 4-step CBRA for the terminal.

[0027] Therefore, when a terminal is configured with RO resource information of the 4-step CBRA of a legacy release and RO resource information of the 4-step CBRA of Release 17, RO resource information of the 4-step CBRA of multiple releases exists for the terminal. When faced with RO resource information of the 4-step CBRA of multiple releases, it is difficult for the terminal to determine which RO resource information of the 4-step CBRA of a release to use to determine the RO resource information of the 4-step CFRA. The following embodiments of the present disclosure are proposed mainly to solve this technical problem.

[0028] 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 shown in this embodiment can be executed by a terminal, and the terminal can communicate with a network side device. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. 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.

[0029] As shown in FIG. 1, the method for determining random access occasion resource information may include the following steps S101 and S102. In step S101, a four-step non-contention random access (CFRA) is initiated. In step S102, if there is no individual random access occasion (RO) resource information set in the RO configuration information of the CFRA for the terminal, determine the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the specified release.

[0030] In one embodiment, the UE may initiate a 4-step CFRA in a specific case, where the manner of initiating the 4-step CFRA is: The initiation includes at least one of initiation by a physical downlink control channel (PDCCH) order, initiation by a system information (SI) request, and initiation by a handover command.

[0031] After initiating the 4-step CFRA, the terminal needs to determine RO resource information for the 4-step CFRA, for example, to determine whether RO resource information individually configured for the terminal exists in the CFRA configuration information. If RO resource information individually configured for the terminal exists, the terminal can determine the RO to initiate the 4-step CFRA based on the RO resource information individually configured for the terminal. If RO resource information individually configured for the terminal does not exist, the terminal can determine RO resource information for the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA.

[0032] According to an embodiment of the present disclosure, a terminal can determine RO resource information of an initiated four-step CFRA based on RO resource information of a four-step CBRA of a specified release. This allows the terminal to accurately determine which release's RO resource information of a four-step CBRA to use to determine the RO resource information of the initiated four-step CFRA, even if RO resource information of a legacy release and RO resource information of a four-step CBRA of Release 17 are configured. This avoids a technical problem in which, when the terminal is faced with RO resource information of four-step CBRAs of multiple releases, it is difficult to determine which release's RO resource information of a four-step CBRA to use to determine the RO resource information of the four-step CFRA.

[0033] In addition, in related technologies (for example, R15, R16), the information element corresponding to the 4-step CBRA configuration information is RACH-ConfigCommon, so RACH-ConfigCommon refers to the 4-step CBRA configuration information of the legacy release by default.

[0034] According to an embodiment of the present disclosure, the information element RACH-ConfigCommon can be adjusted to clarify which specific release is specified.

[0035] For example, the CBRA configuration in Release 17 can be distinguished from the CBRA configuration in legacy releases by a different suffix, such as RACH-ConfigCommon-r17.

[0036] For example, the CBRA configuration in Release 17 can be distinguished from the CBRA configuration in legacy releases by a different name, such as RACH-ConfigCommonExt-R17.

[0037] In one embodiment, the designated release is determined based on an instruction from a network-side device or based on a protocol.

[0038] The terminal may determine the designated release based on an instruction from the network side device. For example, if the designated release designated by the network side device is R17, the terminal determines RO resource information for the initiated 4-step CFRA based on random access occasion (RO) resource information for 4-step contention random access (CBRA) of Release 17. For example, if the designated release designated by the network side device is a legacy release, the terminal determines RO resource information for the initiated 4-step CFRA based on random access occasion (RO) resource information for 4-step contention random access (CBRA) of the legacy release.

[0039] The terminal may also determine the specified release based on a protocol. For example, if the release specified by the protocol agreement is R17, the terminal determines RO resource information for the initiated four-step CFRA based on random access occasion (RO) resource information for four-step contention random access (CBRA) of Release 17. For example, if the release specified by the protocol agreement is a legacy release, the terminal determines RO resource information for the initiated four-step CFRA based on random access occasion (RO) resource information for four-step contention random access (CBRA) of the legacy release.

[0040] In one embodiment, the specified release includes at least one of a legacy release and Release 17. In one embodiment, the legacy release includes at least one of Release 15 and Release 16.

