首先，对本申请实施例中用于无线通信的时域资源进行简单说明。
在本申请实施例中，网络设备和终端设备用于无线通信的时域资源在时域上可以划分为多个时间单元。
并且，在本申请实施例中，多个时间单元可以是连续的，也可以是某些相邻的时间单元之间设有预设的间隔，本申请实施例并未特别限定。
在本申请实施例中，时间单元可以是包括用于上行数据传输和/或下行数据传输的时间单元。
在本申请实施例中，对一个时间单元的长度不做限定例如，1个时间单元可以是一个或多个子帧；或者，也可以是一个或多个时隙；或者，也可以是一个或多个符号。
在本申请的实施例中，符号也称为时域符号，可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是单载波频分多址(single carrier frequency division multiple access，SC-FDMA)符号，其中SC-FDMA又称为带有转换预编码的正交频分复用(orthogonal frequency division multiplexing with transform precoding，OFDM with TP)。
在本申请实施例中，对于多个时间单元来说，多个时间单元在时域上是存在时序关系的，且任意两个时间单元对应的时间长度可以相同也可以不同。
下面，为了便于理解，对本申请实施例中涉及的下行数据的传输和上行数据的传输分别进行详细说明。
下行数据的传输
网络设备向终端设备发送下行控制信息(downlink control information，DCI)，解调参考信号(Demodulation Reference Signal，DMRS)和下行数据，该终端设备在接收到该DCI后，根据该DCI可以确定用于发送该下行数据的时频资源、用于发送该下行数据的反馈信息的时频资源以及表示该下行数据的编码方式等信息，根据DMRS进行信道估计，该终端设备基于信道估计的结果和DCI对该下行数据进行解调译码。若该终端设备针对该下行数据解调译码成功，则表示该终端设备成功接收该下行数据，该终端设备会生成确认应答(Acknowledgment，ACK)，并且，在该DCI中所指示的时频资源上发送ACK；若该终端设备针对该下行数据解调译码失败，则表示该终端设备未成功接收该下行数据，该终端设备会生成否认应答(Negative Acknowledgement，NACK)，并且，在该DCI中所指示的时频资源上发送NACK。
基于上述描述，终端设备处理下行数据的处理时段可以为以下任一种定义：
定义1
处理时段包括终端设备进行信道估计和对下行数据进行解调译码占用的时段。
定义2
处理时段包括终端设备进行信道估计、对下行数据进行解调译码和发送反馈信息的占用的时段。
定义3
处理时段包括终端设备对下行数据进行解调译码和发送反馈信息占用的时段。
定义4
处理时段包括终端设备对下行数据进行解调译码占用的时段。
为了便于描述，在对本申请实施例举例说明时，以定义1中处理时段为例进行描述。但本申请实施例对终端设备处理下行数据的处理时段不做任何限定。
需要说明的是，终端设备在接收到DMRS后，才可以进行信道估计，进而，对下行数据进行解调译码处理。在一个物理下行共享信道(Physical Downlink Shared Channel，PDSCH)中，可能会配置多个DMRS，终端设备一般需要将一个PDSCH中的所有DMRS全部接收完成，才完成信道估计。
一般情况下，终端设备可以一边接收下行数据，一边对下行数据进行处理。
如图2所示，网络设备发送下行数据后，该终端设备在接收到DMRS后，虽然该终端设备没有接收完该下行数据，该终端设备可以在信道估计后，对已经接收到的部分下行数据进行解调译码，这样，在该终端设备进行信道估计的时间点开始到该完整接收下行数据的时段内，即图2所示的处理时段#C1，该终端设备可以边接收下行数据边解调译码下行数据。图2所示的处理时段#C是该终端设备处理该下行数据的时段，即，该终端设备对该下行数据进行信道估计、解调译码占用的时间。
从上述描述可以看出，在一定程度上，终端设备接收DMRS的时间会影响终端设备处理下行数据的处理时段。如图3所示，假设，终端设备处理下行数据的处理时长相同，在图3的第一个图中，系统为下行数据配置了一个DMRS，则终端设备在接收到该DMRS后就可以进行信道估计，进而进行解调译码；在图3的第二个图中，系统为下行数据配置了两个DMRS，则终端设备只有在接收到第二个DMRS后才能完成信道估计，进而进行解调译码。因此，相比于配置一个DMRS，配置两个DMRS明显延迟了终端设备处理下行数据的处理时段。
上行数据的传输
上行数据的传输有两种传输方式：第一种传输方式是基于授权的传输方式，另一种传输方式是基于免授权的传输方式。
下面，分别对上述两种传输方式进行说明。
基于授权的传输方式
在上行数据的传输中，当终端设备有上行业务传输需求的时候，需要在物理上行控制信道(Physical Uplink Control Channel，PUCCH)上向网络设备发送调度请求(Scheduling Request，SR)，通知该网络设备有上行数据传输需求。该网络设备在接收到SR后，会向该终端设备发送调度信息，调度信息也称为上行授权(Up Link Grant，UL Grant)信息。该终端设备收到调度信息后，对上行数据进行编码调制处理后，在该调度信息指示的上行 资源上发送该上行数据。这种基于授权的传输机制可靠性高，但是需要经过终端设备发送调度请求、网络设备发送调度信息之后才能进行上行数据传输，从而导致上行数据的传输时延较大。因此，基于授权的传输方式不利于对时延要求较高的数据的传输。
