Description

数据传输方法及通信设备 技术领域
本发明涉及通信技术领域, 尤其涉及一种数据传输方法及通信设备。 背景技术
随着无线通信***的发展, 上下行数据传输分别使用单载波频分复用多 址 (Single carrier f requency division multiple access, SC-FDMA)和正 交频分复用 (Orthogonal f requency division multiplexing, OFDM)以提高 无线频谱效率。 OFDM ***对频率同步要求高, 性能受频偏和相位噪声影响较 大, 因此在某些场合并不适用, 需要考虑其它多载波调制技术。 同时随着数 据业务的多样化, 对传输也有不同的需求, 如一些机器类通信(Machine type communications , MTC ) 业务周期性发送且数据量较小, 机器对机器 (Machine-To-Machine, M2M )终端设备一般使用年限较长, 因此节能是一个 重要挑战。 为减少信令交互达到节电效果, 更适合采用一些对同步需求不是 很高的物理层传输技术, 如通用滤波器多载波 ( Universal filtered multicarrier , UFMC )、滤波器组多载波( Filter bank multicarrier, FBMC )、 通用频分复用 (Generalized f requency division multi lexing, GFDM ) 、 双正交频分复用 ( Bi-or thogonal f requency division multiplexing, BFDM ) 等, 这些对同步需求不高的物理层传输技术同时还能降低对传输网同步的需 求, 提升协作传输的性能。

在一个具体的例子中, 处理器 120控制 MAC层确定被调度的数据流, 根据被调度的数据流的数据流标识从映射信息中, 确定数据流对应的物理 层传输技术标识, 然后对应相同物理层传输技术的数据流生成同一种传输 块, 对应不同物理层传输技术标识的数据流生成不同的传输块。
具体的, 针对相同物理层传输技术的不同数据流, 可以复用该物理层 传输技术下的通信资源, 例如传输块。 例如图 1A所示, 处理器 120包含控 制器, MAC层调度器, PHY层的多个处理模块(不同物理层传输技术对应不 同的处理模块) 。 其中, 数据流 1, 3, m对应相同的物理层传输技术标识 PHY 1, 可以复用时频资源, 则处理器 120中的控制器控制 MAC层调度器对 应数据流 1, 3, m生成传输块 1; 数据流 2对应物理层传输技术标识 PHY 2, 则处理器 120中的控制器控制 MAC层调度器对应数据流 2生成传输块 2。 然后处理器 120中的 PHY层的 PHY1处理模块利用 PHY1对应的物理层传输 技术对传输块 1进行处理, 生成相应的无线通信数据 1 , 处理器 1 20中的 PHY层的 PHY2处理模块利用 PHY2对应的物理层传输技术对传输块 2进行 处理, 生成相应的无线通信数据 2。

具体的, 针对相同物理层传输技术的不同数据流, 可以复用该物理层传 输技术下的通信资源, 例如传输块。 例如, 数据流 1, 3 , m对应相同的物理层 传输技术标识 PHY 1 , 可以复用, 则发送端的 MAC层对应数据流 1, 3 , m生成 传输块 1 ; 数据流 2对应物理层传输技术标识 PHY 2 , 则发送端的 MAC层对应 数据流 2生成传输块 2。 然后发送端的 PHY层利用 PHY1对应的物理层传输技 术对传输块 1进行处理, 生成相应的无线通信数据 1 , 利用 PHY2对应的物理 层传输技术对传输块 2进行处理, 生成相应的无线通信数据 2。
步骤 S 3 Q5 , 发送端向接收端发送该无线通信数据。

