Description

信号发送方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
目前，NR(New Radio，新无线)系统支持在一个服务小区(serving cell)中的一个BWP(Bandwidth Part，带宽部分)上最多包含一个半持续调度(SPS，Semi-persistent Scheduling)配置。并且，根据现有业务模型的需求，SPS的周期较长，最小周期为10ms。然而，随着新业务模型的引入，NR系统需要在一个服务小区的一个BWP上能够同时激活多个半持续调度配置。并且，SPS的最小传输周期也需要大幅度缩短。因此，当一个服务小区的一个BWP上的多个SPS配置同时激活时，它们对应的HARQ-ACK(Hybrid Automatic Repeat request-Acknowledgement，混合自动重传请求确认)信息有可能在同一时间单位内发送。然而，现有技术无法解决该问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，当至少两个SPS配置在同一个服务小区的相同BWP上同时激活时，它们所对应的HARQ-ACK信息有可能在同一个时间单位内发送。但是，现有机制无法处理该情况。如果没有相应的解决方案，会导致所述SPS配置所对应的周期、时域位置等受到限制；并且，由于多个激活SPS配置所对应的HARQ-ACK信息无法同时发送，可能会使得一部分SPS配置所对应的HARQ-ACK信息延迟发送，从而导致相应的HARQ-ACK反馈的时延增加，进而影响系统性能。
为了解决上述问题中的至少一个或者解决其他类似问题，本申请实施例提供了一种信号发送方法、装置和系统，使得当至少两个SPS配置在同一个小区同一个BWP上同时激活时，它们所对应的HARQ-ACK信息能够在同一个时间单位内反馈，这不仅使得网络侧可以更灵活地在同一个小区的同一个BWP中配置多个SPS(更灵活的 周期、起始位置等)，而且还能够降低SPS配置所对应的HARQ-ACK信息的时延。

根据本申请实施例的其它方面，提供了一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得计算机在网络设备中执行前述第二方面所述的方法。
本申请实施例的有益效果之一在于：根据本申请实施例的一个方面，确定各个SPS的PDSCH(物理下行共享信道)所对应的HARQ-ACK信息的比特(bit)的位置，由此，网络设备能够根据HARQ-ACK信息中比特(bit)的先后顺序确定该HARQ-ACK信息的含义，也即网络设备能够通过HARQ-ACK信息中ACK/NACK比特的位置确定终端设备是否成功接收相应SPS PDSCH。根据本申请实施例的另一个方面，选择用于承载该HARQ-ACK信息的上行信号(上行资源)，由此，该HARQ-ACK信息能够使用时频大小合适的上行信号(上行资源)进行传输，保证了传输的可靠性，从而提升系统的性能。

在本申请实施例中，术语“通信网络”或“无线通信网络”可以指符合如下任意通信标准的网络，例如长期演进(LTE，Long Term Evolution)、增强的长期演进(LTE-A，LTE-Advanced)、宽带码分多址接入(WCDMA，Wideband Code Division Multiple Access)、高速报文接入(HSPA，High-Speed Packet Access)等等。
并且，通信系统中设备之间的通信可以根据任意阶段的通信协议进行，例如可以包括但不限于如下通信协议：1G(generation)、2G、2.5G、2.75G、3G、4G、4.5G以及未来的5G、新无线(NR，New Radio)等等，和/或其他目前已知或未来将被开发的通信协议。
在本申请实施例中，术语“网络设备”例如是指通信系统中将终端设备接入通信网络并为该终端设备提供服务的设备。网络设备可以包括但不限于如下设备：基站(BS，Base Station)、接入点(AP、Access Point)、发送接收点(TRP，Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC，Radio Network Controller)、基站控制器(BSC，Base Station Controller)等等。
其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本申请实施例中，术语“用户设备”(UE，User Equipment)例如是指通过网络设备接入通信网络并接收网络服务的设备，也可以称为“终端设备”(TE，Terminal  Equipment)。终端设备可以是固定的或移动的，并且也可以称为移动台(MS，Mobile Station)、终端、用户、用户台(SS，Subscriber Station)、接入终端(AT，Access Terminal)、站，等等。
