Pilot signal transmission management
First Claim
1. A base station, comprising:
- a wireless interface configured to provide wireless communication services to a first wireless communication device using a pilot signal emitted from the base station at a reduced power level lower than a nominal power level of the pilot signal;
a detector configured to detect a second wireless communication device within an area served by the base station; and
a controller configured to increase the pilot signal'"'"'s power level above the reduced power level in response to detecting the second wireless communication device.

Abstract
A base station is configured to reduce interference with other base stations and/or devices in a multi-cell wireless network. The base station includes a wireless interface, detector and controller. To reduce interference, the wireless interface may provide services to a first wireless communication device (WCD) using a pilot signal emitted from the base station at a reduced power level. In the reduced pilot signal mode, when the detector detects a second WCD within the base station'"'"'s service area, the controller increases the pilot signal'"'"'s power level above the reduced power level in order to establish communications with the second WCD. Upon successfully connecting to the first and second WCDs, the base station may again reduce the pilot signal'"'"'s power level to reduce interference with other base stations or wireless devices.
