Patent ID: 11950228
Assignee: SHARP KABUSHIKI KAISHA
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A terminal device comprising:
reception circuitry configured to:
receive a first signal for first synchronization with a first subcarrier spacing,
receive a second signal for the first synchronization with the first subcarrier spacing,
receive a third signal for second synchronization with a second subcarrier spacing, the first subcarrier spacing and the second subcarrier spacing being used individually among a plurality of different subcarrier spacing candidates, and
receive a fourth signal, with a third subcarrier spacing, neither for the first synchronization nor for the second synchronization, the third subcarrier spacing being different from the second subcarrier spacing;

detection circuitry configured to detect a physical cell identity based on the first signal and the second signal; and
synchronization circuitry configured to perform the first synchronization for a cell based on the first signal and the second signal and perform the second synchronization for the cell based on the third signal, wherein:
the first signal is a primary synchronization signal,
the second signal is a secondary synchronization signal,
the third signal is a Non-Zero Power-Channel State Information-Reference signal, and
the fourth signal is a Non-Zero Power-Channel State Information-Reference signal.
