Description

一种数据传输方法及相关设备 技术领域
本申请涉及通信技术领域,尤其涉及一种数据传输方法及相关设备。
背景技术
第五代移动通信(5-Generation,5G)新无线(new radio,NR)引入了超高可靠低时延(Ultra-reliable low latency,URLLC)业务,该URLLC业务的特征是在极端的时延内(例如,1ms)实现超高可靠性的传输。第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)第15版本(Release 15,Rel-15)中规定一个下行链路(Down Link,DL)混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程的肯定确认/否定确认(Acknowledgement/Negative Acknowledgement,ACK/NACK)未发送前,该HARQ进程编号不能被重用。当URLLC的某个HARQ进程采用无反馈下行传输时,按照现有的规定,则该进程将无法再被使用,从而降低了实际支持的最大HARQ进程的数量,影响数据传输速率。另外,当多个上行信道在时域上重叠时,如果通过基站发送的指示信令确定各信道的优先级,会增加指示信令的开销。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
请参见图1,图1是本申请实施例提供的一种数据传输系统的架构示意图,该数据传输系统包括用户设备(User Equipment,UE)和网络设备。用户设备可以是终端、用户单元、用户站、移动站、移动台、远程站、接入点、远程终端、接入终端、用户终端、用户代理、用户装置或计算机设备等。网络设备是指与终端进行通信的设备,例如,可以为基站、接入点、节点、演进型节点(Environment Bureau,eNB)或5G基站(Next generation base station,gNB)等。NR Rel-15系统规定,UE接收下行控制信息(Downlink control information,DCI)格式1_0或DCI格式1_1后,接收该DCI调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)(即动态调度PDSCH),该PDSCH对应的HARQ进程编号由DCI指示。当UE未发送该PDSCH对应的ACK/NACK信息之前,UE不期待基站调度一个新的PDSCH的HARQ进程编号与前一个PDSCH的HARQ进程编号相同,即在某一个DL HARQ进程传输之后、且ACK/NACK信息未发送之前,基站不能重用该HARQ进程编号进行数据传输。如图2所示,图2是本申请实施例提供的一种数据传输的示意图,DCI1调度PDSCH1,PDSCH1采用HARQ 进程编号X,在UE向基站发送PDSCH1对应的ACK/NACK信息之前,如果基站又调度了PDSCH2,则PDSCH2对应的HARQ也采用HARQ进程编号X是不被允许的。
其中,在DCI调度PDSCH的同时,可以通过DCI中的PDSCH反馈时序(PDSCH-to-HARQ_feedback timing indicator)信息域指示该PDSCH对应的ACK/NACK信息的传输时间。具体的,用户设备首先确定预配置的HARQ反馈时序集合。其中,针对不同的应用场景,HARQ反馈时序集合有两种确定方式:协议约定和高层信令配置。该HARQ反馈时序集合中最多包括8个索引值。用户设备接收到DCI后,从PDSCH-to-HARQ_feedback timing indicator信息域获取一个索引值,通过该索引值确定预配置HARQ反馈时序集合中的一个元素k,如果DCI调度的PDSCH在时隙n中传输,则PDSCH对应的ACK/NACK信息在slot n+k中传输。
