Description

信号接收、发送方法及装置 技术领域
本申请涉及通信领域，尤其涉及一种信号接收、发送方法及装置。
背景技术
无线通信技术的飞速发展，导致频谱资源日益紧缺，促进了对于非授权频段的探索。第三代合作计划(3rd generation partnership project，3GPP)分别在版本13(Release-13，简称R-13)和版本14中引入了授权频谱辅助接入(License Assisted Access，简称LAA)和增强的授权频谱辅助接入(enhanced LAA，简称eLAA)技术，即在非授权频谱上非独立(Non-standalone)的部署长期演进(Long Term Evolution，LTE)/演进的LTE(LTE-advance，简称LTE-A)系统，通过授权频谱的辅助来最大化利用非授权频谱资源。
多时间单元调度方案是指通过一个调度指示信息来调度多个时间单元的方案。当前正在研究的一种多时间单元调度场景是基站(例如eNodeB)等网络设备向终端设备(例如手机)发送一个调度指示信息，以指示终端设备在多个时间单元上进行上行传输的场景。也就是说，网络设备通过向终端设备发送一个调度指示信息，能够指示该终端设备在多个时间单元上占用授权频谱或非授权频谱反馈该网络设备所需的数据。可以理解，通过一个调度指示信息来调度多个时间单元，可以有效减少信令消耗。因此，需要研究网络设备怎样通过一个调度信息来准确地指示终端设备在多个时间单元上，向其反馈其所需信息的方案。
发明内容
本申请实施例公开了一种信号接收、发送方法及装置，可以应用于通信系统，例如车与任何事物通信(vehicle-to-everything，V2X)、车与车的通信(vehicle to vehicle，V2V)、车间信息交互(long term evolution-vehicle，LTE-V)、车联网、机器类通信(machine type communication，MTC)、物联网(internet of things，IoT)、机器间信息交互(long term evolution-machine，LTE-M)，机器到机器通信(machine to machine，M2M)等，能够在多个时间单元中接收或发送至少两种不同类型的信号，提高通信效率。
第一方面，本申请实施例提供了一种信号接收方法，该方法可包括：网络设备向终端设备发送调度信息；所述调度信息包括第一指示信息，所述第一指示信息用于指示M个时间单元的时域位置，所述M为大于1的整数；在所述M个时间单元中的N个时间单元上接收第一信号；所述N为大于0且不大于所述M的整数。
调度信息可以是下行控制信息(downlink control information，DCI)，也可以是无线资源控制(radio resource control，RRC)信令，还可以是其他调度信令。可选的，在该M个时间单元中除该N个时间单元之外的任一时间单元上接收的信号不为该第一信号。优选的，M大于N。也就是说，网络设备只在该M个时间单元中的N个时间单元上接收该第一信号。网络设备在该M个时间单元上可以接收至少两种类型的信号。举例来说，网络设备在N个时间单元上接收第一信号，在该M个时间单元中除该N个时间单元之外的(M-N)个时间单元上接收第二信号，该第一信号和该第二信号不同。该第一信号可以仅包括信道状 态信息(channel state information，CSI)，也可以仅包括上行数据，还可以包括CSI和上行数据，还可以是其他信号，本申请不作限定。可选的，本申请实施例提供的信号接收方法应用于非授权频谱场景，即网络设备在非授权频谱上接收第一信号。可以理解，网络设备可以在多个时间单元上接收至少两种不同类型的信号，这样该网络设备可以在终端设备的一次上行传输中接收到至少两种类型的信号，能够有效减少终端设备发送上行传输的次数以及该网络设备接收数据的次数，通信效率高。
本申请实施例中，网络设备在终端设备的一次上行传输中接收至少两种类型的信号，能够有效提高通信效率。
在一个可选的实现方式中，所述第一信号包括信道状态信息CSI和/或上行数据。
可以理解，该第一信号可以仅包括CSI，也可以仅包括上行数据，还可以同时包括CSI和上行数据。上行数据可以是终端设备向网络设备发送的任意数据。在第一信号包括CSI时，网络设备可以同时接收到CSI和其他信号，该网络设备可以根据CSI来相应的调整其调度策略；在第一信号不包括CSI时，网络设备可以同时接收到两种不同类型的信号，通信效率高。
在一个可选的实现方式中，所述第一指示信息包括第一索引，所述第一索引在第一配置表中指示的时域位置为所述M个时间单元的时域位置，所述第一配置表由网络设备配置给终端设备，或者所述第一配置表为系统预设，或所述第一配置表存储于所述终端设备。
