Communication System
Abstract: Provided is a communication system that can reduce latency while preventing reduction in a transmission rate. An eNB communicates with a UE #1 using a self-contained subframe including a first downlink signal (DL #1) and a first uplink signal (UL #1), and with a UE #2 using a self-contained subframe including a second downlink signal (DL #2) and a second uplink signal (UL #2). The self-contained subframe for the UE #1 includes a first gap duration (Gap #1) during which neither the DL #1 nor the UL #1 is transmitted, between transmission durations of the DL #1 and the UL #1. The self-contained subframe for the UE #2 includes a second gap duration (Gap #2) during which neither the DL #2 nor the UL #2 is transmitted, between transmission durations of the DL #2 and the UL #2. The Gaps #1 and #2 are set to each UE. [Figure: 8]

Specification
We Claim:
1. A communication system comprising a base station device and a plurality of communication terminal devices capable of radio communication with the base station device,
wherein the base station device communicates with each of the plurality of communication terminal devices using a self-contained subframe, the self-contained subframe including a downlink signal transmitted from the base station device to the communication terminal device, and an uplink signal transmitted from the communication terminal device to the base station device in response to the downlink signal,
the self-contained subframe includes a gap duration during which neither the downlink signal nor the uplink signal is transmitted, between a downlink transmission duration during which the downlink signal is transmitted and an uplink transmission duration during which the uplink signal is transmitted, and
the gap duration is set to each of the plurality of communication terminal devices.
2. The communication system according to claim 1,
wherein the self-contained subframe includes, in a frequency axis direction, a free space in which neither the downlink signal nor the uplink signal is transmitted, between a frequency domain in which the downlink signal is transmitted and a frequency domain in which the uplink signal is transmitted when the uplink transmission duration and the downlink transmission duration have an overlapping duration in communication with the different user equipment device.
