  • the uplink carrier is called an uplink primary carrier, and the sequence related information of the PUCCH is determined by a cell identifier corresponding to the uplink carrier.
  • the data carried by the PUCCH format lb (PUCCH format lb) channel is composed of a cyclic shift of a Zad-off Chu (ZC) sequence in the frequency domain, and is multiplied by a spreading code by ACK or NACK in the time domain.
  • PUCCH format lb channels in one resource block (RB, resource block) are The cyclic shift of the ZC sequence and the time domain spreading code are distinguished, that is, one PUCCH format lb channel includes a cyclic shift of a ZC sequence and a time domain spreading code, and the ZC sequence is sent by the uplink of the PUCCH.
  • the cell identity corresponding to the carrier is determined.
  • Channel selection means that the same PUCCH information (such as modulation symbols) is transmitted on different PUCCH channels to indicate different information. For example, the same modulation symbol is transmitted on PUCCH format lb channel 1 to indicate ACK, and PUCCH format lb channel 2 is transmitted to indicate NACK. .
  • the allocation of the channel resources of the PUCCH format lb specifically includes: the channel resources of the PUCCH format lb are implicitly determined by the parameters of the corresponding PDCCH, for example, the PUCCH format lb resource is determined by the CCE index of the PDCCH.

  • RRC radio resource control
  • PUCCH format 3 has no cyclic shift of ZC sequence in the frequency domain, and only has a spreading code in the time domain, and channel resources of different PUCCH format 3 in one resource block are distinguished by the above spreading code.
  • a channel of PUCCH format 3 on different orthogonal frequency division multiplexing (OFDM) symbols of one subframe may adopt different cyclic shifts of modulation symbols spread by the time domain spreading code Bit code. Which cyclic shift code is used is determined based on the cell identifier corresponding to the uplink carrier of the PUCCH.

  • the bits dynamically indicate to the UE one of the four resources for current use.
  • carrier aggregation between base stations with non-ideal backhaul is introduced, that is, data cannot be transmitted in real time between base stations, and as a result, scheduling between multiple carriers belonging to different base stations is performed independently. That is to say, when one base station schedules one carrier in the aggregated carrier, it is not clear on the other carrier scheduled by another base station.

Description

上行控制信息的发送方法和装置
技术领域
本发明实施例涉及无线通信领域, 尤其涉及上行控制信息的发送方法和装 置。 背景技术
