摘要： Radio communication apparatus perform communication by using a plurality of frequency bands. The radio communication apparatus transmits to the radio communication apparatus by using a first frequency band a control message including identification information indicating a second frequency band different from the first frequency band during a random access procedure. The radio communication apparatus receives the control message from the radio communication apparatus by using the first frequency band and performs data communication by using the second frequency band indicated by the identification information included in the control message.

摘要： A radio communication apparatus specifies a radio resource area in which a radio communication apparatus searches for a control signal, on the basis of information about the use of a plurality of frequency bands. Then, the radio communication apparatus transmits a control signal addressed to the radio communication apparatus in the specified radio resource area. The radio communication apparatus calculates the specified radio resource area on the basis of the information about the use of the plurality of frequency bands. Then, the radio communication apparatus searches signals in the calculated radio resource area, out of signals received from the radio communication apparatus, and thereby detects the control signal addressed to the radio communication apparatus.

摘要： A backhaul is configured in such a manner that a HARQ process in which a HARQ on an upstream access link is incapable of being partly or entirely performed is limited to a particular one of a plurality of HARQ processes. As a result, complexity of scheduling is reduced and efficiency of the access link is improved.

摘要： A radio environment acquirer acquires a radio environment condition of radio communication with a subordinate mobile station. A transmitter transmits, to the mobile station, information notifying a signal which is selected from among multiple signal groups and which is to be transmitted in a transmission area of a random access signal, and a notification of a period over which transmission of the signal as the random access signal is permitted. The period is variable in accordance with the radio environment condition acquired by the radio environment acquirer.

摘要： A wireless base station apparatus includes a reporting unit which reports information on a first transmission area that allows transmission of a random access signal. Accordingly, the first transmission area is wholly reported to mobile station apparatuses within an area of the wireless base station apparatus. That is, both a mobile station apparatus in a non-handover state and a mobile station apparatus in a handover state receive the first transmission area information (report information) and use the first transmission area as a transmission area for transmitting a random access signal to the wireless base station apparatus. The wireless base station apparatus also has a notifying unit which notifies a second transmission area to a mobile station apparatus in a handover state, the second transmission area being different from the first transmission area reported by the reporting unit of the handover-destination wireless base station apparatus.
