Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种无线通信方法、终端设备和网络设备。
背景技术
在新无线(New Radio，NR)系统中定义了多种时隙结构，例如：上行时隙、下行时隙以及灵活时隙。上行时隙包括的符号均为上行符号，因此，上行时隙也被称为全上行时隙。下行时隙包括的符号均为下行符号，因此，下行时隙也被称为全下行时隙。灵活时隙包括至少一个灵活符号。
目前，网络设备可以通过高层信令(即高层参数)指示时隙格式，终端设备根据该时隙格式可以确定上行时隙、下行时隙以及灵活时隙的位置。目前终端设备只能将上行时隙用于上行重复传输，导致灵活时隙无法用于上行重复传输，从而造成上行传输资源利用率低的问题。类似地，在其他上行传输中也可能存在该问题。此外，上行时隙是用于传输上行数据的时隙，然而，针对某一信道，是否可以在上行时隙上进行数据传输也是本申请要解决的技术问题。
发明内容
本申请实施例提供了一种无线通信方法、终端设备和网络设备，对于灵活时隙，通过第一指示信息可以指示该灵活时隙是否用于上行传输，从而可以提高资源利用率，此外，对于上行时隙，通过第一指示信息也可以明确指示该上行时隙是否可以用于上行传输。
第一方面，提供一种无线通信方法，包括：终端设备接收第一指示信息，第一指示信息用于指示至少一个目标时隙是否用于目标信道的上行传输或者用于指示至少一个目标时隙是否用于针对上行传输的信道联合估计；终端设备根据第一指示信息进行上行传输。
第二方面，提供一种无线通信方法，包括：网络设备发送第一指示信息，第一指示信息用于指示至少一个目标时隙是否用于目标信道的上行传输或者用于指示至少一个目标时隙是否用于针对上行传输的信道联合估计。
第三方面，提供一种终端设备，包括：通信单元，用于：接收第一指示信息，第一指示信息用于指示至少一个目标时隙是否用于目标信道的上行传输或者用于指示至少一个目标时隙是否用于针对上行传输的信道联合估计；根据第一指示信息进行上行传输。
第四方面，提供一种网络设备，包括：通信单元，用于发送第一指示信息，第一指示信息用于指示至少一个目标时隙是否用于目标信道的上行传输或者用于指示至少一个目标时隙是否用于针对上行传输的信道联合估计。
第五方面，提供了一种终端设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第一方面或其各实现方式中的方法。
第六方面，提供了一种网络设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第二方面或其各实现方式中的方法。
第七方面，提供了一种装置，用于实现上述第一方面至第二方面中任一方面或其各实现方式中的方法。
具体地，该装置包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该装置的设备执行如上述第一方面至第二方面中任一方面或其各实现方式中的方法。
第八方面，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第二方面中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产品，包括计算机程序指令，计算机程序指令使得计算机执行上述第一方面至第二方面中任一方面或其各实现方式中的方法。
第十方面，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第二方面中任一方面或其各实现方式中的方法。
综上，一方面，对于灵活时隙，通过第一指示信息可以指示该灵活时隙是否用于上行传输，从而可以提高资源利用率，此外，对于上行时隙，通过第一指示信息也可以明确指示该上行时隙是否可以用于上行传输。另一方面，本申请提供的第一指示信息可以携带在用于调度上行传输的消息中，而无需使用其他DCI来携带该信息，从而可以防止该信息丢失，而导致网络设备和终端设备对用于上行传输的时隙理解不一致的问题。

如上所述，在NR系统中定义了多种时隙结构，例如：上行时隙、下行时隙以及灵活时隙。上行时隙包括的符号均为上行(Uplink，U)符号。下行时隙包括的符号均为下行(Downlink，D)符号。灵活时隙包括至少一个灵活符号，即当一个时隙包括至少一个灵活符号时，该时隙被称为灵活时隙。其中，每个时隙结构对应一个索引。
应理解的是，时隙结构也被称为时隙格式，本申请对此不做限制。
图2A至图2D为灵活时隙的示意图，如图2A至图2D分别所示的灵活时隙，其均包括灵活符号。
