Description

上下行分离的通信处理方法、 装置及系统
技术领域 本发明实施例涉及通信技术,尤其涉及一种上下行分离的通信处理方法、 装置及系统。 背景技术
随着移动业务的不断发展, 用户对数据速率的要求也越来越高, 为了提 升用户设备 ( User Equipment, 以下简称 UE ) 的数据传输速率, 一些技术点 已经开始考虑基站间的协作服务, 例如基站间多点协作传输 (Inter-eNB Coordinated Mutiple Points , 以下简称 Inter-eNB CoMP )技术、 基站间载波聚 合 ( Inter-eNB Carrier Aggregation, 以下简称 Inter-eNB CA )技术、 基站间多 流架构 ( Inter-eNB Multiple Streamimg Architecture,以下简称 Inter-eNB MSA ) 技术、 异构网络( Heterogeneous Network , 以下简称 HetNet ) 、 小小区增强 ( Small Cell enhancement )技术等,都是釆用多个基站为同一个 UE进行服务。
目前移动通信中的一个重要课题是小小区增强, 小小区增强和宏网络同 时部署是其中的一个场景, 在这种场景下, 小小区可以和宏基站一同为 UE 服务, UE的上行业务通过小基站(Pico )来服务, 下行业务可以通过宏基站 ( Macro eNB ) 来服务, 这种通信架构即为上下行分离架构。

S711 : 第二通信节点向第一通信节点发送该下行数据传输反馈信息。 具体的, 第二通信节点在计算出的资源位置上接收到 UE发送的下行 数据传输反馈信息之后, 将 UE的下行数据传输反馈信息通过 X2接口发 送给第一通信节点, 该 X2接口为第一通信节点与第二通信节点之间的接 口, 可以是有线接口, 也可以是无线接口。 更具体的, 第二通信节点通过 X2接口向第一通信节点发送 UE的下行数据传输反馈信息,可以为第二通 信节点将检测到的 UE 的包含下行数据传输反馈信息的信号发送给第一通 信节点, 该信号可以是物理层信号或者基带信号, 也可以为第二通信节点 根据 PUCCH的配置参数解调获取下行数据传输反馈信息, 并将该下行数据 传输反馈信息发送给第一通信节点。 该 PUCCH的配置参数包括但不限于下 面几种: PUCCH在哪些 TTI会与 SRS碰撞、 PUCCH上反馈信息占用的 PRB总数、 PUCCH上反馈资源的间隔、第一通信节点的 PCI、 PUCCH DM RS 配置参数、 下行数据传输反馈信息的资源编号, 其中 PUCCH在哪些 TTI会与 SRS碰撞具体为: SRS由 UE发送, 便于第一通信节点或第二通 信节点通过接收 SRS来获知无线信道信息,若 PUCCH与 SRS刚好在同一 个 TTI被发送, 则两者发生碰撞, 此时需要发送截短的 PUCCH; PUCCH 上反馈资源的间隔 ,该参数由第一通信节点配置,表示可用于传输 PUCCH 上反馈的间隔资源, 通常该值越大, 反馈的传输性能越好, 但资源利用率 越低; PUCCH DM RS配置参数, 可以是 CS跳变参数, 即在不同 TTI中 或不同符号中, PUCCH的序列所使用的正交码资源(即 CS的取值)是不 同的, 即是 CS跳变; 具体 CS在不同符号或 TTI中的取值是受到 CS跳变 参数控制的, UE根据该跳变参数即可确定在对应符号或 TTI中所使用的 CS的取值, 因 UE会使用该 CS值来生成 PUCCH, 所以第一通信节点向 第二通信节点发送该参数, 便于第二通信节点根据该 CS值检测 UE发送 的 PUCCH。 则第二通信节点根据第一通信节点发送的上述参数中的一种 或者几种就可解析出 PUCCH上的下行数据传输反馈信息, 进而通过第一 通信节点与第二通信节点之间的接口将该反馈信息发送给第一通信节点 (该接口可以为 X2接口, S1接口, 或者 X3接口) , 使得第一通信节点 获知 UE接收下行数据的通信是否完整可靠。
另外, 上述 PUCCH的配置参数都可以通过新增的 X2 AP或 X3 AP、 下行 HARQ反馈接收请求消息、上行传输请求消息等来传输,也可以通过 在已有消息中新增信息的方式来发送,该新增消息可以包括切换消息, UE 上下文建立消息, 承载建立消息等消息。
S712: 第一通信节点接收第二通信节点发送的下行数据传输反馈信息。 具体的, 第二通信节点在上述计算得到的上行资源上接收 UE发送的 下行数据传输反馈信息, 进而将该下行数据传输反馈信息通过第一通信节 点与第二通信节点之间的接口发送给第一通信节点 (该接口可以为 X2接 口, S1接口, 或者 X3接口) , 以使第一通信节点获知 UE与第一通信节 点之间通信是否完整可靠。
本实施例提供的方法中, 通过第一通信节点向第二通信节点发送相关 参数和小区专用的配置参数, 使得第二通信节点根据相关参数接收第一通 信节点发送的下行数据调度信息, 之后, 第二通信节点根据接收到的小区 专用的配置参数以及下行数据调度信息确定接收 UE发送的下行数据传输 反馈信息的上行资源位置, 并在该上行资源位置上接收下行数据传输反馈 信息, 使得第一通信节点通过接收的反馈信息获知 UE与第一通信节点之 间的通信是否完整, 从而提高了通信的可靠性, 同时, UE接收第一通信 节点的下行数据, 将下行数据对应的下行数据传输反馈信息由第二通信节 点转发给第一通信节点, 降低了 UE的功耗, 并且避免了现有技术中 UE 通过增大自身的发射功率向第一通信节点发送下行数据传输反馈信息而 给邻近的小区带来干扰的问题, 且 UE无需更改频率来发上行信息, 并且当 时间提前量不同时, 也无需调整发射时间, 从而降低了 UE设备的复杂度。

S801 : 第一通信节点与第二通信节点协商, 预留部分第二通信节点的上 行资源。 具体的, 第一通信节点与第二通信节点协商, 预留部分第二通信节点的 上行资源, 用于后续的第一通信节点给 UE调度上行传输, 该预留第二通信 节点的上行资源的方式可以是: 通过与第二通信节点之间的接口与第二通信 节点进行协商交互, 预留第二通信节点的上行资源; 也可以是通过 OAM, 预留第二通信节点的上行资源。
S802: 第一通信节点在预留的上行资源上向第二通信节点发送上行数据 调度信息。

本实施例提供的方法中, 通过 UE和第二通信节点接收第一通信节点发 送的上行数据调度信息, UE在该调度信息指示的上行资源上发送上行数据给 第二通信节点, 之后第二通信节点将该上行数据对应的上行数据传输反馈信 息通过 Χ2接口发送给第一通信节点, 由第一通信节点转发给 UE, 使得 UE 获知 UE与第二通信节点之间的通信是否完整可靠,避免了 UE若在第二通信 节点覆盖的范围之外, 因第二通信节点的发送功率较低而使得 UE有时接收 不到第二通信节点发送的上行数据传输反馈信息的情况发生, 提高了通信的 可靠性, 且 UE无需更改频率来发上行信息, 并且当时间提前量不同时, 也 无需调整发射时间, 从而降低了 UE设备的复杂度。
