full_form: Binary Phase Shift Keying
context: S-E-DPDCHs are only present when the UE transmits two transport blocks. When present, the number of S-E-DPDCHs is always 4. The maximum amount of puncturing that can be applied is - 1-PLnon-max if the modulation scheme is less than the maximum allowed by the UE capability and restrictions imposed by UTRAN. - 1-PLmod_switch if the modulation scheme is BPSK and the usage of 4PAM is allowed by the UE capability and restrictions imposed by UTRAN. - 1-PLmod_switch_2 if the modulation scheme is 4PAM and the usage of 8PAM is allowed by the UE capability and restrictions imposed by UTRAN. - 1-PLmax if the modulation scheme equals to the maximum allowed by the UE capability and restrictions imposed by UTRAN. The number of available bits per TTI of one S-E-DPDCH for all possible spreading factors and modulation schemes is denoted by N4, N2, M4, M2, L4 and L2, where the index refers to the spreading factor. N refers to BPSK modulation, M to 4PAM modulation and L to 8PAM modulation. The possible
description: Binary Phase Shift Keying (BPSK) is a modulation technique used in the uplink E-DCH reference measurement channel for DC-HSUPA tests. It is specified in subclause A.2.6 of the 3GPP TS 25.101 document and is used to verify the UE maximum output power, additional spectrum emission mask, and additional ACLR requirement for DC-HSUPA.
explanation: BPSK is classified as a Technology because it is a specific modulation technique used in telecommunications standards (DC-HSUPA) and defined within technical documents (3GPP TS 25.101). Its purpose is to ensure compliance with specific performance requirements.
