Abstract:
1. A method for estimating a quality of service (QoS) experienced by a mobile device receiving a downlink signal repeated by a bi-directional repeater, the bi-directional repeater comprising a downlink power amplifier, the method comprising: receiving the downlink signal from a base station at the bi-directional repeater; amplifying and repeating the downlink signal for receipt by the mobile device; determining a received signal strength indicator (RSSI) value associated with the downlink signal received by the bi-directional repeater; determining a gain of the downlink power amplifier; estimating the QoS experienced by the mobile device without using any parameters measured at the mobile device itself based on the RSSI value, the gain, and an adjustment for loss in downlink signal strength due to travel in air between the bi-directional repeater and the mobile device; and estimating an increase in downlink signal strength received by the mobile device without using any parameters measured at the mobile device itself based on the RSSI value and the gain, wherein the estimated increase in downlink signal strength received by the mobile device is with respect to a an estimated downlink signal strength received by the mobile device without the bi-directional repeater.