可选的，该第一指示信息可以是3GPP 38.212中定义的时域资源分配(Time domain resource assignment，TDRA)字段。示例性地，该第一配置表可以是物理上行共享信道(physical uplink shared channel，PUSCH)time domain resource allocation列表。网络设备可以通过该第一索引指示该M个时间单元的时域位置。终端设备可以在该第一配置表中查找该第一索引所指示的时域位置，得到该M个时间单元的时域位置。该第一索引可以是该第一指示信息对应的码点(codepoint)或取值。举例来说，第一指示信息对应的codepoint＝0，终端设备在第一配置表中查找第一行配置信息，获取多个时间单元的时域位置。例如获取到网络设备调度连续的四个时间单元，该四个时间单元中第一个时间单元相对于接收到调度信息的时隙1偏移为2个时隙，即该多个时间单元位于时隙3、时隙4、时隙5以及时隙6。其中，终端设备在时隙1接收到调度信息，每个时间单元为一个时隙。可选的，网络设备通过向终端设备发送RRC信令来配置该第一配置表。或者可选的，第一配置表为系统预设的。
可选的，终端设备可以根据该第一索引在CSI上报配置信息中所指示的时间偏移列表中，查找用于CSI上报的时间单元的时域位置。可以理解，终端设备根据调度信息，可以获取到一个或一组或多个或多组CSI上报配置信息。如果每个或每组CSI上报配置信息对应多个时间偏移列表，则在该多个时间偏移列表中查找的多个时间偏移值中按照一定的规则选择一个或多个，例如选择最大的或者最小的时间偏移值。示例性地，CSI上报配置信息可通过3GPP 38.331中定义的CSI-ReportConfig指示，时间偏移列表通过reportSlotOffsetList进行指示。可以理解，终端设备可以使用该第一索引从第一配置表中查找该M个时间单元的时域位置，也可以使用该第一索引从CSI上报配置信息所指示的时间偏移列表中查找该N个时间单元的时域位置。
在该实现方式中，通过第一索引和第一配置表相结合的方式指示M个时间单元的时域位置，在准确地指示该M个时间单元的时域位置的情况下，能够减少调度信息携带的指示信息。
在一个可选的实现方式中，所述调度信息还包括第二指示信息，所述第二指示信息用于指示所述N个时间单元的时域位置。
在该实现方式中，调度信息还包括用于指示N个时间单元的时域位置的第二指示信息，以便于终端设备根据该第二指示信息，准确、快速地确定该N个时间单元的时域位置。
在一个可选的实现方式中，所述第二指示信息包括第二索引，所述第二索引在第二配置表中指示的时域位置为所述N个时间单元的时域位置，所述第二配置表由网络设备配置给终端设备，或者所述第二配置表为系统预设，或所述第二配置表存储于所述终端设备。
该第二配置表可以是CSI上报配置信息中所指示的时间偏移列表。示例性地，所述CSI上报配置信息可通过3GPP 38.331中定义的CSI-ReportConfig指示，时间偏移列表通过reportSlotOffsetList进行指示。举例来说，终端设备可以根据调度信息获取N个CSI-ReportConfig，进而获得相应的N个reportSlotOffsetList，然后查找每个reportSlotOffsetList中的该第二索引所指示的时间偏移值，得到一个或多个时间偏移值(即offset信息)。例如对于第一个或第一组reportSlotOffsetList，根据该第二索引得到的时间偏移值为3，对于对于第二个或第二组reportSlotOffsetList，根据该第二索引得到的时间偏移值为4，则表示相对于接收到调度信息的时隙1分别偏移3个时隙和4个时隙的时间单元用于CSI的发送，即时隙4和时隙5。可选的，在该实现方式中第一信号可以仅包括CSI。
在该实现方式中，通过第二索引和第二配置表相结合的方式指示N个时间单元的时域位置，在准确地指示该N个时间单元的时域位置的情况下，能够减少调度信息携带的指示信息。
在一个可选的实现方式中，所述第二指示信息指示用于发送第一信号的时间单元的个数为所述N个。可选的，所述第二指示信息包括数量信息N，用于指示发送第一信号的时间单元的个数为所述N个。
终端设备可以根据预设规则确定该M个时间单元中N个时间单元用于发送第一信号。示例性的，该M个时间单元中的前N个时间单元或者最后N个时间单元，用于发送第一信号。在该实现方式中，上述第一信号可以包括CSI和上行数据。可以理解，在知道M个时间单元的时域位置时，该M个时间单元中的前N个时间单元的时域位置也就能够知道。在该实现方式中，调度信息包含的数量信息可以准确地指示N个时间单元的时域位置，占用的比特位或字节很少，减少信令消耗。
在一个可选的实现方式中，所述第二指示信息指示所述N个时间单元相对于所述M个时间单元的位置。
可选的，该第二指示信息包括一个或多个时间偏移值。举例来说，N个时间单元为连续的，该第二指示信息包括一个时间偏移值，该时间偏移值用于指示该N时间单元中的第一个或最后一个时间单元相对于该M个时间单元的位置。又举例来说，N为4，该第二指示信息包括的时间偏移值依次为1、3、5、6，则该第二指示信息指示M个时间单元中第1、3、5、6个时间单元为该N个时间单元包括的时间单元。可选的，第二指示信息包括一个 位图(bitmap)，该位图包括所述M个比特位，每个比特位对应所述M个时间单元中的一个时间单元，每个比特位指示在一个时间单元是否发送第一信号。假设M为4，则“1001”表示在第一个时间单元和第四个时间单元上发送第一信号，即N个时间单元包括第一时间单元和第四个时间单元。在该实现方式中，上述第一信号可以包括CSI和上行数据。可以理解，在知道M个时间单元的时域位置以及该N个时间单元相对于该M个时间单元的位置时，可以快速、准确地知道该N个时间单元的时域位置。
