Description

反馈信息传输的方法和通信装置
本申请要求于2018年9月7日提交中国专利局、申请号为201811046330.9、申请名称为“反馈信息传输的方法和通信装置”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
本申请涉及通信领域，更为具体的，涉及一种反馈信息传输的方法和装置。
背景技术
在第五代(the fifth generation，5G)移动通信系统中，对于下行的数据传输，例如，对于物理下行共享信道(physical downlink shared channel，PDSCH)的传输，混合自动重传(hybrid automatic repeat request，HARQ)是一种高效的传输机制。一方面，通过重传可以极大提高下行数据传输的可靠性，另一方面，用户设备(user equipment，UE)反馈HARQ的肯定应答(acknowledgement，ACK)/否定应答(negative acknowledgement，NACK)信息，只有反馈NACK时，网络设备才需要进行重传，提高了数据传输效率。
在5G系统中，对于授权频谱上的PDSCH是否正确接收的反馈，其反馈ACK/NACK信息的时域位置(例如时隙)是由网络设备预先指示的。在非授权频谱上，例如5G网络、长期演进(long term evolution，LTE)系统网络等要与其他网络(如无线局域网络(wireless local area networks，WLAN))共享频段。基于公平竞争的原则，网络设备或终端设备在接入使用非授权的频段时，都需要进行监听。只有该频段空闲，没有被其他网络设备或终端设备占用时，该网络设备或终端设备才可以使用这一频段。进一步地，只有在接入这一频段之后，该网络设备或终端设备才能发送信息和数据。
在非授权频谱上，对于网络设备下发的PDSCH，终端设备需要反馈ACK/NACK信息，其反馈ACK/NACK信息的时域位置(以时隙为例说明)不仅取决于网络设备预先调度的时隙位置，更取决于在网络设备预先调度的时隙上终端设备是否可以成功的接入该频段。如果终端设备不能接入(使用)信道(频段)，在预先调度的时隙上就并不能反馈ACK/NACK信息，会造成网络设备不能获知终端设备是否正确接收数据，导致出现网络设备和终端设备之间的通信问题，严重降低了通信效率和用户体验。因此，如何增加ACK/NACK信息在非授权频谱上的反馈机会是一个亟待解决的问题。

首先简单介绍本申请实施例中涉及的主要术语。
授权频谱：由于无线电磁波的资源有限，在国际上对无线电磁波的划分和使用有着严格的规定。授权频谱是无线电磁波频域上的部分频谱。授权频谱受到严格的限制和保护，只允许授权用户及其符合规范的设备接入，而且用户要为此进行付费。目前，公安、铁路、民航、广电、电信等重要的部门均拥有一定的授权频谱，这些部门内设备的通信是运行在其授权频谱上的，尤其是电信行业，我们每天使用的手机就是通过运营商拥有的授权频谱 来通信的，三大运营商都拥有国家无线电管理局授权的专用频段，保障公众移动通信不受干扰。
非授权频谱：非授权频谱是满足一定规范和标准的设备都可以接入和使用的频谱。但必须保证不对其他用户造成干扰。比较典型的是我们经常使用的无线保真(wireless-fidelity，WIFI)、蓝牙都是通过非授权频谱进行传输的。国际通信联盟无线电通信局曾定义过工业、科学、医学(industrial scientific medical，ISM)频段，主要是开放给工业、科学、医学三个机构使用，无需授权许可，当然也需要遵守一定的发射功率，并且不能对其它频段造成干扰即可。
在5G系统中，对于授权频谱上的PDSCH是否正确接收的反馈，其反馈ACK/NACK信息的时域位置(例如时隙)是由网络设备预先指示的。在非授权频谱上，基于公平竞争的原则，网络设备或终端设备在接入使用非授权的频段时，都需要进行监听，例如进行先听后说(listen before talk，LBT)或者空闲信道评估(clear channel assessment，CCA)。只有该频段空闲，没有被其他网络设备或终端设备占用时，该网络设备或终端设备才可以使用这一频段(信道)。进一步地，只有在接入这一频段(信道)之后，网络设备或终端设备才能发送信息和数据。
在非授权频谱上，对于网络设备发送的PDSCH，终端设备需要反馈ACK/NACK信息，其反馈ACK/NACK信息的时域位置不仅取决于网络设备预先调度的时域位置，更取决于在网络设备预先调度的时域位置之前终端设备是否可以成功的接入该频段。如果终端设备不能接入频段(信道)，在预先调度的时域位置上就并不能反馈ACK/NACK信息，会造成网络设备不能获知终端设备是否正确接收数据，导致出现网络设备和终端设备之间的通信问题，严重降低了通信效率和用户体验。因此，如何增加ACK/NACK信息在非授权频谱上的反馈机会是一个亟待解决的问题。
基于上述问题，本申请提供了一种反馈信息传输的方法，可以增加反馈信息在非授权频谱上的反馈机会，很大程度上降低终端设备出现没有资源发送反馈信息的情况的发生，避免网络设备和终端设备之间因为反馈信息不能传输出现的通信问题，提高通信效率和用户体验。
下面结合图2详细说明本申请提供的反馈信息传输的方法，图2是本申请一个实施例的反馈信息传输的方法200的示意性交互图，该方法200可以应用在图1所示的场景中，当然也可以应用在其他通信场景中，本申请实施例在此不作限制。
应理解，在本申请实施例中，以终端设备和网络设备作为执行方法200的执行主体为例，对方法200进行说明。作为示例而非限定，执行方法200的执行主体也可以是应用于终端设备的芯片和应用于基站的芯片。
如图2所示，图2中示出的方法200可以包括步骤210至步骤250。下面结合图2详细说明方法200中的各个步骤。
S210，网络设备向终端设备发送第一下行消息对应的第一反馈信息的时频资源配置信息。相应的，终端设备接收该第一反馈信息的时频资源配置信息。
S220，网络设备向终端设备发送该第一下行消息，相应的，终端设备接收该第一下行消息。
S230，终端设备接入信道，第一时间窗内的上行传输资源在该信道上。
S240，在该终端设备接入该信道(能够使用信道)后，确定该信道上用于传输第一上行信息的第一上行传输资源，第一上行传输资源为第一时间窗所包括的至少一个上行传输资源中的一个，该第一时间窗包括至少一个上行传输资源，至少一个上行传输资源中的每个上行传输资源用于传输上行信息。
S250，该终端设备在该第一上行传输资源上向该网络设备发送第一反馈信息和该第一上行信息的联合信息，该第一反馈信息响应于该第一下行消息。相应的，网络设备在该第一上行传输资源上接收该联合信息。
本申请提供的反馈信息传输的方法，终端设备不仅可以在预先配置的第一反馈信息的时频资源上发送第一反馈信息。还可以在第一时间窗内的一个或者多个上行传输资源中的第一上行传输资源上发送第一反馈信息。终端可以在第一上行传输资源上发送该第一反馈信息和该第一上行信息的联合信息。可以增加第一反馈信息在非授权频谱上的发送机会，很大程度上降低终端设备出现没有资源发送反馈信息的情况的发生。避免网络设备和终端设备之间因为反馈信息不能传输出现的通信问题，提高通信效率和用户体验。
具体而言，在S210中，在非授权频谱上，网络设备在有数据需要向终端设备发送时，也需要进行接入信道的过程。例如，通过CCA或者LBT过程，在监听到信道空闲时，才可以(能够)使用该信道。可以(能够)使用该信道可以理解为：终端设备进行信道监听发现没有其他网络或终端设备使用该信道，该信道处于空闲状态，那么该终端设备可以使用该信道。在本申请实例中，接入信道和能够(可以)使用信道的含义相同，两者可以替换。
