摘要:
A method used in a radio communication system including a first radio base station, a second radio base station that communicates with the first radio base station, a relay station which communicates with the second radio base station via the first radio base station, and a mobile station, the method transmits a request, by the second radio base station, for requesting the first radio base station to communicate with the relay station for the second radio base station and communicating, by the requested first radio base station, with the relay station for the second radio base station and transmits a communication result to the second radio base station.
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:
A wireless communication system includes a relay station, first and second wireless base stations, a gateway device, and a mobile station. The gateway device is connected to the first and second wireless base stations by a cable. The first and second wireless base stations are interconnected by a cable. The relay station is connected wirelessly to the first wireless base station to perform relayed communication via the first wireless base station. When the mobile station at a lower level than the relay station executes handover to the second wireless base station, the first wireless base station 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.
摘要:
A relay station, that relays wireless communication between a wireless base station and a mobile terminal, includes a processor that detects a connection state of a first link between the wireless base station and the relay station in a wireless communication area, and controls a transmission of a signal using a second link between the mobile terminal and the relay station according to the state of the first link.
摘要:
A wireless communication system includes a base station, a user equipment, and a relay station that relays a wireless signal sent and received between the base station and the user equipment. The relay station includes a first processor that executes reconnection processing with the base station, every time a plurality of time durations with respect to certain timing elapse, for a call corresponding to each time duration, and a transmitter that, if a reconnection with the base station is not made until a predetermined time elapses after a start of the reconnection processing for the call corresponding to the each time duration, sends a message for notifying a call disconnection of the corresponding call in response to the lapse of the predetermined time. The user equipment includes a receiver, and a second processor that executes call disconnection processing on the corresponding call in response to the message being received.
摘要:
An MBMS-GW delivers multicast data from a contents management server respectively to base stations, partitions and codes the multicast data into a plurality of pieces of multiple description code data, and delivers the plurality of pieces of MD-code data respectively to the base stations. Each of the base stations arbitrarily sets a plurality of transmission carrier frequencies for respectively transmitting the plurality of pieces of MD code data, and concurrently transmits the plurality of pieces of MD code data delivered from the MBMS-GW by respectively using the plurality of transmission carrier frequencies set by the transmission frequency setting unit. An LTE terminal or an LTE-A terminal receives, from a corresponding base station, any one or more of the plurality of pieces of MD code data transmitted by using the plurality of transmission carrier frequencies, and decodes and reproduces the multicast data from the received MD-code data.
