Description

指示用户设备双频段非相邻载波聚合能力的方法及系统 技术领域
本发明涉及一种指示用户设备双频段非相邻载波聚合能力的技术， 尤 其涉及一种指示用户设备双频段非相邻载波聚合能力的方法及系统。 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。 随着 WCDMA网络的发展， 高速下行链路分组 接入（HSDPA, High Speed Downlink Packet Access ), 高速上行链路分组接 入（HSUPA, High Speed Uplink Packet Access ), 双小区高速下行分组接入 ( DC-HSDPA, Dual Cell-High Speed Downlink Packet Access ), 双频段双小 区高速下行分组接入 ( DB-DC-HSDPA, Dual Band-Dual Cell-High Speed Downlink Packet Access ),双小区高速上行分组接入（ DC-HSUPA, Dual Cell- High Speed Uplink 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 )这些技 术陆续地被引入，使得 UE的数据传输率不断提高。这些技术的本质就是用 户设备 ( UE, User Equipment )将单 /双频段内的载波进行聚合。
随着 UE自身射频（ RF, Radio Frequency )模块的发展， UE已经能从 早期的单 /双频段相邻载波聚合， 逐渐发展到可以进行单 /双频段内非相邻载 波聚合。 为了方便说明， 下面用 A表示单频段， （A, B )表示双频段组合， A100表示频段 A内的某个频点， 由于 WCDMA FDD ( Frequency Division Duplexing )载波都是 5M带宽，其相邻频点表示成 A95和 A105;同理（ A100, B200 )表示双频段内两个组合频点，这里 100, 200没有绝对数值大小意义， 仅仅起到中心频率原点参考作用。
双频段内非相邻载波聚合能力表示 UE 能分别将 A85, A95, A100, A110等这些不相邻的载波聚合起来， 同时再将 B190, B200, A205, A215 等这些不相邻的载波聚合起来， 其中 （A, B )双频段内具体分别能同时聚 合多少个载波， 在现有 3GPP规范中， 已经有明确的表达方式。 除此之外， UE在双频段（A, B ) 内分别能将最大频率间隔多少的载波聚合到一起， 目前尚无表达方式方法。 如果沿用已有的单频段非相邻载波聚合能力表达 方式, 即用 A频段中的一个 Support for non-adjacent aggregation表达 UE能 将 A频段内最大频率间隔多少的载波聚合到一起 (此时视 A为单频段）， 再用 B频段中的另一个 Support for non-adjacent aggregation表达 UE能将 B 频段内最大频率间隔多少的载波聚合到一起（此时视 B为另一个单频段， 而非 A的联合双频段）。 但是， 上述这些并不能真正全面表达 UE在双频段 ( A, B ) 内分别能将最大频率间隔多少的载波聚合到一起。 比如： 某 UE 能够单独在 A频段内将 A90, A100, A110三个不相邻载波聚合在一起， 同 时能够单独在 B频段内将 B190, B200, B210三个不相邻载波聚合在一起， 同时也能够联合将（ A95, A100, A105 , B195 , B200, B205 )六个载波聚 合在一起， 同时又能够联合将（ A90, A100, A110, B195 , B200, B205 ) 六个载波聚合在一起， 但却不能同时将（A90, A100, A110, B190, B200, B210 ) 六个载波聚合在一起， 那么如果网络基于上述双频段非相邻载波聚 合能力表达方式， 就可能给出错误配置， 从而载波聚合操作失败。
同时， UE支持双频段非相邻载波聚合能力时， 在双频段配置 3载波， 4载波的场景列表如表 1所示， 包括但不限定于表 1所示的场景。 表 1中， 灰色方格表示对应场景所应用的载波。 可见应用场景很多， 需要找到一个 较佳的方式，清晰简单地将 UE支持的场景指示清楚， 并将该指示信息传输 给网络侧如无 网络控制器（ RNC, Radio Network Controller )0

实施例四
