具体实施方式 为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本 发明实施方式作进一步地详细描述。
载波聚合场景下， eNB会通过半静态 RRC ( Radio Resource Control, 无线资源控制）信令给 LTE-A用户设备配置或重配置一个可以调度的载波 集合， 例如 UE DL CC set( User Equipment Downlink Component Carrier Set, 用户下行成员载波集合)。 同时， 为了省电， 在半静态配置的 UE DL CC set 的基础上引入了载波激活 （即开启） /去激活 （即关闭）机制， 除了下行主 载波外，其他成员载波均可根据业务需求进行激活或去激活。如果 UE( User Equipment, 用户设备） 当前业务速率增加， eNB可以激活 UE DL CC set 中未被激活的某个或某几个载波来进行数据传输；如果 UE当前业务速率降 低， eNB可以去激活 UE DL CC set中除下行主载波外的某个或某几个已激 活的载波。 激活 /去激活通过 MAC ( Medium Access Control ， 媒质接入控 制）层信令完成，每条 MAC层载波激活 /去激活信令可激活或去激活 UE DL CC set中除主载波外的一个或多个载波。 eNB下发了 MAC层信令后可通过 ACK/NACK反馈获知激活 /去激活信令是否传输成功。针对去激活信令， 又 进一步引入了隐式去激活的机制进行优化， 即引入隐式去激活定时器， 以 某次接收为基准启动该定时器， 若该定时器的定时时间到达， 则去激活相 应的载波。
同时在 LTE-A系统中，为了支持动态调度、下行的 MIMO( Multiple Input Multiple Output, 多输入多输出）传输及混合自动重传等技术， UE需通过 PUCCH( Physical Uplink Control Channel,物理上行控制信道）或/和 PUSCH ( Physical Uplink Share Channel,物理上行共享信道 )向 eNB传输下行载波 的 UCI, 且在载波聚合场景下 UE需要向 eNB传输多个下行载波的 UCI。 LTE-A系统中， UE需要传输的 UCI通常包括 CSI( Channel State Information, 信道状态信息）和 HARQ ( Hybrid Automatic Repeat request, 混合自动重 传请求）确认信息（ ACK ( Acknowledgment， 确认应答） /NACK ( Negative Acknowledgement, 否认应答））。其中 CSI通常又包括 CQI( Channel Quality Information,信道质量信息 )、 RI ( Rank Indication,秩指示 )、 PMI ( Precoding Matrix Indicator, 预编码矩阵指示）等隐式信道状态信息， 以及信道矩阵 或信道协方差矩阵等直接信道状态信息。
目前在载波聚合场景下，当多个下行载波的 ACK/NACK或 CSI在一个 PUCCH或一个 PUSCH上传输时，通常 UE需对多个下行载波的 ACK/NACK 或 CSI进行联合信道编码， eNB根据 UE采用的信道编码方法进行译码。
eNB译码时， 需要知道 UE 釆用的 UCI ( Uplink Control Information, 上行控制信息）联合信道编码的总原始信息比特数， 即需要保证 eNB和 UE 对多个下行载波的 UCI联合编码的总原始信息比特数的理解一致， 才能进 行正确的译码。 但是， 采用目前存在的传输 UCI的方法， 导致 eNB对联合 编码的 UCI译码错误。
参见图 1， 本发明实施例提供了一种传输上行控制信息的方法， 包括：
101 :用户设备按照预设的排序规则对 X个下行载波中每个下行载波的 上行控制信息 UCI进行排序； 其中， X为正整数， X个下行载波属于用户 设备的下行成员载波集合， 用户设备的下行成员载波集合至少包括两个下 行成员载波， 且 X个下行载波中至少一个下行载波属于用户设备的下行激 活载波集合。

UCI进行排序。

进一步地， 当 X个下行载波的 UCI与调度请求 SR在同一个子帧上报 时， 预设的排序规则为： 按照先排列 SR， 再按照下行载波被激活的先后顺 序将 X个下行载波中每个下行载波的 UCI依次排列在 SR的后面的顺序进 行排序。
进一步地， 当按照下行载波被激活的先后顺序对 X个下行载波中每个 下行载波的 UCI进行排序时， 如果有多个下行载波同时被激活， 则按照每 个下行载波的属性对同时被激活的多个下行载波的 UCI进行排序。
进一步地， 下行载波的属性为载波索引或载波频率。

进一步地， 当预设的排序规则为按照下行载波被激活的先后顺序进行 排序时， 如果有多个下行载波同时被激活， 则按照每个下行载波的属性递 增或递减的顺序对同时被激活的多个下行载波的 UCI进行排序。

本发明实施例所述的传输上行控制信息的方法， 基站通过根据第一载 波集合得到 UCI占用的调制符号个数， 根据 UCI占用的调制符号个数提取 用户设备传输的 UCI及得到传输的 UCI对应的信道编码后的比特数， 解决 了基站和用户设备对多个下行载波的 UCI的联合编码的总的原始信息比特 数理解不一致导致基站对联合编码的 UCI译码错误的问题； 并且， 基站根 据预设的排序规则可以确定出与每个下行载波对应的 UCI。 本发明实施例提供了另一种传输上行控制信息的方法， 包括： 根据预设的上行控制信息 UCI对应的信道编码后的比特数， 对用户设 备传输的 UCI进行检测 ， 并根据预设的排序规则， 确定与每个下行载波对 应的 UCI。 进一步地， 预设的排序规则为按照下行载波被激活的先后顺序进行排 序， 且如果有多个下行载波同时被激活， 则按照每个下行载波的属性递增 或递减的顺序对同时被激活的多个下行载波的 UCI进行排序的顺序。
