Description

一种上行信道的传输方法、装置和终端
交叉引用
本申请要求在2022年11月07日提交中国专利局、申请号为202211386337.1、发明名称为“一种上行信道的传输方法、装置和终端”的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于通信技术领域,具体涉及一种上行信道的传输方法、装置和终端。
背景技术
在新空口(New Radio,NR)系统的多播广播业务(Multimedia Broadcast Service,MBS)中,针对多播下行信道(如物理下行链路共享通道(Physical Downlink Shared Channel,PDSCH)或物理下行链路控制信道(Physical Downlink Control Channel,PDCCH))支持两种混合自动重传请求应答(Hybrid Automatic Repeat request-ACKnowledgement,HARQ-ACK)反馈模式:第一种是肯定应答/否定应答(HARQ-ACK/NACK)反馈模式,第二种是仅反馈否定应答(HARQ NACK-only)反馈模式。
在HARQ-ACK/NACK反馈模式中,终端(User Equipment,UE)成功解码多播下行信道,则反馈ACK,否则反馈NACK。
在HARQ NACK only反馈模式中,UE在成功解码多播下行信道时不反馈ACK,在没有成功解码时反馈NACK信息。如果需要反馈多个下行信道的HARQ-ACK信息,则在HARQ-ACK信息所有值都是ACK时,不传输承载HARQ-ACK的PUCCH。也就是说,只有在HARQ-ACK信息包含NACK时,UE才传输承载HARQ-ACK的PUCCH。
由于在同一时域资源上,UE可能被调度或被配置传输多个上行信道,例如,同时被调度或被配置传输承载HARQ-ACK的物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)和承载调度请求(Scheduling Request,SR信息)的PUCCH等信道,但受峰值平均功率比(Peak to Average Power Ratio,PAPR)等因素的影响,UE在同一时域资源上能够传输的上行信道数量有限,因此,在第二种反馈模式下,当需要传输的多个上行信道在时域资源上重叠时,需要解决这多个上行信道之间的冲突。
发明内容

其中,所述第一方式包括下述至少一项:
将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃;

为了解决第二种反馈模式下时域资源重叠的多个上行信道之间的冲突,本申请实施例提出了一种上行信道的传输方法和装置,下面结合附图详细说明。
如图2所示,本申请实施例提出的一种上行信道的传输方法,该方法可以包括:
步骤201、在待传输的多个上行信道的时域资源发生重叠的情况下,终端按照第一方式对所述多个上行信道的传输进行处理。
其中,所述多个上行信道包括第一物理上行链路控制信道(Physical Uplink Control Channel,PUCCH),且所述多个上行信道还包括第二PUCCH和物理上行共享信道(Physical Uplink Shared Channel,PUSCH)中的至少一项,所述第一PUCCH上承载有第二种反馈模式下的混合自动重传请求应答HARQ-ACK信息,所述第二种反馈模式为仅反馈否定应答HARQ-NACK信息的反馈模式,所述第二PUCCH上承载有调度请求(Scheduling Request,SR)信息和信道状态信息(Channel State Information,CSI)中的至少一项。也就是说,本申请实施例述及的上行信道传输方法,针对的是HARQ NACK only反馈模式(所述第二种反馈模式)下,需要传输的多个上行信道在时域资源上重叠时,如何解决这多个上行信道之间的冲突的这一应用场景。
需要说明的是,所述多个上行信道的时域资源发生重叠包括所述多个上行信道中的部分或全部信道之间的部分或全部时域资源重叠,下文会举例说明此处暂不赘述。
其中,所述第一方式包括但不限于下述至少一项:
将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃;
将所述多个上行信道中时域资源重叠的至少两个上行信道复用至同一上行信道;
