Abstract
(EN)

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.
