- Single slot scheduling the PDCCH is received in one slot, and the scheduling information indicates the sending and receiving of PDSCH/PUSCH for one slot.
- Semi-static scheduling Radio Resource Control (RRC) semi-statically configures the time-frequency resources for scheduling.
- the terminal receives the PDCCH at the activated PDCCH Mobile Originating (MO), and one PDCCH indicates scheduling information for multiple slots.
- RRC Radio Resource Control
- the RV version has RRC semi-static configuration
- the activation field of PDCCH MO is set to zero for hybrid automatic retransmission request (Hybrid auto retransmission query-identifier, HARQ-ID)
- NDI is set to zero to realize the activation of PDCCH.
- slot-aggregation scheduling the time domain resources are configured by RRC, and the frequency domain resources are configured by PDCCH.
- the scheduling information of PDCCH is used for the scheduling of the next multiple slots.
- LTE scheduling can support multi-subframe scheduling.
- the background proposed by the multi-subframe scheduling is based on eLAA UL PUSCH transmission, that is, the corresponding DCI format is 0B/4B.
- eLAA's multi-subframe scheduling all scheduling information except NDI and RV is shared by multiple subframes; DCI format 0B/4B NDI and RV support multiple subframe information by extending bit bits .
- NR's semi-static scheduling has poor scheduling flexibility. Multiple slots can only use the same time-frequency scheduling information and cannot adapt to changes in user services and channels;
- NR's slot-aggregation also has the above problems.
- multiple slots send the same data information.
- the resource utilization rate is low;
- the multi-subframe scheduling of eLAA of LTE can first only be applied to the scheduling of PUSCH; secondly, the DCI used to indicate the multi-subframe scheduling needs to be newly added, which will increase the NR. PDCCH DCI standardization is difficult.
- NR considers supporting multi-subframe scheduling, and considers directly extending the LTE eLAA solution, that is, in the existing NR DCI, the NDI and RV indications add bit bits, which are used to configure multi-slot scheduling information. For other scheduling information , Multiple slots can be reused, but there will be the following problems:
- the method of directly increasing the bit number will bring greater difficulty to standardization, because it is necessary to add a new DCI format or increase the bit number of the existing DCI format, which does not match the principles of NR DCI design.
- an embodiment of the present disclosure proposes a multi-time unit scheduling scheme, and its main ideas are:
- a network-side device such as a base station
- the number of the DCI is not less than the number of multiple time unit information for scheduling data transmission.
- the base station may send to the terminal through a signal/channel that carries the first information for scheduling data transmission.
- the signal of the first information for scheduling data transmission may be indicated based on a search space (Search) (SS) group; it may be a group-common (group public) DCI indication; it may be a group-common DCI indication for scheduling data transmission

- TDRA Time Domain Resource Allocation
- the terminal may detect multiple DCIs that schedule data transmission according to the instruction information, and obtain detailed scheduling information for each time unit.
- the base station can configure multi-slot scheduling, and the number of specific scheduled slots can be notified to the terminal. If the base station uses multiple DCIs to schedule multiple time units for transmission, the terminal will detect multiple DCI information according to the number of slots, so that PDSCH reception or PUSCH transmission of multiple slots can be performed.