进一步地， 当用户设备的 UCI与调度请求 SR在同一个子帧上报时， 根据预设的排序规则， 确定与每个下行载波对应的 UCI, 具体为：
根据先排列 SR，再按照下行载波被激活的先后顺序将 X个下行载波的 UCI依次排列在 SR 的后面的顺序， 确定出 SR及与每个下行载波对应的 UCI, X为正整数。
本发明实施例所述的传输上行控制信息的方法， 基站根据预设的上行 控制信息 UCI对应的信道编码后的比特数， 对用户设备传输的 UCI进行检 测， 解决了基站和用户设备对多个下行载波的 UCI的联合编码的总的原始 信息比特数理解不一致导致基站对联合编码的 UCI译码错误的问题；并且， 基站根据预设的排序规则可以确定出与每个下行载波对应的 UCI。 为了便于理解本发明实施例，下面以本发明实施例所述的方法应用于载 波聚合场景下， 在一个 PUSCH上传输大于等于 1个下行载波的 ACK/NACK 为例， 进行进一步地说明。 参见图 4，本发明实施例提供了另一种传输上行控制信息的方法，包括：
401 : UE 按照预设的排序规则对 X 个下行载波中每个下行载波的 ACK/NAC 进行排序， 其中， X为正整数， X个下行载波属于 UE的下行 成员载波集合， 用户设备的下行成员载波集合至少包括两个下行成员载波， 且 X个下行载波中至少一个下行载波属于用户设备的下行激活载波集合， 且此处 X个下行载波为 UE的下行载波集合中的所有下行载波。
其中， 预设的排序规则可以为按照下行载波被激活的先后顺序进行排 序， 并且当有多个下行载波同时被激活时， 可以按照每个下行载波的 ACK/NAC 对应的下行载波的属性对同时被激活的多个下行载波的 ACK/NAC 进行排序，下行载波的属性可以是下行载波的载波索引（ Carrier Index/Carrier Identity )或载波频率， 具体可以按照下行载波的属性的递增或 递减的顺序对同时被激活的多个下行载波的 ACK/NACK进行排序。
具体地，对 X个下行载波中的每个下行载波：若需要反馈 ACK/NACK, 且 ACK/NACK支持空间捆绑（ spatial bundling )， 则每个下行载波对应 1比 特 ACK或 NACK; 若需要反馈 ACK/NACK,且 ACK/NACK不支持空间捆 绑，则每个下行载波对应 2比特 ACK或 NAC ：。若不需要反馈 ACK/NACK, 且 ACK/NACK支持空间捆绑， 则每个下行载波对应 1比特 NACK; 若不需 要反馈 ACK/NACK， 且 ACK/NACK不支持空间捆绑， 则每个下行载波对 应 2比特 NACK。所谓需要反馈 ACK/NACK是指在该载波上检测到需要反 馈 ACK/NACK 的信息， 如数据或指示释放下行 SPS ( Semi-Persistent Scheduling , 半持续调度） 资源的 PDCCH ( Physical Downlink Control Channel, 物理下行控制信道）信令。
UE根据上述方法确定 X个下行载波中的每个下行载波的 ACK/NACK 的原始信息，使得 X个下行载波中的总的原始信息比特数 为： oACK = X 或 0^ =2；^。 X 对应 ACK/NACK 支持空间捆绑时的场景， 2X 对应 ACK/NAC 不支持空间捆绑时的场景。
402: UE根据第一载波集合（CC Set ), 计算 UE的 ACK/NACK占用 的调制符号个数 ( coded symbols或 modulation symbols )。
其中， 第一载波集合可以为用户设备的下行成员载波集合 （User Equipment Downlink Component Carrier Set )， 或可以为 UE可支持的最大下 行载波集合，或可以为用户设备的下行成员载波集合和 UE可支持的最大下 行载波集合二者中的较小者。 具体地， 根据第一载波集合， 利用公式 （ 1 ) 计算得到用户设备的 ACK/NACK占用的调制符号个数。
Q' = min
Figure imgf000014_0001
其中， β'表示用户设备的 ACK/NACK占用的调制符号个数； 0表示第 一载波集合对应的所有 ACK/NACK的总的信息比特数， 当每个下行载波的 ACK/NAC 支持空间捆绑时 ( = M，当每个下行载波的 ACK/NACK不支持 空间捆绑时 0 = 2M， M表示第一载波集合中包括的载波的个数； N er表示 ACK/NACK映射到的码字对应的总层数； M^CH-M,ial表示同一个传输块初传 时 PUSCH的传输带宽； 表示当前子帧对应的 PUSCH的传输带宽； N™ H-initial表示同一个传输块初传时所占的 SC-FDMA(Single Carrier Frequency Division Multiple Access , 单载波频分多址)符号的个数； β Η表 示 ACK/NACK相对于数据 MCS ( Modulation and Coding Scheme 调制编码 方案） 的偏移， β Η = β:？- ACK ' 其中 的取值由高层 RRC ( Radio Resource Control, 无线资源控制）信令通知； C表示码块的个数； 为第 r 个码块的信息比特数与 CRC ( Cyclical Redundancy Check ,循环冗余码校验 ) 校验比特数之和。