在终端设备接入信道后，才可以向终端设备发送数据或者信令等。网络设备在接入信道后，会向终端设备第一下行消息对应的第一反馈信息的时频资源配置信息。即网络设备向终端设备指示第一下行消息的反馈信息的时频资源位置(也可以称为预配置的反馈位置)。第一下行消息可以包括下发给终端设备的数据和/或控制信令。例如，第一下行消息可以是下发给设备的PDSCH，则第一反馈信息为PDSCH的ACK或者NACK信息。第一下行消息也可以包括下发给终端设备的控制信令，例如，可以是下行控制信息(downlink control information，DCI)。第一下行消息是触发终端设备进行信道状态测量的控制信令，则第一反馈信息为信道状态信息(channel state information，CSI)。或者第一下行消息还可以是触发终端设备进行其他信息反馈的控制信令。该第一反馈信息为响应于第一下行消息的反馈信息。该第一反馈信息在信道上承载。应理解，网络设备和终端设备接入的信道可以不同。例如，可以是跨载波的调度，网络设备发送的第一下行消息(例如可以是下行数据)在载波(component carrier，CC)1上，而第一反馈信息(例如为ACK/NACK信息)在CC2上向网络设备发送。也可以是跨不同子带(sub-band)的调度，或者可以是跨不同的部分带宽(bandwidth part，BWP)的调度。
例如，该第一下行消息为第一PDSCH时，第一下行消息对应的第一反馈信息为与第一PDSCH对应的第一PDSCH是否正确译码的第一ACK或者NACK信息。例如，第一ACK表示第一PDSCH正确译码，第一NACK表示第一PDSCH非正确译码。网络设备会将第一ACK或者NACK信息的时频资源配置(预配置的反馈位置)通知给终端设备。具体的，可以通过高层配置信息，例如PDCCH上的下行控制信息(downlink control information，DCI)指示第一ACK或者NACK信息的时频资源配置。或者通过无线资源 控制(radio resource control，RRC)信令通知终端设备第一ACK或者NACK信息的时频资源配置。
又例如，该第一下行消息为触发终端进行信道测量的控制信令时，第一下行消息对应的第一反馈信息为信道的CSI。网络设备会将信道的CSI的时频资源配置(预配置的反馈位置)通知给终端设备。以便于终端设备在预配置的CSI的时频资源上向网络设备反馈该信道的CSI。
在S220中，网络设备向终端设备发送上述的第一下行消息。相应的，终端设备接收该第一下行消息。应理解，第一下行消息可以为一个或者多个下行数据，每个下行数据可以多次重复发送。当第一下行消息为多个下行数据时，第一反馈信息可以是针对于多个下行数据中的全部或者部分数据反馈信息。例如，如果第一下行消息为第一PDSCH，第一PDSCH可以是多个PDSCH。也可以是一个PDSCH。也可以是一个PDSCH的多次重复。当第一PDSCH是多个PDSCH时，第一反馈信息为该多个PDSCH中的部分或者全部PDSCH的是否正确译码的反馈信息。
在S230中，在终端设备接收到该第一下行消息和第一下行消息对应的第一反馈信息的时频资源配置信息后，确定需要在第一反馈信息所在的信道上向网络设备发送该第一反馈信息。因此，终端设备需要进行接入信道的过程。例如，通过CCA或者LBT，在监听到信道空闲且已经生成第一反馈信息时，才可以接入信道。在接入信道后，才可以向网络设备发送该第一反馈信息。应理解，在非授权频谱中，终端设备进行信道监听的过程可以是一直存在的。当终端设备有数据或者信息需要发送并且信道处于空闲时，终端设备在可以接入信道并进一步的发送需要发送的数据或者信息。
由于终端设备接入信道的过程需要一定的时间，因此，在时域上可以将终端设备接入信道的过程(信道监听并且接入信道的过程)所用的时间看成一个时间段。这一时间段可以看成是一个竞争窗口。如果终端设备接入信道的过程在预配置的第一反馈信息的时域位置开始前完成。例如：当第一反馈信息为第一ACK或者NACK信息时，假设预配置的第一ACK或者NACK信息的时域位置为信道上的第3个时隙(slot)上的所有符号(symbol)，终端设备接入信道的过程在第3个时隙前已经完成。或者，假设预配置的第一ACK或者NACK信息的时域位置为信道上的第3个时隙(slot)的第5个符号至第7个符号，终端设备接入信道的过程在第3个时隙的第五个符号前已经完成。则终端设备可以在预配置的第一ACK或者NACK信息的时频位置上向网络设备发送该第一ACK或者NACK信息。
如果终端设备接入信道的过程是在预配置的第一反馈信息的时域位置开始后完成。例如：当第一反馈信息为第一ACK或者NACK信息时，假设预配置的第一ACK或者NACK信息的时域位置为信道上的第3个时隙(slot)的所有符号(symbol)，终端设备接入信道过程的结束时刻晚于在第3个时隙的开始时刻。或者，假设第一ACK或者NACK信息的时域位置为信道的第3个时隙(slot)中的第5个至第7个符号，终端设备接入信道的过程在第3个时隙的第5个符号开始后才完成。由于已经错过了预配置的第一ACK或者NACK信息的时域资源。终端设备便不能在预配置的第一ACK或者NACK信息的时域资源发送第一ACK或者NACK信息。这样导致终端设备不能反馈第一ACK或者NACK信息。
因此，在步骤S240中，在该终端设备接入该信道后，该终端设备在该信道上的第一 时间窗内的一个或者多个上行传输资源中确定第一上行传输资源，该第一上行传输资源用于传输第一上行信息。第一时间窗内的上行传输资源在该信道上。该第一时间窗包括一个或者上行传输资源，每个上行传输资源用于传输上行信息。第一时间窗与该第一反馈信息对应，即第一时间窗是为该第一反馈信息配置的。终端设备可以在该第一时间窗包括的上行传输资源发送该第一反馈信息。该终端设备接入该信道的结束时刻可以在该第一时间窗包括的时域范围内的任何一个时域位置上。在第一时间窗包括多个上行传输资源时，终端设备接入该信道的结束时刻可以早于第一时间窗包括的任意一个上行传输资源的开始时刻，或者晚于第一时间窗包括的任意一个上行传输资源的开始时刻。
第一时间窗的信息可以是终端设备和网络设备事先协商好并且双方都预存的，即第一时间窗的时频位置等信息可以是预先配置好的。该第一时间窗包括一个或者多个上行传输资源，每个上行传输资源用于传输上行信息。第一时间窗可以是一个时域范围(时间段)，即第一时间窗可以是一个时间长度或者时间范围。在这个时域范围内包括多个上行传输资源。每个上行传输资源的时频信息都是网络设备通过指示信息或者配置信息事先通知给终端设备的，并且每个上行传输资源专用于传输一种上行信息。第一时间窗包括一个或者多个上行传输资源在该信道上。在终端设备接入该信道后，在该一个或者多个上行传输资源中确定第一上行传输资源。应理解，当第一时间窗内只有一个上行传输资源时，这个上行传输资源就是该第一上行传输资源。由于终端设备接入信道的过程需要一定的时间，因此，在时域上可以将终端设备接入信道的过程所用的时间看成一个时间段。第一上行传输资源的时域位置在终端设备接入该信道所用的时间段后。即终端设备接入信道过程的结束时刻要早于该第一上行传输资源的开始时刻。该第一上行传输资源用于传输第一上行信息。即在预先的配置中，第一上行传输资源是专用于传输第一上行信息的。
