网络设备与终端设备通信过程有时会出现乱序HARQ调度(out-of-HARQ order)。以网络设备向终端设备先后发送第一物理上行共享信道(physical downlink shared channel，PDSCH)和第二PDSCH为例，如果第二PDSCH中的数据属于紧急业务对应的数据，则网络设备可能会对第一PDSCH和第二PDSCH进行调度，使得终端设备优先反馈第二PDSCH的HARQ信息，此时，第一PDSCH和第二PDSCH的调度方式即为一种乱序HARQ调度。
网络设备基于HARQ机制能够获知终端设备是否正确接收PDSCH对应的数据，但在乱序HARQ调度场景中，仅获知PDSCH对应的数据的接收状态不利于网络设备做出正确的调度策略。

下面以网络设备和终端设备为例，对PDSCH的调度过程进行详细描述。
HARQ重传技术是将前向纠错(forward error correction，FEC)与自动重传请求(automatic repeat-request，ARQ)结合起来，提升通信的额可靠性。网络设备向终端设备发送数据包时，数据包经过物理层的FEC编码、调制后送到天线端口传输出去。数据包到达终端设备后，经过终端设备的物理层进行解调、解码，并将解码结果反馈给发送端。通常，网络设备是根据终端设备反馈的HARQ信息确定数据有没有被正确接收。如果终端设备能够正确接收到该数据包，则向网络设备发送确认(acknowledgement，ACK)信息，如果终端设备不能正确接收到该数据包，则向网络设备发送非确认(negative acknowledgement，NACK)信息。网络设备接收到终端设备发送的NACK后，则重新发送该数据包。
一般来讲，网络设备调度终端设备接收第一PDSCH和第二PDSCH，为方便描述，下文将第一PDSCH和第二PDSCH简称为D1和D2。假设D1在D2之前调度和传输，正常情况下，D2的HARQ信息的反馈时间不早于D1的HARQ信息的反馈时间，这种调度称为顺序调度。但在某些场景下，例如D2为紧急业务，这时网络设备可能会调度D2的HARQ 信息的反馈时间提前于D1的HARQ信息的反馈时间，这种后调度的数据先反馈的情况，称为乱序HARQ调度。
网络设备基于HARQ机制能够获知终端设备是否正确接收PDSCH对应的数据，但在乱序HARQ调度场景中，仅获知PDSCH对应的数据的接收状态不利于网络设备做出正确的调度策略。
本申请实施例提供一种无线通信方法，有利于网络设备在乱序HARQ调度场景下做出正确的调度策略。
图2是本申请实施例提供的一种无线通信方法的示意性流程图。图2的方法包括步骤210-230，下面分别对步骤210-230进行详细描述。
在步骤210中，网络设备向终端设备发送第一PDSCH和第二PDSCH，其中，第一PDSCH的发送时间早于第二PDSCH的发送时间，第一PDSCH对应的HARQ信息的接收时间晚于第二PDSCH的HARQ信息的接收时间。也就是说，网络设备对第一PDSCH和第二PDSCH的调度为乱序HARQ调度。
网络设备可以为具有无线资源调度功能。网络设备例如可以为基站、小区或具有调度功能的其他类型的网络节点和中继节点，网络设备还可以是具有调度功能的中继终端。在某些实施例中，网络设备也可以是芯片系统。
在步骤220中，网络设备确定第二PDSCH的传输是否会导致终端设备对第一PDSCH的处理过程被中断。
终端设备对第一PDSCH的处理过程可以包括以下过程中的至少一种：第一PDSCH对应的数据的接收过程，第一PDSCH的解调过程以及第一PDSCH的解码过程。
在步骤230中，如果网络设备确定第二PDSCH的传输会导致所述终端设备对所述第一PDSCH的处理过程被中断，则网络设备确定第一PDSCH所对应的第一数据未被成功接收。
