The invention is directed to guest-host emissive systems suitable for use with organic light emitting devices. For example, the method may include identifying at a user equipment that a transmission received on a downlink channel during a transmission timing interval is configured by a network entity for a DCH Measurement Occasion or an idle interval gap for IRAT measurements. The memory controller employs error detection and correction code that is used to detect storage subsystem failure during read accesses. It allows rapid processing of impulsive signals.
