反馈信息传输方法、 系统及设备
本申请要求于 2008 年 12 月 19 日提交中国专利局、 申请号为 200810239864.3、 发明名称为"反馈信息传输方法、 系统及设备"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， 具体涉及一种反馈信息传输方法、 系统及设备。 背景技术
HSUPA ( High Speed Uplink Packet Access, 高速上行链路分组接入）是 3GPP ( Third Generation Partnership Project, 第三代移动通信伙伴项目）提出 的一种上行增强方案，通过码道资源、 功率资源共享等策略以达到最大化上行 吞吐量。
HSUPA的数据传输分为调度传输与非调度传输。 调度传输的流程如图 1 所示：
a、 UE緩存中有上行增强数据等待发送， UE发送 E-RUCCH ( E-DCH Random access Uplink Control Channel, E-DCH随机接入上行控制信道），请求 调度资源；
b、 基站根据收到的调度请求信息进行资源调度， 并在 E-AGCH ( E-DCH Absolute Grant Channel, E-DCH绝对许可信道 )上发送资源许可信息；
c、 UE根据收到的资源调度信息， 进行增强传输格式组合（ E-TFC )选择， 选择合适的 TBS ( Transport Block Size, 传输块大小）和调制方式， 之后进行 编码、 调制， 在 E-PUCH ( E-DCH Physical Uplink Channel, E-DCH物理上行 信道）上发送上行增强数据；
d、基站收到 E-PUCH之后，进行解码处理，根据 CRC校验得到 ACK/NACK 信息，编码之后映射到 E-HICH( E-DCH HARQ acknowledge Indicator Channel, E-DCH HARQ应答指示信道 )上反馈给该 UE;
这样， UE就完成了一次调度传输过程的数据发送。
其中， 反馈的 E-HICH 物理信道由 E-AGCH 上的 2 比特 EI ( E-HICH Indicator, E-HICH指示）指示。 具体来说， 在数据传输前， 网络侧通过 RRC ( Radio Resource Control, 无线资源控制）信令为 UE配置最多四条 E-HICH, 并分别进行编号， 指示每一条 E-HICH的物理资源和训练序列 （midamble )分 配信息。基站通过 E-AGCH上的 EI指示该次传输将在四条中的哪一条 E-HICH 上反馈。
E-HICH上的 ACK/NACK编码方法为将 1比特的 ACK或者 NACK信息与 80比特长的正交序列异或。 其中， 正交序列由 E-PUCH所占用的物理资源以 及一个固定的随机化过程得到。 具体来说， 协议规定了一个 80阶的正交矩阵 C80 , 在 ACK/NACK编码时， 从该正交矩阵中取出某一行 80 比特长序列 (C80,r，,n), 其中， r，表示 80阶正交矩阵的第 r，行。 r，是由 r通过一个随机化过 程得到的。 r'= P(r, SFN', MidambkCode、， 其中 SFN，为 E-HICH的系统子帧号， MidambleCode为小区指定的基本 Midamble码序列， P为一个伪随机序列。
r为逻辑资源标签 ID , 与 E-PUCH所占物理资源存在映射关系：
/" = 16(。_1) + (¾τ。_1)^· 其中：
t。为分配时隙中的最后的时隙， 即最大时隙号 (1,2,..,5 )；
90为^。时隙内的最小信道化码号（1,2, ..., Qo);
Qo为 t。时隙最小信道化码号采用的扩频系数。
逻辑资源标签 ID与 E-PUCH所占物理资源的映射关系如图 2所示。