在一个可选的实现方式中，所述调度信息还包括第三指示信息，所述第三指示信息用于指示所述N个时间单元中用于仅发送CSI的时间单元和/或用于发送CSI和上行数据的时间单元。
可选的，网络设备采用如3GPP 38.212中定义的UL-SCH indicator(对应于第三指示信息)指示在该N个时间单元中各时间单元上仅传输CSI，还是CSI和数据一起传输。可选的，该第三指示信息为调度信息中新定义的字段。第三指示信息可以指示N个进行CSI上报的时间单元中，哪些仅传输CSI，哪些传输CSI和上行数据。示例性地，第三指示信息可以通过位图的方式，用包括N个比特位的位图指示，每一个比特位对应一个时间单元。假设有2个时间单元可以进行CSI上报，“10”则在表示该2个时间单元中第一个时间单元上仅发送CSI(即CSI only)，在另一个时间单元上发送CSI和上行数据。在一些应用场景中，一次CSI反馈可能不需要占用一个时间单元，这时终端设备可以在同一个时间单元上同时发送CSI和数据，以提高资源利用率。在实际应用中，网络设备可以根据实际需要指示终端设备在一些时间单元上仅传输CSI，在另一些时间单元上同时传输CSI和数据，可以更充分的利用时频资源。
在该实现方式中，可以准确地指示终端设备在N个时间单元上传输不同类型的数据，提高资源利用率。
在一个可选的实现方式中，所述调度信息还包括第四指示信息，所述第四指示信息用于指示N个CSI上报配置信息。
该第四指示信息可以对应N个码点(codepoint)/取值(value)，每个codepoint/取值指示一个或一组CSI上报配置信息，该N个codepoint/取值指示N个或N组CSI上报配置信息。codepoint/取值是指码点或取值。该第四指示信息可以对应N个数值，该N个数值既可以称为N个码点，也可以称为N个取值。也就是说，码点和取值可以视为同一概念，均表示数值。一个指示信息对应的codepoint/取值是指该指示信息对应的一个或多个数值。
示例性地，该第四指示信息包含N个子字段，每个子字段对应一个codepoint/取值。示例性地，可以在RRC信令中进行配置所述CSI上报配置信息的列表，然后通过调度信息中的字段(即第四指示信息)和RRC信令相结合的方式进行指示，即通过第四指示信息对应的codepoint/取值跟RRC中所定义的CSI上报配置信息进行关联。网络设备可以通过RRC信令配置终端设备的CSI上报配置信息。终端设备通过该第四指示信息对应的一个codepoint/取值可以确定一个或一组CSI上报配置信息。举例来说，终端设备配置有多个或多组CSI上报配置信息，每个或每组CSI上报配置信息关联一个codepoint/取值，该终端设备可以根据第四指示信息对应的每个codepoint/取值来确定一个或一组CSI上报配置信息，进而进行CSI反馈。可选的，终端设备的系统中有预设的CSI上报配置信息列表，所述第 四指示信息可以采用CSI上报配置信息的索引进行指示。第四指示信息中有一个或多个索引信息，终端设备根据该索引信息即可获知进行CSI上报所需的配置信息。可选的，调度信息为一个DCI。一个CSI上报配置信息可以包含以下一种或多种信息的组合：CSI上报类型；CSI上报时间信息(可以是周期、相对于某一时间的时间偏移、绝对时间等一种或多种组合)，CSI资源信息(可以是用于进行CSI测量的资源信息，例如信道状态信息参考信号(channel state information-reference signal,CSI-RS)的资源信息和/或用于进行CSI测量对应同步信号块(synchronization signal block，SSB)的资源信息和/或用于进行干扰测量的资源信息)等。在该实现方式中，利用第四指示信息指示N个或N组CSI上报配置信息，以便于终端设备在N个时间单元上上报所需的CSI。
在一个可选的实现方式中，所述调度信息还包括第五指示信息，所述第五指示信息用于指示所述终端设备进行CSI上报。
示例性地，该第五指示信息，可以采用如3GPP 38.212中定义的CSI request字段。可选的，第五指示信息也可以采用1比特(bit)的字段用于指示终端设备是否需要进行CSI上报。例如用比特“0”表示终端设备不需要进行CSI上报，用比特“1”表示该终端设备需要进行CSI上报，还可以为其他指示方式，本发明不做限定。

优选的，M大于N。可选的，终端设备在该M个时间单元中除该N个时间单元之外的任一时间单元上发送的信号不为该第一信号。也就是说，终端设备在一次上行传输过程中，可以在不同的时间单元上发送不同类型的信号。这样终端设备就可以通过一次上行传输向网络设备发送多种信号，可以有效减少该终端设备进行上行传输的次数，进而提高通信效率。
本申请实施例中，终端设备在一次上行传输过程中，在多个时间单元上发送至少两种不同类型的信号，能够有效提高通信效率。

在该实现方式中，根据指示信息和/或配置列表，能够快速、准确地确定时间单元的时域位置。

示例性地，该第一配置表可以是PUSCH time domain resource allocation列表。可选的，所述第一指示信息包括第一索引。网络设备可以通过该第一索引指示该M个时间单元的时域位置。终端设备可以在该第一配置表中查找该第一索引所指示的时域位置，得到该M个时间单元的时域位置。该第一索引可以是该第一指示信息对应的codepoint/取值。