将所述多个上行信道中时域资源未重叠的信道单独传输。
可以理解,通过丢弃和复用等方式可很好地解决所述多个上行信道因时域资源发生重叠导致的冲突问题。
在一个例子中,所述多个上行信道可以是同一PUCCH重叠组(PUCCH overlapping group)内的多个信道。当然,所述多个上行信道也可以不属于同一PUCCH重叠组。
其中,确定PUCCH重叠组的过程,可包括:先在多个候选PUCCH中选择一个参考 PUCCH;将所述多个候选PUCCH中所有与所述参考PUCCH重叠的PUCCH和所述参考PUCCH,确定为一个PUCCH重叠组。
在多个候选PUCCH中选择一个参考PUCCH,包括下述方式之一:
1)将所述多个候选PUCCH中起始时间(如起始符号)最早的PUCCH选为参考PUCCH;
2)若所述多个候选PUCCH的起始时间(如起始符号)相同,则将所述多个候选PUCCH中持续时长最大(如符号数最多)的PUCCH选为参考PUCCH;
3)若所述多个候选PUCCH的起始时间(如起始符号)相同且持续时长(如符号数)相同,则在所述多个候选PUCCH中任选一个PUCCH作为参考PUCCH。
图3示出了两个PUCCH重叠组的示意图。如图3所示,一个时隙有多个PUCCH(包括PUCCH1、SR PUCCH1、CSI PUCCH1、SR PUCCH2和CSI PUCCH2),其中,承载有HARQ NACK only反馈模式下的HARQ ACK信息的PUCCH1的起始符号最早,将PUCCH1作为参考PUCCH,则SR PUCCH1、PUCCH1和CSI PUCCH1形成一个PUCCH重叠组;在剩余的PUCCH中,SR PUCCH2的起始符号最早,将SR PUCCH2作为另一个PUCCH重叠组的参考PUCCH,时域资源重叠的SR PUCCH2和CSI PUCCH2形成另一个PUCCH重叠组。
需要说明的是,上述PUCCH重叠组的确定是为了处理重叠的上行信道,当UE确定了一个重叠的PUCCH重叠组,组内的所有PUCCH将被一起处理得到一个PUCCH,例如所有PUCCH信道承载的上行链路控制信息(Uplink Control Information,UCI)复用或丢弃部分PUCCH信道。
无论所述多个上行信道是否属于同一PUCCH重叠组,若所述多个上行信道包括所述第二PUCCH,则所述第二PUCCH可包括下述两种情况:
(1)所述第二PUCCH包括SR PUCCH和CSI PUCCH,其中,所述SR PUCCH是承载SR信息的PUCCH,所述CSI PUCCH是承载CSI的PUCCH;
(2)所述第二PUCCH包括同时承载SR信息和CSI的PUCCH。
其中,所述SR信息包括肯定(positive)SR信息和否定(negative)SR信息中的至少一项。
可选的,若所述多个上行信道包括所述第二PUCCH,则所述第二PUCCH的数量可以是一个,也可以是多个。
可选的,若所述多个上行信道包括所述PUSCH,则所述PUSCH的数量可以是一个,也可以是多个。
可选的,如果所述多个上行信道包括多个第二PUCCH,所述第一PUCCH可以和部分第二PUCCH的时域资源重叠,和另一部分第二PUCCH的时域资源不重叠;或者,所述第一PUCCH和所有第二PUCCH的时域资源均重叠。
可选的,所述多个上行信道中包括的所述第一PUCCH、所述第二PUCCH和所述 PUSCH具有相同或不同的优先级和/或优先级索引。其中,各上行信道的优先级可以是网络侧设备指示或配置的,一个上行信道的优先级可包括高、低两个等级,高优先级可表示为:priority index=1,低优先级可表示为:priority index=0。
可选的,所述多个上行信道中包括的所述第一PUCCH、所述第二PUCCH和所述PUSCH具有相同的优先级和/或优先级索引。
进一步的,在按照第一方式对所述多个上行信道的传输进行处理时,若所述第一方式包括将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃,则所述将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃,包括:将所述多个上行信道中优先级低的至少一个上行信道丢弃;若所述第一方式包括将所述多个上行信道中时域资源重叠的至少两个上行信道复用至同一上行信道,则所述将所述多个上行信道中时域资源重叠的至少两个上行信道复用至同一上行信道,包括:将所述多个上行信道中时域资源重叠且优先级相同的至少两个上行信道复用至同一上行信道。
