摘要： The present invention describes a RF signal control method and device that adjusts the first down-converter gain attenuation and uses the adjusted first down-converter gain attenuation to change the RF signal. The RF signal control method and device also uses a determined linear filter parameter to perform linearity improvement on the digital signal after the RF signal goes through a down-converter and analog-to-digital converter. The RF signal control method and device use an increased up-converter gain attenuation value to correct the RF input signal after digital pre-distortion operation, so that the adjusted and/or improved signals after power amplification have better quality than the RF signal with just a simple analog-to-digital converter and clipping equipment. Thus, the current application improves the linearity effect of digital pre-distortion operation and the dynamic effect of the power amplifier operation, thereby promoting the coverage effect of the RF output signal.

摘要： A resource allocation method and base station. The resource allocation method comprises: within a current scheduling period, determining priorities of users in a cell for sub-carriers in available frequency resources, and among the available frequency resources of the cell, allocating a corresponding available frequency resource for each user in the cell according to the priorities of all users for the sub-carriers, so that the frequency resources that can be used by the edge users cover all available frequency ranges of the cell. Therefore, when frequency selectivity fading occurs in the channel, a decline in communication quality caused by allocating carrier resources for the edge users in the limited frequency resources is avoided, the probability that the edge users use deeply fading frequency resources is reduced, and interruption in the communication process is decreased, thereby improving system throughput.
