具体实施方式
下文中将结合附图对本申请的实施例进行说明。在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
随着第五代移动通信技术(5G，The 5th Generation Mobile Communication Technology)的发展，5G系统致力于满足更高速率(Gbps)、巨量链接(1M/Km2)、超低时延(1ms)、更高的可靠性、百倍的能量效率提升等技术指标，以支撑新的需求变化。其中，5G也可以称为新空口(New Radio，NR)。基于NR的非授权频谱接入(NR-based Access to Unlicensed Spectrum，NR-U)技术在物联网、工厂自动化等各方面的应用前景，NR-U还面临诸多问题需要解决。
对于非授权频谱的使用，遵循一定的管制政策。比如，设备在使用非授权载波发送数据之前执行先听后说(Listen Before Talk，LBT)，LBT执行成功的设备可以在非授权载波上发送业务数据。其中，先听后说也可以称为空闲信道评估(Clear Channel Assessment，CCA)。NR与NR-U均支持上行免调度传输(即自主传输)，与NR不同，在NR-U中使用免调度传输资源初次传输物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)数据，若基站解码该PUSCH数据错误，UE可以利用免调度传输资源对该PUSCH数据进行重传，此时，针对该重传特性需要引入显式的解码反馈信息。
目前，在NR-U中，针对免调度上行传输的解码反馈，是一个亟待解决的 问题，特别是在传输TB的基础上，又引入了CBG传输的支持，需要确定针对免调度传输的下行反馈方案。本发明实施例针对免调度传输的下行反馈需求，对下行反馈指示(Downlink Feedback Indicator，DFI)所包含的参数信息，以及对不同调度粒度(包括TB，和/或CBG)的联合解码反馈提供了可行的方案。
图1是本申请实施例提供的一种反馈信息的发送方法的流程图。本实施例适用于对不同调度粒度的联合解码反馈的情况，本实施例可通过基站来执行。
如图1所示，本实施例提供的方法包括S120-S140。
S120、接收用户终端UE发送的业务数据。
S140、向UE发送业务数据对应的下行反馈指示DFI信息。
其中，DFI信息包括混合自动重传请求(Hybrid Automation Repeat Request，HARQ)确认(ACK)/非确认(NACK)指示，HARQ ACK/NACK指示用于指示基站对业务数据中传输块TB和/或码块组CBG的解码结果。
其中，业务数据可以为PUSCH数据，也可以为物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)数据。在一实施例中，UE用于向基站发送业务数据，而基站向UE反馈DFI信息，即在实施例中，业务数据包括PUSCH数据。在业务数据中可以通过不同调度粒度进行数据传输，比如，可以通过TB的形式进行数据传输，也可以通过CBG的形式进行数据传输。基站为UE配置上行免调度资源和免调度传输所使用的HARQ进程范围，UE可以利用上行免调度资源和HARQ进程传输PUSCH数据，基站在免调度资源接收并解码免调度传输的PUSCH数据，基站根据PUSCH数据的接收和解码结果为UE反馈DFI信息。其中，HARQ进程范围指的是基站预先为UE免调度传输所配置的HARQ进程的有效范围，即在HARQ进程范围的HARQ进程，才可以用于免调度业务数据的传输。其中，DFI信息为下行链路控制信息(Downlink Control Information， DCI)的一种，且DFI的比特域开销与当前DCI格式中的一种DCI的比特域开销保持一致。在一实施例中，DFI信息至少还包括下述一项：DCI用途标示、载波指示、带宽部分(BandWidth Part，BWP)指示、预编码信息指示、传输功率控制(Transmit Power Control，TPC)指示、调制编码策略(Modulation and Coding Scheme，MCS)和秩指示(Rank Indicator，RI)；DCI用途标示用于指示DCI当前所表示的用途为DFI反馈或激活/去激活上行免调度资源；载波指示用于指示DCI对载波索引所对应的载波有效；BWP指示用于指示DCI对BWP索引所对应的BWP有效。DCI用途标示用于区分该DCI用于DFI反馈，还是用于激活/去激活上行免调度资源；载波指示应用于多载波调度，用于指示该DCI对具体的载波索引所对应的载波有效；BWP指示应用于多BWP调度或BWP切换过程，用于指示该DCI对具体的BWP索引所对应的BWP有效。
