Description

一种资源分配指示的方法、设备及系统
本申请要求于2016年4月1日提交专利局、申请号为PCT/CN2016/078367、发明名称为“一种资源分配指示的方法、设备及系统”的申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域,尤其涉及的是一种资源分配指示的方法、设备及系统。
背景技术
长期演进(英文全称:Long Term Evolution,英文简称:LTE)系统中,基站调度终端设备在免许可频谱资源上发送上行数据,基站通过控制信道向终端设备发送调度信息,如资源分配信息、调整编码方式等,使得终端设备通过检测控制信道中承载的调度信息进行下行数据的接收或上行数据的发送,使得终端设备在发送数据时,将资源块(英文全称:Resource Block,英文简称:RB)作为资源调度单位进行调度与分配。基站为终端设备分配信道资源时,一般将频域上1个或连续的多个RB分配给一个UE,或者将频域上不连续的2个RB集合分配给一个UE,每个RB集合包含频域上1个或连续的多个RB。但由于终端设备在免许可频谱资源上发送数据时,需满足免许可频谱规定的限制条件:终端设备在每兆赫兹(英文全称;Mega Hertz英文简称:MHz)内的发送功率不能超过10分贝毫瓦(英文全称:deciBel Milliwatt,英文简称:dBm)或者7dBm,故采用现有的资源分配方式,终端设备的总发送功率受到为终端设备分配的频域上连续的RB个数的限制,导致免许可频谱的覆盖范围减小。
现有机制中,为同时满足上述限制条件和不减少免许可频谱的覆盖范围,基站将上行载波带宽中2个以上不连续的资源块集合分配给终端设备,使得终端设备可以使用每个资源块集合发送上行数据时,一定程度上可以实现使用上述限制条件下的最大发射功率,以及提高免许可频谱的覆盖范围。
但在资源指示给终端设备时,根据目前免许可频谱的法规,基站不支持将不连续的资源块集合的具体资源信息指示给终端设备,基站只能将带宽中第一个资源集合中的某一资源块的信息指示给终端设备,默认与该资源块属于同一个各行交错(Interlace)的资源块都分配给终端设备,其次,也不适用于多个终端设备之间频分复用免许可频谱的上行资源。
发明内容
本发明实施例提供了一种资源分配指示的方法、设备及系统,能够解决现有技术中无法将免许可频谱的资源分配的具体信息指示给终端设备的问题。
本发明实施例的第一方面提供一种资源分配指示的方法,所述方法包括:
终端设备向接入网设备发送资源请求,所述终端设备获取接入网设备发送的第一指示信息;
所述终端设备根据所述第一指示信息确定目标资源,并在所述目标资源上发送上行数据;
所述目标资源包括M个基础资源单元中被分配给所述终端设备的资源块,所述M个基础资源单元中每个基础资源单元中被分配的资源块位置与第一资源块集合中资源块的第一频域位置对应,所述第一资源块集合中资源块的第一频域位置为第二资源块集合中资源块的第二频域位置移位后的频域位置,其中M为正整数。实现准确获取用于发送上行数据的目标资源的资源位置。
可选的,所述移位为循环移位,所述第一指示信息满足以下之一:
所述第一指示信息用于指示所述第二资源块集合中资源块的第二频域位置和所述循环移位的移位值T,其中T为整数;
所述第一指示信息用于指示所述第一资源块集合中资源块的第一频域位置。使得终端设备能够精确的确定目标资源的资源位置,减少计算时间。
在一些可能的设计中,所述第一资源块集合满足:
所述第一资源块集合中第k个资源块的频域位置和M个资源块的频域位置对应,所述第一资源块集合中第k个资源块的频域位置fk对应的第m个资源块为所述M个基础资源单元中的第m个基础资源单元中频域位置为(fkm)的资源块,其中,Δm为与第m个基础资源单元对应的资源映射参考值,k、m均为正整数,Δm为整数,1<k≤K,1<m≤K,K为所述一个基础资源单元包括的资源块个数。
可选的,在(fkm)>K时,所述第一资源块集合中第k个资源块的频域位置fk对应的所述第m个基础资源单元中的资源块为频域位置(fkm)在所述第m个基础资源单元中循环移位后的频域位置对应的资源块。
在一些可能的设计中,所述第一资源块集合满足:
所述第一资源块集合中第x个资源块的频域位置和M个资源块的频域位置对应,所述M个资源块分别为所述M个基础资源单元中每个基础资源单元中和所述第x个资源块的频域位置相同的资源块,其中,x正整数,1<x≤K。
实现在满足功率频谱密度的限制条件下,提高终端设备的发送功率。
在一些可能的设计中,终端设备侧和接入网设备侧都预先配置参考资源集合组,用于终端设备确定用于发送上行数据的目标资源,所述参考资源块集合组至少包括一个参考资源块集合。所述第二资源块集合为参考资源块集合组中第一类型的资源块集合,所述第一类型的资源块集合包括L个资源块组,所述资源块组为一个资源块,或者包括频域上相邻的至少两个资源块,所述L个资源块组中的各资源块组之间在频域上互不相邻;
所述L个资源块组中的第V1个资源块组中的第一个资源块的频域位置对应一个基础资源单元的第

个资源块,其中1≤V1≤P1;
所述L个资源块集合中的第V2个资源块组中的第一个资源块的频域位置对应所述一个基础资源单元中的第
Figure PCTCN2016082095-appb-000002
个资源块,其中P1+1≤V2≤L;
其中,L、P1、P2、V1、V2及K均为正整数,L≥2,P1≥1,P2=L-P1,K为所述一个基础资源单元包括的资源块个数。能够提高终端设备确定目标资源的准确性,以及减少计算资源位置的时间。
在一些可能的设计中,针对第一资源块集合,所述L个资源块组还满足:按频域增序,所述L个资源块组中前P1个资源块组各自包括的资源块的个数均为M1,所述L个资源块组中后P2个资源块组各自包括的资源块的个数均为M2,其中,M1>M2,M1和M2均为正整数。将L个资源块组中各自包括的资源块的个数尽量均匀化,可以使终端设备发送的上行信息的峰均比值尽量低,提高终端设备发送功率的效率。
在一些可能的设计中,若所述L个资源块组中包括的资源块的总数为奇数,则M1-M2=1。由于L个资源块组中各自包括的资源块的个数差异最小化,可以实现终端设备被允许发送的最大发送功率不受所包含的资源块个数较多 的资源块组的限制。
在一些可能的设计中,所述第一资源块集合为第一类型的资源块集合时,所述循环移位的移位值T为集合[0,1,...l1]中的任一个,或者为集合[l2,l2+1,...l3]中的任一个,其中,
Figure PCTCN2016082095-appb-000003
所述移位值T为相对于资源块组,按频域增序方向的循环移位。有益效果移位值T为所述集合范围内的值,可保证L个资源块组中的资源块循环移位后形成的资源块组仍然是L个。
在一些可能的设计中,考虑到同一个基础资源单元中的资源块只分给一个终端设备时,会剩余一些资源块,可以将剩余的资源块分配给其他终端设备,实现多个终端设备频分复用资源的目的。具体可以是,第二终端设备侧配置的参考资源块集合组还包括第二类型的资源块集合,所述第二类型的资源块集合包括L个资源块组,所述资源块组为一个资源块,或者为频域上相邻的至少两个资源块,所述L个资源块组中的各资源块组之间在频域上互不相邻;
所述第二类型的资源块集合包括L个资源块组,所述L个资源块组中的第V3个资源块组中的第一个资源块的频域位置对应所述一个基础资源单元的第
Figure PCTCN2016082095-appb-000004
个资源块,其中,1≤V3≤L;
其中L≥2,K为所述一个基础资源单元包括的资源块个数。实现多个终端设备之间的频分复用。
