context: performance than single-sided configuration. To estimate the corresponding ACIR values, it can be noted when comparing figure 35B and 35C with figure 35D that the ACS values are about 20 dB lower than the ACLR values. This means that ACS dominates ACIR and while ACLR still has an effect on the results, it is not by much. Thus, the lowest ACIR values occur when GSM carrier spacing is small. Table 31A shows ACIR for 600 kHz GSM carrier separation. Table 31A: ACIR performance for GSM carriers allocated adjacent to UMTS channel. Smallest carrier separation between GSM and UMTS 2.8 MHz. 600 kHz GSM carrier spacing. It can be seen in the table that when replacing a SCBTS with a MCBTS, the impact on ACIR is very small, class 1 less than 0.01 dB and class 2 less than 0.02 dB. If the more realistic IM emission levels are used, the degradation is even smaller. The degradation is insignificant in the double-sided scenario due to low combined ACS. Some of the carrier configurations, e.g. 2x2
description: Dual Cell HSUPA (DC-HSUPA) is a technology enhancement in the High-Speed Uplink Packet Access (HSUPA) protocol. It allows for simultaneous transmission on two cells to improve uplink data transfer rates and overall network performance by enabling User Equipment (UE) to utilize multiple cells for uplink transmissions.
explanation: The text describes DC-HSUPA as a technology enhancement within the HSUPA protocol, focusing on its technical aspects like improved uplink data rates and utilization of multiple cells. This points towards it being a technological advancement.
