20210160929 | METHOD, NETWORK NODE AND USER EQUIPMENT FOR PREAMBLE SEQUENCE TRANSMISSION AND RECEPTION TO CONTROL NETWORK TRAFFIC - The method includes receiving indicator information indicating a processor should use a first type preamble sequence or a second type preamble sequence to generate a first preamble sequence, generating the first preamble sequence, transmitting a first request message to request network resources, the first request message including the first preamble sequence, a processor being capable of generating both the first type preamble sequence and the second type preamble sequence for the first request message to initially request network resources, receiving a feedback message from the receiver, and controlling the network data traffic based on the feedback message. The second type preamble sequence has a higher robustness against frequency impairments compared to the first type preamble sequence. The second type preamble sequence is used in high carrier frequency scenarios, within 5G networks, in case of low-cost terminals, or in ultra-reliable and low latency communication (URLLC) use cases. | 2021-05-27 |