403 : UE根据 UE的 ACK/NACK 占用的调制符号个数， 计算 UE的 ACK/NAC 的信道编码后的比特数。
具体地， 根据步骤 402得到的 UE的 ACK/NACK占用的调制符号个数 Q' , 利用公式 （ 2 ) 计算得到 UE的 ACK/NACK的信道编码后的比特数。
Q = Qr Q ( 2 )
其中， β'表示 UE的 ACK/NACK占用的调制符号个数； ρ表示 UE的
ACK/NACK的信道编码后的比特数； 表示调制阶数。
404: UE根据 UE的 ACK/NACK的信道编码后的比特数， 对排序后的
X个下行载波的 ACK/NACK进行信道编码后与数据复用在 PUSCH上传输 给 eNB。
例如：假设在步骤 401中得到的排序后的 X个下行载波的 ACK/NACK 的原始信息为 3bit， 在步骤 403得到 UE的 ACK/NACK信道编码后的比特 数为 20bit， 则该步骤中对排序后的 X个下行载波的 ACK/NACK进行信道 编码时要将 3bit的 ACK/NACK编码为 20bit。并且，本发明实施例中优选采 用 RM ( Reed-Muller )编码， 实际应用中可以根据具体情况采用其他任何 可行的信道编码方式， 对此不做具体限定。
405: eNB根据第一载波集合，计算 ACK/NACK 占用的调制符号个数。 其中， 该步骤中第一载波集合与步骤 402 中第一载波集合相一致， 如 当步骤 402 中第一载波集合为用户下行成员载波集合时， 该步骤中的第一 载波集合也为用户下行成员载波集合。 eNB 根据第一载波集合， 计算 ACK/NACK 占用的调制符号个数的方法与步骤 402相同，此处不再——赘 述。
406: eNB 根据 ACK/NACK 占用的调制符号个数， 提取 UE传输的 ACK/NAC 及计算与 UE传输的 ACK/NACK对应的信道编码后的比特数。
由于 eNB是采用与 UE相一致的方法得到与 UE传输的 ACK/NACK对 应的信道编码后的比特数，因此 eNB得到的与 UE传输的 ACK/NACK对应 的信道编码后的比特数， 与 UE得到的 UE的 ACK/NACK的信道编码后的 比特数也相一致。
407: eNB根据与 UE传输的 ACK/NACK对应的信道编码后的比特数， 对传输的 ACK/NACK进行信道译码， 并根据预设的排序规则， 确定与每个 下行载波对应的 ACK NACK：。
具体地， 可以釆用与步骤 404 中采用的信道编码相对应的译码方法对 传输的 ACK/NACK进行信道译码，或可以釆用任何其他可行的方式进行译 码， 对此不做具体限定。 并且， 该步骤中的预设的排序规则与步骤 401 中 预设的排序规则相一致。 如当步骤 401 中预设的排序规则为按照下行载波 被激活的先后顺序对多个下行载波的 ACK/NACK进行排序时，该步骤中预 设的排序规则也为按照下行载波被激活的先后顺序确定每个下行载波对应 的 ACK/NACK.
需要说明的是， 本实施例中， 在 eNB需要去激活下行载波时， eNB按 照后激活的载波先去激活的顺序， 对下行激活载波集合中包括的下行载波 进行去激活 （如当按照先被激活的下行载波排在前面， 后被激活的下行载 波排在后面的顺序对 X个下行载波的 ACK/NACK进行排序时， eNB从下 行激活载波集合中排在最后的一个下行载波开始进行去激活）。 然后 UE根 据更新了的下行激活载波集合重复步骤 401-404 对 X 个下行载波的 ACK/NAC 进行传输。
并且需要说明的是， 当按照先被激活的下行载波排在前面， 后被激活 的下行载波排在后面的顺序对 X个下行载波的 ACK/NACK进行排序时， 则刚激活的下行载波的 ACK/NACK排在最后，由于在模糊期间刚激活的那 个下行载波通常为 NACK, 则根据 RM编码的特点， 排在后面的 NACK对 总的 ACK/NACK的编码比特不 ^故贡献， 因而此时即使 eNB按照较少或较 多的比特去译码也能保证真正需要传输的那些 ACK/NACK的正确性。举例 来说， 下行激活载波集合中有 3 个下行载波， 其中最后一个下行载波为刚 激活的下行载波， 且每个下行载波支持 ACK/NACK空间捆绑， 则根据 M 编码联合编码的 ACK/NACK总的比特数为 3， £设前两个下行载波都需要 传输 ACK, 最后一个下行载波由于刚激活没有调度数据因而传 NACK, 则 在 PUSCH上传输的 3个比特为 110， 按照 RM编码的特点， 110编码后的 比特与 11编码后的比特一致， 因而 eNB即使还不知道 UE已成功检测下行 载波 3的激活命令并已更新了联合编码的 ACK/NACK的总的比特数从而仍 按 2比特去对传输的 ACK/NACK进行译码也能保证前 2个比特的正确译 码。
