Title
(EN) Method and apparatus for packet aggregation in power line communication network
(ZH) 电力线通信网络中的包聚合的方法和设备
Abstract
(EN)
A method and apparatus for packet aggregation in a power line communication network (PLC) are provided. The method of aggregating packets includes: by performing a PLC channel estimation, determining whether or not a channel condition is good; if the channel condition is good, determining whether or not the data desired to be transmitted is suitable for packet aggregation according to the type of data; and if the channel condition is good and the data desired to be transmitted is suitable for the packet aggregation, aggregating packets of the data desired to be transmitted. Since a decision on whether or not to aggregate packets is determined according to a channel condition at a physical level and the type of data at an application level, packet aggregation can be performed in appropriate response to the frequently changing condition of a channel and the characteristic of the data desired to be transmitted. Also, transmission efficiency of the channel can be enhanced and quality of service (QoS) can be guaranteed.

提供一种用于电力线通信(PLC)网络中的包聚合的方法和设备。所述聚合包的方法包括:通过执行PLC信道估计,确定信道条件是否为佳;如果信道条件为佳,则根据数据的类型确定想要发送的数据是否适合于包聚合;如果信道条件为佳并且想要发送的数据适合于包聚合,则聚合想要发送的数据的包。由于关于是否聚合包的决定是根据物理层面的信道条件和应用层面的数据类型而确定的,所以可适当响应于信道的频繁变化条件和想要发送的数据的特性而执行包聚合。此外,可提高信道的发送效率并保证服务质量(QoS)。