对于URLLC业务,为了兼顾低时延和高可靠性,基站在调度URLLC业务时,可以分配更多的物理资源或使用更可靠的传输方案,从而保证单次传输就可以满足需求。在此情况下用户设备进行ACK/NACK信息的反馈已经没有实际意义。另外,当一个HARQ进程的实际传输时间点已经很接近最大时延,再次重传必定会不满足时延需求时,用户设备向基站反馈ACK/NACK信息也没有实际意义。如图3所示,图3是本申请实施例提供的一种数据传输的示意图。其中T表示最大时延。对于URLLC业务的下行传输,应该支持无反馈传输。一种实现方式是在调度PDSCH的DCI中通过PDSCH-to-HARQ_feedback timing indicator信息域指示一个特定k值(例如,无意义、无穷大等),表示该DCI调度的PDSCH无对应的ACK/NACK信息反馈。当该信息域指示的k为其他值时,用户设备根据该k值进行ACK/NACK信息的反馈。
如图4所示,图4是本申请实施例提供的一种信道复用的示意图。在Rel-15中,当多个上行信道在时域上重叠,若所述多个上行信道中的最早起始时间距离多个上行信道对应的多个下行信道中的最晚截止时间满足多个上行信道中需要的最大处理时延需求,则多个上行信道承载的信息可以复用于一个信道内传输。否则,用户设备的行为不做规定,实际中就是基站不应该这种调度。
这样显然不能满足Rel-16URLLC的时延需求。即当发生碰撞的多个信道中有增强移动宽带(Enhance Mobile Broadband,eMBB)业务和URLLC业务的信道,按照现有方法需要满足eMBB业务的处理时延,才能将URLLC业务和eMBB业务的上行信息进行复用传输到基站,而eMBB业务的处理时延显著大于URLLC业务的时延需求。例如,如图5所示,图5是本申请实施例提供的另一种信道复用的示意图。eMBB业务的PDSCH已经传输完成,PDSCH对应的物理上行控制信道(Physical Uplink Control Channel,PUCCH)已经预先分配,此时URLLC业务的PDSCH在eMBB业务的PDSCH之后到达,由于不能满足eMBB业务的PDSCH译码时延,因此URLLC业务的PDSCH对应的ACK/NACK信息只能等到较晚时间传输,从而增加了URLLC业务的时延。基站在Rel-16URLLC的设计中,需要支持根据上行信道的优先级解决多信道碰撞的问题。
综上所述,在一个HARQ进程的ACK/NACK信息未发送前,该HARQ进程编号不能被重用。当URLLC的某个HARQ进程采用无反馈下行传输时,按照现有的规定,则该进程将无法再被使用,因此降低了实际支持的最大HARQ进程的数量,影响数据传输速率。另外,当多个上行信道发生碰撞时,如果通过基站发送的指示信令确定各信道的优先级,会增加指示信令的开销。为了解决上述技术问题,本申请实施例提供了如下解决方案。
如图6所示,图6是本申请实施例提供的一种数据传输方法的流程示意图。如图所示,本申请实施例中的步骤至少包括:
S601,用户设备接收第一下行控制信息DCI,所述第一DCI用于调度第一物理下行共享信道PDSCH,所述第一DCI包括第一信息域,所述第一信息域包括特定值或者非特定值,所述特定值表示不发送所述第一PDSCH的确认信息、或暂不发送所述第一PDSCH的确认信息。所述第一信息域为PDSCH反馈时序信息域。所述非特定值为PDSCH反馈时序信息域中不包括特定值在内的其他任意值。
具体实现中,用户设备在接收第一DCI之后,可以从第一DCI中的PDSCH-to-HARQ_feedback timing indicator信息域获取特定值,该特定值可以为第一特定值k,例如k的值可以设置为一个无意义的值、或者无穷大的值等,表示该DCI调度的PDSCH无对应的ACK/NACK信息进行反馈。该特定值也可以为第二特定值k,第二特定值k表示用户设备暂不发送第一PDSCH的ACK/NACK信息,后续可以通过触发信令触发用户设备反馈第一PDSCH的ACK/NACK信息。其中,触发信令用于指示所述用户设备发送所述第一PDSCH的确认信息。
S602,用户设备根据所述第一信息域,确定在所述第一PDSCH之后接收的第二PDSCH对应的HARQ进程编号的值或者取值范围。