本发明实施例所述的传输上行控制信息的方法， UE 通过根据获取的 UE的 ACK/NACK的信道编码后的比特数，对 X个下行载波的 ACK/NACK 进行信道编码后传输给 eNB , 解决了 UE 和 eNB 对多个下行载波的 ACK/NAC 的联合编码的总的原始信息比特数理解不一致，导致 eNB对联 合编码的 ACK/NACK译码错误的问题； 并且 UE通过按照预设的排序规则 对多个下行载波的 ACK/NACK进行排序， 使得 eNB可以确定出与每个下 行载波对应的 ACK/NACK。 UE通过按照下行载波被激活的先后顺序来对 各载波的 ACK/NACK进行排序及 eNB按照后激活的载波先去激活的顺序， 对下行激活载波集合中包括的下行载波进行去激活， 可保证即使存在 eNB 和 UE对联合编码的 ACK/NACK的总的信息比特理解不一致， 也能保证真 正需要传输的 ACK/NACK译码正确，解决了 UE和 eNB对多个下行载波的 ACK/NACK联合编码的总的原始信息比特数理解不一致，导致 eNB对联合 编码的 ACK/NACK译码错误的问题。 利用 RM编码的特点， UE通过按照 先被激活的下行载波排在前面， 后被激活的下行载波排在后面的顺序对 X 个下行载波的 ACK/NACK进行排序及去激活载波时总是从激活载波集合 中的最后一个开始，可保证即使存在 eNB和 UE对联合编码的 ACK/NACK 的总的信息比特理解不一致，也能保证真正需要传输的 ACK/NACK译码正 确，解决了 UE和 eNB对多个下行载波的 ACK/NACK联合编码的总的原始 信息比特数理解不一致，导致基站对联合编码的 ACK/NACK译码错误的问 题。 UE根据第一载波集合计算 UE的 ACK/NACK占用的调制符号个数， 使得 ACK/NACK在 PUSCH上占用的物理资源不随着下行激活载波集合的 变化而变化， 可以保证与 ACK/NACK复用的 PUSCH上的数据正常译码， 降低对数据传输性能的影响， 且相当于分配更多的物理资源给待传输的 ACK/NACK, 提高了 ACK/NACK的传输性能。 为了便于理解本发明实施例，下面以本发明实施例所述的方法应用于 载波聚合场景下， 在一个 PUSCH上传输大于等于 1个下行载波的 CSI为例， 进行进一步地说明。
参见图 5，本发明实施例提供了另一种传输上行控制信息的方法，包括： 501 : UE按照预设的排序规则对 X个下行载波中每个载波的 CSI进行排 序， 其中 X为正整数， 该处 X个下行载波优选地属于 UE的下行激活载波 集合， 该处 X个下行载波可以由 UE的下行激活载波集合、 CSI的高层参数 配置及是否有非周期 CSI上报决定。
其中， 预设的排序规则可以为按照下行载波被激活的先后顺序进行排 序， 并且当有多个下行载波同时被激活时， 可以按照每个下行载波的属性 对同时被激活的多个下行载波的 CSI进行排序， 下行载波的属性可以是载 波索引或载波频率， 具体可以按照下行载波的属性的递增或递减的顺序对 同时被激活的多个下行载波的 CSI进行排序。 或预设的排序规则可以为按 照各 CSI对应的下行载波的属性的递增或递减的顺序进行排序， 下行载波 的属性可以是下行载波的载波索引或载波频率。
具体地， UE可以根据下行激活载波集合， 确定下行载波集合中的 X个 下行载波的 CSI的原始信息。 或优选地 UE还可以根据下行激活载波集合， CSI的高层参数配置， 以及是否有非周期 CSI需要上报，确定每个下行载波 是否需要上报 CSI， 若需要上报则相应的上报模式是什么，从而确定下行载 波集合中的 X个下行载波的 CSI的原始信息及具体为哪几个下行载波， 例 如： 假设更新了的下行激活载波集合中包括 CC1、 CC2及 CC3三个下行载 波（设 CC3为刚激活的下行载波）， 根据 CSI的高层参数配置， 此时有 CC1 和 CC3需要上报 CSI，且根据它们各自的高层参数配置， CC 1需上报 0 比 特， CC3需上报 < 3 Cffl比特， 则下行载波集合中的 X个下行载波的 CSI的原 始信息比特数 Ocs = 0 + C 并且下行载波具体为 CC 1和 CC3。
502: UE根据第一载波集合， 计算 UE的 CSI占用的调制符号个数。 其中， 第一载波集合可以为用户下行成员载波集合，或可以为 UE可支 持的最大下行载波集合，或可以为用户下行成员载波集合和 UE可支持的最 大下行载波集合二者中的较小者。 具体地， UE可以根据第一载波集合， 计 算得到 UE的 CSI占用的调制符号个数。或优选地 UE可以根据第一载波集 合， CSI的高层参数配置， 以及是否有非周期 CSI需要上报， 利用公式（3 ) 计算得到 UE的 CSI占用的调制符号个数。
Figure imgf000019_0001
其中， 表示 UE的 CSI占用的调制符号个数； 0表示第一载波集合对 应的所有 CSI的总的信息比特数， 其基于 CSI的高层参数配置、 是否有非 周期 CSI上报、 高层为需要上报 CSI的下行载波配置的 CSI的上报模式来 计算； N^表示 CSI映射到的码字对应的总层数； M^cfai表示同一个传 输块初传时所占的 PUSCH 的传输带宽； 表示当前子帧对应的 PUSCH的传输带宽； Ns CH-ini'ial表示同一个传输块初传时所占的 SC-FDMA 符号的个数； N ™表示当前子帧所占的 SC-FDMA符号的个数； 表示 CRC 校验位的比特数， 对 CQI进行 RM编码时 £取值为 0， 对 CQI进行卷积编 码时 取值为 8; 表示 CSI相对于数据 MCS的偏移， Γ = ，/^ 的取值由高层 RRC信令通知； C表示码块的个数； 表示第 个码块的信 息比特数与 CRC校验比特数之和。
503: UE根据 UE的 CSI占用的调制符号个数，计算 UE的 CSI的信道 编码后的比特数。
具体地， 根据步骤 502得到的 UE的 CSI占用的调制符号个数 ρ'， 利 用公式 （4 )计算得到 UE的 CSI的信道编码后的比特数。
Q = Qm Q' ( 4 ) 其中， β'表示 UE的 CSI占用的调制符号个数； ρ表示 UE的 CSI的信 道编码后的比特数； ^表示调制阶数。
504: UE根据 UE的 CSI的信道编码后的比特数， 对排序后的 X个下 行载波的 CSI进行信道编码后与数据复用在 PUSCH上传输给 eNB。
