1. A method of wireless communication performed by a user equipment (UE), the method comprising:
receiving, from a base station, a sidelink mode 1 resource grant of one or more sidelink resources for scheduling a physical sidelink shared channel (PSSCH) transmission to a second UE over the one or more sidelink resources in a sidelink, the sidelink mode 1 resource grant including a soft grant of at least one sidelink resource of the one or more sidelink resources, the soft grant including an indication that the at least one sidelink resource of the one or more sidelink resources is soft-granted for operation of the UE and the second UE in sidelink mode 1;
performing, prior to transmitting over the one or more sidelink resources, a re-evaluation of the at least one sidelink resource to determine whether the soft grant of the at least one sidelink resource collides with a resource reservation of the at least one sidelink resource from another UE operating in sidelink mode 2;
transmitting the PSSCH transmission to the second UE over the at least one sidelink resource in response to a determination, based on the re-evaluation of the at least one sidelink resource, that the soft grant of the at least one sidelink resource does not collide with the resource reservation of the at least one sidelink resource from the another UE operating in sidelink mode 2; and
upgrading at least one soft grant of the soft grant of the at least one sidelink resource to a legacy grant, wherein upgrading the at least one soft grant of the soft grant of the at least one sidelink resource to a legacy grant is based on a predetermined upgrading rule.
