Abstract
The present disclosure provides an information determination method and apparatus, a device, and a storage medium, which relate to the field of mobile communications. The method includes: 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.
Claims11
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.
A terminal, comprising:
- a processor;
- a transceiver connected to the processor;
- a memory for storing executable instructions of the processor,
- wherein the processor is configured to load and execute the executable instructions to implement operations 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,
- 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.
A network device, comprising:
- a processor;
- a transceiver connected to the processor;
- a memory for storing executable instructions of the processor,
- wherein the processor is configured to load and execute the executable instructions to implement operations comprising:
- transmitting first Downlink Control Information (DCI) to a terminal device, wherein a quantity of bits of an antenna port field included in the first DCI is 0,
- wherein when the quantity of bits of the antenna port field is 0, it is determined that no antenna port field exists in a format of the first DCI,
- wherein the first DCI is transmitted to control the terminal device to determine, when no antenna port field exists in the format of the first 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.