二、NR中的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)重复传输以及物理上行控制信道(Physical Uplink Control Channel，PUCCH)的重复传输
在NR系统中，为了支持高可靠低时延(Ultra-Reliable and Low Latency Communication，URLLC)业务，采用了上行数据传输重复发送来提高传输可靠性。应理解的是，PUSCH重复传输、上行数据传输重复发送以及上行重复传输是等价的，本申请对此描述方式不做限制。
其中，网络设备可以通过下行控制信息(Downlink Control Information，DCI)调度上行重复传输，该DCI中可以包括：上行重复传输的传输次数K，该传输次数可以是名义(nominal)重复传输次数，即网络设备指示的重复传输次数，但是实际重复传输次数可能小于或等于该传输次数。或者，该传输次数可以是实际(actual)重复传输次数。
目前网络设备可以通过高层参数TDD-UL-DL-ConfigurationCommon或TDD-UL-DL-ConfigDedicated指示时隙格式，终端设备根据该时隙格式可以确定时隙中哪些符号是上行符号、下行符号以及灵活符号，即终端设备可以根据该时隙格式确定上行时隙、下行时隙以及灵活时隙的位置，目前终端设备只能在上行时隙上进行上行重复传输，导致灵活时隙无法用于上行重复传输，从而造成上行传输资源利用率低的问题。
一方面，在根据高层参数确定的时隙格式的基础上，网络设备可以通过DCI动态指示时隙格式，即通过DCI将至少一个灵活符号修改为上行符号或者下行符号。如果通过DCI将所有的灵活符号修 改为上行符号或者下行符号，这时也不存在灵活时隙的情况，但是若该DCI丢失，导致网络设备认为经过修改后，所有的上行时隙都可以用于上行重复传输，但是，由于终端设备未接收到该DCI，终端设备仍然通过高层参数指示的时隙格式，确定上行时隙可以用于上行重复传输，这将导致网络设备和终端设备对用于上行重复传输的时隙理解不一致的问题。如果通过DCI将部分灵活符号修改为上行符号或者下行符号，这时还会存在灵活时隙的情况，一方面，若该DCI丢失，导致网络设备认为经过修改后，所有的上行时隙都可以用于上行重复传输，但是，由于终端设备未接收到该DCI，终端设备仍然通过高层参数指示的时隙格式，确定上行时隙可以用于上行重复传输，这将导致网络设备和终端设备对用于上行重复传输的时隙理解不一致的问题。另一方面，由于可能存在灵活时隙，但是终端设备仍然只能在上行时隙上进行上行重复传输，导致灵活时隙无法用于上行重复传输，从而造成上行传输资源利用率低的问题。
例如：图3为上行重复传输对应的时隙分布示意图，如图3所示，假设终端设备根据上述高层参数半静态指示的时隙格式或者根据DCI动态指示的时隙格式，确定出在时隙1上包括的都是下行符号，即时隙1是下行时隙，其无法用于上行重复传输，而时隙2包括灵活符号，即时隙2是灵活时隙，因此，其也无法用于上行重复传输，最终终端设备在时隙0和时隙3上进行上行重复传输。
另一方面，如上所述，上行时隙是用于传输上行数据的时隙，然而，针对某一信道，是否可以在上行时隙上进行数据传输也是本申请亟待解决的技术问题。
应理解的是，为了提高PUCCH传输的覆盖性能，3GPP R17标准也采用了PUCCH的重复传输。
三、基于竞争的四步随机接入过程的流程交互图。
图4是基于竞争的四步随机接入过程的流程交互图。
如图4所示，该随机接入流程可以包括以下四个步骤：
步骤1，Msg 1。
终端设备向网络设备发送Msg 1，以告诉网络设备该终端设备发起了随机接入请求，该Msg 1中携带随机接入前导码(Random Access Preamble，RAP)，或称为随机接入前导序列、前导序列、前导码等。同时，Msg 1还可以用于网络设备能估计其与终端设备之间的传输时延并以此校准上行时间。
具体而言，终端设备选择preamble索引(index)和用于发送preamble的PRACH资源；然后该终端设备在PRACH上传输Preamble。其中，网络设备会通过广播系统信息系统信息块(System Information Block，SIB)来通知所有的终端设备，允许在哪些个时频资源上传输preamble，例如，SIB1。
步骤2，Msg 2。
