这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
如图1所示,本公开实施例提供的传输物理下行共享信道的方法可应用于无线通信系统100,该无线通信系统可以包括用户设备101以及网络设备102。其中,用户设备101被配置为支持载波聚合,用户设备101可连接至网络设备102的多个载波单元,包括一个主载波单元以及一个或多个辅载波单元。
应理解,以上无线通信系统100既可适用于低频场景,也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(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、全球互联微波接入(worldwide interoperability for micro wave access,WiMAX)通信系统、云无线接入网络(cloud radio access network,CRAN)系统、未来的第五代(5th-Generation,5G)系统、新无线(new radio,NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network,PLMN)系统等。
以上所示用户设备101可以是用户设备(user equipment,UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station,MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或用户设备等。该用户设备101可具备无线收发功能,其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信),并接受网络设备提供的网络服务,这里的网络设备包括但不限于图示网络设备102。
其中,用户设备101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)设备、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网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
网络设备102可以是接入网设备(或称接入网站点)。其中,接入网设备是指有提供网络接入功能的设备,如无线接入网(radio access network,RAN)基站等等。网络设备102具体可包括基站(base station,BS),或包括基站以及用于控制基站的无线资源管理设备等。该网络设备102还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的通信芯片。
比如,网络设备102包括但不限于:5G中的下一代基站(gnodeB,gNB)、LTE系统中的演进型节点B(evolved node B,eNB)、无线网络控制器(radio network controller,RNC)、WCDMA系统中的节点B(node B,NB)、CRAN系统下的无线控制器、基站控制器(basestation controller,BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(baseband unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)或移动交换中心等。
图2是部分TDRA要素的示意图,其中,TDRA要素可以包括行索引(row index)、解调参考信号位置(dmrs-typeA-position)、PDSCH mapping type(映射类型)、k 0和SLIV(包括起始指示符S和长度指示符L)。在实现多时隙物理下行共享信道调度(multi-slot PDSCH scheduling)过程中,网络设备102可通过无线资源控制(RRC)层配置图2所示的TDRA要素表。其中,k 0用于指示DCI所在的时隙与分配的PDSCH的时隙的间隔,若k 0=0,则DCI所在的时隙与分配的PDSCH的时隙相同。
其中,TDRA要素表中至少有1行的要素包含了N种(N>1){k0,mapping type,SLIV}组合,N即为multi-slot PDSCH的个数。网络设备102发送的DCI中TDRA域(field)指向TDRA要素表中的某行TDRA element,若该行TDRA element包含了N(N>1)种{k0,mapping type,SLIV}组合,则该DCI可以调度N个PDSCH。
