下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的反馈资源确定方法、装置、通信设备、系统及存储介质进行详细地说明。
NR技术已经历经了两个版本Rel-15和Rel-16的演进，但这两个版本中均未支持多播/广播特性，然而在很多重要的使用场景中，例如，在公共安全和关键任务(即public safety and mission critical)、车用无线通信技术(vehicle to X，V2X)应用,透明IPv4/IPv6多播传送(即transparent IPv4/IPv6multicast delivery)、IPTV(即交互式网络电视)、无线软件传送(即software delivery over wireless)、组通信和物联网应用(即group communications and IoT applications)等中，多播/广播特性可以提供实质性的提高，尤 其是在系统效率和用户体验方面。因此，在接下来的Rel-17版本中，NR将引入广播/多播特性。
目前，在NR的多播传输中，支持点到多点(point to multipoint，ptm)方式的多播业务发送，由G-RNTI(即group RNTI)加扰的物理下行控制信道(Physical downlink control channel，PDCCH)调度G-RNTI加扰的物理下行共享信道(Physical downlink shared channel，PDSCH)来进行业务调度和传输。G-RNTI加扰的PDCCH或PDSCH可以同时被一组终端接收。
UE在接收并解码基站传输的PDSCH，或PDCCH(例如指示半静态调度(Semi-Persistent Scheduling，SPS)PDSCH释放的PDCCH等)之后，可以要向基站侧反馈该PDSCH/PDCCH的解码结果，以告知基站是否成功解码出该PDSCH/PDCCH。从而基站在接收到该解码结果之后，可以根据该解码结果进行下一步的调度决策，这一过程称为HARQ。在多播传输中，HARQ-ACK反馈方式有HARQ-ACK/NACK(即混合自动重传请求确认/否定确认)和HARQ NACK ONLY，在HARQ-ACK/NACK反馈方式中，UE若成功解码PDSCH/PDCCH，则反馈ACK；UE若未成功解码PDSCH/PDCCH，则反馈NACK。在HARQ NACK ONLY反馈方式中，UE在成功解码PDSCH/PDCCH时不反馈NACK，在未成功解码PDSCH/PDCCH时反馈NACK信息。
NR中可以通过下行控制信息(Downlink Control Information，DCI)指示的k1，确定反馈HARQ的时间单元(例如，时隙或子时隙)，其中k1表示从PDSCH结束位置所在的时间单元到HARQ反馈的时间单元的时间单元数量，例如，若UE在时间单元n接收到PDSCH，则UE将在时间单元n+k1反馈其对应的HARQ信息。对于不同的PDSCH，k1可以取不同的值，基站可以先通过无线资源控制(Radio Resource Control，RRC)信令配置k1集合，然后通过DCI指示具体的值，如果DCI中没有k1域，则通过高层参数确定。
PUCCH是承载HARQ信息的主要信道。对于ACK/NACK反馈方式，其PUCCH是UE特定的，即不同UE的PUCCH不同。对于NACK ONLY反馈方式，其PUCCH可以是组公共的，即不同的UE可以在相同的PUCCH上反馈同一个PDSCH的NACK信息。
