然而在一个DCI调度多个成员载波(Component Carrier,CC)的情况下,现有的设计将无法明确对应的传输或反馈资源。并且在高频段下,随着子载波间隔(Subcarrier Spacing,SCS)的增大符号会变短,现有的设计可能无法保证用户有足够的处理时间。
发明内容
本发明实施例提供一种资源确定方法及设备,以解决现有的设计无法明确传输资源的问题。
为了解决上述技术问题,本发明是这样实现的:
第一方面,本发明的实施例提供了一种资源确定方法,包括:
获取目标资源的一个或多个参考点的指示信息;
根据所述指示信息,确定所述目标资源。
第二方面,本发明的实施例还提供了一种用户侧设备,包括:
获取模块,用于获取目标资源的一个或多个参考点的指示信息;
确定模块,用于根据所述指示信息,确定所述目标资源。
第三方面,本发明实施例还提供了一种用户侧设备,包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序,所述计算机程序被所述处理器执行时实现如上所述的资源确定方法的步骤。
第四方面,本发明实施例还提供了一种计算机可读存储介质,所述计算机可读存储介质上存储有计算机程序,所述计算机程序被处理器执行时实现如上所述的资源确定方法的步骤。
第五方面,本发明实施例还提供了一种计算机软件产品,所述计算机软件产品被存储在非易失的存储介质中,所述软件产品被配置成被至少一个处理器执行以实现如上所述的资源确定方法的步骤。
这样,本发明实施例中,首先获取指示信息,因该指示信息是针对目标资源,指示该目标资源的一个或多个参考点的信息,之后就能够由该指示信息明确出传输使用的目标资源,避免了无法明确传输资源的情况,保证了传输的实现。

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。为了方面描述,下文‘/’符号等同于或者。
本发明实施例的方法应用于用户侧设备,该用户侧设备(user equipment,UE)可以指接入终端、用户单元、用户站、移动站、移动台、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、个人数字助理(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。
如图1所示,本发明实施例的一种资源确定方法,包括:
步骤101,获取目标资源的一个或多个参考点的指示信息。
这里,参考点用于确定目标资源,该目标资源可以是数据资源和/或反馈资源;而指示信息用于指示一个或多个参考点。本步骤中,通过获取该指示信息,从而能够在下一步骤中完成目标资源的确定。
步骤102,根据所述指示信息,确定所述目标资源。
本步骤中,在步骤101获取到的指示信息之后,能够由该指示信息指示的一个或多个参考点,最终确定传输使用的目标资源。
因此,按照步骤101和步骤102,本发明实施例的资源确定方法,首先获取指示信息,因该指示信息是针对目标资源,指示该目标资源的一个或多个参考点的信息,之后就能够由该指示信息明确出传输使用的目标资源,避免了无法明确传输资源的情况,保证了传输的实现。
其中,指示资源分配的信令可携带该指示信息,也可以不携带该指示信息。
具体的,本发明实施例的方法可应用于数据传输和/或反馈传输。对于数据传输,用户侧设备在获取到一个或多个参考点的指示信息后,由该指示信息指示的对应参考点,就能够确定数据传输使用的数据资源,如物理下行共享信道(Physical Downlink Shared Channel,PDSCH)和/或物理上行共享信道(Physical Uplink Shared Channel,PUSCH);对于反馈传输,用户侧设备在获取到一个或多个参考点的指示信息后,由该指示信息指示的对应参考点,就能够确定反馈传输使用的反馈资源,如PUSCH。
可选地,步骤101包括以下至少一种方式:
通过高层信令;
通过预定义;
通过控制信令。
如此,若基站通过高层信令(如,无线资源控制(Radio Resource Control,RRC))配置目标资源的一个或多个参考点,则UE可通过接收高层信令获取到该指示信息。或者,基站或UE通过预定义(如协议定义或用户自定义)获取到该指示信息。又或者,UE通过接收控制信令(如RRC、媒体接入控制层控制单元(Medium Access Control Control Element,MAC CE),其他高层信令和DCI中的至少一个)获取到该指示信息。其中,DCI可以是调度N个CC的联合调度DCI即joint DCI,或者,可以是单调度DCI即single DCI。该实施例的方法可以用于低频段,也可以用于高频段。例如该实施例的方法可以用于动态频谱共享(Dynamic Spectrum Sharing,DSS)频段或LTE refarming频段或FR1或未授权频段,也可以用于FR2频段或FR3频段或者52.6GHz以上的频段。
