Description

通信方法及装置 技术领域
本申请涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
第五代(5th generation，5G)移动通信系统与前几代移动通信系统相比，对数据传输速率、数据传输可靠性、传输时延以及功耗的要求更高。以5G的超可靠低延迟通信(ultra-reliable and low-latency communication，URLLC)业务为例，该业务的需求包括：数据传输可靠性达到99.999％，传输时延低于1毫秒(milisecond，ms)，以及尽可能减小指令开销。因此，如何提高数据传输可靠性，降低传输时延，以及降低信令开销，从而降低功耗，成为亟需解决的问题。
目前，可以通过半静态调度(semi-persistent scheduling，SPS)物理下行共享信道(physical downlink shared channel，PDSCH)传输数据，但是半静态调度物理下行共享信道(下文简称为SPS PDSCH)对应的反馈信息可能被取消(drop)发送，网络设备不知道SPS PDSCH是否接收成功。因此，若网络设备直接重传SPS PDSCH，则会浪费资源，导致传输效率低下，若网络设备不重传SPS PDSCH，则又会导致数据丢失，数据传输可靠性低下。
发明内容
本申请实施例提供一种通信方法及装置，能够解决SPS PDSCH数据传输可靠性低，传输效率低的问题，以提高通信效率。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种通信方法。该通信方法可以应用于终端设备，该通信方法包括：确定第一上行资源。其中，第一上行资源位于第一时间单元，且承载第一反馈信息，第一反馈信息为半静态调度物理下行共享信道对应的反馈信息。若第一上行资源所占用的时域符号(symbol)包括：下行符号(downlink symbol)，和/或，未指示用于上行传输的灵活符号(flexible symbol)，则确定第二时间单元和第二上行资源。其中，第二上行资源位于第二时间单元内，第二上行资源所占用的时域符号均为用于上行传输的符号，且第二上行资源的时域起始位置位于第一上行资源的时域起始位置之后。在第二上行资源上发送第一反馈信息。
基于第一方面所述的通信方法，若第一上行资源被取消发送，例如第一上行资源所占用的时域符号包括：下行符号，和/或，未指示用于上行传输的灵活符号，则终端设备可以在第一上行资源的时域起始位置之后的资源中，确定第二时间单元和第二上行资源，并在第二上行资源上发送第一反馈信息。如此，SPS PDSCH对应的反馈信息在第一上行资源不被发送时，终端设备可以将反馈信息延后至第二上行资源发送。如此，网络设备可以根据该反馈信息确定SPS PDSCH是否接收成功，并确定是否重传数据，以减少数据丢失的概率，提高数据传输可靠性，且可以降低数据重传的次数，节省资源，提高传输效率，进而提高通信效率。
一种可能的设计方案中，第二时间单元可以位于第一时间单元之后，或者，第二时间单元和第一时间单元可以为同一时间单元。如此，终端设备既可以在第一时间单元发送第一反馈信息，也可以在第一时间单元之后的时间单元发送第一反馈信息，可以提高终端设备发送第一反馈信息的灵活性。
可选地(下文简称为方式1)，第二上行资源在第二时间单元中的相对位置与第一上行资源在第一时间单元中的相对位置可以相同。这样，存在第二上行资源的时域范围，可以从第一上行资源的时域起始位置之后的所有时域，缩小到第一上行资源的时域起始位置之后的每个时间单元中的部分符号，也即是说，终端设备可以在较小的时域范围确定第二时间单元和第二上行资源，从而能够减少终端设备的计算量，节省功耗。
或者，可选地(下文简称为方式2)，第二上行资源的时域宽度与第一上行资源的时域宽度可以相等，和/或，第二上行资源的频域宽度与第一上行资源的频域宽度可以相等。换句话说，第二上行资源的大小等于第一上行资源的大小。这样，存在第二上行资源的时域范围，可以从第一上行资源的时域起始位置之后的所有时域，缩小到第一上行资源的时域起始位置之后的部分时域，该部分时域为包括可用上行资源的时域，该可用上行资源的大小可以与第一上行资源的大小相等，也即是说，终端设备可以在较小的时域范围确定第二时间单元和第二上行资源，从而能够减少终端设备的计算量，节省功耗。
上述的方式1、方式2可以独立实施，也可以结合实施。方式1与方式2结合实施的方式可以包括：第二上行资源在第二时间单元中的相对位置与第一上行资源在第一时间单元中的相对位置相同，且第二上行资源的时域宽度与第一上行资源的时域宽度相等，和/或，第二上行资源的频域宽度与第一上行资源的频域宽度相等。这样，存在第二上行资源的时域范围，可以从第一上行资源的时域起始位置之后的所有时域，缩小至上述部分时域的每个时间单元中的部分符号，也即是说，终端设备可以在更小的时域范围确定第二时间单元和第二上行资源，从而能够减少终端设备的计算量，节省功耗。
