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所获得的所有其他实施例,都属于本申请保护的范围。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也称为用户设备(User Equipment,UE)可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(Ultra-mobile Personal Computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(Augmented Reality,AR)、虚拟现实(Virtual Reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、飞行器(flight vehicle)、车载设备(Vehicle User Equipment,VUE)、船载设备、行人终端(Pedestrian User Equipment,PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(Personal Computer,PC)、柜员机或者自助机等终端侧设备。可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。其中,车载设备也可以称为车载终端、车载控制器、车载模块、车载部件、车载芯片或车载单元等。需要说明的是,在本申请实施例并不限定终端11的具体类型。

为便于更好的理解本申请实施例,对本申请相关的技术进行说明。
移动通信系统需要适应更加多样化的场景和业务需求,例如5G的主要场景包括增强移动超宽带(Enhance Mobile Broadband,eMBB),高可靠低时延通信(Ultra-Reliable and Low Latency Communication,URLLC),大规模机器类通信(massive machine type of communication,mMTC),这些场景对系统提出了高可靠,低时延,大带宽,广覆盖等要求。针对不同的应用场景,终端需要的传输带宽不同。在NR中,基站可以根据需求,配置和/或调度终端基于不同的带宽进行传输。
在NR中,网络侧为终端配置一个或者多个带宽部分(Band Width Part,BWP)进行数据传输,单个BWP对应频域上一段连续的资源。通过激活不同的BWP可以实现网络侧与终端之间通信带宽的动态适应性变化。如图2所示,第一时刻,终端的业务量较大,此时网络侧为终端激活一个大带宽(BWP1);第二时刻,终端的业务量较小,此时网络侧为终端激活一个小带宽(BWP2),满足基本的通信需求即可;第三时刻,网络侧检测到BWP1所在带宽内有大范围频率选择性衰落,或BWP2所在频率范围内资源较为紧缺,于是在其它频域位置为终端激活一个新的带宽(BWP3)。每个BWP可以对应不同的配置参数,包括子载波间隔、BWP的位置和带宽、循环前缀(Cyclic Prefix,CP)等。
Sub-3GHz频谱(即频率在3GHz以下的无线电波段)具有覆盖范围广、穿透损耗小等优点,因其良好的覆盖性能而在蜂窝网络部署中发挥着重要作用。另一方面,与更高频段相比,Sub-3GHz频谱被碎片化地分配给了不同的无线通信系统,并且由于移动运营商之间的竞争,每个频谱块的带宽相对较窄。另一方面,全球几乎所有运营商都拥有多个Sub-3GHz频段(例如700MHz、800MHz、900MHz、1.4GHz、1.8GHz、2.1GHz、2.3GHz或2.6GHz频段)。
针对Sub-3GHz频谱等频段的离散或碎片频谱,可以将这些离散或碎片频谱聚合形成单个小区。对于某个聚合了离散或碎片频谱的小区,当单个BWP对应的频域资源跨越多个频域部分(Frequency part,FP)时,BWP的频域资源的索引,以及上行(Uplink,UL)/下行(Downlink,DL)信道(channel)/信号(signal)的频域资源分配,目前还没有相应的解决方案。
终端可以有一个或多个服务小区,第一服务小区为终端的其中一个服务小区,该第一服务小区为零散频谱(或者称为碎片频谱)聚合形成的小区。
针对终端的该第一服务小区可以配置一个或者多个BWP,每个BWP对应一个标识(identity,ID),BWP的ID能够唯一区别一个BWP。单个BWP对应的频域资源可以基于该第一服务小区的FP进行配置,也可以不基于该第一服务小区的FP进行配置,例如,可以基于该第一服务小区内的局部频域编号进行配置,或者,基于全局频域编号进行配置。
针对终端的该第一服务小区可以配置M个FP,M大于或等于1,单个FP可以理解为一段连续的频域资源,或者,一个在频域维度上包含连续的频域资源的范围,或者,一个由连续的频域资源构成的集合。
本申请实施例中,不同能力或者类型的终端支持的FP或者FP子集不同,其中,FP子集为第一服务小区能够提供的所有FP的部分FP组成的集合,例如,第一服务小区能够提供的所有FP的数量为P,但是终端只使用了其中M个FP对应的频域资源,M小于或等于P。
假设每个BWP可独立配置CP/SCS等公共参数,以及各信道(channel)/信号(signal)对应的公共(Common)参数和/或专用(Dedicated)参数等。例如,针对某个BWP,对于上行传输,可以配置PRACH的公共参数(例如参数rach-ConfigCommon),PUSCH的公共参数(例如参数pusch-ConfigCommon)和/或专用参数(例如参数pusch-Config和/或configuredGrantConfig),PUCCH的公共参数(例如参数pucch-ConfigCommon)和/或专用参数(例如参数pucch-Config),SRS的专用参数(例如参数srs-Config)等;对于下行接收,可以配置PDCCH的公共参数(例如参数pdcch-ConfigCommon)和/或专用参数(例如参数pdcch-Config),PDSCH的公共参数(例如参数pdsch-ConfigCommon)和/或专用参数(例如参数pdsch-Config和/或sps-Config)等。
对于单个BWP使用的频域资源的范围,或者单个BWP对应的频域资源与第一服务小区的FP对应的频域资源之间的关系,可以采用以下任意一种配置方式:
BWP配置方式1:单个FP对应的部分或所有频域资源被配置为一个BWP,即单个BWP对应的频域资源被限制在单个FP内。
图3为BWP配置方式1的一种示意图,参考图3,左侧图中每个BWP的频域资源分别占用一个FP的所有频域资源,右侧图中BWP1、BWP4、BWP5的频域资源分别占用一个FP的部分频域资源,BWP2、BWP3、BWP6的频域资源分别占用一个FP的所有频域资源。