相关申请的交叉引用
本申请主张在2018年12月20日在中国提交的中国专利申请号No.201811578135.0的优先权,其全部内容通过引用包含于此。
本公开实施例涉及通信技术领域,尤其涉及一种信息处理方法、装置、设备及计算机可读存储介质。
随着无线通信***的发展,终端类型和业务类型多样化,终端省电、节约网络资源和满足各种业务类型的需求并存。其中,对跟在物理下行控制信道(Physical downlink control channel,PDCCH)后面的子帧中,没有调度数据的PDCCH监测的功耗占比在某些情况下甚至达到50%以上。通过降低这部分功耗,可以大大提升终端的节能效果。进一步的,在对PDCCH后面有数据调度的PDCCH的监测功耗上,如果可以进一步降低终端对这些PDCCH的检测次数,则可以进一步降低检测功耗。基于此,基站可以采用多slot(时隙)调度,即PDCCH仅检测一个slot,可以调度多个slot的PDSCH/PUSCH的传输,终端通过跳过后续的多个物理下行共享信道(Physical downlink shared channel,PDSCH)/物理上行共享信道(Physical uplink shared channel,PUSCH)的传输slot上的PDCCH的监测,实现终端功耗的降低。
基于以上分析,相关技术的PDCCH的调度,是基于单slot调度的。在超高可靠低时延通信(Ultra reliability low latency communication,URLLC)应用中,支持时隙聚合(slot-aggregation),其主要原理是提高URLLC的传输可靠性,从而聚合的多个slot传输的是相同的信息,且调度信息是半静态配置的。显然,这种方式对于一般增强移动宽带(Enhance Mobile Broadband,eMBB)场景是不适用的。因为slot-aggregation失去了调度的灵活性,同时也不能依据信道和业务的时变特性及时调整调度结果。
进一步的,基站考虑支持多slot调度,在相关技术的长期演进(Long Term Evolution,LTE)针对上行链路(UpLink,UL)增强的授权频谱辅助连接(Enhanced Licensed assistant access,eLAA),增加了下行控制信息(Downlink control information,DCI)format(格式)0B/4B的配置。在所述两种format中,新数据指示(New data indication,NDI),冗余版本(redundancy version,RV)的指示,增加bit(比特)位,用于配置多子帧调度的信息。对于其他的调度信息,可以多子帧复用。考虑新无线(New Radio,NR),可以复用LTE的多子帧调度机制,将多slot的信息通过增加bit位的形式支持多slot调度。但是,直接增加bit位的方式,需要增加新的DCI format或是增加已有DCI format的bit位,这和NR DCI设计的原则是不匹配的。
因此,如何在相关技术的NR DCI的设计下实现多slot调度以降低终端的能量消耗,是需要解决的技术问题。

相关技术中NR的调度主要有三种方式:一是单slot调度,二是半静态调度,三是slot-aggregation调度。单slot调度,PDCCH在一个slot接收,调度信息中,指示一个slot的PDSCH/PUSCH的发送和接收。半静态调度,无线资源控制(Radio Resource Control,RRC)半静态配置调度的时频资源,终端在激活的PDCCH移动发起(Mobile Originating,MO)处接收PDCCH,一个PDCCH指示多个slot的调度信息,其中,RV版本,有RRC半静态配置,PDCCH MO的激活字段为混合自动重传请求标识(Hybrid auto retransmission query–identifier,HARQ-ID)置零,以及NDI置零,来实现PDCCH的激活。slot-aggregation调度,时域资源是RRC配置的,频域资源是PDCCH配置的,PDCCH的调度信息用于接下来的多个slot的调度。
除此之外,LTE的调度可以支持多子帧调度。所述多子帧调度提出的背景是基于eLAA UL PUSCH传输,即对应的DCI format是0B/4B。在eLAA的多子帧调度中,除了NDI,RV之外,其他所有的调度信息,都是多个子帧共用的;DCI format 0B/4B的NDI,RV通过扩展bit位来支持多个子帧的信息。
基于以上分析,相关技术的多子帧或多slot调度,存在以下问题:
NR的半静态调度,调度灵活性差,多个slot仅能使用相同的时频调度信息,不能适应用户业务和信道的变化;
NR的slot-aggregation,同样存在上述问题。除此之外,多个slot发送的为相同的数据信息,对于eMBB场景来说,使用资源利用率低;
LTE的eLAA的多子帧调度,首先仅能应用于PUSCH的调度;其次,用于指示多子帧调度的DCI需要新增加,会增加NR的PDCCH DCI标准化难度大。
进一步的,NR考虑支持多子帧调度,考虑直接扩展LTE的eLAA的方案,即在已有NR DCI中NDI,RV的指示增加bit位,用于配置多slot调度的信息,对于其他的调度信息,可以多slot复用,但是会存在以下问题:
直接增加bit位的方式,会给标准化带来较大的难度,因为需要增加新的DCI format或是增加已有DCI format的bit位,这和NR DCI设计的原则是不匹配的。
为解决上述问题,本公开实施例提出了一种多时间单元调度的方案,其主要思想是:
当基站配置为调度数据传输的多时间单元时,网络侧设备(如基站)可以在一个时间单元上发送至少一个DCI,用于调度数据传输的至少一个时间单元的信息(此文称为第一信息)。其中,所述DCI的个数,不小于调度数据传输的多个时间单元信息的个数。具体的,调度数据传输的多个时间单元的个数,基站可以通过承载调度数据传输的第一信息的信号/信道发送给终端。其中,所述调度数据传输的第一信息的信号可以是基于搜索空间(Search space,SS)分组指示的;可以是group-common(小组公共)DCI指示;可以是group-common DCI指示调度数据传输的第一信息,UE-specific(UE特定的)是否激活第一信息;可以是power saving signal(节能信号)指示的;可以是加扰的序列指示的;可以是frozen bit(冻结比特位)指示的;还可以是通过时域资源分配(Time Domain Resource Allocation,TDRA)指示的等等。
终端在收到所述指示信息后,可以根据指示信息检测调度数据传输的多个DCI,获取每个时间单元的详细调度信息。
通过所述方法,基站可以配置多slot调度,具体的调度的slot的数目可以通知给终端。基站如果采用多个DCI调度传输的多个时间单元,那么终端将按照slot数目检测多个DCI信息,从而可以进行多个slot的PDSCH的接收或PUSCH的发送。
下面将结合附图和实施例,对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开,但不用来限制本公开的范围。
如图1所示,本公开实施例的信息处理方法,应用于网络侧设备,包括:

