Abstract

A wireless communication device includes a history holder configured to obtain notified timings of transmission requests when the transmission requests are notified, calculates request intervals of notifications of the transmission requests, and holds the request intervals at past n (n is an integer equal to or larger than 2) times; a timing controller configured to determine a transmission interval to the next packet transmission based on the request intervals; a transmitting/receiving unit configured to generate a packet which has time information indicating the transmission interval added to a header part of transmission data, transmits the packet to the other-party wireless communication device, and receives a packet from the other-party wireless communication device; and a communication controller configured to cause at least the transmitting/receiving unit to suspend operation during a period from when the packet is transmitted to when time of the transmission interval elapses.

Claims7

Dependent claims

A wireless communication device for transmitting a packet according to a transmission request notified from an application layer, the wireless communication device comprising:

a history holder configured to obtain notified timings of transmission requests if the transmission requests are notified, calculate request intervals of notifications of the transmission requests, and hold the request intervals at past n (n is an integer equal to or larger than 2) times in ascending order;
a timing controller configured to determine a transmission interval to a next packet transmission based on the request intervals;
a transmitting/receiving unit configured to generate a packet which includes time information indicating the transmission interval in a header part of transmission data, transmit the packet to another party wireless communication device, and receive a packet from the other-party wireless communication device;
and
a communication controller configured to cause at least the transmitting/receiving unit to suspend operation during a period from when the packet is transmitted to when time of the transmission interval elapses, wherein
the timing controller determines, as the transmission interval, an m-th (m is an integer equal to or smaller than n) value of the past n transmission request intervals held in the history holder in ascending order, and sets m to a value closer to 1 if a request to shorten time from when the transmission request is notified to when the packet transmission is started is notified from the application layer, and sets m to a value closer to n if a request to reduce power consumption is notified from the application layer.
