摘要： A communication duration configuring method is used in a mobile communication system including a mobile relay station for relaying a wireless communication between a base station and a mobile station. The method includes: configuring at least any of a downlink communication duration where the relay station receives a transmission signal from the base station by restricting a transmission of a signal from the relay station to the mobile station and an uplink communication duration where the relay station transmits a transmission signal to the base station by restricting a transmission of a signal from the mobile station to the relay station; and restricting a transmission of a signal with the mobile station in a first period from detection of a handover until when the communication duration is configured between the relay station and a target base station, and using a desired duration within the first period.

摘要： A radio communication system includes a relay station, a first radio base station, second radio base stations, and a mobile station. The relay station is connected by radio to the first radio base station and communicates with the second radio base stations via the first radio base station. When the relay station communicates with the second radio base stations, the relay station requests the first radio base station to communicate with the second radio base stations for the relay station. The requested first radio base station communicates with the second radio base stations for the relay station and transmits a communication result to the relay station.

摘要： In transmission in which MIMO is applied, there have been problems that the number of variable parameters increases and the number of information bits necessary for control channel increases. When the number of simultaneous multiplex users in one frame increases, there is also a problem of increased control channel information in proportion to the number of users. Error correction coding is performed for the control channel information based on the Adaptive Modulation and Coding scheme, and the above error correction coded control channel information is transmitted after being modulated with a predetermined modulation scheme, and further, according to propagation condition, the coding rate in the above error correction coding is made variable.

摘要： A technique for improving the efficiency of downloading transmission data is disclosed. An information downloading apparatus downloads differing sets of information to predetermined groups to which a mobile terminal may belong. This apparatus includes a channel selecting unit for selecting from plural information channels an information channel for transmitting transmission data and a transmitting unit for transmitting transmission data using the selected information channel. The channel selecting unit selects an information channel so that sets of transmission data with differing destination addresses may be transmitted through differing information channels. The transmitting unit transmits to each group, through a control channel, information pertaining to whether a set of transmission data exists, the information channel to be used if the set of transmission data exists, and the data length of the set of transmission data. The control channel includes time slots that are associated with the groups.

摘要： A handover control method in a mobile communication system that performs handover control by switching base stations that communicate with a mobile terminal as the mobile terminal moves. In this handover control method, a mobile control device selects one or more handover base station candidates based on the communication state, and based on the communication capabilities of the handover base station candidates, decides a transmission rate for multicasting communication data, and transmits communication data to each of the handover base station candidates at the decided transmission rate, and a handover base station candidate that is decided as a handover base station sends the saved multicast communication data to the mobile terminal.
