Description

一种HARQ反馈方法及其装置 技术领域
本公开涉及通信技术领域,尤其涉及一种HARQ反馈方法及其装置。
背景技术
在无线通信技术的研究中,卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。但由于在卫星通信场景下信号传输距离较长,因此,导致了数据传输有较大的时延。这种较大的时延可能会导致混合自动重传请求(hybrid automatic repeat request,HARQ)延迟问题,即网络设备需要等待终端设备返回下行传输的HARQ反馈,才可以进行后续的下行传输,但由于这种较大的时延,网络设备等待时间较长,后续的下行传输受阻。
为了解决HARQ延迟问题,相关技术中,若网络设备通过调度指令调度了一个传输块,则终端设备可以基于该传输块的HARQ进程是否为未使能状态,从而确定是否需要发送HARQ反馈,相应地,对于网络设备来说,由于传输块的HARQ进程可以为未使能状态,能够至少避免网络设备等待未使能状态下的HARQ反馈。但相关技术中对于调度指令调度了多个传输块的情况,还缺少明确的HARQ反馈方式。
发明内容
本公开实施例提供一种HARQ反馈方法及其装置,可以应用于地面网络和非地面网络。其中非地面网络包括基于卫星通信的物联网(internet of things,IoT),例如窄带物联网(narrow band internet of things,NB-IoT);车联网,例如车与任何事物(vehicle to everything,V2X)通信、车间通信长期演进技术(long term evolution-vehicle,LTE-V)、车辆与车辆(vehicle to vehicle,V2V)通信等,或可以用于智能驾驶,智能网联车等领域。用于解决网络设备的调度指令在调度了多个传输块的情况下,如何进行HARQ反馈的问题。

其中,所述至少一个HARQ反馈中包括所述第一传输块对应的HARQ反馈。
在该技术方案中,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,向网络设备发送对应的HARQ反馈。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
在一种实现方式中,所述至少一个HARQ反馈中还包括:

具体实施方式
为了便于理解,首先介绍本公开涉及的术语。
1、下行控制信息(downlink control information,DCI)
DCI由物理下行控制信道(physical downlink control channel,PDCCH)承载,DCI可以包括上下行资源分配、HARQ反馈、功率控制等。PDCCH是一种物理信道,用于承载下行控制信息。
2、HARQ反馈
HARQ协议是蜂窝通信系统中的最重要的特征之一。HARQ反馈的反馈信息可以是HARQ确认(Acknowledge,ACK)反馈,或者,可以是HARQ否定(Negative Acknowledgement,NACK)反馈。利用HARQ协议,网络设备在发送新数据之前需要等待来自终端设备的反馈。在NACK的情况下,网络设备可能需要重新发送数据分组。否则,该网络设备可发送新的数据。这种停止和等待过程给通信协议引入了固有的时延,这可能会降低链路吞吐量。
为了解决HARQ延迟问题,相关技术中,若网络设备通过调度指令调度了一个传输块,则终端设备可以基于该传输块的HARQ进程是否为未使能状态,从而确定是否需要发送HARQ反馈,相应地,对于网络设备来说,由于传输块的HARQ进程可以为未使能状态,能够至少避免网络设备等待未使能状态下的HARQ反馈。但相关技术中对于调度指令调度了多个传输块的情况,还缺少明确的HARQ反馈方式。
为了更好的理解本公开实施例公开的一种HARQ反馈方法,下面首先对本公开实施例适用的通信系统进行描述。

为了清楚说明在前述通信系统中,基于网络设备的调度指令调度了多个传输块的情况下,终端设备的HARQ反馈的方式,下面结合附图对本公开所提供的HARQ反馈方法及其装置进行详细地介绍。
请参见图2,图2是本公开实施例提供的一种HARQ反馈方法的流程示意图。如图2所示,该方法由终端设备执行,该方法可以包括但不限于如下步骤:
步骤201,接收网络设备发送的调度指令,调度指令用于调度多个传输块的传输。
在本公开的所有实施例中,是通过同一个调度指令来调度多个传输块。
网络设备通过在调度指令调度多个传输块的传输,以便终端设备在调度指令所调度的多个传输资源上对应接收多个传输块所承载的信息,进而在终端设备接收到多个传输块所承载的信息之后,该终端设备可以针对这多个传输块确定是否需要进行HARQ反馈,和/或确定HARQ反馈的HARQ信息。在本公开实施例中,多个是指两个或两个以上。