需要说明的是，基于授权的传输方式也可以称为基于调度的传输方式。
基于免授权的传输方式终端设备的上行传输不需要通过网络设备的调度完成，这种免授权(Grant free，GF)的传输可以称为自主上行(Autonomous UL，AUL)传输，也可以称为配置授权的上行传输(configured grant UL transmission，CGL)，也可以称为基于竞争机制(contention based)的传输。具体地，网络设备将GF资源通过半静态方式分配给终端设备，终端设备在进行上行传输时，不需要向网络设备发送调度请求SR以及等待网络设备发送UL Grant信息，可以直接通过GF资源发送上行数据，从而减少传输时延。因此，基于免授权的传输方式有利于对时延要求较高的数据的传输。
在上行传输中，终端设备处理上行数据的处理时段包括对上行数据进行编码占用的时段，或者，终端设备处理上行数据的处理时段包括对上行数据进行编码和发送上行数据占用的时段。本申请实施例对终端设备处理上行数据的处理时段不做任何限定。
以上，对本申请实施例中涉及的技术术语和数据传输的流程做了简单描述。下面，对本申请实施例的无线通信的方法进行详细说明。
如图4所示，网络设备在时间单元#A上发送下行数据#A，随后，在时间单元#B上发送下行数据#B。终端设备处理该下行数据#A的处理时段为处理时段#A，处理该下行数据#B的处理时段为处理时段#B。该处理时段#A和该处理时段#B部分重合，也就是说，该终端设备还未处理完该下行数据#A的情况下，就需要开始处理该下行数据#B。但是，在重合时段中，该终端设备可能并没有能力同时处理两个数据，使得下行数据#B的处理会被延迟，从而影响下行数据#B的传输时延。
因此，本申请实施例提供了一种无线通信的方法，有助于降低后接收到的业务数据的处理时延。
以下，结合图5至图8，对本申请一实施例的无线通信的方法进行详细说明。
图5是根据本申请实施例提供的无线通信的方法200的示意性交互图。下面，对方法200的每个步骤进行详细说明。
在本申请实施例中，以终端设备和网络设备作为执行方法200的执行主体为例，对方法200进行说明。作为示例而非限定，执行方法200的执行主体也可以是对应终端设备的芯片和对应网络设备的芯片。
在S210中，网络设备向终端设备发送DCI#1(即，第一DCI的一例)，该DCI#1包括指示信息#1(即，第一指示信息的一例)，该指示信息#1用于指示时间单元#3(即，第三时间单元的一例)，该时间单元#3用于承载下行数据#1(即，第一下行数据的一例)的反馈信息。
也就是说，该网络设备通过该DCI#1中的指示信息#1通知该终端设备在该时间单元#3上发送该下行数据#1的反馈信息。
应理解，该DCI#1还包括用于指示该网络设备发送该下行数据#1的时间单元(例如，时间单元#1)的信息以及用于指示该下行数据的编码方式的信息等信息，可以使得该终端设备在接收到该DCI#1后，基于该DCI#1正确处理该下行数据#1以及发送该下行数据#1 的反馈信息。
需要说明的是，时间单元#1可以包括一个时间单元，也可以包括多个时间单元，本申请实施例不做任何限定。下文中涉及的时间单元#2、时间单元#3、时间单元#4和时间单元#5的解释同该时间单元#1的解释，为了简洁，后续不再做描述。
在S220中，包括S221和S222，下面，分别对S221和S222说明。
在S221中，该网络设备在时间单元#1(即，该第一时间单元的一例)上发送该下行数据#1。
对应地，该终端设备通过该DCI#1确定该网络设备会在该时间单元#1上发送下行数据，则，该终端设备会在该时间单元#1上开始接收并处理该下行数据#1。
在S222中，该网络设备在时间单元#2(即，第二时间单元的一例)上发送下行数据#2(即，第二下行数据的一例)。
同理，对应地，该终端设备可以通过网络设备发送的DCI(例如，DCI#2)确定该网络设备会在该时间单元#2上发送下行数据，则，该终端设备会在该时间单元#2上开始接收该下行数据#2。
其中，该时间单元#2位于该时间单元#1之后，终端设备对该下行数据#2做接收处理的处理时段#1(即，第一处理时段的一例)与该终端设备对该下行数据#2做接收处理的处理时段#2(即，第二处理时段的一例)部分重合。
也就是说，该网络设备在发送该下行数据#1之后，也发送了该下行数据#2。在这个过程中，该终端设备在开始接收该下行数据#2时，该终端设备并未处理完该下行数据#1，即，该处理时段#1与该处理时段#2部分重合；或者说，该时间单元#1与该时间单元#2间隔较近；或者说，在重合时段，该终端设备会需要更多的处理资源(例如，计算资源、缓存数据的资源等)来处理两个下行数据，但是，该终端设备并没有足够的资源处理下行数据，这样情况可以认为是，该终端设备处理该下行数据#1的处理资源与该终端设备处理该下行数据#2的处理资源发生冲突，从而，会使得两个下行数据的处理都受到影响，该终端设备无法在该网络设备调度的资源上发送反馈信息，影响了数据传输的传输性能。
