Techniques for determining valid (i.e., supported) TFCs from among all configured TFCs for normal and compressed modes. These techniques maintain sufficient historical information such that “TFC qualification” may be accurately performed. In a first scheme, Tx_power_requirement states are maintained for different combinations of each TFC. One combination is applicable for each TFC at each TFC interval, and valid TFCs are determined from applicable combinations in the proper state(s). In a second scheme, two Tx_power_requirement states are maintained for each TFC for the normal and compressed modes. In a third scheme, a single Tx_power_requirement state is maintained for each TFC for both modes based on a particular relative power requirement. In a fourth scheme, Tx_power_requirement states are maintained for a set of relative “bins” that cover the total range of required transmit power for all TFCs. And in a fifth scheme, a set of relative power requirement thresholds are maintained.
A method for determining transport format combinations (TFCs) supported for use in a wireless communication system, comprising:

A method for determining transport format combinations (TFCs) supported for use in a wireless communication system, comprising:
A method for determining transport format combinations (TFCs) supported for use in a wireless communication system, comprising:
A digital signal processor in a wireless communication system configured to determine a required transmit power for each of a plurality of combinations for each of one or more TFCs, wherein each TFC corresponds to a set of parameter values for a data transmission and each combination for each TFC corresponds to a particular transmission level for the data transmission, to determine a state of each combination for each TFC based on the required transmit power for the combination and a maximum available transmit power, and to select one combination for each of at least one TFC for possible use for an upcoming interval based on the state of each combination.
A transmitter unit in a wireless communication system, comprising:
A signal processing apparatus in a wireless communication system, comprising:
A digital signal processor in a wireless communication system configured to receive an indicator for each measurement period indicative of whether or not a required transmit power for each of a plurality of bins is supported by a maximum available transmit power, to identify a specific bin, from among the plurality of bins, that is applicable for an upcoming interval for each of one or more TFCs based on a required transmit power for the TFC for the upcoming interval, to determine a state of each TFC for the upcoming interval based on indicators derived for the bin applicable to the TFC, and to select one or more TFCs for possible use for the upcoming interval based on the state of each TFC.
A digital signal processor in a wireless communication system configured to determine a value indicative of transmit power available for a data transmission for each measurement period, to determine a state of each of one or more TFCs for an upcoming interval based in part on a plurality of values determined for a plurality of measurement periods, and to select one or more TFCs for possible use for the upcoming interval based on the state of each TFC.
