Description

一种发送 RRC信令的方法、 基站和系统 本申请要求于 2012 年 12 月 31 日提交中国专利局、 申请号为 CN 201210593797. 发明名称为 "一种发送 RRC信令的方法、 基站和系统" 的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及通信技术领域, 具体涉及一种发送 RRC信令的方法、 基站 和系统。 背景技术
长期演进技术( Long Term Evolution,简称 LTE )第 10版本( Release 10 ), 即 R10系统会支持载波聚合技术(Carrier Aggregation, 简称 CA ), 即可以 把多个成员载波 (Component Carrier, 简称 CC)同时分给一个用户设备 ( User Equipment, 简称 UE )用于支持更高的数据速率传输。 对于支持 CA的 UE 来讲, 可以有一个主小区 (Primary Cell, 简称 PCell )和一个或多个辅小区 ( Secondary Cell, 简称 SCell )。
LTE 的未来版本比如 R12 , 可能会支持 LTE- Advanced 多流聚合
( Multi- Stream Aggregation, 简称 MSA )。 这是在 3 GPP LTE- Advanced未来 演进大会上提出的提升小区边缘速率的新技术。 MSA不仅可应用于宏蜂窝 小区的站间协调以提高边缘用户速率, 也可以应用在大小站异构组网场景 下提高用户的峰值速率和简化移动性管理, 从而为用户打造业务一致化体 验。 在未来移动宽带发展中, 运营商最关注的是用户体验。 在移动通信覆 盖区域内, 不同地理位置的用户理应享受相同质量的移动服务。 但是在蜂 窝通信系统中, 小区间边缘的系统性能往往是移动通信系统设计上的最大 难题之一。 作为未来无线通信的主流技术, LTE及其演进技术如果不能提 高小区边缘位置的用户体验, 其广泛应用将受到极大的挑战。 MSA多流聚 合的核心思想是通过系统的动态调节, 让用户总是可以从信号最好的小区 或小区组接收到下行数据并进行数据流聚合。 上行方向釆用类似方式, 用 户总是在向信号最好的小区或者小区组传输上行数据并在网络侧进行数据 流汇聚。
对于支持 CA的 UE来讲, MSA可以看做是不同基站( Evolved NodeB, 简称 eNB )的小区聚合。 R11之前的版本, UE的 PCell和 Scell都属于同一 个 eNB。 而对于 MSA的 UE来讲, PCell和 SCell可以分属于不同的 eNB。
对于宏基站 Macro eNB和微基站 Pico eNB是同覆盖场景, UE可以同 时接收到 Macro eNB和 Pico eNB的信号。 Macro eNB实现 UE的控制面功 能, 包括 UE的移动性管理功能。 Pico eNB主要是用于承载室内低移动性 数据业务, 实现用户面功能。 也就是说空口的用户面和控制面釆用分离的 方式, 即 C/U分离, Pico eNB到 UE的链路只负责用户面数据的传输, Pico eNB到 UE的控制面信令由 Macro eNB到 UE的链路进行传输。 Pico eNB 和 Macro eNB之间是有线连接,类似于 X2 like接口。一旦 UE和 Macro eNB 建立起 RRC连接, Macro eNB会将 Pico eNB需要的 RRC配置信息通过新 定义的接口消息传递给 Pico eNB,在 Macro eNB与 UE建立 RRC连接的同 时, 可以将相关配置信息发送给 Pico eNB。
C/U分离也可以是广义的分离, 参见图 1所示, 图 1为现有技术中的 协议栈架构, Pico eNB为信令无线 载( Signalling Radio Bearers,简称 SRB ) 建立从物理层(Physical, 简称 Phy )到分组数据汇聚协议层(Packet Data Convergence Protocol, 简称 PDCP ) 的协议实体。 UE侧建立 2套 SRB, 分 别对应 Macro eNB和 Pico eNB, 此协议架构中, Macro eNB可以将生产的 RRC信令直接传送给 UE, 如图 1中虚线 A所示; Pico eNB也会传送 RRC 信令给 UE, 但是该 RRC信令是由 Macro eNB生成的, 如图 1中虚线 B所 示。
参见图 2所示,图 2为现有技术中另一种协议栈架构, Pico eNB为 SRB 建立从 Phy到 RRC的协议实体,不过 Pico eNB只负责底层配置 ,即 Pico eNB 的 Phy, MAC, RLC的配置由 Pico eNB的 RRC完成。 UE侧建立 2套 SRB, 分别对应 Macro eNB和 Pico eNB, 此协议架构中, Macro eNB可以将生产 的 RRC信令传送给 UE, Pico eNB也可以生成 RRC信令, 并将该 RRC信 令发送给 UE。
在对此方法的研究和实践过程中,本发明的发明人发现,为支持 MSA, 用户设备侧需要建立 2套 SRB来支持来自 Macro eNB和 Pico eNB的 RRC 信令, 从而导致设计的复杂度和成本的增加。 发明内容

为了使本技术领域的人员更好地理解本发明方案, 下面将结合本发明 实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分的实施例, 而不是全部的实施 例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创造性劳动 前提下所获得的所有其他实施例, 都应当属于本发明保护的范围。 本发明实施例提供一种发送 RRC信令的方法, 包括:
