技术领域
本申请涉及通信技术领域，尤其涉及一种通信的方法及装置。
背景技术
在无线通信网络中，一个传输块(transmission block，TB)对应的数据收发通常可以占用一个发送时间间隔(transmission time interval，TTI)。例如在长期演进(long term evolution，LTE)网络中，一个TB对应的数据收发可以占用一个子帧。又例如，在新空口(new radio，NR)网络中，一个TB对应的数据收发可以占用一个时隙。上述机制的主要问题是，TB对应的数据收发在时间上占用的时域资源不够灵活，从而无法依据TB的数据量大小更加合理地利用时域资源。因此，如何为数据收发设计更加灵活的时域资源使用方式以提高数据传输效率，成为亟需解决的问题。

具体实施方式
本申请实施例提供的通信的方法及装置可以应用于通信系统中。如图1示出了一种通信系统结构示意图。该通信系统中包括一个或多个网络设备(清楚起见，图中示出网络设备10和网络设备20)，以及与该一个或多个网络设备通信的一个或多个终端设备。图1中所示终端设备11和终端设备12与网络设备10通信，所示终端设备21和终端设备22与网络设备20通信。可以理解的是，网络设备和终端设备也可以被称为通信设备。
本发明实施例描述的技术可用于各种通信系统，例如2G，3G，4G，4.5G，5G通信系统，多种通信系统融合的系统，或者未来演进网络。例如长期演进(long term evolution，LTE)系统，新空口(new radio,NR)系统，无线保真(wireless-fidelity，WiFi)系统，以及第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的蜂窝系统等，以及其他此类通信系统。
图2示出了通信系统的一种可能的架构举例示意图，如图2所示无线接入网(radio access network，RAN)中的网络设备是集中单元(centralized unit，CU)和分布单元(distributed unit,DU)分离架构的基站(如gNodeB或gNB)。RAN可以与核心网相连(例如可以是LTE的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如分组 数据汇聚层协议(packet data convergence protocol，PDCP)层及无线资源控制(radio resource control,RRC)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(media access control，MAC)层，物理(physical)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。图2所示的网络架构可以应用于5G通信系统，其也可以与LTE系统共享一个或多个部件或资源。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现，也可以进一步将控制面(CP)和用户面(UP)分离，即CU的控制面(CU-CP)和用户面(CU-UP)可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。
可以理解的是，本申请中提供的实施例也适用于CU和DU不分离的架构。
本申请中，网络设备可以是任意一种具有无线收发功能的设备。包括但不限于：LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，NR中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point,TRP)，3GPP后续演进的基站，WiFi系统中的接入节点，无线中继节点，无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，中继站，或，气球站等。多个基站可以支持上述提及的同一种技术的网络，也可以支持上述提及的不同技术的网络。基站可以包含一个或多个共站或非共站的TRP。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、CU，和/或，DU。网络设备还可以是服务器，可穿戴设备，或车载设备等。以下以网络设备为基站为例进行说明。所述多个网络设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端设备进行通信，也可以通过中继站与终端设备进行通信。终端设备可以与不同技术的多个基站进行通信，例如，终端设备可以与支持LTE网络的基站通信，也可以与支持5G网络的基站通信，还可以支持与LTE网络的基站以及5G网络的基站的双连接。
