Description

数据传输方法、 装置和设备
技术领域
本发明实施例涉及通信技术领域, 尤其涉及一种数据传输方法、 装置 和设备。 背景技术
混合自动重传 (Hybrid Automatic Repeat Request, 以下简称 HARQ ) 中常用的一种方式是停等式, 即发送端每发送一个数据包就暂时停下来, 等 待接收端的确认信息; 当数据包到达接收端时, 接收端对其进行检错, 若所 接收的数据包正确, 返回确认应答 (Acknowledgment, 以下简称 ACK) 信号, 若所接收的数据包错误, 则返回否认应答 (Negative Acknowledgement , 以 下简称 NACK)信号。 当发端收到 ACK信号, 就发送新的数据, 否则重新发送 上次传输的数据包。 因此, 一个 HARQ进程为数据的传输到数据的 ACK反馈或 NACK 反馈的过程。 长期演进 (Long Term Evolution, 以下简称 LTE) 系统 采用了 8进程的停等式协议, 即发送端在信道上并行地运行 8个不同的停等 式进程,数据发送端在接收到前一个 HARQ进程的反馈消息前会向数据接收端 发送另一个 HARQ进程的数据块。 除此之外, 数据发送端发送一个 HARQ进程 数据的发送时刻和接收到该进程数据的 HARQ-ACK 反馈时刻之间的时序关系 是预设的。 gP, 数据发送端在接收到某一个 HARQ进程的 HARQ-ACK反馈后, 可以根据该进程数据的传输时刻和 HARQ-ACK 反馈之间的预设时序关系确定 出该 HARQ-ACK是针对哪一个 HARQ进程的。
为了得到更大的传输带宽, LTE 系统引入了载波聚合技术。 对于基站间 的载波聚合, 由于基站间的非理想回传 (Non Ideal Reverberation) , 使得 隶属于不同基站的多个下行载波间的数据调度是独立进行的, 因此, 用户设 备 (User Equiment , 以下简称 UE) 工作在基站间的载波聚合系统中时, 需 要对多个基站的下行数据传输分别发送 HARQ-ACK反馈,而不能采用理想回传 ( Ideal Reverberation) 情况下将多个基站的 HARQ-ACK反馈给一个基站的 方式。 但可能存在一类能力较低的 UE, 该类 UE的上行发送不能同时工作在 多个演进型基站 (evolved Node B, 以下简称 eNB ) 对应的载波上, 每个时 刻只能工作在一个 eNB对应的上行载波上。 该类 UE工作在上述 eNB间的 CA 系统中时, 对多个基站的上行数据传输只能采用时分的方式, 从而使得多个 基站均获知各自的下行数据传输的 HARQ-ACK反馈情况。
然而, 由于数据发送端发送一个 HARQ进程数据的发送时刻和接收到该进 程数据的 HARQ-ACK反馈时刻之间的时序关系是预设的。为了遵循此预设的时 序关系,数据接收端采用时分方式为多个基站之间反馈 HARQ-ACK将使得基站 在某一时刻对下行载波的调度也满足相应的时分方式, 从而造成载波聚合系 统的频谱资源不能得到充分的利用, 进而导致用户的峰值传输速率受限。 发明内容

为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对 实施例或现有技术描述中所需要使用的附图作一简单地介绍, 显而易见 地, 下面描述中的附图是本发明的一些实施例, 对于本领域普通技术人员 来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附 图。

为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本 发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描 述, 显然,所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提 下所获得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例中的数据发送端可以为基站, 也可以为其他的数据收发 设备; 数据接收端可以为 UE , 也可以为其他的收发设备, 本发明实施例对 此不做限制。
