Method and system for managing transmit power on a wireless communication network
First Claim
1. A method for determining a maximum power reduction of an uplink signal, the uplink signal being transmitted on a carrier, the carrier having a range of frequencies, wherein frequencies outside of the carrier frequency range include adjacent channel regions, the method comprising:
- identifying resource blocks of the carrier that have been allocated to transmit the uplink signal;
determining, based on the identified resource blocks, a power spectral density function;
determining a metric, the metric being based on a third order self-convolution of the power spectral density function;
determining a maximum power reduction for the adjacent channel regions based on the determined metric; and
reducing, by a wireless terminal, transmit power of the wireless terminal based on the determined maximum power reduction.

Abstract
The present disclosure sets forth multiple embodiments of the invention. Among those embodiments is a method for determining a maximum power reduction of an uplink signal. The uplink signal is transmitted on a carrier that has a range of frequencies. Frequencies outside of the carrier frequency range include adjacent channel regions. Resource blocks of the carrier that have been allocated for use by to transmit the uplink signal are identified. A power spectral density is determined based on the identified resource blocks. A metric that is based on a third order convolution of the power spectral density function is determined. A maximum power reduction for the adjacent channel regions is also determined based on the metric.