HSUPA中的非调度传输与调度传输不同， 不需要等待基站通过 E-AGCH 分配物理资源， E-PUCH资源预先由网络侧配置并通知 UE。 同时， 网络侧为 UE配置反馈的一条 E-HICH , 通知 UE该 E-HICH的物理资源和 midamble分 配以及所采用的签名序列组序号。 该签名序列组的序号 k取值范围为 0到 19。 每一组签名序列包括 4个正交序列， 为上述 80阶正交矩阵的第 4*k, 4*k+l, 4*k+2和 4*k+3行。 UE在网络侧分配的 E-PUCH上直接发送上行数据， 并在 配置的 E-HICH上接收基站的 ACK/NACK反馈和针对 E-PUCH信道的 TPC ( Transmit Power Control, 传输功率控制）和 SS ( Synchronisation Shift, 同步 偏移）。
此时， ACK/NACK和 TPC、 SS的编码采用如下方法：
将 80个正交序列分成 20组， 每组包括 4个具有连续逻辑资源标签 ID的 序列。 所述 80个正交序列即 80阶正交矩阵 C80, 与调度传输相同。 对于每个 非调度传输用户，高层会为其分配一组来表示 HARQ( Hybrid Automatic Repeat Request, 混合自动重传）应答指示 （ACK/NACK )和 TPC/SS命令。 四个序 列中的第一个码（逻辑资源标签 ID最小的码）用来表示 ACK/NACK消息， 其他三个序列中的一个用来隐含地表示 TPC/SS命令。
现有的 HSUPA技术中， 调度传输和非调度传输采用不同的 E-HICH, 即 小区内配置的 E-HICH 会被区分为调度类型的 E-HICH 和非调度类型的 E-HICH。 调度 E-HICH上只承载 ACK/NACK, 为某个用户的调度传输进行反 馈时，基站根据为该用户分配的调度 E-PUCH的物理资源确定编码时使用的正 交序列。 编码后在 EI所指示的那一条调度 E-HICH向该用户进行反馈。 而非 调度 E-HICH上除了承载 ACK/NACK以外，还承载了针对 E-PUCH的 TPC和 SS命令。 网络侧预先为每个非调度传输用户分配一条非调度 E-HICH以及一 个签名序列组。 当基站为某个用户的非调度传输进行反馈时，使用为该用户分 配的一组正交序列按照上述非调度传输时 ACK/NACK和 TPC、 SS的编码方 式进行编码， 并在该非调度 E-HICH上向该 UE进行反馈。
在 HSPA+ ( 3GPP HSPA 的增强技术） 的 CPC ( Continuous Packet Connectivity, 连续性分组连接 )研究中， 为了更好地支持 VoIP传输， 引入了 半持续调度的分配方法。即基站发送一次 E-AGCH为 UE分配半持续的物理资 源， 这些资源具有一定的重复周期。 之后， 基站也可以再次发送 E-AGCH调 整 UE的半持续资源分配。 在调整之前， UE可以在基站分配的半持续资源上 直接发送上行数据， 并在 E-HICH上接收反馈。 由于基站不再为每一次调度传 输发送 E-AGCH命令， 针对 E-PUCH的 TPC和 SS就需要承载在 E-HICH上。 所以， 需要按照非调度传输的方式进行反馈， 即网络侧预先为 UE配置反馈的 E-HICH物理资源以及一个签名序列组。
这种半持续调度的分配方法减少了控制信道开销， 一个小区可以采用半 持续资源分配方式支持更多的 VoIP用户。为了反馈 HARQ应答消息和 TPC、 SS, 需要为每个 VoIP用户预先配置一条非调度 E-HICH以及一个签名序列组， 并通 过 RRC信令通知 UE。 如果有 2个用户配置的是相同的 E-HICH以及相同的签名 序列组， 则基站不能在同一个 ΤΉ内同时调度这两个用户， 对调度灵活性造成 了限制。 而如果为每一个用户分配不同的签名序列组或者 E-HICH, 由于一条 非调度 E-HICH最多只有 20个码组， 当小区内的用户数大于 20时， 就必须至少 配置 2条非调度 E-HICH, 造成控制信道资源占用更大， 从而使得用来传输数据 的物理资源减少， 会影响系统的吞吐量。 发明内容

为了使本技术领域的人员更好地理解本发明实施例的方案，下面结合附图 和实施方式对本发明实施例作进一步的详细说明。