当然,也可通过高层信令、预定义和控制信令中至少两者的联合指示,获取到确定目标资源所需的指示信息。例如,由高层信令或预定义的指示信息可得到参考点的第一集合,而通过控制信令可进一步得到该第一集合中的一个或多个参考点来确定目标资源;或者,先后接收不同信令(如高层信令和控制信令,或,第一控制信令和第二控制信令),可由多条信令联合确定目标资源的参考点,或者根据信令时间先后确定目标资源的参考点,或者根据指示信息的优先级得到用于确定目标资源的参考点。
例如多条信令联合得到用于确定目标资源的参考点的一种方式是根据收到的多条信令指示的内容联合确定目标资源所需的指示信息。例如先收到RRC信令指示参考点周期,再收到DCI指示了参考点的时域偏移,从而获取到确定目标资源所需的参考点。例如先收到某条信令指示参考点所在时域资源的指示标识,再收到另一条信令指示了参考点标识,从而获取到确定目标资源所需的参考点为该时域资源指示标识对应时域资源上对应该参考点标识的参考点。
例如按照时间先后得到用于确定目标资源的参考点的一种方式是根据不 同时间收到的信令逐步确定目标资源所需的指示信息。例如先收到RRC信令指示参考点集合,再收到DCI指示了该参考点集合中的某个参考点,从而获取到确定目标资源所需的参考点。
例如按照指示信息的优先级得到用于确定目标资源的参考点的一种方式是优先级高的信令指示的至少部分内容会覆盖或者替代优先级低的信令指示的对应内容。例如假设RRC信令优先级低于第一控制信令,则收到RRC指示参考点或参考点某个属性,又收到第一控制信令指示了不同参考点或不同的参考点属性,则用户基于第一控制信令确定目标资源所需的参考点;又假设RRC信令优先级低于第一控制信令,第一控制信令优先级低于第二控制信令,若用户收到了RRC信令但是没有收到过第一控制信令和第二控制信令,则用户根据RRC信令确定目标资源所需的参考点.若用户收到了RRC信令和第一控制信令但是没有收到过第二控制信令,则用户根据第一控制信令确定目标资源所需的参考点.若用户收到了RRC信令和第一控制信令和第二控制信令,则用户根据第二控制信令确定目标资源所需的参考点。

而准共址(Quasi co-location,QCL)参考包括了下行传输的传输配置指示(Transmission Configuration Indication,TCI)state中指示的RS和/或上行传输的QCL参考。例如,对应PDCCH的TCI state的RS为某个SSB,则以该SSB的时域位置为第一位置;对应PDCCH的TCI state的RS为某个CSI-RS,则以该CSI-RS的时域位置为第一位置;对应数据的TCI state中的RS为某个SSB,则以该SSB的时域位置为第一位置;对应数据的TCI state中的RS为某个CSI-RS,则以该CSI-RS的时域位置为第一位置。

其中,所述参考点位图中至少部分比特与第一参考点集合中的至少部分参考点对应;和/或,

所述第一参考点集合为通过高层信令、预定义和控制信令中的至少一种确定的参考点的集合。
其中,第一参考点集合中参考点的编号表示参考点在第一参考点集合的位置或者顺序。或者,参考点编号为参考点在预设数量的参考点中的编号,如位置或顺序。可选地,该预设数量可以是指示信息指示的最大参考点数目。该最大参考点数目可以是指示信息指示的,也可以是其他信息指示或配置的,又或者是协议规定的等等。
当然,该指示信息还可以包括参考点的周期,参考点相对于第一位置的时间偏移值,参考点所在的时域资源的指示标识和参考点标识中的至少一个。
例如,通过高层信令配置和/或预定义的第一指示信息可得到C个参考点,该第一指示信息可包括参考点相对于第一位置的时间偏移值、参考点的周期、参考点所在的时域资源的指示标识和参考点标识中的至少一个。通过第一控制信令的第二指示信息可得到D个参考点,该第二指示信息可包括参考点相对于第一位置的时间偏移值、参考点的周期、参考点所在的时域资源的指示标识、参考点标识、参考点位图和参考点编号中的至少一个。其中,若该第二指示信息包括对应C个参考点的参考点位图,则通过该参考点位图得到的D个参考点属于C个参考点中。若第二指示信息包括对应C个参考点的参考点编号,则通过该参考点编号得到的D个参考点属于C个参考点中。当然,该第二指示信息中参考点相对于第一位置的时间偏移值可以是第一指示信息中参考点相对于第一位置的时间偏移值的至少一个,或者,该第二指示信息中参考点周期可以是第一指示信息中参考点周期的至少一个,或者,该第二指示信息中参考点所在的时域资源的指示标识可以是第一指示信息中参考点所 在的时域资源的指示标识的至少一个,或者,该第二指示信息中参考点标识可以是第一指示信息中参考点标识的至少一个,以在C个参考点中进一步得到D个参考点。若C为8的倍数,如第一指示信息对应的C=64,则第二指示信息对应的D=8或者D=1。