一种可能的设计方案中，上述的确定第二时间单元和第二上行资源，可以包括：确定第二时间单元。其中，第二时间单元可以为一个或多个候选时间单元中时域位置最靠前的候选时间单元，每个候选时间单元的时域起始位置可以均不早于第一时间单元的时域起始位置，且每个候选时间单元可以均满足：第一条件，和/或，第二条件。其中，第一条件可以为：存在可用SPS反馈资源，可用SPS反馈资源的时域符号均为用于上行传输的符号，且可用SPS反馈资源对应的码本比特区间的最大值可以大于或等于反馈比特数，反馈比特数可以为候选时间单元中的SPS反馈信息的码本比特数与第一反馈信息的码本比特数之和。第二条件可以为：存在上行信号，上行信号可以包括上行数据或动态反馈信息。在第二时间单元中确定第二上行资源。这样，终端设备在第二时间单元中确定第二上行资源时，可以通过时间单元中已存在的可用SPS反馈资源承载第一反馈信息，或者通过时间单元中已存在的承载上行信号的资源承载第一反馈信息，也即是说，可以用一个反馈资源承载多个反馈信息，从而可以减少终端设备与网络设备的交互次数，降低信令开销，以提高通信效率。
可选地，上述的在第二时间单元中确定第二上行资源，可以包括：若第二时间单元满足第一条件且不满足第二条件，则确定第二时间单元中的可用SPS反馈资源为第二上行资源。或者，若第二时间单元满足第二条件，则确定第二时间单元中承载上行信号的资源为第二上行资源。这样，可以优先通过时间单元中已存在的承载上行信号的资源承载第一反馈信息，由于承载上行信号的资源可以为动态反馈资源(如动态调度的PDSCH对应的反馈资源)，且相较于可用SPS反馈资源，动态反馈资源所占用的信道的质量往往更好，反馈成功率更高，因此优先通过承载上行信号的资源承载第一反馈信息，能够提高数据传输可靠性，降低传输时延，以提高通信效率。

具体实施方式
首先，本申请实施例对可能涉及的技术术语作简单介绍。
1，时隙(slot)
5G的新空口(new radio，NR)中存在多种时间单元，包括：帧(frame)、子帧(subframe)、时隙和符号(symbol)。一个帧的时间长度为10毫秒(milisecond，ms)， 包括10个子帧，每个子帧的时间长度可以为1ms，一个子帧可以包括一个或多个时隙。一个时隙在扩展循环前缀(extended cyclic prefix，ECP)情况下包括12个符号，在普通循环前缀(normal cyclic prefix，NCP)情况下包括14个符号。其中，符号被分为：上行符号(uplink symbol)、下行符号(downlink symbol)以及灵活符号(flexible symbol)。这里的符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。
NR支持灵活地配置帧结构，即可以灵活地配置一个时隙中，哪些符号为上行符号，哪些符号为下行符号，哪些符号为灵活符号。配置的方式可以包括：半静态(semi-persistent scheduling，SPS)配置或动态(dynamic)配置。其中，在半静态配置方式中，上行符号被称为半静态上行符号，下行符号被称为半静态下行符号，灵活符号被称为半静态灵活符号。在动态配置方式中，上行符号被称为动态上行符号，下行符号被称为动态下行符号，灵活符号被称为动态灵活符号。另外，半静态配置和动态配置的具体实现过程可以参考现有技术规定，在此不再赘述。
灵活符号可以被修改为上行符号或下行符号，被修改为上行符号的灵活符号可以称为指示用于上行传输的灵活符号，被修改为下行符号的灵活符号可以称为指示用于下行传输的灵活符号。其中，灵活符号被修改为上行符号或下行符号的具体实现过程可以参考现有技术规定，在此不再赘述。
上行符号或指示用于上行传输的灵活符号可以进行上行传输，下行符号或指示用于下行传输的灵活符号可以进行下行传输。换句话说，在下行符号，和/或，未指示用于上行传输的灵活符号不能用于上行传输。其中，未指示用于上行传输的灵活符号包括：动态灵活符号、半静态灵活符号以及指示用于下行传输的灵活符号。
2，SPS PDSCH
网络设备与终端设备之间可以通过SPS PDSCH传输数据，具体步骤如下：
步骤1，网络设备向终端设备发送配置信息，终端设备接收来自网络设备的配置信息。
