- the terminal device In the New Radio (NR, New Radio, also known as 5G) system, in order to obtain downlink data, the terminal device needs to monitor the Physical Downlink Control Channel (PDCCH) to determine whether there is downlink scheduling information.
- the process of monitoring the PDCCH is: the terminal device decodes the PDCCH, and then through the cyclic redundancy check (CRC, Cyclic Redundancy Check) check to determine whether it is the downlink control information (DCI, Downlink Control Information) carrying the terminal device scheduling information .
- CRC Cyclic Redundancy Check
- the base station allocates one or more search spaces to users through system messages, and the configuration of each search space is periodic, and the terminal device performs PDCCH detection in the configured search space.
