1. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory storing instructions, that when executed by the at least one processor, cause the apparatus at least to:
monitor if an assignment packet is received by a new node from a parent node;
set, when the assignment packet is received, a new value of an identifier for determining if a first packet of a first layer protocol is intended for the new node,
wherein the assignment packet comprises the new value of the identifier,
wherein the header of the assignment packet comprises the new value of the identifier,
wherein the assignment packet is a packet of the first layer protocol,
wherein the assignment packet comprises a header of the first layer protocol,
wherein the header includes a dedicated one bit flag, indicating that the header shall be used for adaptation layer address configuration,
wherein the assignment packet comprises as payload a second layer protocol data unit,
wherein the second layer protocol is on top of the first layer protocol, and
wherein a payload of the second layer protocol data unit comprises the new value of the identifier;
supervise if any value of the identifier is set, wherein the new value of the identifier is set only if any value of the identifier is not set; and
check if a connection according to a base layer protocol between the parent node and the new node is configured,
wherein the first layer protocol is directly on top of the base layer protocol,
wherein the earliest packet of the first layer protocol received by the new node after the connection according to the base layer protocol between the parent node and the new node is configured is identified as the assignment packet,
wherein only the earliest packet received by the new node after the connection according to the base layer protocol between the parent node and the new node is configured is identified as the assignment packet,
wherein the base layer protocol is a radio link control protocol.