可选的，所述第二指示信息指示用于反馈第一信号的时间单元的个数为所述N个。例如第二指示信息包括数量信息N，用于指示发送第一信号的时间单元的个数为所述N个。终端设备可以根据预设规则确定该M个时间单元中N个时间单元用于发送第一信号。示例性的，该M个时间单元中的前N个时间单元或者最后N个时间单元，用于发送第一信号。也就是说，终端设备可以根据预设规则和该第二指示信息，确定M个时间单元中哪N个时间单元用于发送第一信号。
可选的，所述第二指示信息用于指示所述N个时间单元相对于所述M个时间单元的位置。这样知道M个时间单元的时域位置之后，终端设备根据该第二指示信息就可以确定该N个时间单元的时域位置。可选的，该第二指示信息包括一个或多个时间偏移值，这些时间偏移值可以表示该N个时间单元相对于所述M个时间单元的位置。举例来说，N为4，该第二指示信息包括的时间偏移值依次为1、3、5、6，则该第二指示信息指示M个时间单元中第1、3、5、6个时间单元为该N个时间单元包括的时间单元。可选的，第二指示信息包括一个位图(bitmap)，该位图包括所述M个比特位，每个比特位对应所述M个时间单元中的一个时间单元，每个比特位指示一个时间单元是否发送第一信号。假设M为4，则“1001”表示在第一个时间单元和第四个时间单元上发送第一信号，即N个时间单元包括第一时间单元和第四个时间单元。
可选的，该第二指示信息用于指示该N个时间单元的时域位置分别相对于接收到调度信息的时隙的时间偏移。
在该实现方式中，终端设备先确定M个时间单元的时域位置，再根据该M个时间单元的位置和/或第二指示信息确定N个时间单元的时域位置，能够快速地确定各时间单元的时域位置。
在一个可选的实现方式中，所述第一信号包括上行数据；所述在所述M个时间单元中的N个时间单元向所述网络设备发送第一信号之前，所述方法还包括：

可选的，网络设备采用如3GPP 38.212中定义的UL-SCH indicator(对应于第三指示信息)指示在该N个时间单元中各时间单元上仅传输CSI，还是传输CSI和上行数据。可选的，该第三指示信息为调度信息中新定义的字段。第三指示信息可以指示N个进行CSI上报的时间单元中，哪些是仅传输CSI，哪些传输CSI和上行数据。示例性地，第三指示信息可以通过位图的方式，用包括N个比特位的位图指示，每一个比特位对应一个时间单元。假设有2个时间单元可以进行CSI上报，“10”则在表示该2个时间单元中第一个时间单元 上仅发送CSI(即CSI only)，在另一个时间单元上发送CSI和上行数据。在一些应用场景中，一次CSI反馈可能不需要占用一个时间单元，这时可以在同一个时间单元上同时发送CSI和数据，以提高资源利用率。在实际应用中，网络设备可以根据实际需要指示终端设备在一些时间单元上仅传输CSI，在另一些时间单元上同时传输CSI和数据，可以更充分的利用时频资源。
在一个可选的实现方式中，所述调度信息还包括第四指示信息，所述第四指示信息用于指示N个CSI上报配置信息。
该第四指示信息可以对应N个码点(codepoint)/取值，每个codepoint/取值指示一个或一组CSI上报配置信息。也就是说，该第四指示信息指示N个或N组CSI上报配置信息。示例性地，该第四指示信息包含N个子字段，每个子字段对应一个codepoint/取值。示例性地，该第四指示信息可以在RRC信令中进行配置，然后通过调度信息中的字段(即第四指示信息)和RRC信令相结合的方式进行指示，即通过第四指示信息对应的codepoint/取值跟RRC中所定义的CSI上报配置信息进行关联。网络设备可以通过RRC信令配置终端设备的CSI上报配置信息。终端设备通过该第四指示信息对应的一个codepoint/取值可以确定一个或一组CSI上报配置信息。举例来说，终端设备配置有多个或多组CSI上报配置信息，每个或每组CSI上报配置信息关联一个codepoint/取值，该终端设备可以根据第四指示信息对应的每个codepoint/取值来确定一个或一组CSI上报配置信息，进而进行CSI反馈。可选的，终端设备的系统中有预设的CSI上报配置信息列表，所述第四指示信息可以采用CSI上报配置信息的索引进行指示。第四指示信息中有一个或多个索引信息，终端设备根据该索引信息即可获知进行CSI上报所需的配置信息。可选的，调度信息为一个DCI。
在该实现方式中，调度信息包括的第四指示信息用于指示N个CSI上报配置信息，以便于终端设备根据该第四指示信息在一次上行传输中上报多个CSI，效率高。
在一个可选的实现方式中，所述调度信息还包括第五指示信息，所述第五指示信息用于指示所述终端设备进行CSI上报。
示例性地，该第五指示信息，可以采用如3GPP 38.212中定义的CSI request字段。可选的，第五指示信息也可以采用1比特(bit)的字段用于指示终端设备是否需要进行CSI上报。例如用比特“0”表示终端设备不需要进行CSI上报，用比特“1”表示该终端设备需要进行CSI上报，还可以为其他指示方式，本发明不做限定。

具体实施方式
本申请的说明书实施例和权利要求书及上述附图中的术语“第一”、“第二”、和“第三”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元。方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。“和/或”用于表示在其所连接的两个对象之间选择一个或全部。例如“A和/或B”表示A、B或A+B。