在一些可能的设计中,对于第二类型的资源块集合满足a&b两种情况之一:
a、第二类型的资源块集合包括的L个资源块组中前P3个资源块组各自包括的资源块的个数均为M3,所述L个资源块组中后P4个资源块组各自包括的资源块的个数均为M4,其中,M3和M4均为正整数,P3≥3,P4=L-P3,M3>M4。将L个资源块组中各自包括的资源块的个数尽量均匀化,可以使终端设备发送的上行信息的峰均比值尽量低,提高终端设备发送功率的效率。
可选的,与所述第二类型的资源块集合对应的循环移位的移位值T2满足:
所述移位值T2为集合[0,1,...l1]中的任一个,或者为集合[l2,l2+1,...l3]中的任一个,其中,
Figure PCTCN2016082095-appb-000005
所述循环移位为按频域增序方向的循环移位。可保证资源块分配的均匀性的同时,还保证L个资源块组中的资源块不分散。
b、所述L个资源块组中的各资源块组包括的资源块的个数均为M5,与所述第二类型的资源块集合对应的循环移位的移位值T满足:
所述移位值T2为集合[0,1,...l1]中的任一个,其中,
Figure PCTCN2016082095-appb-000006
,M5为正整数;
所述循环移位为按频域增序方向的循环移位。移位值T为所述集合范围内的值,可保证L个资源块组中的资源块循环移位后形成不同的资源块集合。
在一些可能的设计中,所述第二资源块集合中资源块的个数O1满足
Figure PCTCN2016082095-appb-000007
时,所述第二资源块集合对应的循环移位的移位值只有一种;
和/或,
所述第二资源块集合中资源块的个数O1为奇数时,所述第二资源块集合对应的循环移位的移位值只有一种,其中,O1为正整数,K为所述一个基础资源单元包括的资源块个数。
在一些可能的设计中,对于第一资源块集合与M个基础资源单元的关系如下:
所述第一资源块集合中第t1个资源块的频域位置对应一个基础资源单元中的第U1个资源块,所述第二资源块集合中第t2个资源块的频域位置对应所述第i个基础资源单元中的第U2个资源块,满足U1=mod(t1,K),U2=mod(U1+T,K),其中,T为所述循环移位的移位值,K为一个基础资源单元所包括的资源块的个数,t1、t2、U2、T为大于0的正整数。实现终端设备只需要知晓一个基础资源单元中被分配的资源块即第一资源块集合的频域位置,终端设备便可以根据预设的规则计算出其他基础资源单元中被分配的资源块的频域位置,有效减少终端设备的计算步骤和提高确定资源位置的准确性,一定程度上减少终端设备的功耗。
以下第二方面提供的实施例,主要从接入网设备的角度来描述。

在一些可能的设计中,所述移位为循环移位,所述第一指示信息满足以下之一:
所述第一指示信息用于向所述终端设备指示所述第二资源块集合中资源块的第二频域位置和所述循环移位的移位值T1;

在一些可能的设计中,对于上述第一类型的资源块集合,L个资源块组满足:按频域增序,所述L个资源块组中前P1个资源块组各自包括的资源块的个数均为M1,所述L个资源块组中后P2个资源块组各自包括的资源块的个数均为M2,其中,M1>M2,M1和M2均为正整数。将L个资源块组中各自包括 的资源块的个数尽量均匀化,可以使终端设备发送的上行信息的峰均比值尽量低,提高终端设备发送功率的效率。
在一些可能的设计中,根据终端设备的数据量需求,若所述L个资源块组中包括的资源块的总数为奇数,则M1-M2=1。由于L个资源块组中各自包括的资源块的个数差异最小化,可以实现终端设备被允许发送的最大发送功率不受所包含的资源块个数较多的资源块组的限制。

所述接入网设备从所述M个基础资源单元中为另一终端设备分配目标资源,并将第二指示信息发送至该终端设备,分配给两个终端设备的资源在频域上不重叠,从而实现频分复用和提高小区的覆盖范围和资源利用率。
在一些可能的设计中,对于第二终端设备,可以使用本发明中的某种类型的资源块集合,例如上述第一类型的资源块集合,也可以结合使用现有机制中的某种类型的资源块集合,例如。使用所述参考资源快集合组中的第二种类型的资源块集合,第二种类型的资源块集合满足:

虽然在前述背景技术部分以LTE系统为例进行了介绍,但本领域技术人员应当知晓,本发明不仅仅适用于LTE系统,也可以适用于其他无线通信系统,例如全球移动通信系统(英文全称:Global System for Mobile Communication,英文简称:GSM),移动通信系统(英文全称:Universal Mobile Telecommunications Systemc,英文简称:UMTS),码分多址接入(英文全称:Code Division Multiple Access,英文简称:CDMA)系统,以及新的网络系统等。下面以LTE系统为例进行具体实施例的介绍。
其中,需要特别说明的是,本发明实施例涉及的终端设备,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。无线终端可以经无线接入网(英文全称:Radio Access Network,英文简称:RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,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(英文全称:Personal Communication Service,英文简称:PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop,英文简称:WLL)站、个人数字助理(英文全称:Personal Digital Assistant,英文简称:PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站 (Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、终端设备、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
由于按照免许可频谱的现有规则,在基站将为终端设备分配的资源指示给终端设备时,无法明确将分配的多个不连续的资源块组指示给终端设备,为解决上述技术问题,本发明实施例主要提供以下技术方案:
1、接入网设备和终端设备两侧均预先配置传输规则,传输规则包括按照参考资源块集合组选择资源。
参考资源块集合组中的资源块集合包括的资源块为虚拟资源,可以映射到基础资源单元中。参考资源集合组中任意类型的资源块集合的长度、以及所包含的资源块的频域位置与基础资源单元在频域上对应。参考资源块集合组包括第一类型的资源块集合,或者包括第一类型的资源块集合和第二类型的资源块集合。第一类型的资源块集合和第二类型的资源块集合都包含L个资源块组,每一种类型的资源块集合都具备共同的特征。参考资源集合组中任意类型的资源块集合可以有一个或者一个以上。对于同一种类型的资源块集合中,L个资源块组中的各个资源块组中所包含的资源块数目可以不同。接入网设备可以根据终端设备的实际资源需求或空闲的资源块的频域位置,选择匹配的资源块集合。资源块组包括一个资源块,或者包括频域上相邻的至少两个资源块,所述L个资源块组中的各资源块组之间在频域上互不相邻。举例来说,定义一个基础资源单元的长度为10个资源块,参考资源集合组有3个A种类型的资源块集合。这3个A类型的资源块集合都包括2个资源块组可以是,第一个A类型的资源块集合中第一个资源块组包括2个资源块,第二个资源块组包括1个资源块;第二个A类型的资源块集合中第一个资源块组包括3个资源块,第二个资源块组包括2个资源块;第三个A类型的资源块集合中第一个资源块包括4个资源块,第二个资源块组包括3个资源块。
