Description

资源分配的方法和装置 技术领域
本申请涉及通信领域,更具体地,涉及通信领域中资源分配的方法和装置。
背景技术
在长期演进(Long Term Evolution,LTE)***中,网络设备可以通过下行控制信息(Downlink Control Information,DCI)中包括的资源指示信息来指示资源,进而,使得终端设备在该资源上发送上行数据。
在LTE的短传输时间间隔(shortened Transmission Time Interval,sTTI)的传输机制中,引入了短资源块组(shortened resource block group,sRBG)。其中,sTTI传输机制中调度资源的最小粒度是短资源块组。
但是,在sTTI场景下,网络设备通过sTTI中的DCI调度上行数据时,会造成超过10%的资源不能被调度,造成***资源浪费。
因此,亟需提供一种技术,能够解决上述问题,减少***资源的浪费。
发明内容

所述Q为***带宽对应的资源单元的个数,所述Q为大于1的整数,所述X为大于2的整数,
其中,所述L1种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽中的Q个连续的资源单元中除第S+1个资源单元以外的资源单元,所述S为X的整数倍。
所述X是每种资源分配方案对应的资源中包括的至少一个资源单元组中每个资源单元组包括的资源单元的个数。
因此,本申请实施例提供的资源分配的方法,提供了L种资源分配方案,可以使得终端设备使用该L种资源分配方案传输上行数据;其中,该L种资源分配方案L1种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽的Q个连续的资源单元中除第S+1个资源单元外的资源单元,S是X的整数倍,X是每种资源分配方案对应的资源中包括的至少一个资源单元组中每个资源单元组包括的资源单元的个数,那么,在需要 为sPUCCH分配资源和使得被调度的资源需要满足质因子约束的情况下,该L1种资源分配方案可以为上行数据的传输分配较多的资源,较好地满足质因子约束,从而,降低带宽损失,减少***资源的浪费。
在一种可能的实现方式中,所述L种资源分配方案还包括L2种资源分配方案,所述L2种资源分配方案与L2种资源指示值一一对应,所述L2种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽中的Q个连续的资源单元中的第S+1个资源单元,其中,

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信***,例如:全球移动通讯(Global System of Mobile communication,GSM)***、码分多址(Code Division Multiple Access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)***、LTE频分双工(Frequency Division Duplex,FDD)***、LTE时分双工(Time Division Duplex,TDD)、通用移动通信***(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信***、未来的第五代(5th Generation,5G)***或新无线(New Radio,NR)等。
本申请实施例中的终端设备可以指用户设备、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、个人数字处理(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,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备,该网络设备可以是全球移动通讯(Global System of Mobile communication,GSM)***或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***中的基站(NodeB,NB),还可以是LTE***中的演进型基站(Evolutional NodeB,eNB或eNodeB),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未来演进的PLMN网络中的网络设备等,本申请实施例并不限定。
