为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
NR系统中支持两种肯定应答(Acknowledgement,ACK)/否定应答(Negative Acknowledgement,NACK)信息生成方式:Type-1反馈码本(即半静态HARQ-ACK码本(semi-static HARQ-ACK codebook))和Type-2反馈码本(即动态HARQ-ACK码本(dynamic HARQ-ACK codebook))。Type-1反馈码本采用半静态的方式确定物理下行共享信道(Physical Downlink Shared Channel,PDSCH)对应的ACK/NACK反馈信息的比特数量,即反馈码本中包括的ACK/NACK比特数量不依赖于实际接收到的PDSCH数量,而是根据半静态配置的可用于传输PDSCH的下行资源(即最大可接收到的PDSCH数量)确定。Type-2反馈码本主要解决反馈开销问题,即根据实际调度的PDSCH数量确定ACK/NACK信息数量。
进一步的,NR系统支持基于全部混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程进行ACK/NACK反馈的方式,即采用Type-3HARQ-ACK码本(codebook)传输ACK/NACK反馈信息。具体的,终端支持最大N个HARQ进程。当基站发送下行控制信息(Downlink Control Information,DCI)触发终端发送Type-3HARQ-ACK码本时,不论终端实际收到多个HARQ进程,总是将向基站反馈N个进程对应的ACK/NACK反馈信息。ACK/NACK信息按照先HARQ进程编号顺序再载波编号映射到反馈信息码本(codebook)中。未接收到的HARQ进程对应的ACK/NACK信息设置为占位信息(如NACK)。以图2为例,对Type-3HARQ-ACK码本结构进行说明。假设终端配置了3个小区(载波)进行数据传输,其中小区1上最大支持8个HARQ进程,小区2上最大支持4个HARQ进程,小区3上最大支持16个HARQ进程。所有小区上支持的最大码字数为1,即一个PDSCH内只承载一个传输块(Transmission Block,TB),对应一比特ACK/NACK反馈信息。在一种实现方式中,反馈码本中包括{b 1,1,……,b 1,8,b 2,1,……,b 2,4,b 3,1,……,b 3,16},其中b i,j为小区i上HARQ进程j对应的ACK/NACK反馈信息。在另一种实现方式中,反馈码本中包括{b 1,1,NDI 1,1,……,b 1,8,NDI 1,8,b 2,1,NDI 2,1,……,b 2,4,NDI 2,4,b 3,1,NDI 3,1,……,b 3,16,NDI 3,16},其中b i,j为小区i上HARQ进程j对应的ACK/NACK反馈信息,NDI i,j为小区i上终端最后收到的HARQ进程j对应的新数据指示(New Data Indicator,NDI)信息。
更进一步的,NR系统支持增强的Type-3HARQ-ACK反馈码本,即eType-3码本,旨在压缩反馈开销,即基站可以触发终端反馈部分HARQ进程的反馈信息。具体地,高层信令预配置若干小区集合或HARQ进程集合,每个集合内包括部分小区或HARQ进程,DCI信令触发终端反馈预配置集合中的某一个集合对应的反馈信息。以图2为例,高层信令预配置4个小区(Cell)集合,如表1所示,DCI触发信令指示集合,3,则终端发送的反馈码本为{b 2,1,……,b 2,4,b 3,1,……,b 3,16},其中b i,j为小区i上HARQ进程j对应的ACK/NACK反馈信息。表2给出了一种HARQ进程集合配置的例子,具体可参考小区集合的示例,在此不再展开说明。

为了更好的支持超高可靠低时延通信(Ultra-reliable low latency,URLLC)业务,支持基于子时隙的(subslot-based)ACK/NACK反馈,即ACK/NACK反馈的时间间隔以子时隙(subslot)为粒度确定,且承载该ACK/NACK的物理上行控制信道(Physical Uplink Control Channel,PUCCH)在一个子时隙内传输,其中,子时隙可以是2个符号或7个符号。另外物理信道可配置2级优先级(2-level priority),即高优先级(High Priority,HP)或低优先级(Low Priority,LP)。高优先级的业务和低优先级的业务对应的ACK/NACK反馈粒度可以独立配置,例如,高优先级的业务的ACK/NACK采用基于子时隙的(subslot-based)反馈,而低优先级的业务的ACK/NACK采用基于时隙的(slot-based)反馈。对于时延敏感的URLLC业务可以配置subslot-based ACK/NACK反馈且指示为高优先级。
为了便于理解本申请实施例,以下对本申请所解决的问题进行说明。