可以理解,图3只是示意图,当一个BWP占用一个FP的部分频域资源时,该BWP可以占用对应FP的所有频域资源中的上半部分频域资源、下半部分频域资源或者中间部分的频域资源等,本申请实施例不对此进行限制,只要保证BWP占用对应FP的频域资源连续即可。
BWP配置方式2:允许将多个FP对应的部分或所有频域资源配置为一个BWP,即单个BWP对应的频域资源可以位于单个FP内,或者跨越多个FP(对应所在服务小区的部分或所有FP)。
图4为BWP配置方式2的一种示意图,参考图4,左侧图中每个BWP的频域资源分别占用两个FP的所有频域资源,右侧图中BWP1的频域资源占用FP1的所有频域资源和FP2的下半部分频域资源1,BWP2的频域资源占用FP3的所有频域资源和FP4的下半部分频域资源,BWP3的频域资源占用FP5的所有频域资源和FP6的所有频域资源。
可以理解,图4只是示意图。当一个BWP占用两个FP的频域资源时,可以占用其中一个FP的所有频域资源,占用另一个FP的部分频域资源(可以占用该FP的上半部分频域资源、下半部分频域资源或者中间部分的频域资源等);或者,同时占用两个FP的部分频域资源或同时占用两个FP的所有频域资源。在另外一些情况下,某个BWP可以仅占用单个FP的频域资源,或者占用三个FP的频域资源,或者占用更多个FP的频域资源。
当采用BWP配置方式2时,单个BWP对应的频域资源可以跨越多个FP,从而能够并行利用该多个FP的频域资源,以提升网络吞吐性能,同时还可以利用频域选择性或分集增益,并降低管理/控制开销。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的频域资源的操作方法进行详细地说明。下述实施例之间可以相互结合,对于相同或相似的概念、过程可能在某些实施例不再赘述。
实施例一
图5是本申请实施例一提供的频域资源的操作方法的流程图,该方法应用于终端。如图5所示,本实施例提供的方法包括以下步骤。
S101、终端确定第一服务小区的第一BWP对应的频域资源,第一BWP对应的频域资源包括至少一个连续频域资源范围,第一BWP对应的频域资源采用以下任意一种索引方式进行索引:第一BWP对应的所有可用频域资源使用统一分配的VRB编号,第一BWP对应的所有可用频域资源使用统一分配的PRB编号,第一BWP对应的每个连续频域资源范围使用独立分配的PRB编号。
针对终端的第一服务小区可能配置有一个或者多个BWP,第一BWP并不是特指该第一服务小区的某个BWP,而是该第一服务小区的任意一个BWP,即第一服务小区中的每个BWP都可以采用以下任意一种索引方式进行索引(indexing),BWP的频域资源的索引也可以理解为频域资源的编号或者标识。
索引方式1:第一BWP对应的所有可用频域资源使用统一分配的虚拟资源块(Virtual resource block,VRB)编号。
索引方式2:第一BWP对应的所有可用频域资源使用统一分配的(Physical Resource Block,PRB)编号。
索引方式3:第一BWP对应的每个连续频域资源范围使用独立分配的PRB编号。
第一BWP对应的频域资源包括至少一个连续频域资源范围,当第一BWP对应的频域资源包括多个连续频域资源范围时,该多个连续频域资源范围的频域资源互不交叠。
当第一BWP对应的所有可用频域资源使用统一分配的VRB编号时,该所有可用频域资源对应连续的VRB编号。
当第一BWP对应的所有可用频域资源使用统一分配的PRB编号时,且第一BWP对应的频域资源包括多个连续频域资源范围时,该所有可用频域资源对应的PRB编号不连续。
当第一BWP对应的每个连续频域资源范围使用独立分配的PRB编号时,该每个连续频域资源范围内所有可用频域资源对应连续的PRB编号。
本实施例中,终端确定第一服务小区的第一BWP对应的频域资源包括:终端确定第一BWP对应的频域资源的配置信息,根据第一BWP对应的频域资源的配置信息和第一BWP对应的频域资源采用的索引方式,确定第一BWP对应的频域资源,包括确定第一BWP对应的各个频域资源的索引。其中,第一BWP对应的频域资源的配置信息和/或第一BWP对应的频域资源采用的索引方式都可以由网络侧设备指示或者由协议规定。
可选的,本实施例中,从第一BWP的角度看到的可用频域资源(或者,配置给该第一BWP的可用频域资源),可以为如下方案中的任意一种:
方案1、第一BWP对应至少一个绝对资源块(Absolute resource block,ARB)集合(set),每个ARB集合对应一个连续频域资源范围。
方案2、第一BWP对应单个VRB集合(VRB set),该VRB集合中包括至少一个VRB,该VRB集合内的各个VRB与第一BWP对应的可用频域资源之间的映射关系基于预定义映射方式确定。
方案1
每个ARB集合包括至少一个ARB,或者,理解为由一个或多个编号连续的ARB构成的set。
每个ARB为一段预定义宽度的绝对频谱,并且同一个ARB集合内编号/索引相邻的两个ARB对应的绝对频谱也相邻。其中,该预定义宽度与某个SCS对应,例如与该第一BWP在给定传输方向配置的SCS对应,或者,与参考SCS对应,这里的参考SCS可以由协议规定或由高层信令配置。该给定传输方向可以为上行或下行,或者,同时包括上下行(即不区分上下行为该第一BWP统一配置SCS)。
一个ARB集合可以通过如下两种二元组形式表示:(起始ARB编号/索引,ARB数目)或者(起始ARB编号/索引,终止ARB编号/索引)。
任意一个ARB集合的编号/索引参考点可以根据需要设定,ARB集合的编号/索引参考点可以为第一服务小区的公共频率参考点,或者,某个绝对无线频道编号(Absolute Radio Frequency Channel Number,ARFCN)对应的频点,例如0频点,但同一个ARB集合内包含的所有ARB的编号/索引参考点相同。ARB编号/索引方式,包括ARB集合的编号/索引参考点的选择,与BWP频域配置方式有关,具体参见下文中的相应描述。
该公共频率参考点可以根据第一服务小区的小区定义同步信号块(Cell-Defining Synchronization Signal Block,CD-SSB)的频域位置和偏移指示,该偏移指示可以由高层参数offsetToPointA指示,此参数指示相对于第一服务小区的Point A的频域偏移量,Point A为第一服务小区的资源栅格的公共频率参考点。该公共频率参考点还可以根据网络侧配置的绝对无线频道编号(Absolute Radio Frequency Channel Number,ARFCN)确定,例如,由高层参数absoluteFrequencyPointA指示ARFCN,使用此ARFCN对应的绝对频率点作为公共频率参考点。
在方案1中,第一BWP对应的频域资源的配置信息用于确定第一BWP对应的至少一个ARB集合的频域资源范围。
