Description

一种资源配置方法、装置、设备和计算机可读存储介质 技术领域
本发明实施例涉及移动通信技术领域,尤其涉及一种资源配置方法、装置、设备和计算机可读存储介质。
背景技术
随着无线通信技术的发展和用户对通信需求的日益增加,同时,为了满足更高、更快和更新的通信需要,第五代移动通信(5th Generation,简称为5G)技术已成为未来网络发展的趋势。
5G通信***被认为是在更高频带(例如3GHz以上)中实施,以便完成更高的数据速率。高频通信的特点在于具有比较严重的路损、穿透损耗,在空间传播与大气关系密切。由于高频信号的波长极短,可以应用大量小型天线阵,以使得波束成形技术能够获得更为精确的波束方向,以窄波束技术的优势提高高频信号的覆盖能力,弥补传输损耗,是高频通信的一大特点。
传统的长期演进(Long Term Evolution,简称为LTE)***中,物理下行控制信道(Physical Downlink Control Channel,简称为PDCCH)主要用于指示数据信道传输的下行以及上行授权信息。在LTE***中,终端需要在每个子帧中都盲检测并尝试接收PDCCH;并且,由于PDCCH的设计是按照全***带宽进行分布式(distributed)映射的,因此终端每次尝试接收PDCCH都需要在全带宽上进行盲检测。有研究表明,由于终端的盲检测带来的耗电占用终端总耗电的30%左右。在5G通信***中,***带宽往往会更宽,最宽可能达到LTE***带宽的几倍到几十倍,为了降低终端盲检测的复杂度,在3GPP的讨论中提出了控制资源集(control resource set)的概 念,一个控制资源集由频域上的一个或多个物理资源块组成,一个控制资源集又被称为一个子带。一个终端仅允许在一个或多个控制资源集上接收PDCCH,这可以在一定程度上降低终端由于盲检测PDCCH所带来的耗电。然而,由于5G通信***中的调度时间单元往往变得更小,通常以微秒us为级别,因此相比于LTE***来说,终端的盲检测复杂度以及由于盲检测PDCCH所带来的耗电问题将非常严重。

本发明实施例中,网络侧配置一套或多套控制资源集,其中当配置多套控制资源集时,多套控制资源集分别对应一套时域资源。所述每一套控制资源集中包含一个或多个控制资源集。终端在每套时域资源上仅在对应的控制资源集上尝试接收控制信道。控制资源集(control resource set)又称为控制子带(control subband),每个控制子带由频域上一个或多个连续或非连续的PRB组成,在时域上由一个或多个符号组成。可选地,每个控制子带由频域上一个或多个连续的PRB组成。可选地,一个终端的多套控制资源集在时域上所占用的符号数目可以是独立配置的。可选地,每套控制资源集中的多个控制资源集在时域上所占用的符号数目也可以是独立配置的。通常,每套资源集或每个资源集在时域上所占用的符号数目指在一个调度时间单元内控制资源集所占用的符号数目;可选地所占用的符号数目小于调度时间单元中包含的总的符号数目且不超过预定数目,可选地这预定数目个符号为一个调度时间单元中从第一个符号开始的连续的预定数目个符号。所述控制资源集主要用于终端通过盲检测尝试接收控制信息,为终端进行尝试接收控制信息的时频资源区域,但可选地若所述控制资源集中存在空闲资源(没有发送任何控制信息),则可以通过配置的方式决定这些空闲资源是否用于其它信号/信道的传输,例如用于数据信道的传输。可选地,多个控制资源集之间在频域上可以重叠或部分重叠。多套控制资源集分别具有独立的时域资源,基站为每套控制资源集配置独立的时域资源,多套控制资源各自的时域资源可以相同或不同。作为一个可选实施例,每套控制资源集对应的时域资源指一个或多个调度时间单元的集合,这些调度时间单元中包含该套控制资源集或者包含该套控制资源资源中的至少一个控制资源集。其中调度时间单元由一个或多个时间单元组成,可选地, 时间单元为时隙、微时隙、符号、子帧或者帧。其中,每一套控制资源集所对应的时域资源也是由网络侧配置给终端的。进一步可选地,每套控制资源集中的多个控制资源集也可以分别对应一套时域资源,可选地,每套控制资源集中的每个控制资源集对应的时域资源为该套控制资源集所对应的时域资源的子集。
