Description

获取、传输HARQ反馈信息的方法及装置 技术领域
本公开涉及通信技术领域,尤其涉及一种获取、传输HARQ反馈信息的方法及装置。
背景技术
随着无线通信技术的发展,移动通信网络逐渐向5G网络演进。5G网络在数据传输速率、覆盖、时延、容量等方面的能力有很大提升,可以根据用户需求配置更多下行业务类型,比如eMBB(enhanced Mobile Broad Band,增强移动宽带)、mMTC(massive Machine Type Communication,海量机器类通信)、URLLC(Ultra Reliable Low Latency Communication,超高可靠低时延通信)等多种类型,应用于宽带连接、物联网、车联网、广域覆盖等。
在两个设备之间如基站向用户设备传输非敏感业务数据如mMTC业务时,由于mMTC业务对时延不敏感,可以采用预设数量的长TTI(Transmission Time Interval,时间间隔)进行数据传输。其中,上述长TTI是上述非敏感业务传输的基本单位,具有更长的时间周期比如10ms。在此过程中,应业务需求,如果有需要采用短TTI传输的时延敏感业务需要在两个设备间传输,则上述长TTI中也应该允许调度上述短TTI。
根据相关技术,由于长TTI对应的HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈资源已配置完成,一般在上述长TTI的尾部,如图1-1所示。当在长TTI中调度短TTI后,只能利用上述长TTI的HARQ反馈资源103发送上述短TTI200的HARQ反馈信息,如图1-2所示。由于长TTI的时间周期大于上述短TTI的时间周期,根据长TTI的传输特性,势必增加短TTI的HARQ反馈时延,增加时延敏感数据的传输时间,同时还会导致长TTI的资源浪费。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
首先,本公开中涉及的第一设备、第二设备可以是基站、子基站、用户设备等。其中,用户设备UE可以是用户终端、用户节点、移动终端或平板电脑等具有移动通信功能的设备,上述设备适用于5G蜂窝通信***。
对本公开的HARQ机制进行说明,在HARQ传输机制中,第一设备采用预设长度的时间间隔TTI向第二设备发送下行业务数据后,暂停下来等待接收第二设备发送的HARQ反馈信息。第二设备对每一个接收到的业务数据包进行检错,若接收正确生成确认信号ACK;若接收错误则生成不确认信号NACK;将上述HARQ反馈信息通过指定的HARQ反馈资源返回第一设备。若第一设备收到ACK信号,接着向第二设备发送新的下行业务数据包;若第一设备收到NACK信号,则向第二设备重新发送上次发送过的业务数据包。
本公开的一示例性应用场景为:第一设备在采用长TTI向第二设备传输非时延敏感业务数据如mMTC业务数据的过程中,接收到第二设备发送的用于获取时延敏感业务如URLLC业务的业务请求,第一设备需要中断mMTC业务数据的传输,在至少一个上述长TTI中调度至少一个短TTI,及时将所述短TTI承载的URLLC业务数据发送给第二设备,并确保第一设备可以快速获取上述短TTI的HARQ反馈信息。其中,上述长TTI的长度大于所述短TTI的长度,TTI的长度也可称为时间周期,例如,上述长TTI的长度为10ms,上述短TTI的长度可以为1ms、2ms、4ms等。
基于此,本公开提供了一种获取HARQ反馈信息的方法,应用于第一设备中。参照图2根据一示例性实施例示出的一种获取HARQ反馈信息的方法流程图,所述方法可以包括:
在步骤11中,根据用户需求在第一目标长TTI中设置短TTI的调度信息,其中,所述调度信息至少包括:短TTI的位置信息、长度信息、数量信息、HARQ反馈资源的位置信息,其中,所述HARQ反馈资源被第二设备用作向所述第一设备发送所述短TTI的HARQ反馈信息;
本公开中,第一设备在第一目标长TTI中设置短TTI的调度信息。第一设备可通过该调度信息知道如何在预设的长TTI中调度短TTI,第二设备在获取到上述短TTI的调度信息之后,可知道如何接收并处理短TTI。