图1是应用于本申请实施例的资源分配的通信***的示意图。如图1所示,该通信***100包括网络设备102,网络设备102可包括多个天线例如,天线104、106、108、110、112和114。另外,网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持 计算设备、卫星无线电装置、全球定位***、PDA和/或用于在无线通信***100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工(Frequency Division Duplex,FDD)***中,例如,前向链路118可利用与反向链路120所使用的不同频带,前向链路124可利用与反向链路126所使用的不同频带。

在给定时间,网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。
具体而言,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。
此外,该通信***100可以是公共陆地移动网络(Public Land Mobile Network,PLMN)网络或者D2D网络或者M2M网络或者其他网络,图1只是举例的简化示意图,网络中还可以包括其他网络设备,图1中未予以画出。
下面,在描述本申请实施例之前,首先对本申请实施例涉及到的技术术语进行简单介绍。
1、TTI和sTTI
在本申请实施例中,通信***100所使用的用于无线通信的资源在时域上可以划分为多个TTI,TTI是目前通信***(例如,LTE***)中的普遍使用的参数,是指在无线链路中调度数据传输的调度单位。
一个传输期间包括N个符号(symbol),其中,N为正整数。本申请不限定传输期间的时间长度,即不限定N的取值,例如:一个传输期间可以是一个子帧(subframe),一个时隙(slot),一个迷你时隙(mini-slot),或者,一个短传输期间(STD,short Transmission Duration)/短传输时间间隔(sTTI,short Transmission Time Interval)。
在无线通信***中,时延是影响用户体验的重要因素之一。不断出现的新业务,例如 与车联网相关的业务等对时延提出越来越高的要求。因此,对于现有的LTE***,基于TTI为一个子帧的传输机制已经无法满足低时延业务的需求。因而,基于sTTI的传输机制应运而生,能够有效地减少组包和解调编制码的时间,进而达到减少物理层空口时延的目的。
在LTE***中,一个slot由7或6个符号(symbol)组成。一个子帧为1ms(毫秒),由14或12个符号组成。
在NR(New Radio)***中,一个slot由14或12个符号组成。NR***中,一个子帧为1ms,可以包括1,2,4,8,16或32个slot。
sTTI可以包括2,3或7个符号。
在本申请实施例中,对一个符号的时间长度不做限制。例如,针对不同的子载波间隔,一个符号的长度可以有所不同。
2、资源粒子(resource element,RE)
RE也可以称为资源元素。在时域上可以对应一个符号,在频域上可以对应一个子载波。在本申请实施例中,RE可以是资源单元的一例。
3、资源块(resource block,RB)
一个RB在频域上占用

个连续的子载波。其中,

可以等于12。本申请实施例中,可以仅从频域资源上来定义RB,也就是说,不限制RB在时域上占用的时域资源数量。在本申请实施例中,RB可以是资源单元的又一例。
4、符号(symbol)
符号是时域资源的最小单位。本申请实施例对一个符号的时间长度不做限制。针对不同的子载波间隔,一个符号的长度可以有所不同。符号可以包括上行符号和下行符号,作为示例而非限定,上行符号例如可以称为单载波频分多址(Single Carrier-Frequency Division Multiple Access,SC-FDMA)符号或正交频分多址(Orthogonal Frequency Division Multiplexing,OFDM)符号;下行符号例如可以称为OFDM符号。需要说明的是,若后续技术引入新的上行多址方式或下行多址方式,仍然可以称为符号。本申请对于上行多址方式和下行多址方式不做限制。在本申请实施例中,符号可以是资源单元的再一例。
5、资源单元
资源单元可用于作为资源在时域、频域或时频域占用的资源的计量单位。在本申请实施例中,资源单元例如可以包括符号、RE、RB、子载波等,本申请对此不做限定。
6、资源单元组
