WIRELESS COMMUNICATION MACHINES AND METHODS AND COMPUTER-READABLE MEDIA

Abstract

The aspects described here relate to wireless communication methods including: reception, mobile termination (MT) of the backhaul node, and integrated access and backhaul (IAB). The first indicator for moving from the first IAB donor node linked to the first cell group and the first central unit (CU) to the second IAB donor node linked to the second cell group and the second CU, performed by the IAB node and based at least in part on receiving the first indicator, the first random access procedure to connect to the second cell group linked to the second IAB donor node, established by the TRB node alongside the first distributed unit (DU) function of the IAB node serving the third cell group and based on the performance of the first random access procedure, the second DU function serving the fourth cell group. In addition, the invention also refers to wireless communication devices and computer-readable media.
