具体实施方式
为了便于理解本发明实施例,先介绍以下技术点:
(1)NR中的下行频域资源分配:
在NR中,有两种类型的资源块(Resource Block,RB),包括物理资源块(Physical Resource Block,PRB)和虚拟资源块(Virtual Resource Block,VRB)。对于带宽大小为
Figure PCTCN2021091860-appb-000001
的下行物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的频域资源,一共有
Figure PCTCN2021091860-appb-000002
个VRB和PRB,编号从0到
Figure PCTCN2021091860-appb-000003
在PDSCH的资源分配中,有两种VRB到PRB的映射方式:非交织(Non-interleaved)和交织(interleaved)。
NR中的PDSCH的频域资源分配通过DCI的频域资源分配(Frequency Domain Resource Assignment,FDRA)域来指示,即PDSCH的VRB在下行BWP中的索引值。
支持两种资源分配类型:类型0(Type 0)(非连续频域资源分配)和类型1(Type 1)(连续频域资源分配)。
对于DCI 1_0只支持Type 1的频域资源分配类型,有1比特(bit)指示VRB到PRB的映射方式。
对于DCI 1_1可支持Type 0或Type 1的频域资源分配类型,可以高层配置为Type 0或Type 1,也可以高层配置为动态切换(Dynamic Switch)模式并通过DCI 1_1中FDRA域的高1bit指示资源分配类型。如果高层配置不支持VRB到PRB映射的交织模式,或者高层配置只支持Type 0资源分配类型,DCI 1_1为非交织VRB到PRB映射,无VRB到PRB映射指示比特,否则通过VRB到PRB映射比特指示非交织或交织方式。
Type 0和Type 1的资源分配方法见下述NR中的上、下行频域资源分配方案。
(2)关于两种资源分配类型:Type0和Type1的介绍:
Figure PCTCN2021091860-appb-000004
Type0:
将资源分配的目标上/下行BWP内的资源块划分成多个资源块组(Resource Block Group,RBG),每个RBG对应于一个由最多P个连续VRB构成的集合,P基于高层参数配置(指示使用表1中的哪一列,是配置1(Configuration 1)还是配置2(Configuration 2))、目标上/下行BWP内包含的资源块数目。
表1:标称RBG大小P(Nominal RBG size P)
Figure PCTCN2021091860-appb-000005
DCI格式(Format)0_1/1_1的FDRA域使用位图(Bitmap)的方式,指示目标上行BWP中的各个RBG是否分配给终端。Bitmap中的各个比特与目标上/下行BWP中的各个RBG一一对应,当Bitmap中的某个比特设置为1时,指示对应的RBG分配给终端,即此RBG中包含的所有资源块都分配 给终端。
DCI Format 0_0/1_0不支持上行资源分配类型0。
Figure PCTCN2021091860-appb-000006
Type 1
假设VRB集合中的起始VRB编号为RB start(在目标上行BWP内的局部编号),连续分配的VRB数目为L RBs,则基于下列公式计算资源指示值(Resource Indication Value,RIV):
如果

