name: SF
full_form: Spreading Factor
context: The combinations of BPSK and 16QAM reference measurement channels in Table A.10AC shall be used for verifying the UE maximum output power for DC-HSUPA, additional Spectrum emission mask for DC-HSUPA, and additional ACLR requirement for DC-HSUPA. The entry BPSK in Table A.10AC refers to the UL E-DCH reference measurement channel for DC-HSUPA using BPSK modulation, specified in subclause A.2.6, and the entry 16QAM refers to the UL E-DCH reference measurement channel for DC-HSUPA using 16QAM modulation, specified in subclause A.2.7. The power imbalance in subclause A.2.6 and A.2.7 have been adjusted as shown in Table A.10AC. Table A.10AC: Settings for DC-HSUPA reference measurement channels for UE maximum output power, spectrum emission mask and ACLR requirements
description: The Spreading Factor (SF) is a parameter that determines the number of chips used for spreading in the Physical Random Access Channel (PRACH) and Enhanced Random Access Channel (E-RUCCH). It affects the code resource allocation and collision avoidance between PRACH and E-RUCCH.
explanation: The context describes how the Spreading Factor influences the behavior of PRACH and E-RUCCH, including code resource assignment, collision avoidance, and acknowledgement transmission. This indicates that SF is a parameter that controls specific aspects of random access procedures in the 3GPP specification.
