Abstract:
A method for performing random access is provided. The method is performed for random access procedure based on a lower bound of back-off time and an upper bound of back-off time. Based on the proposed method, subsequent transmission of a random access preamble is determined by control information included in a random access response. The control information explicitly or implicitly indicates an upper bound and a lower bound of a back-off time value. An exact back-off time is selected from a uniform distribution between the lower bound and the upper bound.
