Description

一种资源指示方法、资源获取方法及相关装置
本申请要求于2017年02月04日提交中国专利局、申请号为201710064600.8、申请名称为“一种资源指示方法、资源获取方法及相关装置”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
本申请涉及通信领域，尤其涉及一种资源指示方法、资源获取方法及相关装置。
背景技术
在无线通信系统如长期演进(Long Term Evolution，LTE)系统或先进的长期演进(Long Term Evolution Advanced，LTE-A)系统中，网络设备通过物理下行控制信道(Physical Downlink Control CHannel，PDCCH)发送下行控制信令并在物理下行共享信道(Physical Downlink Share CHannel，PDSCH)发送下行数据，终端设备在接收下行数据后，在物理上行控制信道(Physical Uplink Control CHannel，PUCCH)上反馈混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)确定/否定应答(Acknowledgement/Negative Acknowledgement，ACK/NACK)的信息。
在致力于支持更高系统性能的5G通信系统中，如果沿用传统的LTE或LTE-A系统中的PUCCH资源配置方法，则网络设备会通过高层信令在PUCCH资源上为每个下行时隙均预留足够的HARQ ACK/NACK反馈资源。一旦网络设备下行数据调度的终端设备占用的资源明显少于网络设备预先调度配置的PUCCH资源的情况时，有限的5G资源会因为预留的资源无法灵活配置而导致产生较多的资源碎片，从而造成大量资源浪费而无法正常配置给终端设备使用。

具体实施方式
本发明实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、终端设备(User Device)、或用户装备(User Equipment)。
本发明实施例所涉及的网络设备(例如，接入点),可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。网络设备可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。网络设备还可协调对空中接口的属性管理。例如，网络设备可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本申请并不限定。
图1所示的无线通信系统架构示意图中，网络设备，例如基站,无线局域网接入点等各种传输接收点(transmission reception point，TRP)，为终端设备提供授权频谱下的接入服务或非授权频谱下的接入服务。所述终端设备和所述网络设备在上行链路和下行链路上按照协议层传输各种数据，例如控制信令或业务数据。其中，控制信令主要在控制信道上传输，业务数据主要在业务信道上传输。这些协议层包括物理层、媒体接入控制(media access control,MAC)层以及无线资源控制(radio resource control,RRC)层等。无论是在哪一层传输的数据，最终承载在物理层上通过至少一个物理天线在无线空间中传输。
网络设备通过高层信令半静态地为终端设备配置上行控制信道资源，并通过发送的下行控制信令隐性的指示终端设备在上行控制信道资源池中使用的上行控制信道资源，以用于终端设备反馈HARQ ACK/NACK的信息。隐形指示的资源是网络设备按照在每一个被调度的时隙上可被调度的最大数量的终端设备预留的足够的上行控制信道资源，这确保在该时隙上每一个被调度的终端设备都能有足够的资源可以反馈HARQ ACK/NACK信息。然而，因为预留资源一旦被配置便不可再灵活调度，当网络设备下行数据调度的终端设备数量明显少于网络设备预先调度配置的上行控制信道资源时，预留的资源此会产生较多的资源碎片，这种问题在资源有限的5G系统下尤为突出。
可选的，上行控制信道资源包括物理上行控制信道PUCCH资源。以下的步骤和装置的描述中都基于PUCCH资源，但是本发明的方法和装置并不局限于PUCCH资源。
鉴于上述技术问题，本发明实施例一方面提供了一种资源的指示和获取方法，如图2所示，所述方法包括以下步骤：
201、网络设备生成下行控制信令，其中，所述下行控制信令包含指示信息和资源分配信息，所述资源分配信息用于对上行控制信道资源进行显性指示或隐性指示，所述指示信息用于表示所述资源分配信息的指示方式为所述显性指示或所述隐性指示。
