Description

一种上行信号的传输方法及终端设备、网络设备 技术领域
本申请实施例涉及通信技术领域，具体涉及一种上行信号的传输方法及终端设备、网络设备。
背景技术
在新无线(New Radio，NR)系统例如5G应用中，可以采用免授权(unlicensed)频谱，即在免授权频谱的信道上使用NR技术进行通信。为了让使用免授权频谱进行无线通信的各个无线通信系统在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在欧洲地区，通信设备遵循“先听后说”(listen-before-talk，LBT)原则，即通信设备在免授权频谱的信道上进行信号发送之前，需要先在免授权频谱的信道上进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果信道侦听结果为信道繁忙，该通信设备则不能进行信号发送。
然而，在NR-U(New Radio-Unlicensed)系统中，当终端设备进行配置上行授权(Configure Grant Uplink)的数据传输时，终端设备用于进行上行传输的时域资源是网络设备提前配置的，其中，终端设备在该提前配置的时域资源上可以传输上行数据和用于解调该上行数据的解调信号。但在一些情况下，例如，为了留出LBT的检测间隙以便该终端设备与其他通信设备在免授权频谱上进行复用传输，该终端设备不能在网络设备预先配置的时域资源中的部分资源上进行传输。
因此，亟需提供一种免授权频谱上的上行信号传输方法，用以实现用于解调上行数据的解调信号在免授权频谱上的正确传输。
发明内容

其中，所述第一符号包括所述第一时间单元内的第一个符号和所述第一时间单元内的最后一个符号中的至少一个符号。
第二方面，提供了另一种上行信号的传输方法，包括：

其中，所述第一符号包括所述第一时间单元内的第一个符号和所述第一时间单元内的最后一个符号中的至少一个符号。

具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该芯片的设备执行如上述第一方面至上述第二方面中的任一方面或其各实现方式中的方法。
第七方面，提供了一种计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述第一方面至上述第二方面中的任一方面或其各实现方式中的方法。

第九方面，提供了一种计算机程序，当其在计算机上运行时，使得计算机执行上述第一方面至上述第二方面中的任一方面或其各实现方式中的方法。
通过上述技术方案，通过终端设备在免授权频谱上的第一时间单元上向网络设备发送第一解调信号和第一传输块速率匹配得到的上行数据，其中，所述第一解调信号用于解调所述上行数据，所述第一解调信号占用的符号不包括第一符号，其中，所述第一符号包括所述第一时间单元内的第一个符号和所述第一时间单元内的最后一个符号中的至少一个符号，能够避免用于解调上行数据的解调信号不占用终端设备在网络设备预先配置的时域资源中可能不能进行传输的部分资源，从而实现了用于解调上行数据的解调信号在免授权频谱上的正确传输。

