Abstract: A method of receiving a Physical Downlink Shared Channel (PDSCH) includes: receiving, in a first bandwidth part (BWP), a downlink control information (DCI) including (i) first information that indicates switching an active BWP from the first BWP to a second BWP, and (ii) second information related to scheduling at least one transport block (TB) for the PDSCH; and receiving, in the second BWP, the PDSCH based on the first information and the second information. Based on a number of TBs in a first group of TBs that can be scheduled through the second information being equal to one, and based on a number of TBs in a second group of TBs that can be scheduled for the second BWP being equal to two: among the second information related to scheduling the at least one TB, information related to a second TB among the second group of TBs is disabled.

Abstract: A user equipment attempts to decode decoding candidates and detects a physical downlink control channel (PDCCH) within time symbols from time symbol #0 to time symbol #N−1 for downlink control channel transmission in a transmission time interval (TTI). The user equipment receives downlink data on the basis of downlink control information carried by the PDCCH. Each of time symbol #0 to time symbol #N−1 includes a floor(X/N) number of decoding candidates. N is a maximum number of time symbols available for downlink control channel transmission in the TTI and is equal to or smaller than N, and X is a maximum number of decoding candidates for each TTI.
