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.

As further shown, both example cell sites 112, 114 are coupled with network infrastructure 116 (e.g., including routers, gateways, switches, servers, etc.), which may provide connectivity with a transport network 118, such as the Internet for instance. In addition, each cell site is configured to provide one or more respective wireless coverage areas, such as sectors on particular carriers, in which to serve UEs. In particular, cell site 112 is shown providing one or more wireless coverage areas 120 in which to serve UEs, and cell site 114 is shown providing one or more wireless coverage areas 122 in which to serve UEs.

In practice, these cell sites may be arranged to provide wireless communication service in accordance with a defined air interface protocol, examples of which include, without limitation, Orthogonal Frequency Division Multiple Access (OFDMA) (e.g., Long Term Evolution (LTE), or Wireless Interoperability for Microwave Access (WiMAX)), Code Division Multiple Access (CDMA), Global System for Mobile Communication (GSM), or various wireless local area network protocols, such as IEEE 802.11 (WiFi), BLUETOOTH, or the like. The UEs operating in coverage of such a cell site may then be configured to communicate according to the same air interface protocol.
