Abstract: Provided is a method for performing a handover from a first base station to a second base station by a user equipment that is performing a radio communication over a communication channel formed by aggregating a plurality of component carriers. The method includes a step of transmitting a handover command for a component carrier for which a handover has been approved by the second base station among the plurality of component carriers from the first base station to the user equipment and a step of trying to make an access from the user equipment to the second base station for each component carrier in response to the handover command.

Abstract: Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

[Solution] Provided is a communication control apparatus including: a calculation unit configured to calculate a transmit power to be allocated, including a nominal transmit power and a margin for interference avoidance, for one or more secondary systems that secondarily use frequency channels protected for a primary system; and a determination unit configured to determine a variation in a number of secondary systems, and cause the calculation unit to adjust the margin for interference avoidance on a basis of the determined variation.