其中，终端设备可以包括但不限于如下设备：蜂窝电话(Cellular Phone)、个人数字助理(PDA，Personal Digital Assistant)、无线调制解调器、无线通信设备、手持设备、机器型通信设备、膝上型计算机、无绳电话、智能手机、智能手表、数字相机，等等。
再例如，在物联网(IoT，Internet of Things)等场景下，终端设备还可以是进行监控或测量的机器或装置，例如可以包括但不限于：机器类通信(MTC，Machine Type Communication)终端、车载通信终端、设备到设备(D2D，Device to Device)终端、机器到机器(M2M，Machine to Machine)终端，等等。
目前，在NR系统中，物理层下行数据传输引入了数据信号接收反馈机制。具体的说，UE会根据基站的指示(PDCCH，物理下行控制信道)在指定的时频位置接收PDSCH，与此同时，UE需要对该PDSCH的接收做出相应的HARQ反馈。当UE在所述时频位置成功地解码所述PDSCH时，UE需要向基站反馈ACK；当UE未能在所述时频位置解码所述PDSCH时，UE需要向基站反馈NACK。通过接收UE的HARQ反馈，基站可以判断哪些下行数据需要相应的重传，同时也可以根据HARQ反馈中ACK和NACK的比例判断下行信道的质量，从而相应地调整下行传输的调制编码方式。
另外，在NR系统中，对于下行数据的调度主要分为两种方式：动态调度(dynamic scheduling)和半持续调度(Semi-persistent Scheduling，SPS)。对于动态调度而言，一个PDCCH调度一个对应的PDSCH。而半持续调度是指，一个PDCCH可以激活一系列的PDSCH传输，其中一系列PDSCH以P为周期重复传输。当UE接收到半持续调度的激活信令时，UE根据PDCCH中的指示以及预先配置的指示，得到第一个PDSCH的时频位置，此后UE根据之前存储的PDCCH指示以及相关的配置信息继续在时域上周期性地接收或监听PDSCH。当UE接收到半持续调度的去激活信令时，UE停止接收或监听相应的PDSCH。
无论是动态调度还是半持续调度，对应每个PDSCH，UE一般都会反馈ACK或NACK信息，也即进行HARQ反馈。
对于动态调度而言，指示相应PDSCH的下行控制信息(DCI)中包含PDSCH-to-HARQ_feedback timing indicator域，该域用于指示PDSCH和承载相应的HARQ-ACK信息比特(简称为HARQ bit)的PUCCH资源之间的偏移量k，如图1所示。即当PDSCH处于slot n时，它相应的ACK或NACK反馈在slot n+k发送。另外，所述DCI中也包含PUCCH resource indicator域，用于指示承载相应HARQ-ACK信息比特的PUCCH资源。
对于半持续调度而言，用于激活SPS的DCI中包含PDSCH-to-HARQ_feedback timing indicator域，该域用于指示每个PDSCH和承载相应的HARQ-ACK信息比特的PUCCH资源之间的偏移量k，如图2所示。另外，除了激活DCI直接指示的PDSCH之外，如果在相应的时隙仅有(没有对应PDCCH的)PDSCH所对应的HARQ反馈，则UE根据SPS配置中的IE n1PUCCH-AN确定用于承载相应HARQ-ACK信息比特的PUCCH资源。
当大于一个PDSCH的ACK/NACK反馈(也即HARQ-ACK信息)被指示在同一个时隙发送时，为了避免功率损失，半持续调度所对应的ACK/NACK信息比特与动态调度所对应的ACK/NACK信息比特需要复用在同一个上行资源中。如图3所示，当动态调度与半静态调度的ACK/NACK反馈被指示在同一个时隙发送时，它们相应的ACK/NACK反馈内容将会放在一起，并且在动态调度(DCI#2)所指示的上行资源上进行反馈。
另外，当不同PDSCH所对应的HARQ-ACK信息在同一个时隙发送时，UE会根据预定义的规则确定相应HARQ-ACK信息比特的先后顺序，从而生成相应的HARQ-ACK codebook。当该codebook生成之后，UE将会发送一个用于承载该codebook的上行信号(PUCCH/PUSCH)。
在本申请实施例的说明中，HARQ-ACK信息也即HARQ反馈信息，既可能包含ACK信息比特，也可能包含NACK信息比特。
在图1-图3以及对应的说明中，以时隙作为时间单位，但本申请不限于此，本申请涉及的时间单位也可以是符号(symbol)或者子时隙(sub-slot)或者帧(frame)或者子帧(sub-frame)等。
以下通过示例对本申请实施例的场景进行说明，但本申请实施例不限于此。