根据本发明的实施例，上行控制信道资源至少包括时域、频域或码域资源中的一种。
传统方法中，上行控制信道的资源都是通过下行控制信令隐性的指示终端设备在PUCCH资源池中使用的PUCCH资源，这些资源因为是预留资源，一旦配置完成便不能灵活调度。在本发明实施例的方法中，网络侧将PUCCH资源的分配指示为显性指示或隐性指示的方式。其中，显性指示表示通过信令直接指示终端设备对应的资源；隐性指示表示通过资源信息与所述终端设备建立关联，通过该关联指示所述终端设备对应的资源。具体而言，显性指示的PUCCH资源是通过下行控制信令中的指示信息来直接指示终端设备进行反馈HARQ ACK/NACK的PUCCH资源；隐性指示的PUCCH资源是通过物理下行控制信道PDCCH的资源信息与终端设备建立关联，通过该关联指示终端设备进行反馈HARQ ACK/NACK的PUCCH资源。
下行控制信令用于分配下行数据传输占用的资源，以及分配上行应答信息反馈占用的资源。下行控制信令中的信息包括物理下行控制信道PDCCH的资源信息，还包括下行数据所占的物理资源块(Physical Resource Block，PRB)的索引信息。
可选的，隐性指示为PUCCH资源以PDCCH中占用的控制信道单元(Control Channel Element，CCE)的索引的最小值作为入口参数的函数获得。例如，公式1为PUCCH资源获取的一种隐性指示的示例：
Figure PCTCN2017114635-appb-000001
其中，
Figure PCTCN2017114635-appb-000002
表示PUCCH占用的资源；nCCE表示PDCCH中占用的控制信道单元CCE的索引的最小值；
Figure PCTCN2017114635-appb-000003
为网络设备为终端设备通过高层信令配置的参数。
图3为一PUCCH资源示意图。传统方法中，图3为一隐性指示的PUCCH资源的 整体区域，按照本发明实施例的方法，将隐性指示的PUCCH资源通过预定义或高层信令半静态地划分为几个子资源块。例如，在图3中将隐性指示的PUCCH资源R2划分为A、B、C、D 4个子资源块。当网络设备下行数据调度的终端设备数量明显少于网络设备预先调度配置的PUCCH资源，子资源块D被配置为显性指示的PUCCH资源R1，子资源块A、B、C仍被用作隐性指示的PUCCH资源。随着网络设备下行数据调度的终端设备数量的变化，PUCCH资源的指示方式可以动态调整，这样的指示方式可以更灵活地使用PUCCH资源，进一步地提高资源的利用率。
可选的，资源分配信息由所述下行控制信令中的第二信息位或第三信息位承载。
可选的，在生成的下行控制信令中，如果指示信息表示资源分配信息的指示方式为显性指示，则资源分配信息被配置为在下行控制信令的第二信息位指示终端设备对应的显性指示的资源索引。可选的，下行控制信令的第二信息位配置为4bit，则该次网络设备调度的终端设备数量最多为24＝16，这些终端设备对应的资源索引信息为[0，15]。即网络设备在本次下行调度时，通过4bit的资源分配信息与显性指示的PUCCH资源索引信息[0，15]一一对应(如表1中所示)指示属于该终端设备的具体资源位置。
表1 比特信息与资源索引对应表
资源索引 对应比特信息 资源索引 对应比特信息
0 0000 8 1000
1 0001 9 1001
2 0010 10 1010
3 0011 11 1011
4 0100 12 1100
5 0101 13 1101
6 0110 14 1110
7 0111 15 1111
可选的，在生成的下行控制信令中，如果指示信息表示资源分配信息的指示方式为隐性指示，则资源分配信息被配置为在下行控制信令的第三信息位指示终端设备对应的隐性指示的资源索引。可选的，下行控制信令的第三信息位配置为2bit，网络设备将下行控制信令所对应的CCE的索引最小值与终端设备所对应的隐性指示的PUCCH资源子块的索引建立关联。
202、网络设备发送下行控制信令。
网络设备将步骤201生成的包含指示信息和资源分配信息的下行控制信令发送给终端设备。
可选的，所述指示信息由所述下行控制信令中的第一信息位承载，或者，所述第一指示信息由用于加扰所述下行控制信令的扰码承载。
所属技术领域的技术人员都知道，下行控制信令中的指示信息包含的比特信息越多，终端设备的资源位置信息就会越详细，同时不可避免地，也会产生大量的信令开销。可选的，下行控制信令中的指示信息配置为1bit。即，网络设备对终端设备进行下行数据调度时，配置1bit的指示信息来表示所述资源分配信息的指示方式为所述显性指示或所述隐性指示。因为指示信息只被配置为1bit，这极大地减少了信令的开销，从而最大程度地提高了资源的利用率。
