The UE receives downlink control information from a base station. The downlink control information includes an indicator for configuring the bundling size of a downlink shared channel. The UE receives downlink data from the base station through a downlink shared channel configured based on the downlink control information. The bundling size may be configured based on a value of the indicator. ## Claims ### Claim 1 A method of receiving data by a user terminal in a wireless communication system, the method comprising: receiving, from a base station, configuration information related to a physical resource block (PRB) bundling size of a downlink shared channel, wherein the configuration information comprises a bundling size set consisting of two values among a plurality of candidate values; receiving, from the base station, downlink control information comprising a bundling size indicator; based on the bundling size indicator having a specific indicator value, determining the PRB bundling size as one of the two values in the bundling size set, based on whether a size of contiguous scheduled PRBs in a frequency domain exceeds a threshold that is related to a size of a bandwidth part (BWP) for the user terminal; and receiving downlink data from the base station through the downlink shared channel configured based on the PRB bundling size. ### Claim 2 (depends on 1) The method of claim 1, wherein the plurality of candidate values is equal to {2, 4, W}, where W represents the size of the contiguous scheduled PRBs in the frequency domain. ### Claim 3 (depends on 1) The method of claim 1, wherein the specific indicator value is “1”. ### Claim 4 (depends on 1) The method of claim 1, wherein the two values in the bundling size set are equal to either {2, W} or {4, W}, where W represents the size of the contiguous scheduled PRBs in the frequency domain. ### Claim 5 (depends on 1) The method of claim 1, wherein determining the PRB bundling size as the one of the two values in the bundling size set based on whether the size of contiguous scheduled PRBs in the frequency domain exceeds the threshold comprises: based on the size of the contiguous scheduled PRBs being greater than the threshold, determining the PRB bundling size as a greater value among the two values in the bundling size set. ### Claim 6 (depends on 1) The method of claim 1, wherein determining the PRB bundling size as the one of the two values in the bundling size set based on whether the size of contiguous scheduled PRBs in the frequency domain exceeds the threshold comprises: based on the size of the contiguous scheduled PRBs being smaller than the threshold, determining the PRB bundling size as a smaller value among the two values in the bundling size set. ### Claim 7 (depends on 1) The method of claim 1, wherein the threshold that is related to the size of the BWP for the user terminal is equal to the size of the BWP divided by 2. ### Claim 8 A user terminal configured to receive data in a wireless communication system, the user terminal comprising: a radio frequency (RF) module; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising: receiving, from a base station, configuration information related to a physical resource block (PRB) bundling size of a downlink shared channel, wherein the configuration information comprises a bundling size set consisting of two values among a plurality of candidate values;
