一种信息传输方法及装置
本申请要求在2017年05月04日提交中国专利局、申请号为201710309717.8、发明名称为“一种信息传输方法及装置”的中国专利申请的优先权，以及本申请要求在2018年03月28日提交中国专利局、申请号为201810282225.9、发明名称为“一种信息传输方法及装置”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
本申请涉及通信技术领域，尤其涉及一种信息传输方法及装置。
背景技术
关于下一代移动通信技术，简单介绍如下：
移动互联网正在颠覆传统移动通信业务模式，为用户提供前所未有的使用体验，深刻影响着人们工作生活的方方面面。移动互联网将推动人类社会信息交互方式的进一步升级，为用户提供增强现实、虚拟现实、超高清(3D)视频、移动云等更加丰富的业务体验。移动互联网的进一步发展将带来未来移动流量超千倍增长，推动移动通信技术和产业的新一轮变革。而物联网则扩展了移动通信的服务范围，从人与人通信延伸到人与物、物与物智能互联，使移动通信技术渗透至更加广阔的行业和领域。未来，移动医疗、车联网、智能家居、工业控制、环境监测等将会推动物联网应用爆发式增长，数以千亿的设备将接入网络，实现真正的“万物互联”。同时，海量的设备连接和多样化的物联网业务也会给移动通信带来新的技术挑战。
随着新的业务需求的持续出现和丰富，对未来移动通信系统提出了更高的性能需求，例如更高的峰值速率、更好的用户体验速率、更小的时延、更高的可靠性、更高的频谱效率和更高的能耗效率等，并需要支持更多的用户接入以及使用各种业务类型。
LTE系统的物理下行控制信道(physical downlink control channel，PDCCH)用于承载调度信息以及其他控制信息。每个下行子帧的控制区域内可以有多个PDCCH。用户设备(User Equipment，UE)根据所要监听的下行控制信息(Downlink Control Information，DCI)格式(format)，来尝试解码搜索空间中的每一个PDCCH。
综上所述，在现有LTE系统中，UE根据期望得到的信息盲检自己的PDCCH。在未来的移动通信系统中，需要引入调度或者通知一组终端相关信息，但目前如何传输一组终端的信息并没有给出解决方案。

具体实施方式
本申请实施例提供了一种信息传输方法及装置，用以实现一组终端的信息的传输。
随着移动技术的发展，未来移动通信系统需要提供更低的网络时延并支持更丰富的业务类型。下行控制信道可能通知或者调度一个终端、基站内的所有终端、或者基站内的一组终端。下行控制信道的种类更加丰富，传输方式更加灵活。调度一个终端数据传输的下行控制信道可以在终端有数据进行传输时由基站发送，调度基站内所有终端的公共控制信道可以在每个时隙(slot)内的公共搜索空间传输。
本申请实施例中，通过组(group)公共(common)PDCCH携带一组终端的信息。具体该组终端的信息都包括哪些信息，本申请实施例中不做限定。考虑到group common PDCCH承载的信息并不需要同时传输，有些信息需要较高的传输频率进行传输，有些信息需要的传输频率较低。因此，通过group common PDCCH承载的信息可以按照信息类型使用不同的下行控制信息(Downlink Control Information，DCI)格式(format)进行传输。
本申请实施例中的group common PDCCH携带一组终端的信息，一组终端至少包含一个终端。
本申请实施例中的终端，也可以称为UE。UE可以是静止的或移动的。UE还可以称为移动站、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、手持设备、膝上型计算机、无绳电话、无线本地环路(WLL)站、平板电脑等。UE能够与宏eNB、微微eNB、毫微微eNB、中继站等网络侧设备进行通信。
本申请实施例中，group common PDCCH需要传输的一组终端的信息，例如：slot结构指示信息、PDCCH monitor相关信息、发送接收节点(transmission and receiving point， TRP)配置(configuration)信息等，可以采用不同的DCI format进行传输。
group common PDCCH承载的一组UE的信息所采用的DCI format至少有一种，例如两种，分别为DCI format X(或者称为第一DCI format)，和DCI format Y(或者称为至少一种除第一DCI格式之外的其他DCI format)。
可选地，可以采用不同的DCI format传输不同的信息。例如：
采用DCI format X发送的信息包括：时隙格式指示(slot format indication)，用以指示slot的结构，slot的结构例如用于指示有几个下行(DL)正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号，有几个上行(UL)OFDM符号，有几个保护间隔(Guard Period，GP)OFDM符号等。终端需要获知slot的结构才能确定哪些符号可以做上行传输，哪些符号可以做下行传输。
采用DCI format Y发送其他信息，其他信息例如：下行控制信道检测周期、子载波间隔(subcarrier space，SCS)信息(或者称为numerology信息)、发送接收节点(transmission and receiving point，TRP)信息等。