可选的，下行控制信令中的第一信息位可以隐性指示第二信息位和第三信息位的信息。如果在下行传输的单级控制信道中，下行控制信令中的第一信息位、第二信息位和第三信息位分别是独立的，第二信息位和第三信息位的长度为固定长度。可选的，第二信息位和第三信息位可以进行复用以提高资源的利用率，即网络设备可以配置第二信息位和第三信息位为同一个信息位。如果在下行传输的两级控制信道中，下行控制信令中的第一信息位可以放在第一级控制信道中也可以放在第二级控制信道中，而第二信息位和第三信息位只能放在第二级控制信道中。如果在下行传输的两级控制信道中，第一信息位放在第一级控制信道中，则第二信息位和第三信息位可以是变长的；如果第一信息位放在第二级控制信道中，则第二信息位和第三信息位只能是定长的。其中，单级控制信道是指下行链路的控制信道包括一个控制区域，两级控制信道是指下行链路的控制信道包括两个控制区域。
图4示出了一种下行传输的两级控制信道的结构框图。其中，DL(Downlink)指下行链路区域；GP(Guard Period，保护间隔)是指下行链路与上行链路之间的保护间隔；UL(uplink)是指上行区域；401为终端设备1数据区域，402为终端设备2数据区域，终端设备1和2表示不同的终端设备；403为第一级控制信道，用于承载指示包括调度时频资源的索引信息；404为第二级控制信道，用于承载指示传输时间取值的信息。第一级控制信道403位于整个下行信道的控制区域(即图3中DL区域内的虚线左侧区域)，第二级控制信道404可以在下行信道的控制区域内也可以在数据区域内。其中，控制区域是指仅承载网络设备调度终端设备的控制信息的下行链路区域，数据区域是指仅用于网络设备传输给终端设备的数据的下行链路区域。对于不同的终端设备而言，第二级控制信道404的资源起始位置可以不同。
两级控制信道的结构包括两级下行控制信令。第一级下行控制信令在第一级控制信道403中进行发送，其包括用户ID，资源分配信息以及第二级下行控制信令的容量等信息；第二级下行控制信令在第二级控制信道404中进行发送，其包括发送监听参考信号的请求信息以及资源分配信息等信息。其中，第一级下行控制信令包括的资源分配信息用于指示第二级下行控制信令在第二级控制信道404中的时频资源位置。第一级控制信道403的时频资源的大小不等同于第二级控制信道404的时频资源的大小，但是第二级控制信道404的时频资源要依赖于第一级控制信道403中第一级下行控制信令的调度指示信息。
203、终端设备接收下行控制信令。
终端设备接收包含指示信息和资源分配信息的下行控制信令后，便获得了息用于 对上行控制信道资源进行显性指示或隐性指示的资源分配信息和用于表示所述资源分配信息的指示方式为所述显性指示或所述隐性指示的指示信息。
可选的，终端设备接收所述下行控制信令中的第一信息位承载的所述指示消息，或者所述终端设备解扰所述下行控制信令扰码承载的所述指示信息。可选的，终端设备接收所述下行控制信令中的第二信息位或第三信息位承载的所述资源分配信息。
204、终端设备根据所述指示信息获取所述资源分配信息的指示方式为显性指示或隐性指示，以及根据所述资源分配信息获取所述显性指示或所述隐性指示的上行控制信道资源。
可选的，如果终端设备接收到的指示信息为第一预设值，则终端设备获取该次数据调度对应的资源是显性指示的PUCCH资源；如果指示信息为第二预设值，则终端设备获取该次数据调度对应的资源是隐性指示的PUCCH资源。其中，第一预设值与第二预设值不同。例如，可以将第一预设值配置为01，第二预设值配置为00等等。
可选的，如果接收到的指示信息表示资源分配信息的指示方式为显性指示，则终端设备根据接收到的下行控制信令的第二信息位获取终端设备对应的显性指示的资源索引。例如，下行控制信令中的第二信息位配置为4bit，即本次网络设备调度的终端设备数量最多为24＝16，对应的资源索引为[0，15]。终端设备根据与资源索引[0，15]一一对应的表1获取显性指示的PUCCH资源位置。
可选的，如果接收到的指示信息表示资源分配信息的指示方式为隐性指示，则终端设备根据接收到的下行控制信令的第三信息位获取终端设备对应的隐性指示的资源索引。可选的，终端设备根据接收的下行控制信令中获取的物理资源的CCE索引的最小值与终端设备对应的隐性指示的PUCCH资源子块的索引建立的关联，通过计算获得在该资源子块上对应的资源位置。
