Definitions

  • This application relates to the field of communication technology, and in particular, to a data transmission method and device.
  • the fifth generation mobile communication system uses high-frequency communication, that is, ultra-high frequency (>6GHz) signals are used to transmit data.
  • a major problem with high-frequency communication is that the signal energy drops sharply with the transmission distance, resulting in a short signal transmission distance.
  • high-frequency communication adopts the analog beam technology, and performs weighting processing through a large-scale antenna array to concentrate the signal energy in a small range to form an analog beam signal, thereby increasing the transmission distance.
  • Analog beam communication can solve the problem of short transmission distance of high-frequency signals, but it cannot solve another problem of high-frequency communication: high-frequency signals are easily blocked. Due to the short wavelength of the high-frequency signal and the weak diffraction ability, even small obstacles (such as vehicles and pedestrians) can easily block the high-frequency signal, greatly attenuating the signal strength.
  • the method to solve this problem is multi-beam polling transmission, that is, multiple beams are used to transmit the same data in turn, and the network device can use different beams to transmit the same data to be transmitted in adjacent multiple time slots (slots), as long as there is one beam Without being blocked, the data to be transmitted can be transmitted correctly.

Description

一种数据传输方法和设备
本申请要求于2018年12月05日提交中国国家知识产权局、申请号为201811483589.X、发明名称为“一种数据传输方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输方法和设备。
背景技术
第五代移动通信系统(5th generation，5G)采用高频通信，即采用超高频段(>6GHz)信号传输数据。高频通信的一个主要问题是信号能量随传输距离急剧下降，导致信号传输距离短。为了克服这个问题，高频通信采用模拟波束技术，通过大规模天线阵列进行加权处理，将信号能量集中在一个较小的范围内，形成模拟波束信号，从而提高传输距离。基于模拟波束通信可以解决高频信号传输距离短的问题，但却不能解决高频通信的另一个问题：高频信号容易被遮挡。由于高频信号波长短，衍射能力弱，即使较小的障碍物(如车辆，行人)也能轻易遮挡住高频信号，使得信号强度大大衰减。
