Description

一种信息传输的方法、设备及系统 技术领域
本发明涉及无线通信技术领域，尤其涉及一种信息传输的方法、设备及系统。
背景技术
随着通信技术的发展，第五代移动通信技术(5G，5th Generation)的研究也已经展开。5G的无线接入叫New Radio，简称NR。在目前采用的长期演进(LTE，Long Term Evolution)系统中，物理下行控制信道(PDCCH，Physical Downlink Control CHannel)在系统的控制区域内进行传输，系统的统控制区域占用整个系统带宽，占用的符号数为1-4个符号，具体符号数由物理控制格式指示信道(PCFICH，Physical Control Format Indicator Channel)通知终端。而在5G NR技术中，引入了控制资源集(CORESET，Control REsource SET)的概念，PDCCH能够在CORESET中传输，而CORESET在时域上占用1到3个符号，频域上不在占用整个系统带宽，而是一个可配置的带宽，因此，以时频资源块(RB，Resource Block)为例，用于表示CORESET占用资源元素(RE，Resource Element)的形状会比LTE系统中PDCCH占用的RE的形状复杂。CORSET占用的频域带宽资源以及时域符号数可以通过高层信令配置给终端。
每个终端的搜索空间在CORESET内定义，终端的PDCCH在搜索空间内的PDCCH候选candidates上传输。
为了能够提高资源的利用率，5G NR会将PDCCH未使用的资源共享给PDSCH，因此，终端需要知晓自身的物理下行共享信道(PDSCH，Physical Downlink Shared Channel)中是否存在其他用户的PDCCH，以作为终端进 行PDSCH速率匹配的依据。
发明内容

具体实施方式
下文结合附图对本发明实施例中的技术方案进行清楚、完整地描述。
参见图1，为示例性的且简化的通信系统结构，需要指出的是，图1所示的系统，仅仅是本发明实施例可能应用的一个系统示例，并且根据实际需要，本发明实施例的技术方案可以在各种系统中的任一种系统中实现。如图1所示，无线系统可以包括核心网侧、基站及用户设备(UE，User Equipment)。图1中，基站102可以经传输介质与一个或多个UE 104、106、108等通信，并且向UE 104、106、108等提供到核心网侧的接入点，因此，在LTE系统中，基站102可以是演进型节点B(eNB)，而在5G NR中，基站102可以是gNB。而UE104、106、108的示例则可以包括蜂窝电话、智能电话、会话发起协议(SIP)电话、膝上型计算机、个人数字助理(PDA)、卫星无线电、全球定位系统、多媒体设备、视频设备、数字音频播放器(例如，MP3播放器)、照相机、游戏控制台、平板计算机、或任何其它具有类似功能的设备。UE 104、106、108还可以被本领域技术人员称为终端、移动站、订户站、移动单元、订户单元、无线单元、远程单元、移动设备、无线设备、无线通信设备、远程设备、移动订户站、接入终端、移动终端、无线终端、远程终端、手持机、用户代理、移动客户端、客户端、或某种其它适当的术语。
参见图2所示的时频资源示意，由于在5G NR中PDCCH与PDSCH资源共享，基站在向UE发送的PDSCH中，可能会包含一个或多个其他终端的PDCCH，也可能仅包含UE自身的PDCCH，还有可能不包含PDCCH，如图2所示，以UE#1为例，UE#1的PDCCH位于CORSET3中。当网络调度UE#1的PDSCH位于Region 1且PDSCH起始符号为slot内的第一个符号时，PDSCH中包含其他UE的CORSET；当网络调度UE#1的PDSCH 位于Region 2，PDSCH中不包含任何UE的CORSET；当网络调度UE#1的PDSCH位于Region 3且起始符号大于CORSET 2占用的最后一个符号时，PDSCH中不包含其他UE的CORSET。
可以理解地，当UE#1的PDSCH中包含有其他UE的PDCCH时，会对UE#1进行PDSCH速率匹配造成影响，从而导致短暂时间段内的PDSCH数据包无法被正确解析。为了避免上述情况产生，提出了以下实施例。