本发明的实施例中，通过预定义或高层信令半静态的方式在下行控制信令中为终端设备配置显性指示和隐性指示的PUCCH资源的信令，根据数据调度的终端设备数量动态配置资源指示，使上行控制信道资源可以合理规划和灵活配置，在资源比较有限的5G通信系统中，能够最大限度的利用资源，减小资源的碎片化，达到比较好的技术效果。
本发明实施例另一方面还提供了一种网络设备，如图5所示，其中，网络设备50包括：处理单元501，收发单元502。
处理单元501，用于生成下行控制信令，其中，所述下行控制信令包含指示信息和资源分配信息，所述资源分配信息用于对上行控制信道资源进行显性指示或隐性指示，所述指示信息用于表示所述资源分配信息的指示方式为所述显性指示或隐性指示。
根据本发明实施例，上行控制信道资源至少包括时域、频域或码域资源中的一种。
传统方法中，上行控制信道的资源都是通过下行控制信令隐性的指示终端设备在PUCCH资源池中使用的PUCCH资源，这些资源因为是预留资源，一旦配置完成便不能灵活调度。在本发明实施例的方法中，网络侧将PUCCH资源的分配指示为显性指示或隐性指示的方式。其中，显性指示表示通过信令直接指示终端设备对应的资源；隐性指示表示通过资源信息与所述终端设备建立关联，通过该关联指示所述终端设备对应的资源。具体而言，显性指示的PUCCH资源是通过下行控制信令中的指示信息 来直接指示终端设备进行反馈HARQ ACK/NACK的PUCCH资源；隐性指示的PUCCH资源是通过物理下行控制信道PDCCH的资源信息与终端设备建立关联，通过该关联指示终端设备进行反馈HARQ ACK/NACK的PUCCH资源。
下行控制信令用于分配下行数据传输占用的资源，以及分配上行应答信息反馈占用的资源。下行控制信令中的信息包括物理下行控制信道PDCCH的资源信息，还包括下行数据所占的物理资源块(Physical Resource Block，PRB)的索引信息。
可选的，隐性指示为PUCCH资源以PDCCH中占用的控制信道单元CCE的索引的最小值作为入口参数的函数获得。例如，公式1为PUCCH资源获取的一种隐性指示的示例。
可选的，处理单元501用于生成由所述下行控制信令中的第一信息位承载的所述指示信息，或者，处理单元501用于生成由用于加扰所述下行控制信令的扰码承载的所述指示信息。
所属技术领域的技术人员都知道，下行控制信令中的指示信息包含的比特信息越多，终端设备的资源位置信息就会越详细，同时不可避免地，也会产生大量的信令开销。可选的，处理单元501生成1bit的下行控制信令中的指示信息。因为指示信息只有1bit，这极大地减少了信令的开销，从而最大程度地提高了资源的利用率。
可选的，处理单元501用于生成由所述下行控制信令中的第二信息位或第三信息位承载的所述资源分配信息。
可选的，在处理单元501生成的下行控制信令中，如果指示信息表示资源分配信息的指示方式为显性指示，则资源分配信息被配置为在下行控制信令的第二信息位指示终端设备对应的显性指示的资源索引。可选的，下行控制信令的第二信息位配置为4bit，则该次网络设备调度的终端设备数量最多为24＝16，这些终端设备对应的资源索引信息为[0，15]。即网络设备在本次下行调度时，通过4bit的资源分配信息与显性指示的PUCCH资源索引信息[0，15]一一对应(如表1中所示)指示属于该终端设备的具体资源位置。
可选的，在处理单元501生成的下行控制信令中，如果指示信息表示资源分配信息的指示方式为隐性指示，则资源分配信息被配置为在下行控制信令的第三信息位指示终端设备对应的隐性指示的资源索引。可选的，下行控制信令的第三信息位配置为2bit，网络设备将下行控制信令所对应的CCE的索引最小值与终端设备所对应的隐性指示的PUCCH资源子块的索引建立关联。
收发单元502，用于发送下行控制信令。
可选的，下行控制信令中的第一信息位可以隐性指示第二信息位和第三信息位的信息。如果在下行传输的单级控制信道中，下行控制信令中的第一信息位、第二信息位和第三信息位分别是独立的，第二信息位和第三信息位的长度为固定长度。可选的，第二信息位和第三信息位可以进行复用以提高资源的利用率，即网络设备可以配置第二信息位和第三信息位为同一个信息位。如果在下行传输的两级控制信道中，下行控制信令中的第一信息位可以放在第一级控制信道中也可以放在第二级控制信道中，而第二信息位和第三信息位只能放在第二级控制信道中。如果在下行传输的两级控制信道中，第一信息位放在第一级控制信道中，则第二信息位和第三信息位可以是变长的； 如果第一信息位放在第二级控制信道中，则第二信息位和第三信息位只能是定长的。其中，单级控制信道是指下行链路的控制信道包括一个控制区域，两级控制信道是指下行链路的控制信道包括两个控制区域。