其中，该配置信息用于指示：SPS PDSCH的传输周期以及承载SPS PDSCH对应的反馈信息的资源等。这里的SPS PDSCH对应的反馈信息是指SPS PDSCH的肯定应答(acknowledge，ACK)信息或者否定应答(non-acknowledge，NACK)信息，SPS PDSCH对应的反馈信息可以包含于混合自动重传请求(hybrid automatic repeat request acknowledgement，HARQ-ACK)码本中。承载SPS PDSCH对应的反馈信息的资源，可以是物理上行链路控制信道(physical uplink control channel，PUCCH)。另外，SPS PDSCH对应的反馈信息可以称为SPS反馈信息，承载SPS PDSCH对应的反馈信息的资源也可以称为SPS反馈资源。
步骤2，网络设备向终端设备发送激活信息，终端设备接收来自网络设备的激活信息。
其中，该激活信息可以用于指示：SPS PDSCH所在的时域位置、SPS PDSCH的反馈信息所在的时域位置。另外，该激活信息可以承载于物理下行控制信道(physical downlink control channel，PDCCH)。
具体地，上述的激活信息可以通过DCI实现，实现方式如下：
[根据细则91更正 27.01.2021]　
通过DCI指示时域资源表中的索引(index)值，从而指示SPS PDSCH所在的时域位置。例如，请参照表1，表1为索引值、K0以及(S，L)的对应关系表，即时域资源表。其中，K0表示承载DCI的PDCCH与SPS PDSCH之间间隔的时隙个数，(S，L)表示SPS PDSCH位于时隙的符号S至符号S+L。假设DCI指示时域资源表中的索引值的值为1(即，K0＝1，S＝1，L＝2)，且承载该DCI的PDCCH位于时隙n，那么索引值为1的SPS PDSCH位于时隙n+1的符号1至符号2。
表1
索引 K0 (S，L)
0 1 (2，4)
1 1 (1，2)
2 2 (3，4)
3 2 (0，7)
[根据细则91更正 27.01.2021]　
另外，上述的时域资源表可以是协议预定义的，或者是通过高层信令或物理层信令配置的。
具体地，可以通过DCI指示SPS PDSCH的反馈信息所在的时域位置。例如，通过DCI承载指示信息，该指示信息用于指示K1集合中的一个K1的值，K1的值表示SPS PDSCH与SPS PDSCH的反馈信息之间间隔的时隙个数。其中，K1集合可以是通过高层信令配置的集合。如图1所示，假设第1个SPS PDSCH在时隙2，且K1＝2，那么该SPS PDSCH的反馈信息位于时隙4。
步骤3，网络设备基于SPS PDSCH的传输周期和激活信息，向终端设备周期性地发送SPS PDSCH。终端设备基于SPS PDSCH的传输周期和激活信息，周期性地接收来自网络设备的SPS PDSCH。
步骤4，终端设备确定每个SPS PDSCH对应的反馈信息，以及基于SPS PDSCH的传输周期和激活信息，周期性地向网络设备发送反馈信息。网络设备基于SPS PDSCH的传输周期，周期性地接收来自终端设备的反馈信息。
其中，终端设备确定SPS PDSCH对应的反馈信息，可以包括：首先，确定反馈时间单元；然后，根据SPS PDSCH对应的反馈信息生成HARQ-ACK码本；最后，确定承载HARQ-ACK码本的PUCCH资源。如图1所示，假设SPS PDSCH在时隙2，且K1＝2，则首先可以确定反馈时间单元为时隙4，然后根据该SPS PDSCH对应的反馈信息生成HARQ-ACK码本，最后根据HARQ-ACK码本的大小在时隙4的PUCCH集合中确定承载该HARQ-ACK码本的PUCCH资源。当然，终端设备确定SPS PDSCH对应的反馈信息的具体实施方式可以参考现有技术规定，在此不再赘述。
下面结合图1说明上述步骤3、步骤4。
如图1所示，假设SPS PDSCH的传输周期为1个时隙，DCI指示index＝1，K1＝2，且承载DCI的PDCCH位于时隙1，那么，网络设备分别在时隙2的符号1、符号2，时隙3的符号1、符号2，…，时隙n的符号1、符号2，周期性地向终端设备发送SPS PDSCH。对应地，终端设备分别在时隙2的符号1、符号2，时隙3的符号1、符号2，…，时隙n的符号1、符号2，周期性地接收来自网络设备的SPS PDSCH。然后，终端设备分别在时隙3、时隙4、…、时隙n，周期性地向网络设备发送反馈信息。对 应地，网络设备分别在时隙3、时隙4、…、时隙n，周期性地接收来自终端设备的反馈信息。其中，n为正整数。
另外，第1个SPS PDSCH可以被称为有调度信息的SPS PDSCH，第1个SPS PDSCH之后的SPS PDSCH均可以被称为无调度信息的SPS PDSCH。
基于上述步骤1-步骤4，网络设备与终端设备之间通过SPS PDSCH传输数据的过程中，在配置信息和激活信息被确定后，终端设备可以周期性地接收多个SPS PDSCH，并且可以周期性地向网络设备发送多个SPS PDSCH对应的反馈信息。