具体地， 本发明实施例中优选地， 当 X个下行载波的 CSI的原始信息 比特数 >Cffl小于等于 11比特时釆用 RM编码， 大于 11比特时采用卷积码。 可以根据实际应用状况设置其他任何可行的编码方法， 对此不做具体限定。
505: eNB根据第一载波集合， 计算 CSI 占用的调制符号个数。
其中， 该步骤中第一载波集合与步骤 502 中第一载波集合相一致， 如 当步骤 502 中第一载波集合为用户下行成员载波集合时， 该步骤中的第一 载波集合也为用户下行成员载波集合。 eNB根据第一载波集合，计算 CSI 占 用的调制符号个数的方法与步骤 502相同， 此处不再——赘述。
506: eNB根据 CSI 占用的调制符号个数，提取 UE传输的 CSI及计算 与 UE传输的 CSI对应的信道编码后的比特数。
由于 eNB是采用与 UE相一致的方法得到与 UE传输的 CSI对应的信 道编码后的比特数， 因此 eNB得到的与 UE传输的 CSI对应的信道编码后 的比特数， 与 UE得到的 UE的 CSI的信道编码后的比特数也相一致。
507: eNB根据与 UE传输的 CSI对应的信道编码后的比特数， 对传输 的 CSI进行信道译码， 并根据预设的排序规则， 确定与每个下行载波对应 的 CSI。
具体地，信道译码方法可以为盲检测， 所述盲检测的方法是指： 当 eNB 收到传输的 CSI信息后， 可根据载波激活 /去激活前后激活载波集合可能出 现的变化对 CSI进行盲译码， 即根据载波激活 /去激活前后激活载波集合可 能出现的变化确定多个激活载波集合， 分别根据所述确定的每个激活载波 集合按照步骤 501 中的方法计算联合编码的原始信息比特数， 然后结合计 算的联合信道编码后的 CSI的比特数进行信道译码， 并将 CRC校验正确或 似然函数最大的那次译码确定为译码输出。 或可以采用任何其他可行的方 式进行译码， 对此不做具体限定。
并且， 该步骤中的预设的排序规则与步骤 501 中预设的排序规则相一 致。 如当步骤 501 中预设的排序规则为按照下行载波被激活的先后顺序对 多个下行载波的 CSI进行排序的顺序时， 该步骤中预设的排序规则也为按 照下行载波被激活的先后顺序确定每个下行载波对应的 CSI，并按该顺序确 定与每个下行载波对应的 CSI。
本发明实施例所述的传输上行控制信息的方法， UE 通过根据获取的 UE的 CSI的信道编码后的比特数， 对 X个下行载波的 CSI进行信道编码 后传输给 eNB， 解决了 UE和 eNB对多个下行载波的 CSI的联合编码的总 的原始信息比特数理解不一致导致 eNB对联合编码的 CSI译码错误的问题； 并且 UE通过按照预设的排序规则对多个下行载波的 CSI进行排序， 使得 eNB可以确定出与每个下行载波对应的 CSI。 eNB通过盲检测可以进一步 地解决 UE和 eNB对多个下行载波的 CSI联合编码的总的原始信息比特数 理解不一致， 导致 eNB对联合编码的 CSI译码错误的问题。 UE根据第一 载波集合计算 UE的 CSI占用的调制符号个数，使得 CSI在 PUSCH上占用 的物理资源不随着下行激活载波集合的变化而变化， 可以保证与 CSI复用 的 PUSCH上的数据正常译码， 降低对数据传输性能的影响， 且相当于分配 更多的物理资源给待传输的 CSI， 提高了 CSI的传输性能。 需要说明的是， 在图 4所示的实施例或图 5所示的实施例的基 通过 对步骤 401或 501， 及步骤 402或 502进行修改， 可用于解决通过 RRC信 令重配用户下行成员载波集合带来的 UE和 eNB对多个下行载波的 UCI的 原始联合信道编码信息比特数理解不一致， 导致 eNB对联合信道编码后的 UCI译码错误的问题， 修改后的步骤 401或 501具体如下：
当 UE检测到 DL CC set的重配置 RRC信令后， UE对下行激活载波集 合进行更新， UE按照预设的排序规则对 X个下行载波中每个下行载波的 UCI进行排序， 其中， X为正整数， X个下行载波属于 UE的更新后的下行 激活载波集合， 且此处 X个下行载波为 UE的更新后的下行载波集合中的 所有下行载波的个数。
修改后的步骤 402或 502具体如下：
UE根据第一载波集合， 计算 UE的 UCI占用的调制符号个数， 其中， 该处第一载波集合为 UE可支持的最大下行载波集合，或 UE可支持的最大 下行载波集合与 eNB当前可支持的最大下行载波集合二者中的较小者。
其他过程与实施例 5或 6类似， 此处不再——赘述。
本发明实施例所述的传输上行控制信息的方法， UE 通过根据获取的 UE的 UCI的信道编码后的比特数， 对 X个下行载波的 UCI进行信道编码 后传输给 eNB， 解决了 UE和 eNB对多个下行载波的 UCI的联合编码的总 的原始信息比特数理解不一致导致 eNB对联合编码的 UCI译码错误的问 题； 并且 UE通过按照预设的排序规则对多个下行载波的 UCI进行排序， 使得 eNB可以确定出与每个下行载波对应的 UCI。 eNB通过 UCI的特定的 排序顺序或盲检测可以进一步地解决 UE和 eNB对多个下行载波的 UCI联 合编码的总的原始信息比特数理解不一致， 导致 eNB对联合编码的 UCI译 码错误的问题。 UE根据第一载波集合计算 UE的 UCI占用的调制符号个数， 使得 UCI在 PUSCH上占用的物理资源不随着下行激活载波集合的变化而 变化， 可以保证与 UCI复用的 PUSCH上的数据正常译码， 降低对数据传 输性能的影响，且相当于分配更多的物理资源给待传输的 UCI，提高了 UCI 的传输性能。 通过在 UE检测到 DL CC set的重配置 RRC信令后， UE对下 行激活载波集合进行更新， 基于更新后的下行激活载波集合进行与图 4或 图 5所示的实施例类似的传输，第一载波集合釆用 UE可支持的最大下行载 波集合， 或 UE可支持的最大下行载波集合与 eNB当前可支持的最大下行 载波集合二者中的较小者解决了通过 RRC信令重配用户下行成员载波集合 带来的 UE和 eNB对多个下行载波的 UCI的原始联合信道编码信息比特数 理解不一致， 导致 eNB对联合信道编码后的 UCI译码错误的问题。 为了便于理解本发明实施例，下面以本发明实施例所述的方法应用于载 波聚合场景下， 采用复用 （Multiplexing )方式在一个 PUCCH上传输大于等 于 1个下行载波的 ACK/NACK为例， 进行进一步地说明。
