Abstract

An embodiment of the present invention provides a detection method and a detection device, which are applied to a narrowband Internet of Things base station, wherein the method includes: receiving an uplink signal from a user equipment; determining the effective power of the signal corresponding to the uplink signal, and determining the effective power of the uplink signal Corresponding signal-to-noise ratio; if the signal-to-noise ratio exceeds a first threshold, or, if the effective power of the signal exceeds a second threshold, determine that the uplink signal includes a random access preamble; the first threshold and / or the second threshold is determined according to the number of repeated transmissions of the random access preamble corresponding to the user equipment. The embodiment of the present invention can reduce the false detection probability and missed detection probability of the Preamble code, improve the accuracy of detecting the Preamble code, and further improve the efficiency of user equipment accessing NB-IoT in high-speed mobile scenarios.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a detection method and a detection device. Background technique [0002] NB-IoT (Narrow Band Internet of Things, Narrowband Internet of Things) is an emerging technology in the field of the Internet of Things. It supports the cellular data connection of low-power devices in the wide area network, and supports the high-efficiency connection of devices with long standby time and high network connection requirements. . [0003] Random access in the NB-IoT system is an important process for establishing a communication link between the user side and the network side. Random access is used between UE (User Equipment, user equipment) and eNodeB (Evolved Node B, evolved base station) To establish uplink synchronization, the performance of random access largely depends on the detection of Preamble (random access preamble). [0004] In practical applications, the base station can...