例如:对于NB-IoT的终端设备,网络设备可以通过窄带物理下行控制信道(Narrowband Physical Downlink Control Channel,NPDCCH)调度多(multiple)窄带物理下行共享信道(Narrowband Physical Downlink Shared Channel,NPDSCH)信道的单播传输块。在网络设备对两个NPDSCH信道的单播传输块进行调度的示例中,可以将调度的传输块记为TB(Transport Block)1和TB2。在终端设备在调度指令所调度的传输块TB1和TB2的传输资源上对应接收传输块TB1和TB2所承载的信息,进而在终端设备接收到传输块TB1和TB2所承载的信息之后,针对TB1和TB2分别确定是否发送对应的HARQ反馈。具体进行HARQ反馈的步骤将在后续步骤中进行描述,本步骤中对此不再赘述。
需要说明的是,网络设备可以基于DCI信令发送该调度指令,或者基于无线资源控制(Radio Resource Control,RRC)等高层信令发送该调度指令或者基于移动边缘计算(Mobile Edge Computing,MEC)用户网络边缘设备(Customer Edge,CE)等物理层信令发送该调 度指令,本实施例中对此不作限定。
步骤202,响应于多个传输块中包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,向网络设备发送至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈。
网络设备通过第一传输块和第二传输块进行信息传输。在终端设备接收到网络设备通过第一传输块和第二传输块承载的信息之后,分别对接收到的第一传输块承载的信息和第二传输块承载的信息进行解码,以确定是否对第一传输块承载的信息和第二传输块承载的信息进行了正确的接收。
针对第一传输块,若终端设备正确接收了第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为ACK;若终端设备未正确接收第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为NACK。相应地,网络设备根据终端设备发送的第一传输块对应HARQ反馈的HARQ信息为ACK或NACK,确定终端设备是否已对第一传输块承载的信息承载的信息进行了正确的接收。
针对第二传输块,由于是未使能HARQ反馈的第二传输块,因此无论终端设备是否正确接收了第二传输块承载的信息,均不需向网络设备发送第二传输块对应的HARQ反馈。即,步骤202中,响应于多个传输块包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,向网络设备发送至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈,且不包括第二传输块对应的HARQ反馈。
如图3所示,示意图描述了在同一调度指令调度了两个传输块的情况下,终端设备基于下行信道(Downlink channel,DL)接收到TB1传输和TB2传输。其中,TB1传输所采用的传输块TB1为使能HARQ反馈的第一传输块,TB2传输所采用的传输块TB2为未使能HARQ反馈的第二传输块。如图3所示,终端设备可以在上行信道(Uplink channel,UL)中传输针对传输块TB1的HARQ反馈,而不传输针对传输块TB2的HARQ反馈。从而相应地,网络设备在基于下行信道传输TB1传输和TB2传输之后,仅需要等待接收终端设备针对传输块TB1的HARQ反馈,而不需要等待针对传输块TB2的HARQ反馈,便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
通过实施本公开实施例,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,向网络设备发送对应的HARQ反馈。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
请参见图4,图4是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图4所示,该方法由终端设备执行,该方法可以包括但不限于如下步骤:
步骤401,接收网络设备发送的调度指令,调度指令用于调度多个传输块的传输。
参见前述实施例中的相关描述,本实施例中不再赘述。
步骤402,响应于多个传输块中包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,向网络设备发送至少一个HARQ反馈,其中,至少一个HARQ反馈中包 括第一传输块对应的HARQ反馈和第二传输块对应的HARQ反馈。