本实施例中,第一BWP对应的至少一个ARB集合可以通过如下三种BWP频域配置方式配置得到,可以理解,不同BWP频域配置方式下,第一BWP对应的频域资源的配置信息不同。
BWP频域配置方式1:为第一BWP配置了至少一个FP,并且对该至少一个FP中的任一FP,其对应的部分或所有频域资源都属于该第一BWP。
该配置方式1中,第一BWP对应的频域资源的配置信息可以为该第一BWP配置的至少一个FP的索引,可选的,还可以包括为该第一BWP配置的至少一个FP的频域资源信息(该频域资源信息可以指示对应FP的所有或者部分连续频域资源)。这里FP的索引,可以理解为FP在第一服务小区的M个FP中的编号或索引或下标,或者,为FP基于协议规定或基于高层信令配置确定的ID。
终端根据为该第一BWP配置的至少一个FP的索引,获取该至少一个FP的频域资源信息,根据该至少一个FP的频域资源信息,确定第一BWP对应的至少一个ARB集合的频域资源范围,其中,每个ARB集合对应一个FP(对于为第一BWP提供频域资源的每个FP,其对应至少一个ARB集合),每个ARB集合的频域资源由对应的FP的所有或部分连续频域资源组成。
可选地,对于为第一BWP提供频域资源的每个FP,其提供的频域资源与单个ARB集合对应。具体地,当第一BWP对应一个FP(即使用一个FP对应的频域资源)时,第一BWP对应一个ARB集合,第一BWP对应的频域资源由该一个ARB集合对应的一个FP的所有或部分连续频域资源组成;当第一BWP对应多个FP(即使用多个FP对应的频域资源)时,第一BWP对应多个ARB集合,第一BWP对应的FP的数量与第一BWP对应的ARB集合的数量相同,即ARB集合与FP一一对应,第一BWP对应的频域资源由该多个ARB集合对应的多个FP的所有或部分连续频域资源组成。
在本实施例中,对于每个FP对应的ARB集合中ARB的编号,编号0对应的ARB可以为该FP上基于对应SCS的第一个可用RB,然后基于频域升序对其它ARB依次编号,但不限制其它实施例中对于ARB的编号方式。
例如,对于图4中的配置方式2中的左侧配置方式,BWP1占用FP1和FP2各自对应的所有频域资源,其中FP1对应ARB集合0,FP2对应ARB集合1;BWP2占用FP3和FP4各自对应的所有频域资源,其中FP3对应ARB集合0,FP4对应ARB集合1;BWP3占用FP5和FP6各自对应的所有频域资源,其中FP5对应ARB集合0,FP6对应ARB集合1。
可选地,BWP也可以只占用某个FP的部分频域,例如,对于图4中的配置方式2中的右侧配置方式,BWP1可以占用FP1的所有频域资源(可对应ARB集合0),以及FP2的下半部分的频域资源(可对应ARB集合1)。BWP2可以占用FP3的所有频域资源(可对应ARB集合0),以及FP4的下半部分的频域资源(可对应ARB集合1)。
BWP频域配置方式2:为第一BWP配置至少一个ARB集合,每个ARB集合对应一个连续频域资源范围。
该配置方式中,第一BWP对应的频域资源的配置信息包括第一BWP对应的各ARB集合的频域资源信息。
当为第一BWP配置了多个ARB集合时,该多个ARB集合对应的连续频域资源范围相互之间不存在交叠。该多个ARB集合中各个ARB集合的ARB编号的起始点可以共用第一服务小区的公共频率参考点,或者,使用各自对应的参考点。
第一服务小区的公共频率参考点的描述参照前述相关描述,ARB集合各自对应的参考点可以基于网络侧配置的ARFCN确定,或者,基于网络侧配置的频段(band)号对应的Band的起始频点或结束频点确定,band可以为RAN4协议中的NR operating band或频段。
可选的,该配置方式2中,由网络侧配置保证各ARB集合中任一ARB对应的频域资源都落入/位于第一服务小区的某个FP内。
BWP频域配置方式3:为第一BWP配置一个第四ARB集合以及至少一个第五ARB集合,该第四ARB集合用于确定该第一BWP对应的频域跨度范围,每个第五ARB集合对应该频域跨度范围内的一段连续的不可用频域资源,各第五ARB集合的频域资源相互之间不存在交叠。
该配置方式中,第一BWP对应的频域资源的配置信息包括第四ARB集合的频域资源信息和至少一个第五ARB集合的频域资源信息。
该第一BWP对应的频域跨度范围内同时包含可用频域资源和不可用频域资源,每个第五ARB集合对应的频域资源都为不可用频域资源,终端根据该频域跨度范围内的所有频域资源和每个第五ARB集合对应的不可用频域资源,从该频域跨度范围内的所有频域资源中排除掉该至少一个第五ARB集合对应的不可用频域资源,将该频域跨度范围内的剩余频域资源(都作为可用频域资源)作为该第一BWP对应的频域资源。
其中,各第五ARB集合中ARB编号的起始点可以共用所在服务小区的公共频率参考点,或者,使用各自对应的参考点,本实施例不对此进行限制。
当第一BWP对应至少一个ARB集合时,终端根据第一BWP对应的至少一个ARB集合和第一BWP的频域资源的索引方式,确定第一BWP对应的频域资源的索引。第一BWP的频域资源的索引方式可以由协议规定或者由网络侧设备指示,第一BWP的频域资源的索引方式为以下方式中的任意一种:第一BWP对应的所有可用频域资源使用统一分配的VRB编号;第一BWP对应的所有可用频域资源使用统一分配的PRB编号;第一BWP对应的每个连续频域资源范围使用独立分配的PRB编号。第一BWP对应的频域资源的索引的具体确定方式参见下述实施例二至实施例四的描述。
方案2
第一BWP对应单个VRB集合,第一BWP对应的频域资源的配置信息为该VRB集合的频域资源信息,该VRB集合的频域资源信息可以为该VRB集合包含的各VRB的编号,或者该VRB集合包含的VRB的编号范围。
该VRB集合内的各个VRB与第一服务小区的可用频域资源之间的映射关系基于预定义映射方式确定。
当第一服务小区的可用频域资源包括多个FP的频域资源时,一种可能的预定义映射方式为:将第一服务小区对应的多个FP对应的物理频域资源转换成RB粒度(此RB粒度与某个SCS对应,例如与该第一BWP在给定传输方向配置的SCS对应,或者,与参考SCS对应,这里的参考SCS可以由协议规定或由高层信令配置),然后将各个FP对应的RB基于FP之间的预定义顺序作统一排序,得到单个RB队列,并针对该RB队列中的各个RB依次分配连续的VRB编号,例如该RB队列中的第一个RB对应VRB C,该RB队列中的最后一个RB对应VRB D(D=C+队列中包含的RB数目-1)。同一个FP对应的物理频域资源转换成的RB分配连续的VRB编号。
这里将该第一服务小区对应的多个FP对应的RB基于FP之间的预定义顺序作统一排序可以理解为,为该多个FP对应的RB进行排序,以形成一个RB队列。在此RB队列中,同一个FP对应的RB相邻或连续,或者,位于单个区间内。