图4是本申请实施例的应用场景的示意图，如图4所示，在本申请实施例中，为 了方便说明，定义了第一集合的概念，该第一集合至少包括{SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M}，其中，一个元素表示一个SPS PDSCH接收，记为SPS PDSCH#m，m＝1，2，3，…，M，(M>＝2)。并且，在本申请实施例中，SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M对应于相同的BWP或CC或服务小区(serving cell)或相同服务小区的相同BWP。
在本申请实施例中，一种实施方式为，终端设备被配置在时隙n-K m接收SPS PDSCH#m，且SPS PDSCH#m是被激活的，也即，SPS PDSCH#m所对应的SPS配置在时隙n-K m处于激活状态。其中，n是指SPS PDSCH#m所对应的发送反馈信息的时隙；K m是指SPS PDSCH#m的PDSCH与对应的HARQ反馈之间的时域偏移量(PDSCH-to-HARQ-ACK-feedback timing value)，也即，SPS PDSCH#m接收所在的时隙与相应HARQ-ACK信息所在的时隙之间的时隙间隔。需要注意的是，该第一集合中的所有SPS PDSCH接收所对应的HARQ-ACK信息的发送时间在相同的时隙(也即时隙n)。
在本申请实施例中，另一种实施方式为，终端设备被配置在时隙n m接收SPS PDSCH#m，且SPS PDSCH#m是被激活的，也即，SPS PDSCH#m所对应的SPS配置在时隙n m处于激活状态。这里，SPS PDSCH#m所对应的(上行)子时隙为n’–K’ m，也即SPS PDSCH#m所对应的PDSCH结束符号在子时隙n’–K’ m。其中，n’是指SPS PDSCH#m所对应的发送反馈信息的子时隙，也即，该反馈信息所对应的上行信号的起始符号在子时隙n’；K’ m是指SPS PDSCH#m所对应的PDSCH的结束符号所对应的子时隙与SPS PDSCH#m对应的HARQ反馈的结束符号所对应的子时隙之间的子时隙间隔(PDSCH-to-HARQ-ACK-feedback timing value)。需要注意的是，该第一集合中的所有SPS PDSCH接收所对应的HARQ-ACK信息的发送时间在相同的子时隙(也即子时隙n’)。
以上说明仅以时隙、子时隙为例，上述描述中的时间单位也可以是子帧或者符号或者帧。
下面结合附图对本申请的各种实施方式进行说明。这些实施方式只是示例性的，不是对本申请的限制。
第一方面的实施例
本申请第一方面的实施例提供了一种信号发送方法，该方法应用于终端设备。图 5是本申请第一方面的实施例的信号发送方法的示意图，请参照图5，该方法包括：
操作501：终端设备至少根据第一集合生成第一反馈信号，所述第一集合至少包括两个SPS PDSCH接收，并且所述第一集合的SPS PDSCH接收对应相同的带宽部分(BWP)或载波单元(Component Carrier)或服务小区(serving cell)或相同服务小区的相同BWP；
操作502：所述终端设备发送所述第一反馈信号。
根据本申请实施例，在同一个BWP或CC或serving cell或相同serving cell的相同BWP上(也即一个服务小区的同一个BWP)，至少两个SPS PDSCH接收所对应的HARQ ACK信息能够在同一个时间单位内反馈，由此，网络设备可以更灵活地在同一个BWP或CC或serving cell或相同serving cell的相同BWP中配置多个SPS，而且还能够降低SPS反馈信息的时延。
在本申请实施例中，SPS PDSCH接收是指，终端设备根据SPS激活DCI以及相应的SPS配置信息监听或接收相应的PDSCH。当终端设备在相应时频位置成功解码该SPS PDSCH，则反馈ACK，如果在相应时频位置没有成功解码该SPS PDSCH，则反馈NACK。这里，SPS激活DCI(即用于激活SPS的DCI)是指，关于相应的SPS配置，时域上最近的SPS激活DCI，也即该SPS激活DCI与其相应的SPS PDSCH之间没有其它的(属于同一个SPS配置的)SPS激活DCI。另外，该SPS激活DCI例如可以是由CS-RNTI加扰的DCI format。其中，例如，SPS激活DCI中用于使能传输块的新数据指示符域(new data indicator field)为“0”，即“a new data indicator field for the enabled transport block is set to‘0’”。
以图2为例，SPS激活DCI为最左侧的DCI，SPS PDSCH接收是指UE在slot n监听/接收相应的PDSCH或在slot n+P接收/监听相应的PDSCH，或后续地以P为周期的slot监听/接收相应的PDSCH(例如，slot n+2P)。以图3为例，SPS激活DCI为DCI#1，SPS PDSCH接收是指UE在slot n监听/接收相应的PDSCH或在slot n+P接收/监听相应的PDSCH，或后续地以P为周期的slot监听/接收相应的PDSCH(例如，slot n+2P)。在图3的示例中，DCI#2为动态DCI而不是前述的SPS激活DCI，DCI#2调度的PDSCH并非前述的SPS PDSCH接收所对应的PDSCH。
