Description

反馈信息处理方法及通信装置
本申请要求于2019年9月30日提交中国专利局、申请号为201910944745.6、申请名称为“反馈信息处理方法及通信装置”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。
技术领域
本申请涉及通信技术领域，尤其涉及一种反馈信息处理方法及通信装置。
背景技术
在数据传输过程中，为了保证数据传输的可靠性，终端需要对基站发送的数据，反馈混合自动重传请求(hybrid automatic repeat request,HARQ)-确认(ACK)信息，以使得基站确认是否需要重传该数据。为了获得该HARQ-ACK信息，终端需要完成以下操作：信道估计；根据信道估计的结果解调数据；基于解调结果获得反馈信息并进行上行的调制编码。而在重复传输模式下，终端需要完成多次重复传输的下行共享信道的处理，因此，如何为终端分配反馈时域资源，以保证终端设备处理完上述操作的同时还能够及时上报反馈信息，对于数据传输的可靠性和时效性来说极其重要。
发明内容
本申请提供了一种反馈信息处理方法及通信装置，有利于保证数据传输的可靠性和时效性。
第一方面，本申请提供一种反馈信息处理方法。该反馈信息处理方法中，网络设备可根据重复传输下行共享信道的次数m 1，确定最小时间间隔T，m 1大于或等于2；并基于该最小时间间隔T，确定反馈时域资源，以使终端设备上报下行共享信道的反馈信息。其中，最小时间间隔T是下行共享信道的重复传输结束时刻到所述反馈信息的反馈起始时刻之间的最小时间间隔。
也就是说，该最小时间间隔是终端设备完成重复传输的下行共享信道的相关处理后，能够上报反馈信息的最小时间间隔。可见，本申请实施例能够基于重复传输模式下的最小时间间隔来确定反馈时域资源，有利于保证终端设备上报有效的反馈信息的同时，实现尽快反馈，从而有利于保证数据传输的可靠性和时效性。
在一种实施方式中，网络设备根据重复传输下行共享信道的次数m 1，确定最小时间间隔T。其中，m 1的取值为大于等于1的整数。
另一种可能的设计中，重复传输下行共享信道的次数m2大于等于m 1的两倍时，重复传输下行共享信道的次数m 1对应的最小时间间隔T1不大于重复传输下行共享信道的次数m2对应的最小时间间隔T2。例如，非重复传输的下行共享信道的最小时间间隔为T1，两次重复传输的下行共享信道的最小时间间隔为T2，则T2小于T1。
在又一种可能的设计中，重复传输下行共享信道的次数m 1大于2时，最小时间间隔T等于T1+Y，其中，Y大于或等于(m 1/2)*X，且小于(m 1-1)*T1。X为重复传输下行共享信道 的次数m 1等于2时的最小时间间隔与重复传输下行共享信道的次数m 1等于1时的最小时间间隔T1之间的差值。
在又一种可能的设计中，上述各设计的前提条件是重复传输m 1次下行共享信道所占的总的时域资源不变。在另一种实施方式中，网络设备根据重复传输的次数m 1和重复传输下行共享信道一次所占的时域资源包括的时间单元的数量，确定最小时间间隔T。
一种可能的设计中，重复传输下行共享信道一次所占的时域资源包括的时间单元的数量越小，最小时间间隔T越大。
另一种可能的设计中，当重复传输下行共享信道的次数m 1大于1时，重复传输一次所占的时域资源包括的时间单元的数量越大，最小时间间隔T越小。例如但不限于，重复传输的次数m 1等于2且重复传输一次所占的时域资源包括的时间单元的数量等于2个符号时，最小时间间隔T等于T1+X。重复传输的次数m 1等于2且重复传输一次所占的时域资源包括的时间单元的数量等于4个符号时，最小时间间隔T等于T1+Z。其中，Z小于X。
在又一种可能的设计中，重复传输下行共享信道的次数m 1等于1时，最小时间间隔为T1。若重复传输下行共享信道的次数m 1大于1，且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量大于或等于第一预设值时，最小时间间隔等于T1；若重复传输下行共享信道的次数m 1大于1，且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量小于第一预设值时，最小时间间隔大于T1。可选的，该第一预设值可等于4。
在又一种实施方式中，网络设备根据重复传输下行共享信道的次数m 1、重复传输所述下行共享信道一次所占的时域资源包括的时间单元的数量以及重复传输所述下行共享信道两次分别所占的时域资源之间的时间间隔，确定最小时间间隔T。其中，两次重复传输之间的时间间隔不承载所述下行共享信道。
一种可能的设计中，重复传输所述下行共享信道两次分别所占的时域资源之间的时间间隔越大，最小时间间隔越小。
在另一种可能的设计中，若重复传输下行共享信道的次数m 1大于1，且重复传输PDSCH两次分别所占的时域资源之间的时间间隔大于或等于第四预设值时，最小时间间隔等于T1；若重复传输下行共享信道的次数m 1大于1，且重复传输PDSCH两次分别所占的时域资源之间的时间间隔小于第四预设值时，最小时间间隔大于T1。可选的，该第四预设值可等于2。
在又一种实施方式中，最小时间间隔T是由一个或多个处理时延相加获得的，所述一个或多个处理时延包括第一处理时延d1.1。在所述第一时域资源包括的时间单元数量不同的情况下，所述第一处理时延d1.1的取值不同。第一时域资源为重复传输m 1次下行共享信道所占的总的时域资源。
在一种可能的设计中，第一时域资源还包括两次重复传输之间的时间间隔。也就是说，第一时域资源是指第一次重复传输的起始时域位置到最后一次重复传输的结束时域位置的时域资源。
在另一种可能的设计中，第一时域资源不包括两次重复传输之间的时间间隔。也就是说，第一时域资源均用于承载所述下行共享信道。
在一种实施方式中，所述第一时域资源包括K4个时间单元时，或者，第一时域资源 中时间单元的数量大于K4时，所述第一处理时延d1.1等于零；或者，所述第一时域资源包括K3个时间单元时，或者第一时域资源中时间单元的数量大于K2且小于K4时，所述第一处理时延d1.1等于预设值，所述预设值大于零。
在另一种实施方式中，网络设备根据所述第一时域资源包括的时间单元数量、所述第一时域资源与第三时域资源之间的时域位置关系，确定所述第一处理时延d1.1；其中，所述第三时域资源为下行控制信息DCI关联的控制资源集合所占的时域资源，所述DCI用于调度所述下行共享信道。
在一种可能的设计中，第一时域资源包括K2个时间单元，或者第一时域资源中时间单元的数量小于K2时：
所述第一时域资源满足第一条件时，所述第一处理时延d1.1等于所述第三时域资源包括的时间单元的数量；
所述第一时域资源不满足第一条件时，所述第一处理时延d1.1等于所述第一时域资源与所述第三时域资源之间的重叠时域资源包括的时间单元的数量，或者等于所述第一时域资源与第二时域资源之间的重叠时域资源包括的时间单元的数量。
所述第一条件为所述第一时域资源与所述第三时域资源之间具有相同的起始时域位置，且所述第三时域资源包括的时间单元的数量大于或等于所述K2。可见，该实施方式确定的最小时间间隔T考虑了终端设备基于控制资源集合检测DCI所需的时延，从而能够在保证终端设备及时上报反馈信息的同时，保证上报有效的反馈信息。
在另一种可能的设计中，所述第一时域资源包括K3个时间单元，或者第一时域资源中时间单元的数量大于K2且小于K4时，所述第一处理时延d1.1等于所述第一时域资源与所述第三时域资源之间的重叠时域资源包括的时间单元的数量；或者，

可见，该实施方式中，最小时间间隔考虑第一时域资源与第三时域资源之间的重叠情况，有利于终端设备能够基于第三时域资源解调出DCI后，基于DCI获得反馈信息。从而有利于保证终端设备上报有效的反馈信息。
在又一种实施方式中，网络设备根据所述第一时域资源包括的时间单元数量、所述第一时域资源与所述第二时域资源之间的时域位置关系，确定所述第一处理时延d1.1。第二时域资源为DCI所在的时域资源，该DCI用于调度所述下行共享信道。
在一种可能的设计中，所述第一时域资源包括K3个时间单元，所述第一处理时延d1.1等于所述第一时域资源与第二时域资源之间的重叠时域资源包括的时间单元的数量；或者，所述第一时域资源包括K2个时间单元，所述第一处理时延d1.1等于预设值+第二处理时延d，所述预设值大于零，所述第二处理时延d等于所述第一时域资源与第二时域资源之间的重叠时域资源包括的时间单元的数量。