可选的,该FP之间的预定义顺序,可以采用以下任一项:
(1)根据配置的FP列表中多个FP的索引的升序或降序,对这多个FP进行排序。
(2)根据该第一服务小区对应的多个FP的起始/截止频率的升序或降序,对这多个FP进行排序。
第一BWP对应的单个VRB集合可以理解为由一到多个编号连续的VRB构成的集合,该ARB集合可以通过如下两种二元组形式表示:(起始VRB编号/索引,VRB数目)或者(起始VRB编号/索引,终止VRB编号/索引)。例如,该VRB集合对应上述VRB C~D中的某一段编号对应的VRB。
当第一BWP对应单个VRB集合时,终端根据第一BWP对应的该VRB集合和第一BWP的频域资源的索引方式,确定第一BWP对应的频域资源的索引。该第一BWP的频域资源的索引方式为第一BWP对应的所有可用频域资源使用统一分配的VRB编号,由于该第一BWP对应的该VRB集合中各VRB已经具有连续编号,因此,可以直接使用该第一BWP对应的该VRB集合中各VRB编号,或者,对该第一BWP对应的该VRB集合中各VRB编号都统一偏移一定的数量(即,将各VRB编号都偏移此相同的数量),例如使得作完偏移之后该第一BWP对应的该VRB集合中的第一个VRB的编号被调整为0,得到该第一BWP对应的频域资源的索引。
可选的,本申请实施例中终端的第一服务小区同一时刻可以同时处于激活(Active)态的BWP最大数量,可以采用如下两种激活模式中的任意一种模式确定:
BWP激活模式1:Single active BWP,即同一时刻只允许单个处于Active的BWP。
BWP激活模式2:Multiple active BWPs,即同一时刻可允许多个处于Active的BWP,但也有可能在某些时刻终端只工作在单个Active BWP。
需要明确是,该第一服务小区的至少一个BWP的频域资源可以由协议规定或由高层信令配置。当由高层信令配置时,可以由系统信息广播(所有支持接入到该第一服务小区,或者所有将该第一服务小区作为服务小区的终端看到的信息一致,可用于小区选择/重选、初始接入等场景),或者,由无线资源控制(Radio Resource Control,RRC)专用信令配置(所有支持接入到该第一服务小区,或者所有将该第一服务小区作为服务小区的终端看到的信息可能一致或不同,可用于SCell配置/修改等场景)。具体的高层信令形式,可以采用位图(Bitmap)的方式指示协议规定或高层信令预配置多个连续频域资源范围,或者,采用列表的方式配置一到多个元素,每个元素与每个连续频域资源范围一一对应。
S102、终端根据第一BWP对应的频域资源,确定为第一传输分配的频域资源。
终端可以根据第一BWP对应的频域资源的范围、索引以及网络侧设备发送的第一传输的资源调度信息或资源分配信息,确定为第一传输分配的频域资源。
该第一传输包括以下信号或者信道中的一个或者多个:上行信道、上行信号、下行信道或者下行信号。
终端根据为第一传输分配的频域资源,执行第一传输的收发,包括发送和/或接收。
本实施例中,终端确定第一服务小区的第一BWP对应的频域资源,第一BWP对应的频域资源包括至少一个连续频域资源范围,第一BWP对应的频域资源采用以下任意一种索引方式进行索引:第一BWP对应的所有可用频域资源使用统一分配的VRB编号,第一BWP对应的所有可用频域资源使用统一分配的PRB编号,第一BWP对应的每个连续频域资源范围使用独立分配的PRB编号;终端根据第一BWP对应的频域资源,确定为第一传输分配的频域资源。BWP对应的频域资源可以由一个或者多个零散频谱组成,通过为零散频谱聚合形成的第一服务小区的BWP提供不同的频域资源的索引方式,从而能够有效利用零散频谱资源进行数据传输,提升数据传输的速率、时延等性能。
实施例二
本实施例主要对BWP频域资源的索引方式1,以及基于该索引方式1的UL/DL channel/signal的频域资源分配方法进行说明。
该索引方式1可以应用于上述方案1中,第一BWP对应至少一个ARB集合,终端根据第一BWP对应的至少一个ARB集合和BWP的频域资源的索引方式1,将第一BWP对应的至少一个ARB集合的ARB映射为连续的VRB,或者为第一BWP对应的至少一个ARB集合的ARB分配连续的VRB编号,得到第一BWP对应的频域资源的索引。该索引方式1中,第一BWP对应的所有可用频域资源使用统一分配的VRB编号,当第一BWP对应的所有可用频域资源使用统一分配的VRB编号时,第一BWP对应的多个ARB集合的ARB基于ARB集合粒度映射为连续的VRB,或,第一BWP对应的多个ARB集合的ARB基于ARB粒度映射为连续的VRB。
当第一BWP对应多个ARB集合时,终端可以采用如下任意一种VRB映射方式将第一BWP对应的多个ARB集合的ARB映射为连续的VRB:VRB映射方式1和VRB映射方式2,以下分别对两种VRB映射方式进行详细说明。
这里将第一BWP对应的多个ARB集合的ARB映射为连续的VRB可以理解为至少包括对第一BWP对应的多个ARB集合的ARB分配连续的VRB编号。
VRB映射方式1:基于ARB集合粒度将第一BWP对应的多个ARB集合的ARB映射为连续的VRB。
当基于ARB集合粒度将第一BWP对应的多个ARB集合的ARB映射为连续的VRB时,在同一个ARB集合内相邻的ARB对应连续的VRB编号。
不同ARB集合之间分配VRB编号的先后顺序,或者,不同ARB集合对应的VRB编号范围的先后顺序,基于以ARB集合为粒度的预定义方式确定。
示例性的,根据第一排序或第二排序为第一BWP对应的多个ARB集合中的各个ARB集合依次分配连续的VRB编号。其中,第一排序为根据第一BWP对应的多个ARB集合中各个ARB集合的预定义ARB的频率,按照升序或降序进行排序得到的第一BWP对应的多个ARB集合之间的排列顺序。第二排序为根据交织(Interleaving)模式对第一排序进行调整得到的第一BWP对应的多个ARB集合之间的排列顺序。
在确定第一排序时,第一BWP对应的多个ARB集合中各个ARB集合的预定义ARB可以为各个ARB集合内的第一个位置、最后一个位置或者指定位置的ARB,终端根据各个ARB集合内的第一个位置、最后一个位置或者指定位置的ARB的频率对该多个ARB集合做升序排列或者降序排列,得到第一排序。
例如,第一BWP对应8个ARB集合,根据各个ARB集合中的第一个ARB的频率对8个ARB集合进行升序排列或者降序排列,得到第一排序。
一种实现方式中,根据交织模式对第一排序进行调整时,可以采用如下公式f(x)确定各ARB集合的最终遍历顺序(即第二排序)为:f(0),f(1)…f(N-1),其中,N为第一排序中ARB集合的数量,或者,交织模式对应的交织器可支持的ARB集合的最大数量。
f(x)=(rC+c+nshift)mod N
x=cR+r
r=01,…,R-1
c=0,1,…,C-1