在NR 52.6-71GHz对应于非授权频谱的场景中,在非授权频谱上,发送端占用信道有最大占用时长(MCOT)的限制,若某个发送端的COT结束,发送端将不能再发送数据。结合图2可知,multi-slot PDSCH的个数通过RRC层配置,存在PDSCH传输时长超出基站为其配置的COT的情况。
比如,在TDRA要素表中某行TDRA element对应的N=8(对应于多时隙物理下行共享信道),其余行的N=1(对应于单时隙物理下行共享信道)。为降低DCI开销,网络设 备102选择用1个DCI调度8个PDSCH,而非采用多次调度单个PDSCH。但此种情况下,8个PDSCH中可能会有1个或多个PDSCH超出基站的COT结束位置。
因此,在PDSCH超出COT结束位置的场景中需要解决PDSCH的有效传输问题。
本公开实施例提供了一种传输物理下行共享信道的方法。参照图3,图3是根据一示例性实施例示出的传输物理下行共享信道的方法的流程图,如图3所示,此方法包括:
步骤S31、网络设备102向用户设备101发送第一指示信息,其中,第一指示信息用于指示物理下行共享信道PDSCH接收方式是第一方式或第二方式。
步骤S32、用户设备101确定物理下行共享信道PDSCH接收方式;其中,PDSCH接收方式是第一方式或第二方式。
步骤S33、网络设备102向用户设备101发送下行控制信息;其中,下行控制信息包括用于指示COT结束位置的信息。
步骤S34、用户设备101监听并接收网络设备102下行控制信息;其中,下行控制信息包括用于指示COT结束位置的信息。
步骤S35、网络设备102向用户设备101发送PDSCH。
步骤S36、用户设备101以确定的PDSCH接收方式接收网络设备102发送的PDSCH。
其中,第一方式对应于用户设备101监听到包括COT结束位置的控制指示信息后,接收位于COT结束位置之前的PDSCH,并且不接收位于COT结束位置之后的PDSCH;
第二方式对应于用户设备101监听到包括COT结束位置的控制指示信息后,接收位于COT结束位置之前的PDSCH,并且接收COT结束位置之后的PDSCH。
本公开实施例中,用户设备101通过监听的方式可以获知COT的结束位置。在获知COT结束位置后,用户设备101既可以通过第一方式接收PDSCH,即接收位于COT结束位置之前的PDSCH,而停止接收超出COT结束位置的PDSCH;用户设备101也可以通过第二方式接收PDSCH,即接收位于COT结束位置之前的PDSCH,并且继续接收超出COT结束位置的PDSCH。从而,用户设备101可以合理处理超出COT的PDSCH部分,高效处理和接收PDSCH。
本方法中,设置两种不同的PDSCH接收方式,从而为用户设备提供两种不同的方式用于处理位于COT结束位置之后的PDSCH,为用户设备提供更多的可选方案,使用户设备可以根据不同的使用需求使用相应的PDSCH接收方式,从而高效的进行PDSCH的接收。
本公开实施例提供了一种接收物理下行共享信道的方法。此方法被用户设备101执行。此方法包括:
步骤S1-1、用户设备101确定物理下行共享信道PDSCH接收方式;其中,PDSCH接收方式是第一方式或第二方式。

步骤S1-2、用户设备101监听并接收下行控制信息;其中,下行控制信息包括用于指示COT结束位置的信息。
步骤S1-3、用户设备101以确定的PDSCH接收方式接收所述PDSCH。
在一些可能的实施方式中,用户设备101在以第一方式接收PDSCH时,即当用户设备101接收位于COT结束位置之前的PDSCH,而停止接收超出COT结束位置的PDSCH时,网络设备102不需要继续传输(resume)超出COT结束位置的PDSCH,但是可以在重新占用信道后重新调度PDSCH。
在一些可能的实施方式中,用户设备101在以第二方式接收PDSCH时,即当用户设备101接收位于COT结束位置之前的PDSCH,并且继续接收超出COT结束位置的PDSCH时,网络设备102需要再次发起信道占用,尽可能继续传输(resume)超出COT结束位置的PDSCH。
在一可能的实施方式中,位于COT结束位置之前的PDSCH不包括跨区PDSCH中位于COT结束位置之前的部分,其中,跨区PDSCH的起始时域位置位于COT结束位置之前,跨区PDSCH的结束时域位置位于COT结束位置之后。
在一示例中,1个DCI调度4个PDSCH,此4个PDSCH包括:PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4。其中,PDSCH 1、PDSCH 2完全位于COT结束位置之前,PDSCH4完全位于COT结束位置之后。PDSCH 3为跨区PDSCH,即PDSCH 3包括第一部分和第二部分,第一部分位于COT结束位置之前,第二部分位于COT结束位置之后。
