bilities in MR-DC, E-UTRA, and NR capability contain- ers. The MN then stores the retrieved capabilities and the corresponding filter in the core network for later use. A number of UE capabilities require coordination between E-UTRA and NR: band com- binations, baseband processing capabilities, and the maximum power for FR1 the UE can use in SCG. For these capabilities the MN decides how to resolve the dependency between MN and SN configurations. The MN then provides the resulting UE capabilities usable for SCG configuration to the SN. The SN may also indicate the desired UE capabilities to be used for SCG configuration. In this case it is up to the MN to accept or reject the request from the SN. 4.3.4.1.2 Radio Resource Coordination The MN and SN may also coordinate the use of their radio resources, for instance when a UE configured with MR-DC cannot simultaneously receive or transmit over both the links at the same time. Another important case is the one of spectrum sharing between LTE and NR. The MN and SN can exchange messages over the X2 and Xn interfaces to coordinate the use of the radio resources in a time-division multiplexed (TDM) manner. For a given UE, this is done via UE-specific signaling, including the Resource Coordination Information IEs in the relevant messages during the SN Addition/Modification procedures. On the other hand, the spectrum sharing is done via non-UE-associated signaling, using the E-UTRA-NR Cell Resource Coordination Request/Response messages. To this end, either the MN or the SN can include the Data Traffic Resource Indication IE, indicating in a semi-static manner the resource block allocation to LTE or NR. 4.3.4.1.3 Measurement Configuration and Coordination In MR-DC, UE measurements on neighbor cells can be configured independently by the MN and by the SN (only for intra-Radio Access Technology [RAT] measurements), with 4.3 Multi-Radio Dual Connectivity some coordination to ensure that UE capabilities in terms of measurement configuration are not exceeded.
