Description
本公开涉及通信技术领域,尤其涉及一种通信方法、通信装置及存储介质。
新一代的新型互联网应用的不断涌现对于无线通信技术提出了更高的要求,驱使无线通信技术的不断演进以满足应用的需求。设备节能是无线通信技术研究的多个热点之一。
Rel-16中一种用户设备节能方法是通过跨时隙(cross-slot)调度。网络设备可以为用户设备(User Equipment,UE)配置最多两个最小k0值。其中,最小k0值可以理解为是下行的物理下行控制信道(Physical Downlink Control Channel,PDCCH)传输所在的时隙(slot)和其调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输所在的slot之间的最小slot间隔。当k0=0时,下行PDSCH传输和对应的下行PDCCH调度为同slot调度。当最小k0值被设置为大于等于1时,下行PDSCH传输和对应的下行PDCCH调度会在不同的slot里传输。大部分时候用户设备没有下行数据调度,可以有效减少用户设备下行监听的能耗,但是会造成下行数据传输的延迟。
XR(扩展现实)业务是变速率周期性业务,每个周期的数据大小可能变化很大,并且对时延也有较高的要求。对于XR设备而言,如果为了节能把k0最小值设为大于或等于1的值,会造成XR业务延时的增加。因此无法直接使用Rel-16的cross slot调度节能方案。并且,相关技术中支持使用下行控制信息(Downlink control information,DCI)进行最小K0值的切换,但是由于XR业务周期变化较大,故进行K0值切换的DCI也会增多,使用DCI进行切换信令开销大,效率低。

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。
本公开实施例提供的通信方法可应用于图1所示的无线通信***中。参阅图1所示, 该无线通信***中包括用户设备(User Equipment,UE)和网络设备。用户设备通过无线资源与网络设备相连接,并进行数据的发送与接收。
可以理解的是,图1所示的无线通信***仅是进行示意性说明,无线通信***中还可包括其它网络设备,例如还可以包括核心网设备、无线中继设备和无线回传设备等,在图1中未画出。本公开实施例对该无线通信***中包括的网络设备数量和用户设备数量不做限定。
进一步可以理解的是,本公开实施例的无线通信***,是一种提供无线通信功能的网络。无线通信***可以采用不同的通信技术,例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access,WCDMA)、时分多址(time division multiple access,TDMA)、频分多址(frequency division multiple access,FDMA)、正交频分多址(orthogonal frequency-division multiple access,OFDMA)、单载波频分多址(single Carrier FDMA,SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文:generation)网络、3G网络、4G网络或者未来演进网络,如5G网络,5G网络也可称为是新无线网络(New Radio,NR)。为了方便描述,本公开有时会将无线通信网络简称为网络。
进一步的,本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是:基站、演进型基站(evolved node B,基站)、家庭基站、无线保真(wireless fidelity,WIFI)***中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为NR***中的gNB,或者,还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信***时,网络设备还可以是车载设备。