Description
本申请要求于2017年06月16日提交中国专利局、申请号为201710459573.4、申请名称为“一种通信方法、网络设备及终端设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及通信技术领域,特别涉及一种通信方法、网络设备及终端设备。
在由第三代合作伙伴项目(英文:the 3rd Generation Partnership Project,3GPP)制定的长期演进(英文:Long Term Evolution,LTE)***标准被认为是***无线接入***标准。现有LTE***中,基站配置一个***带宽,这个***带宽可以理解为一个载波带宽,基站和UE可以在该载波带宽的全带宽上进行数据传输。终端设备支持的带宽能力的最小值不小于载波带宽。LTE中,载波带宽可以是1.8MHz、3MHz、5MHz、10MHz、15MHz或20MHz,而UE的最小带宽能力为20MHz,因此,UE的工作带宽大于等于所述载波带宽。
随着通信***中场景和业务的多变性的需求,在下一代通信***中,例如:新空口(New Radio,NR)***,或者称之为第五代(5G)无线接入***,将支持更大的载波带宽,最大载波带宽例如可以是400MHz,而部分终端设备不具备支持这个最大载波带宽的能力,或者终端设备的业务需求不需要这么大的载波带宽。因此,在下一代通信***中,提出了一种两级指示用户资源分配的方法,首先在载波带宽中指示一个小于或等于用户支持的最大带宽的带宽作为用户设备的带宽部分(英文:bandwidth part,BP),第二步就是指示该带宽部分中具体为用户设备调度的资源块或资源块集合。比如,BP中包含为0-199个PRB,基站进一步指示终端设备在BP的0-199个PRB中的0-99个PRB用于传输数据。进一步的,如果终端设备支持多个BP,从传输块(英文:transimission block,TB)到BP的资源映射应该如何设计,成为亟需解决的技术问题。

以下,对本申请中的部分用语进行解释说明,以方便本领域技术人员理解。
1)本申请所述的“网络设备”,也称之为“接入网设备”,可以是gNB(gNode B),可以是普通的基站(例如WCDMA***中的基站(NodeB,NB),LTE***中的演进型基站(Evolutional NodeB,eNB或eNodeB),GSM或CDMA中的基站(Base Transceiver Station,BTS)),可以是新无线控制器(New Radio controller,NR controller),可以是集中式网元(Centralized Unit),可以是新无线基站,可以是射频拉远模块,可以是移动管理实体(mobile management entity,MME),可以是微基站,可以是分 布式网元(Distr ibuted Unit),可以是接收点(Transmission Reception Point,TRP)或传输点(Transmission Point,TP),还可以是云无线接入网络(Cloud Radio Access Network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者任何其它无线接入设备,但本申请实施例不限于此。
2)本申请所述的“终端设备”,可以是无线终端设备也可以是有线终端设备。无线终端设备可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为***、订户单元(Subscriber Unit,SU)、订户站(Subscriber Station,SS),移动站(Mobile Station,MB)、移动台(Mobile)、远程站(Remote Station,RS)、接入点(Access Point,AP)、远程终端(Remote Terminal,RT)、接入终端(Access Terminal,AT)、用户终端(User Terminal,UT)、用户代理(User Agent,UA)、终端设备(User Device,UD)、或用户装备(User Equipment,UE)。为方便描述,在本申请实施例中,终端设备和UE经常交替使用。