实施例一
参见图3，其示出了本发明实施例提供的一种信息传输的方法，该方法可以应用于网络系统中的网络侧设备，例如5G NR中的gNB。本方法可以包括：
S301：生成针对目标终端的指示信息；
其中，所述指示信息用于指示向所述目标终端发送的PDSCH中非目标终端的PDCCH存在状态，和/或非目标终端的资源占用状态；
需要解释的是，在本实施例及后续实施例中，对于目标终端来说，在通信系统中，除目标终端以外的其他终端均可以称之为“非目标终端”，本实施例及后续实施例不再对非目标终端进行赘述。
S302：向所述目标终端发送所述指示信息。
可以理解地，目标终端接收到指示信息后，就可以按照指示信息获知发送给自身的PDSCH中是否包含有其他终端的PDCCH，终端就能够基于上述获知的内容进行PDSCH速率匹配，从而减少匹配错误，以避免由于匹配错误所造成的短暂时间段内的PDSCH数据包无法被正确解析的情况。
对于图3所示的技术方案，在第一种可能的实现方式中，所述指示信息包括PDCCH信令中的一个比特位，且所述比特位中的比特值用于表征向所述目标终端发送的PDSCH中是否存在非目标终端的PDCCH，和/或是否存在非目标终端的资源占用。
具体来说，该比特位可以通过比特值0和1来表征向所述目标终端发送的PDSCH中是否存在非目标终端的PDCCH，和/或是否存在非目标终端的资源占用。举例来说，当所述比特值为0时，表征向所述目标终端发送的PDSCH中不存在非目标终端的PDCCH，和/或不存在非目标终端的资源占用；当所述比特值为1时，表征向所述目标终端发送的PDSCH中存在非目标终端的PDCCH，和/或存在非目标终端的资源占用。可以理解地，在另一个例子中，也可以通过比特值为1来表征向所述目标终端发送的PDSCH中不存在非目标终端的PDCCH，和/或不存在非目标终端的资源占用；通过比特值为0来表征向所述目标终端发送的PDSCH中存在非目标终端的PDCCH，和/或存在非目标终端的资源占用。本实施例对此不做赘述，但为了便于技术方案的理解，本发明实施例采用上述两个例子中第一个举例内容所述的比特值及比特值的表征内容。
对于图3所示的技术方案，在第二种可能的实现方式中，所述指示信息包括PDCCH信令中的N个比特位，N大于1，其中，每个比特位与非目标终端对应，且每个比特位用于表征向所述目标终端发送的PDSCH中是否存在对应的非目标终端的PDCCH，和/或是否存在对应的非目标终端的资源占用。
具体来说，每个比特位均可以通过比特值0和1来表征向所述目标终端发送的PDSCH中是否存在对应的非目标终端的PDCCH，和/或是否存在对应的非目标终端的资源占用。例如，当比特位的比特值为0时，表征向所述目标终端发送的PDSCH中不存在该比特位对应的非目标终端的PDCCH，和/或不存在该比特位对应的非目标终端的资源占用；当比特位的比特值为1时，表征向所述目标终端发送的PDSCH中存在该比特位对应的非目标终端的PDCCH，和/或存在该比特位对应的非目标终端的资源占用。可以理解地，在另一个例子中，也可以通过比特值为1来表征向所述目标 终端发送的PDSCH中不存在该比特位对应的非目标终端的PDCCH，和/或不存在该比特位对应的非目标终端的资源占用；通过比特值为0来表征向所述目标终端发送的PDSCH中存在该比特位对应的非目标终端的PDCCH，和/或存在该比特位对应的非目标终端的资源占用。本实施例对此不做赘述，但为了便于技术方案的理解，本发明实施例采用上述两个例子中第一个举例内容所述的比特值及比特值的表征内容。
需要说明的是，上述两个可能的实现方式均是通过PDCCH信令来承载指示信息，具体来说，PDCCH信令可以包括下行控制信息(DCI，Downlink Control Information)，本实施例对此不做赘述。
此外，对于图3所示的技术方案，在第三种可能的实现方式中，所述指示信息包括无线资源控制(RRC，Radio Resource Control)信令中的一个比特位，且所述比特位中的比特值用于表征向所述目标终端发送的PDSCH中是否存在非目标终端的PDCCH，和/或是存在非目标终端的资源占用。
