Repetition level coverage enhancement techniques for physical random access channel transmissions

摘要

Methods, systems, and devices are described for transmit power control and repetition levels of random access requests in a wireless communications network. Power settings and repetition levels for random access request transmissions may account for, and/or be based on prior power settings or prior uplink channel repetition levels. Power settings may also be based on other factors, including a power ramp-up associated with current or prior random access procedures. Power settings may be computed by a user equipment (UE) or they may be indicated to a UE from another system node. The described features may be implemented as coverage enhancement techniques, for example, for devices employing Machine Type Communication (MTC).