作为示例而非限定，在某些场景下，时间单元#2与时间单元#1可以部分重叠。例如，当终端设备支持在一个载波内激活多个带宽部分(bandwidth part，BWP)或支持在多个载波同时进行数据传输的时候，可能会出现在在第一个载波或BWP上先调度了下行数据#1，然后再在第二个载波或BWP上调度了下行数据#2。假设，一个时隙包括14个符号，用于传输下行数据#1的时间单元#1的起始符号和结束符号分别为第一时隙的第一个符号和第13个符号；用于传输下行数据#2的时间单元#2的起始符号和结束符号分别为第一时隙的第5个符号和第7个符号。那么，在这种场景下，时间单元#2的起始符号在时间单元#1的起始符号之后但在时间单元#1的结束符号之前，也就是说，时间单元#2与,时间单元#1是部分重叠的。为了避免出现上述场景中两个下行数据都无法按时反馈的问题，提高数据传输的传输性能，这种情况下，终端设备可以优先处理一种上行数据，尽量保证一种上行数据的传输性能。
在S230中，该终端设备在该时间单元#3上，不发送该下行数据#1的反馈信息。
由于终端设备没有在时间单元#3之前完成对下行数据#1的处理，所以终端设备没有在该时间单元#3上发送下行数据#1的反馈信息。
在一种可能的实现方式中，该终端设备在接收到该下行数据#2后，暂停处理该下行数据#1。
这样，该终端设备可以将资源预留出来用于处理后来接收到的下行数据#2。
作为示例而非限定，该终端设备也可以对下行数据#1和下行数据#2做并行处理，但在具体实现过程中，会分配更多的处理资源用来处理下行数据#2。
对于网络设备来说，该网络设备确知发送该下行数据#1的时间单元#1和发送该下行数据#2的时间单元#2，基于该时间单元#1、该时间单元#2和终端设备处理下行数据的大概占用的时长，可以通过相关公式进行计算，确定该终端设备处理该下行数据#1的处理时段#1与该终端设备处理该下行数据#2的处理时段#2部分重合，这种情况下，该网络设备确知该终端设备未完成对该下行数据#1的处理，即终端设备也不会在该时间单元#3上发送该下行数据#1的反馈信息。
因此，该网络设备不会在该时间单元#3上接收该下行数据#1的反馈信息。
如前所述，该终端设备不会在该时间单元#3上发送该下行数据#1的反馈信息，意味着该终端设备并没有完成对该下行数据#1的处理，预留了处理资源来处理该下行数据#2，因此，该终端设备在接收到该下行数据#2后，开始处理该下行数据#2，并且，处理完毕后可以基于网络设备的调度发送该下行数据#2的反馈信息。
S211，该网络设备向该网络设备发送DCI#2，该DCI#2包括指示信息#2(即，第二指示信息的一例)，该指示信息#2用于指示时间单元#5；
S240，该终端设备在该时间单元#5上发送该下行数据#2的反馈信息。
应理解，该DCI#2还包括用于指示该网络设备发送该时间单元#2的信息以及用于指示该下行数据#2的编码方式的信息等信息，可以使得该终端设备在接收到该DCI#2后，基于该DCI#2正确处理该下行数据#2以及发送该下行数据#2的反馈信息。
因此，本申请实施例提供的无线通信的方法，在网络设备在第一时间单元上发送第一下行数据，在位于该第一时间单元之后的第二时间单元上发送第二下行数据，并且，在终端设备有处理资源的冲突时，该终端设备在该网络设备调度的时间单元(例如，第三时间单元)上不发送该第一下行数据的反馈信息，可以使得该终端设备将未用来处理该第一下行数据的处理资源来处理该第二下行数据，降低了该第二下行数据的传输时延，从而提高了该第二下行数据的传输性能。
其中，针对终端设备有处理资源冲突可以有多种判断准则：例如，判断准则可以是终端设备处理该下行数据#1的处理时段和处理该下行数据#2的处理时段存在部分重合；再例如，判断准则也可以是终端设备无法按时对该下行数据#1和该下行数据#2中的至少一个进行反馈，这里所谓的按时进行反馈指在DCI指示的时频资源上进行反馈。
在一种可能的实现方式中，网络设备可以通过终端设备上报的处理下行数据的能力的信息以及时间单元#1和时间单元#2的时序关系确定终端设备有处理资源冲突的情况。其中，终端设备处理下行数据的能力至少包含终端设备处理下行数据需要的时间N1作为示例而非限定，N1可以定义为从下行数据的最后一个符号到最早能够进行上行反馈的第一个符号的时间长度，例如，网络设备发送下行数据的时间单元的最后一个符号为第n个符号，通过DCI调度的终端设备最快能够发送反馈信息的是第m个符号开始反馈，则N1＝m-n+1。
假设，网络设备发送下行数据#1的第一个符号为第k1个符号，发送下行数据#1的最后一个符号为第k2个符号，发送下行数据#2的第一个符号为第k3个符号，发送下行数据#2的最后一个符号为第k4个符号，DCI指示在第j个符号上开始发送下行数据#2的反馈信息，其中k1,k2,k3,k4和j为非负整数，且它们的计数起点相同。如果k2+N1大于或等于k，则认为下行数据#1的接收处理的第一处理时段和下行该数据#2的接收处理的第二处理时段部分重合；如果k2+N1小于k，则认为上述第一处理时段和第二处理时段没有重合，其中k为大于等于k3且小于等于k4的非负整数。如果第一处理时段和第二处理时段有重合，且满足k+2*N1大于或等于j，则可以认为终端设备处理下行数据#1和下行数据#2的处理资源有冲突，需要使用本申请实施例中的方法对下行数据#1和下行数据#2进行处理；如果第一处理时段和第二处理时段没有重合，或k+2*N1小于j，则可以认为终端设备处理下行数据#1和下行数据#2的处理资源没冲突。
