Title:
METHOD AND APPARATUS FOR TCP CONGESTION CONTROL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/043607
Kind Code:
A1
Abstract:
The present disclosure describes apparatuses and a method performed by a base station in a wireless communication system. Specifically, the method performed by the base station in a wireless communication system according to various embodiments of the present disclosure may comprise the steps of: when a packet data control protocol (PDCP) service data unit (SDU) is unable to be delivered from a PDCP layer to a lower layer, storing the PDCP SDU in a buffer; when the size of the PDCP SDU stored in the buffer is equal to or greater than a preconfigured threshold capacity, including information indicating a TCP congestion situation in a field within the header of a first transmission control protocol (TCP) acknowledgement (ACK) transmitted by a terminal to a server; transmitting, to the server, a second TCP ACK including information indicating the TCP congestion situation; and receiving, from the server, a TCP packet including information indicating that the TCP congestion situation has been identified. Various other embodiments identified through the specification are possible.
