1. A method of wireless communication performed by a first wireless communication device, the method comprising:
receiving, from a second wireless communication device, a first-stage sidelink control information (SCI) comprising a reservation indicating a plurality of reserved physical sidelink shared channel (PSSCH) resources for a plurality of sidelink communications, wherein the reservation in the first stage SCI indicates:
an assignment of a first PSSCH resource of the plurality of reserved PSSCH resources for a first sidelink transmission from the first wireless communication device to a third wireless communication device, the first PSSCH resource being associated with a first frequency band; and
an assignment of a second PSSCH resource of the plurality of reserved PSSCH resources for a second sidelink transmission from the first wireless communication device to the second wireless communication device, the second PSSCH resource being associated with a second frequency band different from the first frequency band;
transmitting, to the third wireless communication device, the first sidelink transmission using the first PSSCH resource of the plurality of reserved PSSCH resources, wherein the first sidelink transmission comprises, in the first PSSCH resource, first sidelink data and a first second-stage SCI associated with the first stage SCI, the first second-stage SCI indicating a first modulation and coding scheme (MCS) associated with the first sidelink data; and
transmitting, to the second wireless communication device, the second sidelink transmission using the second PSSCH resource of the plurality of reserved PSSCH resources, wherein the second sidelink transmission comprises, in the second PSSCH resource, second sidelink data and a second second-stage SCI associated with the first-stage SCI, the second second-stage SCI indicating a second MCS associated with the second sidelink data.
