Description

一种时隙格式指示方法、设备及系统 技术领域
本申请涉及通信技术领域，特别涉及一种时隙格式指示方法、设备及系统。
背景技术
长期演进(long term evolution，LTE)中规定一个分量载波(component carrier，CC)的带宽最大可以达到20MHz，然而随着通信技术的不断发展，20MHz的带宽已经不能够满足长期演进高级(long term evolution advanced，LTE-A)系统下行峰速1Gbps，上行峰速500Mbps的要求，为此引入了载波聚合(carrier aggreation，CA)技术。
具体的，CA技术指的是将2个或者更多个CC聚合在一起来支持更大的传输带宽，其中LTE-A系统中对于一个终端设备来说，最多支持5个CC，然而在下一代无线通信(next radio，NR)系统中，对于一个终端设备来说，上下行分别最多支持16个CC。
然而，基站在为终端设备配置了多个CC后，还需要向终端设备指示各个CC的时隙格式信息(slot format information，SFI)，终端设备才能够在CC上实现数据的发送和接收，现有技术中通常情况下基站是基于下列方式向终端设备指示CC的SFI的：当基站为终端设备配置了多个CC时，基站通过将各个CC的时隙格式信息(slot format information，SFI)分别承载在各自CC上的group common物理下行控制信道(physical downlink control channel，PDCCH)上发送给终端设备，或者基站通过多个CC中的一个CC上的group common PDCCH上携带这多个CC的SFI发送给终端设备，示例的，基站为终端设备配置了CC1、CC2和CC3，基站可以通过CC1上的group common PDCCH向终端设备发送CC1的SFI，通过CC2上的group common PDCCH向终端设备发送CC2的SFI，通过CC3上的group common PDCCH向终端设备发送CC3的SFI，或者基站通过CC1、CC2和CC3中其中一个CC上的group common PDCCH向终端设备发送CC1的SFI、CC2的SFI和CC3的SFI。由于上述向终端设备指示时隙格式的方式中各个CC的SFI是单独指示的，容易导致信令开销较大。
发明内容
本发明实施例提供一种时隙格式指示方法、设备及系统，有助于在一定程度上降低时隙格式指示时的信令开销。
第一方面，本申请实施例提供了一种时隙格式指示方法，该方法包括：网络设备生成第一指示信息，并向终端设备发送第一指示信息，其中第一指示信息指示K个时隙格式，该K个时隙格式为配置给终端设备的M个CC的时隙格式，其中K个时隙格式中的至少一个时隙格式对应M个CC中的至少两个CC，该至少两个CC的配置参数中的至少一种参数相同，K为大于等于且小于等于M的整数，M为大于1的整数，配置参数包括子载波检核、循环前缀、带宽和频段中的至少一种参数。
由于配置参数中的至少一种参数相同的CC可以通过第一指示信息中指示的K个时隙格式中的一个时隙格式指示给终端设备，因而与将每个CC的时隙格式单独指示给终端设备相比，在一定程度上有助于降低时隙格式指示时的信令开销。
需要说明的是，在本申请实施例中的M个CC可以是连续的频域资源，也可以是不连续的频域资源，对此本申请实施例不作限定。
示例的，M取值为4，配置给终端设备的4个CC分别为CC1、CC2、CC3和CC4，假设CC1的子载波间隔、CC2的子载波将和CC3的子载波间隔均为15KHz，CC4的子载波间隔为30KHz，则在本申请实施例中第一指示信息可以指示子载波间隔为15KHz对应的时隙格式和30KHz对应的时隙格式，其中子载波间隔为15KHz对应的时隙格式对应CC1、CC2和CC3，子载波间隔为30KHz对应的时隙格式对应CC4，或者第一指示信息可以指示子载波间隔为15KHz对应的时隙格式、15KHz对应的时隙格式和30KHz对应的时隙格式，其中示例的一个子载波间隔为15KHz对应的时隙格式对应CC1和CC2，另一个子载波间隔为15KHz对应的时隙格式对应CC3，子载波间隔为30KHz对应的时隙格式对应CC4。
此外，示例的，当M取值为2，配置给终端设备的2个CC分别为CC1和CC2时，假设CC1的子载波间隔为15KHz，CC2的子载波间隔为30KHz，在这种情况下，第一指示信息可以指示子载波间隔为15KHz对应的时隙格式和30KHz对应的时隙格式。