3)本申请所述的“带宽部分”,是指信道带宽中的一部分,也可以叫做“工作带宽(英文:operating bandwidth)”或者传输带宽,迷你BP(mini BP)、BP单元(BP Unit)、BP子带等,可以简称为BP,也可以简称为BWP,本申请实施例中不对带宽部分的名称以及简称进行具体限定。BP是指在数据传输时两级资源分配中第一步确定的带宽。可以为频域上一段连续的资源。例如,一个带宽部分包含连续的K>0个子载波;或者,一个带宽部分为N>0个不重叠的连续的资源块(Resource Block)所在的频域资源;或者,一个带宽部分为M>0个不重叠的连续的资源块组(Resource Block Group,RBG)所在的频域资源,一个RBG包括P>0个连续的RB。一个带宽部分与一个特定的***参数numerology集合相关,所述***参数集合包括子载波间隔和循环前缀(Cyclic Prefix,CP)的至少一种。
4)载波带宽:也可以叫做“信道带宽”或者“***带宽”,是由基站侧确定的一个小区级带宽。
5)本申请所述的“***参数numerology”,是指空口(英文:air interface)中的一系列物理层参数,具体实现时,可选的,一个BP可以对应一个numerology。numerology包括子载波间隔,时间单位的类型或循环前缀(英文:cyclic prefix,CP)类型等。以子载波间隔为例,若终端设备支持子载波间隔15kHz和30kHz,则基站可以为终端设备分配一个子载波间隔为15KHz的BP,和一个子载波间隔为30KHz的BP,终端设备根据不同的场景和业务需求,可以切换到不同的BP上,或者同时在 两个或更多BP上传输数据。当终端设备支持多个BP时,每个BP对应的numerology可以相同也可以不同。

另外,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
除非有相反的说明,本申请实施例提及“第一”、“第二”、“第三”以及“第四”等序数词用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。
接下来介绍本申请实施例的应用场景作简要介绍。
在无线通信***中,终端设备要向基站发送上行数据,或者基站向终端设备发送下行数据时,基站都要先从***支持的载波带宽中为终端设备分配部分带宽。在LTE中,当基站通过MIB配置一个***带宽后,基站则直接向终端设备指示在***带宽中用于传输数据的物理资源块,实现在基站和终端设备在该***带宽的全带宽上进行数据传输。
在本申请中,为了简便,“网络设备”和“基站”经常交替使用,“终端设备”和“用设备(英文:user equipment,UE)”经常交替使用,“***带宽”和“载波带宽”经常交替使用,但本申请技术人员应理解其应有之意。
接下来介绍本申请实施例的应用场景作简要介绍。
在无线通信***中,终端设备要向基站发送上行数据,或者基站向终端设备发送下行数据时,基站都要先从***支持的载波带宽中为终端设备分配BP。在LTE中,当基站通过主信息块(英文:master information block,MIB)配置一个***带宽后,基站则直接向终端设备指示在***带宽中用于传输数据的物理资源块,实现在基站和终端设备在该***带宽的全带宽上进行数据传输。

需要理解的是,本申请对于激活所述第一BP和所述第二BP的方式不作具体限定。上述第一信令或者第二信令可以承载在下行控制信息(英文:downlink control information,DCI)信令中,或者承载在高层信令中,例如无线资源控制(Radio Resource Control,RRC)信令,或媒体访问控制控制元素(Media Access Control Control Element,MAC CE),也可以承载在专用的信令中,本申请对此不作具体限定。本领域技术人员可以理解的是,网络设备可以向终端设备配置第三BP或者更多的BP,UE可以同时支持两个以上的被激活的BP,在本申请实施例中,为了简便,仅以第一BP和第二BP为例进行介绍。
S202、终端设备确定所述第一BP和所述第二BP。