可选的，K2等于2，K3等于4，预设值等于3。
可见，该实施方式考虑终端设备需要解调出DCI，才能进而获得反馈信息，从而有利 于保证终端设备及时上报的同时，上报有效的反馈信息。
在又一种实施方式中，网络设备根据终端设备的下行共享信道处理能力和第一时域资源包括的时间单元的数量，确定最小时间间隔T。
在一种可能的设计中，终端设备可选的下行共享信道处理能力包括下行共享信道处理能力1和下行共享信道处理能力2。该设计中，网络设备可根据终端设备具有的下行共享信道处理能力，结合上述任一或多个实施方式，确定最小时间间隔T。
在另一种可能的设计中，针对具有下行共享信道处理能力1的终端设备：

针对具有下行共享信道处理能力2的终端设备：
所述第一时域资源包括K4个时间单元时，第一处理时延d1.1等于零；
所述第一时域资源包括K3个时间单元，所述第一处理时延d1.1等于所述第一时域资源与所述第三时域资源之间的重叠时域资源包括的时间单元的数量，或者等于所述第一时域资源与所述第二时域资源之间的重叠时域资源包括的时间单元的数量；
所述第一时域资源包括K2个时间单元：所述第一时域资源满足第一条件时，所述第一处理时延d1.1等于所述第三时域资源包括的时间单元的数量；或者，所述第一时域资源不满足第一条件时，所述第一处理时延d1.1等于所述第一时域资源与所述第三时域资源之间的重叠时域资源包括的时间单元的数量，或者等于所述第一时域资源与第二时域资源之间的重叠时域资源包括的时间单元的数量；
其中，所述第一条件为所述第一时域资源与所述第三时域资源之间具有相同的起始时域位置，且所述第三时域资源包括的时间单元的数量大于或等于所述K2；
所述第二时域资源为所述DCI所在的时域资源。例如，第二时域资源为所述DCI对应的搜索空间集合所占的时域资源。可选的，在一个时隙或者子时隙内，第二时域资源的时间单元数量不大于第三时域资源的时间单元数量。
可选的，上述K2、K3、K4均为大于或等于1的整数，例如，K2等于2，K3等于4，K4等于7。预设值为大于零的值。
在上述各实施方式确定的最小时间间隔T的基础上，还可考虑第一时域资源中解调参考信号(demodulation reference signal，DMRS)与小区专用参考信号(Cell-specific RS,CRS)、控制资源集合等其他信号所占的时域资源是否冲突等，以进一步调整上述所述的最小时间间隔。也就是说，网络设备根据第一解调参考信号DMRS所占的时域位置，确定最小时间间隔T。
在一种可能的设计中，该最小时间间隔T包括第三处理时延，网络设备根据第一解调参考信号DMRS所占的时域位置确定该第三处理时延。

在一种可能的设计中，所述终端设备可接收小区专用参考信号CRS、控制资源集合CORESET、同步信号块SSB、信道状态信息参考信号CSI-RS的配置信息。
在又一种可能的设计中，第一DMRS所占的时域位置为第一时域位置时，最小时间间隔为T1；第一DMRS所占的时域位置为第二时域位置时，最小时间间隔T等于T1+第三处理时延。
其中，第一DMRS为第一时域资源中的DMRS，则该第一时域位置为每次重复传输下行共享信道所占的时域资源中的前k个符号或第n个符号；第一DMRS为除第一次重复传输外其他次重复传输的下行共享信道所占的时域资源中的DMRS，则该第一时域位置为所述其他次重复传输下行共享信道所占的时域资源中的前k个符号或第n个符号。
其中，第二时域位置包括第一信号所在的时域位置之后相邻的至少一个时间单元。第三处理时延为第一信号所占的时域资源中时间单元的数量。
在又一种实施方式中，重复传输模式所具有的DMRS可以精简，相应的，上述所述的最小时间间隔也能够在上述各实施例或各实施方式的基础上适当的进行减小。由于整个重复传输过程的信道估计的处理数量减小，因此，该实施方式有利于降低下行共享信道的处理复杂度。
在又一种实施方式中，网络设备可根据终端设备能力，进一步调整或确定最小时间间隔。比如，网络设备接收终端设备上报的能力信息；网络设备根据该能力信息确定重复传输模式下的最小时间间隔。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请的技术方案可具体应用于各种通信系统中。例如，随着通信技术的不断发展，本申请的技术方案还可用于未来网络，如5G系统，也可以称为新无线(new radio，NR)系统；或者还可用于设备到设备(device to device，D2D)系统，机器到机器(machine to machine，M2M)系统等等。
本申请的技术方案还可应用到车联网，即车与万物连接(vehicle to everything，V2X)技术(X代表任何事物)中，V2X系统中的通信方式统称为V2X通信。V2X通信针对以车辆为代表的高速设备，是未来对通信时延要求非常高的场景下应用的基础技术和关键技术，如智能汽车、自动驾驶、智能交通运输系统等场景。例如，该V2X通信包括：车辆与车辆(vehicle to vehicle，V2V)之间的通信，车辆与路边基础设施(vehicle to infrastructure，V2I)之间的通信、车辆与行人之间的通信(vehicle to pedestrian，V2P)或车辆与网络(vehicle to network，V2N)之间的通信等。V2X系统中所涉及的终端设备之间进行的通信被广泛称为侧行链路(slidelink，SL)通信。也就是说，本申请所述的终端也可以为车辆或应用于车辆中的车辆组件。
图1是本申请实施例涉及的V2X系统的示意图。该示意图包括V2V通信、V2P通信以及V2I/N通信。
如图1所示，车辆或车辆组件之间通过V2V通信。车辆或车辆组件可以将自身的车速、行驶方向、具体位置、是否踩了紧急刹车等信息广播给周围车辆，周围车辆的驾驶员通过获取该类信息，可以更好的感知视距外的交通状况，从而对危险状况做出提前预判进而做出避让；车辆或车辆组件与路侧基础设施通过V2I通信，路边基础设施，可以为车辆或车辆组件提供各类服务信息和数据网络的接入。其中，不停车收费、车内娱乐等功能都极大的提高了交通智能化。路边基础设施，例如，路侧单元(road side unit，RSU)包括两种类型：一种是终端设备类型的RSU。由于RSU分布在路边，该终端设备类型的RSU处于非移动状态，不需要考虑移动性；另一种是网络设备类型的RSU。该网络设备类型的RSU可以给与网络设备通信的车辆或车辆组件提供定时同步及资源调度。车辆或车辆组件与人通过V2P通信；车辆或车辆组件与网络通过V2N通信。其中，本申请公开的实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请公开的实施例的技术方案，并不构成对于本申请公开的实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请公开的实施例提供的技术方案对于类似的技术问题，同样适用。
请参见图2，图2为本申请实施例提供的一种通信系统的示例图。该通信系统可包括但不限于两个网络设备和一个终端设备，图2所示的设备数量和形态用于举例并不构成对 本申请实施例的限定，实际应用中可以包括两个以上的网络设备，两个或两个以上的终端设备。
本申请中，网络设备可为具有无线收发功能的设备或可设置于该设备的芯片，该网络设备包括但不限于：演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved Node B，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G、6G甚至7G系统中使用的设备，如，NR系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)，或微微基站(Picocell)，或毫微微基站(Femtocell)，或，车联网(vehicle to everything，V2X)或者智能驾驶场景中的路侧单元(road side unit，RSU)。
