Description

数据包接收状态的反馈方法、 发送节点及接收节点 技术领域
本发明涉及通信技术领域, 尤其涉及一种数据包接收状态的反馈方法、 发送节点及接收节点。 背景技术
传统无线网络中, 接收节点和发送节点是一对一的, 即一个接收节点只 从一个发送节点接收数据包。 为保证数据包的成功接收, 接收节点在接收到 数据包后, 需要向发送节点反馈数据包接收状态, 该数据包接收状态表明接 收节点是否成功接收了该数据包。 发送节点根据接收节点反馈的数据包接收 状态, 确定是否需要重新发送该数据包。
为提高网络的移动性能、 网络吞吐量等, 一对一的网络架构已逐渐演变 成一对多的网络架构, 即接收节点和发送节点是一对多的, 接收节点可以从 两个或两个以上的发送节点接收数据包。 为保证数据包的成功接收, 同样需 要进行数据包接收状态的反馈。 但是, 一对多的网络架构中, 可能存在接收 节点无法直接向某些发送节点发送消息的情况。 例如, 网络架构中存在接收 节点 1、 发送节点 A与发送节点 B, 发送节点 A发送数据包 a, 发送节点 B 发送数据包 b, 接收节点 1仅与发送节点 B之间有上行连接。 此时, 接收节 点 1使用不同的逻辑信道将数据包 a与数据包 b的接收状态都发送给发送节 点 B, 发送节点 B根据接收节点 1所使用的逻辑信道来区分哪个接收状态是 数据包 a的。 然后, 发送节点 B将数据包 a的接收状态发送给发送节点 A, 使得发送节点 A根据数据包 a的接收状态确定接收节点 1是否成功接收了数 据包 a。
然而, 由于能力的限制, 接收节点能支持的逻辑信道的数量是有限的。 当需要区分的发送节点数量超过接收节点所支持的逻辑信道的数量时, 接收 节点就无法正确的反馈每一个发送节点所需的数据包接收状态。 发明内容 本发明实施例提供一种数据包接收状态的反馈方法、 发送节点及接收节 点, 实现一对多的网络架构中, 接收节点能够不受逻辑信道数量的限制而正 确的反馈每一个发送节点的数据包的接收状态的目的。

图 1为本发明数据包接收状态的反馈方法实施例一的流程图。本实施 里的执行主体为接收节点, 适用于一对多的网络架构。 具体的, 本实施里 包括如下步骤:
101、接收节点接收第一节点发送的第一数据包与第二节点发送的第二数 据包, 第一节点为直接接收接收节点反馈的接收状态信息的发送节点, 第二 节点为不直接接收接收节点反馈的接收状态信息的发送节点。
一对多的网络架构中, 发送节点一般分为第一节点与第二节点, 第一节 点为直接接收接收节点反馈的接收状态信息的发送节点, 第二节点为不直接 接收接收节点反馈的接收状态信息的发送节点, 即间接的通过第一节点接收 接收节点反馈的接收状态信息的发送节点。 例如, 协同多点 (Coordinative Multiple Point, CoMP) 或者载波聚合 (Carrier Aggregation, CA) 场景中, 地理位置上分离的多个基站, 协同参与一个终端的数据的联合发送或者联合 接收以提升用户的吞吐量。 本实施例中, 与终端建立了上行连接的基站称之 为第一节点, 未与终端建立上行连接的基站称之为第二节点, 针对这些未建 立上行连接的基站的上行数据或者信令, 需要通过其他基站的转发, 其中, 上行连接例如为第一节点与接收节点之间的逻辑信道, 或者为第一节点与接 收节点之间的物理上行共享信道 (Physical Uplink Shared Channel, PUSCH)等。
本步骤中, 接收节点接收第一节点发送的第一数据包与第二节点发送的 第二数据包。 针对第一节点的数据包, 接收节点可直接向第一节点反馈该数 据包接收状态, 针对第二节点的数据包, 接收节点需要将该数据包的接收状 态信息发送给第一节点, 然后再由第一节点将该接收状态信息转发给第二节 点。
102、接收节点对第一数据包生成第一接收状态信息, 接收节点对第二数 据包生成第二接收状态信息。
本步骤中, 针对接收到的第一数据包, 接收节点为其生成反馈该第一数 据包是否成功接收的第一接收状态信息; 针对第二数据包, 接收节点为其生 成反馈该第二数据包是否成功接收的第二接收状态信息。