具体地,终端设备根据所述网络设备的配置,确定所述第一BP和所述第二BP。
本申请实施例中,网络设备为终端设备配置并激活的BP的数量大于或等于2。其中,网络设备可能同时为终端设备配置多个BP,例如同时为终端设备配置所述第一BP和第二BP,且网络设备也可以同时激活第一BP和第二BP。或者,网络设备也可以在不同时刻为终端设备配置不同的BP,例如在第一时刻为终端设备配置并激活第一BP,在第二时刻为终端设备配置并激活第二BP,第一时刻可以位于第二时刻之前,或者第一时刻也可以位于第二时刻之后。
在一种具体的实施方式中,所述第一BP或者所述第二BP可以是终端设备在初始接入时网络设备为终端设备分配的BP。其中,如果第一BP或者第二BP是终端设备在初始接入时网络设备为终端设备分配的BP,那么第一BP或者第二BP可以是默认激活的。例如,网络设备可以向终端设备发送主信息块(英文:Master Information Block,MIB),终端设备接收MIB后,就可以根据MIB确定网络设备为终端设备分配并激活的第一BP。或者,终端设备根据预定义信息就可以知道网络设备为终端设备分配并激活的第一BP或者所述第二BP,例如终端设备通过盲检同步信号确定同步信号的频域资源,在根据预定义的关系确定第一BP或所述第二BP的频域资源。当网络设备为终端设备配置了多个BP时,所述多个BP中一个BP可以是终端设备在初始接入时网络设备为终端设备分配的BP,具体的配置方式,参见上述说明,不再赘述。
在一种具体的实施方式中,第一BP或者第二BP还可以是终端设备在接入网络之后网络设备为终端设备分配的BP。例如,网络设备可以向终端设备发送***信息块(英文:System Information Block,SIB),终端设备接收SIB后,就可以根据SIB确定网络设备为终端设备分配的所述第一BP或者所述第二BP。或者,网络设备可以向终端设备发送无线资源控制RRC信令,终端设备接收RRC信令后,根据该RRC信令就可以知道网络设备为终端设备分配并激活的所述第一BP或者所述第二BP。或者,网络设备也可以通过其他的信令来通知为终端设备分配并激活的所述第一BP或者所述第二BP,例如通过专用信令来通知为终端设备分配并激活的所述第一BP或者第二BP,本发明实施例对于网络设备如何通知第一BP或者第二BP不做限制。对于网络设备为终端设备配置多个BP的情况,参照上述说明,不再一一赘述。
在另一种具体的实施方式中,所述多个BP属于一个BP组,该BP组中所有的BP对应相同的numerology,则网络设备通过向终端设备发送配置信令,携带BP组的ID。所述终端设备中可以保存所述BP组的ID与所述BP组中所包括的所有BP的对应关系,即根据所述BP组的ID,所述终端设备即可以根据所述对应关系确定出所述BP组中所包括的所有BP。进一步的,确定了所述BP组中所包括的所有BP后,就可以确定所述BP组中包括的每个BP的大小和频域位置信息。
在另一种具体的实施方式中,所述BP组中每个BP对应一个BP索引,所述网络设备可以通过向终端设备发送的配置信令中指示BP组中每个BP的索引,终端设备根据接收到的BP的索引来确定所述多个BP。
所述配置信令例如可以是高层信令,例如RRC信令,MAC CE或者其它专用信令,本申请对此不作具体限定。
上述的方式进行例举,本申请对于BP的配置方式,不做具体限定,本申请技术人 员可以理解还可以通过其他方式配置BP,本申请不再一一赘述。
S203、所述网络设备向所述终端设备发送第一TB。
S204、所述终端设备接收所述网络设备发送的所述第一TB。
下面根据第一BP和第二BP是否对应相同的numerology,来具体阐述不同的情况下,所述网络设备向所述终端设备发送的TB如何在多个BP上进行资源映射。
在第一个具体的实施方式中,当所述第一BP和所述第二BP对应相同的numerology时,所述第一TB映射在所述第一BP和所述第二BP上。
具体地,所述第一BP和所述第二BP可以再频域上连续分布或者非连续分布,所述第一BP和所述第二BP在频域上可以重叠或者正交。对于BP非连续分布的情形,例如,在一种可能的方式中,在LTE和NR共存的网络场景中,如图3所示,一个终端设备的较大的BP可能被LTE占用,会产生两个频域上非连续的BP,即所述第一BP和所述第二BP。该第一BP和该第二BP具有相同的numerology。在另一种可能的方式中,所述被LTE占用的中间部分是公共的同步信号,但是该同步信号采用的numerology与所述第一BP和所述第二BP的numerology不同,所以需要将该第一BP和该第二BP聚合起来配置给所述终端设备使用。