在早期的长期演进( LTE, long term evolution )***中, 用户设备 (UE, user equipment)的上行和下行都只能被一个载波服务。 随着标准的进展, 引入了载波 聚合 (CA, carrier aggregation)技术,此时一个 UE可以同时被多个上行载波服务, 也可以同时被多个下行载波服务, 以提高 UE的峰值数据速率。早期的载波聚合 ***都是同一个基站下的载波进行聚合, 或者是有理想回传 (backhaul)的宏小区 和微小区下的载波聚合。 其中, 有理想回传的两个节点可以看做是同一个基站。 其中, 理想回传指该回传的传输时延很小可以忽略, 比如, 宏基站和微基站通 过光纤连接构成的回传, 这些光纤连接的多个节点之间的延时很小。 这种情况 下, 由于基站在调度聚合载波中的一个载波时, 也能够实时地知道另一个载波 上的调度情况, 因此, 这些载波间可以采用联合调度。 现有 CA***中, 下行数 据调度对应的确认 (ACK, acknowledge)或非确认 (NACK, non-acknowledge)承载 在物理上行控制信道 (PUCCH, physical uplink control channel)上, 该 PUCCH只 在一个上行载波上发送, 这个上行载波称为上行主载波, 该 PUCCH的序列相关 信息是通过该上行载波对应的小区标识确定的。
现有 CA***中, PUCCH的反馈模式有两种, 一种是 PUCCH格式 lb结 合信道选择的反馈模式, 另一种是 PUCCH格式 3的反馈模式。
对于 PUCCH格式 lb结合信道选择的反馈模式:
PUCCH格式 lb ( PUCCH format lb )信道承载的数据在频域上是由一个 Zad-off Chu(ZC)序列的循环移位构成,在时域上是由 ACK或 NACK乘以一个扩 频码构成。 一个资源块 (RB, resource block)中的不同 PUCCH格式 lb信道是通 过上述 ZC序列的循环移位和时域扩频码来区分的, 即一个 PUCCH格式 lb信 道包括一个 ZC序列的循环移位和一个时域扩频码, 所述 ZC 序列由发送该 PUCCH的上行载波对应的小区标识确定。信道选择是指同样的 PUCCH信息(如 调制符号)在不同的 PUCCH信道发送表示不同的信息, 比如同样的调制符号在 PUCCH格式 lb信道 1上发送表示 ACK,在 PUCCH格式 lb信道 2上发送表示 NACK。
对于主载波的下行调度, PUCCH格式 lb的信道资源的分配方式具体包括: PUCCH格式 lb的信道资源通过对应的 PDCCH的参数进行隐式确定,比如通过 PDCCH的 CCE索引(index)确定 PUCCH格式 lb资源,或通过 ePDCCH的 eCCE 索引和 /或天线端口号等确定 PUCCH格式 lb 资源; 为了便于描述, 下文中的 PDCCH和 ePDCCH都以 PDCCH来表示; 对于辅载波的下行调度, PUCCH格 式 lb资源分配的方式采用高层预留结合 PDCCH动态选择的方案, 具体包括: PUCCH格式 lb的信道资源可以通过无线资源控制( RRC, radio resource control ) 信令配置 4组信道资源,然后基站通过调度辅载波的 PDCCH中的两个比特来动 态地向 UE指示者 4组信道资源中的一组来供当前使用。
对于 PUCCH格式 3的反馈模式:
PUCCH格式 3在频域上没有 ZC序列的循环移位, 只在时域上有一个扩频 码,一个资源块中的不同 PUCCH格式 3的信道资源是通过上述扩频码来区分的。 在一个子帧的不同的正交频分复用(OFDM , orthogonal frequency division multiplexing)符号上的 PUCCH格式 3的信道, 可以采用经过该时域扩频码扩频 后的调制符号的不同的循环移位码。采用哪个循环移位码是根据该 PUCCH的上 行载波对应的小区标识确定的。
PUCCH格式 3信道资源的分配的方式采用高层预留结合 PDCCH动态选择 的方案, 具体包括: PUCCH格式 3的信道资源可以通过 RRC信令配置 4个资 源, 然后基站通过调度辅载波的 PDCCH中的两个比特来动态地向 UE指示在这 4个资源中一个来供当前使用。 在后续演进的 LTE***中, 会引入具有非理想回传的基站间的载波聚合, 即基站间无法实时传送数据, 这样导致的结果是隶属于不同基站的多个载波间 的调度是独立进行的, 也就是说, 一个基站调度聚合载波中的一个载波时, 并 不清楚另一个基站调度的另一个载波上的情况。
例如: 部署在频率 fl的宏小区主要提供***信息和进行无线链路监测和移 动性管理, 以保证业务的连续性; 部署在频率 f2多个微小区主要提供高数据速 率业务的传输, 并且, 所述多个微小区在宏小区的覆盖范围内。 上述宏小区和 微小区, 还有微小区之间都是非理想回传, 即无法实时交互信息。
在上述具有非理想回传的基站间的 CA ***中, 由于多个下行载波的数据 调度是每个基站独立进行的, 比如在频率 fl的宏基站和在频率 f2的微基站独立 调度, 一个直接的方案就是把多个 PUCCH分别在多个载波上发送,从而分别把 ACK或 NACK反馈给各自的基站。 然而, 有些低端 UE的上行没有多个载波的 发射能力; 即使某些高端 UE的上行具有多个载波的发射能力, 在 UE功率受限 时, 同时发射多个 PUCCH会影响 PUCCH的性能。 发明内容
有鉴于此, 本发明实施例提供了上行控制信息的发送方法和装置, 以解决 在 CA***中, 如何发送 PUCCH的问题。

上述现有技术的 PUCCH的发送模式, 在基站间的载波聚合***下是不适 用的。 由于基站间的下行调度是独立的, 各基站无法实时获知其他基站的信道 资源的调度情况, 因此上述 PUCCH信道资源分配的方案是无法应用的。 例如, 对于高层预留结合 PDCCH动态选择的方案, 假设宏基站的 fl为主载波, 宏基 站并不能实时获知微基站调度的 PDCCH中的动态指示的两个比特的具体状态, 也就无法获取该显式指示的 PUCCH格式 3或 PUCCH格式 lb的信道资源。
