Example Embodiment

[0019]In the network, EMBB and URLLC are two main business types, so we use the Internet as an application scenario for the EMBB and URLL resource multiplexing methods.

[0020]In one embodiment, iffigure 1 As shown, the present disclosure provides an EMBB and URLLC resource multiplexing method for safeguard service requirements, including the following steps:

[0021]S100: According to the minimum rate requirements of EMBB users, the resources that meet their minimum rate requirements are allocated;

[0022]S200: Allocate the remaining resources in order according to the channel gain descending order of the EMBB user;

[0023]S300: Mixed type URLLC users arrive in microlands;

[0024]S400: Treat a URLLC service that is up to the previous micro slog at the next micrographic presence, the seizure policy that guarantees the requirements of the EMBB service.

[0025]The core idea of ​​this program is that first, calculates the number of resource blocks required for each EMBB user to meet its minimum rat...

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...
