<p>Systems and methodologies are described that facilitate optimizing parameters for random access in a wireless communication environment. A network manager can select centrally optimized parameters for random access that mitigate interference among RACH attempts and/or mitigate uplink interference due to RACH in a SON. Moreover, a base station can select locally optimized parameters for random access that mitigate a number of access attempts, mitigate interference among RACH attempts, and/or mitigate uplink interference due to RACH. The centrally optimized parameters can include PRACH configurations, root sequence parameters, ranges for one or more MAC parameters (e.g., initial transmit power, power ramp step, maximum number of preamble transmissions, contention resolution timer, . . . ), and so forth. Further, the locally optimized parameters can include sequence length, one or more MAC parameters (e.g., initial received target power of the random access preamble, power ramp step, contention resolution timer, maximum number of preamble transmissions, . . . ), etc.</p> |
