In a communication system, a network device can provide multiple different random access resource configurations for user equipment (UE) to perform different random access control on the UE. However, due to the fact that some resource configuration contents in different random access resource configurations may be the same or missing, it is necessary to determine a usage rule of the random access configurations when the UE triggers different random access processes.
A detailed description is made to a method, a device, user equipment (UE), a network device, and a storage medium for determining a random access resource configuration provided in this disclosure in the following, with reference to the accompanying drawings.
Step 101, a usage rule for random access resource configurations is determined in response to the UE triggering a random access process.
In an embodiment of the disclosure, the UE may be a device that provides voice and/or data connectivity to a user. The UE may communicate with one or more core networks through a Radio Access Network (RAN). The UE may be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or a “cellular” phone), and a computer having an IoT terminal. For example, the UE may be a fixed, portable, pocket, handheld, computer built-in, or vehicle mounted device, such as a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal or a user agent. Or, the UE may be a device for an unmanned aerial vehicle. Or, the UE may be a vehicle-mounted device, such as a driving computer with a wireless communication function or a wireless terminal externally connected to a driving computer. Or, the UE may be a roadside device, such as a street light, a signal light, or other roadside devices with a wireless communication function.
In an embodiment of the disclosure, the usage rule may be used to determine a random access resource configuration used in a random access process. In an embodiment of the disclosure, the determined usage rule may vary depending on the random access process triggered by the UE.
In an embodiment of the disclosure, when the UE triggers a contention-free random access process, a first usage rule is determined. The first usage rule is used to determine a random access resource configuration in the contention-free random access process.
In another embodiment of the disclosure, when the UE triggers a contention-based random access process, a second usage rule is determined. The second usage rule is used to determine a random access resource configuration in a contention-based random access process.
In an embodiment of the disclosure, the method for the UE to determine the usage rule for random access resource configurations may include at least one of:
Step 102, a random access resource configuration is determined based on the usage rule, and random access is performed based on the random access resource configuration.
In an embodiment of the disclosure, the random access process triggered by UE may be a contention-free random access process, and the first usage rule may be used to determine the random access resource configuration. In another embodiment of the disclosure, the random access process triggered by UE may be a contention-based random access process, and the second usage rule may be used to determine the random access resource configuration.
A detailed introduction of the first usage rule and second usage rule may refer to following embodiments.
In summary, in the method for determining a random access resource configuration provided in the embodiments of the disclosure, in response to the UE triggering the random access process, the UE may determine the usage rule for random access resource configurations, determine the random access resource configuration based on the usage rule, and perform the random access based on the determined random access resource configuration. In this way, in embodiments of the disclosure, the UE may determine a specific random access resource configuration based on the usage rule when triggering different random access processes, and may ensure that a network device and the UE maintain consistent in random access resource configuration based on the usage rule, thereby improving the stability of the random access process.
Step 201, a first random access resource configuration and/or a second random access resource configuration sent by a network device is obtained.
In an embodiment of the disclosure, the first random access resource configuration and the second random access resource configuration each includes at least one random access resource configuration.
In an embodiment of the disclosure, the first random access resource configuration may be a random access resource configuration corresponding to a first version, and the second random access resource configuration mentioned may be a random access resource configuration corresponding to a second version. The first version predates the second version. For example, in an embodiment of the disclosure, the first version may be Release-15 version and/or Release-16 version. The second version may be Release-17 version.
In an embodiment of the disclosure, the first random access resource configuration may include at least one of:
In an embodiment of the disclosure, the contention-based random access resource configuration may include at least one of a contention-based two-step random access resource configuration, or a contention-based four-step random access resource configuration. The contention-free random access resource configuration may include at least one of a contention-free two-step random access resource configuration, or a contention-free four-step random access resource configuration.
In an embodiment of the disclosure, in case that the first version is Release-15, the first random access resource configuration may include a contention-based four-step random access resource configuration (such as Rel-15 RACH ConfigCommon), a contention-free 4-step random access resource configuration (Rel-15 RACH ConfigDedicated (for a switching process), or Rel-15 BeamFailureRecoveryConfiguration (for a recovery process for a beam failure).