在本申请实施例的至少一个实施例中，第一集合中的SPS PDSCH接收对应相同的HARQ-ACK码本(codebook)，由此，能够更好地利用系统资源，同时也能保证 传输可靠性。例如，SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M的HARQ-ACK反馈对应相同的HARQ-ACK codebook，该HARQ-ACK codebook可以是基于时隙的(slot-based)也可以是基于子时隙的(sub-slot based)，本申请不限于此。
在一个实施例中，上述第一集合中的SPS PDSCH接收(SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M)所对应的SPS配置的HARQ-ACK codebook标识(identifier)相同。
例如，在所述第一集合中，所有SPS PDSCH接收所对应的与半持续调度相关的RRC IE中包含‘codebook＝slot-based’，也即，所有的PDSCH的HARQ反馈属于slot-based HARQ-ACK codebook。这里，slot-based是指，HARQ-ACK信息所对应的上行资源的时域位置是由以slot为单位的时域指示确定的。
再例如，在所述第一集合中，所有SPS PDSCH接收所对应的与半持续调度相关的RRC IE中包含‘codebook＝sub-slot based’，也即，所有的PDSCH的HARQ反馈属于sub-slot based HARQ-ACK codebook。这里，sub-slot based是指，HARQ-ACK信息所对应的上行资源的时域位置是由以sub-slot为单位的时域指示确定的。
再例如，在所述第一集合中，所有SPS PDSCH接收所对应的与半持续调度相关的RRC IE中包含‘codebook＝1’，也即，所有的PDSCH的HARQ-ACK信息对应于第一HARQ-ACK codebook。
再例如，在所述第一集合中，所有SPS PDSCH接收所对应的与半持续调度相关的RRC IE中包含‘codebook＝2’，也即，所有的PDSCH的HARQ-ACK信息对应于第二HARQ-ACK codebook。
以上只是举例说明，本申请不限于此，根据上述例子还可以推导出其他类似的例子，此处省略说明。
在另一个实施例中，上述第一集合中的SPS PDSCH接收(SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M)所对应的SPS激活DCI中的HARQ-ACK codebook标识(identifier)相同。这里与SPS PDSCH接收相对应的SPS激活DCI是指，该SPS PDSCH接收以及该SPS激活DCI对应于相同的SPS配置。
例如，SPS激活DCI中包含一个域，该域的大小为1比特，其中码点(codepoint)为‘0’时，代表slot-based HARQ-ACK codebook，而codepoint为‘1’时，代表sub-slotbased HARQ-ACK codebook。这里，SPS PDSCH#1，SPS PDSCH#2，…，SPS  PDSCH#M所对应的SPS激活DCI中这个域的值是相同的(‘0’/‘1’)。
再例如，SPS激活DCI中包含一个域，该域的大小为2比特，其中，codepoint为‘00’时，代表HARQ-ACK codebook 1，而codepoint为‘01’时，代表HARQ-ACK codebook 2，而codepoint为‘10’时，代表HARQ-ACK codebook 3，而codepoint为‘11’时，代表HARQ-ACK codebook 4。这里，SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M所对应的SPS激活DCI中的这个域的值是相同的。
在本申请实施例的至少一个实施例中，上述第一反馈信号包括上述第一集合中的SPS PDSCH接收所对应的反馈信息，并且，该第一集合中的SPS PDSCH接收所对应的反馈信息在该第一反馈信号中的顺序与以下至少一种方式相关(或者由以下至少一种方式确定)：
第一集合中的SPS PDSCH接收所对应的PDSCH的起始时域位置或结束时域位置的先后；
第一集合中的SPS PDSCH接收所对应的SPS配置ID的升序或降序；以及
第一集合中的SPS PDSCH接收所对应的SPS激活DCI的起始时域位置或结束时域位置的先后。
