[0039] At S21, first configuration information of a network device is received, where the first configuration information indicates at least one contention-based random access (CBRA) configuration in a first release.

[0040] In an embodiment of the present disclosure, the CBRA configuration of the first release includes a 4-step CBRA configuration of the first release and / or a 2-step CBRA configuration of the first release, and the first release is Release 17.

[0042] In an embodiment of the present disclosure, the network device transmits the first configuration information by broadcasting a system message, where the system message may be a system message SIB (System Information Block) x, where x is a positive integer, and the SIB x may be an existing system message or a newly defined system message. For example, in one embodiment of the present disclosure, the SIB x may be an existing SIB 1.

[0043] In some embodiments, the CBRA configuration of the first release is a common CBRA configuration of multiple different characteristics or combinations of characteristics of the first release, or a specific CBRA configuration of multiple different characteristics or combinations of characteristics of the first release, where the common CBRA configuration includes at least a target shared RO resource configuration and / or a target available RO set configuration.

[0044] In some embodiments, in response to the CBRA configuration of the first release being a particular CBRA configuration of a plurality of different characteristics or combinations of characteristics of the first release, the target available RO set of the CBRA configuration of the first release is adapted to at least one characteristic or combination of characteristics.

[0045] In S22, a target usable random access channel occasion (RO) set is determined based on the first configuration information, and / or a target shared RO resource is determined based on the first configuration information, and / or a target preamble set is determined based on the first configuration information.

[0046] In an embodiment of the present disclosure, a terminal can determine a target usable RO (RACH occasion, random access channel occasion) set based on the first configuration information, can also determine a target shared RO resource based on the first configuration information, and can also determine a target preamble set based on the first configuration information.

[0047] By implementing the embodiments of the present disclosure, a terminal receives first configuration information of a network device, where the first configuration information indicates at least one contention-based random access (CBRA) configuration in a first release, determines a target usable random access channel occasion (RO) set based on the first configuration information, and / or determines target shared RO resources based on the first configuration information, and / or determines a target preamble set based on the first configuration information, so that the terminal can determine the target usable RO set, the target shared RO resources, or the target preamble set and communicate with the network device on the determined resources.

[0048] Please refer to FIG. 3, which is a flowchart of another resource determination method provided by an embodiment of the present disclosure.

[0049] As shown in FIG. 3, the method is performed by a terminal, and the method may include, but is not limited to, step S31 and step S32.

[0050] At S31, first configuration information of a network device is received, where the first configuration information indicates at least one contention-based random access (CBRA) configuration in a first release.

[0051] For the description of S31 in the embodiment of the present disclosure, please refer to the description of S21 in the above embodiment, and detailed description will be omitted here.

[0052] In S32, a target usable RO set is determined based on the first configuration information, and the first usable RO set set in the CBRA configuration of the first release is determined as the target usable RO set.

[0053] It should be understood that if the terminal determines that the first usable RO set is configured in the first release CBRA configuration, the terminal can directly determine the target usable RO set based on the first release CBRA configuration.

[0054] It should be noted that S31 and S32 may be performed separately or together with any other steps in the embodiments of the present disclosure, for example, together with S21 and S22 in the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto.

[0063] In some embodiments, the terminal receives second configuration information of the network device, and determines a target usable RO set based on the second configuration information. In response to the second configuration information not indicating the first shared RO resource, the terminal determines the multiplexed second usable RO set as the target usable RO set.

[0064] In an embodiment of the present disclosure, the first shared RO resource configured by the network device may be a mapping relationship between the shared RO resource configured by the network device and a characteristic feature, so that the terminal can determine the first shared RO resource based on the mapping relationship between the shared RO resource and the characteristic feature.

[0068] As an example, in one embodiment of the present disclosure, the SIB x may be an existing SIB 1.

[0069] In some embodiments, the second configuration information and the first configuration information both correspond to a first release CBRA configuration.

[0070] It should be noted that S41 and S42 may be performed separately or together with any other steps in the embodiments of the present disclosure, for example, together with S21 and S22 and / or S31 and S32 in the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto.

[0076] In an embodiment of the present disclosure, the CBRA configuration of the first release is a common CBRA configuration of multiple different characteristics or combinations of characteristics of the first release, or a specific CBRA configuration of multiple different characteristics or combinations of characteristics of the first release, where the common CBRA configuration includes at least a target shared RO resource configuration and / or a target available RO set configuration.

[0077] In some embodiments, the CBRA configuration of the first release is a common CBRA configuration, and determines a target available RO set corresponding to the characteristic or characteristic combination based on a third available RO set corresponding to the characteristic or characteristic combination.
