Description

(Cross-reference of related applications) This application claims priority to Chinese Patent Application No. 202111467958.8, filed in China on December 3, 2021, and all contents of that application are incorporated herein by reference. This application belongs to the field of telecommunications technology, and specifically relates to information transmission methods, apparatus, terminals, and network-side equipment. For services with latency requirements, such as extended reality (XR) services, the XR service has arriving periodic image frames. In an image frame data transmission model based on a group of pictures (GoP), there are I-frames, P-frames, and B-frames, where the I-frame has the largest data volume, followed by the P-frame, and then the B-frame. I-frames appear periodically, with some P-frames and B-frames interspersed between every two I-frames. If multiple users transmit XR services to a single cell, and the XR services are based on a GoP model, then if the I-frames of multiple users' XR services appear very close together, a very large air interface capacity will be required to transmit these I-frames, potentially leading to air interface congestion. However, at other times, if the number of I-frames is relatively small, the air interface capacity may not be fully utilized. In other words, the utilization of the air interface capacity is not sufficiently effective, resulting in relatively low transmission performance.