根据上述应用场景并结合图1-1,当第一设备准备调度第22号长TTI 传输mMTC业务数据时,接收到第二设备获取URLLC业务数据的业务请求信息。此时,第一设备会临时中断mMTC业务数据的传输,在第22号长TTI中设置短TTI的调度信息。上述第22号长TTI即为本公开中的第一目标长TTI。也就是说第一目标长TTI中设置有短TTI的调度信息,通过该第一目标长TTI,第一设备可以将短TTI的调度信息发送给第二设备。
本公开中,第一设备设置的短TTI的调度信息至少包括:短TTI的位置信息、长度信息、数量信息、HARQ反馈资源的位置信息。
其中,短TTI的位置信息用于指定在哪个长TTI中调度短TTI,可以是长TTI的编号,如第23号;或者,长TTI的位置偏移值,即调度了短TTI的长TTI相对于当前长TTI的位置偏移值。如上,当前在第22号长TTI中设置有短TTI的调度信息,如果指定在第23号长TTI中调度短TTI,则上述位置偏移值为1。以上描述了在后序长TTI中延迟调度短TTI的情况,本公开实施例中,也可以通过所述短TTI的位置信息指定在当前长TTI中调度短TTI,对于此种情况,上述TTI的位置信息可以表示为:第22号,或位置偏移值0。
短TTI的长度信息表示待调度的短TTI的长度。在本公开一实施例中,可以在长TTI中调度相同长度的短TTI,例如,1ms,当短TTI的长度等于上述长TTI长度的整数分之一时,示例性的,上述长度信息可以表示为:10ms/N,其中,整数N为大1的自然数。本公开另一实施例中,也可以在长TTI中调度不同长度的短TTI,例如,根据不同长度将待调度的短TTI分为三类,可以采用短TTI分类列表记录短TTI的类别与长度的对应关系,如表一所示:
短TTI的类别 长度
第一类 1ms
第二类 2ms
第三类 4ms
表一
短TTI的数量信息表示在长TTI中调度的短TTI的数量。当待调度的短TTI的长度相同时,则上述数量信息可以为一个整数N,比如2。示例性的,若上述长度信息可以表示为:10ms/2n时,则上述数量信息可以表示为:2n,或仅用2的指数n表示,n为大于等于1的自然数。从而尽可能减少调度信息的数据量,减少信令开销。
当待调度的短TTI的长度不同时,可以采用短TTI数量列表记录短TTI的种类和/或长度与数量的对应关系。示例性的,当上述短TTI数量列表记录了短TTI的种类与数量的对应关系时,上述短TTI数量列表可以如表二所示:
短TTI的类别 数量
第一类 1
第二类 1
第三类 1
表二
在进行数量设置时,还需考虑每个短TTI的长度信息,使得所有待调度的短TTI的长度之和不超过一个长TTI的长度。如表二所示,所有待调度短TTI的长度之和为:1ms×1+2ms×1+4ms×1=7ms,小于一个长TTI的长度10ms。
短TTI的HARQ反馈资源的位置信息,用于表示在短TTI的什么位置配置HARQ反馈资源。
本公开实施例中,每个短TTI都设置有对应的HARQ反馈资源。本公开中,可以至少采用以下两种方式设置短TTI的HARQ反馈资源:
第一种方式,在每个短TTI的尾部紧邻设置所述HARQ反馈资源;
参照图3-1所示的一种调度短TTI后的目标长TTI的结构示意图,在一实施例中,短TTI200对应的HARQ反馈资源203可以设置于短TTI200 的尾部。即每一个短TTI200的尾部都紧邻设置有一个HARQ反馈资源203。
本公开实施例中,当一个长TTI在调度一个或多个短TTI后还有冗余资源时(对应图中的空白处),一种情况是不再利用上述冗余资源,以提高短TTI的传输效率。另一种情况下,可以利用上述冗余资源继续调度非时延敏感数据,避免资源浪费。假设一个10ms的长TTI在调度了一个1ms的短TTI之后,还剩余9ms的资源,原始计划分配给该长TTI的数据为1-10,则可利用上述冗余资源传输数据1-9。
第二种方式,当一个长TTI在调度一个或多个短TTI后还有冗余资源时,指定最后一个短TTI使用所述长TTI原始配置的HARQ反馈资源。
参照图3-2所示的另一种调度短TTI后的目标长TTI的结构示意图,在一个长TTI调度了3个短TTI200之后,还剩余较少的冗余资源(对应图中的空白处),则可以将所述长TTI原始配置的HARQ反馈资源103指定为第三个短TTI的HARQ反馈资源。从而保留原有配置的HARQ反馈资源的有效性,减少一个长TTI中HARQ反馈资源的配置数量,降低***的复杂性。
