Abstract
A method for carrier determination, a terminal device, and a network device are provided. The method includes the following. A downlink control information (DCI) is received, where the DCI contains carrier indication information. A carrier corresponding to data transmission scheduled by the DCI is determined according to a format of the DCI and/or the carrier indication information, where the carrier is multiple carriers or one of the multiple carriers.
Claims11
A method for carrier determination, being applied to a terminal device and comprising:
- receiving a downlink control information (DCI), the DCI containing carrier indication information;
- and
- determining a carrier corresponding to data transmission scheduled by the DCI according to a format of the DCI and/or the carrier indication information, the carrier being a plurality of carriers or one of the plurality of carriers;
- wherein the format of the DCI is a first DCI format, the data transmission scheduled by the DCI corresponds to a plurality of first carriers, and the carrier indication information is used for determining the plurality of first carriers;
- wherein the carrier indication information indicates a first carrier identifier (ID), and a carrier ID corresponding to each first carrier among the plurality of first carriers comprises the first carrier ID;
- and
- wherein the first carrier ID is further used for determining a physical downlink control channel (PDCCH) candidate where the DCI is located.
4 more elements
A terminal device, comprising:
- a processor;
- a transceiver;
- and
- a memory configured to store computer programs;
- wherein the processor is configured to execute the computer programs stored in the memory to:
- cause the terminal device to receive a downlink control information (DCI), the DCI containing carrier indication information;
- and
- determine a carrier corresponding to data transmission scheduled by the DCI according to a format of the DCI and/or the carrier indication information, the carrier being a plurality of carriers or one of the plurality of carriers;
- wherein the format of the DCI is a first DCI format, the data transmission scheduled by the DCI corresponds to a plurality of first carriers, and the carrier indication information is used for determining the plurality of first carriers;
- wherein the carrier indication information indicates a first carrier identifier (ID), and a carrier ID corresponding to each first carrier among the plurality of first carriers comprises the first carrier ID;
- and
- wherein the first carrier ID is further used for determining a physical downlink control channel (PDCCH) candidate where the DCI is located.
9 more elements
A network device, comprising:
- a processor;
- a transceiver;
- and
- a memory configured to store computer programs;
- wherein the processor is configured to execute the computer programs stored in the memory to:
- cause the network device to transmit a downlink control information (DCI), the DCI containing carrier indication information, a format of the DCI and/or the carrier indication information indicating a carrier corresponding to data transmission scheduled by the DCI, and the carrier being a plurality of carriers or one of the plurality of carriers;
- wherein the format of the DCI is a first DCI format, the data transmission scheduled by the DCI corresponds to a plurality of first carriers, and the carrier indication information is used for determining the plurality of first carriers;
- wherein the carrier indication information indicates a first carrier identifier (ID) and a carrier ID corresponding to each first carrier among the plurality of first carriers comprises the first carrier ID;
- and
- wherein the first carrier ID is further used for determining a physical downlink control channel (PDCCH) candidate where the DCI is located.