上述参考资源块集合组包括第一类型的资源块集合和第二类型的资源块集合,将不同类型的资源块集合分配用于2个或2个以上的终端设备,可以实现将M个基础资源单元中的不同资源块有效分配给2个或2个以上的终端设备,提高频谱利用率和小区覆盖范围。
2、接入网设备根据终端设备的资源请求为终端设备分配目标资源。
3、接入网设备确定与目标资源匹配的参考资源块集合组中的第二参考资源块集合,以及确定目标资源的频域位置和第二资源集合确定参考资源集合中每个资源块的频域位置的循环移位。
4、接入网设备将指示目标资源的第一指示信息发送给终端设备。
其中,第一指示信息指示与目标资源匹配的参考资源集合,以及和目标资源匹配的第二资源块集合中的资源块的循环移位值。
参阅图1,以下对本发明提供一种资源分配指示的方法进行举例说明,可知,在发送第一指示信息之前,终端设备发送资源请求至接入网设备,接入网设备为终端设备分配目标资源,然后接入网设备根据确定指示目标资源的第一指示信息的内容。所述方法包括:
101、接入网设备向终端设备发送第一指示信息;
其中,第一指示信息用于指示所述第二资源块集合中资源块的第二频域位置的信息。例如可以向终端设备指示将上述第二频域位置移位后的频域位置,即终端设备最终得到的第一资源块集合中资源块的第一频域位置。
可选的,第一指示信息满足以下之一:
a、第一指示信息用于指示所述第二资源块集合中资源块的第二频域位置和所述循环移位的移位值T,其中T为整数。
b、所述第一指示信息用于指示所述第一资源块集合中资源块的第一频域位置。例如,第一指示信息直接指示第一频域位置,无需指示第二资源块集合中资源块的第二频域位置、以及无需指示该第二频域位置进行循环移位后得到的第一资源块集合中第一频域位置的移位值。
第一指示信息可以通过上行调度授权信息发送给终端设备。
具体来说,上行调度授权信息通过物理下行控制信道(英文全称:Physical Downlink Control Channel,英文简称:PDCCH)或者增强物理下行控制信道(英文全称:Enhanced Physical Downlink Control Channel,英文简称:EPDCCH)发送给终端设备。
所述第一指示信息可以指示资源块集合组中的任意一个资源块集合为第二资源块集合,并指示用于根据该第二资源块集合中资源块的第二频域位置确 定第一资源块集合中资源块的第一频域位置。终端设备根据该第一资源块集合中资源块的第一频域位置在M个基础资源单元中确定目标资源。
或者,第一指示信息可以指示第一资源块集合中资源块的第一频域位置。终端设备根据该第一资源块集合中资源块的第一频域位置在M个基础资源单元中确定目标资源。
102、终端设备获取第一指示信息;
终端设备通过获取接入网设备发送的上行调度授权获取第一指示信息。
103、终端设备根据第一指示信息确定目标资源,并在目标资源上发送上行数据;
该目标资源包括M个基础资源单元中被分配给终端设备的资源块,该M个基础资源单元中每个基础资源单元中被分配的资源块位置与第一资源块集合中资源块的第一频域位置对应,第一资源块集合中资源块的第一频域位置为第二资源块集合中资源块的第二频域位置移位后的频域位置。可选的,该移位可以是循环移位的方式,具体不作限定。
104、接入网设备在第一指示信息所对应的目标资源上接收终端设备发送的上行数据;
接入网设备在为终端设备发送第一指示信息后,相应地,在和第一指示信息对应的目标资源上接收终端设备发送的上行数据。
以下分别对基础资源单元、目标资源、第一资源块集合、第二资源块集合以及第一指示信息的含义和相互之间的关系进行说明:
一、基础资源单元
免许可频谱资源上载波的
Figure PCTCN2016082095-appb-000015
个资源块被划分为N个基础资源单元,例如免许可频谱资源上载波的资源块的总个数
Figure PCTCN2016082095-appb-000016
为100,划分为10个基础资源单元,每个基础资源单元包括10个资源块。每个基础资源单元包括的资源块的数目也可以不同。例如免许可频谱资源上载波的资源块的总个数
Figure PCTCN2016082095-appb-000017
为75,划分为8个基础资源单元,其中7个基础资源单元各自所含的资源块个数为10,另外1个基础资源单元所含的资源块个数为5。接入网设备和终端设备对于免许可频谱资源上载波的资源块被划分为多少个基础资源单元,以及每个基础资源单元 中包括哪些资源块是预设相同的。
二、目标资源
接入网设备分配给终端设备发送数据的目标资源可以分布在M个基础资源单元中的每个基础资源单元中,M可以等于N,也可以小于N。即接入网设备分配给终端设备发送数据的资源可以分布在所有基础资源单元中的部分或者全部,本发明对此不作限制。
目标资源包括M个基础资源单元中被分配给所述终端设备的资源块,所述M个基础资源单元中每个基础资源单元中被分配的资源块位置与第一资源块集合中资源块的第一频域位置对应,所述第一资源块集合中资源块的第一频域位置为第二资源块集合中资源块的第二频域位置循环移位后的频域位置。
由于第一资源块集合中任意一个资源块的频域位置和M个资源块的频域位置对应,所述M个资源块分别为所述M个基础资源单元中每个基础资源单元中和所述任意一个资源块的频域位置相同的资源。即目标资源包括所述第一资源块集合中各个资源块的频域位置在M个基础资源单元中每个基础资源单元对应的资源块。第一资源块集合中的一个资源块和M个资源块对应,这M个资源块分别是M个基础资源单元中的资源块,这M个资源块在各自所述的基础资源单元中的相对位置相同,并且和第一资源块集合中所指的资源块的位置相同,具体可参考图2。
即目标资源包括所述第一资源块集合中各个资源块的频域位置对应的资源块,目标资源满足:与第一资源块集合中第k个资源块的频域位置fk对应的资源块为所述M个基础资源单元中的每个基础资源单元中频域位置为fk的资源块。实现在满足功率频谱密度的限制条件下,提高终端设备的发送功率。
例如,图2所示为目标资源和第一资源块集合之间的对应关系的一种可能实现方式的示意图。假设目标资源包括M=10个基础资源单元中被分配给所述终端设备的资源块,所述10个基础资源单元中每个基础资源单元中被分配的资源块位置与第一资源块集合中资源块的第一频域位置对应。这里假设第一资源块中资源块的第一频域位置为一个基础资源单元中的第2、7个资源块。那么目标资源为这10个基础资源单元中每个基础资源单元中的第2、7个资源块。而从目标资源所包括的资源块的频域排序来看,目标资源所包括的资源块即为 第2、7、12、17、22、27、32、37、42、47、52、57、62、67、72、77、82、87、92、97个资源块。
这样,目标资源包括所述M个基础资源单元中的每个基础资源单元中被分配给终端设备的资源块,在所述M个基础资源单元中,第三频域位置fk为第k个基础资源单元中被分配给所述终端设备的任一资源块的频域位置,与所述第三频域位置对应的第四频域位置fj为fk+K*(j-k),所述第四频域位置为第j个基础资源单元中被分配给所述终端设备的资源块的频域位置,其中,k、j和M均为正整数,M≥2,k≤j≤M。终端设备根据第一资源块集合中的一个资源块的位置确定出M个资源块的位置,而不需要接入网设备向终端设备指示M个基础资源单元中各个基础资源单元中被分配的资源块的位置,提高了接入网设备指示信息的效率。
