Systems and methods relating to the use of Beam Reference Symbols (BRSs) and BRS Received Power (BRS-RP) reporting for the selection of a beam for transmission to a wireless device from a first Radio Access Network (RAN) operating according to a first Radio-Access Technology (RAT) in a dual connectivity scenario in which control signaling (e.g., BRS-RP reporting) from the wireless device to the first RAN of the first RAT is transmitted via a second RAN of a second RAT. In particular, embodiments are disclosed for resolving timing and/or node ambiguity with respect to BRS-RP reporting.