应理解，第一时间窗包括的一个或多个上行传输资源可以不包括上述的预配置的用于传输第一反馈信息的上行传输资源。当然，也可以包括上述的预配置的用于传输第一反馈信息的上行传输资源。终端设备可以利用该第一时间窗内包括的一个或多个上行传输资源来传输该第一反馈信息。该第一时间窗也可以不包括的上行传输资源，第一时间窗仅是一个时间段或者时间范围，第一时间窗内不包括一个或者多个预配置的上行传输资源。在这种情况下，网络设备可以通过DCI为终端设备调度该第一时间窗内的某些资源用来传输该第一反馈信息，即调度该第一时间窗内的某些资源作为上行传输资源。
还应理解，在第一时间窗内有多个上行传输资源时，多个上行传输资源的频域可以相同，也可以不同。多个上行传输资源可以位于不同的子载波、子带、部分带宽，即多个上行传输资源的频域位置不同。当然，多个上行传输资源也可以位于相同的子载波、子带以及部分带宽上，即多个上行传输资源的频域位置相同。
还应理解，第一时间窗可以是从网络设备调度响应于第一下行消息对应的第一反馈信息的时域资源的最后一个符号之后的第一个时间单元开始，该时间单元可以是符号或者时隙。即第一时间窗的单位可以是符号或者时隙等。经过一个预设的时间阈值后结束，从开始到结束的这个时间段的长度为该第一时间窗的时间长度。这个时间阈值的大小可以是从网络设备调度该第一反馈信息的时间单元开始，到网络设备认为终端设备发送的第一反馈信息为非连续发送(discontinuous transmission，DTX)的状态的时刻结束。例如，当第一下行消息为第一PDSCH时，第一时间窗可以是从网络设备调度反馈第一PDSCH的 ACK/NACK的时域资源(例如时隙n上的第7个至第13个符号)的最后一个符号(第13个符号)之后的第一个符号开始，在小于或者等于一个时间阈值后结束(例如时间阈值为T个时隙)的这个时间段，则第一时间窗的时域位置为从时隙n+1的第1个符号开始开始，经过时间长度为小于或者等于T个时隙的时域位置结束。这个时间阈值是从网络设备调度反馈第一PDSCH的ACK/NACK的时刻开始，到网络设备认为的终端设备所发ACK/NACK为DTX的状态的时刻结束，即网络认为没有收到调度第一PDSCH的PDCCH。
还应理解，第一时间窗的时间长度可以是网络设备通过高层信令配置的，也可以是协议预定义的。预定义的时间窗的大小可以是固定的，也可以和终端设备接入信道所用的时间的长短相关。例如，终端设备接入信道所用的时间越长，第一时间窗的时间长度也越长。
还应理解，第一时间窗可以位于一个信道占用时间(channel occupancy time，COT)之内，即第一时间窗的时间长度小于一个COT。当然，第一时间窗也可以包括多个COT。本申请实施例在此不作限制。
还应理解，在第一时间窗内有多个上行传输资源情况下，如果多个上行传输资源在时域上是连续的(例如，相邻的两个上行传输资源的时域间隔小于或者等于16微秒)，且在一个信道(频段)上，那么对于位于一个COT内的相邻的两个上行传输资源，如果终端设备在第一个上行传输资源上接入信道，在第二个上行传输资源就可以不用进行LBT或者CCA，即在第二个上行传输资源上不用在进行接入信道的过程，可以直接在第二个上行资源上发送信息或者数据。但是如果第一时间窗内相邻的两个上行传输资源在时域资源是非连续的(例如，相邻的两个上行传输资源的时域间隔大于16微秒)或者，在频域上是不同的，终端设备需要在这两个上行传输资源上分别进行LBT或者CCA，即需要分别进行接入信道的过程(进行信道监听的过程)。
在步骤S250中，终端设备在该第一上行传输资源上向该网络设备发送该第一反馈信息和该第一上行信息的联合信息。具体的，这里的联合信息可以是下述的几种形式中的任意一种。
例如，终端设备将第一反馈信息和该第一上行传输资源上由网络设备预配置传输的第一上行信息共同生成一个码本，然后将这个码本进行编码得到该联合信息。两个信息共同生成一个码本可以理解为：例如，两个PDSCH可以一起反馈ACK/NACK，即同时反馈两个ACK/NACK信息，那么此时两个ACK/NACK信息会一起产生ACK/NACK的比特，称之为一个码本。或者，终端设备将第一反馈信息和该第一上行传输资源原来传输的第一上行信息分别各自独立的生成码本，然后将两个码本进行独立或者联合编码后得到该联合信息。或者，终端设备将第一反馈信息和该第一上行信息进行某种运算得到该联合信息，可选的，可以是进行逻辑与运算得到该联合信息。或者，该联合信息可以是第一反馈信息和第一上行信息中的一个，例如，该联合信息为第一反馈信息和第一上行信息中优先级较高的信息。终端设备还可以抢占第一时间窗内的某一个上行传输资源来发送该第一反馈信息，而在该上行传输资源上不发送预配置的上行信息。即终端设备可以使用为其他上行信息配置的专用上行传输资源来传输该第一反馈信息。或者，还可以利用第一反馈信息对该第一上行信息进行加扰的方式得到该联合信息，或者可以利用第一上行信息对第一反馈信息进行加扰的方式得到该联合信息。例如，通过两者的加扰的方式生成的新的反馈信息为该联合信息等。本申请实施例对联合信息的具体生成过程不作限制。
例如，假设第一反馈信息为第一ACK或NACK信息，第一上行信息为PUSCH时，第一ACK或NACK信息可以通过打孔(puncture)或者速率匹配(rate matching)的方式，占用为PUSCH中数据的上行传输资源中的一部分资源来传输。本申请实施例在此不作限制。
又例如，假设第一反馈信息为第一ACK或NACK信息，第一上行信息为CSI时，可以将第一ACK或NACK信息和CSI联合进行编码，得到该联合信息。或者，该联合信息可以是第一ACK或NACK信息或者是CSI。例如，当第一ACK或NACK信息优先级较高，而且为CSI配置的上行传输资源比较少或最大码率较低，只能传输第一ACK或NACK信息或者CSI时，终端设备可以利用配置的上行传输资源传输第一ACK或NACK信息，而不传输CSI。
如果终端设备在第一时间窗的时域范围内都没有接入该信道，终端设备在第一时间窗内的上行传输资源上便不能向网络设备发送该第一反馈信息。在这种情况下，若网络设备为第一反馈信息配置多个时间窗，在该第一时间窗结束后，终端设备可以继续利用上述的方案，在预配置的另一个时间窗内进行第一反馈信息的联合发送。本申请实施例在此不作限制。
如果网络设备在第一时间窗结束后还没有收到该第一反馈信息，便认为第一反馈信息为非连续发送(discontinuous transmission，DTX)状态。网络设备认为该第一下行消息没有成功的向终端设备发送。这种情况下，网络设备可以重新向终端设备发送该第一下行消息。
本申请提供的反馈信息传输的方法，网络设备通过向终端设备发送第一时间窗的时频配置，而第一时间窗是包括一个或者多个由网络设备为其他上行信息配置的上行传输资源的。终端设备可以在第一时间窗包括的上行传输资源中的第一上行资源上发送第一信息。即在第一上行传输资源上发送第一反馈信息和第一上行传输资源预配置的第一上行信息的联合信息。可以很大程度上增加第一反馈信息在非授权频谱上的反馈机会，降低终端设备出现没有资源发送反馈信息的情况的发生，避免网络设备和终端设备之间因为反馈信息不能传输出现的通信问题。并且，网络设备只需要在第一时间窗的时间范围的上行传输资源去检测该第一反馈信息，不用在其他上行传输资源上检测该第一反馈信息，可以降低网络设备需要盲检的范围，降低网络设备为更多潜在发送机会配置更多资源从而造成的资源消耗。网络设备不用长时间的等待该第一反馈信息，缩短了网络设备等待该第一反馈信息的时间，降低了反馈第一反馈信息的延迟。并且，网络设备不需要额外的为该第一反馈信息配置或者调度上行传输资源，可以节约上行传输资源，使得网络设备可以更高效的实现资源的调度，保证了其它上行信息可以更加可靠的进行传输，提高了资源的利用率。