网络设备通过第一传输块和第二传输块进行信息传输。在终端设备接收到网络设备通过第一传输块和第二传输块承载的信息之后,终端设备分别对第一传输块承载的信息和第二传输块承载的信息进行解码,以确定是否对第一传输块承载的信息和第二传输块承载的信息进行了正确的接收。
针对第一传输块,若终端设备正确接收了第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为ACK;若终端设备未正确接收第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为NACK。相应地,网络设备根据终端设备发送的第一传输块对应HARQ反馈的HARQ信息为ACK或NACK,确定终端设备是否已对第一传输块承载的信息承载的信息进行了正确的接收。
针对第二传输块,作为第一种可能的实现方式,第二传输块对应的HARQ反馈所包含的HARQ信息是用于确定第二传输块承载的信息是否接收成功的HARQ信息。若终端设备正确接收了第二传输块承载的信息,则第二传输块对应的HARQ反馈包含的HARQ信息为ACK;若终端设备未正确接收第二传输块承载的信息,则第二传输块对应的HARQ反馈包含的HARQ信息为NACK。相应地,网络设备根据终端设备发送的第二传输块对应HARQ反馈的HARQ信息为ACK或NACK,确定终端设备是否已对第二传输块承载的信息承载的信息进行了正确的接收。网络设备可以等待针对第二传输块的HARQ反馈,也可以无需等待针对第二传输块的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
针对第二传输块,作为第二种可能的实现方式,第二传输块对应的HARQ反馈中的HARQ信息是默认值。也就是说无论终端设备是否正确接收了第二传输块承载的信息,第二传输块对应的HARQ反馈包含的HARQ信息都是同样的默认值,这个默认值示例性的可以是ACK,也可以是NACK。相应地,网络设备无法根据终端设备发送的第二传输块对应HARQ反馈的HARQ信息,确定终端设备是否已对第二传输块承载的信息承载的信息进行了正确的接收,因此,网络设备可以无需等待针对第二传输块的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
如图5所示,示意图描述了在同一调度指令调度了两个传输块的情况下,终端设备基于下行信道(DL)接收到TB1传输和TB2传输。其中,TB1传输所采用的传输块TB1为使能HARQ反馈的第一传输块,TB2传输所采用的传输块TB2为未使能HARQ反馈的第二传输块。如图5所示,终端设备可以在上行信道(UL)中传输针对传输块TB1的HARQ反馈,以及传输针对传输块TB2的HARQ反馈。从而相应地,网络设备在基于下行信道传输TB1传输和TB2传输之后,需要等待接收终端设备针对传输块TB1的HARQ反馈。在接收到针对传输块TB1的HARQ反馈之后,网络设备可以等待针对传输块TB2的HARQ反馈,也可以无需等待针对传输块TB2的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
通过实施本公开实施例,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,可以针对多个传输块中使能HARQ反馈的第一传输块,向网络设备发送对应的HARQ反馈。网络设备可以等待针对第二传输块的HARQ反馈,也可以无需等待针对第 二传输块的HARQ反馈便可以进行后续传输。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
请参见图6,图6是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图6所示,该方法由终端设备执行,该方法可以包括但不限于如下步骤:
步骤601,接收网络设备发送的调度指令,调度指令用于调度多个传输块的传输。
参见前述实施例中的相关描述,本实施例中不再赘述。
步骤602,响应于多个传输块中仅包括未使能HARQ反馈的第二传输块,则不向网络设备发送任一第二传输块对应的HARQ反馈。
网络设备通过第二传输块进行信息传输。在终端设备接收到网络设备通过第二传输块承载的信息之后,终端设备分别对各第二传输块承载的信息进行解码,以确定是否对各第二传输块承载的信息进行了正确的接收。针对各第二传输块,无论终端设备是否正确接收了各第二传输块承载的信息,终端设备均不向网络设备发送任一第二传输块对应的HARQ反馈。因此,网络设备可以无需等待针对第二传输块的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
