Abstract: One embodiment is directed to adaptive predictive uplink receive chain processing that involves determining predicted data for one or more early data symbols of a slot based on first baseband IQ data received for the slot. The predicted data for the early data symbols of the slot comprises a predicted version of data used at some point in performing a first portion of uplink receive processing for the early data symbols. The first portion of the uplink receive processing for the early data symbols of the slot is performed using the predicted data. Actual data corresponding to the predicted data is determined based on at least second baseband IQ data received for the slot. In connection with performing a remaining portion of the uplink receive processing for the early data symbols, the preliminary output data for the early data symbols of the slot are adapted based on the actual data.

Abstract: This disclosure relates to adaptive loop filtering (ALF) for cross-component sample offset (CCSO) and local sample offset (LSO). ALF uses reconstructed samples of a first color component as input (e.g., Y or Cb or Cr). For CCSO, the output is applied on a second color component which is a different color component of the first color component. For LSO, the output is applied on the first color component. A combined ALF may be generalized for CCSO and LSO by considering a delta value between neighboring samples of a collocated (or current) sample and also considering a level value of the collocated (or current) sample.

It was further surprisingly discovered that the polymer compositions described herein had improved mechanical performance (tensile strength and tensile elongation), relative to corresponding polymer compositions. Still further, the polymer compositions also unexpectedly had reduced (Tm-Tc) relative to corresponding polymer compositions and, therefore, provided faster cycle times for molded articles formed from the polymer compositions.