[0041] 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, determining random access occasion (RO) resource information of an initiated 4-step CFRA based on the 4-step contention random access (CBRA) of a designated release includes the following step S202: In step S202, 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 of the RO resource information of the initiated 4-step CFRA.

[0042] In one embodiment, the manner of initiating the 4-step CFRA may include initiating by a PDCCH order, initiating by a system information request (SI request), and initiating by a handover command.

[0043] The RO configuration information and the correspondence relationship between SSB and RO mainly included in the RO resource information of the 4-step CBRA are the RO configuration information and the correspondence relationship between SSB and RO that the terminal needs to determine.

[0044] For the above three initiation methods, if the initiation method is initiated by a system information request (SI request) or by a handover command, the terminal must determine the RO configuration information and the correspondence between SSB and RO in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the specified release.

[0045] On the other hand, when the initiation method is initiation by PDCCH order, information such as an SSB index and a PRACH mask index is indicated in the PDCCH, and the terminal can determine the correspondence between the SSB and the RO based on this information. Therefore, the terminal can determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step CBRA of the specified release.

[0046] That is, for all of the above three initiation methods, the UE needs to determine RO configuration information in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the specified release. For example, the UE 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 of the RO resource information of the initiated 4-step CFRA. On the other hand, if the initiation method is initiated by a system information request (SI request) or initiated by a handover command, the UE needs to further determine a correspondence relationship between the SSB and the RO in the RO resource information of the initiated 4-step CFRA. The details of determining the correspondence relationship will be described in the following embodiments.

[0047] Furthermore, when the initiation method is initiation by PDCCH order, in this embodiment, the network side device does not indicate RO configuration information in the RO resource information of the CFRA, and the terminal may determine the RO configuration information of the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA.The network side device may indicate the RO configuration information in the RO resource information of the CFRA by downlink control information DCI (Downlink Control ROI Information) in the PDCCH, and the terminal may determine the RO configuration information of the RO resource information of the initiated 4-step CFRA based on the RO configuration information indicated by the DCI.

[0048] 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, determining RO configuration information in the RO resource information of the 4-step CBRA of the designated release as RO configuration information of the RO resource information of the initiated 4-step CFRA includes the following step S301: 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 4-step CFRA.

[0049] In one embodiment, the designated release may be a legacy release, in which case the UE 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 4-step CFRA.

[0050] 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 4-step CBRA of the specified release as RO configuration information of the RO resource information of the initiated 4-step CFRA includes the following step S401: In step S401, the RO configuration information in some or all of the RO resource information of the plurality of 4-step CBRAs of Release 17 is determined as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0051] In one embodiment, the specified release may be Release 17. Since different CBRA configuration information can be configured for different features in Release 17, the terminal can configure multiple 4-step CBRA RO resource information in Release 17.

[0052] 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 4-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 4-step CFRA.

[0053] In this case, the terminal determines RO configuration information in some resource information among multiple RO resource information of Rel-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA, where the some resource information can be determined based on a predefined Rel-17 4-step CBRA configuration information list, for example, multiple RO configuration information are arranged in order in the list, and the some resource information can be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0054] Furthermore, when the terminal determines the RO configuration information in the total resource information as the RO configuration information in the RO resource information of the initiated 4-step CFRA, it means that the RO configured by the RO configuration information in the total resource information is available to the terminal.

[0055] In one embodiment, the step of determining RO configuration information in some or all of 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 4-step CFRA includes: When an instruction to determine RO resource information of the initiated 4-step CFRA based on RO resource information of the Release-17 4-step CBRA is received from the network side device, the method includes a step of determining RO configuration information in some or all of the RO resource information of the multiple Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0056] The method comprises: The method further includes a step of determining RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release, when an instruction to determine RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of Release 17 is not received from the network side device.

[0057] In an embodiment, the terminal may, according to an instruction from a network side device, determine whether to determine RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs in Release 17 as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0058] For example, when receiving an instruction from a network-side device to determine RO resource information of an initiated 4-step CFRA based on RO resource information of a Release-17 4-step CBRA, the terminal may determine RO configuration information in some or all of the RO resource information of multiple Release-17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0059] On the other hand, if an instruction to determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of Release 17 is not received from the network side device, the RO configuration information in the RO resource information of the initiated 4-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.

