Description

3G网络和 4G网络载波聚合方法及系统 技术领域
本发明涉及一种载波聚合技术, 尤其涉及一种 3G网络和 4G网络载波 聚合方法及系统。 背景技术
在宽带码分多址( WCDMA, Wideband Code Division Multiple Access ) 网络中, 通用陆地无线接入网 (UTRAN, Universal Terrestrial Radio Access Network ) 包括无线网络控制器(RNC, Radio Network Controller )和基站 ( NodeB ) 两种基本网元, 俗称第三代(3G, 3rd Generation )通信网络。 在长期演进 ( LTE, Long Time Evolution ) 网络中, 演进型的通用陆地无线 接入网 (E-UTRAN, Evolved Universal Terrestrial Radio Access Network ) 包 括演进型基站(eNB )这一种基本网元, 俗称第四代(4G, 4th Generation ) 通信网络。
随着 WCDMA网络的发展,高速下行接收链路分组接入( HSDPA, High Speed Downlink Packet Access ),高速上行发送链路分组接入( HSUPA, High Speed Uplink Packet Access ), 双载波高速下行分组接入 ( DC-HSDPA, Dual Carrier-High Speed Downlink Packet Access )、 双频段双载波高速下行分组接 入( DB-DC-HSDPA, Dual band-Dual Carrier-High Speed Downlink Packet Access ), 双载波高速上行分组接入 ( DC-HSUPA, Dual Carrier- High Speed Downlink Packet Access ), 四载波高速下行分组接入 ( 4C-HSDPA, Four Carrier- High Speed Downlink Packet Access ), 八载波高速下行分组接入 ( 8C-HSDPA, Eight Carrier- High Speed Downlink Packet Access )这些 3G 系统内的多载波聚合技术陆续被引入,使得用户设备( UE, User Equipment ) 的上下行数据传输率不断提高。 对于上述不同维数的多载波技术, 以下行 方向为例, 一个重要的基本特征是: UE必须配备有多条 3G相关的接收数 据处理链( 3G-Receiver Chain ), 可以同时接收处理来自同一个基站同一个 扇区 (sector ) 若干个载波上下行发送来的 3G 数据块。 演进到今天的 WCDMA系统又称为 HSPA + ( High Speed Packet Access+ ) 系统。
随着 LTE网络的发展, 类似 WCDMA多载波聚合概念的技术 ( CA, Carrier Aggregation )也逐渐产生, 以下行方向为例, 截至到目前, LTE系 统内最大可以对 5个下行带宽为 20MHz的载波进行聚合。 载波聚合重要的 基本特征是: UE必须配备有多条 4G相关的接收数据处理链( 4G-Receiver Chain ), 可以同时接收处理来自同一个基站同一个扇区若干个载波上下行 发送来的 4G数据块。
HSPA+网络朝 LTE网络演进的长期过程中, 必然有很长一段时间, 两 种系统同时存在并协同工作, 共同 担着来自或者面向核心网一侧的数据 传输的任务。 比如, 某运营商有两个载波频点资源 Fl、 F2, 将 F1 分配给 HSPA +网络运营使用, 而将 F2分配给 LTE网络运营使用。 只有 3G功能 的 UE只能在 F1上工作, 只有 4G功能的 UE只能在 F2上工作, 同时具备 3G、 4G功能的 UE, 在同一个时间, 只能在 F1或者 F2上工作, 不能同时 在 F1和 F2上工作。 为了充分利用这一类 UE的接收能力和提高下行峰值 速率, 业界提出了第七代(7G, 7th Generation ) 通信技术(3G+4G ) 又称 跨 HSPA +、 LTE系统的载波聚合技术。
图 1为 7G网络的组成结构示意图, 如图 1所示, 7G网络架构中 LTE 的 eNB作为 UE无线资源连接 ( RRC, Radio Resource Connection ) 的主控 制锚点和数据分流控制点。 UE在 eNB某工作载波上的物理下行控制信道 ( PDCCH, Physical Downlink Control Channel )中的调度命令(如资源分配, HARQ ( Hybrid Automatic Repeat ReqUEst )操作相关信息)控制下, 从物 理下行共享信道(PDSCH, Physical Downlink Shared Channel )接收一部分 用户数据。 同时, UE 在 NodeB 某工作载波上的高速共享控制信道 ( HS-SCCH, High Speed Shared Control channel )的调度命令控制下, 从高 速下行共享信道(HS-DSCH, High Speed-Downlink Shared Channel )上接 收另一部分用户数据。锚点 eNB负责将 eNB产生的上层协议数据包进行分 配,按照一定的方式, 决定哪部分从 LTE的空中接口发送,哪部分从 HSPA +的空中接口发送。 被分配到 NodeB的那一部分的协议数据包, 需要通过 eNB和 NodeB之间一个新接口传输, 由 NodeB根据自身协议特点和 HSPA +空中接口的方式进行发送。
在上行方向, UE至少要在与 eNB工作下行频点配对的上行频点上发 送物理上行链路控制信道(PUCCH, Physical Uplink Control Channel ), PUCCH中承载如 HARQ操作相关信息(正确接收确认 ACK/NACK ),调度 请求, 接收信道质量指示等, 以反馈 LTE下行高速数据传输相关的必要信 息。 而 UE是否要在与 NodeB工作下行频点配对的上行频点上发送高速专 用物理控制信道 (HS-DPCCH , High Speed-Dedicated Physical Control channel ), 以反馈 HSPA +下行高速数据传输相关的必要信息, 现有技术尚 未涉及。 通常为了减少 UE 的上行发射功率, 以及减少上行干扰, 倾向于 UE只在 LTE空口进行单系统上行反馈, 而非跨系统同时反馈。 发明内容