下面将结合具体的例子来说明本申请提供的反馈信息传输的方法。
如图3所示，图3是本申请一个实施例的时间窗的示意图。在图3中，以第一下行消息为第一PDSCH、时间窗的时域单位为时隙，该第一反馈信息为第一PDSCH的第一ACK或NACK信息为例进行说明。图3中，终端设备监听接入的信道与发送上行信息的信道是同一信道。即终端设备进行LBT或者CCA的过程和第一时间窗所在的频域相同。终端设备接收到该第一PDSCH。因此终端需要反馈与第一PDSCH对应的ACK或NACK信息。
如图3所示，网络设备预配置的第一PDSCH对应的第一ACK或NACK信息的时域 位置为时隙n-1上的部分符号。第一时间窗的时域范围为时隙n至时隙n+3，即第一时间窗在时域上包括4个时隙。第一时间窗内包括3个上行传输资源，分别是时隙n上的用于传输第三PDSCH对应的第三ACK或NACK信息。第三PDSCH与上述的第一PDSCH不同，第三ACK或NACK信息也与上述的第一ACK或NACK信息不同。时隙n+2上的用于传输CSI的上行传输资源，以及时隙n+3上的用于传输PUSCH的上行传输资源。终端设备在时隙n-1上(或者时隙n-1之前)未接入信道，即终端设备接入信道的结束时刻晚于时隙n-1上的上行传输资源(第一ACK或NACK信息的资源)的起始时刻。终端设备不能在时隙n-1上的预配置的第一PDSCH对应的第一ACK或NACK信息的时频资源上发送第一ACK或NACK信息。
如图3所示，如果终端设备在时隙n上(或者时隙n之前)未能接入信道，则终端设备不能在时隙n上发送第一ACK或NACK信息。在时隙n上(或者时隙n之前)未能接入信道可以理解为：终端设备接入信道的结束时刻(T3时刻)晚于时隙n上的上行传输资源的起始时刻(T1时刻)，或者，信道被其他终端设备所占用，不能接入该信道。例如，当时隙n上的上行传输资源占了时隙n上第5个符号至第9个符号时，终端设备接入信道的结束符号晚于时隙n上的第5个符号。如果终端设备在时隙n+2上(或者时隙n+2之前)接入信道，则终端设备可以在时隙n+2或者时隙n+3上的上行传输资源上发送该第一ACK或NACK信息。在时隙n+2上(或者时隙n+2之前)接入信道可以理解为：终端设备接入信道的结束时刻(T2时刻)早于时隙n+2上的上行传输资源的起始时刻(T4时刻)。例如，当时隙n+2上的上行传输资源占了时隙n+2上第5个符号至第9个符号时，终端设备接入信道的结束符号早于时隙n+2上的第5个符号。如果终端设备在时隙n+2上(或者时隙n+2之前)接入信道，终端设备可以在时隙n+2上发送第一ACK或NACK信息和CSI的联合信息。
应理解，如果时隙n+2上的用于传输CSI的上行传输资源的结束时刻与时隙n+3上的用于传输PUSCH的上行传输资源的开始时刻的时间间隔小于一定的阈值(例如16微秒)，即传输CSI的上行传输资源和传输PUSCH的上行传输资源在时域上是连续的，并且两个的频域相同，因此，对于时隙n+3上传输PUSCH的上行传输资源，终端设备不需要再进行新的接入信道过程。也可以直接选择在时隙n+3上发送第一ACK或NACK信息和PUSCH的联合信息。如果时隙n+2上的用于传输CSI的上行传输资源的结束时刻与时隙n+3上的用于传输PUSCH的上行传输资源的开始时刻的时间间隔大于一定的阈值(例如16微秒)，即传输CSI的上行传输资源和传输PUSCH的上行传输资源在时域上是不连续的，则还需要在时隙n+3上进行接入信道的过程。图3所示的为传输CSI的上行传输资源和传输PUSCH的上行传输资源在时域上是不连续的情况。如果终端设备在时隙n+3上(或者时隙n+3之前)接入信道。则终端设备可以在时隙n+3上的上行传输资源上发送该第一ACK或NACK信息。如果终端设备在时隙n+3之后在接入信道(接入信道的结束时刻在PUSCH的上行传输资源开始时刻之后)。终端设备在第一时间窗包括的多个上行传输资源上便不能向网络设备发送该第一ACK或NACK信息。在这种情况下，网络设备在第一时间窗结束后还没有收到该第一ACK或NACK信息，便认为第一ACK或NACK信息为DTX状态。在后续的上行传输资源上便不在盲检该第一ACK或NACK信息。
应理解，图3只是示例性的，不应该对本申请的实施例造成限制。例如，上述的第一 时间窗可以包括预配置的用于传输第一ACK或NACK信息上行传输资源，该第一时间窗还可以包括更多的时隙，该第一时间窗可以是更长的时间长度，该第一时间窗还可以包括的上行传输资源还可以是用于传输其他上行信息的上行传输资源、第一时间窗内的一个或者多个上行传输资源可以分别占据各自时隙上的全部符号、第一时间窗包括的多个上行传输资源的频域位置还可以是不同的。例如，如图4所示，图4是本申请一个实施例的时间窗的示意图。如图4所示为第一时间窗包括的多个上行传输资源的频域位置不同的情况。对于图4所示的情况，终端设备需要在每个时隙上(上行传输资源上)进行接入新信道的过程。本申请实施例在此不作限制。又例如，如图5所示，图5是本申请一个实施例的时间窗的示意图。如图5所示为第一时间窗的单位为符号的情况，即第一时间窗为符号级的时间窗。例如，第一时间窗是从时隙n-1上的某些符号开始的。本申请实施例在此不作限制。
可选的，作为一个实施例，图6是本申请另一个实施例的反馈信息传输的方法的示意性交互图。如图6所示，该方法200还包括：
S221，该网络设备向终端设备发送第一配置信息，该第一配置信息包括该第一时间窗的信息。相应的，该终端设备接收该第一配置信息。
具体而言，第一时间窗的信息可以是预定义的，即终端设备和网络设备预先协商并且预存的。第一时间窗的信息也可以是网络设备通知给终端设备的，即通过向终端设备发送第一配置信息的方式，该第一配置信息包括该第一时间窗的信息。终端设备在收到该第一配置信息，并且在接入信道后，便可以在利用第一时间窗包括的上行传输资源发送该第一反馈信息。第一时间窗的信息可以包括上述的第一时间窗的起始位置和结束位置等，也可以包括第一时间窗的绝对时间长度，还可包括第一时间窗包括多个上行传输资源的信息、例如，多个上行传输资源的时频位置、大小、多个上行传输资源传输的上行信息的优先级等。该第一配置可以是通过RRC信令承载、或者也可以是通过其他控制信令承载。本申请实施例在此不作限制。
可选的，作为一个实施例，在该上行传输资源为多个的情况下，该第一上行传输资源为该第一时间窗内、在该终端设备接入该信道的结束时刻后第一个上行传输资源；
或者，该第一上行传输资源为该第一时间窗内、多个上行传输资源传输的上行信息中码率最低的上行信息所在的上行传输资源，其中，多个上行传输资源中每个上行传输资源用于传输上行信息；
或者，该第一上行传输资源为该第一时间窗内、该多个上行传输资源中占用资源单元最多的上行传输资源；
或者，该第一上行传输资源为该第一时间窗内、该多个上行传输资源传输的多个上行信息中优先级最高或者最低的上行信息所在的上行传输资源。
具体而言，在本申请实施例中，由于终端设备接入信道的过程需要一定的时间，因此，在时域上可以将终端设备接入信道的过程所用的时间看成一个时间段。而且第一时间窗内包括多个上行传输资源，因此，在终端设备接入该信道的结束时刻后，第一时间窗可能还剩余一个或者多个上行传输资源。终端设备接入该信道后可以理解为终端设备接入该信道过程的结束时刻后(时域位置后)。
例如，以图3所示的为例进行说明。如果终端设备在时隙n+2上(或者时隙n+2之前) 接入信道，则在终端设备接入该信道的时刻(T2时刻)后，第一时间窗还剩下2个上行传输资源。如果终端设备在时隙n+3上(或者时隙n+3之前)接入信道，则在终端设备接入该信道的结束时刻后，第一时间窗还剩下1个上行传输资源。如果终端设备在时隙n上(或者时隙n之前)接入信道，则在终端设备接入该信道的结束时刻(T1时刻)后，第一时间窗还剩下3个上行传输资源。因此，终端设备可以在该剩余多个上行传输资源中确定该第一上行传输资源。具体的，可以有以下几种确定该第一上行传输资源的方式：