对于BP连续分布的情形,例如,终端设备当前工作在第一BP,第一BP例如可以是终端设备初始接入时,网络设备为终端设备配置的BP,第一BP的带宽可能比较小。处于业务需求,终端设备在接入网络之后,需要配置更多的BP,如果继续使用第一BP来工作,则可能导致终端设备可用资源不足,因此,基站可能会给终端设备配置与第一BP在频域上连续分布的所述第二BP,以便终端设备能够更好的工作。或者,当终端设备的待传输业务类型改变时,网络设备也可以为终端设备重新分配BP,例如分配了该第二BP,以便匹配终端设备的业务类型需求。或者,网络设备需要进行***负载均衡时,也可以为终端设备重新分配BP,例如分配了该第二BP,以便有效地提升***资源利用率。
本领域技术人员可以理解,对于第一BP和第二BP的具体分布情况,本申请不做具体限定。
当网络设备向所述终端设备发送所述第一TB时,网络设备为所述第一BP和所述第二BP生成一个TB,即所述第一TB,并将所述第一TB的频域资源映射到该第一BP和第二BP上。
本申请中,对于具有相同numerology的多个BP来说,如果仍然采用一个TB对应一个BP的方法,则对应每个BP均需要配置一个DCI,因此,会导致资源的浪费,并且终端设备在检测每个DCI时,会消耗很多电量。通过本申请提供上述方案,第一BP和第二BP对应相同的numerology时,将所述第一TB在所述第一BP和所述第二BP上进行资源映射,则网络设备仅需要发送一个DCI。通过本申请的方案,能够有效减少发送DCI所带来的***开销,节省了***资源的同时,也降低了UE检测多个DCI所需的能耗。
本领域技术人员可以理解的是,如果网络设备还为终端设备配置并激活了第四BP,并且第四BP与所述第一BP和所述第二BP对应相同的numerology时,则所述第一TB在所述第一BP,所述第二BP以及所述第四BP上进行资源映射。同理,对于网络设备 为终端设备配置了更多BP的方案,以此类推,不再赘述。即,网络设备为终端设备配置了多个BP,该多个BP中的每个BP均对应相同的numerology,则网络设备向该终端设备发送的所述第一TB,在该多个BP所包括的所有BP上进行资源映射。
在另一个具体的实施方式中,当所述第一BP和所述第二BP对应相同的numerology时,所述第一BP的物理资源块PRB索引与所述第二BP的PRB索引在所述第一BP和所述第二BP所占的频域资源内连续编号。
参考图3,所述第一BP和所述第二BP的PRB索引统一编号。如图3所示,按照频域递增的方式,PRB索引的起始编号为所述第一BP的频域上最低的PRB的编号,结束编号为第二BP在频域上最高的PRB的编号。例如,第一BP的频域上最低的PRB的编号为0(即起始编号),第一BP的频域上最高PRB的编号为j,第二BP的频域上最低的PRB的编号为j+1,第二BP的频域上最高的PRB的编号为k,k为连续编号的结束编号。本申请中对于PRB编号的具体形式不作具体限定。
需要说明的是,对应于2个以上BP的方案,与图3所对应的方案类似,多个BP的PRB索引在多个BP所占的频域资源内连续编号。即PRB索引的起始编号为多个BP中起始BP的频域上最低的PRB的编号,结束编号为多个BP中最后一个BP的在频域上最高的PRB的编号。在起始编号和结束编号之间,按照频域递增的方式,进行连续编号。当然,本申请中,也可以按照频域递减的方式,起始BP为频域上最高的BP,起始编号为起始BP的频域上最高的PRB编号;结束BP为频域上最低的BP,结束编号为结束BP的频域上最低的PRB编号,在起始编号和结束编号之间,按照频域递减的方式,进行连续编号。
通过对具有相同的numerology的多个BP进行连续的PRB编号,有效节省了以小区带宽为粒度进行统一编号所导致的较大的资源分配开销。进一步的,对多个BP进行连续编号,有效避免了对单个BP独立编号时,用于指示BP内部资源配置信息的指示域的开销。
