Abstract:
An electronic device is provided. The electronic device includes an output unit, a storage unit, an antenna, a sensor, and a controller. The output unit outputs a video or voice. The storage unit stores information about a user interface operation. The antenna transmits/receives a wireless signal of a corresponding communication frequency band and is moveable. The sensor acquires information of at least one motion of the antenna. The controller processes a wireless signal through the antenna and outputs the user interface operation according to the information received from the sensor, to the output unit with reference to the information of the storage unit.
Abstract:
A method of operating a terminal that is related to achieving synchronization in a wireless communication system is provided. The method includes receiving signals with a bandwidth comprising a plurality of channels, selecting at least one channel group to attempt to detect based on radio frequency level per a reception signal, wherein the channel group denotes a set of channels that belongs to one bandwidth, and performing a synchronization procedure on each of channels that belong to the at least one channel group selected.
Abstract:
An apparatus and a method for transmitting HARQ feedback information in a wireless communication system are provided. In so doing, the method for transmitting the HARQ feedback information in a receiving end includes confirming the number of packets received from a transmitting end, and when receiving a reference number of packets from the transmitting end, transmitting to the transmitting end a feedback signal comprising HARQ feedback information for the reference number of the packets.
