20140194111 | COMMUNICATION SYSTEM, USER TERMINAL, AND COMMUNICATION DEVICE - Disclosed is a technique for starting an application used to receive a message for the application efficiently in order to reduce the processing load on and the battery consumption of a user terminal. According to this technique, a network is requested to transmit a control message to a user terminal when receiving a message addressed to an application on the user terminal, and when receiving, from a server, a message addressed to the application on the user terminal, the network transmits a control message such as paging to the user terminal. The user terminal receives the paging from the network even in the connected mode, and starts an application used to receive a message for the application on the user terminal in response to the reception of the paging so that the application can be started at timing where there exists the message to be received. | 07-10-2014 |
20140328282 | BASE STATION APPARATUS, COMMUNICATION METHOD, TERMINAL APPARATUS AND INTEGRATED CIRCUIT - Provided are a radio terminal device, a radio base station device, and a channel signal forming method which can prevent quality degradation of the downlink source allocation information by reducing the frequency of the zero information addition process to the downlink resource allocation information when executing communication using an uplink unit band and a plurality of downlink unit bands correlated to the uplink unit band. A base station can execute communication using the uplink unit band and a plurality of downlink unit bands correlated to the uplink unit band. The base station includes: a PDCCH generation unit which includes the uplink allocation information relating to the uplink unit band only in some of the channel signals formed for each of the downlink unit bands; and a padding unit which adds zero information to the downlink allocation information only in the selected some channel signals having the bandwidth of the corresponding downlink unit band smaller than that of the uplink unit band until the downlink allocation information size becomes equal to the uplink allocation information size. | 11-06-2014 |
20150078330 | BASE STATION, TERMINAL, BAND ALLOCATION METHOD, AND DOWNLINK DATA COMMUNICATION METHOD - Provided are a base station, a terminal, a band allocation method, and a downlink data communication method in which a mapping method for synchronization signals and report signals is implemented with high resource usage efficiency when a first system in which an independent single communication is allocated to a unit band co-exists with a second system in which a plurality of unit bands can be allocated to a single communication. In a base station, an OFDM signal generation unit maps primary synchronization channel (P-SCH), secondary synchronization channel (S-SCH), primary broadcast channel (P-BCH), and dynamic broadcast channel (D-BCH), which can be decoded by both an LTE terminal and an LTE+ terminal, to some of a plurality of unit bands. The OFDM signal generation unit also maps D-BCH+, which can be decoded only by an LTE+ terminal, to all of the plurality of unit bands to produce a multiplexed transmission signal. | 03-19-2015 |
