Description

信息传输方法和设备
交叉引用
本申请要求在2020年04月21日提交中国专利局、申请号为202010319314.3、发明名称为“信息传输方法和设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信领域，尤其涉及一种信息传输方法和设备。
背景技术
第五代移动通信技术(5th-Generation，5G)新无线(New Radio，NR)作为5G领域的一个重要的应用场景，可采用共享频谱(例如，非授权频段)传输数据。非授权频段由多种技术(RATs)共用，因此，非授权频段在使用时必须符合一些规则，例如，说之前听(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等，以保证所有通信设备可以公平的使用该资源。
采用LBT机制可以解决一部分信道干扰问题，但由于LBT都是由发起节点(Initiating Device)执行的，不能解决响应节点(Responding Device)的隐藏节点干扰问题。如图1所示，gNB1在发送数据前执行LBT侦听到信道为空，因此gNB1向UE1发送数据，UE1接收数据。此时，UE2如果有数据需要发送，UE2执行LBT，因gNB1距离UE2较远，UE1处于接收状态，因此UE2侦听到信道为空，UE2开始发送数据。但是由于UE2和UE1距离较近，UE1可以接收到UE2发送的数据，此时UE2可以称作是UE1的隐藏节点，UE1接收gNB1的数据将会受到隐藏节点(UE2)的干扰。
发明内容
本发明实施例的目的是提供一种信息传输方法和设备，用以解决隐藏节点的干扰问题。
第一方面，提供了一种信息传输方法，所述方法由发起节点执行，所述方法包括：发送传输请求RTS信息，所述RTS信息包括响应节点的标识信息；接收来自所述响应节点的传输确认CTS信息。
第二方面，提供了一种信息传输方法，所述方法由响应节点执行，所述方法包括：接收来自发起节点的RTS信息；若所述RTS信息包括所述响应节点的标识信息，则发送CTS信息。
第三方面，提供了一种通信设备，该通信设备包括：发送模块，用于发送RTS信息，所述RTS信息包括响应节点的标识信息；接收模块，用于接收来自所述响应节点的CTS信息。
第四方面，提供了一种通信设备，该通信设备包括：接收模块，用于接收来自发起节点的RTS信息；发送模块，用于若所述RTS信息包括所述通信设备的标识信息，则发送CTS信息。
第五方面，提供了一种通信设备，该通信设备包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的指令或程序，所述指令或程序被所述处理器执行时实现如第一方面和第二方面中任意一个方面所述的信息传输方法。
第六方面，提供了一种可读存储介质，所述可读存储介质上存储指令或程序，所述指令或程序被处理器执行时实现如第一方面和第二方面中任意一个方面所述的信息传输方法。
在本发明实施例中，发起节点可以发送RTS信息，RTS信息包括响应节点的标识信息，并接收来自响应节点的CTS信息，发起节点和响应节点完成RTS/CTS握手，其他未完成RTS/CTS握手的节点，不会尝试进行传输，从而避免了响应节点周围的隐藏节点带来的干扰，提高通信效率。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。本说明书各个实施例中的“和/或”以及“/”可以表示前后两者的至少之一。
应理解，本发明实施例的技术方案可以应用于各种通信***，例如：长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、5G***，或者说新无线(New Radio，NR)***，或者为后续演进通信***。
在本发明实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)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，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本发明实施例中，网络设备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。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的***中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)，在5G***中称为下一代节点B(gNB)，或者后续演进通信***中的网络设备等等，然而用词并不构成限制。
