具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、未来的5G系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如设备到设备(Device to Device,D2D)通信、机器到机器(Machine to Machine,M2M)通信、机器类型通信(Machine Type Communication,MTC)、以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可应用于这些通信系统。
本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation,CA)场景、双连接(Dual Connectivity,DC)场景、独立(Standalone,SA)布网场景等。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。
可选地,网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。终端设备120可以是移动的或固定的。可选地,终端设备120可以指用户设备、接入终端、 用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例对此并不限定。其中,可选地,终端设备120之间也可以进行终端直连(Device to Device,D2D)通信。
网络设备110可以为小区提供服务,终端设备120通过该小区使用的传输资源,例如频域资源,或者说频谱资源,与网络设备110进行通信。该小区可以是网络设备110对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备,但本申请并不限于此。该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备。此外,该无线通信系统100还可以包括网络控制器、移动性管理实体等其他网络实体。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱通常被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存,一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如,在一些地区,通信设备遵循"先听后说(Listen Before Talk,LBT)"原则,即通信设备在免授权频谱的信道上进行信号发送前,需要先进行信道侦听,只有当信道侦听结果为信道空闲时,该通信设备才能进行信号发送;如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙,该通信设备不能进行信号发送。为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time,MCOT)。
在LBT机制中,发送端一旦抢占信道成功,应该尽可能占用连续的资源进行数据传输。接收端应该尽可能地将确认(Acknowledgement,ACK)/否定确认(Negative Acknowledgement,NACK)复用传输,以占用少量的时频资源,避免不必要的LBT过程。
目前,支持动态确定HARQ反馈时序(HARQ-timing)。终端设备确定预配置的HARQ反馈时序集合,例如{k1,k2,……,kn},网络设备通过DCI中的HARQ反馈时序指示信息,向终端设备指示该集合中的一个数值ki,1≤ki≤n。如果对下行控制信息(Download Control Information,DCI)调度的PDSCH在时隙n中传输,那么该PDSCH的反馈信息在时隙n+ki中传输。其中,HARQ反馈时序集合最多例如可以包括8个取值。对于DCI格式1_0(DCI format 1_0),HARQ反馈时序集合可以由协议约定,对于DCI format 1_1,该集合可以由网络设备配置。