应理解,本公开的实施例中,对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的,本公开中涉及的用户设备,也可以称为终端设备、终端、移动台(Mobile Station,MS)、移动终端(Mobile Terminal,MT)等,是一种向用户提供语音和/或数据连通性的设备,例如,终端可以是具有无线连接功能的手持式设备、车载设备等。目前,一些终端的举例为:智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer,PPC)、掌上电脑、个人数字助理(Personal Digital Assistant,PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外,当为车联网(V2X)通信***时,终端设备还可以是车载设备。应理解,本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
用户设备节能成为无线通信技术研究的热点。相关技术中,采用cross-slot调度。网络 设备可以为用户设备配置最多两个最小k0值。最小k0值规定了网络设备下行的PDCCH传输所在的slot和其调度的PDSCH传输所在的slot之间的最小slot间隔。当k0=0时,为同slot调度。当最小k0值被设置为大于等于1的时候,下行PDSCH传输和对应的下行PDCCH调度会在不同的slot里传输。对于一个下行slot,用户设备可以监听PDCCH可能出现的CORESET所在的2或3个symbol。由于大部分时候用户没有下行数据调度,可以有效减少用户下行监听的能耗,但是会造成下行数据传输的延迟。
然而,随着通信技术的发展,各种变速率周期性业务出现,例如XR业务。变速率周期性业务,每个周期的数据大小可能变化很大,不适用于CG传输,需要使用DCI进行动态调度。对于变速率周期性业务(例如XR业务)来说,设备尺寸重量受限制(如AR眼镜),对于节能的要求也很高。同时,变速率周期性业务(例如XR业务)对于延时也有很高的要求。如果为了节能,采用上述cross slot调度节能方案,把k0最小值设为大于或等于1的值,会造成变速率周期性业务(例如XR业务)延时的增加。因此,无法直接使用Rel-16的cross slot调度节能方案。
进一步的,相关技术中支持使用DCI进行最小K0值切换,但是切换后的K0值需要在接收到携带切换指令的DCI之后一段时间后生效,但是变速率周期性业务(例如XR业务)的周期可能是几毫秒到几十毫秒,使用DCI进行切换,信令开销大,并且通信效率低。
有鉴于此,本公开实施例提供一种通信方法,在该通信方法中,针对指定时频资源范围内接收的PDCCH应用指定最小调度偏移值,以降低信令开销,提高通信效率。
本公开实施例中为描述方便,将上述指定时频资源范围称为第一时频资源范围,将指定时频资源范围内接收的PDCCH应用的指定最小调度偏移值称为第一最小调度偏移值。
图2是根据一示例性实施例示出的一种通信方法的流程图,如图2所示,通信方法应用于用户设备中,包括以下步骤。
在步骤S11中,确定第一时频资源范围。
本公开实施例中,第一时频资源范围可以是用户设备可以基于协议确定,或者基于出厂配置、或者基于网络环境、信号强度等等进行自主判断确定。其中,本公开实施例中第一时频资源范围可以是变速率周期性业务调度使用的时频资源范围。
进一步的,本公开实施例中涉及的时频资源可以理解为是时间资源、频率资源、或时间与频率资源。
一种实施方式中,用户设备可以接收来自网络设备发送的下行控制信令,所述下行控制信令指示所述第一时频资源范围。第一时频资源范围可以是根据网络设备发送的下行控制信令确定的。其中,该下行控制信令可以是物理层信令,也可以是无线资源控制(Radio Resource Control,RRC)信令,或者也可以是媒体接入控制(Media Access Control,MAC)信令。
在步骤S12中,针对在第一时频资源范围内的PDCCH,确定与第一时频资源范围相关联的第一最小调度偏移值。
其中,第一最小调度偏移值指示PDCCH传输与由PDCCH传输调度的物理信道传输之间的时域偏移的最小值。其中,PDCCH传输调度可以理解为是调度信息由PDCCH承载的DCI携带。
本公开实施例中第一最小调度偏移值是与第一时频资源范围相关联的,也可以理解为是第一最小调度偏移值是专为第一时频资源范围配置的。