其中,所述第二PDSCH在所述第一PDSCH对应的确认信息的发送时间之前传输;或者所述第二PDSCH在触发信令的发送时间之前传输。触发信令的传输时间不早于所述第一DCI的传输时间。例如,触发信令的起始时间不早于第一DCI的起始时间,或者触发信令的结束时间不早于第一DCI的起始时间,或者触发信令的起始时间不早于第一DCI的起始时间,或者触发信令的结束时间不早于第一DCI的结束时间。
在一些实施例中,所述第一信息域包括特定值,可以是所述第一信息域包括所述特定值,或者是所述第一信息域携带所述特定值。所述第二PDSCH对应的HARQ进程编号的取值范围包括用户设备所支持的部分或者所有HARQ进程编号。包括以下几种情况:
在特定值表示不发送所述第一PDSCH的确认信息的情况下,用户设备接收第一PDSCH之后,接收第二PDSCH。第一PDSCH采用第一HARQ进程编号,第二PDSCH也可以采用第一HARQ进程编号。这样当第一PDSCH没有对应的ACK/NACK信息进行反馈时,第二PDSCH可以继续使用相同的HARQ进程编号,从而保证的系统传输速率。当然,第一PDSCH采用第一HARQ进程编号,第二PDSCH可以采用第二HARQ进程编号,两者采用不同的进程编号。
例如,如图7所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,由于DCI1中的PDSCH-to-HARQ_feedback timing indicator信息域指示特定值k为无穷大或无意义,因此用户设备向网络设备反馈第一PDSCH1对应的确认信息之前,用户设备接收到的PDSCH2的HARQ进程编号可以与PDSCH1的HARQ进程编号相同,即PDSCH2也可以采用HARQ进程编号X。
在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之前传输时,第一PDSCH采用第一HARQ进程编号,第二PDSCH采用第二HARQ进程编号,第二PDSCH不能使用与第一PDSCH相同的HARQ进程编号。例如,如图8所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,第一PDSCH对应的ACK/NACK信息暂不发送,该ACK/NACK信息由触发信令触发。在接收到PDSCH1之后、且额外信令的发送时间 之前,用户设备接收到的PDSCH2对应的HARQ进程编号不同于PDSCH1对应的HARQ进程编号,即PDSCH2采用HARQ进程编号Y。
在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之后、且所述第一PDSCH对应的确认信息的发送时间之前传输时,第一PDSCH采用第一HARQ进程编号,第二PDSCH也可以采用第一HARQ进程编号。实现在反馈第一PDSCH对应的确认信息之前,可以继续使用相同的HARQ进程编号,保障数据的传输速率。当然,第二PDSCH也可以使用与第一PDSCH不同的HARQ进程编号。如图9所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,第一PDSCH对应的ACK/NACK信息暂不发送,该ACK/NACK信息由触发信令触发。在触发信令的发送时间之后、且用户设备向网络设备发送ACK/NACK信息之前,用户设备接收到的PDSCH2对应的HARQ进程编号可以与PDSCH1对应的HARQ进程编号相同,即PDSCH2也可以采用HARQ进程编号X。
在一些实施例中,当所述第一信息域包括非特定值时,所述第二PDSCH对应的HARQ进程编号的取值范围包括用户设备所支持的所有HARQ进程编号中除去所述第一PDSCH对应的HARQ进程编号之外的其他HARQ进程编号。具体的,用户设备接收第一PDSCH之后,接收第二PDSCH。第一PDSCH采用第一HARQ进程编号,第二PDSCH采用非第一HARQ进程编号,二者采用不同的进程编号。