参见图 6，本发明实施例提供了另一种传输上行控制信息的方法，包括： 601： UE 按照预设的排序规则对 X 个下行载波中每个载波的 ACK/NAC 进行排序， 其中， X为正整数， X个下行载波属于 UE的下行 激活载波集合， 且此处 X个下行载波为 UE的下行载波集合中的所有下行 载波。
其中， 预设的排序规则可以为按照下行载波被激活的先后顺序进行排 序， 并且当有多个下行载波同时被激活时， 可以按照每个下行载波的 ACK/NAC 对应的下行载波的属性对同时被激活的多个下行载波的 ACK/NACK进行排序， 下行载波的属性可以是下行载波的载波索引或载波 频率， 具体可以按照下行载波的属性的递增或递减的顺序对同时被激活的 多个下行载波的 ACK/NACK进行排序。
具体地，对 X个下行载波中的每个下行载波：若需要反馈 ACK/NACK, 且 ACK/NACK支持空间捆绑，则每个下行载波对应 1比特 ACK或 NACK; 若需要反馈 ACK7NACK, 且 ACK/NACK不支持空间捆绑， 则每个下行载 波对应 2比特 ACK或 NACK。 若不需要反馈 ACK/NACK, 且 ACK/NACK 支持空间捆绑， 则每个下行载波对应 1 比特 NACK ; 若不需要反馈 ACK/NACK, 且 ACK/NACK不支持空间捆绑， 则每个下行载波对应 2比 特 NACK。 所谓需要反馈 ACK/NACK 是指在该载波上检测到需要反馈 ACK/NAC 的信息， 如数据或指示释放下行 SPS资源的 PDCCH信令。
UE根据上述方法确定 X个下行载波中的每个下行载波的 ACK/NACK 的原始信息，使得 X个下行载波中的总的原始信息比特数 为： oACK = X 或 a4 = 2X。 X 对应 ACK/NACK 支持空间捆绑时的场景， 2X 对应 ACK/NAC 不支持空间捆绑时的场景。
602: UE根据预设的 UE的 ACK/NACK的信道编码后的比特数， 对排 序后的 X个下行载波的 ACK/NACK进行信道编码后映射到 PUCCH信道上 传输给 eNB。
其中， 预设的 UE的 ACK/NACK的信道编码后的比特数为正整数， 例 如可以为 20。 且本发明实施例中优选釆用 RM编码方式进行信道编码， 实 际应用中可以根据具体情况釆用其他任何可行的信道编码方式， 对此不做 具体限定。
603 : eNB通过解 PUCCH对传输的 ACK NACK进行检测， 并根据预 设的排序规则， 确定与每个下行载波对应的 AC /NACK。
其中， 该步骤中的预设的排序规则与步骤 601 中预设的排序规则相一 致。 并且具体地， eNB对传输的 ACK/NACK进行检测中的信道译码的方法 可以为：
采用与步骤 602 中编码相应的方法根据预设的信道编码后的比特数对 传输的 ACK/NACK进行信道译码； 或
釆用盲译码的方式进行译码。 所述盲译码的方法是指： 当 eNB收到传 输的 ACK/NACK信息后， 可根据载波激活 /去激活前后下行激活载波集合 可能出现的变化对 ACK/NACK进行盲译码， 即根据载波激活 /去激活前后 下行激活载波集合可能出现的变化确定多个下行激活载波集合， 分别才艮据 所确定的每个下行激活载波集合并结合预设的信道编码后的比特数进行信 道译码， 并将似然函数最大的那次译码确定为译码输出。
需要说明的是， 当 eNB不是釆用盲译码对传输的 ACK/NACK进行译 码时， 在 eNB需要去激活下行载波时， eNB按照后激活的载波先去激活的 顺序，对下行激活载波集合中包括的载波进行去激活。 然后 UE根据更新了 的下行激活载波集合重复步骤 601-602对 X个下行载波的 ACK/NACK进行 传输。
并且需要说明的是， 当按照先被激活的下行载波排在前面， 后被激活 的下行载波排在后面的顺序对 X个下行载波的 ACK/NACK进行排序时， 则刚激活的下行载波的 ACK/NACK排在最后，由于在模糊期间刚激活的那 个下行载波通常为 NACK, 则根据 RM编码的特点， 排在后面的 NACK对 总的 ACK/NACK的编码比特不^贡献， 因而此时即使 eNB按照较少或较 多的比特去译码也能保证真正需要传输的那些 ACK/NACK的正确性。举例 来说， 下行激活载波集合中有 3 个下行载波， 其中最后一个下行载波为刚 激活的下行载波， 且每个下行载波支持 ACK/NACK空间捆绑， 则根据 M 编码联合编码的 ACK NACK总的比特数为 3， ^^设前两个下行载波都需要 传输 ACK， 最后一个下行载波由于刚激活没有调度数据因而传 NACK, 则 在 PUSCH上传输的 3个比特为 110， 按照 RM编码的特点， 110编码后的 比特与 11编码后的比特一致， 因而 NB即使还不知道 UE已成功检测下行 载波 3的激活命令并已更新了联合编码的 ACK/NACK的总的比特数从而仍 按 2比特去对传输的 ACK/NACK进行译码也能保证前 2个比特的正确译 码。
