Wireless communication device, wireless communication system, and wireless communication method

Abstract

If a wireless communication device used in this wireless communication system is a wireless relay terminal (201), the wireless communication device is provided with a timing information analysis unit (26) that analyzes timing information for intermittently received signals included in wireless signals, and relays the wireless signals in sync with the intermittent waiting for received signals in a wireless child terminal (301). If the wireless communication device is a wireless child terminal (301), the wireless communication system is provided with a timing information transmission unit (24) that creates intermittent reception timing information specifying the timing (intermittent reception timing) for intermittently waiting for received signals, and transmits the intermittent reception timing information to a wireless parent terminal (101) via the wireless relay terminal (201). Thus, increases in power consumption can be minimized with a simple configuration, and various types of communication can be carried out between a wireless parent terminal (101) and a wireless child terminal (301), even via a wireless relay terminal (201), at suitable times, in sync with the intermittent reception timing of the wireless child terminal (301).

Description

technical field [0001] The present invention relates to a wireless communication system composed of at least a master wireless terminal and a slave wireless terminal, preferably including a relay wireless terminal, suitably used as one of the master wireless terminal, slave wireless terminal, and relay wireless terminal A wireless communication device and a wireless communication method suitably used for such a wireless communication device. Background technique [0002] In the technical field of a wireless communication system including a master wireless terminal and a slave wireless terminal, there is conventionally known a configuration in which each of these wireless terminals intermittently waits for reception in an asynchronous manner without synchronizing their respective clocks. In such a wireless communication system, since it is not known at what timing the communication partner (for example, the master wireless terminal from the perspective of the slave wireless t...
