虽然采用隐性映射的方式指示用于传输PUCCH的资源，可以节省信令开销，但将该方式应用于5G***中存在一系列的问题。首先，由于5G***的PUCCH分布在多个子带中，且多个下行时隙的PDCCH可能映射到一个上行时隙的PUCCH中，将所有的PDCCH资源分别映射到每个PUCCH的子带中，会造成每个PUCCH的子带中只有少量资源被使用，剩下的可用于传输物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)的时频资源会被PUCCH分割成凌乱的资源碎片，将大大增加PUSCH的调度复杂度，降低资源利用效率。其次，隐性映射的方式无法利用频率选择性调度的性能增益，使PUCCH的性能受到影响。最后，5G***中上行频域资源可能是变化的，这使得从用于传输PDCCH的资源到用于传输PUCCH的资源的映射关系可能会发生变化，固定的映射关系难以适应动态调整的资源映射。
另外一种方案中提出，用于传输PUCCH的频域资源可以由PDCCH动态调度。例如，通过无线资源控制(Radio Resource Control，RRC)信令和/或下行控制信息(Downlink Control Information，DCI)显性指示PUCCH用 于传输PUCCH的频域资源。然而，虽然采用PDCCH动态调度用于传输PUCCH的频域资源的方式能够利用频率选择性调度改善PUCCH链路性能，提高上行资源利用效率，但是完全地动态调度会造成网络设备的实现复杂度大，信令开销大的问题。

具体实施方式
下面将结合附图，对本发明实施例中的技术方案进行描述。
图1给出了本发明实施例应用的一种通信***的示意图。如图1所示，网络100可以包括网络设备102以及终端设备104、106、108、110、112和114，其中，网络设备与终端设备之间通过无线连接。应理解，图1仅以网络包括一个网络设备为例进行说明，但本发明实施例并不限于此，例如，网络还可以包括更多的网络设备；类似地，网络也可以包括更多的终端设备，并且网络设备还可以包括其它设备。
本发明结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，简称为“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
本发明结合网络设备描述了各个实施例。网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(Evolutional Node B，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等。
通信***中，控制信道通常有两种，一种是公共控制信道，一种是终端 设备配置(UE-specific)控制信道。公共控制信道是用来与所有终端设备或一部分终端设备传输公共信息的控制信道。终端设备配置控制信道是用来与指定的终端设备传输相关控制信息的控制信道，比如有关数据传送的配置信号等。本发明实施例的技术方案可以应用于传输终端设备配置控制信道中的上行控制信道。
在通信***中，控制区域又称控制资源集(control resource set)，按照上行和下行，分为上行控制区域和下行控制区域。与4G***不同，在5G***中，控制区域不再按照时频维度进行划分，而是将时域和频域两个维度分开，时域控制区域和频域控制区域分别单独讨论。
频域控制区域不是涵盖整个***带宽，而只是涵盖其中一部分频域资源。频域控制区域可以由若干在频域上连续或非连续的物理资源块(Physical Resource Block，PRB)或者称为资源块(Resource Block，RB)组成。PRB或RB是频域上最小的调度单元，称为频域调度单元。应理解，除PRB或RB以外，频域调度单元还可以是其他粒度的频域单元，本发明实施例对此不作限定。时域控制区域由若干在时域上连续或非连续的时域调度单元组成。时域调度单元是时域上最小的调度单元，可以是时隙、子帧、帧或者一个或多个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号等。
