Abstract: In a wireless data network, such as a General Packet Radio Service (GPRS) network, a transmitter uses one of k coding/modulation schemes for transmitting data. The transmitter initially selects a coding/modulation scheme, C , as a function of carrier-to-interference ratio ( C / I ) measurements. The transmitter then calculates the number of blocks, B , required to transmit a number of data packets, D , using the coding/modulation scheme C . In addition, the transmitter calculates the number of blocks required to transmit the number of data packets, D , for each coding/modulation scheme that is stronger than the selected coding/modulation scheme C . The transmitter finally selects that coding/modulation scheme that results in transmitting the number of data packets D in B blocks using the strongest coding/modulation scheme. As a result, each block is transmitted using the strongest coding/modulation scheme available.

Abstract translation: 在诸如通用分组无线业务（GPRS）网络的无线数据网络中，发射机使用k个编码/调制方案之一来发送数据。 发射机最初选择编码/调制方案C作为载波干扰比（C / I）测量的函数。 然后，发射机使用编码/调制方案C来计算发送多个数据分组D所需的块数B。 此外，发射机对于比选择的编码/调制方案C更强的每个编码/调制方案，计算发送数据分组数目D所需的块数。 发射机最终选择使用最强编码/调制方案在B块中发送数据分组数目D的编码/调制方案。 结果，使用可用的最强编码/调制方案来发送每个块。
