1. A communication apparatus comprising:
- a power saving unit configured to cause a wireless communication section to transition to a power saving state and an awake state periodically;
a communication unit configured to execute wireless communication by a prescribed protocol periodically; and
a changing unit configured to change, in accordance with execution timing at which wireless communication by the prescribed protocol is executed periodically and transition timing at which the wireless communication section is caused to transition from the power saving state to the awake state, either the execution timing or the transition timing before wireless communication by the prescribed protocol is executed periodically.

Abstract
If periodic processing in a higher-layer protocol control unit occurs in a case where a wireless LAN control unit is in a power saving mode, there is a high probability that the higher-layer protocol control unit will time out and that communication will be severed. Accordingly, the present invention arranges it so that respective timer values are changed dynamically in such a manner that periodic processing in the higher-layer protocol control unit and a sleep state in the power saving mode will not conflict with each other.