另外,在基于非授权频段的NR系统(NR-based Access to Unlicensed Spectrum)中, 允许HARQ反馈时序为一个特殊取值,该特殊取值表示该DCI调度的PDSCH的ACK/NACK的传输时间和传输资源暂时无法确定。网络设备后续可以通过其他指示信息,触发终端设备发送该PDSCH的ACK/NACK。例如,可以通过专用的下行控制信令、用于调度PSCH的下行控制信令、用于调度PDSCH的下行控制信令等,触发终端设备传输之前的该PDSCH的反馈信息。并且,为支持上述的HARQ反馈方式,允许终端设备基于PDSCH组进行反馈。网络设备通过DCI指示PDSCH组的信息,从而触发终端设备发送某一组PDSCH的反馈信息,该PDSCH组内的所有PDSCH的反馈信息都需要被发送。
但是,这就引入了新的问题。一方面,HARQ反馈时序指示信息中指示的数值ki不可更改,引入HARQ反馈时序的特殊取值后,即无效取值,如果同一个PDSCH组中的一部分PDSCH对应的HARQ反馈时序的取值为有效,而另一部分PDSCH对应的HARQ反馈时序的取值为无效,这时,应该如何对该PDSCH组的反馈信息进行传输成为需要考虑的问题。另一方面,由于NR-U系统中,传输资源需要依赖LBT,发送端一旦抢占信道成功,应该尽可能地占用连续的资源进行数据传输,但是目前的反馈方式会由于反馈信息的频繁发送导致下行资源不连续,从而降低系统效率。
为此,本申请实施例提供一种信息反馈的方法,能够实现信道组的反馈信息的有效传输。
图2是本申请实施例的信息反馈的方法的流程交互图。该方法可以由网络设备和终端设备执行。所述网络设备例如可以为图1中所示的网络设备110,所述终端设备例如可以为图1中所示的终端设备120。如图2所示,该方法200包括以下步骤中的部分或全部。
在210中,网络设备发送第一DCI。
在220中,终端设备接收所述第一DCI。
在230中,网络设备在所述第一DCI之后,发送第二DCI。
在240中,终端设备在所述第一DCI之后,接收所述第二DCI。
其中,所述第一DCI对应的下行信道和所述第二DCI对应的下行信道属于相同的信道组,所述第一DCI和所述第二DCI中包括时间信息域,所述时间信息域指示用于发送所述信道组的反馈信息的时间,所述第一DCI中的所述时间信息域与所述第二DCI中的所述时间信息域指示的时间不同。
在250中,终端设备根据所述第二DCI,确定用于发送所述信道组的反馈信息的时间信息。
在260中,网络设备根据所述第二DCI,确定用于接收所述信道组的反馈信息的时间信息。
本申请实施例中,网络设备先后向终端设备发送了第一DCI和第二DCI,由于第一DCI中的时间信息域与第二DCI中的时间信息域指示的用于发送该信道组的反馈信息的时间可能不同,这时,终端设备基于第二DCI,确定用于发送该信道组的反馈信息的时间信息。
换句话说,当先后传输的第一DCI和第二DCI对应的下行信道属于相同的信道组时,且两个DCI中的时间信息域指示的时间不同时,可以基于第二DCI确定传输所述信道组的反馈信息的时间信息,从而基于这些时间信息,实现对该信道组的反馈信息的有效传输。由于允许通过在后的第二DCI对在前的第一DCI中的时间信息域指示的时间进行更新, 因此实现了更加灵活的反馈。
所述信道组的反馈信息包括所述信道组中的下行信道对应的ACK信息或者NACK信息。
应理解,用于发送所述信道组的反馈信息的所述时间信息,不仅包括终端设备发送该信道组的反馈信息的时间,即终端设备应该在哪些时间单元上发送该反馈信息;也包括终端设备不需要发送该信道组的反馈信息的时间,即不需要在哪些时间上发送该信道组的反馈信息。
另外,本申请实施例中,所述第一DCI对应的下行信道例如包括所述第一DCI调度的下行信道或传输所述第一DCI的下行信道,所述第二DCI对应的下行信道例如包括所述第二DCI调度的下行信道或传输所述第二DCI的下行信道。