本示例中,位于COT结束位置之前的PDSCH不包括PDSCH 3的第一部分。用户设备101在以第一方式或第二方式接收PDSCH时,接收的PDSCH只包括:PDSCH 1和 PDSCH 2,不包括PDSCH 3的第一部分。
在一可能的实施方式中,位于COT结束位置之前的PDSCH包括跨区PDSCH中位于COT结束位置之前的部分,其中,跨区PDSCH的起始时域位置位于COT结束位置之前,跨区PDSCH的结束时域位置位于COT结束位置之后。
在一示例中,1个DCI调度4个PDSCH,分别为PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4。其中,PDSCH 1、PDSCH 2完全位于COT结束位置之前,PDSCH 4完全位于COT结束位置之后。PDSCH 3为跨区PDSCH,即PDSCH 3包括第一部分和第二部分,第一部分位于COT结束位置之前,第二部分位于COT结束位置之后。
本示例中,用户设备101在以第一方式或第二方式接收PDSCH时,接收的PDSCH包括:PDSCH 1、PDSCH 2以及PDSCH 3的第一部分。
在一可能的实施方式中,位于COT结束位置之后的PDSCH除了包括COT结束位置之后的非跨区PDSCH外还包括跨区PDSCH中位于COT结束位置之后的部分,其中,跨区PDSCH的起始时域位置位于COT结束位置之前,跨区PDSCH的结束时域位置位于COT结束位置之后。
在一示例中,1个DCI调度4个PDSCH,分别为PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4。其中,PDSCH 1、PDSCH 2完全位于COT结束位置之前,PDSCH 4完全位于COT结束位置之后。PDSCH 3为跨区PDSCH,即PDSCH 3包括第一部分和第二部分,第一部分位于COT结束位置之前,第二部分位于COT结束位置之后。
本示例中,位于COT结束位置之后的PDSCH包括:PDSCH 3的第二部分以及PDSCH 4。
本公开实施例提供了一种接收物理下行共享信道的方法,此方法被用户设备101执行。此方法中包括步骤S1-1、步骤S1-2及步骤S1-3。其中,步骤S1-1中用户设备101确定物理下行共享信道PDSCH接收方式,可以包括:
基于协议的规定确定PDSCH接收方式。
本公开实施例提供了一种接收物理下行共享信道的方法,此方法被用户设备101执行。此方法中包括步骤S1-1、步骤S1-2及步骤S1-3。其中,步骤S1-1中用户设备101确定物理下行共享信道PDSCH接收方式,可以包括:
从网络设备102接收第一指示信息,其中,第一指示信息用于指示PDSCH接收方式 是第一方式或第二方式。
本公开中,根据协议规定或者网络设备102的指示,可以定义用户设备101的默认接收方式。
在一示例中,用户设备101的默认接收方式为第一方式。当存在PDSCH超出COT结束位置的场景时,用户设备101默认通过第一方式接收PDSCH。
在另一示例中,用户设备101的默认接收方式为第二方式。当存在PDSCH超出COT结束位置的场景时,用户设备101默认通过第二方式接收PDSCH。
本公开实施例提供了一种接收物理下行共享信道的方法,此方法被用户设备101执行。此方法中包括步骤S1-1、步骤S1-2及步骤S1-3,并且还包括:
根据最后一个PDSCH的时域位置确定用于发送HARQ反馈信息的物理上行控制信道PUCCH的资源,最后一个PDSCH包括:未接收的位于COT结束位置之后的最后一个PDSCH。
在一些可能的实施方式中,用户设备101根据最后一个PDSCH的时域位置,以及DCI中的K1值(表征PDSCH和PUCCH之间的时隙间隔)来确定HARQ-ACK PUCCH的时隙位置,并向网络设备102反馈该DCI所调度的PDSCH的HARQ-ACK信息。
比如,最后一个PDSCH的时域位置为时隙n,DCI中的K1值为k,则HARQ-ACK PUCCH的时隙位置为时隙n+k1。
在一示例中,1个DCI调度4个PDSCH,此4个PDSCH包括:PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4。其中,PDSCH 1、PDSCH 2完全位于COT结束位置之前,PDSCH 4完全位于COT结束位置之后。PDSCH 3为跨区PDSCH,即PDSCH 3包括第一部分和第二部分,第一部分位于COT结束位置之前,第二部分位于COT结束位置之后。
本示例中,最后一个PDSCH是指PDSCH 4。
若PDSCH 4的时隙位置为n,DCI中的K1=1,则HARQ-ACK PUCCH的时隙位置为n+1。
