Definitions
- Embodiments of the present invention relate to the field of communications, and in particular, to a subframe scheduling method and device.
- the 3rd Generation Partnership Project (English abbreviation: 3GPP, English full name: The 3rd Generation Partnership Project) Long-term evolution (English abbreviation: LTE, English full name: Long Term Evolution) system, including time division duplex (English abbreviation: TDD, English Full name: Time Division Duplexing and Frequency Division Duplex (English abbreviation: FDD, English full name: Frequency Division Duplexing) two working modes.
- TDD Time Division Duplex
- FDD Frequency Division Duplex
- LTE TDD mode the uplink and downlink work at the same frequency, and are separated by a certain guard time.
- the frequency of the symmetric frequency band does not need to be allocated, and the scattered spectrum resources can be fully utilized.
- symmetric and asymmetric service data transmission can be flexibly supported by adjusting the uplink and downlink time slot ratio.
- the number of subframes in the uplink (English abbreviation: UL, English full name: up link) is more than the number of subframes in the downlink (English abbreviation: DL, English full name: down link).
- 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.
- UL INDEX (identification) field, INDEX field is represented by two bits, which are MSB (English full name: Most Significant Bit, Chinese: highest weighted bit) and LSB (English full name: least significant bit, Chinese: lowest weighted bit).
- 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. Therefore, the above method is only adapted to a specific UL/DL slot ratio.
