Description

Subframe scheduling method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a subframe scheduling method and apparatus.

Background

In The third generation partnership Project (3 GPP, full name: The 3rd generation partnership Project) Long Term Evolution (LTE, full name: Long Term Evolution) system, two operating modes, Time Division duplex (TDD, full name: Time Division duplex) and Frequency Division duplex (FDD, full name: Frequency Division duplex) are included. The uplink and the downlink work in the same frequency in the LTE TDD mode, and are separated by adopting a certain protection time, and the frequencies of symmetrical frequency bands are not required to be distributed in the LTE TDD mode, so that scattered frequency spectrum resources can be fully utilized. By adjusting the ratio of uplink and downlink time slots in the working mode, the method can flexibly support the transmission of symmetric and asymmetric service data.

In the TDD mode in the LTE system, there are cases where the number of subframes in the Uplink (UL) is greater than the number of subframes in the Downlink (DL), for example: the UL/DL ratio is 6: 4. At this time, two UL uplink subframes may be scheduled by DCI transmitted in one DL downlink subframe. Illustratively, there are 10 subframes in the current frame structure, where the subframes #0 to # 9 are downlink subframes and uplink subframes for transmitting uplink DCI scheduling uplink subframes, and the remaining subframes are uplink subframes. The current scheduling scheme is to schedule the uplink sub-frame by scrambling k with the current downlink sub-frame, i.e. if the current downlink sub-frame is n, then he will schedule the uplink sub-frame of n + k. Since the number of downlink subframes is less than that of uplink subframes, it is apparent that all uplink subframes cannot be completely scheduled. Therefore, in LTE, an UL INDEX field is added to the uplink DCI, and the INDEX field is represented by two bits, namely MSB (Most Significant Bit, Chinese: the highest weighted Bit) and LSB (least Significant Bit, Chinese: the lowest weighted Bit). The scheduling rules specified in the LTE protocol are as follows:

when the MSB is 1, the DCI schedules an n + k uplink subframe;

when LSB is 1, then DCI schedules an uplink subframe of n + 7;

if both MSB and LSB are set to 1, then uplink subframes of n + k and n +7 are scheduled simultaneously.

According to the above specification, for example, when k corresponding to DL subframe 0 is 4 and k corresponding to DL subframe 1 is 6 in TDD, DL subframe 0 may schedule UL subframes 4 and 7, and DL subframe 1 may schedule UL subframes 7 and 8.

In the LTE, an indication NDI domain indicating new transmission or retransmission of an uplink subframe is scheduled in DCI only has 1bit, and if the feedback results of a UL subframe 4 and a UL subframe 8 are both NACK (uncertain) and the feedback result of a UL subframe 7 is ACK (confirmed), then scheduling can not be carried out at the same time; alternatively, subframe 7 is also fed back in NACK, which wastes resources and reduces throughput. Therefore, the above method is only adapted to a specific UL/DL slot ratio.
