摘要

Disclosed is a method and system for compensating for excessive attenuation on an RF connection between a remote radio head (RRH) and an antenna of cell site. In an example configuration, in which first and second RF carriers of a cell site traverse different RF paths between respective RRHs and respective antenna, the second RF carrier may be subject to more attenuation than the first. Consequently, antenna transmission power of the second RF carrier may be below one or another threshold. For communication services to user equipment devices that involve both the first and second RF carriers, the diminished antenna transmission power of the second RF carrier may cause service degradation. In accordance with example embodiments, a controlling network entity may determine that the power is diminished, and responsively reallocate transmission power from an underutilized carrier to the second carrier, thereby boosting its transmission power and remediating service degradation.

說明書

In further accordance with example embodiments, each of the first plurality of RF channels could be to a respective RF carrier of a first plurality of RF carriers, and similarly, each of the second plurality of RF channels could be to a respective RF carrier of a second plurality of RF carriers. In this configuration, removing the identified one or more other channels from service could entail the base station server directing the second RRH to disable those RF carriers of the second plurality of RF carriers that correspond to the identified one or more channels. Further, redistributing transmission power of the removed one or more other channels at the second RRH to the particular channel of the second plurality of RF channels could entail the base station server directing the second RRH to increase transmission power of the particular channel of the second plurality of RF channels by applying at least a portion of power previously allocated to the disabled RF carriers.