在一些部署中，gNB或传输点可以包括集中式单元(centralized unit，CU)和分布式单元(DU，distributed unit)等。gNB或传输点还可以包括射频单元(radio unit，RU)。CU实现gNB或传输点的部分功能，DU实现gNB或传输点的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成物理层的信息，或者，由物理层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网(core network,CN)中的网络设备，在此不做限制。
本申请公开的实施例中，用于实现网络设备的功能的装置可以是网络设备；也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中。
在本申请公开的实施例提供的技术方案中，以用于实现网络设备的功能的装置是网络设备，以网络设备是基站为例，描述本申请公开的实施例提供的技术方案。
本申请中，终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、用户代理或用户装置，可以应用于5G、6G甚至7G系统。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、前述的V2X车联网中的无线终端或无线终端类型的RSU等等。

(5)本申请公开的实施例中，至少一个还可以描述为一个或多个，多个可以是两个、三个、四个或者更多个，本申请不做限制。在本申请公开的实施例中，对于一种技术特征，通过“第一”、“第二”、“第三”、“A”、“B”、“C”和“D”等区分该种技术特征中的技术特征，该“第一”、“第二”、“第三”、“A”、“B”、“C”和“D”描述的技术特征间无先后顺序或者大小顺序。
首先对本申请中涉及的重复传输场景、相关术语以及重复传输模式下相关参数的指示方式进行阐述。
1、重复传输场景
在图2所示的通信系统中，TRP1与TRP2之间可以通过回程(backhaul)接口，直接地或者间接地，相互通信。TRP1与TRP2可以调度同一个终端，即多站协作传输场景，在时间单元之间或时间单元内重复传输同一下行共享信道多次。
本申请实施例中，在多个时频资源上重复传输的下行共享信道，分别承载的是同一个传输块(transport block,TB)，或者分别承载的是同一个数据比特(或称为数据)，或者分别承载的是同一个原始数据比特经过不同的编码后的比特。终端设备在多个时频资源上接收到的下行共享信道，可以执行软合并操作，比如将多个时频资源上接收到的下行共享信道所承载的数据进行最大似然比合并之后再执行判决。应理解的，多个时频资源上的下行共享信道对应同一个混合自动重传请求确认(hybrid automatic repeat request-acknowledgment，HARQ-ACK)进程，或者HARQ进程号，或者同一组HARQ-ACK比特。即终端设备可针对多次重复传输的下行共享信道发送反馈信息，如肯定反馈(ACK)或否定反馈(NACK)。该重复传输分别所占的多个时频资源可以是在时域上互不重叠的。
为便于理解，本文所述的下行控制信道为调度重复传输的下行共享信道的控制信道。下行共享信道为重复传输的共享信道，该下行共享信道的重复传输次数m 1可以等于或大于1。
可以理解，下行共享信道可以传输多次，本文中将第一次传输下行共享信道简称为第 一次重复传输，相应的，第二次重复传输下行共享信道简称为第二次重复传输，每次重复传输下行共享信道简称为每次重复传输，重复传输下行共享信道的次数简称为重复传输的次数，等等。
请参阅图3，图3以时间单元为一个时隙(slot)为例，该时隙包括符号0至符号13，共14个符号。如图3所示，下行共享信道在slot内重复传输两次，每次传输占用四个符号，例如下行共享信道的第一次重复传输占用符号3至6；下行共享信道的第二次重复传输占用符号7至10。其中，符号的时间长度和子载波间隔相关。
一种情况，第一次重复传输与第二次重复传输可以对应不同的天线端口准共址(quasi co location,QCL)，例如，分别由TRP1和TRP2传输。其中，QCL关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征。例如，如果两个天线端口具有准共址关系，那么一个端口传送一个信号的信道大尺度特性可以从另一个端口传送一个信号的信道大尺度特性推断出来。
另一种情况，第一次重复传输和第二次重复传输可以对应同一个QCL，即由一个TRP重复传输两次该下行共享信道。
2、下行共享信道的相关处理、最小时间间隔、反馈时间间隔
终端设备需要执行DCI接收和译码、针对DMRS做信道估计、根据信道估计结果接收数据、生成数据接收结果、完成上行传输过程等一项或多项操作以上报反馈信息，因此，网络设备为终端设备配置的反馈时域资源的起始时域位置需要在最小时间间隔之后，最小时间间隔的设定就是考虑到上述操作设定的。本申请实施例中，最小时间间隔是下行共享信道传输结束时刻到反馈信息的反馈起始时刻之间的最小时间间隔。
以下行共享信道为物理下行共享信道(physical downlink sharechannel，PDSCH)为例，如图4所示，该PDSCH在时隙k内重复传输两次。从终端设备接收到PDSCH携带的DMRS的时刻到终端设备能够上报反馈信息的起始时刻之间，终端需要完成的PDSCH的相关处理包括：信道估计(channel estimation，CE)、根据信道估计的结果解调PDSCH(简称：解调(demodulation)、译码(decode))、根据解调的结果生成反馈信息以及进行上行控制信息的调制编码等(简称：上行链路处理(uplink processing,UL processing))。
其中，图4中，每个处理操作的操作结束后才能进行下一个处理操作，比如，针对第一次重复传输的处理过程，CE处理完毕，才能进行解调译码处理。并且每个处理操作对第一次重复传输的PDSCH处理结束后，才能对下一次重复传输的PDSCH进行处理。例如，CE对第一次重复传输的PDSCH进行信道估计后，才能对第二次重复传输的PDSCH进行信道估计。其中，为便于图示，图4中各处理操作的处理时长相同，同样的后续图示中也以各处理操作的处理时长相同为例，进行阐述，但这些附图并不用于限定本申请实施例中各处理操作的处理时长相同。
因此，如图4所示，网络设备需要确定最小时间间隔T，以确定反馈信息所占用的反馈时域资源，如以反馈时域资源为物理上行控制信道(physical uplink control channel，PUCCH)为例，时隙k+2中虚线框所示的PUCCH的起始时域位置需在该最小时间间隔之后，终端设备才能上报有效的反馈信息。
本申请实施例中，反馈时间间隔是基于网络设备指示的反馈时域资源而确定的实际反馈时间间隔。也就是说，该反馈时间间隔是下行共享信道的重复传输结束时刻到反馈信息的反馈起始时刻之间的实际时间间隔。
也就是说，确定最小时间间隔时所阐述的反馈起始时刻为终端设备完成重复传输的下行共享信道的相关处理后，能够上报反馈信息的起始时刻。确定反馈时间间隔所阐述的反馈起始时刻为基于网络设备指示的反馈时域资源而确定的实际反馈起始时刻。
3、重复传输模式下的相关参数
本申请实施例中，重复传输模式下的相关参数可包括：重复传输次数m 1、每次重复传输的起始时域位置和每次重复传输所占的时域资源包括的时间单元的数量。这些参数可通过但不限于，以下三种实施方式进行指示。
一种实施方式中，网络设备通过媒体接入控制控制元素(media access control-control element，MAC-CE)信令或高层信令通知终端设备重复传输次数m1。下行控制信息中的时域位置指示字段可用于指示第一次重复传输的起始时域位置(或称为起始符号位置)和第一次重复传输所占的时域资源包括的时间单元的数量(或称为长度、或符号数)。
例如，可通过预定义或信令配置如表1所示的时域位置指示，实际指示可以包括表1中的部分列。
表1 下行共享信道的时域位置指示
行索引 下行共享信道映射类型 K 0 S 0 L 0

11 Type B 0 12 2
12 Type A 0 1 13

16 Type B 0 8 4
第一列为下行控制信息中时域位置指示字段所指示的值，为行索引。