本发明实施例所述的传输上行控制信息的方法， UE 通过根据预设的 UE的 ACK/NACK的信道编码后的比特数，对 X个下行载波的 ACK/NACK 进行信道编码后传输给 eNB , 解决了 UE 和 eNB 对多个下行载波的 ACK/NAC 的联合编码的总的原始信息比特数理解不一致导致 eNB对联 合编码的 ACK/NACK译码错误的问题； 并且 UE通过按照预设的排序规则 对多个下行载波的 ACK/NACK进行排序， 使得 eNB可以确定出与每个下 行载波对应的 ACK/NACK。 进一步地， eNB不采用盲译码时， UE利用 RM 编码的特点， 通过按照下行载波被激活的先后顺序来对各载波的 ACK/NAC 进行排序及 eNB按照后激活的载波先去激活的顺序，对下行激 活载波集合中包括的下行载波进行去激活， 可保证即使存在 eNB和 UE对 联合编码的 ACK/NACK的总的信息比特理解不一致，也能保证真正需要传 输的 ACK/NACK 译码正确， 解决了 UE 和 eNB 对多个下行载波的 ACK/NACK联合编码的总的原始信息比特数理解不一致，导致 eNB对联合 编码的 ACK/NACK译码错误的问题； 若 eNB采用盲检测， 则无需限定去 激活载波的顺序， 即可以进一步地解决 UE 和 eNB 对多个下行载波的 ACK/NACK联合编码的总的原始信息比特数理解不一致，导致 eNB对联合 编码的 ACK/NACK译码错误的问题。 当 UE有上行数据需要发送但又没有上行资源时， UE会向 eNB发送 SR ( Schedul ing Reques t , 调度请求）请求分配资源。 载波聚合场景下， 将 半静态配置一个 UE特定的上行载波来发送 SR， 以及 ACK/NACK。 当 SR与 X 个下行载波的 ACK/NACK同时在一个上行子帧上报时， 可以将 SR与 X个下 行载波的 ACK/MCK进行联合信道编码后传输。 基于上述场景， 参见图 7， 本发明实施例提供了另一种传输上行控制信息的方法， 该方法包括：
701 : UE按照预设的排序规则对 SR和 X个下行载波的 ACK/NACK 进行排序， 其中， X为正整数， X个下行载波属于 UE的下行激活载波集合， 且此处 X个下行载波为 UE的下行载波集合中的所有下行载波的个数。
其中， 本发明实施例中预设的排序规则为： 按照先排列 SR， 再按照下 行载波被激活的先后顺序将 X 个下行载波中每个下行载波的 ACK/NACK 依次排列在 SR的后面的顺序进行排序。并且当有多个下行载波同时被激活 时，可以按照每个下行载波的 ACK/NACK对应的下行载波的属性对同时被 激活的多个下行载波的 ACK/NACK进行排序，下行载波的属性可以是下行 载波的载波索引或载波频率， 具体可以按照下行载波的属性的递增或递减 的顺序对同时被激活的多个下行载波的 ACK/NACK进行排序。
具体地，对 X个下行载波中的每个下行载波：若需要反馈 ACK/NACK, 且 ACK/NACK支持空间捆绑，则每个下行载波对应 1比特 ACK或 NACK; 若需要反馈 ACK/NACK, 且 ACK/NACK不支持空间捆绑， 则每个下行载 波对应 2比特 ACK或 NACK。 若不需要反馈 ACK/NACK, 且 ACK/NACK 支持空间捆绑， 则每个下行载波对应 1 比特 NACK; 若不需要反馈 ACK/NACK, 且 ACK/NACK不支持空间梱绑， 则每个下行载波对应 2比 特 NACK。 所谓需要反馈 ACK/NACK 指在该载波上检测到需要反馈 ACK/NAC 的信息， 如数据或指示释放下行 SPS资源的 PDCCH信令。
UE根据上述方法确定 X个下行载波中的每个下行载波的 ACK/NACK 的原始信息，使得 X个下行载波中的总的原始信息比特数 为： oACK = X : 2X。 X 对应 ACK/NACK 支持空间捆绑时的场景， 2X 对应 ACK/NACK不支持空间捆绑时的场景。并根据 X个下行载波中的总的原始 信息比特数及 SR的原始信息， 得到联合编码的总的原始信息比特数。
702: UE根据预设的 UE的 ACK/NACK的信道编码后的比特数， 对排 序后的 SR和 X个下行载波的 ACK/NACK进行信道编码后映射到 PUCCH 信道上传输给 e肌 与步骤 602类似， 此处不再——赘述。
703： eNB通过解 PUCCH对传输的 SR和 ACK/NACK进行检测， 确定 SR 及与每个下行载波对应的 ACK/NACK：。
与步骤 603类似， 此处不再——赘述。
本发明实施例所述的传输上行控制信息的方法， 不但解决了与图 6所 示的实施例类似的问题， 同时还保证了 SR的正确传输。
参见图 8，本发明实施例提供了另一种传输上行控制信息的方法， 包括：
801 : UE接收到载波激活 /去激活信令， 判断是激活载波和 /或去激活载 波， 对于激活的载波则将新激活的载波加入原下行激活载波集合并执行 802; 对于去激活的载波， 执行 807。
802： UE按照预设的排序规则对 X个下行载波中每个载波的 ACK/NACK 进行排序。
与步骤 401类似， 此处不再——赘述。
803: UE根据第一载波集合， 计算 UE的 ACK/NACK占用的调制符号个 数。 UE根据 UE的 ACK/NACK占用的调制符号个数， 计算 UE的 ACK/NACK 的信道编码后的比特数。
与步骤 402和步骤 403类似， 此处不再——赘述。
