Document Type and Number:

WIPO Patent Application WO/2023/104029

Kind Code:

A1

Abstract:

The present disclosure provides a downlink resource preemption method and apparatus and a related device, and relates to the technical field of communications. The method comprises the following steps: acquiring wireless resources to be scheduled of an ultra-reliable low-latency communication (URLLC) user equipment (UE), wherein the wireless resources to be scheduled comprise mini-slots where the URLLC UE is located, pre-occupied downlink beam resources and frequency domain resources; in the same mini-slot, when a conflict exists between the frequency domain resources of the URLLC UE and frequency domain resources of an enhanced mobile broadband (eMBB) user equipment (UE), determining the total amount of pre-occupied beams; and, according to the total amount of pre-occupied beams, confirming the preempted state of the eMBB UE in order to schedule the wireless resources to be scheduled of the URLLC UE. Provided in the present disclosure are a downlink resource preemption method and apparatus and a related device that take into account the impact on resource preemption of both the wireless resources and the maximum total amount of service beams scheduled by a cell at the same moment in order to increase the utilization rate of the wireless resources.