第二列为下行共享信道映射类型，包括映射类型A、B。映射类型A表示第一次重复传输的起始时域位置是下行控制信道所占的符号之后相邻的第一个符号，或者说，第一次重复传输的起始时域位置局限于一个slot内的前三个符号。如图5所示，下行控制信道所占的符号分别为符号0至2，第一次重复传输的起始时域位置是符号2相邻的符号3。映射类型B表示第一次重复传输的起始时域位置在一个slot内不做限定，可为下行控制信道所在时隙中的任一符号。如图6所示，下行控制信道所占的符号分别为符号0至2，第一次重复传输的起始时域位置是该时隙的符号2。其中，图6所示的两行符号是同一时隙的符号，以便于表示不同信道所占的符号可以重叠。
第三列K 0为第一次重复传输的下行共享信道在下行控制信道之后的时序偏移。比如，K 0等于0，表示第一次重复传输的起始时域位置在下行控制信道之后的时序偏移为0，即下行共享信道与下行控制信道位于同一个时隙。
第四列S 0为第一次重复传输在基于第三列确定的时隙中的起始时域位置。比如，S 0等于2，标示第一次重复传输的起始时域位置在时隙中的起始时域位置为符号2。
第五列L 0为第一次重复传输在基于第三列确定的时隙中所占的符号长度或符号数量。比如，L 0等于4，表示第一次重复传输占用4个符号。
该实施方式中，如图5所示的重复传输示意图，第一次重复传输的起始时域位置在下行控制信道所在的时域位置之后的第一个符号，即映射类型为A；下行共享信道与下行控制信道占用同一个时隙，即K 0等于0；下行共享信道在时隙中的起始时域位置为符号3，即S 0等于3；一次重复传输占用4个符号，即L 0等于4。也就是说，网络设备发送下行控制信息，该下行控制信息中时域位置指示字段的值为1时，终端设备可根据表1、表2确定出下行共享信道的映射类型、K 0、S 0、L 0的值；并且根据MAC-CE信令或高层信令配置的重复传输次数2，可确定，如图5所示，下行控制信道的重复传输的相关参数：重复传输次数m 1＝2、每次重复传输的起始时域位置分别是符号3、符号7和每次重复传输所占的时域资源包括的时间单元的数量为4个符号，此时协议会预先规定每次重复传输之间的没有时间间隔，而是连续排列的，同时，连续两次重复传输可以对应不同的QCL假设。
针对表1，在一种可能的设计中，以重复传输限定为位于一个slot内为例，假设MAC-CE信令或高层信令通知的重复传输次数m 1＝2，则表1中行索引为1可以表示在一个slot内执行重复传输，但对于行索引为2则无法在一个slot内执行重复传输，此时终端设备可以认为仅有一次重复传输。在另一种可能的设计中，不排除重复传输跨越slot边界的情况，比如，表1中行索引为2也可以执行两次重复传输，此时，第二次重复传输可能跨越slot边界，也可能仅承载于第二个slot内。
另一种实施方式中，重复传输的次数m 1与每一个候选时域位置指示所指示的行相关联，如表2所示，这样，基于下行控制信息中不同的时域位置指示的值不同，可基于表2获知相应的重复传输的次数m 1。
其中，表2与表1的不同之处在于，新增了一列重复传输的次数m 1。
在一种可能的设计中，该重复传输的次数可限定在一个slot内。比如，行索引为1时，表示在一个时隙内重复传输2次，重复传输的下行共享信道与下行控制信道占用同一个时隙，即K 0等于0；第一次重复传输的下行共享信道在时隙中的起始时域位置为符号3，即 S 0等于3；第一次重复传输占用4个符号，即L 0等于4。再比如，行索引为1时，表示在一个时隙内重复传输1次，重复传输的下行共享信道与下行控制信道占用同一个时隙，即即K 0等于0；第一次重复传输的下行共享信道在时隙中的起始时域位置为符号2，即S 0等于3；第一次重复传输占用10个符号，即L 0等于10。

14 Type A 0 2 4 3
15 Type B 0 4 7 1
16 Type B 0 8 4 1
又一种实施方式中，下行控制信息中的时域位置指示字段可用于指示一次完整重复传输过程所占时域资源的起始时域位置、时域资源包括的时间单元的数量、一次完整重复传输过程对应的重复传输次数。
其中，一次完整重复传输过程为时域上的m 1次重复传输。如图3、图5、图6所示，一次完整重复传输过程为下行共享信道在时域上的两次重复传输。
例如，可通过预定义或信令配置如表3所示的时域位置指示。

第二列为下行共享信道映射类型，包括映射类型A、B。该实施方式中，映射类型A表示一次完整重复传输过程的起始时域位置是下行控制信道所占的符号之后相邻的第一个符号。如图5所示，下行控制信道所占的符号分别为符号0至2，一次完整重复传输过程的起始时域位置是该时隙的符号3。映射类型B表示一次完整重复传输过程的起始时域位置在一个slot内不做限定，可为下行控制信道所在时隙中的任一符号。如图6所示，下行控制信道所占的符号分别为符号0至2，一次完整重复传输过程的起始时域位置是该时隙的符号2。其中，图6所示的两行符号是同一时隙的符号，为便于区分不同信道所占的符号数而示意为两行表示。
第三列K 1为一次完整重复传输过程在下行控制信道之后的时序偏移。比如，K 1等于0，表示一次完整重复传输过程的起始时域位置在下行控制信道之后的时序偏移为0，即下行共享信道与下行控制信道位于同一个时隙。
第四列S 1为一次完整重复传输过程在基于第三列确定的时隙中的起始时域位置。比如，S等于2，表示一次完整重复传输过程的起始时域位置在时隙中的起始时域位置为符号2。
第五列L 1为一次完整重复传输过程在基于第三列确定的时隙中所占的符号长度或符号数量。比如，L 1等于12，表示一次完整重复传输过程占用十二个符号。
第六列m 1为一次完整重复传输过程对应的重复传输次数。比如，m 1等于2，表示一次完整重复传输过程对应2次重复传输，连续两次重复传输对应相同的或者不同的QCL假设。
可选的，每次重复传输占用的时频资源在时域上不重叠。
该实施方式中，如图5所示的重复传输示意图，一次完整重复传输过程的起始时域位置在下行控制信道所在的时域位置之后的第一个符号，即映射类型为A；一次完整重复传输过程与下行控制信道占用同一个时隙，即K 1等于0；一次完整重复传输过程在时隙中的起始时域位置为符号3，即S等于3；一次完整重复传输过程占用8个符号，即L 1等于8；一次完整重复传输过程对应重复传输的次数为2次，即m 1等于2。也就是说，网络设备发送下行控制信息，该下行控制信息中时域位置指示字段的值为1时，终端设备可根据该下行控制信息确定出上述映射类型、K 1、S 1、L 1、m 1的值。即可获得重复传输模式的相关参数：重复传输次数m 1等于2、每次重复传输的起始时域位置分别是符号3、符号7和每次重复传输所占的时域资源包括的时间单元的数量为4个符号。
4、第一时域资源、第二时域资源、第三时域资源
本申请实施例中，第一时域资源为重复传输m 1次下行共享信道所占的总的时域资源。两次重复传输分别所占的时域资源之间的时间间隔可以为N个时间单元，该N可等于零或大于零。
在一种可能的设计中，第一时域资源还包括两次重复传输之间的时间间隔。也就是说，第一时域资源是指第一次重复传输的起始时域位置到最后一次重复传输的结束时域位置的时域资源。也就是说，第一时域资源中两次重复传输之间的时间间隔不用于承载传输块，而其他时域资源用于承载传输块。
比如，第k1次重复传输的结束时域位置到第k1+1次重复传输的起始时域位置之间的时域资源上不包括其他重复传输，且间隔m个符号，则m个符号为两次重复传输之间的时间间隔。可选的，若重复传输m 1次，则第一次重复传输的起始时域位置到最后一次重复传输的结束时域位置之间可以包括m 1-1个时间间隔，比如(m 1-1)ⅹm个符号。
例如，如图16所示，第一次重复传输与第二次重复传输之间的时间间隔为1个符号，第一时域资源包括：第一次重复传输所占的时域资源，即符号3至符号6；第二次重复传输所占的时域资源，即符号8至符号11；第一次重复传输与第二次重复传输之间的时间间隔，即符号7。因此，图16中，第一时域资源包括9个符号。
在另一种可能的设计中，第一时域资源为重复传输m 1次下行共享信道所占的总的时域资源。该设计不包括两次重复传输分别所占的时域资源之间的时间间隔。也就是说，第一时域资源均用于承载传输块。在一种可能的设计中，两次重复传输所占的时域资源之间的时间间隔可以是预先定义的，比如，当两次相邻的重复传输的QCL假设不相同时，存在该时间间隔，否则，不存在该时间间隔。或者两次重复传输所占的时域资源之间的时间间隔是网络设备通过信令配置的，或者是根据预设条件确定的。所述预设条件包括重复传输占用的时域资源中是否存在上行符号，或者，重复传输占用的时域资源中是否存在小区公共参考信号。
