Communication method and apparatus
By having the STA report RTT-related information to the AP, the AP adjusts the sending of TCP packets and TCP ACKs, thus solving the problem of long TCP packet RTT and achieving more efficient transmission control protocol packet transmission.

AI Technical Summary
In existing technologies, the round-trip time (RTT) of Transmission Control Protocol (TCP) messages is relatively long and cannot be effectively reduced. This is mainly due to the excessive waiting time of TCP ACK in the uplink queue of the STA, the unreasonable TCP ACK feedback mechanism, and the inability to transmit messages when the STA enters a sleep state.
The STA reports RTT-related information of TCP packets to the access point (AP), such as the waiting time of TCP ACK in the uplink queue, the maximum RTT delay, the default TCP packet number in the TCP ACK feedback mechanism, the minimum number of TCP packets in the TCP ACK feedback mechanism, and the STA's upcoming sleep state. The AP adjusts the sending of TCP packets or TCP ACKs based on this information to optimize the transmission process.
By optimizing the sending process of TCP packets and TCP ACKs, the RTT of TCP packets is effectively reduced, transmission efficiency is improved, and delays caused by waiting and sleep states are avoided.