由此，终端设备和网络设备能够根据HARQ-ACK信息的比特(bit)的先后顺序确定该HARQ-ACK信息的含义。也即，能够确定所述第一集合中对应的SPS PDSCH接收是否成功。
此外，当上述顺序与第一集合中的SPS PDSCH接收所对应的PDSCH的起始时域位置或结束时域位置的先后相关时，不仅能够使得PDSCH的起始/结束位置可以用于区分对应HARQ-ACK信息比特(bit)的顺序，也可以使得PDSCH时域位置较前的SPS PDSCH接收能够得到优先处理从而更早地生成HARQ-ACK信息比特，符合硬件的处理时序，加速处理过程，从而节省系统资源的开销。
此外，当上述顺序与第一集合中的SPS PDSCH接收所对应的SPS配置ID的升序或降序相关时，不仅能够使得PDSCH对应的SPS配置ID能够区分对应HARQ-ACK信息比特的顺序，也可以使得不同SPS配置ID所对应的PDSCH有不同的优先等级，也即当UE无法传送所有第一集合SPS PDSCH接收所对应的HARQ-ACK bit时，可以根据该先后顺序去除一部分比特，从而使得反馈信息的比特数与相应的传输资源匹配。
此外，当上述顺序与第一集合中的SPS PDSCH接收所对应的SPS激活DCI的起始时域位置或结束时域位置的先后相关时，不仅能够使得PDSCH对应的SPS激活DCI能够区分对应HARQ-ACK信息比特的顺序，也可以使得不同SPS激活DCI所对应的PDSCH有不同的优先等级，也即当UE无法传送所有第一集合SPS PDSCH接收所对应的HARQ-ACK信息比特时，可以根据该先后顺序去除一部分比特，从而使得反馈信息的比特数与相应的传输资源匹配。
与前述时间单位类似，上述时域位置可以是帧(frame)、子帧(subframe)、时隙(slot)、子时隙(sub-slot)、符号(symbol)中的其中一个，本申请不限于此。
例如，假设SPS PDSCH#1，SPS PDSCH#2，…，SPS PDSCH#M所对应的反馈信息比特分别为O 1,O 2,…,O M。在所述第一反馈信号中，假设反馈信息比特的顺序为{O 1,O 2,…,O M}(从O 1至O M)，则该顺序由以下方法之一确定：
方法1，PDSCH信号的起始或结束位置，即上述顺序由SPS PDSCH#m所对应PDSCH信号的起始/结束位置来决定，例如，SPS PDSCH#m所对应PDSCH信号的起始符号为StartPDSCH#m，则：
按照对应PDSCH信号的起始位置的时域升序排列是指：StartPDSCH#1>＝StartPDSCH#2>＝…>＝StartPDSCH#M；
按照对应PDSCH信号的起始位置的时域降序排列是指：StartPDSCH#1<＝StartPDSCH#2<＝…<＝StartPDSCH#M。
方法2，SPS配置ID，即，上述顺序由SPS PDSCH#m所对应SPS configuration ID(SPS config#m)的大小来决定，例如，
按照对应SPS configuration ID的升序：SPS config#1>＝SPS config#2>＝…>＝SPS config#M；
按照对应SPS configuration ID的降序：SPS config#1<＝SPS config#2<＝…<＝SPS config#M。
方法3，SPS激活DCI的起始或结束位置，即上述顺序由SPS PDSCH#m所对应的SPS激活DCI的起始/结束位置来决定，例如，SPS PDSCH#m所对应的SPS激活DCI的起始符号为StartPDCCH#m，则：
按照对应PUCCH信号的起始位置的时域升序排列是指：StartPDCCH#1>＝StartPDCCH#2>＝…>＝StartPDCCH#M；
按照对应PUCCH信号的起始位置的时域降序排列是指：StartPDCCH#1<＝StartPDCCH#2<＝…<＝StartPDCCH#M。
这里，SPS PDSCH#m所对应的SPS激活DCI是指，与SPS PDSCH#m时域距离最近且对应相同SPS配置的SPS激活DCI。
上述三种方法可以分别使用，也可以组合使用，例如，先比较PDSCH的起始位置，如果相同，则进一步比较SPS配置ID的大小，反之亦然；再例如，先比较SPS配置ID的大小，再比较SPS激活DCI的位置等，反之亦然。
在本申请实施例的上述操作501中，在至少一个实施例中，终端设备可以根据第一集合以及最大HARQ-ACK信息比特数，生成上述第一反馈信号。这里，最大HARQ-ACK信息比特数是指：一个上行信号中(例如，PUCCH)与SPS相关的最大HARQ-ACK信息比特数。
在一个实施例中，该最大HARQ-ACK信息比特数可以是RRC(无线资源控制)信令指示的，也即由网络设备通过RRC信令配置的。
例如，网络设备向终端设备发送RRC信令，其指示终端设备在一个上行资源中最多允许在一个上行资源/信号中发送N max个与SPS相关的HARQ反馈比特，则，N max为上述最大HARQ-ACK信息比特数，并且，