解决这个问题的方法是多波束轮询传输，即采用多个波束轮流传输同一数据，网络设备可以在相邻的多个时隙(slot)采用不同波束传输同一个待传输数据，只要有一个波束没被遮挡，待传输数据就能传输正确。这样就大大降低了数据传输受障碍物遮挡的影响。采用多波束轮询传输时，网络设备在每次发送待传输数据到终端设备时都需要伴随一个下行控制信息(downlink control information，DCI)，该DCI可以携带本次数据传输的传输参数，例如传输配置编号(transmission configuration index，TCI)，时频资源，以及自动混合重传请求(hybrid automatic repeat request，HARQ)序号)等，DCI可以用于指示终端设备可以通过这些传输参数来接收数据。
但在高频通信中，DCI是通过下行控制信道(Physical downlink control channel，PDCCH)的模拟波束来传输的，由于模拟波束只能覆盖较小的范围，导致PDCCH模拟波束往往只能覆盖较少的终端设备，每次调度的终端设备数量受PDCCH的波束数量限制，如果网络设备在每次发送待传输数据到终端设备时都伴随一个DCI，会浪费DCI资源，导致其他终端设备的上行或下行传输无法进行，进而影响小区数据传输的性能。
发明内容
本申请提供了一种数据传输方法，可以使得网络设备不需要每次数据传输都采用DCI来指示传输参数，节省了DCI资源，提高了小区数据传输的性能。
本申请实施例第一方面提供一种数据传输方法，包括：网络设备确定第一信息，其中，所述第一信息用于指示待传输数据的多次传输的传输参数；网络设备向终端设备发送所述第一信息，所述网络设备根据所述第一信息向所述终端设备多次发送所述待传输数据。在一种场景中，网络设备可以在不同的传输时间单元采用不同的波束多次向终端设备传输待传输数据，同时，网络设备需要指示终端设备多次传输中每次数据传输的传输参数，进而 终端设备可以通过网络设备指示的传输参数来接收终端设备每次发送的待传输数据。
该第一方面实施例中，网络设备可以通过确定第一信息，并向终端设备发送所述第一信息来指示终端设备多次传输中每次数据传输的传输参数，该第一信息可以包括传输配置编号TCI集合，该TCI集合包括多个TCI，该多次传输所采用的TCI属于该TCI集合，每个TCI的编号可以指示一个波束信息，网络设备向终端设备发送第一信息，相当于指示终端设备多次传输对应的波束信息，终端设备在接收到第一信息后就可以知道多次传输所需要的TCI，进而通过TCI对应的波束信息来接收网络设备多次发送的待传输数据。本申请实施例中的每个TCI编号还可以指示一个参考信号天线端口，且每个参考信号天线端口与待传输数据多次传输中的一次传输对应，该参考信号天线端口与一个波束信息具有准共址(quasi-co-location，QCL)关系，终端设备在接收到TCI集合后，可以根据TCI编号与待传输数据每一次传输的对应关系，确定与每一次传输对应的参考信号天线端口，由于该参考信号天线端口与一个波束信息具有准共址(quasi-co-location，QCL)关系，进而终端设备可以根据与该参考信号天线端口具有准共址(quasi-co-location，QCL)关系的波束信息，确定与参考信号天线端口具有QCL关系的波束，并通过该波束来接收网络设备某次发送的待传输数据。
由该第一方面可见，由于第一信息指示了指示终端设备待传输数据多次传输的传输参数，终端设备可以根据该第一信息确定每个待传输数据相对应的传输参数，进而通过这些传输参数来接收待传输数据，使得网络设备不需要每次数据传输都采用DCI来指示传输参数，节省了DCI资源，提高了下行数据传输的性能。
在第一方面的一种可能设计中，数据传输方法还包括：该网络设备向该终端设备发送第二信息，该第二信息用于指示目标TCI子集，该目标TCI子集为该TCI集合的一个子集。网络设备可以通过向终端设备发送第二信息来指示终端设备采用TCI集合的一个TCI子集合作为多次传输的传输参数，该TCI子集合包括至少一个TCI，TCI子集合中的每个TCI编号与待传输数据多次传输中的一次传输对应，终端设备在接收到该TCI子集合后，可以根据TCI子集合的TCI编号与待传输数据每一次传输的对应关系，确定每一次传输对应的波束信息，进而通过波束信息对应的波束来接收网络设备某次发送的待传输数据。
本实施例中，通过向终端设备发送指示目标TCI子集的第二信息，使得网络设备可以根据实际需要指示终端设备采用TCI集合的一个TCI子集合作为多次传输的传输参数，增加了方案的灵活性。
在第一方面的一种可能设计中，数据传输方法还包括：该网络设备确定第三信息，其中，该第三信息用于指示按照该第一顺序遍历该TCI集合得到该多次传输中每一次传输所采用的TCI，该第一顺序包括：按照该TCI集合中TCI的编号循环递增的顺序；或者，按照该TCI集合中TCI的编号的循环递减的顺序；或者，按照该TCI集合中TCI的顺序。从时域的维度来看，网络设备每一次数据传输与TCI的对应关系在时域上可以按照一定的TCI编号顺序，具体的，网络设备每一次数据传输与TCI的对应关系可以在多个连续传输时间单元可以按照一定的TCI编号顺序。本实施例中，网络设备可以确定第三信息。对于网络设备而言，网络设备可以根据第三信息指示的第一顺序遍历TCI集合得到多次传输中每一 次传输所采用的TCI，并通过遍历得到的TCI多次向终端设备发送待传输数据。