需要说明的是，本发明实施例提供的网络设备50可以执行前述方法实施例中网络设备的各种动作。收发单元502用于执行前述方法实施例中网络设备的发送动作和接收动作，处理单元501用于执行前述方法实施例的获取，确定等处理动作。在物理实现中，收发单元502可以为收发器，处理单元501可以为处理器，如图6所示，60为网络设备，其包括处理器601和收发器602。它们通过各种电子线路接口(例如总线)连接在一起。
本发明的实施例中，通过预定义或高层信令半静态的方式在下行控制信令中为终端设备配置显性指示和隐性指示的PUCCH资源的信令，根据数据调度的终端设备数量动态配置资源指示，使上行控制信道资源可以合理规划和灵活配置，在资源比较有限的5G通信系统中，能够最大限度的利用资源，减小资源的碎片化，达到比较好的技术效果。
本发明实施例另一方面还提供了一种终端设备，如图7所示，其中，终端设备70包括：收发单元701，处理单元702。
收发单元701，用于接收下行控制信令，其中，所述下行控制信令包含指示信息和资源分配信息。
收发单元701接收包含指示信息和资源分配信息的下行控制信令后，便获得了息用于对上行控制信道资源进行显性指示或隐性指示的资源分配信息和用于表示所述资源分配信息的指示方式为所述显性指示或所述隐性指示的指示信息。
可选的，收发单元701接收所述下行控制信令中的第一信息位承载的所述指示消息，或者所述终端设备解扰所述下行控制信令扰码承载的所述指示信息。可选的，终端设备接收所述下行控制信令中的第二信息位或第三信息位承载的所述资源分配信息。
处理单元702，用于根据所述指示信息获取所述资源分配信息的指示方式为显性指示或隐性指示，以及根据所述资源分配信息获取所述显性指示或所述隐性指示的上行控制信道资源。
可选的，如果收发单元701接收到的指示信息为第一预设值，则处理单元702获取该次数据调度对应的资源是显性指示的PUCCH资源；如果指示信息为第二预设值，则处理单元702获取该次数据调度对应的资源是隐性指示的PUCCH资源。其中，第一预设值与第二预设值不同。例如，可以将第一预设值配置为01，第二预设值配置为00等等。
可选的，如果收发单元701接收到的指示信息表示资源分配信息的指示方式为显性指示，则处理单元702根据接收到的下行控制信令的第二信息位获取终端设备对应的显性指示的资源索引。例如，下行控制信令中的第二信息位配置为4bit，即本次网络设备调度的终端设备数量最多为24＝16，对应的资源索引为[0，15]。则处理单元702根据与资源索引[0，15]一一对应的表1获取显性指示的PUCCH资源位置。
可选的，如果收发单元701接收到的指示信息表示资源分配信息的指示方式为隐性指示，则处理单元702根据接收到的下行控制信令的第三信息位获取终端设备对应 的隐性指示的资源索引。可选的，处理单元702根据接收的下行控制信令中获取的物理资源的CCE索引最小值与终端设备对应的隐性指示的PUCCH资源子块的索引建立的关联，获得在该资源子块上对应的资源位置。
需要说明的是，本发明实施例提供的终端设备70可以执行前述方法实施例中终端设备的各种动作。收发单元701用于执行前述方法实施例中终端设备的接收和发送动作，处理单元702用于执行前述方法实施例终端设备的获取，确定等处理动作。在物理实现中，收发单元701可以为收发器，处理单元702可以为处理器，如图8所示，80为终端设备，其包括处理器802和收发器801。它们通过各种电子线路接口(例如总线)连接在一起。
本发明的实施例中，通过预定义或高层信令半静态的方式在下行控制信令中为终端设备配置显性指示和隐性指示的PUCCH资源的信令，根据数据调度的终端设备数量动态配置资源指示，使上行控制信道资源可以合理规划和灵活配置，在资源比较有限的5G通信系统中，能够最大限度的利用资源，减小资源的碎片化，达到比较好的技术效果。
本发明实施例另一方面还提供了一种资源的指示和获取方法，如图9所示，所述方法包括以下步骤：
901、网络设备配置上行控制信道资源索引，其中，所述上行控制信道资源索引包含在目标时隙上对应的上行控制信道资源索引的公共偏移值与UE特定偏移值。
根据本发明的实施例，上行控制信道资源至少包括时域、频域或码域资源中的一种。
