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.

說明書

The “uplink” in the embodiments of the disclosure refers to the direction of data from the UE to the network device, such as the direction from the UE to the relay node, the direction from the relay node to the donor node, for example, the relay node transmits a data packet to the donor node (or the central unit of the donor node, or the control plane part of the central unit of the donor node, or the user plane part of the central unit of the donor node), and the data packet may be called an uplink data packet. Correspondingly, “downlink” refers to the direction from the network device to the UE. For example, the donor node transmits data to the relay node, and the relay node transmits data to its lower-level node, and the relay node transmits data to the UE. For example, the donor node (or the central unit of the donor node, or the control plane part of the central unit of the donor node, or the user plane part of the central unit of the donor node) transmits a data packet to the relay node, and the data packet may be called a downlink data packet.

Taking the relay network shown in FIG. 1 as an example, the relay node 2 transmits data to the relay node 1, the relay node 1 transmits data to the donor node, and the user transmits data to the corresponding network access node (for example, the user 1 accesses the distributed unit of the donor node and the user 2 accesses the distributed unit of relay node 1), which belongs to the uplink data. The donor node, the relay node 1 and the relay node 2 transmits data to the corresponding users, the donor node transmits data (which belongs to the downlink data) to the relay node 1, and the relay node 1 transmits data (which belongs to the downlink data) to the relay node 2, which belongs to the downlink data.
