1. A terminal apparatus for communicating with a base station apparatus, the terminal apparatus comprising:
at least one processor; and
at least one memory coupled to the at least one processor, the at least one memory storing one or more computer-executable instructions that, when executed by the at least one processor, cause the terminal apparatus to:
receive, from the base station apparatus, a physical downlink control channel (PDCCH) including downlink control information (DCI) in a search space specific to the terminal apparatus and a physical downlink shared channel (PDSCH) scheduled by the DCI; and
determine a number of bits of a time domain resource allocation field in the DCI as ceiling(log 2(I)), in which the time domain resource allocation field is associated with a time domain resource allocation configuration and a default table for the PDSCH,
wherein:
when a radio resource control (RRC) parameter pdsch-TimeDomainAllocationList is received, I is given by a number of entries in the RRC parameter pdsch-TimeDomainAllocationList, and
when the RRC parameter pdsch-TimeDomainAllocationList is not received, I is given by a fixed number of entries in the default table.
