1. A communication apparatus, configured in a terminal equipment, the apparatus comprising:
a receiver configured to receive downlink control information transmitted by a network device, the downlink control information being used to schedule Physical Downlink Shared Channel (PDSCH);
processor circuitry configured to receive a first PDSCH scheduled by the downlink control information according to spatial direction indication of the downlink control information,
wherein,
the spatial direction indication is indication of a Quasi Co Location (QCL) assumption or an indication of a transmission configuration indication (TCI) state for the first PDSCH;
the downlink control information comprises a TCI field;
when the number of the codepoints in the TCI field is smaller than the number of TCI codepoints activated by a Media Access Control Control Element (MAC CE) signaling, the first 2N TCI codepoints activated by the MAC CE signaling are applied to the downlink control information; where, N is the number of bits of the TCI field, N>0.
