[Solution] A communication apparatus including a communication unit configured to perform wireless communication, a control unit configured to control delivery of content for each program using a directional beam, and a notification unit configured to notify a terminal apparatus of first information regarding a timing of transmitting the directional beam in each of a plurality of directions in association with second information notified commonly to one or more of the terminal apparatuses within a communication range. ## Claims ### Claim 1 A communication apparatus comprising: a communication unit configured to perform wireless communication; a control unit configured to control delivery of content for each program using a directional beam; and a notification unit configured to notify a terminal apparatus of first information regarding a timing of transmitting the directional beam in each of a plurality of directions in association with second information notified commonly to one or more of the terminal apparatuses within a communication range. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein the first information includes information regarding a resource allocated depending on the timing. ### Claim 3 (depends on 1) The communication apparatus according to claim 1, wherein the second information is system information. ### Claim 4 (depends on 1) The communication apparatus according to claim 1, wherein the control unit, after notifying the terminal apparatus of the first information, controls in such a way as to execute sweeping of the directional beam to deliver the content corresponding to the program using the directional beam allocated individually for each of one or more of the programs. ### Claim 5 (depends on 4) The communication apparatus according to claim 4, wherein the control unit controls the sweeping of the directional beam individually for each of the programs. ### Claim 6 (depends on 5) The communication apparatus according to claim 5, wherein at least any one of a period of the sweeping, a number of the directional beams transmitted in the sweeping, or a direction of transmission of the directional beam in the sweeping is set for each of the programs. ### Claim 7 (depends on 4) The communication apparatus according to claim 4, wherein the control unit controls in such a way, before executing first sweeping that is the sweeping, as to execute second sweeping of a second directional beam different from a first directional beam that is the directional beam used for delivery of the content for each program, and decides the first directional beam for transmitting the content for each program among a plurality of directional beams to the terminal apparatus on a basis of third information notified in response to a result of receiving the second direction beam from the terminal apparatus. ### Claim 8 (depends on 7) The communication apparatus according to claim 7, wherein the control unit controls the second sweeping to be executed commonly to a plurality of the programs. ### Claim 9 (depends on 7) The communication apparatus according to claim 7, wherein the second sweeping has a period that is set to be equal to or longer than a period of the first sweeping. ### Claim 10 (depends on 7) The communication apparatus according to claim 7, wherein the second directional beams transmitted in the second sweeping are set in numbers to be equal to or larger than the first directional beams transmitted in the first sweeping. ### Claim 11 (depends on 1) The communication apparatus according to claim 1, further comprising: an acquisition unit configured to acquire, from one or more of the terminal apparatuses within the communication range, a request for delivering content for at least a part of one or more of the programs for each of the directional beams used for delivering the content, wherein the notification unit notifies the terminal apparatus of fourth information depending on an acquisition state of the request for each of the directional beams for each of one or more of the programs in association with the second information, and the acquisition unit, after notifying the terminal apparatus of the fourth information, acquires the request from the terminal apparatus. ### Claim 12 A communication apparatus comprising: a communication unit configured to perform wireless communication; an acquisition unit configured to acquire, from a base station, second information associated with first information regarding a timing of transmitting a directional beam used for delivering content for each program in each of a plurality of directions, the second information being notified commonly to one or more terminal apparatuses within a communication range of the base station; and a control unit configured to controls in such a way as to receive the content for each program on a basis of the acquired first information. ### Claim 13 (depends on 12) The communication apparatus according to claim 12, further comprising: a notification unit configured to notify the base station of third information in response to a result of receiving a second directional beam different from a first directional beam transmitted as the directional beam used for delivering the content for each program from the base station, wherein the control unit, after notifying the third information, controls in such a way as to receive the content for each program using the first directional beam. ### Claim 14 (depends on 13) The communication apparatus according to claim 13, wherein the notification unit notifies the base station of the third information in a procedure for establishing communication with the base station. ### Claim 15 (depends on 14) The communication apparatus according to claim 14, wherein the notification unit notifies the base station of the third information corresponding to the first directional beam on a basis of a sequence different for each of the first directional beams. ### Claim 16 (depends on 14) The communication apparatus according to claim 14, wherein the notification unit controls the third information to be notified to the base station within a predetermined window. ### Claim 17 (depends on 16) The communication apparatus according to claim 16, wherein the window is set for each of the first directional beams. ### Claim 18 A communication method executed by a computer, the method comprising: performing wireless communication; controlling delivery of content for each program using a directional beam; and notifying a terminal apparatus of first information regarding a timing of transmitting the directional beam in each of a plurality of directions in association with second information notified commonly to one or more of the terminal apparatuses within a communication range. ### Claim 19 A communication method executed by a computer, the method comprising: performing wireless communication; acquiring, from a base station, second information associated with first information regarding a timing of transmitting a directional beam used for delivering content for each program in each of a plurality of directions, the second information being notified commonly to one or more terminal apparatuses within a communication range of the base station; and controlling in such a way as to receive the content for each program on a basis of the acquired first information. ### Claim 20 A program causing a computer to execute: performing wireless communication; controlling delivery of content for each program using a directional beam; and notifying a terminal apparatus of first information regarding a timing of transmitting the directional beam in each of a plurality of directions in association with second information notified commonly to one or more of the terminal apparatuses within a communication range. ### Claim 21 A program causing a computer to execute: performing wireless communication;