图2A为本申请实施例提供的一种上行信号的传输方法200的示意性流程图，如图2A所示。
210、终端设备在免授权频谱上的第一时间单元上向网络设备发送第一解调信号和第一传输块速率匹配得到的上行数据，其中，所述第一解调信号用于解调所述上行数据，所述第一解调信号占用的符号不包括第一符号。
可以理解的是，所述第一时间单元，可以为一个时隙，例如，第一时间单元可以包括14个符号；或者还可以为子时隙(其中，一个子时隙包括N个符号，N为大于等于2且小于14的整数)，例如，第一时间单元可以包括7个符号；或者还可以为多个时隙的集合，例如，第一时间单元可以包括12个时隙的集合；或者还可以为多个子时隙的集合，例如，第一时间单元可以包括2个子时隙的集合，其中一个子时隙包括4个符号，另一个子时隙包括7个符号，等等。本实施例对此不进行特别限定。
其中，所述第一符号可以包括但不限于所述第一时间单元内的第一个符号和所述第一时间单元内的最后一个符号中的至少一个符号，本实施例对此不进行特别限定。
以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，所述第一符号则可以包括符号0和符号13中的至少一个符号。
可选地，在本实施例的一个可能的实现方式中，所述终端设备还可以进一步在所述第一时间单元上向所述网络设备还发送第二解调信号，其中，所述第二解调信号用于解调所述上行数据，所述第二解调信号占用的符号不包括所述第一符号。
在一个具体的实现过程中，所述第一解调信号可以包括解调参考信号(Demodulation Reference Signal，DMRS)，所述第二解调信号可以包括上行控制信息(Uplink Control Information，UCI)，或者所述第一解调信号可以包括UCI，所述第二解调信号可以包括DMRS，本实施例对此不进行特别限定。
在另一个具体的实现过程中，所述第二解调信号占用的符号还可以进一步不包括所述第一解调信号占用的符号。
应理解，在本申请实施例中，解调信号占用某符号，可以指该解调信号通过该符号上的全部资源或部分资源进行传输，本实施例对此不进行特别限定。
在另一个具体的实现过程中，所述第二解调信号占用的符号还可以进一步包括所述第一解调信号占用的符号，即，第一解调信号通过该符号上的部分资源进行传输，第二解调信号也通过该符号上的部分资源进行传输。
在另一个具体的实现过程中，所述第二解调信号占用的符号具体可以是根据所述第一解调信号占用的符号确定的。
例如，所述第二解调信号占用的符号可以包括所述第一解调信号占用的符号后面的第一个符号。以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1，第二解调信号占用的符号则可以包括符号2，如图2B所示。
或者，再例如，所述第二解调信号占用的符号可以包括所述第一解调信号占用的符号前面的最后一个符号。以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号3，第二解调信号占用的符号则可以包括符号2，如图2C所示。
或者，再例如，所述第二解调信号占用多个符号，所述第二解调信号占用的符号中的第一个符号为所述第一解调信号占用的符号后面的第一个符号。以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1，第二解调信号占用的符号中的第一个符号则可以为符号2。
或者，再例如，所述第一解调信号占用多个符号，所述第二解调信号占用的符号包括所述第一解调信号占用的第一个符号后面的第一个符号。以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1和符号8，第二解调信号占用的符号则可以包括符号2。
在一些情况下，例如，为了留出LBT的检测间隙以便该终端设备与其他通信设备在免授权频谱上进行复用传输，该终端设备不能在网络设备预先配置的时域资源中的部分资源上进行传输，例如，一个 时隙的第一个符号即符号0、最后一个符号即符号13等特殊位置符号，因此，在免授权频谱上，采用本实施例中所提供的第一解调信号、第二解调信号和上行数据的映射配置，能够避免用于解调上行数据的解调信号不占用终端设备在网络设备预先配置的时域资源中可能不能进行传输的部分资源，从而实现了用于解调上行数据的解调信号在免授权频谱上的正确传输。
以第一解调信号为DMRS，第二解调信号为UCI为例，假设DMRS占用的符号为符号1，UCI占用的符号为符号2，上行数据占用的资源包括一个时隙中没有被DMRS和UCI占用的其他资源。
可以根据上述原则，连续3个时隙传输进行Configure Grant Uplink的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输且每个时隙都传输一个完整时隙的映射方式可以如图2D所示。
还可以根据上述原则，连续3个时隙传输进行Configure Grant Uplink的PUSCH传输且该连续3个时隙中可能有部分符号不传输(例如，第一个时隙不传输符号0、第二个时隙不传输符号0和符号13)的映射方式可以如图2E所示，图中的X表示不传输。
如图2D和2E所示，在上述两种上行传输的过程中，DMRS和UCI的位置都位于不能被丢弃的符号上，从而保证了用于解调上行数据的解调信号在免授权频谱上的正确传输。
在另一个具体的实现过程中，所述第一解调信号占用的符号可以是标准规范规定的。
例如，所述第一解调信号占用的符号具体可以包括所述第一时间单元内的第二个符号。
在另一个具体的实现过程中，所述第一解调信号占用的符号可以是所述网络设备通过指示信息发送给所述终端设备的。
其中，所述指示信息可以为物理层信令，或者还可以为媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)信令，或者还可以为无线资源控制无线资源控制(Radio Resource Control，RRC)信令，本实施例对此不进行特别限定。
