摘要： Methods and apparatus are provided for paging enhancement for LC-MTC devices. In one novel aspect, a new paging message is used. In one embodiment, a new system information (M-SI)-paging is provided either carrying a bitmap or being generated from specific M-P1-RNTI sequences to indicate the modified SI messages. In another embodiment, a new RRC-paging is used through a UE-specific message, a multicast message, or a broadcast message to inform a UE to establish a RRC connection. The new paging message is either a sequence or an encoded data packet transmitted without control information, or scheduled by M-PDCCH. In another novel aspect, the new paging message is transmitted within one or more cells by a broadcast mechanism to achieve a maximal CE level the one or more cells support, or a multi-cast mechanism to support a specified CE level range, or a unicast mechanism to support a CE level.

摘要： A method and apparatus for sharing context among different SAO syntax elements for a video coder are disclosed. Embodiments of the present invention apply CABAC coding to multiple SAO syntax elements according to a joint context model, wherein the multiple SAO syntax elements share the joint context. The multiple SAO syntax elements may correspond to SAO merge left flag and SAO merge up flag. The multiple SAO syntax elements may correspond to SAO merge left flags or merge up flags associated with different color components. The joint context model can be derived based on joint statistics of the multiple SAO syntax elements. Embodiments of the present invention code the SAO type index using truncated unary binarization, using CABAC with only one context, or using CABAC with context mode for the first bin associated with the SAO type index and with bypass mode for any remaining bin.
