Claim 26:
27. A method for wireless communications at a first user equipment (UE), comprising:
transmitting a first sidelink control information message during a first transmission time interval of a first resource pool, the first sidelink control information message indicating a data message to be transmitted on a subchannel of a second resource pool to a second UE;
receiving a feedback message from the second UE for the first sidelink control information message during a second transmission time interval of the first resource pool;
determining whether to transmit the data message on the subchannel of the second resource pool based at least in part on the feedback message received from the second UE;
reserving, based at least in part on transmitting the first sidelink control information message, a third transmission time interval of the first resource pool;
transmitting a retransmission of the first sidelink control information message during the third transmission time interval of the first resource pool based at least in part on the feedback message indicating a negative acknowledgment, the retransmission of the first sidelink control information message indicating the data message to be transmitted on a second subchannel of the second resource pool to the second UE;
receiving a second feedback message from the second UE during a fourth transmission time interval of the first resource pool, the second feedback message indicating an acknowledgment for the retransmission of the first sidelink control information message; and
transmitting the data message on the second subchannel of the second resource pool based at least in part on the second feedback message.