或者,目标资源还可以满足:与第一资源块集合中第k个资源块的频域位置fk对应的资源块为M个资源块,所说M个资源块中的第m个资源块为所述M个基础资源单元中的第m个基础资源单元中频域位置为(fkm)mod K的资源块。其中,Δm是和第m个基础资源单元对应的资源映射参考值,这里1≤m≤M。Δm的取值是接入网设备和终端设备按照预设规则确定的第m个基础资源单元的“资源映射参考值”。上述M个基础资源单元中每个基础资源单元都有预设的、与之对应的“资源映射参考值”。K是一个基础资源单元中包括的资源块的个数。实现在满足功率频谱密度的限制条件下,提高终端设备的发送功率。
例如,假设目标资源包括M=10个基础资源单元中被分配给所述终端设备的资源块,所述10个基础资源单元中每个基础资源单元中被分配的资源块位置与第一资源块集合中资源块的第一频域位置对应。这里假设第一资源块中资源块的第一频域位置为一个基础资源单元中的第1、2、3、6、7个资源块。10个基础资源单元的Δm依次为0、1、3、6、5、3、7、0、2、5,那么目标资源为这10个基础资源单元中每个基础资源单元中的第2、7个资源块。而从目标资源所包括的资源块的频域增序来看,目标资源所包括的资源块即为这10各基础资源单元中的第1、2、3、6、7、12、13、14、17、18、24、25、26、29、30、32、33、37、38、39、41、42、46、47、48、54、55、56、59、60、63、64、68、69、70、71、72、73、76、77、83、84、85、88、89、91、92、96、 97、98个资源块。
三、第一资源块集合
第一资源块集合为一个基础资源单元中分配给终端设备的资源块的集合,M个基础资源单元中各基础资源单元中被分配的资源块可以参考第一资源块集合确定。具体来说,第一资源块集合满足以下之一:
a、所述第一资源块集合中第x个资源块的频域位置和M个资源块的频域位置对应,所述M个资源块分别为所述M个基础资源单元中每个基础资源单元中和所述第x个资源块的频域位置相同的资源块,其中,x正整数,1<x≤K,K为所述一个基础资源单元包括的资源块个数。
b、所述第一资源块集合中第k个资源块的频域位置和M个资源块的频域位置对应,所述第一资源块集合中第k个资源块的频域位置fk对应的第m个资源块为所述M个基础资源单元中的第m个基础资源单元中频域位置为(fkm)的资源块,其中,Δm为与第m个基础资源单元对应的资源映射参考值,k、m均为正整数,Δm为整数,1<k≤K,1<m≤K,K为所述一个基础资源单元包括的资源块个数。
可选的,在(fkm)>K时,所述第一资源块集合中第k个资源块的频域位置fk对应的资源块为所述第m个基础资源单元中的资源块为频域位置(fkm)在所述第M个基础资源单元中循环移位后的频域位置对应的资源块。
第一资源块集合中资源块的第一频域位置为第二资源块集合中资源块的第二频域位置循环移位后的频域位置。
具体的,所述第一资源块集合中第t个资源块的频域位置对应一个基础资源单元中的第U1个资源块,所述第二资源块集合中第t个资源块的频域位置对应所述第i个基础资源单元中的第U2个资源块,满足U1=mod(t1,K),U2=mod(U1+T,K),其中,T为所述循环移位的移位值,K为一个基础资源单元所包括的资源块的个数,t1、t2、U2、T为大于0的正整数。
例如,图3所示为第一资源块集合和第二资源块集合所包括的资源块的频域位置循环移位关系的示意图,如箭头“→”方向为按照频域增序方向循环移位的方向。假设第二资源块集合包括的资源块的第二频域位置为一个基础资源单元中的第1、2、6个资源块,以下分别以循环移位0、1、2、3、4和5位为例, 将第二资源块集合中资源块的第二频域位置循环移位后,得到的第一资源块集合中资源块的第一频域位置进行说明:
循环移位0位后得到:第一频域位置为一个基础资源单元中的第1、2、6个资源块;
循环移位1位后得到:第一频域位置为一个基础资源单元中的第2、3、7个资源块;
循环移位2位后得到:第一频域位置为一个基础资源单元中的第3、4、8个资源块;
循环移位3位后得到:第一频域位置为一个基础资源单元中的第4、5、9个资源块;
循环移位4位后得到:第一频域位置为一个基础资源单元中的第5、6、10个资源块;
循环移位5位后得到:第一频域位置为一个基础资源单元中的第1、6、7个资源块;
循环移位6位后得到:第一频域位置为一个基础资源单元中的第2、7、8个资源块;
循环移位7位后得到:第一频域位置为一个基础资源单元中的第3、8、9个资源块;
循环移位8位后得到:第一频域位置为一个基础资源单元中的第4、9、10个资源块;
即通过第二资源块集合中资源块的第二频域位置的不同循环移位,可以得到不同的第一资源块集合中资源块的第一频域位置。图3中所示为以第二资源块集合中资源块的第二频域位置循环移位0、1、4、5为例得到的第一资源块集合的第一频域位置。这里,循环移位的单位为一个资源块,且是按照一个基础资源单元中频域增序的方向做循环移位。循环移位0位或者n*K位的结果和不做循环移位相同。循环移位的移位值值Y为[0,K-1]中的整数,其中K为一个基础资源单元中包括的资源块的个数。
四、第二资源块集合
第二资源块集合为参考资源块集合组中的一个资源块集合。
接入网设备通过的第一指示信息将参考资源块集合中的一个资源块集合指示给终端设备。由此,终端设备可以获取到第二资源块集合中资源块的第二频域位置。终端设备由此第二资源块集合中资源块的第二频域位置和第一指示信息用于指示所述第二资源块集合中资源块的第二频域位置和第一指示信息所指示的循环移位的移位值可确定第一资源块集合中资源块的第一频域位置,终端设备进一步根据第一资源块集合中资源块的第一频域位置确定M个基础资源单元中每个基础资源单元中被分配的资源块位置并组成目标资源,并在目标资源上发送上行数据。
接入网设备通过第一指示信息指示第二资源块集合中资源块的第二频域位置,或者通过第一指示信息指示第一资源块集合中资源块的第一频域位置,即接入网设备只需要将指示一个基础资源单元中被分配的资源块的位置所对应的第二资源块集合中资源块的第二频域位置,或者将指示第一资源块集合中资源块的第一频域位置指示给终端设备即可,终端设备便可以根据预设的规则计算出每个基础资源单元中被分配的资源块的位置,这样,有效减少终端设备的计算步骤和提高确定资源位置的准确性,一定程度上减少终端设备的功耗。
可选的,接入网设备还可以根据第二资源块集合中资源块的个数O1来确定有效的移位值,从而确定是否需要在第一指示信息中携带移位值,具体为:
所述第二资源块集合中资源块的个数O1满足
Figure PCTCN2016082095-appb-000018
时,所述第二资源块集合对应的循环移位的移位值只有一种;
和/或,
所述第二资源块集合中资源块的个数O1为奇数时,所述第二资源块集合对应的循环移位的移位值只有一种;其中O1为正整数,K为一个基础资源单元包括的资源块个数。
五、参考资源块集合组
参考资源块集合组中至少包括一个资源块集合。参考资源块集合组中的资源块集合为接入网设备为中终端设备分配用于发送上行数据的目标资源所对应的第二资源块集合的备选资源块集合。
参考资源块集合组至少包括第一类型的资源块集合和第二类型的资源块集合类型。
1、第一类型的资源块集合满足以下特征:
(1)包括L个资源块组,所述资源块组包括一个资源块,或者包括频域上相邻的至少两个资源块,所述L个资源块组中的各资源块组之间在频域上互不相邻;
所述L个资源块组中的第V1个资源块组的第一个资源块的频域位置对应一个基础资源单元中第
Figure PCTCN2016082095-appb-000019
个资源块,其中1≤V1≤P1;