在具体实现时，第一指示信息一种可能的设计为：第一指示信息包括H个域，H个域中的K个域分别指示K个时隙格式中的一个时隙格式，H为大于等于K的正整数。通过上述技术方案有助于简化第一指示信息的实现方式。
为了便于终端设备能够准确读取第一指示信息，一种可能的设计为：网络设备向终端设备发送第一配置信息后，在向终端设备发送第一指示信息，其中第一配置信息包括或者指示下列信息中的至少一种：
H的值、H个域中的每一个域对应的参数和可配置的一个或多个时隙格式。
在具体实现时，第一指示信息另一种可能的设计为：第一指示信息指示第一时隙格式组合方式，其中第一时隙格式组合方式为K种参数对应的时隙格式组合，其中K为M个CC对应的参数的种类数。通过上述技术方案有助于降低第一指示信息的信令开销。
在具体实现时，本申请实施例中网络设备向终端设备发送第一指示信息的一种可能的设计为：网络设备在M个CC中的N个CC上发送第一指示信息，N为大于等于1的整数，且N小于等于M。其中当N取值为1时，上述技术方案有助于减少终端设备的盲检次数，从而降低功耗。当N取值大于1小于M时，上述技术方案有助于在一定程度上减少终端设备的盲检次数的同时提高第一指示信息传输的可靠性；当N取值为M时，上述技术方案能够最大程度提高第一指示信息传输的可靠性。
需要说明的是，通常情况下网络设备是在N个CC上的group common PDCCH上发送的。
具体的，网络设备在M个CC中的N个CC上发送第一指示信息，一种可能的设计为：网络设备分别在N个CC上发送第一指示信息，即网络设备在N个CC中的每个CC上发送一个完整的第一指示信息，通过上述技术方案有助于提高第一指示信息传输的可靠性；另一种可能的设计为：网络设备分别在N个CC上发送部分第一指示信息，由N个部分第一指示信息组成一个完整的第一指示信息，通过上述技术方案有助于降低第一指示信息的信令开销。
此外，在本申请实施例中为了使得终端设备确定传输第一指示信息的CC的个数以及传输第一指示信息的CC是哪些，在一种可能的设计中，网络设备向终端设备发送第二配置信息，其中第二配置信息用于配置N、以及N个CC。
另一种可能的设计为：预定义N的值，具体的采用M个CC中的哪些CC，由网络设备 确定后，通知给终端设备，在这种情况下，第二配置信息中可以只包括N个CC，示例的，M取值为3时，为终端设备配置的CC分别为CC1、CC2、CC3，假设预定义N的值为1，网络设备若采用CC1向终端设备发送第一指示信息，则第二配置信息中包括CC1。
其中，特别的，当N＝M时，由于M个CC均可以用来发送第一指示信息，因此在该种情况下，第二配置信息中可以不用包括N个CC。
在一种可能的设计中，M个CC中包括的各个CC的时隙格式，处于相同时域位置上的传输方向不同时出现上行和下行。通过上述技术方案有助于避免上下行的相互干扰，还有助于降低第一指示信息的信令开销。

由于配置参数中的至少一种参数相同的CC可以通过第一指示信息中指示的K个时隙格式中的一个时隙格式指示给终端设备，因而与将每个CC的时隙格式单独指示给终端设备相比，在一定程度上有助于降低时隙格式指示时的信令开销。
在具体实现时，第一指示信息一种可能的设计为：第一指示信息包括H个域，H个域中的K个域分别指示K个时隙格式中的一个时隙格式，H为大于等于K的正整数。通过上述技术方案有助于简化第一指示信息的实现方式。

在具体实现时，第一指示信息另一种可能的设计为：第一指示信息指示第一时隙格式组合方式，其中第一时隙格式组合方式为K种参数对应的时隙格式组合，其中K为M个CC对应的参数的种类数。通过上述技术方案有助于降低第一指示信息的信令开销。
在具体实现时，本申请实施例中终端设备接收网络设备发送的第一指示信息的一种可能的设计为：终端设备接收网络设备在M个CC中的N个CC上发送的第一指示信息，N为大于等于1的整数，且N小于等于M。其中当N取值为1时，上述技术方案有助于减少终端设备的盲检次数，从而降低功耗。当N取值大于1小于M时，上述技术方案有助于在一定程度上减少终端设备的盲检次数的同时提高第一指示信息传输的可靠性；当N取值为M时，上述技术方案能够最大程度提高第一指示信息传输的可靠性。

具体实施方式
下面结合说明书附图对本申请实施例进行详细介绍。
