Specifically, a method for transmitting and receiving data in a wireless communication system by a user equipment includes receiving downlink control information from a base station and receiving downlink data from the base station through a downlink shared channel configured based on the downlink control information, wherein when the downlink data is broadcasted, a bundling size for the downlink shared channel is configured as a pre-defined value. ## Claims ### Claim 1 A method for transmitting downlink data in a wireless communication system by a base station, the method comprising: transmitting, to a user equipment, downlink control information, and transmitting, to the user equipment, downlink data through downlink shared channel based on the downlink control information, wherein, based on the downlink data is broadcasted, a bundling size for the downlink shared channel is based on a pre-defined value, wherein, based on the downlink data is not broadcasted, the bundling size is based on a specific number of physical resource blocks or a size of a frequency resource region allocated to the user equipment, and wherein a value representing the specific number of physical resource blocks is included in a bundling size set pre-configured for the downlink shared channel. ### Claim 2 (depends on 1) The method of claim 1, wherein the pre-defined value is based on two physical resource blocks (PRBs). ### Claim 3 (depends on 1) The method of claim 1, wherein, based on the size of the frequency resource region is greater than a value pre-configured for the user equipment, the bundling size is based on the size of the frequency resource region. ### Claim 4 (depends on 3) The method of claim 3, wherein the pre-configured value is configured through higher layer signaling by the base station. ### Claim 5 (depends on 3) The method of claim 3, wherein the frequency resource region is based on contiguous physical resource blocks. ### Claim 6 (depends on 1) The method of claim 1, wherein the pre-configured bundling size set is configured based on the size of the frequency resource region. ### Claim 7 (depends on 2) The method of claim 2, wherein, based on the downlink data is broadcasted, the downlink data comprises a system information block for the user equipment. ### Claim 8 A base station transmitting downlink data in a wireless communication system, comprising: a radio frequency (RF) module for receiving and transmitting radio signals, and a processor functionally connected to the RF module, wherein the processor is configured to: transmit, to a user equipment, downlink control information, and transmit, to the user equipment, downlink data through downlink shared channel based on the downlink control information, and wherein, based on the downlink data is broadcasted, a bundling size for the downlink shared channel is based on a pre-defined value, wherein, based on the downlink data is not broadcasted, the bundling size is based on a specific number of physical resource blocks or a size of a frequency resource region allocated to the user equipment, and wherein a value representing the specific number of physical resource blocks is included in a bundling size set pre-configured for the downlink shared channel. ### Claim 9 (depends on 8) The base station of claim 8, wherein the pre-defined value is based on two physical resource blocks (PRBs). ### Claim 10 (depends on 8) The base station of claim 8, wherein, based on the size of the frequency resource region is greater than a value pre-configured for the user equipment, the bundling size is based on the size of the frequency resource region. ### Claim 11 (depends on 10) The base station of claim 10, wherein the frequency resource region is based on contiguous physical resource blocks.