可选地,当为终端配置多套控制资源集时,所述多套控制资源集中任意一套控制资源集对应的频域资源包含或被包含在任意另一套控制资源集对应的频域资源中。例如配置两套控制资源集,则一套资源集(即控制资源集)所对应的频域资源为另一套资源集所对应的频域资源的子集,即一套资源集对应的频域资源较大,另一套资源集对应的频域资源较小。终端分别在不同的时域资源上对两套资源集分别盲检测控制信道。
进一步地,本发明实施例方法还包括网络侧为终端配置所述一套或多套控制资源集中至少一套控制资源集中的多个控制资源集的优先级属性。按照该优先级属性,基站选择优先级最高的可用的控制资源集发送控制信道/控制信息,终端按照控制资源集的优先级属性从高到低依次尝试接收控制信道/控制信息,直到找到目标控制信道/控制信息为止。
可选地,所述控制资源集的优先级属性包括所述多个控制资源集之间的优先级顺序、所述控制资源集对应的多个搜索空间之间的优先级顺序、所述控制资源集对应的搜索空间的多个聚合级别之间的优先级顺序、所述控制资源集对应的搜索空间的多个候选控制信道之间的优先级顺序中至少之一。作为本发明一个可选实施例,终端确定多个控制资源集之间的优先级顺序,按照优先级从高到低的顺序依次在对应的控制资源集上尝试接收控制信道,若接收到预定数目的控制信道则停止在剩余的控制资源集上尝试接收。作为本发明的又一个可选实施例,终端确定所述控制资源集对应的多个搜索空间之间的优先级顺序,按照优先级从高到低的顺序依次在所 述控制资源集对应的多个搜索空间上尝试接收控制信道,若接收到预定数目的控制信道则停止在剩余的搜索空间上尝试接收。作为本发明的又一个实施例,终端确定所述控制资源集对应的搜索空间的多个聚合级别之间的优先级顺序,按照优先级从高到低的顺序依次在所述控制资源集中多个聚合级别下的搜索空间上尝试接收控制信道,若接收到预定数目的控制信道则停止对剩余的聚合级别的尝试接收。作为本发明的又一个实施例,终端确定所述控制资源集对应的搜索空间的多个候选控制信道之间的优先级顺序,按照优先级从高到低的顺序依次对所述控制资源集中多个候选控制信道尝试接收,若接收到预定数目的控制信道则挺尸对剩余的候选控制信道的尝试接收。可选地,这里的预定数目通常为固定的有限数目的控制信道,该数目为基站通给给终端,或者为基站和终端预先约定的。该数目可以理解为终端在当前调度时间单元内能接收到的最大数目的控制信道。例如假设当前调度时间单元内不支持公共控制信道的传输,则终端只需要盲检测终端专有的控制信道即可,这时该预定数目为一个;假设当前调度时间单元内支持公共控制信道的传输,该预定数目为两个。
可选地,在所述具有优先级属性的控制资源集中,优先级高的控制资源集中传输的控制信息用于指示优先级低的控制资源集中的控制信息的传输情况,包括指示优先级低的控制资源集中是否有控制信息、控制信息在所述优先级低的控制资源集中的时域和/或频域位置。可选地,这里的控制信息均指终端专有的控制信息。可选地,终端从优先级高的控制资源集中获取优先级低的控制资源集中的控制信息的传输情况:若优先级高的控制资源集中指示优先级低的控制资源集中没有对应的控制信道,将优先级低的控制资源集中尝试接收控制信道;或者根据优先级高的控制资源集中的控制信息指示的时频资源位置在优先级低的控制资源集中尝试接收控制信道。
可选地,所述优先级最高的控制资源集中承载公共控制信息。其中所述公共控制信息向终端指示调度时间单元的时间结构、调度时间单元对应的长度、调度时间单元聚合情况下的聚合级别、所述控制资源集中空闲的控制资源集。可选地,这里的调度时间单元的时间结构,指所述调度时间单元中包含的符号是上行、下行或者保留;所述调度时间单元对应的长度,指所述调度时间单元中包含的符号的个数;所述调度时间单元聚合情况下的聚合级别,指一个聚合的调度时间单元中所包含的调度时间单元的个数;所述控制资源集中空闲的控制资源集,指未被(任何终端)使用的控制资源集,其中可选地该未被使用的控制资源集可用于数据信道的传输。可选地,终端在优先级最高的控制资源集中尝试接收公共控制信息。
