Description

一种确定控制信道位置方法设备和处理器可读存储介质 技术领域
本发明实施例涉及通信领域，更具体的，涉及一种使用确定控制信道位置的方法，设备和处理器可读存储介质。
背景技术
随着无线通信应用的飞速发展，用户对无线网络的容量和速率需求越来越高。尤其是在无线用户密集的热点地区(大型商场，体育场等)，授权频谱(licensed Spectrum)很难同时为所有用户提供高质量的服务。此外，当前在全球范围内合适的频谱分配趋于紧张，运营商购买授权频段的成本也日渐昂贵。为了降低无线网络的频谱成本，缓解授权频段的业务压力，无线通信网络设计了非授权频谱(Unlicensed Spectrum)上的长期演进(Long Term Evolution,LTE)通信系统。
在未来的第五代(The 5th Generation，5G)通信系统中，基于新无线(New Radio，NR)的通信系统也可以使用非授权频谱资源进行数据通信。
由于非授权频谱是共享的，因此为了减少或避免在非授权频谱上产生冲突，先听后说(Listen before talk，LBT)技术成为使用非授权频谱通信常用的一种共存机制。通过LBT机制获得非授权频段的信道占用权，获得信道占用权的终端设备/网络设备可以在一段时间内发送数据，但发送数据时间长度不能超过最大信道占用时间(Maximum channel occupancy time,MCOT)。
在LTE通信系统中授权频谱辅助接入(Licensed assisted access,LAA)系统是一种基于载波聚合方式使用非授权频谱进行数据通信的长期演进(Long Term Evolution,LTE)系统。LAA系统使用LBT的抢占机制获得非授权频段的信道占用权。通过LAA进行通信过程中，接入网设备先终端设备配置一个或多个非授权频段(或者称为载波，或者小区)做为辅助频段。接入网设备可以为其中的一个或多个非授权频段配置控制信道资源。然后，接入网设备基于LBT监听结果，获得可用的(也称为空闲的，或者竞争到的)频段。接入网设备使用配置的控制信道资源的可用的非授权频段上的控制信道资源向终端设备发送下行控制信息，并使用可用的非授权频段发送下行数据。但是，当配置了控制信道资源的非授权频段不可用时，网络设备与终端设备无法通过其它可用的非授权频带进行通信。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
为了便于理解，下面对本发明实施中涉及的一些概念进行说明：
频带(Band)，在频域上占用一定的宽度。即，一个频带占用一段频谱。比如，一个频带中心频率(或中心频点)是1800兆赫兹，宽度是20兆赫兹。具体的，频带可以可以是频段，或者子带，或者载波，或者小区，或者带宽部分(Bandwidth Part，BWP)。
非授权频带，占用一段非授权频谱。具体的，非授权频带可以是非授权频段，或者非授权载波，或者非授权小区，或者非授权子带，或者非授权BWP。
相应的，可用的非授权频带，也可以称为空闲的或者竞争到的非授权频带。通常，通过检测能量或信号强度的方式，确定一个非授权频带是否可用，具体的，比如一个非授权频带上的接收能量或信号强度小于或等于某个预配置的阈值，则该非授权频带为可用的非授权频带。
辅助频带是以例如载波聚合或双连接或多连接方式进行通信时，用于传输数据和/或控制信令的频带，与主频带对应。具体的，辅助频带可以是辅助载波，或者辅助频段，或者辅助小区，或者辅助子带,或者辅助BWP。
图1给出了本发明所适用的一种通信系统的示例，该通信系统中包括网络设备101，处在网络设备101覆盖范围内并与网络设备101进行通信的终端设备111～112。为简单起见，图1中只给出两个终端设备。但并不意味着只能是两个终端设备。事实上，可以有任意数量个终端设备。应理解，本发明适用于使用非授权频谱通信的无线蜂窝通信网络系统。例如，长期演进(Long Term Evolution,LTE)的授权频谱辅助接入(Licensed assisted access,LAA)系统、增强授权频谱辅助接入(Enhanced Licensed assisted access, eLAA)系统、进一步增强授权频谱辅助接入(Further Enhanced Licensed Assisted Access,FeLAA)系统、5G通信系统以及未来通信系统中使用非授权频谱的通信系统、独立工作在非授权频谱的MulteFire系统等。本发明的实施例以LTE的LAA系统为例，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
应理解，在本发明实施例中，网络设备(例如网络设备101)是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以包括各种形式的无线接入网设备，宏基站，微基站(也称为小站)，中继站，接入点等。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)，也可以是LTE或eLTE中的演进型基站(Evolutional Node B，eNB或e-NodeB)，也可以是下一代移动网络，例如5G(fifth generation)中的基站gNB((next)generation NodeB)，或者是V2X通信中的路边单元(Road Side Unit，RSU)，或者为上述网络设备或者基站内部的芯片或者片上系统(System on Chip，SOC)。为方便描述，本申请中，简称为网络设备或接入网设备，有时也称为基站。
还应理解，在本发明实施例中，终端设备也可称之为用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。为方便描述，本申请中，简称为终端设备或UE。
在本发明实施例中网络设备101和终端设备111～112可以在非授权频谱上进行数据通信，该场景可以是LTE系统中的LAA、eLAA、FeLAA系统、5G通信系统或未来通信系统中使用非授权频谱(例如5150-5350MHz)的通信系统、独立工作在非授权频谱的系统如MultiFire系统等。在图1所示的网络结构中，网络设备101覆盖的范围存在工作在授权频谱上的主小区和工作在非授权频谱上的辅助小区，主小区和辅助小区的网络设备101可以对应于同一个或者两个不同的物理站点(例如，宏基站和微基站)，不同的站点可以进行通信。终端设备111～112通过接入辅助小区使用非授权频段。终端设备111～112可以是1)有数据需要发送的终端设备；2)需要重传数据的终端设备；3)没有上行数据的空闲终端设备，等。
图2示出了本发明实施例提供的一种无线装置800和无线装置900的示意性框图。无线装置800和无线装置900可以用于实现本发明各实施例的方法。无线装置800可以是图1中的网络设备101，也可以是网络设备101实现通信功能的部件。无线装置900可以是图1中的终端设备111～112，也可以是终端设备111～112实现通信功能的部件。
无线装置800、900分别包括处理器810、910。所述处理器810用于生成承载了待发送的信息的基带信号，以及用于对接收到的基带信号进行处理。无线装置800、900还可以包括与处理器810、910通过线路连接的收发器820、920，收发器820、920用于将所述处理器810、910生成的基带信号进行处理以转换成射频信号，和对通过天线接收到的射频信号进行处理以转换成所述处理器可处理的基带信号。例如，当所述无线装置800为网络设备101时，可以包括所述处理器810和收发器820。当所述无线装置900为终端设备111～112时，可以包括所述处理器910和收发器920。
图3a给出了一种确定控制信道位置的方法的示意图。网络设备可以是图1中的网络设备101，终端设备可以是图1中的终端设备111～112中的一个。
S301,网络设备给终端设备发送非授权频带集合配置信息。相应的，终端设备接收所述非授权频带集合配置信息。非授权频带集合包括至少一个非授权频带。通过非授权频带集合配置信息，将非授权频带集合中的所有非授权频带配置成终端设备的辅助频带。
非授权频带集合配置信息可以包括如下信息中的一项或多项：
-非授权频带集合中每个非授权频带的索引号(Index)；
-非授权频带集合中每个非授权频带的中心频点；
-非授权频带集合中每个非授权频带的标识。如物理小区标识(Physical Cell Identifier,PCI)；
非授权频带可以承载控制信道资源。为了节省控制信道资源开销，有些非授权频带可以不承载控制信道资源。即，为了节省控制信道资源开销，非授权频带集合中的一部分非授权频带承载控制信道资源，另一部分非授权频带不承载控制信道资源。
当非授权频带集合中的一个或多个非授权频带上需要承载控制信道资源，则非授权频带集合配置信息还可以包括：承载控制信道资源的一个或多个非授权频带上的控制信道资源配置信息。控制信道资源用于传输上行或下行控制信令。比如，控制信道资源配置信息可以是增强物理下行控制信道(Enhanced Physical Downlink Control Channel，EPDCCH)对应的控制信道资源配置信息。或者，控制信道资源配置信息可以是控制资源集合(Control Resource Set，CORSET)对应的控制信道资源配置信息。比如，如图3a所示，控制信道资源配置信息用于配置非授权频带集合中的非授权频带1，2上承载控制信道资源。
