Abstract: A method, apparatus, and computer program product provide for controlling access attempts for wireless backhaul. In the context of a method, the method constructs an access request comprising an Integrated Access and Backhaul (IAB) access indication. The method further determines whether the access attempt is allowed for a particular cell, and if so, determines an establishment cause value based at least on the IAB access indication. The method also causes transmission of the access request and establishment cause value.