终端是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴终端设备等等。本申请的实施例对应用场景不做限定。终端有时也可以称为终端设备、用户设备(user equipment，UE)、 接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、终端设备、无线通信设备、UE代理或UE装置等。终端也可以是固定的或者移动的。
在无线通信网络中，一个传输块(transmission block，TB)对应的数据收发通常可以占用一个发送时间间隔(transmission time interval，TTI)。例如在长期演进(long term evolution，LTE)网络中，一个TB对应的数据收发可以占用一个子帧。又例如，在新空口(new radio，NR)网络中，一个TB对应的数据收发可以占用一个时隙。上述机制的主要问题是，TB对应的数据收发在时间上占用的时域资源不够灵活，从而无法依据TB的数据量大小更加合理地利用时域资源。因此，如何为数据收发设计更加灵活的时域资源使用方式以提高数据传输效率，成为亟需解决的问题。
本申请实施例提供的方法中，通信设备能够确定出时间单元聚合中承载不同数据的不同时域资源，因此能够依据数据传输的实际需求灵活调整数据收发占用的时域资源，从而提高了数据传输效率。
下面以具体实施例结合附图对本申请的技术方案进行详细说明。下述实施例和实施方式可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。应理解，本申请中所解释的功能可以通过独立硬件电路、使用结合处理器/微处理器或通用计算机而运行的软件、使用专用集成电路，和/或使用一个或多个数字信号处理器来实现。当本申请描述为方法时，其还可以在计算机处理器和被耦合到处理器的存储器中实现。
图3为本申请实施例提供的一种通信方法的流程示意图，该方法可以由终端执行。如图3所示，该实施例的方法可以包括：

310部分：根据所述控制信息确定至少一个第一子时间单元和至少一个第二子时间单元，所述至少一个第一子时间单元和所述至少一个第二子时间单元包括在至少一个时间单元中。可以理解，所述至少一个时间单元可以由所述至少一个第一子时间单元和所述至少一个第二子时间单元构成，或者，所述至少一个时间单元除所述至少一个第一子时间单元和所述至少一个第二子时间单元以外还包括其他的子时间单元。可选地，所述时间单元为时隙，所述子时间单元为时隙或符号(也可称为时域符号)；或者，所述时间单元为子帧，所述子时间单元为子帧、时隙、或符号；或者，所述时间单元为帧，所述子时间单元为帧、子帧、时隙、或符号。本申请实施例以及其他实施例中的时间单元或子时间单元也可以理解为一种时域资源。

通过上述实施例描述的方法，终端能够在至少一个时间单元中确定出承载不同数据的不同时域资源，因此能够依据数据传输的实际需求灵活调整数据收发占用的时域资源，从而提高了数据传输效率。
在上述控制信息的一种可选的实施方式中，上述控制信息用于指示所述至少一个第一子时间单元的位置，或者，上述控制信息用于指示所述至少一个第二子时间单元的位置。可以理解，该实施方式可适用于当所述至少一个时间单元由所述至少一个第一子时间单元和所述至少一个第二子时间单元构成时。在310部分中，根据该控制信息指示的所述至少一个第一子时间单元的位置可确定出所述至少一个第一子时间单元，又由于所述至少一个时间单元由所述至少一个第一子时间单元和所述至少一个第二子时间单元构成，因此可在所述至少一个时间单元中确定出所述至少一个第二子时间单元。或者，在310部分中，根据该控制信息指示的所述至少一个第二子时间单元的位置可确定出所述至少一个第二子时间单元，又由于所述至少一个时间单元由所述至少一个第一子时间单元和所述至少一个第二子时间单元构成，因此可在所述至少一个时间单元中确定出所述至少一个第一子时间单元。上述控制信息指示的可以是所述至少一个第一子时间单元或所述至少一个第二子时间单元的位置，也可以是与所述位置对应的索引、编号、或枚举参数。
