Abstract

This application relates to a method, device, computer equipment and storage medium for determining the number of ports. The terminal device first determines the initial number of transmission ports of the NPBCH signal according to the first port power and the second port power of the NPBCH signal, and then passes the initial The number of transmission ports and the SNR of the first port NRS carry out secondary confirmation on the initial number of transmission ports to obtain the number of target transmission ports. In this way, by making an initial judgment on the NRS-related physical quantities of the NPBCH signal, and then verifying the initial judgment result, avoiding Directly demodulate and decode the NPBCH single and dual ports to determine the number of transmission ports, thereby greatly reducing the complexity of the operation of the port number determination process and shortening the processing time.

Description

technical field [0001] The present application relates to the technical field of narrowband Internet of Things, in particular to a method, device, computer equipment and storage medium for determining the number of ports. Background technique [0002] Narrow Band Internet of Things (NB-IoT for short) is an emerging technology in the field of the Internet of Things. It is built on a cellular network and supports the cellular data connection of low-power devices in a wide area network. It is also called a low-power wide area network ( LPWAN), due to its wide coverage, multiple connections, fast speed, low cost, low power consumption, and excellent architecture, is widely used in a variety of vertical industries, such as remote meter reading, asset tracking, smart parking, smart agriculture, etc. [0003] The NB-IoT system is the same as the Long Term Evolution (LTE) system. When the terminal interprets the physical broadcast channel (PBCH) to obtain information, it needs to co...