在第一方面的一种可能设计中，数据传输方法还包括：该网络设备向该终端设备发送该第三信息，终端设备在接收到该第三信息后，终端设备可以根据第三信息按照该第一顺序遍历该TCI集合得到该多次传输中每一次传输所采用的TCI。
在第一方面的一种可能设计中，网络设备还可以向终端设备发送待传输数据多次传输中首次传输的TCI编号。以TCI集合是{TCI1，TCI2，TCI3，TCI4，TCI5，TCI6，TCI7，TCI8，TCI9}为例，若待传输数据多次传输中首次传输的TCI编号为TCI3，且第一顺序表示按照TCI集合中TCI的编号循环递增的顺序，则网络设备可以确定在多个连续传输时间单元待传输数据所采用的TCI按照TCI3，TCI4，TCI5，TCI6，TCI7，TCI8，TCI9的顺序。
在第一方面的一种可能设计中，第一信息中还可以包括待传输数据的传输次数。可选的，当网络设备发送待传输数据到终端设备的次数大于TCI集合或目标TCI子集中包含的TCI个数时，网络设备可以按照第一顺序遍历TCI集合或目标TCI子集得到多次传输中每一次传输所采用的TCI，且当遍历完TCI集合或目标TCI子集中的每个TCI后，重新进行TCI集合的遍历。
在第一方面的一种可能设计中，该第一信息包括传输该待传输数据的网络设备的标识。在多个网络设备向一个终端设备调度传输控制信息的场景中，第一信息除了需要指示每一次传输所采用的波束之外，还需要指示每一次传输采用的波束是哪一个网络设备发送的。具体的，可以将TCI集合中的各个TCI与一个网络设备关联，需要说明的是，在该场景下，网络设备的数量可以小于多次传输中TCI的数量，在第一信息中，可以将网络设备标识与TCI集合中的至少一个TCI关联，即可以将一个网络设备与多个TCI关联。
在第一方面的一种可能设计中，该第一信息和该第三信息封装在无线资源控制RRC中。
在第一方面的一种可能设计中，该第二信息封装在以下任一种或多种信息中：媒体接入控制控制元素MAC CE或物理下行控制信道PDCCH。
本申请实施例第二方面提供一种数据传输方法，包括：网络设备确定第四信息，其中，该第四信息用于指示待传输数据的多次传输的传输参数之间的关系；该网络设备根据该第四信息向该终端设备多次发送该待传输数据。网络设备可以根据第四信息指示的待传输数据的多次传输的传输参数之间的关系向终端设备发送待传输数据，终端设备可以通过待传输数据的多次传输的传输参数之间的关系来接收终端设备多次发送的待传输数据，终端设备可以通过协议确定待传输数据的多次传输的传输参数之间的关系，使得网络设备不需要每次数据传输都采用DCI来指示传输参数。待传输数据的多次传输的传输参数之间的关系可以是多次传输的自动混合重传请求HARQ进程序号之间的关系，也可以是多次传输的时频资源之间的关系。
在第二方面的一种可能设计中，数据传输方法还包括：该网络设备向该终端设备发送该第四信息。终端设备可以通过接收第四信息来确定待传输数据的多次传输的传输参数之间的关系。
在第二方面的一种可能设计中，该第四信息用于指示该多次传输的自动混合重传请求HARQ进程序号相同。第四信息可以指示网络设备在待传输数据的多次传输中每一次传输采 用的HARQ进程序号相同，相应的，终端在待传输数据的多次传输中每一次传输采用的HARQ进程序号相同。
在第二方面的一种可能设计中，该第四信息用于指示该待传输数据的多次传输的HARQ进程序号是循环递增的或者循环递减的。在一种场景中，本实施例中的网络设备在不同的传输时间单元通过不同的波束多次向终端设备传输待传输数据，可选的，网络设备可以在多个连续传输时间单元通过不同的波束向终端设备传输待传输数据。在该场景下，由于网络设备在多个连续传输时间单元通过不同的波束向终端设备传输待传输数据，因此，从时域的维度来看，终端设备每一次数据传输与HARQ进程序号的对应关系在时域上可以按照一定的HARQ进程序号顺序，具体的，终端设备每一次数据传输与HARQ进程序号的对应关系在多个连续传输时间单元可以按照一定的HARQ进程序号顺序。
在第二方面的一种可能设计中，数据传输方法还包括：该网络设备接收该终端设备发送的反馈确认应答ACK信息；该网络设备释放该多次传输的所有HARQ进程。当第四信息指示该待传输数据的多次传输的HARQ进程序号是循环递增的或者循环递减时，相当于网络设备多次传输中的每一次传输的HARQ进程序号是不同的，若终端设备的一次待传输数据接收成功，则会向网络设备反馈ACK信息，网络设备在接收到ACK信息后，会释放多次传输的所有HARQ进程序号对应的进程。需要说明的是，一个HARQ进程只会反馈一个ACK/NACK信息，多个HARQ进程则会反馈多个ACK/NACK信息，在多波束轮询的场景中，网络设备每一次数据传输采用的波束不同，若每一次数据传输都分配不同的HARQ进程，由于每一个HARQ进程可以得到一个ACK/NACK信息，则每一次数据传输都可以得到一个ACK/NACK信息，也就是每一个波束都可以得到一个对应的ACK/NACK信息，从而可以实现针对各个波束进行链路自适应，从而提高多波束传输的性能。

