METHOD AND SYSTEM FOR MANAGING TRANSMIT POWER ON A WIRELESS COMMUNICATION NETWORK

摘要

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.

1. A method of determining a maximum power reduction of a wireless terminal, the method comprising:
determining whether a frequency span of the n-th order convolution of the power spectral density of the uplink signal overlaps with the spurious region; if it is determined that a frequency span of the n-th order convolution of the power spectral density of the uplink signal overlaps with the spurious region, determining a maximum power reduction using a first map; and if it is determined that a frequency span of the n-th order convolution of the power spectral density of the uplink signal does not overlap with the spurious region, determining a maximum power reduction using a second map.