所述控制资源集的优先级属性可以通过信令指示给终端,例如可以通过终端专有的高层信令通知给终端。或者通过其它的参数或配置间接地、隐含地指示给终端,例如:所述多个控制资源集之间的优先级顺序和所述多个控制资源集在频域上的顺序存在对应关系,终端根据所述多个控制资源集在频域上的顺序确定所述多个控制资源集之间的优先级顺序;或者,所述控制资源集对应的多个搜索空间之间的优先级顺序和所述多个搜索空间在频域上的顺序存在对应关系,终端根据所述多个搜索空间在频域上的顺序确定所述控制资源集对应的多个搜索空间之间的优先级顺序;或者,所述控制资源集对应的搜索空间的多个聚合级别之间的优先级顺序和所述多个聚合级别的大小顺序之间存在对应关系,终端根据所述多个聚合级别的大小顺序确定所述控制资源集对应的搜索空间的多个聚合级别之间的优先级顺序;或者,所述控制资源集对应的搜索空间的多个候选控制信道之间的优先级顺序和所述多个候选控制信道在频域上的顺序或者所述多个候选控制信道对应的聚合级别大小顺序之间存在对应关系,终端根据所述多个候选控制信道在频域上的顺序或者所述多个候选控制信道对应的聚合级 别大小顺序确定所述控制资源集对应的搜索空间的多个候选控制信道之间的优先级顺序。
进一步地,本发明实施例方法还包括网络侧为终端配置所述一套或多套控制资源集中至少一套控制资源集的搜索空间属性。可选地,这里的搜索空间为供终端要进行盲检测的一组候选控制信道的集合。候选控制信道由一个或多个CCE组成,组成候选控制信道的CCE的个数称之为所述候选控制信道的聚合级别。终端根据所述搜索空间属性确定每个控制资源集上的候选控制信道,并在每个控制资源集上仅尝试接收对应的候选控制信道。可选地,终端根据所述搜索空间属性确定每个控制资源集上的候选控制信道或者子搜索空间,这里的子搜索空间为搜索空间的子集,子搜索空间也是由一个或多个候选控制信道组成。可选地,可以预先约定几种搜索空间属性,并通过高层信令给终端的每个控制资源集配置其中一种搜索空间属性。
可选地,所述控制资源集的搜索空间属性包括所述搜索空间在每个控制资源集上的聚合级别、所述搜索空间在每个控制资源集所占用的符号或符号子集上的聚合级别、所述搜索空间在每个控制资源集上的控制信息负载大小、所述搜索空间在每个控制资源集所占用的符号或符号子集上的控制信息负载大小、所述搜索空间在每个控制资源集上每个聚合级别所包含的候选控制信道、所述搜索空间在每个控制资源集所占用的符号或符号子集上每个聚合级别所包含的候选控制信道、所述搜索空间在每个控制资源集上的候选控制信道的传输类型、所述搜索空间在每个控制资源集上、所占用的符号或符号子集上的控制信息负载大小、所述搜索空间在每个控制资源集上的候选控制信道的类型、所述搜索空间在每个控制资源集上、所占用的符号或符号子集上的候选控制信道的类型、所述搜索空间在每个控制资源集上的控制信息的级别、所述搜索空间在每个控制资源集所占用的 符号或符号子集上的控制信息的级别、所述搜索空间在每个控制资源集上的传输业务类型、所述搜索空间在每个控制资源集上所占用的符号或符号子集上的传输业务类型中至少之一。进一步可选地,这里的控制信息负载大小为控制信道中承载的有效控制信息的负载;控制信道的传输类型主要包括集中式(localized)和分布式(distributed)两种,其中集中式传输是指候选控制信道映射的时域和/或频域资源是聚集在一起的,分布式传输是指候选控制信道映射的时域和/或频域资源是离散的;候选控制信道的类型,主要包括公共控制信道或者终端专有的控制信道两种类型;所述控制信息的级别,即单级控制信息或多级控制信息,控制信息的级别值该终端需要盲检测的控制信息为单级控制信息或者多级控制信息。作为一个可选实施例,控制信息包括两个级别,其中第一个级别为单级控制信息或者两级控制信息的第一级控制信息,第二个级别为两级控制信息中的第二级控制信息,第一级控制信息和第二级控制信息分别用于指示数据信道的部分或全部传输参数信息,可选地,第一级控制信息还用于指示第二级控制信息的传输参数信息。这里的传输参数信息包括时频资源信息、参考信号资源信息、传输方案信息、调制等级信息、编码等级信息等至少之一;所述传输业务类型,主要包括低时延高可靠通信(URLLC)、增强型移动宽带(eMBB)或者大连接物联网(mMTC)等业务。