[0060] In one embodiment, the step of determining RO configuration information in some or all of 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 4-step CFRA includes: If the terminal supports determining RO configuration information in the RO resource information of the initiated 4-step CFRA based on RO configuration information in the RO resource information of the Release-17 4-step CBRA, the method includes determining RO configuration information in some or all of the RO resource information of multiple Release-17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0061] The method comprises: If the terminal does not support determining RO resource information of the initiated 4-step CFRA based on RO resource information of the 4-step CBRA of Release 17, the method further includes determining RO configuration information in the RO resource information of the initiated 4-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0062] 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 4-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0063] For example, if the own capability supports determining the RO resource information of an initiated 4-step CFRA based on the RO resource information of a Release-17 4-step CBRA, the RO configuration information in some or all of the RO resource information of multiple Release-17 4-step CBRAs can be determined as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0064] On the other hand, if the terminal's capability 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 can determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0065] In one embodiment, the terminal capabilities may further include the terminal's support status for features such as Slicing, SDT, CE, and Redcap. The terminal may determine features supported by its own capabilities from the features. Then, the terminal may determine RO resource information of one or more 4-step CBRAs corresponding to the supported features from the RO resource information of multiple 4-step CBRAs in Release 17, and further determine the determined RO resource information of one or more 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0066] For example, if a network side device configures the RO resource information of four Release-17 4-step CBRAs for a terminal for four features, namely, Slicing, SDT, CE, and Redcap, and the terminal's capability supports only two of the features, namely, CE and Redcap, the terminal can determine the RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four Release-17 4-step CBRAs, and further 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 4-step CFRA.

[0067] In one embodiment, the step of determining 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 4-step CFRA includes: The method includes a step of determining, based on an implementation of the terminal, RO configuration information in the RO resource information of some or all of the Release 17 4-step CBRAs among the plurality of Release 17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0068] For example, if a terminal determines based on its own implementation that it will not determine the RO configuration information in the RO resource information of some or all of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA, it can determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0069] For example, based on its own implementation, the terminal may determine the RO configuration information in the RO resource information of some of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0070] For example, based on its own implementation, the terminal may determine the RO configuration information in the RO resource information of all of the Release 17 4-step CBRAs among the multiple Release 17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0071] The implementation of the terminal can be combined with the above-described embodiments of the instruction of the network-side device. For example, the network-side device instructs the terminal to determine 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 4-step CFRA. The terminal can select one of the plurality of Release-17 4-step CBRAs or determine the RO configuration information in the plurality of Release-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA based on its own implementation.

[0072] 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 4-step CBRA of the designated release as RO configuration information of the RO resource information of the initiated 4-step CFRA includes the following step S501:

[0073] 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 4-step CFRA.

[0074] In one embodiment, the specified release may include a legacy release and Release 17. Since different CBRA configuration information can be configured for different features in Release 17, a terminal can be configured with multiple 4-step CBRA RO resource information in Release 17.

[0075] 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 4-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 4-step CFRA.

[0076] Here, when the UE determines RO configuration information in some resource information among at least a plurality of RO resource information of Rel-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA, the some resource information may be determined based on a predefined Rel-17 4-step CBRA configuration information list. For example, a plurality of RO configuration information may be arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer greater than or equal to 1.

[0077] Furthermore, when the terminal determines the RO configuration information in the total resource information as the RO configuration information in the RO resource information of the initiated 4-step CFRA, it means that the RO configured by the RO configuration information in the total resource information is available to the terminal.

[0078] 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 4-step CFRA includes: When an instruction to determine RO resource information of the initiated 4-step CFRA is received from the network side device based on RO resource information of the 4-step CBRA of the legacy release and RO resource information of the 4-step CBRA of Release 17, the method includes a step of 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 4-step CFRA.

[0079] The method comprises: The method further includes, when an instruction to determine RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17 is not received from the network side device, determining RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0080] In one embodiment, the terminal can determine, according to an instruction from a 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 4-step CFRA.

[0081] For example, when an instruction to determine the RO resource information of an initiated 4-step CFRA is received from a network-side device based on the RO resource information of a 4-step CBRA of a legacy release and the RO resource information of a 4-step CBRA of Release 17, the RO configuration information in some or all of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of multiple 4-step CBRAs of Release 17 can be determined as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0082] On the other hand, if an instruction to determine the RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17 is not received from the network side device, the RO configuration information in the RO resource information of the initiated 4-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.