当指示信息为物理层信令时，所述指示信息可以通过物理层信令显示指示或隐式指示。
例如，所述网络设备通过下行控制信息(Downlink control information，DCI)指示所述终端设备所述第一解调信号占用的符号(或指示所述第一解调信号占用的第一个符号，或指示所述第一解调信号占用的最后一个符号)。其中，所述DCI还包括所述网络设备指示所述终端设备可以使用或禁止使用所述第一时间单元的信息。
或者，再例如，DCI格式1对应一种第一解调信号占用的符号(例如第一解调信号占用符号3)，DCI格式2对应另一种第一解调信号占用的符号(例如第一解调信号占用符号5)。当终端设备收到DCI格式1时，可以确定第一解调信号占用的符号包括符号3；当终端设备收到DCI格式2时，可以确定第一解调信号占用的符号包括符号5。
可以理解的是，所述指示信息还可以是RRC信令和物理层信令的结合。例如，网络设备配置至少两种第一解调信号占用的符号的配置，并通过DCI指示终端设备在一次上行传输中应该使用该至少两种配置中的哪一种。
可选地，在本申请实施例中，UCI可以包括用于解调所述上行数据的控制信息，因此，该UCI也可以认为是解调所述上行数据必需的解调信号。
其中，所述UCI可以包括但不限于以下信息中的至少一种：
所述第一传输块对应的混合自动请求重传(Hybrid Automatic Repeat reQuest，HARQ)标识、所述终端设备的标识、所述第一时间单元的起始符号、所述第一时间单元的结束符号以及所述第一传输块包括的码块组(Code Block Group，CBG)指示。
例如，所述上行数据在所述第一时间单元上映射的起始位置可以包括所述第一时间单元内的第一个符号。这种方式，上行数据从所述第一时间单元内的第一个符号开始映射，到第一时间单元内的最后一个符号结束映射，以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1，第二解调信号占用的符号则可以包括符号2，那么，在符号0、符号3～符号13这些符号上，上行数据则可以从符号0开始映射，到符号13结束映射，如图2F所示，其映射方式简单。
或者，再例如，所述上行数据在所述第一时间单元上映射的起始位置可以包括所述第一时间单元内除第一个符号外的一个符号，其中，所述第一时间单元内的第一个符号不映射上行数据。这种方式，上行数据从所述第一时间单元内除第一个符号外的一个符号开始映射，到第一时间单元内的最后一个符号结束映射，以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1，第二解调信号占用的符号则可以包括符号2，那么，在符号0、符号3～符号13这些符号上，上行数据则可以从符号3开始映射，到符号13结束映射，其中，符号0不映射上行数据，如图2G所示。
或者，再例如，所述上行数据在所述第一时间单元上映射的结束位置可以包括所述第一时间单元内的第一个符号。这种方式，上行数据从所述第一时间单元内其他符号开始映射，到最后一个符号之后再返回到第一个符号结束映射，以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1，第二解调信号占用的符号则可以包括符号2，那么，在符号0、符号3～符号13这些符号上，上行数据则可以从符号3开始映射，到符号13之后再返回到符号0结束映射，如图2H所示，其映射方式较为复杂，但可以保证上行数据的系统信息的传输。
本实施例中，通过终端设备在免授权频谱上的第一时间单元上向网络设备发送第一解调信号和第一传输块速率匹配得到的上行数据，其中，所述第一解调信号用于解调所述上行数据，所述第一解调信号占用的符号不包括第一符号，其中，所述第一符号包括所述第一时间单元内的第一个符号和所述第一时间单元内的最后一个符号中的至少一个符号，能够避免用于解调上行数据的解调信号不占用终端设备在网络设备预先配置的时域资源中可能不能进行传输的部分资源，从而实现了用于解调上行数据的解调信号在免授权频谱上的正确传输。
图3为本申请实施例提供的另一种上行信号的传输方法300的示意性流程图，如图3所示。
310、网络设备接收终端设备在免授权频谱上的第一时间单元上发送的第一解调信号和第一传输块速率匹配得到的上行数据，其中，所述第一解调信号用于解调所述上行数据，所述第一解调信号占用的符号不包括第一符号。

可选地，在本实施例的一个可能的实现方式中，所述网络设备还可以进一步接收所述终端设备在所述第一时间单元上发送的第二解调信号，其中，所述第二解调信号用于解调所述上行数据，所述第二解调信号占用的符号不包括所述第一符号。
在一个具体的实现过程中，所述第一解调信号可以包括解调参考信号(Demodulation Reference Signal，DMRS)，所述第二解调信号可以包括上行控制信息(Uplink Control Information，UCI)，或者所述第一解调信号可以包括UCI，所述第二解调信号可以包括DMRS，本实施例对此不进行特别限定。

或者，再例如，所述第二解调信号占用的符号可以包括所述第一解调信号占用的符号前面的最后一个符号。以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号3，第二解调信号占用的符号则可以包括符号2，如图2C所示。
或者，再例如，所述第二解调信号占用多个符号，所述第二解调信号占用的符号中的第一个符号为 所述第一解调信号占用的符号后面的第一个符号。以第一时间单元为一个包括14个符号的时隙为例，符号从0开始编号，即一个时隙包括符号0、符号1，……，符号13，若所述第一符号为符号0，且第一解调信号占用的符号为符号1，第二解调信号占用的符号中的第一个符号则可以为符号2。
