Description

一种数据传输方法和系统 本申请要求于 2010 年 09 月 28 日提交中国专利局、 申请号为 201010294643.3、 发明名称为 "一种数据传输方法和系统" 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 本发明涉及通信领域, 尤其涉及一种数据传输方法和系统。 背景技术 无线通信系统被广泛部署以提供各种通信服务, 例如, 可经由这样的 无线通信系统提供语音、 视频、 分组数据、 广播和消息接发服务。 这些通 信系统可以是能够通过共享可用的系统资源来支持多个终端通信的多址通 信系统。 此类多址通信系统的示例包括码分多址( CDMA , Code Division Multiple Access ) 系统、 时分多址 ( TDM A, Time Division Multiple Access ) 系统、 频分多址 ( FDMA, Frequency Division Multiple Addressing ) 系统、 以及正交频分多址 ( OFDMA , Orthogonal Frequency-Division Multiple Access ) 系统。
一般而言, 无线多址通信系统可以同时支持多个无线终端。 在这样的 通信系统中, 每一终端可经由前向或反向链路上的传输与一个或多个基站 通信。 前向链路(或即下行链路)是指从基站至终端的通信链路, 而反向 链路(或即上下链路)是指从终端至基站的通信链路。 这种通信链路可经 由单入单出 (SISO , Single-Input Single- Output )、 多入多出 ( MISO , Multiple-Input Single-Output )、 或多入多 出 ( MIMO , Multiple-Input Multiple-Output ) 系统建立。 例如, 目前的通用分组无线业务 ( GPRS, General Packet Radio Service ) 系统中, 一个移动台 (MS, Mobile Station )只能在一个载频上进行下行数 据接收, 且工作带宽为 200KHz, 这样显然限制了数据的传输速率。 比如: 基于这种数据接收方案,在目前的全球移动通信系统(GSM, Global System for Mobile communications )演进增强数据速率无线接入网( EGRPS, GSM EDGE Radio Acesss Network )系统下, 即使为一个载频分配 4个时隙, 这 4 个时隙的实际速率也不到 200kbps。 而随着数据类业务的发展, 现有速率已 不能满足用户的需求。
再例如, 在宽带码分多址( WCDMA, Wideband Code Division Multiple Access Wireless ) 系统中, 随着用户数量的增多, 现有网络可能无法承担其 业务量, 出现网络拥塞, 数据业务与语音业务的资源竟争时, 也可能影响 网络的通信性能。
鉴于上述情况, 一些通讯设备厂商提出了一个新的数据传输方案, 即 下行双载频 /多载频传输。 顾名思义, 下行双载频是指一个 MS可以在两个 载频上同时进行下行数据接收; 下行多载频是指一个 MS 可以在多个(例 如, 至少三个)载频上同时进行下行数据接收。 下行双载频 /多载频传输突 破通信系统一直沿袭的带宽限制, 使得一个 MS 可以在一个以上的载频上 同时进行下行数据接收。 设用于接收下行数据的载频数为 N, 则这种传输 方案可以使工作带宽变为 200xN KHz, 相应的数据传输速率也根据载频数 成比例地提高。 仍然以目前的 EGRPS系统为例, 一个载频分配 4个时隙的 实际速率为 200kbps,而如果 MS能够在 5个载频上同时进行下行数据接收, 则速率可以接近 lMkbps, 完全能够满足 3G系统对速率的要求。
由以上描述可以看出, 引入下行双载频 /多载频传输方案, 可以对通信 系统进行很好的扩容和提高通信质量, 且该方案只需要在现有系统的基础 上进行筒单的升级就可以极大地提高下行数据传输速率。 该方案既节约了 运营商在设备上的投资, 又能满足新业务的开展, 在通信系统中有广泛的 应用前景。
在多载频 WCDMA系统中, 用户设备 ( UE, User Equipment ) 同一时 刻与多个载频的 WCDMA小区同时工作, 这个过程可以称为载频调度或小 区调度, 极大提高了同一 UE的下行和上行数据传输速率。 同时, 多个载频 的互操作使多载频小区之间的快速动态负载平衡成为可能。 这种快速动态 负载平衡可以提高原 WCDMA小区的吞吐率及提高对用户响应的及时性。