在本申请实施例的S230中，该终端设备在该时间单元#3上不发送该下行数据#1的反馈信息，有两种可能的情况，情况#1和情况#2，下面，分别对这两种情况进行说明。
情况#1
由于时间单元#1和时间单元#2是网络设备通过DCI调度的资源，该网络设备根据时间单元#1和时间单元#2的时序关系可以确定该终端设备处理下行数据#1的处理时段和处理下行数据#2的处理时段会存在重合，也可以确定该终端设备不会按照调度的资源在时间单元#1上发送下行数据#1的反馈信息，或者说，也可以确定该终端设备无法及时处理下行数据#1。
基于此，该终端设备可以一直不发送该下行数据#1的反馈信息，即，该终端设备不仅不会在该时间单元#3上发送该下行数据#1的反馈信息，也不会延后发送该下行数据#1的反馈信息。
随后，该网络设备可以对下行数据#1做重传处理，即，在其他时间单元上向该终端设备重新发送下行数据#1。
情况#2
该终端设备在时间单元#4(即，第四时间单元的一例)发送该下行数据#1的反馈信息，该时间单元#4位于该时间单元#3之后。
其中，该时间单元#4是位于该终端设备针对该下行数据#1处理完毕的时间单元(记为时间单元#9)之后的距离该时间单元#9最近的可用的时间单元。或者说，该时间单元#4是位于该时间单元#9之后的第一个可用的时间单元。
在此种情况下，该终端设备会在处理完该下行数据#2之后，继续处理该下行数据#1，在处理完该下行数据#1的时间单元(即，时间单元#9)之后，会在距离该时间单元#9最近的可用的时间单元(即，时间单元#4)上发送该下行数据#1的反馈信息。
其中，可用的时间单元可以有多种解释：
可用的时间单元可以是指不需要对下行数据#2进行反馈的时间单元。否则，若同一个时间单元既发送下行数据#1的反馈信息也发送下行数据#2的反馈信息，会有冲突，无法对下行数据#1进行反馈。此外，若考虑时分双工(Time Division Duplexing，TDD)的场景，可用的时间单元必须是上行时间单元。
在本申请实施例中，该时间单元#4的具体位置与终端设备的处理能力有关。其中， 终端设备的处理能力具体指，该终端设备在处理完该下行数据#2后继续处理该下行数据#1的过程中，是否有能力继续处理该下行数据#1中剩余的未处理的下行数据。若该终端设备无法继续处理该下行数据#1中剩余的未处理的下行数据，在处理完该下行数据#2后，只能从头开始重新处理完整的该下行数据#1。
下面，分别从终端设备能继续处理该下行数据#1中剩余的未处理的下行数据(即，情况#2A)和不能继续处理该下行数据#1中剩余的未处理的下行数据(即，情况#2B)对时间单元#4进行说明。
情况#2A
该时间单元#4与该终端设备对该下行数据#2接收处理完毕的时间单元(记为时间单元#10)之间间隔M1个时间单元，该M1个时间单元的时长大于或等于该处理时段#1与该处理时段#2重合的时段对应的时长，该M1为大于或等于1的整数。
也就是说，若该终端设备可以继续处理该下行数据#1中未处理的下行数据，该终端设备在处理完该下行数据#2后，只需要继续占用重合的时段对应的时长来处理该下行数据#1中剩余的下行数据就可以，随后，在间隔该时间单元#9之后的最近的可用的时间单元(即，时间单元#4)上发送该下行数据#1的反馈信息。
若该终端设备在处理完该下行数据#1的时间单元#9之后距离该时间单元#9最近的时间单元是可用的时间单元，则该M1个时间单元大约等于该处理时段#1和处理时段#2重合的时段对应的时长；若该终端设备在处理完该下行数据#1的时间单元#9之后距离时间单元#9最近的时间单元不是可用的时间单元，则该M1个时间单元大于该处理时段#1和处理时段#2重合的时段对应的时长。
需要说明的是，在实际处理中，基于很多实现因素，该M1个时间单元可能并不是严格意义上的完全等于处理时段#1和处理时段#2的重合时段，因此，这里的等于可以理解为大约等于。例如，该终端设备在处理完该下行数据#2后继续处理该下行数据#1时，时间上可能会有延迟；再例如终端设备处理完该下行数据#的1时间单元可能与发送该下行数据#1的反馈信息的时间单元是同一个时间单元。
图6所示为根据本申请一实施例提供的下行传输的示意图。如图6所示，以时隙为传输数据的基本单位，网络设备在时隙#1(即，时间单元#1)上发送下行数据#1，并且，通过DCI#1指示终端设备在时隙#5(即，时间单元#3)上发送该下行数据#1的反馈信息。随后，网络设备又在时隙#2(即，时间单元#2)上发送下行数据#2，并且，通过DCI#2指示终端设备在时隙#6(即，时间单元#5)上发送该下行数据#2的反馈信息。但是，该终端设备处理该下行数据#1的处理时段#1与处理该下行数据#2的处理时段#2部分重合，重合时段对应的时长为T1。终端设备接收到下行数据#2之后可以暂停处理下行数据#1，优先处理下行数据#2，从而，使得该终端设备不会或者来不及在时隙#5上发送下行数据#1的反馈信息，但是，可以在时隙#6上发送该下行数据#2的反馈信息，保证了下行数据#2的传输时延。对于下行数据#1来说，处理完下行数据#2后，继续处理时长T1，大致在时隙#8(即，时间单元#9)上才能处理完，由于在时隙#8后面的时隙#9是最近的可用的时隙，因此，该终端设备可以在时隙#9上发送该下行数据#1的反馈信息。