也就是说,终端设备可以对第一DCI和第二DCI所在的物理上行控制信道(Physical Uplink Control Channel,PUCCH)进行反馈。终端设备向网络设备发送第一DCI所在的PUCCH和第二DCI所在的PUCCH的反馈信息。其中,第一DCI所在的PUCCH和第二DCI所在的PUCCH属于相同的PUCCH组。
或者,终端设备也可以对第一DCI和第二DCI调度的PDSCH进行反馈。终端设备向网络设备发送第一DCI调度的PDSCH和第二DCI调度的PDSCH的反馈信息。其中,第一DCI调度的PDSCH和第二DCI调度的PDSCH属于相同的PDSCH组。
对于第一DCI和第二DCI对应的下行信道所属的信道组的信息,网络设备可以通过DCI指示给终端设备。例如,第一DCI和第二DCI中可以包括信道组信息域,或者称PDSCH HARQ反馈时序指示(PDSCH-to-HARQ_feedback timing indicator)信息域,其中,第一DCI中的所述信道组信息域指示第一DCI对应的下行信道所属的信道组,第二DCI中的所述信道组信息域指示第二DCI对应的下行信道所属的信道组。这里,第一DCI和第二DCI中的信道组信息域指示相同的信道组。
第一DCI中的时间信息域和第二DCI中的时间信息域可以指示有效的时间,也可以指示无效的时间。例如,第一DCI中的时间信息域指示第一时间单元,则表示终端设备可以在该第一时间单元上发送该信道组的反馈信息;第一DCI中的时间信息域指示的时间为无效,则表示用于发送该信道组的反馈信息的时间暂未确定,当前还没有合适的时间和资源用来发送该反馈信息。又例如,第二DCI中的时间信息域指示第二时间单元,则表示终端设备可以在该第二时间单元上发送该信道组的反馈信息;第二DCI中的时间信息域指示的时间为无效,则表示用于发送该信道组的反馈信息的时间暂未确定,当前还没有合适的时间和资源用来发送该反馈信息。其中,该时间信息域的内容为特定值时,可以表示该时间信息域指示的时间为无效。
以下,分别对这几种情况进行描述。
首先,描述所述第二DCI中的所述时间信息域指示第二时间单元时,终端设备如何对反馈信息进行处理。即,所述第二DCI中的所述时间信息域指示时间为有效。
可选地,在250中,终端设备根据所述第二DCI,确定用于发送所述信道组的反馈信息的时间信息,包括:终端设备确定在所述第二时间单元上发送所述信道组的反馈信息。
其中,所述第二时间单元上发送的所述信道组的反馈信息中包括所述第一DCI和所述第二DCI对应的下行信道的反馈信息。
相应地,在260中,网络设备根据所述第二DCI,确定用于接收所述信道组的反馈信息的时间信息,包括:网络设备确定在所述第二时间单元上接收所述信道组的反馈信息。
其中,所述第二时间单元上接收的所述信道组的反馈信息中包括所述第一DCI和所述第二DCI对应的下行信道的反馈信息。
该实施例中,所述第二DCI中的所述时间信息域指示的时间为有效,因此终端设备可以根据第二DCI中的时间信息域指示的时间发送该信道组的反馈信息,即,在第二时间单元上发送该信道组的反馈信息。
这时,无论第一DCI中的时间信息域指示的时间为有效还是无效,终端设备均可以根据第二DCI中的时间信息域指示的第二时间单元,发送该信道组的反馈信息。
例如,如图3所示,终端设备接收第一DCI,并在第一DCI之后接收第二DCI,其中,第一DCI中的时间信息域指示的时间为无效,第二DCI中的时间信息域指示第二时间单元。由于第二DCI中的时间信息域指示第二时间单元,因此终端设备在第二时间单元上发送PUCCH 2,网络设备在第二时间单元上接收PUCCH 2,其中,PUCCH 2中包括该信道组的反馈信息。PUCCH 2中承载的该信道组的反馈信息中包括第一DCI对应的下行信道的反馈信息和第二DCI对应的下行信道的反馈信息。另外,如果在第一DCI之前还存在属于相同信道组的下行信道,则PUCCH 2中发送的该信道组的反馈信息中也包括这些下行信道的反馈信息。
