摘要： A method in a wireless communication device includes determining a first configured maximum transmit power (PCMAX) value corresponding to a first set of resource blocks (RBs) in a carrier for a subframe, wherein the first set of RBs includes less than a complete set of RBs constituting the carrier, determining a second PCMAX value corresponding to a second set of RBs in the carrier for the subframe, wherein the first and second sets of RBs are of a common type and the second set of RBs is different from the first set of RBs and the second set of RBs includes less than the complete set of RBs constituting the carrier. A composite report for the subframe including the first and second PCMAX values is then sent to a base station.

摘要： The present invention provides a method of scheduling asynchronous transmissions for a plurality of subscriber units. The method includes receiving information associated with a plurality of subscriber units that have uplink data to transmit, the information including uplink timing offset information associated with each of the subscriber units. Two or more subscriber units are then selected from a set of subscriber units having a timing offset differential, that is below a predetermined threshold, where the timing offset differential is the difference between the timing offset of a first subscriber unit and the timing offset of a second subscriber unit further selectively offset by a multiple of the transmission segment size, which minimizes the difference. The transmission segments, which are available for the uplink of data, are then allocated between the selected two or more subscriber units, which limits the number of transmission segments that have at least one of an overlap or a gap, and the amount of any overlap or gap, in order to minimize wasted scheduling opportunities.

摘要： In a method of scheduling, a subframe (426) is communicated between a user equipment (102) and network equipment (110) wherein the subframe has a first transmission bandwidth configuration. The transmission bandwidth configuration includes a plurality of resource blocks and it least one of the resource blocks is configured as a control region (408). The control region includes an indicator that is used for scheduling a subsequent subframe (424). The method also uses the indicator to determine a transmission bandwidth of a second transmission bandwidth configuration for the subsequent subframe (421, 423). The second transmission bandwidth configuration can be adjusted by adjusting the power level of the resource blocks in the control region. In addition, The second transmission bandwidth configuration can be adjusted for a plurality of subsequent subframes.