本申请实施例中，由于配置参数中的至少一种参数相同的CC可以通过第一指示信息中指示的K个时隙格式中的一个时隙格式指示给终端设备，因而与单独指示各个CC的时隙格式相比，在一定程度上有助于降低时隙格式指示信息的信令开销。
应理解，本申请实施例中所涉及的网络设备，可以是基站、或者接入点，或者可以是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。当网络设备为基站时，基站可用于将收到的空中帧与网际协议(internet protocol，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IP网络。基站还可用于协调对空中接口的属性管理。例如，基站可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)系统中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的节点B(node B)，还可以是长期演进(long term evolution，LTE)系统中的演进型基站(evolutional node B，eNB)，亦或是下一代无线通信(next radio，NR)系统中的第五代移动通信技术(5th generation，5G)节点(g node B，gNB)，本申请实施例不作限定。
应理解，本申请实施例中所涉及的终端设备可以为用于向用户提供语音和/或数据连通性的设备、或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。本申请实施例中的终端设备还可以为无线终端，其中，无线终端可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)、或具有移动终端的计算机，例如，具有移动终端的计算机可以是便携式、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，无线终端还可以为个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)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，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户装备(user equipment)等，本申请实施例不作限定。
应理解，本申请实施例所涉及的时隙又称为slot，为传输数据的资源在时域上的单位，一个时隙通常包含多个符号/码片，每个符号/码片可能有相同或不同的传输方向。
应理解，本申请实施例所涉及的时隙格式又称为slot format，用于指示时隙包括的符号/码片的个数、符号的大小、在时隙上各个符号/码片承载的内容、以及各个符号/码片的传输方向等信息。示例的，假设一个时隙包括14个符号，时隙格式可能的情况可以如图1所示，其中图1中所示的时隙格式仅为举例说明，在实际的通信系统中，可能只使用图1中所示的时隙格式中的部分或全部，还可能使用除此之外其他类型的时隙格式，本申请实施例中对此不作限定。
应理解，本申请实施例所涉及的配置参数又可称之为numerology，包括子载波间隔 (subcarrier spacing)、循环前缀(cyclic prefix，CP)、带宽和频段中的至少一种参数，其中需要说明的是，配置参数还可以包括其他参数比如快速傅里叶变换(fast fourier transformation，FFT)点数等，本申请实施例对此不作限定。其中，配置参数不同可能会导致符号的大小不同。以子载波间隔为例，若子载波间隔为15千赫兹(KHz)，则符号的大小为1/15000秒(s)，若子载波间隔为30KHz，则符号的大小为1/30000s，在NR中，通常情况下，当子载波间隔≤60KHz时，每个时隙包括的符号的个数为7个或14个；当子载波间隔>60KHz时，每个时隙包括的符号的个数为14个。
