数据传输方法和通信设备

Data transmission method and communication device

Abstract

本发明实施例提供一种数据传输方法和通信设备。该通信设备包括:确定模块,用于执行确定操作,以确定第一空闲信道的个数;发送模块,用于在每个第一空闲信道上向接收端发送数据;判断模块,用于判断是否重新发送该数据;若是,则指示确定模块继续执行确定操作,直至判断发送模块不需要重新发送该数据为止;若否,则指示发送模块不再发送该数据。本发明实施例提供的通信设备,使得数据可以同时在多个第一空闲信道上传输,并且在数据需要重新发送时也可以选择多个第一空闲信道来发送,提高了数据的传输鲁棒性和信道的利用率。
Embodiments of the present invention provide a data transmission method and a communication device. The communication device includes: a determining module used for performing a determination operation to determine the number of first idle channels; a sending module used for sending data to a receiving end over each first idle channel; a judging module used for judging whether to re-send the data, if yes, the determining module is indicated to continue the determination operation until it is judged that the sending module does not need to re-send the data, if no, the sending module is indicated to no longer send the data. with the communication device provided in the embodiment of the present invention, data can be transmitted over several first idle channels at the same time and several first idle channels can be selected to send the data when the data need to be re-sent; therefore the data transmission robustness and channel utilization are enhanced.