具体实施方式
本申请提供了一种数据传输方法，使得网络设备不需要每次数据传输都采用DCI来指示传输参数，节省了DCI资源，提高了小区数据传输的性能。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。

应当理解，尽管在本申请实施例中可能采用术语第一、第二、第三等来描述各种报文/帧、请求和终端，但这些报文/帧、请求和终端不应限于这些术语。这些术语仅用来将报文/帧、请求和终端彼此区分开。例如，在不脱离本申请实施例范围的情况下，第一终端也可以被称为第二终端，类似地，第二终端也可以被称为第一终端。
取决于语境，如在此所使用的词语“如果”或“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
应理解，本申请涉及名词“波束”，可以理解的是，一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等。例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。另外，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
应理解，本申请涉及名词“传输时间单元”，可以理解的是，传输时间单元在LTE系统中可以是传输时间间隔(transmission time interval，TTI)，LTE系统后续演进的通信系统(例如，新无线电(new radio，NR)系统)中还可以为时隙slot、时域符号、由一个或多 个时域符号组成的迷你时隙(mini slot)、由多个slot构成的时间单元、或者由多个mini-slot聚合组成的时间单元等。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(single-carrier frequency-division multiple access，SC-FDMA)符号。

下面介绍一下本申请应用的通信系统，参照图1A，图1A为本申请实施例中通信系统的一个实施例示意图。
如图1A所示，该通信系统包括网络设备和终端设备。
本申请实施例中，网络设备是一种部署在无线接入网中为终端设备提供无线通信功能的装置。网络设备可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB),在第三代(3rd Generation，3G)系统中，称为节点B(Node B)，在第五代(3rd Generation，5G)系统中成为无线网络接入设备等。为方便描述，本申请所有实施例中，上述为终端提供无线通信功能的装置统称为网络设备或基站或BS。

本申请实施例中，网络设备在指示终端设备多次传输中每次数据传输的传输参数之前，可以确定第一信息，其中，所述第一信息用于指示待传输数据的多次传输的传输参数，一方面，网络设备可以通过向终端设备发送第一信息来指示终端设备多次传输中每次数据传输的传输参数，进而终端设备可以通过网络设备指示的传输参数来接收终端设备每次发送的待传输数据，另一方面，网络设备可以根据该第一信息指示的传输参数多次向终端设备发送待传输数据。