[0083] 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 4-step CFRA includes: If the terminal supports determining RO resource information of the initiated 4-step CFRA based on RO resource information of a Release 17 4-step CBRA, the method includes a step of determining RO configuration information in the RO resource information of the 4-step CBRA of the legacy release and 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 4-step CFRA.

[0084] The method comprises: If the terminal does not support determining RO resource information of the initiated 4-step CFRA based on RO resource information of the 4-step CFRA of Release 17, the method further includes determining RO configuration information in the RO resource information of the initiated 4-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0085] 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 4-step CFRA.

[0086] For example, if the capability supports determining the RO resource information of an initiated 4-step CFRA based on the RO resource information of a Release 17 4-step CBRA, the RO configuration information in the RO resource information of a legacy release 4-step CBRA and some or all of the RO resource information of multiple Release 17 4-step CBRAs can be determined as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0087] On the other hand, if the R&S 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 in Release 17, it can determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based only on the RO configuration information in the RO resource information of the 4-step CBRA in the legacy release.

[0088] In one embodiment, the terminal capabilities may include the terminal's support status for features such as Slicing, SDT, CE, and Redcap. The terminal can determine features supported by its own capabilities from the features. When the terminal determines the RO resource information of the initiated 4-step CFRA based on at least the RO resource information of the Release-17 4-step CFRA, the terminal can determine the RO resource information of one or more 4-step CBRAs corresponding to the supported features from the RO resource information of multiple Release-17 4-step CBRAs, and further determine the determined RO resource information of the one or more 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0089] For example, if a network side device configures the RO resource information of four Release-17 4-step CBRAs for a terminal for four features, namely, Slicing, SDT, CE, and Redcap, and the terminal's capability supports only two of the features, namely, CE and Redcap, the terminal can determine the RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four Release-17 4-step CBRAs, and further 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 4-step CFRA.

[0090] 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 4-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 4-step CFRA.

[0091] For example, the terminal's own implementation may determine the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release and some or all 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 4-step CFRA.

[0092] For example, the implementation of the terminal itself may 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 4-step CFRA.

[0093] For example, the implementation of the terminal itself may determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based only on the RO resource information of the 4-step CBRA of the legacy release.

[0094] 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 four-step CFRA initiation method includes at least one of initiating by a system information request (SI request) and initiating by a handover command. The method further includes the following step S601:

[0095] In step S601, the correspondence between the SSB and the RO in the RO resource information of the initiated 4-step CFRA is determined.

[0096] In one embodiment, as can be seen from the above-mentioned embodiment, in the above three initiation methods, the UE needs to determine RO configuration information in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the designated release. For example, the UE can determine the RO configuration information in the RO resource information of the 4-step CBRA of the designated release as the RO configuration information of the RO resource information of the initiated 4-step CFRA.

[0097] On the other hand, if the initiation method is initiated by a system information request (SI request) or by a handover command, the terminal needs to further determine a correspondence relationship between the SSB and the RO in the RO resource information of the initiated 4-step CFRA. Furthermore, the terminal can determine the RO to be used for the initiated 4-step CFRA based on the RO configuration information and the correspondence relationship.

[0098] In one embodiment, the step of determining the correspondence between SSB and RO in the RO resource information of the initiated four-step CFRA includes: The method includes a step of determining the correspondence between synchronization signal blocks (SSBs) and ROs in the RO resource information of the 4-step CBRA of the specified release as the correspondence between SSBs and ROs in the RO resource information of the initiated 4-step CFRA.

[0099] According to the above-mentioned embodiment, after the UE determines 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, it can further determine the correspondence relationship between the synchronization signal block (SSB) and the RO in the RO resource information of the 4-step CBRA of the designated release as the correspondence relationship between the SSB and the RO in the RO resource information of the initiated 4-step CFRA. That is, the RO configuration information and the correspondence relationship between the SSB and the RO may belong to the same RO resource information.