当下行控制信令是调度信息时，下行控制信令可以指示承载该下行控制信令的非授权频带上的数据资源；还可以指示另外一个非授权频带上的数据资源，即交叉调度。比如，如图3a所示，非授权频带1的控制信道资源上传输的下行控制信息(如调度信息)，可以用于指示非授权频带1上的数据资源。非授权频带2(如Index＝2)的控制信道资源传输的下行控制信息(如调度信息)，可以用于指示非授权频带2上的数据资源，或者可以用于指示非授权频带0上的数据资源(即，交叉调度)。
需要指出的是，本发明各实施例中，非授权频带i可以表示非授权频带的序号(或索引，或标识)为i。比如，非授权频带1表示序号(或索引，或标识)为1的非授权频带。为了描述方便，以下采用非授权频带i的方式进行描述。
S302,网络设备监听非授权频带集合中的非授权频带，即在配置的非授权频带上执行LBT操作。
比如，如图3a所示，假设非授权频带集合包括4个非授权频带，分别是非授权频带0～非授权频带3。网络设备在非授权频带0，1，2，3上执行LBT操作。当监听到至少一个非授权频带可用时(比如，非授权频带0，1，2可用)，网络设备确定该至少一个非授权频带中的部分(如非授权频带0，2)或全部(如非授权频带0，1，2)为可用的非授权频带集合。网络设备使用该可用的非授权频带集合中的至少一个非授权频带发送和/或接收控制信令和/或数据。
S303,网络设备向终端设备发送指示信息，指示可用的非授权频带集合信息。相应的，终端设备接收所述指示信息。
具体的，网络设备通过LBT，获得可用的非授权频带集合，然后将可用的非授权集合信息发送给终端设备。比如，网络设备监听到非授权频带0，1，2可用。即，网络设备获得可用的非授权频带集合为非授权频带0，1，2。网络设备通过指示信息通知终端设备非授权频带0，1，2。
一种实现方式中(方式1)，所述指示信息可以是参考信号，终端可以根据所述参考信号获得可用的非授权频带集合。具体的，终端设备可以盲检测非授权频带集合中的每个非授权频带上是否有所述参考信号，来确定非授权频带是否可用。如果在一个非授权频带上检测到参考信号，则说明该非授权频带是可用 的。参考信号可以为小区公共参考信号或者终端设备特定的参考信号，不作具体限定。另一种实现方式中(方式2)，所述指示信息可以是非授权频带集合中的每个承载控制信道资源的非授权频带上传输的物理层控制信息(如下行控制信息(Downlink Control Information，DCI)，终端设备可以盲检测非授权频带集合中的每个承载控制信道资源的非授权频带上是否有物理层控制信息，确定非授权频带是否可用。即，在方式2中，终端设备只需要盲检测非授权频带集合中的每个承载控制信道资源的非授权频带上是否存在物理层控制信息是否存在即可确定非授权频带是否可用。而不需要根据物理层控制信息的内容来确定非授权频带是否可用。另一种实现方式(方式3)所述指示信息还可以是在授权频带上传输或者可用的非授权频带上传输的控制信息。该控制信息可以是物理层控制信息，或者高层控制信息。终端设备接收到控制信息后，根据控制里的内容确定可用的非授权频带集合。即，在方式3中，终端设备通过控制信息中包括的内容(如控制信息中明确指示了非授权频带0，1，2是可用的)确定可用的非授权频带集合。
S304,网络设备与终端设备使用可用的非授权频带集合中的至少一个非授权频带进行通信。
比如，如图3a所示，网络设备可以在非授权频带2的控制信道资源上发送控制信息(如调度信息)，所述控制信息用于指示终端设备在非授权频带2上接收或发送数据；相应的，终端设备在非授权频带2的控制信道资源上接收控制信息，并根据所述控制信息终端设备在非授权频带2上接收或发送数据。网络设备还可以在非授权频带2的控制信道资源上发送控制信息(如调度信息)，所述控制信息用于指示终端设备在非授权频带0上接收或发送数据；相应的，终端设备在非授权频带2的控制信道资源上接收控制信息，并根据所述控制信息终端设备在非授权频带0上接收或发送数据。
又比如，网络设备可以在非授权频带2的控制信道资源上发送控制信息(如调度信息)，所述控制信息用于指示终端设备在非授权频带2及其它可用的非授权频带上接收或发送数据；相应的，终端设备在非授权频带2的控制信道资源上接收控制信息，并根据所述控制信息终端设备在非授权频带2及其它可用的非授权频带上接收或发送数据。数据可以在非授权频带2及其它可用的非授权频带上联合传输。比如，假设可用的非授权频带为0，1，2，传输一个数据传输块(Transmission Block，TB)所使用的时频资源可以同时分布在非授权频带0，非授权频带1和非授权频带2上(可以看为宽带数据传输的一种传输方式)。
图3a所示的方法的问题是，当承载控制信道资源的非授权频带不可用时，即使有其它非授权频带可用，网络设备与终端设备也无法通过可用的非授权频带进行通信。即，当可用的非授权频带集合中，没有包括承载控制信道资源的非授权频带，网络设备与终端设备也无法通过可用的非授权频带进行通信。如图3c所示，非授权频带2承载控制信道资源。可用的非授权频带集合包括非授权频带0，1。此时，网络设备无法通过非授权频带2的控制信道资源发送控制信息(如调度信息)。因此，网络设备无法调度非授权频带0和1上的数据资源。
一方面，影响数据传输，另一方面，可用的非授权频带上数据资源又没有充分利用。
图4a提供了本发明实施例的另一种确定控制信道位置的方法。本实施例中的网络设备可以是图1中的网络设备101，终端设备可以是111～112中的任意一个。
S401,网络设备确定非授权频带集合。
其中，所述非授权频带集合包括A个非授权频带，A为正整数。
需要说明的是，在本发明实施例中，非授权频带集合中包括的A个非授权频带。A个非授权频带可以是网络设备能够同时工作的非授权频带，也可以是网络设备为终端设备配置的非授权频带。其中为终端设备配置的非授权频带个数不大于网络设备能够同时工作的非授权频带。例如，假设网络设备能够同时工作的非授权频带为X个。在一种实现方式中，网络设备可以将这X个非授权频带都配置给终端设备，即A＝X。在另外一种方式中，网络设备可以只将X个非授权频带中的A个非授权频带配置给终端设备，即A<X。
在一种实现方式中，网络设备101中的处理器810可用于确定非授权频带集合。
S402，网络设备向终端设备发送指示所述非授权频带集合的配置信息。相应的，终端设备接收网络设备发送的指示所述非授权频带集合的配置信息。
所述指示所述非授权频带集合的配置信息包括如下信息中的至少一项：
-指示A个非授权频带的序号或索引号(Index)；
-指示A个非授权频带的标识；比如，物理小区标识(Physical Cell Identifier,PCI)；
-指示A个非授权频带的频点(或频率)信息；比如，频点信息可以是中心频点。
-指示A个非授权频带的带宽的信息；比如，每个非授权频带的带宽大小，如10MHz，20MHz等。
-指示非授权频带集合包括的非授权频带的数量信息；比如，该集合中，包括A个非授权频带。
-指示非授权频带集合的带宽的信息，比如，该集合的总带宽是多少。
-指示A个非授权频带优先级信息，比如优先级为0，1，2等。该优先级信息用于后续步骤S410和/或步骤S510确定控制信道资源组属于哪个非授权频带。
指示所述非授权频带集合的配置信息可以通过无线资源控制(Radio Resource Control，RRC)层，介质访问控制(Media Access Control，MAC)层，或物理层来发送，本发明不作限定。当所述指示所述非授权频带集合的配置信息通过RRC层发送时，所述指示所述非授权频带集合的配置信息可以是专用RRC消息或者系统广播消息。
需要说明的，指示所述非授权频带集合的配置信息可以在授权频带上发送。或者指示所述非授权频带集合的配置信息可以在任意一个能够传输该指示所述非授权频带集合的配置信息的非授权频带上发送。比如，假如通过执行本发明实施例，终端设备和网络设备已经可以通过非授权频带(如非授权频带0)传输控制信息和数据，则网络设备可以在非授权频带0发送所述指示所述非授权频带集合的配置信息，为终端设备配置新的非授权频带集合。本发明不作限制。
在一种实现方式中，网络设备的收发器820用于发送指示所述非授权频带集合的配置信息。或者，网络设备的处理器810控制收发器820发送指示所述非授权频带集合的配置信息。
在一种实现方式中，终端设备的收发器920可用于接收指示所述非授权频带集合的配置信息。或者终端设备的处理器910控制收发器920接收指示所述非授权频带集合的配置信息。
S403，终端设备确定非授权频带集合。
终端设备根据接收到的指示所述非授权频带集合的配置信息，确定非授权频带集合。
在一种实现方式中，终端设备111或112中的处理器910可用于确定非授权频带集合。
S404,网络设备向终端设备发送第二指示信息。相应的，终端设备接收所述第二指示信息。
所述第二指示信息用于指示D个控制信道资源组，每个所述控制信道资源组包括一个或多个控制信道资源集合，D为正整数。需要说明的是，控制信道资源组中的一个或多个控制信道资源集合在后续步骤S408和S410中，或者在S509和S510中，总是被确定属于同一个可用的非授权频带。即，网络设备和终端设备总是以控制信道资源组的粒度确定控制信道资源集合所属的非授权频带。当控制信道资源组只包括一个控制信道资源集合时，控制信道资源组与控制信道资源集合表示的信息相同。或者，此时，控制信道资源组为控制信道资源集合。相应的，第二指示信息用于指示控制信道资源组，可以理解为，第二指示信息用于指示控制信道资源集合。
需要说明的是，本发明各实施例中，控制信道资源集合表示传输控制信令的资源的集合。控制信令可以是物理层控制信令。一个控制信道资源集合上可以承载(或传输)多个控制信令。但是，一个控制信令只能在同一个控制信道资源集合上传输。即，同一个控制信令不能占用两个或多个控制信道资源集合。