在另一个具体的实施方式中,当所述第一BP和所述第二BP对应相同的numerology时,在所述网络设备向所述终端设备发送所述第一TB之前,所述方法还包括:所述网络设备向所述终端设备发送第一控制信息。
下面具体阐述确定所述第一控制信息的频域位置的方式。
一个具体的实现方式中,所述网络设备向所述终端设备发送第一信息,所述终端设备接收所述第一信息。该第一信息用于指示所述第一控制信息的时频位置。
具体地,所述第一控制信息配置在所述第一BP中或者所述第二BP中,所述第一控制信息用于调度所述第一BP和所述第二BP。即所述第一BP和所述第二BP共享一个控制资源集合(CORESET),终端设备只需要按照所述第一信息的指示,即可确定所述第一控制信息的频域位置,即配置在哪个BP上,以及所对应的时域位置。因此,只需要监测所述第一BP或所述第二BP中配置的CORESET,即只需要监测两个BP中一个BP中配置的CORESET,而无需监测另外一个BP中配置的CORESET。对于多个BP的方案,以此类推,只需要监测多个BP中的一个BP中配置的CORESET,无需监测其它BP中配置的CORESET。因此,能够有效降低UE在检测每个BP中配置的CORESET所消耗的资源,有利于终端设备的节能。
所述第一信息可以承载在高层信令中,例如RRC信令,或MAC CE,也可以承载在专用的信令中,本申请对此不作具体限定。所述第一信息例如可以是承载多个0或者1标识信息的比特位,该比特位用于指示所述第一控制信息的频域位置。例如,第一信息由三个比特承载,当第一BP仅配置一个CORESET时,比特位对应的标识信息序列001可用于指示第一控制信息配置在第一BP上;当第一BP上配置多个CORESET时,比特位对应的标识信息序列001可以用于指示所述第一控制信息具体配置在所述第一BP的哪个CORESET中。所述第一信息,例如还可以是多个承载有0或者1标识信息的比特位,每1个比特位对应一个BP或者对应一个BP中所配置的CORESET,当每个比特置位为0或者1时,用于标识所述第一控制信息所对应的具体的BP或者具体的BP中的CORESET。例如,第一信息中包括三个比特,3个比特例如分别定义为L,M以及N比特,其中L,M以及N比特分别对应第一BP,第二BP以及第三BP。作为示例,当L比特置位为1,M以及N比特置位为0,表示第一控制信息配置在所述第一BP上,当L比特和N比特置位为0,而M比特置位为1,则表示所述第一控制信息配置在所述第二BP上。当然,也可以采用L比特置位为0,M以及N比特置位为1,来表示第一控制信息配置在所述第一BP上,当L比特和N比特置位为0,而M比特置位为1,则表示所述第一控制信息配置在所述第二BP上。本申请对于比特0或者比特1所表示的含义,不作具体限定。所述第一信息例如还可以是每个BP的索引。例如“0”表示第一控制信息配置在所述第一BP上,“1”表示所述第一控制信息配置在所述第二BP上。本申请对于第一信息的具体形式,不作具体限定。
另一个具体的实施方式中,一个BP可以对应多个CORESETs,该多个CORESETs的numerology是相同的,这样可以获得分集的效果,增加DCI传输可靠性,同时,也可以降低一个CORESET中,不同终端设备的DCI资源的冲突概率。对下行传输来说,一个BP的CORESETs的numerology可以和该BP相同,这样可以降低UE切换numerology的复杂度。对上行传输来说,由于上下行BP是独立配置的,对应的CORESET的numerology和BP的numerology可以不同,也可以相同。
如果多个BP具有相同的numerology,则该多个BP可以配置相同的CORESET组,换言之,该多个BP中每个BP配置相同的CORESET组,或者一个BP组对应1个CORESET组,该一个BP组中可以由多个BP组成。此时,如果该CORESET组对应的DCI是指向相同的TB,则多个BP采用相同的TB映射。其中,该CORESET组对应的DCI是指UE需要检测的DCI。如果该多个CORESET对应的DCI是指向不同的TB,比如非相干联合传输时,则该多个BP采用不同的TB映射。