UE有两种基本运行模式: 空闲模式和连接模式。
空闲模式, 只有一种 Idle状态, 是指用户设备处于待机状态, 尚无业 务存在时的状态。 UE开机后停留在空闲模式下。
连接模式,是指用户设备与无线网络控制器( Radio Network Controller, RNC )之间已经完成无线资源控制( Radio Resource Control, RRC )连接建 立时的状态, 此时, 用户设备已驻扎在一个小区中。 UE连接模式共有四种 状态: CELL_DCH (小区 _专用信道)、 CELL_FACH (小区 _前向接入信道)、 CELL_PCH (小区 _寻呼信道)、 URA_PCH (通用陆地无线接入网注册区域 _寻呼信道)状态。 当 UE 完成 RRC 连接建立后, 才会从空闲模式转移 到连接模式, CELL-FACH或 CELL-DCH。 当 RRC连接释放后 UE从连 接模式到空闲模式。
CELL_DCH 状态: 用户设备具有专用控制信道(DCCH, Dedicated Control Channel )和专用业务信道( DTCH, Dedicated Traffic Channel ), 并 利用专用 (或共享)信道进行通信过程的状态。 Cell-DCH适用场景: 连续 或大量的数据传输, 如打电话、 下载。
CELL_FACH状态: 用户设备具有 DCCH和 DTCH, 可以在前向接入 信道(FACH, Forward Access Channel ) 上接收数据和在随机接入信道 ( RACH, Random Access Channel )上发送数据, 无需分配专用信道, 在公 共 FACH/RACH信道上传递消息的状态。 Cdl-FACH适用场景: 少量的数 据传输, 如信令、 短消息。 CELL_PCH状态: 用户设备不能够使用 DCCH和 DTCH, 不可以接收 和发送数据, 只在下行方向侦听寻呼指示信道 (PICH , Page Indicator Channel )上的寻呼指示消息时的状态;只可以发送小区更新( CELL Update ) 消息到 RNC。 Cdl-PCH适用场景: 非连续业务(如网页浏览)且 UE移动 速度比较慢, 例如在固定区域的用户。
URA_PCH状态: 用户设备不能够使用 DCCH和 DTCH, 不可以接收 和发送数据, 只在下行方向侦听 PICH信道上的寻呼指示消息时的状态; 只 可以发送用户注册区更新 ( URA Update ) 或 Cell Update 消息到 RNC。
URA-PCH适用场景: 非连续业务, 且 UE移动速度比较快, 例如乘坐交通 工具的用户。
但目前的双载频 /多载频技术并不能应用于 CELL_FACH状态下的 UE, 则 CELL_FACH状态下的 UE并不能享受多载频带来的增益。 发明内容

5Mhz、 10Mhz、 15Mhz等等, 低频覆盖的范围较大, 高频覆盖的范围较小, 因此, 两个载频的覆盖程度可能是完全覆盖, 也可能是部分覆盖。

通过上述的描述可知, 上述方案可以使得 CELL_FACH状态下的 UE 通过双载频 /多载频传输数据, 提高数据的传输速率和可靠度。
例如, 如图 6所示, 为本发明另一实施例的一种扩展后的高速下行链 路共享信道数据帧类型 2 ( HS-DSCH DATA FRAME TYPE 2 ) 的数据结构 示意图。
如图 6所示, 扩展后, 通过新 IE指示( New Flags IE ) 中 bit 2指示是 否存在配对小区标识( Paired Cell ID )。 如果 bit2设置为 1表示存在, 设置 为 0表示不存在, 反之亦然。
如果 New Flags IE指示存在配对 、区标识, Paired Cell ID可以在高速 下行链路共享信道物理层类型 ( HS-DSCH physical layer category )信元之 后存放, 最前面两个 bit表示配对载频的数量(Cell Num ), 如果系统规定 只有一个配对载频, 则此字段可以不存在。 后面接着存放每个配对载频的 小区标识 ( cell ID ), 其中的 cell ID可以是对应于本地小区标识 ( local cell id ), 或者小区建立中的小区标识(Cell ID ), 或者是对应于上报的可能配对 邻区的索引,每个 cell ID占 N bit,其中 N可能是( 4 - 32 )之间的值。 Paired Cell ID(cont)表示还可以有至少多个配对 d、区标识。