如图7所示,示意图描述了在同一调度指令调度了两个传输块的情况下,终端设备基于下行信道(DL)接收到TB1传输和TB2传输。其中,TB1传输所采用的传输块TB1,以及TB2传输所采用的传输块TB2均为未使能HARQ反馈的第二传输块。如图7所示,终端设备可以在上行信道(UL)中不发送任一HARQ反馈,即不发送针对传输块TB1的HARQ反馈,且不发送针对传输块TB2的HARQ反馈。从而相应地,网络设备在基于下行信道进行传输块TB1的传输和传输块TB2的传输之后,无需等待接收终端设备针对传输块TB1和TB2的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
通过实施本公开实施例,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,在多个传输块中若仅包括未使能HARQ反馈的第二传输块,则不向网络设备发送任一第二传输块对应的HARQ反馈。相应地,网络设备可以无需等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
请参见图8,图8是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图8所示,该方法由终端设备执行,该方法可以包括但不限于如下步骤:
步骤801,接收网络设备发送的调度指令,调度指令用于调度多个传输块的传输。
参见前述实施例中的相关描述,本实施例中不再赘述。
步骤802,响应于多个传输块中仅包括使能HARQ反馈的第一传输块,向网络设备发送至少一个第一传输块对应的HARQ反馈。
网络设备通过第一传输块进行信息传输。在终端设备接收到网络设备通过第一传输块 承载的信息之后,终端设备分别对各第一传输块承载的信息进行解码,以确定是否对各第一传输块承载的信息进行了正确的接收。
针对各第一传输块,终端设备可以仅向网络设备发送多个第一传输块中一个第一传输块对应的HARQ反馈,或者,还可以针对每个第一传输块向网络设备发送对应的HARQ反馈。
作为一种可能的实现方式,终端设备仅向网络设备发送多个第一传输块中一个第一传输块对应的HARQ反馈,终端设备发送的HARQ反馈的HARQ信息可以是基于多个第一传输块承载的信息是否进行了正确的接收确定的,例如:在多个第一传输块承载的信息均进行了正确的接收的情况下,终端设备向网络发送的HARQ反馈的HARQ反馈信息可以是ACK;在多个第一传输块承载的信息中存在至少一个传输块承载的信息未被正确接收的情况下,终端设备向网络发送的HARQ反馈的HARQ反馈信息可以是NACK。
作为另一种可能的实现方式,终端设备向网络设备发送多个第一传输块中每个第一传输块发送对应的HARQ反馈,终端设备发送的HARQ反馈的HARQ信息可以是基于对应第一传输块承载的信息是否进行了正确的接收确定的。
如图9所示,示意图描述了在同一调度指令调度了两个传输块的情况下,终端设备基于下行信道(DL)接收到TB1传输和TB2传输。其中,TB1传输所采用的传输块TB1,以及TB2传输所采用的传输块TB2均为使能HARQ反馈的第一传输块。终端设备可以在上行信道(UL)中发送针对至少一个传输块的HARQ反馈,例如:如图9所示,可以针对传输块TB1和传输块TB2均发送HARQ反馈。相应地,网络设备在基于下行信道进行传输块TB1的传输和传输块TB2的传输之后,可以等待接收针对传输块TB1和TB2中至少一个传输块的HARQ反馈,而无需等待接收终端设备针对传输块TB1和TB2中其余传输块的HARQ反馈,便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
需要说明的是,本领域技术人员可以理解,网络设备也可以等待接收到针对传输块TB1和TB2中全部传输块的HARQ反馈之后,再进行后续传输,本实施例中对此不作限制。
通过实施本公开实施例,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,在多个传输块中若仅包括使能HARQ反馈的第一传输块,则向网络设备发送至少一个第一传输块对应的HARQ反馈。相应地,网络设备在接收到多个传输块中至少一个传输块对应的HARQ反馈之后,便可以进行后续的传输。通过这种方式,可以避免网络设备必须等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
请参见图10,图10是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图10所示,该方法由终端设备执行,该方法可以包括但不限于如下步骤:
步骤1001,接收网络设备发送的指示信息,其中,指示信息,用于确定多个传输块中至少一个传输块是否为使能HARQ反馈的第一传输块,或者为未使能HARQ反馈的第二传输块。