第一种方式：该第一上行传输资源为该第一时间窗内、在该终端设备接入该信道的结束时刻后第一个上行传输资源。
第二种方式：该第一上行传输资源为该第一时间窗内、多个上行传输资源传输的上行信息中码率最低的上行信息所在的上行传输资源。
第三种方式：该第一上行传输资源为该第一时间窗内、该多个上行传输资源中占用资源单元最多的上行传输资源。
第四种方式：该第一上行传输资源为该第一时间窗内、该多个上行传输资源传输的多个上行信息中优先级最高或者最低的上行信息所在的上行传输资源。
对于上述的第一种方式，在终端设备接入该信道后，第一时间窗内可能还剩余一个或者多个上行传输资源。当第一时间窗内还剩余或者多个上行传输资源时，该第一上行传输资源为剩余的多个上行传输资源中码率最低的上行传输资源。例如，以图7所示的为例进行说明，图7是本申请一个实施例的时间窗的示意图。在图7中，以第一下行消息为第一PDSCH、时间窗的时域单位为时隙，该第一反馈信息为第一PDSCH的第一ACK或NACK信息，网络设备预配置的第一PDSCH对应的第一ACK或NACK信息的时域位置为时隙n-1上的部分符号。第一时间窗的时域范围为时隙n至时隙n+3为例进行说明。
如果终端设备在时隙n上(或者时隙n之前)接入信道，则在终端设备接入该信道的结束时刻(T5时刻)后，第一时间窗还剩下3个上行传输资源。3个上行传输资源的开始时刻依次为T1时刻、T4时刻、T6时刻。3个上行传输资源的开始时刻按照时域上距离终端设备接入信道的结束时刻(T5时刻)的时间间隔从小到大的顺序依次为：传输第三ACK或NACK信息上行传输资源、传输CSI的上行传输资源，以及传输PUSCH的上行传输资源。第三ACK或NACK信息与第三PDSCH对应，第三PDSCH与上述的第一PDSCH不同，第三ACK或NACK信息也与上述的第一ACK或NACK信息不同。如果终端设备在时隙n+2上(或者时隙n+2之前)接入信道，接入信道的结束时刻为T2时刻，第一时间窗内包括的、在该终端设备接入该信道后第一个上行传输资源为传输CSI上行传输资源。即第一上行传输资源为传输CSI上行传输资源。可以降低传输时延，提高传输的可靠性。
对于上述的第二种方式，以图7所示的为例进行说明，终端设备在时隙n上(或者时隙n之前)接入信道，则在终端设备接入该信道的时刻(T5时刻)后，第一时间窗还剩下3个上行传输资源。3个上行传输资源按照时域上距离终端设备接入信道的时刻(T5时刻)的时间间隔从小到大的顺序依次为：传输第三ACK或NACK信息上行传输资源、传输CSI的上行传输资源，以及传输PUSCH的上行传输资源。假设这3个上行传输资源传输的上行信息中PUSCH的码率最低，则第一上行传输资源为传输PUSCH的上行传输资源。在传输码率最低的上行信息的上行传输资源传输该联合信息，可以保证该联合信息传输的可靠性，即保证该第一反馈信息传输的可靠性。应理解，对于图6所示的情况，终端 设备还需要分别在时隙n+2上和时隙n+3上进行接入信道的过程(即信道监听的过程)。
对于上述的第三种方式，以图7所示的为例进行说明，终端设备在时隙n上(或者时隙n之前)接入信道，则在终端设备接入该信道的结束时刻(T5时刻)后，第一时间窗还剩下3个上行传输资源。3个上行传输资源的开始时刻按照时域上距离终端设备接入信道的结束时刻(T5时刻)的时间间隔从小到大的顺序依次为：传输第三ACK或NACK信息上行传输资源、传输CSI的上行传输资源，以及传输PUSCH的上行传输资源。假设这3个上行传输资源中占用资源单元最多的上行传输资源为传输PUSCH的上行传输资源。即第一上行传输资源为传输PUSCH的上行传输资源。在占用资源单元最多的上行传输资源传输该联合信息，可以保证该联合信息传输的可靠性，即保证该第一反馈信息传输的可靠性。应理解，这里的资源单元可以是资源单元(resource element，RE)或者是资源块(resource block，RB)等，本申请在此不作限制。
对于上述的第四种方式，以图7所示的为例进行说明，终端设备在时隙n上(或者时隙n之前)接入信道，则在终端设备接入该信道的结束时刻(T5时刻)后，第一时间窗还剩下3个上行传输资源。按照时域上距离终端设备接入信道的结束时刻(T5时刻)的时间间隔从小到大的顺序依次为：传输第三ACK或NACK信息上行传输资源、传输CSI的上行传输资源，以及传输PUSCH的上行传输资源。假设这3个上行传输资源传输的上行信息中优先级最高为第三ACK或NACK信息，则在传输第三ACK或NACK信息上传输该第一反馈信息。可以降低该联合信息的传输时延，提高第一反馈信息的传输效率。如果终端设备在时隙n+2上(或者时隙n+2之前)接入信道，接入信道的结束时刻为T2时刻。第一时间窗包括的、在该终端设备接入该信道后的上行传输资源为传输CSI上行传输资源和传输PUSCH的上行传输资源。这两个相比较CSI的优先级比较高，即第一上行传输资源为传输CSI上行传输资源。如果将该第一时间窗包括的、在接入该信道后该多个上行传输资源传输的多个上行信息中优先级最低的上行信息所在的上行传输资源确定为该第一上行传输资源，可以保证该第一时间窗内优先级较高的上行信息的传输，提高优先级较高的上行信息的传输保障，提高通信效率。应理解，对于图6所示的情况，终端设备还需要分别在时隙n+2上和时隙n+3上进行接入信道的过程。
应理解，除了利用上述的几种方式在第一时间窗包括的多个上行传输资源中确定该第一上行传输资源外，还可以利用其他的方式确定该第一上行传输资源。或者，还可以利用上述的几种方式的任意组合、并且每种方式可以占不同的比重来确定该第一上行传输资源等。本申请实施例在此不作限制。
可选的，作为一个实施例，图8是本申请另一个实施例的反馈信息传输的方法的示意性交互图。如图8所示，该方法200还包括：
S211，网络设备向终端设备发送第二下行消息对应的第二反馈信息的时频资源配置信息。相应的，终端设备接收该第二反馈信息的时频资源配置信息。
S222，网络设备向终端设备发送的第二下行消息。相应的，终端设备接收该第二下行消息。
S241，该终端设备根据该第一反馈信息和第二反馈信息确定第三反馈信息，该第二反馈信息响应于该第二下行消息；
在S250中，该终端设备在该第一上行传输资源上向该网络设备发送第一反馈信息和 该第一上行信息的联合信息，包括：
S251该终端设备在该第一上行传输资源上向该网络设备发送该第三反馈信息和该第一上行信息的联合信息。
