Problems solved by technology

This interference can degrade performance on the downlink and uplink
[0007] Furthermore, while highly loaded sectors may have lightly loaded neighbors, current server selection solutions typically do not take into account the load of neighbor cells

Abstract

A method of communicating in a wireless network including receiving effective load values for sectors accessible to an access terminal of the wireless network. The effective load values represent effective loads on the sectors. The method also includes receiving pilot signal channel quality values of the sectors and selecting a serving sector, for the access terminal based on the effective load values and the pilot signal channel quality values.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 358,539, filed June 25, 2010, entitled Load Balancing In Wireless Networks, under 35 U.S.C. §119(e), which is hereby incorporated by reference in its entirety expressly incorporated herein. technical field [0003] In general, aspects of the invention relate to wireless communication systems, and in particular, aspects of the invention relate to load balancing in wireless networks such as EVDO, HSPA and LTE networks. Background technique [0004] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and so on. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing available network resources. Examples of such multiple-access networks include Code Division Multiple Access (CDMA) networks, Time ...
