摘要： To prevent connection delay or disconnection.
A wireless base station apparatus (1) has a reporting unit (4) which reports information on a 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 (1). 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 (1). The wireless base station apparatus (1) also has a notifying unit (3) 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 (4) of the handover-destination wireless base station apparatus (1).

摘要： The present invention enables assignment to a terminal a sub-band having satisfactory communication quality.
A reference-signal reception unit (1a) receives from a terminal (2) a reference signal spreading over sub-bands (#1 to #5). A communication-quality measurement unit (1b) measures the communication quality of each of the sub-bands (#1 to #5) on the basis of the reference signal. A sub-band assignment unit (1c) assigns one of the sub-bands (#1 to #5) to the terminal (2) on the basis of the communication quality, for the terminal (2) to perform wireless communication with the communication device (1). A reference-signal transmission unit (2a) transmits to the communication device (1) a reference signal spreading over the sub-bands. A sub-band-assignment-information reception unit (2b) receives information on one of the sub-bands (#1 to #5) which is assigned to the terminal (2) by the communication device (1) on the basis of the reference signal. A data transmission unit (2c) transmits data to the communication device (1) through the sub-band assigned to the terminal (2).

摘要： In an intermittent communication system where an intermittent communication can be made between a base station and a mobile station, a transmitting unit of the mobile station transmits a request to start a normal communication after stopping an intermittent communication at timing different from the intermittent communication if a handover is determined to be required. A transiting unit transits from the intermittent communication to the normal communication after the transmitting unit transmits the request. A handover performing unit performs a handover upon completion of transition to the normal communication by the transiting unit.

摘要： Power consumption by a radio terminal is reduced.
When completing radio communication with a radio terminal (2), a transmitting unit (1a) of a base station (1) transmits to the radio terminal (2) a validity period of control information on radio communication which has been used to communicate with the radio terminal (2). When starting radio communication with the radio terminal (2) within the validity period, a communication unit (1b) performs radio communication with the radio terminal (2) without performing a process of exchanging control information. When completing radio communication with the base station (1), a receiving unit (2a) of the radio terminal (2) receives a validity period from the base station (1). When starting radio communication with the base station (1) within the validity period, a communication unit (2b) performs radio communication with the radio terminal (1) without performing a process of exchanging control information.

摘要： An object is to provide a wireless communication system, a transmitter, a receiving apparatus, and a notification information transmission-reception method that can reduce electrical power consumed when a receiving process is performed on notification information. To realize this object, the transmitter transmits revision history of notification information together with the notification information. Then, when the receiving apparatus is notified that the notification information has been changed or when the receiving apparatus moves between cells, the receiving apparatus receives revision history of the notification information and updates notification information retained in the receiving apparatus on the basis of the received revision history.

摘要： In a mobile communication system according to an embodiment, a mobile relay station configures a common communication restriction period for mobile stations UE under the mobile relay station RN in a period from detection of a handover until when a new backhaul between a target base station and the mobile relay station is applied. Since none of the respective mobile stations under the mobile relay station transmit/receive data during the communication restriction period such as a Measurement gap, a backhaul can be configured within the Measurement gap.

摘要： Wireless communication volume is reduced to improve communication quality.
A wireless communication system (1) includes a relay station (10), first and second wireless base stations (20, 30), a gateway device (40), and a mobile station (2). The gateway device (40) is connected to the first and second wireless base stations (20, 30) by a cable. The first and second wireless base stations (20, 30) are interconnected by a cable. The relay station (10) is connected wirelessly to the first wireless base station (20) to perform relayed communication via the first wireless base station (20). When the mobile station (2) at a lower level than the relay station (10) executes handover to the second wireless base station (30), the first wireless base station (20) switches a data transfer route by redirecting data which is not yet completely transmitted to the mobile station, to be forwarded to the second wireless base station (30).