因此, 需要多个基站同时接收的 PUCCH信道资源必须是半静态预留或静 态预留的, 比如, 可以通过 RRC信令配置 PUCCH信道资源, 而不可以进一步 动态地从 RRC信令通知的多组或多个资源中选择其中一个使用。 但纯半静态预 留的 PUCCH信道资源会造成资源开销较大,尤其是在宏基站覆盖范围内做宏基 站和微基站间 CA的 UE数较多的情况下, 信道资源开销大的问题尤为严重。 因 此本发明实施例采用信道资源的复用机制,即同一个 PUCCH信道资源或同一组 PUCCH信道资源可供多个 UE同时使用,又尽量降低复用资源带来的干扰问题。
基于上述问题, 本发明一实施例提供了一种上行控制信息的发送方法, 如 图 1所示。 本实施例的方法包括如下步骤。
步骤 110, UE接收网络设备通过下行控制信道调度的下行数据, 其中, 所 述下行控制信道为服务小区对应的下行控制信道,所述服务小区是为所述 UE配 置的至少两个服务小区中的服务小区, 所述至少两个服务小区包括一个主服务 小区和至少一个辅月良务小区。
步骤 120, 根据所述下行控制信道选择标识信息。
步骤 130, 利用所述选择的标识信息生成所述下行数据对应的物理上行控 制信道。
步骤 140, 在所述物理上行控制信道的信道资源上发送所述物理上行控制 信道。
通过采用本实施例的方法, 由于 UE发送的物理上行控制信道是使用相应 的标识信息生成的, 这样, 在收到上述物理上行控制信道之后, 向 UE发送了下 行控制信道的网络设备能够根据使用的标识信息区分出对应的物理上行控制信 道, 实现了多个网络设备间复用相同的 PUCCH信道资源, 而不需要实时获知其 他基站的下行数据的调度情况, 达到了小区***的增益,提高了 PUCCH信道资 源的利用率。
本发明另一实施例提供了一种上行控制信道的接收方法, 如图 2所示。 本 实施例的方法包括如下步骤。
步骤 210, 网络设备向用户设备 UE发送下行控制信道调度的下行数据, 其 中, 所述下行控制信道为所述网络设备对应的辅服务小区对应的下行控制信道, 所述辅服务小区是为所述 UE配置的至少两个服务小区中的服务小区,所述至少 两个服务小区还包括一个主服务小区。
步骤 220 , 确定所述 UE可能使用的标识信息。
步骤 230, 在用于反馈所述物理上行控制信道的信道资源上, 使用所述可 能使用的标识信息检测所述下行数据对应的所述物理上行控制信道, 其中, 所 述物理上行控制信道是所述 UE使用所述 UE可能使用的标识信息中的一种生成 的。
通过采用本实施例的方法, 由于 UE发送的物理上行控制信道是使用相应 的标识信息生成的, 这样, 在收到上述物理上行控制信道之后, 向 UE发送了下 行控制信道的主服务小区对应的网络设备能够根据该标识信息区分出对应的物 理上行控制信道, 实现了多个网络设备间复用相同的 PUCCH信道资源, 而不需 要实时获知其他基站的 PUCCH信道资源的调度情况, 达到了小区***的增益, 提高了 PUCCH信道资源的利用率。
本发明另一实施例还提供了一种上行控制信息的传输方法, 如图 3所示。 本实施例的方法包括如下步骤。
步骤 310, UE接收网络设备通过下行控制信道调度的下行数据, 其中, 所 述下行控制信道为服务小区对应的下行控制信道,所述服务小区是为所述 UE配 置的至少两个服务小区中的服务小区, 所述至少两个服务小区包括一个主服务 小区和至少一个辅服务小区。
需要说明的是, 本发明实施例中, 下行控制信道包括 PDCCH 和 /或 ePDCCH, 本文均以 PDCCH为例进行描述, ePDCCH的实现方式与 PDCCH相 同。
其中, 一个下行控制信道可以对应一个服务小区。
UE在被配置了至少两个服务小区后,即可获取网络设备所配置的所述至少 两个服务小区的配置信息。
其中, UE可以通过 RRC信令获取网络设备配置的至少两个服务小区的配 置信息。 例如, UE初始从主服务小区接入, 然后网络设备发现该 UE的数据需 求增加, 就进一步通过 RRC信令为该 UE添加了一个辅服务小区。 这里只是一 种配置两个服务小区的示例, 本发明实施例并不限于此, 任何配置至少两个服 务小区的方法均可以用于本发明实施例。
一个良务小区可以包括一个下行载波和与这个下行载波对应的一个上行载 波, 因此, 一对上行载波和下行载波又称为一个月良务小区, 本文不区分月良务小 区和载波。
此外, 本实施例以两个服务小区为例进行说明, 即一个主服务小区和一个 辅服务小区, 但是本发明实施例并不限于两个服务小区。 如果有更多的辅服务 小区, 可以采用同样的方法。
此外, 本实施例中的至少两个服务小区可以在工作不同的频点, 也可以是 在工作在相同的频点, 下文均与此相同。
步骤 320, 根据所述下行控制信道选择标识信息。
其中, 所述标识信息用于生成所述下行控制信道对应的所述物理上行控制 信道。 其中, 针对不同的服务小区, 选择不同的标识信息。
例如, 本步骤可以包括:
如果所述 UE只接收到所述辅服务小区对应的下行控制信道调度的下行数 据, 而没有接收到所述主服务小区对应的下行控制信道调度的下行数据, 所述
UE选择第二标识信息; 和 /或
如果所述 UE接收到的所述下行数据包括所述主服务小区对应的下行控制 信道调度的下行数据,即所述 UE只接收到所述主服务小区对应的下行控制信道 调度的下行数据, 或者, 所述 UE同时接收到所述主服务小区和一个或多个辅服 务小区对应的下行控制信道调度的下行数据, 所述 UE选择第一标识信息。
进一步地,所述第一标识信息可以为所述主服务 d、区对应的小区标识信息。 如果所述 UE只接收到一个辅服务小区对应的下行控制信道调度的下行数 据, 所述第二标识信息可以为所述一个辅服务小区对应的小区标识信息; 或者 如果所述 UE只接收到所述至少一个辅服务小区中的多个辅服务小区对应 的下行控制信道调度的下行数据, 所述 UE选择第二标识信息的步骤包括: 所述 UE按照预定规则选择所述第二标识信息。
其中, 所述小区标识信息可以为小区标识和 /或虚拟小区标识。
具体的, 本实施例中的服务小区对应的小区标识可以是与该服务小区的同 步信号对应的物理小区标识, 服务小区的虚拟小区标识可以是网络设备通过 RRC信令为 UE配置的一个标识 X, 该标识 X的取值范围可以跟上述物理小区 标识的取值范围相同, 例如从 0到 503中的整数。