图 2为 UE上报自身支持的载波聚合能力的示意图， 如图 1所示， 在
UE在发送给 RNC的 UE Capability Information消息中包含 Max-Hole Cell of non-adjacent Carrier Combination List, Max-Hole Cell Combination信元以指 示在双频段非相邻载波聚合能力， 具体如何指示与实施例二中相同， 此处 不再赘述。
图 3 为本发明指示用户设备双频段非相邻载波聚合能力的方法的流程 图， 如图 3 所示， 本发明指示用户设备双频段非相邻载波聚合能力的方法 具体包括以下步驟：
步驟 301 , 网络侧 （ RNC )通过 RRC连接建立完成消息获得 UE双频 段非相邻载波聚合能力。 本发明中， UE为支持双频段非相邻载波聚合的 UE。 UE通过发送给 RNC的 RRC Connection Setup Complete消息或 UE Capability Information消 息上报 UE 支持的每个频段组合中各个频段上支持非相邻载波聚合能力组 载波个数。
步驟 302, 网络侧决策业务是否支持双频段非相邻载波配置的多载波。 RNC获取 UE支持双频段非相邻载波聚合的能力之后， RNC根据业务 的服务质量（QoS, Quality of Service )属性、 UE支持双频段非相邻载波聚 合的能力和 UE所处小区的支持双频段非相邻载波聚合的能力为 UE分配资 源。 具体的， RNC在根据 QoS属性、 UE支持双频段非相邻载波聚合的能 力和 UE当前所在小区的能力（主要是所支持的双频段非相邻载波聚合的能 力），在 UE支持双频段非相邻载波聚合、 小区支持双频段非相邻载波聚合， RNC也支持双频段非相邻载波聚合时， 确定配置给 UE的载波可以处于两 个不同的频段， 主辅载波之间、 辅载波与辅载波之间不需要是相邻的载波， 可以有其他载波的间隔。
步驟 303 , 网络侧向节点 B ( NodeB )发送无线链路建立请求消息或无 线链路重配请求消息， 该无线链路建立请求消息或无线链路重配请求消息 中携带网络侧配置的双频段非相邻载波多载波信息 （主要是辅载波小区信 息）。
步驟 304, 网络侧向 UE发送的无线承载建立消息或无线承载重配消息 或传输信道重配消息或物理信道重配消息， 该无线承载建立消息或无线承 载重配消息或传输信道重配消息或物理信道重配消息中携带网络侧配置的 双频段非相邻载波多载波信息。 该步驟可与步驟 303 并行执行； 步驟 303 及步驟 304并无严格的执行顺序。
本发明中， 多载波可以是双频段非相邻的多载波配置， 配置给 UE的载 波可以处于两个不同的频段， 主辅载波之间、 辅载波与辅载波之间不需要 是相邻的载波， 可以有其他载波的间隔。
本发明还记载了一种终端接入控制调整系统， 应用支持载波聚合的通 信系统中， 所述系统包括网络侧和 UE, 其中， 合能力组合列表以及支持的各个频段上支持非相邻载波聚合的能力信息通 知网络侧；
网络侧， 用于根据所述 UE 支持双频段非相邻载波聚合的能力和所述 UE所处小区的能力为 UE分配资源。
这里， UE支持的各个频段上支持非相邻载波聚合的能力信息可以是每 个频段组合中各个频段上支持非相邻载波聚合时的载波间最大间隔载波个 数， 但不限于载波间最大间隔载波个数。
本发明的终端接入控制调整系统还包括：
设置单元，用于在上行信道承载的消息中新增承载 UE支持的每个频段 组合中各个频段上支持非相邻载波聚合能力组合列表的信息单元 IE, 以及， 新增承载每个频段组合中各个频段上支持非相邻载波聚合时的载波间最大 间隔载波个数的 IE;
所述 UE进一步用于将所述上行信道承载的消息发送给所述网络侧。 上述上行信道 载的消息为 RRC Connection Setup Complete消息、 或 UE Capability Information消息。
上述网络侧进一步用于，根据 QoS属性、 UE支持双频段非相邻载波聚 合的能力和所述 UE所处小区的能力， 为所述 UE确定双频段多载波， 并通 知所述 UE。
综上所述，使得网络侧清楚准确获知 UE支持双频段非相邻载波聚合的 能力， 并依此合理分配资源。 以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
工业实用性
通过本发明， 网络侧接收到 UE上报的相邻载波支持的指示信息后， 即 可确定出 UE所能支持的多载波方式，从而便于网络侧根据 UE当前所在小 区的多载波支持能力， 为 UE进行多载波配置。