参照图4根据一示例性实施例示出的另一种获取HARQ反馈信息的方法流程图,上述步骤11可以包括:
在步骤111中,在使用长TTI传输数据时,监听低时延业务请求;
仍如图1-1所示场景,第一设备原本配置了50个长TTI,用于向第二设备传输mMTC业务数据。在第一设备采用长TTI发送mMTC业务数据时,同时监听第二设备发送的业务请求,根据监听到的业务请求判断该请求是否属于低时延业务请求,若是,执行下述步骤112,若否,可以不处理或延迟处理,比如等上述50个长TTI传输完毕后再处理。
在步骤112中,当监听到所述低时延业务请求时,在第一目标长TTI中设置短TTI的调度信息,其中,所述短TTI用于传输低时延业务数据。
如图1-1,当第一设备在发送了前21个长TTI,即将发送第22号长TTI时,监听到了低时延业务请求,如URLLC业务请求,则中断传输mMTC 业务数据,优先在第22号长TTI中设置短TTI的调度信息。
本公开实施例中,关于在长TTI的什么位置设置短TTI的调度信息,可以包括以下两种情况:
第一种情况,在第一目标长TTI的控制信令中设置短TTI的调度信息;
如图1-1中示出的一个长TTI的结构示意图,可以在位于第22号长TTI头部的控制信令101中设置短TTI的调度信息。适用于通过PDCCH(Physical Downlink Control Channel,物理下行控制信道)承载控制信令的传输中。
本公开实施例中,根据调度信息对应短TTI的数量不同,可以进一步包括两种设置调度信息的方式:
第一种设置方式:将一个长TTI的所有待调度短TTI的调度信息置于第一目标长TTI的控制信令中。
仍以第二目标长TTI为图1-1中的第23号长TTI为例,假设需要在第23号长TTI中调度3个短TTI,上述3个短TTI的长度相同,假设为1ms。每个短TTI的HARQ反馈资源紧邻该短TTI的尾部。则,设置在第22号长TTI的控制信令101中的短TTI的调度信息可以包括:位置信息:第23号长TTI;长度信息:1ms;数量信息:3;HARQ反馈资源的位置信息:紧邻每个短TTI的尾部。
在本公开另一实施例中,上述短TTI的调度信息也可以采用第一调度信息列表的形式,设置于第22号长TTI的控制信令101中,如以下表三所示:
位置信息 第23号长TTI
长度信息 1ms
数量信息 3
HARQ反馈资源的位置信息 紧邻每个短TTI的尾部
表三
第二种设置方式:将一个长TTI中第一个短TTI的调度信息设置于第一目标长TTI的控制信令中,后序短TTI的调度信息设置在第二目标长TTI中前一个短TTI的子控制信令中。
仍以第二目标长TTI为图1-1中的第23号长TTI为例,假设需要在第23号长TTI中调度3个短TTI,上述3个短TTI的长度相同,假设为1ms。每个短TTI的HARQ反馈资源紧邻该短TTI的尾部。
本公开中,可以在第22号长TTI的控制信令中设置第23号长TTI的第一个短TTI的调度信息,该调度信息除了包括第一个短TTI的位置信息即第23号长TTI、长度信息、数量信息、HARQ反馈资源的位置信息之外,还包括:指示信息,所述指示信息用于指示所述第一个短TTI中包含后序短TTI的调度信息。更具体的,该指示信息用于指示所述第一个短TTI的子控制信令中包含后序短TTI的调度信息。
示例性的,设置于第22号长TTI的控制信令101中的第一个短TTI的调度信息,可以采用第二调度信息列表进行记录,如表四所示:
位置信息 第23号长TTI
长度信息 1ms
数量信息 1
HARQ反馈资源的位置信息 紧邻短TTI的尾部
指示信息 Y
表四
如表四所示,指示信息Y,表示第23号长TTI的第一个短TTI中设置有第二短TTI的调度信息。
第二种情况,在所述第一目标长TTI的数据域中设置所述短TTI的调度信息,并在所述第一目标长TTI的控制信令中设置所述短TTI的调度信息的位置信息,所述位置信息用于指示所述短TTI的调度信息在当前长 TTI数据域中的存储位置。适用于通过ePDCCH(enhanced Physical Downlink Control Channel,增强型物理下行控制信道)承载控制信息的情况。
