Abstract: An access point for assigning a radio resource to a radio communication apparatus based on admission control, the access point including: a state determination unit configured to determine whether there is a first radio communication apparatus that is in a sleep state by a power saving function; and an assignment unit configured to temporarily assign a radio resource assigned to the first radio communication apparatus to a second radio communication apparatus when the state determination unit determines that there is the first radio communication apparatus.

Abstract: A wireless communication apparatus transmits a packet that includes a destination address, a source address, and a frame body over a wireless network. The wireless communication apparatus computes a first calculation value for use in detecting packet falsification based on a destination address, a source address, and a frame body by using a predetermined computation method, and stores the first calculation value that is associated with the destination address. When a second packet is to be transmitted to a same destination address that is the same as the destination address stored in the storage unit, the wireless communication apparatus computes a second calculation value using the first calculation value stored in the storage unit and the frame body contained in the second packet by using the predetermined computation method.

Abstract: A radio communications apparatus having multiple radio equipment units is disclosed. The radio communications apparatus includes a radio equipment selecting unit which selects one of the radio equipment units based on a received quality in each of the radio equipment units when transferring to a power saving state; and a radio equipment control unit which operates the radio equipment unit selected by the radio equipment selecting unit and stops a radio equipment unit other than the selected radio equipment unit.
