摘要： To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information.

摘要： The present invention provides a radio communication system, apparatus, and method that allow said optimal setting to be determined from a viewpoint of a PTP system throughput of an MBSFN area while satisfying an MBSFN quality requirement condition. Transmission parameters, such as MCS of MBSFN, the number of MBSFN subframes, and a transmission power in a reserved cell, are adaptively output, based on a unicast traffic volume in a MBSFN area, the number of terminals, and the number of cells in the MBSFN area, so that a system throughput in the MBSFN area is maximized while satisfying an MBSFN quality requirement condition.

摘要： A method for controlling uplink radio resource which can improve the capacity and coverage of a mobile communication network includes the steps of: measuring, at base stations, both total interference and intra-cell interference values; reporting measured values to a radio network controller; calculating, at the radio network controller, allowed total interference for individual cells in response to the reporting from the base stations; sending information about the allowed total interference to the base stations; and scheduling, in response to the allowed total interference by the base stations, uplink data packet transmission of mobile stations not to exceed the allowed total interference calculated for the respective cells.

摘要： It is possible to solve the problem that a downstream control information amount is significantly increased if allocation information is periodically reported because no allocation method of a default E-DCH resource configuration is defined for a preamble signature. A base station and a mobile station decide a default resource configuration by using a total number of resource configurations or a value obtained from the total number.

摘要： The present invention provides a DRX control method and system in which power consumption of a mobile station can be reduced and an increase in the load of a network can be suppressed. A source base station forwards Dormancy Context, which is information for controlling the activity level of a mobile station that performs inter base station handover, to a target base station and, immediately after the mobile station completes handover, the target base station performs DRX control of the mobile station using the Dormancy Context.