根据本申请实施例提供的方法，在乱序HARQ调度场景下，网络设备主动判断第二PDSCH的传输是否会引起在先传输的第一PDSCH的处理过程被中断，有利于网络设备做出正确的调度策略。
为方便描述，下文将第一PDSCH和第二PDSCH简称为D1和D2进行描述。
通常，如果终端设备在处理D1的数据的过程中，发现需要处理更为紧急的数据D2，则终端设备会中断D1的处理，转而进行D2的处理。由于D1的处理被中断，D1的数据可能没有被完全接收，所以终端设备会向网络设备反馈D1的HARQ信息为NACK。网络设备根据终端设备反馈的NACK信息，向终端设备发送重传数据。
本申请实施例中，网络设备向终端设备调度D1和D2，可以是向终端设备同时发送D1和D2，也可以是向终端设备先后发送D1和D2。
增量冗余(incremental redundancy，IR)是HARQ重传技术的一种，IR技术是通过在第一次传输时发送信息位(bit)和一部分冗余bit，而通过重传(retransmission)发送额外的冗余bit。如果第一次传输没有成功解码，则可以通过重传更多冗余bit降低信道编码率，从而提高解码成功率。如果加上重传的冗余bit仍然无法正常解码，则进行再次重传。随着重传次数的增加，冗余bit不断积累，信道编码率不断降低，从而可以获得更好的解码效果。通常情况下，第一次传输的数据包是可以独立译码的，但重传数据包则可能会只传 输较少的冗余比特，单独用重传数据包是无法独立译码的。
但如果网络设备不知道终端设备是由于D1的中断而反馈的NACK，网络设备发送的重传数据包可能是无法自译码的数据包。这样，终端接收到这个重传数据包后，无法正确译码，会继续反馈NACK，从而网络设备继续重传，这个过程一直持续到重传次数到达一定的次数，而启动高层数据重传或者丢弃数据。在乱序HARQ调度场景下，采用增量冗余重传技术会导致数据丢失，数据传输时延增加，传输资源浪费等。
根据本申请实施例提供的无线通信方法，网络设备在主动地确定D1由于被中断而没有正确接收后，可以根据这个预判，做出一些合理的决策，从而能够避免不必要的重传，减少传输资源的浪费以及传输时延的增加。
可选地，作为一个示例，网络设备确定终端设备会中断D1后，可以选择丢掉D1的传输数据，重新调度D1，向终端设备发送D1的初始传输数据。
可选地，作为一个示例，网络设备确定终端设备会中断D1后，向终端设备发送D1的第一重传数据，其中，第一重传数据为能够独立译码的重传数据。这样可以避免终端设备接收到不能独立译码的数据包而不能正确译码，会继续反馈NACK，导致传输时延增加，传输资源浪费的问题。
可选地，作为一个示例，网络设备确定终端设备会中断D1后，可以选择不接收D1的HARQ信息，也就是说，不接收D1的ACK/NACK的反馈信息，直接按照D1的HARQ信息为NACK进行处理，向终端设备发送第一重传数据。这样，能够节省网络设备接收D1的HARQ的资源，从而能够减少传输功率。
网络设备不接收D1的HARQ信息，可以指终端设备在预定时间上不发送HARQ信息，或者终端设备可以发送HARQ信息，但网络设备在预定时间不去接收该HARQ信息。
可选地，作为一个示例，如果网络设备确定终端设备会中断D1后，可以选择在目标时间向终端设备发送第一重传数据，其中，目标时间不晚于D1对应的HARQ信息的接收时间。也就是说，网络设备提前向终端设备发送第一重传数据，从而能够减少传输时延。
可选地，作为一个示例，网络设备确定D1所对应的第一数据未被成功接收后，向终端设备发送第一重传数据。其中，第一重传数据为能够独立译码的重传数据。作为一个示例，第一重传数据为与D1对应的初始传输数据包相同的数据。
进一步地，网络设备可以确定本次调度的是否为D1的初始传输数据，如果是初始传输数据，则网络设备向终端设备发送可独立译码的重传数据。如果是不是初始传输数据，也就是说，如果本次调度的是重传数据包，网络设备可以向终端设备发送第一重传数据，或者也可以按照正常的重传流程就行重新调度，向终端设备发送重传数据(如增量冗余数据)。
