Abstract
A method, system and apparatus for sharing of physical random access channel (PRACH) resources between New Radio (NR) and Long Term Evolution (LTE) radio access technologies (RATs) are disclosed. According to one aspect, a network node is provided. The network node includes processing circuitry configured to: receive a physical random access channel, PRACH, signal from a wireless device; correlate the PRACH signal with one of at least two orthogonal sequences from a common set of sequences shared among a first radio access technology, RAT, and a second RAT; and determine whether the wireless device is operating according to one of the first RAT and the second RAT based at least in part on the correlation.