网络设备在接收到终端设备发送的Msg 1后，向终端设备发送Msg 2，即随机接入响应(Random Access Response，RAR)消息。该Msg 2中例如可以携带时间提前量(Time Advance，TA)、上行授权指令例如上行资源的配置、以及临时小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identity，TC-RNTI)等。
终端设备则在随机接入响应时间窗(RAR window)内监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以用于接收网络设备回复的RAR消息。该RAR消息可以使用相应的随机接入无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)进行解扰。
如果终端设备在该RAR时间窗内没有接收到网络设备回复的RAR消息，则认为此次随机接入过程失败。
如果终端设备成功地接收到一个RAR消息，且该RAR消息中携带的前导码索引(preamble index)与终端设备通过Msg 1发送的前导码的索引相同时，则认为成功接收了RAR，此时终端设备就可以停止RAR时间窗内的监听了。
其中，Msg 2中可以包括针对多个终端设备的RAR消息，每一个终端设备的RAR消息中可以包括该终端设备所采用的随机接入前导码标识(RAP Identify，RAPID)、用于传输Msg 3的资源的信息、TA调整信息、TC-RNTI等。
步骤3，Msg 3。
终端设备在收到RAR消息后，判断该RAR是否为属于自己的RAR消息，例如终端设备可以利用前导码标识进行核对，在确定是属于自己的RAR消息后，终端设备在RRC层产生Msg 3，并向网络设备发送Msg 3。其中，需要携带终端设备的标识信息等。
具体地，针对不同的随机接入触发事件，4步随机接入过程的步骤3中的Msg 3可以包括不同的内容，以进行调度传输(Scheduled Transmission)。
例如，对于初始接入的场景，Msg 3可以包括RRC层生成的RRC连接请求(RRC Connection Request)，其中至少携带终端设备的非接入层(Non-Access Stratum，NAS)标识信息，还可以携带 例如终端设备的服务临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)或随机数等。
又例如，对于连接重建场景，Msg 3可以包括RRC层生成的RRC连接重建请求(RRC Connection Re-establishment Request)且不携带任何NAS消息，此外还可以携带例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)和协议控制信息(Protocol Control Information，PCI)等。
又例如，对于切换场景，Msg 3可以包括RRC层生成的RRC切换完成消息(RRC Handover Confirm)和终端设备的C-RNTI，还可携带例如缓冲状态报告(Buffer Status Report，BSR)；对于其它触发事件例如上/下行数据到达的场景，Msg 3至少需要包括终端设备的C-RNTI。
步骤4，Msg 4。
网络设备向终端设备发送Msg 4，终端设备正确接收Msg 4完成竞争解决(Contention Resolution)。例如在RRC连接建立过程中，Msg 4中可以携带RRC连接建立消息。
由于步骤3中的终端设备会在Msg 3中携带自己唯一的标识，例如C-RNTI或来自核心网的标识信息(比如S-TMSI或一个随机数)，从而网络设备在竞争解决机制中，会在Msg 4中携带终端设备的唯一标识以指定竞争中胜出的终端设备。而其它没有在竞争解决中胜出的终端设备将重新发起随机接入。
需要说明的是，如果网络设备没有正确收到Msg 3，会通过DCI指示Msg 3的重传的调度信息。如上所述，为了提高PUSCH传输的覆盖性能，3GPP R17标准采用了PUSCH的重复传输，这其中也包括了Msg 3PUSCH的重复传输，涉及Msg 3的初传的上行重复传输和重传的上行重复传输。
四、一个传输块(Transmission Block，TB)的多时隙传输
目前第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)在版本(Release，R)17中，计划标准化一种新型的PUSCH的传输方案，其主要思想是将一个TB块映射到多个时隙上以增强覆盖。这种方式称为一个TB的多时隙传输(TB over Multi-slot，TBoMS)。图5为TB一个TB的多时隙传输的示意图，如图5所示，一个TB经信道编码后，最终可以映射到4个时隙进行传输。可选的，在此基础上，也可以进一步对映射于多个时隙的TB再以多个时隙为单位重复传输。
