Before TTI-B function, terminal sends upstream data with TTI-B mode, since base station receives data using dual decoding mode, but with
TTI-B mode can solve pair, and total solution is wrong in the normal mode.
In step 390, base station returns to ACK or NACK response to terminal.
In non-TTI-B state, i.e., after terminal configures and deactivates TTI-B function, terminal has data packet to send, meeting
It sends in the normal mode, since base station is received using dual decoding, mistake is solved always with TTI-B mode, can be solved in the normal mode pair, once