[0100] In one embodiment, the step of determining the correspondence between SSB and RO in the RO resource information of the initiated four-step CFRA includes: The method includes a step of determining a correspondence relationship between synchronization signal blocks (SSBs) and ROs in the RO resource information of the initiated 4-step CFRA based on a correspondence relationship between SSBs and ROs in the RO resource information of the 4-step CBRA of all releases that has been pre-configured in the terminal by a network side device (for example, by broadcast in a system message).

[0101] Based on the above-described embodiment, the terminal determines 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 can determine the correspondence relationship between the synchronization signal blocks (SSBs) and the ROs in the RO resource information of the initiated 4-step CFRA based on the correspondence relationship between the SSBs and the ROs in the RO resource information of the 4-step CBRA of all releases (not necessarily limited to the RO resource information of the 4-step CBRA of the specified release) pre-configured in the terminal by the network side device.

[0102] If there are multiple SSB-RO correspondence relationships in the RO resource information of the 4-step CBRA for all releases preconfigured in the terminal by the network-side device, the terminal can determine one SSB-RO correspondence relationship from among them. Here, the SSB-RO correspondence relationship is characterized by a value such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, or 16, and the terminal can select one of the values, for example, the maximum or minimum value.

[0103] In one embodiment, the step of determining the correspondence between SSB and RO in the RO resource information of the initiated four-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 four-step CFRA.

[0104] The following embodiment describes, from the network side, how a terminal determines RO resource information of an initiated 4-step CFRA in the case of a network-side device indication. Note that, the network-side device indication is just one way for a terminal to determine RO resource information of an initiated 4-step CFRA based on random access occasion (RO) resource information of a 4-step contention random access (CBRA) of a specified release. The terminal may also determine RO resource information of an initiated 4-step CFRA based on random access occasion (RO) resource information of a 4-step contention random access (CBRA) of a specified release according to a protocol agreement.

[0105] 7 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 shown in this embodiment can be performed by a network side device, which can communicate with a terminal, including but not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The network side device can include but is not limited to network side devices in communication systems such as 4G, 5G, and 6G, such as base stations and core networks.

[0106] As shown in FIG. 7, the method for indicating random access occasion resource information may include the following steps S701 and S702. In step S701, a four-step non-contention random access (CFRA) is initiated. In step S702, if there is no individual random access occasion (RO) resource information set in the RO configuration information of the CFRA for the terminal, instruct the terminal to determine the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the specified release.

[0107] In one embodiment, the network side device can initiate the UE to perform the 4-step CFRA in a specific case. The manner of initiating the 4-step CFRA is as follows: The initiation includes at least one of initiation by a physical downlink control channel order (PDCCH order), initiation by a system information request (SI request), and initiation by a handover command.

[0108] After the network side device initiates the UE to perform a 4-step CFRA, the UE needs to determine RO resource information for the 4-step CFRA, for example, determine whether RO resource information individually configured for the UE is present in the CFRA configuration information. If RO resource information individually configured for the UE is present, the UE can determine the RO on which to initiate the 4-step CFRA based on the RO resource information individually configured for the UE. If RO resource information individually configured for the UE is not present, the UE can determine the RO resource information for the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA.

[0109] According to an embodiment of the present disclosure, a network side device can instruct a terminal to determine RO resource information of an initiated 4-step CFRA based on RO resource information of a 4-step CBRA of a specified release. This allows the terminal to accurately determine which release's RO resource information of the 4-step CBRA to use to determine RO resource information of the initiated 4-step CFRA, even if RO resource information of a legacy release and RO resource information of a 4-step CBRA of Release 17 are configured. This avoids a technical problem in which, when the terminal is faced with RO resource information of 4-step CBRAs of multiple releases, it is difficult to determine which release's RO resource information of the 4-step CBRA to use to determine RO resource information of the 4-step CFRA.

[0110] In addition, in related technologies (for example, R15, R16), the information element corresponding to the 4-step CBRA configuration information is RACH-ConfigCommon, so RACH-ConfigCommon refers to the 4-step CBRA configuration information of the legacy release by default.

[0111] According to an embodiment of the present disclosure, the information element RACH-ConfigCommon can be adjusted to clarify which specific release is specified.

[0112] For example, the CBRA configuration in Release 17 can be distinguished from the CBRA configuration in legacy releases by a different suffix, such as RACH-ConfigCommon-r17.