当然，若在时隙#8后面的时隙#9不是最近的可用的时间单元，即，时隙#9被其他数据或信息的传输占用，该终端设备可以在时隙#9之后的最近的可用的时隙上发送该下行 数据#1的反馈信息。
情况#2B
该时间单元#4与该终端设备对该下行数据#2接收处理完毕的时间单元#10之间间隔M2个时间单元，该M2个时间单元的时长大于或等于该处理时段#1对应的时长，该M2为大于或等于1的整数。
也就是说，若该终端设备不能继续处理该下行数据#1中未处理的下行数据，该终端设备在处理完下行数据#2后，需要从头开始处理完整的该下行数据#1，随后，在距离该时间单元#9之后的最近的可用的时间单元(即，时间单元#4)上发送该下行数据#1的反馈信息。
同理，若该终端设备在处理完该下行数据#1的时间单元#9之后距离该时间单元#9的最近的时间单元是可用的时间单元，则该M2个时间单元大约等于该处理时段#1对应的时长；若该终端设备在处理完该下行数据#1的时间单元#9之后距离该时间单元#9的时间单元不是可用的时间单元，则该M2个时间单元大于该处理时段#1对应的时长。
这里对于等于的解释同情况#B对等于的解释相同，为了简洁，此处不再赘述。
图7所示为根据本申请一实施例提供的下行传输的另一示意图。如图7所示，以时隙为传输数据的基本单位，网络设备在时隙#1(即，时间单元#1)上发送下行数据#1，并且，通过DCI#1指示终端设备在时隙#5(即，时间单元#3)上发送该下行数据#1的反馈信息。随后，网络设备又在时隙#2(即，时间单元#2)上发送下行数据#2，并且，通过DCI#2指示终端设备在时隙#6(即，时间单元#5)上发送该下行数据#2的反馈信息。但是，该终端设备处理该下行数据#1的处理时段#1与处理该下行数据#2的处理时段#2部分重合，该终端设备在接收到下行数据#2之后可以暂停处理下行数据#1，优先处理下行数据#2，从而，使得该终端设备不会或者来不及在时隙#5上发送该下行数据#1的反馈信息，但是，可以在时隙#6上发送该下行数据#2的反馈信息，保证了下行数据#2的传输时延。对于下行数据#1来说，由于不能继续处理未处理的下行数据#1，必须从头开始处理完整的下行数据#1，需要继续处理与处理时段#1相同时长，大致在时隙#9(即，时间单元#9)上才能处理完下行数据#1。由于在时隙#9后面的时隙#10是最近的可用的时隙，因此，该终端设备可以在时隙#10上发送该下行数据#1的反馈信息。
当然，若在时隙#9后面的时隙#10不是最近的可用的时间单元，即，时隙#10被其他数据或信息的传输占用，该终端设备可以在时隙#10之后的最近的可用的时隙上发送该下行数据#1的反馈信息。
在本申请实施例中，对于情况#2中该终端设备会在该时间单元#4上发送该下行数据#1的反馈信息的情况，无论是上述情况#2A还是情况#2B，该网络设备都可以通过该时间单元#1、时间单元#2的先后顺序以及终端设备继续处理剩余下行数据的能力确定该终端设备发送该下行数据#1的反馈信息的位置(即，时间单元#4)从而，在该时间单元#4上接收该下行数据#1的反馈信息。
在一种可能的实现方式中，若该网络设备确知该终端设备能够继续处理剩余的下行数据，则确定的时间单元#4是情况#2A中的时间单元#4；若该网络设备确知该终端设备不能继续处理剩余的下行数据，则确定的时间单元#4是情况#2B中的时间单元#4。无论哪种情况，该网络设备可以仅检测一次就可以接收该下行数据#1的反馈信息。
在另一种可能的实现方式中，若该网络设设备并不确知该终端设备是否能够继续处理剩余的下行数据，则会同时考虑情况#2A和情况#2B，即，在情况#2A中的时间单元#4和情况#2B中的时间单元#4上都会检测，以便于能够接收到该下行数据#1的反馈信息。
现有的5G移动通信系统可以同时传输不同类型的数据，不同类型的数据对移动通信系统的需求不同。其中，5G中典型的两种数据类型是增强型移动宽带(enhanced mobile broadband，eMBB)数据和高可靠低时延通信(ultrareliable and low latencycommunications，URLLC)数据。
相比于eMBB数据，URLLC数据对时延要求极高，在本申请实施例中，如何在5G移动通信系统降低URLLC数据的传输时延，从而提高数据的传输性能，也是需要考虑的问题。
由于URLLC数据对时延要求极高，对于在时间单元#1之后的时间单元#2上发送的下行数据#2，若下行数据#2是URLLC数据，优先处理下行数据#2，有助于提高对时延要求高的数据的传输性能。
因此，终端设备可以通过下行数据的优先级来确定是否优先处理该下行数据#2。例如，若该终端设备确定的该下行数据#2的优先级高于该下行数据#1的优先级，则该终端设备暂停处理该下行数据#1，优先处理该下行数据#2，执行方法200的技术方案；若该下行数据#2的优先级低于或等于该下行数据#1的优先级，则该终端设备继续处理该下行数据#1，延后处理该下行数据#2，使得该终端设备可以在网络设备调度的时间单元#3上发送该下行数据#1的反馈信息，不在网络设备调度的该时间单元#5上发送该下行数据#2的反馈信息。