如图10所示,图10是本申请实施例提供的另一种数据传输方法的流程示意图。如图所示,本申请实施例中的步骤至少包括:
S1001,用户设备接收第一下行控制信息DCI,所述第一DCI用于调度第一物理下行共享信道PDSCH,所述第一DCI包括第一信息域,所述第一信息域包括第一特定值或非第一特定值,所述第一特定值表示不发送所述第一PDSCH对应的确认信息、或暂不发送所述第一PDSCH对应的确认信息。所述第一信息域为PDSCH反馈时序信息域。所述非第一特定值为PDSCH反馈时序信息域中不包括第一特定值在内的其他任意值。
具体实现中,用户设备在接收第一DCI之后,可以从第一DCI中的PDSCH-to-HARQ_feedback timing indicator信息域获取特定值,该特定值可以为第一特定值k,例如该特定值表示无意义、或者无穷大等,表示该DCI调度的PDSCH无对应的ACK/NACK信息进行反馈。该特定值也可以为第二特定值k,第二特定值k表示用户设备暂不发送第一PDSCH的ACK/NACK信息,后续可以通过触发信令触发用户设备反馈第一PDSCH的ACK/NACK信息。其中,触发信令用于指示所述用户设备发送所述第一PDSCH的确认信息。
S1002,当所述第一PDSCH对应的第一上行信道与第二上行信道在时域上至少部分重叠时,所述用户设备根据所述第一信息域,确定所述第一上行信道和所述第二上行信道的优先级。
具体的,用户设备可以根据所述第一信息域包括的所述第一特定值,确定所述第一上行信道和所述第二上行信道的优先级。
在一些实施例中,所述第二上行信道用于承载第二PDSCH的确认信息,所述第二PDSCH由第二DCI调度,第二DCI可以在所述第一DCI之前发送。所述第二DCI包括第二信息域,所述第二信息域包括的值用于指示所述第二上行信道的传输时间,所述第二信息域为PDSCH反馈时序信息域。当所述第二信息域不包括第二特定值、且所述第一信息域包括所述非第一特定值时,用户设备可以确定所述第一上行信道为高优先级,其中,所述第二特定值表示不发送所述第二PDSCH对应的确认信息、或暂不 发送所述第二PDSCH对应的确认信息。通过这种方式确定各个上行信道的优先级,可以避免增加额外的控制信令开销。
在一些实施例中,所述第二上行信道用于承载第二PDSCH的确认信息,所述第二PDSCH由第二DCI调度,第二DCI可以在所述第一DCI之前发送。所述第二DCI包括第二信息域,所述第二信息域包括的值用于指示所述第二上行信道的传输时间,所述第二信息域为PDSCH反馈时序信息域。当所述第二信息域包括所述第二特定值,且所述第一信息域包括所述第一特定值时,用户设备可以确定所述第一上行信道为高优先级,所述第一特定值表示不发送所述第一PDSCH对应的确认信息,所述第二特定值表示暂不发送所述第二PDSCH对应的确认信息。通过这种方式确定各个上行信道的优先级,可以避免增加额外的控制信令开销。
在一些实施例中,用户设备可以根据第一信息域以及所述第一DCI的发送时间,确定所述第一上行信道和所述第二上行信道的优先级。进一步的,当所述第一DCI在第二DCI之后发送、且所述第一信息域包括所述非第一特定值时,用户设备可以确定所述第一上行信道为高优先级,其中,所述第二DCI为所述第二上行信道对应的DCI。或者,所述第二上行信道对应的第二DCI指示的优先级与所述第一DCI指示的优先级相同。这样可以确定各个上行信道的优先级,避免增加额外的控制信令开销。
最后,在确定第一上行信道和第二上行信道优先级之后,如果第一上行信道的优先级高于第二上行信道的优先级,用户设备可以仅传输第一上行信道,而不传输第二上行信道,或者停止传输第二上行信道。或者如果第一上行信道的优先级与第二上行信道的优先级相同,可以将第一上行信道和第二上行信道的中的信息进行复用,然后通过一个上行信道进行传输。但是,在复用传输过程中需要保证第一上行信道中承载的信息被全部传输。如果第一上行信道的优先级低于第二上行信道的优先级,用户设备可以仅传输第二上行信道,而不传输第一上行信道,或者停止传输第一上行信。从而节省了信令的开销。根据各个上行信道的优先级进行数据传输的过程不是本申请的保护重点,本申请实施例不再赘述。