本申请实施例对网络设备确定D2的传输是否会导致终端设备对D1的处理过程被中断的确定方式不做具体限定。作为一个示例，网络设备根据终端设备的能力信息，及D1所对应的传输方式和D2所对应的传输方式，确定D2的传输是否会导致终端设备对D1的处理过程被中断。
可选地，D1所对应的传输方式包括：D1的结束位置，D1的最后一个解调参考信号(demodulation reference signal，DMRS)的结束位置，D1所对应的HARQ信息的开始传输位置，D1的子载波间隔。D2所对应的传输方式包括：D2的结束位置，D2的最后一个 DMRS的结束位置，D2所对应的HARQ信息的开始传输位置，D2的子载波间隔。
本申请实施例对能力信息的获取方式不做具体限定。作为一个示例，能力信息可以是网络设备根据协议上的规定获得的。作为另一个示例，能力信息可以是终端设备向网络设备上报的能力信息。
本申请实施例中，能力信息可以包括以下信息中的至少一种：终端设备的下行数据处理时延、终端设备能够同时处理的PDSCH的数量。
其中，终端设备的下行数据处理时延，指终端设备从一个PDSCH的最后一个正交频分复用技术(orthogonal frequency division multiplexing，OFDM)符号接收结束开始到对应该PDSCH的HARQ信息的最早可能发送开始时间的时间间隔。其中，HARQ信息包括终端设备反馈的ACK/NACK信息。一般情况下，终端设备从一个PDSCH的最后一个OFDM符号接收结束到发送ACK/NACK信号的开始时间的时间间隔，要大于等于终端设备的下行数据处理时延。
终端设备的下行数据处理时延大小，包括终端设备在不同调度条件下的处理时延大小。调度条件包括以下条件中的至少一种：PDSCH的子载波间隔；PDSCH的DMRS，例如PDSCH只有前置解调参考信号，或者PDSCH除了包括前置解调参考信号外，还包括额外的参考信号；传输的数据是初始传输数据还是重传数据；PDSCH的类型，PDSCH的类型例如可以为type A或者type B，其中，TYPE A的PDSCH的时域长度大于等于7OFDM符号，TYPE B的PDSCH的时域长度小于7OFDM符号；PDSCH的资源映射方式，例如PDSCH的资源映射方式是先时域后频域映射，或者是先频域后时域映射。
以PDSCH的子载波间隔和DMRS为例，对不同调度条件下的下行数据处理时延大小进行举例说明。
如果用OFDM符号来表示下行数据处理时延，则可将下行数据处理时延表示为N1个OFDM符号，其中，N1为正整数(N1：从终端设备的角度来看，从NR-PDSCH接收结束到相应的ACK/NACK最早可能开始传输时间，定义为终端设备进行处理所需的OFDM符号数)。不同调度条件下的下行数据处理时延大小如下表1所示。
表1
Figure PCTCN2019074879-appb-000001
网络设备要调度PDSCH所对应的ACK/NACK的传输时间，要大于等于(N1+TA)符号。TA表示定时提前量(timing advanced)，例如可以指终端设备相对于下行传输的上行定时提前量。TA可以符号为单位进行计量，也可以绝对时间或者以采样率为单位计量，我们这里统一以符号为单位计量。
若PDSCH在第N个时隙传输，且PDSCH的最后一个OFDM符号是N时隙的X_2符号，对应的ACK/NACK在(N+K1)时隙的X_3符号传输，则K1*L+(X_3-TA)-X_2大于 等于N1。其中，L表示一个时隙中的符号数，例如L＝14或者L＝7。
终端设备能够同时处理的PDSCH的数量，可以为终端在不同传输条件下，能够同时处理的PDSCH的数量。