在一实施例中，反馈信息的发送方法，还包括：确定业务数据的接收完成与DFI信息准备完成之间的时间间隔；根据时间间隔确定DFI信息的反馈有效性。在一实施例中，根据时间间隔确定DFI信息的反馈有效性，包括：针对一个HARQ进程，在时间间隔大于等于N个符号或时隙slot的情况下，针对所述HARQ进程的DFI信息为有效反馈；针对一个HARQ进程，在时间间隔小于N个符号或slot的情况下，针对所述HARQ进程的DFI信息为无效反馈，其中，N通过无线资源控制(Radio Resource Control，RRC)信令配置或根据物理上行共享信道PUSCH传输的子载波间隔确定。在实施例中，UE使用免调度资源和HARQ进程发送PUSCH数据至基站，在UE完成PUSCH数据传输之后的N个符号或时隙slot内，针对HARQ进程的DFI反馈为无效反馈，换句话说，UE使用HARQ进程发送PUSCH数据，在完成PUSCH数据的发送与开始反馈DFI信息之间的时间间隔不小于N个符号或者slot，则DFI针对所述HARQ进程的 HARQ ACK/NACK反馈是有效的，UE可以根据HARQ ACK/NACK反馈信息确定HARQ进程的PUSCH解码结果；UE使用HARQ进程发送PUSCH数据，完成PUSCH数据的发送与DFI反馈之间的时间间隔小于N个符号或者slot，则DFI针对所述HARQ进程的HARQ ACK/NACK反馈是无效的，UE不能根据HARQ ACK/NACK反馈确定HARQ进程的PUSCH解码结果。其中，N的取值可以通过RRC信令配置，也可以根据PUSCH传输的子载波间隔确定，对此并不进行限定。
在一实施例中，HARQ ACK/NACK指示至少包括下述一项：HARQ进程所对应TB级的解码反馈指示信息，以及HARQ进程所对应CBG级的解码反馈指示信息。在实施例中，基站为UE配置上行免调度资源和免调度传输所使用的HARQ进程范围，UE可以利用上行免调度资源和HARQ进程传输PUSCH数据，基站在免调度资源接收并解码免调度PUSCH数据的传输，基站根据PUSCH数据的接收和解码结果为UE反馈DFI信息，其中，DFI信息包含HARQ ACK/NACK指示，HARQ ACK/NACK指示信息针对HARQ进程解码结果进行反馈指示，该HARQ ACK/NACK指示至少包含以下信息之一：针对HARQ进程的TB级解码反馈指示信息，以及针对HARQ进程的CBG级解码反馈指示信息。其中，针对HARQ进程的TB级解码反馈指示信息，指的是基站对HARQ进程中所传输的TB接收和解码结果的反馈信息；针对HARQ进程的CBG级解码反馈指示信息，指的是基站对HARQ进程中所传输的CBG接收和解码结果的反馈信息。其中，一个TB可以包含一个或多个CBG。
在一实施例中，PUSCH数据包括：上行控制信息UCI，UCI包含上行链路分配索引(Uplink Assignment Index，UAI)，UAI用于统计UE所发送的PUSCH数据。在一实施例中，反馈信息的发送方法，还包括：根据UAI确定PUSCH 数据的漏检情况。在实施例中，UE在利用上行免调度资源传输PUSCH数据时，携带上行控制信息(Uplink Control Information，UCI)，UCI包含类似下行链路分配索引(Downlink assignment index，DAI)的上行链路分配索引(Uplink Assignment index，UAI)，UAI用于统计UE所发送的PUSCH数据，基站根据该信息确定是否有PUSCH数据的漏检，针对漏检HARQ进程的PUSCH数据，在HARQ ACK/NACK反馈时传输解码反馈为NACK。示例性地，UAI统计UE通过HARQ进程1、2、3和4发送PUSCH数据至基站，但基站接收到了使用HARQ进程1、3和4所传输的PUSCH数据，即使用HARQ进程2传输的PUSCH数据出现漏检情况。基站针对HARQ进程2的PUSCH数据，在HARQ ACK/NACK反馈时传输解码反馈为NACK。
基站接收到UE在上行免调度资源上传输的PUSCH数据之后，针对解码正确的HARQ进程反馈TB级的ACK信息，针对解码错误以及漏检的HARQ进程反馈TB级的NACK信息，针对CBG级的ACK/NACK反馈可以包括下述方案之一：
在一实施例中，HARQ ACK/NACK指示至少包括下述一项：第一HARQ进程集合所对应TB级的ACK/NACK信息，以及第一HARQ进程集合所对应CBG级的ACK/NACK信息；第一HARQ进程集合包括：UE免调度传输所使用的一个或多个HARQ进程。在实施例中，第一HARQ进程集合中的所有HARQ进程均为UE当前免调度传输所使用的一个或多个HARQ进程，即在第一HARQ进程集合中可以包括一个HARQ进程，也可以包括多个HARQ进程，其第一HARQ进程集合中所包括的HARQ进程数量与UE免调度传输使用的HARQ进程个数有关。在HARQ ACK/NACK指示中至少包括下述一项：第一HARQ进程集合所对应TB级的ACK/NACK信息，以及第一HARQ进程集合所对应CBG 级的ACK/NACK信息。
