Abstract

A technology is described for increasing signal booster while maintaining network protections. A distance from the signal booster to one or more base stations can be estimated. A base station coupling loss (BSCL) value can be calculated based on the estimated distance. A gain and/or a noise power of an uplink signal of the frequency band can be adjusted based on the BSCL value while maintaining network protections.

Claims

measuring a downlink signal at a plurality of channels for a selected band to determine a base station coupling loss (BSCL) at each of the plurality of channels;

identifying a channel of the plurality of channels associated with a base station that is located nearest to the signal booster by determining a signal with a highest received signal strength indicator (RSSI) as the channel;

using a comb filter to receive the plurality of channels to enable delayed versions of each channel to be combined to determine the signal with the highest RSSI;

determining a base station coupling loss (BSCL) value for the channel of the plurality of channels; and

adjusting one or more of a gain and a noise power of an uplink signal of the signal booster based on the BSCL value of the channel to maintain the network protections.

2, 4, 5, 12, 13, 17, or 25.

4. The method of claim 1, further comprising measuring the downlink signal at the plurality of channels in one or more bands selected from:

third generation partnership project (3GPP) long term evolution (LTE) frequency division duplex (FDD) bands 1 through 33;

or

3GPP LTE time division duplex (TDD) bands 34 through 44.

5. The method of claim 1, further comprising removing a BSCL contribution of one or more signals broadcast in the plurality of channels from a broadband BSCL value of the downlink signal based on one of a frequency range of the plurality of channels and a BSCL value of each of the plurality of channels.