对于指示信息包括第四信息,若该第四信息指示使用与当前指示信息类型不同的指示信息指示的参考点,则会基于指示信息类型,使用不同于当前指示信息类型的其它指示信息指示的参考点。例如在当前的指示信息类型为MAC CE时,后续将不再以MAC CE指示参考点,而是采用RRC或DCI或其他高层信令等方式指示的参考点。
若该第四信息指示不需要传输或者不存在传输资源,则是在目标资源为数据资源(如PUSCH或PDSCH)的情况下,不需要传输数据资源或者不存在数据资源。
若该第四信息指示不需要反馈或者不存在反馈资源,则是在目标资源为用于反馈信息的反馈资源(如PUCCH或PUSCH)的情况下,不需要反馈或者不存在反馈资源。又例如目标资源为数据资源(PUSCH或PDSCH)时,第四信息意味着不需要反馈或者不存在反馈资源。
当然,该实施例中,目标资源可能有一个或者多个。对于多个目标资源的情况,第四信息指示的不传输或不反馈是该多个目标资源中的至少一个,或者,至少一个目标资源不存在。优选地,取消全部目标资源或者全部目标资源都不存在。例如一个DCI调度了两个PDSCH,且该DCI指示参考点的域中为指示信息,该指示信息包括第四信息,则此时两个PDSCH都不传输或者两个PDSCH都不需要用户反馈。
可选地,本发明实施例中反馈信息可以是HARQ反馈信息,CSI报告,RS测量结果(例如RSRP、RSRQ、RSSI的至少一项),被请求的CSI-RS,被请求的SRS等中的至少一项。

该实施例中,为保证充足的处理时间,目标参考点可为对应的反馈资源和数据资源之间的间隔大于处理时延的参考点。例如,2个参考点中,对应参考点1确定的反馈资源在slot x1,对应参考点2确定的反馈资源在slot x2,而x1与被调度的数据资源之间的时间间隔是n1,与被调度的数据资源之间的时间间隔是n2,其中n1小于处理时延要求N1,n2大于处理时延要求N1,则参考点2将作为目标参考点。当然,可选地,若多个参考点对应的反馈资源和数据资源之间的间隔均大于处理时延要求N1,则会在其中选择间隔最大或最小的参考点作为目标参考点。例如n1、n2均大于处理时延,且n1大于 n2,可将间隔最大的参考点1将作为目标参考点;或者,将间隔最小的参考点2作为目标,从而降低时延。
当然,目标参考点也可为多个参考点中,满足第一HARQ编号的参考点,可选地,所述第一HARQ编号包括以下至少一项:
传输对应的HARQ编号;
所述目标资源对应的HARQ编号;
所述指示信息指示或配置的HARQ编号;
所述下行控制信息指示或配置的HARQ编号。
如此,在多个参考点中,可基于参考点与HARQ编号的对应关系进行指示。如,参考点位置除以周期P等于目标资源对应的HARQ进程号H,该参考点确定的目标资源可以用于传输对应HARQ进程号H的信息。可选地,对(参考点/P)的结果向上或向下取整后得到H,此时该参考点确定的反馈资源可以用于传输对应HARQ进程号H的反馈信息。又或者,根据需要反馈信息的传输的HARQ编号指定参考点,例如UE需要反馈HARQ编号=1对应的传输的HARQ-ACK信息,则选择和HARQ编号=1对应的参考点用于确定反馈资源。
该实施例中,在确定目标参考点之后,可选地,步骤102还包括:
根据所述目标参考点和时间间隔K’,得到所述目标资源。
这里,时间间隔可通过DCI指示或RRC配置。而目标资源可为目标参考点+时间间隔。例如,目标参考点位于slot2,时间间隔K’=2slot,则目标资源位于slot4。
另外,可选地,该实施例中,步骤102之后,还包括:
传输目标资源。
当然,该目标资源可以是数据资源,通过该目标资源进行数据的传输;该目标资源也可以是反馈资源,通过该目标资源进行反馈信息的传输。其中,可选地,对于反馈信息的传输,与该目标资源对应的目标参考点和与该反馈信息对应的混合自动重传请求进程号具有对应关系。
优选地,该实施例中,若配置或预定义或指示一个参考点,则多个被调度小区的反馈信息可在相同的时域资源或者相同的反馈资源上反馈;若用户 确定一个参考点,则多个被调度小区的反馈信息在相同的时域资源或者相同的反馈资源上反馈。
