Abstract
The present disclosure provides a method performed by a base station. The method comprises: generating and transmitting a Physical Random Access Channel (PRACH) configuration parameter for a User Equipment (UE); detecting a random preamble sequence and/or a corresponding PRACH resource set transmitted from the UE, so as to determine a type and/or a coverage enhancement level of the UE; and generating a Random Access Response (RAR) based on the type and/or the coverage enhancement level of the UE. The present disclosure also provides a method performed by a UE and correspondingly a base station and a UE. With the present disclosure, it is possible to increase resource utilization for LTE to support MTC UEs, improve frequency spectrum/energy efficiency, and reduce time/frequency resource conflicts between cells.