本公开实施例中,第一最小调度偏移值可以是预定义的默认值。例如,第一最小调度偏移值可以是基于通信协议设置的默认值,也可以是出厂设置的默认值。或者,第一最小调度偏移值也可以是用户设备基于网络环境、基于当前运行的app的参数等自主确定的。或者第一最小调度偏移值是基于来自网络设备发送的下行控制信令确定的。其中,该下行控制信令可以是物理层信令,也可以是无线资源控制(Radio Resource Control,RRC)信令,或者也可以是媒体接入控制(Media Access Control,MAC)信令。
本公开实施例中,第一最小调度偏移值包括最小K0值,K0值可以理解为是PDCCH和PDCCH所调度的PDSCH传输之间的时隙偏移值。或者第一最小调度偏移值包括最小K2值,K2值为PDCCH和PDCCH所调度的PUSCH传输之间的时隙偏移值。或者,第一最小调度偏移值包括最小K0值和最小K2值。
本公开实施例中,第一最小调度偏移值可以理解为是与第一时频资源范围相关联的。
其中,第一最小调度偏移值可以是隐式的与第一时频资源范围相关联,也可以是显式的与第一时频资源范围相关联。
一种实施方式中,第一最小调度偏移值隐式的与第一时频资源范围相关联可以理解为是网络设备向用户设备指示第一时频资源,而无需单独指示与第一时频资源关联的第一最小调度偏移值。或者网络设备向用户设备指示第一最小调度偏移值,而无需单独指示第一时频资源。用户设备可以通过例如下行控制信令的格式,特定的映射关系等,判断出下行控制信令所指示的第一时频资源。
一种实施方式中,第一最小调度偏移值显式的与第一时频资源范围相关联可以理解为是用户设备确定第一时频资源范围,以及与第一时频资源范围相关联的第一最小调度偏移值。
本公开实施例中,第一时频资源可以是基于网络设备发送的下行配置信息确定,或者 第一时频资源也可以是预定义的。第一最小调度偏移值可以是基于网络设备发送的下行配置信息确定,或者第一最小调度偏移值也可以是预定义的。
一种实施方式中,第一最小调度偏移值预定义的默认值为0。
第一时频资源范围内接收的PDCCH所应用的第一最小调度偏移值可以为0。其中,若第一最小调度偏移值为0可以理解为是没有为第一时频资源配置第一最小调度偏移值。在第一时频资源范围内接收的PDCCH不受第一最小调度偏移值的限制,或者第一时频资源范围内的PDCCH与PDCCH所调度的PDSCH传输之间的时间差不受第一最小调度偏移值的限制。一示例中,当没有配置最小K0的时候,默认最小K0=0,即不支持以节能为目的的cross slot调度。进一步的,K0是PDCCH和其调度的下行PDSCH传输之间的slot间隔,所以最小就是同slot调度,K2也类似。
可以理解的是,本公开实施例中,第一时频资源范围内接收的PDCCH受第一最小调度偏移值的限制,可以理解为是PDCCH与其调度的PDSCH之间的时域偏移K0值必需满足大于或等于最小K0值的要求。第一时频资源范围内接收的PDCCH不受第一最小调度偏移值的限制,可以理解为是PDCCH与其调度的PDSCH之间的时域偏移K0值无需满足大于或等于最小K0值的要求。
其中,PDCCH与其调度的PDSCH之间的时域偏移K0值可以是时域偏移K0值集合。
本公开实施例中,网络设备针对第一时频资源范围内,为用户设备调度PDCCH传输与由PDCCH传输调度的物理信道传输之间的时域偏移需要保证满足大于或等于最小K0值的要求。用户设备默认网络设备针对第一时频资源范围内为用户设备调度PDCCH传输与由PDCCH传输调度的物理信道传输之间的时域偏移大于或等于最小K0值。
本公开实施例中,一种实施方式中,第一时频资源可以是根据网络设备发送的下行配置信息确定的。另一种实施方式中,第一时频资源也可以是预定义的。
其中,本公开实施例一种实施方式中,第一时频资源可以是基于控制资源集(Control resource set,CORESET)确定的,用于盲检PDCCH的时频资源。第一时频资源也可以是基于搜索空间(search space,SS)确定的,用于盲检PDCCH的时频资源。
其中,本公开实施例中将用于确定第一时频资源的控制资源集称为第一控制资源集,将用于确定第一时频资源的搜索空间称为第一搜索空间。其中,第一搜索空间可以是搜索空间集合。即,本公开实施例中第一时频资源可以是基于第一控制资源集和/或第一搜索空间确定、并用于盲检PDCCH的时频资源。
