More particularly, disclosed are a method for transmitting and receiving a signal by a base station or a terminal by means of applying a beam-forming method which varies for each predetermined resource region, and a device supporting same.

1 . A method of transmitting an uplink signal by a user equipment (UE) in a wireless communication system, the method comprising:
 transmitting the uplink signal by applying a different beamforming scheme to each of resource areas divided according to a predetermined rule in one or more symbols of a slot including a plurality of symbols.   
     
     
         2 . The method according to  claim 1 , wherein the uplink signal is a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). 
     
     
         3 . The method according to  claim 1 , wherein the application of a different beamforming scheme to each of resource areas divided according to the predetermined rule comprises applying one or more of digital beamforming, analog beamforming, and hybrid beamforming differently to each of the resources areas divided according to the predetermined rule. 
     
     
         4 . The method according to  claim 1 , wherein when the uplink signal is transmitted in one symbol, the uplink signal is transmitted by applying a different beamforming scheme to each of the frequency areas divided according to the predetermined rule in the one symbol. 
     
     
         5 . The method according to  claim 4 , further comprising receiving information on the predetermined rule from a base station. 
     
     
         6 . The method according to  claim 5 , wherein the information on the predetermined rule includes one of information about the size of frequency resources to which the same beamforming scheme is applied, and information on a range of frequency resources to which the same beamforming scheme is applied. 
     
     
         7 . The method according to  claim 4 , wherein when the uplink signal is mapped distributedly in the frequency domain within one symbol, the predetermined rule indicates division of resource areas in which a different beamforming scheme is applied to each set of contiguous frequency resources or each set of contiguous resources of the same comb index in the one symbol carrying the uplink signal. 
     
     
         8 . The method according to  claim 1 , wherein when the uplink signal is transmitted in two symbols, the predetermined rule indicates division of resource areas in which a different beamforming scheme is applied to each symbol carrying the uplink signal. 
     
     
         9 . The method according to  claim 1 , wherein when the uplink signal is transmitted in two symbols, the predetermined rule indicates division of resource areas in which a different beamforming scheme is applied to each frequency resource area of a predetermined size in the two symbols. 
     
     
         10 . The method according to  claim 1 , wherein the two symbols include a symbol including a reference signal (RS) and a symbol without an RS. 
     
     
         11 . The method according to  claim 1 , wherein when the uplink signal is transmitted in more than two symbols, the predetermined rule indicates division of resources areas in which a different beamforming scheme is applied to each of a plurality of symbol groups into which the symbols carrying the uplink signals are grouped, and
 wherein each symbol group includes at least one symbol including an RS.   
     
     
         12 . The method according to  claim 1 , wherein if the uplink signal is transmitted by frequency hopping in more than two symbols, the predetermined rule indicates division of resource areas in which a different beamforming scheme is applied to each hop in the more than two symbols. 
     
     
         13 . A user equipment (UE) for transmitting an uplink signal to a base station (BS) in a wireless communication system, the UE comprising:
 a transmitter;   a receiver; and   a processor operatively connected to the transmitter and the receiver,   wherein the processor is configured to transmit the uplink signal by applying a different beamforming scheme to each of resource areas divided according to a predetermined rule in one or more symbols of a slot including a plurality of symbols.
