Abstract:
1. A computer-readable medium having computer-executable instructions for performing steps of a power control scheme for network communications between a base station and a plurality of mobile devices, the steps comprising: setting, by the base station, a target signal quality value for each of the mobile devices through a constrained maximization calculation to maximize a total effective data rate of wireless transmissions from the mobile devices; periodically deriving, by the base station a measured value of a signal quality parameter for each mobile device based on transmissions received from said each mobile device; comparing, by the base station, the measured values of the signal quality parameter for said each mobile device to the target signal quality value for said each mobile device; transmitting, by the base station, an instruction signal to said each mobile device to adjust a transmission power of said each mobile device; determining, by said each mobile device in response to the instruction signal from the base station, an amount of adjustment to a transmission power of said each mobile device based on a constrained minimization calculation to minimize a total power consumption of said each mobile device via a reallocation of power among the transmission power and coding components of the total power consumption; and adjusting, by said each mobile device, the transmission power by said amount of adjustment in conjunction with the reallocation of power to the coding components of the total power consumption, and, wherein the reallocation of power results in a changed error protection level of said each mobile device, the computer-readable medium including further computer-executable instructions for said each mobile device to send an information packet to the base station specifying the changed error protection level of said each mobile device.