控制信道资源集合可以是承载LTE系统中的增强物理下行控制信道(Enhanced Physical Downlink Control Channel,EPDCCH)的资源的集合。控制信道资源集合也可以承载5G(NR)系统中的物理下行控 制信道的控制资源集合(Control Resource Sets，CORSET)。控制信道资源集合还可以是承载其它无线接入技术的其它控制信道的资源的集合，本发明不作限制。
具体的，第二指示信息可以包括如下信息中的至少一项：
(1)指示控制信道资源组的序号(或索引，或标识)，或优先级的信息。
(2)指示控制信道资源组数量的信息，如D个控制信道资源组。
(3)指示每个控制信道资源组中包括的一个或多个控制信道资源集合的信息。针对每个控制信道资源集合，第二指示信息还可以包括如下信息中的至少一项：
(3-1)指示控制信道资源集合占用的时频资源的大小的信息；
(3-2)指示控制信道资源集合在非授权频带内的相对位置信息。
(3-3)指示控制信道资源集合对应的解调参考信号信息。
(3-4)指示控制信道资源集合是否为第一控制信道资源集合的信息,和/或控制信道资源是否为第二控制信道资源集合的信息。
(3-5)指示控制信道资源集合的序号(或索引，或标识)。
(3-6)指示控制信道资源集合的图案(Pattern)。比如，周期信息。
下面针对信息(1),(2),(3-1)至(3-5)分别进行描述。
信息(1)用于指示控制信道资源组的序号(或索引，或标识)，和/或优先级的信息。每个控制信道资源组可用拥有一个序号(或索引，或标识)，和/或优先级的信息。比如序号(或索引，或标识)是0等。该序号可以标识一个控制信道资源组。该序号可以用于在后续步骤中S410确定控制信道资源组所属的非授权频带。该序号可以是显式的序号信息。该序号也可以是由各个控制信道资源组在第二指示信息中出现的顺序来隐式表示。优先级信息可以是0，1，2等，表示不同的控制信道资源组。优先级可以用于表示在确定C个第一非授权频带时，优先为优先级较高(或较低)的控制信道资源组确定所属的非授权频带。当多个控制信道资源组优先级相同时，则可以按序号顺序(例如从高到低或从低到高)为该多个控制信道资源组确定所属的非授权频带。
信息(2)用于指示控制信道资源组数量的信息，如D＝3表示3个控制信道资源组。该数量信息可以是显式的数量信息，或者可以是控制信道资源组的个数隐式表示。
信息(3-1)可以包括：在时间上占用的时间长度单位的数量和/或在频域上占用的频域宽度单位的数量。比如，该时间长度单位可以是正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号(Symbol)，或者时隙(Slot)，或者迷你时隙(Mini Slot)，或者传输时间间隔(Transmission Time Interval，TTI)，或者子帧(Sub-Frame)，或者是子传输时间间隔(Sub Transmission Time Interval，sTTI)，或者是其它时间长度单位，本发明不作限制。该频域宽度单位可以是子载波(Sub Carrier)、资源元素(Resource Element，RE)、物理资源块(Physical Resource Block，PRB)、资源块组(Resource Block Group，RBG)、赫兹(Hz)、控制信道元素(Control Channel Element，CCE)、或者是其它频域宽度单位，本发明不作限制。可以理解的，所述时频资源的大小信息中，可以只包括时间上的大小，也可以只包括频域上的大小，当只包括其中一个信息时，另外一个信息通过其它方式获得，比如在协议中固定，或者通过其它信息获得。可选的，如果多个控制信道资源集合占用的时频资源的大小相同，则针对该多个控制信道资源集合，第二指示信息中可以只包括一个信息(3-1)。这样，可以节省第二指示信息的信令开销。
信息(3-2)用于指示各个控制信道资源集合在非授权频带内的相对位置信息。例如是控制信道资源集合在非授权频带中的起始时间位置和/或控制信道资源集合在非授权频带中的起始频域位置。起始时间位置例如是控制信道资源集合在时域上开始的符号、时隙、迷你时隙、TTI、sTTI、或者子帧开始等。起 始频域位置例如是控制信道资源集合在频域上开始的子载波、PRB、RBG、Hz等。可以理解的，所述相对位置信息中，可以只包括时间位置，也可以只包括频域位置，当只包括其中一个信息时，另外一个信息通过其它方式获得，比如在协议中固定，或者通过其它信息获得。可选的，如果多个控制信道资源集合在非授权频带内的相对位置相同，则针对该多个控制信道资源集合，第二指示信息中可以只包括一个信息(3-2)。这样，可以节省第二指示信息的信令开销。
终端设备根据信息(3-1)中指示的时频资源大小信息和/或在信息(3-2)中指示的在非授权频带内的相对位置信息，可以确定各个控制信道资源集合实际占用的时域资源和/或频域资源。比如，一个控制信道资源集合在时间上从一个子帧的第1个OFDM符号开始，占用2个符号。即，一个控制信道资源集合在时间上占用一个子帧的第一个和第二个OFDM符号。和/或，一个控制信道资源集合在频域上从第1个PRB开始，占用4个PRB。即，一个控制信道资源集合在域域上用于第一个PRB至第四个PRB。可以理解的，当一个控制信道资源集合在频域上占用多个PRB时，该多个PRB在频域上可以是连续的PRB，也可以是不连续的PRB，本发明不作限制。
信息(3-3)用于指示各个控制信道资源集合对应的解调参考信号信息。终端设备使用解调参考信号进行信道估计。然后终端设备在控制信道资源集合接收下控制信息。进一步的，在不同的控制信道资源集合上传输下行控制信道时使用的解调参考信号可以相同，也可以不同。可选的，如果多个控制信道资源集合使用的解调参考信号相同，则针对该多个控制信道资源集合，第二指示信息中可以只包括一个信息(3-3)。这样，可以节省第二指示信息的信令开销。
信息(3-4)用于指示各个控制信道资源集合是否为第一控制信道资源集合的信息。和/或信息(3-4)用于指示各个控制信道资源集合是否为第二控制信道资源集合的信息。或者，信息(3-4)用于指示各个控制信道资源组是否为第一控制信道资源组的信息。和/或信息(3-4)用于指示各个控制信道资源组是否为第二控制信道资源组的信息。第一控制信道资源组表示该控制信道资源组中包括的所有的控制信道资源集合均为第一控制信道资源集合。第二控制信道资源组表示该控制信道资源组中包括的所有的控制信道资源集合均为第二控制信道资源集合。
针对一个特定终端设备，如终端设备111，第一控制信道资源集合包括如下特征：
-网络设备通过第一控制信道资源集合向终端设备111发送下行控制信息(如调度信息)。终端设备111通过第一控制信道资源集合接收下行控制信息。
-当承载终端设备111的数据的时频资源(或称为数据资源)与第一控制信道资源集合冲突(如第一控制信道资源集合占用的时频资源中的至少一部分与承载终端设备111的数据的时频资源的一部分重叠)，则在发生冲突的时频资源上，网络设备不传输终端设备111的数据。此时，网络设备在将数据映射到时频资源时，将绕过发生冲突的时频资源。该特征可以称为速率匹配。这样，可以保证在第一控制信道资源集合上传输的的下行控制信息的可靠性。或者，在发生冲突的时频资源上，网络设备将终端设备111的数据进行打孔(puncture)。此时，网络设备在将数据映射到时频资源时，不绕过发生冲突的时频资源，但会将应该映射到发生冲突的时频资源上的数据丢弃。相应的，终端设备可以不处理在该冲突的时频资源上承载的信息。该特征可以称为打孔。这样，可以简化网络设备的数据处理过程。
针对一个特定终端设备，如终端设备111，第二控制信道资源集合包括如下特征：
-第二控制信道资源集合不能用于传输终端设备111的下行控制信息
-当承载终端设备111的数据的时频资源(或称为数据资源)与第二控制信道资源集合冲突(如第二控制信道资源集合占用的时频资源中的至少一部分与承载终端设备111的数据的时频资源的一部分重叠)，则在发生冲突的时频资源上，网络设备不传输终端设备111的数据。此时，网络设备在将数据映射到时频资源时，将绕过发生冲突的时频资源。该特征可以称为速率匹配。这样，可以保证在第二控制信道资源集 合上传输的其它终端设备的下行控制信息的可靠性。或者，在发生冲突的时频资源上，网络设备将终端设备111的数据进行打孔(puncture)。此时，网络设备在将数据映射到时频资源时，不绕过发生冲突的时频资源，但会将应该映射到发生冲突的时频资源上的数据丢弃。相应的，终端设备可以不处理在该冲突的时频资源上承载的信息。该特征可以称为打孔。这样，可以简化网络设备的数据处理过程。
配置给终端设备111的第二控制信道资源集合可以与配置给终端设备112的第一控制信道资源集合相同。即，同一个控制信道资源集合对于一个终端设备来说，是第一控制信道资源集合，而对于另外一个终端设备来说，是第二控制信道资源集合。
通常,第二指示信息中指示的一个或多个控制信道资源集合是由一个或多个第一控制信道资源集合,和/或,一个或多个第二控制信道资源集合组成。
信息(3-5)用于指示控制信道资源的序号(或索引，或标识)。每个控制信道资源集合可用拥有一个序号(或索引，或标识)，和/或优先级的信息。比如序号(或索引，或标识)是0，1，2等。该序号可以标识一个控制信道资源集合。同一个控制信道资源组中包括的多个控制信道资源集合的序号不同。不同控制信道资源组中包括的控制信道资源集合的序号可以相同。该序号可以是显式的序号信息。该序号也可以是由各个信道资源集合在一个控制信道资源组中出现的顺序来隐式表示。一种控制信道资源集合的序号的实现方式是，基于该控制信道资源集合所在的控制信道资源组进行编号。另一种控制信道资源集合的序号的实现方式是，是可以基于配置的所有控制信道资源组包括的所有控制信道资源集合进行编号。比如，假设有两个控制信道资源组，每个控制信道资源组有2个控制信道资源集合。此时，一种控制信道资源集合的序号的实现方式是，第一个控制信道资源组中的2个控制信道资源集合编号为0，1；第二个控制信道资源组中的2个控制信道资源集合编号为0，1。另一种控制信道资源集合的序号的实现方式是第一个控制信道资源组中的2个控制信道资源集合编号为0，1，第二个控制信道资源组中的2个控制信道资源集合编号为2，3。
