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.

Description
本申请要求于2015年11月06日提交中国专利局、申请号为201510752268.5、发明名称为“一种子帧调度方法及设备”以及2016年05月27日提交中国专利局、申请号为201610363801.3、发明名称为“一种子帧调度方法及设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明的实施例涉及通信领域,尤其涉及一种子帧调度方法及设备。
第三代合作伙伴计划(英文缩写:3GPP,英文全称:The 3rd Generation Partnership Project)长期演进(英文缩写:LTE,英文全称:Long Term Evolution)***中,包含时分双工(英文缩写:TDD,英文全称:Time Division Duplexing)和频分双工(英文缩写:FDD,英文全称:Frequency Division Duplexing)两种工作模式。LTE TDD模式下上下行工作于同一频率,彼此之间采用一定保护时间予以分离,并且该模式下不需要分配对称频段的频率,可以充分利用零散的频谱资源。该工作模式下通过调整上下行时隙配比,可以灵活地支持对称和不对称业务数据传输。
LTE***中在TDD模式下,存在上行链路(英文缩写:UL,英文全称:up link)的子帧数多于下行链路(英文缩写:DL,英文全称:down link)子帧数的情况,例如:UL/DL配比为6:4。此时,存在通过一个DL下行子帧中发送的DCI调度两个UL上行子帧的情况。示例性的,当前帧结构中存在#0-9子帧共10个子帧,其中#0、#1、#5和#6子帧为下行子帧可以发送上行DCI调度上行子帧,其余为上行子帧。当前的调度方案是采用当前下行子帧加扰码k的方式调度上行子帧,即如果当前下行子帧为n,那么,他将调度n+k的上行子帧。由于下行子帧的数量少于上行子帧,显然,不能完全调度所有的上行子帧。因此,LTE中在上行DCI中增加了
UL INDEX(标识)域,INDEX域由两bit表示,分别为MSB(英文全称:Most Significant Bit,中文:最高加权位)和LSB(英文全称:least significant bit,中文:最低加权位)。LTE协议中规定的调度规则如下:
当MSB为1,那么,DCI调度的是n+k的上行子帧;
当LSB为1,那么,DCI调度的是n+7的上行子帧;
如果MSB和LSB均被设置为1时,那么,则同时调度n+k和n+7的上行子帧。
根据上述规定,示例性的,TDD中配置DL子帧0对应的k为4,DL子帧1对应的k为6时,DL子帧0可以调度UL子帧4和7,DL子帧1可以调度UL子帧7和8。
LTE中DCI中指示调度上行子帧的新传或者重传的指示NDI域只有1bit,如果此时UL子帧4和UL子帧8的反馈结果均为NACK(不确定),而UL子帧7的反馈结果为ACK(确定),那么,此时,无法同时进行调度;或者,子帧7也按NACK进行反馈,会浪费资源,降低吞吐量。因此,上述方法只适应于特定的UL/DL时隙配比。

101、第一设备向第二设备发送至少一个第一类子帧。
至少一个第一类子帧中配置有该至少一个子帧所属帧结构中预设数量的第二类子帧的调度信息,其中该预设数量可以预配置为任意

本发明的实施例提供的上行调度方法,第一设备首先向第二设备发送至少一个第一类子帧,其只该至少一个第一类子帧中配置有该至少一个子帧所属帧结构中预设数量的第二类子帧的调度信息;第二设备接收第一设备发送至少一个第一类子帧并根据调度信息向第一设备发送第二类子帧,从而实现了帧结构中预设数量的第二类子帧的调度,避免了第二类子帧和第一类子帧的配比方案对子帧调度的影响,能够提高子帧调度对UL/DL时隙配比的兼容性。
本发明的另一实施例提供一种子帧调度方法,参照图3所示,包括如下步骤:
201、第一设备向第二设备发送至少一个第一类子帧。

以第一类子帧和第二类子帧均为下行子帧时的下行子帧调度为例,参照图5所示,提供一种对7个下行子帧进行下行调度的示例。对于调度信息,下行子帧的标识位图(DL INDEX位图)包含7个1比特位,其中每个1比特用于指示对应的下行子帧是否被调度,示例性的当某个1比特为指示为1时,则表示调度相应的下行子帧;否则,如果为0时,则表示该下行子帧未被调度。NDI域位图中包
含7个1比特位,1比特用于指示对应的下行子帧执行第一类操作,或者所述NDI域位图中的1比特用于指示对应的下行子帧执行第二类操作,示例性的,当NDI域位图中某个1比特位为1时,那么,对应NDI域位图中相应的1比特位生效用于指示对应的下行子帧执行第一类操作,否则,该1比特位的值不生效,用于指示对应的下行子帧执行第二类操作。其中第一类操作为新传操作,第二类操作为重传操作;或者第一类操作为重传操作,第二类操作为新传操作,具体的第二设备为根据NDI域位图中某个1比特位判断执行第一类操作或第二类操作,示例性的可以第二设备根据NDI域位图中某个1比特位的值执行翻转操作。当然第一类子帧和第二类子帧也可以使用S1子帧不再赘述。
可选的,调度信息为DCI(英文全称:Downlink control information,中文:下行控制信息)。
202、第二设备接收第一设备发送至少一个第一类子帧。
203、第二设备根据该调度信息向第一设备发送第二类子帧。