为了明确本发明实施例的方法所适用的场景, 此处对本发明实施例适 用的场景作一简要的介绍, 需要注意的是, 这里的数据接收端均以 UE举 例, 数据发送端均以基站举例, 但本发明实施例并不限制于此:
对于基站间的载波聚合系统 (包含多个成员载波, 即后面所提到的载 波 1和载波 2 ), 第一基站和第二基站分别通过各自的下行载波对 UE进行 下行数据调度(即在相应的下行载波上向 UE发送 HARQ进程数据); 其中, 第一基站的下行载波为载波 1, 第二基站的下行载波为载波 2 ; 如果两个 基站之间是非理想回传连接, 第一基站仅知道载波 1上的数据进程调度情 况和 HARQ-ACK信息传输资源的映射关系, 却不知道载波 2的数据进程调 度情况和 HARQ-ACK信息传输资源, 第一基站无法通过接收 UE的上行信号 获知第二基站发送的数据进程对应的 HARQ-ACK信息, 也无法将载波 2对 应的 HARQ-ACK信息发送给第二基站。 为了避免上述问题, 可以使 UE采用 时分方式为多个基站之间发送 HARQ-ACK信息, 即将不同载波的 HARQ进程 数据对应的 HARQ-ACK信息分时刻发送给相应的基站。但是上述 UE的分时 发送 HARQ-ACK信息会带来限制基站对 UE的调度的问题, gp, 在某些时刻 会限制基站使用成员载波中的某一个载波对 UE进行下行数据调度, 进而 使得 UE不能同时工作在多个下行载波上, 从而使得载波聚合的频谱资源 不能充分被利用, 这里以一个简单的例子来说明: 假设第一基站在载波 1 且在第 N时刻发送 HARQ-ACK进程数据, 按照现有技术数据发送端发送一 个 HARQ进程数据的发送时刻和接收到该进程数据的 HARQ-ACK反馈时刻之 间的时序关系是预设的, 即应该在第 N+K时刻接收到 UE发送的该 HARQ进 程数据的 HARQ-ACK信息, 但是在第 N+K时刻 UE却在第二基站的上行载波 上向第二基站发送载波 2上的 HARQ进程数据对应的 HARQ-ACK信息, 因此 第一基站在第 N时刻在载波 1对 UE进行下行数据调度得不到肯定的 HARQ-ACK信息而变成无效的传输。
为了解决上述基站对 UE的调度限制问题, 本发明实施例提供了如下 的方法:
图 1为本发明提供的数据传输方法实施例一的流程示意图, 本发明实 施例的执行主体为数据接收端, 如图 1所示, 该方法包括: S101:接收数据发送端在第 N时刻发送的第 P个 HARQ进程数据;其中, P为大于等于 1的正整数, N为大于等于 1的正整数。
具体的, 数据发送端在第 N时刻向数据接收端发送第 P个 HARQ进程 数据, 并且, 在第 N时刻之前的时间, 数据发送端也向数据接收端发送了 P-1个 HARQ进程数据; 其中, P为大于等于 1的正整数, N为大于等于 1 的正整数。 需要注意的是, 上述 P-1个 HARQ进程数据对应的 HARQ-ACK信 息可能存在以下三种情况:
第一种: 数据接收端向数据发送端反馈了 P-1个 HARQ进程数据中的 部分 HARQ进程数据对应的 HARQ-ACK信息;
第二种: 数据接收端向数据发送端反馈了上述 P-1个 HARQ进程数据 对应的所有的 HARQ-ACK信息;
第三种: 数据接收端向数据发送端未反馈上述 P-1个 HARQ进程数据 对应的任何一个 HARQ-ACK信息。
S102 : 在第 M时刻向数据发送端发送 Q个 HARQ数据对应的 HARQ-ACK 信息; 其中, 该 Q个 HARQ进程数据对应的 HARQ-ACK信息为所述第 M时刻 前未向数据发送端发送 HARQ-ACK信息的 HARQ进程数据对应的反馈, 上述 Q个 HARQ进程数据对应的 HARQ-ACK信息中包括与上述第 P个 HARQ进程数 据对应的第 P个 HARQ-ACK信息, M为大于 N的正整数。
