Communication device, communication method, communication system, and base system

摘要

A communication device, system and method cooperate to transmit a signal from a base station, where the signal includes a current frame and a target frame. A counting unit counts a frame period and a reception control unit causes the receiving unit to transition to a sleep state. A reception control unit causes the receiving unit to return from the sleep state before a counting result of the counting unit reaches the target frame. The reception control unit also causes the receiving unit to return to the sleep state over a time period based on a difference between a current frame and the target frame.

1. A communication device comprising:
a receiver configured to receive a signal from a base station; circuitry configured to
count a frame period; andcause the receiver to transition from a sleep state before a counting result of the circuitry reaches a target frame;identify a system frame number of a current frame; andcause the receiver to transition to the sleep state over a time period based on a difference between the system frame number of the current frame and a system frame number of the target frame.