一个控制信道可以用一个或几个控制信道元素(Control Channel Element，CCE)来传送，如使用1,2,4,8,…个控制信道元素来传送，这也称为控制信道元素聚合等级(CCE Aggregation Level，CCE AL)。一个控制信道元素又可以由几个控制资源单元(control resource unit)构成，一个控制资源单元是由频域上的一个PRB和时域上的一个时隙(或几个OFDM符号)组成的一个时频资源(time-frequency resource)，它可以看成是控制信道传输所使用的最小资源单元。
特定的下行时域控制区域和下行频域控制区域可以构成下行时频区域。除下行时域资源和下行频域资源以外，下行时频区域还可以包括特定的码域资源和/或波束域资源，不同下行时频区域在时域、频域、码域和/或波束域上可以有部分重叠，本发明实施例对此不做限定。同理，特定的上行时域控制区域和上行频域控制区域可以构成上行时频区域。除上行时域资源和上行频域资源以外，上行时频区域还可以包括特定的码域资源和/或波束域资源， 不同上行时频区域在时域、频域、码域和/或波束域上可以有部分重叠，本发明实施例对此不做限定。
应理解，本发明各实施例的位置，例如上行频域调度单元的位置是指该上行频域调度单元在相应的上行频域控制区域中的相对位置，下行频域控制区域的位置是指该下行频域控制区域在相应的下行时域调度单元的所有频域控制区域中的相对位置。上行控制信道的位置可以包括其在时域、频域、码域和波束域的具***置，本发明各实施例主要关注时域和频域。
还应理解，通常而言，上行时频资源中不用于传输上行控制信道的时频资源可用于传输上行数据。
图2是本发明一个实施例的传输上行控制信道的方法200的示意性流程图。方法200可以由网络设备执行，该方法包括：
S210，网络设备在第一下行频域控制区域上，向终端设备发送下行控制信道，下行控制信道中包括第一配置信息，第一配置信息用于动态地指示终端设备向网络设备发送上行控制信道所使用的至少一个第一上行频域控制区域；
S220，网络设备在至少一个第一上行频域控制区域中每个第一上行频域控制区域的第一上行频域调度单元上，接收终端设备发送的上行控制信道，第一上行频域调度单元在第一上行频域控制区域中的频域位置是根据第一下行频域控制区域确定的。
本发明实施例的传输上行控制信道的方法，通过第一配置信息指示上行频域控制区域，通过下行频域控制区域的位置确定用于传输上行控制信道的上行频域调度单元在上行频域控制区域中的位置，采用动态调度和隐性指示相结合的方式，确定传输上行控制信道的频域资源，可以降低PUSCH的调度复杂度，信令开销小，网络设备的调度复杂度低。
应理解，本发明实施例的至少一个第一上行频域控制区域可以全部位于同一个上行时域调度单元；也可以分别位于不同的上行时域调度单元；还可以是一部分第一上行频域控制区域位于同一个上行时域调度单元，另一部分位于其他的上行时域调度单元，本发明实施例会在下文详细展开描述。
在本发明各实施例中，上行频域控制区域是通过第一配置信息动态调度的，网络设备可以根据当前各频带的信道状况灵活选取上行频域控制区域。因为在一个频带(一个上行频域控制区域)中，各上行频域调度单元的信道 状况差别不大，因此不再进行动态调度，而是通过发送下行控制信道的下行频域控制区域的位置隐性映射。
还应理解，本发明实施例不使用完全的隐性指示方式，不需要像现有的隐性指示方式方案一样，将所有可能会传输上行控制信道的频率资源均设置为上行频域控制区域，这样可以节省资源，提高资源利用效率。此外，为了能够利用频率选择性调度提高上行控制信道的链路性能，上行频域控制区域所占用的频带可以根据***的需要灵活调整。例如，可以将上行频域控制区域设置在尽量均匀的分散在整个工作频带中，能够利用频率选择性调度提高上行控制信道的链路性能。
下面结合几种具体的场景对本发明实施例的传输上行控制信道的方法进行详细的描述。