一个示例中, 所述第一小区标识信息和第二小区标识信息可以分别为主服 务小区的小区标识和辅服务小区的小区标识。 假设 UE通过该主服务小区接入 LTE***,该 UE可以通过检测主服务小区的同步信道获取到主服务小区的小区 标识; 之后网络设备通过 RRC信令为该 UE添加了一个辅服务小区, 例如微基 站的载波 f2, 那么网络设备就通过该 RRC信令将该辅服务小区的小区标识发送 给该 UE, 或者 UE也可以通过检测该辅服务小区的同步信道获取其小区标识。
另一个示例中, 第二小区标识信息可以为虚拟小区标识, 第一'■!、区标识信 息可以为小区标识, 也可以为虚拟小区标识。 本示例以第二小区标识信息为虚 拟小区标识为例进行说明。 如图 3a所示, 假设主服务小区对应的小区标识为标 识 X; 宏基站的覆盖范围内有多个微基站 (载波为 f2), 如果这些微基站对应的小 区标识相同(当然也可以不同), 网络设备可以为 UE配置这些敖基站对应的虚 拟小区标识, 即第二小区标识信息, 从而使得多个微基站间干扰随机化。 其中, 网络设备可以通过 RRC信令将虚拟小区标识配置给 UE, 假设虚拟小区标识为 Xi, 其中 i是各微基站的标号。
需要说明的是, 本发明实施例中所述的标识信息并不限于上述示例, 还可 以是网络设备为所述 UE配置的标识的信息, 其中, 所述标识对于不同的服务小 区可以是不同的, 如, 主月良务小区对应一个标识, 辅月良务小区对应一个标识。 当然, 所述标识信息还可以是其他的标识信息, 只要能够区分服务小区即可。
步骤 330,所述 UE利用所选择的小区标识信息生成所述下行数据对应的物 理上行控制信道。
当网络设备为 UE配置了一个主服务小区和一个辅服务小区后, UE就要分 别监测这两个服务小区上的下行控制信道, 以通过这两个服务小区接收下行数 据。本实施例以下行控制信道为 PDCCH进行说明, 当然下行控制信道也可以是 基于 UE特定参考信号的 ePDCCH。这里假设宏基站的主服务小区和微基站的一 个辅服务小区对所述 UE是独立调度的, 会出现如下几种情况:
1 ) UE只收到主服务小区的 PDCCH;
2 ) UE只收到辅服务小区的 PDCCH;
3 ) UE同时收到主服务小区的 PDCCH和辅服务小区的 PDCCH。
如果 UE在某个时刻只能在一个上行载波上发送 PUCCH, 例如, UE在某 个时刻只能在主服务小区对应的上行载波上发送 PUCCH, 或者, UE在某个时 刻只能在辅服务小区对应的上行载波上发送 PUCCH, 或者 UE在某些时刻只能 在主服务小区对应的上行载波上发送 PUCCH, 在另一些时刻只能在辅服务小区 对应的上行载波上发送 PUCCH, 等等;
那么上述情况 1 )可以是只有宏基站调度 UE, 此时, 只有宏基站要接收
PUCCH, 情况 2 )可以是没有宏基站调度 UE, 只有微基站要接收 PUCCH, 情 况 3 )下两个基站都要接收 PUCCH。 针对情况 3 ) , 考虑到 UE距离宏基站一般 来说较微基站较远,则 UE在发送 PUCCH时所使用的功率需要满足能够使宏基 站可以接收到所述 PUCCH。 为了不对宏基站服务的其他 UE (如图 3a中的单载 波 UE3 )造成影响, 本发明实施例中该 UE要用宏基站的小区标识 X 来生成 PUCCH的基序列。 由于主服务小区对应的基序列是由相同的小区标识 X生成, 因此, 被宏基站服务的 UE向宏基站发送 PUCCH时使用的基序列都是相同的, 从而被宏基站服务的所有 UE向宏基站发送的 PUCCH可以正交, 因此各个 UE 向宏基站发送的 PUCCH没有干扰。 同理, 对于情况 1 ) , 该 UE也要用 X来生 成 PUCCH。 而对于情况 2 ) , 该 UE需要使用微基站的小区标识或虚拟小区标 识 Xi来生成对应的 PUCCH,这样可以在多个微基站使用相同的 PUCCH信道资 源时, 利用各个微基站的各自不同的 Xi来做到干扰随机化, 也可以在宏基站和 微基站使用相同的 PUCCH信道资源时, 实现发送 PUCCH的 UE之间的干扰随 机化。例如,如图 3a所示,如果 UE1和 UE2都只收到各自敖基站发送的 PDCCH, UE1和 UE2会分别用各自微基站的小区标识 XI和 X2来生成对应的 PUCCH, 这样实现了多个微基站间的 PUCCH干扰随机化; 或者, 如果 UE1收到宏基站 的 PDCCH, 而 UE2只收到微基站的 PDCCH, 则 UE1会用 UE1的宏基站的小 区标识 X生成 PUCCH,与潜在的其他发向宏基站的 UE的 PUCCH做到正交化, 而 UE2会用微基站的小区标识 X2生成 PUCCH, 这样, 在相同 PUCCH信道资 源上, UE1用较大功率发来的 PUCCH与 UE2自己发送的 PUCCH也能够实现 干扰随机化。
步骤 340, 在所述物理上行控制信道的信道资源上, 所述 UE发送所述物理 上行控制信道。
本步骤中, 所述 UE获取了 PUCCH信道资源, 并生成了 PUCCH之后, 就 在该信道资源上发送该 PUCCH给网络设备, 即宏基站和 /或微基站。
通过采用本实施例的方法, 由于 UE发送的物理上行控制信道是使用相应 的小区标识信息生成的, 这样, 在收到上述物理上行控制信道之后, 向 UE发送 了下行控制信道的网络设备能够根据使用的小区标识信息区分出对应的物理上 行控制信道, 实现了多个网络设备间复用相同的 PUCCH信道资源, 而不需要实 时获知其他基站的下行数据的调度情况, 达到了小区***的增益, 提高了 PUCCH信道资源的利用率。 同时, 通过使用物理上行控制信道是使用相应的小 区标识信息生成的, 还实现了 PUCCH干扰随机化。
此外,如果网络设备为 UE配置了多个辅服务小区,所述 UE按照预定规则 选择所述第二小区标识信息。 本实施例可以有多种预定规则。
例如, 所述 UE选择所述多个辅服务小区中的任一辅服务小区对应的小区 标识信息作为所述第二小区标识信息, 此时, 发送了下行数据的辅服务基站使 用所有可能使用的小区标识信息检测 PUCCH。
又如, 所述 UE选择所述主服务小区对应的网络设备通知的小区标识信息 作为所述第二小区标识信息。