五、联合信道估计
3GPP R17中，计划标准化上行重复传输的联合信道估计，即网络设备根据上行重复传输占用的多个时隙中的解调参考信号(Demodulation Reference Signal，DMRS)进行联合信道估计，以提高信道估计的准确性。对于联合信道估计，需要确定进行联合信道估计的时隙数或者上行重复传输的重复传输次数，网络设备的联合信道估计会假设多个时隙的DMRS的是相关的，包括功率、天线端口、预编码不变，相位连续等。图6为联合信道估计的的示意图，如图6所示，网络设备可以根据时隙0至时隙3上的DMRS进行联合信道估计。
下面将对本申请技术方案进行详细阐述：
图7为本申请实施例提供的一种无线通信方法的交互流程图，如图7所示，该方法包括如下步骤：
S710：网络设备向终端设备发送第一指示信息，第一指示信息用于指示至少一个目标时隙是否用于目标信道的上行传输。
S720：终端设备根据第一指示信息进行上行传输。
可选的，关于目标信道以及上行传输存在如下几种可实现方式，但不限于此：
可实现方式一：目标信道是目标PUSCH，该目标信道的上行传输是目标PUSCH的上行重复传输。
可实现方式二：目标信道是目标PUCCH，该目标信道的上行传输是目标PUCCH的上行重复传输。
可实现方式三：目标信道是目标PUSCH，该目标PUSCH承载Msg 3，基于此，该目标信道的上行传输是承载Msg 3的初传的上行重复传输。
可实现方式四：目标信道是目标PUSCH，该目标PUSCH承载Msg 3，基于此，该目标信道的上行传输是承载Msg 3的重传的上行重复传输。
可实现方式五：目标信道是目标PUSCH，该目标PUSCH承载一个TB的多时隙传输，基于此，该目标信道的上行传输是该TB的多时隙传输。
应理解的是，目标PUSCH特指某一个PUSCH，目标PUCCH特指某一个PUCCH。
可选的，上述每个目标时隙可以是灵活时隙或者上行时隙，例如：上述至少一个目标时隙都是灵活时隙，或者都是上行时隙，又或者部分是灵活时隙，其余部分是上行时隙，本申请对此不做限制。
应理解的是，用于目标信道的上行传输的目标时隙可以被称为可用时隙，因此，第一指示信息用于指示至少一个目标时隙是否用于目标信道的上行传输，也被描述为第一指示信息用于指示至少一个 目标时隙是否为可用时隙。
下面针对可实现方式一进行说明：
可选的，针对目标PUSCH的上行重复传输情况，上述第一指示信息可以携带在用于调度该上行重复传输的第一DCI中。
可选的，该第一DCI中可以包括：目标PUSCH的重复传输次数，该重复传输次数可以是名义重复传输次数K1或者实际重复传输次数K2，K1、K2均为大于1的整数。所谓名义重复传输次数K1指的是网络设备为终端设备配置的目标PUSCH的重复传输次数，但是终端设备实际的重复传输次数可能小于或等于该名义重复传输次数。所谓名义重复传输次数K1指的是终端设备针对目标PUSCH的实际重复传输次数。
应理解的是，若第一DCI包括目标PUSCH的名义重复传输次数K1，那么上行重复传输的K1次重复传输对应K1个连续时隙，K1个连续时隙构成第一时隙集合。上述至少一个目标时隙是该第一时隙集合中的时隙。需要说明的是，该第一时隙集合也可以是网络设备向终端设备配置的任一个时隙集合，本申请对如何确定第一时隙集合不做限制。
应理解的是，若第一DCI包括目标PUSCH的实际重复传输次数K2，那么终端设备可以根据网络设备为终端设备配置的重复传输起始位置以及实际重复传输次数K2依次查找到K2个可用时隙。
应理解的是，为了将上述不同可实现方式中的可用时隙进行区分，在可实现方式一种，可以将可用时隙称为第一时隙。
可选的，假设上述至少一个目标时隙均为灵活时隙，那么第一指示信息的长度或者占用的比特数可以是任一种，但不限于此：
(1)第一指示信息的长度为1比特。
应理解的是，假设至少一个目标时隙是一个灵活时隙，那么该第一指示信息用于指示该灵活时隙是否用于目标信道的上行传输。假设至少一个目标时隙是多个灵活时隙，那么该第一指示信息用于联合指示(即同时指示)这些灵活时隙是否用于目标PUSCH的上行传输。