在本公开的实施例中,在一种可能的实现方式中,可以指示每一个传输块是使能HARQ反馈还是未使能HARQ反馈。在另一种可能的实现方式中,可以默认传输块是使能HARQ 反馈,且网络设备指示未使能HARQ反馈的传输块。在又一种可能的实现方式中,可以默认传输块是未使能HARQ反馈,且网络设备指示使能HARQ反馈的传输块。网络设备基于RRC等高层信令发送该指示信息或者基于MEC CE等物理层信令发送该指示信息,又或者网络设备基于DCI信令发送该指示信息,本实施例中对此不作限定。
作为一种可能的实现方式,该指示信息用于指示网络设备和终端设备之间可用的多个传输块。用于发送该指示信息的信令中还携带指示域,该指示域可以是新增的,也可以是复用已有指示域。终端设备根据该指示域确定多个传输块中至少一个传输块是否为使能HARQ反馈的第一传输块,或者为未使能HARQ反馈的第二传输块。
网络设备通过指示信息使得终端设备确定网络设备和终端设备之间可用的多个传输块,且多个传输块是否为第一传输块或者第二传输块,以便网络设备通过调度指令,从可用的多个传输块中选取至少部分传输块进行调度。
本领域技术人员可以知晓,用于指示多个传输块是否为第一传输块或第二传输块的指示信息可以是通过多条信令发送的,例如:每条信令指示了至少一个传输块是否为第一传输块或者第二传输块;指示信息还可以是通过一条信令发送的,例如:通过一条信令发送了该指示信息,指示了多个传输块分别是否为第一传输块或者第二传输块。
步骤1002,接收网络设备发送的调度指令,调度指令用于调度多个传输块的传输。
步骤1003,响应于多个传输块中包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,向网络设备发送至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈。
步骤1002和步骤1003具体参见前述实施例中的相关描述,本实施例中对此不再赘述。
通过实施本公开实施例,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,向网络设备发送对应的HARQ反馈。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
请参见图11,图11是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图10所示,该方法由终端设备执行,该方法可以包括但不限于如下步骤:
步骤1101,基于协议约定的配置信息,确定多个传输块中至少一个传输块为第一传输块,或者为第二传输块。
作为一种可能的实现方式,协议约定的配置信息中,约定了用于网络设备和终端设备之间可用的多个传输块,且多个传输块是否为第一传输块或者第二传输块。以便网络设备通过调度指令,从约定的可用的多个传输块中选取至少部分传输块进行调度。
步骤1102,接收网络设备发送的调度指令,调度指令用于调度多个传输块的传输。
步骤1103,响应于多个传输块中包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,向网络设备发送至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈。
步骤1102和步骤1103具体参见前述实施例中的相关描述,本实施例中对此不再赘述。
通过实施本公开实施例,终端设备在接收到同一调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,向网络设备发送对应的HARQ反馈。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
本领域内技术人员可以理解,前述的多个由终端设备执行的实施例既可以独立被实施,也可以以任何方式结合在一起被实施,本公开实施例并不对此做出限定。
请参见图12,图12是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图12所示,该方法由网络设备执行,该方法可以包括但不限于如下步骤:
步骤1201,向终端设备发送调度指令,调度指令用于调度了多个传输块。
网络设备可以向终端设备发送调度指令。其中,调度指令用于调度多个传输块的传输。可以理解的是,由于网络设备可以在调度指令中调度多个传输块的传输,从而终端设备可以在调度指令所调度的多个传输资源上对应接收多个传输块所承载的信息,进而在终端设备接收到多个传输块所承载的信息之后,该终端设备可以针对这多个传输块确定是否需要进行HARQ反馈,和/或确定HARQ反馈的HARQ信息。
需要说明的是,网络设备可以基于DCI信令发送该调度指令,或者基于RRC等高层信令发送该调度指令或者基于MEC CE等物理层信令发送该调度指令,本实施例中对此不作限定。