具体的, 数据接收端在接收到数据发送端发送的第 P个 HARQ进程数 据之后, 对该第 P个 HARQ进程数据进行解调、 译码等处理, 并判断该第 P 个 HARQ进程数据是否被正确接收。并且, 在第 M时刻向数据发送端发送 Q 个 HARQ-ACK信息; 其中, 该 Q个 HARQ进程数据对应的 HARQ-ACK信息为 数据接收端在第 M时刻前未向数据发送端发送 HARQ-ACK信息的 HARQ进程 数据对应的反馈,需要注意的是,上述 Q个 HARQ进程数据对应的 HARQ-ACK 信息可以为数据接收端在第 M时刻前未向数据发送端发送 HARQ-ACK信息 的全部 HARQ进程数据 (Q个 HARQ进程数据) 对应的反馈, 也可以为数据 接收端在第 M时刻前未向数据发送端发送 HARQ-ACK信息的部分 HARQ进程 数据 (这里的部分 HARQ进程数据的个数是大于 1的) 对应的反馈。 并且, 上述第 P个 HARQ进程对应的反馈 HARQ-ACK信息也包含在上述 Q个
HARQ-ACK信息中。 为了和本实施例中所描述的 P_l个 HARQ进程数据对应 的 HARQ-ACK信息对应起来理解技术方案, 该 Q个 HARQ进程数据对应的 HARQ-ACK信息可以是上述数据接收端向数据发送端反馈的 P-1个 HARQ进 程数据中的部分 HARQ进程数据对应的 HARQ-ACK信息; 还可以是数据接收 端向数据发送端反馈的上述 P-1个 HARQ进程数据对应的所有的 HARQ-ACK 信息。
也就是说, 数据接收端将在第 M时刻将之前未向数据发送端发送 HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK信息都一起发送给数据发 送端。 因而, 数据发送端在没有接收到 HARQ进程相应的 HARQ-ACK信息时 还可以继续在相应的载波上检测这些 HARQ进程数据对应的 HARQ-ACK信 息, 即数据发送端对这些 HARQ进程数据的调度仍然是有效的。
本发明实施例提供的数据传输方法, 数据接收端接收数据发送端在第 N时刻发送的第 P个 HARQ进程数据, 数据接收端在第 M时刻发送包含第 P 个 HARQ进程对应的第 P个 HARQ-ACK信息的 Q个 HARQ进程数据对应的 HARQ-ACK信息,并且该 Q个 HARQ进程的 HARQ-ACK信息为上述第 M时刻前 未向数据发送端反馈 HARQ-ACK信息的 HARQ进程中的部分或全部 HARQ进 程数据对应的反馈, 从而使得数据发送端在多个下行载波上同时为数据接 收端发送 HARQ进程数据有效, 进而使得载波聚合系统的频谱资源能够得 到充分利用, 提高了用户的峰值传输速率。
进一步地, 在上述图 1所示实施例的基础上, 作为本发明实施例的一 种可行的实施方式, 本实施例提供的方法涉及的是数据发送端为数据接收 端配置相应的 HARQ-ACK信息传输资源的过程。可选的,在 S101之后, S102 之前, 上述方法还包括: 接收所述数据发送端为所有 HARQ进程数据配置 的 HARQ-ACK信息传输资源集合,且每个 HARQ进程数据对应一个 HARQ-ACK 信息传输资源。
具体的, 数据发送端会给自身所要发送的所有的 HARQ进程数据配置 对应的 HARQ-ACK信息传输资源, 构成一个 HARQ-ACK信息传输资源集合; 其中,一个 HARQ进程数据对应一个特定的 HARQ-ACK信息传输资源,该 HARQ 进程数据对应的 HARQ-ACK信息就在该对应的特定的 HARQ-ACK信息传输资 源上传输。 可选的, 数据发送端可以通过高层信令将用于指示上述