采用不同DCI format发送的信息，可以按照不同的规则进行划分，规则例如需要通过group common PDCCH承载的信息的发送周期、重要等级。具体可由协议规定，例如slot format information是必需的，因此是重要的，重要等级较高，可以采用一种DCI format进行信息传输，有些信息起到辅助传输的作用，因此可以认为重要性较低，可以采用另一种DCI format进行信息传输。
不同的DCI format可以在同一个slot内的group common PDCCH上传输。
采用不同的DCI format传输的信息的传输周期可以不同，例如采用DCI format X传输的信息需要每N个slot发送一次，采用DCI format Y传输的信息需要每2N个slot发送一次。
基站侧：
基站在group common PDCCH上发送一组终端的信息，具体地，可以采用下列两种方式进行发送：
方式一：基站和终端预先约定好不同的DCI format携带的信息内容，后续基站通过高层信令通知终端DCI format的相关信息，例如每一DCI format对应的信息发送周期，和/或，用于指示终端需要接收的DCI format类型的指示信息等，终端就可以根据这些相关信息，检测相应的DCI format，并获取相应信息。
其中，每一DCI format对应的信息发送周期可以不同，例如DCI format X对应的信息发送周期为N个slot，DCI format Y对应的信息发送周期为2N个slot，其中N为预设正整数。
基站通过高层信令通知终端用于指示终端需要接收的DCI format类型的指示信息。例 如，基站通知终端只需要检测接收DCI format X，或者基站通知终端只需要检测接收DCI format Y，或者基站通知终端需要检测接收DCI format X和DCI format Y。
方式二：基站在group common PDCCH上采用DCI format X和/或DCI format Y发送一组终端的信息。
综上，参见图1，在网络侧，例如在基站侧，本申请实施例提供的一种信息传输方法，包括：
S101、确定需要发送的一组终端的信息；
S102、通过组公共物理下行控制信道group common PDCCH发送组终端的信息。
可选地，采用至少一种下行控制信息DCI格式，通过group common PDCCH发送组终端的不同类型的信息。
可选地，组终端的信息至少包括：时隙格式指示；采用第一DCI格式发送时隙格式指示，采用至少一种除第一DCI格式之外的其他DCI格式发送时隙格式指示之外的信息。
其中，时隙格式指示之外的信息，例如下行控制信道检测周期、子载波间隔信息和发送接收节点信息。
可选地，采用不同的DCI格式发送的信息的发送周期不同。
可选地，通过group common PDCCH发送组终端的信息，具体包括：
通过高层信令发送至少一种下行控制信息DCI格式的相关信息；
或者，在group common PDCCH上采用至少一种DCI格式发送所述组终端的不同类型的信息。
可选地，至少一种DCI格式的相关信息包括：发送组终端的信息所采用的DCI格式对应的信息发送周期，和/或，终端需要检测的DCI格式的指示信息。
下面介绍一下与上述网络侧的信息传输方法相对应的终端侧的信息传输方法：
方式一：若基站和终端预先约定了采用不同的DCI format传输的信息内容，则终端按照高层信令通知的DCI format相关信息，接收group common PDCCH。
若基站通过高层信令通知终端不同DCI format的传输周期，例如DCI format X的传输周期为N个slot，DCI format Y的传输周期为2N。则终端每N个slot按照DCI format X检测接收group common PDCCH，每2N个slot按照DCI format Y检测接收group common PDCCH。
或者，若基站通过高层信令通知终端需要检测接收的DCI format类型，假设在group common PDCCH上传输的DCI format有两种，即DCI format X和DCI format Y。
例如，基站通过高层信令通知终端需要检测接收DCI format X，则终端按照DCI format X在每个group common PDCCH的资源集合内检测接收group common PDCCH。或者，基站通过高层信令通知终端需要检测接收DCI format Y，则终端按照DCI format Y在每个 group common PDCCH的资源集合内检测接收group common PDCCH。或者，若基站通过高层信令通知终端需要检测接收DCI format X和DCI format Y，则终端按照DCI format X以及DCI format Y在每个group common PDCCH的资源集合内检测接收group common PDCCH。
方式二，若基站直接通知终端所需要检测的DCI format，即基站通过显示方式在group common PDCCH上采用至少一种DCI format发送一组终端的信息，则终端在每个group common PDCCH的资源集合内按照DCI format X和/或DCI format Y检测接收group common PDCCH。
综上，在终端侧，参见图2，本申请实施例提供的一种信息传输方法，包括：
S201、检测组公共物理下行控制信道group common PDCCH；
S202、从group common PDCCH中获取一组终端的信息。
可选地，组终端的信息，是采用至少一种下行控制信息DCI格式，通过PDCCH发送的。
可选地，检测group common PDCCH，具体包括：