具有相同numerology的多个BP所配置的CORESET组中,多个BP配置的多个CORESET组中至少有一个公共的CORESET,该公共的CORESET用于默认承载所述第一控制信息。此时,可选的,网络设备可以不需要向终端设备指示所述第一控制信息的时频位置。
在一个具体的实施方式中,所述第一控制信息中包括用于指示第一混合自动重传请求(英文:hybrid automatic repeat request,HARQ)进程的指示信息。在本申请中,HARQ进程的指示信息用于指示所传输的TB的进程号,该进程号用于UE在接收数据时,对初传和重传的数据进行HARQ合并,以得到具体的合并增益。在本实施方式中, 两个BP对应1个TB,进一步对应唯一的HARQ进程。
在另一个具体的实施方式中,当所述第一BP和所述第二BP对应相同的numerology时,在所述网络设备向所述终端设备发送第一传输块TB之前,所述方法还包括:所述网络设备根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小。所述终端设备根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小。
下面具体说明根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小的两种可能的情形。
情形一,当所述第一BP和所述第二BP在频域上没有重叠时,所述网络设备根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小,具体包括:所述网络设备根据所述第一BP和所述第二BP的带宽的和来确定为所述第一TB分配的RBG的大小。所述终端设备根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小,具体包括:所述终端设备根据所述第一BP和所述第二BP的带宽的和来确定为所述第一TB分配的RBG的大小。例如,第一BP的带宽为M,第二BP的带宽为N,则第一BP和所述第二BP的带宽的和为B,则B=M+N。
情形二,当所述第一BP和所述第二BP在频域上有重叠时,则所述网络设备根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小,具体包括:所述网络设备根据所述第一BP和所述第二BP在频域上所跨的带宽来确定为所述第一TB分配的RBG的大小。则所述终端设备根据所述第一BP的带宽和所述第二BP的带宽确定为所述第一TB分配的RBG的大小,具体包括:所述终端设备根据所述第一BP和所述第二BP在频域上所跨的带宽来确定为所述第一TB分配的RBG的大小。例如:所述第一BP和所述第二BP在频域上所跨的带宽为F,第一BP的带宽为W,第二BP的带宽为U,所述第一BP和所述第二BP重叠部分的带宽为S,则F=W+U-S。例如,第一BP和第二BP在频域上有重叠,第一BP为10MHz,第二BP为20MHz,第一BP和第二BP重叠的部分为5MHz,则所述第一BP和所述第二BP在频域上所跨的带宽为25MHz。此时,终端设备根据25MHz的带宽来确定为所述第一TB分配的RBG的大小。
下面结合图4A和4B对于RBG的大小(下文中简称RBG size)进行具体说明。
借用LTE中对于RBG Size的定义,对某一个带宽范围,会定义对应的RBG的大小,如下表所示:
表1:Type 0资源配置RBG size vs.下行***带宽
其中,在本实施例中,需要采用第一BP和第二BP的联合带宽来代替表中的***带宽,以确定对应的RBG的大小。其中,RBG的编号不跨BP,如图4A示,RBG的大小为4,第一BP有10个RB,第二BP有7个RB,RBG的编号如图所示,其中,对于最后一个RBG来说,RBG中所包括的RB的数量可能小于4,因此,RBG2仅包含有2个RB, RBG4仅包含有3个RB。或者,RBG的编号跨BP,如图4B所示,RBG的大小为4,第一BP有10个RB,第二BP有7个RB,RBG的编号如图4B所示,其中,RBG2包含有第一BP的两个RB和第二BP的两个RB,对于最后一个RBG来说,RBG中所包括的RB的数量可能小于4,因此,RBG4仅包含有1个RB。其中,上述的第一BP和第二BP的联合带宽,对应上述情形一中第一BP和第二BP的带宽的和;或者对应上述情形二中第一BP和第二BP在频域上所跨的带宽。为了便于表述,在本申请中用第一BP和第二BP的联合带宽来指代上述两种情形。