HARQ-ACK信息传输资源集合的信息发送给数据接收端,还可以通过其他的 方式将上述用于指示 HARQ-ACK信息传输资源集合的信息发送给数据接收 端, 本发明实施例对此不做限制。 上述一个特定的 HARQ-ACK信息传输资 源指的是发送该进程数据的 HARQ-ACK需要的 HARQ-ACK信息传输资源, 根 据该进程的数据传输方式等不同, 上述 HARQ-ACK信息的传输资源大小可 以不同。
数据接收端接收数据发送端配置的所有的 HARQ进程数据的 HARQ-ACK 信息传输资源, 同时可以按照下列方式反馈 Q个 HARQ-ACK信息。 需要说 明的是, 以下方式只是在第 M时刻反馈 Q个 HARQ-ACK信息的可能, 实际 的实现方式不限于此: 在 LTE系统中, 可以采用类似物理上行控制信道格 式 3 ( Phys ical Upl ink Control Channel format, 以下简禾尔 PUCCH format 3 ) 的形式, 该 PUCCH format 3支持 48个编码比特; 同时使用类似的格 式还可以定义 PUCCH format4 , 该 PUCCH format4的格式中, 48比特中的 部分或全部比特用来为数据接收端所有 HARQ进程数据中的每个 HARQ进程 数据配置特定的 HARQ-ACK信息传输资源, 并且每个 HARQ进程数据所配置 的特定的 HARQ-ACK信息传输资源可以传输 HARQ-ACK消息的 ACK、 NACK、 非连续发送 ( Di scont inuous Transmi ss ion , 以下简称 DTX ) 三种状态。 对于数据发送端来说, HARQ-ACK信息的 DTX状态和没有检测到 HARQ-ACK 信息相当。 该 PUCCH format4所在的资源也可以由数据发送端向数据接收 端指示。 数据接收端在接收到数据发送端发送的第 P个 HARQ进程数据时, UE会在前述 HARQ-ACK信息传输资源集合中选择相应的 Q个 HARQ进程数据 对应的 Q个特定的 HARQ-ACK信息传输资源,并在该些 Q个特定的 HARQ-ACK 信息传输资源中携带上述所确定的 Q个 HARQ进程数据的 HARQ-ACK信息发 送至发送端, 并且在所有 HARQ进程数据对应的特定的 HARQ-ACK信息传输 资源中除所述的 Q个特定的 HARQ-ACK信息传输资源外的其他资源上发送 DTX状态消息至发送端。可选的,该 Q个 HARQ-ACK信息传输资源包括时间、 频率、 码域、 空域等无线资源。
进一步地, 在上述实施例的基础上, 上述第 P个 HARQ进程数据对应 第 P个 HARQ-ACK信息检测窗口, 该第 P个 HARQ-ACK信息检测窗口为用于 上述数据发送端检测第 P个 HARQ-ACK信息的时间长度, 则在第 M时刻向 数据发送端发送 Q个 HARQ数据对应的 HARQ-ACK信息, 包括: 在第 P个 HARQ-ACK信息检测窗口对应的发送时间内将 Q个 HARQ进程数据对应的 HARQ-ACK信息发送至数据发送端; 其中, 上述第 M时刻为在上述第 P个 HARQ - ACK信息检测窗口对应的发送时间内预设的发送时刻。
具体的, 在本发明实施例中, 上述第 P个 HARQ进程数据对应第 P个 HARQ-ACK信息检测窗口, 该第 P个 HARQ-ACK信息检测窗口为数据发送端 检测第 P个 HARQ-ACK信息的时间长度 (该时间长度为一个时间范围) , 即第 P个 HARQ-ACK信息检测窗口是从数据发送端检测第 P个 HARQ-ACK信 息的时间来定义的, 该第 P个 HARQ-ACK信息检测窗口对应的是数据发送 端的检测时间段; 另一方面, 上述第 P个 HARQ-ACK信息检测窗口对应的 发送时间是从数据接收端来定义的发送时间, 即数据接收端在该发送时间 内发送的第 P个 HARQ-ACK信息到达数据发送端, 数据发送端在第 P个 HARQ-ACK信息检测窗口是可以检测到的, 也就是说, 在上述发送时间内的 某一时刻发送第 P个 HARQ-ACK信息并加上该第 P个 HARQ-ACK信息到达数 据发送端的传输时间, 落在了数据发送端第 P个 HARQ-ACK信息检测窗口 内。因此,数据接收端在 Q个 HARQ-ACK信息传输资源上发送 Q个 HARQ-ACK 信息给数据发送端是在该第 P个 HARQ-ACK信息检测窗口时间段对应的数 据接收端的发送时间段内进行的, 上述数据接收端发送 Q个 HARQ进程数 据的 HARQ-ACK信息的第 M时刻属于上述发送时间内的固定时刻, 且这个 固定时刻可以是由数据发送端和数据接收端约定的发送时刻。