之后,网络侧设备可根据第一信息和调度信息进行数据处理,例如发送PDSCH,或接收PUSCH。
在本公开实施例中,网络侧设备可以在一个时间单元发送多个DCI,调度后续的多个时间单元中数据的接收或发送,因此,通过这种方式终端无需检测多个时间单元,从而降低了终端的能量消耗。

当所述UE-specific DCI为一个时,则UE-specific DCI中部分调度指示信息,需要扩展bit位,支持多个时间单元的调度信息;例如,NDI指示位、RV指示位。所述UE-specific DCI大于一个时,则一个UE-specific DCI可以调度一个调度数据传输的时间单元的调度信息,所述M个调度数据传输的时间单元的调度信息,需要至少M个UE-specific DCI的指示。
相应的,终端接收UE-specific DCI。
步骤33、基站发送下行数据/信息,或基站接收上行数据/信息。具体的:

那么,在此实施例中,终端获取第一DCI指示的第一信息,如果第一信息被激活,那么,终端根据该第一信息和调度信息进行数据处理。
具体的,如果第二信息指示第一信息为激活,则终端将按照第一DCI指示的调度数据传输的时间单元信息的个数发送上行数据/信息或接收下行数据/信息。
如果第二信息指示调度数据传输的第一信息为非激活,则终端可以不按照第一DCI指示的调度数据传输的时间单元信息的个数发送上行数据/信息或接收下行数据/信息。那么,此时,终端可以按照高层信令配置的调度数据传输的时间单元信息发送上行数据/信息或接收下行数据/信息,也可以按照单个时间单元调度发送上行数据/信息或接收下行数据/信息,或者终端还可以按照和基站约定好的调度数据传输的时间发送上行数据/信息或接收下行数据/信息。

所述调度数据传输的第一信息,可以通过polar(极值)码中frozen bit(冻结比特位)指示。所述frozen bit,为polar序列的一些填零bit位,如果用frozen bit位指示调度数据传输的第一信息,则可以定义不同的bit映射规则。
例如,0011,代表调度数据传输的三个时间单元信息,则0011,可以映射到所述frozen bit位上。
所述映射原则,可以是基站和终端约定好的,可以是基站通知给终端的。

当所述UE-specific DCI为一个时,则UE-specific DCI中部分调度指示信息,需要扩展bit位,支持多个时间单元的调度信息;例如,NDI指示位、RV指示位。当所述UE-specific DCI大于一个时,则一个UE-specific DCI可以调度一个调度数据传输时间单元的调度信息,所述M个调度数据传输的时间单元的调度信息,需要至少M个UE-specific DCI的指示。1
相应的,终端接收DCI。
步骤93、基站发送下行数据/信息,或基站接收上行数据/信息。

解析TDRA bitmap或TDRA index或TDRA bit位所指示的第一信息,并根据该第一信息和UE-specific DCI的指示进行数据处理。
基于以上分析,相比于相关技术或类似技术,本公开实施例具有如下优点:
相对于NR的半静态的指示的多个slot的个数的信息,本公开实施例可以动态配置slot个数,调度灵活性更好;更能适应用户业务和信道的变化。相对于NR的slot-aggregation,多个slot调度信息由多个DCI分别指示,大大提高了资源利用率。相对比LTE的eLAA的多子帧调度,本公开实施例不仅可以应用于PUSCH调度,也可以应用于PDSCH调度;其次,本公开实施例可以不改变相关技术的用于调度的DCI个数,降低了PDCCH DCI标准化复杂度。
