AI Technical Summary
Technical Problem
In wireless communication systems, the buffer status report (BSR) of IoT devices is delayed or unable to report, making it difficult for base stations to effectively allocate resources.
Method used
By sending specific signaling between the network device and the terminal device, the terminal device does not need to send a buffer status report, and the network device directly schedules resources based on the preset data size.
Benefits of technology
It reduces the power consumption of terminal devices, reduces data transmission delay, and improves resource utilization, and is especially suitable for environments with high power consumption requirements.

Abstract
The invention provides a data transmission method and device, which are applied to the fields of environmental Internet of Things and the like, and the method comprises the following steps: sending a paging message to a terminal device, the paging message being used for paging the terminal device; and sending scheduling information to the terminal device, the scheduling information being used for scheduling a resource for transmitting the first data, the resource being determined according to a data size indicated by first information, and the first information being from a core network device. Through the method, the network equipment can determine the data size of the first data according to the first information, so that resources can be scheduled according to the data size without waiting for a buffer status report from the terminal equipment. Under the condition that the terminal equipment does not send the buffer status report, the network equipment performs resource scheduling for the terminal equipment, so that the power consumption of the terminal equipment can be reduced, the data transmission time delay is reduced, the resource utilization rate is improved, and the method is particularly suitable for scenes such as environmental Internet of Things.