这里所说的下行数据的优先级可以从可靠性、传输速率等方面考虑来定义下行数据的优先级：若从数据传输的时延和可靠性方面考虑，时延短且可靠性高的数据的优先级高于时延长且可靠性低的数据的优先级，例如，URLLC数据的优先级高于eMBB数据的优先级。
在本申请实施例中，终端设备可以基于终端设备是否能够确定下行数据的数据类型的情况分别基于方式1和方式2确定是否优先处理该下行数据#2。
方式1
在终端设备可以确定下行数据的数据类型的情况下，根据该下行数据#1的数据类型和该下行数据#2的数据类型确定该下行数据#1和该下行数据#2的优先级，进而确定是否优先处理该下行数据#2。
其中，数据类型可以是eMBB、URLLC和mMTC等可以区分性能需求的数据类型。
举例来说，从数据传输的时延、可靠性等方面考虑，URLLC数据的优先级可以高于eMBB数据的优先级。
例如，若下行数据#2为URLLC数据，下行数据#1为eMBB数据，则下行数据#2的优先级高于下行数据#1的优先级，则该终端设备可以暂停处理该下行数据#1，优先处理下行数据#2，执行方法200的技术方案；若下行数据#1为URLLC数据，下行数据#2为eMBB数据，则下行数据#2的优先级低于下行数据#1的优先级，则该终端设备继续处理下行数据#1，延后处理该下行数据#2；若下行数据#1和下行数据#2都为eMBB数据，则该终端设备可以继续处理下行数据#1，延后处理该下行数据#2，也可以进一步基于eMBB 数据的业务子类型优先处理下行数据#2，例如，若下行数据#1是eMBB数据中的文件下载数据，下行数据#2是eMBB数据中的网页浏览数据，则可以优先处理下行数据#2。
基于上述描述，表1所示为下行数据的数据类型与处理方式的对应关系。
表1
Figure PCTCN2019086351-appb-000001
在本申请实施例中，该终端设备可以通过各种方式确定下行数据的数据类型。
在一种可能的实现方式中，该终端设备可以根据DCI确定下行数据的数据类型。例如，该终端设备可以根据DCI中携带的载荷(payload size)或者无线网络临时鉴定(Radio Network Tempory Identity，RNTI)进行区分；再例如，该终端设备也可以根据DCI中用于指示数据类型的指示信息直接确定下行数据的数据类型。
在另一种可能的实现方式中，该终端设备可以根据下行数据的属性确定下行数据的数据类型。例如，该终端设备可以通过承载下行数据的PDSCH的符号数确定下行数据的数据类型，假设，配置一个门限n，PDSCH的符号数大于n，则认为是eMBB数据，否则认为是URLLC数据。
这样，通过考虑第一下行数据和第二下行数据的优先级，在第二下行数据的优先级高于该第一下行数据的优先级以及该终端设备处理该第一下行数据的处理时段与处理该第二下行数据的处理时段部分重合的情况下，使得该终端设备不在网络设备调度的第三时间单元上发送该第一下行数据的反馈信息，而是优先处理该第二下行数据，降低了该第二下行数据的处理时延，提高了优先级较高的第二下行数据的传输性能。
方式2
在终端设备无法确定下行数据的数据类型的情况下，系统可以规定，在时间单元#2上发送的下行数据#2的优先级高于在时间单元#1上发送的下行数据#1的优先级。
在这种方式中，网络设备可以通过调度进行控制，使得终端设备在处理该下行数据#1的处理时段和在处理该下行数据#2的处理时段部分重合的情况下，在该时间单元#2上发送的该下行数据#2的优先级高于在该时间单元#1上发送的该下行数据#1的优先级。
具体而言，以eMBB数据和URLLC数据为例，考虑到eMBB数据对时延的要求通常不如URLLC数据对时延的要求高，当eMBB数据在URLLC数据之后到达时，网络设备可以通过调度，延迟发送eMBB数据以避免出现终端设备同时处理两种数据的情况；因此，只有当该下行数据#1为eMBB数据，该下行数据#2为URLLC数据时，由于URLLC数据不能延迟发送，所以，网络设备必须及时发送该下行数据#2，因此，才会出现该处理时段#1和该处理时段#2部分重合的情况。因此，系统可以规定：在出现处理时段部分重合的情况下，后面的时段到达的下行数据的优先级高于前面的时段到达的下行数据的优先级。
不过，需要说明的是，基于方式2的规则确定的两个下行数据的优先级可能并不是实际的下行数据的优先级。例如，若该下行数据#1的数据类型和下行数据#2的数据类型都是URLLC数据，网络设备都会及时发送这两种下行数据，基于方式2的规则，该终端设备会认为该下行数据#2的优先级高于该下行数据#1的，实际上，该下行数据#1的优先级和该下行数据#2的优先级是相同的。但是，从实现角度来说，这种方式易于实现。
作为示例而限定，上文所述的终端设备基于终端设备是否能够确定下行数据的数据类型的情况确定是否优先处理该下行数据#2的方式，仅为示意性说明，本申请实施例并不限于此。
例如，终端设备可以通过网络设备发送的DCI中用于指示下行数据的优先级的指示信息确定下行数据#1和下行数据#2的优先级，从而，基于下行数据的优先级确定是否优先处理下行数据#2。
以上，结合图5至图7，从下行传输的角度，详细描述了本申请一实施例的无线通信的方法200。下面，结合图8，从上行传输的角度，对本申请另一个实施例的无线通信的方法300做一详细说明。
