Abstract
Embodiments of this application provide a data transmission method and a device. The method includes: obtaining, by a terminal, first indication information or second indication information, where the first indication information is used to indicate that a reference signal is carried in a resource unit, and the second indication information is used to indicate that no reference signal is carried in a resource unit; and performing, by the terminal, data transmission according to the first indication information or the second indication information. The reference signal can be properly configured in the embodiments.
Claims24
A method comprising:
- obtaining, by a terminal device, downlink control information (DCI) from an access network device,
- wherein the DCI comprises information of a modulation and coding scheme (MCS) and information of a resource block allocation, and
- wherein the information of the resource block allocation indicates that a quantity of resource blocks are scheduled for data communication between the terminal device and the access network device;
- and
- performing, by the terminal device, the data communication with the access network device in one or more scheduled resource blocks according to the MCS,
- wherein when the quantity of the scheduled resource blocks is less than a preset quantity, information carried in the one or more scheduled resource blocks does not include any phase related reference signal, and
- wherein when the quantity of the scheduled resource blocks is greater than or equal to the preset quantity and a modulation order of the MCS is greater than or equal to a preset modulation order, the information carried in the one or more scheduled resource blocks includes at least one phase related reference signal.
A device comprising:
- a processor and a transceiver;
- wherein the processor is configured to:
- obtain, through the transceiver, downlink control information (DCI) from an access network device,
- wherein the DCI comprises information of a modulation and coding scheme (MCS) and information of a resource block allocation, and
- wherein the information of the resource block allocation indicates that a quantity of resource blocks are scheduled for data communication between the device and the access network device;
- and
- perform, through the transceiver, the data communication with the access network device in one or more scheduled resource blocks according to the MCS,
- wherein when the quantity of the scheduled resource blocks is less than a preset quantity, information carried in the one or more scheduled resource blocks does not include any phase related reference signal, and
- wherein when the quantity of the scheduled resource blocks is greater than or equal to the preset quantity and a modulation order of the MCS is greater than or equal to a preset modulation order, the information carried in the one or more scheduled resource blocks includes at least one phase related reference signal.
A method comprising:
- sending, by an access network device, downlink control information (DCI) to a terminal device,
- wherein the DCI comprises information of a modulation and coding scheme (MCS) and information of a resource block allocation, and
- wherein the information of the resource block allocation indicates that a quantity of resource blocks are scheduled for data communication between the terminal device and the access network device;
- and
- performing, by the access network device, the data communication with the terminal device in one or more scheduled resource blocks according to the MCS,
- wherein when the quantity of the scheduled resource blocks is less than a preset quantity, information carried in the one or more scheduled resource blocks does not include any phase related reference signal, and
- wherein when the quantity of the scheduled resource blocks is greater than or equal to the preset quantity and a modulation order of the MCS is greater than or equal to a preset modulation order, the information carried in the one or more scheduled resource blocks includes at least one phase related reference signal.
A device comprising:
- a processor and a transceiver;
- wherein the processor is configured to:
- send, through the transceiver, downlink control information (DCI) to a terminal device,
- wherein the DCI comprises information of a modulation and coding scheme (MCS) and information of a resource block allocation, and
- wherein the information of the resource block allocation indicates that a quantity of resource blocks are scheduled for data communication between the device and the terminal device;
- and
- perform, through the transceiver, the data communication with the terminal device in one or more scheduled resource blocks according to the MCS,
- wherein when the quantity of the scheduled resource blocks is less than a preset quantity, information carried in the one or more scheduled resource blocks does not include any phase related reference signal, and
- wherein when the quantity of the scheduled resource blocks is greater than or equal to the preset quantity and a modulation order of the MCS is greater than or equal to a preset modulation order, the information carried in the one or more scheduled resource blocks includes at least one phase related reference signal.
