FIELD: wireless communication.
SUBSTANCE: invention relates to wireless communication; it can be used to transmit and receive a downlink data transmission channel. In a method for receiving a downlink signal, user equipment (UE) receives, in the first bandwidth part (hereinafter – BWP) of downlink (hereinafter – DL), downlink control information (hereinafter – DCI) containing BWP switching information, which indicates the switching of the active DL BWP from the first DL BWP to the second DL BWP, and transport block (hereinafter – TB) information, which is associated with TB for a physical downlink shared channel (hereinafter – PDSCH). A transmission configuration indicator (TCI) is determined for a set of control resources (base set) in the second DL BWP, based on the fact that DCI received in the first DL BWP indicates the switching of the active DL BWP.
EFFECT: increase in the accuracy and efficiency of evaluating PDSCH on the second BWP of DL.