图3示出了本发明一个实施例的传输上行控制信道的方法的示意图。在该具体的场景中，如图3所示，***中一个下行时域调度单元(例如下行时隙)固定对应一个上行时域调度单元(例如上行时隙)。在该情况下，用于传输上行控制信道的资源一定在上行时域调度单元上，只需确定资源的频域位置即可。
假设下行时隙中包括S(S＝4)个下行频域控制区域，下行频域控制区域1、下行频域控制区域2、下行频域控制区域3和下行频域控制区域4。网络设备在4个下行频域控制区域中的下行频域控制区域s(s＝3)向终端设备发送下行控制信道。图3中示出了两个终端设备，终端设备1和终端设备2，其下行控制信道均在下行频域控制区域3发送。
假设上行时隙中包括T(T＝3)个上行频域控制区域，上行频域控制区域1、上行频域控制区域2和上行频域控制区域3。本发明实施例的频域资源设计为，每个上行频域控制区域上设置S个上行频域调度单元，以与S个下行频域控制区域对应。
对于终端设备1，网络设备在下行频域控制区域3上，向终端设备1发送的下行控制信道中包括第一配置信息，第一配置信息包括终端设备1的上行控制信道所使用的上行频域控制区域的信息，例如在图3的例子中为上行频域控制区域2。该终端设备1的上行控制信道所使用的上行频域调度单元由映射关系f(s)确定，这里f(s)＝s，即使用上行频域控制区域2的4个上行频域调度单元中的上行频域调度单元3来传输上行控制信道。
对于终端设备2，网络设备在下行频域控制区域3上，向终端设备2发送的下行控制信道中包括第一配置信息，第一配置信息包括终端设备2的上行控制信道所使用的上行频域控制区域的信息，例如在图3的例子中为上行频域控制区域3。该终端设备2的上行控制信道所使用的上行频域调度单元由映射关系f(s)确定，这里f(s)＝s，即使用上行频域控制区域3的4个上行频域调度单元中的上行频域调度单元3来传输上行控制信道。
网络设备可通过高层信令，例如RRC信令等配置下行频域控制区域对应的上行频域调度单元的映射关系f(s)。例如，该映射上行频域调度单元的方式是对下行时隙的多个下行频域控制区域进行编号，也对每个上行频域控制区域中的上行频域调度单元进行编号，下行频域控制区域的编号即为上行频域调度单元的编号。一种具体的指示上行频域控制区域的方式是对上行时隙的多个上行频域控制区域进行编号，在第一配置信息中指示该编号。概括而言，第一上行频域调度单元在第一上行频域控制区域中的位置是根据第一下行频域控制区域在第一下行时域调度单元中的频域位置确定的。
应理解，图3示出的示意图中，第一配置信息仅指示了一个第一上行频域控制区域。在本发明的实施例中，第一配置信息可以指示上行时隙中多个第一上行频域控制区域。
还应理解，图3示出的示意图中一个下行时域调度单元固定对应一个上行时域调度单元。在其他场景中，一个下行时域调度单元可以固定对应多个上行时域调度单元；或者，一个下行时域调度单元可以根据***需求，选择性地对应多个上行时域调度单元中某一个上行时域调度单元。此时，还需要指示出，进行上行控制信道的传输所占中的时域资源，即需要指示出在哪个上行时域调度单元上传输上行控制信道。
可选地，下行控制信道中还包括第二配置信息，第二配置信息用于指示至少一个第一上行时域调度单元，S220网络设备在至少一个第一上行频域控制区域中每个第一上行频域控制区域的第一上行频域调度单元上，接收终端设备发送的上行控制信道，可以包括：网络设备在至少一个第一上行时域调度单元中对应的第一上行频域控制区域中的第一上行频域调度单元上，接收终端设备发送的上行控制信道。
图4示出了本发明另一个实施例的传输上行控制信道的方法的示意图。在该具体的场景中，如图4所示，***中一个下行时域调度单元(例如下行 时隙)对应两个上行时域调度单元(例如上行时隙1和上行时隙2)。网络设备在下行频域控制区域3上，向终端设备发送下行控制信道。下行控制信道中除了用第一配置信息指示上行频域控制区域2以外，还包括第二配置信息，第二配置信息用于指示上行控制信道在上行时隙1上发送。最终，使用上行时隙1的上行频域控制区域2的4个上行频域调度单元中的上行频域调度单元3来传输上行控制信道。