如图11所示,图11是本申请实施例提供的一种数据传输装置的结构示意图。如图所示,本申请实施例中的装置至少包括:

具体实现中,用户设备在接收第一DCI之后,可以从第一DCI中的PDSCH-to-HARQ_feedback timing indicator信息域获取特定值,该特定值可以为第一特定值k,例如k的值可以设置为一个无意义的值、或者无穷大的值等,表示该DCI调度的PDSCH无对应的ACK/NACK信息进行反馈。该特定值也可以为第二特定值k,第二特定值k表示用户设备暂不发送第一PDSCH的ACK/NACK信息,后续可以通过触发信令触发用户设备反馈第一PDSCH的ACK/NACK信息。其中,触发信令用于指示所述用户设备发送所述第一PDSCH的确认信息。

例如,如图7所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,由于DCI1中的PDSCH-to-HARQ_feedback timing indicator信息域指示特定值k为无穷大或无意义,因此用户设备向网络设备反馈第一PDSCH1对应的确认信息之前,用户设备接收到的PDSCH2的HARQ进程编号可以与PDSCH1的HARQ进程编号相同,即PDSCH2也可以采用HARQ进程编号X。
在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之前传输时,第一PDSCH采用第一HARQ进程编号,第二PDSCH采用第二HARQ进程编号,第二PDSCH不能使用与第一PDSCH相同的HARQ进程编号。例如,如图8所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,第一PDSCH对应的ACK/NACK信息暂不发送,该ACK/NACK信息由触发信令触发。在接收到PDSCH1之后、且额外信令的发送时间之前,用户设备接收到的PDSCH2对应的HARQ进程编号不同于PDSCH1对应的HARQ进程编号,即PDSCH2采用HARQ进程编号Y。
在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之后、且所述第一PDSCH对应的确认信息的发送时间之前传输时,第一PDSCH采用第一HARQ进程编号,第二PDSCH也可以采用第一HARQ进程编号。实现在反馈第一PDSCH对应的确认信息之前,可以继续使用相同的HARQ进程编号,保障数据的传输速率。当然,第二PDSCH也可以使用与第一PDSCH不同的HARQ进程编号。如图9所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,第一PDSCH对应的ACK/NACK信息暂不发送,该ACK/NACK信息由触发信令触发。在触发信令的发送时间之后、且用户设备向网络设备发送ACK/NACK信息之前,用户设备接收到的PDSCH2对应的HARQ进程编号可以与PDSCH1对应的HARQ进程编号相同,即PDSCH2也可以采用HARQ进程编号X。
在一些实施例中,当所述第一信息域包括非特定值时,所述第二PDSCH对应的HARQ进程编号的取值范围包括用户设备所支持的所有HARQ进程编号中除去所述第一PDSCH对应的HARQ进程编号之外的其他HARQ进程编号。具体的,用户设备接收第一PDSCH之后,接收第二PDSCH。第一PDSCH采用第一HARQ进程编号,第二PDSCH采用非第一HARQ进程编号,二者采用不同的进程编号。

