Abstract

A communication apparatus that performs wireless communication by directional communication includes a detection unit that detects a change in a position of the communication apparatus, and a control unit that controls changing a communication direction for performing the directional communication between the communication apparatus and another communication apparatus based on the detected change in the position of the communication apparatus.

First claim

What is claimed is:

1 . A communication apparatus that performs wireless communication by directional communication, the communication apparatus comprising:
a detection unit configured to detect a change in a position of the communication apparatus; and a control unit configured to control changing a communication direction for performing the directional communication between the communication apparatus and another communication apparatus based on the detected change in the position of the communication apparatus.

2 . The communication apparatus according to claim 1 ,
wherein the detection unit further detects a change in an orientation of the communication apparatus, and wherein the control unit controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus based on the detected change in the orientation and the detected change in the position of the communication apparatus.

3 . The communication apparatus according to claim 1 ,
wherein the control unit acquires a relative position between the communication apparatus and the another communication apparatus based on the detected change in the position of the communication apparatus, and wherein the control unit controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus based on the acquired relative position between the communication apparatus and the another communication apparatus.

4 . The communication apparatus according to claim 3 , wherein the acquired relative position includes a change in a position of the another communication apparatus.

5 . The communication apparatus according to claim 1 , wherein the control unit acquires a direction and a change amount of a relative change between the communication apparatus and the another communication apparatus based on the detected change in position of the communication apparatus, and
wherein the control unit controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus based on the acquired direction and the acquired change amount of the relative change.

6 . The communication apparatus according to claim 1 ,
wherein the control unit maps a relative position of the another communication apparatus to the communication apparatus based on the detected change in position of the communication apparatus, and wherein the control unit controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus such that the communication direction for performing the directional communication matches a direction toward the mapped position of the another communication apparatus.

7 . The communication apparatus according to claim 1 , wherein the control unit acquires an amount of the change in the position of the communication apparatus based on the detected change in position, and, in a case where the acquired amount of the change exceeds a predetermined threshold value, controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus or searching for the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus.

8 . The communication apparatus according to claim 7 , wherein, in a case where the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus is searched for, the control unit controls updating relative position information between the communication apparatus and the another communication apparatus based on the searched communication direction.

9 . The communication apparatus according to claim 1 , wherein the control unit acquires an amount of a relative change between the communication apparatus and the another communication apparatus based on the detected change in position of the communication apparatus, and, in a case where the acquired amount of the change exceeds a predetermined threshold value, controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus or searching for the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus.

10 . The communication apparatus according to claim 1 , wherein the control unit acquires evaluation information of the communication when the directional communication is performed between the communication apparatus and the another communication apparatus, and, in a case where the acquired evaluation information falls below a predetermined threshold value, controls changing the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus or searching for the communication direction for performing the directional communication between the communication apparatus and the another communication apparatus.

11 . The communication apparatus according to claim 10 , wherein the control unit acquires the evaluation information of the communication when the directional communication is performed between the communication apparatus and the another communication apparatus by receiving evaluation information evaluated by the another communication apparatus or receiving and evaluating a signal transmitted from the another communication apparatus.

12 . The communication apparatus according to claim 1 , wherein, in a case where there is a change in a relative position between the communication apparatus and the another communication apparatus, the control unit controls increasing a signal width of the directional communication along a direction of the change in the relative position.

13 . The communication apparatus according to claim 12 , wherein the control unit controls increasing the signal width of the directional communication based on an amount of the change in the relative position between the communication apparatus and the another communication apparatus.

14 . The communication apparatus according to claim 12 , wherein the control unit controls increasing the signal width of the directional communication based on a relative speed between the communication apparatus and the another communication apparatus.

15 . The communication apparatus according to claim 12 , wherein, in a case where the signal width of the directional communication is changed, the control unit controls the communication direction of the directional communication such that the another communication apparatus is located at a substantially central position of the signal width.

16 . The communication apparatus according to claim 1 , wherein the control unit performs control such that a signal width of the directional communication is reduced as a distance to the another communication apparatus increases and the signal width of the directional communication is increased as the distance to the another communication apparatus decreases.

17 . The communication apparatus according to claim 1 , wherein the control unit increases a signal width of the directional communication based on a change in a relative position