在一实施例中，HARQ ACK NACK指示中只包括第一HARQ进程集合所对应TB级的ACK/NACK信息，即针对UE用于免调度传输所使用的一个或多个HARQ进程，基站仅反馈TB级的ACK/NCAK信息，不反馈CBG级的ACK/NACK信息。示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可拆分的CBG数配置为4，其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确。针对TB级ACK/NACK反馈为1000，即不反馈CBG级的ACK/NACK信息。
在一实施例中，HARQ ACK NACK指示中只包括第一HARQ进程集合所对应CBG级的ACK/NACK信息，即针对UE用于免调度传输所使用的一个或多个HARQ进程，基站仅反馈CBG级的ACK/NACK信息，不反馈TB级的ACK/NACK信息。示例性地，基站为UE免调度传输配置的进程为1-8，每个TB可以拆分的CBG数量配置为4个，即每个TB可以拆分为4个CBG。其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，即第一HARQ进程集合包括：HARQ进程2、5、7和8。其中，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中，TB_3的CBG_1和CBG_4解码错误，TB_3的CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中，TB_4的CBG_3解码错误，其余CBG解码正确，则针对HARQ进程2、5、7和8的CBG级ACK/NACK反馈为1111000001101101，即HARQ ACK/NACK反馈结果为1111000001101101，共计 16比特。图2是本申请实施例提供的一种CBG级ACK/NACK联合反馈示意图。如图2所示，TB_1的CBG级ACK/NACK反馈为1111，TB_2的CBG级ACK/NACK反馈为0000，TB_3的CBG级ACK/NACK反馈为0110，TB_4的CBG级ACK/NACK反馈为1101。
在一实施例中，HARQ ACK/NACK指示中包括：第一HARQ进程集合所对应TB级的ACK/NACK信息，以及第一HARQ进程集合所对应CBG级的ACK/NACK信息。换句话说，针对UE用于免调度传输所使用的一个或多个HARQ进程，基站同时反馈TB级的ACK/NACK信息和CBG级的ACK/NACK信息。示例性地，基站为UE免调度传输配置的进程为1-8，每个TB可以拆分的CBG数配置为4，即每个TB可以拆分为4个CBG。其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，即第一HARQ进程集合包括：HARQ进程2、5、7和8。其中，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中，TB_3的CBG_1和CBG_4解码错误，TB_3的CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中，TB_4的CBG_3解码错误，其余CBG解码正确，则针对HARQ进程2、5、7和8的TB级ACK/NACK反馈为1000，以及针对HARQ进程2、5、7和8的CBG级ACK/NACK反馈为1111000001101101，即HARQ ACK/NACK反馈结果为10001111000001101101，共计20比特。图3是本申请实施例提供的一种TB级ACK/NACK与CBG级ACK/NACK联合反馈示意图。如图3所示，针对HARQ进程2、5、7和8的TB级ACK/NACK反馈为1000，针对HARQ进程的TB_1的CBG级ACK/NACK反馈为1111，TB_2的CBG级ACK/NACK反馈为0000，TB_3的CBG级ACK/NACK反馈为0110，TB_4的CBG级ACK/NACK反馈为1101。
在一实施例中，HARQ ACK/NACK指示包括：第一HARQ进程集合所对应TB级的ACK/NACK信息，以及第二HARQ进程集合所对应CBG级的ACK/NACK信息；第一HARQ进程集合包括：UE免调度传输所使用的一个或多个HARQ进程，第二HARQ进程集合为第一HARQ进程集合中TB级反馈为NACK的全部HARQ进程。在实施例中，在第一HARQ进程集合中存在TB级反馈为NACK的HARQ进程的情况下，第二HARQ进程集合中包括的HARQ进程至少为一个；在第一HARQ进程集合中不存在TB级反馈为NACK的HARQ进程的情况下，第二HARQ进程集合中包括的HARQ进程个数为零，即第一HARQ进程集合中的所有HARQ进程所对应TB级反馈均为ACK。针对UE用于免调度传输所使用的HARQ进程，基站对TB级反馈为NACK的所有HARQ进程，同时反馈CBG级的ACK/NACK信息；基站接收到HARQ进程的PUSCH数据传输，则CBG级的ACK/NACK信息根据CBG级的解码结果进行反馈，解码正确反馈ACK，解码错误反馈NACK；基站漏检HARQ进程的PUSCH数据传输，则CBG级的ACK/NACK信息反馈均为NACK。