1. A method for wireless communication, comprising:
- receiving, by a wireless device, signaling indicative of a set of initial transmission power levels and a set of reference signal received power (RSRP) threshold values corresponding to the set of initial transmission power levels;
comparing, by the wireless device, an RSRP measurement to the set of RSRP threshold values;
selecting, by the wireless device, an initial transmission power level from the set of initial transmission power levels based at least in part on the comparing; and
transmitting, by the wireless device, a random access channel (RACH) message utilizing the initial transmission power level.

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).