基于图1-1中所示的一个长TTI的结构示意图,第一设备还可以在第22号长TTI的数据域102中设置上述短TTI的调度信息。该情况下,第22号长TTI的控制信令101中还需要设置上述短TTI的调度信息的位置信息,用于指示短TTI的调度信息在数据域102中的存储位置。和上述第一种情况中调度信息的设置方式类似,第二种情况下也可以采用两种方式在长TTI的数据域中设置一个或多个短TTI的调度信息,此处不再赘述。
在步骤12中,通过所述第一目标长TTI将所述短TTI的调度信息发送给第二设备;
对应的,第二设备接收第一目标长TTI,并从中获取上述短TTI的调度信息。以便第二设备后续在接收到调度有短TTI的第二目标长TTI时,依据上述短TTI的调度信息从第二目标长TTI中获取短TTI,并将所述短TTI对应的HARQ反馈信息发送给上述第一设备。
在步骤13中,根据所述短TTI的调度信息在第二目标长TTI中调度短TTI并发送给所述第二设备;
此处需要说明的是,在一实施例中,第一目标长TTI、第二目标长TTI可以是同一个长TTI。在另一实施例中,第二目标长TTI也可以是第一目标长TTI之后的一个长TTI。
该步骤13具体为:根据短TTI的调度信息依次在第二目标长TTI中调度短TTI,并依次为每个短TTI分配HARQ反馈资源;将调度了短TTI的第二目标长TTI发送给第二设备。
对应于上述两种短TTI的调度信息的设置方式,步骤13中关于如何调度短TTI也可以至少包括两种实施方式。
第一种调度方式,当所述第一目标长TTI中设置了一个长TTI的所有短TTI的调度信息时,例如上述第一种设置方式,第一设备根据所述调 度信息在第二目标长TTI中依次调度每一个短TTI并依次为每一个短TTI分配HARQ反馈资源。参照图3-1,示例性地示出了依据上述表三所示的调度信息调度了3个短TTI后的第23号长TTI的结构示意图。根据调度信息中设置的第三个短TTI的HARQ反馈资源位置的不同,图3-2示例性地示出了调度了3个短TTI后的第23号长TTI的另一种结构示意图。图3-3示例性地示出了调度了1个短TTI后的一个长TTI的结构示意图。
第二种调度方式,当所述第一目标长TTI中仅设置了一个长TTI的第一个短TTI的调度信息时,参照图5根据一示例性实施例示出的另一种获取HARQ反馈信息的方法流程图,上述步骤13可以包括:
在步骤131中,根据所述第一个短TTI的调度信息,为第二目标长TTI调度第一个短TTI,并为所述第一个短TTI分配HARQ反馈资源;
在步骤132中,从所述第一个短TTI至倒数第二个短TTI,依次执行以下操作:在当前短TTI的子控制信令中设置后序短TTI的调度信息;依据所述后序短TTI的调度信息调度后序短TTI并为所述后序短TTI分配HARQ反馈资源。
其中,所述后序短TTI的调度信息至少包括:长度信息、HARQ反馈资源的位置信息、指示信息。
示例性地,仍以一个长TTI中需要调度三个短TTI为例,其中第一个短TTI的调度信息如上述表四所示。参照图6根据一示例性实施例示出的另一种获取HARQ反馈信息的方法流程图,上述步骤132可以具体包括:
在步骤1321中,在第一短TTI的子控制信令中设置第二短TTI的调度信息;
如上示例,第一设备根据表四所示的调度信息在第23号长TTI中调度完第一短TTI之后,可以在该第一短TTI的子控制信令中设置第二短TTI的调度信息。
其中,第二短TTI的调度信息可以与表四所示信息相同,或者,省略位置信息和数量信息,如表五所示:
长度信息 1ms
HARQ反馈资源的位置信息 紧邻短TTI的尾部
指示信息 Y
表五
表五与表四相比,调度信息的数据量变少,可以减少子控制信令的数据量,从而节约信道传输资源。
在步骤1322中,依据所述第二短TTI的调度信息为所述第二目标长TTI调度第二短TTI并分配HARQ反馈资源;
在步骤1323中,在所述第二短TTI的子控制信令中设置第三短TTI的调度信息;
示例性的,第三短TTI的调度信息可以如表六所示:
长度信息 1ms
