Abstract
In one embodiment, a method in a user equipment (UE) for random access (RA) coverage enhancement (CE) is disclosed. The method includes transmitting a random access preamble to a UE, wherein a power of the random access preamble is determined, in part, by a current CE level. The method further includes incrementing a value of a counter by one, wherein the value of the counter indicates a number of random access preambles previously transmitted by the UE. The method may then compare the value of the counter after incrementing its value, to a transmission limit, wherein the transmission limit indicates a maximum number of random access preamble transmission attempts for the current CE level. In response to the counter being equal to the transmission limit plus one, the method includes resetting the value of the counter.