资源单元组也可用于作为资源在时域、频域或时频域占用的资源的另一种计量单位。在本申请实施例中,资源单元组包括至少一个资源单元,例如,一个资源单元组包括4个资源单元,在资源单元为RB的情况下,一个资源单元组包括4个RB。
在本申请实施例中,资源单元可以作为资源在频域上占用的资源的计量单位,因此,本申请实施例中涉及到的连续的资源单元的描述可以理解为在频域上连续的资源单元。
现有技术中,网络设备可以通过下行控制信息(Downlink Control Information,DCI)中包括的资源分配信息来指示资源,可以使得终端设备在该资源上发送上行数据。
在短传输时间间隔(shortened Transmission Time Interval,sTTI)的传输机制中,相比 于传统的1ms的TTI中的1个DCI可以调度1ms的资源,sTTI的传输机制中的1个DCI中的资源指示信息只能调度2~3个符号的资源,因此,在sTTI的传输机制中需要更多的DCI,增加了资源开销。
为了解决上述问题,在sTTI的传输机制中引入了短资源块组(shortened resource block group,sRBG),即,上文所述的资源单元组的一种。其中,一个sTTI中包括4个资源块RB。这样,1个DCI中可以调度的资源粒度由原来的1个RB变为1个sRBG,(即,4个RB),进而,可以通过调度sRBG来调度较多符号的资源。
但是,在这种通过sRBG调度资源的方式中,网络设备只能以sRBG为单位调度资源,使得该网络设备仅能调度一部分的资源,不能有效地为终端设备配置较多的资源,会造成超过10%的资源不能被调度,造成***资源浪费。
下面,针对上述技术中浪费***带宽的原因做一简单说明。
一方面,在LTE***中,上行频带不仅用于发送上行数据,还要用于发送上行控制信息。因此,通常,上行频带不仅给用于承载上行数据短物理上行共享信道(shortened Physical Uplink Shared Channel,sPUSCH)分配RB,也会给用于承载上行控制信息的短物理上行控制信道(shortened,Physical Uplink Control Channel,sPUCCH)分配一定数量的RB。
另一方面,在上行资源分配中,网络设备为终端设备调度的资源的RB的个数需满足下列条件:
Figure PCTCN2018082058-appb-000036
其中,
Figure PCTCN2018082058-appb-000037
表示用于上行传输的RB的个数,a 2、a 3和a 5为非负整数。
也就是说,网络设备为终端设备调度的资源的RB的个数的质因子仅包含质因子2、3、5。因为,上行数据传输比下行数据传输要多做一步离散傅里叶变化DFT,而RB的个数所包含的质因子,会直接影响DFT的复杂度,当质因子仅包含2、3、5时,DFT可以通过较简单的方式实现。为了描述简便,我们在下文中称这一约束为质因子约束。
例如,以20MHz带宽为例,若需要为sPUCCH分配资源,则sPUSCH占用的最多的资源只能起始于sRBG#1(即,RB#4),结束于sRBG#23(即,RB#95),共占用92个RB,其中,sRBG#0和sRBG#24分配给(s)PUCCH。同时,在质因子约束下,小于或等于92的最大整数为80,即,一个sPUSCH最多能够占用的资源是80个RB。
对于1ms TTI传输机制而言,一个PUSCH最多能够占用的资源是96个RB(例如,RB#2~RB#97),因此,相比于TTI传输机制中的PUSCH,sTTI传输机制中的sPUSCH最多会有16.7%的带宽损失,进而带来容量损失。
表1为在sTTI传输机制中,不同带宽对应的带宽损失。
表1
  10MHz 15MHz 20MHz
sTTI最大的可用RB 40 64 80
1ms TTI最大的可用RB 48 72 96
带宽损失 16.7% 11.1% 16.7%
从表1可以看出,在sTTI传输机制下,除了5MHz的带宽,其余带宽都会有不同程度的带宽损失。
因此,为了解决上述问题,本申请实施例提供了一种资源分配的方法,有助于减少***带宽的损失。
为了便于理解本申请实施例,首先,结合图2,介绍与本申请实施例相关的资源分配方案。
同时,为了描述方便,以资源单元为RB为例,对本申请实施例的资源分配方案进行说明。
在现有的上行LTE***中,网络设备有五种类型的资源分配方案,本申请实施例涉及的资源分配方案是类型0的资源分配方案。
在类型0的资源分配方案中,网络设备会终端设备分配的资源为一段连续的RB。因此,每一种资源分配方案可以由资源长度(即,连续的RB的个数)和起始位置这两个参数唯一确定。