相应的, 步骤 S 402具体为: 根据该下行调度信息携带的物理层传输技术标识确定该无线通信数 据对应的物理层传输技术。
可选地, 当接收端为基站, 发送端为用户设备, 在步骤 S401之前, 该方 法还包括: 接收端为不同的物理层传输技术分配不同的时频资源, 向发送端 发送上行调度信息, 该上行调度信息携带物理层传输技术标识对应的时频资 源信息, 以使发送端确定无线通信数据对应的物理层传输技术对应的时频资 源, 并利用确定的时频资源向该接收端发送无线通信数据。
相应的, 步骤 S402具体为:
根据无线通信数据利用的时频资源确定无线通信数据对应的物理层 传输技术。
由于时频资源是由基站分配的, 因此在接收端为基站的情况下, 基站在 接收到无线通信数据之后, 便可根据该无线通信数据利用的时频资源确定该 无线通信数据在发送端使用的物理层传输技术。
另外, 上行调度信息还可以携带数据流标识与物理层传输技术标识的对 应关系。 则在步骤 S401之前, 该方法还包括: 为数据流分配物理层传输技术。
具体的, 发送端中都存储有数据流标识和物理层传输技术标识的映射 信息。 该映射信息包括: 数据流标识与物理层传输技术标识的对应关系。 其中, 数据流标识可以具体为数据流对应的 LC I D。 物理层传输技术包括: UFMC、 FBMC、 GFDM、 BFDM、 OFDM等。 该映射信息可以为表 1所示的形式, 当然也可以为其他形式, 本发明实施例对此不 任何限制。
其中, 接收端向发送端发送上行调度信息的过程可以具体为: 接收端分 别对多个上行调度信息进行加扰、 信道编码及速率匹配的处理, 将处理后的 各个上行调度信息复用, 生成上行调度信息组, 将该上行调度信息组承载在 下行控制信道上, 发送至发送端; 接收端将多个上行调度信息复用, 生成上 行调度信息组, 对该上行调度信息组进行加扰、 信道编码及速率匹配的处理, 将处理后的上行调度信息组承载在下行控制信道上, 发送至发送端。 步骤 S403 , 接收端根据确定的物理层传输技术对该无线通信数据进行解 析, 得到该无线通信数据对应的传输块。
接收端的 PHY层根据确定的物理层传输技术对无线通信数据进行解析, 得到无线通信数据对应的传输块
步骤 S404,接收端获取该无线通信数据对应的传输块中包括的数据流。 接收端的 MAC层从该无线通信数据解析得到的传输块中获取数据流。 利用本发明实施例四提供的数据传输方法, 若接收端为基站, 则基站可 针对同一用户设备的多个数据流采用不同的物理层传输技术, 若接收端为用 户设备, 则用户设备可对多个数据流采用不同的物理层传输技术, 以充分利 用频谱资源, 从而提高传输效率。
针对前述各实施方式, 具体的, 前述数据流标识和物理层传输技术标识 的映射信息可以由基站建立。 在基站与用户设备建立上行数据连接时, 基站 根据各个小区的业务比例, 为数据流分配物理层传输技术, 从而建立数据流 标识和物理层传输技术标识的映射信息。 基站在建立完该映射信息之后, 通 过将该映射信息携带在配置信息中下发给与该基站连接用户设备。
进一步地, 基站还可以动态更新该映射信息, 基站根据各个小区的业务 比例变化, 为数据流重新分配物理层传输技术, 从而更新数据流标识和物理 层传输技术标识的映射信息。 基站在更新完映射信息之后, 通过将更新后的 数据流标识与物理层传输技术标识的对应关系携带在上行调度信息中发送给 用户设备, 以使用户设备更新存储的映射信息。
如果基站不动态更新映射信息仅使用固定的映射信息, 则在数据流传输 过程中同一数据流只能使用一种物理层传输技术, 不能改变复用方式。 如果 基站可动态更新映射信息, 则在数据流传输过程中同一数据流可使用不同的 物理层传输技术, 相应的, 复用方式也可改变, 便可以更充分利用频谱资源, 从而提高传输效率。
专业人员应该还可以进一步意识到, 结合本文中所公开的实施例描述的 各示例的单元及算法步骤, 能够以电子硬件、 计算机软件或者二者的结合来 实现, 为了清楚地说明硬件和软件的可互换性, 在上述说明中已经按照功能 一般性地描述了各示例的组成及步骤。 这些功能究竟以硬件还是软件方式来 执行, 取决于技术方案的特定应用和设计约束条件。 专业技术人员可以对每 个特定的应用来使用不同方法来实现所描述的功能, 但是这种实现不应认为 超出本发明的范围。