进一步地,本发明实施例方法还包括网络侧为终端配置所述每套控制资源集的以下一项或多项属性:所述每个控制资源集在时域上占用的符号数、所述每个控制资源集REG到CCE的映射规则、所述每个控制资源集控制信道单元CCE到候选控制信道的映射规则、所述每个控制资源集的DMRS图样、所述每个控制资源集的解调参考信号DMRS密度、所述每个控制资源集上的捆绑的REG的数目(即REG bundling size)。可选地,终端利用上述属性,接收控制信息/控制信道,有利于终端对控制信息/控制信道 的快速接收。
需要说明的是,本发明实施例中所描述的“控制信息”也可以用“控制信道”或者“候选控制信道”来代替。本文中所描述的“预定数目”可以是基站和终端预先约定好的,或者由基站指示给终端。本文中所描述的“配置”如无特别说明,均可以通过以下方式至少之一实现:基站和终端预先约定的方式;基站通过终端专有的高层信令指示给终端;基站通过公有控制信息通知给终端;基站通过终端专有(UE-specific)控制信息通知给终端。
下面结合具体场景实施例对本发明进行详细描述。
实施例1
本实施例对应多套控制资源集,每套控制资源集对应不同的时域资源。
如图8所示,基站为终端配置了两套控制资源集,分别对应两套不同的时域资源。假设一个子帧中包含16个时隙,在每个子帧中的时隙{5,10,15}对应的控制资源集为第二套控制资源集,每个子帧中的剩余时隙对应的控制资源集为第一套控制资源集。
终端在每个子帧的时隙5、10和15中,在第二套控制资源集对应的搜索空间上尝试接收目标控制信道,在每个子帧的剩余时隙中,在第一套控制资源集对应的搜索空间上尝试接收目标控制信道。
其中,每一套控制资源集所对应的时域资源由网络侧通过终端专有的高层信令或者共有控制信令指示给终端。
需要说明的是,当基站为终端仅配置了一套控制资源集,该控制资源集的时域资源可以是配置的,也可以是基站和终端预先约定好的时域资源,例如:默认该时域资源为每个调度时间单元(时隙)。每一套控制资源集中的多个控制资源集之间也可以分别占用不同的时域资源,这时多个控制资源集所对应的时域资源也可以由网络侧配置给终端。
实施例2
本实施例为控制资源集配置优先级。
如图9所示,基站为终端配置了两个控制资源集,其中每个控制资源集由多个连续的PRB组成。基站为这两个控制资源集定义优先级,比如第二个控制资源集(控制资源集1)的优先级最高,第一个控制资源集(控制资源集0)的优先级次之,并且基站将该优先级信息指示给终端。
终端获得这两个控制资源集的配置信息以及优先级信息之后,将先在优先级最高的控制资源集(即控制资源集1)上尝试接收目标控制信道,当在该控制资源集上成功接收到了目标控制信道,则不再在另一个控制资源集上再进行尝试接收,否则继续在另一个控制资源集上尝试接收目标控制信道。
作为本发明实施例的又一种实施方式,也可以通过其它参数或配置间接获取多个控制资源集之间的优先级信息。例如:所述多个控制资源集之间的优先级顺序和所述多个控制资源集在频域上的顺序存在对应关系,终端根据所述多个控制资源集在频域上的顺序确定所述多个控制资源集之间的优先级顺序;或者,
所述控制资源集对应的多个搜索空间之间的优先级顺序和所述多个搜索空间在频域上的顺序存在对应关系,终端根据所述多个搜索空间在频域上的顺序确定所述控制资源集对应的多个搜索空间之间的优先级顺序;或者,
所述控制资源集对应的搜索空间的多个聚合级别之间的优先级顺序和所述多个聚合级别的大小顺序之间存在对应关系,终端根据所述多个聚合级别的大小顺序确定所述控制资源集对应的搜索空间的多个聚合级别之间的优先级顺序;或者,
所述控制资源集对应的搜索空间的多个候选控制信道之间的优先级顺 序和所述多个候选控制信道在频域上的顺序或者所述多个候选控制信道对应的聚合级别大小顺序之间存在对应关系,终端根据所述多个候选控制信道在频域上的顺序或者所述多个候选控制信道对应的聚合级别大小顺序确定所述控制资源集对应的搜索空间的多个候选控制信道之间的优先级顺序。
