Embodiment Construction

[0042] figure 1 A wireless communication system 100 with multiple wireless devices is shown. The wireless communication system 100 is widely deployed to provide various types of communication content, such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). The wireless device may be a base station 102, a wireless communication device 104, or a femto access point 106. figure 1 The core network 114 is also depicted in.

[0043] The core network 114 is the central part of the telecommunications network, which provides various services to customers connected to the core network 114. The core network 114 may be a single entity or multiple entities that facilitate wireless communication among multiple wireless communication devices 104. The core network 114 may include multiple processors in one or more locations. The core network 114...

Abstract

A method for reducing interference to wireless communication devices is described. It is determined that a base station is deployed with a first coverage area that overlaps a second coverage area of a femto access point. The base station uses a first carrier for wireless communications. The femto access point uses a second carrier for wireless communications. Transmissions by the femto access point interfere with transmissions by the base station. An amount of radio frequency (RF) leakage experienced by wireless communication devices communicating with the base station is estimated. Interference experienced by the wireless communication devices is minimized.

Description

[0001] Related application [0002] This application is related to U.S. Provisional Patent Application No. 61 / 179,455 filed on May 19, 2009, entitled "Femtocell Carrier and Power Adjustment to Minimize Interference to Non-Associated Users", and claims its priority. Technical field [0003] The present invention relates generally to wireless communication systems. More specifically, the present invention relates to a system and method for minimizing interference to non-associated users. Background technique [0004] The wireless communication system has become an important means used by many people in the world to communicate. The wireless communication system can provide communication for multiple mobile stations, each of which can be served by a base station. [0005] It is advantageous to use a local base station that provides service to a selected group of mobile stations. Compared with ordinary base stations, these local base stations can use less power and have a smaller cover...