本申请实施例公开了信号接收方法、信号发送方法及设备及相关设备，通过对数据和第一信号上报的独立指示/联合指示，实现在多时间单元调度场景下的第一信号上报，避免网络设备和终端设备之间对于第一信号上报的指示信息之间出现混淆。该第一信号包括CSI和/或上行数据。也就是说，网络设备(例如基站)可以通过一个调度信息指示终端设备(例如手机)进行上行传输的多个时间单元，并指示该终端设备在哪个或哪些时间单元上发送第一信号。为了更好理解本申请实施例公开的信号接收方法、信号发送方法及设备及相关设备，下面先对本申请实施例适用的网络构架进行描述。本申请实施例公开的方法可以应用于5G新无线接入技术(New RAT(radio access technology)，NR)系统；也可以应用于其它通信系统，只要该通信系统中存在实体需要指示另外的实体在多个时间单元的哪个或哪些时间单元上发送第一信号，和/或，存在实体需要在一次传输的多个时间单元中的部分时间单元上接收或接收第一信号。下面先介绍本申请实施例公开的方法所适用的一种网络架构。
请参阅图1，图1是本申请实施例公开的一种网络构架示意图。如图1所示，该网络构架适用于多时间单元调度场景，即一次上行传输或下行传输占用多个时间单元发送数据或信号的场景。网络设备是网络侧的一种用于发射或接收信号的实体，如gNB。终端设备是用户侧的一种用于接收或发射信号的实体，如手机。由于基站和UE的应用场景较多，下面以基站作为网络设备的示例，以用户设备(user equipment，UE)作为终端设备的示例。 如图1所示，基站(base station)和UE1～UE6组成一个通信系统。在该通信系统中，基站可以给UE1～UE6发送调度信息；UE1～UE6可以根据该调度信息上报相应的信息。此外，UE4～UE6也可以组成一个通信系统。在该通信系统中，UE5也可以发送调度信息给UE4、UE6；UE4、UE6也可以给UE5发送针对该调度信息的反馈信息。举例来说，基站可以给UE1～UE6发送CSI request即CSI上报请求指示(调度信息的一种示例)；UE1～UE6可以根据该CSI reques进行CSI上报。此外，UE4～UE6也可以组成一个通信系统。在该通信系统中，UE5也可以发送CSI request给UE4、UE6；UE4、UE6也可以给UE5发送CSI上报信息。
下面来详细描述本申请实施例提供的信号接收方法和信号发送方法。
图2为本申请实施例提供的一种信号接收方法流程图。如图2所示，该方法可包括：
201、网络设备向终端设备发送调度信息。
该调度信息包括第一指示信息，该第一指示信息用于指示M个时间单元的时域位置，该M为大于1的整数。该调度信息可以是DCI，也可以是RRC信令，还可以是DCI和RRC信令的组合，还可以是其他调度信令。时间单元可以是子帧、时隙(slot)、微时隙、无线帧、正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号、传输时间间隔(Transmission Time Interval，TTI)等。应理解，时间单元并不限定于列举的几种，还可以是其他时间长度。可选的，图2中的信号接收方法可应用于非授权频谱场景，网络设备在发送调度信息之前需要进行LBT。可选的，在多时间单元调度场景下，网络设备发送的调度信息，应保证用于仅发送CSI的时间单元位于其所调度的多个时间单元之内。可选的，网络设备在向终端设备发送调度信息之前，对信道进行LBT；在信道处于空间状态的情形下，向终端设备发送调度信息。
202、在M个时间单元中的N个时间单元上接收第一信号。
该N为大于0且不大于该M的整数。该第一信号可以包括CSI和/或上行数据。该第一信号既可以是携带信息的信号，也可以是数据。优选的，M大于N。也就是说，网络设备只在该M个时间单元中的N个时间单元上接收该第一信号，在该M个时间单元中除该N个时间单元之外的(M-N)个时间单元上接收其他信号。可选的，本申请实施例提供的信号接收方法应用于非授权频谱场景，即在非授权频谱上接收第一信号。该网络设备向该终端设备发送该调度信息，可指示该终端设备在M个时间单元中的N个时间单元上发送该第一信号。也就是说，该调度信息可调度M个时间单元，并指示该终端设备在其中的N个时间单元上发送第一信号，可以有效节省信令。
本申请实施例中，网络设备可以在终端设备的一次上行传输中接收到至少两种类型的信号，；能够有效减少终端设备发送上行传输的次数以及该网络设备接收数据的次数，通信效率高。
图2仅描述了网络设备执行的操作，为更清楚地描述本申请实施例提供的方法，下面来描述网络设备和终端设备的交互流程。图3为本申请实施例提供的一种网络设备和终端设备的交互方法流程图。如图3所示，该方法可包括：
301、网络设备向终端设备发送调度信息。
该调度信息包括第一指示信息，该第一指示信息用于指示M个时间单元的时域位置， 该M为大于1的整数。
302、终端设备解析调度信息，得到M个时间单元的时域位置以及N个时间单元的时域位置。
303、终端设备在M个时间单元中的N个时间单元上发送第一信号。
