Problems solved by technology

[0004] However, when using the above scheduling method, if a UE with high priority, such as UE with k=8, has a large traffic volume, it is likely to be scheduled all the time, resulting in UEs with low priority, such as UE with k=4 or k=6 The UE is never scheduled and cannot guarantee the Quality of Service (QoS for short)

Abstract

The present application provides an uplink scheduling method and device. The uplink scheduling method of the present application includes: determining the uplink physical channel resources respectively reserved for three types of user equipment UEs in the current resource adjustment period, the three types of UEs include the first UE with a processing delay of 4, and the first UE with a processing delay of 6 The second UE and the third UE with a processing delay of 8; obtain the buffered data amount of the UE to be scheduled, the UE is the first UE, the second UE or the third UE; according to the amount of buffered data from the reserved uplink physical channel resources Allocate uplink physical channel resources to the UE. This application improves the utilization rate of uplink channel physical resources and guarantees the QoS of the UE.

Description

technical field [0001] The present application relates to communication technologies, and in particular to an uplink scheduling method and device. Background technique [0002] With the development of the mobile Internet, a large number of application services that meet various specific functions have emerged. Some of these services have strict requirements on data delay, such as online games, snapping up, grabbing red envelopes, etc. These services usually require The delay of user data is as short as possible. In Long Term Evolution (LTE for short), Transmission Time Interval (TTI for short) is an important indicator affecting user data delay. Currently, the TTI used is 1 ms. A data block is sent once in 1ms, and the receiving end receives a data block every 1ms. The R15 protocol of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) introduces short TTI (short TTI, sTTI for short), for example, Orthogonal Frequency Division Multip...
