Abstract
Methods, systems, and devices are described for initial power level selection on a physical random access channel in a wireless communications network. Initial power level selection may account for, or be based on, one or more channel conditions associated with the physical random access channel. Initial power level selection may be based on signaling of available initial power transmission levels and a reference signal received power measurement. The described features may be implemented as coverage enhancement techniques, for example, for machine-type communication (MTC).
