System and method to enable resource partitioning in wireless networks

Abstract

Systems and methodologies are described that facilitate improved resource partitioning and interference management in a wireless communication system. Techniques are described herein for the transmission and use of various types of signaling, such as Access Request commands, Reverse Link Special Resource Utilization Message (R-SRUM) signaling, Forward Link Special Resource Utilization Message (F-SRUM) signaling, and the like, for managing interference associated with range extension, restricted association networks, and other jamming scenarios. As described herein, downlink resource coordination and interference management are accomplished through the use of Access Request or R-SRUM signaling conducted in a unicast or broadcast fashion, and uplink resource coordination and interference management are accomplished through the use of F-SRUM signaling. As further described herein, a clean communication channel such as a Low Reuse Preamble (LRP) channel can be utilized for interference management signaling and / or leveraged for determining timing of various signaling messages.

Description

[0001] Priority claim based on 35 U.S.C. §119 [0002] This application claims priority to U.S. Provisional Application No. 61 / 055,384, filed May 22, 2008, entitled "SYSTEM AND METHOD TO ENABLE RESOURCE PARTITIONING IN WIRELESS NETWORKS," which is hereby incorporated by reference in its entirety incorporated into this application. technical field [0003] Generally speaking, the present invention relates to wireless communication, and in particular, the present invention relates to techniques for resource and interference management in a wireless communication system. Background technique [0004] Wireless communication systems are widely deployed today to provide various communication services; for example, voice, video, packet data, broadcast and message services can be provided via such wireless communication systems. These systems may be multiple access systems capable of supporting communication for multiple terminals by sharing available system resources. Examples of...

Problems solved by technology

However, in cases where a mobile terminal establishes communication with a base station with a relatively low power level, one or more neighboring base stations with higher power levels can interfere with the terminal

A similar situation occurs on the uplink, where a mobile terminal transmitting at a relatively high power level to a distant base station interferes with the uplink communications of one or more base stations closer to the mobile terminal. interference

[0010] Furthermore, in dominant interference situations such as those described above, in some cases, regular access requests transmitted by a mobile terminal to a desired serving base station may fail to be received by said base station due to uplink interference

Furthermore, if the base station recognizes and responds to this regular access request, in some cases the terminal may not be able to receive this response due to downlink interference
