Abstract: Provided are a method and an apparatus for transmitting a scheduling request in a wireless communication system. Particularly, a terminal receives, from a base station, allocation information for an SR resource and allocation information for an SPS resource. The terminal transmits a scheduling request through the SR resource or the SPS resource. The allocation information for the SR resource indicates that the SR resource is allocated to a first period. The allocation information for the SPS resource indicates that the SPS resource is allocated to a second period. When the scheduling request is transmitted through the SPS resource, the scheduling request is not transmitted through a predetermined plurality of subframes including the SPS resource.

Abstract: The present application provides a method for allocating resources in a wireless communication system using multiple antennas. The method for allocating resources comprising: transmitting a reference signal to first-type terminals based on type information of a plurality of terminals; receiving channel estimation information from the first-type terminals that have received the reference signal; generating beams based on the received channel estimation information; and allocating resources for the generated beams. First-type beams for the first-type terminals are primarily generated and allocated, and on the basis of the generated first-type beams, second-type beams for second-type terminals may be non-orthogonally generated and allocated when the resources for the beams are allocated.
