Methods and apparatus are provided for resource allocation for a physical data channel. In one novel aspect, the UE obtains plurality definitions of resource block and selects one definition of resource block based on one or more selection conditions. The plurality definitions of resource block have reduced number of resource elements as the standard PRB pair. In one embodiment, the UE selects a definition of resource block based on conditions including a physical channel data type, a UE type of MTC, a transmission mode of coverage enhancement, and a transmission type of small data transmission. In another novel aspect, long TTI resource allocation is used. The UE determines a TTI length of a transport block based on corresponding resource block assignment with more than two consecutive time domain subframes such that the transport block fit in the assigned resource blocks. |