本发明实施例反馈信息传输方法， 由网络侧为用户分配调度传输类型的 行反馈时，按照非调度传输的反馈方式在所述调度传输类型的 E-HICH上承载 度传输的反馈信息在同一调度传输类型的 E-HICH上传输，使调度传输与非调 度传输共享调度传输类型的 E-HICH, 节省物理资源， 提高小区的吞吐量。
在按照非调度传输的反馈方式在所述调度传输类型的 E-HICH上承载对 应的反馈信息时， 需要确定非调度传输反馈所使用的签名序列组，在所述调度 码方式对所述信息进行编码。
由于在进行调度传输的反馈时，使用的签名序列与调度 E-PUCH物理资源 存在一定的映射关系。 时隙 1至时隙 5 , 每个时隙对应 16个正交序列， 共 80 个。 当系统支持较多 VoIP用户时， 由于该业务具有对称性， 所以上下行资源 的配置相对对称， 即除时隙 0外的 6个时隙， 不会出现上行或者下行占用 5 个时隙的情况。 RNC ( Radio Network Controller, 无线网络控制器）会为基站 配置 E-PUCH的资源池， 即调度和非调度 E-PUCH可以占用的物理资源， 典 型配置下一个小区内配置用作 E-PUCH的时隙会小于 5。在不改变调度传输的 反馈方式基础上， 调度传输 E-HICH上所需要的正交序列将小于 80, 为 16* 用作 E-PUCH的时隙个数。
本发明实施例的方法中， 利用这些空闲的正交码，作为非调度传输或者半 持续调度传输反馈时使用的签名序列组。 方式， 比如， 预先分配非调度签名序列组的方式， 或者还可以根据 E-PUCH 物理资源来确定。 当然， 本发明实施例对此不作限定， 还可以采用其他方式来 确定非调度传输反馈时使用的签名序列组。
下面结合不同的确定方式对本发明实施例进行详细说明。
参照图 3 , 是本发明实施例反馈信息传输方法的一种流程图， 包括： 步骤 301 , 网络侧为用户分配调度传输类型的 E-HICH并通知所述用户。 步骤 302, 根据小区内所有的 E-PUCH资源， 按照调度传输的反馈方式确 定对应的 E-HICH签名序列集合， 并按照非调度传输的反馈方式确定所述
E-HICH签名序列集合之外的签名序列对应的签名序列组集合。
步骤 303 , 从所述签名序列组集合中为所述用户分配一个签名序列组并通 知用户。
步骤 305,将编码后的反馈信息承载到所述调度传输类型的 E-HICH上传输。 例如， 小区中配置有 4个上行时隙， 分别为时隙 1至时隙 4, 下行为时隙 5和时隙 6。同时，将上行控制信道配置在时隙 1 ,时隙 2至时隙 4作为 E-PUCH 资源。 根据现有技术中调度传输时 HARQ应答响应的编码方式， 逻辑资源标 签 ID用 r表示， r可能的取值为 16到 63 , 共 48个正交序列。 而 r等于 0到 15以及 64到 79的 32个正交序列码不会被调度传输反馈所使用。 网络侧可以 将这些正交序列作为半持续调度传输的反馈，并将它们按照非调度传输的反馈 方式表示为一个签名序列组， 该组序号与正交序列的对应关系与现有技术相 同。 以本例来说， 签名序列组的序号可以为 0到 3以及 16到 19。
网络侧预先通过 RRC ( Radio Resource Control, 无线资源控制 )信令为用 户配置一条 E-HICH 和一个签名序列组。 该 E-HICH 为调度传输类型的 E-HICH,签名序列组为第 16组 (对应第 64至 67号码)。网络侧还可将该 E-HICH 分配给其它调度用户，也可以将第 0到 3组以及第 17至第 19组签名序列组分 配给其它的半持续调度或者非调度传输用户， 并为这些用户分配同样的一条 E-HICH。
当基站为该用户的半持续调度或者非调度传输进行反馈时，按照非调度传 输反馈的方式，使用第 64号正交序列表示 ACK或者 NACK,使用第 65至 67 中的一个正交序列表示 TPC和 ss。 这种反馈方式适用于该用户所有半持续调 进一步地， 当基站用一种新的 E-AGCH格式对该用户进行调度， 所述 E-AGCH上没有携带 EI, 且只为该用户分配了一个 ΤΉ ( Transmission Time Interval,传输时间间隔）的物理资源时， 这种情况可以看作半持续调度传输的 一种特例。在这种情况不下，基站可以在 E-HICH上只反馈 ACK或者 NACK, 使用的码字为第 64号码字， 而将 TPC和 SS承载在 E-AGCH上。
