  • Patent number: 9161368
    Abstract: A communication terminal adjusts the transmission timing of data transmitted to a base station so that the base station can receive the data within a predetermined delay time. The communication terminal includes a reception section 701 for receiving priority of MAC control information transmitted from the base station, a priority control section 703 for defining the relationship between the priority of the MAC control information and priority assigned to DRB and SRB, and a transmission message generation section 704 for controlling so as to transmit information having a high priority early in accordance with the relationship between the priorities defined by the priority control section 703. According to the communication terminal, a comparison is made between the priority of the MAC control information and the priority assigned to the DRB and the SRB, whereby it is made possible to control what information is to be transmitted as desired.

  • Publication number: 20150271845
    Abstract: A method and transmission apparatus transmit broadcast system information in a mobile communication system. Further, a method and mobile terminal receive the broadcast system information. An improved method for broadcasting broadcast system information maps different partitions of broadcast system information to a shared transport channel or a broadcast transport channel for transmission. The mapping may take into account parameters inherent to the mobile terminals to which the broadcast system information is to be transmitted and/or parameters inherent to the different partitions of broadcast system information.

  • Patent number: 9143461
    Abstract: Disclosed is a technique for enabling a device that needs to send high priority and high bandwidth user plane traffic to send the user plane traffic even in the case where a group bandwidth has an upper limit in group-based communication. According to the technique, when an MTC device that is to send high priority and high bandwidth user plane traffic sends a service request to a network node (P-GW 213a), the network node allows use of a minimum bandwidth bearer in the case where the upper limit of the group bandwidth is exceeded. The MTC device sends a traffic sending request to an MTC server 214a via the bearer. The MTC server stops traffic of an appropriate other MTC device, to secure a bandwidth for the MTC device having the high priority and high bandwidth user plane traffic.

  • Publication number: 20150189675
    Abstract: The invention relates to methods for adjusting the transmit power utilized by a mobile terminal for uplink transmissions, and to methods for adjusting the transmit power used by a mobile terminal for one or more RACH procedures. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for adjusting the transmit power of uplink transmissions on uplink component carriers, the invention suggests introducing a power scaling for uplink PRACH transmissions performing RACH procedures on an uplink component carrier. The power scaling is proposed on the basis of a prioritization among multiple uplink transmissions or on the basis of the uplink component carriers on which RACH procedures are performed.

  • Publication number: 20150156688
    Abstract: A terminal apparatus (1) which is a radio transmitting/receiving apparatus receives, from a femto cell base station (home eNB), a pilot channel signal for reception quality measurement and a synchronization channel signal for synchronization. The terminal apparatus (1) has a whitelist stored therein indicative of an accessible femto cell, and determines whether or not a CSG cell of handover destination is accessible based on a PCI of the CSG cell acquired from the synchronization channel and the whitelist. The terminal apparatus (1) then adds the PCI and a CGI to a measurement report for reception quality, and transmits the measurement report to a macro eNB (base station apparatus (2)). In this way, it is possible to suppress wasteful signaling and prevent unnecessary resources from being reserved even when two or more CSG cells that use the same PCI are present in the macro cell.

  • Patent number: 9049705
    Abstract: 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.

  • Publication number: 20150117342
    Abstract: The invention relates to methods for improving a scheduling request transmission between a UE and a base station. The transmission of the scheduling request is postponed, by implementing a threshold that the data in the transmission buffer has to reach, before a transmission of the scheduling request is triggered. In one variant, the data in the transmission buffer needs to reach a specific amount, to trigger a scheduling request. The invention refers to further improvements: the PDDCH monitoring time window is delayed after sending a scheduling request; the dedicated scheduling request resources of the PUCCH are prioritized differently such that low-priority scheduling requests are transmitted less often.

  • Patent number: 8989739
    Abstract: A technique is disclosed for preventing a mobile terminal from unnecessarily connecting to a local connection service provided by a mobile router. In a communication system, a UE 10 sends user preference information to a forwarding node 20 before the UE connects to the forwarding node, which is installed in a moving body 110 as an access point of the UE to forward information to the UE. The forwarding node determines whether information capable of being supplied to the UE is appropriate for a user of the UE based on the preference information and sends the determination result to the UE. When the UE becomes connectable to the forwarding node, the UE does not connect to the forwarding node if the information capable of being supplied is not appropriate for the user of the UE based on the determination result; else the UE connects to the forwarding node.

  • Patent number: 8971270
    Abstract: The invention relates to a method for paging a group of MTC devices, and for transmitting parameter information to the MTC devices using the paging mechanism. MTC devices are grouped together and a different group ID per group to which the MTC device belongs is assigned to the MTC device. A specific group paging resource indication is determined for each group wherein each MTC device is assigned one of the group paging resource indications. The network pages MTC devices of a group by transmitting a paging message at the corresponding channel resources and including the corresponding group ID. Additionally, the group paging resource indications of several groups of MTC devices can be aligned in such a way with the transmissions and re-transmissions by the network, that the different groups respectively receive the transmission and re-transmissions of the paging message.