具体而言，S210网络设备在第一下行频域控制区域上，向终端设备发送下行控制信道，可以包括：网络设备在第一下行时域调度单元的第一下行频域控制区域上，向终端设备发送下行控制信道；第二配置信息包括至少一个第一上行时域调度单元中每个第一上行频域控制区域分别相对于第一下行时域调度单元的偏移量的信息。当然，***还可以为上行时隙编号，第二配置信息中指示用于传输上行控制信道的上行时隙的编号，本发明实施例对上行时隙的具体指示方式不作限定。
图4示出的示意图中仅在一个上行时隙中传输上行控制信道。本发明实施例的上行控制信道可以在多个上行时隙中传输。此时，第二配置信息可以指示多个上行时隙的编号，或者指示起始的上行时隙的编号及多个上行时隙中其他上行时隙与起始的上行时隙在时域上相对偏移量，或者指示起始的上行时隙的编号及连续的上行时隙的数量，等等，本发明实施例对于多个上行时隙的具体指示方式不作限定。
第一配置信息也相应有不同的指示方式。其中一种指示方式是，如果***对每个上行时隙中的上行频域控制区域分别编号，并且所有上行时隙均采用相同编号的上行频域控制区域来传输上行控制信道，则第一配置信息仍然仅指示上行频域控制区域的编号即可，该编号作用于所有上行时隙的上行控制信道。
概括而言，第二配置信息用于指示N个第一上行时域调度单元，第一配置信息用于指示N个第一上行频域控制区域，其中，每个第一上行频域控制区域位于一个第一上行时域调度单元内，任意两个第一上行频域控制区域位于不同的第一上行时域调度单元，任意两个第一上行频域控制区域在对应的第一上行时域调度单元内的频域位置是相同的。
第一配置信息的另外一种指示方式是，如果***对所有上行时隙中的所有上行频域控制区域顺序编号，因为多个上行频域控制区域中不会有重复的 编号，则第一配置信息指示出所有的上行频域控制区域的编号即可。第一配置信息的又一种指示方式是，如果***对每个上行时隙中的上行频域控制区域分别编号，并且存在两个上行时隙采用不同编号的上行频域控制区域来传输上行控制信道，则第一配置信息分别指示每一个上行时隙中的上行频域控制区域的编号。本发明实施例，对第一配置信息的具体指示方式不作限定。
图5示出了本发明另一个实施例的传输上行控制信道的方法的示意图。在该具体的场景中，如图5所示，***中多个(例如2个)下行时域调度单元(例如下行时隙1和下行时隙2)对应一个上行时域调度单元(例如上行时隙)。在该情况下，***对所有下行时隙中的所有下行频域控制区域顺序编号，多个下行时隙中的所有下行频域控制区域中不会有重复的编号，共K个。上行时域调度单元中每个上行频域控制区域中包括K个上行频域调度单元。
如图5所示，假设下行时隙1中包括1个下行频域控制区域，下行频域控制区域1；下行时隙2中包括3个下行频域控制区域，下行频域控制区域2、下行频域控制区域3和下行频域控制区域4。网络设备在下行时隙2的3个下行频域控制区域中的下行频域控制区域3向终端设备发送下行控制信道。上行时域调度单元(上行时隙)中包括3个上行频域控制区域，上行频域控制区域1、上行频域控制区域2和上行频域控制区域3。每个上行频域控制区域中包括4个上行频域调度单元，与下行时隙1中的1个下行频域控制区域和下行时隙2中的3个下行频域控制区域对应。
网络设备在下行频域控制区域3上，向终端设备发送的下行控制信道中包括第一配置信息，第一配置信息包括终端设备的上行控制信道所使用的上行频域控制区域的信息，例如在图5的例子中为上行频域控制区域2。该终端设备的上行控制信道所使用的上行频域调度单元由映射关系f(s)确定，这里f(s)＝s，即使用上行频域控制区域2的4个上行频域调度单元中的上行频域调度单元3来传输上行控制信道。
图6示出了本发明另一个实施例的传输上行控制信道的方法的示意图。在该具体的场景中，如图6所示，***中多个(例如2个)下行时域调度单元(例如下行时隙1和下行时隙2)对应一个上行时域调度单元(例如上行时隙)。在该情况下，***对每个下行时隙中的下行频域控制区域分别编号，多个下行时隙中的下行频域控制区域中共K个。上行时域调度单元中每个上 行频域控制区域中包括K个上行频域调度单元。
