1. An information determination method, applied in a terminal device, the method comprising:
determining, when no antenna port field exists in a format of first Downlink Control Information (DCI), a first Demodulation Reference Signal (DMRS) port used for transmission scheduled by the first DCI, and/or a first antenna port used for transmission scheduled by the first DCI,
wherein the first DMRS port is determined based on an identification of the first antenna port and a quantity of orthogonal DMRS ports supported by the terminal device,
wherein the first DMRS port is determined based on a remainder between the identification of the first antenna port and the quantity of orthogonal DMRS ports supported by the terminal device.