由于Type 3/eType 3码本是由基站动态触发的,且其中承载的反馈信息较为完整,在传输etype 3码本的PUCCH所在的时间单元中,终端不期待有其他待传输的Type 1/Type 2码本中承载的ACK/NACK信息未包含在该eType 3码本中。然而,当承载eType 3码本和Type 1/Type 2码本的PUCCH分别对应不同的时域粒度时(如一个为时隙(slot),另一个为子时隙(subslot)),上述结论会造成不必要的限制。以图3为例,LP eType 3码本通过slot-based PUCCH传输,HP type 2码本通过subslot-based PUCCH传输,两个信道无重叠,则终端将在该slot内传输PUCCH 1和PUCCH 2。按照上述结论的约束,HP type 2码本中的所有ACK/NACK信息必须都包含在LP eType 3码本中,对应的反馈信息被传输两次,造成冗余传输,降低上行效率,浪费终端功耗。另一方面,为了保证LP eType 3码本中包括HP type 2码本中的所有ACK/NACK信息,则触发信令必须要指示一个较大的小区集合或HARQ进程集合,引入额外的反馈开销,降低上行效率,浪费终端功耗。
基于上述问题,本申请提出一种反馈方案,在需要同时传输Type 3/eType 3码本和Type 1/Type 2码本的情况下,Type 1/Type 2码本中的反馈信息可以映射到Type 3/eType 3码本,从而可以降低反馈开销,以及提升上行传输效率。
以下通过具体实施例详述本申请的技术方案。
图4是根据本申请实施例的无线通信的方法200的示意性流程图,如图4所示,该无线通信的方法200可以包括如下内容中的至少部分内容:
S210,网络设备向终端设备发送第一信息;其中,该第一信息用于指示在第一时间单元内传输第一反馈码本,该第一反馈码本中包括第二反馈码本中的反馈信息,该第二反馈码本在第二时间单元内传输;其中,该第二时间单元与该第一时间单元重叠,或者,承载该第二反馈码本的PUCCH占有的时域资源与该第一时间单元重叠,或者,承载该第二反馈码本的PUCCH与承载该第一反馈码本的PUCCH重叠;
S220,该终端设备接收该第一信息。
在本申请实施例中,在第二时间单元与第一时间单元重叠的情况下,第一反馈码本中可以包括第二反馈码本中的反馈信息;或者,在承载第二反馈码本的PUCCH占有的时域资源与第一时间单元重叠的情况下,第一反馈码本中可以包括第二反馈码本中的反馈信息;或者,在承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH重叠的情况下,第一反馈码本中可以包括第二反馈码本中的反馈信息。也即,在相同时间单元中同时配置传输第一反馈码本和第二反馈码本的情况下,第二反馈码本中的反馈信息可以映射到第一反馈码本,终端设备可以无需传输第二反馈码本,从而可以降低反馈开销,以及提升上行传输效率。
换句话说,在本申请实施例中,在第二时间单元与第一时间单元重叠的情况下,终端设备不期待第二反馈码本中的反馈信息不能映射到第一反馈码本中,或者,终端设备期待第二反馈码本中的反馈信息能够映射到第一反馈码本中;或者,在承载第二反馈码本的PUCCH占有的时域资源与第一时间单元重叠的情况下,终端设备不期待第二反馈码本中的反馈信息不能映射到第一反馈码本中,或者,终端设备期待第二反馈码本中的反馈信息能够映射到第一反馈码本中;或者,在承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH重叠的情况下,终端设备不期待第二反馈码本中的反馈信息不能映射到第一反馈码本中,或者,终端设备期待第二反馈码本中的反馈信息能够映射到第一反馈码本中。
在本申请实施例中,第二时间单元与第一时间单元重叠,可以是指:第二时间单元与第一时间单元部分重叠,或者,第二时间单元与第一时间单元完全重叠。同理,承载第二反馈码本的PUCCH占 有的时域资源与第一时间单元重叠,可以是指:承载第二反馈码本的PUCCH占有的时域资源与第一时间单元部分重叠,或者,承载第二反馈码本的PUCCH占有的时域资源与第一时间单元完全重叠。同理,承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH重叠,可以是指:承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH部分重叠,或者,承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH完全重叠。
在一些实施例中,该第一反馈码本为类型3(Type 3,或者,Type-3)码本,或,该第一反馈码本为增强的类型3(eType 3,或者,eType-3)码本。
在一些实施例中,该第二反馈码本为类型1(Type 1,或者,Type-1)码本,或,该第二反馈码本为类型2(Type 2,或者,Type-2)码本。
在一些实施例中,承载该第一反馈码本的PUCCH在该第一时间单元内传输,承载该第二反馈码本的PUCCH在该第二时间单元内传输。
