AI Technical Summary
Technical Problem
In NR radio communication systems, it is unclear which type of search space a user device should monitor, leading to inefficient monitoring of PDCCH candidates during the random access procedure.
Method used
A user device is configured to monitor a PDCCH candidate in a first search space during a random access procedure and receive PDSCH or transmit PUSCH based on information from the PDCCH, while only using a second search space after the procedure is completed, with defined starting and terminating points for efficient monitoring.
Benefits of technology
This approach allows the user device to identify and efficiently monitor search spaces in the NR system, optimizing resource usage and reducing unnecessary monitoring of PDCCH candidates.