其中,用户设备可以接收网络设备发送的下行控制信令,并基于该下行控制信令确定第一控制资源集和/或第一搜索空间。
一示例中,网络设备可以通过下行控制信令为用户设备指示特定的用于用户下行数据调度PDCCH监听的search space(SS-搜索空间)或SS集合。
如果用户设备被配置了最小K0值和/或最小K2值,被指定的SS上的PDCCH与其调度的PDSCH之间的时间差不受最小K0值的限制,和/或指定的SS上的PDCCH与其调度的PDCCH之间的时间差不受最小K2值的限制。如果对于被指定的SS,用户设备按照没有被配置最小K0值进行PDCCH监听,即不进行cross-slot调度节能优化。
另一示例中,网络设备可以通过下行控制信令为用户设备指示特定的用于用户下行数据调度PDCCH监听的search space(SS-搜索空间)或SS集合,并指示与所述SS或SS集合相关联的最小K0值和/或最小K2值。对于被指定的SS上的PDCCH调度受到其所关联的最小K0值和/或最小K2值限制。对于被指定的SS,用户设备按照其所关联的最小K0值和/或最小K2值限制进行PDCCH监听。
本公开实施例另一种实施方式中,第一时频资源可以是指定时间窗(以下称为第一时间窗)内的时频资源。
其中,用户设备可以接收网络设备发送的下行控制信令,并基于该下行控制信令确定第一时间窗内的时频资源。
本公开实施例中,第一时间窗可以是周期性的。
一示例中,网络设备可以通过下行控制信令为用户设备配置第一时间窗。如果用户设备被配置了最小K0值和/或最小K2值,在第一时间窗内的PDCCH与其调度的PDSCH之间的时间间隔不受最小K0值的限制,和/或第一时间窗内的PDCCH与其调度的PDCCH之间的时间差不受最小K2值的限制。用户设备按照未配置最小K0值和/或最小K2值进行PDCCH监听。
另一示例中,网络设备可以通过下行控制信令为用户设备配置第一时间窗,并配置与第一时间窗关联的最小K0值和/或最小K2值。在第一时间窗内的PDCCH与其调度的PDSCH之间的时间间隔受所关联的最小K0值的限制。用户设备按照所关联的最小K0值和/或最小K2值进行PDCCH监听。
以上,本公开实施例中,第一控制资源集、第一搜索空间、或第一时间窗中的至少一项是基于来自网络设备发送的下行控制信令确定的。
本公开实施例中,用户设备被配置有不同于所述第一最小调度偏移值的第二最小调度偏移值,即第一时频资源可能还被配置有不同于第一最小调度偏移值的其他最小调度偏移值(以下称为第二最小调度偏移值)。此种情况下,本公开实施例中,可以基于所述第一最小调度偏移值和所述第二最小调度偏移值的优先级,应用所述第一最小调度偏移值,所 述第一最小调度偏移值的优先级高于所述第二最小调度偏移值的优先级。例如,基于最小调度偏移值优先级顺序,确定在所述第一时频资源范围内接收的PDCCH所应用的最小调度偏移值,其中,所述第一最小调度偏移值的优先级高于所述第二最小调度偏移值的优先级。
一示例中,网络设备通过下行控制信令为用户设备指示特定的用于用户下行数据调度PDCCH监听的search space(SS-搜索空间)或SS集合,并指示与所述SS或SS集合相关联的最小K0值和/或最小K2值。其中,该相关联有最小K0值和/或最小K2值的search space(SS-搜索空间)或SS集合,还被配置了其他的最小K0值和/或最小K2值(如Rel16最小K0配置方法,按照SCS大小配置最小K0值)。网络设备调度优先受到与该SS关联的最小K0值和/或最小K2值限制,用户设备优先按照该SS关联的最小K0值和/或最小K2值进行PDCCH监听。
另一示例中,网络设备通过下行控制信令为用户设备指示特定的时间窗,并配置与所述时间窗关联的最小K0值和/或最小K2值。其中,所述时间窗可以是周期性的。其中,该相关联有最小K0值和/或最小K2值的时间窗,还被配置了其他的最小K0值和/或最小K2值(如Rel16最小K0配置方法,按照SCS大小配置最小K0值)。网络设备调度优先受到与该时间窗关联的最小K0值和/或最小K2值限制,用户设备优先按照该时间窗关联的最小K0值和/或最小K2值进行PDCCH监听。
图3是根据一示例性实施例示出的一种通信方法的流程图,如图3所示,通信方法应用于网络设备中,包括以下步骤。
