Method, network node and user equipment for preamble sequence transmission and reception to control network traffic

At least a first network node in a communication network, comprising:

• at least one processor, configured to,
• receive, from a receiver, indicator information indicating that the at least one processor should use one of a first type of preamble sequence or a second type of preamble sequence in order to generate a first preamble sequence,
• generate the first preamble sequence,
• transmit a first request message to the receiver to request network resources, the first request message including the first preamble sequence, the at least one processor being capable of generating both the first type of preamble sequence and the second type of preamble sequence for the first request message for the first request message to initially request network resources, and
• receive a feedback message from the receiver, and
• control the network data traffic of the communication network based on the feedback message, and
• wherein the second type of preamble sequence has a higher robustness against frequency impairments compared to the first type of preamble sequence, and the second type of preamble sequence is used in at least one of high carrier frequency scenarios, within 5G networks, in case of low-cost terminals, or in ultra-reliable and low latency communication (URLLC) use cases.
