Abstract
Embodiments of this application provide a data transmission method, a terminal device and a network device, to reduce complexity of blindly detecting a PDCCH by the terminal device. The method includes: receiving by a terminal device, an SFI sent by a network device; determining, by the terminal device according to the SFI, at least one of a slot format in one time unit and a time length suitable for the slot format; and detecting, by the terminal device, a PDCCH according to the slot format corresponding to the one of the one or more slot format indices indicated by the SFI.
Claims16
A method for processing data in a wireless communication network, comprising:
- obtaining, by a terminal device, a slot format indicator (SFI), the SFI being used to indicate one or more slot format indices;
- obtaining, by the terminal device, one or more slot format indices according to the SFI;
- determining, by the terminal device, a slot format in a time unit according to one of the one or more slot format indices and a first correspondence relationship, wherein the first correspondence relationship is a relationship between a slot format index and a slot format;
- and
- receiving, by the terminal device, a physical downlink control channel (PDCCH) according to the slot format corresponding to the one of the one or more slot format indices indicated by the SFI, wherein the SFI is carried in downlink control information (DCI) and the DCI is scrambled by using a radio network temporary identifier (RNTI).
A terminal device in a communication device, comprising:
- a processor and memory storing program instructions;
- wherein the program instructions, when executed by the processor, cause the terminal device to:
- obtain a slot format indicator (SFI), the SFI being used to indicate one or more slot format indices;
- obtain one or more slot format indices according to the SFI;
- determine a slot format in a time unit according to one of the one or more slot format indices and a first correspondence relationship, wherein the first correspondence relationship is a relationship between a slot format index and a slot format;
- and
- receive a physical downlink control channel (PDCCH) according to the slot format corresponding to the one of the one or more slot format indices indicated by the SFI, wherein the SFI is carried in downlink control information (DCI) and the DCI is scrambled by using a radio network temporary identifier (RNTI).