示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4，即每个TB可拆分为4个CBG，其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确，则针对TB级ACK/NACK反馈为1000，针对CBG级ACK/NACK反馈为0000 01101101，即HARQ ACK/NACK反馈结果为1000 0000 0110 1101，共计16比特。图4是本申请实施例提供的另一种TB级ACK/NACK与CBG级ACK/NACK联合反馈示意图。如 图4所示，针对HARQ进程2、5、7和8的TB级ACK/NACK反馈为1000，针对HARQ进程的TB_2的CBG级ACK/NACK反馈为0000，TB_3的CBG级ACK/NACK反馈为0110，TB_4的CBG级ACK/NACK反馈为1101。
在一实施例中，HARQ ACK/NACK指示包括：第一HARQ进程集合所对应TB级的ACK/NACK信息，以及第三HARQ进程集合所对应CBG级的ACK/NACK信息；第一HARQ进程集合包括：UE免调度传输所使用的一个或多个HARQ进程，第二HARQ进程集合为第一HARQ进程集合中TB级反馈为NACK的全部HARQ进程，第三HARQ进程集合为第二HARQ进程集合中前第一预设个数的TB级反馈为NACK的HARQ进程。其中，对第二HARQ进程集合的解释见上述实施例的描述，在此不再赘述。其中，第三HARQ进程集合为第二HARQ进程集合中全部HARQ进程的一个子集，该子集中HARQ进程的数量为第一预设个数，并且，该子集中的HARQ进程为前第一预设个数的HARQ进程。示例性地，假设第一HARQ进程集合中包括：HARQ进程2、5、7和8，并且，HARQ进程5、7和8的TB级反馈为NACK，则第二HARQ进程集合包括：HARQ进程5、7和8；假设第一预设个数为2，则第三HARQ进程集合包括：HARQ进程5和7。
针对UE用于免调度传输所使用的HARQ进程，基站针对TB级反馈为NACK的前第一预设个数(比如，记为n个)进程，同时反馈CBG级的ACK/NACK信息；基站接收到HARQ进程的PUSCH数据传输，则CBG级的ACK/NACK信息根据CBG级的解码结果进行反馈，解码正确反馈ACK，解码错误反馈NACK；基站漏检HARQ进程的PUSCH数据传输，则CBG级的ACK/NACK信息反馈均为NACK。其中，前n个进程，可以按HARQ进程编号升序/降序排列，取前n个；也可以按发送时间先后对HARQ进程进行排序，取前n个。其 中，n的取值可以通过以下方法之一确定：
在一实施例中，第一预设个数可以由RRC信息配置。
在一实施例中，第一预设个数为一个默认值。
在一实施例中，第一预设个数由每个TB中的CBG数量进行确定，每个TB中的CBG数量由RRC信令进行配置。在实施例中，n的取值可以通过RRC信令中其它信息隐含指示。比如，可以通过RRC信令中配置每个TB可以拆分的CBG数隐含通知，假设每个TB可以拆分的CBG数为{0，2，4，6，8}，则对应的，n可以取值为{0，8，4，2，2}。示例性地，每个TB可以拆分的CBG数为6，并且，CBG级ACK/NACK反馈比特域开销的最大值为16，则n取值为2；又如，每个TB可以拆分的CBG数为8，并且，CBG比特域开销的最大值为16，则n也可以为2。在一实施例中，在CBG级ACK/NACK反馈比特域开销的最大值为32的情况下，若每个TB可以拆分的CBG数为{0，2，4，6，8}，则对应的，n可以取值为{0，16，8，5，4}。在实施例中，对CBG级ACK/NACK反馈比特域开销的最大值不作限定，其根据实际情况进行调整即可。在一实施例中，TB级反馈为NACK的HARQ进程数量小于n的情况下，不足部分的CBG级别反馈用NACK填充。
示例性地，假设基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4，n的取值为2。其中，UE使用HARQ进程2、5、7、8传输了PUSCH数据，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确，则针对TB级ACK/NACK反馈为1000，针对CBG级ACK/NACK反馈为0000 0110，也即 HARQ ACK/NACK反馈结果为1000 0000 0110，共计12比特。图5是本申请实施例提供的又一种TB级ACK/NACK与CBG级ACK/NACK联合反馈示意图。如图5所示，针对HARQ进程2、5、7和8的TB级ACK/NACK反馈为1000，即HARQ进程5、7和8的TB级反馈均为NACK，在实施例中，n为2，则取TB级反馈为NACK的前2个HARQ进程，即HARQ进程5和7，即针对HARQ进程5所对应TB_2的CBG级ACK/NACK反馈为0000，HARQ进程7所对应TB_3的CBG级ACK/NACK反馈为0110。
