图1是根据本申请实施例提供的通信方法的示意性流程图。
101，在网络侧设备一次调度的最小时间调度单元数目为S，该网络侧设备与终端设备采用第一传输模式进行数据传输时，该网络侧设备从N个调度规则中确定目标调度规则，其中，该调度规则包括该一次调度的传输块个数T和该一次调度的T个传输块和S个最小时间调度单元的映射关系中的至少一个，N为大于或等于2的正整数，T为大于或等于1的正整数，S为大于或等于1的正整数，该第一传输模式为单天线传输方案或多天线传输方案。
该多天线传输方案可以是发射分集传输方案、空间复用传输方案、多用户多入多出(multiple-input multiple-output，MIMO)传输方案，协作多点传输(coordinated multiple points transmission/reception，CoMP)或波束成型传输方案等，也可以是各种天线端口、层、流或秩配置。该第一传输模式是该网络侧设备确定的一种传输模式。该第一传输模式可以是LTE系统中定义的传输模式(transmission mode，TM)1到10中的任一种传输模式，也可以是其他(例如5G等)的传输模式，本申请的实施例对此不作限定。后文的实施例以单天线传输方案或非空分复用传输方案为例，多天线传输方案或空分复用传输方案可类似得到。
这里的传输块可以是LTE协议中所称的传输块(transport block，TB)，也可以是其他通信系统(例如5G等)中的具有同样功能的传输单元。
这里的最小时间调度单元可以是传输时间间隔(transmission time interval，TTI)、时隙(slot)、时域符号或由一个或多个时域符号组成的迷你时隙(mini slot)。其中，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接入(single carrier frequency division multiple access，SC-FDMA)符号。以下将时域符号简称为符号。
102，终端设备确定目标调度规则。
103，网络侧设备和终端设备根据该目标调度规则进行通信。这里的通信可以是上行通信也可以是下行通信。
通常一个传输块需要多个比特的控制信息，例如，新数据指示符(new data indicator，NDI)、冗余版本(redundancy version，RV)、混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息指示等。因此，传输块的数目越少，需要的控制信息的比特数就越少，对应的控制信息的开销就越小。此外，一个传输块映射到最小时间调度单元越多时，一个传输块的传输时间间隔(transmission time interval，TTI)越长，越有助于提升终端设备的上行覆盖范围。可选地，在一个传输块映射到多个最小时间调度单元的情况下，传输块大小(transport block size，TBS)可以更大。换句话说，TBS可以正比于最小时间调度单元的数据。更大的TBS可以获得更高的编码增益。在发送端和接收端的处理时延相同的情况下，TTI越长，保持连续传输所需要的HARQ进程数就越少。相同的时间内传输的传输块数目越少，媒体访问控制(medium access control，MAC)层和无线链路控制(radio link control，RLC)层头开销和循环冗余校验(cyclic redundancy check，CRC)开销就越小。相反，相同的时间内传输的传输块数目越多，每个传输块的TTI越短，单向延迟越小，在某些场景下(比如高速移动场景，突发干扰等场景)选择这种调度规则，能够提升数据传输效率。因此，根据图1所示的方法可以选择合适的调度规则来适应不同的场景。此外，每个最小时间调度单元在频域上还可以承载多个的传输块。根据图1所示的方法还可以满足传输块灵活资源复用的需求，例如重传使用更少的资源通常可以避免资源浪费提升频谱效率，或者重传使用更多的资源可以保证时延和可靠性。
在调度规则包括一次调度的传输块个数T的情况下，该N个调度规则中不同的调度规则包括的一次调度的传输块个数T是不同的。换句话说，根据不同的调度规则确定的一次调度的传输块个数和最小时间调度单元个数的比例关系可以是不同的。在调度规则包括一次调度的T个传输块和S个最小时间调度单元的映射关系的情况下，该N个调度规则中的不同的调度规则所指示一次调度的传输块个数和最小时间调度单元个数的比例关系也可以是不同的。综上所述，根据N个调度规则确定的传输块个数和最小时间调度单元个数的比例关系可以是以下任意两种：1:1，1:P，Q:P或Q:1，其中，P与Q均为正整数，且P不等于Q。
可选的，在一些实施例中，该调度规则还可以包括：一次调度的传输块数T、一次调度中的T个传输块和S个最小时间调度单元的映射关系，和一次调度中的一个传输块映射的最小时间调度单元数中的至少一个。
为了帮助本领域技术人员更好地理解本申请的技术方案，下面通过表1示出N个调度规则。表1所示实施例中，假设一次调度的最小时间调度单元数目为4。
调度规则序号 传输块数目 传输块与最小时间调度单元的映射关系
1 1 T 1～(S 1,S 2,S 3,S 4)
2 2 T 1～(S 1,S 2),T 2～(S 3,S 4)
3 4 T 1～(S 1),T 2～(S 2),T 3～(S 3),T 4～(S 4)
表1
如表1所示的调度规则中包括一次调度的传输块数目和一次调度T个传输块与S个最小时间调度单元的映射关系，其中，T t～(S s)表示T个传输块中的第t个传输块映射到S个 最小时间调度单元中的第s个最小时间调度单元。例如，上述调度规则3中，T 1～(S 1)表示4个传输块中的第一个传输块映射到4个最小时间调度单元中的第一个最小时间调度单元。再如，上述调度规则2中，T 2～(S 3,S 4)表示2个传输块中的第二个传输块映射到4个最小时间调度单元中的第三个最小时间调度单元和第四个最小时间调度单元。如表1所示的调度规则还可以有其他的表现形式，例如可以只包括一次调度中的传输块数目或只包括一次调度中T个传输块与S个最小时间调度单元的映射关系。

表2
表3是另一个调度规则的示意。
Figure PCTCN2017118918-appb-000002
表3
如表2和表3所示的调度规则包括一次调度的T个传输块的每一个传输块映射最小时间调度单元的数。根据以上规则和一次调度的最小时间调度单元数S可以确定当前一次调度的传输块个数T和一次调度的T个传输块与S个最小时间调度单元的映射关系。比如假设采用调度规则为2，且一次调度的最小时间调度单元数S为4，则可知道当前一次调度的传输块个数T为2，且2个TB分别映射到第1、第2个和第3、第4个最小时间调度单元上。
可以理解的是，上述调度规则仅是为了帮助本领域技术人员更好地理解调度规则的意义，而并非对调度规则的限制，比如调度规则可以是以上表格中规则的子集或者扩展或者修改，例如实际系统中可以只存在表1中的2种调度规则，1种为S个最小调度时间单元上1个传输块(调度规则1)，另一种为S个最小调度时间单元上S个传输块(调度规则3)。
