Abstract:
Various communication systems may benefit from improved random access procedures. For example, it may be helpful to improve random access procedure when changing a coverage enhancement level. A method, according to certain embodiments, may include changing a coverage enhancement level in response to a failure of a random access procedure. The method may also include determining whether early data transmission may be initiated in the changed coverage enhancement level. In addition, the method may include building at a user equipment a protocol data unit corresponding to the changed coverage enhancement level when the early data transmission is initiated in the changed coverage enhancement level. Further, the method may include transmitting the early data from the user equipment to a network entity in the built packet data unit on the changed coverage enhanced level.