[0113] For example, the CBRA configuration in Release 17 can be distinguished from the CBRA configuration in legacy releases by a different name, such as RACH-ConfigCommonExt-R17.

[0114] In one embodiment, the specified release includes at least one of a legacy release and Release 17. In one embodiment, the legacy release includes at least one of Release 15 and Release 16.

[0115] 8 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. 8, the step of instructing the terminal to determine random access occasion (RO) resource information of an initiated 4-step CFRA based on RO resource information of a 4-step CBRA of a designated release includes the following step S801:

[0116] In step S801, 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 of the RO resource information of the initiated 4-step CFRA.

[0117] In one embodiment, the manner of initiating the 4-step CFRA may include initiating by a PDCCH order, initiating by a system information request (SI request), and initiating by a handover command.

[0118] The RO configuration information and the correspondence relationship between SSB and RO mainly included in the RO resource information of the 4-step CBRA are the RO configuration information and the correspondence relationship between SSB and RO that the terminal needs to determine.

[0119] For the above three initiation methods, if the initiation method is initiated by a system information request (SI request) or by a handover command, the terminal must determine the RO configuration information and the correspondence between SSB and RO in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the specified release.

[0120] On the other hand, if the initiation method is initiation by PDCCH order, the network side device indicates information such as SSB index and PRACH mask index via PDCCH, and the terminal can determine the correspondence between SSB and RO based on this information. Therefore, the network side device can instruct the terminal to determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step CBRA of the specified release.

[0121] That is, for the above three initiation methods, the network side device needs to instruct the terminal to determine RO configuration information in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step contention random access (CBRA) of the specified release. For example, it can 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 4-step CFRA. On the other hand, if the initiation method is initiated by a system information request (SI request) or initiated by a handover command, the network side device needs to further instruct the terminal to determine a correspondence relationship between SSB and RO in the RO resource information of the initiated 4-step CFRA. The content of determining the correspondence relationship will be described in the following examples.

[0122] Furthermore, when the initiation method is initiation by PDCCH order, in this embodiment, the network side device does not indicate RO configuration information in the RO resource information of the CFRA, and the terminal may determine the RO configuration information of the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA.The network side device may indicate the RO configuration information in the RO resource information of the CFRA by downlink control information DCI (Downlink Control RO Information) in the PDCCH, and the terminal may determine the RO configuration information of the RO resource information of the initiated 4-step CFRA based on the RO configuration information indicated by the DCI.

[0123] 9 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. 9, the step of instructing the terminal to determine RO configuration information in the RO resource information of the 4-step CBRA of the designated release as RO configuration information in the RO resource information of the initiated 4-step CFRA includes the following step S901: In step S901, 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 4-step CFRA.

[0124] 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 4-step CFRA.

[0125] 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, the step of instructing the terminal to determine RO configuration information in the RO resource information of the 4-step CBRA of the designated release as RO configuration information in the RO resource information of the initiated 4-step CFRA includes the following step S1001:

[0126] In step S1001, 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 of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0127] In one embodiment, the specified release may be Release 17. Since different CBRA configuration information can be configured for different features in Release 17, the terminal can configure multiple 4-step CBRA RO resource information in Release 17.

[0128] 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 multiple 4-step CBRAs in Release 17 as the RO configuration information in the RO resource information of the initiated 4-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 4-step CFRA.

[0129] Here, the network side device instructs the terminal to determine RO configuration information in some resource information among multiple RO resource information of Rel. 17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA. The some resource information can be determined based on a predefined Rel. 17 4-step CBRA configuration information list. For example, multiple RO configuration information may be arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer equal to or greater than 1.

[0130] Furthermore, when the network side device instructs 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 4-step CFRA, it means that the RO configured by the RO configuration information in the total resource information is available to the terminal.

