1. A method of allocating resources to at least one wireless node in a wireless communication network, said method comprising the step of:
a) continuously receiving, at a wireless node, assignment of a number of slots, wherein the slots have a fixed slot time, characterized in that the method further comprises the steps of:
b) obtaining (S1) information regarding physical layer parameters together with said assignment of said number of slots and said slot time,
c) extracting (S2) a packet from a packet transmission queue maintained by said wireless node,
d) computing (S3), based on the obtained information regarding physical layer parameters, a duration of said packet,
e) comparing (S4A, S4B, S4C) said packet duration with said fixed slot time,
f) performing in real time at least one of fragmentation (S5C), aggregation (S5A) and reconfiguration (S5B) of said physical layer parameters, depending on the results of said comparison step and/or an amount of packets in said packet transmission queue, wherein said physical layer parameters comprise one or both of modulation order or cyclic prefix length,
wherein in step f) it is determined to perform the reconfiguration of said physical layer parameters in response to said comparison indicating that the packet duration is shorter than said fixed slot time and no further packets are in said packet transmission queue, and/or
wherein in step f) it is determined to perform the reconfiguration of said physical layer parameters in response to said comparison indicating that the packet duration is longer than said fixed slot time, and
g) mapping (S6) said packet to a first slot of the assigned number of slots.
