User equipment, base station, and cell reselection method

The base station comprising:

• a communicator configured to transmit, to a communication device, system information relevant for inter-frequency cell reselection, information indicating a duration for the inter-frequency cell reselection, and information indicating a threshold for a received power;
• and
• a controller configured to control for the communication device to perform the inter-frequency cell reselection based on first information and second information included in the system information, the first information indicating a priority of a carrier frequency used for the inter-frequency cell reselection, the second information indicating that a Reduced Capability user equipment is allowed to access, wherein
• the controller is configured to control for the communication device to measure the received power based on CD-SSB (cell-defining SS/PBCH Block) of a cell belonging to the carrier frequency and select, as a suitable cell, the cell belonging to the carrier frequency with the priority higher than a priority of a carrier frequency to which a serving cell belongs, the cell fulfilling a criterion of the received power based on the threshold during the duration.

A communication method performed by a communication device, the communication method comprising:

• receiving, from a base station, system information including information relevant for inter-frequency cell reselection, information indicating a duration for the inter-frequency cell reselection, and information indicating a threshold for a received power;
• and
• performing the inter-frequency cell reselection based on first information and second information included in the system information, the first information indicating a priority of a carrier frequency used for the inter-frequency cell reselection, the second information indicating that a Reduced Capability user equipment is allowed to access, wherein
• in the performing the inter-frequency cell reselection, measuring the received power based on CD-SSB (cell-defining SS/PBCH Block) of a cell belonging to the carrier frequency and selecting, as a suitable cell, the cell belonging to the carrier frequency with the priority higher than a priority of a carrier frequency to which a serving cell belongs, the cell fulfilling a criterion of the received power based on the threshold during the duration.