当基站使用该调度传输类型的 E-HICH为调度传输用户进行反馈时，利用 现有技术中的调度传输反馈方式， 根据 E-PUCH 的资源占用确定使用的正交 码， 并进行相应编码后在该调度传输类型的 E-HICH上反馈。
可见， 利用本发明实施例的方法， 在一条调度传输类型的 E-HICH不仅承 载了调度传输的反馈信息，而且还可以同时承载非调度传输或者半持续调度传 输的反馈信息， 从而有效地节省了物理资源。
例如，如果一个小区配置了 4个用作 E-PUCH的上行时隙、 3个下行时隙， 如果仅配置一条调度传输类型的 E-HICH和非调度传输类型的 E-HICH, 则可 以最多为 24个用户分配不同的正交码组，用非调度的反馈方式进行 HARQ应 答并反馈 TPC和 SS, 同时还可以支持调度传输的反馈要求。 如果一个小区配 置了 3个用作 E-PUCH的上行时隙、 4个下行时隙， 在同样的配置条件下， 利 用本发明实施例的方法则可以最多为 28个用户分配不同的正交码组， 用非调 度的反馈方式进行 HARQ应答并反馈 TPC和 SS,同时还可以支持调度传输的 反馈要求。
在该实施例中， 网络侧将确定的签名序列组通知用户， 这样， 所述用户就 可以根据所述签名序列组对接收的所述调度传输类型的 E-HICH进行解码，获 得对应的反馈信息。
当然， 对于用户来说， 是不区分接收的 E-HICH 是调度传输类型的
E-HICH, 还是非调度传输类型的 E-HICH或者半持续调度传输的 E-HICH, 因 此， 在应用本发明实施例的方法时， 用户只需要根据网络侧的通知在相应的 E-HICH上， 使用通知的所述签名序列组对接收的 E-HICH进行解码， 获得非 调度传输或者半持续调度传输的反馈信息。这样，可以更好地与现有技术兼容， 而且对现有设备也不需要大的改动， 有效地节省了设备成本。
参照图 4, 是本发明实施例反馈信息传输方法的另一种流程图， 包括： 步骤 401 , 网络侧为用户分配调度传输类型的 E-HICH并通知所述用户。 按照调度传输反馈时物理资源与正交序列的对应关系， 确定分配的 E-PUCH 物理资源对应的正交序列集合。
步骤 403 , 从所述正交序列集合中选择四个正交序列作为签名序列组。 步骤 404, 在所述调度传输类型的 E-HICH上使用所述签名序列组按照非 馈信息进行编码。
步骤 405 , 将编码后的反馈信息承载到所述调度传输类型的 E-HICH上传 输。
例如，限定半持续资源分配或者非调度传输时分配的码道扩频因子必须小 于等于 4, 即等效为 4个扩频因子为 16的虚码道。 当对该用户所有的半持续 调度传输以及所有的非调度传输进行反馈时，根据资源占用，按照调度传输反 馈时 E-PUCH物理资源与正交序列的对应关系确定相应的正交序列，由于限定 了扩频因子必须小于等于 4, 因此最少对应 4个正交序列。 如果资源对应的正 交序列大于 4个，那么网络侧可以从中选出 4个正交序列作为半持续调度或者 非调度传输反馈所使用的签名序列组。选取的规则可以预先定义或者由网络侧 决定并通知用户。 当基站为该用户的半持续调度或者非调度传输进行反馈时，按照非调度传 需要反馈的信息进行编码并反馈。
进一步地， 当基站用一种新的 E-AGCH格式对该用户进行调度， 所述 E-AGCH上没有携带 EI,且只为 UE分配了一个 ΤΉ的物理资源时，基站可以 在 E-HICH上只反馈 ACK或者 NACK, 将 TPC和 SS承载在 E-AGCH上。 用 来对 ACK/NACK编码的签名序列可以规定为签名序列组中序号最小的那一 个， 也可以由网络侧确定并通知 UE。