在一些实施例中,所述第二上行信道用于承载第二PDSCH的确认信息,所述第二PDSCH由第二DCI调度,第二DCI可以在所述第一DCI之前发送。所述第二DCI包括第二信息域,所述第二信息域包括的值用于指示所述第二上行信道的传输时间,所述第二信息域为PDSCH反馈时序信息域。当所述第二信息域不包括第二特定值、且所述第一信息域包括非第一特定值时,用户设备可以确定所述第一上行信道为高优先级,其中,所述第二特定值表示不发送所述第二PDSCH对应的确认信息、或暂不发送所述第二PDSCH对应的确认信息。通过这种方式确定各个上行信道的优先级,可以避免增加额外的控制信令开销。
在一些实施例中,所述第二上行信道用于承载第二PDSCH的确认信息,所述第二PDSCH由第二DCI调度,第二DCI可以在所述第一DCI之前发送。所述第二DCI包括第二信息域,所述第二信息域包括的值用于指示所述第二上行信道的传输时间,所述第二信息域为PDSCH反馈时序信息域。当所述第二信息域包括所述第二特定值,且所述第一信息域包括所述第一特定值,所述用户设备确定所述第一上行信道为高优先级,所述第一特定值表示不发送所述第一PDSCH对应的确认信息,所述第二特定值表示暂不发送所述第二PDSCH对应的确认信息。通过这种方式确定各个上行信道的优先级,可以避免增加额外的控制信令开销。
在一些实施例中,用户设备可以根据第一信息域以及所述第一DCI的发送时间,确定所述第一上行信道和所述第二上行信道的优先级。进一步的,当所述第一DCI在第二DCI之后发送、且所述第一信息域包括所述非第一特定值时,用户设备可以确定所述第一上行信道为高优先级,其中,所述第二DCI为所述第二上行信道对应的DCI。或者,所述第二上行信道对应的第二DCI指示的优先级与所述第一DCI指示的优先级相同。这样可以确定各个上行信道的优先级,避免增加额外的控制信令开销。
最后,在确定第一上行信道和第二上行信道优先级之后,如果第一上行信道的优先级高于第二上行信道的优先级,用户设备可以仅传输第一上行信道,而不传输第二上行信道,或者停止传输第二上行信 道。或者如果第一上行信道的优先级与第二上行信道的优先级相同,可以将第一上行信道和第二上行信道的中的信息进行复用,然后通过一个上行信道进行传输。但是,在复用传输过程中需要保证第一上行信道中承载的信息被全部传输。如果第一上行信道的优先级低于第二上行信道的优先级,用户设备可以仅传输第二上行信道,而不传输第一上行信道,或者停止传输第一上行信。从而节省了信令的开销。根据各个上行信道的优先级进行数据传输的过程不是本申请的保护重点,本申请实施例不再赘述。
如图12所示,图12是本申请实施例提供的一种数据传输装置的结构示意图。如图所示,本申请实施例中的装置至少包括:
发送模块1201,用于向用户设备发送第一下行控制信息DCI,所述第一DCI用于调度第一物理下行共享信道PDSCH,所述第一DCI包括第一信息域,所述第一信息域包括特定值或非特定值,所述特定值表示不发送所述第一PDSCH的确认信息、或暂不发送所述第一PDSCH的确认信息,所述第一信息域用于指示所述用户设备确定在所述第一PDSCH之后接收的第二PDSCH对应的混合自动重传请求HARQ进程编号的值或取值范围。所述非特定值为PDSCH反馈时序信息域中不包括特定值在内的其他任意值。
其中,该特定值可以为第一特定值k,例如k的值可以设置为一个无意义的值、或者无穷大的值等,表示该DCI调度的PDSCH无对应的ACK/NACK信息进行反馈。该特定值也可以为第二特定值k,第二特定值k表示用户设备暂不发送第一PDSCH的ACK/NACK信息,后续可以通过触发信令触发用户设备反馈第一PDSCH的ACK/NACK信息。其中,触发信令用于指示所述用户设备发送所述第一PDSCH的确认信息。
其中,所述第二PDSCH在所述第一PDSCH对应的确认信息的发送时间之前传输;或者所述第二PDSCH在触发信令的发送时间之前传输。触发信令的传输时间不早于所述第一DCI的传输时间。例如,触发信令的起始时间不早于第一DCI的起始时间,或者触发信令的结束时间不早于第一DCI的起始时间,或者触发信令的起始时间不早于第一DCI的起始时间,或者触发信令的结束时间不早于第一DCI的结束时间。