在一些实施例中,该第一时间单元与该第二时间单元的长度不同。
具体例如,该第一时间单元的长度为以下之一:时隙,子时隙,N个符号;和/或,该第二时间单元的长度为以下之一:时隙,子时隙,M个符号;其中,N和M均为正整数。
例如,第一时间单元的长度为一个时隙,第二时间单元的长度为一个子时隙。
又例如,第一时间单元的长度为一个子时隙,第二时间单元的长度为一个时隙。
再例如,第一时间单元的长度为N个符号,第二时间单元的长度为M个符号。
需要说明的是,一个子时隙可以包含2个符号或7个符号。
示例1,假设:第二时间单元与第一时间单元重叠为条件一,承载第二反馈码本的PUCCH占有的时域资源与第一时间单元重叠为条件二,承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH重叠为条件三;以及假设:第一反馈码本为eType 3码本,第二反馈码本为Type 2码本。例如,如图5所示,网络设备在一个时隙(slot)内指示终端设备传输一个基于子时隙的(subslot-based)eType 3码本和一个基于时隙的(slot-based)Type 2码本。也即,eType 3码本在一个子时隙(subslot)(即图5所示的时隙内的子时隙1)内传输,Type 2码本在一个时隙(slot)内传输。
在示例1中,采用条件一:对于图5中的a~c,eType 3码本要包括Type 2码本中的所有ACK/NACK信息,因为Type 2码本占有的slot与subslot 1满足重叠关系。
在示例1中,采用条件二:对于图5中的a、b,eType 3码本要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH 2与subslot 1重叠。对于图5中的c,eType 3码本不需要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH 2与subslot 1不重叠。
在示例1中,采用条件三:对于图5中的a,eType 3码本要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH 2与PUCCH 1重叠。对于图5中的b、c,eType 3码本不需要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH 2与PUCCH 1不重叠。
示例2,假设:第二时间单元与第一时间单元重叠为条件一,承载第二反馈码本的PUCCH占有的时域资源与第一时间单元重叠为条件二,承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH重叠为条件三;以及假设:第一反馈码本为eType 3码本,第二反馈码本为Type 2码本。例如,如图6所示,网络设备在一个时隙(slot)内指示终端设备传输一个基于时隙的(slot-based)eType3码本和一个基于子时隙的(subslot-based)Type 2码本。也即,Type 2码本在一个子时隙(subslot)(即图6所示的时隙内的子时隙1)内传输,eType 3码本在一个时隙(slot)内传输。
在示例2中,采用条件一:对于图6中的a~c,eType 3码本要包括Type 2码本中的所有ACK/NACK信息,因为Type 2码本占有的subslot 1与slot满足重叠关系。
在示例2中,采用条件二:对于图6中的a~c,eType 3码本要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH与slot满足重叠关系。
在示例2中,采用条件三:对于图6中的a,eType 3码本要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH 2与PUCCH 1重叠。对于图6中的b、c,eType 3码本不需要包括Type 2码本中的所有ACK/NACK信息,因为承载Type 2码本的PUCCH 2与PUCCH 1不重叠。
在一些实施例中,该第一反馈码本中包括第一小区集合中的HARQ进程对应的反馈信息,该第一小区集合中包括至少一个配置给该终端设备的小区。
需要说明的是,第一小区集合可以是配置给该终端设备的至少一个小区集合中的一个小区集合。
在一些实施例中,该第一反馈码本中包括第一HARQ进程集合中的HARQ进程对应的反馈信息,该第一HARQ进程集合中包括至少一个配置给该终端设备的HARQ进程。
需要说明的是,第一HARQ进程集合可以是配置给该终端设备的至少一个HARQ进程集合中的一个HARQ进程集合。
在一些实施例中,该配置给该终端设备的HARQ进程包括配置给该终端设备的至少一个小区的至少一个HARQ进程。
在一些实施例中,该第一反馈码本中包括第二反馈码本中的反馈信息,包括:该第一反馈码本中包括该第二反馈码本中包括的所有信息比特。也即,可以将该第二反馈码本中包括的所有信息比特映射到该第一反馈码本。