又如, 所述 UE选择所述至少一个辅服务小区对应的公共的小区标识信息 作为所述第二小区标识信息。 该公共的小区标识信息可以是网络设备下发给 UE 的一个虚拟小区标识, 即使有多个辅服务小区的调度, 或者, 如果这些微基站 对应的小区标识相同, 该公共的小区标识信息也可以是这些微基站对应的这一 相同的小区标识等, 本发明实施例并不限于这些方式, 还可以是其他的公共的 小区标识。
当然, 本发明实施例并不限于此, 还可以是其他的预定规则。
上述实施例中, 所述下行数据对应的物理上行控制信道的信道资源可以有 多种。
一个实现方式中, 如果 UE收到主服务小区对应的 PDCCH和 /或辅服务小 区对应的 PDCCH, 使用网络设备通知的或预存的一个或一组 PUCCH信道资源 来反馈 PUCCH。 这种情况下, 不论 UE收到的是主服务小区对应的 PDCCH调 度的下行数据还是辅服务小区对应的 PDCCH调度的下行数据, 还是二者都收 到,所述 UE均使用主服务小区对应的网络设备通知的一个或一组 PUCCH信道 资源。 该一个或一组 PUCCH信道资源也可以由辅服务小区对应的网络设备通 知。其中,预存的一个或一组 PUCCH信道资源可以是在接收到网络设备通知的 一个或一组 PUCCH信道资源后存储的一个或一组 PUCCH信道资源。下文的实 施例与此相同。
该一个或一组 PUCCH信道资源是网络设备为所述 UE半静态配置的。具体 的, 网络设备可以通过 RRC信令向 UE通知该一个或一组 PUCCH信道资源。 其中,对于 PUCCH格式 3的反馈模式,所述 PUCCH信道资源就是一个 PUCCH 格式 3的信道资源;对于 PUCCH格式 lb结合信道选择的反馈模式,所述 PUCCH 信道资源是供信道选择的 PUCCH格式 lb信道资源中的一组 PUCCH格式 lb的 信道资源, 比如对于 M级( level M )的信道选择则该一组信道资源中包括 M个 PUCCH格式 lb的信道资源, 该 M可以取值 2, 3或 4, 其中, M的值具体取决 于服务小区对应的下行数据的传输模式, 对于时分复用 (TDD, time division duplexing ) ***, M 的取值还取决于一个绑定窗内的下行子帧的数目。 这样预 留一个或一组 PUCCH信道资源,使得实现较为筒单, 网络设备盲检测的信道资 源个数也较少。
另一实现方式中, 如果所述 UE只接收到所述主服务小区对应的下行控制 信道调度的下行数据, 所述信道资源为第一信道资源, 则所述信道资源是第一 信道资源; 和 /或, 如果所述 UE接收到的下行数据包含所述辅服务小区对应的 下行控制信道调度的下行数据, 则所述信道资源是第二信道资源。 其中, 所述 第一信道资源为所述主服务小区对应的下行控制信道的信道资源参数隐式对应 的所述物理上行控制信道的信道资源,如根据 CCE索引和 /或下行控制信道的天 线端口号, 或者, 根据 eCCE索引和 /或下行控制信道的天线端口号, 确定的信 道资源; 所述第二信道资源为所述主服务小区对应的网络设备通知的所述物理 上行控制信道的一个信道资源或一组信道资源。
另一个实现方式中, 如果所述 UE只接收到所述至少一个辅服务小区中的 一个辅服务小区对应的下行控制信道调度的下行数据, 所述信道资源为第一信 道资源; 和 /或,
如果所述 UE接收到的下行数据包括所述主服务小区对应的下行控制信道 调度的下行数据, 或者,如果所述 UE接收到的所述下行数据包括所述至少一个 辅服务小区中的多个辅服务小区对应的下行控制信道调度的下行数据, 所述信 道资源为第二信道资源;
其中, 所述第二信道资源为所述主服务小区对应的网络设备通知的所述物 理上行控制信道的一个信道资源或一组信道资源; 所述第一信道资源为所述一 个辅服务小区对应的下行控制信道的信道资源参数隐式对应的所述物理上行控 制信道的信道资源, 或者, 如果所述第二信道资源为一组信道资源, 所述第一 信道资源为所述一组信道资源中的一个信道资源。
另一个实现方式中, 如果所述 UE只接收到所述主服务小区的所述下行控 制信道调度的下行数据, 所述信道资源为第一信道资源; 其中, 所述第一信道 资源为所述主服务小区对应的下行控制信道的信道资源参数隐式对应的信道资 源; 或者
如果所述 UE接收到的下行数据包括所述至少一个辅服务小区中的多个辅 服务小区对应的下行控制信道调度的下行数据, 或者,如果所述 UE接收到的下 行数据包括所述主服务小区对应的下行控制信道调度的下行数据和一个或多个 辅服务小区对应的下行控制信道调度的下行数据, 所述信道资源为第三信道资 源; 所述第三信道资源为所述主服务小区对应的网络设备通知的所述物理上行 控制信道的一个信道资源或一组信道资源; 或者
如果所述 UE接收到所述至少一个辅服务小区中的一个辅服务小区对应的 下行控制信道调度的下行数据, 所述信道资源为第二信道资源, 其中, 所述第 二信道资源为所述至少一个辅服务小区中的所述一个辅服务小区对应的下行控 制信道的资源参数隐式对应的信道资源; 或者, 如果所述第三信道资源为所述 一组信道资源, 所述第二信道资源为所述一组信道资源中的一个信道资源。
其中, 所述一个信道资源或一组信道资源可以为所述主服务小区对应的网 络设备通过无线资源控制 RRC信令通知的。
通过上述几种实现方式, 在只收到辅服务小区的 PDCCH时, UE不用再去 执行信道选择, 而是用一个确定的信道资源来反馈 PUCCH, 减少了网络设备盲 检测不同信道的可能性, 可以优化 PUCCH性能。
进一步地, 如果所述 UE接收到的下行数据包括所述主服务小区对应的下 行控制信道调度的下行数据, 则该信道资源可以在主服务小区对应的上行载波 上。 当然该信道资源也可以放在辅服务小区对应的上行载波上, 只是可能会有 调度沖突。
如果所述 UE只接收到所述辅服务小区对应的下行控制信道调度的下行数 据, 所述信道资源位于所述辅服务小区对应的上行载波上。
同理, 如果所述 UE只接收到所述辅服务小区对应的下行控制信道调度的 下行数据, 所述信道资源位于辅服务小区对应的上行载波上; 当所述 UE同时接 收到主服务小区和辅服务小区对应的下行控制信道, 则该信道资源可以在主服 务小区对应的上行载波上或在辅服务小区对应的上行载波上。 其中, 如果所述 UE只接收到多个辅服务小区对应的下行控制信道调度的下行数据, 而没有接收 到所述主服务小区对应的下行控制信道调度的下行数据, 所述上行载波可以是 任一辅服务小区对应的上行载波。