在不同传输条件下，终端设备能够同时处理的PDSCH的数量，可以包括以下信息中的至少一种：每个载波上能够同时处理的PDSCH的数量；每个频带band能够同时处理的PDSCH的数量；高频或者低频能够同时处理的PDSCH的数量；终端设备总的能够同时处理的PDSCH数量；终端设备能够同时处理不同大小的PDSCH的数量。例如，对于大于100k的数据包，终端设备能够同时处理1个PDSCH；对于小于等于100k的数据包，终端设备可以同时处理2个PDSCH。
在本申请实施例中，PDSCH例如可以为单播PDSCH，也可以为组播PDSCH，也可以为广播PDSCH。终端设备能够同时处理的PDSCH的数量，例如可以是每个载波上能够同时处理的单播PDSCH的数量，或者是每个载波上能够同时处理的单播或广播PDSCH的数量，本申请对此不做具体限定。
本申请实施例对网络设备确定D2的传输是否会导致终端设备对所述D1的处理过程被中断的方式不做具体限定。作为一个示例，网络设备可以根据D2的反馈时间与D1的反馈时间的符号差来确定。作为另一个示例，可以根据D2的最晚开始处理时间是否早于D1的处理结束时间来确定。换句话说，可以根据D1的处理时间是否晚于D2的最早开始处理时间来确定。如果终端设备在每个载波上能够同时处理的单播PDSCH的数量有限，例如为1，且如果D2的最晚开始处理时间早于D1的处理结束时间，则网络设备可以确定来自终端设备的反馈信号不会是ACK。
本申请实施例对确定D1的处理时间是否晚于D2的最早开始处理时间的方式不做具体限定。作为一个示例，可以按照下述方法确定D2的最晚开始处理时间是否晚于D1的处理结束时间。
判断方法如下，以D1的第一个符号作为符号0，之后的符号顺序编号。
1)D1的最后一个承载DMRS的符号为符号X1_1；
2)D1的最后一个数据的符号为符号X1_2；
3)传输D1所对应的ACK/NACK的第一个符号为符号X1_3；
4)D1的处理时延为N1_1符号；
5)D1的子载波间隔为S_1；
6)D2的最后一个承载DMRS的符号为符号X2_1；
7)D2的最后一个数据的符号为符号X2_2；
8)传输D2所对应的ACK/NACK的第一个符号为符号X2_3；
9)D1的处理时延为N1_2符号；
10)D2的子载波间隔为S_2；
11)如果(X2_3-TA-(X2_2-X2_1+N1_2))/S_2>(X1_1+(X1_2-X1_1+N1_1))/S_1，则认为D2的最晚开始处理时间早于D1的处理结束时间。
如果D2的最晚开始处理时间早于D1的处理结束时间，进一步地，如果D1是初始传输数据，则网络设备向终端设备重新发送初始传输数据或能够自译码的数据。如果D1是重传数据，则网络设备可以向终端设备发送初始传输数据或能够自译码的数据，也可以按 照正常的重传流程进行重新调度，发送增量冗余数据。
可选地，作为一个示例，如果D2的最晚开始处理时间晚于D1的处理结束时间，且D1对应的HARQ信息为NACK，则网络设备向终端设备发送D1对应的第二重传数据，第二重传数据为D1对应的增量冗余数据。
下面结合图3，对D2的处理是否会导致D1的处理过程被中断的情况进行具体说明。在图3中，N1_1’＝N1_1+(X1_2-X1_1)，N1_2’＝N1_2+(X2_2-X2_1)。
情况1：D2的处理会造成D1的处理过程被中断。D2的最晚开始处理时间早于D1的处理结束时间，也就是说，D1的处理结束时间到D2反馈ACK/NACK的时间小于处理D2所需要的时间。因此，D2的处理会导致D1的处理过程被中断。
情况2：D2的处理不会造成D1的处理过程被中断。D2的最晚开始处理时间晚于D1的处理结束时间，也就是说，D1的处理结束时间到D2反馈ACK/NACK的时间大于处理D2所需要的时间。因此，D2的处理不会导致D1的处理过程被中断。