当所述第一集合中所有SPS PDSCH接收所对应的HARQ-ACK比特总数小于等于N max时，所述第一反馈信号中包含所有第一集合中SPS PDSCH接收所对应的SPS HARQ反馈比特；
当所述第一集合中所有SPS PDSCH接收所对应的HARQ-ACK比特总数大于N max时，所述第一反馈信号包含最多N max个与第一集合中SPS PDSCH接收相对应的HARQ-ACK比特。此时，第一集合只有一部分SPS PDSCH接收所对应的HARQ-ACK信息包含在所述第一反馈信号中。
在本申请实施例中，终端设备可以根据第一集合中的SPS PDSCH接收所对应的PDSCH起始/结束时域位置的先后，确定上述一部分SPS PDSCH接收。例如，所述第一反馈信号只包括对应的PDSCH起始位置最前的SPS PDSCH接收的反馈信息(HARQ-ACK比特)，以使得发送比特数小于或等于上述N max。
在本申请实施例中，终端设备也可以根据第一集合中的SPS PDSCH接收所对应的SPS配置ID的升序/降序，确定上述一部分SPS PDSCH接收。例如，所述第一反 馈信号只包括对应的SPS configuration ID较小的PDSCH接收的反馈信息(HARQ-ACK比特)，以使得发送比特数小于或等于上述N max。
在本申请实施例中，终端设备还可以根据第一集合中的SPS PDSCH接收所对应的SPS激活DCI的起始/结束时域位置的先后，确定上述一部分SPS PDSCH接收。例如，所述第一反馈信号只包括对应的SPS激活DCI较早的PDSCH接收的反馈信息(HARQ-ACK比特)，以使得发送比特数小于或等于上述N max。
以上三种方式可以分别使用，也可以组合使用，例如，先比较PDSCH的起始位置，如果相同，则进一步比较SPS配置ID的大小，反之亦然；再例如，先比较SPS配置ID的大小，再比较SPS激活DCI的位置等，反之亦然。本申请不限于此。
在另一个实施例中，上述最大HARQ-ACK信息比特数也可以与该第一反馈信号的容量(capacity)相关。也即，最多允许发送N max个与SPS相关的HARQ反馈比特不是由RRC信令指示而是与该第一反馈信号的容量相关，例如，相等。该容量与上述第一反馈信号的时频域资源、调制方式(MCS)和/或码率相关，本申请对此不再赘述。由此，可以避免额外的指示信令指示最大HARQ-ACK信息比特数，从而减少系统的资源开销。
在本申请实施例的上述操作501中，在至少一个实施例中，终端设备可以根据第一集合以及最大的与HARQ-ACK信息相关的ACK的个数，生成上述第一反馈信号。这里，HARQ-ACK信息是指与SPS相关的HARQ-ACK信息。
在一个实施例中，最大的与HARQ-ACK信息相关的ACK的个数是指，一个上行信号中(例如，PUCCH)最大的与HARQ-ACK信息相关的ACK的个数，它可以是由RRC信令指示的，也即由网络设备通过RRC信令配置的。
例如，网络设备向终端设备发送RRC信令，其指示终端设备在一个上行资源中最多允许发送P个与SPS相关的‘ACK’，也即指示终端设备最多有P个有效的SPS PDSCH接收所对应的HARQ信息可以为ACK，所述第一集合中其它的SPS PDSCH接收所对应的HARQ信息为NACK。因此，反馈信息中可能包括的ACK的个数为0,1,2,…,P，假设所述第一反馈信号中所对应的与SPS相关的HARQ反馈比特个数为N，则反馈可能发生的状态分别为
Figure PCTCN2019100868-appb-000001
Figure PCTCN2019100868-appb-000002
所以，终端设备不必在所述第一反馈信号中生成N比特HARQ-ACK信息，而是生成一 定的比特数对应上述所有可能性出现的状态，即在所述第一反馈信号中生成的比特数为：
Figure PCTCN2019100868-appb-000003
这样，RRC信令可以灵活配置ACK的个数，从而能使更多SPS PDSCH在相同时间单位内反馈HARQ-ACK信息。另外，限制ACK的个数可以极大地缩减可能的反馈信息的组合，从而节省HARQ反馈所需要的信息比特开销。
在另一个实施例中，上述最大的与HARQ-ACK信息相关的ACK的个数是预定义的。也即，最多允许发送P个与SPS相关的ACK不是由RRC指示的而是预定义的，例如为2。这样可以避免额外的指示信令(用以指示ACK的个数)，节省信令开销。
根据本申请实施例的以上方法，在HARQ-ACK信息中，可以确定各个SPS PDSCH所对应的HARQ-ACK信息比特的位置，由此，网络设备和终端设备能够根据HARQ-ACK信息比特的先后顺序确定反馈信息的含义。