所述第二DCI中的所述时间信息域指示的时间为有效时,如果第一DCI中的时间信息域指示的时间也为有效。这时,可选地,终端设备还可以判断,是否仍需要在第一DCI中的时间信息域指示的第一时间单元上发送该信道组的反馈信息。
可选地,在250中,终端设备根据所述第二DCI,确定用于发送所述信道组的反馈信息的时间信息,还包括:终端设备根据用于接收所述第二DCI的时间资源,与所述第一时间单元之间的时间间隔,确定是否在所述第一时间单元上发送所述信道组的反馈信息。
其中,所述时间资源位于所述第一时间单元之前。即终端设备在第一时间单元到来之前接收到所述第二DCI。
相应地,在260中,网络设备根据所述第二DCI,确定用于接收所述信道组的反馈信息的时间信息,还包括:网络设备根据所述时间资源与所述第一时间单元之间的时间间隔,确定是否在所述第一时间单元上接收所述信道组的反馈信息。
以终端设备为例,由于第一DCI和第二DCI中的时间信息域指示的时间均为有效,那么终端设备可以在第二DCI的时间信息域指示的第二时间单元上发送该信道组的反馈信息。并且,进一步地,由于存在第一时间单元,终端设备还需要判断是否需要暂停第一单元内的反馈信息的传输。终端设备可以根据用于传输第二DCI的时间资源与第一时间单元之间的时间间隔,确定是否在第一时间单元上发送所述信道组的反馈信息。
所述时间间隔例如可以指所述时间资源的结束时刻和所述第一时间单元的起始时刻之间的时间长度。
例如,若所述时间间隔小于预设值,终端设备确定在所述第一时间单元上发送所述信道组的反馈信息。相应地,网络设备确定在所述第一时间单元上接收所述信道组的反馈信息。其中,所述第一时间单元上发送的所述信道组的反馈信息中包括所述第一DCI对应的下行信道的反馈信息。
又例如,若所述时间间隔大于或等于所述预设值,终端设备确定不在所述第一时间单元上发送所述信道组的反馈信息。相应地,网络设备确定不在所述第一时间单元上接收所述信道组的反馈信息。
其中,该预设值可以是网络设备配置的,或者是协议约定的。
举例来说,如图4(a)和图4(b)所示,终端设备接收第一DCI,并在第一DCI之后接收第二DCI,其中,第一DCI中的时间信息域指示第一时间单元,第二DCI中的所述时间信息域指示第二时间单元。第一DCI的信道组信息域和第二DCI中的信道组信息域中指示相同的信道组1。终端设备可以在第二时间单元上发送PUCCH 2,网络设备在第二时间单元上接收PUCCH 2,其中,PUCCH 2中包括该信道组的反馈信息。PUCCH 2中承载的该信道组的反馈信息中包括第一DCI对应的下行信道的反馈信息和第二DCI对应的下行信道的反馈信息。另外,如果在第一DCI之前还存在属于相同信道组的下行信道,则PUCCH 2中发送的该信道组的反馈信息中也包括这些下行信道的反馈信息。
进一步地,终端设备根据用于传输第二DCI的时间资源,与第一DCI中的时间信息域指示的第一时间单元之间的时间间隔,判断是否停止第一时间单元内的反馈信息的传输。如图4(a)所示,第二DCI与第一时间单元之间的时间间隔为T1,T1大于该预设值,则终端设备确定不需要在第一时间单元上发送PUCCH 1。如图4(b)所示,第二DCI与第一时间单元之间的时间间隔为T2,若T2小于该预设值,终端设备确定仍需要在第一时间单元上发送PUCCH 1,其中,PUCCH 1中承载的该信道组的反馈信息。
所述预设值例如可以为终端设备取消在第一时间单元上发送反馈信息所需的处理时间,其中包括终端设备对DCI进行解调译码所需的时间,以及停止PUCCH传输所需的时间。
结合图4(a)和图4(b)进行说明。如图4(a)所示,第二DCI与第一时间单元之间的时间间隔为T1,T1大于该预设值。也就是说,在T1时长内,终端设备有足够的时间对第二DCI进行解调译码以获取第二DCI中的时间信息域指示的第二时间单元的位置,并取消PUCCH 1的传输。这时,终端设备在第二时间单元上发送该信道组的反馈信,无需在第一时间单元上发送该信道组的反馈信息。从而避免重复发送反馈信息导致的下行资源不连续,避免不必要的LBT。
