Embodiment Construction

[0052] Embodiments of the present invention provide an uplink resource scheduling method and device, which are used to solve the technical problem that traditional uplink resource scheduling methods cannot satisfy resource allocation for different services such as low delay, high reliability, and large capacity.

[0053] There are three major application scenarios for 5G, including eMMB (Enhanced Mobile Broadband, enhanced mobile broadband), uRLLC (Ultra Reliable&Low Latency Communication, low-latency, high-reliability communication) and mMTC (Massive Machine Type Communication, massive Internet of Things communication) . According to time constraints, uRLLC’s business is real-time messaging. In this scenario, it has high requirements for latency, often reaching the 1ms level, such as automatic control of metering collection, real-time collaborative robots, and other real-time monitoring and real-time early warning. Data, if the transmission process of such data takes too long...

Abstract

The invention discloses an uplink resource scheduling method and device, which are applied to a base station, the base station comprises a cache queue, a plurality of slices and a resource block queue, and the method comprises the following steps: receiving uplink resource requests sent by a plurality of preset user terminals; judging whether the cache queue is in an idle state or not in a presetscheduling period; if the cache queue is not in the idle state, selecting a to-be-allocated resource block from the resource block queue and allocating the to-be-allocated resource block to the plurality of slices; and allocating the allocated resource blocks in each slice to each user terminal. Therefore, the time delay of uplink resource scheduling is reduced, and the reliability of uplink resource scheduling of large-capacity services is improved.

Description

technical field [0001] The present invention relates to the technical field of resource scheduling, in particular to an uplink resource scheduling method and device. Background technique [0002] The wireless resources in the mobile communication system are limited. These wireless resources include resources such as frequency, time, space, power, and codewords. Then, how to make full use of the limited wireless resources to meet people's growing wireless service needs, this is Tasks that need to be completed by the radio resource scheduling and allocation mechanism. [0003] There are many definitions of resource scheduling and allocation mechanisms, but the widely accepted definition is as follows: the scheduler on the base station must be able to dynamically control the allocation of time-frequency resources in real time, and allocate time-frequency resources to a certain user within a certain period of time. The scheduling method requires a balance between user QoS (Qual...