本申请中所述的RBG的大小,例如可以是LTE中所定义的1,2,3,4,也可以是NR***中所讨论的数值,例如,2,4,8,16。RBG的大小可以是如LTE中定义的每个RBG中包含的虚拟资源块(英文:virtual resource block,VRB)的数量。也可以是NR***中所可能的定义,例如每个RBG中包含的资源单位的数量,所述资源单位例如可以是资源元素(英文resource element,RE),或者RB,或者VRB,或者PRB或者其它的单位,本申请对此不作具体限定。在LTE中,网络设备会通过下行共享物理信道(英文:physical downlink shared channel,PDSCH)向终端设备传输TB,PDSCH是在下行子帧的数据区域上传输。下行PDSCH资源基于VRB进行分配,VRB与PRB有一定的对应关系。终端设备上保存有带宽与RBG size的对应关系,当终端设备确定了所述第一BP和第二BP的联合带宽后,会根据第一BP和第二BP的联合带宽确定为所述第一TB分配的RBG的大小。最终确定传输所述第一TB时,所占用的PRB的时频位置。在NR***中,网络设备会通过与PDSCH功能相同或者近似的物理信道向终端设备传输TB。传输TB时,物理信道的资源是基于VRB或者与VRB有相同或者近似定义的资源块进行分配。
在一个具体的实施方式中,参考图5,当所述第一BP和所述第二BP对应相同的numerology时,所述第一BP和所述第二BP在同一个BP组中。可选的,所述BP组中由所述第一BP和所述第二BP组成。此时,在S202之前,所述方法还包括:所述网络设备向所述终端设备发送第二信息,所述终端设备接收所述第二信息。所述第二信息用于指示所述BP组的标识符ID,所述BP组中所包括的所有BP对应相同的numerology,所述BP组的ID被所述终端设备用于确定所述第一BP和所述第二BP。
一种具体的实施方式中,所述终端设备中可以保存所述BP组的ID与所述BP组中所包括的所有BP的对应关系,即根据所述BP组的ID,所述终端设备即可以根据所述对应关系确定出所述BP组中所包括的所有BP。进一步的,确定了所述BP组中所包括的所有BP后,就可以确定所述BP组中包括的每个BP的大小和位置信息。
在另一个具体的实施方式中,所述第二信息中可以进一步包括用于指示所述BP组中所包括的每个BP的索引的指示信息,根据该指示信息确定所述BP组中所包括的每个BP的索引,进而确定所述网络设备为所述终端设备所配置的所述BP组中所包括的所有BP。可选的,当所述BP组中仅包括所述第一BP和所述第二BP时,则上述指示信息仅包括用于指示第一BP的索引的第一指示信息和用于指示第二BP的索引的第二指示信息。可选的,当所述BP组由第一BP,第二BP以及第四BP组成时,则上述指示信息包括所述第一指示信息,所述第二指示信息以及用于指示第四BP的索引的第三指示信息。当BP组由更多的BP组成时,以此类推,不再赘述。
在一个具体的实施方式中,所述BP组的ID还被所述终端设备用于确定所述BP组中包括的每个BP的带宽。具体地,所述终端设备根据所述BP组的ID可以确定所述BP组所包括的所有BP的配置信息,根据每个BP的配置信息确定每个BP的位置信息和大小,进而确定所述BP组的每个BP的带宽。
在一个具体的实施方式中,所述网络设备根据所述BP组中包括的所有BP的带宽确定为所述第一TB分配的RBG的大小。同理,所述终端设备根据所述BP组中包括的所有BP的带宽确定为所述第一TB分配的RBG的大小。关于RBG的大小以及如何确定为所述第一TB分配的RBG的大小的相关说明,参见上文具体描述,此处不再赘述。