所述L个资源块组中的第V2个资源块组中的第一个资源块的频域位置对应一个基础资源单元中第
Figure PCTCN2016082095-appb-000020
个资源块,其中P1+1≤V2≤L;
这里“第一个资源块”指的是按照频域增序,在频域上的第一个资源块。
(2)按频域增序,所述L个资源块组中前P1个资源块组各自包括的资源块的个数均为M1,所述L个资源块组中后P2个资源块组各自包括的资源块的个数均为M2,其中,M1>M2,M1和M2均为正整数。
其中,L、P1、P2、V1、V2及K均为正整数,L≥2,P1≥1,P2=L-P1,K为所述一个基础资源单元包括的资源块个数。
L个资源块组中各自包括的资源块的个数尽量均匀化可以可以使终端设备发送的上行信息的峰均比值尽量低,提高终端设备发送功率的效率。
特别地,M3-M4=1时,L个资源块组中各自包括的资源块的个数差异最小,可以实现终端设备被允许发送的最大发送功率不受所包含的资源块个数较多的资源块组的限制。由于终端设备发送上行数据时,在每个资源块上的发送功率是均等的。如果L个资源块组各自包括的资源块的个数不同,终端设备被允许发送的最大上行功率受到所包含资源块个数最大的资源块组的限制。
举例来说,如果L=2,而两个资源块组中各自包括的资源块的个数分别是4个和2个,则会受到免许可频谱上最大发送功率谱密度的限制。例如免许可频谱上要求每MHz上的最大发送功率不超过10dBm。如果两个资源块组在位于不同的1MHz的带宽内,则第一个资源块组的4个资源块的最大发送功率为10dBm,而第二个资源块组的2个资源块的最大发送功率为10dBm,故从每个资源块上的发送功率来看,第一个资源块组中的资源块被允许发送的最大功率小于第一个资源块组中的资源块被允许发送的最大功率。为保证终端设备发送的每个资源块上的发送功率相同,终端设备的最大发送功率将被第一个资源块组中每个资源块上被允许发送的最大发送功率所限制。因此将L个资源块组中各资源块组包括的资源块个数应尽量相等。但是,如果L个资源块组中包括的资源块总个数不能被L整除,则可以是L个资源块组中前P1个资源块组各自包括的资源块的个数均为M1,所述L个资源块组中后P2个资源块组各自包括的资源块的个数均为M2,即L个资源块组中各资源块组包括的资源块个数尽量相等。
如图4,以一个基础资源单元包括10个资源块、L=2、P1=1,P2=1为例,第一类型的资源块集合中包括2个资源块组,在这2个资源块组中,第一个资源块组的第一个资源块为一个基础资源单元中的第1个资源块,第二个资源块组的第一个资源块为一个基础资源单元中的第7个资源块。按照频域增序,第一个资源块组包括M1个资源块,第二个资源块组包括M2个资源块,M1>M2。以M1-M2=1为例,参考资源块集合组中可以包括如图4中的(a)、b)以及(c)所示3个第一类型的资源块集合中任意一个或者任意组合。
图4中的(a)、(b)以及(c)所示的资源块集合各自的M1和M2取值依次为:M1=2,M2=1;M1=3,M2=2;和M1=4,M2=3。即图4中的(a)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、7个资源块;图4中的(b)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、7、8个资源块;图4中的(c)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、4、7、8、9个资源块。
可选地,在一些发明实施例中,若针对资源块集合选择任一移位值,可能会出现将L个资源块组分散的情况,例如图4中的(a)所示参考资源块集合, 如果将该资源块集合的第二频域位置(第1、2、7个资源块)循环移位9后,对应的频域位置为一个基础资源单元中的第1、6、10个资源块,形式上变为三个资源块组,即导致原资源块组分散。因此为实现将第一类型的资源块集合循环移位后,保证L个资源块组中的资源块不分散,同时保证资源块分配的均匀性,还可在使用上述第一类型的资源集合进行循环移位时,定义循环移位的移位值T满足:
T为集合[0,1,...l1]中的任一个,或者为集合[l2,l2+1,...l3]中的任一个,其中,
Figure PCTCN2016082095-appb-000021
。例如,上述图4中的(a)所示的资源块集合,所对应支持的移位值为集合[0,1,2,3]或者集合[4,5,6,7,8]中的一个值。上述图4中的(b)所示的资源块集合,所对应支持的移位值为集合[0,1,2]中的任一个值,或者为集合[4,5,6,7]中的任一个值。上述图4中的(c)所示的资源块集合,所对应支持的移位值为集合[0,1]或者为集合[4,5,6]中的任一个值。。
可选地,在本可选发明实施方式中,在接入网设备向终端设备指示第一指示信息时,由于可能对应第二资源块集合的可选移位值较多,若接入网设备将所有符合条件的移位值都计算出来,并指示给终端设备的话,不仅增加接入网设备对终端设备资源分配指示信息的负担,而且相应增加终端设备运算得到循环移位值的负担。可以通过以下手段来减少接入网设备和终端设备运算的功耗:
(1)、针对第一类型的第二资源块集合在移位值的可选集合中选择任一移位值。
即可减少接入网设备对终端设备资源分配指示信息的负担,并且相应的降低UE运算得到循环移位值的负担,即相应减少UE功耗,对UE的处理能力要求不高。例如,如图4中的(a)所示的资源块集合,如果所对应支持的移 位值为集合[0,1,2,3,4,5,6,7,8]中的任意一个值,则接入网设备需要将当前为终端设备的资源分配对应的移位值(即集合[0,1,2,3,4,5,6,7,8]中的哪一种移位值)指示给终端设备,即需要将资源分配所使用的9种移位值中的哪个移位值的信息指示给终端设备。
(2)缩小移位值的可选集合。
通过将该资源块集合所对应支持的移位值的可选集合缩小,实现降低接入网设备和终端设备的负担。例如上述图4中的(a)所示的资源块集合,可以只支持其中一种移位值,相应地,接入网设备可以在第一指示信息不需要区分当前为终端设备的资源分配对应的这些移位值中的哪一种。
再例如,上述图4中的(a)所示的资源块集合,可以只支持两种移位值。相应地,接入网设备可以在第一指示信息中只需要区分当前为终端设备的资源分配对应的这两种移位值中的哪一种,而不用区分当前为终端设备的资源分配对应的这两种以上移位值中的哪一种,这样可以降低接入网设备对终端设备资源分配指示信息的负担。优选的,对上述图4中的(a)所示的资源块集合,可以只支持移位值为0,或者只支持移位值为4。对上述图4中的(b)所示的资源块集合,可以只支持移位值为0,或者只支持移位值为4。对上述图4中的(c)所示的资源块集合,可以只支持移位值为0,或者只支持移位值为4。由于分配给终端设备的目标资源分布在M个基础资源单元中,故将移位值的可选集合缩小对于多个终端设备之间资源复用带来的频率选择性增益的影响很小。
2、第二类型的资源块集合满足以下特征(1)和(2),或者满足以下特征(3)和(4):
(1)第二类型的资源块集合包括L个资源块组,所述资源块组包括一个 资源块,或者包括频域上相邻的至少两个资源块,所述L个资源块组中的各资源块组之间在频域上互不相邻;
所述L个资源块组中的第V3个资源块组中的第一个资源块的频域位置对应一个基础资源单元中第
Figure PCTCN2016082095-appb-000022
个资源块,其中,1≤V3≤L;其中L≥1,K为所述一个基础资源单元包括的资源块个数。
这里“第一个资源块”指的是按照频域增序,在频域上的第一个资源块。