[0131] 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 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 4-step CFRA includes: The method includes a step of instructing the terminal to determine RO configuration information in some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0132] In an embodiment, when a network side device instructs a terminal to determine RO resource information of an initiated 4-step CFRA based on RO resource information of a Release-17 4-step CBRA, the terminal determines RO configuration information in some or all of the RO resource information of multiple Release-17 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0133] On the other hand, if the network side device does not instruct the terminal to determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of Release 17, the terminal can determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0134] 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 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 4-step CFRA includes: If the terminal supports determining RO configuration information in the RO resource information of the initiated 4-step CFRA based on RO configuration information in the RO resource information of the Release-17 4-step CBRA, the method includes 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 the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0135] The method comprises: If the terminal does not support determining RO resource information of the initiated 4-step CFRA based on RO resource information of the 4-step CBRA of Release 17, the method further includes instructing the terminal to determine RO configuration information in the RO resource information of the initiated 4-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0136] In an embodiment, the network side device may determine, based on the terminal's own capability, whether to instruct the terminal 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 4-step CFRA.

[0137] For example, if the network side device determines that the capability of the terminal supports determining the RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA in Release 17 (which may refer to the terminal supporting one or a combination of the above features introduced in R17), it can instruct the terminal to determine the RO configuration information in some or all 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.

[0138] On the other hand, if the network side device determines that the capability of 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, it may instruct the terminal to determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0139] In one embodiment, the terminal capabilities may include the terminal's support status for features such as Slicing, SDT, CE, and Redcap. The network side device can determine the features supported by the terminal from the features based on the terminal. Then, the network side device can determine one or more 4-step CBRA RO resource information corresponding to the features supported by the terminal from the RO resource information of multiple 4-step CBRAs in Release 17, and further instruct the terminal to set the determined one or more 4-step CBRA RO resource information as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0140] For example, the network side device configures the RO resource information of four Release-17 4-step CBRAs for the terminal for the four features, Slicing, SDT, CE, and Redcap, respectively. If the network side device determines based on the terminal's capabilities that the terminal supports only the two features, CE and Redcap, it can instruct the terminal to determine the RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four Release-17 4-step CBRAs, and to set the determined RO resource information of the two 4-step CBRAs as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0141] 11 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. 11, the step of instructing the terminal to determine RO configuration information in the RO resource information of the 4-step CBRA of the designated release as RO configuration information of the RO resource information of the initiated 4-step CFRA includes the following step S1101: In step S1101, the terminal is instructed to determine the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release and some or all of the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0142] In one embodiment, the specified release may include a legacy release and Release 17. Since different CBRA configuration information can be configured for different features in Release 17, the terminal can configure multiple 4-step CBRA RO resource information in Release 17.

[0143] In this case, the network side device may instruct the terminal to determine the RO configuration information in some (which may be one or more) of the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-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 4-step CFRA.

[0144] In this case, when the network side device instructs the terminal to determine RO configuration information in at least some resource information among multiple RO resource information of Rel.-17 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA, the some resource information may be determined based on a predefined Rel.-17 4-step CBRA configuration information list. For example, multiple RO configuration information may be arranged in order in the list, and the some resource information may be the first n configuration information in the list, where n is an integer equal to or greater than 1.

[0145] Furthermore, when the network side device instructs 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 4-step CFRA, it means that the RO configured by the RO configuration information in the total resource information is available to the terminal.

[0146] 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 4-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 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 4-step CFRA.

[0147] In one embodiment, 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 legacy release and some or all of the RO resource information of the multiple 4-step CBRAs of Release 17 as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0148] On the other hand, if the network side device does not instruct the terminal to determine the RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA of the legacy release and the RO resource information of the 4-step CBRA of Release 17, the terminal can determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0149] 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 4-step CFRA includes: If the terminal supports determining RO resource information of the initiated 4-step CFRA based on RO resource information of a 4-step CBRA of Release 17, the method includes a step of instructing the terminal to determine RO configuration information in the RO resource information of the 4-step CBRA of a legacy release and some or all of the RO resource information of multiple 4-step CBRAs of Release 17 as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0150] The method comprises: If the terminal does not support determining RO resource information of the initiated 4-step CFRA based on RO resource information of the 4-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 4-step CFRA based on RO configuration information in the RO resource information of the 4-step CBRA of a legacy release.

[0151] In one embodiment, the network side device can determine, based on the capability of the terminal, whether to instruct the terminal 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 4-step CFRA.