可选的，在一些实施例中，网络侧设备可以确定与该终端设备进行通信时使用的参数 信息，然后根据参数信息与调度规则的对应关系，确定该N个调度规则中与确定的参数信息对应的调度规则为该目标调度规则。该参数信息可以是该网络侧设备与该通信设备通信时使用的子载波间隔。该参数信息也可以是该网络侧设备与该通信设备通信时使用的最小时间调度单元占用的符号数目。该参数信息也可以是该网络侧设备与该终端设备通信时使用的子载波间隔和最小时间调度单元占用的符号个数。
表4是一个参数信息与调度规则的对应关系的示意。表4中的参数信息为子载波间隔。
子载波间隔 调度规则序号
15kHz 3
30kHz 2
60kHz 1
表4
表4中所示的调度规则序号表示的调度规则与表1中所示的相同序号表示的调度规则相同。例如，表4中调度规则序号为3的调度规则为表1中调度规则序号为3的调度规则，即传输块的数目为4，且T 1～(S 1),T 2～(S 2),T 3～(S 3),T 4～(S 4)。
表5是另一参数信息与调度规则的对应关系。表5中的参数信息为子载波间隔，调度规则为一个传输块映射最小时间调度单元的数目。

表5
为了避免冗余，表5以一张表的形式表示了多个实施例。例如，在一个实施例中，在子载波间隔为30kHz的情况下，一个传输块映射最小时间调度单元的数目为1，且在子载波间隔为60kHz的情况下，一个传输块映射最小时间调度单元数目为2。在另一些实施例中，在子载波间隔为30kHz的情况下，一个传输块映射最小时间调度单元的数目为2，且在子载波间隔为60kHz的情况下，一个传输块映射最小时间调度单元数目为4，以此类推。
表6是另一个参数信息与调度规则的对应关系的示意。表6中的阐述信息为一个最小时间调度单元的符号数目。

表6
与表4类似，表6中所示的调度规则序号表示的调度规则与表1中所示的相同序号表示的调度规则相同。
表7是另一个参数信息与调度规则的对应关系的示意。表7中的传输信息为子载波间隔和一个最小时间调度单元的符号数目。
Figure PCTCN2017118918-appb-000005
表7
与表4和表6类似，表7中所示的调度规则序号表示的调度规则与表1中所示的相同序号表示的调度规则相同。
表8是另一个参数信息与调度规则的对应关系的示意。表8中的传输信息为子载波间隔和一个最小时间调度单元的符号数目。
Figure PCTCN2017118918-appb-000006
表8
与表5类似，为了避免冗余，表8以一张表的形式表示了多个实施例。
可以理解的是，上述调度规则仅是为了帮助本领域技术人员更好地理解调度规则的意义，而并非对调度规则的限制，比如调度规则可以是以上表格中规则的子集或者扩展或者修改。又比如5G/NR里子载波间隔还可以是3.75kHz，7.5kHz，120kHz，240kHz，480kHz，960kHz，最小时间调度单元符号数目也可以是1，2，3，4等，又比如一次调度的最小时间单元数并非限定在表1中的S＝4，可以是任意一个正整数值，比如S＝1，2，3，5，6，7或者8等等。对于这些配置可以定义或规定类似的调度的规则，本文不再赘述。
进一步，在一些实施例中，该终端设备可能只支持一种子载波间隔和最小时间调度单元符号数目。在此情况下，该终端设备可以确定该目标调度规则为该终端支持的子载波间隔和/或最小时间调度单元符号数目对应的调度规则。
可选的，在一些实施例中，一个最小时间调度单元时长越短，一个传输块映射的最小时间调度单元越多。例如，在子载波间隔为15KHz且一个最小时间调度单元占用的OFDM符号数目为14的情况下，一个最小时间调度单元时长为1ms，一个传输块映射的最小时间调度单元的个数为1。一个传输块映射到最小时间调度单元越少时，一个传输块的TTI越短。每个传输块的TTI越短，单向延迟越小。这样，可以避免过长的TTI导致的时延问题，比如满足5G eMBB 4ms的单向时延要求。再如，在子载波间隔为60kHz且一个最小时间调度单元占用的OFDM符号数目为7的情况下，一个最小时间调度单元时长为0.125ms，一个传输块映射的最小时间调度单元的个数可以为4。将一个传输块映射到最小时间调度单元越多时，一个传输块的TTI越长。这样有助于提升该传输块的覆盖距离。一 个传输块映射到多个最小时间调度单元时，可以传输更大的传输块，更大的TBS可以获得更高的编码增益。在发送端和接收端的处理时延相同的情况下，TTI越长，相同处理时延和传输时延前提下，保持连续传输所需要的HARQ进程数就越少。此外，相同时间内调度的传输块越少，可以降低MAC层和RLC层头开销和CRC开销，还可以降低控制开销(比如下行控制和HARQ反馈开销)。
可选的，在另一些实施例中，网络侧设备还可以确定无线资源信息。网络侧设备根据无线资源信息和调度规则的对应关系，确定该N个调度规则中与确定的无线资源信息对应的调度规则为该目标调度规则。该无线资源信息可以是该网络侧设备当前可用的资源块(resource block，RB)数量或者在使用多入多出(multiple-input multiple-output，MIMO)通信时码字分配的层数。例如对于5G/4.5G，考虑到可能使用更小的调度单元(比如最小时间调度单元符号数可能为1或者2)，为了传输更大的TB，则需要1TB映射到多个最小时间调度单元。又比如对于小区边缘用户，受限功率谱密度，分配的资源块少，可以通过1个传输块映射到多个最小时间调度单元实现覆盖提升、传输更大的传输块。
假设此时该N个调度规则如表1所示的3个调度规则。若该当前可用的RB数量小于第一预设RB数量阈值，则该目标调度规则可以是调度规则序号为1的调度规则，即一个传输块映射到四个最小时间调度单元。在RB数较少时将一个传输块映射到多个最小时间调度单元可以使得TBS大，大TBS可以获得更高的编码增益，降低MAC层和RLC层头开销和CRC开销。进一步，在一些实施例中，若该当前可用的RB数量大于第一预设RB数量阈值，则该目标调度规则可以是调度规则序号为3的调度规则，即一个传输块映射到一个最小时间调度单元。
可选的，在另一些实施例中，网络侧设备还可以确定该终端设备的工作状态。网络侧设备根据终端设备的工作状态和调度规则的对应关系，确定该N个调度规则中与确定的该终端设备的工作状态对应的调度规则为该目标调度规则。该终端设备的工作状态可以包括该终端设备的位置信息，例如该终端设备位于小区边缘或小区中心，是否覆盖受限。该终端设备的工作状态还可以包括该终端设备的移动速度，例如该终端设备处于高速移动状态、低速移动状态等。该终端设备的工作状态可以是该终端设备上报给该网络侧设备的，也可以是该网络侧设备测量得到的。
假设此时该N个调度规则如表1所示的3个调度规则。若该终端设备处于低速移动状态或位于小区边缘位置或覆盖受限场景，则该目标调度规则可以是调度规则序号为1的调度规则，即一个传输块映射到四个最小时间调度单元。这样，可以提升终端设备的覆盖范围。进一步，在一些实施例中，该终端设备处于高速移动状态或位于小区中心或非覆盖受限场景，则该目标调度规则可以是调度规则序号为3的调度规则，即一个传输块映射到一个最小时间调度单元。