在本申请实施例中，在至少一个实施例中，上述第一反馈信号仅包括不对应PDCCH的PDSCH接收(PDSCH without corresponding PDCCH)所对应的HARQ-ACK信息，而不包括对应PDCCH的PDSCH接收(PDSCH with corresponding PDCCH)所对应的HARQ-ACK信息。这里，PDSCH without corresponding PDCCH是指没有PDCCH直接调度该PDSCH，例如SPS中除了SPS激活DCI指示的初始(initial)PDSCH以外的PDSCH。这里，初始PDSCH是指SPS激活DCI之后的第一个对应的PDSCH。由此，由于没有直接对应的PDCCH，第一反馈信号的资源指示无法直接由PDCCH提供，则该资源可以是上述第一集合中的一个SPS PDSCH接收所对应的上行资源，或者，也可以是第二集合中的上行资源，该第二集合中的上行资源可以与前述第一集合中的SPS PDSCH接收所对应的HARQ-ACK信息的大小相关，具体方式将在下面进行说明。
在本申请实施例中，在操作502的至少一个实施例中，终端设备可以使用第一上行资源发送上述第一反馈信号，该第一上行资源可以是上述第一集合中的一个SPS PDSCH接收所对应的配置的上行资源。
例如，该第一上行资源所对应的SPS PDSCH接收可以是上述第一集合中的SPS PDSCH接收对应的SPS配置ID最大或最小的一个SPS PDSCH接收。假设所述第一集合中SPS PDSCH#m所对应的配置的用于HARQ-ACK反馈的PUCCH资源为 PUCCH m，并且，SPS PDSCH#m所对应的SPS configuration ID为SPS m，则终端设备可以根据PUCCH i发送所述第一反馈信号，其中

或者

再例如，该第一上行资源所对应的SPS PDSCH接收可以是上述第一集合中的SPS PDSCH接收对应的PDSCH起始时域位置或结束时域位置最早或最晚的一个SPS PDSCH接收。假设第一集合中SPS PDSCH#m所对应的配置的用于HARQ-ACK反馈的PUCCH资源为PUCCH m。另外，SPS PDSCH#m所对应的PDSCH起始时域位置(符号/时隙/子时隙)为

或者

再例如，该第一上行资源所对应的SPS PDSCH接收可以是上述第一集合中的SPS PDSCH接收对应的配置的HARQ PUCCH资源起始时域位置或结束时域位置最早或最晚的一个SPS PDSCH接收。假设第一集合中SPS PDSCH#m所对应的配置的用于HARQ-ACK反馈的PUCCH资源为PUCCH m(例如，是相应SPS配置SPS-config中关于HARQ PUCCH资源的指示IE：n1PUCCH-AN所指示的PUCCH资源)。另外，PUCCH m的起始时域位置(符号/时隙/子时隙)为

或者
Figure PCTCN2019100868-appb-000011
再例如，该第一上行资源所对应的SPS PDSCH接收可以是上述第一集合中的SPS PDSCH接收对应的PUCCH满足预定义的时间线(timeline)的一个SPS PDSCH接收。假设第一集合中SPS PDSCH#m所对应的配置的用于HARQ-ACK反馈的PUCCH资源为PUCCH m。另外，SPS PDSCH#m所对应的PDSCH的结束时域位置(符号/时隙/子时隙)为

另外，SPS PDSCH#m所对应的用于承载相应HARQ-ACK信息的PUCCH起始时域位置(符号/时隙/子时隙)为
Figure PCTCN2019100868-appb-000013
当
Figure PCTCN2019100868-appb-000014
终端设备可以根据PUCCH i发送第一反馈信号。其中，T为一个预定义阈值，例如与N 2timeline相同，也即等同于PDSCH传输与相应HARQ-ACK反馈之间的最小时域间隔，该阈值与UE上报的能力和/或(相应的上行)子载波间隔(SCS，Sub-carrier Spacing)相关。
再例如，该第一上行资源所对应的SPS PDSCH接收可以是上述第一集合中的SPS PDSCH接收对应的PUCCH容量(capacity)大于或等于相应的总负载大小 (payload size)的一个SPS PDSCH接收。假设第一集合中SPS PDSCH#m所对应的配置的用于HARQ-ACK反馈的PUCCH资源为PUCCH m。另外，SPS PDSCH#m所对应的HARQ信息比特数为N m。另外，SPS PDSCH#m所对应的用于承载相应HARQ-ACK信息的PUCCH的容量为C m，当
Figure PCTCN2019100868-appb-000015
终端设备可以根据PUCCH i发送第一反馈信号。
在这个例子中，如果没有PUCCH的容量大于或等于总负载大小，则终端设备可以根据容量最大的PUCCH资源发送第一反馈信号。也即，该第一上行资源所对应的SPS PDSCH接收可以是上述第一集合中的SPS PDSCH接收对应的PUCCH容量(capacity)最大的一个SPS PDSCH接收。即如果在第一集合中的SPS PDSCH没有对应的满足上述条件的PUCCH m，则终端设备可以根据PUCCH i’发送第一反馈信号，其中