对于图3所示的技术方案，在第四种可能的实现方式中，所述指示信息包括RRC信令中的N个比特位，N大于1，其中，每个比特位与非目标终端对应，且每个比特位用于表征向目标终端发送的PDSCH中是否存在对应的非目标终端的PDCCH，和/或是存在对应的非目标终端的资源占用。
具体来说，在第三种及第四种实现方式中，RRC信令中比特位的比特值所表征的含义分别与第一种及第二种实现方式中所描述的PDCCH信令中比特位的比特值所表征的含义相同，此处不再赘述。
需要说明的是，由于指示信息通过RRC信令进行承载，因此，终端在接收到RRC信令指示变更的信息，例如承载有新的指示信息的RRC信令之前，目标终端均会按照现有RRC信令所承载的指示信息来确定向自身发送的PDSCH中是否存在非目标终端的PDCCH，和/或是否存在非目标终端的资源占用。
通过上述实施例，可以看出，网络侧设备，例如gNB可以通过PDCCH信令或RRC信令承载指示信息，以使得终端通过该指示信息获知向自身发送的PDSCH中是否存在其他终端的PDCCH，和/或是否存在其他终端的资源占用。从而可以基于指示信息所获知的内容进行PDSCH速率匹配，以避免由于匹配错误所造成的短暂时间段内的PDSCH数据包无法被正确解析的情况。
实施例二
基于前述实施例相同的发明构思，参见图4，其示出了本发明实施例提供的一种信息传输的方法，该方法可以应用于网络系统中的终端。本方法可以包括：
S401：终端接收指示信息；
其中，所述指示信息用于指示向所述终端发送的PDSCH中其他终端的PDCCH存在状态，和/或其他终端的资源占用状态；
S402：终端根据指示信息对向所述终端发送的PDSCH进行速率匹配。
可以理解地，当终端通过指示信息获知向所述终端发送的PDSCH中其他终端的PDCCH存在状态，和/或其他终端的资源占用状态之后，就可以基于上述获知的内容进行PDSCH速率匹配，从而减少匹配错误的发生，避免了由于匹配错误所造成的短暂时间段内的PDSCH数据包无法被正确解析的情况。
对于图4所示的技术方案，在第一种可能的实现方式中，所述指示信息包括PDCCH信令中的一个比特位，且所述比特位中的比特值用于表征向所述终端发送的PDSCH中是否存在其他终端的PDCCH，和/或是否存在其他终端的资源占用。
具体来说，当所述比特值为0时，表征向所述终端发送的PDSCH中不存在其他终端的PDCCH，和/或不存在其他终端的资源占用；当所述比特值 为1时，表征向所述终端发送的PDSCH中存在其他终端的PDCCH，和/或存在其他终端的资源占用。可以理解地，在另一个例子中，也可以通过比特值为1来表征向所述目标终端发送的PDSCH中不存在非目标终端的PDCCH，和/或不存在非目标终端的资源占用；通过比特值为0来表征向所述目标终端发送的PDSCH中存在非目标终端的PDCCH，和/或存在非目标终端的资源占用。本实施例对此不做赘述，但为了便于技术方案的理解，本发明实施例采用上述两个例子中第一个举例内容所述的比特值及比特值的表征内容。
对于图4所示的技术方案，在第二种可能的实现方式中，所述指示信息包括PDCCH信令中的N个比特位，N大于1，其中，每个比特位与其他终端对应，且每个比特位用于表征向所述终端发送的PDSCH中是否存在对应的其他终端的PDCCH，和/或是存在对应的其他终端的资源占用。
具体来说，每个比特位均可以通过比特值0和1来表征向所述终端发送的PDSCH中是否存在对应的其他终端的PDCCH，和/或是否存在对应的其他终端的资源占用。例如，当比特位的比特值为0时，表征向所述终端发送的PDSCH中不存在该比特位对应的其他终端的PDCCH，和/或不存在该比特位对应的其他终端的资源占用；当比特位的比特值为1时，表征向所述终端发送的PDSCH中存在该比特位对应的其他终端的PDCCH，和/或存在该比特位对应的其他终端的资源占用。可以理解地，在另一个例子中，也可以通过比特值为1来表征向所述目标终端发送的PDSCH中不存在该比特位对应的非目标终端的PDCCH，和/或不存在该比特位对应的非目标终端的资源占用；通过比特值为0来表征向所述目标终端发送的PDSCH中存在该比特位对应的非目标终端的PDCCH，和/或存在该比特位对应的非目标终端的资源占用。本实施例对此不做赘述，但为了便于技术方案的理解，本发明实施例采用上述两个例子中第一个举例内容所述的比特值及比特值 的表征内容。