HARQ反馈资源的位置信息 紧邻短TTI的尾部15
表六
与表五不同的是,表六中不含指示信息,表示第三短TTI中不设有后序短TTI的调度信息,即指示第一设备在第二目标长TTI中调度完第三短TTI之后不再调度其他短TTI。
在步骤1324中,根据所述第三短TTI的调度信息为第二目标长TTI调度第三短TTI并分配HARQ反馈资源。
由于第23号长TTI中不需要调度第四个短TTI,第三短TTI中可以不设置子控制信令。
上述步骤1321~1324示例性地描述了,如何在第二目标长TTI中设置后序短TTI的调度信息并调度短TTI的过程。
此处需要说明的是,若第二目标长TTI是第一目标长TTI之后的一个长TTI,第一设备也可以在设置完短TTI的调度信息之后,依据上述短 TTI的调度信息在第二目标长TTI中调度短TTI,然后将第一目标长TTI和调度了短TTI的第二目标长TTI依次发送给上述第二设备。
若第一目标长TTI、第二目标长TTI为同一个长TTI,则无需首先通过第一目标长TTI向上述第二设备发送上述短TTI的调度信息。
在步骤14中,接收所述第二设备依次在所述第二目标长TTI中发送的、每个所述短TTI的HARQ反馈信息。
第二设备在接收到第二目标长TTI之后,可以根据已获取的短TTI的调度信息依次解析每个短TTI。在每解析完一个短TTI之后,生成该TTI对应的HARQ反馈信息,并通过该短TTI对应的HARQ反馈资源将HARQ反馈信息发送给第一设备,使第一设备可以及时接收该短TTI的HARQ反馈信息,并根据该HARQ反馈信息判断是否需要重传该短TTI,减少短TTI的反馈时延,确保时延敏感业务数据优先送达。
相应的,本公开还提供了一种传输HARQ反馈信息的方法,应用于第二设备中。参照图7根据一示例性实施例示出的一种传输HARQ反馈信息的方法流程图,所述方法包括:
在步骤21中,从第一目标长TTI中获取短TTI的调度信息,所述调度信息至少包括:所述短TTI的位置信息、数量信息、长度信息、HARQ反馈资源的位置信息其中,所述HARQ反馈资源被所述第二设备用作向第一设备发送所述短TTI的HARQ反馈信息;
在第一设备依次向第二设备发送如图1-1所示的50个长TTI的过程中,第二设备不知道哪个长TTI中调度有短TTI,因此,第二设备需要首先获取第一设备在长TTI中设置的短TTI的调度信息,以便根据该短TTI的调度信息解析短TTI。
关于如何在接收长TTI的过程中,获取短TTI的调度信息,参照图8根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤21可以包括:
在步骤211中,监听每个长TTI中是否包含短TTI的调度信息,获 得监听结果;
第一设备在进行信息配置时,可能会在每个长TTI中设置控制信令,或者间隔性地设置控制信令。由于第二设备不确定哪个长TTI中设置有控制信令,也不确定短TTI的调度信息设置在哪个长TTI的控制信令中,因此,可以启动监听机制,实时监听每个长TTI中是否包含短TTI的调度信息,获得监听结果。
在步骤212中,当所述监听结果指示所述长TTI中包含所述短TTI的调度信息时,确定当前长TTI为第一目标长TTI;
本公开实施例中,第二设备的监听结果可以用一个字节0或1表示,比如,当上述监听结果为1时,指示当前长TTI中包含短TTI的调度信息,则确定当前长TTI为第一目标长TTI。
在步骤213中,从所述第一目标长TTI中解析所述短TTI的调度信息。
在确定了第一目标长TTI之后,可以从该长TTI的控制信令或数据域中解析短TTI的调度信息。
在步骤22中,根据所述短TTI的调度信息从第二目标长TTI中依次解析每个短TTI,并通过所述每个短TTI对应的HARQ反馈资源将HARQ反馈信息发送给第一设备。
第二设备首先根据短TTI的调度信息确定第二目标长TTI,然后依次从第二目标长TTI中逐个接收短TTI并反馈HARQ信息。
具体地,参照图9根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤22可以包括:
在步骤221中,根据所述短TTI的位置信息,确定调度有短TTI的第二目标长TTI;