信息(3-6)为指示控制信道资源集合的图案。具体的，该图案可以是周期。周期可以是M个时间单元，M为正整数。时间单元，可以是一个符号、时隙、迷你时隙、TTI、sTTI、或者子帧，也可以是其他表达形式，不作具体限定。
第二指示信息可以通过无线资源控制(Radio Resource Control，RRC)层控制信令，介质访问控制(Media Access Control，MAC)层控制信令，或物理层来控制信令发送，本发明不作限定。当所述第二指示信息通过RRC层控制信令发送时，所述第二指示信息可以是专用RRC消息或者系统广播消息。可以理解的，本步骤404的第二指示信息和步骤402中的信息可以在相同的消息中发送，也可以在不同的消息中发送。本发明不作限制。需要指示的是，本步骤S404的第二指示信息和步骤S406的信息可以在相同的消息中发送，或者，本步骤S404的第二指示信息在步骤S406之后发送。
需要说明的，第二指示信息可以在授权频带上发送。或者第二指示信息可以在任意一个能够传输该第二指示信息的非授权频带上发送。比如，假如通过执行本发明实施例，终端设备和网络设备已经可以通过非授权频带(如非授权频带0)传输控制信息和数据，则网络设备可以在非授权频带0发送所述第二指示信息，为终端设备配置新的控制信道资源组。本发明不作限制。
本步骤S404中，控制信道资源组并不被半静态(或固定)的配置成属于一个特定的非授权频带。控制信道资源组属于哪个非授权频带是通过后续步骤S408和S410，或者S509和S510来确定的。
网络设备中的收发器820用于发送所述第二指示信息。或者网络设备中的处理器810控制收发器820发送所述第二指示信息。
终端设备中的收发器920可用于接收所述第二指示信息。或者，终端设备中的处理器910控制收发器920接收所述第二指示信息。
S405,网络设备确定可用的非授权频带集合。
所述可用的非授权频带集合包括B个非授权频带，且所述可用的非授权频带集合是所述非授权频带集合的子集；B为正整数。
具体的，网络设备监听非授权频带集合，即在配置的非授权频带集合中包括的A个非授权频带中的至少一个上执行LBT操作。。
通过LBT，网络设备获得(或确定)可用的非授权频带集合。即，网络设备获得哪些非授权频带是可用的。
可选的，网络设备还可以不执行LBT，而是通过终端设备或其它网络设备提供的信息来获得可用的非授权频带集合。
网络设备的处理器810可用于执行LBT，即监听非授权频带集合。或者，网络设备的处理器810控制收发器820执行LBT。
S406,网络设备给终端设备发送第四指示信息。相应地，终端设备接收第四指示信息。所述第四指示信息用于指示可用的非授权频带集合。
所述第四指示信息可以是参考信号。例如网络设备在确定某个非授权频带可用的时候，可以在该非授权频带上发送参考信号，终端设备如果在配置的某个非授权频带上检测到该参考信号，则说明该非授权频带为可用的非授权频带。所述参考信息可以小区特定参考信号(Cell-specific Reference signal,CRS)，其中CRS是接入该网络设备的所有终端设备都能够识别的参考信号，或者终端特定的参考信号(UE-Specific Reference signal)。参考信号包括但不限于：信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS),解调参考信号(Demodulation Reference Signal，DM-RS)，NR系统中使用的参考信号例如用于物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的DMRS、用于PDSCH的相位跟踪参考信号(Phase Tracking Reference Signal，PT-RS)、用于PDCCH的DMRS、用于物理广播信道(Physical Broadcast Channel)的DMRS、同步信号(Synchronization Signal)。比如，网络设备可以在可用的非授权频带集合中的所有非授权频带上发送CRS，具体的，可以在每个可用的非授权频带上发送的相同的CRS，或者每个可用的非授权频带上发送的不同的CRS，或者一部分可用的非授权频带上发送的CRS不同于另外一部分可用的非授权频带上发送的CRS。其他参考信号也可以用上述方式发送和确定，不作具体描述。
第四指示信息可以是前导序列(Preamble)，网络设备可以在可用的非授权频带集合中的所有可用的非授权频带上发送前导序列，具体的，可以在每个可用的非授权频带上发送的相同的前导序列，或者每个可用的非授权频带上发送的不同的前导序列，或者一部分可用的非授权频带上发送的前导序列不同于另外一部分可用的非授权频带上发送的前导序列。
所述第四指示信息还可以是控制信息，例如是通过无线资源控制(Radio Resource Control，RRC)层，介质访问控制(Media Access Control，MAC)层，或物理层来发送的控制信息，本发明不作限定。当所述第四指示信息是通过RRC层发送的控制信息时，所述第四指示信息可以是专用RRC消息或者系统广播消息。
当所述第四指示信息是控制信息时，一种实现方式是，第四指示信息包括可用的非授权频带集合中每个非授权频带的序号(或索引号)或标识)。所述序号(或索引号)或标识为步骤402中的指示所述非授权频带集合的配置信息中包括的序号(或索引号)或标识。比如，非授权频带集合中的非授权频带0(即，非授权频带的序号或标识为0)为可用的非授权频带，非授权频带2为可用的非授权频带，非授权频带3为可用的非授权频带，等。这种指示序号的方式的好处是，当非授权频带集合中包括的非授权频带的数量比较多，而可用的非授权频带集合包括的非授权频带的数量比较少时，可以节省第四指示信息的信令开销。
当所述第四指示信息是控制信息时，另外一种实现方式是第四指示信息可以采用位图的方式，指示可用的非授权频带集合。位图中的每比特对应一个所述非授权频带集合中的一个非授权频带。位图中某个比特值为1代表对应的非授权频带是可用的非授权频带；比特值为0代表对应的非授权频带是不是可用的非授权频带。当图4b用于第四指示信息的示例时，图4b示出了从MSB至LSB分别与A个非授权频带按序号从低到高的顺序一一对应的示例。如图4b所示，假设非授权频带集合包括4个非授权频带，表示为非授权频带0至非授权频带3，即A＝4。位图包括4个比特，左边第一个为最高比特(most Significant Bit，MSB)，右边第一个为最低位(Least Significant Bit，LSB)。位图中第一比特(MSB)至第四比特(LSB)与非授权频带集合的非授权频带0至非授权频带3对应。如图4b所示，非授权频带0，1，3可用，非授权频带2不可用(如图中用斜线表示)。此时位图取值为1101。即网络设备通过将位图设置成1101可以表示非授权频带0，1，3可用，非授权频带2不可用。相应的，终端设备通过位图的取值1101，即可以获得可用的非授权频带集合包括非授权频带0，1，3。当图4c用于第四指示信息的示例时，图4c示出了从MSB至LSB分别与A个非授权频带按序号2，0，3，1的顺序一一对应的示例。如图4c所示，假设非授权频带集合包括4个非授权频带，表示为非授权频带0至非授权频带3。位图中第一比特(MSB)至第四比特(LSB)分别与非授权频带集合的非授权频带2，0，3，1对应。非授权频带0，1，3可用，非授权频带2不可用(如图中用斜线表示)。此时位图取值为0111。即网络设备通过将位图设置成0111可以表示非授权频带0，1，3可用，非授权频带2不可用。相应的，终端设备通过位图的取值0111，即可以获得可用的非授权频带集合包括非授权频带0，1，3。可以理解，位图中各个比特也可以按照其他顺序(如从LSB至MSB的顺序)与A个非授权频带对应，本发明不作限制。还可以理解，A个非授权频带可以按其它顺序与位图中各个比特(从MSB至LSB或从LSB至MSB)对应，本发明不作限制。具体的对应关系可以在协议中固定，或者通过网络设备发送控制信息通知给终端设备。
采用位图的好处是，非授权频带集合中的每个非授权频带只需要1比特来表示，当非授权频带集合中包括的非授权频带的数量比较多和/或可用的非授权频带集合中包括的非授权频带的数量比较多时，可以节省第四指示信息的信令开销。
第四指示信息可以通过无线资源控制(Radio Resource Control，RRC)层控制信令，介质访问控制(Media Access Control，MAC)层控制信令，或物理层来控制信令发送，本发明不作限定。当所述第四指示信息通过RRC层控制信令发送时，所述第四指示信息可以是专用RRC消息或者系统广播消息。
需要说明的，第四指示信息可以在授权频带上发送。或者第四指示信息可以在任意一个能够传输该第四指示信息的非授权频带上发送。比如，假如通过执行本发明实施例，终端设备和网络设备已经可以通过非授权频带(如非授权频带0)传输控制信息和数据，则网络设备可以在非授权频带0发送所述第四指示信息，通知终端设备新的可用的非授权频带集合。
进一步的，可以通过小区公共的无线网络临时标识(Radio Network Temporary Identifier，RNTI)对所述第四指示信息进行加扰，或者通过UE特定的RNTI对所述第四指示信息进行加扰。