可选的，在另一些实施例中，网络侧设备还可以确定无线环境信息。网络侧设备根据无线环境信息和调度规则的对应关系，确定该N个调度规则中与确定的无线环境信息对应的调度规则为该目标调度规则。该无线环境信息可以是与信道相关的测量信息，也可以是当前网络配置或调度相关的信息。例如是否发生邻小区突发干扰，是否发生超高可靠低时延通信(ultrao-reliable low latency communication，URLLC)影响(比如资源抢占，打孔等)等，例如一种常用的做法是将系统带宽划分为两部分：仅增强移动宽带通信(enhanced  mobile broadband，eMBB)业务区域，该区域不会出现URLLC业务的影响；eMBB和URLLC共存区，该区域eMBB业务可能受到URLLC业务的影响。对于eMBB和URLLC共存区可以如表1所示的调度规则序号为3的调度规则或一个传输块映射到一个最小时间调度单元，从而能更好的对抗URLLC影响。
假设此时该N个调度规则如表1所示的3个调度规则。在发生邻小区突发干扰或URLLC影响的情况下，该目标调度规则可以是调度规则序号为3的调度规则，即一个传输块映射到一个最小时间调度单元。在未发生邻小区突发干扰或URLLC影响的情况下，该目标调度规则可以是调度规则序号为1的调度规则，即一个传输块映射到四个最小时间调度单元。在发生邻小区突发干扰或URLLC影响的情况下，邻小区突发干扰或URLLC干扰可能仅影响一个最小时间调度单元上的数据。在一个传输块映射到多个最小时间调度单元的情况下，该多个最小时间调度单元仅有一个对应的反馈信息。因此，可能造成所述调度的所有最小时间单元上的数据需要重传。而若一个传输块映射到一个最小时间调度单元，则每个最小时间调度单元都有控制信息和反馈信息。这样，仅受影响的最小时间单元上的数据需要重传，存在频谱效率性能增益，可以获得更好的链路性能。此外，如果每个传输块仅调度到一个最小调度时间单元上，则可通过调度方式避免eMBB和URLLC的碰撞冲突。
除了根据是否发生邻小区干扰或URLLC干扰来确定该目标调度规则外，该网络侧设备还可以根据其他可以反映信道质量的参数或场景来选择合适的目标调度规则。信道变化越快或者不同符号或子带上信道之间偏差越大，一个传输块映射的最小时间调度单元数目越少，信道变化越小或者不同符号或子带上信道之间偏差越小，一个传输块映射的最小时间调度单元数目越多。
当然，在另一些实施例中，网络侧设备还可以根据上述信息中的两个或两个以上信息，从该N个调度规则中确定该目标调度规则。例如，在满足时延需求和未发生干扰的情况下，即使在小区中心用户或非覆盖受限场景中，一个传输块也可以映射到多个最小调度单元。
可选的，在一些实施例中，在步骤102之前，该网络侧设备还可以向该终端设备发送目标调度规则指示信息，该目标调度规则指示信息用于指示该网络侧设备确定的该目标调度规则。该终端设备确定目标调度规则，包括：该终端设备根据接收到的目标调度规则指示信息，确定该目标调度规则。
可以理解的是，该网络侧设备所确定的目标调度规则为该终端设备支持的目标调度规则。
可选的，在一些实施例中，在步骤101之前，该终端设备可以向该网络侧设备发送调度规则信息，所述调度规则信息用于指示该网络侧设备该终端设备支持的调度规则。
可选的，该网络侧设备可以通过隐式或显示的方式将该目标调度规则指示信息发送至该终端设备。
可选的，在一些实施例中，该目标调度规则指示信息包括以下中的至少一种：子载波间隔、最小时间调度单元占用的符号数目、下行控制信息(downlink control information，DCI)格式、调制预编码方案(modulation and coding scheme，MCS)、循环冗余校验码，和分配的资源块数。
例如，该终端设备可以保存或预定义或生成如表4所示的子载波间隔和调度规则的对 应关系。若该网络侧设备当前配置或使用15kHz的子载波间隔，则确定的目标调度规则为序号为3的调度规则，该网络侧设备可以显示或隐式地指示该终端设备使用15kHz的子载波间隔，显示通知包括控制信令通知(比如广播信道，高层信令，物理层信令等)；隐式通知包括，用户盲检测广播信道或同步信道等确定子载波间隔。在此情况下，该终端设备可以根据子载波间隔和调度规则的对应关系，确定调度规则序号为3的调度规则为该目标调度规则。
再如，该终端设备可以保存或预定义或生成如表6所示的最小时间调度单元占用的符号数目与调度规则的对应关系。若该网络侧设备当前配置或使用最小时间调度单元占用的符号数目为14，则确定的目标调度规则为序号为3的调度规则，该网络侧设备可以指示该终端设备使用最小时间调度单元占用的符号数目为14。在此情况下，该终端设备可以根据最小时间调度单元占用的符号数目和调度规则的对应关系，确定调度规则序号为3的调度规则为该目标调度规则。
又如，该终端设备可以保存或预定义或生成如表7所示的对应关系。若该网络侧设备当前配置或使用子载波间隔为15kHz且最小时间调度单元占用的符号数目为14，则确定的目标调度规则为序号为3的调度规则，该网络侧设备可以指示该终端设备使用子载波间隔为15kHz且最小时间调度单元占用的符号数目为14。在此情况下，该终端设备可以根据最小时间调度单元占用的符号数目和调度规则的对应关系，确定调度规则序号为3的调度规则为该目标调度规则。
又如，该网络侧设备和该终端设备可以保存或预定义或生成如表9所示的DCI格式与调度规则的对应关系。
DCI格式 调度规则序号
A 3
B 2
C 1
表9
表9所示的A、B、C表示不同的DCI格式。若该网络侧设备确定的目标调度规则为序号为3的调度规则，则该网络侧设备可以使用DCI格式为A。在此情况下，该终端设备可以根据检测到的DCI格式与调度规则的对应关系，确定调度规则序号为3的调度规则为该目标调度规则。
又如，该网络侧设备和该终端设备可以保存或预定义或生成如表10所示的MCS与调度规则的对应关系。

表10
表10中MCS 1～MCS 6表示不同的MCS索引。若该网络侧设备配置或使用MCS 1～MCS 2之间的MCS，则确定的目标调度规则为序号为3的调度规则，则该网络侧设备可以指示该终端设备使用的MCS为MCS 1～MCS 2的值。在此情况下，该终端设备可以根据 MCS与调度规则的对应关系，确定调度规则序号为3的调度规则为该目标调度规则。
又如，该网络侧设备和该终端设备可以保存或预定义或生成如表11所示的CRC与调度规则的对应关系。

CRC 3 1
表11
表11中CRC 1、CRC 2和CRC 3表示三种不同的CRC。若该网络侧设备确定的目标调度规则为序号为3的调度规则，则该网络侧设备可以为DCI加上CRC 1的CRC。在此情况下，该终端设备在确定出CRC后，可以根据CRC与调度规则的对应关系，确定使用调度规则序号为3的调度规则为该目标调度规则。
又如，该网络侧设备和该终端设备可以保存或预定义或生成如表12所示的RB数与调度规则的对应关系。

表12
如表12所示，若该网络侧设备配置或使用RB数目小于或等于RB 1，则确定的目标调度规则为序号为3的调度规则，该网络侧设备可以指示该终端设备使用的RB数目小于或等于RB 1。在此情况下，该终端设备可以根据RB数与调度规则的对应关系，确定调度规则序号为3的调度规则为该目标调度规则。