例如以图4示意的一种时域资源为例，图4中以被标识成#0、#1、#2、和#3的四个时间单元为上述至少一个时间单元、被标识成#0的一个时间单元为上述至少一个第一子时间单元、被标识成#1、#2、和#3的三个时间单元为上述至少一个第二子时间单元为例。所述控制信息指示所述至少一个第一子时间单元的位置在上述四个时间单元的第一个时间单元上，则可以根据该控制信息确定上述至少一个第一子时间单元为标识成#0的时间单元，并且上述至少一个第二子时间单元为标识成#1、#2、和#3的时间单元。或者，所述控制信息指示所述至少一个第二子时间单元的位置在上述四个时间单元的第二个、第三个和第四个时间单元上，则可以根据该控制信息确定上述至少一个第二子时间单元为标识成#1、#2、和#3的时间单元，并且上述至少一个第一子时间单元为标识成#0的时间单元。
在上述控制信息的另一种可选的实施方式中，上述控制信息用于指示所述至少一个第一子时间单元的位置和所述至少一个第二子时间单元的位置。在310部分中，根据该控制信息指示的所述至少一个第一子时间单元的位置和所述至少一个第二子时间单元的位置可确定出所述至少一个第一子时间单元和所述至少一个第二子时间单元。上述控制信息指示的可以是所述至少一个第一子时间单元和所述至少一个第二子时间单元的位置，也可以是与所述位置对应的索引、编号、或枚举参数。

又例如以图5示意的另一种时域资源为例，图5中以被标识成#0、#1、#2、#3、和#4的五个时间单元为上述至少一个时间单元、被标识成#0的一个时间单元为上述至少一个第一子时间单元、被标识成#1、#2、和#3的三个时间单元为上述至少一个第二子时间单元为例。所述控制信息指示所述至少一个第一子时间单元的位置在上述五个时间单元的第一个时间单元上，并且指示所述至少一个第二子时间单元的位置在上述五个时间单元的第二个、第三个和第四个时间单元上，则可以根据该控制信息确定上述至少一个第一子时间单元为标识成#0的时间单元，并且上述至少一个第二子时间单元为标识成#1、#2、和#3的时间单元。
在上述控制信息的另一种可选的实施方式中，上述控制信息用于指示所述至少一个第一子时间单元的数量，或者，上述控制信息用于指示所述至少一个第二子时间单元的数量。可以理解，该实施方式可适用于当所述至少一个时间单元由所述至少一个第一子时间单元和所述至少一个第二子时间单元构成时。可以理解，在这种实施方式下，所述至少一个第一子时间单元和所述至少一个第二子时间单元的位置关系(例如在时域上所述至少一个第一子时间单元在所述至少一个第二子时间单元之前，或者，在时域上所述至少一个第一子时间单元在所述至少一个第二子时间单元之后)可以是预定义的，或是由网络设备配置的。在310部分中，根据该控制信息指示的所述至少一个第一子时间单元的数量、以及所述至少一个第一子时间单元和所述至少一个第二子时间单元的位置关系，可确定出所述至少一个第一子时间单元，又由于所述至少一个时间单元由所述至少一个第一子时间单元和所述至少一个第二子时间单元构成，因此可在所述至少一个时间单元中确定出所述至少一个第二子时间单元。上述控制信息指示的可以是所述至少一个第一子时间单元或所述至少一个第二子时间单元的数量，也可以是与该数量对应的索引、编号、或枚举参数。
例如以图4示意的一种时域资源为例，并以在时域上所述至少一个第一子时间单元在所述至少一个第二子时间单元之前为例。所述控制信息指示所述至少一个第一子时间单元的数量为1，则可以根据该控制信息确定上述至少一个第一子时间单元为标识成#0的时间单元，并且上述至少一个第二子时间单元为标识成#1、#2、和#3的时间单元。或者，所述控制信息指示所述至少一个第二子时间单元的数量为3，则可以根据该控制信息确定上述至少一个第二子时间单元为标识成#1、#2、和#3的时间单元，并且上述至少一个第一子时间单元为标识成#0的时间单元。

在上述320部分的一种可选的实施方式中，所述第一数据为第一TB对应的数据，所述第二数据为第二传输块TB对应的数据。可以理解，本申请实施例中的TB包含多个数据比特，TB对应的数据可理解为对TB包含的数据比特进行预处理后的数据，所述预处理包括编码、调制、层映射、天线端口映射、或预编码中的一种或多种。以图4为例，至少一个第一子时间单元#0用于承载第一TB对应的数据，至少一个第二子时间单元#1-#3用于承载第二TB对应的数据，第一TB对应的数据可以少于第二TB对应的数据。对应地，在至少一个第一子时间单元#0上接收第一TB对应的数据，在至少一个第二子时间单元#1-#3上接收第二TB对应的数据。由于可以根据不同TB对应数据的多少灵活调整数据收发占用的时域资源，因此可以提高数据的传输效率和资源的使用效率。