通过上述的描述可知, 上述方案可以使得 CELL_FACH状态下的 UE 通过双载频 /多载频传输数据, 提高数据的传输速率。
如图 7所示, 为本发明另一实施例的一种数据传输方法的流程示意图, 该数据传输方法可以如下所述。
701 , UE通过无线资源控制( RRC, Radio Resource Control )消息上 4艮 UE支持 Cell FACH双载频 /多载频的能力信息。
该 RRC消息可以是无线资源控制连接请求( RRC Connection Request ) 消息或者无线资源控制连接建立完成( RRC Connection Setup Complete )消 息等。
702, 基站控制器获取 UE支持 Cell FACH双载频 /多载频的能力信息, 根据 UE的能力信息配置 UE工作于 Cell FACH双载频 /多载频。
例如, RNC获取 UE支持 Cdl FACH双载频 /多载频的能力信息, 根据 该能力信息是 True或 false的值, 决定是否启用此 UE在 Cell FACH下进行 双载频 /多载频传输,配置所述用户设备工作于 CELL_FACH的双载频 /多载 频的配置信息。
703, 基站控制器向 UE发送 UE支持 Cell FACH双载频 /多载频的配置 信息。
通过 RRC 消息, 基站控制器通过基站向用户设备发送 UE 支持 CELL_FACH双载频 /多载频的配置信息, 并通过 RRC消息配置给 UE配对 辅载频的配置信息, 例如, 所述辅载频配置信息包括辅载频 HS - SCCH信 道的参数, 辅载频最高调制方式等参数, 一个小区, 只有一个主频点, 可 以有至少一个配对的辅频点。 该 RRC 消息可以是 RRC 连接建立 (RRC CONNECTION SETUP ), 无线 载建立 ( RB Setup ) 消息或无线 载重配 置 ( RB reconfiguration )等消息。
704, UE 向基站控制器发送配置响应消息。
UE在双载频 /多载频传输配置响应的 RRC消息中确认配置成功, 该响 应消息根据 702中选取的消息不同而不同,例如,如果 702中是在 RB setup 消息中配置 UE支持 CELL_FACH双载频 /多载频, 则确认消息为无线建立 完成( RB setup complete )消息,如果 702中是在 RRC CONNECTION SETUP 消息中配置 UE支持 CELL_FACH双载频 /多载频,则确认消息为 RRC连接 建立完成( RRC CONNECTION SETUP COMPLETE )消息, 依次类推。 进 一步, 所述配置响应消息可以携带对辅载频信号强度或信号质量的初始测 量结果。
705, 基站控制器在收到配置响应之后通过 FP帧携带双载频 /多载频工 作参数发送给基站。
例如,所述基站控制器将所述双载频 /多载频工作参数携带在 FP帧的高 速下行链路共享信道数据帧类型 2 ( HS-DSCH DATA FRAME TYPE 2 ) 中 发送给所述基站。 所述双载频 /多载频工作参数包括新 IE指示 (New Flags IE ),用于指示是否存在配对小区信息,如果所述新 IE指示指示存在配对小 区信息, 所述双载频 /多载频工作参数还包括配对小区信息。 配对小区信息 的具体携带方式, 可以参考前述图 6所述。
在本发明的另一实施例中, 如果双载频 /多载频工作参数包含配对小区 信息, 所述双载频 /多载频工作参数还包括配对小区个数和 /或高速共享信道 无线网络临时标识( H-RNTI )和/或对辅载频小区信号强度或质量测量结果。 在本发明的另一实施例中, 如果双载频 /多载频工作参数包含配对小区 信息, 所述配对小区信息为配对小区标识或配对小区标识在可协作邻区列 表中的索引, 其中, 所述可协作邻区列表包括同频段的可协作列表和异频 段的可协作列表。
例如,基站控制器在收到配置响应之后在第一下行 FP帧中开始携带配 对小区号及辅载频 H-RNTI信息给基站。
例如, 基站控制器决定对此用户在双载频 /多载频上发送下行数据, 将 携带配对小区信息的下行用户数据 (例如^载在 FP帧 )发送给基站, 其中 配对小区可以是一个或多个, 配对小区的信息可以是小区 ID。 小区 ID可以 是 16位, 携带在 FP帧中, 也可以通过进一步优化, 携带小区在可配对邻 区列表中的索引, 例如, 优化方案可以如下所述。
