Data transmission method, terminal device and network device

A terminal device, comprising:

• a first processor, configured to determine a transmission parameter of a data channel based on data channel configuration information corresponding to a control resource set (CORESET) or a search space;
• and
• a first transceiver, configured to transmit or receive the data channel based on the transmission parameter;
• wherein the first transceiver is configured to acquire a correspondence between identification information of the CORESET or the search space and identification information of the data channel configuration information through a higher layer signaling from the network side;
• wherein the CORESET or the search space is a CORESET or a search space where downlink control information (DCI) for scheduling the data channel is detected;
• or, the CORESET or the search space is a CORESET or a search space using same quasi-co-location (QCL) type D assumption as a control channel for scheduling the data channel.

A non-transitory computer readable storage medium, storing a computer program that causes a computer to execute a method for data transmission, the method comprising:

• determining a transmission parameter of a data channel based on data channel configuration information corresponding to a control resource set (CORESET) or a search space;
• and
• transmitting or receiving the data channel based on the transmission parameter;
• wherein the method further comprises:
• acquiring a correspondence between identification information of the CORESET or the search space and identification information of the data channel configuration information through a higher layer signaling from the network side;
• wherein the CORESET or the search space is a CORESET or a search space where downlink control information (DCI) for scheduling the data channel is detected;
• or, the CORESET or the search space is a CORESET or a search space using same quasi-co-location (QCL) type D assumption as a control channel for scheduling the data channel.
