Abstract

The embodiment of the invention provides a detection method and a detection device which are applied to a narrowband Internet of Things base station, and the method comprises the following steps: receiving an uplink signal from user equipment; determining signal effective power corresponding to the uplink signal and a signal-to-noise ratio corresponding to the uplink signal; and if the signal-to-noise ratio exceeds a first threshold, or if the effective power of the signal exceeds a second threshold, determining that the uplink signal comprises a random access lead code. The first threshold and / or the second threshold are / is determined according to the repeated sending times of the random access preamble corresponding to the user equipment. According to the embodiment of the invention, thefalse detection probability and the missing detection probability of the Preamble code can be reduced, the accuracy of detecting the Preamble code is improved, and the efficiency of accessing the NB-IoT by the user equipment in a scene of high-speed movement can be further improved.

Description

Technical field [0001] The present 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, Narrow Band Internet of Things) is an emerging technology in the field of Internet of Things, which supports the cellular data connection of low-power devices on the WAN, and supports the efficient 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) 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 accurately detect the Preamble code...