下面通过几个实施例对所述多个上行信道的重叠情况,以及这些重叠情况下的第一方式进行说明。
实施例一
若所述多个上行信道包括第一PUCCH和第二PUCCH,所述第二PUCCH包括SR PUCCH,所述SR PUCCH是承载有SR信息的PUCCH,则在所述多个上行信道的重叠情况包括:所述第一PUCCH仅与所述SR PUCCH的时域资源重叠,且所述SR PUCCH与除所述第一PUCCH外的其他上行信道的时域资源未重叠的情况下,所述第一方式可包括但不限于下述至少一项:
将所述第一PUCCH承载的HARQ-ACK信息丢弃,将所述SR PUCCH进行传输;
将所述SR PUCCH承载的SR信息丢弃,将所述第一PUCCH进行传输。
UE根据实现(例如随机)要么将所述第一PUCCH承载的HARQ-ACK信息丢弃,将所述SR PUCCH进行传输,要么将所述SR PUCCH承载的SR信息丢弃,将所述第一PUCCH进行传输。
可选的,所述SR信息可以是肯定的SR信息。可以理解,第一PUCCH与承载肯定的SR信息的PUCCH重叠,考虑到第一PUCCH可以是组公共的,无法将SR信息复用到第一PUCCH,或者说,复用方法较为复杂,因此UE可能不支持第一PUCCH和SR PUCCH的复用,而是通过UE实现,UE自己确定丢弃其中一个信道,传输另一个信道。
进一步的,上述“UE根据实现(例如随机)”的方法可应用于所述第一PUCCH与所述SR PUCCH的优先级和/或优先级索引相同的情况下。在所述第一PUCCH与所述SR PUCCH的优先级不同的情况下,终端选择丢弃所述第一PUCCH与所述SR PUCCH中优先级较低者,将所述第一PUCCH与所述SR PUCCH中优先级较高者进行传输。
可选的,第一PUCCH和SR PUCCH属于同一PUCCH重叠组,或者,第一PUCCH和SR PUCCH不属于同一PUCCH重叠组。
实施例二
如图4所示,若所述多个上行信道包括第一PUCCH和第二PUCCH,且所述第二PUCCH上同时承载有SR信息和CSI,则在所述第一PUCCH与所述第二PUCCH的时域资源重叠的情况下,所述第一方式可包括:
将所述第一PUCCH上承载的第二种反馈模式下的HARQ-ACK信息转换为第一种反馈模式下的HARQ-ACK信息,并将转换后的HARQ-ACK信息和所述第二PUCCH上承载的CSI和SR信息复用在同一PUCCH上传输;
其中,所述第一种反馈模式为反馈肯定应答ACK/否定应答NACK的反馈模式。
可选的,在实施例二中,所述SR信息可以是肯定的SR信息也可以是否定的SR信息。
可选的,所述SR信息可以是1或多比特。
可选的,在实施例二中,第一PUCCH和第二PUCCH属于同一PUCCH重叠组,或者,第一PUCCH和第二PUCCH不属于同一PUCCH重叠组。
可选的,在实施例二中,第一PUCCH和第二PUCCH具有相同的优先级和/或优先级索引。
例如,第一PUCCH与同时承载有CSI和SR信息的第二PUCCH的时域资源发生重叠,则UE可以将转换后的HARQ-ACK信息、CSI和SR信息复用在CSI PUCCH上传输。例如可以采用与复用没有对应调度DCI的HARQ-ACK和CSI报告相同的方式确定PUCCH。例如,如果只有一个CSI报告(report),则复用在该CSI报告对应的PUCCH上,如果有多个CSI报告,则复用在多CSI PUCCH资源列表(multi-CSI-PUCCH-ResourceList)配置的PUCCH上。或者,UE可以将转换后的HARQ-ACK信息、CSI和SR信息复用在多播PDSCH的第一种HARQ-ACK反馈模式或单播PDSCH HARQ-ACK反馈对应的PUCCH-config/PUCCH-configurationList配置的PUCCH上。
其中,所述第一种反馈模式为反馈肯定应答ACK/否定应答NACK的反馈模式。
在多播传输中,HARQ-ACK反馈方式有两种混合自动重传请求应答(Hybrid Automatic Repeat request-ACKnowledgement,HARQ-ACK)反馈模式:
