A method and apparatus for signaling a message regarding UE receiver performance degradation between a user equipment and a network. Close UL/DL frequencies or harmonic relationships may cause MSD. A user equipment may indicate an actual or improved maximum sensitivity degradation value for a configuration, or that there is no maximum sensitivity degradation for a configuration, using capability transfer signaling, RRC reconfiguration signaling, and/or measurement reporting. The indicated maximum sensitivity degradation for a configuration may be found in a table. The user equipment may additionally signal information about configuration(s) it supports and/or measurements it has made related to cross band transmit-to-receive degradation and/or SINR. A UE may implicitly indicate a MSD value through selection of a bandwidth combination set. MSD may be used by the network to assist in making scheduling decisions.