在一些实施例中,所述第一信息域包括所述特定值,可以是所述第一信息域包括所述特定值,或者是所述第一信息域携带所述特定值。所述第二PDSCH对应的HARQ进程编号的取值范围包括用户设备所支持的部分或者所有HARQ进程编号。包括以下几种情况:
在特定值表示不发送所述第一PDSCH的确认信息的情况下,网络设备发送第一PDSCH之后,发送第二PDSCH。第一PDSCH采用第一HARQ进程编号,第二PDSCH也可以采用第一HARQ进程编号。这样当第一PDSCH没有对应的ACK/NACK信息进行反馈时,第二PDSCH可以继续使用相同的HARQ进程编号,从而保证的系统传输速率。当然,第一PDSCH采用第一HARQ进程编号,第二PDSCH可以采用第二HARQ进程编号,两者采用不同的进程编号。
例如,如图7所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,由于DCI1中的PDSCH-to-HARQ_feedback timing indicator信息域指示特定值k为无穷大或无意义,因此用户设备向网络设备反馈第一PDSCH1对应的确认信息之前,网络设备发送的PDSCH2的HARQ进程编号可以与PDSCH1的HARQ进程编号相同,即PDSCH2也可以采用HARQ进程编号X。
在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之前传输时,第一PDSCH采用第一HARQ进程编号,第二PDSCH采用第二HARQ进程编号,第二PDSCH不能使用与第一PDSCH相同的HARQ进程编号。例如,如图8所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,第一PDSCH对应的ACK/NACK信息暂不发送,该ACK/NACK信息由触发信令触发。在用户设备接收到PDSCH1之后、且额外信令的发送时间之前,用户设备接收到的PDSCH2对应的HARQ进程编号不同于PDSCH1对应的HARQ进程编号,即PDSCH2采用HARQ进程编号Y。
在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之后、且所述第一PDSCH对应的确认信息的发送时间之前传输时,第一PDSCH采用第一HARQ进程编号,第二PDSCH也可以采用第一HARQ进程编号。实现在反馈第一PDSCH对应的确认信息之前,可以继续使用相同的HARQ进程编号,保障数据的传输速率。当然,第二PDSCH也可以使用与第一PDSCH不同的HARQ进程编号。如图9所示,DCI1用于调度PDSCH1,DCI2用于调度PDSCH2,PDSCH1采用HARQ进程编号X,第一PDSCH对应的ACK/NACK信息暂不发送,该ACK/NACK信息由触发信令触发。在触发信令的发送时间之后、且用户设备向网络设备发送ACK/NACK信息之前,用户设备接收到的PDSCH2对应的HARQ进程编号可以与PDSCH1对应的HARQ进程编号相同,即PDSCH2也可以采用HARQ进程编号X。
在一些实施例中,当所述第一信息域包括非特定值时,所述第二PDSCH对应的HARQ进程编号的取值范围包括用户设备所支持的所有HARQ进程编号中除去所述第一PDSCH对应的HARQ进程编号之外的其他HARQ进程编号。具体的,用户设备接收第一PDSCH之后,接收第二PDSCH。第一PDSCH采用第一HARQ进程编号,第二PDSCH采用非第一HARQ进程编号,二者采用不同的进程编号。
进一步地,所述装置还包括:接收模块1202,用于接收所述用户设备根据所述HARQ进程编号的值或取值范围发送的第二PDSCH对应的确认信息。
具体实现中,在特定值表示不发送所述第一PDSCH的确认信息的情况下,可以接收用户设备使用与第一PDSCH的相同HARQ进程编号发送的第二PDSCH对应的确认信息。在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之前传输时,可以接收用户设备使用与第一PDSCH的不同HARQ进程编号发送的第二PDSCH对应的确认信息。在特定值表示暂不发送所述第一PDSCH的确认信息的情况下,当第二PDSCH在触发信令的发送时间之后、且所述第一PDSCH对应的确认信息的发送时间之前传输时,可以接收用户设备使用与第一PDSCH的相同HARQ进程编号发送的第二PDSCH对应的确认信息。