(2)按频域增序,所述L个资源块组中前P3个资源块组各自包括的资源块的个数均为M3,所述L个资源块组中后P4个资源块组各自包括的资源块的个数均为M4,其中,M3和M4均为正整数,L≥2,P3≥1,P4=L-P3,M3>M4
L个资源块组中各自包括的资源块的个数尽量均匀化可以可以使终端设备发送的上行信息的峰均比值尽量低,提高终端设备发送功率的效率。
特别地,M3-M4=1时,L个资源块组中各自包括的资源块的个数差异最小,可以实现终端设备被允许发送的最大发送功率不受所包含的资源块个数较多的资源块组的限制。由于终端设备发送上行数据时,在每个资源块上的发送功率是均等的。如果L个资源块组各自包括的资源块的个数不同,终端设备被允许发送的最大上行功率受到所包含资源块个数最大的资源块组的限制。
举例来说,如果L=2,而两个资源块组中各自包括的资源块的个数分别是4个和2个,则会受到免许可频谱上最大发送功率谱密度的限制,例如免许可频谱上要求每MHz上的最大发送功率不超过10dBm。如果两个资源块组在位于不同的1MHz的带宽内,则第一个资源块组的4个资源块的最大发送功率为10dBm,而第二个资源块组的2个资源块的最大发送功率为10dBm,故从每个资源块上的发送功率来看,第一个资源块组中的资源块被允许发送的最大功率小于第一个资源块组中的资源块被允许发送的最大功率。为保证终端设备发送的每个资源块上的发送功率相同,终端设备的最大发送功率将被第一个资源块组中每个资源块上被允许发送的最大发送功率所限制。因此将L个资源块组中各资源块组包括的资源块个数应尽量相等。但是,如果L个资源块组中包括的资源块总个数不能被L整除,则可以是L个资源块组中前P1个资源块组各 自包括的资源块的个数均为M1,所述L个资源块组中后P2个资源块组各自包括的资源块的个数均为M2,即L个资源块组中各资源块组包括的资源块个数尽量相等。
如图5,以一个基础资源单元包括10个资源块、L=2、P1=1,P2=1为例,第二类型的资源块集合中包括2个资源块组,在这2个资源块组中,第一个资源块组的第一个资源块为一个基础资源单元中的第1个资源块,第二个资源块组的第一个资源块为一个基础资源单元中的第6个资源块。按照频域增序,这2个资源块组中第一个资源块组包括M3个资源块,这2个资源块组中第二个资源块组包括M4个资源块,M3>M4。以M3-M4=1为例,参考资源块集合组中可以包括如图5中的(a)、(b)以及(c)所示3个第二类型的资源块集合中任意一个或者任意组合。图5中的(a)、(b)以及(c)所示的3个第二类型的资源块集合各自的M3和M4取值依次为:M3=2,M4=1;M3=3,M4=2;和M3=4,M4=3。
即图5中的(a)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、6个资源块;图5中的(b)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、6、7个资源块;图5中的(c)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、4、6、7、8个资源块。
可选地,第一资源块集合为第二类型的资源块集合时,所述移位值T为集合[0,1,...l1]中的任一个,或者为集合[l2,l2+1,...l3]中的任一个,其中,
Figure PCTCN2016082095-appb-000023
。如上述第1个第二类型的资源块集合,所对应支持的移位值为集合[0,1,2,3]或者集合[4,5,6,7,8]中的一个值;上述第2个第二类型的资源块集合,所对应支持的移位值为集合[0,1,2,3]或者集合[5,6,7]中的一个值;上述第3个第二类型的资源块集合,所对应支持的移位值为集合[0,1,2]或者集合[5,6]中的一个值。。
可选地,在本可选发明实施方式中,在接入网设备向终端设备指示第一指 示信息时,由于可能对应第二资源块集合的可选移位值较多,若接入网设备将所有符合条件的移位值都计算出来,并指示给终端设备的话,不仅增加接入网设备对终端设备资源分配指示信息的负担,而且相应增加终端设备运算得到循环移位的移位值的负担。具体减少接入网设备和终端设备运算的功耗的手段如下:
(1)针对第二类型的第二资源块集合在移位值的可选集合中选择任一移位值。
例如,如图5中的(a)所示的资源块集合,如果所对应支持的移位值为集合[0,1,2,3,4,5,6,7,8]中的任意一个值,则接入网设备需要将当前为终端设备的资源分配对应的移位值(即集合[0,1,2,3,4,5,6,7,8]中的哪一种移位值)指示给终端设备,即需要将资源分配所使用的9种移位值中的任一移位值的信息指示给终端设备。
(2)缩小移位值的可选集合。
通过将该资源块集合所对应支持的移位值的可选集合缩小,实现降低接入网设备和终端设备的负担。例如,如图5中的(a)所示的资源块集合,可以只支持其中一种移位值,相应地,接入网设备可以在第一指示信息不需要区分当前为终端设备的资源分配对应的这些移位值中的哪一种。
再例如,如图5中的(a)所示的资源块集合,可以只支持两种移位值。相应地,接入网设备可以在第一指示信息中只需要区分当前为终端设备的资源分配对应的这两种移位值中的哪一种,而不用区分当前为终端设备的资源分配对应的这两种以上移位值中的哪一种,这样可以降低接入网设备对终端设备资源分配指示信息的负担。优选的,对上述图5中的(a)所示的资源块集合, 可以只支持移位值为4,或者只支持移位值为8。对上述图5中的(b)所示的资源块集合,可以只支持移位值为3,或者只支持移位值为7。对上述图5中的(c)所示的资源块集合,可以只支持移位值为2,或者只支持移位值为6。由于分配给终端设备的目标资源分布在M个基础资源单元中,故将该移位值的可选集合缩小对于多个终端设备之间资源复用带来的频率选择性增益的影响很小。
另外,参考资源块集合组包括的第二类型的资源块集合类型的资源块集合满足的条件还可以是(3)和(4),具体如下:
(3)第二类型的资源块集合包括L个资源块组,所述资源块组包括一个资源块,或者包括频域上相邻的至少两个资源块,所述L个资源块组中的各资源块组之间在频域上互不相邻;
所述L个资源块组中的第V3个资源块组中的第一个资源块的频域位置对应一个基础资源单元中第
Figure PCTCN2016082095-appb-000024
个资源块,其中,1≤V3≤L;其中L≥2,K为所述一个基础资源单元包括的资源块个数。
这里“第一个资源块”指的是按照频域增序,在频域上的第一个资源块。
(4)所述L个资源块组中的各资源块组包括的资源块的个数均为M5,M5为正整数。
如图6,以一个基础资源单元包括10个资源块、L=2为例,第二类型的资源块集合中包括2个资源块组,这2个资源块组中第一个资源块组的第一个资源块为一个基础资源单元中的第1个资源块,这2个资源块组中第二个资源块组的第一个资源块为一个基础资源单元中的第6个资源块。这2个资源块组中每个资源块组都包括M5个资源块。取M5分别为2、4、6、8、10为例,参考资源块集合组中可以包括如图6中的(a)、(b)、(c)、(d)、(e)以及(f)所示6个第二类型的资源块集合中任意一个或者任意组合。
