Abstract

The embodiment of the invention provides a communication method and device of the cellular internet of things. The method is applied to an evolution base station, and the evolution base station is connected with user equipment; a wireless frame is sent to the user equipment, wherein a target location is arranged in the wireless frame, the target location is used for carrying an indication signal of the user equipment, and the indication signal represents that the control information of the user equipment is existent in the wireless frame. A user equipment terminal can detect whether the indication signal of the user equipment is provided at the target location in the wireless frame, and then decides to perform the blind detection or end this detection to continuously detect the target location of the next wireless frame; therefore, the blind detection is avoided when the control information of the user equipment is inexistent.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a communication method for the cellular Internet of Things and a communication device for the cellular Internet of Things. Background technique [0002] LTE (Long Term Evolution) is the long-term evolution of the mobile communication system technical standard formulated by 3GPP. The LTE system is divided into two network elements, EPC (Evolved Packet Core, evolved packet core network) and eNodeB (Evolved Node B, evolved base station). Its main evolution goal is to achieve a better user experience with high data rate and low latency. [0003] With the development of mobile technology and the increase in business requirements of the Internet of Things, such as smart meter reading, environmental monitoring and other application scenarios, the LTE system also needs to meet the communication requirements of UE (User Equipment, User Equipment) of the Internet of Things...