在上行传输中，网络设备对发送上行数据之前，需要对上行数据做编码处理，处理完后发送上行数据。在一种通信场景中，终端设备在前后两个时段都需要发送上行数据，其中，终端设备对前后两个时段需要发送的上行数据的处理时段存在部分重合，也就是说，该终端设备对前个时段需要发送的上行数据的处理还未完成，就需要处理在下个时段需要发送的上行数据。但是，对于处理时段重合的情况，该终端设备可能无法同时处理两种数据，使得两种数据的传输都会受到影响。
因此，本申请实施例还提供了一种无线通信的方法，有助于提高上行数据传输的性能。
图8是本申请实施例提供的另一种无线通信的方法300的示意性交互图。下面，对方法300的每个步骤进行详细说明。
在S310中，网络设备发送DCI#A(即，第三DCI的一例)，该DCI#A包括指示信息#A(即，第三指示信息的一例)，该指示信息#A用于指示时间单元#A(即，第六时间单元的一例)，该时间单元#A用于承载上行数据#A(即，第一上行数据的一例)，其中，该上行数据#A的发送处理的处理时段#A(即，第三处理时段的一例)与上行数据#B(即，第二上行数据的一例)的发送处理的处理时段#D(即，第四处理时段的一例)部分重合，用于承载该上行数据#B的时间单元#B(即，第七时间单元的一例)位于该时间单元#A之后。
具体而言，该终端设备在前一个时段需要发送该上行数据#A，并且，可以通过基于授权的传输方式发送该上行数据#A，即，该网络设备通过DCI#A调度该终端设备在该时间单元#A上发送该上行数据#A；当该终端设备正在处理该上行数据#A的过程中，该终端设备又需要发送该上行数据#B，也会处理该上行数据#B。此种情况下，该终端设备处理该上行数据#A的处理时段#A会与处理该上行数据#B的处理时段#B部分重合。
其中，若该上行数据#B是基于授权的传输方式发送的数据，则该时间单元#B是网络设备通过DCI(例如，DCI#B)调度的资源；若该上行数据#B是基于免授权的传输方式发送的数据，则该时间单元#B是网络设备通过半静态方式配置的资源。
对于上行传输，在重合时段，该终端设备会需要更多的处理资源(例如，计算资源、 缓存数据的资源等)来处理两个上行数据，但是，该终端设备并没有足够的资源处理上行数据，这样情况可以认为是，该终端设备处理该上行数据#A的处理资源与该终端设备处理该上行数据#A的处理资源发生冲突。这样，会使得两个上行数据的处理都受到影响，该终端设备无法向该网络设备及时发送上行数据，影响了数据传输的可靠性。
为了解决该场景的问题，一种可能的实现方式是，在终端设备需要发送该上行数据#B的情况下，终端设备暂停处理上行数据#A，从而确保上行数据#B能够及时得到处理。由于终端设备暂停了对上行数据#A的处理，直到上行数据#B处理完成，从而导致终端设备无法及时在时间单元#A上发送数据#A，也就是说终端设备在时间单元#A上不发送上行数据#A。
进一步的，终端设备可以将发送上行数据#A的时间推迟到时间单元#C(即，第八时间单元的一例)，如S320所示。其中，时间单元#C在时间单元#A之后。
在一种可能的实现方式中，终端设备可以根据协议预定义的规则确定时间单元#C，例如，时间单元#C与时间单元#A之间可以间隔一个固定的时间长度，或者间隔一个网络设备给终端设备配置的时间长度。
对于网络设备来说，若是在该时间单元#A上未接收到该上行数据#A，则会调度资源通知该终端设备进行该上行数据#A的重传，即，通过DCI通知该终端设备在时间单元#C上重新发送该上行数据#A。因此，该终端设备可以在该时间单元#C上发送该上行数据#A。
对于上行数据#B来说，由于该终端设备暂停处理该上行数据A，该终端设备可以将资源预留出来用于处理后来需要发送的上行数据#B。
作为示例而非限定，该终端设备也可以对上行数据#A和上行数据#B做并行处理，但在具体实现过程中，会分配更多的处理资源用来处理上行数据#B。
若该上行数据#B是基于免授权的传输方式发送的数据，则该终端设备在处理完该上行数据#B后，可以通过预配置的免授权资源发送该上行数据#B。
若该上行数据是基于授权的传输方式发送的数据，在一种可能的实现方式中，
S311，网络设备发送DCI#B(即，第四DCI的一例)，该DCI#B包括指示信息#B(即，第四指示信息的一例)，该指示信息#B用于指示该时间单元#B；
S330，该终端设备在该时间单元#B上发送该上行数据#B。
也就是说，如前所述，该终端设备在该时间单元#A上不发送该上行数据#A的反馈信息，意味着该终端设备没有完成对该上行数据#A的处理，暂停了对该上行数据#A的处理，预留了处理资源来处理该上行数据#B，因此，该终端设备可以及时处理该上行数据#B，并且，处理完毕后可以在该网络设备的调度的时间单元#B上发送该上行数据#B。
因此，本申请实施例提供的无线通信的方法，在终端设备需要在第六时间单元需要发送第一上行数据和需要在位于该第六时间单元之后的第七时间单元上发送第二上行数据，并且，该第一上行数据的发送处理的处理时段和该第二上行数据的发送处理的处理时段部分重合的情况下，该终端设备不在该第六时间单元上发送该第一上行数据，而是在位于该第六时间单元之后的第八时间单元上发送该第一上行数据，可以使得该终端设备将未用来处理该第一上行数据的处理资源来处理该第二上行数据，提高了第二上行数据的传输性能。