需要说明的是，上述两个可能的实现方式均是通过PDCCH信令来承载指示信息，具体来说，PDCCH信令可以是下行控制信息(DCI，Downlink Control Information)，本实施例对此不做赘述。
此外，对于图4所示的技术方案，在第三种可能的实现方式中，所述指示信息包括无线资源控制(RRC，Radio Resource Control)信令中的一个比特位，且所述比特位中的比特值用于表征向所述终端发送的PDSCH中是否存在其他终端的PDCCH，和/或是否存在其他终端的资源占用。
对于图4所示的技术方案，在第四种可能的实现方式中，所述指示信息包括RRC信令中的N个比特位，N大于1，其中，每个比特位与其他终端对应，且每个比特位用于表征向所述终端发送的PDSCH中是否存在对应的其他终端的PDCCH，和/或是否存在对应的其他终端的资源占用。
具体来说，在第三种及第四种实现方式中，RRC信令中比特位的比特值所表征的含义分别与第一种及第二种实现方式中所描述的PDCCH信令中比特位的比特值所表征的含义相同，此处不再赘述。
上述四个实现方式介绍了通过两种信令承载指示信息的具体方案，基于上述四种实现方式中比特位的数量不同，S402的实现过程也相应不同。可以包括以下两种实现过程。
实现过程一
当所述指示信息包括PDCCH信令或RRC信令中的一个比特位时，终端根据指示信息对向所述终端发送的PDSCH进行速率匹配，可以包括：
当所述比特位的比特值为0时，终端根据预设的PDSCH时频资源与用于调度PDSCH的PDCCH时频资源之间的对应关系确定向所述终端发送的PDSCH中是否包含用于调度所述PDSCH的PDCCH；
若所述向所述终端发送的PDSCH中包含调度所述PDSCH的PDCCH， 则终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除后，再进行速率匹配；
若所述向所述终端发送的PDSCH中没有包含调度所述PDSCH的PDCCH，则终端直接将所述向所述终端发送的PDSCH进行速率匹配；
当所述比特位的比特值为1时，所述终端将其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除后，再进行速率匹配。
在一种实现方式中，终端将其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除后，还可以包括对终端自身PDCCH所占用的资源从所述向所述终端发送的PDSCH去除，因此，还可以包括：
终端根据预设的PDSCH时频资源与用于调度PDSCH的PDCCH时频资源之间的对应关系确定向所述终端发送的PDSCH中是否包含用于调度所述PDSCH的PDCCH；
若所述向所述终端发送的PDSCH中包含调度所述PDSCH的PDCCH，则终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除；
若所述向所述终端发送的PDSCH中没有包含调度所述PDSCH的PDCCH，则终端直接将所述向所述终端发送的PDSCH进行速率匹配。
具体来说，首先，终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除，可以包括：
终端按照预设的去除策略将用于调度所述PDSCH的PDCCH所对应的CORESET从所述向所述终端发送的PDSCH去除，或者将用于调度所述PDSCH的PDCCH所占用的RE从所述向所述终端发送的PDSCH去除。需要理解的是，通常PDCCH所对应的CORESET占用的资源要大于PDCCH所占用的RE，因此，终端可以通过预先与网络侧约定或接收网络侧通知信息来获知所述去除策略。
其次，终端将其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除，可以包括：
所述终端将其他终端的CORESET所占用的资源从所述向所述终端发送的PDSCH去除。需要说明的是，终端也可以通过网络侧预先发送的配置信息来获知其他终端的CORESET信息，也就能够预先获知其他终端的CORESET所占用的资源。
实现过程二