对于某一个时隙而言，由于其上的PUCCH资源可能已经有部分资源被占用的情况(例如，在当前时隙之前的时隙调度数据时，有一部分PUCCH资源被网络设备分配给了终端设备使用)，并且各个时隙上PUCCH资源被占用的情况不同，因此，在数据调度时，网络设备为终端设备配置了PUCCH资源索引。其中，PUCCH资源索引包含在目标时隙上对应的PUCCH资源索引的公共偏移值(Common Offset)与UE特定偏移值。不同的目标时隙被配置了其对应的PUCCH资源索引的公共偏移值。可选的，网络设备可以在下行公共搜索空间(Common Search Space，CSS)上发送的公共调度信令配置不同HARQ ACK/NACK timing信息对应的PUCCH资源索引的公共偏移值。其中，timing信息是指终端设备在接收到下行数据后到对应时刻的时隙上反馈HARQ ACK/NACK信息的固定时刻。当网络设备调度第n个时隙进行数据传输，而终端设备会在当前下行数据调度的第n+K个时隙上反馈HARQ ACK/NACK信息时，则K就是HARQ ACK/NACK的timing值。其中，n和K为大于0的整数。终端设备收到timing信息便可以获知反馈HARQ ACK/NACK的时隙信息。
可选的，网络设备基于所述目标时隙上的资源占用情况配置所述公共偏移值。可选的，PUCCH资源索引的公共偏移值对应PUCCH资源索引的上限值或者下限值。PUCCH资源索引的公共偏移值由网络设备通过预定义或高层信令半静态配置的方式配置。
当配置为PUCCH资源索引的上限值时，目标时隙的终端设备所对应的PUCCH资源索引为：
资源索引＝公共偏移值-UE特定偏移值         (公式2)
当配置为PUCCH资源索引的下限值时，目标时隙的终端设备所对应的PUCCH资源索引为：
资源索引＝公共偏移值+UE特定偏移值                (公式3)
网络设备通过预定义或高层信令半静态配置的方式配置下行控制信令，用以指示PUCCH资源索引的公共偏移值为对应的PUCCH资源索引的上限值还是下限值。当下行控制信令指示为上限值时，终端设备使用公式2获取所属的资源索引；当下行控制信令指示为下限值时，终端设备使用公式3获取所属的资源索引。
当下行数据调度的终端设备数量比较多时，为了提高资源的利用率，对应的PUCCH资源索引的公共偏移值可以配置为PUCCH资源索引的粗粒度的指示。即，如果一段周期内网络设备进行下行数据调度时终端设备的数量比较多，就可以半静态配置公共偏移值的粒度大一些；如果一段周期内网络设备进行下行数据调度时终端设备的数量比较少，则可以半静态配置公共偏移值的粒度小一些。可选的，网络设备以预定值为粒度为所述终端设备配置PUCCH资源索引的公共偏移值。网络设备通过预定于或高层信令半静态配置的方式配置该预定值。例如，当网络设备为任一个时隙配置PUCCH资源索引的公共偏移值时，可以配置为[0，i，2i，3i]，其中i表示PUCCH资源索引公共偏移值的粒度，i是正整数。网络设备根据每个时隙的PUCCH的资源占用情况分别为每个时隙配置对应的PUCCH资源索引的公共偏移值[0，i，2i，3i]中的其中一个数值。对应的PUCCH资源索引的公共偏移值的粒度i由网络设备通过预定义或高层信令半静态配置的方式配置。
902、网络设备发送承载所述公共偏移值和所述UE特定偏移值的信令。
可选的，网络设备在进行下行数据调度时，会将已经配置好的每个时隙对应的PUCCH资源索引的公共偏移值通过广播信令通知终端设备。广播信令所占用的频域资源以及子载波间隔由网络设备通过预定义或高层信令半静态配置的方式配置。可选的，网络设备在下行公共搜索空间CSS上进行广播通知。
在广播完成每个时隙对应的PUCCH资源索引的公共偏移值后，网络设备发送下行控制信令。下行控制信令中承载着目标时隙对应的PUCCH资源索引的UE特定偏移值。其中，PUCCH资源索引的UE特定偏移值是针对每个时隙中的每个终端设备在PUCCH资源索引的公共偏移值上的一特定的偏移值。每个时隙上的终端设备对应的PUCCH资源索引的UE特定偏移值都不同并且可以动态配置，以使每个终端设备可以分配到不同的PUCCH资源以用于反馈HARQ ACK/NACK信息。下行控制信令中包含着指示信息，用以纤细动态地指示终端设备对应的PUCCH资源索引的UE特定偏移值。903、终端设备接收目标时隙对应的上行控制信道资源索引的公共偏移值和UE特定偏移值。
可选的，终端设备在初始接入后，开始在下行公共搜索空间进行检测，当在广播信道检测到网络设备广播的包含下行数据调度所对应的PUCCH资源索引的公共偏移值的广播信令后，终端设备在广播信道中接收该广播信令从而获得对应的PUCCH资源索引的公共偏移值。
随后，终端设备接收网络设备发送的下行控制信令，其中下行控制信令中承载着 目标时隙对应的PUCCH资源索引的UE特定偏移值。下行控制信令中包含着指示信息，用以纤细动态地指示终端设备对应的PUCCH资源索引的UE特定偏移值。
904、终端设备根据所述公共偏移值和所述UE特定偏移值获取所述终端设备对应的上行控制信道资源索引。
