1. A user equipment (UE) configured as an assisting sidelink UE for inter-UE coordination of sidelink communications in a wireless communication network, comprising:
one or more transceivers;
one or more memories; and
one or more processors coupled to the one or more transceivers and the one or more memories, wherein the one or more processors are configured to:
sense a first transmission from a first sidelink UE, the first transmission identifying a first resource to be used by a second sidelink UE in a first response to the first transmission;
sense a second transmission from the second sidelink UE, the second transmission identifying a second resource to be used by the first sidelink UE in a second response to the second transmission;
send a conflict indication to at least one of the first sidelink UE or the second sidelink UE in response to determining the first resource conflicts with the second resource; and
send the conflict indication to one of either the first sidelink UE or the second sidelink UE according to a predefined rule, wherein the predefined rule indicates that the conflict indication is sent to the first sidelink UE or the second sidelink UE having a smaller Layer-1 source identifier (ID).
