Title:
WIRELESS COMMUNICATION DEVICE, COMMUNICATION METHOD, COMPUTER PROGRAM, AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/135027
Kind Code:
A1
Abstract:
[Problem] To provide a wireless communication device that, when transmitting/receiving data at a short transmission time interval shorter than an already-existing transmission time interval, allows data to be transmitted/received at a short transmission time interval length that is optimal for a terminal device from among a plurality of short transmission time interval lengths. [Solution] Provided is a wireless communication device comprising: a frame creation unit that creates a frame consisting of a plurality of subframes; a transmission unit that transmits the created frame to another communication device; and a notification unit that notifies information about a plurality of lengths of short transmission time intervals within the subframe, said short transmission time intervals being transmission time intervals shorter than a single subframe period.
