First Claim
Patent Images
1. A method of power control for a wireless device in a wireless communications system, the method comprising:
- determining an initial uplink power based at least in part on a first channel repetition level;
identifying one or more repetition thresholds;
applying a maximum power value when the first channel repetition level exceeds one of the one or more repetition thresholds; and
transmitting a first uplink channel according to the initial uplink power or the maximum power value.

Abstract
Methods, systems, and devices are described for uplink power control in a wireless communications network. Power settings for various uplink transmissions may account for, or be based on, prior uplink channel repetition levels. Uplink power settings may also be based on other factors, including a power ramp-up associated with prior uplink transmissions. Certain uplink 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 machine-type communication (MTC).