如图2所示为资源的资源长度和始位置之间的关系的示意图。如图2所示,横坐标表示资源的起始位置,纵坐标表示资源占用的RB的个数。
假设,用于上行传输的RB的个数为N,网络设备以RB为单位调度资源,则:
若资源的资源长度为1个RB,则资源的起始位置可能为RB#0~RB#N-1中的任一个,共有N种可能的选择;
若资源的资源长度为2个RB,则资源的起始位置可能为RB#0~RB#N-2中的任一个,共有N-1种可能的选择;
以此类推,若资源的资源长度为k个RB,则资源的起始位置可能为RB#0~RB#N-k中的任一个,共有N-k+1种可能的选择;
若资源的资源长度为N个RB,则资源的起始位置只能为RB#0,共有1种可能的选择。
综上所述,用于上行传输的资源的资源分配方案可以有

种,占用
Figure PCTCN2018082058-appb-000039
个比特来表示一种资源分配方案。
基于上述
Figure PCTCN2018082058-appb-000040
种资源分配方案,可以通过
Figure PCTCN2018082058-appb-000041
种资源指示值(Resource Indication Value,RIV)表示,每种资源指示值对应一种资源分配方案,每种资源分配方案包括至少一个RB。
资源指示值RIV与资源分配方案之间的关系(为了便于理解与区分,即为关系#1)可以满足如下条件:
Figure PCTCN2018082058-appb-000042
则RIV=N(x-1)+y;
Figure PCTCN2018082058-appb-000043
RIV=N(N-x+1)+(N-1-y)。
其中,x表示资源占用的RB的个数(或者说,资源长度),y表示该资源的起始位置的索引。
因此,基于上述关系#1,终端设备基于预设规则,从资源分配信息中获取该资源指示值后,就可以计算出该资源占用的RB的个数和资源的起始位置,从而确定该资源。
下面,结合图3至图6,详细说明本申请实施例的资源分配的方法。
图3所示为本申请一实施例的资源分配的方法200的示意***互图。该方法的执行主体可以为终端设备。下面,对方法200中的各个步骤进行详细说明。
在步骤S210中,网络设备发送资源分配信息,该资源分配信息用于指示资源#1(即,第一资源的一例)。
具体而言,该资源分配信息中包括资源指示值,该资源指示值用于指示该资源#1,该终端设备基于该资源分配信息获得该资源指示值,基于该资源指示值确定该资源#1。
其中,该终端设备基于该资源指示值确定该资源#1的方式可以参考上文所述的资源指示值和资源分配方案的关系(即,关系#1)。即,该终端设备基于该资源指示值RIV和该关系#1,确定该资源#1占用的资源单元(例如,RB)的个数和起始位置(即,起始资源单元)。
应理解,在本申请实施例中,该网络设备以资源单元组为粒度调度该资源#1,也就是说,该资源#1中包括至少一个资源单元组,其中,一个资源单元组中包括X个资源单元,X为大于1的整数。
需要说明的是,当该网络设备以资源单元组调度该资源#1时,上文描述的
Figure PCTCN2018082058-appb-000044
其中,Q为***带宽对应的连续的资源单元的个数。
如前所述,该资源分配信息可以承载于DCI中,那么,为了能够在DCI中获取该资源分配信息,在步骤S210之前,该方法还包括:
网络设备向终端设备发送指示信息#1,该指示信息#1用于指示小区所使用的上行***带宽。
进而,该终端设备根据该上行***带宽,确定在DCI中该资源分配信息占用的比特数。
进而,基于预设规则,从该DCI中获得对应比特数的资源分配信息包括的资源指示值。
在一种可能的实现方式中,该指示信息#1可以承载于高层信令中,或,该指示信息#1可以为高层信令。
例如,该指示信息#1可以承载于***信息中,该***信息指示的上行***带宽为20MHz,对应100个RB,即,Q=100,若X=4,则
Figure PCTCN2018082058-appb-000045
即20MHz的***带宽对应25个资源单元组,那么,由公式
Figure PCTCN2018082058-appb-000046
可得,在DCI中,该资源分配信息的资源指示值占用的比特数为
Figure PCTCN2018082058-appb-000047
在S220中,该终端设备根据该资源分配信息和偏移量,确定资源#2(即,第二资源的一例),其中,该偏移量表示资源#1的起始位置相对于该资源#2的起始位置所偏移的资源单元的个数M,该偏移量是预定义的或由高层信令配置的。
也就是说,该终端设备可以根据该资源#1和偏移量,确定新的资源(即,资源#2)。