如图4(b)所示,第二DCI与第一时间单元之间的时间间隔为T2,T2小于该预设值。也就是说,在T2时长内,终端设备无法完成对第二DCI的解调译码以及对PUCCH 1的取消。这时,为了让网络设备尽快获得反馈信息,终端设备可以在第一时间单元上发送该信道组的反馈信息。这时,第一时间单元上发送的PUCCH 1中包括第一DCI对应的下行信道的反馈信息,不包括第二DCI对应的下行信道的反馈信息。另外,如果在第一DCI之前还存在属于相同信道组的下行信道,则PUCCH 1中发送的该信道组的反馈信息中也包括这些下行信道的反馈信息。
应理解,如果终端设备确定在第二时间单元上发送所述信道组的反馈信息,则所述信道组的反馈信息中除了包括第一DCI和第二DCI对应的下行信道的反馈信息,还可以包括位于所述第一DCI之前且属于所述信道组的其他下行信道的反馈信息。如果终端设备确定在第一时间单元上发送所述信道组的反馈信息,则所述信道组的反馈信息中除了包括第一DCI对应的下行信道的反馈信息,还可以包括位于所述第一DCI之前且属于所述信道 组的其他下行信道的反馈信息。
也就是说,终端设备可以在不同的时间单元上多次发送所述信道组的反馈信息,但是每次发送的所述信道组的反馈信息中,可以不断地增加属于相同信道组的下行信道的反馈信息。例如,第一DCI的时间信息指示域指示的第一时间单元,可以用于发送第一DCI以及第一DCI之前的DCI对应的下行信道的反馈信息。第二DCI的时间信息指示域指示的第二时间单元,可以用于发送第二DCI以及第二DCI之前的DCI对应的下行信道的反馈信息。
接下来,描述所述第一DCI中的所述时间信息域指示第一时间单元时,终端设备如何对反馈信息进行处理。即,所述第一DCI中的所述时间信息域指示时间为有效。
可选地,在250中,终端设备根据所述第二DCI,确定用于发送所述信道组的反馈信息的时间信息,包括:终端设备根据用于接收所述第二DCI的时间资源,与所述第一时间单元之间的时间间隔,确定是否在所述第一时间单元上发送所述信道组的反馈信息。
其中,所述时间资源位于所述第一时间单元之前。即终端设备在第一时间单元到来之前接收到所述第二DCI。
相应地,在260中,网络设备根据所述第二DCI,确定用于接收所述信道组的反馈信息的时间信息,包括:网络设备根据用于接收所述第二DCI的时间资源,与所述第一时间单元之间的时间间隔,确定是否在所述第一时间单元上接收所述信道组的反馈信息。
以终端设备为例,由于第一DCI中的时间信息域指示的时间为有效,并且终端设备在第一时间单元之前接收到了第二DCI,那么终端设备需要判断是否要暂停第一单元内的反馈信息的传输。终端设备可以根据用于传输第二DCI的时间资源与第一时间单元之间的时间间隔,确定是否在第一时间单元上发送所述信道组的反馈信息。
例如,若所述时间间隔小于预设值,终端设备确定在所述第一时间单元上发送所述信道组的反馈信息。相应地,网络设备确定在所述第一时间单元上接收所述信道组的反馈信息。其中,所述第一时间单元上发送的所述信道组的反馈信息中包括所述第一DCI对应的下行信道的反馈信息。
又例如,若所述时间间隔大于或等于所述预设值,终端设备确定不在所述第一时间单元上发送所述信道组的反馈信息。相应地,网络设备确定不在所述第一时间单元上接收所述信道组的反馈信息。
其中,该预设值可以是网络设备配置的,或者是协议约定的。
举例来说,如图5(a)和图5(b)所示,终端设备接收第一DCI且第一DCI中的时间信息域指示第一时间单元,但是在第一时间单元之前终端设备接收到第二DCI。并且,第二DCI的信道组信息域和第一DCI中的信道组信息域中指示相同的信道组1。终端设备根据第二DCI与所述第一时间单元之间的时间间隔,判断是否需要在第一时间单元上发送该信道组的反馈信息。如图4(a)所示,第二DCI与第一时间单元之间的时间间隔为T1,T1大于该预设值,则终端设备确定不在第一时间单元上发送PUCCH 1。如图4(b)所示,第二DCI与第一时间单元之间的时间间隔为T2,若T2小于该预设值,则终端设备确定仍需要在第一时间单元上发送PUCCH 1,其中,PUCCH 1中承载的该信道组的反馈信息。
