Abstract
This application provides a preamble sequence configuration method, user equipment, and an access network device. The method in embodiments of this application includes: determining, by an access network device, preamble sequence information, where the preamble sequence information includes a message indicating a quantity of preamble sequences; and sending, by the access network device, the preamble sequence information to user equipment, where the preamble sequence information is used by the user equipment for random access.
Claims18
A preamble sequence configuration method, comprising:
- determining, by an access network device, preamble sequence information, wherein the preamble sequence information comprises a message indicating a quantity of preamble sequences, the preamble sequences are across a time domain, a frequency domain, and a code domain in a preamble sequence space, and the preamble sequence space further comprises a plurality of layers of code domain space in the code domain, and
- wherein determining the preamble sequence information comprises determining space level information that indicates a quantity of code domain space layers of the preamble sequence space;
- including, by the access network device, the space level information in the preamble sequence information;
- and
- sending, by the access network device, the preamble sequence information to user equipment, wherein the preamble sequence information comprises the space level information and is used by the user equipment for random access.
A preamble sequence configuration method, comprising:
- obtaining, by user equipment, preamble sequence information sent by an access network device, wherein the preamble sequence information comprises a message indicating a quantity of preamble sequences, the preamble sequences are across a time domain, a frequency domain, and a code domain in a preamble sequence space, and the preamble sequence space further comprises a plurality of layers of code domain space in the code domain, and wherein the preamble sequence information comprises space level information that indicates a quantity of code domain space layers of the preamble sequence space;
- obtaining, by the user equipment, the space level information in the preamble sequence information;
- and
- performing, by the user equipment, random access based on the preamble sequence information.
User equipment, comprising:
- a receiver;
- at least one processor coupled to the receiver;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor;
- wherein the receiver is configured to obtain preamble sequence information sent by an access network device, wherein the preamble sequence information comprises a message indicating a quantity of preamble sequences, the preamble sequences are across a time domain, a frequency domain, and a code domain in a preamble sequence space, and the preamble sequence space further comprises a plurality of layers of code domain space in the code domain, and wherein the preamble sequence information comprises space level information that indicates a quantity of code domain space layers of the preamble sequence space;
- wherein the receiver is configured to further obtain the space level information in the preamble sequence information;
- and
- wherein the programming instructions instruct the at least one processor to perform random access based on the preamble sequence information.