可选的,例如越靠近中心频率(相对于终端的带宽或***的带宽能力)的控制资源集的优先级越高,或者按照频域资源的频率从高到低、或从低到高的顺序定义不同控制资源集之间的优先级。在终端接入***之后,不同的终端可以具有不同的优先级指示。
作为本发明实施例的又一种实施方式,可以通过优先级高的控制资源集上接收到的控制信息指示优先级低的控制资源集上是否还有目标控制信道。若指示有,则终端将继续在优先级低的控制资源集上尝试接收目标控制信道;若指示无,则终端将不会在优先级低的控制资源集上再次尝试接收操作。
作为本发明实施例的又一种实施方式,基站只在终端的优先级最高的控制资源上发送公共控制信道,终端只需要在优先级最高的控制资源上尝试接收公共控制信道。
实施例3
本实施例为各个控制资源集分配搜索空间。
假设每个控制资源集上的搜索空间的定义是统一的,如图10所示,每个控制资源集的搜索空间共有{1,2,4,8}四种聚合级别(Aggregation Level,简称为AL)。聚合级别为N的子搜索空间的每个候选控制信道由N个CCE组成。为了方便下面的描述,对每个聚合级别下的候选控制信道分别进行了索引,例如聚合级别为8的候选控制信道只有1个,索引为0;聚合级别为4的候选控制信道有2个,索引分别为0和1;依次类推。
当基站为终端配置多个控制资源集时,终端的搜索空间将分配在多个控制资源集上。
作为本发明实施例的一种实施方式,基站在为终端配置控制资源集的同时还向终端配置每个控制资源集对应的聚合级别。如表格1所示,控制资源集0上对应的搜索空间的聚合级别为{4,8}中的至少一个,控制资源集1上对应的搜索空间的聚合级别为{1,2}中的至少一个。终端将在控制资源集0上仅尝试接收聚合级别为4或8的候选控制信道,在控制资源集1上仅尝试接收聚合级别为1或2的候选控制信道。
表格1
控制资源集索引 聚合级别
0 {4,8}

作为本发明的又一种实施方式,基站在对终端配置控制资源集的同时向终端配置每个控制资源集的每个聚合级别下的候选控制信道。如图11A所示为配置给控制资源集0上的候选控制信道,如图所示控制资源集0上聚合级别为8包括了1个候选控制信道,即为图10中索引为0的候选控制信道,聚合级别为4的候选控制信道也只有1个,即为图10中索引为0的候选控制信道,聚合级别为2的候选控制信道包括2个,即为图10中索引为0和2的候选控制信道,聚合级别为1的候选控制信道包括5个,即为图10中索引为0、2、3、6和7的候选控制信道。如图11B为配置给控制资源集1上的候选控制信道,如图所示控制资源集1上聚合级别为8包括了1个候选控制信道,即为图10中索引为0的候选控制信道,聚合级别为4包括了1个候选控制信道,即为图10中索引为1的候选控制信道,聚合级别为2包括了2个候选控制信道,即为图10中索引为1和3的候选控制信道,聚合级别为1包括了5个候选控制信道,即为图10中索引为0、1、4、5和7的候选控制信道。值得说明的是,多个控制资源集上的搜索空间 的候选控制信道的配置可以是基站通过信令指示给终端,也可以由基站和终端预先约定的,也可以是由基站和终端预先约定几种预定的划分方式,然后再由基站选择其中一种并将该选择结果通过信令通知给终端。终端在控制资源集0上仅尝试接收如图11A所示的候选控制信道,在控制资源集1上仅尝试接收如图11B所示的候选控制信道。可选地,两个控制资源集上的总的候选控制信道的数目不超过某个预定数目。这个预定数目可以是基站和终端预先约定好的,或者由基站指示给终端。
作为本发明的实施例的又一种实现方式,基站在对终端配置控制资源集的同时向终端配置每个控制资源集上的候选控制信道所承载的有效控制信息的大小。假设有效控制信息大小共有{20,40,60,80}比特四种选择,如表格2所示,控制资源集0上对应的候选控制信道所承载的有效控制信息的大小的可选范围为{20,40}比特,控制资源集1上对应的候选控制信道所承载的有效控制信息的大小的可选范围为{60,80}比特。终端将在控制资源集0上仅尝试接收承载的有效控制信息大小为20比特或者40比特的候选控制信道,在控制资源集1上仅尝试接收承载的有效控制信息大小为60比特或者80比特的候选控制信道。

