Abstract
Methods and systems are provided for dynamic adjustment of the pilot-channel, paging-channel, and sync-channel transmission-power levels based on forward-link and reverse-link RF conditions. In an exemplary embodiment, a base station provides service on a carrier in a wireless coverage area, and computes both an Ec/Ior value and a reverse noise rise (RNR) value for the carrier. Based at least in part on the Ec/Ior value and at least in part on the RNR value, the base station adjusts at least one of a pilot-channel power level, a paging-channel power level, and a sync-channel power level for the carrier. As an example, if (a) Ec/Ior is above a first threshold and (b) RNR is below a second threshold, the base station may increase all three of the power levels, so as to improve service quality and coverage, among other advantages.
