Patent ID: 11962446
Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A terminal, comprising:
a processor;
a transceiver connected to the processor; and
a memory configured to store instructions executable by the processor;
wherein, the processor is configured to:
receive a pattern identifier configured by an access network device, wherein the pattern identifier configures a first physical resource configuration pattern of the physical random access channel corresponding to a first subcarrier spacing in a frequency domain;
determine a second subcarrier spacing of a target cell; and
determine a second physical resource configuration pattern of the physical random access channel corresponding to the second subcarrier spacing in the frequency domain according to the pattern identifier and the second subcarrier spacing;
wherein the processor is further configured to:
determine a first frequency domain parameter corresponding to the first physical resource configuration pattern and the first subcarrier spacing according to the pattern identifier; and
obtain a second frequency domain parameter corresponding to the second physical resource configuration pattern by converting the first frequency domain parameter corresponding to the first physical resource configuration pattern according to a relationship between the first subcarrier spacing and the second subcarrier spacing; wherein the first frequency domain parameter comprises a number of repetitions of a physical random access channel sequence sent in the first physical resource configuration pattern; the second frequency domain parameter comprises a number of repetitions of a physical random access channel sequence sent in the second physical resource configuration pattern.
