附图说明
附图用来提供对本发明技术方案的进一步理解,并且构成说明书的一部分,与本申请的实施例一起用于解释本发明的技术方案。
图1为LTE***中的MAC层结构示意图;
图2为本公开实施例***参数集的配置方法的流程示意图;
图3为本公开实施例的MAC层结构示意图;
图4为本公开实施例中***参数集配置装置的组成结构示意图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,下文中将结合附图对本公开的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机***中执行。并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
长期演进(Long Term Evaluation,LTE)***中,MAC层的结构如图 1所示,MAC层主要通过传输信道给逻辑信道提供数据传输和负责无线资源分配,实现HARQ)、LCP处理、复用解复用((De-)Multiplexing,MUX)等功能,此外,还包含随机接入控制(Random Access Control)、上报DRX、SR、BSR、PHR、激活去激活(ACTIVE/DEACTIVE)、PDCCH监测(PDCCH mornitor)、时间对齐(Time Alignment,TA)维护、SPS等功能。
目前,业界提出了5G技术目标:到2020年左右,实现每区域1000倍的移动数据流量增长,每用户设备(User Equipment,UE)10到100倍的吞吐量增长,连接设备数10到100倍的增长,低功率设备10倍的电池寿命延长,以及端到端5倍延迟的下降。从应用场景的角度而言,5G将采用一个统一的技术架构来支持增强移动宽带(enhanced Mobile BroadBand,eMBB)业务,海量机器类(massive Machine Type Communication,mMTC)业务和高可靠低时延(Ultra Reliable and Low Latency,URLLC)业务,这些业务对时延的要求是不一样的。为了满足不同的业务需求,提出numerology的概念,指的是通信***所用的一套参数,包括子载波间隔、符号长度、循环前缀(Cyclic Prefix,CP)长度等等。在LTE/LTE-A中,子载波间隔(Subcarrier Spacing,SCS)是固定的15kHz,而在5G中SCS将会设为15*(2^n)kHz,其中n可以取负数。也就是说SCS可以设为3.75kHz、7.5kHz、15kHz、30kHz、60kHz、120kHz等等,SCS的取值直接会影响符号在时域的长度。每个***参数集,对应的TTI长度(TTI duration)可以不同。
引入numerology后,MAC层如何在支持多个numerology的情况下各个功能正常运转并发挥最大效能,以满足不同业务的不同需求,相关技术中未提出相应的解决方案。本申请提出一种***参数集的配置方法及装置,能够确保MAC层在支持多个numerology的情况下各个功能正常运转并发挥最大效能,以满足不同业务的需求。
