COMMUNICATION DEVICE, METHOD AND COMMUNICATION SYSTEM

摘要

A communication device includes a receiving circuit and a start-up time adjustment circuit configured to transmit, to the receiving circuit, a start signal that instructs a change from a sleep state to an active state, wherein the start-up time adjustment circuit is configured to transmit, to the receiving circuit, a first start signal that instructs a change from the sleep state to the active state at a first time earlier than a second time when a first signal reaches the communication device, measure a first time difference between the second time and the first time, determine, based on the first time difference, a third time when the receiving circuit is changed from the active state to the sleep state, and transmit a second start signal that instructs a change from the sleep state to the active state to the receiving circuit at the third time.

1. A communication device which receives a plurality of signals transmitted at time intervals, the communication device comprising:
a receiving circuit configured to receive the plurality of signals; and a start-up time adjustment circuit configured to transmit, to the receiving circuit, a start signal that instructs a change from a sleep state to an active state, wherein
the start-up time adjustment circuit is configured totransmit, to the receiving circuit, a first start signal that instructs a change from the sleep state to the active state at a first time earlier than a second time when a first signal among the plurality of signals reaches the communication device,measure a first time difference between the second time and the first time,determine, based on the first time difference, a third time that is a time after a time when the receiving circuit is changed from the active state to the sleep state, andtransmit a second start signal that instructs a change from the sleep state to the active state to the receiving circuit at the third time.
