An apparatus and a method for generating a frame for communication using beamforming in a wireless communication system are provided. A method for transmitting a signal in a transmitting stage includes determining a beam change time of a region for transmitting information in a frame, and transmitting the information to a receiving stage over the region for transmitting the information by considering the beam change time. The frame includes a plurality of regions divided based on a type of the information transmitted to the receiving stage, and the plurality of the regions includes different beam change times.

Apparatus and method for beamforming in wireless communication system

A system and a method minimize power consumption, signalling overhead, and processing load in blind scheduling in a mobile communication system. A User Equipment (UE) detects a type of an uplink (UL) grant while it is periodically allocated the UL grant. If there is no data to transmit using the UL grant, the UE determines whether to transmit a padding Medium Access Control (MAC) Protocol Data Unit (PDU) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) using the UL grant according to the type of the UL grant.