具体而言。在步骤S211和S222中，如果终端设备除了收到第一下行消息和第一反馈信息的时域资源配置之外，还收到了第二下行消息和第二反馈信息的时域资源配置，该第二反馈信息响应于该第二下行消息。类似的，如果终端设备接入信道的过程(接入信道的时刻)是在预先配置的第二反馈信息的时域位置开始后完成的，网络设备也会为该第二反馈信息的反馈配置第二时间窗。第二时间窗可以是一个时域范围(时间段或者时间长度)，在这个时域范围内包括一个或多个上行传输资源。每个上行传输资源都是预先配置给终端设备，并且专用于传输一种上行信息。一个或多个上行传输资源可以不包括上述的预配置的用于传输第二反馈信息的上行传输资源。当然，也可以包括上述的预配置的用于传输第二反馈信息的上行传输资源。终端设备可以利用该第二时间窗内包括的上行传输资源来传输该第二反馈信息。第二下行消息可以包括下发给终端设备的数据和/或控制信令。例如，第二下行消息可以是下发给设备的PDSCH，则第二反馈信息为PDSCH的ACK或者NACK信息。第二下行消息也可以包括下发给终端设备的控制信令，例如，可以是PDCCH。当第二下行消息是控制信令时，可以是触发终端设备进行信道测量的控制信令，则第二反馈信息为CSI。或者还可以是触发终端设备进行其他信息反馈的控制信令。该第二反馈信息为响应于第二下行消息的反馈信息。该第二反馈信息在信道上承载。第二时间窗的信息可以是预定义的，即终端设备和网络设备预先协商并且预存的。第二时间窗的信息也可以是网络设备通知给终端设备的。终端设备也可以在第二时间窗包括的上行传输资源中确定第二上行传输资源，第二上行传输资源用于发送第二反馈信息和第二上行信息的联合信息。第二上行传输资源被预配置为专用于发送该第二上行信息。应理解，第二时间窗与该第一时间窗类似，相关描述可以参考上述对第一时间窗的描述，为了简洁，这里不再赘述。
在该第一时间窗和第二时间窗时域上有重叠的情况下，终端设备需要确定在该第一上行传输资源上发送的信息到底是哪一个。即在步骤S241中，终端设备根据该第一反馈信息和第二反馈信息确定第三反馈信息。第三反馈信息可以是该第一反馈信息和第二反馈中的一个，也可以是该第一反馈信息和第二反馈信息，也可以是第一反馈信息和第二反馈信息逻辑与运算之后得到信息。
在步骤S251中，终端设备在该第一上行传输资源上发送该第三反馈信息和该第一上行信息的联合信息。相应的网络设备在第一上行传输资源上接收该联合信息。
应理解，在图8中，虚线所示的步骤为可选的步骤。
下面将结合具体的例子来说明本申请提供的反馈信息传输的方法。
如图9所示，图9是本申请一个实施例的时间窗的示意图。在图9中，以第一下行消息为第一PDSCH、时间窗的时域单位为时隙。该第一反馈信息为第一PDSCH的第一ACK或NACK信息，第二下行消息为第二PDSCH、该第二反馈信息为第二PDSCH的第二ACK或NACK信息，网络设备预配置的第一PDSCH对应的第一ACK或NACK信息的时域位置为时隙n-1上的部分符号为例进行说明。
如图9所示，第一时间窗的时域范围为时隙n至时隙n+3，包括4个时隙。第一时间窗包括3个上行传输资源，分别是时隙n上的用于传输第三PDSCH对应的第三ACK或 NACK信息的上行传输资源，时隙n+2上的用于传输第四PDSCH对应的第四ACK或NACK信息的上行传输资源，以及时隙n+3上的用于传输PUSCH的上行传输资源。第三PDSCH与上述的第一PDSCH和第二PDSCH不同，第三ACK或NACK信息也与上述的第一ACK/NACK信息和第一ACK/NACK信息不同。第四PDSCH与上述的第一PDSCH和第二PDSCH也不同，并且，第三ACK/NACK信息与第四ACK/NACK信息也不同。
终端设备已经接收到该第二PDSCH。第二时间窗的时域范围为时隙n+2至时隙n+5，包括4个时隙。第二时间窗包括3个上行传输资源。分别是时隙n+2上的用于传输第四ACK或NACK信息上行传输资源，时隙n+3上的用于传输PUSCH的上行传输资源，以及时隙n+5上的用于传输CSI的上行传输资源。第一时间窗和第二时间窗在同一个信道上。第一时间窗和第二时间窗时域上部分重叠。重叠的上行传输资源为用于传输第四ACK或NACK信息上行传输资源以及用于传输PUSCH的上行传输资源。
如图9所示，如果终端设备在时隙n+2上(或者时隙n+2之前)接入信道(接入信道的结束时刻早于时隙n+2的上行传输资源开始时刻)，则终端设备也可以在时隙n+2上的上行传输资源上发送该第一反馈信息。由于时隙n+2上的上行传输资源还可以用来传输第二反馈信息，因此，终端设备可以在时隙n+2上发送第一反馈信息(第一ACK或NACK信息)和第二反馈信息(第二ACK或NACK信息)，在这种情况下，终端设备需要确定在时隙n+2上的上行传输资源(第一上行传输资源)发送哪一个或者两个。即终端设备在该第一反馈信息和反馈信息中确定第三反馈信息。第三反馈信息可以是该反馈信息和第反馈信息中的一个，也可以是该第一反馈和第二反馈信息，也可以是第一反馈和第二反馈信息进行逻辑与之运算后的信息。然后在时隙n+2上的上行传输资源发送该第三反馈信息和第二ACK或NACK信息的联合信息。
如图9所示，如果终端设备在时隙n+3上(或者时隙n+3之前)才接入信道(接入信道的结束时刻早于时隙n+2的上行传输资源开始时刻)，则终端设备可以在时隙n+3上的上行传输资源上发送该第一反馈信息(第一ACK或NACK信息)，也可以在时隙n+3上的上行传输资源上发送该第二反馈信息(第二ACK或NACK信息)。在这种情况下，终端设备也需要在该第一反馈信息和第二反馈信息中确定第三反馈信息。然后在时隙n+3上的上行传输资源发送该第三反馈信息和PUSCH的联合信息。如果终端设备在时隙n+3之后在接入信道(接入信道的结束时刻晚于时隙n+3的上行传输资源开始时刻)，终端设备便不能向网络设备发送该第一反馈信息(第一ACK或NACK信息)。
如图9所示，如果终端设备时隙n+5上(或者时隙n+5之前)才接入信道(接入信道的结束时刻早于时隙n+5的上行传输资源开始时刻)，终端设备可以在时隙n+5上的上行传输资源上向网络设备发送第二反馈(第二ACK或NACK信息)和CSI的联合信息。
应理解，图9只是示例性的，不应该对本申请的实施例造成限制。例如，上述的第一时间窗可以包括该预配置的用于传输第一ACK或NACK信息上行传输资源，第二时间窗也可以包括该预配置的用于传输第二ACK或NACK信息上行传输资源，该第一时间窗和/或第二时间窗还可以包括更多的时隙，该第一时间窗和/或第二时间窗可以是更长的时间长度，该第一时间窗和/或第二时间窗还可以包括的上行传输资源还可以是用于传输其他上行信息的上行传输资源、该第一时间窗和第二时间窗在时域和/或频域上还可以不重叠。本申请实施例在此不作限制。
作为一种可能的实现方式，该第三反馈信息为该第一反馈信息和该第二反馈信息中时域位置较早或者较晚的反馈信息；
或者，该第三反馈信息为该第一时间窗和第二时间窗中的上行传输资源较少的时间窗对应的反馈信息，该第二时间窗对应与该第二反馈信息，该第二时间窗包括至少一个上行传输资源，每个上行传输资源用于传输上行信息；
或者，该第三反馈信息为该第一时间窗和该第二时间窗分别包括的、在该终端设备接入信道的结束时刻后剩余的上行传输资源较少的时间窗对应的反馈信息。
或者，该第三反馈信息为该第一时间窗和该第二时间窗分别包括的、在该终端设备接入该信道的结束时刻后剩余的时间单元较少的时间窗对应的反馈信息。
或者，该第三反馈信息为第一反馈信息和第二反馈信息中优先级较高的反馈信息。
具体而言，当第一上行传输资源只能承载该第一反馈信息和第二反馈信息中的一个时，即第三反馈信息是该第一反馈信息和第二反馈信息中的一个。
作为一种具体的实现方式，该第三反馈信息为该第一反馈信息和该第二反馈信息中时域位置较早或者较晚的反馈信息。以该第一反馈信息和该第二反馈信息分别为上述的第一ACK或者NACK信息和该第二ACK或者NACK信息为例进行说明。则该第三反馈信息为该第一ACK或者NACK信息和该第二ACK或者NACK信息中时域位置较早或者较晚的ACK或者NACK信息。即第三反馈信息为预配置的第一ACK或者NACK信息和该第二ACK或者NACK信息的时域位置中较早或者较晚的ACK或者NACK信息。这样可以使得网络设备获知较早发送的数据的反馈。提高通信效率。如果需要将较晚到的第二ACK或者NACK信息反馈给网络设备，则第三反馈信息为第二ACK或者NACK信息，这样可以使得网络设备及时获知的发送的数据的反馈，减少收到反馈信息所用的时间，进一步的降低反馈时延，提高通信效率。