可选地，作为一个示例，网络设备在调度D1和D2的过程中，可以采取措施避免出现乱序HARQ调度。
可选地，网络设备在确定终端设备对D2的处理会导致D1的处理被中断后，可以选择通知终端设备是丢弃D1还是D2。作为一个示例，网络设备可以预先确定终端设备的能力信息，在终端设备处理能力受限的情况下，确定是在先调度的D1的优先级更高还是在后调度的D2的优先级更高。如果在先调度的D1的优先级高，则向终端设备发送配置信息，以指示终端设备优先处理D1的数据，只有在D1的数据处理完成后才会处理D2的数据。
可选地，网络设备可以根据终端设备的能力，确定D2的传输方式。例如网络设备可以为D2的反馈预留足够的时间避免发生中断的场景。例如，如果网络设备确定D2为非紧急业务，则可以确定D2的传输方式，使得D2的最晚开始时间晚于D1的处理结束时间。其中，网络设备可以根据上文描述的方法确定为D2的反馈预留的时间是否足够。例如X2_3>X1_1+(X1_2-X1_1+N1_1)+TA+(X2_2-X2_1+N1_2)。
可选地，网络设备可以采取下述简化的条件确定D2是否会中断D1。
1)如果D1和D2的调度条件相同，则网络设备可以默认D1不会被中断。
2)如果D1和D2的调度时间间隔很长，则网络设备可以默认D1不会被中断。
3)如果D1和D2为连续调度，且调度条件发生变化，且D1的处理时间大于D2的处理时间，则网络设备可以默认D1会被中断。
图4是本申请实施例提供的另一种无线通信方法的示意性流程图。图4的方法包括步骤410-430，下面分别对步骤410-430进行详细描述。
在步骤410中，终端设备从网络设备接收第一PDSCH和第二PDSCH，其中第一PDSCH的接收时间早于第二PDSCH的接收时间，第一PDSCH对应的HARQ信息的发送时间晚于所述第二PDSCH的HARQ信息的发送时间。
在步骤420中，终端设备确定第二PDSCH的传输是否会导致终端设备对第一PDSCH的处理过程被中断。
在步骤430中，如果终端设备确定第二PDSCH的传输会导致终端设备对第一PDSCH的处理过程被中断，终端设备中断第一PDSCH所对应的第一数据的处理。
根据本申请提供的无线通信方法，在乱序HARQ调度场景下，终端设备主动判断第二PDSCH的传输是否会引起在先传输的第一PDSCH的处理过程被中断，有利于终端设备做出正确的调度策略。
网络设备根据第一PDSCH和第二PDSCH的调度方式，主动地去判断第二PDSCH的传输是否会造成第一PDSCH的处理过程被中断，以确定第一PDSCH是否成功接收，使得通信方式更加灵活。
可选地，终端设备可以接收网络设备发送的第一重传数据或新的第一PDSCH，该第一重传数据为能够独立译码的重传数据。其中，第一重传数据可以为与第一PDSCH对应的初始传输数据相同的数据。
可选地，终端设备确定中断第一PDSCH后，可以选择丢弃本次调度的第一PDSCH，从而来节省资源。然后再接收网络设备发送的第一重传数据进行解调解码等操作。
可选地，终端设备可以根据自己的能力信息，可以选择在中断第一PDSCH后，存储中断第一PDSCH时的状态，在第二PDSCH处理结束后继续进行第一PDSCH的处理。
可选地，终端设备确定中断第一PDSCH后，可以确定对应于第一PDSCH的HARQ信息为NACK信息，进而在对应于第一PDSCH的HARQ信息传输资源上传输该NACK信息。
可选地，终端设备确定中断第一PDSCH后，可以选择不发送对应于第一PDSCH的ACK/NACK信号，以节省传输资源。
本申请实施例对终端设备确定第二PDSCH的传输是否会导致终端设备对第一PDSCH的处理过程被中断的确定方式不做具体限定。作为一个示例，终端设备根据终端设备的能力信息，及第一PDSCH所对应的传输方式和第二PDSCH所对应的传输方式，确定第二PDSCH的传输是否会导致终端设备对第一PDSCH的处理过程被中断。