在一些实施例中，终端设备在该M个时间单元中除该N个时间单元之外的时间单元上发送第二信号，该第二信号不同于该第一信号。在这些实施例中，网络设备通过向终端设备发送调度信息，可以指示该终端设备在一次上行传输过程中，发送至少两种类型的信号。该调度信息可以准确地指示终端设备在哪些时间单元的时域位置上发送第一信号，在哪些时间单元的时域位置上发送其他信号(例如第二信号)。可选的，图3中的交互方法可应用于非授权频谱场景，终端设备在发送第一信号前需要进行一次或多次LBT。在非授权频谱场景下，通过一个调度信息调度多个时间单元，可以有效降低信令开销以及LBT开销。
可选的，在多时间单元调度场景下，如果调度信息指示的用于仅发送CSI的时间单元落在其所调度的多个时间单元之外，则终端设备默认在该M个时间单元的前N个或最后N个上发送CSI。
可选的，终端设备在执行步骤303之前，可以执行如下操作：对目标信道进行监听；确定所述目标信道处于空间状态。在所述M个时间单元中的N个时间单元向所述网络设备发送第一信号可以是：在所述N个时间单元通过所述目标信道发送第一信号。该目标信道对应的频谱可以是非授权频谱。可选的，该目标信道属于物理上行共享信道。在该实现方式中，终端设备可以执行一次LBT，在监听到目标信道处于空间状态时，通过该目标信道在多个时间单元上进行上行传输，可以有效减少LBT开销。
304、网络设备在M个时间单元中的N个时间单元上接收第一信号。
该第一信号可以包括CSI，也可以包括CSI和上行数据。网络设备可以在多时间单元调度机制下对终端设备进行CSI上报指示，可以有效提高CSI上报的效率。
本申请实施例中，网络设备可以在终端设备的一次上行传输中接收到至少两种类型的信号，能够有效减少终端设备发送上行传输的次数以及该网络设备接收数据的次数，通信效率高。
下面介绍终端设备解析调度信息，得到M个时间单元的时域位置以及N个时间单元的时域位置的几种实现方式。
方式一
在方式一中，第一信号包括CSI且未包括上行数据。上述第一指示信息包括第一索引，该第一索引在第一配置表中指示的时域位置为该M个时间单元的时域位置。该第一配置表由网络设备配置给终端设备，或者该第一配置表为系统预设，或该第一配置表存储于该终端设备。终端设备可以解析该第一指示信息，得到该第一索引；在该第一配置表中查找该第一索引指示的时域位置，得到该M个时间单元的时域位置。示例性的，调度信息为DCI，该第一指示信息可以是DCI中的时域资源指示信息(即TDRA字段)，该第一索引可以是时域资源指示信息对应的codepoint/取值。该第一配置表可以为网络设备预设的或者在RRC信令重定义的PUSCH时域资源配置信息列表(也称PUSCH time domain resource allocation列表)。该第一配置表中详细的配置了上述M个时间单元的时间信息，包括映射方式，起 始时间S，时间偏移K 2，持续时间L等中的一种或多种。表1为一种第一配置表的示例。表1中示出了时间单元为2个时，每个时间单元详细的配置信息。可以理解的，表1仅用于举例说明，在实际配置时第一配置表可以为其他形式，例如将不同时间单元之间公共的信息进行合并或者联合指示，本申请不做限定。可选的，该第一指示信息对应的一个codepoint/取值(即第一索引)对应表1中的一个配置。终端设备根据第一指示信息以及该第一配置表，即可确定上述M个时间单元的时域位置。假定网络设备在时隙1向终端设备发送调度信息，第一指示信息对应的codepoint＝0，终端设备需要在该第一配置表中查找第一行配置信息，获取到M个时间单元的时域位置。例如获取到基站调度连续的2个时间单元，该2个时间单元中第一个时间单元相对于DCI的时间偏移K 2为2个时隙，即该2个时间单元位于时隙3和时隙4。应理解，时间单元不限于时隙，还可以是子帧、无线帧、OFDM符号、微时隙、TTI等。
可选的，该第一指示信息用于指示该M个时间单元的时域位置分别相对于接收到调度信息的时隙的时间偏移。例如，该第一指示信息用于指示4个时间单元分别相对于该终端设备接收到调度信息的时隙1偏移3个时隙、4个时隙、5个时隙以及6个时隙，则该2个时间单元为时隙4、时隙5、时隙6以及时隙7。

该调度信息还包括第二指示信息，该第二指示信息用于指示该N个时间单元的时域位 置。该第二指示信息可以包括第二索引，该第二索引在第二配置表中指示的时域位置为该N个时间单元的时域位置；该第二配置表由网络设备配置给终端设备，或者该第二配置表为系统预设，或该第二配置表存储于该终端设备。终端设备可以解析该第二指示信息，得到该第二索引；在该第二配置表中查找该第二索引指示的时域位置，得到该N个时间单元的时域位置。可选的，第二指示信息隐含在该第一指示信息中，该第二索引为该第一索引。终端设备可以根据该第一索引或该第二索引在CSI上报配置信息所指示的时间偏移列表(对应于上述第二配置表)中，查找用于发送CSI的时间单元的时域位置，得到该N个时间单元的时域位置。终端设备根据调度信息，可以获取到多个或多组CSI上报配置信息(即CSI-ReportConfig信息)，进而获得相应的多个或多组时间偏移列表，例如reportSlotOffsetList。后续再描述终端设备根据调度信息，获取到多个或多组CSI上报配置信息的实现方式。