应理解，本申请实施例可以应用于NR系统、LTE系统、LTE-A系统、增强的长期演进技术(enhanced long term evolution-advanced，eLTE)等通信系统中，还可以扩展到如无线保真(wireless fidelity，WiFi)、全球微波互联接入(worldwide interoperability for microwave access，wimax)、以及第三代合作伙伴计划(3rd generation partnership project，3GPP)等相关的蜂窝系统中，具体的本申请实施例所应用的通信系统架构可以如图2a所示，一个终端设备接入一个基站，一个基站管理多个终端设备，需要说明的是，本申请实施例中不限定图2a中所示通信系统中终端设备的个数，本申请实施例所应用的通信系统架构还可以如图2b所示，一个终端设备接入多个基站，一个基站管理多个终端设备，需要说明的是，本申请实施例中不限定图2b中所示的通信系统中基站和终端设备的个数。
下面以网络设备为基站为例对本申请实施例时隙格式指示方法进行详细说明，当网络设备为其它设备时，时隙格式指示方法与网络设备为基站时时隙格式指示方法类似，在此不再赘述。
如图3所示，本申请实施例时隙格式指示方法，包括：
步骤300，基站生成第一指示信息，第一指示信息指示K个时隙格式，其中K个时隙格式为配置给终端设备的M个CC的时隙格式，K个时隙格式中的至少一个时隙格式对应M个CC中的至少两个CC，该至少两个CC的配置参数中的至少一种参数相同，K为大于等于1的整数，M为大于等于1并且小于等于K的整数。
其中配置参数包括子载波间隔、循环前缀、带宽、以及频段中的至少一种参数。
步骤301，基站向终端设备发送第一指示信息。
步骤302，终端设备在接收到基站发送的第一指示信息后，根据第一指示信息，确定M个CC的时隙格式。
示例的，配置参数包括子载波间隔和循环前缀，假设CC1的配置参数中子载波间隔为15KHz、循环前缀为普通的循环前缀；CC2的配置参数中子载波间隔为15KHz、循环前缀为扩展的循环前缀，则CC1的配置参数中的子载波间隔和CC2的配置参数中的子载波间隔相同，则CC1和CC的配置参数中的一种参数相同；若配置参数包括子载波间隔、循环前缀和带宽，假设CC1的配置参数中子载波间隔为15KHz、循环前缀为普通的循环前缀、带宽为A；CC2的配置参数中子载波间隔为15KHz、循环前缀为普通的循环前缀、带宽为B，其中A不等于B，则CC1的配置参数中的子载波间隔和CC2的配置参数中的子载波间隔相同，CC1的配置参数中的循环前缀和CC2的配置参数中的循环前缀相同，则CC1和CC的配置参数中的两种参数相同。
下面基于以下通信场景对本申请实施例进行介绍。
假设基站覆盖范围内包括终端设备a、终端设备b、终端设备c、终端设备d和终端设备f，其中基站配置给终端设备a 3个CC，分别为CC1、CC2和CC3，基站配置给终端设备b 2个CC， 分别为CC4和CC5，基站配置给终端设备c 4个CC，分别为CC6、CC7、CC8和CC9，基站配置给终端设备d 1个CC，为CC10，基站配置给终端设备f 2个CC，分别为CC11和CC12。其中，CC1至CC12可以是连续的频域资源，也可以是不连读的频域资源，对此本申请实施例不作限定。
情况一：基站分别针对不同的终端设备发送第一指示信息，具体的，基站可以将配置给同一个终端设备的CC划分为一组，以终端设备c为例，假设配置参数为子载波间隔：若CC6的子载波间隔、CC7的子载波间隔、和CC8的子载波间隔为15KHz，CC9的子载波间隔为30KHz，则第一指示信息中可以指示一个15KHz对应的时隙格式和一个30KHz对应的时隙格式，其中15KHz对应的时隙格式用于指示CC6、CC7和CC8的时隙格式，30KHz的对应的时隙格式用于指示CC9的时隙格式，此外，第一指示信息中还可以指示两个15KHz对应的时隙格式，和一个30KHz对应的时隙格式，其中一个15KHz对应的时隙格式可以用于指示CC6、CC7和CC8中其中两个CC的时隙格式，另一个15KHz对应的时隙格式用于指示CC6、CC7和CC8中另外一个CC的时隙格式；若CC6的子载波间隔为15KHz，CC7的子载波间隔为30KHz，CC8的子载波间隔为60KHz，CC9的子载波间隔为120KHz，则第一指示信息指示15KHz对应的时隙格式、30KHz对应的时隙格式、60KHz对应的时隙格式和120KHz对应的时隙格式。
情况二：基站还可以将配置给终端设备a、终端设备b、终端设备c和终端设备d的各个CC中CC的配置参数中存在至少一种配置参数相同的CC划分为一组或者多组，具体划分为几组由基站进行确定，通常情况下划分组的个数不大于配置参数中存在至少一种配置参数相同的CC的总个数，假设配置参数包括子载波间隔和循环前缀，若CC1的子载波间隔、CC4的子载波间隔和CC6的子载波间隔均为15KHz，则第一指示信息指示15KHz对应的时隙格式。