相应地, 如果所述信道资源在主服务小区对应的上行载波上, 且 UE 同时 反馈了主服务小区对应的下行数据对应的 ACK或 NACK和辅服务小区对应的下 行数据对应的 ACK或 NACK,则调度主服务小区的第一网络设备和调度辅服务 小区的第二网络设备都需要在该上行载波上分别接收各自对应的 ACK 或 NACK。 进一步地, 利用所选择的小区标识信息生成所述下行数据对应的物理上行 控制信道, 可以包括:
对于格式 lb结合信道选择的反馈模式,所述所选择的小区标识信息用于生 成所述物理上行控制信道的序列; 和 /或
对于格式 3的反馈模式, 所述所选择的小区标识信息用于生成所述物理上 行控制信道的调制符号的循环移位图样和 /或正交扩频码的映射。
具体地, 对于格式 lb结合信道选择的反馈模式, 小区标识或虚拟小区标识 用于生成 PUCCH的基序列,从而相同的小区标识对应相同的基序列, 不同的小 区标识对应不同的基序列。使用相同的基序列生成的不同的 PUCCH信道之间可 以实现正交化, 而使用不同的基序列生成的 PUCCH之间是伪正交的, 因此利用 相同的 PUCCH信道资源而使用不同的基序列可以实现 PUCCH之间的干扰随机 化和资源复用。 确定了基序列后, 就可以根据 PUCCH信道资源, 来确定 lb格 式的 PUCCH的频域 ZC序列的循环移位和时域扩频码, 这样就生成了下行数据 对应的 PUCCH。
对于格式 3的反馈模式, 首先根据 PUCCH信道来确定正交扩频码, 之后 对调制符号进行扩频, 然后对扩频后的调制符号进行循环移位, 从而生成 PUCCH格式 3。 其中, 该循环移位的图样或规则是由小区标识或虚拟小区标识 来确定的, 这样, 利用不同的正交扩频码可以对 PUCCH格式 3的信道资源正交 化, 而对于相同的正交扩频码的 PUCCH资源, 可以采用不同的小区标识或虚拟 小区标识来对扩频后的调制符号进行循环移位, 这样可以实现 PUCCH格式 3 的信道资源的干扰随机化和资源复用。
NACK的编码比特, 现有技术中, 不论反馈的 PUCCH是什么情况, UE都是根 据主服务小区和辅服务小区上配置的下行数据的传输模式来确定的。 假设主服 务小区和辅服务小区调度的下行数据对应的 ACK或 NACK比特数都是 1 , 则 PUCCH格式 3机制下的 ACK或 NACK码本大小为 2, 即使某个时刻只调度了 辅服务小区, ACK或 NACK码本大小仍然为 2。 然而, 以 PUCCH格式 3为例, 如果总是按照主服务小区和辅服务小区上配置的下行数据的传输模式来确定 ACK或 NACK码本大小, 每次都需要按照最大的比特数传输 PUCCH。 因为宏 基站主要提供***信息和移动性管理等控制信息, 因此宏基站的调度机会较小, 而大量的调度机会都会发生在微基站上。这样,在宏基站和微基站间的 CA的场 景下,使用最大的比特数传输 PUCCH会导致传输效率低, 因此本发明实施例优 化了只有微基站调度时的码本大小设计。 具体的, 如果是格式 3 的反馈模式, 则如图 3所示, 本实施例的方法还可以包括:
步骤 311 ,如果所述 UE没有接收到所述主服务小区对应的下行控制信道调 度的下行数据, 根据所述辅服务小区的对应的下行控制信道调度的所述下行数 据的传输模式确定所述物理上行控制信道的码本大小; 或者,如果所述 UE接收 到所述主服务小区对应的下行控制信道调度的下行数据, 根据所述主服务小区 和所述辅服务小区的下行数据的传输模式来确定所述物理上行控制信道的所述 码本大小。
如上所述, 如果所述 UE只接收到所述辅服务小区对应的下行控制信道调 度的下行数据, 则 UE 只根据辅服务小区上配置的下行数据的传输模式确定 PUCCH的码本大小, 这样确定出来的码本大小是一个小码本。 而如果所述 UE 接收到所述主服务小区对应的下行控制信道调度的下行数据,该 UE会根据所述 主服务小区和所述辅服务小区上配置的下行数据的传输模式来确定所述物理上 行控制信道的码本大小, 这样确定出来的码本大小是一个大码本, 因此, 这两 种情况下 UE所反馈的 PUCCH的码本大小不同, 从而会提高 PUCCH的传输效 率。 对于多个辅服务小区的情况, 各个辅服务小区是独立的, 因此, 确定出来 的码本大小是各个辅服务小区上配置的各个传输模式对应的码本大小之和。 而 如果所述 UE接收到所述主服务小区的下行数据以及多个辅服务小区的下行数 据, 确定出来的码本大小是所述主服务小区以及所述多个辅服务小区上配置的 传输模式对应的码本大小之和。
需要说明的是, 本步骤 311可以是在步骤 310之后, 步骤 340之前的任何 两个步骤之间执行。 网络设备侧可以用不同的小区标识信息确定不同的码本大小, 从而可以优 化 UE只收到辅服务小区对应的下行调度的情况下的码本大小设计,提高了接收 ACK或 NACK的性能。 进一步地, 步骤 340中, 所述 UE在所述信道资源上发送所述物理上行控 制信道, 可以包括:
所述 UE 根据路径损耗和所述下行控制信道中的发送功率控制(TPC , transmit power control)命令来确定所述物理上行控制信道的发送功率, 并以所述 确定的发送功率来发送所述物理上行控制信道。
具体的, 如果所述 UE接收到的所述下行数据不包括所述主服务小区的下 行控制信道调度的下行数据, 所述 TPC命令为所述下行数据对应的一个辅服务 小区或多个辅服务小区中的一个辅服务小区的下行控制信道中的 TPC命令; 或 如果所述 UE接收到的下行数据包括所述主服务小区的下行控制信道调度 的下行数据, 所述 TPC命令为所述主服务小区的下行控制信道中的 TPC命令。
其中, 所述路径损耗可以是预定的一个值。
或者, 具体地, 如果所述 UE只接收到所述辅服务小区对应的下行控制信 道调度的下行数据, 所述路径损耗为第一路径损耗; 和 /或, 如果所述 UE接收 到的下行数据包括所述主服务小区对应的下行控制信道调度的下行数据服务小 区对应的下行, 则所述路径损耗为第二路径损耗;
其中,