In another embodiment of the disclosure, in case that the first version is Release-16, the first random access resource configuration may include a contention-based two-step random access resource configuration (such as Rel-16 RACH ConfigCommonTwoStepRA) and a contention-free two-step random access resource configuration (Rel-16 RACH ConfigGenericTwoStepRA).
In an embodiment of the disclosure, each random access resource configuration in the second random access resource configuration corresponds to one specific function.
In an embodiment of the disclosure, the specific function may include at least one of:
In an embodiment of the disclosure, the second random access resource configuration may include a contention-based random access resource configuration.
In an embodiment of the disclosure, the contention-based random access resource configuration in the second random access resource configuration may include at least one of:
Step 202, a usage rule for random access resource configurations is determined in response to the UE triggering a random access process.
Step 203, a random access resource configuration is determined based on the usage rule from the first random access resource configuration and/or the second random access resource configuration, and random access is performed based on the random access resource configuration.
In an embodiment of the disclosure, the detailed introduction of steps 202-203 may refer to the relevant introduction in the above embodiments, which is not elaborated in embodiments of the disclosure.
In summary, in the method for determining a random access resource configuration provided in the embodiments of the disclosure, in response to the UE triggering the random access process, the UE may determine the usage rule for random access resource configurations, determine the random access resource configuration based on the determined usage rule, and perform the random access based on the determined random access resource configuration. In this way, in embodiments of the disclosure, the UE may determine a specific random access resource configuration based on the usage rule when triggering different random access processes, and may ensure that a network device and the UE maintain consistent in random access resource configuration based on the usage rule, thereby improving the stability of the random access process.
Step 301, a first random access resource configuration and/or a second random access resource configuration sent by a network device is obtained.
In an embodiment of the disclosure, the detailed introduction of the first random access resource configuration and the second random access resource configuration may refer to the relevant introduction in the above embodiments, which is not elaborated in embodiments of the disclosure.
Step 302, a first usage rule for random access resource configurations is determined in response to the UE triggering a contention-free random access process.
In an embodiment of the disclosure, the first usage rule may include at least one of:
Step 303, a random access resource configuration is determined based on the first usage rule from the first random access resource configuration and/or the second random access resource configuration, and random access is performed based on the determined random access resource configuration.
With reference to the step 302 above, it can be seen that the first usage rule includes multiple different rules. Therefore, in an embodiment of the disclosure, the method for determining the random access resource configuration based on the first usage rule in step 303 may vary with the first usage rule determined in step 302.
In an embodiment of the disclosure, when the first usage rule determined in above step 302 is rule 1, the method for determining the random access resource configuration based on rule 1 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration from the contention-free random access resource configuration in the first random access resource configuration.
For example, in an embodiment of the disclosure, the UE may determine the random access resource configuration based on a Random Access Channel RO Occupation (RACH Occupation, RO) resource indicated in Rel-15 RACH ConfigDedicated and a preamble identifier.
In another embodiment of the disclosure, when the first usage rule determined in above step 302 is rule 2, the method for determining the random access resource configuration based on rule 2 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration from the contention-free random access resource configuration in the first random access resource configuration, and/or at least a portion of the contention-based random access resource configuration in the first random access resource configuration.
For example, in an embodiment of the disclosure, in case that the RACH ConfigDedicated does not include an RO resource (i.e., the contention-free random access resource configuration in the first random access resource configuration does not include an RO resource), but includes a preamble identification and a Reference Signal Received Power (RSRP) configuration for beam selection (e.g, RSRP corresponds to a Synchronous Signal Block (SSB) or a Channel State Information Reference Signal (CSI-RS)), the UE may determine an RO resource indicated in Rel-15 RACH ConfigCommon (i.e. the portion of the contention-based random access resource configuration in the first random access resource configuration) and the preamble identifier indicated in RACH ConfigDedicated (i.e. the contention-free random access resource configuration in the first random access resource configuration) as the random access resource configuration.
For example, in another embodiment of the disclosure, in case that the RACH ConfigDedicated does not include an RO resource or an RSRP configuration for beam selection, but includes a preamble indication, the UE may determine an RO resource in Rel-15 RACH ConfigCommon and an RSRP configuration for beam selection in Rel-15 RACH ConfigCommon (i.e. all contention-based random access resource configurations in the first random access resource configuration), as well as a preamble identifier indicated in RACH ConfigDedicated (i.e. the contention-free random access resource configuration in the first random access resource configuration) as the random access resource configuration.