除此之外，基站对配置给终端设备a、终端设备b、终端设备c和终端设备d的各个CC还可以按照其他方式进行分组，在此不再一一介绍，当按照其他方式进行分组时，假设CC1、CC3、CC4和CC7为一组，其中CC1的子载波间隔为15KHz、CC3的子载波间隔为60KHz，CC4的子载波间隔和CC7的子载波间隔均为60KHz，则该组CC的时隙格式指示信息用于指示15KHz对应的时隙格式、30KHz对应的时隙格式和60KHz对应的时隙格式，具体的一种实现方式为：将第一指示信息即为该组CC的时隙格式指示信息；另一种实现方式为：由于对于终端设备a来说，由于基站只给终端设备a配置了CC1，因此60KHz对应的时隙格式和30KHz对应的时隙格式对于终端设备a来说是冗余信息，因此基站只需向终端设备a发送该组CC的时隙格式指示信息中的第一指示信息即可，其中第一指示信息指示15KHz对应的时隙格式。
还需要说明的是，在本申请实施例中基站对CC的分组可以是UE common的，即基站对CC的分组对于基站覆盖范围内的所有终端设备来说是相同的，示例的，基站将CC1和CC2划分为一组，则对于终端设备a来说CC1和CC2为一组，对于终端设备b来说CC1和CC2也必然为一组；在本申请实施例中基站对CC的分组还可以是UE specific，即对于终端设备a来说若CC1和CC2为一组，对于终端设备b来说CC1和CC2可能属于不同的CC组。
具体的基站可以通过无线资源控制(radio resource control，RRC)信令或者媒体访问控制(media access control，MAC)信令通知终端设备CC的分组信息(例如基站如何划分CC分组的)。
本申请实施例中，第一指示信息指示K个时隙格式，一种可能的实现方式为：
第一指示信息包括H个域，其中H个域中的K个域分别指示K个时隙格式中的一个时隙格 式，其中H为大于等于K的正整数。示例的，假设第一指示信息指示3个时隙格式，时隙格式1、时隙格式2和时隙格式3，其中子载波间隔为15KHz对应时隙格式1、子载波间隔为30KHz对应时隙格式2、子载波间隔60KHz对应时隙格式3，若H为子载波间隔的种类的总个数，例如子载波间隔的种类的总个数为5，具体的子载波间隔可以为15KHz、30KHz、60KHz、120KHz和240KHz，则H值可以取值为5，如图4a所示，域1对应15KHz、域2对应30KHz、域3对应60KHz、域4对应120KHz，域5对应240KHz，则域1用于指示时隙格式1、域2用于指示时隙格式2、域3用于指示时隙格式3，其中域4和域5为空，或者域4指示子载波间隔为120KHz对应的一种时隙格式，域5指示子载波间隔为240KHz对应的一种时隙格式。此外，H还可以为K个时隙格式的参数的种类总个数，假设第一指示信息指示3个时隙格式，时隙格式1、时隙格式2和时隙格式3，其中子载波间隔为15KHz对应时隙格式1、子载波间隔为30KHz对应时隙格式2、子载波间隔60KHz对应时隙格式3，如图4b所示，域1对应15KHz、域2对应30KHz、域3对应60KHz，则域1用于指示时隙格式1，域2用于指示时隙格式2，域3用于指示时隙格式3。
在本申请实施例中H的值、H个域中每个域对应的参数以及可配置的一个或多个时隙格式可以由基站事先配置给终端设备，或者预定义，具体的，基站向终端设备发送第一配置信息，第一配置信息包括或指示下列信息中的至少一种：H的值、H个域中的每一个域对应的参数、可配置的一个或多个时隙格式。
示例的，若H的值是预定义好的，则无需基站通过第一配置信息再通知给终端设备。
其中通知终端设备可配置的一个或者多个时隙格式，有助于降低信令开销，示例的，假设时隙格式的类型总数为W种，以子载波间隔为例，若对于子载波间隔为15KHz时可配置的时隙格式可能仅为W种中的A种，其中A小于W，若基站在不通知终端设备可配置的一个或多个时隙格式、或者预定义可配置的一个或多个时隙格式时，15KH在对应的域的长度为
Figure PCTCN2018087106-appb-000001
当基站通知终端设备可配置的一个或多个时隙格式、或者预定义可配置的一个或多个时隙格式时，15KH在对应的域的长度为
Figure PCTCN2018087106-appb-000002