Figure PCTCN2021091860-appb-000008
否则,

上述

为目标上行BWP中包含的VRB数目,L RBs≥1并且不能超过

在DCI Format 0_0/0_1/1_0/1_1的“FDRA”域中指示RIV,从而向终端指示分配的VRB集合。
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外,说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一,例如A和/或B,表示包含单独A,单独B,以及A和B都存在三种情况。
在本发明实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本文所描述的技术不限于长期演进型(Long Time Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,并且也可用于各种无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、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 Frequency-Division Multiple Access,SC-FDMA)和其他系统。
术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access,UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access,WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication,GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra Mobile Broadband,UMB)、演进型UTRA(Evolution-UTRA,E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System,UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project,3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。
下面结合附图介绍本发明的实施例。本发明实施例提供的一种频域资源分配方法及设备可以应用于无线通信系统中。参考图1,为本发明实施例提供的一种无线通信系统的架构示意图。如图1所示,该无线通信系统可以包括:网络设备11和终端12,终端12可以记做UE12,终端12可以与网络设备11通信(传输信令或传输数据)。在实际应用中上述各个设备之间的连接可以为无线连接,为了方便直观地表示各个设备之间的连接关系,图1中采用实线示意。
本发明实施例提供的网络设备11可以为基站,该基站可以为通常所用的基站,也可以为演进型基站(evolved node base station,eNB),还可以为5G系统中的网络设备(例如,下一代基站(next generation node base station,gNB)或发送和接收点(transmission and reception point,TRP))等设备。
本发明实施例提供的终端12可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer,UMPC)、上网本或者个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等。
参见图2,本发明实施例还提供一种频域资源分配方法,该方法的执行主体为终端,包括:步骤201和步骤202。
步骤201:接收调度多个载波、小区或带宽部分(或者称为激活BWP)的第一下行控制信息;
步骤202:根据所述第一下行控制信息,被调度的每个载波、小区或带宽部分的频域资源分配所需的比特数和每个比特对应的频域资源组,得到终端在所述多个载波、小区或带宽部分上的频域资源。
需要说明的是,在下面的示例中是以频域资源为RB,频域资源组为RBG,频域资源组大小为RBG size为例进行的介绍,但并不限于此。
比如,根据第一DCI调度的多个载波、小区或BWP的RB总数,或者根据各个载波、小区或BWP的RB数,确定的RBG size,根据该RBG size分别按照每个载波、小区或者BWP进行Type 0频域资源分配指示,或者对多个载波、小区或BWP进行Type 0频域资源分配的联合指示。
在一些实施方式中,在步骤202之前,图2所示的方法还可以包括:确定所述多个载波、小区或带宽部分的频域资源组大小;根据所述频域资源组大小,得到所述被调度的每个载波、小区或带宽部分的频域资源分配所需的比特数和/或每个比特对应的频域资源组。
进一步地,所述多个载波、小区或带宽部分的频域资源组大小是网络侧配置的;或者,根据频域资源数与频域资源组大小的对应关系和第一数量,得到多个载波、小区或带宽部分的频域资源组大小;
其中,所述第一数量包括以下一项或多项:
(1)多个载波的频域资源总数;
多个载波的频域资源总数是指各个载波的频域资源数之和。
(2)多个小区的频域资源总数;
多个小区的频域资源总数是指各个小区的频域资源数之和。
(3)多个带宽部分的频域资源总数;
多个带宽部分的频域资源总数是指各个带宽部分的频域资源数之和。
(4)多个载波中至少部分载波中的最大频域资源数或最小频域资源数;
(5)多个小区中至少部分小区中的最大频域资源数或最小频域资源数;
(6)多个带宽部分中至少部分带宽部分中的最大频域资源数或最小频域资源数。
下面结合方案1~方案3,介绍在一个DCI调度多个载波、小区或者BWP的场景下,终端如何减小Type 0频域资源分配开销:
方案1:根据第一DCI调度的多个载波、小区或激活BWP的RB总数,或者N个载波、小区或激活BWP中最大/最小的RB数,以及RB数和RBG size的对应关系(需要说明的是,该对应关系与调度单载波的对应关系不同,比如,引入新的RB size范围(range),或者新的RBG size),确定RBG size P(包含的RB数目),作为每个载波、小区或激活BWP进行频域资源分配指示的粒度(即bitmap中的1bit代表的RB个数),计算各载波、小区或激活BWP的频域资源分配所需的比特数和/或每个比特对应的频域资源组。
此时,频域资源分配指示域的大小为∑Ni,Ni为基于第i个载波、小区或激活BWP中的RBG size P确定的频域资源分配位图大小,i为自然数。
可以理解的是,上述RBG size P可以是网络侧配置的,例如通过无线资源控制(Radio Resource Control,RRC)配置。
方案2:根据第一DCI调度的各个载波、小区或者激活BWP的RB数分别确定每个载波、小区或激活BWP的RBG size,根据预定义或RRC配置的缩放系数,或者根据第一DCI调度的载波、小区或激活BWP个数,对确定的RBG size进行缩放(scaling),分别作为每个载波或激活BWP进行频域资源分配指示的粒度(即bitmap中的1bit代表的RB个数),计算各载波、小区或激活BWP频域资源分配所需的比特数和/或每个比特对应的频域资源组。
此时,频域资源分配指示域的大小为∑Ni,Ni为基于第i个载波、小区或激活BWP中的RBG size P确定的频域资源分配位图大小,i为自然数。
在方案2中的一些实施方式中,在步骤202之前,图2所示的方法还可 以包括:
根据被调度的每个载波、小区或带宽部分的频域资源数,得到所述被调度的每个载波、小区或带宽部分的频域资源组大小;对所述被调度的每个载波、小区或带宽部分的频域资源组大小的进行缩放处理(scaling);根据缩放后的所述被调度的每个载波、小区或带宽部分的频域资源组大小,得到所述被调度的每个载波、小区或带宽部分的频域资源分配所需的比特数和/或每个比特对应的频域资源组。
方案3:根据第一DCI调度的多个载波、小区或者激活BWP的RB总数或者N(N大于等于1)个载波中最大或最小RB数,以及RB数和RBG size的对应关系(需要说明的是,该对应关系与调度单载波的对应关系不同,比如,引入新的RB size range,或者新的RBG size)确定RBG size,然后根据该RBG size对多个载波、小区或者BWP进行联合的Type 0频域资源分配指示,比如,分别位于两个BWP上的连续分裂(fragmented)RBG共享1比特进行指示。
可以理解的是,上述RBG size可以是网络侧配置的,例如通过RRC配置。
在一些实施方式中,在所述多个载波或小区或带宽部分为所述终端分配的Type 0频域资源,包括以下任意一项:
(1)在所述多个载波上联合为所述终端分配的Type 0频域资源;
(2)在所述多个小区上联合为所述终端分配的Type 0频域资源;

