图2是根据一示例性实施例示出的自动重传的指示方法的流程示意图，如图2所示，本公开实施例的自动重传的指示方法包括以下处理步骤：
步骤201，网络设备向用户设备发送第一信息。所述第一信息用于指示被调度的PDSCH是否在相同时域单元内共享同一LBT子带。
本公开实施例中，所述第一信息中包含第一指示符，所述第一指示符用于指示PDSCH在相同时域单元内是否共享同一LBT子带。所述第一指示符为第一值时，指示所述第一信息调度的PDSCH与所述第二信息调度的PDSCH在相同时域单元内共享同一LBT子带；所述第一指示符为第二值时，指示所述第一信息调度的PDSCH与所述第二信息调度的PDSCH在相同时域单元内不共享同一LBT子带。
作为一种示例，第一信息可以是DCI。在DCI中新增1比特字符作为指示字符，以指示多个DCI调度的PDSCH是否存在时间重叠且共享同一LBT子带的情况，当该位为1时，则表示当前DCI调度的PDSCH与另一DCI调度的PDSCH存在时间重叠且共享同一LBT子带的情况；当该位为0时，则表示当前DCI调度的PDSCH与另一调度的PDSCH在相同时域单元内不共享同一LBT子带。作为另一种方式，也可以是当该 位为0时，则表示当前DCI调度的PDSCH与另一DCI调度的PDSCH存在时间重叠且共享同一LBT子带的情况；当该位为1时，则表示当前DCI调度的PDSCH与另一调度的PDSCH在相同时域单元内不共享同一LBT子带。
在不考虑频带资源的情况下，在DCI中也可以新增两比特的指示符来指示PDSCH是否在相同时域单元内共享同一LBT子带的信息的情况，如当DCI中两指示位为“00”，表示当前DCI调度的PDSCH没有在相同时域单元内与其他PDSCH共享同一LBT子带。当DCI中两指示位为“01”，表示当前DCI调度的PDSCH与上一DCI调度的PDSCH在相同时域单元内不共享同一LBT子带，当DCI中两指示位为“10”，表示当前DCI调度的PDSCH与下一DCI调度的PDSCH在相同时域单元内不共享同一LBT子带。即当指示符包含的比特位较多时，不仅可以指示多PDSCH在相同时域单元内共享同一LBT子带的情况，还可以更进一步指示当前的DCI调度的PDSCH与哪个PDSCH在相同时域单元内共享同一LBT子带。
本公开实施例中，第一信息也可以是DCI的加扰序列，通过DCI的加扰序列来指示被调度的PDSCH是否在相同时域单元内共享同一LBT子带。具体地，所述网络设备向用户设备发送第一信息之前，利用加扰序列对所述第一信息进行加扰；所述加扰序列中包含PDSCH是否在相同时域单元内共享同一LBT子带的信息。在一个实施例中，所述加扰序列指示第三值时，指示所述第一信息调度的PDSCH与所述第二信息的信息调度的PDSCH在相同时域单元内共享同一LBT子带；所述加扰序列指示第四值时，指示所述第一信息调度的PDSCH与所述第二信息调度的PDSCH在相同时域单元内不共享同一LBT子带。
作为一种示例，当多个DCI调度的多个PDSCH在相同时域单元内 不共享同一LBT子带时，采用第一加扰序列对DCI进行加扰，对多个DCI调度的多个PDSCH在相同时域单元内共享同一LBT子带时，采用第一加扰序列对DCI进行加扰；如第一加扰序列为小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)；第二加扰序列可以为在C-RNTI中设置为2比特隐式指示位，如采用01作为第二加扰序列的最后两位循环冗余校验(Cyclic Redundancy Check，CRC)位，而第一加扰序列和第二加扰序列的CRC位的信息事先通知UE，若UE利用第二加扰序列解扰DCI正确，表示当前DCI调度的PDSCH与另一DCI调度的PDSCH在相同时域单元内共享同一LBT子带的信息。若采用第一加扰序列对DCI解扰正确，则DCI调度的PDSCH在相同时域单元内不共享同一LBT子带。当然，上述第二加扰序列中所设置的CRC指示字符也可以是“10”、“00”或“11”等。
当本公开实施例通过加扰序列来隐式指示DCI调度的PDSCH是否在相同时域单元内共享同一LBT子带的信息时，也可以通过加扰序列中的设置的指示字符来进一步指示DCI调度的PDSCH具体与哪个PDSCH在相同时域单元内共享同一LBT子带。如第二加扰序列中所设置的CRC指示字符，当采用01作为第二加扰序列的最后两位CRC时，表示当前DCI调度的PDSCH与上一DCI调度的PDSCH在相同时域单元内共享同一LBT子带；当采用10作为第二加扰序列的最后两位CRC时，表示当前DCI调度的PDSCH与下一DCI调度的PDSCH在相同时域单元内共享同一LBT子带。
