    摘要： Combined Intra prediction is disclosed. The combined Intra prediction is generated for encoding or decoding of a current chroma block by combining first Intra prediction generated according to the first chroma Intra prediction mode and second Intra prediction generated according to the second chroma Intra prediction mode. The second chroma Intra prediction mode belongs to an Intra prediction mode group excluding any LM mode. Multi-phase Intra prediction for a chroma component of non-444 colour video data is also disclosed. A mode group including at least two LM modes are used for multi-phase Intra prediction, where mapping between chroma samples and corresponding luma samples is different for two LM modes from the mode group. Furthermore, chroma Intra prediction with one or more LM modes using extended neighbouring area to derive LM mode parameters is also disclosed.

    摘要： Apparatus and methods are provided for decoding DL PHY channels in a narrow band wireless system. In one novel aspect, the UE performs a cell search and determines a first location of a resource block carrying system signals, obtains a second location of a second resource block based on the first resource block, wherein the second resource block includes a format indicator, determines a DL transmission format based on the format indicator, and receives and decodes a first DL physical channel based on the DL transmission format. In one embodiment, the UE operates in either a standalone mode, an in-band mode, or a guard-band mode. The DL transmission format comprises an offset index from a middle/central frequency of the first resource block in the in-band mode or the guard-band mode. In another embodiment, the UE further decodes a second DL physical channel carrying the format indicator.