在一个具体的实施方式中,所述网络设备还为所述终端设备配置并激活了第三BP,,所述第三BP对应的numerology与所述BP组中每个BP所对应的numerology不同,则所述方法200还包括:所述网络设备向所述终端设备发送第二TB,所述终端设备接收所述网络设备发送的所述第二TB,所述第二TB映射在所述第三BP上。即在本申请中,在多个BP对相同的numerology时,网络设备对应给多个BP生成一个TB,即所述第一TB,该第一TB在多个BP上进行资源映射。在多个BP对应不同numerology时,网络设备对每个具有不同numerology的BP分别生成一个TB,每个TB分别在每个BP上进行资源映射。例如,所述第一BP和所述第二BP对应相同的numerology,属于同一个BP组中,则第一TB映射在所述第一BP和所述第二BP上。所述第三BP与所述第一BP以及所述第二BP对应不同的numerology,则网络设备生成第二TB,所述第二TB映射在所述第三BP中。第三BP中会配置一个控制信息,用于调度所述第三BP,所述终端设备会检测所述第三BP中配置的所述控制信息。
在另一个具体的实施方式中,参考图6,当所述第一BP和所述第二BP对应不同的numerology时,所述方法还包括以下步骤:
所述网络设备向所述终端设备发送第三TB。所述终端设备接收所述网络设备发送的所述第三TB。其中,所述第一TB在所述第一BP上进行资源映射,所述第三TB映射在所述第二BP上。
通过本申请提供的上述方案,当第一BP和所述第二BP对应不同的numerology时,则采用不同的TB对应不同的BP的方法,有效解决来了UE在同时支持多个不同的BP的情况下如何进行TB资源映射的问题。
在一个具体的实施方式中,当所述第一BP和所述第二BP对应不同的numerology,所述第一BP的PRB索引在所述第一BP内进行独立编号,所述第二BP的PRB索引在所述第二BP内独立编号。
所述第一BP的PRB索引在所述第一BP内进行独立编号,是指按照频域递增的方式,在第一BP所占的频域资源内,对第一BP内的PRB进行连续编号。所述第一BP的PRB索引的起始编号为所述第一BP的频域上最低的PRB的编号,结束编号为所述第一BP的频域上最高的PRB的编号。起始编号例如可以是0,结束编号例如可以是m,m为大于0的整数。同理,第二BP的PRB索引在所述第二BP内进行独立编号的相关说明,不再赘述。也可以按照频域递减的方法,进行连续编号,具体说明参见上文,此处不再赘述。如果网络设备为所述终端设备配置了多个分别对应不同numerology的BP,则每个BP均在各自BP内进行独立编号,编号方式参见上述说明,此处不再赘述。
通过在BP内独立编号,有效节省了以小区带宽为粒度进行统一编号,所导致的较大的资源分配开销。
在一个具体的实施方式中,当所述第一BP和所述第二BP对应不同的numerology时,在所述网络设备向所述终端设备发送所述第一TB和所述第三TB之前,所述方法还包括:
所述网络设备向所述终端设备发送第二控制信息和第三控制信息,所述终端设备接收所述第二控制信息和所述第三控制信息。所述第二控制信息用于调度所述第一BP,所述第三控制信息用于调度所述第二BP。
关于第三控制信息,第四控制信息的具体说明参见上述第一控制信息的说明,此处不再赘述。
在一个具体的实施方式中,当所述第一BP和所述第二BP对应不同的numerology,在所述网络设备向所述终端设备发送所述第一TB和所述第三TB之前,所述方法还包括:所述网络设备根据所述第一BP的带宽确定为所述第一TB分配的RBG的大小,所述网络设备根据所述第二BP的带宽确定为所述第三TB分配的RBG的大小。相应的,所述终端设备接收所述第一TB和所述第三TB之后,所述终端设备根据
关于RBG的大小的相关说明参见上文中关于RBG大小的具体说明,此处不再赘述。
在一个具体的实施方式中,当所述第一BP和所述第二BP对应不同的numerology,在所述网络设备向所述终端设备发送所述第一TB和所述第三TB之前,所述方法还包括以下步骤。
步骤A.所述网络设备为所述第一TB分配第二HARQ进程,并向所述终端设备发送第三信息,所述第三信息用于指示第二HARQ进程的ID。
所述第三信息可以承载在所述所述二控制信息中,或者承载在高层信令,例如RRC信令,MAC CE或者其它专用的信令中,本申请对此不作具体限定。
步骤B.网络设备为所述第三TB分配第三HARQ进程,并向所述终端设备发送第四信息,所述第四信息用于指示第三HARQ进程的ID。
所述第四信息可以承载所述所述三控制信息中,或者承载在高层信令,例如RRC信令,MAC CE或者其它专用的信令中,本申请对此不作具体限定。
