Communication method using frequency band of base station in wireless communication system, and device using method

Abstract

Provided are a communication method using a frequency band of a base station in a wireless communication system, and a device using the method. The method divides an entire frequency band so as to determine a plurality of subbands and transmits a transport block in at least one subband among the plurality of subbands, wherein the size of the transport block has a maximum value set so as to correspond to the entire frequency band size or the subband size.

         14 . A communication method in a wireless communication system, the method performed by a user equipment (UE) and comprising:
 receiving configuration information, wherein the configuration information indicates the UE of at least one bandwidth part (BWP) which is configured to the UE; and   receiving a transport block on the at least one BWP,   wherein each of the at least one BWP is a part of an entire frequency band,   wherein a maximum size of the transport block is configured based on a size of a BWP among the at least one BWP, where the transport block is allocated to the BWP, and   wherein based on the transport block being related to a reference signal, a sequence of the reference signal is applied after being generated based on the entire frequency band and after being divided into a size corresponding to the transport block on the BWP.   
     
     
         15 . The method of  claim 14 , wherein at least one of a synchronization signal and system information is transmitted on the transport block. 
     
     
         16 . The method of  claim 14 , wherein the transport block corresponding to a number of the at least one BWP is scheduled based on the maximum size of the transport block. 
     
     
         17 . The method of  claim 14 , wherein at least one of channel state information (CSI) measurement, radio resource management (RRM) measurement, and sounding reference signal (SRS) transmission is performed for each of the at least one BWP. 
     
     
         18 . The method of  claim 14 , wherein a control frequency band, at which scheduling information is transmitted, is designated only within a specific BWP or designated for each BWP among the at least one BWP. 
     
     
         19 . A user equipment (UE) comprising:
 a transceiver configured to transmit and receive a radio signal; and   a processor operatively coupled with the transceiver and configured to:   receive configuration information, wherein the configuration information indicates the UE of at least one bandwidth part (BWP) which is configured to the UE; and   receive a transport block on the at least one BWP,   wherein each of the at least one BWP is a part of an entire frequency band,   wherein a maximum size of the transport block is configured based on a size of a BWP among the at least one BWP, where the transport block is allocated to the BWP, and   wherein based on the transport block being related to a reference signal, a sequence of the reference signal is applied after being generated based on the entire frequency band and after being divided into a size corresponding to the transport block on the BWP.   
     
     
         20 . The UE of  claim 19 , wherein at least one of a synchronization signal and system information is transmitted on the transport block. 
     
     
         21 . The UE of  claim 19 , wherein the transport block corresponding to a number of the at least one BWP is scheduled based on the maximum size of the transport block. 
     
     
         22 . The UE of  claim 19 , wherein at least one of channel state information (CSI) measurement, radio resource management (RRM) measurement, and sounding reference signal (SRS) transmission is performed for each of the at least one BWP. 
     
     
         23 . The UE of  claim 19 , wherein a control frequency band, at which scheduling information is transmitted, is designated only within a specific BWP or designated for each BWP among the at least one BWP.