Figure PCTCN2019100868-appb-000016
在本申请实施例中，上述PUCCH的容量与PUCCH资源的时频域资源大小、调制方式、和/或码率有关，本申请不限于此。
在本申请实施例中，在操作502的至少一个实施例中，终端设备可以使用(或根据)第二上行资源发送上述第一反馈信号，该第二上行资源属于第二集合，该第二上行资源与第一集合中的SPS PDSCH接收所对应的HARQ-ACK信息的大小相关。
以第二上行资源为PUCCH资源为例，则第二集合可以包括{PUCCH#1，PUCCH#2，…，PUCCH#K}，其中，一个元素记为PUCCH#k，k＝1，2，3，…，K，(K>＝1)。并且，例如，第二集合中的上行资源可以按照资源容量升序或降序排列。
例如，假设第一集合中SPS PDSCH#m所对应的HARQ反馈比特数为N m。另外，PUCCH#k所对应的PUCCH资源容量为C k，当

再例如，假设第二集合{PUCCH#1，PUCCH#2，…，PUCCH#K}所对应的payload size范围分别为PUCCH#1→{P0，P1}，PUCCH#2→{P 1，P 2}，…，PUCCH#K→{P K-1，P K}。当

Figure PCTCN2019100868-appb-000020
在本申请实施例中，上述第二上行资源可以通过RRC信令指示，也即，终端设 备可以根据RRC信令使用上述第二上行资源发送第一反馈信号。该RRC信令是指示终端设备使用第二集合中的上行资源传输第一集合中SPS PDSCH接收所对应的HARQ-ACK信息。例如，该RRC信令的IE名称为‘SPS-HARQ-multiplexing-PUCCH’，其可以被配置为使能(enable)或去使能(disabled)或不被配置(例如，不被配置等同于去使能)。在该RRC使能的条件下，终端设备可以根据所述第二集合中的上行资源传输所述第一集合中SPS PDSCH接收所对应的HARQ信息；如果该RRC信令的指示为去使能，则终端设备需要根据与SPS PDSCH接收相对应的HARQ PUCCH资源发送所述第一反馈信号，具体的实施方法如前所述。
在本申请实施例中，在操作502的至少一个实施例中，终端设备可以根据RRC信令发送第一反馈信号。例如，该RRC信令的使能状态表示，终端设备允许将同一个BWP上的至少两个SPS PDSCH对应的反馈信息在相同的上行资源中复用。例如，该RRC信令的IE名称为‘SPS-HARQ-multiplexing’，其可以被配置为使能或去使能或不被配置(例如，不被配置等同于去使能)。也即，当RRC信令指示相应的使能状态时，终端设备可以发送第一反馈信号；如果为去使能时(或没有被配置时)，终端设备不能发送所述第一反馈信号。
在本申请实施例中，在操作502的至少一个实施例中，终端设备可以根据已上报的(reported)终端设备能力(UE capability)发送第一反馈信号。该能力是指终端设备能够将同一个BWP上的至少两个SPS PDSCH对应的反馈信息在相同的上行资源中复用。该能力可以是关于终端设备所有CC/服务小区的，或者该能力是每个CC/serving cell分别上报的，本申请不限于此。当终端设备拥有该能力并将相应的信息上报给网络设备时，终端设备可以按照文中所述方法发送第一反馈信号。
根据本申请实施例的以上方法选择用于承载上述反馈信息的上行资源(上行信号)，使得该反馈信息能够在时频大小合适的上行信号进行传输，保证了传输的可靠性，从而提升了系统的性能。
通过本申请实施例的方法，网络设备可以更灵活地在同一个BWP/CC/serving cell/相同serving cell的相同BWP中配置多个SPS(更灵活的周期、起始位置)，而且还能够降低SPS传输反馈信息的时延。

在本申请实施例中，SPS PDSCH发送是指：网络设备能够(可以)根据已发送的SPS激活DCI的指示内容以及相应的SPS配置信息发送相应的PDSCH。需要说明的是，网络设备不一定发送了上述PDSCH，但终端设备会在相应的位置监听/接收PDSCH。
在本申请实施例中，在操作601中，网络设备会向终端设备发送SPS配置信息，关于该SPS配置信息的内容和发送方式，本申请不作限制，可以参考相关技术。
在本申请实施例中，第三集合中的SPS PDSCH发送对应相同的HARQ-ACK码本。
在至少一个实施例中，第三集合中的SPS PDSCH发送对应相同的HARQ-ACK码本是指：所述第三集合中的SPS PDSCH发送所对应的SPS配置的HARQ-ACK码本标识相同；或者，所述第三集合中的SPS PDSCH发送所对应的SPS激活DCI中的HARQ-ACK码本标识相同。
在本申请实施例中，第二反馈信号包括第三集合中的SPS PDSCH发送所对应的HARQ-ACK信息，并且，第三集合中的SPS PDSCH发送所对应的反馈信息在第三反馈信号中的顺序与以下至少一种方式相关：
