    • Methods to manage multiple component carriers (CCs) efficiently in a mobile network with carrier aggregation (CA) enabled are proposed. For CC activation/deactivation, a single LCID value is used to represent both activation and deactivation command. A single command with multiple instructions is provided to activate and/or deactivate multiple CCs. In addition, unnecessary re-activation or re-inactivation of a CC is prevented, and explicit feedback for activation/deactivation is considered. For scheduling mechanism, a novel buffer status reporting (BSR) procedure is provided, where only one BSR is calculated after preparing all the transport blocks (TB) within one transmission time interval (TTI). Novel power headroom reporting (PHR) format and trigger are also provided. For DL-UL linking, various linking types are created based on whether there is carrier indicator field (CIF) in DL grant or UL grant. The various linking types are used in different applications to improve scheduling flexibility and load balancing.
    • 提出了在启用载波聚合(CA)的移动网络中有效管理多分量载波(CC)的方法。 对于CC激活/去激活,单个LCID值用于表示激活和停用命令。 提供具有多个指令的单个命令以激活和/或去激活多个CC。 另外,不必要地重新激活或重新激活CC,并且考虑了激活/去激活的显式反馈。 对于调度机制,提供了一种新的缓冲状态报告(BSR)过程,其中在一个传输时间间隔(TTI)中准备所有传输块(TB)之后仅计算一个BSR。 还提供了新的功率余量报告(PHR)格式和触发。 对于DL-UL链接,基于DL授权或UL授权中是否存在载波指示符字段(CIF)来创建各种链接类型。 各种链接类型用于不同的应用程序,以提高调度灵活性和负载平衡。

    • A method and an apparatus for decoding of a video bitstream are disclosed. In one embodiment, the method comprises: decoding a first coded block flag (cbf) of the color component indicating whether a current coding unit (CU) of the color component has at least one non-zero transform coefficient (830). According to the first cbf of the color component, the method further comprises decoding four second cbfs, each indicating whether one of four sub-blocks in the current CU of the color component has at least one non-zero transform coefficient (850). The residual quad-tree (RQT) of the current CU of the color component is determined based on the first cbf of the color component (870), or based on the first cbf and the second cbfs of the color component if the second cbfs exist (860). In another embodiment, the method comprises decoding a cbf associated with a transform unit (TU) and determining RQT of the TU based on the cbf, wherein said determining the RQT of the TU based on the cbf is the same for a luma component and a chroma component and the cbf is recovered from the video bitstream.

    • A method and apparatus for video coding including an Intra transform Skip mode is disclosed. When the transform Skip mode is ON for a transform unit, embodiments according to the present invention apply different coding processes to the transform unit. The coding process with the transform Skip mode ON uses a different scan pattern from the coding process with the transform Skip mode OFF. According to various embodiments, the transform Skip mode is enabled when the transform unit size is 4x4, the prediction unit and the transform unit having the same size, or the prediction unit uses an INTRA_NxN mode. When the transform Skip mode is enabled, a flag can be signaled in the bitstream to indicate the transform Skip mode selection. Furthermore, the flag can be incorporated in a picture level, a slice level or a sequence level of the video bitstream.

    • A method and apparatus for deriving a motion vector predictor (MVP) candidate set for motion vector coding of a current block. Embodiments according to the present invention determine a redundancy-removed spatial MVP candidate set by removing any redundant MVP candidate from the spatial MVP candidate set. The redundancy-removal process does not apply to the temporal MVP candidate. In another embodiment of the present invention, a redundancy-removed spatial-temporal MVP candidate set is determined and the number of candidates in the redundancy-removed spatial-temporal MVP candidate set is checked to determine whether it is smaller than a threshold. If the number of candidates is smaller than the threshold, a zero motion vector is added to the redundancy-removed spatial-temporal MVP candidate set. The redundancy-removed spatial-temporal MVP candidate set is then provided for encoding or decoding of the motion vector of the current block.