上述步骤1-步骤4仅为示例性说明。网络设备与终端设备之间通过半静态调度物理下行共享信道传输数据的具体实施方式，可以参照相应的现有技术规定。
3，资源的复用
若一个时间单元中存在两个数据业务对应的反馈信息，或者承载这两个数据业务对应的反馈信息的时域资源有重叠，终端设备可以将这两个数据业务对应的反馈信息复用后发送。如图2所示，假设PDSCH1对应的HARQ-ACK码本在PUCCH1上发送，PDSCH2对应的HARQ-ACK码本在PUCCH2上发送，且PUCCH1和PUCCH2位于同一个时隙，那么可以将这两个码本重组为一个新码本，并在该时隙确定一个新的PUCCH承载该新码本。例如，确定PUCCH3承载PDSCH1的HARQ-ACK码本和PDSCH2的HARQ-ACK码本。其中，PUCCH3的时域位置与PUCCH1的时域位置、PUCCH2的时域位置可能重叠，也可能不重叠。
在实现本申请实施例的过程中，本申请发明人发现：
网络设备与终端设备之间通过SPS PDSCH传输数据时，有调度信息的SPS PDSCH对应的反馈信息以及无调度信息的SPS PDSCH对应的反馈信息，均由K1指示，也即是说，每个无调度信息的SPS PDSCH对应的反馈信息所在的时域位置是固定的。当出现以下几种情况时，无调度信息的SPS PDSCH对应的反馈信息不被发送：
情况1，承载SPS PDSCH对应的反馈信息的资源位于半静态下行符号。
情况2，承载SPS PDSCH对应的反馈信息的资源位于动态下行符号。
情况3，承载SPS PDSCH对应的反馈信息的资源位于未指示用于上行传输的灵活符号。
换句话说，若承载无调度信息的SPS PDSCH对应的反馈信息的资源位于：下行符号，和/或，未指示用于上行传输的灵活符号，则不被发送。当无调度信息的SPS PDSCH对应的反馈信息不被发送时，网络设备不知道SPS PDSCH是否接收成功。因此，若网络设备重传SPS PDSCH，则会浪费资源，传输效率低下，若网络设备不重传SPS PDSCH，则又会导致数据丢失，数据传输可靠性低下。
另外，在实际应用中，上述情况1-情况3会频繁出现，即无调度信息的SPS PDSCH对应的反馈信息会频繁地不被发送，这会导致网络设备频繁地重传数据，从而导致丢包率高，数据传输可靠性低，传输时延大。
为了解决上述技术问题，本申请实施例提供一种通信方法及装置，以提高数据传输可靠性，降低传输时延，提升通信系统性能。需要说明的是，上述种种缺陷，均是发明人经过仔细实践研究后得出的结果。因此，上述问题的发现过程以及下文中本申请实施例针对上述问题所提出的解决方案，都应视为发明人在实现本申请过程中做出 的贡献。

需要说明的是，本申请实施例提供的通信方法，可以适用于图3所示的终端设备与网络设备之间，具体实现可以参考下述方法实施例，此处不再赘述。
应当指出的是，本申请实施例中的方案还可以应用于其他通信系统中，相应的名称也可以用其他通信系统中的对应功能的名称进行替代。
图3仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备，和/或，其他终端设备，图3中未予以画出。
下面将结合图4-图8对本申请实施例提供的通信方法进行具体阐述。
示例性地，图4为本申请实施例提供的通信方法的流程示意图一。该通信方法可以适用于图3所示的终端设备和网络设备之间的通信。
如图4所示，该通信方法可以包括如下步骤：
S401，终端设备确定第一上行资源。
其中，第一上行资源可以位于第一时间单元，且可以承载第一反馈信息，第一反馈信息可以为SPS PDSCH对应的反馈信息。
可选地，第一反馈信息可以包括：一个或多个SPS PDSCH对应的反馈信息。当第一反馈信息包括多个SPS PDSCH对应的反馈信息时，这里的多个SPS PDSCH的配置信息可以相同也可以不同。另外，上述的第一时间单元可以为时隙。
下面以第一反馈信息包括一个SPS PDSCH对应的反馈信息为例，并结合图5说明上述的S401。
请参照图5，假定SPS PDSCH位于时隙1，该SPS PDSCH对应的反馈信息承载于时隙3中的PUCCH1(图5中以虚线框示出)，终端设备可以确定：PUCCH1为第一上行资源，时隙3为第一时间单元。其中，关于SPS PDSCH、SPS PDSCH对应的反馈信息的说明可以参照上述步骤1-步骤4，在此不再赘述。
S402，若第一上行资源所占用的时域符号包括：下行符号，和/或，未指示用于上行传输的灵活符号，则终端设备确定第二时间单元和第二上行资源。
其中，第二上行资源位于第二时间单元内，第二上行资源所占用的时域符号均为用于上行传输的符号，且第二上行资源的时域起始位置可以位于第一上行资源的时域起始位置之后。