第一种反馈模式(first HARQ-ACK reporting mode),是肯定应答/否定应答(HARQ-ACK/NACK)信息的反馈模式,具体的,UE成功解码多播下行信道,则反馈ACK信息,否则反馈NACK信息。
第二种反馈模式(second HARQ-ACK reporting mode),是仅反馈否定应答(HARQ NACK-only)信息的反馈模式,具体的,UE在成功解码多播下行信道时不反馈ACK信息,在没有成功解码时反馈NACK信息。如果需要反馈多个下行信道的HARQ-ACK信息,则在HARQ-ACK信息所有值都是ACK时,不传输承载HARQ-ACK的PUCCH。也就是说,只有在HARQ-ACK信息包含NACK时,UE才传输承载HARQ-ACK的PUCCH。
UE可以被配置一个或多个无线网络临时标识符(group Radio Network Temporary  Identity,G-RNTI)或G-CS-RNTI,网络侧设备可以针对每一G-RNTI/G-CS-RNTI配置多播PDSCH的反馈模式。基站可以配置PUCCH-config Multicast1/pucch-ConfigurationListMulticast1 or PUCCH-config Multicast2/pucch-ConfigurationListMulticast2,其中PUCCH-config Multicast1/pucch-ConfigurationListMulticast1用于第一种反馈模式的多播HARQ-ACK反馈,PUCCH-config Multicast2/pucch-ConfigurationListMulticast用于第二种反馈模式的多播HARQ-ACK反馈。
对于多播PDSCH的HARQ-ACK,如果其反馈模式是第二种反馈模式,为了支持一个PUCCH时隙反馈多个传输块(Transmission Block,TB)的否定应答信息,规范了mode 1和mode 2两种模式,其中,如果配置了mode 1(例如参数moreThanOneNackOnlyMode没有被配置时),UE将多比特HARQ-ACK转换为ACK//NACK反馈,并在ACK/NACK对应的PUCCH-configMulticast1/pucch-ConfigurationListMulticast1中根据DCI的指示(所述HARQ-ACK信息有对应的调度DCI时)确定PUCCH资源;如果配置了mode 2(例如参数moreThanOneNackOnlyMode被配置时),UE根据PUCCH资源选择的方式传输不同的HARQ-ACK比特,具体的根据预定义表格(如下表1)确定HARQ-ACK的比特和PUCCH资源之间的映射关系,以确定反馈HARQ-ACK的PUCCH。其中,所述PUCCH由第二种反馈模式对应的PUCCH-config/PUCCH-configurationList配置,也即由PUCCH-configMulticast2/pucch-ConfigurationListMulticast2配置的PUCCH资源集(PUCCH resource set)中的资源列表(resourceList)确定。
表1 HARQ-ACK信息比特的值映射到PUCCH资源,用于第二种HARQ-ACK反馈模式
实施例三

1)若先处理所述第一PUCCH与所述CSI PUCCH之间的冲突(例如,如图5所示,在第一PUCCH、SR PUCCH和CSI PUCCH中,CSI PUCCH的起始时间早于SR PUCCH和第一PUCCH的起始时间,和/或,CSI PUCCH的符号数大于SR PUCCH和第一PUCCH的符号数,且CSI PUCCH与SR PUCCH的时域资源不重叠,或者UE按照上述确定参考PUCCH的方式在所述三个PUCCH中确定CSI PUCCH为参考PUCCH,且只有所述第一PUCCH与CSI PUCCH时域资源重叠),则:
将所述第一PUCCH承载的第二种反馈模式下的HARQ-ACK信息转换为第一种反馈 模式下的HARQ-ACK信息,并将转换后的HARQ-ACK信息和所述CSI PUCCH承载的CSI复用在第三PUCCH上;
如果所述第三PUCCH与所述SR PUCCH的时域资源重叠,则将所述第三PUCCH承载的HARQ-ACK信息和CSI以及所述SR PUCCH承载的SR信息复用在同一PUCCH上传输,或者,将所述SR PUCCH承载的SR信息丢弃,将所述第三PUCCH进行传输;