另外, 需要说明的是, 上述第 P个 HARQ-ACK信息检测窗口的起始时 刻为上述数据发送端检测上述第 P个 HARQ-ACK信息的开始时刻。
为了更好地理解本发明实施例中的方法, 在这里以图 2所示的内容为 例做一具体的说明, 参见图 2 :
具体的,图 2示意的无线子帧包括 20个传输时间间隔(Transmi ssion Time Interval , 以下简称 TTI ) 。 可选的, 数据发送端有 D0〜D7的 8个 HARQ进程数据在不同的 TTI被数据发送端调度, 即数据发送端在不同的 TTI向数据接收端发送 DCTD7的 HARQ进程数据;数据接收端只有在第 6TTI、 第 8ΤΤΙ、 第 10ΤΤΙ、 第 19TTI向数据发送端发送 HARQ-ACK信息。 特别地, 数据接收端可以向数据发送端发送 HARQ-ACK的信息的时刻是数据发送端 和数据接收端预先约定的时间资源。前述的第 M时刻即就是第 6TTI ; 数据 发送端的每个 HARQ进程数据的 HARQ-ACK检测窗口长度优选为 8TTI,但本 发明对此并不做限制。
参照图 2所示, 数据发送端的 8个 HARQ进程数据在不同的 TTI被调 度, 具体为: 在第 0TTI , 调度 DO; 在第 1TTI , 调度 D1 ; 在第 2TTI , 调度 D2 ; 在第 3TTI , 调度 D3 ; 在第 4TTI , 调度 D4; 在第 6TTI , 调度 D5; 在 第 7TTI , 调度 D6; 在第 10TTI , 调度 D7; 在第 11TTI , 调度 DO等; 数据 接收端只有在第 6TTI、 第 8ΤΤΙ、 第 10ΤΤΙ、 第 19TTI可以向数据发送端发 送 HARQ-ACK信息。 假设数据发送端在第 0TTI调度 DO , 并且在 3个 TTI 后即第 4TTI时, 数据接收端没有发送 DO对应的 HARQ-ACK信息给数据发 送端; 同时, 假设数据发送端在第 1TTI调度 D1 , 并且在 3个 TTI后即第 5TTI时, 数据接收端也没有发送 D1对应的 HARQ-ACK信息给数据发送端; 而在第 2TTI数据发送端调度 D2 , 并且在 3个 TTI后即第 6TTI时, 数据接 收端将 D2对应的 HARQ-ACK信息发送给数据发送端, 同时还将前面 DO和 D1对应的 HARQ-ACK信息一起发送给数据发送端, 这里的 D0、 Dl、 D2对应 的 HARQ-ACK信息即就是前面提到的 Q个 HARQ进程数据对应的 HARQ-ACK 信息。
数据接收端在发送 HARQ-ACK信息后, 数据发送端在各进程对应的 HARQ-ACK信息检测窗口内检测各进程对应的 HARQ-ACK信息。 此时需要注 意的是,数据发送端的 DO和 D1虽然没有在相应的时刻(DO对应的 HARQ-ACK 信息的接收时刻为第 4TTI,D1对应的 HARQ-ACK信息的发送时刻为第 5TTI ) 接收到自身所对应的 HARQ-ACK信息, 但是, 本发明实施例引入了上述 HARQ-ACK信息检测窗口, 即数据发送端可以在 DO和 D1对应的 HARQ-ACK 信息检测窗口内分别继续检测 DO和 Dl的 HARQ-ACK信息, 即检测的时间 从一个时刻变为一个时间长度, 而发送 D0、 Dl、 D2对应的 HARQ-ACK信息 的第 6TTI则在 Dl、 Dl、 D2对应的 HARQ-ACK信息检测窗口内, 则数据发 送端可以检测到上述 D0、 Dl、 D2对应的 HARQ-ACK信息。 