其中,该资源#1的起始位置表示该资源#1的起始资源单元,同理,该资源#2的起始位置表示该资源#2的起始位置。
该偏移量表示的是连续的资源单元的个数M。
在本申请实施例中,该终端设备根据该资源分配信息和偏移量确定该资源#2的具体方式可以如下:
根据该资源#1的起始位置和该偏移量,确定该资源#2的起始位置;
根据该资源#2的起始位置和该资源#1对应的资源单元的个数,确定该资源#2。
例如,假设,上行***带宽为20MHz,对应的Q=100,X=4,M=2,资源单元为RB, 基于关系式#1计算得到的资源#1的起始位置为第5个RB(即,RB#4),占用的RB的个数为92个RB,则资源#1的结束位置为第96个RB(即,RB#95),对应地,该资源#1包括23个资源单元组。那么,该资源#2的起始位置为第7个RB(即,RB#6),占用的RB的个数依然为92个RB,该资源#2的结束位置为第98个RB(即,RB#95)。
那么,在确定该资源#2后,在步骤S230中,该终端设备在该资源#2上传输上行数据。
综上所述,在该网络设备以资源单元组为单位调度该资源#1的情况下,该资源#1的起始位置的索引只能是X的整数倍,或者说,该资源#1的起始位置只能是***带宽中的第S+1个资源单元,其中,S是X的整数倍。例如,如上文所述,若X=4,资源单元为RB,该资源#1的起始位置的索引只能是RB#0、RB#4等,对应地,RB#0是***带宽中的第1个RB,RB#4是***带宽中的第5个RB。
图4所示为***带宽为20MHz的资源,Q=100,那么,资源#1的起始位置仅可以是图中黑色阴影的RB。
通过引入偏移量,可以适当改变用于传输上行数据的资源的位置,使得改变后得到的资源#2的起始位置的索引不再是X的整数倍,或者说,使得该资源#2的起始位置不再是***带宽中的第S+1个资源单元,可以是其他起始位置的资源。例如,继续以X=4,资源单元为RB为例,若M=2,则在资源#1的起始位置的索引是RB#0的情况下,该资源#2的起始位置的索引可以是RB#2,即,***带宽中的第3个RB,同理,在资源#1的起始位置的索引是RB#4的情况下,该资源#2的起始位置的索引可以是RB#6,即,***带宽中的第7个RB。
继续如图4所示,基于该资源#1和该偏移量确定的资源#2的起始位置可以是除黑色阴影的其余RB中的一个RB。
继续如图4所示,以资源单元为RB为例,如前所述,在20MHz***带宽的情况下,若需要为sPUCCH分配资源,在现有技术中,sPUSCH占用的最多的资源只能起始于资源单元组#1(即,RB#4),结束于资源单元组#23(即,RB#95),共占用92个RB,资源单元组#0和资源单元组#24分配给sPUCCH。同时,在质因子约束下,小于或等于92的最大整数为80,即,一个sPUSCH最多能够占用的资源是80个RB。应理解,图中所示的80个RB的位置仅为示意性说明,本申请实施例不做任何限定。
在本申请实施例中,通过引入偏移量,由于调整了用于传输上行数据的资源的位置,可以使得调整后得到的资源#2的起始位置的索引不再只是***带宽中的第S+1个资源单元,可以是任意起始位置的资源,能够为上行数据的传输分配较多的资源,可以较好地满足质因子约束,从而,降低带宽损失。
如图5所示,假设,M=2,若需要为sPUCCH分配资源,可以使得sPUSCH占用的最多的资源起始于RB#2,结束于sRB#97,共占用96个RB,将RB#0、RB#1、RB#98和RB#99分配给sPUCCH。同时,由于96=96=2 5·3 1,满足质因子约束。这样,相比于TTI传输机制,在sTTI传输机制中,网络设备也可以调度96个RB。
因此,本申请实施例提供的资源分配的方法,在网络设备通过资源单元组调度资源的情况下,通过引入偏移量,可以有效地调整被调度的资源的起始位置,使得被调度的资源的起始位置可以是***带宽中除第S+1个资源单元以外的资源单元,其中,S是X的整数倍,X是一个资源单元组中包括的资源单元的个数,那么,在需要为sPUCCH分配资源和 使得被调度的资源需要满足质因子约束的情况下,本申请实施例可以为上行数据的传输分配较多的资源,较好地满足质因子约束,从而,降低带宽损失。
此外,通过预定义或高层信令配置该偏移量的方式,可以有效地减少DCI的开销,在用于传输上行数据的资源不变的情况下,可以有效地提高DCI的可靠性。
在一种可能的实现方式中,1≤M≤(X-1)。
因此,通过限定偏移量M的大小,可以使得尽量多的资源用于PUSCH传输,而非被PUCCH占用,进而提升PUSCH可以调度的最大资源的个数。
在本申请实施例中,可以在sTTI传输机制的***中,针对不同***带宽,引入表2中的偏移量,从而可以解决带宽损失问题。