实施例十(关于所述多个上行信道的优先级和/或优先级索引不同的场景)
如图13A至图13C所示,所述多个上行信道包括第一PUCCH、SR PUCCH和另一上行信道,其中,所述另一上行信道包括PUCCH或PUSCH。
在图13A所示的场景中,第一PUCCH与SR PUCCH具有高优先级/高优先级索引(H),且二者时域资源重叠,另一上行信道(如PUCCH/PUSCH)具有低优先级/低优先级索引(L),这多个上行信道的时域资源重叠情况包括:第一PUCCH与SR PUCCH的时域资源重叠,SR PUCCH与另一上行信道的时域资源重叠,且第一PUCCH与另一上行信道(如PUCCH/PUSCH)的时域资源不重叠,在相关技术中,UE先处理相同优先级间的重叠,根据UE实现丢弃第一PUCCH或者丢弃SR PUCCH。如果UE丢弃第一PUCCH,则由于高优先级的SR PUCCH与低优先级的另一上行信道的时域资源重叠,UE取消低优先级的另一上行信道(如PUCCH/PUSCH)的传输,仅传输SR PUCCH。如果UE丢弃SR PUCCH,由于高优先级的第一PUCCH与低优先级的另一上行信道的时域资源不重叠,则UE可以分别传输第一PUCCH与另一上行信道。
为了避免网络侧设备进行盲检测,在图13A所示的场景下(例如,具有高优先级/优先级索引的第一PUCCH与具有高优先级/优先级索引SR PUCCH的时域资源重叠(所述SR为肯定的SR),且所述SR PUCCH与具有低优先级/优先级索引的PUCCH/PUSCH的时域资源重叠,且第一PUCCH与低优先级PUCCH/PUSCH的时域资源不重叠),网络侧设备或协议可以规范UE的行为,即第一方式可以包括:在处理第一PUCCH和SR PUCCH 时域资源重叠时,丢弃SR,传输第一PUCCH;或者,在处理第一PUCCH和SR PUCCH时域资源重叠时,丢弃第一PUCCH,传输SR PUCCH,而不是由UE实现确定丢弃第一PUCCH还是SR PUCCH。
在图13B所示的场景中,第一PUCCH、SR PUCCH和另一上行信道(如PUCCH/PUSCH)的时域资源重叠情况与图13A所示的场景相同,所不同的是第一PUCCH与SR PUCCH具有低优先级/优先级索引,所述另一上行信道(如PUCCH/PUSCH)具有高优先级/优先级索引。在该场景下,在相关技术中,UE先处理相同优先级间的重叠,根据UE实现丢弃第一PUCCH或者丢弃SR PUCCH;如果UE丢弃第一PUCCH,则由于低优先级的SR PUCCH与高优先级的所述另一上行信道的时域资源重叠,UE取消低优先级的SR PUCCH的传输,仅传输所述另一上行信道;如果UE丢弃SR PUCCH,由于低优先级的第一PUCCH与高优先级的所述另一上行信道的时域资源不重叠,UE分别传输第一PUCCH与所述另一上行信道。此时,终端侧存在不必要的丢弃(如不传输第一PUCCH),而网络侧设备需要进行盲检测。
为了避免上述不必要的丢弃以及网络侧设备的盲检测,在图13B所示的场景下(例如,具有低优先级/优先级索引的第一PUCCH与具有低优先级/优先级索引的SR PUCCH的时域资源重叠(所述SR为肯定的SR),第一PUCCH与SR PUCCH中有一个PUCCH与具有高优先级/优先级索引的所述另一上行信道(如PUCCH/PUSCH)的时域资源重叠,则网络侧设备或协议可以规定(即第一方式可以包括):UE在处理第一PUCCH与SR PUCCH的时域资源重叠时,丢弃与具有高优先级/优先级索引的所述另一上行信道的时域资源重叠的信道承载的信息,传输与具有高优先级/优先级索引的所述另一上行信道的时域资源不重叠的信道。
在图13C所示的场景中,第一PUCCH与SR PUCCH具有低优先级/低优先级索引(L),且二者时域资源重叠,另一上行信道(如PUCCH/PUSCH)具有高优先级/高优先级索引(H),这多个上行信道的时域资源重叠情况包括:第一PUCCH与SR PUCCH的时域资源重叠,第一PUCCH与所述另一上行信道的时域资源重叠,且SR PUCCH与另一上行信道(如PUCCH/PUSCH)的时域资源不重叠,在相关技术中,UE先处理相同优先级间的重叠,根据UE实现丢弃第一PUCCH或者丢弃SR PUCCH;如果UE丢弃SR PUCCH,则由于低优先级的第一PUCCH与高优先级的所述另一上行信道的时域资源重叠,UE取消低优先级的第一PUCCH的传输,仅传输所述另一上行信道;如果UE丢弃第一PUCCH,由于低优先级的SR PUCCH与高优先级的所述另一上行信道的时域资源不重叠,UE分别传输SR PUCCH与所述另一上行信道。此时,终端侧存在不必要的丢弃(如不传输SR PUCCH),而网络侧设备需要进行盲检测。