在本公开实施例中，所述方法还包括：所述网络设备接收所述用户设备发送的PDSCH解调结果指示信息，确定在相同时域单元内共享同一LBT子带的PDSCH时，基于所述第一指示符或所述加扰序列和所述PDSCH解调结果指示信息，确定解调失败的PDSCH并重传。
图3是根据一示例性实施例示出的自动重传的指示方法的流程示意图，如图3所示，本公开实施例的自动重传的指示方法包括以下步骤：
步骤301，用户设备接收网络设备发送的第一信息。
所述第一信息用于指示第一PDSCH是否在相同时域单元内共享同一LBT子带。
具体地，本公开实施例中，所述第一信息中包含第一指示符，所述第一指示符用于指示PDSCH在相同时域单元内是否共享同一LBT子带。所述第一指示符为第一值时，指示所述第一信息调度的PDSCH与所述第二信息调度的PDSCH在相同时域单元内共享同一LBT子带；所述第一指示符为第二值时，指示所述第一信息调度的PDSCH与所述第二信息调度的PDSCH在相同时域单元内不共享同一LBT子带。作为一种示例，第一信息可以是DCI。在DCI中新增1比特字符作为指示字符，以指示多个DCI调度的PDSCH是否存在时间重叠且共享同一LBT子带的情况，当该位为1时，则表示当前DCI调度的PDSCH与另一DCI调度的PDSCH存在时间重叠且共享同一LBT子带的情况；当该位为0时，则表示当前DCI调度的PDSCH与另一调度的PDSCH在相同时域单元内不共享同一LBT子带。作为另一种方式，也可以是当该位为0时，则表示当前DCI调度的PDSCH与另一DCI调度的PDSCH存在时间重叠且共享同一LBT子带的情况；当该位为1时，则表示当前DCI调度的PDSCH与另一调度的PDSCH在相同时域单元内不共享同一LBT子带。在不考虑频带资源的情况下，在DCI中也可以新增两比特的指示符来指示PDSCH是否在相同时域单元内共享同一LBT子带的信息的情况，如当DCI中两指示位为“00”，表示当前DCI调度的PDSCH没有在相同时域单元内与其他PDSCH共享同一LBT子带。当DCI中两指示位为“01”，表示当前DCI调度的PDSCH与上一DCI调度的PDSCH在相同时域单元内不共享同一 LBT子带，当DCI中两指示位为“10”，表示当前DCI调度的PDSCH与下一DCI调度的PDSCH在相同时域单元内不共享同一LBT子带。即当指示符包含的比特位较多时，不仅可以指示多PDSCH在相同时域单元内共享同一LBT子带的情况，还可以更进一步指示当前的DCI调度的PDSCH与哪个PDSCH在相同时域单元内共享同一LBT子带。
在本公开实施例中，第一信息也可以是DCI的加扰序列，通过DCI的加扰序列来指示被调度的PDSCH是否在相同时域单元内共享同一LBT子带。具体地，所述网络设备向用户设备发送第一信息之前，利用加扰序列对所述第一信息进行加扰；所述加扰序列中包含PDSCH是否在相同时域单元内共享同一LBT子带的信息。在一个实施例中，所述加扰序列指示第三值时，指示所述第一信息调度的PDSCH与所述第二信息的信息调度的PDSCH在相同时域单元内共享同一LBT子带；所述加扰序列指示第四值时，指示所述第一信息调度的PDSCH与所述第二信息调度的PDSCH在相同时域单元内不共享同一LBT子带。作为一种示例，当多个DCI调度的多个PDSCH在相同时域单元内不共享同一LBT子带时，采用第一加扰序列对DCI进行加扰，对多个DCI调度的多个PDSCH在相同时域单元内共享同一LBT子带时，采用第一加扰序列对DCI进行加扰；如第一加扰序列为C-RNTI；第二加扰序列可以为在C-RNTI中设置为2比特隐式指示位，如采用01作为第二加扰序列的最后两位循环冗余校验(Cyclic Redundancy Check，CRC)位，而第一加扰序列和第二加扰序列事先通知给UE，若UE利用第二加扰序列解扰DCI正确，表示当前DCI调度的PDSCH与另一DCI调度的PDSCH在相同时域单元内共享同一LBT子带的信息。若采用第一加扰序列对DCI解扰正确，则DCI调度的PDSCH在相同时域单元内不共享同一LBT子带。当然，上述第二加扰序列中所设置的CRC指示字符也可以是“10”、“00”或“11”等。