终端设备接收网络设备的下行控制信令时，会在该下行调度信令中检测对应的HARQ ACK/NACK反馈的timing信息(即K)。检测到timing信息，会继续检测下行控制信令，根据下行控制信令中的预定义或高层信令半静态配置的指示，获取所述公共偏移值为对应的上行控制信道资源索引的上限值还是下限值。当下行控制信令指示为上限值时，终端设备使用公式2获取所属的资源索引；当下行控制信令指示为下限值时，终端设备使用公式3获取所属的资源索引。之后，终端设备在timing信息对应的时隙上找到配置给自己的PUCCH资源，然后将该HARQ ACK/NACK信息在该资源上反馈给网络设备。
本发明实施例中，网络设备首先为终端设备配置了不同时隙上HARQ ACK/NACK对应的PUCCH资源索引的公共偏移值和UE特定偏移值，然后通过信令的方式将公共偏移值和UE特定偏移值发送给终端设备，终端设备接收信令，并根据信令指示获取终端设备所属PUCCH资源索引。本发明实施例的方法中，通过广播和指示消息的形式动态通知终端设备所属的PUCCH资源索引，减少了的资源碎片化，提高了资源的利用率。
本发明实施例另一方面还提供了一种网络设备，如图10所示，其中，网络设备100包括：处理单元1001，收发单元1002。
处理单元1001，用于配置上行控制信道资源索引；其中，所述上行控制信道资源索引包含在目标时隙上对应的上行控制信道资源索引的公共偏移值与UE特定的偏移值。
对于某一个时隙而言，由于其上的PUCCH资源可能已经有部分资源被占用的情况(例如，在当前时隙之前的时隙调度数据时，有一部分PUCCH资源被网络设备分配给了终端设备使用)，并且各个时隙上PUCCH资源被占用的情况不同，因此，在数据调度时，处理单元1001为终端设备配置了PUCCH资源索引。其中，PUCCH资源索引包含在目标时隙上对应的PUCCH资源索引的公共偏移值与UE特定偏移值。不同的目标时隙被配置了其对应的PUCCH资源索引的公共偏移值。可选的，处理单元1001可以在下行公共搜索空间CSS上发送的公共调度信令配置不同HARQ ACK/NACK timing信息对应的PUCCH资源索引的公共偏移值。其中，timing信息是指终端设备在接收到下行数据后到对应时刻的时隙上反馈HARQ ACK/NACK信息的固定时刻。当网络设备调度第n个时隙进行数据传输，而终端设备会在当前下行数据调度的第n+K个时隙上反馈HARQ ACK/NACK信息时，则K就是HARQ ACK/NACK的timing值。其中，n和K为大于0的整数。终端设备收到timing信息便可以获知反馈HARQ ACK/NACK的时隙信息。
可选的，处理单元1001基于所述目标时隙上的资源占用情况配置所述公共偏移值。处理单元1001配置PUCCH资源索引的公共偏移值对应PUCCH资源索引的上限值或者下限值。PUCCH资源索引的公共偏移值由处理单元801通过预定义或高层信令半静 态配置的方式配置。
当处理单元1001配置为PUCCH资源索引的上限值时，目标时隙的终端设备所对应的PUCCH资源索引为公式2。
当处理单元1001配置为PUCCH资源索引的下限值时，目标时隙的终端设备所对应的PUCCH资源索引为公式3。
处理单元1001通过预定义或高层信令半静态配置的方式配置下行控制信令，用以指示PUCCH资源索引的公共偏移值为对应的PUCCH资源索引的上限值还是下限值。当下行控制信令指示为上限值时，终端设备使用公式2获取所属的资源索引；当下行控制信令指示为下限值时，终端设备使用公式3获取所属的资源索引。
下行数据调度的终端设备数量比较多时，为了提高资源的利用率，处理单元1001可以配置对应的PUCCH资源索引的公共偏移值为PUCCH资源索引的粗粒度的指示。即，如果一段周期内网络设备进行下行数据调度时终端设备的数量比较多，处理单元1001可以半静态配置公共偏移值的粒度大一些；如果一段周期内网络设备进行下行数据调度时终端设备的数量比较少，处理单元1001可以半静态配置公共偏移值的粒度小一些。可选的，处理单元1001以预定值为粒度为所述终端设备配置PUCCH资源索引的公共偏移值。处理单元1001通过预定于或高层信令半静态配置的方式配置该预定值。例如，当处理单元1001为任一个时隙配置PUCCH资源索引的公共偏移值时，可以配置为[0，i，2i，3i]，其中i表示PUCCH资源索引公共偏移值的粒度，i是正整数。处理单元1001根据每个时隙的PUCCH的资源占用情况分别为每个时隙配置对应的PUCCH资源索引的公共偏移值[0，i，2i，3i]中的其中一个数值。对应的PUCCH资源索引的公共偏移值的粒度i由处理单元1001通过预定义或高层信令半静态配置的方式配置。
收发单元1002，用于发送承载所述公共偏移值和所述UE特定偏移值的信令。