为了避免上述不必要的丢弃以及网络侧设备的盲检测,在图13C所示的场景下(例如,具有低优先级/优先级索引的第一PUCCH与具有低优先级/优先级索引的SR PUCCH的时域资源重叠(所述SR为肯定的SR),第一PUCCH与SR PUCCH中有一个PUCCH 与具有高优先级/优先级索引的所述另一上行信道(如PUCCH/PUSCH)的时域资源重叠,则网络侧设备或协议可以规定(即第一方式可以包括):UE在处理第一PUCCH与SR PUCCH的时域资源重叠时,丢弃与具有高优先级/优先级索引的所述另一上行信道的时域资源重叠的信道承载的信息,传输与具有高优先级/优先级索引的所述另一上行信道的时域资源不重叠的信道。
上面通过十个实施例对步骤201中的所述多个上行信道的时域资源发生重叠的不同情况进行了说明,需要说明的是,步骤201中的所述多个上行信道的时域资源发生重叠的情况可以不局限于上述十个实施例所述的情况,还可以是其他情况,本申请实施例不再列举。
还需要说明的是,在所述多个上行信道包括PUCCH和PUSCH的情况下,可先处理PUCCH之间的重叠,再处理PUCCH与PUSCH之间的重叠。例如,在上述实施例九中,在处理PUCCH与PUCCH之间的重叠时,UE分别传输第一PUCCH与SR PUCCH,在处理PUCCH与PUSCH之间的重叠时,由于第一PUCCH与PUSCH重叠,则UE将NACK only转换为ACK/NACK信息并复用在PUSCH上传输,并单独传输SR PUCCH。
通过上述十个实施例可以看出,针对同一重叠情况,如果采用不同的第一方式对所述多个上行信道的传输进行处理,可以得到不同的处理结果。对于网络侧设备来说,UE的行为是不确定的,网络侧设备需要通过盲检测来判断UE是如何传输所述多个上行信道的。
为了避免网络侧设备的盲检测,网络侧设备或协议可以规定UE在不同重叠情况下的具体行为,也即网络侧设备或协议可以规定UE在不同重叠情况下具体采用的第一方式,或者说,在所述多个上行信道的不同重叠情况下,可由网络侧设备配置或协议规定UE采用的第一方式。例如:

2)在上述实施例二所述的重叠情况(第一PUCCH与同时承载有SR信息和CSI的第二PUCCH的时域资源重叠)下,网络侧设备配置或协议规定所述第一方式为:将所述第一PUCCH上承载的第二种反馈模式下的HARQ-ACK信息转换为第一种反馈模式下的HARQ-ACK信息,并将转换后的HARQ-ACK信息和所述第二PUCCH上承载的CSI和SR信息复用在同一PUCCH上传输。

以上对本申请实施例提供的一种上行信道的传输方法进行了介绍。
需要说明的是,本申请实施例提供的上行信道的传输方法,执行主体可以为上行信道的传输装置。本申请实施例中以上行信道的传输装置执行上行信道的传输方法为例,说明本申请实施例提供的上行信道的传输装置。
下面结合附图对本申请实施例提供的一种上行信道的传输装置进行说明。由于本申请实施例提供的一种上行信道的传输装置与本申请实施例提供的一种上行信道的传输方法对应,因此对本申请实施例提供的一种上行信道的传输装置描述的较为简要,详细内容可参考上文方法实施例部分的介绍。
如图14所示,本申请的一个实施例提供了一种上行信道的传输装置1400,该装置1400可包括传输处理模块1401。
传输处理模块1401,用于在待传输的多个上行信道的时域资源发生重叠的情况下,终端按照第一方式对所述多个上行信道的传输进行处理。
其中,所述多个上行信道包括第一PUCCH,且所述多个上行信道还包括第二PUCCH和PUSCH中的至少一项,所述第一PUCCH上承载有第二种反馈模式下的混合自动重传请求应答HARQ-ACK信息,所述第二种反馈模式为仅反馈否定应答HARQ-NACK信息的反馈模式,所述第二PUCCH上承载有调度请求(Scheduling Request,SR)信息和信道状态信息(Channel State Information,CSI)中的至少一项。也就是说,本申请实施例述及的上行信道传输装置1400,针对的是HARQ NACK only反馈模式(所述第二种反馈模式)下,需要传输的多个上行信道在时域资源上重叠时,如何解决这多个上行信道之间的冲突的这一应用场景。