表1
  10MHz 15MHz 20MHz
偏移量 1 1 2
sTTI最大的可用RB 40 64 80
1ms TTI最大的可用RB 48 72 96
带宽损失 0% 0% 0%
对于10MHz的***带宽,引入1RB的偏移量,用户可以使用RB#1~RB#48的资源传输上行数据,为sPUCCH分配RB#0和49,以用于传输上行控制信息,和表1比较而言,多利用大约16%的资源;
对于15MHz的***带宽,引入1RB的偏移量,用户可以使用RB#1~RB#72,为sPUCCH分配RB#0、RB#73和RB#74,以用于传输上行控制信息,和表1比较而言,多利用了大约11%的资源;
对于20MHz,引入2RB offset,用户可以使用RB#2~RB#97,为sPUCCH分配RB#0、RB#1、RB#98和RB#99,以用于传输上行控制信息,和表1比较而言,多利用了大约16%的资源。
在一种可能的实现方式中,在本申请实施例中,资源指示值RIV、该资源#2的起始位置RB START、资源单元组的个数P与该偏移量M满足以下关系:
Figure PCTCN2018082058-appb-000048
的情况下,RIV=N(P-1)+(RB START-M)/X;或,
Figure PCTCN2018082058-appb-000049
的情况下,RIV=N(N-P+1)+[N-1-(RB START-M)/X];
其中,
RIV表示该资源分配信息中包括的用于指示该资源#1的资源指示值,
Figure PCTCN2018082058-appb-000050
该Q为***带宽对应的资源单元的个数,该Q和所述X都为大于1的整数,
(RB START-M)可以被X整除;
该P表示该资源#2中包括的资源单元组的个数,该P个资源单元组中每个资源单元组包括X个资源单元,1≤P≤[N-(RB START-M)/X]。
即,该终端设备获取该资源分配信息中的资源指示值后,根据该资源#1的资源指示值和偏移值,基于上述关系(为了便于区分与理解,记为关系#2)计算出该资源#2的起 始位置RB START和资源单元组的个数P,从而计算出该资源#2的具***置。
例如,20MHz带宽下,Q=100,X=4,N=25,偏移值M=2,资源分配信息中的资源指示值为74,根据关系#2计算出该资源#1的起始位置为RB#0,资源单元组的个数P=24,再根据资源#1的起始位置RB#0和偏移值,确定资源#2的起始位置RB START=2,之后根据该资源#2的起始位置RB START和资源单元组的个数P,从而计算出该资源#2的具***置为RB#2~RB#97。
图6所示为本申请另一实施例的资源分配的方法300的示意***互图。该方法的执行主体可以为终端设备。下面,对方法300中的各个步骤进行详细说明。
在步骤S310中,网络设备发送资源分配信息,所述资源分配信息包括资源指示值#1(即,第一资源指示值的一例)。
其中,该资源指示值#1用于指示一种资源分配方案(例如,第一资源分配方案)。
在步骤S320中,终端设备根据该资源指示值#1,确定对应于该资源指示值#1的资源分配方案#1,
其中,该第一资源分配方案属于L种资源分配方案,该L种资源分配方案包括L1种资源分配方案,该L1种资源分配方案与L1种资源指示值一一对应,
Figure PCTCN2018082058-appb-000051
Figure PCTCN2018082058-appb-000052
该Q为***带宽对应的资源单元的个数,该Q为大于1的整数,该X为大于2的整数,
其中,该L1种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽中的Q个连续资源单元中除第S+1个资源单元以外的资源单元,该S为X的整数倍。
X是每种资源分配方案对应的资源中包括的至少一个资源单元组中每个资源单元组包括的资源单元的个数。
具体而言,网络设备可以配置L种资源分配方案,L种资源分配方案可以通过L种资源指示值指示,每种资源指示值指示一种资源分配方案。其中,L种资源分配方案中的L1种资源分配方案与L1种资源指示值对应,并且,该L1种资源分配方案中的每种资源分配方案对应的资源的起始位置为Q个连续资源单元中除第S+1个资源单元外的资源单元。
在一种可能的实现方式中,该L种资源分配方案还包括L2种资源分配方案,该L2种资源分配方案与L2种资源指示值一一对应,该L2种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽中的Q个连续的资源单元中的第S+1个资源单元,其中,