由于A小于W，因此降低了第一指示信息的信令开销。
此外，本申请实施例中还提供了一种第一指示信息的实现方式：
第一指示信息指示第一时隙格式组合方式，第一时隙组合方式为K种参数对应的时隙格式组合，其中K为M个CC对应的参数的种类数据。
示例的，以参数为子载波间隔为例，M个CC对应子载波的种类数为2，分别为子载波间隔15KHz和30KHz，若15KHz和30KHz分别对应的可能的时隙格式的组合方式为{时隙格式1、时隙格式2}、{时隙格式2、时隙格式3}和{时隙格式4和时隙格式5}，若M个CC中15KHz的CC的时隙格式为时隙格式4，30KHz的CC的时隙格式为时隙格式5，则第一指示信息指示第一时隙格式的组合方式为{时隙格式4和时隙格式5}，在本申请实施例中，分别对这三种组合方式进行编码，例如00指示时隙格式的组合方式为{时隙格式1、时隙格式2}，01指示时隙格式的组合方式为{时隙格式2、时隙格式3}，11指示时隙格式的组合方式为{时隙格式4、时隙格式5}，则第一指示信息为11，通过这种技术方案有助于进一步降低第一指示信息的信令开销。其中时隙格式的组合方式、以及时隙格式的组合方式的编码方式如00、01可以通过RRC信令或者MAC信令通知给终端设备。
其中需要说明的是，在上述两种第一指示信息的实现方式中，由于子载波间隔不同时，时隙的大小不同，例如子载波间隔为15KHz对应的时隙为子载波间隔为30KHz对应的时隙的 两倍，在这种情况下，若第一指示信息中指示时隙格式1和时隙格式2，其中时隙格式1为子载波间隔为15KHz对应的时隙格式，时隙格式2为子载波间隔为30KHz对应的时隙格式，假设CC1的子载波间隔为15KHz，CC2的子载波间隔为30KHz，则CC1在15KHz对应的时隙上的时隙格式为时隙格式1，而CC2在该15KHz对应的时隙所在的时间段内包括两个30KHz对应的时隙，则CC2在这两个30KHz对应的时隙上均为时隙格式2。
在本申请实施例中，为了避免上下行的相互干扰，M个CC中包括的各个CC的时隙格式中，处于相同时域位置上的传输方向上不同时出现上行和下行。
以图5中所示的时隙格式为例，对于时隙格式1的时域位置A上的传输方向为下行，时隙格式2在时域位置A上的传输方向为下行，时隙格式3在时域位置A上的传输方向为unknown，则时隙格式1、时隙格式2、时隙格式3在时域位置A上的传输方向未同时出现上行和下行，而时隙格式1在时域位置B上的传输方向为下行，时隙格式2在时域位置B上的传输方向为unknown，时隙格式3在时域位置B上的传输方向为上行，则时隙格式1在时域位置B上的传输方向与时隙格式3在时域位置B上的传输方向上同时出现了上行和下行，因此时隙格式1和时隙格式3不会同时出现在M个CC中包括的各个时隙格式中。而时隙格式2在时域位置B和时隙格式1在时域位置B未同时出现上行和下行、时隙格式2在时域位置B和时隙格式3在时域位置B上未同时出现上行和下行。
此外，当M个CC中包括的各个CC的时隙格式中，处于相同时域位置上的传输方向上不同时出现上行和下行时，本申请实施例中还提供了一种第一指示信息的实现方式：
具体的，假设子载波间隔为15KHz对应的时隙格式所有可能的情况为图1所示，若M为2，具体的为CC1和CC2，假设CC1的子载波间隔为15KHz，CC2的子载波间隔为30KHz，若CC1的时隙格式为如图1所示的时隙格式6，则在15KHz对应的时隙内CC2分别在第一个30KHz对应的时隙和第二30KHz对应的时隙内的时隙格式在满足处于相同时域位置上的传输方向上不同时出现上行和下行的条件下，存在如图6所示的可能的组合情况，当CC2在第一个30KHz对应的时隙和第二30KHz对应的时隙内的时隙格式为如图6所示的第(5)中组合时，则可以将第(5)中组合与时隙格式6组合编码通知给终端设备，也可以通过两个2域将CC1和CC2的时隙格式通知给终端设备，具体的，其中一个域指示时隙格式6，另外一个域指示CC2在第一个30KHz对应的时隙和第二30KHz对应的时隙内的时隙格式的组合方式。此外，在本申请实施例中还可以通过其它方式向终端设备指示配置给该终端设备的CC的时隙格式，对此本申请实施例不作限定。
本申请实施例中，基站向终端设备发送第一指示信息，可以通过下列方式实现：
基站在M个CC中的N个CC上发送第一指示信息，其中N为大于等于1的整数，且N小于等于M。
