摘要:
A radio communication system capable of, in a case where a base station device is movable, easily estimating the location of a base station device and easily estimating the location of a user equipment device using the estimation results, and also provide a user equipment device, a base station device, and a management device included in the radio communication system. In addition to an E-SMLC for UE for use in location estimation of a target UE, an E-SMLC for eNB for use in location estimation of an eNB is provided. The E-SMLC for eNB estimates location information of an eNB in an E-UTRAN and performs a process, such as the management of moving of a target eNode B_s and a target eNode B_uu based on the estimated location information.
摘要:
A mobile communication system capable of performing communication between a user equipment device connected to a relay device and a core network if the relay device moves. An RN sets a TA of an eNB to be connected with the own device as a TA of the own device. For example, when the RN moves along an arrow, the TA of the RN is changed from a first TA to which a fourth eNB belongs to a third TA to which a tenth eNB belongs. Upon change of the TA of the RN as described above, a user equipment device transmits a TA update request signal of the own device to a target second MME.
摘要:
A communication system improving the communication quality in a case where a plurality of communication devices having different sizes of ranges coexist, in which communication with a terminal device is possible, to thereby improve an entire throughput. In a case where a remote radio head (RRH) is installed in a coverage of a macro cell, an uplink resource transmitted from a user equipment (UE) to the macro cell, that is, an uplink carrier frequency band UL1 of the macro cell is received not only by the macro cell but also by the RRH. Then, the macro cell combines a reception signal regarding the uplink resource of the macro cell, which has been received by the macro cell, and a reception signal regarding the uplink resource of the macro cell, which has been received by the RRH.
摘要:
A mobile communications system including a mobile terminal 1 and a base station 2 which relays communications between a network and the mobile terminal 1, in which the base station 2 can deliver information to the mobile terminal 1 by using an MBMS, in which the base station 2 sets a flag indicating presence or absence of emergency information to a control channel used for the MBMS, and notifies the presence or absence of the emergency information to the mobile terminal 1 by using the description of the flag set to the control channel for the MBMS.

A radio network controller 3 is so constructed as to divide a plurality of base stations 2 into a group of base stations included in an E-DCH active set and a group of base stations included in an active set for soft handovers (i.e., a prior art active set) according to a status of reception of data in each of the plurality of base stations 2.
摘要:
For lack of a unique, specific and detailed specification for information on status of a mobile station to be notified by a mobile station to a fixed station, an operation may be varied from one mobile station to another in a communication system, thereby posing a problem for an efficient uplink scheduling. A communication method includes a transmission process multiplexing a transport channel for transmitting data from a high-order layer on a physical data channel and transmitting the multiplexed result to the fixed station, a status notification process notifying status information containing information on a transmission power headroom used for scheduling, and a transmission control process receiving the scheduling result and controlling the transmission process. The status information notification process includes notifying an index attached to each predetermined transmission power headroom level classified between upper and lower limit values of the transmission power headroom as the status information.
