5G resource scheduling method based on channel state

Abstract

The invention relates to a 5G resource scheduling method based on a channel state, and belongs to the field of wireless communication. The method comprises the following steps: when resource scheduling is carried out in a scheduling period, generating a channel state weighting factor according to a CQI fed back by UE; when the channel quality is good, influencing the user priority at the current scheduling moment by calculating the RB allocated to a user in a front-section time window; when the channel quality is poor, actively improving the user priority at the current scheduling moment by utilizing an exponential function; and combining the channel state weighting factor and an M-LWDF algorithm to obtain the priority of resource scheduling of each user, and allocating the resources to the user with the highest priority. On the basis of the M-LWDF algorithm, the current channel state of the user and the resource allocation situation in the front-end time window are fully considered, and the packet loss rate is reduced while the fairness of a 5G resource scheduling system is effectively improved.

Description

technical field [0001] The invention belongs to the field of wireless communication, relates to the field of wireless service resource scheduling in a wireless communication network, and in particular relates to a channel state-based 5G resource scheduling method. Background technique [0002] With the rapid development of network and information technology, people's demand for wireless mobile communication network is getting higher and higher. As the main evolution direction of mobile communication system, 5G will Obtain broad market development prospects. In order to truly meet the above demand indicators, for users accessing the network, it is self-evident to rationally schedule and allocate resources under the premise that the external environment and public resources are limited. A good system resource scheduling algorithm can greatly affect the downlink performance. The classic packet scheduling algorithms in the 3GPP LTE system mainly include: Round Robin (RR), Maxi...

However, this algorithm can only guarantee the long-term fairness of users, but the short-term fairness cannot be guaranteed

[0006] In view of the complex channel environment caused by ultra-dense heterogeneous networks in the 5G era, the above-mentioned algorithms cannot well meet the needs of 5G resource scheduling. Therefore, a new 5G resource scheduling method is urgently needed
