1. A method for resource reservation performed by a terminal device in connection with sidelink transmission on an unlicensed spectrum, the method comprising:
performing Listen Before Talk (LBT) on the unlicensed spectrum; and
sending sidelink control information after the LBT is successful, wherein the sidelink control information is used to indicate N transmission resources reserved for a first transport block, and an upper limit of N is an integer greater than 3,
wherein the sidelink control information comprises a first period field, and the first period field is used to indicate a first time-domain period between periodic transmission resource groups reserved for the first transport block, the transmission resource group comprises at least one transmission resource indicated by a time-domain resource assignment field and/or a frequency-domain resource assignment field,
wherein the sidelink control information further comprises a first period parameter field, and the first period parameter field is used to indicate the number of reserved periods of the transmission resource group, and
wherein the sidelink control information is used to indicate transmission resources reserved for M transport blocks, the M transport blocks comprise the first transport block, and M is an integer greater than 1, the sidelink control information further comprises a second period field and a second period parameter field, the second period field is used to indicate a second time-domain period between periodic transmission resource sets reserved for the M transport blocks, and the second period parameter field is used to indicate the number of reserved periods of the transmission resource set.