如图2所示，本发明的一个实施例提供一种信息传输方法200，该方法可以由发起节点执行，换言之，该方法可以由安装在发起节点的软件或硬件来执行，该方法包括如下步骤：
S202：发送传输请求(Request To Send，RTS)信息，该RTS信息包括响应节点的标识信息。
本发明实施例中，发起节点可以是终端设备，也可以是网络设备。发起节点通过共享频谱发送数据之前可以发送RTS信息，该RTS信息中携带有网络分配向量(network allocation vector，NAV)值或者信道占用时间和响应节点的标识信息(例如响应节点的地址)。上述NAV值或者信道占用时间可以用于表示该发起节点要占用信道多长时间，这样，所有收到该RTS信息的其它节点(即响应节点之外的节点)在NAV或者信道占用时间内不会尝试进行数据传输。
上述共享频谱包括运营商内无线接入技术(RAT)间的共享频谱、运营商间的共享频谱，还可以是非授权频段。
S204：接收来自响应节点的传输确认(Confirm To Send，CTS)信息。
该实施例中，响应节点在接收到RTS信息后可以回复CTS信息，CTS 信息中携带有NAV值或者信道占用时间和发起节点的标识信息(例如，发起节点的地址)，这样，所有接收到CTS信息的其它节点(即发起节点之外的节点)在NAV或者信道占用时间内不会尝试进行传输，这样就避免了响应节点周围的隐藏节点造成的干扰问题。
本发明实施例提供的信息传输方法应用到图1所示的场景中时，其流程如下：gNB1发送RTS信息，该RTS信息包括NAV值或者信道占用时间和UE1的标识信息；UE1在接收到RTS信息后发送CTS信息，该CTS信息包括NAV值或者信道占用时间和gNB1的标识信息。此时，UE2也可以接收到UE1发送的CTS信息，这样，UE2在NAV或者信道占用时间内不会尝试进行传输，因此不会对UE1的接收造成干扰。
本发明实施例提供的信息传输方法，可以在NR中引入RTS/CTS的传输机制，发起节点可以发送RTS信息，RTS信息包括响应节点的标识信息，并接收来自响应节点的CTS信息，完成RTS/CTS握手，从而进行在共享频谱上的传输。而未完成RTS/CTS握手的节点不会在共享频谱上尝试进行传输，从而避免了响应节点周围的隐藏节点带来的干扰，提高通信效率。
为了实现RTS信息/CTS信息的传输，以下将分三个实施例对上述信息传输方法进行详细介绍。
实施例一
可选地，该实施例中的RTS信息/CTS信息可以承载于物理下行控制信道(Physical Downlink Control Channel，PDCCH)/物理上行控制信道(Physical Uplink Control Channel，PUCCH)中。
在一个例子一中，对于下行传输，也即在发起节点为网络设备，响应节点为终端设备的情况下，上述RTS信息通过第一PDCCH发送；CTS信息通过第一PUCCH接收。
在另一个例子二中，对于上行传输，也即在发起节点为终端设备，响应节点为网络设备的情况下，上述RTS信息通过第二PUCCH发送；CTS信息 通过第二PDCCH接收。
可以理解，上述例子一和例子二之间并无冲突的地方，也即上述例子一和例子二可以同时实施。
可选地，上述第一PDCCH可以通过第一无线网络临时标识(Radio Network Temporary Identifier，RNTI)加扰，该第一RNTI用于指示第一PDCCH承载的是RTS信息。由此，响应节点例如终端设备可以区分出收到的是否为RTS信息。
可选地，上述第二PDCCH可以通过第二RNTI加扰，该第二RNTI用于指示所述第二PDCCH承载的是CTS信息。由此，响应节点例如终端设备可以区分出收到的是否为CTS信息。
