Description

一种计算辅小区组测量间隔的方法和装置 技术领域
本文涉及但不限于移动通讯领域,尤指一种计算辅小区组(SCG)测量间隔的方法和装置。
背景技术
3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)作为全球最重要的移动通信标准组织之一,制定的LTE(Long Term Evolution,长期演进)目前已成为全球最主流的宽带移动通信标准。LTE一方面继承了2G、3G蜂窝移动通信中的经典技术,另一方面又引入了最前沿的无线通信技术突破,其中主要的经典技术包括多天线发射、在第三代移动通信中的Turbo信道编码、链路自适应、HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)等,进一步提升了系统性能。随着LTE在全球范围内广泛部署,LTE的标准进程也在不断推进,目前LTE标准已经发展到R13阶段。
由于移动互联网的迅猛发展,移动用户对于系统容量需求不断增大,并且呈现出指数增长趋势,现有的系统容量已不足以满足不断增长的业务需求。考虑到大部分业务发生在热点区域和室内,因此Small cell(小小区)无疑成为解决该问题的重要方式。2013年1-9月3GPP分别对Small cell物理层和高层立项研究。Small cell物理层研究主要包括256QAM(Quadrature Amplitude Modulation,正交振幅调制)高阶调制、降低开销、跨子帧调度、小小区开关与小小区发现、空口同步等;Small cell高层研究内容主要包括以控制面和用户面分离为基础的宏基站与微基站的双连接技术。Small cell双连接作为重要的small cell高层增强技术,使得终端可以同时保持与MeNB(宏基站)、SeNB(微基站)的连接,有效提升了单用户吞吐量,同时优化移动性性能,并且降低切换产生的信令开销。
Small cell双连接场景可以分为同步双连接和非同步双连接。在Small cell同步双连接场景中,MCG(Master Cell Group,主小区组)测量间隔 (measurement gap)和SCG(Secondary Cell Group,辅小区组)measurement gap相对位置固定,因此终端通过MCG measurement gap配置信息即可获得SCG measurement gap配置信息。在Small cell非同步双连接场景中,MCG measurement gap和SCG measurement gap相对位置不固定,因此终端需要根据MCG measurement gap配置信息和辅助信息计算获得SCG measurement gap配置信息,但目前没有一种比较合适的方式。