上述公式f(x)中各变量的含义如下:
R:交织器的行数,取值为正整数
C:交织器的列数,取值为正整数
nshift:交织器的偏移,取值为非负整数
N=R*C:交织器内元素数目
上述R、C和nshift等参数均可由协议规定或由高层信令配置。
一般地,在确定第二排序时,第一BWP对应的ARB集合的数量M等于交织器可支持的ARB集合的最大数量N;可选的,允许M<N,此时,在遍历ARB集合n(n>(M-1);假设n从0开始编号)时将忽略/跳过对应的操作,即对ARB集合n(n>(M-1))内的ARB不分配VRB编号(此时也可以理解为ARB集合n(n>(M-1))是为了使用交织器而填充的占位ARB集合,其并不属于第一BWP对应的ARB集合)。
交织器的一个示例如下述表一所示:
表一
假设该BWP对应8个ARB集合,该8个ARB集合的第一排序为0->1->2->3->4->5->6->7,该第一排序通过表1所示交织器进行交织处理后,该8个ARB集合的第二排序为:0->4->1->5->2->6->3->7。
假设该BWP对应6个ARB集合,该6个ARB集合的第一排序为0->1->2->3->4->5,该第一排序通过表1所示交织器进行交织处理后,该6个ARB集合的第二排序为:0->4->1->5->2->3,其中,索引6和7对应的操作被忽略或者跳过,也就是说忽略索引6和7对应的ARB集合,即不对索引6和7对应的ARB集合分配VRB编号。
在确定第一BWP对应的多个ARB集合的第一排序或者第二排序后,根据该第一排序或者第二排序逐一为各个ARB集合中的各个ARB分配连续的VRB编号。
可选地,根据第一排序或者第二排序,将第一个遍历的ARB集合的第一个ARB分配预定义的VRB编号start(例如分配VRB编号0,即该ARB对应VRB 0),假设某个ARB集合的最后一个ARB对应VRB k,则下一个遍历的ARB集合的第一个ARB对应VRB(k+1)。最后遍历的ARB集合的最后一个ARB可对应VRB(start+sum-1),sum为第一BWP对应的多个ARB集合内包含的ARB总数。
例如,假设第一BWP对应2个ARB集合,ARB集合0对应30个VRB,ARB集合1对应50个VRB。假设基于各ARB集合内第一个ARB的频率作升序排列,得到第一排序(也称为遍历顺序)为ARB集合0->ARB集合1,且start=0,则ARB集合0对应的VRB编号范围为0~29(即ARB集合0内各ARB依次对应VRB 0~29),ARB集合1对应的VRB编号范围为30~79。
VRB映射方式2:基于ARB粒度将第一BWP对应的多个ARB集合的ARB映射为连续的VRB。
当基于ARB粒度将第一BWP对应的多个ARB集合的ARB映射为连续的VRB时,在同一个ARB集合内相邻的ARB对应的VRB编号可能不连续。
示例性的,根据第三排序或第四排序为第一BWP对应的多个ARB集合中的各个ARB依次分配连续的VRB编号。其中,第三排序为根据第一BWP对应的多个ARB集合中的各个ARB对应的频率,按照升序或者降序进行排序得到的第一BWP对应的多个ARB集合中的各个ARB之间的排列顺序。第四排序为根据交织模式对第三排序进行调整得到的第一BWP对应的多个ARB集合中的各个ARB之间的排列顺序。
该映射方式中,在确定第三排序时,将第一BWP对应的多个ARB集合中的各个ARB统一按照频率从低到高或从高到低依次分配连续的VRB编号,不需要考虑多个ARB集合之间的先后顺序,相应的,分配得到的同一个ARB集合内相邻的ARB对应的VRB编号可能不连续。
在一些情况下,根据第一排序和第三排序为第一BWP对应的多个ARB集合中的各个ARB分配的VRB编号完全一致。
一般地,在确定第四排序时,第一BWP对应的ARB总数M等于交织器可支持的ARB最大数量N;可选的,允许M<N,此时,在遍历ARB n(n>(M-1);假设n从0开始编号)时将忽略/跳过对应的操作,即对ARB n(n>(M-1))不分配VRB编号(此时也可以理解为ARB n(n>(M-1))是为了使用交织器而填充的占位ARB,其并不属于第一BWP对应的ARB)。
当第一BWP对应一个ARB集合时,可以采用上述VRB映射方式2将该ARB集合内的ARB映射为连续的VRB,即根据ARB粒度将该ARB集合对应的ARB映射为连续的VRB。示例性的,根据第五排序或者第六排序为该ARB集合中的各个ARB依次分配连续的VRB编号。其中,该第五排序为根据该ARB集合中的各个ARB对应的频率,按照升序或者降序进行排序得到的该ARB集合中的各个ARB之间的排列顺序,第六排序为根据交织模式对第五排序进行调整得到的该ARB集合中的各个ARB之间的排列顺序。具体实现方式参照上述VRB映射方式2的描述,这里不再赘述。
对于方案1或方案2,该第一BWP(假设编号为i)在给定传输方向的VRB编号范围可以为0~(-1),其中与给定传输方向的SCS对应,为BWP i内的VRB总数。对于UL/DL channel/signal的频域资源分配,可以沿用NR中的相应机制,仅在映射具体的RB时,将NR中的PRB替换为这里的VRB。
本实施例中,当采用VRB映射方式2时,在BWP的频域资源的索引过程中引入交织操作。可选的,对于支持配置交织(Interleaving)操作的信道,可以采用以下任意一项配置限制:不允许为该信道再进一步配置开启交织操作;允许为该信道进一步配置开启交织操作。当为该信道进一步配置开启交织操作时,在上述VRB映射的基础上,可以沿用NR中的相应机制。
支持配置交织操作的信道至少包括支持VRB-to-PRB交织映射的下行共享物理信道(Physical Downlink Share Channel,PDSCH),以及支持CCE-to-REG交织映射的物理下行控制信道(Physical Downlink Control Channel,PDCCH)。
实施例三
本实施例主要对BWP频域资源的索引方式2,以及基于该索引方式2的UL/DL channel/signal的频域资源分配方法进行说明。
该索引方式2可以应用于上述方案1中,第一BWP对应至少一个ARB集合,终端根据第一BWP对应至少一个ARB集合和BWP的频域资源的索引方式2,为第一BWP对应的至少一个ARB集合的ARB分配PRB编号,得到第一BWP对应的频域资源的索引。
第一BWP对应一个或者单个ARB集合。当第一BWP对应多个ARB集合时,终端可以采用如下映射方式为第一BWP对应的多个ARB集合分配PRB编号:确定第一BWP对应的多个ARB集合中的频率最低的ARB和频率最高的ARB,为频率最低的ARB分配起始PRB编号,按照频率从低到高的顺序,依次为位于该频率最低的ARB和该频率最高的ARB之间的所有ARB,以及该频率最高的ARB分配连续的PRB编号。