NR中对于动态调度的单播PDSCH或者动态调度的反馈模式为HARQ-ACK/NACK的多播PDSCH，对于HARQ-ACK反馈的PUCCH资源的确定，是先通过反馈的HARQ-ACK比特数在预配置的多个PUCCH资源集合中确定一个PUCCH资源集合，然后在该PUCCH集合内，通过调度PDSCH的DCI中的PUCCH资源指示(PUCCH resource indicator，PRI)和控制信道单元索引(Control Channel Element index，CCE index)确定传输HARQ-ACK的PUCCH资源索引。对于仅包含SPS PDSCH HARQ-ACK的单播反馈，如果UE没有被配置多个用于反馈SPS PDSCH HARQ-ACK的PUCCH，即SPS-PUCCH-AN-List，那么UE在预配置的PUCCH(即参数n1PUCCH-AN配置)上反馈SPS HARQ-ACK，如果UE被配置了多个用于反馈SPS PDSCH HARQ-ACK的PUCCH，那么UE根据反馈的HARQ-ACK比特数，在基站配置的反馈SPS PDSCH HARQ-ACK的多个PUCCH资源中确定一个PUCCH资源，以传输SPS HARQ-ACK。对于动态调度的多播PDSCH的HARQ-ACK，如果其反馈方式是NACK ONLY，那么UE可以根据HARQ-ACK的比特状态和PUCCH资源之间的映射关系，从如下表1所示的预定义表格中确定反馈HARQ-ACK的PUCCH。
表1
然而，按照上述方法，在HARQ NACK ONLY反馈方式中，UE仅可以根据预定义表格确定反馈HARQ-ACK的PUCCH资源，而基站无法灵活指示不同的反馈资源，会造成一定的调度限制。另外，对于多播SPS PDSCH的NACK ONLY反馈，其反馈资源确定的方式尚不明确。从而导致确定反馈资源的有效性问题。
为了解决上述问题，在本申请实施例提供的反馈资源确定方法中，UE可以从网络侧设备接收第一下行信道；且可以根据第一信息确定反馈资源，反馈资源用于UE发送第一下行信道的反馈信息；其中，第一信息指示以下至少一项：反馈信息的比特数；反馈信息的反馈模式；第一下行信道的信道类型。通过该方案，由于UE在从网络侧设备接收到第一下行信道之后，可以根据反馈信息的比特数、反馈信息的反馈模式，以及第一下行信道的信道类型中的至少一项，确定发送第一下行信道的反馈信息的反馈资源，因此无论对于HARQ NACK ONLY反馈方式，还是对于包括SPS PDSCH的反馈方式，均可以提高确定反馈资源的灵活性。
本申请实施例提供一种反馈资源确定方法，图2示出了本申请实施例提供的反馈资源确定方法的流程图。如图2所示，本申请实施例提供的反馈资源确定方法可以包括下述的步骤201和步骤202。

本申请实施例中，第一信息包括以下至少一项：
(1.1)上述反馈信息的比特数；
(1.2)该反馈信息的反馈模式；
(1.3)第一下行信道的信道类型。
可选地，本申请实施例中，上述反馈信息的反馈模式可以为第一模式或第二模式。
可选地，本申请实施例中，第一模式(即mode1)可以为：UE在一个PUCCH上传输多个NACK ONLY反馈时，通过将NACK ONLY转换为ACK/NACK比特进行反馈的反馈模式；第二模式(即mode2)可以为：UE在一个PUCCH上传输多个NACK ONLY反馈时，UE传输一个对应于多个NACK ONLY反馈组合的特定序列或者PUCCH，例如UE通过PUCCH资源选择传输多个NACK ONLY反馈。
可选地，本申请实施例中，信道类型可以为：单播动态调度类型、单播半静态调度类型、多播动态调度类型或多播半静态调度类型等。其中单播动态调度类型即表示动态调度的单播PDSCH(例如C-RNTI加扰的PDCCH调度的)，单播半静态调度类型即表示半静态调度(SPS)的单播PDSCH(例如CS-RNTI加扰的PDSCH)，多播动态调度类型即表示动态调度的多播PDSCH(例如G-RNTI加扰的PDCCH调度的)，多播半静态调度类型即表示半静态调度(SPS)的多播PDSCH(例如G-CS-RNTI加扰的PDSCH)。
对UE根据第一信息确定反馈资源的具体方法，将在下述的实施例中进行详细地说明，为了避免重复，此处不予赘述。
在本申请实施例提供的反馈资源确定方法中，由于UE在从网络侧设备接收到第一下行信道之后，可以根据反馈信息的比特数、反馈信息的反馈模式，以及第一下行信道的信道类型中的至少一项，确定发送第一下行信道的反馈信息的反馈资源，因此可以提高确定反馈资源的灵活性。
