Apparatus, method for a radio communications network and use thereof

An apparatus (UE1) comprising at least one processor, at least one memory including computer program code, and at least one communication module, the at least one memory and computer program code configured, with the at least one processor, and the at least one communication module, to cause the apparatus (UE1) to:

• receive (102) a plurality of radio signals (s0, s2);
• determine (110) at least one communication parameter (cp) based on at least one of the radio signals (s0, s1);
• determine (104) at least one resource conflict indicator (RCI) based on the received radio signals (s0, s2) and sidelink control information (SCI) decoding, wherein sidelink control information (SCI) of at least one other apparatus (UE0, UE2) is decoded prior to determining (104) the at least one resource conflict indicator (RCI), wherein the decoded SCI includes overlapping reservations, wherein the at least one resource conflict indicator (RCI) indicates at least one radio resource (rr1) that has a potential risk of a resource conflict, and wherein the determined at least one communication parameter (cp) is mapped (114) to a transmission parameter (tp) for the resource conflict indicator (RCI);
• and
• transmit (106) the resource conflict indicator (RCI).
