Claim 16:
17. A method, comprising:
receiving, by a fourth 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,
wherein the first UE receives from a second 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;
receiving, by the fourth UE from the first UE, the first at least one sidelink data transmission using the third at least one time-frequency resource; and
receiving, by the fourth 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.
