Problems solved by technology

Under this preemptive hole punching method, an important optimization problem is the allocation of resources preempted by URLLC transmissions between eMBB users. The decoding results of transmissions received by eMBB users directly depend on URLLC preemption. eMBB users The more resources preempted by URLLC, the greater the probability of decoding failure, and such decoding failure will cause the loss of eMBB utility

Embodiment Construction

[0019] In the Internet of Vehicles, eMBB and URLLC are two main types of services. Therefore, in the following embodiments, we use the Internet of Vehicles as an application scenario of the resource multiplexing method of eMBB and URLLC.

[0020] In one embodiment, such as figure 1 As shown, the present disclosure provides an eMBB and URLLC resource multiplexing method that guarantees service requirements, which includes the following steps:

[0021] S100: According to the minimum rate requirement of the eMBB user, allocate resources that meet the minimum rate requirement;

[0022] S200: Allocate remaining resources in descending order of channel gains of eMBB users;

[0023] S300: URLLC users of mixed types arrive in mini-slots;

[0024] S400: At the beginning of the next mini-slot, process the URLLC service arriving in the previous mini-slot according to the preemption policy that guarantees the eMBB service requirement.

[0025] The core idea of ​​this solution is to fir...

Abstract

An eMBB and URLLC resource multiplexing method for guaranteeing service requirements comprises the following steps: S100, according to the lowest rate requirement of an eMBB user, allocating a resource meeting the lowest rate requirement of the eMBB user; S200, sequentially allocating residual resources according to a descending order of channel gains of the eMBB users; S300, enabling the URLLC users of the mixed type to arrive at the micro time slot; and S400, when the next micro time slot starts, processing the URLLC service arrived at the previous micro time slot according to a preemptive strategy for guaranteeing the eMBB service requirement. According to the method, the reliability of eMBB and URLLC users is ensured, and particularly, strict guarantee can be provided for eMBB service requirements.

Description

technical field [0001] The disclosure belongs to the technical field of wireless communication, and in particular relates to an eMBB and URLLC resource multiplexing method for guaranteeing service requirements. Background technique [0002] 5G New Radio (NR) provides three main services: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive IoT (mMTC). eMBB is an extension of LTE-Advanced services designed to provide extremely high data rates for content delivery, which can significantly improve the quality of experience for bandwidth-hungry in-vehicle entertainment applications such as video streaming, augmented reality and Virtual reality, video-on-demand services, etc., such network services with high bandwidth and high data rate requirements, are often used by us, and the main focus is on maximizing the data rate. Therefore, for eMBB users, reliability is crucial. The eMBB reliability is the proportion of eMBB users who meet th...