(4)在所述多个载波中每个载波为所述终端分配的Type 0频域资源;
(5)在所述多个小区中每个小区为所述终端分配的Type 0频域资源;
(6)在所述多个带宽部分中每个带宽部分为所述终端分配的Type 0频域资源。
在本发明实施例中,在一个DCI调度多个载波、小区或者BWP的场景下,可以在保持相同调度灵活性的同时,减少控制信道资源开销,提高控制信道的解调性能与系统的有效覆盖范围。

方案3:根据第一DCI调度的多个载波、小区或者激活BWP的RB总数或者N(N大于等于1)个载波中最大或最小RB数,以及RB数和RBG size的对应关系(需要说明的是,该对应关系与调度单载波的对应关系不同,比如,引入新的RB size range,或者新的RBG size)确定RBG size,然后根据该RBG size对多个载波、小区或者BWP进行联合的Type 0频域资源分配指示,比如,分别位于两个BWP上的连续分裂(fragmented)RBG共享1比特进行指示。
可以理解的是,上述RBG size可以是网络侧配置的,例如通过RRC配置。

参见图4,本发明实施例还提供一种频域资源分配方法,该方法的执行主体为终端,具体步骤包括:步骤401和步骤402。
步骤401:接收调度多个载波、小区或带宽部分的第二下行控制信息;
步骤402:根据所述第二下行控制信息中的频域资源分配域,得到终端在多个载波、小区或带宽部分上的频域资源;
其中,所述频域资源分配域包括:频域资源分配位图对应的索引,或者,频域资源集合的索引,所述频域资源集合满足预设条件。

在方案a的一些实施方式中,所述方法包括:
接收网络设备针对被调度的每个载波、小区或带宽部分配置的资源指示值列表,所述索引表示频域资源分配位图在所述资源指示值列表中的位置。可以理解的是,索引可以是隐式包含的,配置一个RIV列表,频域资源分配位图在该RIV列表中的位置为索引。
在方案a的一些实施方式中,所述频域资源分配域的大小与所述被调度的每个载波、小区或带宽部分配置的资源指示值列表中频域资源分配位图的个数相关。