在一些实施例中,该第一反馈码本中包括第二反馈码本中的反馈信息,包括:该第一反馈码本中包括该第二反馈码本中包括的信息比特对应的HARQ进程对应的反馈信息。也即,可以仅将该第二反馈码本中包括的信息比特对应的HARQ进程对应的反馈信息映射到该第一反馈码本。
在一些实施例中,该第一反馈码本中包括第二反馈码本中的反馈信息,包括:该第一反馈码本中包括该第二反馈码本中包括的第一反馈信息,其中,该第一反馈信息为第一下行信道对应的反馈信息,该第一反馈信息的传输位置位于该第二时间单元是根据预配置的反馈时间和该第一下行信道的结束符号所在的第三时间单元确定的。也即,可以仅将该第二反馈码本中包括的第一反馈信息映射到该第一反馈码本。可选地,该反馈时间可以是网络设备通过DCI或高层信令指示的。当然,该反馈时间也可以由协议约定,本申请对此并不限定。
具体例如,第一下行信道的结束符号在时间单元n中,DCI或高层信令指示k1(即预配置的反馈时间为k1),则该第一下行信道的反馈信息在时间单元n+k1中传输。
示例3,假设:该第一反馈码本中包括该第二反馈码本中包括的所有信息比特为方式A,该第一反馈码本中包括该第二反馈码本中包括的信息比特对应的HARQ进程对应的反馈信息为方式B,该第一反馈码本中包括该第二反馈码本中包括的该第一反馈信息为方式C;以及假设:第一反馈码本为eType 3码本,第二反馈码本为Type 1码本。具体地,根据预配置的反馈时间K1集合{1,2,3,4}确定subslot n+4中传输的Type 1码本包括4比特反馈信息,每个比特分别对应subslot n~subslot n+3。Subsot n中未收到PDSCH,subslot n+4中的Type 1码本中对应的比特位置为NACK。subslot n+1中收到的PDSCH承载HARQ进程X,其对应的反馈时间k1=3,即其对应的反馈信息通过subslot n+4中的Type 1码本(承载于PUCCH a)传输,根据译码结果对应的比特位置为ACK或NACK。类似的PDSCH 2承载HARQ进程Y,其反馈信息也通过subslot n+4中Type 1码本(承载于PUCCH a)传输,根据译码结果对应的比特位置为ACK或NACK。PDSCH 3承载HARQ进程Z,虽然占有slot n+3传输,即subslot n+4的Type 1码本中包括对应的比特位,但根据反馈时间k1确定其对应的反馈信息将在subslot n+6中传输,所以subslot n+4的Type 1码本对应的比特位置为NACK,如图7所示。
在示例3中,采用方式A:若基站触发了一个slot-based eType 3码本,该eType 3码本所在slot与subslot 4重叠,则该eType 3码本中必须包含PDSCH 1、PDSCH 2和PDSCH 3所承载HARQ进程X、Y、Z对应的反馈信息,但PDSCH 3所承载HARQ进程Z对应的反馈信息设为NACK,即保持和Type 1码本中相同。
在示例3中,采用方式B:Type 1码本中有subslot n+3对应比特位,即PDSCH 3对应的比特位,虽然没有有效的反馈信息。若基站触发了一个slot-based eType 3码本,该eType 3码本所在slot与subslot 4重叠,则该eType 3码本中必须包含PDSCH 1、PDSCH 2和PDSCH 3所承载HARQ进程X、Y、Z对应的反馈信。此时基于对HARQ进程Z的译码结果设置对应的反馈信息,即HARQ进程Z对应的信息不强制为NACK。进一步地,若PDSCH 3满足处理时延,即PDSCH 3的结束位置与PUCCH b的起始位置之间的间隔不小于预定值,则根据译码结果设置HARQ进程Z对应的反馈信息。
在示例3中,采用方式C:若基站触发了一个slot-based eType 3码本,该eType 3码本所在slot与subslot 4重叠,则该eType 3码本中必须包含PDSCH 1和PDSCH 2所承载HARQ进程X、Y对应的反馈信息,而不限制包括PDSCH 3所承载HARQ进程Z的反馈信息。
在一些实施例中,该第一信息可以通过以下之一承载:下行控制信息(Downlink Control Information,DCI),无线资源控制(Radio Resource Control,RRC)信令,媒体接入控制控制元素(Media Access Control Control Element,MAC CE)。
因此,在本申请实施例中,在第二时间单元与第一时间单元重叠的情况下,第一反馈码本中可以包括第二反馈码本中的反馈信息;或者,在承载第二反馈码本的PUCCH占有的时域资源与第一时间单元重叠的情况下,第一反馈码本中可以包括第二反馈码本中的反馈信息;或者,在承载第二反馈码本的PUCCH与承载第一反馈码本的PUCCH重叠的情况下,第一反馈码本中可以包括第二反馈码本中的反馈信息。也即,在相同时间单元中同时配置传输第一反馈码本和第二反馈码本的情况下,第二反馈码本中的反馈信息可以映射到第一反馈码本,终端设备可以无需传输第二反馈码本,从而可以降低反馈开销,以及提升上行传输效率。