例如,将该第一BWP对应的多个ARB集合中,频率最低的ARB作为PRB 0(即起始PRB编号),并从下一个ARB(例如与PRB 0相邻且频率更高的ARB)开始继续逐一顺序编号,直至为该BWP对应的多个ARB集合中频率最高的ARB分配编号为止,假设该第一BWP对应的多个ARB集合中频率最高的ARB分配的编号为PRB(L–1),则为该第一BWP总共配置了L个名义PRB,名义PRB的索引范围为0~(L-1)。
需要明确的是,上述映射方式中,在从频率最低的ARB到频率最高的ARB为各个ARB依次分配连续的PRB编号时,不关注遍历的各个ARB是否可用,即不判断遍历的各个ARB是否属于该第一BWP对应的某个ARB集合。相应地,为第一BWP配置的L个名义PRB中有些名义PRB是可用的,有些名义PRB是不可用的。
通过上述映射方式得到的第一BWP对应的PRB包括:多个有效PRB集合(即Valid PRB set)和至少一个无效PRB集合(Invalid PRB set)。其中,该有效PRB集合内的任意一个PRB对应的频域资源属于第一BWP对应的某个ARB集合,该无效PRB集合内的任意一个PRB对应的频域资源不属于该第一BWP对应的任意一个ARB集合。
该多个有效PRB集合组成了该第一BWP的所有可用频域资源,因此,当第一BWP对应的频域资源包括多个连续频域资源范围时,或者理解为第一BWP对应多个ARB集合时,该第一BWP的所有可用频域资源对应的PRB编号不连续。
以为该第一BWP配置了L个名义PRB为例,相应的,终端依次遍历该L个名义PRB,判断当前名义PRB是否属于该第一BWP对应的某个ARB集合内,如果当前名义PRB属于该第一BWP对应的某个ARB集合,则确定当前名义PRB为可用PRB,如果当前名义PRB不属于该第一BWP对应的任意一个ARB集合,则确定当前名义PRB为不可用PRB。
该L个名义PRB中的所有可用PRB进一步构成多个有效PRB集合,该L个名义PRB中的所有不可用PRB进一步构成至少一个无效PRB集合。
每个有效PRB集合包括至少一个有效PRB,每个无效PRB包括至少一个无效PRB,以第一BWP对应的多个ARB集合中每个ARB集合对应一个FP的所有或者部分频域资源为例,假设第一BWP对应3个ARB集合:ARB集合0、ARB集合1和ARB集合2,其中,ARB集合0对应FP0的所有频域资源,ARB集合1对应FP1的所有频域资源,ARB集合3对应FP2的所有频域资源,假设FP0、FP1和FP2对应的起始频率或结束频率依次增大,则位于FP0、FP1和FP2的频域资源内的名义PRB为有效PRB,位于FP0、FP1和FP2的频域资源之间的名义PRB为无效PRB。
可以将位于FP0的频域资源内的所有名义PRB构成一个有效PRB集合,将位于FP1的频域资源内的所有名义PRB构成一个有效PRB集合,将位于FP2的频域资源内的所有名义PRB构成一个有效PRB集合,总共形成三个有效PRB集合。将位于FP0的频域资源和FP1的频域资源之间的所有名义PRB构成一个无效PRB集合,将位于FP1的频域资源和FP2的频域资源之间的所有名义PRB构成一个无效PRB集合,总共形成两个无效PRB集合。
当第一BWP对应一个ARB集合时,根据该ARB集合中的ARB的频率将该ARB集合中的ARB映射为连续的PRB。例如,针对该ARB集合,将该ARB集合内频率最低的ARB作为PRB 0,并从下一个ARB(例如与PRB 0相邻且频率更高的ARB)开始继续逐一顺序编号,直至为该ARB集合中频率最高的ARB分配PRB编号为止。
第一BWP对应的该一个ARB集合对应的PRB组成了该第一BWP的所有可用频域资源,因此,当第一BWP对应的频域资源包括一个连续频域资源范围时,或者理解为第一BWP对应一个ARB集合时,该第一BWP的所有可用频域资源对应的PRB编号连续。
基于索引方式2为UL/DL channel/signal分配频域资源时,可选的,可以采用以下任意一种频域资源分配机制为第一传输分配频域资源。
资源分配机制1:
当第一传输包括第一类传输时,为该第一类传输分配的连续频域资源位于第一BWP对应的单个有效PRB集合内,其中,该第一类传输为要求分配的频域资源连续的传输,该第一类传输包括以下传输中的至少一种:
信道状态信息参考信号(Channel Status Information Reference Signal,CSI-RS);
使用资源分配类型1的物理上行共享信道(Physical Uplink Share Channel,PUSCH);
使用资源分配类型1的物理下行共享信道(Physical Downlink Share Channel,PDSCH);
物理上行控制信道(Physical Uplink Control Channel,PUCCH);
探测参考信号(Sounding Reference Signal,SRS);
物理随机接入信道(Physical Random Access Channel,PRACH)。
该资源分配机制1中,基于已有机制,只有当为该第一类传输分配的连续频域资源限制在单个有效PRB集合内时,该第一传输才能进行正常的收发;当为该第一类传输分配的连续频域资源位于第一BWP对应的多个有效PRB集合内时,即为第一类传输分配的连续频域资源跨越了多个有效PRB集合时,该第一类传输不能进行正常的收发。
可选的,该单个有效PRB集合可以位于第一BWP对应的某个连续频域资源范围内或者某个FP的频域资源范围内,即为第一BWP对应的有效PRB集合中的一个有效PRB集合。
频域资源分配机制2:
当第一传输包括下行信道和/或下行信号时,为下行信道和/或下行信号分配的频域资源允许同时使用第一BWP包括的多个有效PRB集合对应的频域资源。每个有效PRB集合可以视为子带全双工(Subband Full Duplex,SBFD)的下行子带(DL subband)。本实施例中,不对下行信道和/或下行信号允许同时使用的有效PRB集合的数量进行限制,下行信号允许同时使用的有效PRB集合的数量可以为2个或者大于2个。
当第一传输包括PDSCH、PDCCH、CSI-RS或CSI上报时,PDSCH、PDCCH、CSI-RS或CSI上报可采用SBFD中的类似机制,并引入相应的增强,可选的,包括以下至少一项增强:
(1)针对第一传输的频域资源跨越多个有效PRB集合且为该第一传输分配非连续频域资源的相关增强
第一传输的频域资源跨越多个有效PRB集合,可以理解为为该第一传输分配的频域资源位于多个有效PRB集合中。
对于采用资源分配类型0(Resource allocation type 0)的PDSCH,可以沿用NR中基于Bitmap指示频域资源分配信息的机制,无需进一步引入增强。
