Method for downlink channel reception in wireless communication system and device therefor

Abstract

The present invention provides a method for downlink channel reception by a terminal in a wireless communication system and a device therefor. Specifically, a method for downlink channel reception by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, beam configuration information relating to a plurality of transmission beams of the base station; receiving, from the base station, beam indication information indicating one or more transmission beams among the plurality of transmission beams of the base station; and receiving a downlink control channel through a specific transmission beam among the one or more transmission beams, on the basis of the received beam configuration information and the received beam indication information.

What is claimed is: 
     
         1 . A method of receiving, by a terminal, a physical downlink control channel (PDCCH) in a wireless communication system, the method comprising:
 receiving, from a base station (BS), configuration information related to a plurality of beams through a Radio Resource Control (RRC) signaling,   wherein the plurality of beams are configured for each resource region for monitoring the PDCCH;   receiving, from the BS, beam information through a physical channel, the beam information related to a specific beam among the plurality of beams, and   receiving the PDCCH through the specific beam in a resource region.   
     
     
         2 . The method of  claim 1 , wherein the monitoring the PDCCH in the resource region comprises performing blind decoding for the PDCCH in the resource region. 
     
     
         3 . The method of  claim 1 , wherein the resource region is configured as at least one of a time resource and/or a frequency resource. 
     
     
         4 . The method of  claim 1 , wherein the specific beam is indicated through a specific preamble or a specific physical channel received in a symbol prior to a symbol in which the PDCCH is received. 
     
     
         5 . The method of  claim 1 , further comprising:
 reporting, to the BS, information for one or more beams of the plurality of beams, by performing beam measurement on the plurality of beams.   
     
     
         6 . The method of  claim 5 , wherein the information for the one or more beams further comprises information for one or more reception beams of the terminal corresponding to the one or more beams. 
     
     
         7 . The method of  claim 1 , wherein the configuration information and the beam information are received through higher layer signaling. 
     
     
         8 . The method of  claim 1 , wherein the beam information is received through a medium access control-control element (MAC-CE). 
     
     
         9 . The method of  claim 1 , wherein a bit size for the plurality of beams is determined based on a time unit in which downlink control information of the PDCCH is capable of being transmitted. 
     
     
         10 . The method of  claim 1 ,
 wherein the resource region is one of a plurality of resource regions related to the terminal, and   wherein the plurality of resource regions is divided based on a unit of monitoring the PDCCH.   
     
     
         11 . A terminal receiving a physical downlink control channel (PDCCH) in a wireless communication system, the terminal comprising:
 at least one transceiver configured to transmit and receive radio signals, and   at least one processor functionally connected to the at least one transceiver,   wherein the at least one processor is configured to:
 receive, from a base station (BS), configuration information related to a plurality of beams for the PDCCH through a Radio Resource Control (RRC) signaling, 
 wherein the plurality of beams are configured for each resource region for monitoring the PDCCH, 
 receive, from the BS, beam information through a physical channel, the information related to a specific beam among the plurality of beams, and 
 receive the PDCCH through the specific beam in a resource region. 
   
     
     
         12 . The terminal of  claim 11 , wherein the resource region is a resource region monitored, by the terminal, for the PDCCH. 
     
     
         13 . The terminal of  claim 11 ,
 wherein the resource region is one of a plurality of resource regions related to the terminal, and   wherein the plurality of resource regions is divided based on a unit of monitoring the PDCCH.