作为另一种具体的实现方式，该第三反馈信息为该第一时间窗和第二时间窗中包括的上行传输资源较少的时间窗对应的反馈信息。以该第一反馈信息和该第二反馈信息分别为上述的第一ACK或者NACK信息和该第二ACK或者NACK信息为例进行说明。例如，第一时间窗包括5个上行传输资源，第一时间窗是为第一ACK或者NACK信息配置的。第二时间窗包括3个上行传输资源，第二时间窗是为第二ACK或者NACK信息配置的。则第三反馈信息为第二ACK或者NACK信息。这样可以使得网络设备及时获知的发送的数据的反馈，减少收到反馈信息所用的时间，进一步的降低反馈时延。
作为另一种具体的实现方式，该第三反馈信息为该第一时间窗和该第二时间窗分别包括的、在该终端设备接入该信道的结束时刻后剩余的上行传输资源较少的时间窗对应的反馈信息。例如，以图9所示的为例进行说明。如果终端设备在时隙n+3上(传输PUSCH的上行传输资源的时域位置之前)接入信道，对于第一时间窗而言，在接入该信道的结束时刻后剩余的上行传输资源个数为1个。而对于第二时间窗而言，在接入该信道的结束时刻后剩余的上行传输资源个数为2个。在接入该信道后剩余的上行传输资源较少的时间窗为第一时间窗，与第一时间窗对应的第一ACK或者NACK信息，即第三反馈信息为第一ACK或者NACK信息。这样可以使得网络设备及时获知的发送的数据的反馈，减少收到反馈信息所用的时间，进一步的降低反馈时延。
作为另一种具体的实现方式，该第三反馈信息为该第一时间窗和该第二时间窗分别包 括的、在该终端设备接入该信道的结束时刻后剩余的时间单元较少的时间窗对应的反馈信息。例如，以图9所示的为例进行说明。如果终端设备在时隙n+2上接入信道，对于第一时间窗而言，在接入该信道的结束时刻后剩余的时间单元(时隙)的个数为1个(为时隙n+3)。而对于第二时间窗而言，在接入该信道的结束时刻后剩余的时间单元(时隙)的个数为3个(为时隙n+3、n+4、n+5)。对于终端设备通过新的DCI在时间窗内为该反馈信息调度新的上行传输的资源的情况下，终端设备通过新的DCI在时间窗内为该反馈信息调度新的上行传输的资源可以理解为：以图8所示的第二时间窗为例进行说明，如果终端设备在时隙n+2上接入信道后，网络设备又通过新的DCI在第二时间窗内为该第二反馈信息调度新的上行传输的资源，例如，该新的上行传输的资源为时隙n+4内的上行传输资源，或者为时隙n+2内其他可用的上行传输资源，或者为时隙n+3内其他可用的上行传输资源等。在接入信道后时间窗内剩余的时间单元的个数越少，意味着网络设备通过新的DCI在该时间窗内为该反馈信息调度新的上行传输的可能性越小，即潜在的发送反馈信息的机会就越小。这样可以使得网络设备及时获知的发送的数据的反馈，减少收到反馈信息所用的时间，进一步的降低反馈时延。
应理解，在本申请实施例中，时间单元可以是一个时隙或者一个符号，或者还可以是其他的时域单位。时间窗内包括的上行传输资源的个数可以小于时间窗内包括的时间单元的个数，也可以大于或者等于时间窗内包括的时间单元的个数。
作为另一种具体的实现方式，该第三反馈信息为第一反馈信息和第二反馈信息中优先级较高的反馈信息。以该第一反馈信息和该第二反馈信息分别为上述的第一ACK或者NACK信息和该第二ACK或者NACK信息为例进行说明。假设第一ACK/NACK信息的优先级高于该第二ACK/NACK信息的优先级，则该第三反馈信息为第一ACK/NACK信息。
应理解，在本申请实施例中，除了利用上述的几种方式确定第三反馈信息之外，还可以利用其他方式确定该第三反馈信息。例如，可以根据第一反馈信息和第二反馈信息所占的传输资源的大小来确定该第三反馈信息是第一反馈信息或者是第二反馈信息。本申请实施例在此不作限制。
可选的，作为一个实施例中，该第一时间窗和/或该第二时间窗包括的上行传输资源为：用于传输CSI的上行传输资源、用于传输PUSCH的上行传输资源、用于传输混合自动重传ACK或者NACK信息的上行传输资源中的至少一个。
具体而言，由于第一时间窗和第二时间窗均包括一个或者多个上行传输资源，每个上行传输资源都用于传输上行信息。第一时间窗内的上行传输资源可以是用于传输CSI的上行传输资源、用于传输PUSCH的上行传输资源、用于传输ACK或者NACK信息的上行传输资源中的至少一个。上述的几种上行传输资源的时频配置都是网络设备预先通过配置信息或者指示信息通知给终端设备的。例如，第一时间窗内的包括2个上行传输资源，分别为是用于传输PUSCH的上行传输资源、用于传输CSI的上行传输资源，这三种信息的传输资源是网络设备预先配置给终端设备的，即终端设备是预先知道传输PUSCH的上行传输资源、传输PUCCH的上行传输资源、传输CSI的上行传输资源的时频位置。同样的，第二时间窗也可以包括上述的多个上行传输资源中的至少一个。
可选的，第一时间窗和第二时间窗可以包括一个或者多个相同的上行传输资源。当然， 第一时间窗和第二时间窗也可以不包括相同上行传输资源，即第一时间窗和第二时间窗在时域上不重叠。可选的，第一时间窗和第二时间窗也可以在频域上不重叠。
应理解，在本申请实施例中，该第一时间窗和/或该第二时间窗包括的多个上行传输资源除了为上述的几种上行传输资源外，还可以是其他上行传输资源，例如，传输调度请求(scheduling request，SR)的上行传输资源。本申请实施例在此不作限制。
可选的，作为一个实施例，图10是本申请另一个实施例反馈信息传输的方法的示意性交互图。如图10所示，该方法200还包括：
S260，该终端设备向该网络设备发送指示信息。该指示信息用于指示该终端设备在该第一上行传输资源上发送该联合信息。相应的，该网络设备接收该指示信息。
具体而言，该第一时间窗包括多个上行传输资源，每个上行传输资源用于传输上行信息。因此，在终端设备确定多个上行传输资源后的第一传输资源后，便可以在第一传输资源上向网络设备发送该联合信息。因此，需要告知网络设备在第一传输资源上向网络设备发送该联合信息。具体的，可以向网络设备发送指示信息，该指示信息用于指示该终端设备在该第一上行传输资源上承载该联合信息。相应的，网络设备在接收到该指示信息后，便可以根据指示确定第一上行传输资源，并且只在第一上行传输资源检测该联合信息，减少了网络设备进行检测的范围，使得网络设备可以准确的确定传输联合信息的上行传输资源。降低网络设备的资源消耗，提高通信效率。
具体的，终端设备可以通过以下的形式的指示信息通知网络设备。
作为一种可能的实现方式，该第一上行信息的解调参考信号(demodulation reference signal，DMRS)的循环移位值为K，该K用于指示该终端设备在该第一上行传输资源中传输该联合信息。
由于第一上行传输资源传输的为第一上行信息和第一反馈信息的联合信息。因此，终端设备和网络设备可以预先定义某一个上行信息的DMRS循环移位值为K，该K用于指示在该终端设备该第一上行传输资源中传输该联合信息。即预定义第一上行信息的DMRS循环移位值为K。终端设备在确定了第一上行传输资源后，可以将第一上行传输资源传输的DMRS循环移位值设置为K。网络设备在检测到某一个上行资源的DMRS循环移位值为K时，便可以确定该上行信息所在的上行传输资源为该第一上行资源，第一上行资源承载该联合信息。