网络设备中的收发器820可用于发送所述第四指示信息。或者，网络设备中的处理器810控制收发器820发送所述第四指示信息。
终端设备中的收发器920可用于接收所述第四指示信息。或者，终端设备中的处理器910控制收发器920发送所述第四指示信息。
S407，终端设备确定所述可用的非授权频带集合。
终端设备可以根据所述第四指示信息确定所述可用的非授权频带集合。
具体而言，当所述第四指示信息是参考信号时，终端设备可以根据所述参考信号获得可用的非授权频带集合，即获得哪个非授权频带可用。也就是说，终端设备可以根据参考信号的有无来确定可用的非授权 频带集合。
当第四指示信息是前导序列(Preamble)时，可以根据所述前导序列获得可用的非授权频带集合，即获得哪个非授权频带可用。也就是说，终端设备可以根据前导序列的有无来确定可用的非授权频带集合。
当所述第四指示信息是控制信息时，终端设备通过读取所述控制信息确定所述可用的非授权频带集合。
在一种实现方式中，终端设备的处理器910可用于确定所述可用的非授权频带集合。
S408,网络设备在所述可用的非授权频带集合中确定C个第一非授权频带，所述第一非授权频带上包括控制信道，C为正整数。即，所述第一非授权频带上承载D个控制信道组中的至少一个控制信道资源组。
网络设备可以结合各个可用的非授权频带的负载，干扰，或网络设备的资源管理策略等因素，来确定所述C个第一非授权频带。网络设备确定所述可用的非授权频带集合中的C个第一非授权频带上均承载控制信道资源组。即网络设备确定D个控制信道资源组中的至少C个属于所述C个第一非授权频带中的一个非授权频带。
一种实现方式中(方式1)，第i个控制信道资源组属于第i个第一非授权频带，1≤i≤C；
另一种实现方式中(方式2)，第j个控制信道资源组属于第((j-1)mod C)+1个第一非授权频带，1≤j≤D。
上述方式2的公式中(j-1)mod C，含义是(j-1)除以C取余数，本发明各实施例中的Mod均是两数相除取余的意思，以后不再赘述。
按照上述方式1，如果确定的C大于或等于D，则确定所有D个控制信道资源组中的每一个都能属于一个第一非授权频带。如果确定的C小于D，则确定前C个控制信道资源组属于一个第一非授权频带。此时，后(D-C)个控制信道资源组可以不属于任何一个第一非授权频带。按照上述方式2，可以确定D个控制信道资源组中的每个都属于一个第一非授权频带。并且，当D大于C时，可以确定有两个或多个控制信道资源组属于同一个第一非授权频带。当D小于或等于C时，方式1和方式2效果相同。
在一种具体实现方式中，所述第1个至第D个控制信道资源组为按照序号或优先级从低到高的顺序；或者，所述第1个至第D个控制信道资源组为按照序号或优先级从高到低的顺序。
在一种具体实现方式中，所述第1个至第C个第一非授权频带为按照频率或序号从低到高的顺序；或者
所述第1个至第C个第一非授权频带为按照频率或序号从高到低的顺序；或者
当所述第四指示信息是位图时，所述第1个至第C个第一非授权频带为为按照第四指示信息从最高位对应的非授权频带至最低位对应的非授权频带的顺序；或者
当所述第四指示信息是位图时，所述第1个至第C个第一非授权频带为为按照第四指示信息从最低位对应的非授权频带至最高位对应的非授权频带的顺序；或者
所述第1个至第C个第一非授权频带为按照在第一指示信息中的位置从前到后的顺序；或者
所述第1个至第C个第一非授权频带为按照在第一指示信息中的位置从后到前的顺序；或者
当步骤S409中的第一指示信息是位图时，所述第1个至第C个第一非授权频带为按照第一指示信息从最高位对应的非授权频带至最低位对应的非授权频带的顺序；或者
当步骤S409中的第一指示信息是位图时，所述第1个至第C个第一非授权频带为按照第一指示信息从最低位对应的非授权频带至最高位对应的非授权频带的顺序；
当步骤S409中的第一指示信息包括C个第一非授权频带的序号(或索引号，或标识)时,所述第1个至第C个第一非授权频带为按照第一指示信息C个第一非授权频带的序号在第一指示信息中的先后位置的顺序。第一指示信息的具体信息，请参见S409。
在一种实现方式中，网络设备中的处理器810可用于确定C个第一非授权频带。
S409,网络设备向终端设备发送第一指示信息，所述第一指示信息用于指示所述确定的C个第一非授权频带。相应的，终端设备接收第一指示信息。
具体的，网络设备通过授权频带向终端设备发送第一指示信息；或者
网络设备通过所述可用的非授权频带集合中的至少一个非授权频带向终端设备发送第一指示信息；或者
网络设备通过所述确定的C第一非授权频带中的至少一个非授权频带向终端设备发送第一指示信息。下面以使用一个非授权频带向终端设备发送第一指示信息为例，对第一指示信息包括的内容进行描述。
在一种实现方式中，所述第一指示信息为位图，所述位图包括至少一个比特。下面给出了第一指示信息是位图的4种实现方式。在4种方式中的的任一种实现方式中，位图中的比特值为1，表示该比特对应的非授权频带为第一非授权频带。即，比特值为1，表示该比特对应的非授权频带上承载D个控制信道资源组中的至少一个控制信道资源组。位图中的比特值为0，表示该比特对应的非授权频带不是第一非授权频带，和/或表示该比特对应的非授权频带不承载D个控制信道资源组中的任何一个控制信道资源组，和/或表示该比特对应的非授权频带是不可用的非授权频带(即该比特对应的非授权频带不属于可用的非授权频带集合)。
所述位图的第一种实现方式是(方式1)，所述至少一个比特为A个比特，所述位图的A个比特与所述A个非授权频带对应。这种实现方式的好处是，每个非授权频带只需要用一个比特表示，信令开销比较小。另外位图包括的比特数量与非授权频带集合的数量相同，因此位图包括的比特数量固定，有利于降低处理复杂度。
例如(方式1-1)，所述位图中从最高位(MSB)至最低位(LSB)分别与A个非授权频带按频率或优先级或序号从低到高的顺序一一对应；或者所述位图中从MSB至LSB分别与A个非授权频带按频率或优先级或序号从高到低的顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与A个非授权频带对应，方式类似。当图4b用于第一指示信息的示例时，图4b示出了从MSB至LSB分别与A个非授权频带按序号从低到高的顺序一一对应的示例，图4b中一个方框代表一个比特。假设A＝4，B＝3,C＝2,D＝2，非授权频带集合包括的非授权频带的序号为0,1,2,3。可用的非授权频带集合中的非授权频带的序号为0，2，3。发送所述第一指示信息的非授权频带序号为2(如图中用斜线填充来表示)。网络设备确定非授权0和2为第一非授权频带。则图4b中示出的各个比特取值为1010。其中，1010对应的非授权频带分别为0、1、2、3。
又例如(方式1-2)，所述位图中，从MSB到LSB方向为所述位图的第1比特至第A比特。第1比特与发送所述第一指示信息的非授权频带对应。第2比特至第B比特分别与B个可用非授权频带中除发送所述第一指示信息的非授权频带以外的非授权频带按频率或优先级或序号从低到高(或从高到低)的顺序一一对应。第B+1比特至第A比特分别与A个非授权频带中除B个可用非授权频带以外的非授权频带按频率或优先级或序号从低到高(或从高到低)的顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与A个非授权频带对应，方式类似。当图4c用于第一指示信息的示例时,图4c给出了从MSB至LSB分别与A个非授权频带对应的另一个示例，图4c中一个方框代表一个比特。如图4c所示，假设非授权频带集合包括非授权频带0，1，2，3，即A＝4。可用非授权频带集合包括非授权频带0，2，3，即B＝3。C＝2,D＝2。网络设备利用非授权频带2发送第一指示信息。此时，位图中第1比特与非授权频带2对应(如图中用斜线填充来表示)。第2比特至第3比特分别与非授权频带0，3对应(按可用的非授权频带集合中的非授权频带的序号从低到高的顺序)。第4比特与非授权频带1对应(不可用的非授权频带)。网络设备确定非授权0和2为第一非授权频带。则图4c中示出的各个比特取值为1100。
又例如(方式1-3)，所述位图中，从MSB到LSB方向为所述位图的第1比特至第A比特。第1比特至 第x比特分别与从发送所述第一指示信息的非授权频带开始的x个非授权频带，按频率或序号从低到高(或从高到低)的顺序一一对应，其中第x比特与频率或序号最高(或最低)的非授权频带对应。第x+1比特至第A比特分别与A-x个非授权频带按频率或序号从低到高的顺序一一对应。x为正整数且x小于或等于A。可以理解的，所述位图也可以从LSB至MSB与A个非授权频带对应，方式类似。比如，假设非授权频带集合包括非授权频带0，1，2，3，即A＝4。可用的非授权频带集合包括非授权频带0，2，3，即B＝3。C＝2,D＝2。网络设备利用非授权频带2发送第一指示信息。此时，位图中第1比特与非授权频带2对应。第2比特与非授权频带3对应。第3比特与非授权频带0对应。第4比特与非授权频带1对应。网络设备确定非授权0和2为第一非授权频带。则位图中各个比特取值为1100。
可以理解，位图中各个比特也可以按照其他顺序(如从LSB至MSB的顺序)与A个非授权频带对应，本发明不作限制。还可以理解，A个非授权频带可以按其它顺序与位图中各个比特(从MSB至LSB或从LSB至MSB)对应，本发明不作限制。具体的对应关系可以在协议中固定，或者通过网络设备发送控制信息通知给终端设备。