根据本申请实施例提供的无线通信方法，终端设备在处理在先调度的第一PDSCH时，接收到在后的第二PDSCH的调度信令。如果出现乱序HARQ调度，则终端设备判断终端设备是否由于接收在后调度的更紧急反馈的数据第二PDSCH而中断在先调度的数据第一PDSCH的处理。如果是，则中断D1的处理；如果不需要中断，则缓存D2的数据等待D1数据处理结束后进行D2的处理。
可选地，终端设备也可以向网络设备发送自己的能力信息。
可选地，第一PDSCH所对应的传输方式包括以下信息中的至少一种：第一PDSCH的结束位置，第一PDSCH的最后一个DMRS的结束位置，第一PDSCH所对应的HARQ信息的开始传输位置，第一PDSCH的子载波间隔。第二PDSCH所对应的传输方式包括以下信息中的至少一种：第二PDSCH的结束位置，第二PDSCH的最后一个DMRS的结束位置，第二PDSCH所对应的HARQ信息的开始传输位置，第二PDSCH的子载波间隔。
本申请实施例中，能力信息可以包括以下信息中的至少一种：终端设备的下行数据处理时延、终端设备能够同时处理的PDSCH的数量。
其中，终端设备的下行数据处理时延，指终端设备从一个PDSCH的最后一个OFDM符号接收结束开始到对应该PDSCH的HARQ信息的生成时间。其中，HARQ信息包括终端设备反馈的ACK/NACK信息。一般情况下，终端设备从一个PDSCH的最后一个OFDM符号接收结束到发送ACK/NACK信号的时间间隔，要大于等于终端设备的下行数据处理 时延。
终端设备的下行数据处理时延大小，包括终端设备在不同调度条件下的处理时延大小。该调度条件包括以下条件中的至少一种：PDSCH的子载波间隔；PDSCH的DMRS，例如PDSCH只有解调参考信号，或者PDSCH还包括额外的参考信号；传输的数据是初始传输数据还是重传数据；PDSCH的类型。例如PDSCH的类型可以为type A或者type B，其中，TYPE A的PDSCH的时域长度大于等于7OFDM符号，TYPE B的PDSCH的时域长度小于7OFDM符号。
以PDSCH的子载波间隔和DMRS为例，对不同调度条件下的下行数据处理时延大小进行举例说明。
如果用OFDM符号来表示下行数据处理时延，则可将下行数据处理时延表示为N1个OFDM符号，其中，N1为正整数。不同调度条件下的下行数据处理时延大小如下文表1所示。
终端设备从接收PDSCH结束开始到开始传输ACK/NACK的时间，要大于等于(N1+TA)符号。TA表示timing advanced，定时提前量，TA为m个符号，m为正整数。TA指终端设备相对于下行传输的上行定时提前量。
若PDSCH在第N个时隙传输，且PDSCH的最后一个符号是X_2，对应的ACK/NACK在(N+K1)时隙的X_3符号传输，则K1*L+(X_3-TA)-X_2大于等于N1。其中，L表示一个时隙中的符号数，L＝7或14或者其他值。
终端设备能够同时处理的PDSCH的数量，可以为终端在不同传输条件下，能够同时处理的PDSCH的数量。
在不同传输条件下，终端设备能够同时处理的PDSCH的数量，包括以下信息终端的至少一种：每个载波上能够同时处理的PDSCH的数量；每个频带band能够同时处理的PDSCH的数量；高频或者低频能够同时处理的PDSCH的数量；终端设备总的能够同时处理的PDSCH数量；终端设备能够同时处理不同大小的PDSCH的数量。例如，对于大于100k的数据包，终端设备能够同时处理1个PDSCH；对于小于等于100k的数据包，终端设备可以同时处理2个PDSCH。
在本申请实施例中，PDSCH例如可以为单播PDSCH，也可以为组播PDSCH，本申请对此不做具体限定。
