NETWORK NODE AND METHOD FOR DYNAMIC SPECTRUM SHARING BETWEEN RADIO ACCESS TECHNOLOGIES

摘要

A method performed in a network node for configuring UE with dynamic spectrum sharing between a first RAT and a second RAT in a wireless communications system is disclosed. The network node configures an initial bandwidth part, BWP, for a UE, spanning across a dedicated spectrum for the first RAT and a shared spectrum between the first and second RATs, wherein synchronization signals of the first RAT are configured in the dedicated spectrum, and at least some other signals of the first RAT are configured in both dedicated and shared spectrum. The first RAT is NR and the second RAT is LTE.