在上述320部分的另一种可选的实施方式中，所述第一数据为第一混合自动重传请求(hybrid automatic repeat request，HARQ)进程对应的数据，所述第二数据为第二HARQ进程对应的数据。本申请实施例中HARQ对应的数据可理解为与HARQ进程号对应的数据，即第一数据为以第一HARQ进程号标识的数据，第二数据为以第二HARQ进程号标识的数据。以图4为例，至少一个第一子时间单元#0用于承载第一HARQ进程对应的数据，至少一个第二子时间单元#1-#3用于承载第二HARQ进程对应的数据，第一HARQ进程对应的数据可以少于第二HARQ进程对应的数据。对应地，在至少一个第一子时间单元#0上接收第一HARQ进程对应的数据，在至少一个第二子时间单元#1-#3上接收第二HARQ进程对应的数据。由于可以根据不同HARQ进程对应数据的多少灵活调整数据收发占用的时域资源，因此可以提高数据的传输效率和资源的使用效率。
在上述320部分的另一种可选的实施方式中，所述第一数据为初传数据，所述第二数据为重传数据。一个HARQ进程会对应一个新数据指示(new data indicator，NDI)值，该值使用1比特来指示传输的数据是初传数据还是重传数据。如果一个HARQ进程的NDI值与之前相比发生了变化，比如NDI的值由1变成了0，则表示传输的是初传数据，否则表示传输的是重传数据。或者对于一个HARQ进程对应的数据，没有之前的NDI，那么也可以认为该次传输的是初传数据。如果是重传数据，那么接收到的数据可以与同一HARQ进程的HARQ缓存中保存的之前接收到的数据进行合并。如果是新传数据，那么会清空所述HARQ进程的HARQ缓存。以图4为例，至少一个第一子时间单元#0用于承载初传数据，至少一个第二子时间单元#1-#3用于承载重传数据，初传数据可以少于重传 数据。对应地，在至少一个第一子时间单元#0上接收初传数据，在至少一个第二子时间单元#1-#3上接收重传数据。由于可以根据初传数据和重传数据的多少灵活调整数据收发占用的时域资源，因此可以提高数据的传输效率和资源的使用效率。

在上述320部分的另一种可选的实施方式中，所述第一数据为第一重传数据，所述第二数据为第二重传数据。以图4为例，至少一个第一子时间单元#0用于承载第一重传数据，至少一个第二子时间单元#1-#3用于承载第二重传数据，第一重传数据可以少于第二重传数据。对应地，在至少一个第一子时间单元#0上接收第一重传数据，在至少一个第二子时间单元#1-#3上接收第二重传数据。由于可以根据不同重传数据的数据多少灵活调整数据收发占用的时域资源，因此可以提高重传数据的传输效率和资源的使用效率。
在上述320部分的另一种可选的实施方式中，所述第一数据为第一冗余版本(redundancy version，RV)对应的数据，所述第二数据为第二RV对应的数据。本申请实施例中，RV可理解为用于指示数据传输所使用的冗余版本，其取值范围可以为0～3。以图4为例，至少一个第一子时间单元#0用于承载第一RV对应的数据，至少一个第二子时间单元#1-#3用于承载第二RV对应的数据，第一RV对应的数据可以少于第二RV对应的数据。对应地，在至少一个第一子时间单元#0上接收第一RV对应的数据，在至少一个第二子时间单元#1-#3上接收第二RV对应的数据。由于可以根据不同RV对应数据的多少灵活调整数据收发占用的时域资源，因此可以提高数据的传输效率和资源的使用效率。上述第一RV和第二RV可以有多种不同的实施方式。例如，上述第一RV和第二RV可以是一个TB的不同RV。再例如，上述第一RV和第二RV可以是两个TB分别对应的不同的RV。又例如，上述第一RV和第二RV可以是两个TB分别对应的相同的RV。
在上述320部分的另一种可选的实施方式中，所述第一数据为第一业务对应的数据，所述第二数据为第二业务对应的数据。以图4为例，至少一个第一子时间单元#0用于承载第一业务对应的数据，至少一个第二子时间单元#1-#3用于承载第二业务对应的数据，第一业务对应的数据可以少于第二业务对应的数据。对应地，在至少一个第一子时间单元#0上接收第一业务对应的数据，在至少一个第二子时间单元#1-#3上接收第二业务对应的数据。由于可以根据不同业务对应数据的多少灵活调整数据收发占用的时域资源，因此可以提高数据的传输效率和资源的使用效率。可选的，所述的第一业务和第二业务可以为增 强移动带宽(enhanced mobility broadband，eMBB)业务，超高可靠低时延通信(ultra-reliable low latency communication，URLLC)业务，增强现实(Augmented Reality，AR)/虚拟现实(Virtual Reality，VR)业务，或大规模机器通信(massive machine-type communications，mMTC)业务。
