Problems solved by technology

[0008] RF interference issues can arise because mobile operators may not optimize the radio frequency ("RF") coverage of small-coverage base stations and the deployment of such base stations may be ad-hoc
Also, soft handover may not be supported for small coverage base stations

Abstract

Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and / or an attenuation profile. Interference also may be managed through the use of power management-related techniques.