当本公开实施例通过加扰序列来隐式指示DCI调度的PDSCH是否在相同时域单元内共享同一LBT子带的信息时，也可以通过加扰序列中的设置的指示字符来进一步指示DCI调度的PDSCH具体与哪个PDSCH在相同时域单元内共享同一LBT子带。如通过在第二加扰序列中设置CRC来指示，当采用01作为第二加扰序列的最后两位CRC时，表示当前DCI调度的PDSCH与上一DCI调度的PDSCH在相同时域单元内共享同一LBT子带；当采用10作为第二加扰序列的最后两位CRC时，表示当前DCI调度的PDSCH与下一DCI调度的PDSCH在相同时域单元内共享同一LBT子带。
步骤302，基于所述第一信息解调所述第一信息调度的第一PDSCH，确定所述第一PDSCH的解调结果。
用户设备基于DCI对PDSCH进行解调，基于DCI本身或DCI的加扰序列确定当前的PDSCH是否与其他PDSCH在相同时域单元内共享同一LBT子带。当确定与其他PDSCH在相同时域单元内共享同一LBT子带的PDSCH解调失败时，需要向网络设备清楚指示哪个PDSCH解调成功，哪个PDSCH解调失败，以便于网络设备能够基于PDSCH解调结果指示信息发起解调失败的PDSCH的重传。
本公开实施例中，对于在相同时域单元内共享同一LBT子带的PDSCH，由于多个PDSCH占用了共同的LBT子带资源，会导致指示码本指示不清楚的情况，而通过将多个PDSCH占用了共同的LBT子带资源的情形向用户设备通知，用户设备可以基于具体的解调结果向网络设备反馈准确的指示码本，从而便于网络设备基于指示码本进行PDSCH的重传。
步骤303，根据所述第一信息向所述网络设备发送PDSCH解调结果指示信息。
本公开实施例中，与所述第一PDSCH在相同时域单元内可能不存在共享同一LBT子带的第二PDSCH，此时直接按现有的码本指示方式进行指示即可。确定与所述第一PDSCH在相同时域单元内存在共享同一LBT子带的第二PDSCH时，根据所述第一PDSCH和所述第二PDSCH的解调结果，发送包含所述第一PDSCH和所述第二PDSCH解调结果的指示信息。如果与所述第一PDSCH在相同时域单元内存在共享同一LBT子带的第二PDSCH的解调结果，则根据具体的解调结果，向网络设备指示相应的解调结果指示信息。
所述用户设备根据DCI的具体取值，确定所述第一PDSCH和所述第二PDSCH在相同时域单元内共享同一LBT子带的频域关系。具体地，当多个PDSCH对应的DCI中的相应指示位的值如为“1”时，该多个PDSCH在相同时域单元内共享同一LBT子带。即DCI取值为第一值时，指示多个PDSCH在相同时域单元内共享同一LBT子带。
用户设备利用包含所述第三值或所述第四值的所述加扰序列对所述第一信息进行解扰，解扰成功后确定所述第二信息中包含第三值或第四值，根据所述第三值或所述第四值确定PDSCH与其他PDSCH在相同时域单元内共享同一LBT子带的频域关系。
以下通过具体示例，进一步阐明本公开实施例的技术方案的实质。
Figure PCTCN2020105616-appb-000001
表1
如表1所示，示出了PDSCH在不同的频带SB的承载关系，表1中最后一行表示UE向网络设备反馈的半静态码本的指示信息。Case1中，PDSCH1承载于SB0的LBT子带，半静态码本为指示SB0-SB3的四个LBT子带的PDSCH解调结果。由于只有SB0的LBT子带中承载有PDSCH1，因此码本为“0000”或“1000”，其中，“1000”针对PDSCH1的解调成功，“0000”表示针对PDSCH1的解调失败。Case2、Case3中的情况与Case1类似，只是PDSCH占用的LBT子带资源有所不同，针对PDSCH的调度信息DCI的占用资源也有所不同。本公开实施例中，主要是关注有时间重叠且共享同一子带的PDSCH，如表1中的Case4的情形，当UE在SB0上接收到PDCCH 5并且正确解码其在SB0和SB2上调度的PDSCH 5，但由于强干扰导致UE在SB1上未接收到PDCCH 6及其调度在SB1和SB2上传输的PDSCH 6时，此时UE会认为在该种情况下只传输了PDCCH 5及其对应的PDSCH 5，由于UE侧正确解码PDSCH5，因此向网络设备侧报告1100，而网络设备侧在接收到1100时，会认为由PDCCH 5和PDCCH 6调度的PDSCH 5、PDSCH6均被UE正确接收，因此不会重新传输PDSCH6。在这种情况下，会导致PDSCH 6数据丢失，进而导致通信系统的可靠性下降。本公开实施例正是针对这种多个PDSCH在相同时域单元内共享同一LBT子带的情形，通过对DCI或DCI加扰序列向UE指示，有两个PDSCH在相同时域单元内共享同一LBT子带，需要针对这种情况对PDSCH解调情况进行上报。