303、终端设备获取所述第一信息。
本申请实施例中，终端设备可以通过接收网络设备发送的第一信息来获取所述第一信息，进而终端设备可以获取多次传输所需要的传输参数。本实施例和多次传输中每一次数据传输都需要携带传输参数的DCI的方案相比，本申请实施例中，网络设备通过向终端设备发送第一信息，该第一信息可以指示待传输数据多次传输的传输参数，使得网络设备不需要每次数据传输都采用DCI来指示传输参数。
在一种实施例中，第一信息可以包括传输配置编号TCI集合，其中TCI集合包括多个TCI，多次传输所采用的TCI属于TCI集合。本实施例中，每个TCI的编号可以指示一个波束信息，网络设备向终端设备发送第一信息，相当于指示终端设备多次传输对应的波束信息，终端设备在获取第一信息后就可以知道多次传输所需要的波束信息。本实施例中，每个TCI可以与待传输数据多次传输中的一次传输对应，其中每个TCI的编号可以指示一次传输对应的波束信息，终端设备根据第一信息获取到该TCI集合后，可以根据TCI编号与待传输数据每一次传输的对应关系，确定与每一次传输对应的波束信息，进而通过波束信息对应的波束来接收网络设备某次发送的待传输数据。
在一种实施例中，每个TCI编号可以指示一个参考信号天线端口，且每个参考信号天 线端口与待传输数据多次传输中的一次传输对应，该参考信号天线端口与一个波束信息具有准共址(quasi-co-location，QCL)关系。具体的，终端设备根据第一信息获取到TCI集合后，可以根据TCI编号与待传输数据每一次传输的对应关系，确定与每一次传输对应的参考信号天线端口，由于该参考信号天线端口与一个波束信息具有准共址(quasi-co-location，QCL)关系，进而终端设备可以确定与每一次传输对应的波束信息，并通过该波束信息对应的波束来接收网络设备某次发送的待传输数据。
应理解，本申请实施例中涉及的参考信号天线端口可以是同步信号广播信道块(SS-PBCH block)天线端口、信道状态信息参考信号(channel state information reference signal,CSI-RS)天线端口或探测参考信息(sounding reference signal，SRS)天线端口，或者其他参考信号天线端口，在此不做限定。
本实施例中，需要说明的是，如图1B所示，在另一种场景中，多个网络设备向一个终端设备调度传输控制信息，在该场景下，第一信息还可以包括传输待传输数据的网络设备的标识。也就是第一信息除了需要指示每一次传输所采用的波束之外，还需要指示每一次传输采用的波束是哪一个网络设备发送的。具体的，可以将TCI集合中的各个TCI与一个网络设备关联，需要说明的是，在该场景下，网络设备的数量可以小于多次传输中TCI的数量，在第一信息中，可以将网络设备标识与TCI集合中的至少一个TCI关联，即可以将一个网络设备与多个TCI关联。
本实施例中，可选的，第一信息还可以包括为该终端设备传输待传输数据的网络设备数量。
本实施例中，可选的，网络设备还可以向终端设备发送第二信息，第二信息用于指示目标TCI子集，目标TCI子集为TCI集合的一个子集。进一步的，目标TCI子集中的每个TCI与待传输数据多次传输中的一次传输对应。
本实施例中，网络设备可以通过向终端设备发送第二信息来指示终端设备采用TCI集合的一个TCI子集合作为多次传输的传输参数，该TCI子集合包括至少一个TCI，TCI子集合中的每个TCI编号与待传输数据多次传输中的一次传输对应，终端设备在接收到该TCI子集合后，可以根据TCI子集合的TCI编号与待传输数据每一次传输的对应关系，确定每一次传输对应的波束信息，进而通过波束信息对应的波束来接收网络设备某次发送的待传输数据。本实施例中，相当于第一信息指示了一个TCI集合，而在网络设备向终端设备多次发送待传输数据前，可以再发送一个第二信息到终端设备来指示TCI集合的一个TCI子集合作为多次传输的传输参数。示例性的，第一信息包括的TCI集合可以是{TCI1，TCI2，TCI3，TCI4，TCI5，TCI6，TCI7，TCI8，TCI9}，第二信息指示的目标TCI子集可以是{TCI1，TCI2，TCI3，TCI4}，则终端设备在接收到该第二信息后，可以确定目标TCI子集{TCI1，TCI2，TCI3，TCI4}中的每个TCI与待传输数据多次传输中的一次传输对应。本实施例中，通过向终端设备发送指示目标TCI子集的第二信息，使得网络设备可以根据实际需要指示终端设备采用TCI集合的一个TCI子集合作为多次传输的传输参数，增加了方案的灵活性。
本实施例中，可选的，网络设备可以通过媒体接入控制控制元素MAC CE或物理下行控制信道PDCCH向终端设备发送第二信息。
可选的，第一信息还可以指示待传输数据的多次传输的传输次数，示例性的，若第一信息指示待传输数据的多次传输的传输次数为6，则网络设备可以在6个连续传输时间单元发送待传输数据到终端设备。
以上介绍了网络设备通过向终端设备发送第一信息来指示待传输数据多次传输的传输参数，其中传输参数具体可以是TCI，接下来介绍网络设备如何指示待传输数据的每一次传输与TCI之间的关系。

在一种场景中，网络设备可以在不同的传输时间单元多次向终端设备传输待传输数据。第三信息可以指示在不同的传输时间单元按照第一顺序遍历TCI集合或目标TCI子集得到多次传输中每一次传输所采用的TCI。
在一种场景中，网络设备可以在不同的传输时间单元通过不同的天线端口采用不同的波束多次向终端设备传输待传输数据，第三信息可以指示在不同的传输时间单元和不同的天线端口按照第一顺序遍历TCI集合或目标TCI子集得到多次传输中每一次传输所采用的TCI。其中不同的传输时间单元可以是多个相邻或不相邻的传输时间单元。天线端口可以按照编号从小到大的顺序，或者从大到小的顺序，或者其他顺序。

