摘要： To reduce an uplink interference in a network with a first base station of a large output and a second base station of a small output. Detecting the interference, the second base station urges the first base station to hand over a terminal causing it to the second base station. Multiple base stations and one or more terminals exist in this system, each terminal connects with one base station, and a serving base station is changed according to a communication state of each terminal. If the different second base station other than the first base station to which the terminal connects detects a large interference, the second base station will multicast transmit information for urging handover to the base stations except itself. The base station having received the information specifies a terminal giving the interference to the second base station, and makes it to be handed over thereto.

摘要： In wireless communication systems into which a relay device has been introduced, although terminal reception quality increases, data transmission by relay devices with low contribution causes interference in other data transmission, which invites a decrease in reception quality of electromagnetic waves received by terminals. As a way to resolve the abovementioned issue, as one embodiment of the present disclosures, a wireless relay station is configured so as to receive a plurality of data addressed for wireless terminals from a wireless base station, and to transmit data that are selected from the aforementioned received plurality of data and that are addressed to the aforementioned wireless terminals which are the destinations of transmission. As a result, interference towards other data transmission and reception caused by data transmission of a relay device can be suppressed, and the reception quality of electromagnetic waves received by the terminal can be increased.
