Claim 8:
9. A method, comprising:
receiving, by a second user equipment (UE) from a first UE, a first reservation signal indicating first at least one time-frequency resource selected by the first UE for first at least one sidelink data transmission from the first UE to a fourth UE;
transmitting, by the second UE to the first UE, a second reservation signal to indicate second at least one time-frequency resource for second at least one sidelink data transmission from the second UE to a third UE, the second reservation signal for the first UE to avoid using the second at least one time-frequency resource indicated by the second reservation signal,
wherein the first UE determines an overlap or a partial overlap between the second at least one time-frequency resource indicated by the second reservation signal and the first at least one time-frequency resource selected for the first at least one sidelink data transmission from the first UE to the fourth UE,
wherein the first UE re-selects third at least one time-frequency resource for the first at least one sidelink data transmission from the first UE to the fourth UE, and
wherein the first UE transmits the first at least one sidelink data transmission using the third at least one time-frequency resource; and
receiving, by the second UE from the first UE, a third reservation signal indicating the third at least one time-frequency resource for the first at least one sidelink data transmission from the first UE to the fourth UE.
