A UE detects a physical downlink control channel, PDCCH, on a configured control resource set; the UE analyzes the detected PDCCH, and determines a method for dividing code blocks, CBs, and a method for rate matching of a physical downlink shared channel, PDSCH, and receives the PDSCH accordingly. By the method of the present application, when a service with a low delay requirement punches the time-frequency resources of other services, a performance of the other services is improved as much as possible, and the resource utilization rate is improved as much as possible. ## Claims ### Claim 1 A method of a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, a physical downlink shared channel (PDSCH) based on a physical downlink control channel (PDCCH) including a downlink control information (DCI) format;
