Embodiment Construction

[0019] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration". Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

[0020] FIG. 1 shows a wireless multiple access communication system 100 . System 100 includes a number of base stations 110 that support communication for a number of wireless terminals 120 . Terminals 120 are typically dispersed throughout the system, and each terminal may be fixed or mobile. A terminal may also be called a mobile station, user equipment (UE), a wireless communication device, or some other terminology. A base station is a fixed station used for communicating with the terminals and may also be called an access point, Node B, or some other terminology. A system controller 130 is coupled to base stations 110, provides coordination and control for these base stations, and further controls the routing of ...

Abstract

Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. This may be done by combining interference information from multiple base stations.
