20090034473 | MOBILE COMMUNICATION SYSTEM USING MOBILE TERMINAL AND HANDOVER CONTROL METHOD - A mobile communication system includes a plurality of base station apparatuses; and a mobile terminal configured to perform HSDPA (High Speed Downlink Packet Access) communication between the mobile terminal and the plurality of base station apparatuses. The mobile terminal has a receiving section configured to receive HS-SCCH (High Speed Shared Control Channel) signals from the base station apparatus as a source of handover and the base station apparatus as a destination of the handover at a same time. | 02-05-2009 |
20100110959 | MOBILE COMMUNICATION SYSTEM, TERMINAL DEVICE, BASE STATION DEVICE AND DATA COMMUNICATION METHOD - A base station transmits multimedia broadcast/multicast service data on the resource block allocated to a multimedia broadcast/multicast service to a number of terminals. The terminal extracts multimedia broadcast/multicast service data from the resource block allocated to the multimedia broadcast/multicast service, which is contained in the signal received from the base station, and measures reception quality of the resource block. The base station transmits auxiliary data on another resource block when the reception quality of the resource block has deteriorated in any of the terminals. The terminal in which the quality of the received data is low to extracts auxiliary data contained in the received signal and synthesizes the data with the multimedia broadcast/multicast service data. | 05-06-2010 |
20100172319 | MOBILE COMMUNICATION METHOD, MOBILE COMMUNICATION SYSTEM, AND MOBILE TERMINAL - A mobile communication method which allows a mobile station and a base station to communicate based on an HSDPA communication mode with a possibility of erroneous base station switching due to erroneous detection of a signal reduced to improve reliability of a mobile communication system, in which, when the mobile station moves from one base station into an area of other base station (S | 07-08-2010 |
20100254305 | MOBILE COMMUNICATION SYSTEM, MOBILE COMMUNICATION TERMINAL, AND MOBILE COMMUNICATION METHOD - In mobile communication between a base station and a mobile station, reception quality is prevented from being degraded even when transmission power supplied from a base station is remarkably changed. A code generated in accordance with an amount of change in transmission power is transmitted from the base station to the mobile station. In the mobile station, the code generated by the base station is detected by a detector ( | 10-07-2010 |
20100290556 | RADIO SIGNAL TRANSMISSION DEVICE, RADIO SIGNAL TRANSMISSION METHOD, RADIO SIGNAL RECEPTION DEVICE, RADIO SIGNAL RECEPTION METHOD, AND RADIO SIGNAL RECEPTION PROGRAM - To provide a radio signal reception device which can reduce a process delay and reduce a buffering capacity and a power consumption. Specifically, the radio signal reception device includes: a demapping unit which extracts a sub frame from a received radio signal, judges whether a first OFDM symbol existing at the head of the sub frame and forming a control channel contains information on a signal destined to a reception device contained in a data channel, and if yes, outputs a plurality of OFDM symbols; and a decoding unit which decodes the OFDM symbols which has been outputted from the demapping unit. If the first OFDM symbol contains no information on the signal destined to the reception device, the demapping unit terminates the sub frame reception processing. | 11-18-2010 |