对于每个或每组reportSlotOffsetList，终端设备查找每个或每组reportSlotOffsetList(对应于第二配置表)中该第一索引或第二索引指示的配置信息，得到一个或多个时间偏移值(即offset信息)，然后在该一个或多个offset信息中选择最大的一个，得到每个用于发送CSI的时间单元相对于调度信息的时间偏移值。假定第一索引对应的codepoint＝0，则终端设备查找每个或每组reportSlotOffsetList中第一行的配置信息。假定第二索引对应的codepoint＝3，则终端设备查找每个或每组reportSlotOffsetList中第四行的配置信息。举例来说，对于第一个或第一组reportSlotOffsetList，终端设备根据该第一索引或该第二索引得到的offset信息为3，对于对于第二个或第二组CSI-ReportConfig信息，根据该第一索引或该第二索引得到的offset信息为4，则表示相对于接收到调度信息的时隙1分别偏移3个时隙和4个时隙的时间单元用于发送CSI，即时隙4和时隙5。在一些实施例中，第一配置表可以包含上述第二配置表，终端设备利用该第一指示信息以及该第一配置表可以查找到该M个时间单元的时域位置以及该N个时间单元的时域位置。
终端设备在调度信息指示用于发送CSI的时间单元上仅能发送CSI时，可以结合指示信息和配置列表来确定上述M个时间单元的时域位置以及上述N个时间单元的时域位置。
方式二
在方式二中，第一信号包括CSI和上行数据，或者，仅包括上行数据。方式二中终端设备得到M个时间单元的时域位置的实现方式可以与方式一中终端设备得到M个时间单元的时域位置的实现方式相同，这里不再赘述。在方式二中，终端设备可根据上述M个时间单元的时域位置来确定用于发送第一信号的N个时间单元的时域位置。
可选的，第二指示信息指示用于发送第一信号的时间单元的个数为N个。例如第二指示信息包括数量信息N，指示用于发送第一信号的时间单元的个数为N个。终端设备可以根据预设规则确定该M个时间单元中哪N个时间单元用于发送第一信号。示例性的，终端设备确定该M个时间单元中的前N个时间单元或者最后N个时间单元，用于发送第一信号。由于终端设备已知该M个时间单元的时域位置，该终端设备可以确定该N个时间单元的时域位置。
可选的，该第二指示信息指示该N个时间单元相对于该M个时间单元的位置。这样终端设备在获得M个时间单元的时域位置之后，根据该第二指示信息就可以确定该N个时间单元的时域位置。可选的，该第二指示信息包括一个或多个时间偏移值，这些时间偏移值 可以表示该N个时间单元相对于该M个时间单元的位置。举例来说，N为4，该第二指示信息包括的时间偏移值依次为1、3、5、6，则该第二指示信息指示M个时间单元中第1、3、5、6个时间单元为该N个时间单元包括的时间单元。可选的，第二指示信息包括一个位图(bitmap)，该位图包括该M个比特位，每个比特位对应该M个时间单元中的一个时间单元，每个比特位指示是否在其对应的时间单元上发送第一信号。假设M为4，则“1001”表示在第一个时间单元和第四个时间单元上发送第一信号，即N个时间单元包括第一个时间单元和第四个时间单元。
可选的，该第二指示信息可以包括第三索引，该第三索引在第三配置表中指示的时域位置为该N个时间单元的时域位置；该第三配置表由网络设备配置给终端设备，或者该第三配置表为系统预设，或该第三配置表存储于该终端设备。终端设备可以解析该第二指示信息，得到该第三索引；在该第三配置表中查找该第三索引指示的时域位置，得到该N个时间单元的时域位置。该第三配置表可以为与上述第一配置表类似的配置列表，区别在于该第一配置表中每行为M个时间单元的配置信息，该第三配置表中每行为N个时间单元的配置信息。举例来说，第三索引为3，终端设备查找第三配置表中row index＝4时的K 2取值，得到N个时间单元的时间偏移信息。如果终端设备在时隙n接收到调度信息，则应该在时隙n+K 2发送CSI。
可选的，终端设备根据第一配置表和第二指示信息，确定所述N个时间单元的时域位置。上述第一配置表可以既包括调度信息指示的M个时间单元的时域位置，又包括用于发送第一信号的N个时间单元的时域位置。终端设备可以查询该第二指示信息包括的索引在该第一配置列表中所指示的时域位置，得到该N个时间单元的时域位置。
可选的，该第二指示信息用于指示该N个时间单元的时域位置分别相对于接收到调度信息的时隙的时间偏移。例如，该第二指示信息用于指示2个时间单元分别对应于该终端设备接收到调度信息的时隙1偏移3个时隙和4个时隙，则该2个时间单元为时隙4和时隙5。
终端设备在调度信息指示需要发送的第一信号为CSI和上行数据或者为上行数据时，可以先结合第一指示信息和配置列表来确定上述M个时间单元的时域位置，再根据上述M个时间单元的时域位置确定上述N个时间单元的时域位置。
前述实施例中的第一信号可以包括CSI和上行数据，也可以仅包括CSI。在一些实施例中，该调度信息还包括第三指示信息，所述第三指示信息用于指示所述N个时间单元中用于仅发送CSI的时间单元和/或用于发送CSI和上行数据的时间单元。可选的，第三指示信息为一个包括N个比特位的位图，每一个比特位对应一个时间单元。终端设备可以根据该第三指示信息，确定在哪些时间单元上仅发送CSI，在哪些时间单元上同时发送CSI和上行数据。假设终端设备在2个时间单元可以发送CSI，“10”则表示在该2个时间单元中的第一个时间单元上仅发送CSI(即CSI only)，在另一个时间单元上发送CSI和数据。可选的，第三指示信息包括1个比特位,；若该比特位为1，表示在该N个时间单元上均仅发送CSI；若该比特位为0，表示在该N个时间单元上均发送CSI和上行数据。在一些应用场景中，发送CSI可能不需要占用一个时间单元，这时终端设备可以在同一个时间单元上同时发送CSI和上行数据，以提高资源利用率。在实际应用中，网络设备可以根据实际需要指 示终端设备在一些时间单元上仅传输CSI，在另一些时间单元上同时传输CSI和数据，可以更充分的利用时频资源。
