Claim 27:
28. A method for wireless communications at a second user equipment (UE), comprising:
receiving, from a first UE, 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 by the first UE on a subchannel of a second resource pool;
transmitting a feedback message to the first UE for the first sidelink control information message during a second transmission time interval of the first resource pool;
determining whether to monitor for the data message on the subchannel of the second resource pool based at least in part on the feedback message;
identifying a third transmission time interval of the first resource pool reserved by the first sidelink control information message;
receiving 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 from the first UE on a second subchannel of the second resource pool;
transmitting a second feedback message to the first 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
receiving the data message on the second subchannel of the second resource pool based at least in part on the second feedback message.