应理解，以上示例中TCI集合中包括的TCI数量以及TCI的编号仅为一种示意，实际实施过程中可按照实际需求选择，这里并不限定。

如图4所示，本申请实施例提供的数据传输方法的另一个实施例包括：
401、网络设备确定第四信息，其中，第四信息用于指示待传输数据的多次传输的传输参数之间的关系。
本申请实施例中，网络设备确定第四信息，第四信息可以指示待传输数据的多次传输的传输参数之间的关系，网络设备可以根据第四信息指示的待传输数据的多次传输的传输参数之间的关系向终端设备发送待传输数据。
本实施例中，待传输数据的多次传输的传输参数之间的关系可以是多次传输的自动混合重传请求HARQ进程序号之间的关系，也可以是多次传输的时频资源之间的关系，以下分 别进行说明。
在一种实施例中，第四信息用于指示多次传输的自动混合重传请求HARQ进程序号相同。
本实施例中，一个HARQ进程序号对应一个HARQ进程，通常情况下，可以有8个HARQ进程序号，在5G系统中可以有16个HARQ序号，第四信息可以指示多次传输的自动混合重传请求HARQ进程序号相同，网络设备可以根据第四信息在待传输数据的多次传输中每一次传输采用的HARQ进程序号相同。
本实施例中，可选的，网络设备可以向终端设备发送一个目标HARQ进程序号，网络设备在待传输数据的多次传输中每一次传输可以都采用该目标HARQ进程序号，相应的，终端设备在待传输数据的多次传输中每一次传输可以都采用该目标HARQ进程序号。以HARQ进程序号的数量为8为例，HARQ进程序号可以包括{HARQ1，HARQ2，HARQ3，HARQ4，HARQ5，HARQ6，HARQ7，HARQ8}，若目标HARQ进程序号为HARQ4，则网络设备在待传输数据的多次传输中每一次传输可以都采用HARQ4对应的HARQ进程。
在一种实施例中，第四信息可以指示所述待传输数据的多次传输的HARQ进程序号是循环递增的或者循环递减的。
本实施例中，从时域的维度来看，网络设备每一次数据传输与HARQ进程序号的对应关系在时域上可以按照一定的HARQ进程序号顺序。第四信息可以指示所述待传输数据的多次传输的HARQ进程序号在时域上是循环递增的或者循环递减的。关于第四信息可以指示所述待传输数据的多次传输的HARQ进程序号是循环递增的或者循环递减的具体方式可以参照上述实施例中的描述，这里不再赘述。
在一种实施例中，第四信息可以指示各次传输的HARQ进程序号。例如，第四信息可以指示4次传输的HARQ进程序号为{HARQ1，HARQ4，HARQ5，HARQ7}。
本实施例中，可选的，网络设备可以接收终端设备发送的反馈确认应答ACK信息，网络设备在接收终端设备发送的ACK信息后，释放多次传输的所有HARQ进程。
本实施例中，当第四信息指示多次传输的自动混合重传请求HARQ进程序号相同时，相当于网络设备多次传输中的每一次传输的HARQ进程序号相同(例如传输的HARQ进程序号是HARQ1)，若终端设备的一次待传输数据接收成功，则会向网络设备反馈ACK信息，网络设备在接收到ACK信息后，释放HARQ1对应的HARQ进程。
本实施例中，当第四信息指示待传输数据的多次传输的HARQ进程序号是循环递增的或者循环递减时，相当于网络设备多次传输中的每一次传输的HARQ进程序号是不同的，若终端设备的一次待传输数据接收成功，则会向网络设备反馈ACK信息，网络设备在接收到ACK信息后，会释放多次传输的所有HARQ进程序号对应的进程。需要说明的是，一个HARQ进程只会反馈一个ACK/NACK信息，多个HARQ进程则会反馈多个ACK/NACK信息，在多波束轮询的场景中，网络设备每一次数据传输采用的波束不同，若每一次数据传输都分配不同的HARQ进程，由于每一个HARQ进程可以得到一个ACK/NACK信息，则每一次数据传输都可以得到一个ACK/NACK信息，也就是每一个波束都可以得到一个对应的ACK/NACK信息，从而可以实现针对各个波束进行链路自适应(波束级链路自适应)，从而提高多波束传输的性能。
在一种实施例中，第四信息用于指示多次传输的时频资源之间的关系。
在一种实施例中，第四信息用于指示如下信息中的至少一种：

需要说明的是，本实施例在不同的场景下，时域起始位置间隔的时间单位可以不同，例如可以是N个时隙slot、N个时域符号、N个迷你时隙(mini slot)或N个由多个slot、或者mini-slot聚合组成的时间单位等，其中N为正整数，这里并不限定。频域起始位置间隔的时间单位可以不同，例如可以是N个频域资源块(resource block,RB)、N个子载波或N个成员载波或N个预定义的带宽单位等，这里并不限定。