本申请实施例中，第二时域资源为DCI所在的时域资源，该DCI用于调度下行共享信道。可选的，该第二时域资源也可以为下行控制信道所占的时域资源，该下行控制信道承载的DCI用于调度下行共享信道。可选的，该第二时域资源也可以为DCI对应的搜索空间或者搜索空间集合所占的时域资源。搜索空间或者搜索空间集合用于指示待检测DCI在控制资源集合中所占的时频资源数量。每个待检测DCI均会对应特定的搜索空间或者搜索空间集合。控制资源集合用于指示终端设备在系统时频资源中的部分时频资源上检测DCI。例如，控制资源集合中包括待检测DCI所在的频域资源的数量和位置，以及在一个slot内的OFDM符号数量。例如，所述控制资源集合所占时域资源为一个时隙或子时隙中的1到3个符号。一个控制资源集合可以关联一个或多个搜索空间或搜索空间集合，一个控制资源集合所占的频域资源可以包括6N个RB，N大于或等于1。所述DCI所在的时隙或子时隙是根据搜索空间或搜索空间集合确定的。终端设备可以根据控制资源集合确定待检测该DCI的时频资源位置。
本申请实施例中，第三时域资源用于承载DCI，该DCI用于调度下行共享信道。也就是说，第二时域资源是检测到DCI实际所在的时域资源，第三时域资源是该DCI所在的控制资源集合包括的时域资源，是待检测DCI所在的时频资源池。终端设备需要基于第三时域资源确定检测该DCI的时频资源位置，从而检测到网络设备下发该DCI实际所在的时域资源。
5、时间单位
在一种实施方式中，最小时间间隔T、T1、各处理时延、时间间隔、时序偏移、反馈时间间隔或各预设值的单位可以为时间单元。
本申请实施例中，时间单元可以是一个或多个无线帧，一个或多个子帧，一个或多个 时隙，一个或多个微时隙(mini slot)，一个或多个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号、离散傅里叶变换扩频的正交频分复用(discrete fourier transform spread spectrum orthogonal frequency division multiplexing，DFT-S-OFDM)符号等，也可以是多个帧或子帧构成的时间窗口，例如系统信息(system information，SI)窗口。
例如，时间单元在时域内可包含整数个符号，如该时间单位可以是指子帧，也可以是指时隙(slot)，还可是指无线帧、微时隙(mini slot或sub slot)、多个聚合的时隙、多个聚合的子帧、符号等等，还可以是指传输时间间隔(Transmission Time Interval，TTI)。其中，一种时间单元在时域内可包含整数个另一种时间单位，或者，一种时间单位在时域内的时长等于整数个另一种时间单元在时域内的时长，例如，一个微时隙/子时隙/时隙/子帧/无线帧内包含整数个符号，一个时隙/子帧/无线帧内包含整数个微时隙，一个子帧/无线帧内包含整数个时隙，一个无线帧包含整数个子帧等，也可以存在其余包含举例，本申请不做限定。
在另一种实施方式中，最小时间间隔T、T1、各处理时延、时间间隔、反馈时间间隔或各预设值的单位也可以为绝对时间，绝对时间的单位为毫秒或者微秒。本申请中均以时间单元为例进行说明，时间单元可以根据不同的条件换算为绝对时间，例如，在子载波间隔为15kHz的情况下，一个时隙可以包括14个OFDM符号，对应1ms。
基于上述相关阐述，以下结合附图对本申请提供的反馈信息处理方法进行阐述。
请参阅图7，图7是本申请实施例提供的一种反馈信息处理方法的流程示意图。如图7所示，该反馈信息处理方法，包括但不限于以下步骤：
101、网络设备根据重复传输下行共享信道的次数m 1，确定最小时间间隔，m 1大于或等于2；
102、网络设备根据所述最小时间间隔，确定反馈时域资源，所述反馈时域资源用于反馈所述下行共享信道的反馈信息；
其中，最小时间间隔是所述下行共享信道的重复传输结束时刻到所述反馈信息的反馈起始时刻之间的最小时间间隔。具体的，该最小时间间隔的相关阐述可参见上文，此处不再详述。
在一种实施方式中，网络设备根据最小时间间隔，确定的反馈时域资源，可以为网络设备根据实际资源配置情况，向终端设备指示的反馈时域资源。相应的，终端设备可以从网络设备接收该最小时间间隔或与网络设备一样执行101的相关实施方式确定最小时间间隔；进而，终端设备可根据该最小时间间隔和反馈时间间隔，确定该下行共享信道的反馈信息。其中，终端设备可根据反馈时域资源确定反馈时间间隔。
其中，反馈时间间隔是下行共享信道的重复传输结束时刻到反馈信息的反馈起始时刻之间的实际时间间隔。例如，图4中，假设虚线框所示的PUCCH资源为网络设备为终端设备指示的反馈时域资源，则反馈时间间隔为重复传输结束时刻与该PUCCH资源的起始时刻之间的时间间隔。相应的，终端设备可在反馈时间间隔大于该最小时间间隔时，确定该下行共享信道的有效的反馈信息。
其中，PDSCH的结束时刻为PDSCH所占的最后一个符号，反馈的起始时刻为PUCCH 所占的slot的第一个符号，或者为PUCCH资源所占的第一符号。最小时间间隔是指，PDSCH的结束时刻之后的第一个符号到反馈的起始时刻之前的最后一个符号。
其中，该反馈时域资源上的PUCCH用于承载反馈信息。该实施方式中，为了使得终端设备可以上报有效反馈信息，网络设备可以根据最小时间间隔指示合理的反馈起始时刻，以使终端设备完成上述所有下行共享信道的处理流程。即在该反馈时域资源的起始时域位置之前，终端设备能够完成下行共享信道的相关处理，获得反馈信息。
以下从几个实施例阐述如何确定最小时间间隔，以下各实施例或实施方式可由网络设备执行，也可以由终端设备执行。以下内容以网络设备作为执行主体为例进行阐述。
实施例一
该实施例中，网络设备基于重复传输模式下的相关参数确定最小时间间隔。或者，网络设备根据重复传输模式的相关参数，确定最小时间间隔与T1之间的关系，该T1为重复传输次数为1时，即非重复传输模式下的最小时间间隔。
实施方式一最小时间间隔T与重复传输下行共享信道的次数相关。
在一种可能的设计中，重复传输下行共享信道的次数m 1越大，最小时间间隔T也越大。
如图8所示，图8是本申请实施例提供的重复传输的次数为1时下行共享信道处理的一示例图。图8与图4的不同之处在于，PDSCH的重复传输的次数不同。由于图4中，CE需处理完第一次重复传输的信道估计后再处理第二次重复传输的信道估计，即图8中PDSCH的处理开始时刻要早于图4中第二次重复传输的处理开始时刻，故图8中UL processing的处理结束时刻要早于图4中第二次重复传输的UL processing的处理结束时刻，因此，图4中的T要大于图8中的T。
在另一种可能的设计中，重复传输下行共享信道所占的总时域长度或所占时域资源包括的时间单元数量不变，重复传输下行共享信道的次数m 1越大，最小时间间隔T也越大。比如，上述示例中，重复传输的次数为1时的总时域长度为8个符号，重复传输的次数为2时的总时域长度也为8个符号，但重复传输的次数为2，该情况下，重复传输的次数为2的最小时间间隔大于重复传输的次数为1的最小时间间隔。
在又一种可能的设计中，重复传输下行共享信道的次数m 1，最小时间间隔T相对于重复传输的次数为1次时的最小时间间隔不增加m 1倍。比如，重复传输次数为1时，即非重复传输模式下的最小时间间隔为T1；重复传输次数为2时，该最小时间间隔T等于T1+X，则X大于零且小于T1。例如，图4的重复传输次数是图8的重复传输次数的两倍，但图4中的最小时间间隔小于图8中的最小时间间隔的两倍。
在又一种可能的设计中，当重复传输下行共享信道的次数m 1大于或者等于预设次数时，最小时间间隔T相对于重复传输次数为1时的最小时间间隔增加，当重复传输下行共享信道的次数m 1小于预设次数时，最小时间间隔T与重复传输次数为1时的最小时间间隔相同。
在又一种可能的设计中，重复传输下行共享信道的次数m 1大于2时，最小时间间隔T等于T1+Y，其中，Y大于或等于(m 1/2)*X，且小于(m 1-1)*T1。X为重复传输下行共享信道的次数m 1等于2时的最小时间间隔与重复传输下行共享信道的次数m 1等于1时的最小时间间隔T1之间的差值。
也就是说，重复传输次数大于2时，重复传输次数是2的倍数，增加的处理时延也可 能是重复传输的次数为2次时增加的处理时延的倍数，如Y等于(m 1/2)*X，或者大于翻倍后的值，如Y大于(m 1/2)*X。