对于采用Resource allocation type 1的PDSCH,可以在采用NR中基于资源指示值(Resource Indication Value,RIV)指示频域资源分配信息的机制的基础上,将分配的连续频域资源再针对其可能包含的无效PRB作打孔(Puncturing)处理或者速率匹配(Rate matching)处理,避免使用这些无效PRB(对应涉及的无效PRB集合中的部分PRB或所有PRB),从而能够提高数据传输的可靠性。
对于采用宽频段(Wideband)物理资源组(Physical Resource Group,PRG)的PDSCH,允许为采用该Wideband PRG的PDSCH分配的频域资源位于第一BWP对应的多个有效PRB集合中,即允许为该PDSCH分配的频域资源跨越多个有效PRB集合,但在每个有效PRB集合内分配的频域资源连续。
可选地,为采用该Wideband PRG的PDSCH在单个有效PRB集合内分配的所有PRB应用Wideband PRG(即应用统一的宽带预编码矩阵),但是在不同的有效PRB集合内分配的PRB应用的Wideband PRG允许不同,即可以为此PDSCH在各个有效PRB集合内分配的PRB分别或独立确定/指示应用的Wideband PRG或宽带预编码矩阵,即不同的有效PRB集合内分配的频域资源应用的Wideband PRG可能不同,从而能够为不同的频域资源采用匹配的预编码矩阵进行传输,提高数据传输的可靠性和传输效率。
对于CSI-RS接收,如果该CSI-RS接收对应的频域资源位于第一BWP对应的多个有效PRB集合中,可以采用以下任意一种方式配置该CSI-RS接收对应的频域资源:
方式一、将该CSI-RS接收在各个有效PRB集合内的频域资源分配视为针对单个独立CSI-RS资源的频域资源分配,并且将该多个有效PRB集合各自对应的CSI-RS资源关联起来使用,例如这些CSI-RS资源各自对应独立的CSI-RS资源ID,但这些CSI-RS资源总是作为一个子集统一使用(或者作为一个整体统一使用)。
方式二、将该CSI-RS接收在各个有效PRB集合内的频域资源分配视为针对同一个CSI-RS资源的频域资源分配的不同部分,即这些不同部分对应同一个CSI-RS资源ID并统一使用,也可以理解为为该CSI-RS接收在多个有效PRB集合内分配的所有频域资源使用同一个CSI-RS资源ID。当这些不同部分对应同一个CSI-RS资源ID或者为该CSI-RS接收在多个有效PRB集合内分配的所有频域资源使用同一个CSI-RS资源ID时,为该CSI-RS接收在多个有效PRB集合内分配的所有频域资源默认同时使用。
可选的,该CSI-RS资源(与单个CSI-RS资源ID对应)可以采用以下任一方式配置:
方式一、该CSI-RS资源在每个有效PRB集合内的频域资源分配可独立配置。
方式二、沿用NR机制配置该CSI-RS资源对应的连续频域资源,该连续频域资源可以跨越多个有效PRB集合,以及该多个有效PRB集合之间的无效PRB集合。例如在配置该连续频域资源时,可以使用参数startingRB和nrofRBs分别配置该连续频域资源在该第一BWP的名义PRB索引范围内的起始PRB索引和连续PRB数目。为该CSI-RS资源实际分配的频域资源为该连续频域资源落入跨越的各个有效PRB集合内的频域资源,或者为该连续频域资源在排除落入跨越的各个无效PRB集合内的频域资源之后,剩余的频域资源,即为该CSI-RS资源实际分配的是非连续频域资源。
(2)针对频域资源粒度与有效PRB集合边界不对齐的相关增强
对于采用Resource allocation type 0的PDSCH,当某个RBG仅部分PRB位于有效PRB集合内时,此RBG位于Valid PRB集合之外的部分不能用于PDSCH接收。
对于PRG大小为2或4的PDSCH,当某个PRG仅部分PRB位于有效PRB集合内时,此PRG位于Valid PRB集合之外的部分不能用于PDSCH接收,或者,此PRG位于有效PRB集合内的部分可用于PDSCH接收。
对于CSI上报,当某个CSI上报子带(CSI reporting subband)仅部分PRB位于Valid PRB集合内时,仅基于该CSI上报子带位于Valid PRB集合内的PRB部分内的CSI-RS资源推导该CSI上报子带对应的CSI report,或者,在推导该CSI上报子带对应的CSI report时使用的CSI-RS资源排除该CSI上报子带位于Valid PRB集合之外的部分。
当第一传输包括第二类传输时,该第二类传输包括以下传输中的至少一种:采用资源分配类型1(即Resource allocation type 1)的PUSCH、PUCCH或者SRS,为该第二类传输分配的频域资源可能包括位于无效PRB集合内的频域资源,相应的,终端采用以下任意一项确定为第二类传输分配的频域资源:
接收第一信息,该第一信息指示为第二类传输分配的连续频域资源,当为第二类传输分配的连续频域资源包括第一无效PRB集合对应的频域资源(即位于第一无效PRB集合内的频域资源,可以为第一无效PRB集合的部分或所有频域资源)时,终端采用打孔(Puncturing)方式或者速率匹配方式(Rate matching),避免使用第一无效PRB集合对应的频域资源。
接收第二信息,该第二信息指示至少一个资源块RB簇(cluster),每个RB簇对应连续频域资源,该连续频域资源位于第一有效PRB集合内。
其中,该第一无效PRB集合为第一BWP包括的至少一个无效PRB集合中的任意一个无效PRB集合,该第一有效PRB集合为第一BWP包括的多个有效PRB集合中的任意一个有效PRB集合。
当终端接收到第一信息时,终端根据该第一信息和该第一BWP的频域资源,确定为该第二传输分配的频域资源。当终端接收到第二信息时,终端根据该第二信息和该第一BWP的频域资源,确定为该第二传输分配的频域资源。
对于第二类传输,可以采用已有的频域资源分配信息配置/指示机制指示为该第二类传输分配的连续频域资源。例如,对于Resource allocation type 1的PUSCH,可以通过资源指示值(Resource Indication Value,RIV)指示为此PUSCH分配的连续频域资源。对于PUCCH和SRS可以显式配置或基于相关机制确定每次传输对应的起始PRB索引和PRB数目。
对于第二类传输,可以采用已有的频域资源分配信息配置/指示机制指示为该第二类传输分配的至少一个RB簇。
对于采用Resource allocation type 0的PUSCH,可以基于Bitmap指示频域资源分配信息。当某个RBG仅部分PRB位于有效PRB集合内时,此RBG位于有效PRB集合之外的部分不能用于PUSCH传输。
实施例四
本实施例主要对BWP频域资源的索引方式3,以及基于该索引方式3的UL/DL channel/signal的频域资源分配分配方法进行说明。
