摘　　要：5G NR引入部分带宽(BWP)概念,它是在系统信道带宽内配置的一组连续资源块上,完整实现5G应有的功能特性。BWP的应用对于国内运营商重耕低频5G NR而言至关重要,尤其对于低频大带宽FDD NR而言,要考虑网络对不同终端能力的向下兼容性。通过描述3GPP规范中的BWP概念、BWP配置方法和BWP切换机制,讨论UE终端对BWP支持能力,提出部署BWP应用场景和基于2.1 GHz NR的BWP配置方法,为5G网络演进规划提供指导意见。5G NR introduces a fundamental concept called bandwidth part(BWP),which fully realizes the characteristics of 5G on a set of contiguous resource blocks configured inside a channel bandwidth.The application of BWP is crucial for domestic vendors to refarm low-frequency 5G NR,especially for low-frequency and large-bandwidth FDD NR,it is necessary to consider the backward compatibility of the network to different terminal capabilities.By describing the BWP concept,BWP configuration method and BWP handover mechanism in 3GPP specification,it discusses the support capability of UE terminal for BWP,and proposes the deployment scenarios of BWP and BWP configuration method based on 2.1 GHz NR,which provides guidance for 5G network evolution.
