Data transmission method and device, base station, network node and communication equipment

Abstract

The invention provides a data transmission method and device, a base station, a network node and communication equipment, and the method comprises the steps: determining whether relay reverse mappingis started between a target node and an adjacent node or not according to the capability information between the target node and the adjacent node; and if so, sending relay reverse mapping enabling information to the target node, wherein the capability information comprises uplink and downlink accessibility information and/or load information between the target node and an adjacent node. Accordingto the scheme, signaling interaction between the relay nodes can be supported and realized, so that uplink and downlink transmission adopts the same bearing to return relay link mapping, and the reciprocity of a wireless channel is fully utilized; a control plane signaling is replaced by a user plane associated signaling, so that the signaling overhead between the donor base station and the relaynode or the terminal is reduced, and the mapping change time delay is reduced; and the problem that signaling resources are wasted due to the fact that signaling interaction cannot be carried out between relay nodes in the prior art is well solved.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a data transmission method, device, base station, network node and communication equipment. Background technique [0002] With the emergence of data-based applications such as virtual reality and augmented reality, the current communication network capacity is increasingly unable to meet people's needs, and network densification has become an important means to increase network capacity. Densely deploying small base stations at sites such as street light poles and bus shelters requires a low-cost, fast-deployment, and easy-to-maintain backhaul solution. Wireless Mesh backhaul is characterized by its self-configuration, self-optimization, and fault-free The characteristic of healing has become a very competitive method. In order to further improve spectrum resource utilization, improve network reliability, provide more precise QoS (Quality of Service) management, load b...