可以理解的是，上述所有表格和对应关系仅是为了帮助本领域技术人员更好地理解，而并非对对应关系的限制，比如对应关系可以是以上表格中对应关系的子集或者扩展或者修改。例如以上实施例都是以表1的调度规则举例，若采用表2或表3的调度规则类似，在此不再赘述。
可选的，在一些实施例中，该目标调度规则信息可以与DCI所在的搜索空间位置相对应。可以理解的是，由于DCI所在的搜索空间仅为公共搜索空间和用户搜索空间，因此仅能够通过DCI所在的搜索空间指示两种调度规则。例如，若网络侧设备确定该目标调度规则为序号为3的调度规则，则可以将DCI承载在公共搜索空间，若网络侧设备确定该目标调度规则为序号为1的调度规则，则可以将DCI承载在用户搜索空间。该终端设备可以根据检测出的DCI所在的位置，确定该目标调度规则。
可以理解的是，在一些实施例中，考虑到利用DCI所在的搜索空间仅能够指示两种调度规则，可选的可以利用其它方式指示剩余的调度规则。例如，利用CRC、RB数等。
可选的，在一些实施例中，该目标调度规则信息可以与DCI所在的资源位置相对应。可以理解的是，终端设备可以根据检测出的DCI所在的资源位置(比如RB编号，或者子带编号，或者CCE编号)，确定该目标调度规则。
可选的，在另一些实施例中，该网络侧设备可以采用显示的方式将该目标调度规则指 示信息发送至该终端设备。具体地，该网络侧设备可以利用控制信令上的一些字段将该目标调度规则指示信息发送至该终端设备。该控制信令可以是MAC层控制信令、也可以是物理层控制信令。
可选的，在一些实施例中，用于指示目标调度规则的字段(以下简称：目标调度规则指示字段)可以是控制信令上的新增的字段。以DCI为例，可以在DCI上增加目标调度规则指示字段。该网络侧设备在确定了该目标调度规则之后，可以将该目标调度规则指示字段的值设置为与该目标调度规则对应的值。该终端设备在接收到该DCI后，可以根据该DCI中的目标调度规则指示字段的值确定出该目标调度规则。除此之外，也可以采用MAC层或无线资源控制(radio resource control，RRC)层等高层信令指示目标调度规则。
可选的，在一些实施例中，调度规则可以仅包括一次调度的传输块个数T。同时，一次调度的传输块个数T能整除S。在此情况下，一次调度的T个传输块和S最小时间调度单元的映射关系为：该T个传输块中的每个传输块映射到S个最小时间调度单元中的一个最小时间调度单元；或者，T个传输块中的每个传输块映射到该S个最小时间调度单元；或者，该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，其中，S＝S t*T，S t为大于1且小于S的正整数。更进一步，该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，包括：该T个传输块中的第t个传输块映射到该S个最小时间调度单元中的第(t-1)*S t+1个最小时间调度单元至第t*S t个最小时间调度单元，其中t＝1,…,T，S t＝S/T，*表示乘号。
例如，假设一次调度中的最小时间调度单元数目为4。若该目标调度规则包括一次调度中的传输块数目为2，则该2个传输块中的第一个传输块映射到第一个最小时间调度单元和第二个最小时间调度单元，该2个传输块中的第二个传输块映射到第三个最小时间调度单元和第四个最小时间调度单元。若该终端设备确定的目标调度规则包括一次调度中的传输块数目为4，则该终端设备可以确定4个传输块分别映射到4个最小时间调度单元。
该网络侧设备可以保存或预定义或生成该一次调度中的T个传输块和S最小时间调度单元的映射关系。这样，该网络侧设备可以根据目标调度规则中包括的一次调度中的传输块个数和该网络侧设备保存或预定义或生成的该一次调度中的T个传输块和S最小时间调度单元的映射关系，确定出每个传输块映射的最小时间调度单元。
类似的，该终端设备也可以保存或预定义或生成该一次调度中的T个传输块和S最小时间调度单元的映射关系。该终端设备可以根据目标调度规则中包括的一次调度中的传输块个数和该终端设备保存或预定义或生成的该一次调度中的T个传输块和S最小时间调度单元的映射关系，确定出每个传输块映射的最小时间调度单元。
可选的，在另一些实施例中，该N个调度规则中的每个调度规则可以仅包括一次调度的一个传输块映射的最小时间调度单元数。同时，该每个调度规则包括的一次调度的一个传输块映射的最小时间调度单元数能被S整除。在此情况下，一次调度的T个传输块和S最小时间调度单元的映射关系为：该T个传输块中的每个传输块映射到S个最小时间调度单元中的一个最小时间调度单元；或者，T个传输块中的每个传输块映射到该S个最小时间调度单元；或者，该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，其中，S＝S t*T，S t为大于1且小于S的正整数。更进一步，该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单 元，包括：该T个传输块中的第t个传输块映射到该S个最小时间调度单元中的第(t-1)*S t+1个最小时间调度单元至第t*S t个最小时间调度单元，其中t＝1,…,T，S t＝S/T。

该网络侧设备可以保存或预定义或生成该一次调度的T个传输块和S最小时间调度单元的映射关系。这样，该网络侧设备可以根据目标调度规则中包括的一次调度中的一个传输块映射的最小时间调度单元数和该网络侧设备保存或预定义或生成的该一次调度中的T个传输块和S最小时间调度单元的映射关系，确定出一次调度中的传输块数以及每个传输块映射的最小时间调度单元。
类似的，该终端设备也可以保存或预定义或生成该一次调度的T个传输块和S最小时间调度单元的映射关系。该终端设备可以根据目标调度规则中包括的一次调度的一个传输块映射的最小时间调度单元数和该终端设备保存或预定义或生成的该一次调度中的T个传输块和S最小时间调度单元的映射关系，确定出一次调度中的传输块数以及每个传输块映射的最小时间调度单元。
可选的，在一些实施例中，该N个调度规则中的每个调度规则可以仅包括一次调度的传输块个数T。在这些实施例中，一次调度的传输块个数T可以整除S也可以不整除S。同时，在这些实施例中，一次调度的T个传输块和S个最小时间调度单元有如下映射关系：该T个传输块中的每个传输块映射到S个最小时间调度单元中的一个最小时间调度单元；或者，T个传输块中的每个传输块映射到该S个最小时间调度单元；或者，若S/T大于1且小于S的正整数，则该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，其中，S＝S t*T，S t为大于1且小于S的整数；若S/T不为正整数，则该T个传输块中的第一个传输块映射到a+b个最小时间调度单元，该T个传输块中除该第一个传输块以外的每一个传输块映射到a个最小时间调度单元，其中，a和b均为正整数，b小于T，且S＝a*T+b。
