1. A method, comprising:
- facilitating, by a system comprising a processor, an establishment of integrated links comprising an integration of wireless backhaul communications links and access communications links, wherein the facilitating the establishment comprises facilitating a first transmission of a multiplexed sync signal to enable synchronization between relay transmission point devices in a wireless communications network, and using a random-access channel procedure to complete the establishment, wherein;
the wireless backhaul communications links comprise first wireless communications transmission links between the relay transmission point devices,the access communications links comprise second wireless communications transmission links between user equipment and the relay transmission point devices, andthe random-access channel procedure comprises receiving a random-access channel procedure preamble;
in response to the receiving the random-access channel procedure preamble, facilitating a second transmission of a signal comprising a timing advance and a transmission grant allowing the relay transmission point devices to further communicate via the integrated links;
maintaining, by the system, the integrated links by measuring channel characteristics of the integrated links using a measurement reference signal; and
configuring, by the system, the wireless backhaul communications links using the channel characteristics.

Abstract
Establishment of integrated links comprising integrated wireless backhaul communications links and access communications links is facilitated by transmitting multiplexed sync signals to enable synchronization between the relay transmission point devices, and using a random access channel procedure to complete the establishment. The integrated wireless backhaul communications links and access communications links can be maintained by measuring channel characteristics of the backhaul communications links using a measurement reference signal.
