full_form: Single Carrier
context: For and Ï/2-BPSK modulation only 2-of-3 adjacent subcarriers are selected as described in 5.5.2.1A.2. The time-continuous signal in SC-FDMA symbol in an uplink slot is defined by for where , , is given by Table 5.6-1, and and are respectively the modulation value for subcarrier index and for symbol , and the values of used on and are respectively obtained by subtracting from the resulting set of allocated subcarriers as described in Table 8.1.6-1 of [4], and represents the lower subcarrier index among the selected subcarriers and is the subcarrier index adjacent to it. The phase rotation is given by where is the number of transport blocks defined in clause 8.0 of TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4]. If >1 and interleaving between codewords is applied according to clause 8.0 of TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4], then the symbol counter is reset at the start of the first PUSCH codeword transmission and incremented for each symbol during the transmission of the PUSCH codewords. For other cases, the symbol counter is reset at the start of each PUSCH codeword transmission and incremented for each symbol during the transmission of the PUSCH codeword. The SC-FDMA symbols in a slot shall be transmitted in increasing order of , starting with , where SC-FDMA symbol starts at time within the slot.
description: Single Carrier (SC) refers to a transmission mode in Evolved Universal Terrestrial Radio Access (E-UTRA) where data is transmitted on a single carrier frequency, as opposed to multi-carrier transmissions. In the context of SC-FDMA (Single Carrier Frequency Division Multiple Access), it defines how symbols are modulated and transmitted within an uplink slot, including specifics on subcarrier selection, modulation schemes like Ï/2-BPSK, and phase rotation. This technology is crucial for efficient data transmission in 4G LTE networks.
explanation: SC is classified under the Technology category because it pertains to a specific method of transmitting data over radio access networks, adhering to the standards set by 3GPP for E-UTRA. The details provided in the context about modulation schemes, subcarrier selection, and transmission protocols further solidify its categorization as a technological aspect within telecommunications.
