BWPBandwidth Part（BWP）is an important concept in 5G and can be considered as UEs working bandwidth.A continuous bandwidth resource allocated（分配）to UE by network is a necessary configuration（配置）for 5G UE to access NR network.BWP是5G NR中一个重要的概念，BWP可理解为UE的工作带宽。网络侧给UE分配的一段连续的带宽资源，它是5G UE接入NR网络的必备配置。将咖啡屋学习模式应用于小学生的作文教学中，落实到作文教学的等各个环节，充分激发了学生写作的主动性和积极性，加强了学生间的了解与沟通，培养了良好的写作习惯，提高了学生的写作水平。Application scenarios:场景1：对接收机带宽(如20MHz)小于整个系统带宽(如100MHz)的UE提供支持。场景2：通过不同带宽大小的BWP之间的转换和自适应来降低UE的电量消耗。场景3：不同BWP，配置不同参数集，承载不同业务。Scenario 1:support UE whose receiver bandwidth(such as 20MHz)is less than the bandwidth of the whole system(such as 100MHz).Scenario 2:reduce the power consumption of UE through the conversion and adaptation between BWPs with different bandwidth sizes.Scenario 3:different BWPs are configured with different parameter sets to carry different businesses.将咖啡屋学习模式应用于小学生的作文教学中，落实到作文教学的等各个环节，充分激发了学生写作的主动性和积极性，加强了学生间的了解与沟通，培养了良好的写作习惯，提高了学生的写作水平。场景4：载波中可以配置不连续的频段。场景5：载波中可以预留频段，用于支持尚待定义的传输格式。Application scenarios:Scenario 4:discontinuous

following categories:Initial BWP:the BWP used in the initial access phase of UE(obtained through system messages).Dedicated BWP:BWP configured by UE in RRC connection state;The protocol stipulates that one UE can configure up to four dedicated bwps through RRC signaling.Active bwp:the BWP activated by UE at a certain time in RRC connection state is one of the dedicated BWP.The agreement stipulates that UE can only activate one configured dedicated BWP at a certain time in RRC connection state.Default bwp:when the UE is in RRC connection state,when its BWP inactivity timer times out,the BWP that the UE is working on is also one of the dedicated bwps.The RRC signaling indicates which configured dedicated BWP the UE uses as the default BWP.将咖啡屋学习模式应用于小学生的作文教学中，落实到作文教学的等各个环节，充分激发了学生写作的主动性和积极性，加强了学生间的了解与沟通，培养了良好的写作习惯，提高了学生的写作水平。Configuration Configuration requirements of BWPrequirements of BWP On each carrier,the UE can be configured

not transmit on PUSCH or PUCCH.For the active cell,UE does not transmit SRS outside BWP.将咖啡屋学习模式应用于小学生的作文教学中，落实到作文教学的等各个环节，充分激发了学生写作的主动性和积极性，加强了学生间的了解与沟通，培养了良好的写作习惯，提高了学生的写作水平。Technical advantages of BWP1.UE does not need to support all bandwidth,but only needs to meet the minimum bandwidth requirements,which is conducive to the development of low-cost terminals and promote industrial development;2.When the traffic volume of UE is small,UE can switch to low bandwidth operation,which can significantly reduce power consumption;3.When 5g adds new technology,it can directly run the new technology on the new BWP,ensuring the forward compatibility of the system;4.Adapt to business needs and dynamically configure BWP for business.若素素材若素素材谢谢