所述预设值例如可以为终端设备取消在第一时间单元上发送反馈信息所需的处理时间,其中包括终端设备对DCI进行解调译码所需的时间,以及停止PUCCH传输所需的时 间。
结合图5(a)和图5(b)进行说明。如图5(a)所示,第二DCI与第一时间单元之间的时间间隔为T1,T1大于该预设值。也就是说,在T1时长内,终端设备有足够的时间对第二DCI进行解调译码以获取第二DCI中的时间信息域中的内容,并取消PUCCH 1的传输。这时,终端设备无需在第一时间单元上发送该信道组的反馈信息,并根据第二DCI对反馈信息进行处理。从而避免重复发送反馈信息导致的下行资源不连续,避免不必要的LBT。
如图5(b)所示,第二DCI与第一时间单元之间的时间间隔为T2,T2小于该预设值。也就是说,在T2时长内,终端设备无法完成对第二DCI的解调译码以及对PUCCH 1的取消。这时,为了让网络设备尽快获得反馈信息,终端设备可以在第一时间单元上发送该信道组的反馈信息。这时,第一时间单元上发送的PUCCH 1中包括第一DCI对应的下行信道的反馈信息,不包括第二DCI对应的下行信道的反馈信息。另外,所述信道组的反馈信息中除了包括第一DCI对应的下行信道的反馈信息,还可以包括位于所述第一DCI之前且属于所述信道组的其他下行信道的反馈信息。
这时,无论第二DCI中的时间信息域指示的时间为有效还是无效,终端设备均可以根据第二DCI与第一时间单元之间的时间间隔,确定是否在第一时间单元上发送该信道组的反馈信息。
例如图5(a)和图5(b)所示,第二DCI中的时间信息域指示的时间可以为无效。又例如,图4(a)和图4(b)所示,第二DCI中的时间信息域指示的时间可以为有效。
举例来说,在本申请实施例的可能的几种实现方式中,第一DCI和第二DCI中的时间信息域指示的时间均为有效时,终端设备可以在第二DCI中的时间信息域指示的第二时间单元上发送该信道组的反馈信息,并进一步地根据第一DCI中的时间信息域指示的第一时间单元与第二DCI之间的时间间隔,确定是否仍需要在第一时间单元上发送该信道组的反馈信息;第一DCI中的时间信息域指示的时间为有效,第二DCI中的时间信息域指示的时间为无效时,终端设备可以根据第一时间单元与第二DCI之间的时间间隔,确定是否在第一时间单元上发送该信道组的反馈信息;第一DCI中的时间信息域指示的时间为无效,第二DCI中的时间信息域指示的时间为有效时,终端设备可以在第二时间单元上发送该信道组的反馈信息;第一DCI和第二DCI中的时间信息域指示的时间均为无效时,终端设备暂时不发送该信道组的反馈信息。
可见,本申请实施例中,终端设备接收到的两个DCI中的信道组信息域指示相同的信道组,且两个DCI中的时间信息域指示的时间不同时,终端设备可以根据在后的第二DCI中的时间信息域中的内容,确定用于发送该信道组的反馈信息的时间的相关信。例如,根据第二DCI确定传输该信道组的反馈信息的时间,并根据第二DCI确定在前的第一DCI中的时间信息域指示的时间内是否仍需要发送该信道组的反馈信息。一方面,这种信息反馈的方式允许通过第二DCI对在第一DCI中的时间信息域指示的时间进行更新,使得反馈时间可以更改,实现了更加灵活的反馈,增加了调度的灵活性;另一方面,由于终端设备无需在所有DCI中的时间信息域指示的时间上都进行反馈,减少了终端设备发送反馈信息的次数,减少了NR-U系统中下行资源的不连续,提高了系统效率。
本申请实施例中的各个示例均以终端设备为例,描述终端设备如何确定用于发送该信 道组的反馈信息的时间信息。网络设备如何确定用于接受该信道组的反馈信息的时间信息,可以参考前述关于终端设备确定该时间信息的的相关描述,为了简洁,这里不再赘述。
需要说明的是,在不冲突的前提下,本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合,组合之后得到的技术方案也应落入本申请的保护范围。
在本申请的各种实施例中,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。