可选地，上述第一PDCCH和第二PDCCH均可以通过第三RNTI加扰，其中，该例子中的第一PDCCH和第二PDCCH是相同的PDCCH，第三RNTI用于指示该相同的PDCCH承载的是RTS信息或CTS信息(即与RTS信息和CTS信息之外的其它信息进行区分)，具体还可以通过相同的PDCCH承载的内容进一步区分是RTS信息或CTS信息。
例如，上述相同的PDCCH承载的第一下行控制信息(Downlink Control Information，DCI)携带有第一指示信息，该第一指示信息用于指示所述相同的PDCCH承载的是RTS信息还是CTS信息。
上述第一指示信息可以由第一DCI中新定义的指示域进行指示；或者，第一指示信息由第一DCI中多个域(例如多个不同的域)的特定取值或者特定取值的组合确定。
可选地，上述例子一和例子二中的第一PDCCH和第二PDCCH承载第一格式的DCI，该第一格式的DCI专门用于发送RTS信息和/或CTS信息。
该例子可以通过引入一种新的DCI格式(format)来实现，该DCI format(也即第一格式的DCI)专门用于承载RTS信息和/或CTS信息，终端设备或网络设备在收到该第一格式的DCI后可以根据承载的内容确定是RTS信息 还是CTS信息。
可选地，针对上述例子一和例子二中的第一PDCCH和第二PDCCH，可以通过现有DCI中显式地或者隐式地指示该DCI是否承载了RTS信息/CTS信息。例如，可以通过增加比特显式地指示该DCI是否承载了RTS信息/CTS信息；或者，隐式地通过DCI中不同域的特定取值或者特定取值的组合，指示该DCI是否承载了RTS信息/CTS信息。
具体例如，上述例子一中的第一PDCCH承载的第二DCI携带有第二指示信息，该第二指示信息用于指示第一PDCCH承载的是RTS信息；和/或，上述例子二中的第二PDCCH承载的第三DCI携带有第三指示信息，第三指示信息用于指示所述第二PDCCH承载的是CTS信息。
第二指示信息可以由第二DCI中新定义的指示域进行指示，或第二指示信息由第二DCI中多个域的特定取值或者特定取值的组合确定；和/或，第三指示信息由第三DCI中新定义的指示域进行指示，或第三指示信息由第三DCI中多个域的特定取值或者特定取值的组合确定。
可选地，针对上述例子一和例子二中的第一PUCCH和第二PUCCH，可以增加新的PUCCH格式，专门用于传输RTS信息/CTS信息，这样，网络设备(例如gNB)可以根据UCI承载的内容判断收到的是RTS信息还是CTS信息。此外，也可以在UCI中增加指示域，区分该UCI承载了RTS信息或者CTS信息。
进一步的，对于下行传输，CTS信息也可以在类似于PDCCH的信道中传输，也就是说RTS信息/CTS信息在相同类型的信道中传输，该处提到的相同类型的信道可以是采用相同信道格式。传输RTS信息/CTS信息的第一信道可以采用相同的RNTI加扰，通过第一信道承载的信息区分是RTS信息还是CTS信息；传输RTS信息/CTS信息的第一信道当然也可以采用不同的RNTI加扰，例如RTS-RNTI和CTS-RNTI进行区分。对于上行传输，CTS信息也可以在类似于PUCCH的信道中传输，也就是说RTS信息/CTS信息都 采用类似于PUCCH的信道(后续称第二信道)发送。通过第二信道承载的信息区分RTS信息/CTS信息。
具体地，在一个例子三中，对于下行传输，也即在发起节点为网络设备，响应节点为终端设备的情况下，上述RTS信息和CTS信息通过第一信道传输，该第一信道的信道格式可以和PDCCH的信道格式相同。
具体地，在一个例子四中，对于上行传输，也即在发起节点为终端设备，响应节点为网络设备的情况下，上述RTS信息和所述CTS信息通过第二信道传输，该第二信道的信道格式可以和PUCCH的信道格式相同。
可选地，在副链路(sidelink)场景中，例如，在发起节点和响应节点均为终端设备的情况下，上述RTS信息通过物理副链路控制信道(Physical Sidelink Control Channel，PSCCH)发送；CTS信息通过PSCCH接收，sidelink终端设备可以根据PSCCH承载的信息区分RTS信息/CTS信息。
实施例二