804: UE根据 UE的 ACK/NACK的信道编码后的比特数， 对排序后的 X 个下行载波的 ACK/NACK进行信道编码后与数据复用在 PUSCH上传输给 e肌
与步骤 404类似， 此处不再——赘述。
805: eNB根据第一载波集合，计算 ACK/NACK 占用的调制符号个数。 eNB根据 ACK/NACK 占用的调制符号个数， 提取 UE传输的 ACK/NACK及 计算与 UE传输的 ACK/NACK对应的信道编码后的比特数。
与步骤 405和步骤 406类似， 此处不再——赘述。
806: eNB根据与 UE传输的 ACK/NACK对应的信道编码后的比特数，对 传输的 ACK/NACK进行信道译码， 并根据预设的排序规则， 确定与每个下 行载波对应的 ACK/NACK。
与步骤 407类似， 此处不再——赘述。
807: UE判断是否至少有一个载波隐式去激活定时器的定时时间到达， 如果至少有一个载波隐式去激活定时器的定时时间到达，则执行 808;否则， 执行 802。
808: UE将下行激活载波集合更新为去激活后的下行激活载波集合， 然 后执行 802。
本发明实施例所述的传输上行控制信息的方法， 对于载波激活的情况： 利用 RM 编码的特点， UE 通过按照载波激活的先后顺序来对各载波的 ACK/NACK进行排序及去激活载波时总是从激活载波集合中的最后一个开 始， 可保证即使存在基站和 UE对联合编码的 ACK/NACK的总的信息比特 理解不一致， 也能保证真正需要传输的 ACK/NACK译码正确， 解决了 UE 和 eNB对多个下行载波的 ACK/NACK联合编码的总的原始信息比特数理 解不一致， 导致基站对联合编码的 ACK/NACK译码错误的问题； 同时， UE根据第一载波集合计算 X个下行载波的 ACK/NACK占用的调制符号个 数， 使得 ACK/NACK在 PUSCH上占用的物理资源不随着下行激活载波集 合的变化而变化， 可以保证与 ACK/NACK复用的 PUSCH上的数据正常译 码， 降低对数据传输性能的影响， 且相当于分配更多的物理资源给待传输 的 ACK/NACK, 提高了 ACK/NACK的传输性能。 对于载波去激活的情况： 通过结合载波去激活的隐式机制， 解决了 UE 和 eNB 对多个下行载波的 ACK/NAC 联合编码的总的原始信息比特数理解不一致导致基站对联合编 码的 ACK/NACK译码错误的问题
参见图 9，本发明实施例提供了另一种传输上行控制信息的方法， 包括：
901 : UE在下行子帧 n接收载波激活 /去激活信令， UE将接收载波激 活 /去激活信令之前的下行激活载波集合作为当前下行激活载波集合， UE 按照预设的排序规则对 X个下行载波中每个下行载波的 UCI进行排序， 其 中， X为正整数， X个下行载波属于 UE的当前下行激活载波集合。
具体地： 当所述 UCI为 ACK/NACK时， X个下行载波为 UE的下行载 波集合中的所有下行载波； 当 UCI为 CSI时， X个下行载波可以由 UE的 下行激活载波集合、 CSI的高层参数配置及是否有非周期 CSI上报决定。 序的过程， 当所述 UCI为 ACK/NACK时与步骤 401类似， 当所述 UCI为 CSI 时与步骤 501类似， 此处不再——赘述。
902: UE 向 eNB传输 X个下行载波的 UCI, eNB对接收到的 X个下 行载波的 UCI进行处理。 具体地： 当所述 UCI 为 ACK/NACK 时， 可以采用步骤 402-407 或 602-603的方法实现； 当所述 UCI为 CSI时， 可以采用步骤 502-507的方法 实现。
需要说明的是： 该步骤 UE在采用类似步骤 402或 502计算 UE的 UCI 占用的调制符号个数时， 所述第一载波集合还可为在下行子帧 n发送载波 激活 /去激活信令前的下行激活载波集合； 该步骤 eNB在采用类似步骤 405 或 505计算 UCI 占用的调制符号个数时，所述第一载波集合还可为 eNB在 下行子帧 n发送载波激活 /去激活信令前的下行激活载波集合。
903 : UE从第一个有效的上行子帧 n+k起， 将更新后的下行激活载波 集合（即其在下行子帧 n接收到的载波激活 /去激活信令后更新的下行激活 载波集合 )作为当前下行激活载波集合， UE按照预设的排序规则对 X个下 行载波中每个下行载波的 UCI进行排序， 其中， X为正整数， X个下行载 波属于 UE的当前下行激活载波集合。 其中， k表示子帧延迟数， k为正整 数。
其中， 第一个有效的上行子帧 n+k是指从 UE接收载波激活 /去激活信令 所在子帧 n向后推迟 k个子帧后， UE遇到的第一个需要上报 UCI的上行子帧。 可以根据实际情况来选取 k的具体取值， 例如 k大于等于 5。
具体地： 当所述 UCI为 ACK/NACK时， X个下行载波为 UE的下行载 波集合中的所有下行载波； 当 UCI为 CSI时， X个下行载波可以由 UE的 下行激活载波集合、 CSI的高层参数配置及是否有非周期 CSI上报决定。

需要说明的是， 该步骤中 UE从第一个有效的上行子帧 n+k起， 将更 新后的下行激活载波集合（即其在下行子帧 n接收到载波激活 /去激活信令 后更新的下行激活载波集合）作为当前下行激活载波集合， 直至需根据新 的载波激活 /去激活信令重新更新。
904: UE 向 eNB传输 X个下行载波的 UCI， eNB对接收到的 X个下 行载波的 UCI进行处理。
具体地： 当所述 UCI 为 ACK/NACK 时， 可以采用步骤 401-407 或 601-603的方法实现； 当所述 UCI为 CSI时， 可以采用步骤 501-507的方法 实现。