在一些实施例中，该调度信息还包括第四指示信息，该第四指示信息用于指示N个CSI上报配置信息。该第四指示信息可以对应N个码点(codepoint)/取值，每个codepoint/取值指示一个或一组CSI上报配置信息，该N个codepoint/取值指示N个或N组CSI上报配置信息。该第四指示信息可以采用如3GPP 38.212中定义的CSI request字段。示例性地，该第四指示信息包含N个子字段，每个子字段对应一个codepoint/取值。示例性地，该第四指示信息可以在RRC信令中进行配置，然后通过调度信息中的字段(即第四指示信息)和RRC信令相结合的方式进行指示，即通过第四指示信息对应的codepoint/取值跟RRC中所定义的CSI上报配置信息进行关联。网络设备可以通过RRC信令配置终端设备的CSI上报配置信息。终端设备通过该第四指示信息对应的一个codepoint/取值可以确定一个或一组CSI上报配置信息。举例来说，终端设备配置有多个或多组CSI上报配置信息，每个或每组CSI上报配置信息关联一个codepoint/取值，该终端设备可以根据第四指示信息对应的每个codepoint/取值来确定一个或一组CSI上报配置信息，进而进行CSI反馈。可选的，终端设备的系统中有预设的CSI上报配置信息列表，该第四指示信息可以采用CSI上报配置信息的索引进行指示。第四指示信息中有一个或多个索引信息，终端设备根据该一个或多个索引信息即可获知进行CSI上报所需的配置信息。可选的，调度信息为一个DCI。一个CSI上报配置信息可以包含以下一种或多种信息的组合：CSI上报类型；CSI上报时间信息(可以是周期、相对于某一时间的时间偏移、绝对时间等一种或多种组合)，CSI资源信息(可以是用于进行CSI测量的资源信息，例如CSI-RS的资源信息和/或用于进行CSI测量对应SSB的资源信息和/或用于进行干扰测量的资源信息)等。终端设备可以根据第四指示信息指示的N个或N组CSI上报配置信息，在N个时间单元上上发送CSI。在实际应用中，终端设备可以根据一个或一组CSI上报配置信息在一个时间单元上发送相应的CSI。也就是说，在不同时间单元上发送的CSI可以不同。
在一些实施例中，该调度信息还包括第五指示信息，该第五指示信息用于指示该终端设备进行CSI上报。示例性地，该第五指示信息，可以采用如3GPP 38.212中定义的CSI request字段。可选的，第五指示信息也可以采用1比特(bit)的字段用于指示终端设备是否需要进行CSI上报。例如用比特“0”表示终端设备不需要进行CSI上报，用比特“1”表示该终端设备需要进行CSI上报，还可以为其他指示方式，本发明不做限定。可选的，该第五指示信息隐含在上述第四指示信息中。也就是说，终端设备可以根据上述第四指示信息，确定需要进行CSI上报。
前述实施例中描述了网络设备向终端设备发送调度信息，该终端设备在该调度信息指示的M个时间单元中的N个时间单元发送CSI的方案。本申请实施例还提供了一种网络设备不需要发送调度信息，终端设备可在M个时间单元中的多个时间单元上发送第一信号的方案。本申请实施例提供的另一种网络设备和终端设备的交互方法流程图。如图4所示，该方法可包括：
401、终端设备对非授权频谱进行监听。
402、终端设备根据先监听后发送LBT的结果，选择LBT成功的N个时间单元。
N为大于1的整数。终端设备可以通过非授权频谱上的接收功率的大小来判断其忙闲状态，如果接收功率小于一定门限，则认为非授权频谱处于空闲状态，可以在该非授权频谱上发送信号，否则不发送信号。可选的，终端设备在M个时间单元上进行上行传输，在N个时间单元上发送第一信号，在(M-N)个时间单元上发送第二信号，该第二信号不同于该第一信号。该第一信号可以包括CSI和上行数据，也可以仅包括CSI。
403、终端设备向网络设备发送上行控制信息。
该上行控制信息包括该N个时间单元的时域位置的指示信息。可选的，该上行控制信息还包括该M个时间单元的时域位置的指示信息。
404、网络设备根据上行控制信息，确定N个时间单元的时域位置。
该上行控制信息可以包括目标索引；网络设备可以在该第四配置表中查找该目标索引所指示的时域位置，得到该N个时间单元的时域位置。该第四配置表为系统预设，或所述第四配置表存储于所述网络设备。该第四配置表类似于上述第一配置表，这里不再详述。
405、终端设备在N个时间单元上发送第一信号。
406、网络设备在M个时间单元中的N个时间单元上接收第一信号。
可选的，网络设备在(M-N)个时间单元上接收第二信号。
本申请实施例中，终端设备可以根据LBT的结果在多个时间单元向网络设备发送第一信号，只需执行一次LBT就可在多个时间单元上发送第一信号，可以节约信令、降低LBT开销以及降低丢失信道的概率。