需要说明的是,所述多个上行信道的时域资源发生重叠包括所述多个上行信道中的部分或全部信道之间的部分或全部时域资源重叠,详见上文中的实施例一至实施例十。
其中,所述第一方式包括但不限于下述至少一项:
将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃;
将所述多个上行信道中时域资源重叠的至少两个上行信道复用至同一上行信道;
将所述多个上行信道中时域资源未重叠的信道单独传输。
可以理解,通过丢弃和复用等方式可很好地解决所述多个上行信道因时域资源发生重叠导致的冲突问题。
在一个例子中,所述多个上行信道可以是同一PUCCH重叠组内的多个信道。当然,所述多个上行信道也可以不属于同一PUCCH重叠组。
其中,确定PUCCH重叠组的过程,可包括:先在多个候选PUCCH中选择一个参考PUCCH;将所述多个候选PUCCH中所有与所述参考PUCCH重叠的PUCCH和所述参考PUCCH,确定为一个PUCCH重叠组。
无论所述多个上行信道是否属于同一PUCCH重叠组,若所述多个上行信道包括所述第二PUCCH,则所述第二PUCCH可包括下述两种情况:
(1)所述第二PUCCH包括SR PUCCH和CSI PUCCH,其中,所述SR PUCCH是承载SR信息的PUCCH,所述CSI PUCCH是承载CSI的PUCCH;
(2)所述第二PUCCH包括同时承载SR信息和CSI的PUCCH。
其中,所述SR信息包括肯定(positive)SR信息和否定(negative)SR信息中的至少一项。
可选的,若所述多个上行信道包括所述第二PUCCH,则所述第二PUCCH的数量可以是一个,也可以是多个。
可选的,若所述多个上行信道包括所述PUSCH,则所述PUSCH的数量可以是一个,也可以是多个。
可选的,所述多个上行信道中包括的所述第一PUCCH、所述第二PUCCH和所述PUSCH具有相同或不同的优先级和/或优先级索引。其中,各上行信道的优先级可以是网络侧设备指示或配置的,一个上行信道的优先级可包括高、低两个等级,高优先级可表示为:priority index=1,低优先级可表示为:priority index=0。
可选的,所述多个上行信道中包括的所述第一PUCCH、所述第二PUCCH和所述PUSCH具有相同的优先级和/或优先级索引。
进一步的,在按照第一方式对所述多个上行信道的传输进行处理时,若所述第一方式包括将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃,则所述将所述多个上行信道中时域资源重叠的至少一个上行信道丢弃,包括:将所述多个上行信道中优先级低的至少一个上行信道丢弃;若所述第一方式包括将所述多个上行信道中时域资源重叠的至少两个上行信道复用至同一上行信道,则所述将所述多个上行信道中时域资源重叠的至少两个上行信道复用至同一上行信道,包括:将所述多个上行信道中时域资源重叠且优先级相同的至少两个上行信道复用至同一上行信道。
关于所述多个上行信道的重叠情况,以及这些重叠情况下的第一方式请参见上文中的 实施例一至实施例九,此处不再赘述。
需要说明的是,针对同一重叠情况,如果采用不同的第一方式对所述多个上行信道的传输进行处理,可以得到不同的处理结果。对于网络侧设备来说,UE的行为是不确定的,网络侧设备需要通过盲检测来判断UE是如何传输所述多个上行信道的。
为了避免网络侧设备的盲检测,网络侧设备或协议可以规定UE在不同重叠情况下的具体行为,也即即网络侧设备或协议可以规定UE在不同重叠情况下具体采用的第一方式,或者说,在所述多个上行信道的不同重叠情况下,可由网络侧设备配置或协议规定UE采用的第一方式。
需要说明的是,图14所示的装置能够实现图2所示的方法,并能取得相同的技术效果,因此描述的较为简单,相关之处可参考上文对图2所示的实施例的描述。
需要说明的是,本申请实施例中的上行信道的传输装置可以是电子设备,例如具有操作系统的电子设备,也可以是电子设备中的部件,例如集成电路或芯片。该电子设备可以是终端,也可以为除终端之外的其他设备。示例性的,终端可以包括但不限于上述所列举的终端11的类型,其他设备可以为服务器、网络附属存储器(Network Attached Storage,NAS)等,本申请实施例不作具体限定。