在一实施例中，HARQ ACK/NACK指示包括：第一HARQ进程集合所对应TB级的ACK/NACK信息，第一比特位图bitmap，以及第二HARQ进程集合所对应CBG级的ACK/NACK信息；第一HARQ进程集合包括：UE免调度传输所使用的一个或多个HARQ进程，第二HARQ进程集合为第一HARQ进程集合中TB级反馈为NACK的全部HARQ进程的一个子集，第一bitmap用于指示第二HARQ进程集合中所包含的每个HARQ进程与第一HARQ进程中TB级反馈为NACK的全部HARQ进程之间的对应关系。在实施例中，针对UE用于免调度传输所使用的HARQ进程，基站可通过指示信息来指示针对第一HARQ进程集合中的部分HARQ进程反馈CBG级的ACK/NACK信息，指示信息可以通过bitmap实现。在实施例中，可通过第一bitmap直接指示反馈或者不反馈CBG级的ACK/NACK信息的HARQ进程，即第一bitmap中所对应比特为1，则指示针对所对应的HARQ进程反馈CBG级ACK/NACK信息；第一bitmap中所对应比特为0，则指示针对所对应的HARQ进程不反馈CBG级ACK/NACK信息。
示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4，n的取值为2。其中，UE使用HARQ进程2、5、7、8传输了PUSCH，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的 TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确。假设，基站针对HARQ进程7和8反馈CBG级ACK/NACK，则针对TB级ACK/NACK反馈为1000，指示针对进程7和8反馈CBG级ACK/NACK的第一bitmap为0011，针对CBG级ACK/NACK反馈为01101101，即HARQ ACK/NACK反馈结果为1000001101101101，共计16比特。图6是本申请实施例提供的再一种TB级ACK/NACK与CBG级ACK/NACK联合反馈示意图。如图6所示，针对HARQ进程2、5、7和8的TB级ACK/NACK反馈为1000，即HARQ进程5、7和8的TB级反馈均为NACK，在实施例中，假设针对HARQ进程7和8反馈CBG级ACK/NACK信息，则取第一bitmap为0011，即针对HARQ进程7所对应TB_3的CBG级ACK/NACK反馈为0110，HARQ进程8所对应TB_4的CBG级ACK/NACK反馈为1101。其中，第一bitmap用于指示反馈CBG级ACK/NACK的HARQ进程。
在一实施例中，HARQ ACK/NACK指示包括：第一HARQ进程集合所对应TB级的ACK/NACK信息，第二bitmap，第四HARQ进程集合所对应CBG级的ACK/NACK信息；第一HARQ进程集合包括：UE免调度传输所使用的一个或多个HARQ进程，第四HARQ进程集合为第一HARQ进程集合中CBG级反馈为NACK的CBG数量占比低于预设门限值的全部HARQ进程，第二bitmap用于指示第四HARQ进程集合中所包含的每个HARQ进程与第一HARQ进程集合中的HARQ进程之间的对应关系。在实施例中，针对TB级反馈为NACK的HARQ进程，其所对应CBG级的解码反馈为NACK的CBG数量占比超过预设门限值M或所述HARQ进程的PUSCH漏检，针对所述HARQ进程仅反馈 TB级的NACK信息，其它情况则需要反馈CBG级的ACK/NACK信息。示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4，预设门限值为50％。其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中，TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确。基站针对UE免调度所使用的所有HARQ进程反馈HARQ ACK/NACK信息，则针对HARQ进程2、5、7和8的TB级ACK/NACK的反馈为1000，即HARQ进程5、7和8的TB级反馈均为NACK。在实施例中，TB级反馈均为NACK的三个HARQ进程(HARQ进程5、7和8)中，只有HARQ进程8的CBG级反馈为NACK的CBG数量低于50％，即第四HARQ进程集合包括HARQ进程8，该情况下第二bitmap为0001，即针对HARQ进程8反馈CBG级ACK/NACK信息，针对HARQ进程8的CBG级ACK/NACK反馈为1101，而其余TB级反馈为NACK的HARQ进程，不反馈CBG级ACK/NACK信息，最终的HARQ ACK/NACK反馈内容为1000 0001 1101。