数据接收端反馈 第 P个 HARQ进程数据的 HARQ-ACK信息时,需要使该 HARQ-ACK信息在第 P 个 HARQ进程数据的 HARQ-ACK信息检测窗口内到达数据发送端, 否则, 数 据接收端放弃该第 P个 HARQ进程数据的 HARQ-ACK信息反馈。 如图 2中, 即使第 19TTI上数据接收端可以发送 HARQ-ACK信息, 但对 D6来说, 数据 接收端可以预见对 D6的 HARQ-ACK信息在到达数据发送端时会超出 D6的 HARQ-ACK信息检测窗口, 则数据接收端在第 19TTI上放弃发送 D6对应的 HARQ-ACK信息。
需要注意的是, 第 P个 HARQ-ACK数据的 HARQ信息检测窗口的起始时 刻为该数据发送端发送该第 P个 HARQ进程数据到达数据接收端的传输时 间、 且数据接收端对该 HARQ进程数据进行处理的时间以及最后数据接收 端将该 HARQ进程数据对应的 HARQ-ACK信息发送给数据发送端的最早时 亥 lj。 例如: 如上所述, 数据发送端在发送 D2后, 经过 3个 TTI时间后 (即 第 6TTI ) 为该 HARQ-ACK信息检测窗口的起始时刻, 这 3个 TTI的时间即 就是数据发送端发送的 HARQ进程数据到达数据接收端的传输时间和数据 接收端对该 HARQ进程数据进行处理的时间以及数据接收端将该 HARQ进程 数据对应的 HARQ-ACK信息发送给数据发送端所需要的时间。
本发明实施例提供的数据传输方法, 数据接收端接收数据发送端在第 N时刻发送的第 P个 HARQ进程数据, 数据发送端在第 M时刻发送包含第 P 个 HARQ进程对应的第 P个 HARQ-ACK信息的 Q个 HARQ进程数据对应的 HARQ-ACK信息,并且该 Q个 HARQ进程数据对应的 HARQ-ACK信息为上述第 M时刻前未向数据发送端反馈 HARQ-ACK信息的 HARQ进程中的部分或全部 进程对应的反馈, 从而使得数据发送端可以同时在多个下行载波上为数据 接收端发送 HARQ进程数据有效, 进而使得载波聚合系统的频谱资源能够 得到充分利用, 提高了用户的峰值传输速率。 图 3为本发明提供的数据传输方法实施例二的流程示意图, 本发明的 执行主体是数据发送端, 如图 3所示, 该方法包括:
S301 : 在第 N时刻向数据接收端发送第 P个 HARQ进程数据; 其中, 所述 P为大于等于 1的正整数, 所述 N为大于等于 1的正整数。
具体的, 数据发送端在第 N时刻向数据接收端发送第 P个 HARQ进程 数据, 并且, 在第 N时刻之前的时间, 数据发送端也向数据接收端发送了 P- 1个 HARQ进程数据; 其中, P为大于等于 1的正整数, N为大于等于 1 的正整数。
S302 : 接收数据接收端在第 M时刻发送的 Q个 HARQ进程数据对应的 HARQ-ACK信息; 其中, 该 Q个 HARQ-ACK信息为第 M时刻前数据接收端未 向数据发送端发送 HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK反馈, 该 Q个 HARQ-ACK信息中包括与上述第 P个 HARQ进程数据对应的第 P个 HARQ-ACK信息, M为大于 N的正整数。