如图9所示，图9与图4的不同之处在于，PDSCH的重复传输的次数不同。由于图9中，CE需处理完第一次重复传输的信道估计后再依次处理第二次、第三次、第四次的信道估计，故图9中第四次重复传输的处理开始时刻要远远晚于图4中第二次重复传输的处理开始时刻，故图9中第四次重复传输的UL processing的处理结束时刻要远远晚于图4中第二次重复传输的UL processing的处理结束时刻，故图9中的T大于图4中的T。假设图9中的T等于T1+Y，图4中的T等于T1+X，则由于图9的重复传输次数是图4的重复次数的2倍，故图9中T增加的处理时延是图4中的X的两倍或大于图4中的X的两倍的值，即Y大于或等于2X。
在又一种可能的设计中，重复传输包括的总时间单元数量相同的情况下，重复次数越多，相应的最小时间间隔越大。
实施方式二最小时间间隔与重复传输下行共享信道一次所占的时域资源包括的时间单元的数量有关。
在一种可能的设计中，网络设备根据重复传输的次数m 1，确定最小时间间隔T，包括：根据重复传输的次数m 1和重复传输下行共享信道一次所占的时域资源包括的时间单元数量，确定最小时间间隔T。其中，重复传输下行共享信道一次所占的时域资源包括的时间单元数量，如图3所示，为4个符号。
其中，在重复传输次数不变的情况下，重复传输下行共享信道一次所占的时域资源包括的时间单元的数量越小，最小时间间隔T越大。如图4所示，假设重复传输次数不变，但一次所占的时域资源变小，则两次重复传输的处理过程的开始时刻均需要后移，相应的，最小时间间隔T的反馈起始时刻也后移，故该情况下，最小时间间隔T相比之前是增大的。比如，同样是重复传输次数为2，当每次重复传输的长度变大时，最小时间间隔T的取值变小。
在另一种可能的设计中，当重复传输下行共享信道的次数m 1大于1时，重复传输一次所占的时域资源包括的时间单元的数量越大，最小时间间隔T越小。例如，重复传输的次数m 1等于1时，最小时间间隔为T1。重复传输的次数m 1等于2且重复传输一次所占的时域资源包括的时间单元的数量等于2个符号时，最小时间间隔T等于T1+X。重复传输的次数m 1等于2且重复传输一次所占的时域资源包括的时间单元的数量等于4个符号时，最小时间间隔T等于T1+Z。其中，Z小于X。
如图10所示，图10与图4相比不同之处在于，图10中重复传输PDSCH一次所占的时域资源包括的时间单元的数量要大于图4中重复传输PDSCH一次所占的时域资源包括的时间单元的数量。由于图10中重复传输PDSCH一次所占的时域资源包括的时间单元的数量相对较大，故相比于图4，CE能够提前处理第一次、第二次重复传输的信道估计。因此，图10中第二次重复传输PDSCH的处理开始时刻要远远早于图4中第二次重复传输的处理开始时刻，相应的，图10中UL processing的处理结束时刻要早于图4中第二次重复传输的UL processing的处理结束时刻，即图10中的最小时间间隔小于图4中的最小时间间隔。
在又一种可能的设计中，重复传输下行共享信道的次数m 1等于1时，最小时间间隔为T1。若重复传输下行共享信道的次数m 1大于1，且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量大于或等于第一预设值时，最小时间间隔等于T1；若重复传输下行共享信道的次数m 1大于1，且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量小于第一预设值时，最小时间间隔大于T1。
在又一种可能的设计中，重复传输下行共享信道的次数m 1等于1且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量为L时，最小时间间隔为T1。若重复传输下行共享信道的次数m 1大于1且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量L大于第二预设值时，最小时间间隔T等于T1；若重复传输下行共享信道的次数m 1大于1且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量L小于第二预设值时，最小时间间隔T大于T1。
在又一种可能的设计中，重复传输下行共享信道的次数m 1等于1且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量时，最小时间间隔为T1。若重复传输下行共享信道的次数m 1大于1且第一时域资源所包括的时间单元的数量大于等于第三预设值时，最小时间间隔等于T1；若重复传输下行共享信道的次数m 1大于1且第一时域资源小于第三预设值时，最小时间间隔大于T1。
也就是说，若重复传输下行共享信道一次所占的时域资源包括的时间单元的数量较大，则终端设备在下行共享信道的重复传输结束时刻之前，就已经能够并行处理重复传输的PDSCH，故与T1相比，最小时间间隔可不增加；若重复传输下行共享信道一次所占的时域资源包括的时间单元的数量较小，则在下行共享信道的重复传输结束时刻之后，终端设备还存在更多未处理完的PDSCH，故与T1相比，最小时间间隔增加。可选的，该情况下，第一预设值可以等于4个符号。
实施方式三最小时间间隔T与两次重复传输分别所占的时域资源之间的时间间隔有关。
在一种可能的设计中，根据重复传输下行共享信道的次数m 1，确定最小时间间隔T，包括：根据重复传输下行共享信道的次数m 1、重复传输所述下行共享信道一次所占的时域资源包括的时间单元的数量以及重复传输所述下行共享信道两次分别所占的时域资源之间的时间间隔，确定最小时间间隔T。
一种情况，该设计中，重复传输所述下行共享信道两次分别所占的时域资源之间的时间间隔越大，最小时间间隔越小。
如图11所示，图11与图4相比不同之处在于，图11中重复传输PDSCH两次分别所占的时域资源之间的时间间隔大于零。由于图11中第一次重复传输的PDSCH相对靠前，CE能够提前处理第一次、第二次重复传输的信道估计，故图11中第二次重复传输PDSCH的处理开始时刻要远远早于图4中第二次重复传输的处理开始时刻。相应的，图11中UL processing的处理结束时刻要早于图4中第二次重复传输的UL processing的处理结束时刻，即图10中的最小时间间隔小于图4中的最小时间间隔。
另一种情况，该设计中，重复传输下行共享信道的次数m 1等于1时，最小时间间隔为T1。若重复传输下行共享信道的次数m 1大于1，且重复传输PDSCH两次分别所占的时域资源之间的时间间隔大于或等于第四预设值时，最小时间间隔等于T1；若重复传输下行共 享信道的次数m 1大于1，且重复传输PDSCH两次分别所占的时域资源之间的时间间隔小于第四预设值时，最小时间间隔大于T1。
也就是说，若重复传输PDSCH两次分别所占的时域资源之间的时间间隔较大，则终端设备在下行共享信道的重复传输结束时刻之前，就已经能够并行处理重复传输的PDSCH，故与最小时间间隔T1相比，最小时间间隔不增加；若重复传输PDSCH两次分别所占的时域资源之间的时间间隔较小，则在下行共享信道的重复传输结束时刻之后，终端设备还存在更多未处理完的PDSCH，故最小时间间隔增加。可选的，该情况下，第五预设值可以为2个符号。
可见，上述各实施方式中，网络设备或终端设备可根据重复传输模式的相关参数，定义了最小时间间隔T；或者，网络设备或终端设备可根据重复传输模式的相关参数，确定最小时间间隔T与最小时间间隔T1之间的关系。
本申请实施例不限于上述各实施方式所述的最小时间间隔T与重复传输模式的相关参数之间的特征。比如，本申请实施例还包括以下实施方式：重复传输下行共享信道的次数m 1等于1时，最小时间间隔为T1。重复传输下行共享信道的次数m 1大于第六预设值时，最小时间间隔大于T1，且该最小时间间隔可根据重复传输下行共享信道一次所占的时域资源确定。或者，重复传输下行共享信道的次数m 1大于1且重复传输下行共享信道一次所占的时域资源包括的时间单元的数量小于第七预设值(比如4个符号)时，最小时间间隔T大于T1，且该最小时间间隔可根据重复传输下行共享信道一次所占的时域资源确定。