如果所述 UE在所述主服务小区对应的上行载波上发送所述物理上行控制 信道, 则所述第二路径损耗是通过所述主服务小区发送的下行参考信号的功率 和所述 UE测量到的所述下行参考信号的接收功率确定的, 其中, 所述下行参考 信号的接收功率即参考信号参考功率 (RSRP, reference signal reference power); 所述第一路径损耗是通过所述辅服务小区发送的下行参考信号的功率、 所述 UE 测量到的所述下行参考信号的接收功率以及功率偏移量来确定的; 如果所述 UE在所述辅服务小区对应的上行载波上发送所述物理上行控制 信道, 则所述第二路径损耗是通过所述主服务小区发送的下行参考信号的功率、 所述 UE测量到的所述下行参考信号的接收功率以及功率偏移量来确定的;所述 第一路径损耗是通过所述辅服务小区发送的下行参考信号的功率和所述 UE 测 量到的所述下行参考信号的接收功率来确定的。
另一个实施例是, 所述主服务小区的下行控制信道中的所述 TPC命令的值 为第一 TPC命令值; 所述辅服务小区的下行控制信道中的发送功率控制 TPC命 令的值为第二 TPC命令值, 所述第一 TPC命令值与所述第二 TPC命令值的差 为功率偏移量, 其中, 所述第一 TPC命令值在所述主服务小区的下行控制信道 中的所述 TPC命令的取值集合中的位置与所述第二 TPC命令值在所述辅服务小 区的下行控制信道中的所述 TPC命令的取值集合中的位置相同。
具体的, 如果所述 UE接收到的下行数据不包括所述主服务小区对应的下 行控制信道调度的下行数据, 所述 TPC命令为第一 TPC命令, 所述路径损耗值 为第一路径损耗值; 和 /或, 如果所述 UE接收到的下行数据包括所述主服务小 区对应的下行控制信道调度的下行数据服务小区对应的下行数据, 所述 TPC命 令为第二 TPC命令, 所述路径损耗值为第二路径损耗值。
具体地, 所述第一路径损耗通过所述辅服务小区发送的下行参考信号的功 率和所述 UE测量到的所述下行参考信号的接收功率确定的;所述第二路径损耗 通过所述主服务小区发送的下行参考信号的功率和所述 UE 测量到的所述下行 参考信号的接收功率确定的; 所述第一 TPC命令的取值集合和所述第二 TPC命 令的取值集合中对应的元素取值至少有一个是不同的, 且相差一个功率偏移量。
举例说明, 假设所述 UE在所述主服务小区对应的上行载波上发送所述物 理上行控制信道, 且第二 TPC命令的取值集合为 {-1 , 0, 1 , 3 }dB, 此时表示如 果所述 UE接收到的下行数据包括所述主服务小区对应的下行控制信道调度的 下行数据服务小区对应的下行数据,所述 UE可以用所述第二路径损耗和所述第 二 TPC命令的取值集合中的某个取值来确定 PUCCH的发送功率; 第一 TPC命 令的取值集合可以为 {-3, 0, 1 , 6}dB, 可以看出其与第二 TPC命令的取值集合 中的对应元素有两个取值是不同的, 当然其他取值也不排除, 这个对应取值之 间的差可以看作一个功率偏移量, 来补偿所述主服务小区和所述辅服务小区所 在频点造成的路径损耗的功率差。
本发明实施例中, 所述功率偏移量可以为所述主服务小区和所述辅服务小 区所在频点造成的路径损耗的功率差, 但不限于此, 还可以是根据其他需求设 置的一个功率偏移量。
通过采用上述方案, 在 UE距离微小区比宏小区近的多的情况下, 保证了 只向微小区发送的物理上行控制信道, 用微小区的路径损耗和 TPC命令计算发 送功率, 这样发送功率会比向宏小区发送的发送功率低。 因此, 该方案可以根 据向不同的发送点以各自的功率发送物理上行控制信道, 来提升功率效率, 降 低对其他 UE和基站造成干扰。
步骤 350, 如果所述主服务小区对应的网络设备向所述 UE发送了下行数 据,主服务小区对应的网络设备在为所述 UE分配的用于反馈物理上行控制信道 的信道资源上, 使用主服务小区对应的标识信息检测所述下行数据对应的所述 物理上行控制信道, 其中, 所述物理上行控制信道是所述 UE使用所述主服务小 区对应的标识信息生成的。
进一步地, 步骤 340之前, 所述方法还可以包括:
步骤 331 ,所述主服务小区的网络设备向所述 UE和为所述 UE配置的所有 辅服务小区对应的网络设备, 通知所述物理上行控制信道的一个信道资源或一 组信道资源。

其中, 本发明所有实施例中的所述网络设备均可以^^站或无线网络控制 器等网络设备。
具体地, 所述检测所述下行数据对应的物理上行控制信道, 包括: 在所述一个信道资源或一组信道资源以及所述下行控制信道隐式对应的所 述物理上行控制信道的信道资源上, 使用所述小区标识信息检测所述下行数据 对应的物理上行控制信道。
进一步地, 所述检测所述下行数据对应的物理上行控制信道, 包括: 在所述主服务小区对应的上行载波上检测所述下行数据对应的物理上行控 制信道。
步骤 360,如果辅服务小区对应的网络设备向所述 UE发送了下行数据, 所 述辅服务小区对应的网络设备在用于反馈物理上行控制信道的信道资源上, 使 用所述可能使用的小区标识信息检测所述下行数据对应的物理上行控制信道, 其中,所述物理上行控制信道是所述 UE使用所述可能使用的小区标识信息中的 一个小区标识信息生成的。
需要说明的是, 步骤 350与步骤 360的执行顺序可以是任意的, 如, 可以 是同时执行, 也可以是先后执行。
其中, 所述 UE可能使用的小区标识信息包括:
所述 UE可能使用的标识信息包括所述主服务小区对应的小区标识信息, 所述网络设备对应的所述辅服务小区对应的小区标识信息, 和按照预定规则确 定的标识信息; 或者
所述 UE可能使用的标识信息包括所述主服务小区对应的小区标识信息和 为所述 UE配置的所有辅服务小区对应的小区标识信息。
其中, 所述按照预定规则确定的小区标识信息包括:
所述主服务小区对应的网络设备通知的小区标识信息; 或者
为所述 UE配置的所有辅服务小区对应的公共的小区标识信息, 其中, 所 述公共的小区标识信息可参见上述实施例中的描述, 此处不再赘述。

一种实现方式中, 所述获取所述物理上行控制信道的一个信道资源或一组 信道资源的信息, 可以包括: 通过 RRC信令获取所述一个信道资源或所述一组 信道资源的信息。