在实施例二中，RTS/CTS由前导码或序列(后续将前导码和前导序列统称为前导序列)和媒体访问控制(Media Access Control，MAC)控制单元(Control Element，CE)/MAC协议数据单元(Protocol Data Unit，PDU)组成，并按照后续列出的方法一至方法三的之一来标识RTS信息/CTS信息。
可选地，上述实施例200中的RTS信息通过第一消息发送，所述第一消息包括MAC CE或MAC PDU；和/或所述CTS信息通过第二消息接收，所述第二消息包括MAC CE或MAC PDU。
上述第一消息还包括第一前导序列，所述第一前导序列用于指示所述第一消息承载的是RTS信息；和/或所述第二消息还包括第二前导序列，所述第二前导序列用于指示所述第二消息承载的是CTS信息。
方法一
通过所述第一前导序列的格式确定所述第一消息承载的是RTS信息，所述第一前导序列的格式是预定义或者配置的；和/或通过所述第二前导序列的 格式确定所述第二消息承载的是CTS信息，所述第二前导序列的格式是预定义或者配置的。
该方法一可以通过预定义或者配置的前导码序列去标识MAC CE或者MAC PDU中承载的是RTS信息或者CTS信息。例如，前导码序列包括2个(或2个以上)正交或准正交的序列格式，其中1个(或1组)序列标识传输的MAC CE/MAC PDU为RTS信息，另外1个(或1组)序列标识传输的MAC CE/MAC PDU为CTS信息。
可选地，上述前导序列可重用NR中的主同步信号(PrimarySynchronization Signal，PSS)或者辅同步信号(SecondarySynchronizationSignal，SSS)序列，前导序列的传输位置可以在非同步栅格(non-sync raster)频域的一个或多个特定位置，以免干扰初始接入，和简化节点对RTS信息/CTS信息的检测。
方法二
通过所述第一前导序列所在的时频资源位置确定所述第一消息承载的是RTS信息；和/或通过所述第二前导序列所在的时频资源位置确定所述第二消息承载的是CTS信息。
该方法二可以通过预定义或者配置的前导序列所在的时域和/或频域位置来标识RTS信息/CTS信息。例如，前导序列可重用NR中的PSS或者SSS序列，在非同步栅格(non-sync raster)位置1的PSS指示MAC CE或者MAC PDU中承载的是RTS信息，non-sync raster位置2的PSS指示MAC CE或者MAC PDU中承载的是CTS信息。
方法三
通过所述第一消息的固定位置的负荷信息或者所述第一消息的解调参考信号DM-RS信息确定所述第一消息承载的是RTS信息；和/或通过所述第二消息的固定位置的负荷信息或者所述第二消息的DM-RS信息确定所述第二消息承载的是CTS信息。
该方法三可以通过MAC CE/MAC PDU的固定位置的负荷信息或者解调参考信号(Demodulation reference signals，DM-RS)信息标识MAC CE或者MAC PDU中承载的是RTS信息或者CTS信息。例如，MAC CE/MAC PDU重用物理广播信道(Physical Broadcasting Channel，PBCH)的结构，PBCH中的时域定时信息或者PBCHDM-RS信息标识RTS信息/CTS信息。
实施例三
上述实施例200中的RTS消息和CTS消息通过第三信道传输；其中，所述发起节点和所述响应节点能够检测到所述第三信道。
可选地，所述RTS信息的时域位置是预定义的；和/或所述CTS信息的时域位置是预定义的。
该实施例使得NR通信***有一个通用的RTS/CTS信道，***内的节点(网络设备和终端设备)都可以读取这个信道，从而解决隐藏节点问题。
为了使得网络设备和终端设备可以发送或者接收RTS信息/CTS信息，同时减少网络设备和终端设备的不必要的信号检测，***内的网络设备和终端设备可以同步，且发送RTS信息的时域位置可以是预设或者配置的。这样，网络设备和终端设备只要在预设或者配置的位置进行RTS信息的检测即可。当检测到RTS信息后，若网络设备或终端设备是RTS信息中指示的目标节点，则在一个预设的时延后发送CTS信息。若网络设备或终端设备没有检测到RTS信息，则在一个预设的时延后检测CTS信息。其中，其它检测到RTS信息或者CTS信息的网络设备和终端设备(非发送RTS信息/CTS信息的节点)，在RTS信息或者CTS信息指示的信道占用时间内不做传输。
