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, by the wireless terminal, whether a frequency span of an n-th order convolution of a power spectral density function of an uplink signal overlaps with a spurious region, wherein n is one of at least 3 and 5; if it is determined that the frequency span of the n-th order convolution of the power spectral density function of the uplink signal overlaps with the spurious region, determining, by the wireless terminal, the maximum power reduction using a first map; if it is determined that the frequency span of the n-th order convolution of the power spectral density function of the uplink signal does not overlap with the spurious region, determining, by the wireless terminal, the maximum power reduction using a second map; and reducing, by the wireless terminal, transmit power of the wireless terminal based on the determined maximum power reduction.
