Wireless communication method and terminal device

A wireless communication method, comprising:

• sending, by a network device, first Downlink Control Information (DCI) to a terminal device, wherein the first DCI is used for the terminal device to perform at least one of determining whether an uplink transmission is allowed to be performed within a Channel Occupancy Time (COT) obtained by the network device, and determining content of first COT sharing indication information comprised in Configured Grant Uplink Control Information (CG-UCI), wherein the first COT sharing indication information is used to indicate whether a COT obtained by the terminal device is allowed to be shared with the network device, and wherein a resource used for the uplink transmission is a Configured Grant (CG) uplink resource in the COT obtained by the network device,
• wherein at least one of the following:
• the first DCI comprises second COT sharing indication information, and the second COT sharing indication information is used to determine whether the terminal device is allowed to share the first Configured Grant (CG) uplink resource in the COT obtained by the network device to transmit a Configured Grant Physical Uplink Shared Channel (CG-PUSCH);
• and
• the first DCI comprises Slot Format Indication (SFI) information, and the SFI information is used to determine whether the terminal device is allowed to share the first CG uplink resource in the COT obtained by the network device to transmit the CG-PUSCH.

A terminal device, comprising:

• a processor and a memory, wherein memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to perform operations of:
• performing, according to first Downlink Control Information (DCI) sent by a network device, at least one of determining whether an uplink transmission is allowed to be performed within a Channel Occupancy Time (COT) obtained by the network device, and determining content of first COT sharing indication information comprised in Configured Grant Uplink Control Information (CG-UCI), wherein the first COT sharing indication information is used to indicate whether a COT obtained by the terminal device is allowed to be shared with the network device, and wherein a resource used for the uplink transmission is a Configured Grant (CG) uplink resource in the COT obtained by the network device,
• wherein at least one of the following:
• the first DCI comprises second COT sharing indication information, and the second COT sharing indication information is used to determine whether the terminal device is allowed to share a first Configured Grant (CG) uplink resource in the COT obtained by the network device to transmit a Configured Grant Physical Uplink Shared Channel (CG-PUSCH);
• and
• the first DCI comprises Slot Format Indication (SFI) information, and the SFI information is used to determine whether the terminal device is allowed to share the first CG uplink resource in the COT obtained by the network device to transmit the CG-PUSCH.