在又一种实施方式中，为了降低最小时间间隔确定的复杂度，且在某些情况下的PDSCH处理时延的要求相差不大，则可以预定义或高层信令配置：在重复传输次数m 1大于第七预设值且重复传输PDSCH一次所占的时域资源包括的时间单元的数量小于第八预设值的情况，最小时间间隔大于T1，但该最小时间间隔与T1的差值可基于终端处理复杂度的要求来确定。
可见，该实施例可根据重复传输模式下的相关参数，重新定义最小时间间隔或最小时间间隔与T1的关系。其中，T1是非重复传输模式下的最小时间间隔。
实施例二
该实施例中，最小时间间隔是由一个或多个处理时延相加获得的，该一个或多个处理时延包括第一处理时延d1.1和下行共享信道处理时延N1。
例如，当下行共享信道只传输一次，也即重复传输次数m 1等于1时，最小时间间隔T1可采用如下公式(1)获得：
T1＝N1+d1.1   (1)
该公式(1)表示在某个特定子载波间隔下，图7所示的非重复传输模式下，最小时间间隔T1是基于N1和d1.1确定的。其中，T1、N1、d1.1的单位为符号。若需获得该T1对应的绝对时间T 1′，则可基于如下公式(2)获得：
T 1′＝T1×(2048+144)·κ2 -μ·T c  (2)
其中，T c＝1/(Δf max·N f)表征了时间粒度，Δf max＝480·10 3Hz，N f＝4096。κ＝T s/T c＝64是一个恒定值，T s＝1/(Δf ref·N f,ref),Δf ref＝15·10 3Hz，N f,ref＝2048。其中，绝对时间T 1′的单位为毫秒或者微秒。
其中，N1与终端的下行共享信道处理能力有关；d1.1与终端的下行共享信道处理能力和下行共享信道所占的时域资源大小有关。比如，具有两种下行共享信道处理能力的终端设备，分别标记为Cap1能力和Cap2能力。由于具有Cap2能力的终端设备在执行上述各处理操作时所需的时间均比较短，因此，Cap2能力的终端设备相比于Cap1的终端设备，所需的最小时间间隔更小。例如，N1可通过表4、表5获得的。
表4 适用于下行共享信道处理能力1
Figure PCTCN2020119103-appb-000001
表5 适用于下行共享信道处理能力2
Figure PCTCN2020119103-appb-000002
其中，终端具有下行共享信道处理能力1时，基于表4确定N1。表4中，第一列为下行共享信道所在时间单元的子载波间隔μ。该N1还与下行共享信道是否具有附加DMRS有关，表4中第二列适用于下行共享信道没有附加解调参考信号(additional DMRS)以及下行共享信道映射类型A、B的情况，第三列适用于下行共享信道有附加DMRS以及下行共享信道映射类型A、B的情况。终端设备具有下行共享信道处理能力2时，基于表5确定N1。表5中，第一列为下行共享信道所在时间单元的子载波间隔μ。第二列适用于没有附加DMRS以及下行共享信道映射类型A、B的情况。
因此，一种实施方式中，可根据实施例一中各重复传输模式下的最小时间间隔与最小时间间隔T1之间的关系，预定义或高层信令配置重复传输模式下的N1。
也就是说，该实施方式中也可以采用表格的方式，预定义或高层信令配置一个或多个 重复传输模式下，N1的可选值。比如，基于上述实施例一所述的各实施方式，预定义或高层信令配置如表4、表5所示的表格，使得网络设备或终端设备可通过查表的方式确定重复传输模式下的N1。可选的，在重复传输模式下，每次重复传输的下行共享信道不具有附加DMRS，这样，表4中可去除第三列。
在非重复传输模式下，公式(1)中的d1.1与下行共享信道所占的时域资源的大小和终端具有的上述下行共享信道处理能力属于Cap 1能力还是Cap 2能力有关。
例如，对于Cap 1能力的终端设备，随着下行共享信道所占的时域资源的变小，最小时间间隔T1会依据条件变大。因此，当下行共享信道所占的时域资源为7个符号时，d1.1＝0；当下行共享信道所占的时域资源为4个符号时，d1.1＝3；当下行共享信道所占的时域资源为2个符号时，d1.1＝3+d，d是下行控制信道所占的时域资源与该下行共享信道所占的时域资源之间的重叠时域资源包括的时间单元的数量。
再例如，对于Cap 2能力的终端设备，随着下行共享信道所占的时域资源的变小，最小时间间隔T1依据条件可以保持不变。该条件为调度该下行共享信道的下行控制信道所占的时域资源与该下行共享信道所占的时域资源在时域上的位置关系有关。
比如，当下行共享信道所占的时域资源包括7个符号时，或者当下行共享信道所占的时域资源包括4或2个符号且下行共享信道所占的时域资源与调度该下行共享信道的下行控制信道所占的时域资源不重叠时，d1.1＝0。当下行共享信道所占的时域资源包括4个符号且下行共享信道所占的时域资源与调度该下行共享信道的下行控制信道所占的时域资源在时域上重叠时，d1.1等于重叠时域资源包括的符号数；当下行共享信道所占的时域资源包括2个符号且下行共享信道所占的时域资源与调度该下行共享信道的下行控制信道所占的时域资源具有相同的起始时域位置，且下行控制信道所占的时域资源包括3个符号时，d1.1＝3。
因此，另一种实施方式中，可以基于上述实施例一中各重复传输模式下最小时间间隔T与T1之间的关系，预定义或高层信令配置一个或多个重复传输模式下，d1.1的可选值。
例如，上述实施例一中的一设计方式，重复传输下行共享信道的次数m2大于等于m 1的两倍时，重复传输下行共享信道的次数m 1对应的最小时间间隔T1不大于重复传输下行共享信道的次数m2对应的最小时间间隔T2。再例如，非重复传输的下行共享信道的最小时间间隔为T1，那么：
重复传输下行共享信道的次数m 1等于2时，最小时间间隔中d1.1增加X，其中，X大于零且小于T1；
重复传输下行共享信道的次数m 1大于2时，最小时间间隔中d1.1增加Y，其中，Y大于或等于(m 1/2)*X，且小于(m1-1)*T1。
其中，N1的值还可以基于表4、表5和终端设备的下行共享信道处理能力确定。最小时间间隔中d1.1的值基于上述非重复传输模式的定义确定。
本申请实施例，还可以基于实施例一中的其他实施方式确定d1.1，此处不再详述。
综上所述，该实施例中，可通过协议预定义或高层信令配置：非重复传输模式下，最小时间间隔T1中包括的N1和d1.1(如上述对T1的阐述)；重复传输模式下，最小时间间隔T中N1的可选值，或者最小时间间隔T中N1相对于最小时间间隔T1中N1的增量， 或者最小时间间隔T中d1.1相对于最小时间间隔T1中d1.1的增量。
实施例三
该实施例与上述实施例二中确定第一处理时延d1.1的增量的方式不同，该实施例中重新定义第一处理时延d1.1，N1还可基于表4或表5获得，或者基于实施例一或二重新定义的表4或表5获得。
在一种实施方式中，第一处理时延d1.1是基于第一时域资源确定的。或者，第一处理时延d1.1与第一时域资源有关。或者，第一处理时延d1.1是基于第一时域资源包括的时间单元的数量确定的。或者，在所述第一时域资源包括的时间单元数量不同的情况下，所述第一处理时延d1.1的取值不同。
在一种实施方式中，所述第一时域资源包括K4个时间单元时，或者，第一时域资源中时间单元的数量大于K4时，所述第一处理时延d1.1等于零；或者，所述第一时域资源包括K3个时间单元时，或者第一时域资源中时间单元的数量大于K2且小于K4时，或者第一时域资源中时间单元的数量大于等于K3且小于K4时，所述第一处理时延d1.1等于预设值，所述预设值大于零。
在另一种实施方式中，网络设备根据所述第一时域资源包括的时间单元数量、所述第一时域资源与第三时域资源之间的时域位置关系，确定所述第一处理时延d1.1；其中，所述第三时域资源为下行控制信息DCI关联的控制资源集合所占的时域资源，所述DCI用于调度所述下行共享信道。
在一种可能的设计中，第一时域资源包括K2个时间单元，或者第一时域资源中时间单元的数量小于K2时，或者，第一时域资源包括的时间单元数量小于K3时：

可选的，在第一时域资源对应的符号数量为4，或者大于4且小于7，或者大于2且小于等于4时，d1.1＝d’，其中，d’为第三时域资源与该第一时域资源之间的重叠时域资源中承载下行数据的时间单元的数量，或d’为第二时域资源与该第一时域资源之间的重叠时域资源中承载下行数据的时间单元的数量。

实施例四
在上述实施例一至实施例三确定的最小时间间隔T的基础上，网络设备或终端设备还可基于第一时域资源中解调参考信号(demodulation reference signal，DMRS)所占的时域资源与第一信号所占的时域资源是否冲突确定所述最小时间间隔。也就是说，以下阐述当DMRS与第一信号冲突时如何定义最小时间间隔。