103、接收节点向第一节点发送携带第一区分标识的第一接收状态信息与 第二接收状态信息, 第一区分标识用于标识第一节点; 或者, 接收节点向第 一节点发送第一接收状态信息与携带第二区分标识的第二接收状态信息, 第 二区分标识用于标识第二节点; 或者, 接收节点向第一节点发送携带第一区 分标识的第一接收状态信息与携带第二区分标识的第二接收状态信息。
接收节点通过与第一节点之间的上行连接, 将第一接收状态信息与第二 接收状态信息都发送给第一节点, 由第一节点向第二节点转发第二接收状态 信息。 可选的, 一对多的网络架构中, 接收节点可不区分第一节点与第二节点 的具体数量, 而是对各第一节点的各第一数据包, 都生成携带第一区分标识 的第一接收状态信息, 同样, 对各第二节点的各第二数据包, 也都生成携带 第二区分标识的第二接收状态信息。 这样, 当接收节点通过上行连接将该些 第一接收状态信息与第二状态信息发送给第一节点后, 第一节点可根据各个 区分标识识别出具体的发送节点, 并进行转发。
可选的, 一对多的网络架构中, 当第一节点有多个、 第二节点有一个的 时候, 接收节点也可以仅对第一节点的第一数据包生成携带第一区分标识的 第一接收状态信息, 而对第一节点的第二数据包生成未携带第二区分标识的 第二接收状态信息, 并通过上行连接将各携带第一区分标识的第一接收状态 信息与不携带第二区分标识的第二接收状态信息发送给第一节点。 这样, 各 第一节点就可以区分出自身数据包的接收状态信息, 而将第二接收状态信息 反馈给第二节点。
可选的, 一对多的网络架构中, 当第一节点有一个、 第二节点有多个的 时候, 接收节点也可以仅对各第二节点的数据包生成携带第二区分标识的第 二接收状态信息, 并通过上行连接将携带第二区分标识的各第二接收状态信 息, 与不携带第一区分标识的第一接收状态信息发送给第一节点。 这样, 第 一节点就可以区分出自身的接收状态信息, 即未携带标识的第一接收状态信 息, 而根据各第二区分标识, 将携带第二区分标识的各第二接收状态信息反 馈给对应的第二节点。
可选的, 一对多的网络架构中, 当第一节点仅有一个、 第二节点也仅有 一个的时候, 接收节点可以选择性的为第一节点或第二节点的数据包生成携 带区分标识的接收状态信息并通过上行连接发送给第一节点。 假设预设的规 则是第一节点的第一接收状态信息携带第一区分标识, 则第一节点保存携带 第一区分标识的第一接收状态信息, 而将未携带标识的第二接收状态信息反 馈给第二节点; 反之, 若预设的规则是第二接收状态信息携带第二区分标识, 则第一节点保存未携带第一区分标识的第一接收状态信息, 而将第二接收状 态信息反馈给第二节点。
本发明实施例提供的数据包接收状态反馈方法, 接收节点通过与第一节 点之间的上行连接, 即同一个逻辑信道将针对第一节点数据包的第一接收状 态信息与针对第二节点数据包的第二接收状态信息发送给第一节点, 由第一 节点根据区分标识将针对各第二节点数据包的第二接收状态信息向各第二节 点转发, 实现一对多的网络架构中, 接收节点能够不受逻辑信道数量的限制 而正确的反馈每一个发送节点的数据包的接收状态的目的。
进一步的, 上述实施例一中, 接收节点根据各第一节点的发送列表, 向 各第一节点发送对应发送列表中的第二节点的第二接收状态信息, 以使各第 一节点向发送列表中的第二节点发送对应的第二接收状态信息, 发送列表保 存对应的第一节点可转发接收状态信息的第二节点的区分标识。
具体的, 当第一节点有多个的时候, 接收节点可选择其中某个第一节点 向各第二节点转发第二接收状态信息。 例如, 一对多的网络架构中, 存在接 收节点 1、 第一节点 Al、 A2、 A3, 第二节点 B1~B9。 若接收节点 1保存的 第一节点 A1的发送列表为 【B1、 B2、 B3 ] , 表示第一节点 A1仅向第二节 点 Bl、 B2、 B3发送接收状态信息; 第一节点 A2的发送列表为 【B4、 B5、 B6】 , 表示第一节点 A2仅向第二节点 B4、 B5、 B6发送接收状态信息; 第 一节点 A3的发送列表为【B7、 B8、 B9], 表示第一节点 A3向第二节点 B7、 B8、 B9发送接收状态信息。 