Abstract:
A method for supporting activation/deactivation of serving cells by a base station (eNB) in a wireless communication system provides decreased overhead and decreased power consumption for a user equipment (UE). The method includes configuring M supportable serving cells in the UE, configuring an indicator indicating activation/deactivation of each of the M serving cells, configuring a medium access control (MAC) message which includes a MAC control element (CE) and a logical channel identifier (LCID), the MAC CE including the indicator configured for each of the M serving cells and having a length corresponding to an integer multiple of 8 bits, the LCID indicating that the MAC CE includes the indicator indicating activation/deactivation of each serving cell, and transmitting the configured MAC message to the UE. Accordingly, a control channel or data channel regarding a component carrier is selectively received depending on whether the component carrier is activated.
Abstract:
Hybrid Automatic Retransmit ReQuest-Acknowledgment (HARQ-ACK) index mapping and uplink resource allocation is performed and controlled for channel selection transmission. A method for transmitting HARQ-ACK information to an eNode-B (eNB) by a User Equipment (UE) includes identifying KPCell as a number of downlink subframe(s) of a Pcell associated with an uplink subframe and identifying KSCell as a number of downlink subframe(s) of an Scell associated with the uplink subframe; generating Discontinuous Transmission (DTX) response information for a cell having a smaller number of downlink subframes between the Pcell and the Scell; generating HARQ-ACK information including the generated DTX response information and response information on data received by the UE from the eNB; and transmitting the generated HARQ-ACK information to the eNB through the uplink subframe.
Abstract:
An image saving apparatus may extract an object from a photographed picture, and may store position information. The image saving apparatus may selectively perform image processing of each object using the position information and may provide a user with a dynamic image in which a change in the photograph range is considered.
Abstract:
The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.
Abstract:
A portable terminal and a method for originating a call through a substituted network when originating a call is barred due to overload of a first network is disclosed herein. A call may be originated by automatically switching the communication mode of the portable terminal from the first network such as an LTE network to a second network such as a 3G network or a 2G network, when originating a call is barred in the first network. The information of the cell of the second network is searched from a second network database stored in advance, which allows the time to search for a cell and time to register in the second network decrease. The searched cell with the highest power level may be selected and the call is originated through the selected cell of the second network.
Abstract:
A terminal to hide a message includes an input unit to receive a signal to hide a message and a signal to restore a hidden message; a display unit to display the message and the hidden message; and a control unit to control display of the message. The terminal hides messages or applications on a separate screen. The separate screen may be a virtual screen or a different display screen. A hidden message may be displayed on the separate screen according to a conversation partner. A hidden message may be restored to a location in which the message would have originally been displayed. A portion of the stored message may be extracted and provided to an application of the terminal.
Abstract:
Provided is a method for controlling a plurality of work processes in a multitasking mobile terminal, and more particularly, a method for selecting a second work process during a first work process and controlling a predetermined function of the selected second work process. In the controlling method, icons corresponding to the respective work processes are displayed in response to a user command, and a desired work process is selected through the displayed icons. A predetermined function of the selected work process is controlled through a pop-up menu activated in response to the user command.
Abstract:
The present invention relates to resource allocation in a wireless communication system. Specifically, the method comprises: an encoding step in which a resource block or a resource block group generates a resource indication value (RIV) which is a transform of the length (L) and the offset (j) of a contiguous resource allocation region; and a transmission step in which the resource allocation information is transmitted to a terminal, wherein the resource allocation information is calculated by means of a prescribed mathematical equation.
Abstract:
A method for providing a status of a wireless network, including: receiving a wireless signal from an access point and status information of the access point; determining processing capacity information of the access point based on the status information of the access point; and displaying wireless network information with respect to the access point, the wireless network information including the processing capacity information of the access point and signal strength information of the received wireless signal.
Abstract:
A mobile terminal and control method to share content with a device and control the device are provide. The mobile terminal includes a communication unit to communicate with a host and the device; a search unit to receive content information and device information; an input unit to receive a content selection signal and a device selection signal; and a control unit to control the mobile terminal. The mobile terminal receives content information from a host and selects content to be outputted to a device selected from device information from the host. The mobile terminal controls the selected device using control commands transmitted to the selected device based on a control mode. If the control mode is not stored in the mobile terminal, the mobile terminal may receive the control mode from the host.