具体地，对DCI采用两种类别的加扰方式来区分多个PDSCH在相同时域单元内共享同一LBT子带的情况。在网络设备侧，由于网络设备在调度DCI5时已知其与DCI6需要调度的PDSCH6存在时间重叠且共享同一LBT子带(SB1)，因此对DCI5采用扩展的加扰序列进行加扰(C-RNTI+10)，表示当前DCI调度的PDSCH与下一DCI6调度的PDSCH6存在在时域单元内共享LBT子带的情况；扩展的加扰序列为C-RNTI+01 时，表示当前DCI调度的PDSCH与上一DCI调度的PDSCH存在在时域单元内共享LBT子带的情况。在用户设备侧，首先采用C-RNTI解扰DCI5，由于此时出现解扰错误的情况，因此采用扩展的加扰序列进行解扰，利用C-RNTI+10或C-RNTI+01对DCI5再次解扰，用户利用C-RNTI+10正确解扰后，得知该DCI调度的PDSCH与下一DCI调度的PDSCH存在时间重叠且共享同一LBT子带的情况。那么对于case4，对于SB0子带上的HARQ反馈，根据PDSCH5的解码情况设置其HARQ内容，对于共享LBT子带(SB1)，综合考虑其与另一PDSCH6的解码情况，在PDSCH6丢失的情况下，对于SB1(虚线框)子带上的HARQ反馈，由于PDSCH6丢失，因此综合考虑PDSCH5的解码结果为ACK，PDSCH6的解码结果为NACK，即case4的HARQ反馈内容为1000。由于PDSCH5所在SB0子带上的反馈内容为1，则认为PDSCH5已经正确解码，因此SB1上的0表示SB1上的PDSCH5解码正确，PDSCH6解码错误，网络设备仅重传PDSCH6对应的数据。
Figure PCTCN2020105616-appb-000002
表2
如表2所示，为另一示例的情况，对于存在时间重叠且共享同一LBT子带的PDSCH6和PDSCH5，在网络设备侧，由于在调度DCI6时已知其与DCI5调度的PDSCH5存在时间重叠且共享同一LBT子带(SB1)，因此对DCI6采用扩展的加扰序列(C-RNTI+01)进行加扰，表示当前DCI6调度的PDSCH6与上一DCI5调度的PDSCH5存在重叠且共享的情况；在用户设 备侧，由于DCI5完全错过，用户设备采用C-RNTI解扰DCI6，由于此时出现解扰错误的情况，因此采用扩展的加扰序列，如首先尝试将C-RNTI+01作用于CRC最后两位进行解扰，UE正确解扰后确定该DCI6调度的PDSCH6与上一DCI调度的PDSCH存在时间重叠且共享同一LBT子带的情况。对于case4，对于SB2子带上的HARQ反馈，根据PDSCH6的解码情况设置其HARQ内容，对于共享LBT子带(SB1)，综合考虑其与另一PDSCH5的解码情况，在PDSCH5丢失的情况下，对于SB1(虚线框)子带上的HARQ反馈，由于PDSCH5丢失，因此综合考虑PDSCH6的解码结果为ACK，以及PDSCH5的解码结果为NACK，case4的HARQ反馈内容为0010。由于PDSCH6所在SB2子带上的反馈内容为1，则认为PDSCH6已经正确解码，因此SB1上的0表示SB2上的PDSCH6解码正确，PDSCH5解码错误，网络设备仅重传PDSCH5对应数据。
本公开实施例中，当在DCI中直接设置扩展指示字符来指示该DCI调度的PDSCH与其他的PDSCH在相同时域单元内共享同一LBT子带时，通过对DCI进行解扰后读取对应指示位的指示字符的值，根据指示字符确定DCI调度的PDSCH与其他的PDSCH是否在相同时域单元内共享同一LBT子带，根据共享LBT子带的解码情况以及解码失败的PDSCH标号，按前述的加扰序列所示示例进行HARQ反馈，以使网络设备准确确定待重传的PDSCH。作为一种实现方式，可以在DCI中设置两个指示位，像前述表1、表2所示的方式来指示在相同时域单元内共享同一LBT子带PDSCH的解调情况。由于指示方式完全相同，这里不再赘述。当DCI中设置一比特指示字符来指示在相同时域单元内共享同一LBT子带PDSCH时，如当DCI为扩展的DCI时，指示当前的DCI调度的PDSCH与其他的PDSCH在相同时域单元内共享同一LBT子带，如果DCI为非扩展DCI，则指示该DCI调度的PDSCH与其他的PDSCH不在相同时域单元内共享同一LBT子带。 当扩展指示位为“0时”，指示当前的DCI调度的PDSCH与上一DCI调度的PDSCH在时间重叠且共享同一LBT子带，当扩展指示位为“1时”，指示当前的DCI调度的PDSCH与下一DCI调度的PDSCH在时间重叠且共享同一LBT子带。
