Packet-dependent logical channel restriction

An apparatus, comprising:

• at least one processor;
• and at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
• receive a configuration message from a node of a network, the configuration message representing criteria relating to characteristics of uplink data packets;
• and
• generate a logical channel mapping restriction rule based on the criteria relating to characteristics, the logical channel mapping restriction rule identifying a first set of uplink data packets to be sent to the network using a first logical channel and a second set of uplink data packets to be sent to the network using a second logical channel, wherein the configuration message includes a value of at least one parameter identifying at least one uplink data packet to be sent to the network using the second logical channel;
• and
• wherein the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to generate the logical channel mapping restriction controlling rule is further configured to cause the apparatus to:
• receive a sequence number of an uplink data packet;
• and
• determine whether the uplink data packet is included in the first set of uplink data packets or the second set of uplink data packets based on based on the sequence number and the value of the at least one parameter,
• wherein the configuration message includes values of a parameter K representing a number of uplink data packets in a survival time cycle and a parameter X identifying an uplink data packet within the survival time cycle to be sent to the network using the second logical channel,
• wherein generating the logical channel mapping restriction controlling rule includes receiving a sequence number of an uplink data packet and determining whether the uplink data packet is included in the first set of uplink data packets or the second set of UL data packets based on based on the sequence number and the values of the parameter K and the parameter X,
• wherein determining whether the UL data packet is included in the first set of uplink data packets or the second set of UL data packets includes generating a remainder value as a sequence number modulo the value of the parameter K and in response to the value of the parameter X being equal to the remainder value, including the uplink data packet in the second set of UL data packets and in response to the value of the parameter X not being equal to the remainder value, including the uplink data packet in the first set of uplink data packets.