步骤1202,响应于多个传输块中包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,则等待接收终端设备发送的至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈。
网络设备通过第一传输块和第二传输块进行信息传输。终端设备在接收到网络设备通过第一传输块和第二传输块承载的信息之后,会分别对接收到的第一传输块承载的信息和第二传输块承载的信息进行解码,以确定是否对第一传输块承载的信息和第二传输块承载的信息进行了正确的接收,并向网络设备发送HARQ反馈,以使网络设备能够在接收到终端设备发送的HARQ反馈之后,继续进行后续的传输。
针对第一传输块,终端设备可以基于是否对第一传输块承载的信息和第二传输块承载的信息进行了正确的接收,向网络设备发送第一传输块对应HARQ反馈的HARQ信息。具体地,若终端设备正确接收了第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为ACK;若终端设备未正确接收第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为NACK。相应地,网络设备可以等待接收终端设备发送的第一传输块对应HARQ反馈的HARQ信息,并根据该HARQ信息为ACK或NACK,确定终端设备是否已对第一传输块承载的信息承载的信息进行了正确的接收。
针对第二传输块,由于是未使能HARQ反馈的第二传输块,因此无论终端设备是否正确接收了第二传输块承载的信息,终端设备均不需向网络设备发送第二传输块对应的HARQ反馈。相应地,网络设备也无需等待接收终端设备发送的第二传输块对应的HARQ反馈。即,步骤1202中,响应于多个传输块包括使能HARQ反馈的第一传输块和未使能 HARQ反馈的第二传输块,则等待接收终端设备发送的至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈,且不包括第二传输块对应的HARQ反馈。
通过实施本公开实施例,网络设备在向终端设备发送调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,等待接收终端设备发送的对应的HARQ反馈。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。

网络设备通过第一传输块和第二传输块进行信息传输。终端设备在接收到网络设备通过第一传输块和第二传输块承载的信息之后,会分别对接收到的第一传输块承载的信息和第二传输块承载的信息进行解码,以确定是否对第一传输块承载的信息和第二传输块承载的信息进行了正确的接收,并向网络设备发送HARQ反馈,以使网络设备能够在接收到终端设备发送的HARQ反馈之后,继续进行后续的传输。
针对第一传输块,终端设备可以基于是否对第一传输块承载的信息和第二传输块承载的信息进行了正确的接收,向网络设备发送第一传输块对应HARQ反馈的HARQ信息。具体地,若终端设备正确接收了第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为ACK;若终端设备未正确接收第一传输块承载的信息,则第一传输块对应的HARQ反馈的HARQ信息为NACK。相应地,网络设备可以等待接收终端设备发送的第一传输块对应HARQ反馈的HARQ信息,并根据该HARQ信息为ACK或NACK,确定终端设备是否已对第一传输块承载的信息承载的信息进行了正确的接收。
针对第二传输块,作为第一种可能的实现方式,第二传输块对应的HARQ反馈所包含的HARQ信息是用于确定第二传输块承载的信息是否接收成功的HARQ信息。若终端设备正确接收了第二传输块承载的信息,则第二传输块对应的HARQ反馈包含的HARQ信息为ACK;若终端设备未正确接收第二传输块承载的信息,则第二传输块对应的HARQ反馈包含的HARQ信息为NACK。相应地,网络设备根据终端设备发送的第二传输块对应HARQ反馈的HARQ信息为ACK或NACK,确定终端设备是否已对第二传输块承载的信息承载的信息进行了正确的接收。需要说明的是,网络设备可以等待针对第二传输块的HARQ反馈,也可以无需等待针对第二传输块的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
针对第二传输块,作为第二种可能的实现方式,第二传输块对应的HARQ反馈中的 HARQ信息是默认值。也就是说无论终端设备是否正确接收了第二传输块承载的信息,第二传输块对应的HARQ反馈包含的HARQ信息都是同样的默认值,这个默认值示例性的可以是ACK,也可以是NACK。相应地,网络设备无法根据终端设备发送的第二传输块对应HARQ反馈的HARQ信息,确定终端设备是否已对第二传输块承载的信息承载的信息进行了正确的接收,因此,网络设备可以无需等待针对第二传输块的HARQ反馈便可以进行后续传输,从而在一定程度上减少了等待导致的传输时延。