本公开的实施方式中,不仅适用于用户设备101监听并接收下行控制信息DCI2-0(含COT结束位置的指示信息)的场景;还适用于网络设备102为用户设备101配置并发送了下行控制信息DCI2-0,但用户设备101因为各种原因(例如信道深度衰落的原因)未成功收到DCI2-0的场景,即使最后一个PDSCH(如PDSCH 4)并未发送。
本公开实施例提供了一种接收物理下行共享信道的方法,此方法被用户设备101执行。此方法中包括步骤S1-1、步骤S1-2及步骤S1-3,并且还包括:
确定未接收的位于COT结束位置之后的各PDSCH所占用的相应的HARQ进程标识。
在一些可能的实施方式中,用户设备101可确定超出COT结束位置的PDSCH仍然占用相应的HARQ进程ID。若1个DCI调度多个PDSCH,则DCI中包含的HARQ进程标识(ID)指该DCI调度的第一个PDSCH的HARQ进程ID,对于后续PDSCH的HARQ进程ID可顺序加1。
在一个示例中,1个DCI调度4个PDSCH,分别为PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4。其中,PDSCH 1、PDSCH 2完全位于COT结束位置之前,PDSCH 4完全位于COT结束位置之后。PDSCH 3为跨区PDSCH,即PDSCH 3包括第一部分和第二部分,第一部分位于COT结束位置之前,第二部分位于COT结束位置之后。
若PDSCH 1的HARQ进程ID为i,则PDSCH 2的HARQ进程ID为i+1,PDSCH 3的HARQ进程ID为i+2,PDSCH 4的HARQ进程ID为i+3。
由此,本示例中,用户设备101可以确定未接收的PDSCH(如PDSCH 4)占用的HARQ进程标识。
本公开的实施方式中,不仅适用于用户设备101监听并接收下行控制信息DCI2-0(含COT结束位置的指示信息)的场景,还适用于网络设备102为用户设备101配置并发送了下行控制信息DCI2-0,但用户设备101因为各种原因(例如信道深度衰落的原因)未成功收到DCI2-0的场景,即超出COT结束位置的PDSCH(如PDSCH 4)仍占用相应的HARQ进程ID,即使最后一个PDSCH(如PDSCH 4)并未发送的场景。
本公开实施例提供了一种发送物理下行共享信道的方法,此方法被网络设备102执行。此方法中包括:
步骤S2-1、向用户设备101发送第一指示信息,其中,第一指示信息用于指示物理下行共享信道PDSCH接收方式是第一方式,或,PDSCH接收方式是第二方式。
步骤S2-2、向用户设备101发送下行控制信息;其中,下行控制信息包括用于指示COT结束位置的信息。
步骤S2-3、向用户设备101发送PDSCH。
其中,第一方式对应于用户设备101监听到包括COT结束位置的控制指示信息后, 接收位于COT结束位置之前的PDSCH,并且不接收位于COT结束位置之后的PDSCH;
第二方式对应于用户设备101监听到包括COT结束位置的控制指示信息后,接收位于COT结束位置之前的PDSCH,并且接收COT结束位置之后的PDSCH。
在一些可能的实施方式中,网络设备102为用户设备101配置的下行控制信息可记为DCI2-0。在DCI2-0中包含指示COT结束位置的信息。在DCI2-0中指示COT结束位置的信息的方式,可以是通过COT持续时长(duration)显示指示的方式,还可以是通过DCI2-0中时隙格式指示(SFI)为隐式指示的方式。
当网络设备102不配置DCI2-0时,用户设备101可能无法获知COT的结束位置,此时用户设备101可按照DCI的指示接收多个PDSCH,不考虑是否超出COT结束位置。
结合第一方式、第二方式以及网络设备102不配置DCI2-0的方式中,网络设备102可能存在未实际发送PDSCH的情况。在本公开中的实施方式中,网络设备102对于没有成功发出的PDSCH,可以通过DCI携带的信息指示用户设备101无效接收的PDSCH。比如,通过DCI2-1中抢占指示(Pre-emption Indicator,PI)指示用户设备101哪部分PDSCH接收是无效的。
在一些可能的实施方式中,网络设备102为用户设备101配置并发送了下行控制信息DCI2-0,但用户设备101因为各种原因(例如信道深度衰落的原因)未成功收到DCI2-0。此时,用户设备101仍根据最后一个PDSCH的时域位置确定用于发送HARQ反馈信息的物理上行控制信道PUCCH的资源,最后一个PDSCH包括:未接收的位于COT结束位置之后的最后一个PDSCH。用户设备101还可以确定未接收的位于COT结束位置之后的各PDSCH所占用的相应的HARQ进程标识。
