Problems solved by technology

Since the 3G / LTE / WiMAX system is mainly oriented to mobile communication scenarios with wide area coverage, its system features are not optimized for medium and short-distance wireless communication scenarios
At the same time, based on the relatively complex upper-layer protocol design of 3G / LTE / WiMAX and the strict requirements on synchronization at the PHY layer, the equipment cost cannot be as low as 802.11. This is one of the important reasons why Femto technology has not been widely used so far.

Abstract

The invention provides a data transmission method and a data transmission device, comprising a data transmitting method, a data receiving method, a data transmitting device and a data receiving device. The data transmitting method comprises the following steps of: packaging a media access control protocol data unit (MPDU) into a subframe of a group media access control protocol data unit (G-MPDU), wherein the step comprises the following process of: setting a delimiter in front of the MPDU, wherein the delimiter is composed of the delimiter identifier and the length checking information of the MPDU; packaging one or more sub-frames into the G-MPDU; and transmitting the G-MPDU.

Description

[0001] This application claims that the filing date is February 7, 2012, the application number is 201210026596.3, and the title of the invention is a data transmission method and device.