在一实施例中，基站为UE配置上行免调度资源和免调度传输所使用的HARQ进程范围，UE可以利用上行免调度资源和HARQ进程传输PUSCH数据，基站在免调度资源接收并解码免调度PUSCH数据的传输，基站根据PUSCH数据的接收和解码结果为UE反馈DFI信息，其中，DFI信息中包含HARQ ACK/NACK指示，HARQ ACK/NACK指示信息针对HARQ进程解码结果进行反馈指示，该HARQ ACK/NACK指示至少包含以下信息之一：针对HARQ进程的TB级解码反馈指示信息、针对HARQ进程的CBG级解码反馈指示信息。
针对所有配置给UE免调度传输的HARQ进程或所有HARQ进程，基站收到UE利用HARQ进程传输的PUSCH数据，则根据所接收到的PUSCH数据的解码结果，针对HARQ进程反馈TB级ACK/NACK信息和CBG级ACK/NACK信息；基站未收到UE利用HARQ进程传输的PUSCH数据，则针对HARQ进程反馈TB级NACK，需要反馈CBG级ACK/NACK时，同时针对HARQ进程的所有CBG反馈CBG级NACK，其中所述所有HARQ进程为UE调度和免调度传输所能使用的最大进程数；针对HARQ进程的TB级ACK/NACK和CBG级ACK/NACK反馈方案可以包括以下之一：
在一实施例中，HARQ ACK/NACK指示至少包括下述一项：第五HARQ进程集合所对应TB级的ACK/NACK信息，以及第五HARQ进程集合所对应CBG级的ACK/NACK信息；第五HARQ进程集合包括：所有HARQ进程，或者为UE免调度传输所配置的一个或多个HARQ进程，所述所有HARQ进程为UE调度和免调度传输所能使用的最大进程数。
在一实施例中，HARQ ACK/NACK指示包括：第五HARQ进程集合所对应TB级的ACK/NACK信息，即针对所有HARQ进程，或者所有配置给UE免调度传输的HARQ进程，基站仅反馈TB级ACK/NACK信息，不反馈CBG级的ACK/NACK信息。
在一实施例中，HARQ ACK/NACK指示包括：第五HARQ进程集合所对应CBG级的ACK/NACK信息，即针对所有HARQ进程，或者所有配置给UE免调度传输的HARQ进程，基站仅反馈CBG级ACK/NACK信息，不反馈TB级的ACK/NACK信息。

在一实施例中，HARQ ACK/NACK指示包括：第三bitmap，第六HARQ进程集合所对应TB级的ACK/NACK信息，以及第七HARQ进程集合所对应CBG级的ACK/NACK信息；第五HARQ进程集合包括：所有HARQ进程，或者为UE免调度传输所配置的一个或多个HARQ进程，所有HARQ进程为UE调度和免调度传输所能使用的最大进程数，第六HARQ进程集合为第五HARQ进程集合中基站接收到PUSCH数据所对应的一个或多个HARQ进程，第七HARQ进程集合为第六HARQ进程集合中TB级反馈为NACK的一个或多个HARQ进程，第三bitmap用于指示第六HARQ进程集合中所包含的第五HARQ进程集合中的一个或多个HARQ进程。在实施例中，基站针对接收到PUSCH数据的HARQ进程，基站基于解码结果反馈HARQ进程的TB级ACK/NACK，针对所有TB级反馈为NACK的HARQ进程，基站同时该HARQ进程(即所有TB级反馈为NACK的HARQ进程)反馈CBG级ACK/NACK信息。示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4。其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和 CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确。以基站针对所有配置给UE免调度传输的HARQ进程反馈HARQ ACK/NACK信息为例，则指示基站接收到了PUSCH数据的HARQ进程所对应第三bitmap为0100 0011，针对TB级ACK/NACK反馈为100，针对CBG级ACK/NACK反馈为0110 1101，即HARQ ACK/NACK反馈结果为0100 0011 100 0110 1101，共计19比特。图9是本申请实施例提供的另一种携带第三bitmap指示接收进程的TB级ACK/NACK与CBG级ACK/NACK联合反馈示意图。如图9所示，第三bitmap为0100 0011，即HARQ进程2、HARQ进程7和HARQ进程8接收到了PUSCH数据；针对TB级ACK/NACK反馈为100，即HARQ进程2对应的TB解码正确，HARQ进程7和8对应的TB解码错误；针对CBG级ACK/NACK反馈为0110 1101，即对接收到PUSCH数据的三个HARQ进程中TB级反馈为NACK的HARQ进程(包括HARQ进程7和HARQ进程8)反馈CBG级的ACK/NACK信息。