更进一步，该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，包括：该T个传输块中的第t个传输块映射到该S个最小时间调度单元中的第(t-1)*S t+1个最小时间调度单元至第t*S t个最小时间调度单元，其中t＝1,…,T，S t＝S/T。
例如，假设一次调度中的最小时间调度单元数目为4。若目标调度规则包括一次调度中的传输块数目为2，则该2个传输块中的第一个传输块映射到第一个最小时间调度单元和第二个最小时间调度单元，该2个传输块中的第二个传输块映射到第三个最小时间调度单元和第四个最小时间调度单元。若目标调度规则包括一次调度中的传输块数目为3，则3个传输块中的第一个传输块映射到第一个最小时间调度单元和第二个最小时间调度单元，3个传输块中的第二个传输块和第三个传输块分别映射到第三个最小时间调度单元和 第四个最小时间调度单元。
该网络侧设备可以保存或预定义或生成该一次调度的T个传输块和S最小时间调度单元的映射关系。这样，该网络侧设备可以根据目标调度规则中包括的一次调度的传输块个数和该网络侧设备保存或预定义或生成的该一次调度的T个传输块和S最小时间调度单元的映射关系，确定出每个传输块映射的最小时间调度单元。
类似的，该终端设备也可以保存或预定义或生成该一次调度的T个传输块和S最小时间调度单元的映射关系。该终端设备可以根据目标调度规则中包括的一次调度的传输块个数和该终端设备保存或预定义或生成的该一次调度的T个传输块和S最小时间调度单元的映射关系，确定出每个传输块映射的最小时间调度单元。
可选的，在一些实施例中，该N个调度规则中的每个调度规则可以仅包括一次调度中的传输块个数T。在这些实施例中，一次调度中传输块个数T可以整除S也可以不整除S。同时，在这些实施例中，一次调度中的T个传输块和S个最小时间调度单元有如下映射关系T个传输块中的每个传输块映射到S个最小时间调度单元中的一个最小时间调度单元；或者，T个传输块中的每个传输块映射到该S个最小时间调度单元；或者，若S/T大于1且小于S的正整数，则该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，其中，S＝S t*T，S t为大于1且小于S的整数；若S/T不为正整数，则该T个传输块中的第T个传输块映射到a+b个最小时间调度单元，该T个传输块中除该第T个传输块以外的每一个传输块映射到a个最小时间调度单元，其中，a和b均为正整数，b小于T，且S＝a*T+b。
更进一步，该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，包括：该T个传输块中的第t个传输块映射到该S个最小时间调度单元中的第(t-1)*S t+1个最小时间调度单元至第t*S t个最小时间调度单元，其中t＝1,…,T，S t＝S/T。

可选的，在另一些实施例中，该N个调度规则中的每个调度规则可以仅包括一次调度 的传输块个数T。在这些实施例中，一次调度的传输块个数T可以整除S也可以不整除S。在这些实施例中，一次调度的T个传输块和S个最小时间调度单元有如下映射关系：该T个传输块中的每个传输块映射到S个最小时间调度单元中的一个最小时间调度单元；或者，T个传输块中的每个传输块映射到该S个最小时间调度单元；或者，若S/T大于1且小于S的正整数，则该T个传输块中的每个传输块映射到该S个最小时间调度单元中连续的S t个最小时间调度单元，其中，S＝S t*T，S t为大于1且小于S的整数；若S/T不为正整数，则该T个传输块中的第一个传输块映射到a+b个最小时间调度单元，该T个传输块中的第T个传输块映射到a+c个最小时间调度单元，该T个传输块中除该第一个传输块和该第T个传输块以外的每一个传输块映射到a个最小时间调度单元，其中，a、b和c均为正整数，b+c小于T，且S＝a*T+b+c。更进一步，若(S-a*T)能够被2整除，则b与c相等。若(S-a*T)不够被2整除，则该预设规则还可以包括b＝c+1，或者该预设调度规则还可以包括c＝b+1。
例如，假设一次调度中的最小时间调度单元数目为8。若目标调度规则包括一次调度中的传输块数目为4，则4个传输块中的每个传输块映射到两个最小时间调度单元。若目标调度规则包括一次调度中的传输块数目为3，则3个传输块中的第一个传输块映射到第一个最小时间调度单元至第三个最小时间调度单元，3个传输块中的第二个传输块映射到第四个最小时间调度单元和第五个最小时间调度单元，3个传输块中的第三个传输块映射到第六个最小时间调度单元至第8个最小时间调度单元。假设该预设调度规则包括：若(S-a*T)不够被2整除，则b＝c+1。若目标调度规则包括一次调度中的传输块数目为5，则5个传输块中的第一个传输块映射到第一个最小时间调度单元至第三个最小时间调度单元，5个传输块中的第二个传输块至第四个传输块分别映射到第四个最小时间调度单元至第六个最小时间调度单元，5个传输块中的第五个传输块映射到第七个最小时间调度单元和第八个最小时间调度单元。假设该预设规则包括：若(S-a*T)不能够被2整除，则c＝b+1，则5个传输块中的第一个传输块映射到第一个最小时间调度单元和第二个最小时间调度单元，5个传输块中的第二个传输块至第四个传输块分别映射到第二个最小时间调度单元至第五个最小时间调度单元，5个传输块中的第五个传输块映射到第六个最小时间调度单元至第八个最小时间调度单元。
该网络侧设备可以保存或预定义或生成该一次调度中的T个传输块和S最小时间调度单元的映射关系。这样，该网络侧设备可以根据目标调度规则中包括的一次调度中的传输块个数和该网络侧设备保存或预定义或生成的该一次调度的T个传输块和S最小时间调度单元的映射关系，确定出每个传输块映射的最小时间调度单元。
类似的，该终端设备也可以保存或预定义或生成该一次调度中的T个传输块和S最小时间调度单元的映射关系。该终端设备可以根据目标调度规则中包括的一次调度中的传输块个数和该终端设备保存或预定义或生成的该一次调度的T个传输块和S最小时间调度单元的映射关系，确定出每个传输块映射的最小时间调度单元。
虽然在上述几个实施例中的调度规则可以仅包括一次调度中的传输块数T或一次调度中的一个传输块映射的最小时间调度单元数，该调度规则也可以包括一次调度的T个传输块和S个最小时间调度单元的映射关系。可以理解的是，在调度规则包括一次调度的T个传输块和S个最小时间调度单元的映射关系的情况下，该终端设备和该网络侧设备可以 预先保存或预定义一次调度的T个传输块和S个最小时间调度单元的映射关系，也可以不保存或预定义一次调度的T个传输块和S个最小时间调度单元的映射关系。
此外，在一些实施例中，该N个调度规则中的每个调度规则也可以仅包括一次调度的T个传输块和S个最小时间调度单元的映射关系。这样，该终端设备可以直接根据该目标传输规则确定出T个传输块和S个最小时间调度单元的映射关系，而无需保存或预定义或生成T个传输块和S个最小时间调度单元的映射关系并根据接收到的目标调度规则中包括的一次调度的传输块数和/或一次调度的一个传输块映射的最小时间调度单元数确定出每个传输块映射的最小时间调度单元。
可选的，在另一些实施例中，每个传输块映射的最小时间调度单元数目可以相同也可以不同，且可以根据需要确定出每个传输块映射的最小时间调度单元。这时，该调度规则包括一次调度的T个传输块和S个最小时间调度单元的映射关系。