如图6所示，假设下行时隙1中包括1个下行频域控制区域，下行频域控制区域1；下行时隙2中包括3个下行频域控制区域，下行频域控制区域1、下行频域控制区域2和下行频域控制区域3。网络设备在下行时隙2的3个下行频域控制区域中的下行频域控制区域2向终端设备发送下行控制信道。上行时域调度单元(上行时隙)中包括3个上行频域控制区域，上行频域控制区域1、上行频域控制区域2和上行频域控制区域3。每个上行频域控制区域中包括4个上行频域调度单元，与下行时隙1中的1个下行频域控制区域和下行时隙2中的3个下行频域控制区域对应。
在这种情况下，方法200还可以包括：网络设备向终端设备发送第三配置信息，第三配置信息用于指示用于确定至少一个第一上行频域控制区域中每个第一上行频域控制区域的第一上行频域调度单元的起始频域位置的信息。
具体而言，一个具体的例子中，网络设备可以通过高层信令与终端设备交互各个下行时隙中下行频域控制区域的情况(至少包括下行频域控制区域的个数)。第三配置信息可以包括下行时隙的编号，这样终端设备根据下行时隙的编号，以及每个时隙中下行频域控制区域的个数，就可以得知上行时隙中每个上行频域控制区域中用于传输上行控制信道的上行频域调度单元的起始位置。
另一个具体的例子中，第三配置信息可以包括被选中的下行时隙之前的所有下行时隙的下行频域控制区域的个数f(p)，这样终端设备根据该个数，就可以得知上行时隙中每个上行频域控制区域中用于传输上行控制信道的上行频域调度单元的起始位置。终端设备的上行控制信道在第一配置信息指示的第一上行频率控制区域内的具***置由f(p)和f(s)联合确定，即通过f(p)确定与其他下行时隙映射的上行控制信道占据的上行频域调度单元的个数，从而确定与终端设备的下行控制信道所在的下行时隙映射的上行控制信道占据的上行频域调度单元的起点，然后再在这个起点基础上用f(n)确定具***置。
网络设备在下行时隙2的下行频域控制区域2(s＝2)上，向终端设备发送的下行控制信道中包括第一配置信息，第一配置信息包括终端设备的上行控制信道所使用的上行频域控制区域的信息，例如在图6的例子中为上行频 域控制区域2。网络设备可以向终端设备发送第三配置信息，第三配置信息包括下行时隙2之前的下行时隙1中的下行频域控制区域的个数(1个)，即f(p)＝1。该终端设备的上行控制信道所使用的上行频域调度单元由f(p)+f(s)确定，这里f(s)＝s，f(p)+f(s)＝3，即使用上行频域控制区域2的4个上行频域调度单元中的上行频域调度单元3来传输上行控制信道。
5G***的覆盖频段也许会很宽(尤其在高频段)，这使得终端设备在整个频段上去检测控制信道需要耗费大量的终端设备资源，因此终端设备可能仅支持一定的频域范围(或者称频域带宽)。或者，终端设备在下行方向覆盖所有覆盖频段，在上行方向仅覆盖一定的频域范围。在这种情况下，方法200还可以包括：网络设备向终端设备发送第四配置信息，第四配置信息用于指示终端设备能够使用的频域范围，至少一个第一上行频域控制区域为频域范围内的上行频域控制区域。
换而言之，网络设备可以向终端设备发送第四配置信息，在***带宽内指示出一个频域范围W。再由第一配置信息指示终端设备的上行控制信道在W内的上行频域控制区域中的第一上行频域控制区域发送。该频域范围W可以包含连续的频域资源，也可以包含不连续的频域资源，本发明实施例对此不做限定。
图7示出了本发明另一个实施例的传输上行控制信道的方法的示意图。在该具体的场景中，如图7所示，终端设备的上行控制信道限制在一个频域范围W(子带)内，以一个下行时隙对应一个固定的上行时隙的情况为例，网络设备先通过第四配置信息指示终端设备的上行控制信道可能分布的频域范围W，然后通过第一配置信息指示终端设备的上行控制信道安排在W内的2个下行频域控制区域中的下行频域控制区域2发送，终端设备的上行控制信道在下行频域控制区域2中的具***置由终端设备的下行控制信道所在的上行频域控制区域(上行频域控制区域3)确定，即在第3个上行频域调度单元3。
可选地，在本发明实施例中，网络设备可以通过高层信令(例如RRC信令)、下行控制信道、广播信道或***信息块(System Information Block，SIB)向终端设备发送第三配置信息和/或第四配置信息，本发明实施例对此不作限定。