在一实施例中，HARQ ACK/NACK指示包括：第三bitmap，第六HARQ进程集合所对应TB级的ACK/NACK信息，第八HARQ进程集合所对应CBG级的ACK/NACK信息，第五HARQ进程集合包括：所有HARQ进程，或者为UE免调度传输所配置的一个或多个HARQ进程，所有HARQ进程为UE调度和免调度传输所能使用的最大进程数，第六HARQ进程集合为第五HARQ进程集合中基站接收到PUSCH数据所对应的一个或多个HARQ进程，第三bitmap用于指示第六HARQ进程集合中所包含的第五HARQ进程集合中的一个或多个HARQ进程，第八HARQ进程集合为第六HARQ进程集合中前第二预设个数的TB级反馈为NACK的一个或多个HARQ进程。在实施例中，基站针对接收到PUSCH数据的所有HARQ进程，基站基于解码结果反馈HARQ进程的TB级 ACK/NACK，针对前第二预设个数(比如，m个)TB级反馈为NACK的进程，基站同时针对该HARQ进程反馈CBG级ACK/NACK信息。其中，前第二预设个数(前m个)HARQ进程，可以按HARQ进程编号升序/降序排列，取前m个；也可以按发送时间先后对HARQ进程进行排序，取前m个，对此并不进行限定。
在一实施例中，第二预设个数由RRC信息配置。
在一实施例中，第二预设个数为一个默认值。
在一实施例中，第二预设个数由每个TB中的CBG数量进行确定，每个TB中的CBG数量由RRC信令进行配置。在实施例中，m的取值可以通过RRC信令中其它信息隐含指示，比如，可以通过RRC信令中配置每个TB可以拆分的CBG数隐含通知，比如，每个TB可以拆分的CBG数为{0,2,4,6,8}，相应的，m可以取值为{0,8,4,2,2}。其中，对第二预设个数m的解释同上述实施例中对第一预设个数n的解释，可参见上述实施例的描述，在此不再赘述。
在一实施例中，TB级反馈为NACK的HARQ进程数量小于n的情况下，不足部分的CBG级别反馈用NACK填充，即可以用0来填充。
示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4，m的取值为3。其中，UE使用HARQ进程2、5、7和8传输了PUSCH数据，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确。以基站针对所有配置给UE免调度传输的HARQ进程反馈HARQ ACK/NACK信息为例，则指示基站接收到了PUSCH数据的HARQ进程所对应第三bitmap为0100 0011，针 对TB级ACK/NACK反馈为100，针对CBG级ACK/NACK反馈为0110 1101 0000，即HARQ ACK/NACK反馈结果为0100 0011 100 0110 1101 0000，共计23比特。图10是本申请实施例提供的又一种携带第三bitmap指示接收进程的TB级ACK/NACK与CBG级ACK/NACK联合反馈示意图。如图10所示，第三bitmap为0100 0011，即HARQ进程2、HARQ进程7和HARQ进程8接收到了PUSCH数据；针对TB级ACK/NACK反馈为100，即HARQ进程2对应的TB解码正确，HARQ进程7和8对应的TB解码错误；m为3，即对接收到PUSCH数据的三个HARQ进程中TB级反馈为NACK的前3个HARQ进程反馈CBG级的ACK/NACK信息。在实施例中，接收到PUSCH数据的三个HARQ进程中只有两个HARQ进程的TB级反馈为NACK，即TB级反馈为NACK的HARQ进程数量小于m(即小于3)，则不足部分的CBG级反馈用NACK填充，即针对CBG级ACK/NACK反馈为0110 1101 0000。
在一实施例中，基站为UE配置上行免调度资源和免调度传输所使用的HARQ进程范围，UE可以利用上行免调度资源和HARQ进程传输PUSCH数据，基站在免调度资源接收并解码免调度PUSCH数据传输，基站根据PUSCH数据的接收和解码结果为UE反馈DFI信息，其中，DFI包含HARQ ACK/NACK指示，HARQ ACK/NACK指示信息针对HARQ进程解码结果进行反馈指示，该HARQ ACK/NACK指示至少包含以下信息之一：针对HARQ进程的TB级解码反馈指示信息、针对HARQ进程的CBG级解码反馈指示信息。
针对所有配置给UE免调度传输的HARQ进程或所有HARQ进程，基站接收到UE利用HARQ进程传输的PUSCH数据，则根据所接收到的PUSCH数据解码结果，针对进程反馈TB级ACK/NACK信息；基站未收到UE利用HARQ进程传输的PUSCH数据，则针对HARQ进程反馈TB级NACK信息，针对HARQ 进程TB级反馈为NACK的HARQ进程，基站指示需要上报CBG级ACK/NACK信息的HARQ进程，并上报HARQ进程的CBG级ACK/NACK信息。在一实施例中，HARQ ACK/NACK指示包括：第五HARQ进程集合所对应TB级ACK/NACK信息，进程号指示，以及第七HARQ进程集合所对应CBG级的ACK/NACK信息；进程号指示用于指示第七HARQ进程集合中所包含的一个或多个HARQ进程，第五HARQ进程集合包括：所有HARQ进程，或者为UE免调度传输所配置的一个或多个HARQ进程，所述所有HARQ进程为UE调度和免调度传输所能使用的最大进程数，第六HARQ进程集合为第五HARQ进程集合中基站接收到PUSCH数据所对应的一个或多个HARQ进程，第七HARQ进程集合为第六HARQ进程集合中TB级反馈为NACK的一个或多个HARQ进程。