本申请实施例对终端设备确定第二PDSCH的传输是否会导致所述终端设备对第一PDSCH的处理过程被中断的方式不做具体限定。作为一个示例，终端设备可以根据第二PDSCH的反馈时间与第一PDSCH的反馈时间的符号差来确定。作为另一个示例，终端设备可以根据第二PDSCH的最晚开始处理时间是否早于第一PDSCH的处理结束时间来确定。换句话说，终端设备可以根据第一PDSCH的处理结束时间是否晚于第二PDSCH的最早开始处理时间来确定。如果第二PDSCH的最晚开始处理时间早于第一PDSCH的处理结束时间，则终端设备可以确定中断第一PDSCH的处理。作为另一个示例，终端设备可以根据终端设备的PDSCH处理能力，以及第二PDSCH的最晚开始处理时间是否早于第一PDSCH的处理结束时间来确定。若终端设备能够同时处理的单播PDSCH的数量有限，例如为1，且如果第二PDSCH的最晚开始处理时间早于第一PDSCH的处理结束时间，则终端设备可以确定中断第一PDSCH处理。
本申请实施例对确定第一PDSCH的处理结束时间是否晚于第二PDSCH的最早开始处理时间的方式不做具体限定。作为一个示例，可以按照下述方法确定第二PDSCH的最晚开始处理时间是否晚于第一PDSCH的处理结束时间。为方便描述，下文将第一PDSCH和第二PDSCH简称为D1和D2。
判断方法如下，以D1的第一个符号作为符号0，之后的符号顺序编号。
1)D1的最后一个承载DMRS的符号为符号X1_1；
2)D1的最后一个数据的符号为符号X1_2；
3)传输D1所对应的ACK/NACK的第一个符号为符号X1_3；
4)D1的处理时延为N1_1符号；
5)D1的子载波间隔为S_1；
6)D2的最后一个承载DMRS的符号为符号X2_1；
7)D2的最后一个数据的符号为符号X2_2；
8)传输D2所对应的ACK/NACK的第一个符号为符号X2_3；
9)D1的处理时延为N1_2符号；
10)D2的子载波间隔为S_2；
11)如果(X2_3-TA-(X2_2-X2_1+N1_2))/S_2>(X1_1+(X1_2-X1_1+N1_1))/S_1，则认为D2的最晚开始处理时间早于D1的处理结束时间。
传统的通信方式中，通常采用PDSCH来承载网络设备发送给终端设备的数据信息，采用物理下行控制信道(physical downlink control channel，PDCCH)来承载网络设备发送给终端设备的控制信令，采用物理上行控制信道(physical uplink control channel，PUCCH)或者物理上行共享信道(physical uplink shared channel，PUSCH)来承载针对PDSCH承载的数据是否成功接收的确认信号ACK/NACK。
本申请实施例中，网络设备(如基站或小区)确定下行数据的传输方式以及针对该下行数据的反馈信号承载的资源，并通过下行控制信令传送给终端设备，所述下行数据的传输方式，包括下行数据的时频资源、调制方式、编码方式、资源映射方式等，所述针对该下行数据的反馈信号的承载资源，包括该反馈信号ACK/NACK的时频资源。ACK/NACK的时频资源，可以是通过网络设备发送的控制信令中直接指定的，也可以是按照一定的规则获得的，或者是部分资源信息是通过控制信令指定，部分资源信息是按照预定义的规则获得的。终端设备首先接收下行控制信令，从而获得需要自己接收的PDSCH的传输方式，然后按照所定义的传输方式，接收相应的PDSCH，并译码在所述PDSCH上承载的数据块或传输块(transmission block，TB)，并根据译码结果，生成相应的ACK或者NACK信号，然后根据所确定的ACK/NACK传输方式在ACK/NACK的传输资源上传输对应的ACK/NACK信号。终端设备接收PDSCH到发送ACK/NACK之间的时间间隔，要大于等于终端设备处理该PDSCH数据的处理时延。
