ESTIMATING QUALITY OF A SIGNAL IN MOBILE WIRELESS COMMUNICATION SYSTEMS
First Claim
1. A method to determine signal quality values in a wireless network, comprising:
- determining a signal power value of a signal received from a plurality of antennas using a second preamble included in a super-frame of the signal, wherein the second preamble includes cell information,determining a noise power value of the signal received from the plurality of antennas using a first preamble included in the super-frame of the signal, wherein the first preamble includes carrier information,determining an interference power value of each sector within a cell using the second preamble,applying fractional frequency reuse power boosting to the interference power in each sector within the cell, anddetermining one or more signal quality values using one or more of the signal power value, the noise power value, and the interference power value.

Abstract
A mobile station (MS) to determine signal quality values is disclosed. The MS may include a transmitter and a receiver and the receiver may determine a signal power value, a noise power value, and an interference power value of a signal received from antennas. The receiver may determine the signal power value and the interference value using a second preamble included in a super-frame of the signal, wherein the second preamble includes cell information. The receiver may determine a noise power value of the signal received from the plurality of antennas using unoccupied orthogonal frequency division multiple access (OFDMA) tones of a first preamble included in the super-frame of the signal, wherein the first preamble includes carrier information. The receiver may also use the fractional frequency reuse (FFR) and MIMO features to determine signal quality values using the signal power value, the noise power value, and the interference power value.