可选地，本申请实施例中，第一信息包括：上述反馈信息的比特数，或反馈信息的反馈模式；那么上述步骤202具体可以通过下述的步骤202a实现。
步骤202a、在第一下行信道对应的反馈方式为NACK ONLY反馈方式的情况下，UE根据第一信息确定反馈资源。
本申请实施例中，上述反馈方式为UE发送上述反馈信息的方式。
可选地，本申请实施例中，上述反馈方式可以包括：NACK ONLY反馈方式或ACK/NACK反馈方式。
可选地，本申请实施例中，在第一下行信道对应的反馈方式为ACK/NACK反馈方式的情况下，UE可以通过相关技术中的具体方法确定反馈资源。
对NACK ONLY反馈方式、ACK/NACK反馈方式以及ACK/NACK反馈方式对应的反馈资源确定方法的具体描述，可以参照上述相关技术中的相关描述，为了避免重复，此处不予赘述。
本申请实施例中，由于UE在第一下行信道对应的反馈方式为NACK ONLY反馈方式的情况下，可以根据反馈信息的比特数、反馈信息的反馈模式，以及第一下行信道的信道类型中的至少一项，确定发送第一下行信道的反馈信息的反馈资源，因此可以提高NACK ONLY反馈方式下确定反馈资源的灵活性以及有效性。
下面对UE根据第一信息确定反馈资源的具体方法进行详细说明。
可选地，本申请实施例中，第一信息包括：上述反馈信息的比特数，或反馈信息的反馈模式；那么上述步骤202具体可以通过下述的步骤202b或步骤202c实现。
步骤202b、若第一信息满足第一条件，则UE根据DCI的指示确定反馈资源。
可选地，本申请实施例中，上述DCI可以为第一下行信道对应的最后一个DCI(即 last DCI)。
可选地，本申请实施例中，第一条件可以包括以下至少一项：反馈信息的比特数为1；反馈模式被配置为第一模式；反馈模式未被配置为第二模式。
可选地，本申请实施例中，上述反馈模式未被配置为第二模式，可以理解为：该反馈模式的默认模式为第一模式，或者该反馈模式被配置为第一模式。
可选地，本申请实施例中，上述反馈模式可以通过高层参数例如moreThanOneNackOnlyMode配置。
步骤202c、若第一信息满足第二条件，则UE根据反馈信息的比特数、反馈信息的比特状态和第一映射关系，确定反馈资源。
本申请实施例中，第一映射关系为：上述反馈信息的比特数、反馈信息的比特状态与上述反馈资源之间的映射关系。
可选地，本申请实施例中，每个反馈信息的比特数、反馈信息的比特状态与一个反馈资源之间可以存在一个映射关系。
可选地，本申请实施例中，UE可以根据上述映射关系从上表1中确定反馈资源。
可选地，本申请实施例中，第二条件可以包括以下至少一项：反馈信息的比特数大于1；反馈模式未被配置为第一模式；反馈模式被配置为第二模式。
可选地，本申请实施例中，上述反馈模式未被配置为第一模式，可以理解为：如果高层参数例如moreThanOneNackOnlyMode的默认值为第二模式，当基站配置该参数时，表示上述反馈模式被配置为第一模式，当基站未配置该参数时，表示上述反馈模式被配置为第二模式，或者该反馈模式被配置为第二模式。
本申请实施例中，由于在第一信息满足第一条件的情况下，UE可以根据DCI的指示确定反馈资源，在第一信息满足第二条件的情况下，UE可以根据反馈信息的比特数、反馈信息的比特状态和第一映射关系，确定反馈资源，即第一信息在满足不同的条件时，UE可以通过不同的方式确定反馈资源，因此可以进一步提高确定反馈资源的灵活性。
可选地，本申请实施例中，第一信息包括：上述反馈信息的比特数；那么上述步骤202具体可以通过下述的步骤202d实现。
步骤202d、UE根据反馈信息的比特数、反馈信息的比特状态和第一映射关系，从第一资源子集合中确定反馈资源。
本申请实施例中，第一资源子集合根据DCI和/或该DCI对应的CCE index确定。
本申请实施例中，第一映射关系为：上述反馈信息的比特数、反馈信息的比特状态与上述反馈资源之间的映射关系。
