Abstract: A communication apparatus comprises: a communicator configured to receive, from a base station, a radio resource control (RRC) message including information configuring a skipping duration during which monitoring of a physical downlink control channel (PDCCH) is skipped, and to receive, from the base station and through the PDCCH, downlink control information (DCI) including an information field related to the monitoring of the PDCCH; and a controller configured to control, based on a value set in the information field, skipping of the monitoring of the PDCCH over the skipping duration. The controller is configured to perform control so as not to execute the skipping of the monitoring of the PDCCH while a timer is in operation, the timer being related to retransmission for a discontinuous reception (DRX) operation.

Abstract: A wireless communication device uses multiple wireless communication services for communication between an in-vehicle device of a vehicle and an external device. The wireless communication device acquires a delay characteristic value for each wireless communication service from a network device. The delay characteristic value is an upper limit of an estimated range of delay time in communication. The wireless communication device acquires an allowable delay amount indicating a length of an allowable communication delay time from the in-vehicle device. The wireless communication device allocates a wireless communication service, which is relatively small in the delay characteristic value among the wireless communication services, to the in-vehicle device that is small in the allowable delay amount.

Abstract: A communication technology for communication between at least one application and an external device uses subscriber identification modules that correspond, respectively, to wireless communication services. In the technology, first information for determination of a transmission power value is acquired for each of the wireless communication services. In the technology, second information for determination of a delay time allowed by the at least one application is acquired. In the technology, a wireless communication service is selected from among the wireless communication services for the communication based on the first information and the second information.

Abstract: A user equipment 100 to which a plurality of cell groups are configured by a base station 200, comprises the steps of: receiving a switching instruction for giving an instruction about switching of search space set groups (SSSGs) in serving cells belonging to any cell group of the plurality of cell groups from the base station 200; specifying a target cell group as a switching target of the SSSG from among the plurality of cell groups based on a cell identifier or a cell group identifier included in the switching instruction. The UE 100 is configured to simultaneously switch the SSSGs of all the serving cells in the specified target cell group in response to the reception of the switching instruction.

Abstract: Each of a first communication device and a second communication device is capable of performing vehicle-to-vehicle communication and cellular communication. The first communication device issues a proxy request to the second communication device for communication with an application server. When the second communication device receives proxy communication, the second communication device acquires an unused port number from the first communication device, notifies a relay server of the port number as the number of the port for proxy communication, and then performs the proxy communication.
