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

  • identification information of the first (theoretically) transmitted data packet among the first data packets continuously transmitted, for example, the identification information includes: the lowest sequence number of the data packet successfully received in order, the lowest sequence number of the data packet unsuccessfully received in order, the lowest sequence number of the retransmission data packet unsuccessfully received in order. For example, taking continuously successfully received data packets (that is, a group of successfully received data packets with continuous sequence numbers) as an example, according to the sequence number of the data packet, if the sequence numbers of successfully received data packets are data packet 1, data packet 2, and data packet 3, the identification information is the sequence number of data packet 1.
  • identification information of the last (theoretically) transmitted data packet among the first data packets continuously transmitted, for example, the identification information includes the largest sequence number among data packets sequentially lost, the largest sequence number of the data packet successfully received in order, and the largest sequence number of the retransmission data packet successfully received in order. Taking data packets which are lost during transmission and have continuous sequence numbers as an example, the identification information may be the largest sequence number among a group of lost data packets.
  • In order to better understand and explain the various information that may be carried in the above first message, the following uplink data packet is taken as an example to explain various information that may be included in the above first message.