所述位图的第二种实现方式(方式2)是，所述位图包括A-1个比特，所述A-1个比特与A-1个非授权频带相对应，所述A-1个非授权频带为所述A个非授权频带中除发送所述第一指示信息的第一非授权频带以外的非授权频带，所述A个比特的取值用于指示对应的非授权频带是否为所述第一非授权频带。这种实现方式的好处是，每个非授权频带只需要用一个比特表示，信令开销比较小。另外位图包括的比特数量与非授权频带集合的数量相同，因此位图包括的比特数量固定，有利于降低处理复杂度。由于表示发送所述第一指示信息的第一非授权频带的比特取值恒为1，因此，不需要在位图中包括与该发送所述第一指示信息的第一非授权频带对应的比特。与方式1相比，信令开销更小。
例如(方式2-1)，所述位图中从最高位(MSB)至最低位(LSB)分别与A个非授权频带中除发送所述第一指示信息的非授权频带以外的非授权频带按频率或优先级或序号从低到高(或从高到低)的顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与A个非授权频带对应，方式类似。当图4b用于第一指示信息的示例时，方式2与方式1的区别为，方式2中的位图中不包括与非授权频带2对应的比特(如图中用斜线填充来表示)。当采用与方式1相同的假设时，方式2中的位图的取值为100。
又例如(方式2-2)，所述位图中，从MSB到LSB方向为所述位图的第1比特至第A-1比特。从MSB开始，第1比特至第B-1比特，分别与B个可用非授权频带中除发送所述第一指示信息的非授权频带以外的非授权频带按频率或优先级或序号从低到高((或从高到低))的顺序一一对应，从MSB开始的第B比特至第A-1比特，分别与A个非授权频带中除B个可用非授权频带以外的非授权频带按频率或优先级或序号从低到高的((或从高到低))顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与A个非授权频带中除发送所述第一指示信息的非授权频带以外的非授权频带对应，方式类似。当图4c用于第一指示信息的示例时，方式2与方式1的区别为，方式2中的位图中不包括与非授权频带2对应的比特(如图中用斜线填充来表示)。当采用与方式1相同的假设时，方式2中的位图的取值为100。
又例如(方式2-3)，所述位图中，从MSB到LSB方向为所述位图的第1比特至第A-1比特。第1比特至第x比特分别与从发送所述第一指示信息的非授权频带(但不包括发送所述第一指示信息的非授权频带)开始的x个非授权频带，按频率或序号从低到高(或从高到低)的顺序一一对应，其中第x比特与频率或序号最高(或最低)的非授权频带对应。第x+1比特至第A-1比特分别与A-x个非授权频带按频率或序号从低到高的顺序一一对应。x为正整数且x小于或等于A-1。可以理解的，所述位图也可以从LSB至MSB与A-1个非授权频带对应，方式类似。比如，假设非授权频带集合包括非授权频带0，1，2，3，即A＝4。可用的非授权频带集合包括非授权频带0，2，3，即B＝3。C＝2,D＝2。网络设备利用非授权频带2发送第一指示信息。此时，位图中第1比特与非授权频带3对应。第2比特与非授权频带0对应。第3比特与非授权频带 1对应。第4比特与非授权频带2对应。网络设备确定非授权0和2为第一非授权频带。则位图中各个比特取值为100。
可以理解，位图中各个比特也可以按照其他顺序(如从LSB至MSB的顺序)与A-1个非授权频带对应，本发明不作限制。还可以理解，A-1个非授权频带可以按其它顺序与位图中各个比特(从MSB至LSB着从LSB至MSB)对应，本发明不作限制。具体的对应关系可以在协议中固定，或者通过网络设备发送控制信息通知给终端设备。
所述位图的第三种实现方式(方式3)是，所述位图包括B个比特。所述B个比特分别与所述B个可用的非授权频带相对应。所述位图每个比特的取值用于指示对应的非授权频带是否为所述第一非授权频带。该方式相比方式1相比，方式3中的位图不携带与不可用的非授权频带对应的比特，因此能节省更多的信令开销。
例如(方式3-1)，所述位图中从最高位(MSB)至最低位(LSB)分别与B个可用的非授权频带按频率或优先级或序号从低到高(或从高到低)的顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与B个可用的非授权频带对应，方式类似。图4d示出了从MSB至LSB分别与B个可用的非授权频带按序号从低到高的顺序一一对应的示例，图4b中一个方框代表一个比特。假设A＝4，B＝3，C＝2，D＝2。非授权频带集合包括的非授权频带的序号为0,1,2,3。可用非授权频带集合中的非授权频带的序号为0，2，3。2个第一非授权频带的序号为0，2。发送所述第一指示信息的非授权频带序号为2(如图中用斜线填充来表示)。则图4d中示出的各个比特取值为110。
又例如(方式3-2)，所述位图中，从MSB到LSB方向为所述位图的第1比特至第B比特。从MSB开始，第1比特与发送所述第一指示信息的非授权频带对应。第2比特至第B比特，分别与B个可用非授权频带中除发送所述第一指示信息的非授权频带以外的非授权频带按频率或优先级或序号从低到高((或从高到低))的顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与B个可用非授权频带对应，方式类似。图4e示出了从MSB至LSB分别与B个可用的非授权频带对应的又一个示例，图4e中一个方框代表一个比特。假设A＝4，B＝3，C＝2，D＝2。非授权频带集合包括的非授权频带的序号为0,1,2,3。可用非授权频带集合中的非授权频带的序号为0，2，3。2个第一非授权频带的序号为0，2。发送所述第一指示信息的非授权频带序号为2(如图中用斜线填充来表示)。则图4e中示出的各个比特取值为110。
又例如(方式3-3)，所述位图中，从MSB到LSB方向为所述位图的第1比特至第B比特。第1比特至第x比特分别与从发送所述第一指示信息的非授权频带开始的x个可用非授权频带，按频率或优先级或序号从低到高(或从高到低)的顺序一一对应，其中第x比特与频率或优先级或序号最高(或最低)的可用非授权频带对应。第x+1比特至第B比特分别与B-x个可用非授权频带按频率或优先级或序号从低到高的顺序一一对应。x为正整数且x小于或等于B。可以理解的，所述位图也可以从LSB至MSB与B个非授权频带对应，方式类似。比如，假设A＝4，B＝3，C＝2，D＝2。非授权频带集合包括的非授权频带的序号为0,1,2,3。可用的非授权频带集合中的非授权频带的序号为0，2，3。2个第一非授权频带的序号为0，2。发送所述第一指示信息的非授权频带序号为2。则位图中各个比特取值为101。
可以理解，位图中各个比特也可以按照其他顺序(如从LSB至MSB的顺序)与B个可用非授权频带对应，本发明不作限制。还可以理解，B个可用非授权频带可以按其它顺序与位图中各个比特(从MSB至LSB着从LSB至MSB)对应，本发明不作限制。具体的对应关系可以在协议中固定，或者通过网络设备发送控制信息通知给终端设备。
所述位图的第四种实现方式(方式4)是，所述位图包括B-1个比特，所述B-1个比特分别与B-1个非授权频带相对应。所述B-1个非授权频带为所述B个可用的非授权频带中除发送所述第一指示信息的第一非授权频带以外的非授权频带。所述B-1个比特的取值用于指示对应的非授权频带是否为所述第一非授权 频带。由于表示发送所述第一指示信息的第一非授权频带的比特取值恒为1，因此，不需要在位图中包括与该发送所述第一指示信息的第一非授权频带对应的比特。与方式3相比，信令开销更小。
例如，所述位图中从最高位(MSB)至最低位(LSB)分别与B个可用非授权频带中除发送所述第一指示信息的非授权频带以外的非授权频带按频率或优先级或序号从低到高(或从高到低)的顺序一一对应。可以理解的，所述位图也可以从LSB至MSB与B个可用的非授权频带对应，方式类似。以图4d或图4e为例，方式4与方式3的区别为，方式4中的位图中不包括与非授权频带2对应的比特(如图中用斜线填充来表示)。当采用与方式3相同的假设时，方式4中的位图的取值为10。
可以理解，位图中各个比特也可以按照其他顺序(如从LSB至MSB的顺序)与B-1个可用的非授权频带对应，本发明不作限制。还可以理解，B-1个可用的非授权频带可以按其它顺序与位图中各个比特(从MSB至LSB着从LSB至MSB)对应，本发明不作限制。具体的对应关系可以在协议中固定，或者通过网络设备发送控制信息通知给终端设备。
需要说明的是，采用方式1-2或方式2-2与其它实现方式相比，可以降低系统复杂度，同时提升非授权频带资源的利用效率。具体原因包括：(1)方式1-2或方式2-2中位图包括的比特个数只与第一非授权频带集合相关。(2)无论利用哪个可用的非授权频带发送第一指示信息，网络设备发送的第一指示信息的内容(即位图中各个比特的取值)可以不变。以图4c为例，假设A＝4，C＝2，D＝2。此时位图各比特取值为1100，可以应用于如图4f至图4h所示的任一场景。其中，在图4f所示场景中，网络设备通过非授权频带0发送所述位图，在图4g所示场景中，网络设备通过非授权频带3发送所述位图，在图4h所示场景中，网络设备通过非授权频带3发送所述位图。
当所述第一指示信息为位图时，本发明实施例的另外一种实现方式是，网络设备先执行步骤S408，后执行步骤S406。即网络设备先设置C值及位图的取值，然后通过监听确定了B。但是B<C，此时，位图中第B+1及第B个之后取值为1的比特会被终端设备忽略。以图4c为例，位图取值为1100时且只有一个可用非授权频带时(即B＝1)时，针对如图4f至图4h任一所示的场景中，终端设备空山鸟语忽略第2比特(第2个取值为1的比特)，这样，可以保证网络设备和终端设备理解一致。此时，采用方式1-2或方式2-2与其它实现方式相比，可以降低系统复杂度，同时提升非授权频带资源的利用效率。
