A radio communication device includes: a communication circuit configured to transmit and receive a signal to and from first radio communication device; and a control circuit configured to cause the communication circuit to receive a first signal in a first layer, the first signal being configured to include data in a second layer different from the first layer, and cause the communication circuit to transmit, through a first radio resource on a shared channel, acknowledgement information when the first signal from the first radio communication device is received, the first radio resource being selected from among the shared channel without scheduling information from the first communication device, the acknowledge information indicating whether the data in the second layer is normally received from the first radio communication device.
A radio communication device comprising:
A radio communication system comprising:
A radio communication method in a radio communication system including a first communication device and second radio communication devices, the radio communication method comprising:

The present invention relates to a radio communication device, a radio communication system, and a radio communication method.
At present, specifications of Long Term Evolution (LTE) systems or LTE-Advanced (LTE-A) which are based on LTE systems have been completed or examined in 3rd Generation Partnership Project (3GPP) which is a standardization organization. In LTE, Release 12 is drawn up from 3GPP Release 8 as an international specification. After 3GPP Release 10, LTE is called LTE-A. Further, 5th generation (5G) mobile communication which is subsequent to 4th generation (4G) mobile communication has also been started to be examined since 2013.
On the other hand, in data communication, a communication protocol called Transmission Control Protocol/Internet Protocol (TCP/IP) is used in some cases. TCP/IP is, for example, a protocol in which TCP and IP are combined and is used as a standard protocol in the Internet or the like. For example, IP is a communication protocol used to relay packets in the Internet. TCP is a transmission control protocol and is a protocol that provides a communication service in an intermediate layer between an application program and IP.

FIG. 2 is a diagram illustrating a configuration example of a radio communication system.
FIG. 3 is a diagram illustrating a configuration example of a base station device.
One disclosure provides a radio communication device, a radio communication system, and radio communication method capable of shortening a delay time taken to transmit TCP ACK.
Further, one disclosure provides a radio communication device, a radio communication system, and a radio communication method capable of improving throughput of TCP.
Hereinafter, embodiments will be described in detail with reference to the drawings. Problems and embodiments of the present specification are exemplary and do not limit the scope of the rights of the present application. In particular, when the expressions are the same technically despite differences in the expressions of the description, the technology of the present application can be applied despite the different expressions and does not limit the scope of the rights.
