Abstract
Integrated Access and Backhaul (IAB) nodes communicate with one another in half-duplex mode. Such a multiplexing of the communications of the IAB node requires simultaneous execution of a “mobile terminal” function and of a “base station” function by the IAB node. However, these two functions are not synchronised with one another, resulting in a lack of temporal alignment between the data communicated with the parent node and the data communicated with the child node, which causes interference that negatively impacts the quality of the communications between the different IAB nodes involved. Existing solutions suffer from long data processing times and are expensive. Accordingly, a time offset is introduced during the processing of the data by the child node, in order to take into account the lack of synchronisation between the “mobile terminal” function and the “base station” function of the current node.