例如，表13是另一个调度规则的示意。表13中假设一次调度的最小时间调度单元数目为4。

表13
如表13所示，在传输块数目为2的情况下，一个传输块可以映射到两个最小时间调度单元，也可以映射到三个最小时间调度单元或者一个最小时间调度单元。
在此情况下，该调度规则可以包括一次调度的传输块数目T以及一次调度的T个传输块和S个最小时间调度单元的映射关系。或只包括一次调度的T个传输块和S个最小时间调度单元的映射关系。
可选的，在一些实施例中，若该调度规则包括一次调度的传输块个数T、一次调度的一个传输块映射的最小时间调度单元数目，和一次调度的T个传输块和S个最小时间调度单元的映射关系中的一个或多个信息的情况下，该目标调度规则指示信息可以同时指示该目标调度规则包括的所有信息。
具体地，该终端设备和该网络侧设备可以保存或预定义或生成N个调度规则，每个调度规则有一个对应的调度规则序号。在此情况下，该网络侧设备仅需要指示该终端设备该目标调度规则的调度规则序号，该终端设备可以根据该调度规则序号确定该调度规则的具体信息。可以理解的是，该网络侧设备和该终端设备所保存或预定义或生成的调度规则序号和调度规则的对应关系是相同的。
例如，以表13为例，该终端设备和该网络侧设备都可以保存或预定义或生成如表13 所示的调度规则序号和调度规则的对应关系。该目标调度规则指示信息只需要指示目标调度规则对应的调度规则序号即可。
可选的，在另一些实施例中，若该调度规则包括一次调度中的传输块个数T、一个传输块映射的最小时间调度单元数目，和T个传输块和S个最小时间调度单元的映射关系中的至少两个信息，该目标调度规则指示信息可以分开指示该至少两个信息。
例如，该网络侧设备可以利用指定的控制信息(即子载波间隔、每个最小时间调度单元占用的符号数目、DCI格式、MCS、循环冗余校验码，和分配的资源块数目等)指示一次调度中的传输块数目，然后利用其它字段指示传输块与最小时间调度单元的映射关系。例如，该网络侧设备可以在控制信令中增加一些专用字段来指示传输块与最小时间调度单元的映射关系，该网络侧设备还可以利用控制信令中的与一些冗余字段来指示该传输块与最小时间调度单元的映射关系。
例如，以DCI为例，DCI中的有些域每个传输块都有一个对应的字段。假设一次调度中可调度的传输块数目为X且该目标调度规则中调度的传输块数目为Y(X大于Y且X与Y均为正整数)，则有X-Y个传输块的对应的字段是冗余字段。在此情况下，可以利用该X-Y个传输块对应的字段来指示该目标调度规则。此外，可以理解的是，在可用的传输块数目与该目标调度规则中的传输块数目相等的情况下，没有冗余的传输块。在此情况下，可以有一个默认的传输块与最小时间调度单元的映射关系。如果该目标调度规则中的传输块数目等于该可用的传输块数目，则该传输块与最小时间调度单元的映射关系为该默认的映射关系。
假设一次调度中最多可调度的传输块数目为4。若一次调度中调度的传输块数目为2，则可以利用剩余2个未调度的传输块对应的字段来指示传输块与最小时间调度单元的映射关系。若该目标调度规则中一次调度的传输块数目为4，则可以确定传输块与最小时间调度单元的映射关系为默认的映射关系，即一个传输块与一个最小时间调度单元映射。
可选的，在一些实施例中，每个传输块映射的调度单元数目可以与传输块的属性相关。该传输块的属性是指该传输块是初传传输块还是重传传输块。各传输块灵活时域资源分配可以使得各传输块根据所需调度资源个数,进而获得性能增益。
可选的，在一些实施例中，重传传输块的映射规则为：每个重传传输块映射到一个最小时间调度单元。每个初传传输块可以映射到一个或多个最小时间调度单元。此外，该T个传输块中最多可以包括一个初传传输块。这样，通过重传采用更少的资源，可以避免资源浪费以获得吞吐量和频谱效率的增益。
假设该T个传输块均为重传传输块，则每个传输块映射到一个最小时间调度单元。假设该T个传输块中包括1个初传传输块和T-1个重传传输块(T不等于1)，则该T-1个重传传输块与S个最小时间调度单元中的前T-1个最小时间调度单元一一对应，即该T-1个重传传输块中的第t个重传传输块映射到该S个最小时间调度单元中的第t个最小时间调度单元，其中t＝1,…,T-1。该初传传输块映射到该S个最小时间调度单元剩余的传输块。假设该T个传输块中不包括重传传输块，则T等于1且该T个传输块映射到该S个传输块上。
例如，若T＝1且S＝4，则该T个传输块中可以包括1个初传传输块，该初传传输块映射到该S个最小时间调度单元。
再如，若T＝2且S＝4，则该T个传输块中可以包括1个初传传输块和1个重传传输块。该重传传输块映射到该S个最小时间调度单元中的第一个最小时间调度单元，该初传传输块映射到该S个最小时间调度单元的第二至第四个最小时间调度单元。
又如，若T＝3且S＝4，则该T个传输块中可以包括1个初传传输块和2个重传传输块。第一个重传传输块映射到该S个最小时间调度单元中的第一个最小时间调度单元，第二个重传传输块映射到该S个最小时间调度单元中的第二个最小时间调度单元，该初传传输块映射到该S个最小时间调度单元第三个最小时间调度单元和第四个最小时间调度单元。
又如，若T＝4且S＝4，则该T个传输块中可以包括1个初传传输块和3个重传传输块，或者，该T个传输块也可以包括4个重传传输块。若该T个传输块中包括1个初传传输块可3个重传传输块，则第一个重传传输块映射到该S个最小时间调度单元中的第一个最小时间调度单元，第二个重传传输块映射到该S个最小时间调度单元中的第二个最小时间调度单元，第三个重传传输块映射到该S个最小时间调度单元中的第三个最小时间调度单元，该初传传输块映射到该S个最小时间调度单元第四个最小时间调度单元。若该T个传输块包括4个重传传输块，则第一个重传传输块映射到该S个最小时间调度单元中的第一个最小时间调度单元，第二个重传传输块映射到该S个最小时间调度单元中的第二个最小时间调度单元，第三个重传传输块映射到该S个最小时间调度单元中的第三个最小时间调度单元，第四个重传传输块映射到该S个最小时间调度单元中的第四个最小时间调度单元。
该网络侧设备可以利用与每个传输块对应的字段来指示该终端设备传输块的属性。该终端设备可以根据传输块的属性确定出传输块和最小时间调度单元的映射关系。具体地，DCI中可以有T个比特的NDI，每个比特用于指示一个传输块是否为重传传输块。例如，比特值为1或者0或出现了翻转(取决于协议规定，下面例子中假设比特值为1代表初传，比特值为0代表重传)，则表示对应的传输块为初传传输块，否则表示对应的传输块为重传传输块。该终端设备可以根据该T个bit确定出每个传输块的属性，并根据每个传输块的属性确定出每个传输块映射的最小时间调度单元。
例如，若T＝4且T个比特为001x，其中x表示该位比特的值可以为1也可以为0。该终端设备在读取到该T个比特后，可以确定出四个传输块中的第一个传输块和第2个传输块为重传传输块，第3个传输块为初传传输块。这样，该终端设备可以确定出S个最小时间调度单元的前两个最小时间调度单元分别为该两个重传传输块映射的最小时间调度单元，该S个最小时间调度单元中剩余的最小时间调度单元为该初传传输块映射的最小时间调度单元。