示例的，当N＝1时，基站可以在M个CC中一个CC上向终端设备发送第一指示信息，具体的，基站在该CC上的group common PDCCH上发送第一指示信息，还需要说明的是M个CC中一个CC可以预先定义，也可以预定义N＝1，然后由基站通知终端设备具体发送第一指示信息的是M个CC中的哪个CC，还可以由基站通知给终端设备N的取值以及具体发送第一指示信息的CC，示例的，基站向终端设备发送第二配置信息，其中第二配置信息包括M个CC中选择的CC和发送第一指示信息的CC的个数。由于在该技术方案中仅在一个CC上发送第一指示信息，因而有助于降低终端设备盲检的次数。
示例的，N还可以取值为大于1小于M的值，基站分别这N个CC中的每个CC上发送第一指示信息，通过这种方式与使用M个CC分别发送第一指示信息相比，在一定程度上降低了盲检的次数的同时，有助于提高了终端设备接收第一指示信息的可靠性。在这种情况下，为了使得终端设备能够确定基站是在哪些CC上发送第一指示信息的，其具体实现方式与N取值为1时类似，在此不再赘述。
示例的，N还可以取值为M，基站分别这M个CC中的每个CC上发送第一指示信息，这种情况下可以预定义或者通知的方式通知终端设备发送第一指示信息的CC的个数和这M个CC，通过这种方式，最大程度的提高了终端设备接收第一指示信息的可靠性。当N＝M时，在该情况下，其终端设备确定基站在哪些CC上发送第一指示信息的具体实现方式可以与N取值为1时类似，除此之外，当N＝M时，在预定义N＝M的情况下，第二配置信息中还可以不包括这M个CC，因为终端设备在确定N＝M后，即可确定在全部的CC上接收第一指示信息即可，而无需在另外进行指示。
此外，在本申请实施例中，当N取值大于1时，还可以N个CC中的部分CC上发送部分第一指示信息，由N个部分第一指示信息组成一个完整的第一指示信息，具体的，基站分别在N个CC上发送部分第一指示信息，由N个部分第一指示信息组成第一指示信息。示例的，假设N取值为2，分别为CC1和CC2，第一指示信息分为两部分，其中一部分在CC1上发送给终端设备，另一部分在CC2上发送给终端设备。在这种情况下，基站发送第一指示信息的CC和发送第一指示信息的CC个数可通过第二配置信息发送给终端设备。
基于同一构思，本申请实施例中还提供了一种网络设备，用于执行上述方法实施例中网络设备的动作或功能。
基于同一构思，本申请实施例中还提供了一种终端设备，用于执行上述方法实施例中的终端设备的动作或功能。

为了节省篇幅，装置部分的内容的具体实现方式可以参见方法实施例，重复之处不再赘述。
如图7a所示，本申请实施例的网络设备700，包括处理模块701和收发模块702，其中处理模块701用于生成第一指示信息，收发模块用于向终端设备发送第一指示信息，其中第一指示信息指示K个时隙格式，该K个时隙格式为配置给终端设备的M个CC的时隙格式，其中K个时隙格式中的至少一个时隙格式对应M个CC中的至少两个CC，该至少两个CC的配置参数中的至少一种参数相同，K为大于等于且小于等于M的整数，M为大于1的整数，配置参数包括子载波检核、循环前缀、带宽和频段中的至少一种参数。
在具体实现时，第一指示信息一种可能的设计为：第一指示信息包括H个域，H个域中的K个域分别指示K个时隙格式中的一个时隙格式，H为大于等于K的正整数。
为了便于终端设备能够准确读取第一指示信息，一种可能的设计为：收发模块702用于向终端设备发送第一配置信息后，在向终端设备发送第一指示信息，其中第一配置信息包括或者指示下列信息中的至少一种：
H的值、H个域中的每一个域对应的参数和可配置的一个或多个时隙格式。
在具体实现时，第一指示信息另一种可能的设计为：第一指示信息指示第一时隙格式组合方式，其中第一时隙格式组合方式为K种参数对应的时隙格式组合，其中K为M个CC 对应的参数的种类数。
在具体实现时，本申请实施例中收发模块702用于向终端设备发送第一指示信息的一种可能的设计为：收发模块702用于在M个CC中的N个CC上发送第一指示信息，N为大于等于1的整数，且N小于等于M。其中当N取值为1时，上述技术方案有助于减少终端设备的盲检次数，从而降低功耗。当N取值大于1小于M时，上述技术方案有助于在一定程度上减少终端设备的盲检次数的同时提高第一指示信息传输的可靠性；当N取值为M时，上述技术方案能够最大程度提高第一指示信息传输的可靠性。
需要说明的是，通常情况下收发模块702是在N个CC上的group common PDCCH上发送的。