Figure PCTCN2018082058-appb-000053
也就是说,该L种资源分配方案可以包括两种类型的资源分配方案,下面,分别对两种资源分配方案进行详细说明。
L2种资源分配方案
该L2种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽中的Q个连续的资源单元中的第S+1个资源单元,其中,
Figure PCTCN2018082058-appb-000054
由上文的描述可知,当用于上行传输的RB的个数为N,网络设备以RB为单位调度资源时,用于上行传输的资源的资源分配方案可以有
Figure PCTCN2018082058-appb-000055
种;同理,当用于上行传输的RB的个数为Q,网络设备以资源单元组为单位调度资源时,用于上行传输的资源的资源分配 方案也可以有
Figure PCTCN2018082058-appb-000056
其中,
Figure PCTCN2018082058-appb-000057
因此,基于上述理由,
Figure PCTCN2018082058-appb-000058
并且,该L2资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽的Q个连续的资源单元中的第S+1个资源单元。
继续以图4为例,其中,***带宽为20MHz、X=4,资源单元为RB,图4中黑色阴影的RB即为L2种资源分配方案中的任一个资源分配方案的可能的起始位置。
具体来说,若S=0,则,S+1=1,则L2种资源分配方案中的一种资源分配方案的资源的起始位置为100个RB中的第1个RB(即,RB#0);若S=4,则,S+1=5,则L2种资源分配方案中的另一种资源分配方案的资源的起始位置为100个RB中的第5个RB(RB#4);若S=8,则,S+1=9,则L2种资源分配方案中的一种资源分配方案的资源的起始位置为100个RB中的第9个RB(RB#4),等等。
如前所述,该L2种资源分配方案与L2种资源指示值一一对应(记为对应关系#1A),那么,终端设备可以通过该资源指示值#1和该对应关系#1A,确定对应于该资源指示值#1的资源分配方案。
这里,需要说明的是,该对应关系#1A可以通过公式计算,也就是说,在该对应关系#1A中,资源分配方案对应的资源与资源指示值满足如下条件:
Figure PCTCN2018082058-appb-000059
的情况下,RIV=N(x 1-1)+y;或,
Figure PCTCN2018082058-appb-000060
的情况下,RIV=N(N-x 1+1)+(N-1-y 1)。
其中,
Figure PCTCN2018082058-appb-000061
x 1表示资源分配方案对应的资源中包括的资源单元组的个数,y 1表示资源分配方案对应的资源中的起始资源单元组的索引。
L1种资源分配方案
该L1种资源分配方案中的每种资源分配方案对应的资源的起始位置为Q个连续资源单元中除第S+1个资源单元外的资源单元。
也就是说,继续以图4为例,L1种资源分配方案中的每种资源分配方案对应的资源是除图4中黑色阴影的RB以外的RB,即,该L1种资源分配方案能够调度现有技术所不能调度的资源。
在一种可能的实现方式中,该L1种资源分配方案可以***预定义的,也可以是网络设备通过高层信令通知的。本申请实施例不限于此。
在本申请实施例中,为了使得终端设备能够基于资源分配信息中的资源指示值确定资源分配方案,将该L种资源分配方案与L种资源指示值一一对应,其中,该L1种资源分配方案与L1种资源指示值对应,该L2种资源分配方案与L2种资源指示值对应。
这样,该终端设备可以基于该资源分配信息包括的资源指示值#1,确定对应的资源分配方案(即,资源分配方案#1)。
因此,本申请实施例提供的资源分配的方法,提供了L种资源分配方案,可以使得终端设备使用该L种资源分配方案传输上行数据;其中,该L种资源分配方案L1种资源分配方案中的每种资源分配方案对应的资源的起始位置为***带宽的Q个连续的资源单元中除第S+1个资源单元外的资源单元,S是X的整数倍,X是每种资源分配方案对应的资源中包括的至少一个资源单元组中每个资源单元组包括的资源单元的个数,那么,在需要为sPUCCH分配资源和使得被调度的资源需要满足质因子约束的情况下,该L1种资源分 配方案可以为上行数据的传输分配较多的资源,较好地满足质因子约束,从而,降低带宽损失。因此,当该终端设备确定的第一资源分配方案属于该L1种资源分配方案时,可以有效地降低带宽损失。
