A message is transmitted indicating the first and the second MCS and also indicating the first resource blocks and the second resource block. Finally, a first PDU is transmitted to the remote unit or base station at a first time using the first MCS and the first resource blocks and a second PDU is transmitted to the remote unit or base station at the first time using the second MCS and the second resource block. | 09-11-2008 |
| 20080232240 | METHOD AND APPARATUS FOR RESOURCE ALLOCATION WITHIN A MULTI-CARRIER COMMUNICATION SYSTEM - A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced. | 09-25-2008 |

| 20090310589 | ADAPTIVE DC SUB-CARRIER HANDLING IN A RECEIVER - Receiving units will switch between performing a DC bias suppression and not removing the DC distortion at the receiver depending on the amount of DC interference level observed/measured/estimated. Since the overall DC interference is from all uplink transmitters, potentially at different power levels, the amount of DC distortion can be measured based on the difference between the received power level and the expected power level on the DC sub-carrier. Additionally it can be estimated based on the number of active transmitters, their allocation bandwidth, power control target and/or a rough estimate of the DC distortion introduced by each active transmitter and also the distortion introduced by the receiver. Once this distortion level is estimated, a decision is then made whether or not to remove the DC distortion. | 12-17-2009 |