在该实施例中，网络侧按照调度传输反馈时 E-PUCH物理资源与正交序列 的对应关系，根据 E-PUCH物理资源确定对应的正交序列集合，并从中选择四 个正交序列作为签名序列组。在该实施例中， 网络侧无需将选择的四个正交序 列通知用户， 而是在网络侧和 UE侧分别根据 E-PUCH物理资源确定。 如果 E-PUCH物理资源对应的正交序列大于 4个，则可以由网络侧与用户预先约定 使用的 4个正交序列， 比如事先约定使用序号较小的 4个正交序列，或者网络 侧将选取规则通知 UE。 这样， 由用户按照调度传输反馈时物理资源与正交序 列的对应关系，确定分配的 E-PUCH物理资源对应的正交序列集合，然后按照 与网络侧约定的方式从所述正交序列集合中选择四个正交序列作为签名序列 组。 用户根据所述签名序列组对接收的所述调度传输类型的 E-HICH 进行解 码， 获得对应的反馈信息。
可见， 利用本发明实施例的方法， 在一条调度传输类型的 E-HICH不仅承 载了调度传输的反馈信息，而且还可以同时承载非调度传输或者半持续调度或 E-AGCH上没有承载 EI的调度传输的反馈信息。 对于非调度传输， 对应的反 馈信息包括： ACK或 NACK、 以及 TPC和 SS; 对于半持续调度传输， 如果 E-AGCH上未携带 EI信息， 并且为所述用户只分配了一个 ΤΉ的物理资源， 则所述对应的反馈信息包括： ACK或 NACK,否则对应的反馈信息包括： ACK 或 NACK、 以及 TPC和 SS。 从而有效地节省了物理资源， 提高了小区的吞吐 量。
当然， 对于用户来说， 是不区分接收的 E-HICH 是调度传输类型的 E-HICH, 还是非调度传输类型的 E-HICH或者半持续调度传输的 E-HICH, 因 此，在应用本发明实施例的方法时， 用户可以根据系统的约定或者根据网络侧 的通知来决定在半持续调度或者非调度传输时， 在接收到 E-HICH后， 是否要 确定签名序列组， 并根据所述签名序列组对接收的 E-HICH进行解码， 获得非 调度传输或者半持续调度传输的反馈信息。这样，可以更好地与现有技术兼容， 而且对现有设备也不需要大的改动， 有效地节省了设备成本。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤 是可以通过程序来指令相关的硬件来完成，所述的程序可以存储于一计算机可 读取存储介质中， 所述的存储介质， 如： ROM/RAM、 磁碟、 光盘等。
本发明实施例还提供了一种反馈信息传输系统， 如图 5所示，是该系统的 一种结构示意图。
该系统包括： 信道分配单元 501和反馈信息发送单元 502。
其中， 信道分配单元 501 , 用于为用户分配调度传输类型的 E-HICH并通 知所述用户； 反馈信息发送单元 502, 用于为所述用户的非调度传输或者半持 续调度传输进行反馈时， 按照非调度传输的反馈方式在所述调度传输类型的 E-HICH上承载对应的反馈信息。

当然， 本发明实施例的反馈信息传输系统中， 所述签名序列组确定单元
503并不仅限于上述这两种结构方式， 根据实际应用环境， 还可以有其他实现 方式。
本发明实施例的系统， 在进行非调度传输或者半持续调度传输时， 可以将 相应的反馈信息承载在一条调度传输类型的 E-HICH上，实现调度传输与非调 度传输反馈信息对 E-HICH的共享， 从而有效地节省了物理资源， 提高小区的 吞吐量。 及所有的非调度传输方式的反馈。 进一步地， 当基站用一种新的 E-AGCH格 式对该用户进行调度， 所述 E-AGCH上没有携带 EI, 且只为 UE分配了一个 TTI的物理资源时， 基站可以在 E-HICH上只反馈 ACK或者 NACK, 将 TPC 和 SS承载在 E-AGCH上。 也就是说对于非调度传输， 所述调度传输类型的 E-HICH上承载的反馈信息包括： ACK或 NACK、 以及 TPC和 SS; 对于半持 续调度传输， 如果 E-AGCH上未携带 EI信息， 并且为所述用户只分配了一个 TTI的物理资源，则所述调度传输类型的 E-HICH上承载的反馈信息包括： ACK 或 NACK, 否则对应的反馈信息包括： ACK或 NACK、 以及 TPC和 SS。