双载频 /多载频技术中, 基站向基站控制器上报可能进行配对的邻区列 表。 基站控制器根据可能的配对邻区最终决定配对关系, 比如基站上报可 以和本小区 (例如 local cdl ID = 0 )进行配对的小区列表为 2, 3, 4。 则基 站控制器可能进行配置的双载频 /多载频小区配对为: (0, 2 ), ( 0, 3 ), ( 0, 4 ), 或 (0, 2, 3 ), 或 (0, 2, 3, 4 )等。 目前可能的邻区最多为 32个, 二进制编码占 5 比特。 基站控制器可以利用邻区列表中的索引指指定配对 小区信息, 指定一个配对小区信息相对于 16bit的 cell Id可以节省 libit的 开销, 指定 3个时可以节省 33bit的开销。 例如, 基站在邻频可协作邻区列 表中上报 3个可协作邻区,则基站控制器在 FP帧中携带配对小区信息时可 以指定可第几个可协作邻区进行配对, 而不需要携带这个邻区的 Cdl ID。
706, 基站根据 FP帧中小区配对信息决定在那些小区上调度该 UE。 基站根据用户数据中携带的小区配对信息, 决定下行数据从那些配对 小区上进行调度。
通过上述的描述可知, 上述方案可以使得 CELL_FACH状态下的 UE 通过双载频 /多载频传输数据, 提高数据的传输速率和可靠度。 如图 8所示, 为本发明另一实施例的一种数据传输方法的流程示意图, 该数据传输方法可以如下所述。
为使 UE在没有接收到双载频 /多载频配置信息之前, 也能以双载频 /多 载频方式进行数据传输, 例如, set up RRC连接, 可以在双载频发送, 比较 快, 可靠性好, 有利于进一步提高数据传输速度, 本实施例提供的技术方 案可以使得 UE可以双载频 /多载频的方式接收双载频 /多载频配置信息。
801 , 广播预配对小区信息。
例如, 基站控制器在小区建立或物理共享信道重配中指定该小区的预 配对小区信息, 例如, 本小区标识( local cell ID )为 0, 该本小区的预配对 小区信息为: (0, 2 ), ( 0, 3 )。 广播时, 基站控制器向基站广播配置的预 配对小区信息。
802, UE接收所在小区的广播消息获得辅小区和辅小区的 CELL_FACH 资源。
基站控制器通过基站, 在系统信息广播中将本小区的预配对小区信息 发送给用户设备, 此预配对小区信息中包含预配对小区的小区标识或小区 索引, 还可以包含预配对小区的公共信令承载的配置等。 UE获得广播消息 携带的辅小区和辅小区的 CELL_FACH资源。
803, 上报 UE支持 Cdl_FACH双载频 /多载频的能力信息。
UE读取系统信息广播后, 向基站控制器发送连接建立请求,例如 RRC CONNECTION REQUEST ,其中携带 UE支持 Cell_FACH双载频 /多载频的 能力信息。 在本发明的另一实施例中, 所述连接建立请求还可以携带主辅 小区的 RACH测量值, 例如, 对当前本小区 (也即主小区)和预配对小区 的初始信号强度或质量测量结果。
804,重新配置的 UE支持 Cell_FACH双载频 /多载频的配置信息并发送 给 UE。
例如, 基站控制器根据收到的 UE支持 Cdl_FACH双载频 /多载频的能 力信息, 重新配置的 UE支持 Cdl_FACH双载频 /多载频的配置信息。 并将 所述 UE支持 Cdl_FACH双载频 /多载频的配置信息通过基站发送给 UE, 例如, 通过 RB setup消息或 RRC CONNECTION SETUP发送, 其中在发送 给基站时携带指示, 用于指示所述 UE支持 Cdl_FACH双载频 /多载频的配 置信息可以通过预配对的小区进行调度。 例如, 指定方式可以是通过在帧 协议中定一个新的比特位来指示,如果该比特被设置为 true,指示基站可以 通过 801 中预配对的小区对进行调度, 或者在用户数据中携带重新配置的 配对小区信息, 其中配对小区信息的实现方式可以参考前述图 7的实施例, 在此不再赘述。 所述重新配置的配对小区可以与预配对小区相同, 也可以 不同, 或者部分相同。 例如, 如果预配对小区为 (0, 2 ), ( 0, 3 ), 则重新 配置的配对小区可以为 (0, 2 ), ( 0, 3 ), 也可以为 (0, 2 ), ( 0, 4 ), 或 为 (0, 4 ), ( 0, 5 )。