图2是一种传输过程中调度规则切换的示意图。图2示出了连续的六次调度。图2所示的S1至S24表示24个最小时间调度单元。图2所示的一次调度的最小时间调度单元数目为4。在连续的六次调度中，前五次调度中的传输块或进程为初传，每次调度中的传输块数目为1，即表1中的调度规则1(或表2中的调度规则4)。具体地，进程0映射到最小时间调度单元S1至S4，进程1映射到最小时间调度单元S5至S8，进程2映射到最小时间调度单元S9至S12，进程3映射到最小时间调度单元S13至S16，进程4映射到最小时间调度单元S17至S20，其中，进程0至进程4中的每个进程为一个初传传输块。发送端设备在接收到接收端设备发送的否定(non acknowledgment，NACK)指示后，确定 有进程或传输块需要重传。如图2所示，在第六次调度中一次调度4个传输块，即表1中调度规则3(或表2中的调度规则1)。该4个传输块可以为四个重传进程(或称重传传输块)，该四个重传进程的数据分别映射到四个最小时间调度单元。换句话说，在第六次调度中的四个重传进程中的每个进程或传输块仅映射到一个最小时间调度单元。当然，在另一些实施例中，第六次调度中4个传输块也可以包括重传传输块和初传传输块。例如，一个重传传输块映射到最小时间调度单元S21，三个初传传输块分别映射到最小时间调度单元S22至S24。在另一些实施例中，第六次调度中4个传输块可以都是初传传输块。在另一些实施例中，前5次调度中也可以存在重传传输块。注意每次调度的最小时间调度单元数目可以动态变化，不限定为4。
图3是另一种传输过程中调度规则切换的示意图。图3示出了连续的六次调度。图3所示的S1至S24表示24个最小时间调度单元。图3所示的一次调度的最小时间调度单元数目为4。在连续的六次调度中，前五次调度中的传输块为初传传输块，每次调度中的传输块数目为1，即表1中的调度规则1(或表13中的调度规则8)。具体地，进程0映射到最小时间调度单元S1至S4，进程1映射到最小时间调度单元S5至S8，进程2映射到最小时间调度单元S9至S12，进程3映射到最小时间调度单元S13至S16，进程4映射到最小时间调度单元S17至S20，其中，进程0至进程4中的每个进程为一个初传传输块。发送端设备在接收到接收端设备发送的NACK指示后，确定有一个进程或传输块需要重传。在此情况下，在第六次调度中一次调度2个传输块，即表13中调度规则3。该2个传输块可以是两个重传进程(或称重传传输块)，该两个重传进程中的第一个重传进程映射到一个最小时间调度单元S21，另一个重传进程映射到三个最小时间调度单元S22至S24。当然，在另一些实施例中，第六次调度中2个传输块也可以包括重传传输块和初传传输块。例如，一个重传传输块映射到最小时间调度单元S21，一个初传传输块映射到最小时间调度单元S22至S24。在另一些实施例中，第六次调度中2个传输块可以都是初传传输块。在另一些实施例中，前5次调度中也可以存在重传传输块。注意每次调度的最小时间调度单元数目可以动态变化，不限定为4。
可选的，作为另一些实施例，重传传输块的映射规则为：重传传输块可以映射的最小时间调度单元数目多于初传传输块映射的最小时间调度单元数目。这样可以降低通信时延，保证通信可靠性，使得传输块可以尽快被译码成功。
可选的，作为另一些实施例，重传传输块的映射规则为：重传传输块可以映射的最小时间调度单元数目和初传传输块映射的最小时间调度单元数目相同。
网络侧设备可以支持上述三种重传传输块的映射规则，并且根据需要在两者之间进行切换。上述技术方案可以根据需要调整重传传输块映射的最小时间调度单元数目和初传传输块映射的在最小时间调度单元数目，这样可以获得性能增益。
虽然以上所有实施例都是以1个最小时间调度单元最多只承载1个传输块数据的情况举例。考虑到5G带宽(比如80MHz或者更大)和快速傅里叶变换采样数限制(比如2048)，本申请也可以通过1个最小时间调度单元上承载多个传输块的数据以实现大带宽通信。1个传输块的数据可以承载在1个或多个子带上。同样的，通过1个DCI调度多个传输块，可以节省信令开销，比如许多域可以所有传输块共享，有些域可以每个传输块特定。例如NDI域等可以为每个传输块的特定域。再如，MCS可以一个值。每个传输块根据该MCS 和该传输块特定的MCS偏移值确定该传输块的MCS值。综上所述，一次调度中的传输块数目T可以大于最小时间调度单元数目，以节省控制开销。
图4是一次调度的多个传输块映射到一个最小时间调度单元的示意图。如图4所示的一次调度包括一个最小时间调度单元S1和四个传输块。一次调度的4个传输块分别映射到一个最小时间调度单元在频域上的四个频域资源。这四个频域资源可以是连续的也可以是不连续的，四个频域资源大小可以相同也可以不同。
图5是另一个一次调度的多个传输块映射到一个最小时间调度单元的示意图。如图5所示的一次调度包括一个最小时间调度单元S1和两个传输块。一次调度的两个传输块中的每个传输块映射到一个最小时间调度单元在频域上的两个频域资源。这四个频域资源可以是连续的也可以是不连续的，四个频域资源大小可以相同也可以不同。
为方便描述，以下将一个最小时间调度单元最多承载一个传输块数据的情况称为时分复用，即前文所述所有实施例都是时分复用场景；将一个最小时间调度单元承载两个或两个以上传输块数据的情况称为频分复用。频分复用的具体实施例与上述时分复用的实施例类似，在此就不必赘述。
为了便于理解频分复用和时分复用的区别，下面将结合图6和图7对时分复用进行描述。
图6是一次调度的多个传输块映射在多个最小时间调度单元的示意图。如图6所示的一次调度包括四个最小时间调度单元S1至S4和四个传输块，四个传输块分别映射在四个最小时间调度单元上。
图7是另一次调度的多个传输块映射在多个最小时间调度单元的示意图。如图7所示的一次调度包括四个最小时间调度单元S1至S4和两个传输块。两个传输块映射在四个最小时间调度单元。具体地，两个传输块中的第一个传输块映射在最小时间调度单元S1和S2，两个传输块中的第二个传输块映射在最小时间调度单元S3和S4。
在一些实施例中，可以将时分复用和频分复用结合。
图8是时分复用和频分复用结合的示意图。如图8所示的一次调度包括两个最小时间调度单元S1和S2和两个传输块。一次调度的两个传输块分别映射在两个最小时间调度单元的不同频域。可以看出，图4所示的实施例中，一次调度的两个传输块中的每个传输块都映射到了一次调度的两个最小时间调度单元。
图9是时分复用和频分复用结合的示意图。如图9所示的一次调度包括三个最小时间调度单元S1至S3和四个传输块。四个传输块中的传输块1和传输块2分别映射在最小时间调度单元S1的不同频域。传输块3映射在最小时间调度单元S2和S3且传输块3映射的最小时间调度单元的频域资源与传输块1映射的最小时间调度单元的频域资源相同。类似的，传输块4映射在最小时间调度单元S2和S3且传输块4映射的最小时间调度单元的频域资源与传输块2映射的最小时间调度单元的频域资源相同。同时，传输块3映射的两个最小时间调度单元与传输块4映射的两个最小时间调度单元是相同的最小时间调度单元。传输块3映射在这两个最小时间调度单元的频域资源与传输块4映射在这两个最小时间调度单元的频域资源是不同的。
