Device and method for transmitting/receiving data in wireless communication system
First Claim
1. A method for operating an apparatus for receiving a data regarding a transmission control protocol (TCP) in a wireless communication system, the method comprising:
- identifying an access node for the apparatus having been changed from a first node using a first radio access technology (RAT) to a second node using a second RAT;
identifying a first bandwidth regarding the first RAT and a second bandwidth regarding the second RAT;
generating a TCP acknowledgment (ACK) message based on another TCP ACK message that has been lastly transmitted to another apparatus;
transmitting, to the other apparatus, the TCP ACK message before a TCP data is received if the second bandwidth exceeds the first bandwidth; and
receiving the TCP data according to a congestion window with a size increased by the other apparatus based on the TCP ACK message.

Abstract
The present disclosure relates to a 5G or pre-5G communication system to be provided in order to support a higher data transmission rate than a 4G communication system such as LTE. The present disclosure relates to a device and method for transmitting and/or receiving data in a wireless communication system. The present disclosure enables determining whether an access change occurs from a first node using a first Radio Access Technology (RAT) to a second node using a second RAT and enables transmitting information instructing to adjust the TCP transmission rate to a TCP transmission device when an access change occurs from the first node to the second node.

7. A method for operating an apparatus for transmitting a data regarding a transmission control protocol (TCP) in a wireless communication system, the method comprising:
-
receiving a TCP ACK message from another apparatus with an access node for the other apparatus having been changed from a first node using a first radio access technology (RAT) to a second node using the second RAT; determining whether the TCP ACK message is transmitted before the other apparatus has received a TCP data; increasing a size of a congestion window based on determining that the TCP ACK message is transmitted before the other apparatus has received the TCP data; and transmitting the TCP data to the other apparatus through the congestion window with the increased size. - View Dependent Claims (8)

9. An apparatus for receiving a data regarding transmission control protocol (TCP) in a wireless communication system, the apparatus comprising:
-
at least one transceiver; and at least one processor operatively coupled to the at least one transceiver, wherein the at least one processor is configured to; identify an access node for the apparatus having been changed from a first node using a first radio access technology (RAT) to a second node using a second RAT; identify a first bandwidth regarding the first RAT and a second bandwidth regarding the second RAT; generate a TCP ACK message based on another TCP ACK message which has been lastly transmitted to another apparatus; transmit, to the other apparatus, the TCP ACK message before a TCP data is received if the second bandwidth exceeds the first bandwidth; and receive the TCP data according to a congestion window with a size increased by the other apparatus based on the TCP ACK message. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