示例性地，基站为UE免调度传输配置的HARQ进程为1-8，每个TB可以拆分的CBG数配置为4，n的取值为3，其中UE使用HARQ进程2、5、7和8传输了PUSCH数据，其中，HARQ进程2对应的TB_1解码正确；HARQ进程5对应的TB_2漏检；HARQ进程7对应的TB_3解码错误，其中TB_3的CBG_1和CBG_4解码错误，CBG_2和CBG_3解码正确；HARQ进程8对应的TB_4解码错误，其中TB_4的CBG_3解码错误，其余CBG解码正确。以基站针对所有配置给UE免调度传输的HARQ进程反馈HARQ ACK/NACK信息为例，针对TB级ACK/NACK反馈为0100 0000，针对TB_3的CBG级ACK/NACK反馈为0111 0110，针对TB_4的CBG级ACK/NACK反馈为1000 1101，也即HARQ ACK/NACK反馈结果为0100 0000 0111 0110 1000 1101，共计24比特。图11是本申请实施例提供的一种TB级ACK/NACK与携带进程号指示的CBG级ACK/NACK联合反馈示意图。如图11所示，针对TB级ACK/NACK反馈为0100 0000，即HARQ进程2对应的TB解码正确，其余HARQ进程对应的TB解码 错误，即可对除HARQ进程2之外的其余7个HARQ进程反馈CBG级ACK/NACK信息。在实施例中，基站指示需要上报CBG级ACK/NACK信息的HARQ进程为HARQ进程7和HARQ进程8，则针对HARQ进程7的CBG级ACK/NACK信息中的进程号指示为0111，而针对HARQ进程8的CBG级ACK/NACK信息中的进程号指示为1000。其中，针对HARQ进程7的CBG级ACK/NACK信息为0110，针对HARQ进程8的CBG级ACK/NACK信息为1101，即针对HARQ进程7所对应TB_3的CBG级ACK/NACK反馈为0111 0110，针对HARQ进程8所对应TB_4的CBG级ACK/NACK反馈为1000 1101。
在一实施例中，基站为UE配置上行免调度资源和免调度传输所使用的HARQ进程范围，UE可以利用上行免调度资源和HARQ进程传输PUSCH数据，基站在免调度资源接收并解码免调度PUSCH数据传输，基站根据PUSCH数据的接收和解码结果为UE反馈DFI信息，其中，DFI为DCI的一种，且DFI的比特域开销与当前DCI格式中的一种DCI的比特域开销大小保持一致。其中，DFI包含HARQ ACK/NACK指示信息，其中，HARQ ACK/NACK指示信息针对HARQ进程解码结果进行反馈指示，该HARQ ACK/NACK指示至少包含以下信息之一：针对HARQ进程的TB级解码反馈指示信息、针对HARQ进程的CBG级解码反馈指示信息。
DFI的比特域开销需要与当前DCI格式中的一种DCI的比特域开销保持一致，DFI比特域开销有最大值限制，即用于反馈CBG级ACK/NACK的比特域开销有最大值限制，在该限制条件下，每个需要反馈CBG级ACK/NACK的CBG占用1比特DFI反馈开销无法得到满足时，可以通过CBG捆绑来实现CBG级ACK/NACK反馈，其中，CBG捆绑是多个CBG解码结果使用1比特ACK/NACK反馈开销反馈，同一个CBG捆绑中的所有CBG解码正确时，针对该CBG捆绑 反馈ACK，其他情况针对CBG捆绑的反馈为NACK。
在一实施例中，在CBG数量大于比特域开销最大值的情况下，采用CBG捆绑反馈CBG级的ACK/NACK信息，CBG数量为反馈CBG级的ACK/NACK信息的TB数量和每个TB所拆分CBG个数的乘积，比特域开销最大值为反馈CBG级的ACK/NACK所对应DFI比特域开销的最大值。在实施例中，CBG级ACK/NACK反馈比特域开销最大值记为CBGlevelHARQsize，需要反馈CBG级ACK/NACK信息的TB数量记为numTB，RRC信令配置每个TB可以拆分的CBG数量记为numCBGPerTB，当

在一实施例中，CBG捆绑包括：采用第一比特反馈前第三预设个数TB所对应CBG级的ACK/NACK信息；采用第二比特反馈前第四预设个数TB所对应CBG级的ACK/NACK信息；第三预设个数和第四预设个数的总和为反馈CBG级的ACK/NACK信息的TB数量，第三预设个数为比特域开销最大值与反馈CBG级的ACK/NACK信息的TB数量之间的取余值，第一比特为比特域开销最大值与反馈CBG级的ACK/NACK信息的TB数量之间比值向上取整的数值；第二比特为开销最大值与反馈CBG级的ACK/NACK信息的TB数量之间比值向下取整的数值。
