  • symmetric and asymmetric service data transmission can be flexibly supported by adjusting the uplink and downlink time slot ratio.

  • the UL/DL ratio is 6:4.
  • the current scheduling scheme is to schedule an uplink subframe by using the current downlink subframe scrambling code k. That is, if the current downlink subframe is n, then it will schedule an uplink subframe of n+k. Since the number of downlink subframes is less than the uplink subframe, it is obvious that all uplink subframes cannot be completely scheduled. Therefore, LTE has been added to the uplink DCI.

  • the scheduling rules specified in the LTE protocol are as follows:
  • the DCI schedules an uplink subframe of n+k
  • the DCI schedules an uplink subframe of n+7;
  • both the MSB and the LSB are set to 1, then the uplink subframes of n+k and n+7 are simultaneously scheduled.
  • the k corresponding to the DL subframe 0 in the TDD is 4, and the k corresponding to the DL subframe 1 is 6, the DL subframe 0 can schedule the UL subframes 4 and 7, and the DL subframe 1 can UL subframes 7 and 8 are scheduled.
  • the indication that the new transmission or the retransmission of the uplink subframe is scheduled in the DCI in the LTE is only 1 bit. If the feedback result of the UL subframe 4 and the UL subframe 8 is NACK (unsure), the UL subframe 7 is The feedback result is ACK (determination), then, at this time, scheduling cannot be performed at the same time; or subframe 7 is also fed back by NACK, which wastes resources and reduces throughput.