上述的第二上行资源可以包括：PUCCH、或上行共享物理信道(physical uplink shared channel，PUSCH)等。第二时间单元可以为时隙。一个资源的时域起始位置可以为：该资源所占用的所有时域符号中的第一个符号。另外，上述的下行符号以及未指示用于上行传输的灵活符号可以参照上述技术术语1中的说明，在此不再赘述。
下面结合图5说明上述S402。
请继续参照图5，PUCCH1(第一上行资源)所占用的时域符号为时隙3的符号1-符号3，且这3个符号均是下行符号，也即是说第一上行资源所占用的时域符号均为下行符号。为了成功发送PUCCH1，终端设备可以在时隙3的符号1之后的资源中，确定第二时间单元和第二上行资源。例如，可以将时隙3确定为第二时间单元，并将PUCCH2确定为第二上行资源。或者，也可以将时隙4确定为第二时间单元，并将PUCCH3确定为第二上行资源。其中，PUCCH2所占用的时域符号为时隙3的符号11-符号13，且这3个符号均是上行符号，PUCCH3所占用的时域符号为时隙4的符号1-符号3，且这3个符号均是上行符号。
一些可能的实施例中，第二时间单元可以位于第一时间单元之后，或者，第二时间单元和第一时间单元可以为同一时间单元。例如，若时隙4被确定为第二时间单元，PUCCH3被确定为第二上行资源，则第二时间单元位于第一时间单元之后。另一些可能的实施例中，若时隙3被确定为第二时间单元，PUCCH2被确定为第二上行资源，则第二时间单元和第一时间单元为同一时间单元。
如此，终端设备既可以在第一时间单元发送第一反馈信息，也可以在第一时间单元之后的时间单元发送第一反馈信息，可以提高终端设备发送第一反馈信息的灵活性。
可选地，为了减少终端设备的计算量，节省功耗，第二上行资源在第二时间单元中的相对位置与第一上行资源在第一时间单元中的相对位置可以相同(称为方式1)。其中，相对位置可以为：资源占用的首个符号在一个时隙中的符号编号，即该首个符号与该时隙的符号0之间间隔的符号个数。例如，假设一个时隙包括14个符号，按时间先后顺序分别为：符号0、符号1、…、符号13，该时隙中的一个PUCCH位于符号1-符号3，那么该PUCCH在该时隙中的相对位置为1。
请继续参照图5，由于PUCCH1的时域起始位置为时隙3的符号1，终端设备在确定第二时间单元和第二上行资源时，可以按时间先后顺序，在时隙3之后的多个时隙中，以符号1作为起始符号确定第二上行资源，例如，可以将时隙4确定为第二时间单元，并将PUCCH3确定为第二上行资源。
这样，存在第二上行资源的时域范围，可以从第一上行资源的时域起始位置之后的所有时域，缩小到第一上行资源的时域起始位置之后的每个时间单元中的部分符号，也即是说，终端设备可以在较小的时域范围内确定第二时间单元和第二上行资源，从而能够减少终端设备的计算量，节省功耗。
另一些可能的实施例中，为了减少终端设备的计算量，节省功耗，第二上行资源的时域宽度与第一上行资源的时域宽度可以相等，和/或，第二上行资源的频域宽度与第一上行资源的频域宽度可以相等(称为方式2)。
请继续参照图5，由于PUCCH1所占用的时域符号为时隙3的符号1-符号3，终端设备在确定第二时间单元和第二上行资源时，可以按时间先后顺序，在时隙3之后的多个时隙的符号1-符号3中，确定第二上行资源，例如，可以将PUCCH3确定为第二上行资源，并将时隙4确定为第二时间单元。
这样，存在第二上行资源的时域范围，可以从第一上行资源的时域起始位置之后的所有时域，缩小到第一上行资源的时域起始位置之后的部分时域，该部分时域为包括可用上行资源的时域，该可用上行资源的大小可以与第一上行资源的大小相等，也即是说，终端设备可以在较小的时域范围确定第二时间单元和第二上行资源，从而能够减少终端设备的计算量，节省功耗。
其中，上述的方式1、方式2可以独立实施，也可以结合实施，即第二上行资源在第二时间单元中的相对位置与第一上行资源在第一时间单元中的相对位置相同，且第二上行资源的时域宽度与第一上行资源的时域宽度相等，和/或，第二上行资源的频域宽度与第一上行资源的频域宽度相等。
这样，存在第二上行资源的时域范围，可以从第一上行资源的时域起始位置之后的所有时域，缩小至上述部分时域的每个时间单元中的部分符号，也即是说，终端设备可以在更小的时域范围确定第二时间单元和第二上行资源，从而能够减少终端设备的计算量，节省功耗。
一些可能的实施例中，上述的S402，可以包括如下几种实施方式：
方式3，可以包括如下几个步骤：
步骤5，确定第二时间单元。
其中，第二时间单元可以为一个或多个候选时间单元中时域位置最靠前的候选时间单元，每个候选时间单元的时域起始位置可以均不早于第一时间单元的时域起始位置，且每个候选时间单元可以均满足：第一条件，和/或，第二条件。