可选地，本申请实施例中，上述DCI可以为调度/激活所述第一下行信道(例如PDSCH)的DCI，或者所述第一下行信道(例如PDCCH)承载的DCI。进一步的，所述DCI为所述第一下行信道对应的最后一个DCI。例如按照特定规则(例如服务小区索引，CORESET poo index，PDCCH检测时机等)，对所述第一下行信道对应的多个DCI进行排序得到的last DCI。
可选地，本申请实施例中，可以先将反馈资源(例如PUCCH)集合中的反馈资源分为不同资源组/子集合，然后UE可以根据DCI和/或该DCI对应的CCE index，确定第一资源子集合，从而UE可以根据反馈信息的比特数、反馈信息的比特状态和第一映射关系，从第一资源子集合中确定上述反馈资源。
示例性地，假设反馈资源集合(例如PUCCH resource set)中包含的反馈资源个数为X,将该反馈资源集合分成的不同的组，每组反馈资源中包括的反馈资源的个数为Y或者不少于Y,例如如果X为Y的整数倍，则每组中刚好包含Y个，如果X不是Y 的整数倍，可以在前面的组中每组包含Y个，在最后一组中包含多于Y个,那么分成的反馈资源集合数Z为X/Y或者floor(X/Y)，其中Y与HARQ-ACK比特数有关，例如，(1)若HARQ-ACK比特数为1，则Y＝1；(2)若HARQ-ACK比特数为2，则Y＝3；(3)若HARQ-ACK比特数为3，则Y＝7；(4)若HARQ-ACK比特数为4，则Y＝15；假设上述X为32，对于上述(1)，Z为32，对于上述(2)，Z为10，对于上述(3)，Z为4，对于上述(4)，Z为2。从而UE可以根据Last DCI中的PRI，或者该PRI以及CCE index的指示确定上述反馈资源所在的第一资源子集合，并根据反馈信息的比特数、反馈信息的比特状态和第一映射关系，通过下表2，从第一资源子集合(例如下表2中的the determined subset)中确定该反馈资源。
表2
本申请实施例中，由于在第一信息包括上述反馈信息的比特数时，UE可以根据反馈信息的比特数、反馈信息的比特状态和第一映射关系，从第一资源子集合中确定上述反馈资源，因此可以避免UE从所有反馈资源中确定该反馈资源，从而可以减少UE的功耗，并简化确定反馈资源的过程。
对于NACK ONLY反馈方式，以上述反馈资源为PUCCH资源为例，其PUCCH 资源由参数pucch-ConfigurationListMulticast2配置，其中pucch-ConfigurationListMulticast2可以配置最多2个PUCCH-config，若pucch-ConfigurationListMulticast2配置了2个PUCCH-config，则第一个PUCCH-config和第二个PUCCH-config分别配置用于反馈优先级索引为0和1的HARQ-ACK反馈。在每个PUCCH-config内可以配置一个PUCCH资源集合，该资源集合内可以配置最多32个PUCCH资源，每个PUCCH资源的格式为PUCCH格式0或格式1。对于现有的根据PRI指示的资源确定方法只适用于ACK/NACK反馈，无法适用于NACK ONLY多比特反馈(此时有多个状态，每个状态对应不同的PUCCH，UE需要根据HARQ-ACK反馈的比特状态确定反馈的PUCCH资源，如果仅根据PRI确定，则基站无法知道反馈的HARQ-ACK的比特状态)。同时，仅根据现有的资源确定的表格(例如上表1)，基站无法灵活指示UE反馈HARQ-ACK的PUCCH资源。为此，采用上述步骤202d确定上述反馈资源可以避免上述问题，从而可以增加通信系统的灵活性和有效性。
可选地，本申请实施例中，第一信息包括：第一下行信道的信道类型；那么上述步骤202具体可以通过下述的步骤202e或步骤202f实现。

可选地，本申请实施例中，第三信息包括：上述反馈信息的比特数、反馈信息的比特状态和第一映射关系；那么上述步骤202f具体可以通过下述的步骤202f1实现。
