Claim 4:
5. A first user equipment (UE), comprising:
at least one processor; and
a non-transitory computer readable storage medium storing programming, the programming including instructions that, when executed by the at least one processor, cause the first UE to perform operations including:
selecting first at least one time-frequency resource for first at least one sidelink data transmission from the first UE to a fourth UE;
transmitting a first reservation signal indicating the first at least one time-frequency resource for the first at least one sidelink data transmission from the first UE to the fourth UE;
receiving, 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;
determining 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;
re-selecting third at least one time-frequency resource for the first at least one sidelink data transmission from the first UE to the fourth UE;
transmitting the first at least one sidelink data transmission using the third at least one time-frequency resource; and
transmitting 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.