考虑到在5G移动通信系统中如何更好地同时支持多种不同类型的数据的传输需求，同下行传输类似，该终端设备可以通过考虑上行数据的优先级确定是否优先处理该上行数 据#B。即，若该终端设备确定的该上行数据#B的优先级高于该上行数据#A的优先级，则该终端设备暂停处理该上行数据#A，优先处理该上行数据#B，执行方法200的技术方案；若该上行数据#B的优先级低于或等于该上行数据#A的优先级，则该终端设备继续处理该上行数据#A，延后处理该上行数据#B，使得该终端设备可以在网络设备调度的时间单元#A上发送该上行数据#A。
因此，在本申请实施例中，终端设备可以基于终端设备是否能够确定上行数据的数据类型的情况分别基于方式3和方式4确定是否优先处理该上行数据#B。
方式3
在终端设备可以确定上行数据的数据类型的情况下，根据该上行数据#A的数据类型和该上行数据#B的数据类型确定该上行数据#A和该上行数据#B的优先级，进而确定是否优先处理该上行数据#B。
若该上行数据#B的优先级高于该上行数据#A的优先级，则该终端设备暂停处理该上行数据#A，优先处理该上行数据#B，执行方法300的技术方案；若该上行数据#B的优先级低于或等于该上行数据#A的优先级，则该终端设备继续处理该上行数据#A，延后处理该上行数据#B。
其中，这里所说的上行数据的优先级可以从数据传输的时延、可靠性、传输速率等方面考虑来定义下行数据的优先级，具体描述可以参考上行传输中关于数据的优先级的描述，为了简洁，此处不再赘述。
在一种可能的实现方式中，该上行数据#A为eMBB数据，该上行数据#B为URLLC数据。
即，URLLC数据的优先级高于eMBB数据的优先级。
这里需要补充的是，若是该上行数据#A的数据类型和该上行数据#B的数据类型相同，数据的优先级可以进一步通过传输方式确定。
具体的，对于相同类型的业务数据，重传数据的优先级高于初传数据的优先级。对于URLLC业务的上行该数据传输，可能采用免授权的方式进行初传，而采用基于调度授权的方式进行重传。因此，在两种上行数据的数据类型相同的情况下，基于调度授权的传输方式发送的数据的优先级高于基于免授权的传输方式发送的数据的优先级。
在本申请实施例中，该终端设备确定上行数据的数据类型可以参考下行数据确定数据类型的方式，为了简洁，此处不再赘述。
这样，通过考虑第一上行数据和第二上行数据的优先级，在第二上行数据的优先级高于该第一上行数据的优先级以及该终端设备处理该第一上行数据的处理时段与处理该第二上行数据的处理时段部分重合的情况下，使得该终端设备优先处理第二上行数据，在第一时间单元上不发送第一上行该数据，从而提高了第二上行数据的传输性能。
方式4
在终端设备无法确定下行数据的数据类型的情况下，系统可以规定，将要在时间单元#B上发送的上行数据#B的优先级高于将要在时间单元#A上发送的上行数据#A的优先级；或者说，传输需求靠后的上行数据(即，上行数据#B)的优先级高于传输需求靠前的上行数据(即，上行数据#A)的优先级。
该方式4适用于该上行数据#A和该上行数据#B都是基于授权的传输方式发送的数据。 与下行传输的理由类似，网络设备可以做适当调控，使得终端设备在处理该上行数据#A的处理时段和在处理该上行数据#B的处理时段部分重合的情况下，传输需求靠后的上行数据(即，上行数据#B)的优先级高于传输需求靠前的上行数据(即，上行数据#A)的优先级。
具体而言，以eMBB数据和URLLC数据为例，考虑eMBB数据对时延的要求不高，当eMBB数据在URLLC数据之后到达时，网络设备可以使得调度的用于发送eMBB数据的时间单元延迟，以避免出现终端设备同时处理两种数据的情况；因此，只有当该上行数据#A为eMBB数据，该上行数据#B为URLLC数据时，由于URLLC数据不能延迟发送，所以，网络设备必须及时为该上行数据#B调度时间单元，以便于该终端设备可以在调度的时间单元上及时发送URLLC数据。因此，才会出现该处理时段#A和该处理时段#B部分重合的情况。因此，系统可以规定：在出现处理时段部分重合的情况下，传输需求靠后的上行数据的优先级高于传输需求靠前的上行数据的优先级。
不过，需要说明的是，基于方式4的规则确定的两个上行数据的优先级可能并不是实际的上行数据的优先级。具体描述可以参考方式2的相关描述，为了简洁，此处不再赘述。
需要补充的是，若上行数据#A的优先级高于上行数据#B的优先级，且上行数据#B是基于授权的传输方式发送的数据，该终端设备也可以不再处理该上行数据#B，该网络设备在调度的时间单元#B上接收不到该上行数据#B，会向该终端设备再发送一个DCI来重新调度发送上行数据#B的资源。
以上，结合图1至图8详细描述了本申请实施例提供的无线通信的方法，下面，结合图9至图12描述本申请实施例提供的无线通信的装置，方法实施例所描述的技术特征同样适用于以下装置实施例。
图9示出了本申请实施例提供的无线通信的装置400的示意性框图。如图9所示，该装置400包括：
接收单元410，用于接收第一下行控制信息DCI，该第一DCI包括第一指示信息，该第一指示信息用于指示在第三时间单元上发送第一下行数据的反馈信息；
该接收单元410还用于，在第一时间单元上接收第一下行数据；
该接收单元410还用于，在第二时间单元上接收第二下行数据，该第二时间单元位于该第一时间单元之后，该第一下行数据的接收处理的第一处理时段和该第二下行数据的接收处理的第二处理时段部分重合；
