WLC09-4: System Level Performance of HRPD Revision B

Revision B of the high rate packet data standard defines several new transmission formats for forward traffic channel transmission. The new transmission formats provide higher order modulation, an increased quantization in nominal data rate, and more opportunity for hybrid automatic repeat request gain. Consequently, the access terminal has many more choices when mapping a measured pilot signal-to-noise ratio to a requested transmission format. Ultimately, the new transmission formats result in a more efficient use of system resources leading to increased system performance. In this paper, we show that system level performance is increased by 25% for one receive antenna and 28% for two receive antennas as a result of the new transmission formats. We further show the distribution of selected transmission formats.
