User equipment and communication method for detection of a control channel in a discontinuous reception cycle

A user equipment, comprising:

• processing circuitry configured to:
• perform a first detection process to attempt to detect a Physical Downlink Control Channel (PDCCH) on a first bandwidth part of an unauthorized frequency band in a detection time of a Discontinuous Reception (DRX) cycle;
• and
• in a case that no PDCCH is detected on the first bandwidth part;
• perform a second detection process to attempt to detect a PDCCH on a second bandwidth part of the unauthorized frequency band;
• determine through a channel detection process that the first bandwidth part is occupied;
• and
• in a case that the first bandwidth part is occupied, detect a PDCCH on the second bandwidth part.

A wireless communication method executed by a user equipment, the wireless communication method comprising:

• performing a first detection process to attempt to detect a Physical Downlink Control Channel (PDCCH) on a first bandwidth part of an unauthorized frequency hand in a detection time of a Discontinuous Reception (DRX) cycle;
• and
• in a case that no PDCCH is detected on the first bandwidth part;
• performing a second detection process to attempt to detect a PDCCH on a second bandwidth part of the unauthorized frequency band;
• in a case that a PDCCH is detected on the second bandwidth part, performing the second detection process to detect a PDCCH on the second bandwidth part in a next DRX cycle of the DRX cycle;
• and
• in a case that no PDCCH is detected on the second bandwidth part, performing the first detection process to detect a PDCCH on the first bandwidth part in a next DRX cycle of the DRX cycle.
