AI Technical Summary
⚠Technical Problem
The transmission rate of terminal devices is difficult to adapt to changes in wireless communication networks, leading to problems such as data overflow, buffer overflow, or packet loss.
⚗Method used
The first network element adjusts the transmission rate based on the terminal's buffer size. The terminal device can request or adjust the transmission rate itself to match the channel conditions, or the access network element can recommend a suitable transmission rate based on buffer occupancy.
🎯Benefits of technology
It enables flexible adjustment of transmission rate to adapt to changes in wireless communication networks, ensures the availability and reliability of data transmission, and avoids buffer overflow and packet loss.

Abstract
A communication method and apparatus, belonging to the field of communications. The method comprises: receiving indication information regarding cache size from a terminal, the indication information regarding cache size being used for indicating the cache size of the terminal; on the basis of the indication information regarding cache size, determining first information, the first information being used for adjusting the transmission rate of the terminal; and sending the first information to the terminal. On the basis of the first information, the terminal can adjust the transmission rate, achieving flexible adjustment of the transmission rate, thereby helping to match constantly changing air interface channel conditions in a wireless communication network. In addition, the above-described first information is determined on the basis of the cache size of the terminal. Compared with the solution of determining the transmission rate on the basis of the amount of data to be transmitted, the above-described solution can prevent the data to be transmitted from overflowing from a cache.