In another embodiment of the disclosure, when the first usage rule determined in above step 302 is rule 3, the method for determining the random access resource configuration based on rule 3 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration from all random access resource configurations in the first random access resource configuration, and/or from all random access resource configurations in the second random access resource configuration.
For example, in an embodiment of the disclosure, in case that RACH ConfigDedicated indicates an RO resource, a preamble indication, an RSRP configuration used for beam selection, Rel-15 RACH ConfigCommon indicates an RO resource and an RSRP configuration for beam selection, and Rel-17 featureCombinationRACH ConfigCommon indicates an RO resource and an RSRP configuration for beam selection, the UE may determine the RO indicated in RACH ConfigDedicated, the RO indicated in Rel-15 RACH ConfigCommon, and the RO indicated in Rel-17 featureCombinationRACH ConfigCommon (i.e., the random access resource configurations in the second random access resource configuration) as RO resources of the random access resource configuration.
In another embodiment of the disclosure, when the first usage rule determined in above step 302 is rule 4, the method for determining the random access resource configuration based on rule 4 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration from at least one of: the contention-free random access resource configuration in the first random access resource configuration, at least a portion of the contention-based random access resource configuration in the first random access resource configuration, and a random access resource configuration corresponding to the first specific function in the second random access resource configuration.
In an embodiment of the disclosure, the first specific function may include at least one of:
For example, in an embodiment of the disclosure, in case that the UE supports the RedCap function and the SDT function in the specific function, it may be determined that the first specific function is the RedCap function and the SDT function. In this case, the random access resource configuration may be determined from at least one of: the contention-free random access resource configuration in the first random access resource configuration, at least a portion of the contention-based random access resource configuration in the first random access resource configuration, or random access resource configurations corresponding to the RedCap function and the SDT function in the second random access resource configuration.
In another embodiment of the disclosure, when the first usage rule determined in above step 302 is rule 5, the method for determining the random access resource configuration based on rule 5 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration from at least one of: the contention-free random access resource configuration in the first random access resource configuration, or the random access resource configuration corresponding to the first specific function in the second random access resource configuration.
The introduction of the first specific function may refer to the relevant introduction for rule 4 above.
In summary, in the method for determining a random access resource configuration provided in the embodiments of the disclosure, in response to the UE triggering the random access process, the UE may determine the usage rule for random access resource configurations, determine the random access resource configuration based on the determined usage rule, and perform the random access based on the determined random access resource configuration. In this way, in embodiments of the disclosure, the UE may determine a specific random access resource configuration based on the usage rule when triggering different random access processes, and may ensure that a network device and the UE maintain consistent in random access resource configuration based on the usage rule, thereby improving the stability of the random access process.
Step 401, a first random access resource configuration and/or a second random access resource configuration sent by a network device is obtained.
In an embodiment of the disclosure, the detailed introduction of the first random access resource configuration and the second random access resource configuration may refer to the relevant introduction in the above embodiments, which is not elaborated in embodiments of the disclosure.
Step 402, a second usage rule for random access resource configurations is determined in response to the UE triggering a contention-based random access process.
In an embodiment of the disclosure, the second usage rule may include at least one of:
Step 403, a random access resource configuration is determined based on the second usage rule from the first random access resource configuration and/or the second random access resource configuration, and random access is performed based on the determined random access resource configuration.
With reference to the step 402 above, it can be seen that the second usage rule includes multiple different rules. Therefore, in an embodiment of the disclosure, the method for determining the random access resource configuration based on the second usage rule in step 403 may vary with the first usage rule determined in step 402.
In an embodiment of the disclosure, when the second usage rule determined in above step 402 is rule 6, the method for determining the random access resource configuration based on rule 6 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration based on all random access resource configurations in the first random access resource configuration.
For example, in an embodiment of the disclosure, in case that the network device is configured with Rel-15 RACH ConfigCommon and also with Rel-17 featureCombinationRACH ConfigCommon, the UE may determine Rel-15 RACH ConfigCommon as the random access resource configuration in response to the contention-based random access process being triggered by a function other than the specific function.
