6. The PUCCH-based feedback information transmitting apparatus according to claim 5, wherein the second determining unit is specifically configured to:
if the target PUCCH format is PUCCH format 0, determining the last 4 continuous SC-FDMA symbols in the subframe 4 as the target SC-FDMA symbols;
if the target PUCCH format is PUCCH format 3, determining the last 5 continuous SC-FDMA symbols in the subframe 4; and/or the first 4 consecutive SC-FDMA symbols in subframe 4 are the target SC-FDMA symbols.
7. The PUCCH-based feedback information transmitting apparatus according to claim 6, further specifically configured to:
if the target PUCCH format is PUCCH format 0, determining a second SC-FDMA symbol and a third SC-FDMA symbol in the target SC-FDMA symbols as pilot frequency;
if the target PUCCH format is PUCCH format 3, determining that a second SC-FDMA symbol and a third SC-FDMA symbol in the last 5 continuous SC-FDMA symbols in subframe 4 are pilot frequencies; and/or the second SC-FDMA symbol and the third SC-FDMA symbol of the first 4 consecutive SC-FDMA symbols in subframe 4 are pilots.
8. The PUCCH-based feedback information transmitting apparatus according to claim 6, further specifically configured to:
if the target PUCCH format is PUCCH format 3, it is determined that the last 5 consecutive SC-FDMA symbols in subframe 4 and the first 4 consecutive SC-FDMA symbols in subframe 4 respectively constitute two PUCCH symbol groups.
9. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the steps of the method according to any one of claims 1 to 4 when the computer program is executed.
10. A non-transitory computer readable storage medium, on which a computer program is stored, characterized in that the computer program, when being executed by a processor, implements the steps of the method according to any one of claims 1 to 4.
