| 20080254760 | Adaptive Power Control Data Transmission Systems and Methods - Systems and methods of performing power control in combination with AMC are provided. AMC is performed on the basis of an AMC parameter such as CINR. Once the AMC is set to a highest available AMC for transmission to a given receiver, if the CINR indicates that the highest AMC could be transmitted with less transmit power, the power is reduced. For receivers that are not receiving the highest available AMC for that receiver, they may have their transmit power increased. | 10-16-2008 |

| 20110075587 | OFDM SYSTEM WITH REVERSE LINK INTERFERENCE ESTIMATION - A new method of performing interference estimation to allow the data packets to be efficiently delivered in an OFDM system. The interference estimation is performed on average over each frame for each mobile station individually in both frequency and time domains. Based on the estimated interference, the CIR can be determined by the BTS based on channel response estimates made by the BTS, or by the MS based on channel response estimates made for the uplink assuming a symmetrical channel. Numerical results show that the CIR estimation error could be very small if a sub-channel is considered as the minimum transmission unit. In terms of the aggregate throughput, the interference estimation method can provide a significant gain. | 03-31-2011 |