可以理解的，所述位图不仅限于上述4种实现方式。可以理解的，具体采用上述方式1至方式4中的哪种实现方式，可以通过协议固定，或者网络设备通过系统消息，RRC消息，MAC层消息，或者物理层消息通知给终端设备，本发明不作限制。
从系统角度，非授权频带的数量可能会大于配置给一个终端设备的非授权频带集合中包括的非授权频带的数量A，因此，为了进一步简化系统设计，位图包括的比特数有可能是比A还要大的一个固定值。此时，该终端设备只需要考虑该位图中与通过步骤S402获得的非授权频带集合中的非授权频带对应的比特即可。即终端设备忽略不属于非授权频带集合的非授权频带对应的比特。或者，此时，该终端设备只需要考虑该位图中与通过步骤S402获得的非授权频带集合中的除发送所述第一指示信息的非授权频带之外的非授权频带对应的比特即可。或者，此时，该终端设备只需要考虑该位图中与通过步骤S406获得的可以的非授权频带集合中的非授权频带对应的比特即可。或者，此时，该终端设备只需要考虑该位图中与通过步骤S406获得的可以的非授权频带集合中除发送所述第一指示信息的非授权频带之外的非授权频带对应的比特即可。比如，系统支持最多同时使用5个非授权为终端设备服务，则位图可以包括5个比特。假如一个终端设备的，A＝4，则位图中的一个比特，比如最后一个(LSB)对于该终端设备来是不可用的，即终端设备会忽略该比特。可以理解的，终端设备忽略位图中的哪个比特或哪些比特，可以在协议中定义相应规则，或者网络设备通知给终端设备。
在另一种实现方式中，所述第一指示信息包括C个第一非授权频带的序号(或索引号，或标识)。所 述序号(或索引号，或标识)为在步骤S402中配置信息中的序号。关于序号(或索引号，或标识)的具体介绍请参考步骤S402。终端设备通过第一指示信息中的C个序号，可以确定C个第一非授权频带。
第一指示信息可以通过RRC层控制信息，MAC层控制信息，物理层控制信息来发送，本发明不作限定。当使用RRC层控制信息时，可以是专用RRC消息或者系统广播消息。
在一种实现方式中，网络设备中的收发器820可用于发送所述第一指示信息。或者，网络设备中的处理器810控制收发器820发送所述第一指示信息。
在一种实现方式中，终端设备的收发器920可用于接收所述第一指示信息。或者，终端设备的处理器910控制收发器920接收所述第一指示信息。
S410,终端设备在所述可用非授权频带集合中确定C个第一非授权频带，所述第一非授权频带上包括控制信道。即，所述第一非授权频带上承载D个控制信道组中的至少一个控制信道资源组。
当第一指示信息是位图时，终端设备根据位图，确定所述C个第一非授权频带。当第一指示信息包括C个非授权频带的序号(或索引号，或标识)时，终端设备根据C个序号，确定所述C个第一非授权频带。
一种实现方式中(方式1)，第i个控制信道资源组属于第i个第一非授权频带，1≤i≤C；
另一种实现方式中(方式2)，第j个控制信道资源组属于第((j-1)mod C)+1个第一非授权频带，1≤j≤D。
具体实现方式与网络设备相同。请参考步骤S408，在此不作赘述。
在一种实现方式中，终端设备中的处理器910可用于确定所述C个第一非授权频带。
S411,网络设备与终端设备使用可用非授权频带集合中的至少一个非授权频带进行通信。
网络设备使用第一非授权频带上的包括的控制信道资源组中的控制信道资源集合向终端设备发送下行控制信息。下行控制信息中包括为终端设备调度的下行数据资源信息或上行数据资源信息。相应的，终端设备使用第一非授权频带上包括的控制信道资源组中的控制信道资源集合接收网络设备发送的下行控制信息。终端设备使用所述下行控制信息中通知的下行数据资源接收下行数据或在所述下行控制信息中通知的上行数据资源上发送上行数据。
可以理解的，如步骤S404中的描述，用于指示数据资源的下行控制信息在第一控制信道资源集合上传输。当终端设备在第一非授权频带上的数据资源与第一非授权频带上的包括的控制信道资源集合冲突，则在冲突的资源上不传输终端设备的数据。
在一种实现方式中，网络设备的处理器810和收发器820可用于完成通信。
在一种实现方式中，终端设备的处理器910和收发器920可用于完成通信。
可以理解的，通过执行本发明实施例步骤S401至步骤S410，网络设备和终端设备可以动态确定承载D个控制信道资源组中的至少一个的第一非授权频带。从而实现步骤S411的通信的目的。因此，步骤S411可选。
可以理解的，步骤S402中的指示所述非授权频带集合的配置信息与S404中的第二指示信息可以通过不同消息发送，也可以相同消息发送，本发明不作限制。
可以理解的，本发明实施例各步骤并不限制执行顺序，任一可以达到本发明实施例目的的顺序均在本发明保护范围之内。网络设备和终端设备通过执行本发明实施例所述方法，虽然可用非授权频带集合包括的非授权频带随着时间不断变化，但是网络设备和终端设备可以动态确定承载D个控制信道资源组中的至少一个的第一非授权频带，即确定控制信道的位置，从而实现正常通信的目的。避免了由于半静态配置的控制信道资源所属的非授权频带不可用而导致不能进行正常通信的问题。
图5给出了本发明实施例另一个确定控制信道位置的方法的流程示意图。
本发明实施例中，S501～S504分别与S401～S404相同，在此不作赘述。
S505,网络设备向终端设备发送第三指示信息。相应的，终端设备接收所述第三指示信息。第三指示信息用于指示至少一个偏移量m，m为自然数，且0≤m＜A。当至少一个偏移量m的数量大于1时，每个偏移量m与D个控制信道资源组的中至少一个对应。即，此时，D个控制信道资源组的中至少一个与且只与一个m对应。比如第1个控制信道资源组使用m1，第2个控制信道资源组使用m2，第3个控制信道资源组使用m1等。m1和m2均为自然数。且0≤m1＜A，且0≤m2＜A。作为一个特例，D个控制信道资源组的D1个第一控制信道资源组可以与m1对应，D个控制信道资源组的D-D1个第二控制信道资源组可以与m2对应。
终端设备根据所述至少一个m，确定第一非授权频带。第一非授权频带上承载D个控制信道资源组中的至少一个。或者，终端设备根据所述至少一个m，确定第1个至第D个控制信道资源组中的至少一个控制信道资源组所属的第一非授权频带。
第三指示信息和第二指示信息可以承载在同一条消息或信令中，也可以承载在不同的消息或信令中。或者，第三指示信息和指示所述非授权频带集合的配置信息，可以承载在同一条消息或信令中，也可以承载在不同的消息或信令中。或者，第三指示信息，第二指示信息和指示所述非授权频带集合的配置信息可以承载在同一条消息或信令中，也可以承载在不同的消息或信令中。
第三指示信息可以通过RRC层控制信息，MAC层控制信息，物理层控制信息来发送，本发明不作限定。当使用RRC层控制信息时，可以是专用RRC消息或者系统广播消息。
一种可替换的实现方式，本步骤S505中的第三指示信息在协议中固定。即，此时，步骤S505不存在。
在一种实现方式中，网络设备的收发器820，用于发送所述第三指示信息。或者，网络设备的处理器810控制收发器820发送所述第三指示信息。
在一种实现方式中，终端设备的收发器920可用于接收所述第三指示信息。或者，终端设备的处理器910控制收发器920接收所述第三指示信息。S506,网络设备确定可用非授权频带集合。S506与S405相同，不再赘述。
S506，网络设备确定所述可用的非授权频带集合。S506与S405相同，不再赘述。
S507,网络设备给终端设备发送第四指示信息，所述第四指示信息用于指示可用非授权频带集合或可用非授权频带。S507与S406相同，不再赘述。
S508，终端设备确定所述可用非授权频带集合。S508与S407相同，不再赘述。
S509,网络设备在所述可用非授权频带集合中确定C个第一非授权频带，所述第一非授权频带上包括控制信道，C为正整数。
当m≤B时，网络设备根据至少一个偏移量m，确定C个第一非授权频带包括所述可用非授权频带集合中第(m+1)个非授权频带。由于网络设备在确定B个可用非授权频带之前确定m，因此有可能出现m≥B。此时，网络设备根据至少一个偏移量m，确定C个第一非授权频带包括所述可用非授权频带集合中第(m+1)mod B个非授权频带。所述第(m mod B)+1个非授权频带为所述B个可用的非授权频带按照频率或序号从低到高的顺序下的第(m mod B)+1个非授权频带；或者，所述第(m mod B)+1个非授权频带为所述B个非授权频带按照频率或序号从高到低的顺序下的第(m mod B)+1个非授权频带。关于频率或序号的信息的介绍，请参考步骤S502。可以理解的，无论m≤B，还是m≥B，网络设备均可以根据至少一个偏移量m，确定C个第一非授权频带包括所述可用的非授权频带集合中第(m+1)mod B个非授权频带。比如，假设m＝1，B＝4，则所述C个第一非授权频带包括第(m mod B)+1＝2个可用非授权频带。再比如，假设m＝4，B＝2，则所述C个第一非授权频带包括第(m mod B)+1＝1个可用非授权频带。
一种实现方式(方式1)是，第j个控制信道资源组属于第((j+m-1)mod B)+1个可用的非授权频带，1≤j≤D。所述第1个至第D个控制信道资源组为按照序号或优先级从低到高的顺序；或者，所述第1 个至第D个控制信道资源组为按照序号或优先级从高到低的顺序。当D≤B时，所述确定的C个第一非授权频带包括所述可用的非授权频带集合的D个，即C＝D。当D≥B时，所述确定的C个第一非授权频带包括所述可用的非授权频带集合的B个。此时，网络设备可以确定B个可用的非授权频带都是第一非授权频带，即C＝B。例如，假设D＝4，即第二指示信息中包括4个控制信道资源组，m＝1，B＝3，则第1个控制信道资源组属于第((j+m-1)mod B)+1＝2个可用非授权频带；第2个控制信道资源组属于第((j+m-1)mod B)+1＝3个可用非授权频带；第3个控制信道资源组属于第((j+m-1)mod B)+1＝1个可用非授权频带；第4个控制信道资源组属于第((j+m-1)mod B)+1＝2个可用非授权频带。
