Method for transmitting configuration information and terminal device

A method for transmitting configuration information, comprising:

• receiving, by a second terminal device, a first sidelink transmission channel, the first sidelink transmission channel being configured to indicate configuration information of a slot format,
• wherein the configuration information indicated by the first sidelink transmission channel is used for communication between a first terminal device and the second terminal device,
• wherein the configuration information of the slot format comprises:
• a period of configuration information of a slot structure,
• wherein the configuration information of the slot format is used for determining time-domain positions of an uplink symbol in a slot.

A first terminal device, comprising:

• a processor, configured to generate configuration information of a slot format;
• and
• a transceiver, configured to send a first sidelink transmission channel, wherein the first sidelink transmission channel is configured to indicate the configuration information generated by the processor and the configuration information indicated by the first sidelink transmission channel is used for communication between the first terminal device and a second terminal device,
• wherein the configuration information of the slot format comprises:
• a period of configuration information of a slot structure,
• wherein the configuration information of the slot format is used for determining time-domain positions of an uplink symbol in a slot.