当所述指示信息包括PDCCH信令或RRC信令中的N个比特位时，根据指示信息对向所述终端发送的PDSCH进行速率匹配，可以包括：
终端遍历每个比特位的比特值；
当所有比特位的比特值为0时，终端根据预设的PDSCH时频资源与用于调度PDSCH的PDCCH时频资源之间的对应关系确定向所述终端发送的PDSCH中是否包含用于调度所述PDSCH的PDCCH；
若所述向所述终端发送的PDSCH中包含调度所述PDSCH的PDCCH，则终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除后，再进行速率匹配；
若所述向所述终端发送的PDSCH中没有包含调度所述PDSCH的PDCCH，则终端直接将所述向所述终端发送的PDSCH进行速率匹配；
当所有比特位中至少一个比特位的比特值为1时，所述终端将所述比特值为1的比特位对应其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除后，再进行速率匹配。
在一种实现方式中，终端将所述比特值为1的比特位对应其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除后，还可以包括对终端自身PDCCH所占用的资源从所述向所述终端发送的PDSCH去除，因此，还可以包括：
终端根据预设的PDSCH时频资源与用于调度PDSCH的PDCCH时频资源之间的对应关系确定向所述终端发送的PDSCH中是否包含用于调度所述PDSCH的PDCCH；
若所述向所述终端发送的PDSCH中包含调度所述PDSCH的PDCCH，则终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除；
若所述向所述终端发送的PDSCH中没有包含调度所述PDSCH的PDCCH，则终端直接将所述向所述终端发送的PDSCH进行速率匹配。
需要说明的是，终端将所述比特值为1的比特位对应其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除，可以包括：
所述终端将所述比特值为1的比特位对应其他终端的CORESET所占用的资源从所述向所述终端发送的PDSCH去除。
可以理解地，当终端在对向所述终端发送的PDSCH进行速率匹配之前通过上述两种实现过程将其他终端的PDCCH所占用的资源从向所述终端发送的PDSCH中进行去除。从而减少匹配错误的发生，避免了由于匹配错误所造成的短暂时间段内的PDSCH数据包无法被正确解析的情况。
实施例三
以下通过具体示例对上述实施例的技术方案进行详细说明。
具体示例一
在本具体示例中，指示信息仅包含1个比特位，因此，该比特位就表征向终端发送的PDSCH中是否包括其他终端的PDCCH。参见图5，本具体示例的流程如下：
S501：终端获取其他终端的PDCCH所占用的资源；
具体地，终端可以通过网络的预先配置来说只其他终端的PDCCH所占用的资源，具体可以是其他终端的CORESET占用的资源；
S502：基站在PDCCH信令或RRC信令中设置一个比特位，并对该比特位进行赋值；
举例来说，比特位中的比特值用于表征向所述终端发送的PDSCH中是否存在其他终端的PDCCH，和/或是否存在其他终端的资源占用。具体来说，当所述比特值为0时，表征向所述终端发送的PDSCH中不存在其他终端的PDCCH，和/或不存在其他终端的资源占用；当所述比特值为1时，表征向所述终端发送的PDSCH中存在其他终端的PDCCH，和/或存在其他终端的资源占用。
S503：基站将PDCCH信令或RRC信令发送至终端；
S504：终端通过解析PDCCH信令或RRC信令获取该比特位的比特值；
S504：终端判断比特值是否为1；若是，则转至S505；若否，则转至S506；
S505：终端将其他终端的PDCCH所占用的资源从向所述终端发送的PDSCH去除后，再进行速率匹配。
S506：终端根据预设的PDSCH时频资源与用于调度PDSCH的PDCCH时频资源之间的对应关系确定向所述终端发送的PDSCH中是否包含用于调度所述PDSCH的PDCCH；若是，则转至S507；否则转至S508；