基站根据所述指示将所述 UE支持 Cdl_FACH双载频 /多载频的配置信 息通过预配对的多载频发送给 UE。
805, UE 向基站控制器发送配置响应消息。
UE在双载频 /多载频传输配置响应的 RRC消息中确认配置成功, 该响 应消息根据 804中选取的消息不同而不同,例如,如果 804中是在 RB setup 消息中配置 UE支持 CELL_FACH双载频 /多载频, 则确认消息为无线建立 完成( RB setup complete )消息,如果 804中是在 RRC CONNECTION SETUP 消息中配置 UE支持 CELL_FACH双载频 /多载频,则确认消息为 RRC连接 建立完成( RRC CONNECTION SETUP COMPLETE )消息, 依次类推。 进 一步, 所述配置响应消息可以携带对辅载频信号强度或信号质量的初始测 量结果。
806, 基站控制器在收到配置响应之后通过 FP帧携带双载频 /多载频工 作参数并发送给基站。
例如,所述基站控制器将所述双载频 /多载频工作参数携带在 FP帧的高 速下行链路共享信道数据帧类型 2 ( HS-DSCH DATA FRAME TYPE 2 ) 中 发送给所述基站。 所述双载频 /多载频工作参数包括新 IE指示 (New Flags IE ),用于指示是否存在配对小区信息,如果所述新 IE指示指示存在配对小 区信息, 所述双载频 /多载频工作参数还包括配对小区信息。 配对小区信息 的具体携带方式, 可以参考前述图 6所述。
在本发明的另一实施例中, 如果双载频 /多载频工作参数包含配对小区 信息, 所述双载频 /多载频工作参数还包括配对小区个数和 /或高速共享信道 无线网络临时标识( H-RNTI )和/或对辅载频小区信号强度或质量测量结果。
在本发明的另一实施例中, 如果双载频 /多载频工作参数包含配对小区 信息, 所述配对小区信息为配对小区标识或配对小区标识在可协作邻区列 段的可协作列表。
例如,基站控制器在收到配置响应之后在第一下行 FP帧中开始携带配 对小区号及辅载频 H-RNTI信息给基站。
例如, 基站控制器决定对此用户在双载频 /多载频上发送下行数据, 将 携带配对小区信息的下行用户数据 (例如^载在 FP帧 )发送给基站, 其中 配对小区可以是一个或多个, 配对小区的信息可以是小区 ID。 小区 ID可以 是 16位, 携带在 FP帧中, 也可以通过进一步优化, 携带小区在可配对邻 区列表中的索引, 例如, 优化方案可以如下所述。
双载频 /多载频技术中, 基站向基站控制器上报可能进行配对的邻区列 表。 基站控制器根据可能的配对邻区最终决定配对关系, 比如基站上报可 以和本小区 (例如 local cdl ID = 0 )进行配对的小区列表为 2, 3, 4。 则基 站控制器可能进行配置的双载频 /多载频小区配对为: (0, 2 ), ( 0, 3 ), ( 0, 4 ), 或 (0, 2, 3 ), 或 (0, 2, 3, 4 )等。 目前可能的邻区最多为 32个, 二进制编码占 5 比特。 基站控制器可以利用邻区列表中的索引指指定配对 小区信息, 指定一个配对小区信息相对于 16bit的 cell Id可以节省 libit的 开销, 指定 3个时可以节省 33bit的开销。 例如, 基站在邻频可协作邻区列 表中上报 3个可协作邻区,则基站控制器在 FP帧中携带配对小区信息时可 以指定可第几个可协作邻区进行配对, 而不需要携带这个邻区的 Cell ID。 如果基站上报的可写作邻区列表多于一个, 比如上报邻频可协作邻区列表 以及跨频段可协作小区列表, 则基站控制器在指定在可协作邻区列表中的 索引的同时还需要指定对应的是那个邻区列表, 例如, 如果可协作邻区列 表多于一个, 在 FP中指示小区标识在可协作邻区列表中的索引的同时, 还 在 FP中进一步指定可协作邻区列表的标识。比如 0代表邻频可协作邻区列, 1代表跨频段可协作小区列表,基站控制器想指定配对小区为邻频可协作类 标中的第 2个小区,则在 FP帧中发送的二进制的 000001 ,其中最左边一位 0代表邻区列表为邻频可协作邻区列表,右边 00001代表邻频可写作邻区列 表中的第 2个个小区。
807,基站根据 FP帧中新的小区配对信息决定在那些小区上调度该 UE。 基站根据用户数据中携带的小区配对信息, 决定下行数据从那些配对 小区上进行调度。
通过上述的描述可知, 上述方案可以使得 CELL_FACH状态下的 UE 通过双载频 /多载频传输数据, 提高数据的传输速率。
