摘要

The disclosure relates to a pre-5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). a communication method, apparatus, electronic device, and computer-readable storage medium, and relate to the field of wireless communication technology are provided. The method may be executed by the first node, and may include receiving a first message transmitted by a second node, wherein the first message is used by the first node to configure transmission and/or storage of a user data packet. Based on the solution provided by the embodiments of the disclosure, it may effectively improve one or more of the following problems: data packet loss, network resource waste, transmission failure and the like that may be caused by the migration of relay nodes in the network.

說(shuō)明書

  • The starting sequence number of the successfully received data packet, such as PDCP SN, NR-U sequence number. In an embodiment, the starting sequence number is the lowest sequence number of the data packet among a group of successfully received data packets with consecutive sequence numbers. In another embodiment, the starting sequence number is the sequence number of the first successfully received data packet among a group of data packets.
  • the termination sequence number of the successfully received data packet, such as PDCP SN, NR-U sequence number. In an embodiment, the termination sequence number is the largest sequence number of the data packet among a group of successfully received data packets with consecutive sequence numbers. In another embodiment, the termination sequence number is the sequence number of the last successfully received data packet among a group of data packets.
  • the bitmap information indicating whether the data packet is successfully received. Each bit in the bitmap indicates whether the corresponding data packet is successfully received, for example, “1” represents successful reception, “0” represents unsuccessful reception, or “1” represents unsuccessful reception, “0” represents successful reception.
  • In an embodiment, the successfully received data packet may include multiple groups of data packets with consecutive sequence numbers. For each group of data packets with consecutive sequence numbers, at least one of the above information (for example, the starting sequence number of the successfully received data packet, the termination sequence number of the successfully received data packet, and the bitmap information indicating whether the data packet is successfully received) may be given separately.