该方式1能为所有控制信道资源组确定所属的第一非授权频带，但是有可能出现多个控制信道资源组属于同一个第一非授权频带的情况。因此，该多个控制信道资源组的资源有可能发生冲突(或者多个控制信道资源组包括的控制信道资源集合的资源有可能发生冲突)。此时发生冲突的多个控制信道资源组中的部分控制信道资源组或者全部控制信道资源组被认为是不可用的(或者发生冲突的多个控制信道资源集合被认为是不可用的)。具体的，发生冲突的多个控制信道资源组，序号或优先级较低(或较高)的控制信道资源组被认为是不可用的。即，此时，该控制信道资源组中的控制信道资源集合不用于传输终端设备的下行控制信息。再比如，发生冲突的多个控制信道资源集合，序号或优先级较低(或较高)的控制信道资源组中的控制信道资源集合不用于传输终端设备的下行控制信息。
另一种实现方式(方式2)基于实现方式1。与方式1不同的是，第j+1个至第D个控制信道资源组不属于B个可用的非授权频带中的任何一个。其中j满足如下条件：第((j+m-1)mod B)+1＝B。比如，假设D＝4，即第二指示信息中包括4个控制信道资源组，m＝1，B＝3，当确定第1个和第2个控制信道资源组所属的第一非授权频带之后，即j＝2时，((j+m-1)mod B)+1＝3＝B。此时，第3个控制信道资源组至第3个控制信道资源组不属于任何一个非授权频带。方式2简单，但可能会导致可用的控制信道资源组数量受限。
另一种实现方式(方式3)基于实现方式1。与方式1不同的是，第j+1个至第D个控制信道资源组不属于B个可用的非授权频带中的任何一个。其中j满足如下条件：j＝B。比如，假设D＝4，即第二指示信息中包括4个控制信道资源组，m＝1，B＝3，当确定第1个和第2个控制信道资源组所属的第一非授权频带之后，即j＝2时，((j+m-1)mod B)+1＝3，第j＝3个控制信道资源组所属的第一非授权频带为((j+m-1)mod B)+1＝1,即第3个控制信道资源组属于第1个可用的非授权频带。此时，j＝B。因此，第4个控制信道资源组不属于任何一个非授权频带。相比方式2，可以有更多控制信道资源组可用。但又不会出现方式中中多个控制信道资源组属于同一个第一非授权频带的情况。
上述方式1，方式2，方式3中，当j>1时，第j个控制信道资源组属于第((j+m-1)mod B)+1个可用的非授权频带可以替换为第j个控制信道资源组属于第((j+m-1+x)mod B)+1个可用的非授权频带，1≤j≤D，x为自然数。即，网络设备可以间隔X个非授权频带确定包括的控制信道资源组。比如，假设D＝2，m＝1，B＝3,x＝1，网络设备确定第1个(即j＝1)控制信道资源组属于第((j+m-1)mod B)+1＝2个可用的非授权频带。网络设备确定第2个(即j＝2)控制信道资源组属于第((j+m-1+x)mod B)+1＝1个可用的非授权频带。x可以是协议固定，也可以通过RRC层控制信息，MAC层控制信息，物理层控制信息来发送，本发明不作限定。RRC层控制信息可以是专用RRC消息或者系统广播消息。
当m的数量大于1时，上述方式1，方式2，方式3中，第j个控制信道资源组属于第((j+m-1)mod B)+1个可用的非授权频带，1≤j≤D，可以替换为第j个与m对应的控制信道资源组属于第((j+m-1)mod B)+1个可用的非授权频带，1≤j≤D。
具体采用上述方式1，方式2，方式3中的哪一种方式，可以在协议中固定，或者网络设备通过RRC层消息，MAC层消息，或者物理层消息通知给终端设备。当通过RRC层消息通知时，可以是系统消息，或 者专用RRC消息。本发明不作限制。
第三指示信息在协议中固定时，本步骤S509也可以按步骤S408方式1和/或方式2的实现方式实现。比如，假设非授权频带集合包括非授权频带0，1，2，3，即A＝4。可用的非授权频带集合包括非授权频带0，2，3，即B＝3。C＝2，D＝2。第1个控制信道资源组属于非授权频带0，第2个控制信道资源组属于非授权频带2。当D<B时，D个控制信道资源组与B个可用的非授权频带中的D个按频率或序号从低到高的顺序一一对应。
在一种实现方式中，网络设备中的处理器810可用于确定C个第一非授权频带。
S510,终端设备在所述可用的非授权频带集合中确定C个第一非授权频带，所述第一非授权频带上包括控制信道。
所述终端设备根据第三指示信息中的至少一个偏移量m和第四指示信息，确定所述C个第一非授权频带。
终端设备本步骤操作与S509中网络设备的操作是对应，以保证终端设备与网络侧设备的理解是一致的。具体请参考步骤S509。
在一种实现方式中，终端设备的处理器910可用于确定C个第一非授权频带。
S511,网络设备与终端设备使用可用的非授权频带集合中的至少一个非授权频带进行通信。S511与S411相同，不再赘述。
可以理解的，本发明实施例各步骤并不限制执行顺序，任一可以达到本发明实施例目的的顺序均在本发明保护范围之内。
网络设备和终端设备通过执行本发明实施例所述方法，虽然可用的非授权频带集合包括的非授权频带随着时间不断变化，但是网络设备和终端设备可以动态确定承载D个控制信道资源组中的至少一个的第一非授权频带，即确定控制信道的位置，从而实现正常通信的目的。避免了由于半静态配置的控制信道资源所属的非授权频带不可用而导致不能进行正常通信的问题。
本发明的另一个确定控制信道位置的方法的实施例包括如下步骤：
S601～S608分别与S401～S408相同，在此不作赘述。
S609,网络设备向终端设备发送第五指示信息，相应的，终端设备接收第五指示信息。所述第五指示信息用于指示所述确定的C个第一非授权频带。
第五指示信息的发送方法与步骤409中第一指示信息的发送方法相同，不再赘述。
在一种实现方式中，所述第五指示信息中包括D个控制信道资源组中的至少一个控制信道资源组及其所属的第一非授权频带的信息。比如第五指示信息包括：第1个控制信道资源组，属于可用的非授权频带1(或可用的非授权频带的序号为1)；第2个控制信道资源组，属于可用的非授权频带3(或可用的非授权频带的序号为3)。
再比如第五指示信息包括：
第1个控制信道资源组，属于第1个非授权频带(或非授权频带的序号为1)；
第2个控制信道资源组，属于第3个非授权频带(或非授权频带的序号为3)。
在另一种实现方式中，第五指示信息可以只包括非授权频带的序号信息。此时，第一个控制信道资源组属于第五指示信息中的第一个出现的非授权频带的序号对应的非授权频带，第二个控制信道资源组属于第五指示信息中的第二个出现的非授权频带的序号对应的非授权频带，等等。同一个序号可以出两次或多次。此时，序号对应的非授权频带包括多个控制信道资源组。相比第一种实现方式第五指示信息的信令开销会比较小。
在第三种实现方式中，第五指示信息可以只包括一个第一序号，该第一序号对应的非授权频带包括第 一个控制信道资源组。然后，第2个至第D个控制信道资源组属于从第一序号开始按照序号从低到高(或从高到低)的顺序确定的可用的非授权频带。此时，该第一序号与实施例5中的偏移量m作用相同。具体的实现方式与实施例5中的S506类似，在此不作赘述。
在第四种实现方式中第五指示信息可以是参考信号信息。第五指示信息使用的参考信号不同于第四指示信息使用的参考信号。网络设备在所有包括控制信道资源组的可用的非授权频带上发送第五指示信息(即参考信号)。在所有发送第五指示信息(即参考信号)的可用的非授权频带(即第一非授权频带)中，非授权频带序号或频率最低(或最高)的可用的非授权频带包括第一个控制信道资源组。第i个控制信道资源组属于第i个发送第五指示信息的可用的非授权频带。所述第1个至第C个发送第五指示信息的非授权频带为按照频率或序号从低到高的顺序；或者所述第1个至第C个发送第五指示信息的非授权频带为按照频率或序号从高到低的顺序。参考信息可以小区特定参考信号(Cell-specific Reference signal,CRS)，其中CRS是接入该网络设备的所有终端设备都能够识别的参考信号，或者终端特定的参考信号(UE-Specific Reference signal)。参考信号包括但不限于：CSI-RS,DM-RS,NR系统中使用的参考信号例如用于PDSCH的DMRS、用于PDSCH的相位跟踪参考信号PT-RS、用于PDCCH的DMRS、用于物理广播信道(Physical Broadcast Channel)的DMRS、同步信号(Synchronization Signal)等。
在一种实现方式中，网络设备中的收发器820可用于发送第五指示信息。或者，网络设备的处理器810控制收发器820发送第五指示信息。
在一种实现方式中，终端设备的收发器920接收第五指示信息。或者，网络设备的处理器910控制收发器920发送第五指示信息。
S610,终端设备在所述可用的非授权频带集合中确定C个第一非授权频带，所述第一非授权频带上包括控制信道。
具体的，所述终端设备根据第五指示信息和第四指示信息，确定所述C个第一非授权频带。
终端设备本步骤操作与S608中网络设备的操作是对应，以保证终端设备与网络侧设备的理解是一致的。具体请参考步骤S609。
在一种实现方式中，终端设备的处理器910可用于确定C个第一非授权频带。
网络设备和终端设备通过执行本发明实施例所述方法，虽然可用的非授权频带集合包括的非授权频带随着时间不断变化，但是网络设备和终端设备可以动态确定承载D个控制信道资源组中的至少一个的第一非授权频带，即确定控制信道的位置，从而实现正常通信的目的。避免了由于半静态配置的控制信道资源所属的非授权频带不可用而导致不能进行正常通信的问题。