另一种实现方式中, 所述获取所述物理上行控制信道的一个信道资源或一 组信道资源之前, 所述方法还可以包括: 通过 RRC信令接收所述一个信道资源 或所述一组信道资源的信息, 并存储所述一个信道资源或所述一组信道资源的 所述信息;
所述获取所述物理上行控制信道的一个信道资源或一组信道资源的信息, 可以包括: 获取所述存储的信息。
通过采用本实施例的方法, 由于 UE发送的物理上行控制信道是使用相应 的小区标识信息生成的, 这样, 在收到上述物理上行控制信道之后, 向 UE发送 了下行控制信道的主服务小区对应的网络设备能够根据该小区标识信息区分出 对应的物理上行控制信道, 实现了多个网络设备间复用相同的 PUCCH信道资 源, 而不需要实时获知其他 eNB的 PUCCH信道资源的调度情况, 达到了小区 ***的增益, 提高了 PUCCH信道资源的利用率。 同时, 通过上述实施例, 辅服 务小区对应的基站减少了盲检测不同信道的可能性, 可以优化 PUCCH性能。 本发明另一实施例提供了一种上行控制信道发送方法, 如图 4所示, 所述 方法包括如下步骤。
步骤 410, UE接收网络设备通过一个或多个下行控制信道调度的下行数据, 其中, 所述下行控制信道为一个或多个服务小区对应的下行控制信道, 所述一 个或多个服务小区是为所示 UE配置的至少两个服务小区中的服务小区,所述至 少两个服务小区包括一个主服务小区和至少一个辅服务小区。

步骤 430, 根据所述下行控制信道中的 TPC命令和路径损耗值, 所述 UE 确定所述物理上行控制信道的发送功率, 并以所述确定的发送功率来发送所述 物理上行控制信道。
具体的, 如果 UE只收到辅服务小区的下行控制信道调度的下行数据, 没 有收到主服务小区的下行控制信道调度的下行数据, 用辅服务小区的下行控制 信道中的 TPC命令和路径损耗来确定所述 PUCCH的发送功率; 和 /或
如果所述 UE收到的下行数据包括所述主服务小区的下行控制信道调度的 下行数据, 用所述主服务小区的下行控制信道中的 TPC命令和路径损耗来确定 PUCCH的发送功率。
其中, 如果是只收到多个辅服务小区的下行控制信道调度的下行数据, 没 有收到主服务小区的下行控制信道调度的下行数据, 用任一个辅服务小区的下 行控制信道中的 TPC命令和路径损耗来确定所述 PUCCH的发送功率均可以。 进一步地,如果所述 UE只接收到所述辅服务小区对应的下行控制信道调度的下 行数据, 所述路径损耗值为第一路径损耗值; 和 /或, 如果所述 UE接收到的下 行数据包括所述主服务小区对应的下行控制信道调度的下行数据服务小区对应 的下行, 则所述路径损耗值为第二路径损耗值;
具体地,
如果所述 UE在所述主服务小区对应的上行载波上发送所述物理上行控制 信道, 则所述第二路径损耗是通过所述主服务小区发送的下行参考信号的功率 和所述 UE测量到的所述下行参考信号的接收功率确定的, 其中, 所述下行参考 信号的接收功率即参考信号参考功率 (RSRP, reference signal reference power); 所述第一路径损耗是通过所述辅服务小区发送的下行参考信号的功率、 所述 UE 测量到的所述下行参考信号的接收功率以及功率偏移量来确定的;
如果所述 UE在所述辅服务小区对应的上行载波上发送所述物理上行控制 信道, 则所述第二路径损耗是通过所述主服务小区发送的下行参考信号的功率、 所述 UE测量到的所述下行参考信号的接收功率以及功率偏移量来确定的;所述 第一路径损耗是通过所述辅服务小区发送的下行参考信号的功率和所述 UE 测 量到的所述下行参考信号的接收功率来确定的。
另一实现方式中, 所述主服务小区的下行控制信道中的所述 TPC命令的值 为第一 TPC命令值; 所述辅服务小区的下行控制信道中的发送功率控制 TPC命 令的值为第二 TPC命令值, 所述第一 TPC命令值与所述第二 TPC命令值的差 为功率偏移量, 其中, 所述第一 TPC命令值在所述主服务小区的下行控制信道 中的所述 TPC命令的取值集合中的位置与所述第二 TPC命令值在所述辅服务小 区的下行控制信道中的所述 TPC命令的取值集合中的位置相同。
具体的, 如果所述 UE接收到的下行数据不包括所述主服务小区对应的下 行控制信道调度的下行数据, 所述 TPC命令为第一 TPC命令, 所述路径损耗值 为第一路径损耗值; 和 /或, 如果所述 UE接收到的下行数据包括所述主服务小 区对应的下行控制信道调度的下行数据服务小区对应的下行数据, 所述 TPC命 令为第二 TPC命令, 所述路径损耗值为第二路径损耗值。
具体地, 所述第一路径损耗通过所述辅服务小区发送的下行参考信号的功 率和所述 UE测量到的所述下行参考信号的接收功率确定的;所述第二路径损耗 通过所述主服务小区发送的下行参考信号的功率和所述 UE 测量到的所述下行 参考信号的接收功率确定的; 所述第一 TPC命令的取值集合和所述第二 TPC命 令的取值集合中对应的元素取值至少有一个是不同的, 且相差一个功率偏移量。
举例说明, 假设所述 UE在所述主服务小区对应的上行载波上发送所述物 理上行控制信道, 且第二 TPC命令的取值集合为 {-1 , 0, 1 , 3 }dB, 此时表示如 果所述 UE接收到的下行数据包括所述主服务小区对应的下行控制信道调度的 下行数据服务小区对应的下行数据,所述 UE可以用所述第二路径损耗和所述第 二 TPC命令的取值集合中的某个取值来确定 PUCCH的发送功率; 第一 TPC命 令的取值集合可以为 {-3, 0, 1 , 6}dB, 可以看出其与第二 TPC命令的取值集合 中的对应元素有两个取值是不同的, 当然其他取值也不排除, 这个对应取值之 间的差可以看作一个功率偏移量, 来补偿所述主服务小区和所述辅服务小区所 在频点造成的路径损耗的功率差。
本发明实施例中, 所述功率偏移量可以为所述主服务小区和所述辅服务小 区所在频点造成的路径损耗的功率差, 但不限于此, 还可以是根据其他需求设 置的一个功率偏移量。
通过采用上述方案, 在 UE距离微小区比宏小区近的多的情况下, 保证了 只向微小区发送的物理上行控制信道, 用微小区的路径损耗和 TPC命令计算发 送功率, 这样发送功率会比向宏小区发送的发送功率低。 因此, 该方案可以根 据向不同的发送点以各自的功率发送物理上行控制信道, 来提升功率效率, 降 低对其他 UE和基站造成干扰。