可选的，对于灵活时隙，网络设备可以根据目标PUSCH在该灵活时隙中的符号来确定该灵活时隙是否用于目标PUSCH的上行传输。其中，当网络设备确定目标PUSCH在该灵活时隙中的符号不是下行符号，那么确定该灵活时隙可以用于目标PUSCH的上行传输，相反，当网络设备确定目标PUSCH在该灵活时隙中的符号是下行符号，那么确定该灵活时隙不可以用于目标PUSCH的上行传输。
应理解的是，本申请对网络设备如何确定灵活时隙是否用于目标PUSCH的上行传输，不做限制。
可选的，假设至少一个目标时隙是多个灵活时隙，第一指示信息在联合指示这些灵活时隙是否用于目标PUSCH的上行传输时，如果这些灵活时隙中存在至少一个不能用于目标PUSCH的上行传输时，网络设备通过第一指示信息指示这些灵活时隙不可以用于目标PUSCH的上行传输。相反，如果这些灵活时隙全部都能用于目标PUSCH的上行传输时，网络设备通过第一指示信息指示这些灵活时隙可以用于目标PUSCH的上行传输。

(2)第一指示信息长度为N1比特，N1比特与至少一个目标时隙一一对应。N1为大于1的整数，N1比特中每一比特用于指示对应的目标时隙是否用于上行传输。

示例性的，图8为本申请实施例提供的PUSCH的上行重复传输的示意图，如图8所示，当DCI调度PUSCH重复传输4次，假设重复传输所在的时隙集合为连续的4个时隙，如果这4个时隙中包含灵活时隙，需要通过DCI指示灵活时隙是否可以用于PUSCH传输。如图8所示，终端设备可以通过高层信令TDD-UL-DL-ConfigurationCommon或TDD-UL-DL-ConfigDedicated指示的时隙格式，确定时隙0和时隙3所在的时隙为上行时隙，该上行时隙被理解为可以用于该PUSCH的重复传输，但是对于时隙1和时隙2，高层信令指示为灵活时隙。终端设备通过调度该PUSCH重复传输的DCI中携带的第一指示信息确定灵活时隙是否用于PUSCH的重复传输。如图8所示，这里网络设备通过第一指示信息指示时隙1和时隙2不用于该PUSCH的重复传输。

应理解的是，本申请对网络设备如何确定上行时隙是否用于多时隙传输，不做限制。
可选的，假设至少一个目标时隙是多个上行时隙，第一指示信息在联合指示这些上行时隙是否用于多时隙传输时，如果这些上行时隙中存在至少一个不能用于多时隙传输时，网络设备通过第一指示信息指示这些上行时隙不可以用于多时隙传输。相反，如果这些上行时隙全部都能用于多时隙传输时，网络设备通过第一指示信息指示这些上行时隙可以用于多时隙传输。

应理解的是，本申请对网络设备如何确定上行时隙是否用于多时隙传输，不做限制。
(3)第一指示信息长度为K3比特，K3比特与K3个连续时隙一一对应。K3比特中每一比特用于指示对应的连续时隙是否用于多时隙传输。
其中，K3是上述第二时隙集合包括的时隙个数。

(1)第一指示信息的长度为1比特。
应理解的是，假设至少一个目标时隙是一个上行时隙或者灵活时隙，那么该第一指示信息用于指示该上行时隙或者上行时隙是否用于多时隙传输。假设至少一个目标时隙包括上行时隙和灵活时隙，那么该第一指示信息用于联合指示(即同时指示)这些时隙是否用于多时隙传输。
应理解的是，本申请对网络设备如何确定灵活时隙用于多时隙传输可参考上文，本申请对此不再赘述，另外，本申请对网络设备如何确定上行时隙是否用于多时隙传输不做限制。
(2)第一指示信息的长度为2比特。其中，2比特分别用于指示上述至少一个目标时隙中的上行时隙是否用于多时隙传输，以及指示上述至少一个目标时隙中的灵活时隙是否用于多时隙传输。

综上，一方面，对于灵活时隙，通过第一指示信息可以指示该灵活时隙是否用于上行传输，从而可以提高资源利用率，此外，对于上行时隙，通过第一指示信息也可以明确指示该上行时隙是否可以用于上行传输。另一方面，本申请提供的第一指示信息可以携带在用于调度上行传输的消息中，而无需使用其他DCI来携带该信息，从而可以防止该信息丢失，而导致网络设备和终端设备对用于上行传输的时隙理解不一致的问题。
需要说明的是，如果用于调度上行传输的消息中未携带第一指示信息，那么终端设备可以根据高层信令TDD-UL-DL-ConfigurationCommon或TDD-UL-DL-ConfigDedicated指示的时隙格式，或者进一步根据其他DCI确定的时隙格式，确定时隙集合中的灵活时隙是否用于上行传输。

需要说明的是，联合信道估计可以是针对PUSCH的联合信道估计，或者是针对PUCCH的联合信道估计，又或者是针对一个TB的多时隙传输的联合信道估计，本申请对此不做限制。
应理解的是，由于网络设备的联合信道估计会假设多个时隙的DMRS的是相关的，因此，在本申请中，可以将联合信道估计描述为DMRS绑定等，本申请对此不做限制。
