Patent ID: 11737153

Abstract:
A wireless backhaul link is established via a low-band frequency division duplex (FDD) carrier between an integrated access and backhaul (IAB) node and an IAB donor node or between the IAB node and another IAB node that is linked to the IAB donor node, in which the IAB donor node provides a backhaul connection to a core network of a wireless carrier network. Further, one or more corresponding wireless backhaul links are established between the IAB node and one or more additional IAB nodes via one or more corresponding low-band FDD carriers. When a user device is determined to be in range of the IAB node for an establishment of a wireless access link via a mid-band FDD carrier or a time division duplex (TDD) carrier, the wireless access link is established between the IAB node and the user device via the mid-band FDD carrier or the TDD carrier.
