传输参考信号的方法、终端设备和网络设备 技术领域
本申请实施例涉及无线通信领域，并且更具体地，涉及一种传输参考信号的方法、终端设备和网络设备。
背景技术
目前在5G***，或称新无线***(New Radio，简称“NR”)中，多种业务之间可以动态共享资源，例如增强移动宽带(Enhanced Mobile Broad Band，简称“eMBB”)业务就可以与超高可靠与低时延通信(High Reliable and Low Latency Communications，简称“URLLC”)业务动态共享资源，即在某些物理资源块上进行数据传输的eMBB业务，在特定条件下，这些资源可以被优先的或重叠的被URLLC业务复用。对于这种复用方式，URLLC业务默认具有更高的占有eMBB资源的优先权。由于eMBB业务与URLLC业务调度处理时延不同，因此基站可能来不及在调度eMBB业务的下行控制信令中通知终端当前eMBB业务中是否***了URLLC，终端设备也无法正确对基站发送的信道进行解调等处理，这会严重影响终端设备对信道的接收处理，降低其接收性能。

方式4
该终端设备根据检测到的该目标参考信号的配置信息，以及参考信号配置信息与符号位置的对应关系，确定该第一时频资源中用于传输该目标信道的第一个符号。
例如，如图5所示的第一时频资源的示意图，假设第一时频资源在时域上包括7个符号，在频域上的带宽为f，且网络设备与终端设备之间约定了配置信息不同的6种参考信号，每种参考信号与时频资源的对应关系例如表三所示。表三中，第一种参考信号表示该目标信道自该第一时频资源中的第一个符号(符号1)开始进行资源映射；第二种参考信号表示该目标信道自第二个符号(符号2)开始进行资源映射；第三种参考信号表示该目标信道自第三个符号(符号3)开始进行资源映射；第四种参考信号表示该目标信道自第四个符号(符号4)开始进行资源映射；第五种参考信号表示该目标信道自第五个符号(符号5)开始进行资源映射；第六种参考信号表示该目标信道自第六个符号(符号6)开始进行资源映射。用于传输目标参考信号的特定时频资源为第七个符号。

可选地，该目标参考信号是通过M个天线端口进行传输的，且该目标信道是通过N个天线端口进行传输的，其中N大于或等于M。
可选地，若终端设备确定该第一时频资源中还包括用于传输其他信道或信号的时频资源，和/或预留资源，该方法还包括：若终端设备对该目标信道译码失败，则终端设备禁止储存该目标信道所承载的信息。
可选地，该方法还包括：若终端设备对该目标信道译码失败，则该终端设备储存该目标信道所承载的全部或部分有效信息，该有效信息包括该第一时频资源中用于传输该目标信道的时频资源的信息。
因此，本发明实施例中，终端设备通过对目标参考信号的检测结果的分析，可以合理的方式接收网络设备发送的目标信道，从而能够有效地对该目标信道进行解调等处理，增加了对目标信道的接收处理的成功率。

在320中当有其他的终端设备占用当前的该第一时频资源中的全部或部分时频资源进行信道或信号的传输时，网络设备会根据当前第一时频资源的资源占用情况，确定是否向终端设备发送目标参考信号和/或该目标参考信号的配置信息，以使得终端设备可以根据目标参考信号的检测结果，来获取第一时频资源的资源分配情况。网络设备根据该第一时频资源的分配情况，确定是否向终端设备发送目标参考信号和/或该目标参考信号的配置信息，例如可以通过以下四种方式来实现。
方式1
若该第一时频资源中不包括用于传输其他信道或信号的时频资源，和/或预留资源，则网络设备确定在该第一时频资源中的特定时频资源上向终端设备发送该目标参考信号；
若该第一时频资源中还包括用于传输其他信道或信号的时频资源，和/或预留资源，则网络设备确定在该第一时频资源中的特定时频资源上不向终端设备发送该目标参考信号。
方式2
若该第一时频资源中还包括用于传输其他信道或信号的时频资源，和/或预留资源，则网络设备确定该目标参考信号所使用的序列与前置参考信号的序列不相同，或者该目标参考信号所使用的覆盖码与该前置参考信号的覆 盖码不相同；
若该第一时频资源中不包括用于传输其他信道或信号的时频资源，和/或预留资源，则网络设备确定该目标参考信号所使用的序列与前置参考信号的序列相同，或者该目标参考信号所使用的覆盖码与该前置参考信号的覆盖码相同。
也就是说，网络设备可以通过不同配置的参考信号，来向终端设备指示当前该第一时频资源的资源分配情况，或者称为资源占用情况。
方式3
网络设备根据该第一时频资源中的用于传输其他信道或信号的时频资源，和/或预留资源，以及时频资源与参考信号配置的对应关系，确定该目标参考信号的配置信息。
其中，时频资源与参考信号配置之间的该对应关系例如可以参考前述对表一、表二、图4(a)和图4(b)的相关描述。为了简洁，这里不再赘述。
方式4
网络设备根据该第一时频资源中用于传输该目标信道的第一个符号，以及符号位置与参考信号配置信息的对应关系，确定该目标参考信号的配置信息。
其中，符号位置与参考信号配置信息之间的该对应关系例如可以参考前述对表三和图5的相关描述。为了简洁，这里不再赘述。
在该实施例中，网络设备根据第一时频资源的资源分配情况，确定是否向终端设备发送目标参考信号和/或目标参考信号的配置信息，从而能够灵活地向终端设备指示当前时频资源的资源分配情况。
终端设备通过目标参考信号的检测结果，能够获知当前用于接收目标信道的时频资源的资源分配情况例如该时频资源是否被其他信道或信号占用，或者被网络设备预留而不用于传输该目标信道，从而终端设备可以及时根据获取到的资源分配情况，接收网络设备给其发送的目标信道，并有效地对该目标信道进行解调等处理，增加了对目标信道的接收处理的成功率。
在330，若网络设备确定向终端设备发送该目标参考信号，则在第一时频资源中的特定时频资源上向该终端设备发送该目标参考信号。
可选地，该目标参考信号是通过M个天线端口进行传输的，且该目标信道是通过N个天线端口进行传输的，其中N大于或等于M。
也就是说，网络设备向目标参考信号映射在M个天线端口进行传输，并将目标信道映射在N个天线端口进行传输，且N大于或等于M。由于传输目标参考信号的天线端口少于传输目标信道的天线端口，目标参考信号不用分散至过多的天线端口进行传输，因而可以增强目标参考信号的发射功率。
在340中，网络设备在该第一时频资源上向终端设备发送目标信道，以及用于指示该第一时频资源的第一指示信息。
可选地，该方法还包括：网络设备向终端设备发送第二指示信息，该第二指示信息用于指示终端设备在该第一时频资源上检测该目标参考信号。
可选地，该方法还包括：网络设备向终端设备发送第三指示信息，该第三指示信息包括至少一个参考信号的配置信息，该至少一个参考信号的配置信息包括该目标参考信号的配置信息。
本发明实施例中，网络设备通过当前时频资源的资源分配情况，确定是否向终端设备发送目标参考信号和/或目标参考信号的配置信息，从而能够灵活地向终端设备指示当前时频资源的资源分配情况，以使得终端设备有效地对该目标信道进行解调等处理，增加了对目标信道的接收处理的成功率。