假设第二设备在接收到的第22号长TTI中获取到了短TTI的调度信息,如上述表三所示。则,用户设备通过上述表三可知,第一设备在第23号长TTI中调度有短TTI。
在步骤222中,根据所述短TTI的长度信息和数量信息,从所述第二目标长TTI中获取每一个短TTI;
上述一个短TTI可以是第二目标长TTI中任意一个短TTI。
仍以表三所示的调度信息为例,第二设备会根据上述短TTI的长度信息和数量信息,从第23号长TTI中依次获取第一短TTI、第二短TTI、第三短TTI。
对于第一目标长TTI中仅包括了一个短TTI的调度信息的情况,参照图10根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤222可以包括:
在步骤2221中,当所述数量信息为1时,根据所述长度信息获取所述第二目标长TTI中的第一个短TTI;
即,第二设备从第一目标长TTI中获取短TTI的调度信息后,查看该调度信息中的数量信息,若上述数量信息为1,说明第二目标长TTI中至少调度了一个短TTI,可以依据调度信息中记录的短TTI的长度信息从第二目标长TTI中解析第一个短TTI。
至于第二目标长TTI调度了多少长TTI,可能包括两种情况,第一种情况,第二目标长TTI中仅调度了一个短TTI,如图3-3所示;第二种情况,第二目标长TTI中包括至少两个短TTI,只是后序TTI的调度信息没有设置在第一目标长TTI中。
为了判断第二目标长TTI中是否调度有多个短TTI,从第一个短TTI开始,依次执行以下步骤2222~2224。
在步骤2222中,判断当前短TTI的调度信息中是否包括指示信息,所述指示信息用于指示当前短TTI中包含后序短TTI的调度信息;若是,执行步骤2223;若否,执行步骤2225。
示例性地,假设第二目标长TTI为第23号长TTI,则上述第一个短TTI的指示信息用于指示第23号长TTI的第一个短TTI中包含后序短TTI的调度信息。
在步骤2223中,若所述当前短TTI的调度信息中包括所述指示信息,从已获取的当前短TTI中解析后序短TTI的调度信息;
如上,从第一短TTI中获取第二短TTI的调度信息,具体地,可以从第一短TTI的子控制信令中,获取第二短TTI的调度信息。
在步骤2224中,根据所述后序短TTI的调度信息,从所述第二目标长TTI中解析后序短TTI;
在步骤2225中,若所述当前短TTI的调度信息中不包括所述指示信息,停止从所述第二目标长TTI中解析短TTI。
在步骤223中,对所述短TTI的数据包进行检错,生成相应的HARQ反馈信息;上述HARQ反馈信息可以是ACK信号或NACK信号。
假设第二设备当前获取的一个短TTI是第23号长TTI的第一短TTI,对上述第一短TTI的数据包进行检错,获得HARQ反馈信息。
在步骤224中,根据所述HARQ反馈资源的位置信息,将所述短TTI的HARQ反馈信息通过指定的HARQ反馈资源发送给所述第一设备。
如上,第二设备在生成第一短TTI的HARQ反馈信息之后,根据表三中记录的HARQ反馈资源的位置信息,通过第23号长TTI中、紧邻第一短TTI尾部的HARQ反馈资源,如图3-1中的HARQ反馈资源203,将第一短TTI的HARQ反馈信息发送给第一设备。
在本公开另一实施例中,为第一短TTI的HARQ反馈信息指定的HARQ反馈资源也可以不是紧邻第一短TTI的HARQ反馈资源。
可见,采用本公开提供的传输HARQ反馈信息的方法,第二设备在接收非时延敏感的业务数据时,若需要获取时延敏感业务数据,第二设备可以从第一设备及时接收到用于传输时延敏感业务数据的短TTI,并能及时向第一反馈上述短TTI的反馈信息,从而及时获取到时延敏感业务数据,减少时延敏感业务数据的传输时延,提升设备性能。
对于前述的各方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本公开并不受所描述的动作 顺序的限制,因为依据本公开,某些步骤可以采用其他顺序或者同时进行。
其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于可选实施例,所涉及的动作和模块并不一定是本公开所必须的。