即图6中的(a)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、6个资源块;图6中的(b)所示的资源块集合中资源块的频域位 置为一个基础资源单元中的第1、2、6、7个资源块;图6中的(c)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、6、7、8个资源块;图6中的(d)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、4、6、7、8、9个资源块;图6中的(e)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1个资源块;图6中的(f)所示的资源块集合中资源块的频域位置为一个基础资源单元中的第1、2、3、4、5、6、7、8、9、10个资源块。
可选地,第一资源块集合为第二类型的资源块集合时,所述移位值T为集合[0,1,...l1]中的任一个,
Figure PCTCN2016082095-appb-000025
。如上述图6中的(a)所示的参考资源块集合,所对应支持的移位值为集合[0,1,2,3,4]中的一个值;如图6中的(b)所示的资源块集合,所对应支持的移位值为集合[0,1,2,3]中的一个值;如上述图6中的(c)所示的参考资源块集合,所对应支持的移位值为集合[0,1,2]中的一个值;如上述图6中的(d)所示的资源块集合,所对应支持的移位值为集合[0,1]中的一个值。
可选地,如上述图6中的(e)所示的资源块集合所对应支持的移位值为集合[0,1,2,3,4,5,6,7,8,9]中的一个值;上述图6中的(f)所示的资源块集合,所对应支持的移位值为0。
可选地,在一些发明实施方式中,第一资源块集合为第二类型的资源块集合时,例如为图6中的(a)所示的资源块集合,若针对资源块集合选择任一移位值,可能会带来接入网设备对终端设备资源分配指示信息的负担。如果所对应支持的移位值为集合[0,1,2]中的任意一个值,则接入网设备需要将当前为终端设备的资源分配对应的移位值(即集合[0,1,2]中的某个值)指示给终端设备,即需要将资源分配所使用的3种移位值中的哪个移位值的信息指示给终端设备。
如果将该资源块集合所对应支持的移位值的可选集合缩小,则将可以降低接入网设备对终端设备资源分配指示信息的负担。例如上述图5中的(a)所示的资源块集合,可以只支持其中一种移位值,相应地,接入网设备可以在第一指示信息中仅指示为终端设备分配的资源对应的第二资源块集合中资源块 的第二频域位置,而不需要指示对应的移位值,从而降低接入网设备和终端设备资源运算的负担。对上述图6中的(a)所示的资源块集合,可以只支持移位值为0、或者只支持移位值为1、或者只支持移位值为2。由于分配给终端设备的目标资源分布在M个基础资源单元中,故将该移位值的可选集合缩小对于多个终端设备之间资源复用带来的频率选择性增益的影响很小。
可选的,如果第二资源块集合中资源块的个数O1满足

时,该第二资源块集合对应的循环移位的移位值只有一种;
和/或,
如果第二资源块集合中资源块的个数O1为奇数时,该第二资源块集合对应的循环移位的移位值只有一种。
如果第二资源块集合中资源块的个数O1满足
Figure PCTCN2016082095-appb-000027
,那么在接入网设备使用第二资源块集合对应的资源分配方式为终端设备A分配上行资源时,接入网设备为另一个终端设备B分配的上行资源所使用的第二资源块集合中资源块的个数O2必然小于
Figure PCTCN2016082095-appb-000028
,该终端设备A和终端设备B在相同子帧通过频分复用方式共享上行资源。那么只要资源块的个数O2小于
Figure PCTCN2016082095-appb-000029
的第二资源块集合对应支持各种循环移位的移位值,则资源块的个数大于
Figure PCTCN2016082095-appb-000030
的第二资源块集合可以仅对应支持一种循环移位的移位值。
如果第二资源块集合中资源块的个数O1为奇数,该第二资源块集合可以仅对应支持一种循环移位的移位值。
可选的,第二资源块集合以及对应的循环移位的移位值之间的对应关系可以包括下表1中至少一行:
Figure PCTCN2016082095-appb-000031
Figure PCTCN2016082095-appb-000032
表1
可选地,在本可选发明实施方式中,接入网设备向终端设备指示第一指示信息,并根据第一指示信息确定目标资源,并在目标资源上发送上行数据。目标资源包括M个基础资源单元中被分配给终端设备的资源块,M个基础资源单元中每个基础资源单元中被分配的资源块位置与第一资源块集合中资源块的第一频域位置对应,第一资源块集合中资源块的第一频域位置为第二资源块集合中资源块的第二频域位置移位后的频域位置,其中M为正整数。
上述第二资源块集合、以及第二资源块集合对应的移位值满足以下至少一项:
对于所包括的资源块的数量大于4且小于8的第二资源块集合,对应的移位值只有一种;
对于所包括的资源块的数量小于5且为偶数的第二资源块集合,对应的移 位值大于一种;
对于所包括的资源块的数量小于8且为奇数的第二资源块集合,对应的移位值只有一种;
对于所包括的资源块的数量为3的第二资源块集合,对应的移位值有Ns种,1≤Ns<9;
对于所包括的资源块的数量为5的第二资源块集合,对应的移位值有Ns种,1≤Ns<7;
对于所包括的资源块的数量为6的第二资源块集合,对应的移位值有Ns种,1≤Ns<3;
对于所包括的资源块的数量为7的第二资源块集合,对应的移位值有Ns种,1≤Ns<5;
六、第一指示信息
第一指示信息的每一个指示值对应资源块集合组中的一个资源块集合,以及一个循环移位值。第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的映射关系如下表1所示。终端设备接收到第一指示信息后,可根据第一指示信息的指示值和该映射关系确定第二资源块集合以及相应的循环移位值,根据第二资源块集合和相应的循环移位值确定出第一资源块集合。根据第一资源块集合中资源块的第一频域位置可以对应确定M个基础资源单元中被分配的资源块来确定目标资源。
其中,上述映射关系如下表2:
Figure PCTCN2016082095-appb-000033
Figure PCTCN2016082095-appb-000034
表2
上表1中,资源块集合a~j为资源块集合组中所包括的资源块集合,资源块集合a~j中每一个资源块集合各自包括的资源块的第一频域位置各不相同。v1、v2、v3、v4、v5、v6、v7、v8、v9依次为资源块集合b~j各自为第二资源块集合时,所支持的循环移位值的个数。
可选地,对于资源块集合a~j中一个资源块集合,如果该资源块集合对应支持的移位值的个数只有一个,则第一指示信息中仅指示第二资源块集合中资源块的第二频域位置,而不用同时指示该资源块集合对应的移位值。需要说明的是,对于此种类型的第二资源块集合中资源块的第二频域位置所对应的移位值,由接入网设备和终端设备预定义,故不需要通过第一指示信息指示。
可选地,对于资源块集合a~j中一个资源块集合,如果该资源块集合对应支持的移位值的个数只有一个,则第一指示信息中可以为第二资源块集合中资源块的第二频域位置循环移位后的频域位置,即第一资源块集合中资源块的第一频域位置。
上述表1只是举例说明第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的对应关系。该映射关系的表可以根据资源块集合组中所包括的资源块集合的数目,以及其中各资源块集合所支持的循环移位的个数有所不同。接入网设备和终端设备均预先配置上述该映射关系。
按照本发明实施例中的参考资源块集合组中包括图4所示的3个第一类型的资源块集合、图5所示的3个第二类型的资源块集合和图6所示的6个第二类型的资源块集合为例,第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的对应关系如下表3所示。