此时, 接收节点 1将针对第一节点 A1的第一接 收状态信息、 第二节点 Bl、 B2、 B3的各第二接收状态信息发送给第一节点 A1 , 由第一节点 A1 向第二节点 Bl、 B2、 B3分别发送其各自所需接收状态 信息。 同理, 接收节点 1将针对第一节点 A2的第一接收状态信息、 第二节 点 B4、 B5、 B6的各第二接收状态信息发送给第一节点 A2, 由第一节点 A2 向第二节点 B4、 B5、 B6分别发送其各自所需接收状态信息; 接收节点 1将 针对第一节点 A3的第一接收状态信息、 第二节点 B7、 B8、 B9的各第二接 收状态信息发送给第一节点 A3, 由第一节点 A3向第二节点 B7、 B8、 B9分 别发送其各自所需接收状态信息。
可选的, 接收节点可以为每个第一节点配置对应的发送列表, 并将发送 列表发送给对应的第一节点; 或者, 各个第一节点在配置好发送列表后, 将 自身的发送列表发送给接收节点和各个第二节点; 或者, 由第二节点配置发 送列表, 并由第二节点向各个第一节点与接收节点发送该发送列表。
进一步的, 上述实施例一中, 接收节点可以为终端、 基站或接入点。 进一步的, 上述实施例一中, 第一区分标识和第二区分标识分别包括小 区标识、 小区序号、 小区所属的群组的标识、 小区所属的群组的序号、 基站 的标识、 承载的标识、 比特串或字符串。
具体的, 若第一节点与第二节点是通过小区发送数据包的, 则各区分标 识可以为小区的标识 /序号, 或者是该小区所属组的标识 /序号; 若第一节点与 第二节点为基站, 则各区分标识可以为对应基站的标识; 若第一节点与第二 节点是通过不同的承载下发数据包的,则各区分标识可以为对应承载的标识。 另外, 也可以预设区分标识, 用任意长度的比特串或字符区分各区分标识。 例如, 当第一节点与第二节点各自的数量仅为 1个时, 将第一区分标识用取 值为 0的比特表示, 将第二区分标识用取值为 1的比特标识; 或者, 当第一 节点的数量为 8个时, 当第二节点的数量为 4个时, 可从取值为 000~111中 任意一个三位比特串表示其中之一的第一节点, 用取值为 00~11中的任意一 个二位比特串表示其中之一的第二节点, 或者, 用整数表示第一节点或第二 节点, 本发明并不以此为限制。
进一步的, 上述实施例一中, 第一节点与第二节点发送的数据包可以是 各种协议的协议数据单元(Protocol Data Unit, PDU) , 其中, 各种协议例如 为分组数据汇聚协议 (Packet Data Convergence Protocol, PDCP) 、 无线链路 控制(Radio Link Control, RLC)协议、媒质接入控制(Medium Access Control, MAC) 协议等, 本发明并不以此为限制。
图 2为本发明数据包接收状态的反馈方法实施例二的流程图。 本实施例 的执行主体为第一节点, 即与接收节点之间存在上行连接的发送节点, 适用 于一对多的网络架构中, 接收节点不受逻辑信道的限制, 需要通过一个发 送节点反馈多个发送节点发送的数据包的接收状态信息的场景。 具体的, 本实施里包括如下步骤:
201、第一节点向接收节点发送第一数据包, 第一节点为直接接收接收节 点反馈的接收状态信息的发送节点, 相应的, 第二节点为不直接接收接收节 点反馈的接收状态信息的发送节点, 第二节点发送的数据包为第二数据包。
有关第一节点、 第二节点等的描述信息请参见图 1实施例一, 此处不再 赘述。
202、第一节点在接收节点为第一数据包生成第一接收状态信息, 并为第 二数据包生成第二接收状态信息后, 接收接收节点发送的携带第一区分标识 的第一接收状态信息与第二接收状态信息,第一区分标识用于标识第一节点, 然后, 向第二节点发送第二接收状态信息。
203、第一节点在接收节点为第一数据包生成第一接收状态信息, 并为第 二数据包生成第二接收状态信息后, 接收接收节点发送的第一接收状态信息 与携带第二区分标识的第二接收状态信息,第二区分标识用于标识第二节点, 然后, 向第二节点发送第二接收状态信息。