此外，在频分复用和时分复用结合的情况下，每个频域资源的一次调度的T个传输块和S个最小时间调度单元的映射关系与时分复用场景中的一次调度的T个传输块和最小时 间调度单元的映射关系相同，在此就不必赘述。
可选的，在另一些实施例中，初传传输块可以采用时分复用的方式，重传传输块可以采用频分复用的方式。
图10是一个利用频分复用传输初传传输块和重传传输块的示意图。图10所示的S1至S6表示6个最小时间调度单元。如图10所示，在连续的六次调度中，前五次调度中的传输块均为初传传输块且每个传输块映射到1个最小时间调度单元，可定义为调度规则1。具体地，进程0映射到最小时间调度单元S1，进程1映射到最小时间调度单元S2，进程2映射到最小时间调度单元S3，进程3映射到最小时间调度单元S4，进程4映射到最小时间调度单元S5，其中，进程0至进程4中的每个进程为一个初传传输块。发送端设备在接收到接收端设备发送的NACK指示后，确定进程或传输块需要重传。在此情况下，在第六次调度中可以调度2个传输块，可定义为调度规则2。所述2个传输可以包括重传进程(或称重传传输块)，该两个重传进程采用频分复用的方式映射到一个最小时间调度单元S6。当然，在另一些实施例中，第六次调度包括的两个传输块可以分别为重传传输块和初传传输块。重传传输块和初传传输块采用频分复用的方式映射到一个最小时间调度单元S6。或者两个传输块都为初传传输块。在另一些实施例中，前5次调度中也可以存在重传传输块。注意每次调度的最小时间调度单元数目可以动态变化，不限定为1。
为了方便描述图2至图10所示的实施例中仅示出了传输块占用的资源，并非示出控制信号占用的资源。
注意：本文至此的所有实施例考虑的都是非空分复用场景，即一次调度的传输块数是针对1个时频资源上只承载1个码字或者1个传输块的数据的配置场景。在此场景下，一次调度的多个传输块可以采用时分复用的方式映射到多个最小时间调度单元，或者，一次调度的多个传输块可以采用频分复用的方式映射到一个最小时间调度单元。
此外，以上所有实施例是网络侧设备确定的传输模式为非空分复用的传输模式的实施例。也就是说，以上实施例中的一次调度的T个传输块与S个最小时间调度单元的映射关系、一次调度的传输块数目等都是针对非空分复用场景而言。所谓非空分复用的传输模式为1个时频资源上只承载1个码字或者1个传输块的数据的传输方式。
在网络侧设备确定的传输模式为空分复用传输模式的情况下，假设1个时频资源上承载N c个码字或者N c个传输块的数据，其中N c为大于或等于2的正整数(在此，本申请简称该传输模式场景为N c个码字或N c条流场景，Nc为1个时频资源上空分复用的码字数或进程数或传输块数)。在此情况下，一次调度的总的传输块个数为N c*T，其中N c个码字或N c条流中的每个码字或每条流的一次调度的传输块个数为T。相同的，该场景下一次调度的最小时间调度单元个数为S。
在上述空分复用场景中，一次调度的N c*T个传输块和S个最小时间调度单元的映射关系即为一次调度的N c个码字或N c条流中的每个码字或每条流的T个传输块和S个最小时间调度单元的映射关系。每个码字或每条流上的一次调度的T个传输块与S个最小时间调度单元的映射关系与非空分复用场景中一次调度的T个传输块与S个最小时间调度单元的映射关系相同。或者，换句话说，在非空分复用场景中的一次调度的T个传输块与S个最小时间调度单元的映射关系为空分复用场景中一次调度的每个码字或每条流上的T个传输块与S个最小时间调度单元的映射关系。在非空分复用该场景中的一次调度的传输 块数目T为空分复用场景中一次调度的每个码字或每条流的传输块数目T。因此，该一次调度的每个码字或每条流上的T个传输块与S个最小时间调度单元的映射关系的具体实施例可以参照前文所有实施例非空分复用该场景中一次调度的T个传输块与S个最小时间调度单元的映射关系的具体实施例，在此就不必赘述。
此外，空分复用场景中一次调度的任意两个码字或两条流的T个传输块与S个最小时间调度单元的映射关系相同。
空分复用场景中确定目标调度规则的方法以及指示目标调度规则的方法与非空分复用场景中相同，具体可以参见上述实施例，在此就不必赘述。
此外，在一些实施例中，网络侧设备向该终端设备发送的DCI包括传输块进程域，该传输块进程域用于指示所述T个传输块中每个传输块的进程号。该传输块进程域的长度为w比特，该w比特可以指示T*2 w个进程号，T表示一次调度中的传输块数目。
例如，在一个传输块映射到1个最小时间调度单元的情况下，假设一次调度中有4个最小时间调度单元，则处理反馈的时延也为4个最小时间调度单元。在此情况下，需要8个进程。该DCI中可以包括1比特传输块进程域。该终端设备可以通过以下方式确定进程号：
P_Num＝i*T+j,(公式1.1)
其中，P_Num表示进程号，i表示该传输块进程域的取值，T表示一次调度中的传输块数目，j＝1,…,T，在第一次调度中i＝0，在第二次调度中i＝1。这样，该终端设备可以利用公式1.1确定出每次调度中的每个传输块的进程号。利用上述技术方案，在需要指示8个进程的情况下，可以将用于指示进程号的指示字段长度从3比特缩短为1比特，从而可以节省DCI开销。
上述实施例仅是为了帮助本领域技术人员更好地理解本申请实施例的技术方案，而并非是对本申请实施例技术方案的限定。具体实施过程中进程数、帧格式、一次调度的最小时间调度单元数目、重传传输块和初传传输块需要的资源数，频域资源是否连续，每次调度的频域资源数、层数、码字数、码字映射的层数、流数、天线配置、传输模式等都可以变化，本文不做限定。
进一步，上述实施例所讨论的场景是网络侧设备与终端设备通信的场景。上述技术方案还可以应用于终端到终端(device to device，D2D)的通信。
D2D通信包括由网络侧设备控制的D2D通信(以下简称第一类D2D通信)和不受网络侧设备控制的D2D通信(以下简称第二类D2D通信)。
在第一类D2D通信场景中，网络侧设备可以负责从N个调度规则中确定目标调度规则，并将该目标调度规则指示给进行D2D通信的终端设备。在第一类D2D通信场景中，网络侧设备确定该目标调度规则的方式与网络侧设备与终端设备通信的场景中网络侧设备确定目标调度规则的方式相同，在第一类D2D通信场景中，网络侧设备指示该目标调度规则的方式与网络侧设备与终端设备通信的场景中网络侧设备指示目标调度规则的方式相同在此就不必赘述。进行D2D通信的终端设备可以根据该网络侧设备指示的目标调度规则进行通信。
在第二类D2D通信场景中，进行D2D通信的终端设备中可以包括一个主终端设备。该主终端设备负责从N个调度规则中确定目标调度规则，并将该目标调度规则指示给其他 D2D通信设备。第二类D2D通信场景中，主终端设备确定该目标调度规则的方式与网络侧设备与终端设备通信的场景中网络侧设备确定目标调度规则的方式相同，在第二类D2D通信场景中，主终端设备指示该目标调度规则的方式与网络侧设备与终端设备通信的场景中网络侧设备指示目标调度规则的方式相同在此就不必赘述。进行D2D通信的终端设备可以根据该主终端设备指示的目标调度规则进行通信。
