20 Claims

1. An apparatus comprising processing circuitry configured to perform operations comprising:

receiving information associated with a downlink reference signal for a first radio access technology (RAT), wherein the first RAT is different than a currently camped second RAT;

identifying reference signal occasions for the downlink reference signal;

receiving downlink control information from the second RAT via a physical downlink control channel (PDCCH); and

generating, for transmission to the currently camped cell of the second RAT, user equipment (UE) capability information indicating a UE is configured to perform rate matching around LTE cell specific reference signal (CRS) during PDCCH reception and wherein the indication is of per band reporting type.