在步骤S21中,确定第一时频资源范围,第一时频资源范围关联有第一最小调度偏移值。
其中,所述第一最小调度偏移值指示所述PDCCH传输与由所述PDCCH传输调度的物理信道传输之间的时域偏移的最小值。
一种实施方式中,第一最小调度偏移值包括最小K0值和/或最小K2值。
K0值为PDCCH和PDCCH所调度的物理下行共享信道PDSCH传输之间的时隙偏移值。K2值为PDCCH和PDCCH所调度的物理上行共享信道PUSCH传输之间的时隙偏移值。
一种实施方式中,第一时频资源为基于第一控制资源集和/或第一搜索空间确定的、并用于盲检PDCCH的时频资源;或者,第一时频资源为第一时间窗内的时频资源。
一种实施方式中,本公开实施例中,网络设备还可以发送下行控制信令。通过该下行控制信令指示第一时频资源范围。
一种实施方式中,第一最小调度偏移值是预定义的默认值;或者,第一最小调度偏移值是用户设备确定并发送给所述网络设备的;或者第一最小调度偏移值是所述网络设备自主确定的。
其中,预定义的默认值为0。
第一时频资源为基于第一控制资源集和/或第一搜索空间确定的;或者,所述第一时频资源为第一时间窗内的时频资源。
一种实施方式中,网络设备可以发送下行控制信令。下行控制信令用于指示以下各项中的至少一项:所述第一控制资源集、所述第一搜索空间、或所述第一时间窗。
一种实施方式中,网络设备还可以发送下行配置信息,下行配置信息用于指示第一时频资源和/或第一最小调度偏移值。与第一时频资源相关联的第一最小调度偏移值基于网络设备发送的下行配置信息确定。
一种实施方式中,网络设备基于第一最小调度偏移值,针对第一时频资源范围,为用户设备调度PDCCH传输与由所述PDCCH传输调度的物理信道传输之间的时域偏移。
可以理解的是,本公开实施例中应用于网络设备的通信方法,是上述应用于用户设备的通信方法的对侧方法实现,故对于应用于网络设备发送的通信方法描述不够详尽的地方,可参阅上述实施例的相关描述。
本公开实施例提供的通信方法,也可以应用于网络设备与用户设备之间进行交互的实现流程中。在网络设备与用户设备交互实现上述涉及的通信方法中,网络设备和用户设备各自对应实现上述涉及的通信方法功能,在此不再详述。
本公开实施例提供的通信方法,针对第一时频资源应用关联的第一最小调度偏移值进行通信。针对可变速率的大流量准周期性数据传输的应用场景中,对于这些可变速率的大流量准周期性数据,由于其到达时间具有规律性,cross slot调度的节能收益较低,延时要求又比较高,可以按照较小的最小K0值和/或最小K2值(如K0=0)进行调度,即通时隙调度(intra-slot调度)。
本公开实施例中,如果K0=0,用户设备需要按照可能发生intra-slot调度进行接收,即在一个slot里除了进行PDCCH监听的OFDM时域符号,还需要接收并缓存之后所有的时域符号。如果检测到PDCCH的存在并且发生了同slot的调度,需要根据PDCCH的指示在正确的时频资源上解调出PDCCH所调度的PDSCH。如果没有检测到PDCCH的存在,或者没有针对本slot的调度,则丢弃缓存的信号。
其中,除了可变速率的大流量准周期性数据(例如XR业务),用户设备还存在其他业务的下行数据,或者一些XR业务中的延时性要求不高的下行数据。对于这些数据,其到 达没有很强的规律性,可以通过cross-slot调度进行节能。
如果用户设备配置的最小K0值,PDCCH和其调度的PDSCH不在一个slot。一个slot内,用户设备可以接收进行PDCCH监听和被之前slot的PDCCH调度的OFDM符号,节省不必要的接收造成的能量消耗。
综上,通过本公开实施例提供的通信方法,从节能角度考虑,希望同时支持一个用户设备对于部分业务的intra-slot调度和对于其他业务的inter-slot调度。
基于相同的构思,本公开实施例还提供一种通信装置。
可以理解的是,本公开实施例提供的通信装置为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤,本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能,但是这种实现不应认为超出本公开实施例的技术方案的范围。