S507：终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除后，再进行速率匹配；
S508：终端直接将所述向所述终端发送的PDSCH进行速率匹配。
需要理解地，S506至S508是针对终端自身的PDCCH所占用的资源从向所述终端发送的PDSCH中进行去除，因此在具体实现过程时，根据S505的步骤将其他终端的PDCCH所占资源从向所述终端发送的PDSCH中进行去除之后，还可以接着按照S506至S508的步骤针对终端自身的PDCCH所占用的资源从向所述终端发送的PDSCH中进行去除，最后在进行速率匹 配。
从本具体示例可以看出，终端通过接收到的指示信息获知向自身发送的PDSCH是否包含有其他终端PDCCH，将其他终端的PDCCH从向自身发送的PDSCH中去除后再进行速率匹配，从而能够减少匹配错误的发生，避免了由于匹配错误所造成的短暂时间段内的PDSCH数据包无法被正确解析的情况。
具体示例二
在本具体示例中，指示信息仅包含N个比特位，N大于1，因此，每个比特位均对应一个除终端以外的其他终端，参见图6，本具体示例的流程如下：
S601：终端根据预先接收的配置信息获取N个比特位对应的N个其他终端的PDCCH所占资源；
S602：基站在PDCCH信令或RRC信令中设置N个比特位，并根据向所述终端发送的PDSCH中其他终端的PDCCH存在状态，和/或其他终端的资源占用状态对N个比特位进行赋值；
具体来说，每个比特位均与其他终端对应，且每个比特位用于表征向所述终端发送的PDSCH中是否存在对应的其他终端的PDCCH，和/或是否存在对应的其他终端的资源占用。比如，当比特位的比特值为0时，表征向所述终端发送的PDSCH中不存在该比特位对应的其他终端的PDCCH，和/或不存在该比特位对应的其他终端的资源占用；当比特位的比特值为0时，表征向所述终端发送的PDSCH中存在该比特位对应的其他终端的PDCCH，和/或存在该比特位对应的其他终端的资源占用。
举例来说，当基站所辖的终端数量为4时，那么对于本具体示例中的终端X来说，其他终端的数量N就为3，基站在在PDCCH信令或RRC信令中设置3个比特位，其他终端依次以A、B、C进行表示，分别与3个比 特位按照顺序进行对应，那么可以得知，当3个比特位为“000”时，则表示其他终端A、B、C的PDCCH均没有占用终端X的PDSCH。当3个比特位为“100”，则表示A的PDCCH占用了终端X的PDSCH，而B、C的PDCCH均没有占用终端X的PDSCH，以此类推，本具体事例不再赘述。
S603：基站将PDCCH信令或RRC信令发送至终端；
S604：终端通过解析PDCCH信令或RRC信令获取N个比特位及比特值；
S605：终端遍历N个比特位，判断所有比特位是否都为0；若是，则转至S606至S608；若否，则转至S609
S606：终端根据预设的PDSCH时频资源与用于调度PDSCH的PDCCH时频资源之间的对应关系确定向所述终端发送的PDSCH中是否包含用于调度所述PDSCH的PDCCH；若是，则转至S607；否则转至S608；
S607：终端将用于调度所述PDSCH的PDCCH从所述向所述终端发送的PDSCH去除后，再进行速率匹配；
S608：终端直接将所述向所述终端发送的PDSCH进行速率匹配；
S609：终端将比特值为1的比特位对应其他终端的PDCCH所占用的资源从所述向所述终端发送的PDSCH去除后，再进行速率匹配。
需要理解地，S606至S608是针对终端自身的PDCCH所占用的资源从向所述终端发送的PDSCH中进行去除，因此在具体实现过程时，根据S609的步骤将其他终端的PDCCH所占资源从向所述终端发送的PDSCH中进行去除之后，还可以接着按照S606至S608的步骤针对终端自身的PDCCH所占用的资源从向所述终端发送的PDSCH中进行去除，最后在进行速率匹配。
从本具体示例可以看出，终端通过接收到的指示信息获知向自身发送的PDSCH是否包含有其他终端PDCCH，以及具体对应的其他终端，将对 应个其他终端的PDCCH从向自身发送的PDSCH中去除后再进行速率匹配，从而能够减少匹配错误的发生，避免了由于匹配错误所造成的短暂时间段内的PDSCH数据包无法被正确解析的情况。