上述的第一条件可以为：存在可用SPS反馈资源，可用SPS反馈资源的时域符号均为用于上行传输的符号，且可用SPS反馈资源对应的码本比特区间的最大值可以大于或等于反馈比特数，该反馈比特数可以为：候选时间单元中的SPS反馈信息的码本比特数与第一反馈信息的码本比特数之和。换句话说，可用SPS反馈资源能够承载：候选时间单元中的SPS反馈信息以及第一反馈信息。
其中，候选时间单元中的SPS反馈信息可以为：该候选时间单元中的部分或全部SPS PDSCH对应的反馈信息。例如，请参照图6，若时隙4为候选时间单元，且时隙4中包括：SPS反馈信息1、SPS反馈信息2、SPS反馈信息3、SPS反馈信息4，那么可以选择这4个反馈信息中的部分或全部作为时隙4中的SPS反馈信息。
上述的第二条件可以为：存在上行信号，该上行信号可以包括上行数据或动态反馈信息。其中，承载上行数据的资源可以为PUSCH或PUCCH等。动态反馈信息可以为动态PDSCH对应的反馈信息。
另外，上述的SPS反馈信息以及可用SPS反馈资源可以参照上述技术术语2中 “SPS PDSCH”的说明，动态PDSCH对应的反馈信息的具体说明可以参考现有实现方式，在此不再赘述。
基于上述说明，候选时间单元也可以为：存在可用SPS反馈资源和/或上行信号，且时域起始位置不早于第一时间单元的时域起始位置的时间单元。另外，若第一时间单元中存在“可用SPS反馈资源和/或上行信号”，且该“可用SPS反馈资源和/或上行信号”的时域起始位置位于第一上行资源的时域起始位置之后，则第一时间单元也可以为候选时间单元。
可选地，上述可用SPS反馈资源对应的码本比特区间的最大值可以大于或等于反馈比特数，可以包括：候选时间单元中的可用SPS反馈资源对应的码本比特区间，可以包含候选时间单元中的SPS反馈信息与第一反馈信息的码本比特数之和，或者，候选时间单元中的可用SPS反馈资源对应的码本比特区间的最小值，可以大于候选时间单元中的SPS反馈信息与第一反馈信息的码本比特数之和。换句话说，可用SPS反馈资源不仅能够承载候选时间单元中的SPS反馈信息，还能够承载第一反馈信息，从而可以用一个反馈资源承载多个反馈信息，减少终端设备与网络设备的交互次数，降低信令开销，以提高通信效率。
步骤6，在第二时间单元中确定第二上行资源。
可选地，在第二时间单元中确定第二上行资源后，相当于将第一反馈信息延后至第二时间单元中的第二上行资源上发送，即第二时间单元中的SPS反馈信息可以包括第一反馈信息。换言之，终端设备确定的第二时间单元中，SPS反馈信息可以包括：其他SPS PDSCH对应的反馈信息以及第一反馈信息。例如，请参照图6，若确定时隙4为第二时间单元，那么，时隙4中的SPS反馈信息包括第一反馈信息以及其他SPS反馈信息。
下面结合图6说明上述的步骤5、步骤6。
请参照图6，时隙3为第一时间单元，PUCCH1为第一上行资源，时隙4中存在可用SPS反馈资源以及上行信号，时隙5中存在上行信号，时隙6中存在可用SPS反馈资源，从而时隙4、时隙5和时隙6均为候选时间单元。由于时隙4为这几个候选时间单元中时域位置最靠前的候选时间单元，因此可以确定时隙4为第二时间单元，然后终端设备可以在时隙4中确定第二上行资源。例如，终端设备可以将时隙4中承载上行信号的资源确定为第二上行资源，也即是说，通过时隙4中承载上行信号的资源来承载第一反馈信息。
这样，终端设备在第二时间单元中确定第二上行资源时，可以通过时间单元中已存在的可用SPS反馈资源承载第一反馈信息，或者通过时间单元中已存在的承载上行信号的资源承载第一反馈信息，也即是说，可以用一个反馈资源承载多个反馈信息，从而可以减少终端设备与网络设备的交互次数，降低信令开销，以提高通信效率。
可选地，步骤6，在第二时间单元中确定第二上行资源，可以包括：若第二时间单元满足第一条件且不满足第二条件，则确定第二时间单元中的可用SPS反馈资源为第二上行资源。或者，若第二时间单元满足第二条件，则确定第二时间单元中承载上行信号的资源为第二上行资源。
一种实施方式中，步骤6中的确定第二时间单元中的可用SPS反馈资源为第二上 行资源，可以包括：首先，确定第二时间单元中的SPS反馈信息。然后，根据该SPS反馈信息的有效载荷(payload)大小与第一反馈信息的有效载荷大小之和，在第二时间单元的半静态调度PUCCH资源集合中确定可用SPS反馈资源。最后，将该可用SPS反馈资源确定为第二上行资源。
其中，在第二时间单元的半静态调度PUCCH资源集合中确定可用SPS反馈资源，可以包括：在第二时间单元的半静态调度PUCCH资源集合中确定一个或多个第一可用PUCCH资源，其中，每个第一可用PUCCH资源均满足：占用的时域符号均为用于上行传输的符号，且对应的码本比特区间的最大值可以大于或等于上述的反馈比特数。将一个或多个第一可用PUCCH资源中，频域宽度和/或时域宽度最短，或者时域起始位置最早的第一可用PUCCH资源确定为可用SPS反馈资源。