作为另一种可能的实现方式，该第一上行信息可以通过第一无线网络临时标识(radio network temporary identity，RNTI)进行加扰，该第一RNTI用于指示该终端设备在该第一上行资源中传输该联合信息。由于第一上行传输资源传输的为第一上行信息和第一反馈信息的联合信息。因此，终端设备和网络设备可以预先定义联合信息使用一种特殊的RNTI进行加扰的，即预定义联合信息是利用第一RNTI进行加扰的。终端设备在确定了第一上行传输资源后，可以将第一上行传输资源传输的联合信息利用第一RNTI进行加扰。网络设备在检测到某一个上行资源上承载的上行信息是利用第一RNTI进行加扰时，便可以确定该上行信息所在的上行传输资源为该第一上行资源，第一上行资源承载该联合信息。
应理解，上述的两种具体的指示方式可以看成隐式指示的方式，即网络设备和终端设备可以预定义上行信息中某些特定的字段或者特殊的加扰方式来区分该第一上行信息，进而确定出传输该联合信息的第一上行传输资源。终端设备可以选择不同的资源来隐式指示 承载的联合信息的上行传输资源，网络设备通过在不同上行传输资源上进行能量检测能量等，判断承载联合信息的上行传输资源以及承载的联合信息是哪一种。除了上述的两种可能的指示方式之外，还可以利用其他的隐式的指示方式来指示在该第一上行传输资源中传输该联合信息。本申请实施例在此不作限制。
还应理解，终端设备可以利用显示的指示方式通知网络设备哪个上行传输资源是第一上行传输资源。例如，在确定该第一上行传输资源后，可以向网络设备发送指示信息，该指示信息明确告知网络设备哪个上行传输资源是第一上行传输资源。网络设备接收到该指示信息后，便可以确定第一上行传输资源，从而正确接收该联合信息。
可选的，作为一个实施例，网络设备也可以通过新的信令(例如新的RRC信令和/或DCI中增加字段)指示终端设备在哪一个上行传输资源上复用，即在哪一个上行传输资源上联合传输。或者指示终端设备在哪些上行资源上可以复用。即网络设备可以直接通知该终端设备哪个上行传输资源为该第一上行传输资源，可以用来承载该联合信息。
应理解，上述的网络设备直接通知该终端设备在哪个上行传输资源进行联合传输的方式中，网络设备指示的上行传输资源可以在上述的第一时间窗的内包括，也可以不在上述的第一时间窗的内包括。本申请在此不作限制。
还应理解，在本申请的各个实施例中，第一、第二等只是为了表示多个对象是不同的。例如第一时间窗和第二时间窗只是为了表示出不同的时间窗。而不应该对时间窗的本身产生任何影响，上述的第一、第二等不应该对本申请的实施例造成任何限制。
还应理解，上述只是为了帮助本领域技术人员更好地理解本申请实施例，而非要限制本申请实施例的范围。本领域技术人员根据所给出的上述示例，显然可以进行各种等价的修改或变化，例如，上述方法200某些步骤可以是不必须的，或者可以新加入某些步骤等。或者上述任意两种或者任意多种实施例的组合。这样的修改、变化或者组合后的方案也落入本申请实施例的范围内。
还应理解，上文对本申请实施例的描述着重于强调各个实施例之间的不同之处，未提到的相同或相似之处可以互相参考，为了简洁，这里不再赘述。
还应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
还应理解，本申请实施例中，“预先设定”、“预先定义”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
还应理解，本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便，不应构成特别的限定，各种方式、类别、情况以及实施例中的特征在不矛盾的情况下可以相结合。
还应理解，在本申请的各个实施例中，如果没有特殊说明以及逻辑冲突，不同的实施例之间的术语和/或描述具有一致性、且可以相互引用，不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
上文中结合图1至图10详细描述了根据本申请实施例的反馈信息传输的方法，下面将结合图11至图16详细描述本申请实施例的通信装置。
图11是根据本申请一个实施例的通信装置300的示意性框图，该装置300可以对应 上述方法200中描述的终端设备，也可以是应用于终端设备的芯片或组件，并且，该装置300中各模块或单元分别用于执行上述方法200中终端设备所执行的各动作或处理过程，具体地，如图11所示，该装置300包括：通信单元310和处理单元320。
通信单元310，用于接收网络设备发送的第一下行消息；
处理单元320，用于确定传输第一上行信息的第一上行传输资源，第一上行传输资源为第一时间窗所包括的至少一个上行传输资源中的一个，该第一时间窗包括至少一个上行传输资源，至少一个上行传输资源中每个上行传输资源用于传输上行信息。
该通信单元310还用于在该第一上行传输资源上向该网络设备发送第一反馈信息和该第一上行信息的联合信息，该第一反馈信息响应于该第一下行消息。
本申请提供的通信装置，通过向该通信装置发送第一时间窗的时频配置，而第一时间窗内是包括多个由网络设备为其他上行信息配置的上行传输资源的。该通信装置可以在第一时间窗包括的多个上行传输资源中的第一上行资源上发送第一信息。即在第一上行传输资源上发送第一反馈信息和第一上行传输资源预配置的第一上行信息的联合信息。可以很大程度上增加第一反馈信息在非授权频谱上的反馈机会，降低通信装置出现没有资源发送反馈信息的情况的发生，避免网络设备和通信装置之间因为反馈信息不能传输出现的通信问题。
可选的，通信单元310可以包括接收单元(模块)和发送单元(模块)，用于执行方法200以及图2、图6、图8和图10中终端设备接收信息和发送信息的步骤。可选的，通信装置300还可以包括存储单元330，用于存储通信单元310和处理单元320执行的指令。通信单元310、处理单元320和存储单元330通信连接，存储单元330存储指令，处理单元320用于执行存储单元330存储的指令，通信单元310用于在处理单元320的驱动下执行具体的信号收发。
通信装置300是通信设备，也可以是通信设备内的芯片。当该通信装置是通信设备时，该处理单元可以是处理器，通信单元可以是收发器。该通信设备还可以包括存储单元，该存储单元可以是存储器。该存储单元用于存储指令，该处理单元执行该存储单元所存储的指令，以使该通信设备执行上述方法。当该通信装置是通信设备内的芯片时，该处理单元可以是处理器，通信单元可以是输入/输出接口、管脚或电路等；该处理单元执行存储单元所存储的指令，以使该通信装置执行上述方法200中由终端设备所执行的操作，该存储单元可以是该芯片内的存储单元(例如，寄存器、缓存等)，也可以是该通信设备内的位于该芯片外部的存储单元(例如，只读存储器、随机存取存储器等)。
本领域技术人员可以清楚地了解到，当通信装置300所执行的步骤以及相应的有益效果可以参考上述方法200中终端设备的相关描述，为了简洁，在此不再赘述。
应理解，通信单元310可以由收发器实现，处理单元320可由处理器实现。存储单元可以由存储器实现。如图12所示，通信装置400可以包括处理器410、存储器420和收发器430。
图11所示的通信装置300或图12所示的通信装置400能够实现前述方法200以及图2、图6、图8和图10中终端设备执行的步骤。类似的描述可以参考前述对应的方法中的描述。为避免重复，这里不再赘述。
还应理解，图11所示的通信装置300或图12所示的通信装置400可以为终端设备。
图13是根据本申请一个实施例的通信装置500的示意性框图，该装置500可以对应上述方法200中描述的网络设备，也可以是应用于网络设备的芯片或组件，并且，该装置500中各模块或单元分别用于执行上述方法500中网络设备所执行的各动作或处理过程，具体地，如图13所示，该装置500包括：通信单元510和处理单元520。
通信单元510，用于向终端设备发送第一下行消息；