下面结合具体场景说明本发明实施例的方法的应用:
场景一、协议定义参考点为joint DCI所在时域资源。如图2所示,该joint DCI调度2个CC,分为30kHz和15kHz,PUCCH位于CC1上且PUCCH SCS为30kHz。Slot n上的joint DCI指示K1=4,则两个CC上被调度的两个PDSCH对应的HARQ-ACK在Slot n+4上反馈。
场景二、第一位置为joint DCI所在时域资源,高层信令配置参考点相对于第一位置的时间偏移值time offset,且time offset=0。如图2所示,该joint DCI调度2个CC,分为30kHz和15kHz,PUCCH位于CC1上且PUCCH SCS为30kHz。Slot n上的joint DCI指示K1=4,则两个CC上被调度的两个PDSCH对应的混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)在Slot n+4上反馈。
场景三、第一位置为joint DCI所在时域资源。如图2所示,该joint DCI调度2个CC,分为30kHz和15kHz,PUCCH位于CC1上且PUCCH SCS为30kHz。Slot n上的joint DCI指示K1=4且指示参考点相对于第一位置的time offset,且time offset=0,则两个CC上被调度的两个PDSCH对应的HARQ-ACK在Slot n+4上反馈。
场景四、RRC配置参考点列表,该参考点列表包含C个参考点时域资源的指示标识,C=8*N,如图3所示。第一控制信令中包含了长度L的参考点位图,L个bit中的C个bit和C个参考点时域资源的指示标识一一对应,C个bit中D个bit的值指示了其对应的参考点被使用,当然C个bit中D个bit的值也可表示其对应的参考点被指示。若L=C,则L个bit中有D个bit的值指示了该参考点被使用。
例如bit=1时表示参考点被使用或被指示,若D=8则有8个bit=1,其对应的参考点被使用或被指示;或者反过来,例如bit=0时表示参考点被使用或被指示,若D=8则有8个bit=0,其对应的参考点被使用或被指示。
进一步可选地,第一控制信令还携带了对应的小区标识和BWP标识,如图4。
可选地,若D=1,则UE使用该参考点用于确定反馈资源。
可选地,UE获取了第二控制信令,第二控制信令指示了上述第一控制信令指示的D个参考点中某个参考点的编号(该编号可以是该参考点在C个参考点中的编号,也可以是在D个参考点中的相对编号),该参考点用于确定反馈资源。优选地,第一控制信令为MAC CE,第二控制信令为DCI。
例如高层配置了参考点1-64,第一控制信令指示了参考点1,2,4,5,7,8,16,20。第二控制信令可能指示了编号4,则该第二控制信令一种实现为,指示参考点4;一种实现为,指示{参考点1,2,4,5,7,8,16,20}中的第4个参考点,即参考点5,两种实现都可以工作。
以第二控制信令指示为参考点5为例,参考点5为slot n。假设第二控制信令joint DCI调度2个CC,分为30kHz和15kHz,如图2所示,PUCCH位于CC1上且PUCCH SCS为30kHz。该joint DCI指示K1=4,则两个CC上被调度的两个PDSCH对应的HARQ-ACK在slot n+4上反馈。
场景五、第一控制信令为MAC CE,且指示参考点。
若第一控制信令指示一个参考点,则第一控制信令可设计如图5,其中,R为预留域,可能占据0bit;剩余域为指示信息域,携带一个参考点的指示信息。如此,高层信令配置了参考点1-64,第一控制信令的指示信息指示了参考点5。
若第一控制信令指示多个参考点,假设每个参考点的指示信息占据8bit,则第一控制信令可设计如图6。如此,高层信令配置了参考点1-64,第一控制信令的指示信息指示了参考点6、7、8。
进一步的,第一控制信令还可能携带BWP标识和/或小区标识。
场景六、第一控制信令为joint DCI,且指示参考点的编号,如编号5,而高层配置了参考点1-64。假设参考点5为slot n,第一控制信令Joint DCI调度2个CC,分为30kHz和15kHz,如图2所示,PUCCH位于CC1上且PUCCH SCS为30kHz。该joint DCI指示K1=4,则两个CC上被调度的两个PDSCH对应的HARQ-ACK在slot n+4上反馈。
综上所述,本发明实施例的方法,首先获取指示信息,因该指示信息是针对目标资源,指示该目标资源的一个或多个参考点的信息,之后就能够由 该指示信息明确出传输使用的目标资源,避免了无法明确传输资源的情况,保证了传输的实现。