一种实施方式中，步骤6中的确定第二时间单元中承载上行信号的资源为第二上行资源，可以包括：首先，确定第二时间单元中的动态反馈信息。然后，将动态反馈信息和第一反馈信息合并为一个反馈信息。之后，根据合并后的反馈信息的有效载荷大小，在第二时间单元的动态PUCCH资源集合中确定承载上行信号的资源。最后，将承载上行信号的资源确定为第二上行资源。
其中，在第二时间单元的动态PUCCH资源集合中确定承载上行信号的资源，可以包括：根据合并后的反馈信息的有效载荷大小以及DCI中的物理上行控制信道资源(PUCCH resource indicator，PRI)，在动态PUCCH资源集合中确定一个或多个第二可用PUCCH资源。其中，每个第二可用PUCCH资源均满足：占用的时域符号均为用于上行传输的符号，且对应的码本比特区间的最大值可以大于或等于上述的反馈比特数。将一个或多个第二可用PUCCH资源中，频域宽度和/或时域宽度最短，或者时域起始位置最早的第二可用PUCCH资源确定为承载上行信号的资源。
基于上述步骤6可知，终端设备可以优先通过时间单元中已存在的承载上行信号的资源承载第一反馈信息，由于承载上行信号的资源可以为动态反馈资源(如动态PDSCH)，且相较于可用SPS反馈资源，动态反馈资源所占用的信道条件可能更好，反馈成功率更高，因此优先通过承载上行信号的资源承载第一反馈信息，能够提高数据传输可靠性，降低传输时延，以提高通信效率。
可选地，上述步骤5之后，也可以不执行步骤6，而是执行下述步骤7，以在第二时间单元中确定第二上行资源：
步骤7，确定第二时间单元中的可用SPS反馈资源为第二上行资源，或者，确定第二时间单元中承载上行信号的资源为第二上行资源。
比较上述步骤6和步骤7的两种实施方式可知，两种实施方式的区别在于：步骤6可以优先通过时间单元中已存在的承载上行信号的资源承载第一反馈信息，而步骤7则是将第二时间单元中的可用SPS反馈资源或者承载上行信号的资源确定为第二上行资源。因此，步骤7的效果包括：将第二时间单元中的可用SPS反馈资源或者承载上行信号的资源确定为第二上行资源，可以用一个反馈资源承载多个反馈信息，从而可以减少终端设备与网络设备的交互次数，降低信令开销，以提高通信效率。
方式4，确定第二时间单元，以及在第二时间单元中确定第二上行资源。
其中，第二时间单元可以为一个或多个候选时间单元中时域位置最靠前的候选时 间单元，每个候选时间单元的时域起始位置可以均不早于第一时间单元的时域起始位置，且每个候选时间单元可以均满足候选条件。该候选条件可以包括如下任一项：存在上行符号、存在反馈信息、存在动态反馈信息或者存在SPS反馈信息。
比较上述方式3和方式4可知，方式4与方式3之间可以相互替换，因此，方式4的实施方式及效果可以参照方式3，在此不再赘述。
方式5，确定第三时间单元。其中，第三时间单元可以为：在第一上行资源的时域起始位置之后，且包含可用上行资源的时间单元，可用上行资源所占用的时域符号均为用于上行传输的符号。将第三时间单元确定为第二时间单元，并将第三时间单元中的可用上行资源确定为第二上行资源。
下面结合图5、图7、图8以及几个示例说明如何实现方式5。
示例1，首先，确定第二上行资源的大小和位置。其中，第二上行资源的大小等于第一上行资源的大小，第二上行资源在一个时间单元中的相对位置，与第一上行资源在第一时间单元中的相对位置相同。另外，一个资源的大小等于另一个资源的大小可以是：一个资源的时域宽度与另一个资源的时域宽度相等，和/或，一个资源的频域宽度与另一个资源的频域宽度相等。
然后，根据第二上行资源的大小和位置，确定第三时间单元。其中，第三时间单元可以为：在第一时间单元之后，且包含第三可用上行资源的首个时间单元，该第三可用上行资源的大小与第一上行资源的大小相等，第三可用上行资源在第三时间单元中的位置，与第一上行资源在第一时间单元中的位置相同，且第三可用上行资源所占用的时域符号均为用于上行传输的符号。
最后，将第三时间单元确定为第二时间单元，并将第三时间单元中的第三可用上行资源确定为第二上行资源。
请参照图5，时隙3为第一时间单元，PUCCH1为第一上行资源，且PUCCH1位于时隙3的符号1-符号3。终端设备可以按时间先后顺序，从时隙3开始，在时隙3之后的每个时隙的符号1-符号3中，将首个存在第三可用上行资源的时隙确定为第三时间单元，如图5中的时隙4。然后，将时隙4确定为第二时间单元，并将时隙4的符号1-符号3中的PUCCH3确定为第二上行资源。
示例2，首先，确定第二上行资源的大小。其中，第二上行资源的大小等于第一上行资源的大小。
然后，根据第二上行资源的大小，确定第三时间单元。其中，第三时间单元可以为：在第一时间单元之后，且包含第四可用上行资源的首个时间单元，该第四可用上行资源的大小与第一上行资源的大小相等。