通过实施本公开实施例,网络设备向终端设备发送调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,等待接收终端设备发送的对应的HARQ反馈。网络设备可以等待针对第二传输块的HARQ反馈,也可以无需等待针对第二传输块的HARQ反馈便可以进行后续传输。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。

针对各第一传输块,终端设备可以仅向网络设备发送多个第一传输块中一个第一传输块对应的HARQ反馈,或者,还可以针对每个第一传输块向网络设备发送对应的HARQ反馈。
作为一种可能的实现方式,终端设备仅向网络设备发送多个第一传输块中一个第一传输块对应的HARQ反馈,从而网络设备可以等待接收终端设备发送的这一个第一传输块对应的HARQ反馈。可选地,终端设备发送的HARQ反馈的HARQ信息可以是基于多个第一传输块承载的信息是否进行了正确的接收确定的,例如:在多个第一传输块承载的信息均进行了正确的接收的情况下,终端设备向网络发送的HARQ反馈的HARQ反馈信息可以是ACK;在多个第一传输块承载的信息中存在至少一个传输块承载的信息未被正确接收的情况下,终端设备向网络发送的HARQ反馈的HARQ反馈信息可以是NACK。
作为另一种可能的实现方式,终端设备向网络设备发送多个第一传输块中每个第一传输块发送对应的HARQ反馈,从而网络设备可以等待接收终端设备发送的每个第一传输块对应的HARQ反馈。可选地,终端设备发送的HARQ反馈的HARQ信息可以是基于对应第一传输块承载的信息是否进行了正确的接收确定的。
通过实施本公开实施例,网络设备在向终端设备发送调度指令所调度的多个传输块所承载的信息之后,在多个传输块中若仅包括使能HARQ反馈的第一传输块,则等待接收终端设备发送的至少一个第一传输块对应的HARQ反馈。也就是说,网络设备在接收到多个传输块中至少一个传输块对应的HARQ反馈之后,便可以进行后续的传输。通过这种方式,可以避免网络设备必须等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
请参见图16,图16是本公开实施例提供的另一种HARQ反馈方法的流程示意图。如图16所示,该方法由网络设备执行,该方法可以包括但不限于如下步骤:
步骤1601,向终端设备发送指示信息,其中,指示信息,用于确定多个传输块中至少一个传输块是否为第一传输块,或者为第二传输块。
在本公开的实施例中,在一种可能的实现方式中,可以指示每一个传输块是使能HARQ反馈还是未使能HARQ反馈。网络设备基于RRC等高层信令发送该指示信息或者基于MEC CE等物理层信令发送该指示信息,又或者网络设备基于DCI信令发送该指示信息,本实施例中对此不作限定。
作为一种可能的实现方式,该指示信息用于指示网络设备和终端设备之间可用的多个传输块。用于发送该指示信息的信令中还携带指示域,该指示域可以是新增的,也可以是复用已有指示域。终端设备根据该指示域确定多个传输块中至少一个传输块是否为使能HARQ反馈的第一传输块,或者为未使能HARQ反馈的第二传输块。
网络设备通过指示信息使得终端设备确定网络设备和终端设备之间可用的多个传输块,且多个传输块是否为第一传输块或者第二传输块,以便网络设备通过调度指令,从可用的多个传输块中选取至少部分传输块进行调度。
本领域技术人员可以知晓,用于指示多个传输块是否为第一传输块或第二传输块的指示信息可以是通过多条信令发送的,例如:每条信令指示了至少一个传输块是否为第一传输块或者第二传输块;指示信息还可以是通过一条信令发送的,例如:通过一条信令发送了该指示信息,指示了多个传输块分别是否为第一传输块或者第二传输块。
步骤1602,向终端设备发送调度指令,调度指令用于调度了多个传输块。
步骤1603,响应于多个传输块中包括使能HARQ反馈的第一传输块和未使能HARQ反馈的第二传输块,则等待接收终端设备发送的至少一个HARQ反馈,其中,至少一个HARQ反馈中包括第一传输块对应的HARQ反馈。
步骤1602和步骤1603具体参见前述实施例中的相关描述,本实施例中对此不再赘述。
通过实施本公开实施例,网络设备在向终端设备发送调度指令所调度的多个传输块所承载的信息之后,可以仅针对多个传输块中使能HARQ反馈的第一传输块,等待接收终端设备发送的对应的HARQ反馈。通过这种方式,可以避免网络设备等待多个传输块中所有传输块对应的HARQ反馈均接收到之后,再进行后续的传输,从而有利于在一定程度上减少由于等待HARQ反馈所导致的传输时延。
本领域内技术人员可以理解,前述的多个由网络设备执行的实施例既可以独立被实施,也可以以任何方式结合在一起被实施,本公开实施例并不对此做出限定。