204、第一节点在接收节点为第一数据包生成第一接收状态信息, 并为第 二节点的第二数据包生成第二接收状态信息后, 接收接收节点发送的携带第 一区分标识的第一接收状态信息与携带第二区分标识的第二接收状态信息, 然后, 向第二节点发送第二接收状态信息。
上述步骤 202~204中, 第一节点接收接收节点发送的接收状态信息。 具 体的, 可参见上述图 1步骤 103, 此处不再赘述。
需要说明的是, 步骤 202~204仅是针对不同场景的相关描述, 并不代表 执行的先后顺序。
本发明实施例提供的数据包接收状态的反馈方法, 第一节点通过与接收 节点之间的上行连接, 接收针对第一节点数据包的第一接收状态信息与针对 第二节点数据包的第二接收状态信息, 并根据区分标识将第二接收状态信息 向各第二节点转发, 实现一对多的网络架构中, 接收节点能够不受逻辑信道 数量的限制而正确的通过某一个发送节点反馈多个发送节点发送的数据包的 接收状态的目的。
进一步的, 上述实施例二中, 第一节点可以为终端、 基站或接入点。 进一步的, 上述实施例二中, 第一区分标识和第二区分标识分别包括小 区标识、 小区序号、 小区所属的群组的标识、 小区所属的群组的序号、 基站 的标识、 承载的标识、 比特串或字符串。
具体的, 若第一节点与第二节点是通过小区发送数据包的, 则各区分标 识可以为小区的标识 /序号, 或者是该小区所属组的标识 /序号; 若第一节点与 第二节点为基站, 则各区分标识可以为对应基站的标识; 若第一节点与第二 节点是通过不同的承载下发数据包的,则各区分标识可以为对应承载的标识。 另外, 也可以预设区分标识, 用任意长度的比特串或字符区分各区分标识。 例如, 当第一节点与第二节点各自的数量仅为 1个时, 将第一区分标识用取 值为 0的比特表示, 将第二区分标识用取值为 1的比特标识; 或者, 当第一 节点的数量为 8个时, 当第二节点的数量为 4个时, 可从取值为 000~111中 任意一个三位比特串表示其中之一的第一节点, 用取值为 00~11中的任意一 个二位比特串表示其中之一的第二节点, 或者, 用整数表示第一节点或第二 节点, 本发明并不以此为限制。
进一步的, 上述实施例二中, 第一节点与第二节点发送的数据包可以是 各种协议的协议数据单元(Protocol Data Unit, PDU) , 其中, 各种协议例如 为分组数据汇聚协议 (Packet Data Convergence Protocol, PDCP) 、 无线链路 控制(Radio Link Control, RLC)协议、媒质接入控制(Medium Access Control, MAC) 协议等, 本发明并不以此为限制。
图 3为本发明数据包接收状态的反馈方法实施例三的流程图。 本实施例 的执行主体为第二节点, 即与接收节点之间不存在上行连接的发送节点, 适 用于一对多的网络架构中, 接收节点不受逻辑信道的限制, 需要通过某一 个发送节点反馈多个发送节点发送的数据包的接收状态信息的场景。 具体 的, 本实施里包括如下步骤:
301、 第二节点向接收节点发送第二数据包, 第二节点为不直接接收接收 节点反馈的接收状态信息的发送节点, 相应的, 第一节点为直接接收接收节 点反馈的接收状态信息的发送节点, 第一节点发送的数据包为第一数据包。

本步骤中, 在接收到数据包状态信息后, 第二节点根据该数据包状态接 收信息, 确定是否重新发送数据包。 例如, 若第二接收状态信息为正确应答 (Acknowledgement, ACK) , 则意味着数据包成功接收, 无需重新发送数据 包; 否则, 若第二接收状态信息为否定应答 (Negative Acknowledgement, NACK) , 则意味着数据包未能成功接收, 需要重新发送数据包。 本发明实施例提供的数据包接收状态的反馈方法, 第二节点通过接收第 一节点根据区分标识发送的第二接收状态信息并确定是否重新需要发送数据 包, 实现一对多的网络架构中, 接收节点能够不受逻辑信道数量的限制而正 确的反馈每一个发送节点的数据包的接收状态的目的。