最后，将第三时间单元确定为第二时间单元，并将第三时间单元中的第四可用上行资源确定为第二上行资源。
请参照图7，时隙3为第一时间单元，PUCCH1为第一上行资源，且PUCCH1位于时隙3的符号1-符号3。终端设备可以按时间先后顺序，从时隙3的符号3开始，在时隙3的符号3之后的每个符号中，将首个存在第四可用上行资源的时隙确定为第三时间单元，如图7中的时隙3。然后将时隙3确定为第二时间单元，并将时隙3的符号11-符号13中的PUCCH2确定为第二上行资源。
示例3，首先，根据第一上行资源的大小确定第五可用上行资源。其中，第五可用上行资源可以为：在时域上位于第一上行资源之后的上行资源，且第五可用上行资源的大小大于或等于第一上行资源的大小。
然后，将第五可用上行资源确定为第二上行资源，并将第五可用上行资源所在的时间单元确定为第二时间单元。
请参照图8，时隙3为第一时间单元，PUCCH1为第一上行资源。终端设备可以按时间先后顺序，从时隙3开始，在时隙3之后的每个时隙的PUCCH资源集合(包括PUCCH资源集合1、PUCCH资源集合2、PUCCH资源集合3)中，将首个存在第五可用上行资源的时隙确定为第三时间单元，如图8中的时隙4。然后将时隙4确定为第二时间单元，并将时隙4的PUCCH2确定为第二上行资源。
结合上述示例1-示例3可知，方式5提供了多种确定第二时间单元和第二上行资源的实施方式，可以将反馈信息延后至第二上行资源发送，避免反馈信息被取消发送，如此，网络设备可以根据该反馈信息确定SPS PDSCH是否接收成功，并确定是否重传数据，以减少数据丢失的概率，提高数据传输可靠性，且可以降低数据重传的次数，节省资源，提高传输效率，进而提高通信效率。
结合上述方式3-方式5可知，基于方式3-方式5所确定的第二时间单元可以位于第一时间单元之后，或者，第二时间单元和第一时间单元可以为同一时间单元。基于方式3-方式5所确定的第二上行资源在第二时间单元中的相对位置与第一上行资源在第一时间单元中的相对位置可以相同。基于方式3-方式5所确定的第二上行资源在第二时间单元中的相对位置与第一上行资源在第一时间单元中的相对位置可以相同。
另外，上述的用于上行传输的符号可以包括如下一项或多项：半静态配置的上行符号、动态指示的用于上行传输的灵活符号、或被配置为上行传输的灵活符号等。
一些可能的实施例中，S402之后，图4所示的通信方法还可以包括如下步骤：
步骤8，若满足合并发送条件，则确定第三上行资源。该第三上行资源可以承载第一反馈信息和第二反馈信息。
其中，合并发送条件可以为：第二时间单元包括第二反馈信息，或者第二上行资源与承载第二反馈信息的资源重叠。
上述的第二反馈信息可以为上行数据，例如，SPS PDSCH对应的反馈信息、动态PDSCH对应的反馈信息等。当第二时间单元中包括该第二反馈信息，或者第二上行资源与承载第二反馈信息的资源重叠时，终端设备可以通过复用的方式，确定第三上行资源以承载第一反馈信息和第二反馈信息。其中，这里的第三上行资源可以与第二上行资源相同，也可以与第二上行资源不同。
这样，不仅可以用一个反馈资源承载多个反馈信息，减少终端设备与网络设备的交互次数，降低信令开销，还能够通过资源复用的方式，避免资源冲突，减少第一反馈信息被取消发送的次数，从而可以提高数据传输可靠性，降低传输时延，以提高通信效率。
在执行步骤8，确定第三上行资源后，终端设备还可以在第三上行资源上发送第一反馈信息和第二反馈信息。
另外，终端设备通过复用的方式确定第二上行资源可以参照上述技术术语3，在 此不再赘述。
S403，终端设备在第二上行资源上发送第一反馈信息，网络设备在第二上行资源上接收第一反馈信息。
其中，S403中的网络设备在第二上行资源上接收第一反馈信息的实施方式，可以参照S401、S402，在此不再赘述。
网络设备在接收到第一反馈信息后，若第一反馈信息包括肯定应答信息，则确定终端设备成功接收到SPS PDSCH。若第一反馈信息包括否定应答信息，则确定终端设备接收失败，网络设备可以向终端设备重传SPS PDSCH。
基于图4所示出的通信方法，若第一上行资源被取消发送，例如第一上行资源所占用的时域符号包括：下行符号，和/或，未指示用于上行传输的灵活符号，则终端设备可以在第一上行资源的时域起始位置之后的资源中，确定第二时间单元和第二上行资源，以及并在第二上行资源上发送第一反馈信息。如此，SPS PDSCH对应的反馈信息在第一上行资源不被发送时，终端设备可以将反馈信息延后至第二上行资源发送。如此，网络设备可以根据该反馈信息确定SPS PDSCH是否接收成功，并确定是否重传数据，以减少数据丢失的概率，提高数据传输可靠性，且可以降低数据重传的次数，节省资源，提高传输效率，进而提高通信效率。