实施例4
本实施例为搜索空间在一个控制资源集的不同符号子集上的分配。
假设每个控制资源集中每个符号子集上的搜索空间的定义是统一的,如图10所示,每个控制资源集中每个符号子集上的搜索空间共有{1,2,4,8}四种AL。聚合级别为N的子搜索空间的每个候选控制信道由N个CCE组成。为了方便下面的描述,对每个聚合级别下的候选控制信道分别进行了 索引,例如聚合级别为8的候选控制信道只有1个,索引为0;聚合级别为4的候选控制信道有2个,索引分别为0和1;依次类推。
当基站为终端配置一个控制资源集但包含多个符号子集时,终端的搜索空间将分配在该控制资源集的多个符号子集上。其中控制资源集的一个符号子集包含该控制资源集的一个或多个符号。符号子集也是由基站配置给终端的。如图12所示一个控制资源集包含的符号数为3个,其中第1个符号(OS0)为该控制资源集的一个符号子集(符号子集0),剩余2个符号(OS1和OS2)为该控制资源集的另一个符号子集(符号子集1)。这里的OS指OFDM符号(OFDM symbol,简称为OS)。符号子集也可以是基站和终端预先约定好的,例如约定控制资源集的每个符号分别为一个符号子集,或者约定控制资源集的所有符号即为一个符号子集。
作为本发明实施例的一种实施方式,基站在对终端配置控制资源集和符号子集的同时还向终端配置该控制资源集中每个符号子集上对应的聚合级别。如表格3所示,符号子集0上对应的搜索空间的聚合级别为{4,8}中的至少一个,符号子集1上对应的搜索空间的聚合级别为{1,2}中的至少一个。终端将在符号子集0上仅尝试接收聚合级别为4或8的候选控制信道,在符号子集1上仅尝试接收聚合级别为1或2的候选控制信道。

作为本发明的又一种实施方式,基站在对终端配置控制资源集及其符号子集的同时向终端配置该控制资源集每个符号子集下的每个聚合级别下的候选控制信道。如图11A所示为配置给符号子集0上的候选控制信道,如图所示符号子集0上聚合级别为8包括了1个候选控制信道,即为图10中索引为0的候选控制信道,聚合级别为4的候选控制信道也只有1个, 即为图10中索引为0的候选控制信道,聚合级别为2的候选控制信道包括2个,即为图10中索引为0和2的候选控制信道,聚合级别为1的候选控制信道包括5个,即为图10中索引为0、2、3、6和7的候选控制信道。如图11B为配置给符号子集1上的候选控制信道,如图所示控制资源集1上聚合级别为8包括了1个候选控制信道,即为图10中索引为0的候选控制信道,聚合级别为4包括了1个候选控制信道,即为图10中索引为1的候选控制信道,聚合级别为2包括了2个候选控制信道,即为图10中索引为1和3的候选控制信道,聚合级别为1包括了5个候选控制信道,即为图10中索引为0、1、4、5和7的候选控制信道。值得说明的是,多个符号子集上的搜索空间的候选控制信道的配置可以是基站通过信令指示给终端,也可以由基站和终端预先约定的,也可以是由基站和终端预先约定几种预定的划分方式,然后再由基站选择其中一种并将该选择结果通过信令通知给终端。终端在符号子集0上仅尝试接收如图11A所示的候选控制信道,在符号子集1上仅尝试接收如图11B所示的候选控制信道。可选地,两个符号子集上的总的候选控制信道的数目不超过某个预定数目。这个预定数目可以是基站和终端预先约定好的,或者由基站指示给终端。
作为本发明的实施例的又一种实现方式,基站在对终端配置控制资源集及其符号子集的同时向终端配置该控制资源集每个符号子集上的候选控制信道所承载的有效控制信息的大小。假设有效控制信息大小共有{20,40,60,80}比特四种选择,如表格4所示,符号子集0上对应的候选控制信道所承载的有效控制信息的大小的可选范围为{20,40}比特,符号子集1上对应的候选控制信道所承载的有效控制信息的大小的可选范围为{60,80}比特。终端将在符号子集0上仅尝试接收承载的有效控制信息大小为20比特或者40比特的候选控制信道,在符号子集1上仅尝试接收承载的有效控制信息大小为60比特或者80比特的候选控制信道。