在方案b的一些实施方式中,所述索引表示所述频域资源集合按照对应bitmap的长度从小到大或从大到小的排列顺序。
也就是说,在方案b中,通过满足预设条件的频域资源分配位图个数确定频域资源分配域的大小,并将满足预设条件的频域资源分配位图进行编号得到位图的索引,终端接收到的DCI中的索引对应到相应的频域资源分配位图, 得到多个载波、小区或带宽部分分配的频域资源。即通过协议规定索引->位图->频域资源的映射关系,终端和网络都使用该映射关系进行接收DCI获取多个载波、小区或带宽部分分配的频域资源,或发送DCI调度相应的多个载波、小区或带宽部分的频域资源。
在本发明实施例中,通过合理限制频域资源分配的候选,这样在一个DCI调度多个载波、小区或者BWP的场景下,可以在保持相同调度灵活性的同时,减少控制信道资源开销,提高控制信道的解调性能与系统的有效覆盖范围。

也就是,在方案a中,RRC配置所需bitmap码点对应的RIV列表,DCI通过bitmap码点对应的索引进行频域资源指示;
(1)如果对调度的一个或多个载波、小区或BWP进行单独RRC配置RIV列表,则根据各个配置RIV列表的码点数目计算每个载波、小区或BWP调度所需FDRA域的大小;

在方案b的一些实施方式中,所述索引表示所述频域资源集合按照对应bitmap的长度从小到大或从大到小的排列顺序。
在本发明实施例中,通过合理限制频域资源分配的候选,这样在一个DCI调度多个载波、小区或者BWP的场景下,可以在保持相同调度灵活性的同时,减少控制信道资源开销,提高控制信道的解调性能与系统的有效覆盖范围。
下面结合实施例一、实施例二和实施例三介绍本发明的实施方式。
实施例一:
当DCI调度I个载波、小区或BWP时(I>1),第i个载波或BWP的RB数为Ni,计算调度的I个载波、小区或BWP的RB总数为∑Ni,则调度第i个载波、小区或BWP的RBG size相同,根据计算的∑Ni值和RRC配置的configuration按照表2进行确定RBG size。
需要说明的是,表2相对于调度单个载波的配置表格不同,可以协议预定义新的表格,比如,新的表格中配置新的BWP size,新的RBG size,或者不同的RB范围(range)分割。
根据确定的RBG size分别在第i个载波、小区或BWP得到每个比特对应的RBG和所需比特数大小,在DCI中进行分别指示。
表2:RBG size
Carrier Bandwidth Part Size Configuration 1 Configuration 2
1–72 2 4
72–144 4 8
145–275 8 16
276–550 16 16
可选的,该RBG size可通过RRC显式配置。
实施例二:
当DCI调度I个载波、小区或BWP时(I>1),第i个载波、小区或BWP的RB数为Ni,根据Ni和RRC配置的configuration按照表2进行确定RBG size得到RBGi,根据预定义或者RRC配置的缩放系数对RBGi进行scaling,比如scaling系数为K,得到第i个载波、小区或BWP的新RBG size RBG’i=K*RBGi,各自根据RBG’i分别在第i个载波、小区或BWP得到每个bit对应的RBG和所需比特数大小,在DCI中进行分别指示。
实施例三
RRC配置所需bitmap码点(频域资源分配位图)对应的表格,DCI通过bitmap码点对应的索引进行频域资源指示。例如,对于一个BWP的RB数为20,RBG size为2,需要10bit进行Type 0频域资源分配的指示,RRC配置bitmap码点与索引的对应关系,则DCI中使用2bit指示该FDRA值。
表3:bitmap码点与索引(Index)的对应关系。
Index Type 0 FDRA
0 1010101010
1 0101010101
2 1101001001
3 1001001011
实施例四:
限制调度的频域RB需要大于BWP RB总数的一半,满足该条件的Type  0 FDRA值进行排序,并按照排序的index进行指示。例如对于一个BWP的RB数为10,RBG size为2,则满足条件的Type 0 FDRA为00111,01101,01110,01111,10011,10101,10110,10111,11001,11010,11011,11100,11101,11110,11111等共15种可能,需要用4bit进行指示,例如0000代表的FDRA值为00111。
