Radio resource configuration and measurements for integrated access backhaul for 5G or other next generation network
The same or similar physical signals can be used for both user equipment (UE) and an integrated access backhaul (IAB) node. Different configurations of resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes. In addition, since the UE functionality for IAB nodes is not fully identical with access UEs, the network can identify which UEs performing initial access are normal access UEs or are IAB nodes with UE functionality. Furthermore, the parameters for configuring radio resource management operation at the IAB node gNode B function can consider a half-duplex constraint imposed by the UE function and can also analyze hop order and other topology/route management functionalities.