具体的, 数据接收端在接收到数据发送端发送的第 P个 HARQ进程数 据之后, 对该第 P个 HARQ进程数据进行解调、 译码等处理, 并判断该第 P 个 HARQ进程数据是否被正确接收。 并且在第 M时刻向数据发送端发送 Q 个 HARQ-ACK信息; 其中, 该 Q个 HARQ进程数据的 HARQ-ACK信息为所述 第 M时刻前数据接收端未向数据发送端发送 HARQ-ACK信息的 HARQ进程数 据对应的反馈, 需要注意的是, 上述 Q个 HARQ进程数据对应的 HARQ-ACK 信息可以为数据接收端在第 M时刻前未向数据发送端发送 HARQ-ACK信息 的全部 HARQ进程数据 (Q个 HARQ进程数据) 对应的反馈, 也可以为数据 接收端在第 M时刻前未向数据发送端发送 HARQ-ACK信息的部分 HARQ进程 数据 (该部分 HARQ进程数据的个数大于等于 1 )对应的反馈。 并且, 上述 第 P个 HARQ进程对应的 HARQ-ACK信息也包含在上述 Q个 HARQ-ACK信息 中。 也就是说, 数据接收端在第 M时刻将之前未向数据发送端发送
HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK信息都一起发送给数据发 送端。 因而, 数据发送端在没有接收到 HARQ进程相应的 HARQ-ACK信息时 还可以继续在相应的载波上检测这些 HARQ进程数据的 HARQ-ACK信息, 即 数据发送端对这些 HARQ进程数据的调度仍然是有效的。
本发明实施例提供的数据传输方法, 数据接收端接收数据发送端在第 N时刻发送的第 P个 HARQ进程数据, 数据接收端在第 M时刻发送包含第 P 个 HARQ-ACK信息的 Q个 HARQ进程数据对应的 HARQ-ACK信息, 并且该 Q 个 HARQ进程数据对应的 HARQ-ACK信息为上述第 M时刻前数据接收端未向 数据发送端发送 HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK反馈, 从而使得数据发送端在多个下行载波上同时为数据接收端发送 HARQ进程 数据有效, 进而使得载波聚合系统的频谱资源能够得到充分利用, 提高了 用户的峰值传输速率。
进一步地, 在上述图 3所示实施例的基础上, 作为本发明实施例的一 种可行的实施方式, 本实施例提供的方法涉及的是数据发送端为数据接收 端配置相应的 HARQ-ACK信息传输资源的过程。可选的,在 S301之后, S302 之前, 上述方法还包括: 为上述数据接收端配置所有 HARQ进程数据对应 的 HARQ-ACK信息传输资源集合,且每个 HARQ进程数据对应一个 HARQ-ACK 信息传输资源; 并发送用于指示上述 HARQ-ACK信息传输资源集合的信息 给数据接收端。
具体的, 数据发送端会给自身所要发送的所有的 HARQ进程数据配置 对应的 HARQ-ACK信息传输资源, 构成一个 HARQ-ACK信息传输资源集合, 并将用于指示该 HARQ-ACK信息传输资源集合的信息发送给上述数据接收 端, 可选的, 数据发送端可以通过高层信令将用于指示上述 HARQ-ACK信 息传输资源集合的信息发送给数据接收端, 还可以通过其他的方式将上述 用于指示 HARQ-ACK信息传输资源集合的信息发送给数据接收端, 本发明 实施例对此不做限制。 其中, 一个 HARQ-ACK信息传输资源指的是发送该 HARQ进程数据对应的 HARQ-ACK信息所需要的 HARQ-ACK信息传输资源,根 据该进程的数据传输方式等不同, 上述 HARQ-ACK信息传输资源大小可以 不同。 一个 HARQ进程数据的 HARQ-ACK信息就在该 HARQ数据对应的特定 的 HARQ-ACK信息传输资源上传输。
因而, 数据接收端在接收数据发送端配置的 HARQ-ACK信息传输资源 的集合时, 并且在接收到数据发送端发送的第 P个 HARQ进程数据时, UE 会在前述 HARQ-ACK信息传输资源集合中选择相应的 Q个 HARQ进程数据对 应的 Q个特定的 HARQ-ACK信息传输资源, 将前述未向数据发送端反馈 HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK信息携带在上述所确定的 Q个特定的 HARQ-ACK信息传输资源上在第 M时刻发送数据发送端。数据发 送端接收上述数据接收端在第 M时刻, 并且在上述 Q个 HARQ进程数据对 应的 Q个 HARQ-ACK信息传输资源上发送的 Q个 HARQ进程数据对应的 Q个 HARQ-ACK信息。 可选的, 该 Q个 HARQ-ACK信息传输资源包括时间、 频率、 码域、空域等无线资源;在 LTE系统中,可以采用类似 PUCCH PUCCH format 3的形式, 该 PUCCH format 3支持 48个编码比特。 使用类似的格式还可 以定义 PUCCH format4, 该 PUCCH format4的格式中, 48比特中的部分或 全部比特用来为数据接收端配置所有 HARQ进程数据对应的特定的