可选的，网络设备在进行下行数据调度时，收发单元1002会将处理单元1001已经配置好的每个时隙对应的PUCCH资源索引的公共偏移值通过广播信令通知终端设备。广播信令所占用的频域资源以及子载波间隔由处理单元1001通过预定义或高层信令半静态配置的方式配置。可选的，收发单元1002在下行公共搜索空间CSS上进行广播通知。
在广播完成每个时隙对应的PUCCH资源索引的公共偏移值后，收发单元1002继续发送下行控制信令。下行控制信令中承载着目标时隙对应的PUCCH资源索引的UE特定偏移值。其中，PUCCH资源索引的UE特定偏移值是针对每个时隙中的每个终端设备在PUCCH资源索引的公共偏移值上的一特定的偏移值。每个时隙上的终端设备对应的PUCCH资源索引的UE特定偏移值都不同并且可以动态配置，以使每个终端设备可以分配到不同的PUCCH资源以用于反馈HARQ ACK/NACK信息。
下行控制信令中包含着指示信息，可选的，处理单元1001通过指示信息纤细动态地指示终端设备对应的PUCCH资源索引的UE特定偏移值。
需要说明的是，本发明实施例提供的网络设备100可以执行前述方法实施例中网络设备的各种动作。收发单元1002用于执行前述方法实施例中网络设备的发送动作和接收动作，处理单元1001用于执行前述方法实施例的获取，确定等处理动作。在物理 实现中，收发单元1002可以为收发器，处理单元1001可以为处理器，如图11所示，网络设备110包括处理器1101和收发器1102，它们通过各种电子线路接口(例如总线)连接在一起。
本发明实施例中，处理单元首先在公共搜索空间上为终端设备配置了不同时隙上HARQ ACK/NACK对应的PUCCH资源索引的公共偏移值，收发单元通过广播信息的方式通知给每一个终端设备，处理单元在下行控制信令中指示终端设备所属PUCCH资源索引。本发明实施例的网络设备中，通过广播和指示消息的形式动态通知终端设备所属的PUCCH资源索引，减少了的资源碎片化，提高了资源的利用率。
本发明实施例另一方面还提供了一种终端设备，如图12所示，其中，终端设备120包括：收发单元1201，处理单元1202。
收发单元1201，用于接收目标时隙对应的上行控制信道资源索引的公共偏移值和UE特定偏移值。
可选的，终端设备在初始接入后，收发单元1201开始在下行公共搜索空间的广播信道进行检测，当在广播信道检测到网络设备广播的包含下行数据调度所对应的PUCCH资源索引的公共偏移值的广播信令后，收发单元1201在广播信道中接收该广播信令从而获得对应的PUCCH资源索引的公共偏移值。
接下来，收发单元1201接收网络设备发送的下行控制信令，其中下行控制信令中承载着目标时隙对应的PUCCH资源索引的UE特定偏移值。其中，PUCCH资源索引的UE特定偏移值是针对每个时隙中的每个终端设备在PUCCH资源索引的公共偏移值上的一特定的偏移值。每个时隙上的终端设备对应的PUCCH资源索引的UE特定偏移值都不同并且可以动态配置，以使每个终端设备可以分配到不同的PUCCH资源以用于反馈HARQ ACK/NACK信息。并且，收发单元1201接收的下行控制信令中还包含着指示信息，用以纤细动态地指示终端设备对应的PUCCH资源索引的UE特定偏移值。
处理单元1202，根据所述公共偏移值和所述UE特定偏移值获取所述终端设备对应的上行控制信道资源索引。
收发单元1201接收网络设备的下行控制信令时，会在该下行调度信令中检测对应的HARQ ACK/NACK反馈的timing信息(即K)。检测到timing信息，收发单元1201会继续检测下行控制信令，处理单元1202根据下行控制信令中的预定义或高层信令半静态配置的指示，获取所述公共偏移值为对应的上行控制信道资源索引的上限值还是下限值。当下行控制信令指示为上限值时，处理单元1202使用公式2获取所属的资源索引；当下行控制信令指示为下限值时，处理单元1202使用公式3获取所属的资源索引。之后，处理单元1202在timing信息对应的时隙上找到配置给终端设备的PUCCH资源，然后收发单元1201将该HARQ ACK/NACK信息在该资源上反馈给网络设备。
需要说明的是，本发明实施例提供的终端设备120可以执行前述方法实施例中终端设备的各种动作。收发单元1201用于执行前述方法实施例中终端设备的接收和发送动作，处理单元1202用于执行前述方法实施例终端设备的获取，确定等处理动作。在物理实现中，收发单元1201可以为收发器，处理单元1202可以为处理器，如图13所示，终端设备130包括处理器1302和收发器1301，它们通过各种电子线路接口(例如总线)连接在一起。
