The control unit selects, from a plurality of slot configurations and/or a plurality of symbol configurations, a configuration of a slot and/or a symbol to be used for communication with another communication device. The control unit communicates with the other communication device using the selected slot configuration and/or the selected symbol configuration. ## Claims ### Claim 1 A communication device comprising a control unit that selects, from a plurality of slot configurations and/or a plurality of symbol configurations, a configuration of a slot and/or a symbol to be used for communication with another communication device and communicates with the other communication device using the selected slot configuration and/or the selected symbol configuration. ### Claim 2 (depends on 1) The communication device according to claim 1, wherein the plurality of slot configurations and/or the plurality of symbol configurations are configurations in which numbers of symbols per slot are respectively different. ### Claim 3 (depends on 1) The communication device according to claim 1, wherein numerologies of the plurality of slot configurations and/or the plurality of symbol configurations are same. ### Claim 4 (depends on 1) The communication device according to claim 1, wherein the plurality of slot configurations and/or the plurality of symbol configurations have same subcarrier spacing and/or cyclic prefix. ### Claim 5 (depends on 1) The communication device according to claim 1, wherein the plurality of slot configurations and/or the plurality of symbol configurations respectively have different start positions of the slot. ### Claim 6 (depends on 1) The communication device according to claim 1, wherein the plurality of slot configurations and/or the plurality of symbol configurations respectively have different symbol lengths. ### Claim 7 (depends on 1) The communication device according to claim 1, wherein the control unit notifies the other communication device of selection information concerning the selected slot configuration and/or the selected symbol configuration. ### Claim 8 (depends on 7) The communication device according to claim 7, wherein the selection information is included in system information and/or dedicated RRC signaling and provided in notification. ### Claim 9 (depends on 7) The communication device according to claim 7, wherein notification of the selection information is provided by using an SSB. ### Claim 10 (depends on 9) The communication device according to claim 9, wherein the control unit provides notification of the selection information according to a period of the SSB or transmission timing of the SSB. ### Claim 11 (depends on 1) The communication device according to claim 1, wherein each of the plurality of slot configurations and/or the plurality of symbol configurations are correlated with at least one of a BWP, a configured grant, an SPS, a C-DRX, a traffic type, a priority level, a cell, a communication link, and a physical channel. ### Claim 12 (depends on 1) The communication device according to claim 1, wherein the slot configuration and/or the symbol configuration is switched according to the communication. ### Claim 13 (depends on 1) The communication device according to claim 1, wherein the control unit selects, based on notification from the other communication device, a configuration of at least one of the slot and the symbol to be used for the communication. ### Claim 14 (depends on 1) The communication device according to claim 1, wherein the control unit notifies the other communication device of configuration information concerning the plurality of slot configurations and/or the plurality of symbol configurations. ### Claim 15 (depends on 1) The communication device according to claim 1, wherein the control unit acquires, from the other communication device, selection information concerning a configuration of the slot and/or the symbol to be used for the communication and selects, based on the acquired selection information, a configuration of the slot and/or the symbol to be used for the communication. ### Claim 16 A communication method comprising: selecting, from a plurality of slot configurations and/or a plurality of symbol configurations, a configuration of a slot and/or a symbol to be used for communication with another communication device; and communicating with the other communication device using the selected slot configuration and/or the selected symbol configuration. ### Claim 17 A communication system comprising a first communication device and a second communication device, wherein the first communication device includes a control unit that selects, from a plurality of slot configurations and/or a plurality of symbol configurations, a configuration of a slot and/or a symbol to be used for communication with the second communication device and communicates with the second communication device using the selected slot configuration and/or the selected symbol configuration, and the second communication device includes a control unit that acquires selection information concerning the slot configuration and/or the symbol configuration selected by the first communication device and communicates with the first communication device using the acquired slot configuration and/or the acquired symbol configuration.