该索引方式3可以应用于上述方案1中,第一BWP对应至少一个ARB集合,终端根据第一BWP对应至少一个ARB集合和BWP的频域资源的索引方式3,为第一BWP对应的各个ARB集合分别分配PRB编号,即第一BWP对应的各个ARB集合独立分配PRB编号,得到第一BWP对应的频域资源的索引。
当第一BWP对应多个ARB集合时,可以采用如下映射方式为第一BWP对应的每个连续频域资源范围分配PRB编号:根据第一ARB集合中的ARB的频率将第一ARB集合中的ARB映射为连续的PRB,第一ARB集合为第一BWP对应的多个ARB集合中的任意一个ARB集合。
例如,针对第一ARB集合,将该第一ARB集合内频率最低的ARB作为PRB 0,并从下一个ARB(例如与PRB 0相邻且频率更高的ARB)开始继续逐一顺序编号,直至为该第一ARB集合中频率最高的ARB分配编号为止,假设该第一ARB集合中频率最高的ARB分配的编号为PRB(M–1),M为该第一ARB集合内包含的ARB或者PRB数目。
该映射方式中,每个ARB集合内的ARB是连续的,为每个ARB集合独立分配RRB编号,从而使得每个连续频域资源范围内所有可用频域资源对应连续的PRB编号。
基于索引方式3为UL/DL channel/signal分配频域资源时,可以采用以下任意一种频域资源分配方式为第一传输分配频域资源。
频域资源分配方式1、网络侧设备指示至少一套频域资源分配信息,该至少一套频域资源分配信息中的每套频域资源分配信息与第二ARB集合中的单个ARB集合对应,其中,第二ARB集合为为第一传输分配频域资源的至少一个ARB集合。
终端接收该至少一套频域资源分配信息,根据该至少一套资源分配信息和第一BWP对应的频域资源,确定为第一传输分配的频域资源。
可选的,可以采用列表方式配置/指示至少一个元素,每个元素与一套频域资源分配信息一一对应。例如,每个元素包含一套频域资源分配信息,以及应用此套频域资源分配信息的ARB集合的索引。这里的ARB集合的索引,可以理解为ARB集合在第一BWP对应的所有ARB集合(或者,第一BWP对应的所有ARB集合中的至少一个ARB集合构成的子集)中的编号或索引或下标,或者,为ARB集合基于协议规定或基于高层信令配置确定的ID。
频域资源分配方式2、网络侧设备指示一套通用资源分配信息,该通用资源分配信息应用于第二ARB集合中的各个ARB集合,其中,第二ARB集合为为第一传输分配频域资源的至少一个ARB集合。
终端接收该通用资源分配信息,根据该通用资源分配信息和第一BWP对应的频域资源,确定为第一传输分配的频域资源。
一般地,在针对第二ARB集合中的各个ARB集合分别应用该通用资源分配信息时,可以直接在此ARB集合对应的PRB编号范围内应用该通用资源分配信息。可选地,为该第二ARB集合中的每个ARB集合分别确定一个应用该通用资源分配信息的参考点,例如PRB A,可以由协议规定或由高层信令配置,例如规定PRB A为PRB 0。该通用频域资源分配信息在对应到第二ARB集合中的每个ARB集合内实际分配的PRB时,需要在基于该通用频域资源分配信息确定分配的PRB之后,整体再偏移A个PRB,得到在此ARB集合内实际分配的PRB位置。
可选地,可以确定一个参考ARB集合,网络侧设备基于该参考ARB集合确定和指示该通用资源分配信息,并且终端基于该参考ARB集合接收和解读该通用资源分配信息(之后再应用该通用资源分配信息,参见前述描述)。该参考ARB集合基于以下至少一项确定:
由网络侧设备配置或指示;
为第一BWP对应的多个ARB集合中或第二ARB集合中满足以下至少一项的ARB集合:
ARB或者PRB数目最少或者最多的ARB集合;
预定义ARB或PRB的频率最低或者最高的ARB集合;
位于同步信号块SSB所在的频域部分的ARB集合;
用于监听公共搜索空间(Common Search Space,CSS)的ARB集合;
索引最小或最大的ARB集合;
位于索引最小或最大的FP的ARB集合。
当由网络侧设备配置或指示该参考ARB集合时,网络侧设备可以显示的配置或指示该参考ARB集合的索引。
在指示第二ARB集合时,可以采用Bitmap的方式配置/指示第一BWP对应的多个ARB集合中的一到多个ARB集合,或者,采用列表的方式配置/指示一到多个ARB集合的索引。
在实际资源分配过程中,存在该通用资源分配信息与第三ARB集合不兼容的情况,该第三ARB集合与该通用资源分配信息不兼容包括:基于该通用资源分配信息确定的需要占用的至少一个PRB编号超出了第三ARB集合对应的PRB编号范围。其中,第三ARB集合为第二ARB集合中的任意一个ARB集合,第二ARB集合为为第一传输分配频域资源的至少一个ARB集合。
可选的,当该通用资源分配信息与第三ARB集合不兼容时,终端执行以下任意一项操作:
仅使用PRB编号位于第三ARB集合对应的PRB编号范围内的PRB;
使用第三ARB集合内与第一PRB编号对应的PRB,其中,第一PRB编号为将第二PRB编号对第一数量作取模运算得到,第二PRB编号为基于该通用资源分配信息确定的需要占用的任意一个PRB对应的编号,该第一数量为第三ARB集合实际包含的PRB数量;
不使用第三ARB集合对应的频域资源;
不执行第一传输对应的发送或者接收;
终端不期望出现这种情况。
例如,假设第三ARB集合对应的PRB编号范围为0-29,根据该通用资源分配信息确定的需要占用的第二PRB编号范围为20-31,则PRB编号30和PRB编号31超出了第三ARB集合对应的PRB编号范围,此时该通用资源分配信息与第三ARB集合不兼容。当终端使用第三ARB集合内与第一PRB编号对应的PRB时,第一数量为30,则将第二PRB编号20-31对30作取模运算,确定基于该通用资源分配信息在第三ARB集合内实际分配的PRB为0-1以及20-29。可选地,终端期望或假设基于该通用资源分配信息在第三ARB集合内实际分配的PRB相互之间不存在冲突,这里的冲突可以理解为至少一个PRB被实际分配超过一次,即被重复分配。
当终端不使用第三ARB集合对应的频域资源时,终端可以使用剩余第二ARB集合上的频域资源执行第一传输的收发。
当终端不期望出现这种情况时,由网络侧保证该通用资源分配信息与第三ARB集合兼容。
上述频域资源分配信息(包括独立指示的至少一套频域资源分配信息和通用资源分配信息)的设置,可以沿用NR中的相应机制,例如采用Bitmap方式(应用于PXSCH with resource allocation type 0并采用RBG粒度,PXSCH为PDSCH或PUSCH;以及应用于CORESET并采用6PRB组的粒度;这里的粒度,可以理解为Bitmap中每个比特对应的对象或范围)、Starting RB/RB number方式(应用于PUCCH/SRS/CSI-RS)或RIV方式(应用于PXSCH with resource allocation type 1)等。