可选的，第一信号包括但不限于：小区专用参考信号(cell-specific RS，CRS)、控制资源集合(CORESET)、同步信号块(synchronisation signal block，SSB)、信道状态信息参考信号(channelstate information reference resource，CSI-RS)等。其中，CRS用于小区内的多个用户执行数据接收的信道估计的参考信号或者执行信道状态信息反馈的测量参考信号；CORESET为承载下行控制信息的时频资源，通常占用频域上多个RB，在时域上可以占用1-3个符号，CORESET会关联一个或者多个搜索空间，每个搜索空间用于配置终端设备检测DCI的检测行为或者检测进程或者检测周期等；CSI-RS为终端设备专用的用于测量信道的参考信号，通常会基于测量上报测量结果给基站。
本申请实施例中，每次重复传输中均包含用于解调该重复传输PDSCH的DMRS，DMRS会占用每次重复传输所占的时域资源中特定的一个或者多个符号。
一种示例为，每个DMRS均占用每次重复传输所占的时域资源中的第n个符号。如图13所示，第一次重复传输中的DMRS占用第一次重复传输所占的时域资源中的第1个符号，即符号3；第二次重复传输中的DMRS占用第二次重复传输所占的时域资源中的第1个符号，即符号7。
另一种示例为，每次重复传输中DMRS占用的符号为每次重复传输占用的时域资源中的前k个符号，k可以取1或者2。例如，针对图13，k取1。
也就是说，第一DMRS为第一时域资源中的DMRS，则该第一时域位置为每次重复传输下行共享信道所占的时域资源中的前k个符号或第n个符号；第一DMRS为除第一次重复传输外其他次重复传输的下行共享信道所占的时域资源中的DMRS，则该第一时域位置为所述其他次重复传输下行共享信道所占的时域资源中的前k个符号或第n个符号。
在一种可能的设计中，该第一DMRS占用的时域资源位置为预设的位置。在一种可能的设计中，该第一DMRS占用的时域资源位置与PDSCH的相对位置是预设的。
在一种可能的设计中，该最小时间间隔T包括第三处理时延，网络设备根据第一解调参考信号DMRS所占的时域位置确定该第三处理时延。
在另一种可能的设计中，网络设备根据第一解调参考信号DMRS所占的时域位置，调整上述各实施方式所确定的最小时间间隔T。
在又一种可能的设计中，所述网络设备根据第一信号所占的时域位置，确定所述第一DMRS所占的时域位置。在又一种可能的设计中，第一DMRS所占的时域位置为第一时域位置时，最小时间间隔为T1；第一DMRS所占的时域位置为第二时域位置时，最小时间间隔T等于T1+第三处理时延。
其中，第一DMRS为第一时域资源中的DMRS，则该第一时域位置为每次重复传输下行共享信道所占的时域资源中的前k个符号或第n个符号，或者，第一DMRS为除第一次重复传输外其他次重复传输的下行共享信道所占的时域资源中的DMRS，则该第一时域位置为所述其他次重复传输下行共享信道所占的时域资源中的前k个符号或第n个符号。
其中，第二时域位置包括第一信号所在的时域位置之后相邻的时域位置。第三处理时延为第一信号所占的时域资源中时间单元的数量。
也就是说，该实施方式中，当第一DMRS所占的时域资源与上述所述的第一信号所占的时域资源冲突时，第一DMRS的时域位置会进行调整以避免和其他信号发生冲突，从而影响数据解调性能。
例如，当第一DMRS所占的时域资源与上述所述的其他信号所占的时域资源冲突时，第一DMRS所占的时域资源的起始时域位置调整为CRS或者SSB占用的时域资源结束后的第一个符号。如图14中，两次重复传输分别占用符号2-5和符号6-9，第一DMRS为第二次重复传输的PDSCH所占的时域资源中的DMRS，该第一DMRS的第一时域位置为符号6，由于符号6上有CRS，故根据该符号6上的CRS，确定第一DMRS的时域位置为第二时域位置，即符号7。相应的，图14中，最小时间间隔T等于图14中上一行所示的重复传输对应的最小时间间隔T1加1。
也就是说，当第一DMRS的时域位置受到CRS或者SSB的影响而后移时，最小时间间隔T大于T1。其中，T1为第一DMRS未受到CRS或者SSB影响时定义的最小时间间隔或者为第一。比如，根据实施例三中第一时域资源与第一处理时延的关系，确定d1.1，再根据上述表4或表5确定N1，进而基于公式(1)获得T1。该实施方式中，网络设备可将所述最小时间间隔T1增加第三处理时延，从而确定最小时间间隔T。该第三处理时延是第一信号所占的时域资源包括的时间单元的数量。
如图14所示，重复传输下行共享信道2次中的两个DMRS中，第二次重复传输的DMRS所占的时域资源与CRS所占的时域资源冲突，则该DMRS后移一个符号。由于DMRS后移，引起第二次重复传输的处理过程中，CE的处理可能因为该DMRS后移而后移，故该情况下，最小时间间隔T增加，比如，增加一个符号。
在另一种可能的设计中，当第k次重复传输的DMRS所占的时域资源与第一信号所占的时域资源冲突时，将第k次重复传输以及第k次重复传输之后的所有重复传输均后移。
可选的，将第k次重复传输的起始时域位置调整到第一信号的结束符号位置的下一个符号。相应的，最小时间间隔是根据第一次重复传输的起始时域位置到调整后的最后一次重复传输的结束时域位置之间所包括的时间单元的数量确定的。也就是说，该实施方式中，第一时域资源为第一次重复传输的起始时域位置到调整后的最后一次重复传输的结束时域位置所包括的时间单元确定为第一时域资源。
在一种可能的设计中，该实施方式，可根据该第一时域资源，采用上述实施例三所述 的相关实施方式确定最小时间间隔。
在另一种可能的设计中，该实施方式中，最小时间间隔T等于T1+第三处理时延。该T1为第k次重复传输的DMRS所占的时域资源与第一信号所占的时域资源未冲突时，或第k次重复传输的DMRS未受到第一信号影响时的最小时间间隔。该第三处理时延是第k次重复传输的起始时域位置与该第k次重复传输的起始时域位置被调整到的位置之间的时间单元偏移量。
例如，图15所示，控制资源集合所占的时域资源分别是符号0、1、6、7，与第二次重复传输的DMRS所占的时域资源冲突，故将第二次重复传输的起始时域位置调整到该控制资源集合所占的结束时域位置的下一个符号，即符号8。调整后的第二次重复传输所占的时域资源为符号8至符号11。相应的，第一时域资源为符号2至符号11。可选的，可基于该第一时域资源确定最小时间间隔。可选的，可确定图15中第三处理时延等于2，从而可将未受控制资源集合影响时的最小时间间隔增加2，以获得调整后的最小时间间隔。
上述各实施例或各实施方式是基于每次重复传输均具有一个DMRS考虑的，如上述图13至图15所示，相应的，CE至少是从DMRS传输的结束时刻开始执行的。在又一种实施方式中，重复传输模式所具有的DMRS可以精简，相应的，上述所述的最小时间间隔也能够在上述各实施例或各实施方式的基础上适当的进行减小。由于整个重复传输过程的信道估计的处理数量减小，因此，该实施方式有利于降低下行共享信道的处理复杂度。
在又一种实施方式中，网络设备可根据终端设备能力，进一步调整或确定最小时间间隔。比如，网络设备接收终端设备上报的能力信息；网络设备根据该能力信息确定重复传输模式下的最小时间间隔。
其中，该能力信息可以为非重复传输模式下终端设备上报的载波数量。该载波数量表征了终端设备的并行处理能力。比如，该载波数量为4个载波，表示终端设备的并行处理能力为4。因此，若网络设备根据终端设备上报的载波数量，为终端设备配置的载波数量为该上报的载波数量的一半时，网络设备可假定终端设备可对同一载波内的多个下行共享信道进行并行处理。
如图12所示，图12与图4具有相同的重复传输模式的相关参数以及重复传输结束时刻，但图12中，终端设备可并行处理第一次重复传输的PDSCH和第二次重复传输的PDSCH。这样，图12中的最小时间间隔由第二次重复传输的处理过程确定，与非重复传输模式(重复传输次数m 1等于1)时如图8所示的处理过程相同，故该重复传输模式下，根据终端设备的能力信息可确定最小时间间隔为重复传输次数m 1等于1时的最小时间间隔T1。同理，该实施方式还可以基于终端设备的并行处理能力，对上述各实施方式或各实施例中阐述的最小时间间隔进行调整。