在另一个实施例中:
发送模块1201,用于向用户设备发送第一下行控制信息DCI,所述第一DCI用于调度第一物理下行共享信道PDSCH,所述第一DCI包括第一信息域,所述第一信息域包括第一特定值或非第一特定值,所述第一特定值表示不发送所述第一PDSCH对应的确认信息、或暂不发送所述第一PDSCH对应的确认信息,所述第一信息域用于指示所述用户设备当所述第一PDSCH对应的第一上行信道与第二上行信道在时域上至少部分重叠时确定所述第一上行信道和所述第二上行信道的优先级。。所述非第一特定值为PDSCH反馈时序信息域中不包括第一特定值在内的其他任意值。
其中,该特定值可以为第一特定值k,例如该特定值表示无意义、或者无穷大等,表示该DCI调度 的PDSCH无对应的ACK/NACK信息进行反馈。该特定值也可以为第二特定值k,第二特定值k表示用户设备暂不发送第一PDSCH的ACK/NACK信息,后续可以通过触发信令触发用户设备反馈第一PDSCH的ACK/NACK信息。其中,触发信令用于指示所述用户设备发送所述第一PDSCH的确认信息。
在一些实施例中,所述第二上行信道用于承载第二PDSCH的确认信息,所述第二PDSCH由第二DCI调度,第二DCI可以在所述第一DCI之前发送。所述第二DCI包括第二信息域,所述第二信息域包括的值用于指示所述第二上行信道的传输时间,所述第二信息域为PDSCH反馈时序信息域。当所述第二信息域不包括第二特定值、且所述第一信息域包括非第一特定值时,所述第一上行信道为高优先级,其中,所述第二特定值表示不发送所述第二PDSCH对应的确认信息、或暂不发送所述第二PDSCH对应的确认信息。通过这种方式确定各个上行信道的优先级,可以避免增加额外的控制信令开销。
在一些实施例中,所述第二上行信道用于承载第二PDSCH的确认信息,所述第二PDSCH由第二DCI调度,第二DCI可以在所述第一DCI之前发送。所述第二DCI包括第二信息域,所述第二信息域包括的值用于指示所述第二上行信道的传输时间,所述第二信息域为PDSCH反馈时序信息域。当所述第二信息域包括所述第二特定值,且所述第一信息域包括所述第一特定值,所述第一上行信道为高优先级,所述第一特定值表示不发送所述第一PDSCH对应的确认信息,所述第二特定值表示暂不发送所述第二PDSCH对应的确认信息。通过这种方式确定各个上行信道的优先级,可以避免增加额外的控制信令开销。
在一些实施例中,所述第一上行信道和所述第二上行信道的优先级为根据第一信息域以及所述第一DCI的发送时间确定的。进一步的,当所述第一DCI在第二DCI之后发送、且所述第一信息域包括所述非第一特定值时,所述第一上行信道为高优先级,其中,所述第二DCI为所述第二上行信道对应的DCI。或者,所述第二上行信道对应的第二DCI指示的优先级与所述第一DCI指示的优先级相同。以便用户设备可以确定各个上行信道的优先级,避免增加额外的控制信令开销。
进一步地,接收模块1202,还用于接收用户设备根据所述第一上行信道和所述第二上行信道优先级发送的确认信息。
具体实现中,在确定第一上行信道和第二上行信道优先级之后,如果第一上行信道的优先级高于第二上行信道的优先级,可以接收用户设备发送的第一上行信道承载的确认信息,用户设备可以不传输第二上行信道,或者停止传输第二上行信道。如果第一上行信道的优先级与第二上行信道的优先级相同,可以接收用户设备发送的第一上行信道和第二上行信道进行复用后承载的确认信息。如果第一上行信道的优先级低于第二上行信道的优先级,可以接收用户设备发送的第二上行信道承载的确认信息,用户设备不传输第一上行信道,或者停止传输第一上行信。从而节省了信令的开销。