[0152] For example, if the network side device determines that the terminal supports determining the RO resource information of the initiated 4-step CFRA based on the RO resource information of the 4-step CBRA in Release 17 (which may refer to the terminal supporting one or a combination of the features introduced in R17), the network side device may instruct the terminal to determine the RO configuration information in the RO resource information of the 4-step CBRA in the legacy release and some or all 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.

[0153] On the other hand, if the network side device determines that the capability of 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, it may instruct the terminal to determine the RO configuration information in the RO resource information of the initiated 4-step CFRA based on the RO configuration information in the RO resource information of the 4-step CBRA of the legacy release.

[0154] In one embodiment, the terminal capabilities may further include the terminal's support status for features such as Slicing, SDT, CE, and Redcap. The terminal may determine features supported by its own capabilities from the features. When the terminal determines the RO resource information of the initiated 4-step CFRA based on at least the RO resource information of the Release-17 4-step CFRA, the terminal may determine the RO resource information of one or more 4-step CBRAs corresponding to the supported features from the RO resource information of multiple Release-17 4-step CBRAs, and may further determine the determined RO resource information of the one or more 4-step CBRAs as RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0155] For example, if a network side device configures the RO resource information of four Release-17 4-step CBRAs for a terminal for four features, namely, Slicing, SDT, CE, and Redcap, and the terminal's capability supports only two of the features, namely, CE and Redcap, the terminal can determine the RO resource information of two 4-step CBRAs corresponding to the CE and Redcap features from the RO resource information of the four Release-17 4-step CBRAs, and further 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 4-step CFRA.

[0156] 12 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. 12, the manner of initiating the four-step CFRA includes at least one of initiating by a system information request (SI request) and initiating by a handover command. The method further includes the following step S1201:

[0157] In step S1201, instruct the terminal to determine the correspondence relationship between SSB and RO in the RO resource information of the initiated 4-step CFRA according to a specified method.

[0158] In one embodiment, as can be seen from the above embodiment, for each of the above three initiation methods, the network side needs to instruct the terminal to determine RO configuration information in the RO resource information of the initiated 4-step CFRA based on the random access occasion (RO) resource information of the 4-step CBRA of the designated release. For example, the RO configuration information in the RO resource information of the 4-step CBRA of the designated release can be determined as the RO configuration information in the RO resource information of the initiated 4-step CFRA.

[0159] On the other hand, if the initiation method is initiated by a system information request (SI request) or by a handover command, the network side device needs to further instruct the terminal to determine a correspondence relationship between the SSB and the RO in the RO resource information of the initiated 4-step CFRA. Specifically, the network side device can instruct the terminal to determine a correspondence relationship between the SSB and the RO in the RO resource information of the initiated 4-step CFRA according to a specified method. Then, the terminal can determine an RO to be used for the initiated 4-step CFRA based on the RO configuration information and the correspondence relationship.

[0160] In one embodiment, the specified method is: Determine the correspondence between the synchronization signal block (SSB) and the RO in the RO resource information of the 4-step CBRA of the specified release as the correspondence between the SSB and the RO in the RO resource information of the initiated 4-step CFRA; and determining a correspondence relationship between synchronization signal blocks (SSBs) and ROs in the RO resource information of the initiated 4-step CFRA based on a correspondence relationship between SSBs and ROs in the RO resource information of the 4-step CBRA of all releases that is pre-configured in the terminal by a network side device (e.g., system information broadcast).

[0161] In one embodiment, after the UE determines 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 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 4-step CBRA of the designated release as the correspondence between the SSB and the RO in the RO resource information of the initiated 4-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.

[0162] In one embodiment, the terminal determines 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 based on the above-mentioned embodiment, and then can determine the correspondence relationship between the synchronization signal blocks (SSBs) and the ROs in the RO resource information of the initiated 4-step CFRA based on the correspondence relationship between the SSBs and the ROs in the RO resource information of the 4-step CBRA of all releases (not necessarily limited to the RO resource information of the 4-step CBRA of the specified release) pre-configured in the terminal by the network side device.

[0163] If there are multiple SSB-RO correspondence relationships in the RO resource information of the 4-step CBRA for all releases preconfigured in the terminal by the network-side device, the terminal can determine one SSB-RO correspondence relationship from among them. Here, the SSB-RO correspondence relationship is characterized by a value such as 1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, or 16, and the terminal can select one of the values, for example, the maximum or minimum value.
