The embodiments of the invention, as described below, introduce a new full configuration flag to distinguish full configurations of low complexity category UEs from other categories. The new full configuration flag will also be referred to herein as an “enhanced” full configuration flag. A network node, such as a source eNB, can see the enhanced full configuration flag from the RRC configuration message that is prepared by another network node, for example a target eNB. If the target eNB sends a RRC configuration that contains a legacy version of the full configuration flag for a low complexity category UE, the source eNB knows that the target eNB does not comprehend Rel-12 and the low complexity category. Accordingly the source eNB can refrain from performing the handover. In addition, the UE can infer from the flag version if the target eNB has comprehended the UE category and accordingly it knows whether the configuration is valid or not. The embodiments of the invention described herein have the advantage that un-necessary signaling caused by failed handovers and unsuccessful RRC connection re-establishments are avoided. Consequently, network resources are used in a more efficient manner and UE battery lifetime is prolonged.

The present disclosure is directed to a process to partially or fully suppress, or limit, pixel coloration errors. These pixel coloration errors, represented by small noise values, can be introduced during signal processing of high dynamic range (HDR) video signals. Converting visual content to a half precision floating point representation, for example, FP16, can introduce small amounts of signal noise due to value rounding. The noise can be multiplied and accumulated during HDR signal processing resulting in visual artifacts and degraded image quality. The disclosure can detect these noise amounts in pixel color component values, and suppress, or partially suppress, the noise to prevent the noise from accumulating during subsequent HDR signal processing.
