Radio communication apparatus and radio communication method

A radio communication apparatus performing radio communication based on either role, a master or a slave, the radio communication apparatus comprising:

• a role change receiver receiving a role change request to change from a master to a slave when the radio communication apparatus has a role of master and has established connection to another radio communication apparatus operating as a slave;
• and
• an identification information transmitter transmitting identification information to the other radio communication apparatus on a given channel,
• wherein, in response to the role change receiver receiving the role change request, the identification information transmitter transmits, in order to establish reconnection to the other radio communication apparatus, the identification information at time intervals shorter than time intervals at which the identification information transmitter transmits the identification information when the role change receiver does not receive the role change request.
