Abstract

The embodiment of the invention discloses a data transmission method and device and belongs to the field of communication systems. The data transmission method and device can improve the communication efficiency between base stations and communication equipment while the use ratio of communication channels is guaranteed. The transmission method comprises the following steps: firstly, random access lead codes sent by the communication equipment are received by the base stations; secondly, channel conditions corresponding to the random access lead codes or resources occupied by the random access lead codes are acquired by the base stations; finally, communication are conducted by the base stations according to the channel conditions and the communication equipment.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to a data transmission method and device. Background technique [0002] The Internet of Things (M2M, Machine to Machine) is to connect all items to the Internet through information sensing devices to realize intelligent identification and management. With the continuous development of communication equipment, the application of the Internet of Things is becoming more and more extensive, wherein, the communication between the base station and the communication equipment can be realized through the Internet of Things. [0003] At present, when the base station and communication equipment communicate through the Internet of Things, the channel conditions are usually configured to be applicable to all communication equipment in the cell, so as to ensure that communication equipment with poor channel conditions can also communicate with the base station. However, because the channel...
