Title:
POWER COMPENSATION METHOD AND APPARATUS EMPLOYING WHITE SPACE OPTIMIZATION AND UTILIZATION TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2021/007894
Kind Code:
A1
Abstract:
A power compensation method and apparatus employing white space optimization and utilization technology. The method comprises: obtaining an available white space channel; and respectively and correspondingly compensating upper adjacent frequencies and/or lower adjacent frequencies of the channel according to a relationship between the coverage of licensed signals of adjacent frequencies of the channel and the coverage of a white space device, such that the white space device can obtain the maximum number of selectable channels and the maximum transmission power without affecting the licensed signals currently used in the adjacent frequencies. The invention is used to respectively enhance the emission intensities of TV broadcast signals or other licensed signals in adjacent frequencies of a white space channel, such that a white space device operating over the white space channel can meet the predetermined requirements of transmission power and coverage without adversely affecting the coverage and reception of licensed signals currently used in the adjacent frequencies.
