Abstract
The same or similar physical signals can be used for both user equipment (UE) and an integrate access backhaul (IAB) node. Different configurations of the resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes. In addition, to support topology formation, mobility/multi-connectivity procedures, and backhaul link management, periodic measurements and reports can be configured by a parent IAB node to a child IAB node UE function. This can comprise radio resource management (RRM), radio link monitoring (RLM), and beam management (L1-BM) measurements and reports.

A method, comprising:
- connecting, by first network equipment comprising a processor, a mobile equipment function of the first network equipment to second network equipment;
- in response to the connecting, receiving, by the first network equipment for the mobile equipment function, synchronization signal block data representative of a synchronization signal block measurement associated with a synchronization signal block;
- based on the synchronization signal block data, configuring, by the first network equipment, channel state data to be transmitted on a first beamwidth that is narrower than a second beamwidth associated with the synchronization signal block, resulting in configured channel state data;
- in response to a reference signal received power being determined to have satisfied a threshold, generating, by the first network equipment, measurement data representative of a radio resource management metric associated with the first network equipment;
- based on the configured channel state data, performing, by the first network equipment, a radio resource measurement, wherein the radio resource measurement comprises a beam management measurement associated with the second network equipment;
- and
- based on the beam management measurement and in accordance with the second network equipment, selecting, by the first network equipment, a transmission beam to be used by the first network equipment.
