Abstract: A method of decoding video data by a device is provided. Level values corresponding to a chroma coding block are received. The chroma coding block is one of chroma coding blocks resulting from partitioning a chroma coding tree block. A luma coding tree block corresponding to the chroma coding tree block is partitioned into luma coding blocks which are organized into quantization groups such that luma quantization parameters are determined for the luma coding tree block. One of the luma quantization parameters that is mapped to the chroma coding block is identified. A predictive quantization parameter is derived by using a value derived from the identified luma quantization parameter. A chroma quantization parameter is determined by adding a delta quantization parameter associated with each of the chroma coding blocks to the predictive quantization parameter. Transform coefficient values are generated based on the determined chroma quantization parameter.

Abstract: Some of the present implementations provide a method for assembling a target SIB for a target service. The method receives, from a first cell on a first frequency carrier, a plurality of SIB segments of the target SIB, each of the plurality of SIB segments associated with a corresponding value tag. The method stores a first SIB segment in the plurality of SIB segments in a memory of the UE. For each subsequent SIB segment in the plurality of SIB segments, the method determines whether a corresponding value tag of the subsequent SIB segment is the same as the corresponding value tag of the first SIB segment and if they are the same, stores the subsequent SIB segment in the memory of the UE. The method then assembles the target SIB using the stored plurality of SIB segments.
