1. A method implemented in a wireless device, WD, configured to communicate with a first network node of a Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) cell, the first network node being an LTE Master eNodeB, MeNB, and to communicate with a network node supporting at least one second cell of a second 3GPP New Radio (NR) RAT, the network node of the second RAT being a NR Secondary gNodeB, SgNB, the method comprising:
receiving, from the first network node, a request for a WD capability information;
as a result of the request, sending the WD capability information to the first network node, the WD capability information indicating that the WD is capable of at least one spectrum sharing capability, the WD capability information including at least one of radio resource control (RRC) parameters rateMatchingLTE-CRS, additionalDMRS-DL-Alt and rateMatchingResrcSetSemi-Static;
the at least one spectrum sharing capability including at least one of:
an LTE cell-specific reference signal (CRS) rate matching capability;
an additional demodulation reference signal (DMRS) position for LTE CRS co-existence with 3GPP NR capability; and
a general rate matching pattern to map around LTE synchronization signals and a physical broadcast channel (PBCH) capability;
receiving, from the first network node, a reconfiguration message configuring the WD to perform a B1 measurement on at least one 3GPP NR cell; and
performing the B1 measurement on at least one 3GPP NR cell after receiving the request for WD capability information from the first network node.
