Problems solved by technology

[0004] In the above FOV transmission scheme, when the viewing angle of the VR service changes greatly in a short period of time, the VR terminal needs to download the VR picture stream corresponding to the new viewing angle from the server, which will cause large burst data transmission in a short period of time. This leads to a large data delay and affects the transmission effect of VR services.

Abstract

The present disclosure discloses a resource switching method, which belongs to the technical field of wireless communication. The method includes: receiving viewing angle rotation information reportedby a terminal, the terminal being a terminal that runs a service corresponding to a VR / AR service, and the viewing angle rotation information being reported, by the terminal, when the viewing angle rotation angle of the terminal in the measurement time window exceeds the viewing angle rotation angle threshold; switching a frequency domain resource used by the terminal from a first frequency domain resource to a second frequency domain resource. Through the above solution, a base station can switch the frequency domain resources used by the terminal in advance before the arrival of large datatransmission, so that when large data transmission arrives in a short time, the terminal has a larger bandwidth available, thereby reducing delay during large-data-volume VR / AR picture transmission inshort time, and improving transmission effect of VR / AR services.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a resource switching method, device and storage medium. Background technique [0002] In current virtual reality (Virtual Reality, VR) applications, it is usually necessary for a server located on the network side to transmit data such as a VR picture to a terminal. [0003] In the related art, the field of view (Field of View, FOV) transmission technology is commonly used in VR applications, and it is a technology for transmitting based on the perspective picture currently viewed by the user. When transmitting VR images through the FOV transmission technology, the VR images in the direction facing the current viewing angle are encoded at a higher resolution, while the VR images in other directions are encoded at a lower resolution. [0004] In the above FOV transmission scheme, when the viewing angle of the VR service changes greatly in a short perio...