通过高层信令接收至少一种DCI格式的相关信息，按照至少一种DCI格式的相关信息，检测group common PDCCH；
或者，在每一group common PDCCH资源集合内，按照至少一种DCI格式，检测group common PDCCH。
可选地，至少一种DCI格式的相关信息包括：发送组终端的信息所采用的DCI格式对应的信息发送周期，和/或，终端需要检测的DCI格式的指示信息。
下面给出三个具体实施例的举例说明。
实施例1：参见图3，假设group common PDCCH上传输的信息由两种DCI format承载，例如DCI format X和DCI format Y。采用DCI format X传输的信息中至少包含slot的结构信息，采用DCI format Y传输的信息中包含其他信息，例如下行控制信道检测周期、numerology信息、TRP信息等。当然此处只是一个可能的例子，DCI format X和DCI format Y中包含的信息可以根据具体需要确定。假设UE1、UE2、UE3需要检测接收group common PDCCH1。假设基站通过高层信令，例如无线资源控制(Radio Resource Control，RRC)信号(signaling)通知终端，group common PDCCH的发送周期为N个slot，采用DCI format X发送的信息的发送周期为N个slot，采用DCI format Y发送的信息的发送周期为2N个slot。其中，N为大于或等于1的正整数。则终端每N个slot检测接收按照DCI format X发送的信息，并按照DCI format X发送的信息，例如slot的结构指示信息；终端每2N个slot检测接收按照DCI format Y发送的信息，并得到按照DCI format Y发送的信息，例如下行控制信道检测周期、numerology信息、TRP信息等。
实施例2：参见图4，假设group common PDCCH上传输的信息由两种DCI format承载，例如DCI format X和DCI format Y。按照DCI format X发送的信息中至少包含slot的结构信息，按照DCI format Y发送的信息中包含其他信息，例如下行控制信道检测周期、numerology信息、TRP信息等。当然此处只是一个可能的例子，按照DCI format X和DCI format Y发送的信息中包含的信息可以根据具体需要确定。假设UE1、UE2、UE3需要检测接收group common PDCCH1。假设基站通过高层信令，例如RRC signaling通知终端，group common PDCCH的发送周期为N个slot。同时，基站通过RRC signaling通知终端需要检测接收的DCI format。例如基站通过RRC signaling通知终端UE1/UE2/UE3需要检测的DCI format为DCI format X，则终端UE1/UE2/UE3在group common PDCCH的资源集合内只对按照DCI format X发送的信息进行接收；例如基站通过RRC signaling通知终端UE1/UE2/UE3需要检测的DCI format为DCI format Y，则终端UE1/UE2/UE3在group common PDCCH的资源集合内只对按照DCI format Y发送的信息进行接收；例如基站通过RRC signaling通知终端UE1/UE2/UE3需要检测的DCI format包括DCI format X和DCI format Y，则终端UE1/UE2/UE3在group common PDCCH的资源集合内对按照DCI format X和DCI format Y发送的信息进行接收。
实施例3：参见图5，假设group common PDCCH上传输的信息由两种DCI format承载，例如DCI format X和DCI format Y。按照DCI format X发送的信息中至少包含slot的结构信息，按照DCI format Y发送的信息中包含其他信息，例如下行控制信道检测周期、numerology信息、TRP信息等。当然此处只是一个可能的例子，按照DCI format X和DCI format Y发送的信息中包含的信息可以根据具体需要确定。假设UE1、UE2、UE3需要检测接收group common PDCCH1。假设基站通过高层信令，例如RRC signaling通知终端，group common PDCCH的发送周期为N个slot。基站在每个group common PDCCH的资源集合内，按照需要采用DCI format X和/或DCI format Y发送一组终端的信息。终端在每个group common PDCCH的资源集合内，需要按照DCI format X以及DCI format Y进行检测接收信息。例如基站在slot 0上的group common PDCCH资源集合内只按照DCI format X发送了一组终端的信息。则终端在该资源集合内检测DCI format X以及DCI format Y，最终只成功检测到了DCI format X，并获得了采用DCI format X发送的信息，例如slot的结构指示信息。再例如基站在slot N采用DCI format X以及DCI format Y发送了一组终端的信息。则终端在slot N的group common PDCCH资源集合内检测DCI format X以及DCI format Y，并检测到了DCI format X以及DCI format Y，以及成功获得了采用DCI format X以及DCI format Y发送的信息。
