Abstract
Example random access methods and apparatuses are provided. One example method includes: receiving SUL configuration information, where the SUL configuration information includes at least one first SUL resource and at least one SUL selection threshold that are corresponding to a first SSB; determining, based on a downlink measurement value of the first SSB and the at least one SUL selection threshold, a carrier resource used for random access, where the carrier resource includes one of the at least one first SUL resource or includes a non-SUL resource corresponding to the first SSB; and performing random access on the determined carrier resource.
Claims12
A method, comprising:
- sending supplementary uplink (SUL) configuration information, wherein the SUL configuration information comprises N first SUL resources and at least one SUL selection threshold that are corresponding to a first synchronization signal block (SSB), wherein N is an integer greater than or equal to 2, wherein the SUL configuration information is used to determine a carrier resource used for random access, wherein the SUL configuration information comprises access priority information, wherein the access priority information is used to determine a second SUL resource from the N first SUL resources, wherein the access priority information indicates an access priority order of the N first SUL resources, wherein an access priority of the second SUL resource is higher than a priority of a SUL resource of the N first SUL resources other than the second SUL resource, and wherein the carrier resource comprises the second SUL resource or comprises a non-SUL resource corresponding to the first SSB;
- and
- receiving a random access preamble on the determined carrier resource.
An apparatus, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to perform operations comprising:
- receiving supplementary uplink (SUL) configuration information, wherein the SUL configuration information comprises N first SUL resources and at least one SUL selection threshold that are corresponding to a first SSB, wherein N is an integer greater than or equal to 2;
- determining a second SUL resource from the N first SUL resources based on access priority information, wherein the access priority information indicates an access priority order of the N first SUL resources, and wherein an access priority of the second SUL resource is higher than a priority of a SUL resource of the N first SUL resources other than the second SUL resource;
- determining, based on a downlink measurement value of the first SSB and the at least one SUL selection threshold, a carrier resource used for random access, wherein the carrier resource comprises the second SUL resource or comprises a non-SUL resource corresponding to the first SSB;
- and
- performing random access on the determined carrier resource.

- and
- a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to perform operations comprising:
- sending supplementary uplink (SUL) configuration information, wherein the SUL configuration information comprises N first SUL resources and N SUL selection thresholds that are corresponding to a first SSB, wherein N is an integer greater than or equal to 2, wherein the SUL configuration information is used to determine a carrier resource used for random access, wherein one of the N first SUL resources is corresponding to one of the N SUL selection thresholds, wherein the carrier resource comprises one of the N first SUL resources or comprises a non-SUL resource corresponding to the first SSB, and wherein:
- when a downlink measurement value of the first SSB is less than a SUL selection threshold corresponding to a second SUL resource and is greater than or equal to a SUL selection threshold corresponding to a third SUL resource, the carrier resource used for random access comprises the second SUL resource, wherein the second SUL resource and the third SUL resource are comprised in the N first SUL resources;
- when the downlink measurement value of the first SSB is less than an SUL selection threshold corresponding to a fourth SUL resource, the carrier resource used for random access comprises the fourth SUL resource, wherein the SUL selection threshold corresponding to the fourth SUL resource is a smallest value of the N SUL selection thresholds;
- or
- when the downlink measurement value of the first SSB is greater than or equal to a SUL selection threshold corresponding to a fifth SUL resource, the carrier resource used for random access comprises the non-SUL resource, wherein the SUL selection threshold corresponding to the fifth SUL resource is a largest value of the N SUL selection thresholds;
- and
- receiving a random access preamble on the determined carrier resource.