Figure PCTCN2016082095-appb-000035
表3
表3中第二列中的{0}、{0 5}……等为索引号,如图5中的(a)所示的资源块集合中的“0”、“1”…“9”代表索引号,依次代表一个基础资源单元中的第一个资源块、第二个资源块…第十个资源块,可以理解的是,上述映射关系在接入网设备和终端设备侧都预先配置,实现接入网设备将分配的目标资源的位置指示给终端设备,使终端设备根据预设映射关系确定发送上行数据的目标资源,接入网设备在该目标资源上接收对应的终端设备发送的上行数据。
需要说明的是,第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的对应关系可以是表2中的部分行所指示的信息。例如,在第二资源块集合中资源块的第二频域位置(一个基础资源单元中的资源块索引)不包括7个时,第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的对应关系不包括表3中的以下两行:
54~58 {0 1 2 3 5 6 7} [0,1,2,5,6]中的第Iindex-54个值
59~63 {0 1 2 3 6 7 8} [0,1,4,5,6]中的第Iindex-59个值
对应地,这两行之后的其他行中Iindex的值都依次减去10,即如下表4所示:

再例如,第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的对应关系如表3所示。需要说明的是,第一指示信息的指示值Iindex和资源块集合组中每一个资源块集合,以及对应的循环移位值的对应关系可以是表5中的部分行所指示的信息。

可选地,第一指示信息的指示值对应第一资源块集合中资源块的第一频域位置的信息。第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为以下备选项中的一种:
如果第一资源块集合中资源块有1个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0}、{1}、{2}、{3}、{4}、{5}、{6}、{7}、{8}、{9}中的一种;

如果第一资源块集合中资源块有6个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0 1 2 5 6 7};或者,如果第一资源块集合中资源块有6个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{2 3 4 6 7 8};或者,如果第一资源块集合中资源块有6个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{3 4 5 7 8 9};
如果第一资源块集合中资源块有7个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0 1 2 3 6 7 8}、{2 3 4 5 7 8 9}中的一种;或者,如果第一资源块集合中资源块有7个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0 1 2 4 5 6 7}、{1 2 3 6 7 8 9}中的一种;
如果第一资源块集合中资源块有8个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0 1 2 3 5 6 7 8};或者,如果第一资源块集合中资源块有8个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{1 2 3 4 6 7 8 9};
如果第一资源块集合中资源块有9个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0 1 2 3 4 5 6 7 8};或者,如果第一资源块集合中资源块有9个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{1 2 3 4 5 6 7 8 9};
如果第一资源块集合中资源块有10个,则第一资源块集合中资源块的第一频域位置在一个基础资源单元中的资源块索引为{0 1 2 3 4 5 6 7 8 9}。

表6
可选的,在一些发明实施例中,接入网设备在给2个以上的终端设备分配资源时,可以将一个基础资源单元中的资源块分配给2个以上的终端设备,实现多个终端设备之间的频分复用以及提高资源的利用率,接入网设备可以指示至少一个终端设备的第二资源块集合为参考资源块集合组中第一类型的资源块集合,同时指示另外的至少一个终端设备的第二资源块集合为参考资源块集合组中第二类型的资源块集合,由此保证各个终端设备之间的资源块不重叠,最大限度的将整个基础资源单元中的资源块都分配给终端设备发送上行数据,达到多个终端设备资源上的频分复用的目的。接入网设备可以分别使用第一类型的资源块集合和第二类型的资源块集合将分配的资源块指示给2个以上的终端设备,将上行资源块分配给多个终端设备实现频分复用。以下以接入网设备已将一个基础资源单元中的第一资源块集合分配给第一终端设备,且将该基础资源单元中的其他资源块集合分配给第二终端设备为例:
以下以接入网设备将参考资源块集合组中的第一类型的资源块集合作为第二资源块集合指示给第一终端设备,并且将参考资源块集合组中如图5中的(c)所示的第二类型的资源块集合作为第二资源块集合指示给第二终端设备。
举例来说,假设接入网设备同时通过第一指示信息指示该第一终端设备和第二资源块集合对应的循环移位值为0。如图7所示,第一终端设备根据本实 施例所述方法可确定被分配的目标资源。在接入网设备为第一终端设备分配图示的目标资源(资源块0、1、2、3、5、6及7)后,除非接入网设备将参考资源块集合组中如图6中的(e)所示的第二类型的资源块集合作为第二资源块集合指示给第二终端设备,才能将M个基础资源单元中每个基础资源单元中的第9个资源块(如表2中的索引号8)分配给第二终端设备发送上行数据,否则M个基础资源单元中每个基础资源单元中的第9个资源块将无法分配给其他终端设备。故为将剩余的资源块分配给第二终端设备,接入网设备可以配合第一类型的资源块集合作为第二资源块集合指示给第以终端设备的前提下,将上述第二类型的资源块集合(例如图5中的(c)所示的资源块集合)作为第二资源块集合指示给第二终端设备。
又例如,接入网设备将如图4中的(a)所示的第二类型的资源块集合作为第二资源块集合指示给第二终端设备,接入网设备同时通过第一指示信息指示该第二终端设备和第二资源块集合对应的循环移位值为8。这样,第二终端设备根据本实施例所述方法可确定被分配的目标资源。上述M个基础资源单元中每个基础资源单元中的第9个资源块将有效分配给了除第二终端设备。接入网设备通过分别将参考资源块集合组中的不同类型的资源块集合指示给不同的终端设备,可以达到多个终端设备资源上的有效频分复用的效果。
以上对本发明中一种资源分配指示的方法进行说明,以下对执行上述资源分配指示的方法的接入网设备和终端设备进行描述,在设备侧,关于参考资源集合组、基础资源单元、目标资源、第一资源块集合、第二资源块集合以及第一指示信息的意义和相互之间的关系可参考本发明实施例中的方法实施例中的描述,此处不作赘述。
一、参照图7,对终端设备70进行说明,终端设备70包括:
接收模块701,用于获取第一指示信息;