In another embodiment of the disclosure, when the second usage rule determined in above step 402 is rule 7, the method for determining the random access resource configuration based on rule 7 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration based on all random access resource configurations in the first random access resource configuration, and/or the random access resource configuration corresponding to the first specific function in the second random access resource configuration.
For example, in an embodiment of the disclosure, in case that the first specific function is a specific function supported by the UE, and the UE supports the RedCap function and SDT function in the specific function, the UE may support any combination of the RedCap function and the SDT function. In response to the contention-based random access process being triggered by a function other than the specific function, the random access resource configuration may be determined based on all random access resource configurations in the first random access resource configuration, and/or the random access resource configurations corresponding to the RedCap function and SDT function in the second random access resource configuration.
In another embodiment of the disclosure, when the second usage rule determined in above step 402 is rule 8, the method for determining the random access resource configuration based on rule 8 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration based on the random access resource configuration corresponding to the second specific function in the second random access resource configuration.
For example, in an embodiment of the disclosure, in case that the network device is configured with Rel-15 RACH ConfigCommon and Rel-17 featureCombinationRACH ConfigCommon corresponding to the second specific function. When the UE triggers the contention-based random access process (e.g. triggering a contention-based random access process of a SDT process of slice-1) by the second specific function, the UE determines Rel-17 featureCombinationRACH ConfigCommon as the random access resource configuration.
In another embodiment of the disclosure, when the second usage rule determined in above step 402 is rule 9, the method for determining the random access resource configuration based on rule 9 from the first random access resource configuration and/or the second random access resource configuration may include: determining the random access resource configuration based on the random access resource configuration corresponding to the second specific function in the second random access resource configuration, and/or at least a portion of random access resource configurations in the first random access resource configuration.
For example, in an embodiment of the disclosure, in case that the network device is configured with Rel-15 RACH ConfigCommon and Rel-17 featureCombinationRACH ConfigCommon corresponding to the second specific function, and there is a RSRP configuration for beam selection but no RO configuration in Rel-17 featureCombinationRACH ConfigCommon, when the UE triggers the contention-based random access process by the second specific function (e.g, when the UE triggers the contention-based random access process by the SDT process of slice-1, i.e., the second specific function is a combination of the slicing function and the SDT function), the UE may determine the RSRP configuration for beam selection in Rel-17 featureCombinationRACH ConfigCommon corresponding to the second specific function, as well as the RO configuration in Rel-15 RACH ConfigCommon (i.e. the portion of random access resource configurations in the first random access resource configuration) as the random access resource configuration.
For example, in another embodiment of the disclosure, in case that the network device is configured with Rel-15 RACH ConfigCommon and Rel-17 featureCombinationRACH ConfigCommon corresponding to the second specific function, and there is no RO configuration or RSRP configuration for beam selection in Rel-17 featureCombinationRACH ConfigCommon, when the UE triggers the contention-based random access process by the second specific function (e.g., triggering the contention-based random access process of the SDT process of slice-1, i.e., the second specific function is a combination of the slicing function and the SDT function), the UE determines the RSRP configuration for beam selection in Rel-15 RACH ConfigCommon, as well as the RO configuration in Rel-15 RACH ConfigCommon (i.e. all random access resource configurations in the first random access resource configuration) as the random access resource configuration.
For example, in another embodiment of the disclosure, in case that the network device is configured with Rel-15 RACH ConfigCommon and Rel-17 featureCombinationRACH ConfigCommon corresponding to the second specific function, and there is an RO configuration but no RSRP configuration for beam selection in the configuration of Rel-17 featureCombinationRACH ConfigCommon, when the UE triggers the contention-based random access process by the second specific function (e.g. triggering the contention-based random access process of the SDT process of slice-1, i.e. the second specific function is a combination of the slicing function and the SDT function), the UE may determine the RSRP configuration for beam selection in Rel-15 RACH ConfigCommon, the RO configuration in Rel-15 RACH ConfigCommon (i.e. all random access resource configurations in the first random access resource configuration), and the RO configuration in Rel-17 featureCombinationRACH ConfigCommon as the random access resource configuration.
The introduction of the first and second specific function may refer to the relevant introduction for rule 4 above.
