Abstract:
1. A method for High Power User Equipment (HPUE) power class adaptation for coverage extension in Long Term Evolution (LTE), the method comprising: setting, by the HPUE, a variable maximum transmit power to an artificially low predefined level that is below a maximum capability of the HPUE; transmitting, by the HPUE, at an operating transmit power at or below the variable maximum transmit power as a function of wireless conditions detected by the HPUE, and reporting, by the HPUE to a serving evolved node B (eNB), a first power headroom as a function of the variable maximum transmit power; responsive to determining by the HPUE, as a function of wireless conditions detected by the HPUE, that an increase in HPUE wireless transmit range is required, raising, by the HPUE, the variable maximum transmit power towards or to the maximum capability of the HPUE; transmitting, by the HPUE, at an operating transmit power at or below the raised variable maximum transmit power as a function of the detected wireless conditions and reporting, by the HPUE to the serving eNB, a second power headroom as a function of the raised variable maximum transmit power.