HARQ-ACK信息传输资源。 上述 PUCCH format4所在的时频资源也可以由数 据发送端向数据接收端指示。
进一步地, 在上述实施例的基础上, 作为本发明实施例的另一种可行 的实施方式, 本实施例涉及的方法是数据发送端在第 P个 HARQ进程数据 对应的 HARQ-ACK信息检测窗口检测第 P个 HARQ-ACK信息的过程。可选的, 在 S302之后, 该方法还包括: 在第 P个 HARQ进程数据对应的 HARQ-ACK 信息检测窗口内检测第 P个 HARQ进程数据对应的第 P个 HARQ-ACK信息。
具体的, 数据发送端接收数据接收端在第 M时刻发送的 Q个 HARQ进 程数据对应的 Q个 HARQ-ACK信息, 并且第 P个 HARQ进程数据对应的第 P 个 HARQ-ACK信息也包括在其中; 数据发送端在第 P个 HARQ-ACK信息检测 窗口检测第 P个 HARQ-ACK信息, 具体为: 若检测到第 P个 HARQ进程数据 对应的第 P个 HARQ-ACK信息, 则根据第 P个 HARQ-ACK信息的指示确定上 述第 P个 HARQ进程数据的应答消息(即确定第 P个 HARQ进程数据发送成 功) ; 或者, 若没有检测到第 P个 HARQ进程数据对应的第 P个 HARQ-ACK 信息, 则判断上述第 P个 HARQ进程数据发送失败。 同时, 若数据发送端 在第 N时刻前发送的前述 P-1个 HARQ进程数据各自对应的 HARQ-ACK信息 检测窗口也检测接收到了前述 P-1个 HARQ进程数据对应的 P-1个
HARQ-ACK信息。
这里存在一种情况, 数据发送端可能接收到前述 P-1个 HARQ进程数 据中的部分 HARQ进程数据对应的 HARQ-ACK信息, 因此在后面的检测过程 中只在未接收到 HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK信息检 测窗口检测。
需要注意的是, 上述第 P个 HARQ进程数据对应第 P个 HARQ-ACK信息 检测窗口, 该第 P个 HARQ-ACK信息检测窗口为数据发送端检测第 P个 HARQ-ACK信息的时间长度(该时间长度为一个时间范围) , 即本发明实施 例中数据发送端检测 HARQ-ACK信息的时间由原来的时刻更改为一个时间 段, 只要在这个时间段内数据发送端检测到前述未接收到 HARQ-ACK信息 的 HARQ进程数据对应的反馈 (即 HARQ-ACK信息) , 则数据发送端不会对 数据接收端的下行数据调度进行限制。
另外, 上述第 P个 HARQ-ACK信息检测窗口的起始时刻为上述数据发 送端检测上述第 P个 HARQ-ACK信息的开始时刻。 本发明实施例提供的数据传输方法, 数据接收端接收数据发送端在第
N时刻发送的第 P个 HARQ进程数据, 数据接收端在第 M时刻发送包含第 P 个 HARQ-ACK信息的 Q个 HARQ进程数据对应的 HARQ-ACK信息, 并且该 Q 个 HARQ进程数据对应的 HARQ-ACK信息为上述第 M时刻前数据接收端未向 数据发送端发送 HARQ-ACK信息的 HARQ进程数据对应的 HARQ-ACK反馈, 从而使得数据发送端在多个下行载波上同时为数据接收端发送 HARQ进程 数据有效, 进而使得载波聚合系统的频谱资源能够得到充分利用, 提高了 用户的峰值传输速率。
