Abstract: A method of a wearable device displaying icons is provided. The method includes displaying a plurality of circular icons comprising a first circular icon located in a center area of a touch display in a first size and a second circular icon located outside of the center area of the touch display in a second size smaller than the first size, and based on a direction of a touch input received on the touch display, moving the plurality of circular icons such that the first circular icon is moved to a first position located outside of the center area of the touch display and the second circular icon is moved from a second position located outside the center area of the touch display to the center area of the touch display and enlarged in size from the second size to the first size.

Abstract: A data receiving device may include a dummy stage block. The dummy stage block may include m dummy stages, wherein m is a natural number greater than or equal to two. Each of the m dummy stages may be configured to remove inter-symbol interference (ISI) from a dummy input signal using dummy coefficient information to generate a dummy output signal free of the ISI. Each of the m dummy stages may be further configured to output the dummy output signal. A normal stage block may include n normal stages, wherein n is a natural number greater than or equal to two. Each of the n normal stages may be configured to remove ISI from an input signal using coefficient information to generate an output signal free of the ISI and may be further configured to output the output signal.

Abstract: A method and apparatus for transmitting and receiving downlink control information in a mobile communication system supporting an uplink packet data service are provided. To transmit packet data in an HARQ mobile communication system, a second transceiver receives an RG as rate control information from a first transceiver. The second transceiver sets the allowed maximum data rate of an HARQ process to which the RG is applied to the allowed maximum data rate of an HARQ process previous to the HARQ process, if the RG indicates hold. The second transceiver transmits packet data within the set allowed maximum data rate to the first transceiver.

Abstract: A method and apparatus for transmitting/receiving scheduling channels in a wireless communication system supporting spectrum scalability are provided, in which scheduling bandwidth of a User Element (UE) is determined, scheduling information including index information indicating resources allocated to the UE, transport format information about data to be transmitted to the UE, and Hybrid Automatic Repeat reQuest (HARQ) information is configured if a scheduling bandwidth of the UE is equal to a system bandwidth, the scheduling information is divided into first scheduling information and second scheduling information, and each of the first scheduling information and the second scheduling information is mapped to scheduling resources corresponding to a frequency band adjacent to a center frequency of the system bandwidth and having a bandwidth equal to a minimum bandwidth of the UE, and transmitted to the UE.

Abstract: A method and an apparatus for reporting a buffer status of a buffer storing packet data to be transmitted by a user equipment for a scheduling assignment of an uplink packet data service in a mobile communication system supporting the uplink packet data service are disclosed. A user equipment stores packet data having a priority corresponding to a plurality of priority queues having inherent priorities and relating to at least one service, and transmits buffer status information containing queue identifiers of the priority queues and buffer payload information representing an amount of the packet data stored in the priority queues. Herein, the user equipment inserts the buffer status information into a header part of a protocol data unit for the uplink packet data service, inserts the packet data into a payload part of the protocol data unit, and then transmits the protocol data unit.
