本申请主张在2018年2月11日在中国提交的中国专利申请号No.201810142644.2的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别涉及一种搜索空间的监听信息的确定方法及装置。
背景技术
长期演进(Long Term Evolution,LTE)系统中,用户设备(User Equipment,UE,也称终端)只监听一个物理下行控制信道(Physical Downlink Control CHannel,PDCCH)信道。在该PDCCH内,UE盲检固定的搜索空间内的PDCCH候选,且盲检PDCCH候选的总数是确定的。
5G NR系统支持为UE配置多个控制资源集(control resource set,CORESET)以及多个搜索空间(Search space),并为每个搜索空间灵活配置盲检数目,CORESET与搜索空间之间可以灵活关联,另一方面,为了降低UE的实现复杂度,NR系统规定了UE在单位时间内的最大盲检数以及最大信道估计数,即所有搜索空间上的盲检总数之和以及信道估计之后不能超过该上限。
由于搜索空间有独立的监听周期,如果按照UE支持的最大的盲检数或信道估计数在所有配置的CORESET上分配盲检数量或信道估计数量,则可能会导致在某些时间点,系统只能使用远小于UE支持的最大盲检数或信道估计数。以盲检数为例,假设UE最大的盲检数为44,分配了两个搜索空间SS-1,以及SS-2。SS-1周期为2时隙,SS-2的周期为4时隙。如果SS-1分配的盲检总数为24,SS-2的盲检总数为20,那么在第0、4、8、……、时隙,UE同时盲检SS-1与SS-2,且盲检总数不超过支持的最大盲检数(44)。但在第2、6、10、……、时隙,UE只盲检SS-1,且盲检的总数只有24。
可以看出,这种分配方式不能充分利用UE的能力,大大降低了系统的控制资源利用率,提高了控制信道分配阻塞概率。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开进行详细描述。
本公开针对相关技术中的盲检数量或信道估计数量的分配方式,不能充分利用终端的能力,会存在大大降低系统的控制资源利用率,提高控制信道分配阻塞概率的问题,提供一种搜索空间的监听信息的确定方法及装置。
具体地,如图1所示,图1为本公开实施例的搜索空间的监听信息的确定方法的流程示意图,所述搜索空间的监听信息的确定方法,包括:
步骤101,当终端监听至少两个搜索空间、且所述至少两个搜索空间的监听信息的初始个数之和大于所述终端支持的监听信息总数时,确定所述至 少两个搜索空间中每个搜索空间的监听信息的第一个数;
其中,所述至少两个搜索空间中每个搜索空间的监听信息的第一个数之和小于或等于监听信息总数;
需要说明的是,该至少两个搜索空间指的是终端在任一单位时间内同时监听的搜索空间。
具体地,该监听信息总数为终端支持的监听信息的最大个数;网络为终端分配一个或多个搜索空间,并配置每个搜索空间的监听信息的初始个数,且该初始个数不超过终端支持的监听信息的最大个数,所述监听信息包括:物理下行控制信道(PDCCH)候选或PDCCH信道估计,具体地,PDCCH候选指的是PDCCH盲检。例如,网络为终端分配一个或多个搜索空间,并配置每个搜索空间的初始盲检个数,该初始盲检个数应小于终端支持的最大盲检个数。
即,当监听信息的初始个数为初始盲检个数时,监听信息总数为最大盲检个数;当监听信息的初始个数为初始PDCCH信道估计个数时,监听信息总数为最大PDCCH信道估计个数。
需要说明的是,该搜索空间的监听信息的确定方法既可以应用于终端,也可以应用于基站。
具体地,为了实现上述步骤101,本公开实施例通常采用下列实现方式中的至少一项:
方式一、根据搜索空间的优先级类型信息,确定每个搜索空间的监听信息的第一个数;
需要说明的是,此种实现方式为基于类型优先进行监听信息的第一个数的分配,即优先保证某些类型的搜索空间的监听信息的个数。
因搜索空间有不同类型(公共搜索空间或终端特定搜索空间,Type-0/1/2/3……),搜索不同的下行控制信息(DCI)格式或大小(DCI 0_0,DCI 1_0,DCI 2_1,等),可以依据上述信息对搜索空间进行优先级的排序,当不同搜索空间重叠时,优先保证高优先类型的搜索空间的监听信息的个数,减小低优先类型监听信息的个数,以确保不超过最大支持的监听信息总数。
例如,公共搜索空间优先级高于终端特定搜索空间;某些DCI格式(例 如,DCI 2_0)高于其他DCI格式(例如,DCI 2_2)。
方式二、根据所述监听信息的第二个数,确定每个搜索空间的监听信息的第一个数,所述第二个数为至少两个搜索空间中每个搜索空间的监听信息的第一个数之和与所述终端支持的监听信息总数的差值;
需要说明的是,该第二个数指的是监听信息的超额个数;该种实现方式是基于权值扣除确定监听信息的第一个数,即将超额个数分别在每个搜索空间的监听信息的个数中扣除,具体实现方式为:根据预设配置参数确定每个搜索空间的分配权值;根据大于所述终端支持的监听信息总数的监听信息的第二个数以及所述分配权值,获取每个搜索空间的监听信息的第一个数。
具体地,该预设配置参数包括:搜索空间监听周期、监听信息的初始个数、搜索空间优先级、下行控制信息格式、下行控制信息的长度和搜索空间类型中的至少一项。
因利用不同的预设配置参数,确定每个搜索空间的分配权值的具体方式不同,下面从不同的预设配置参数角度,对根据预设配置参数确定每个搜索空间的分配权值的具体实现分别进行说明如下。
A1、当预设配置参数包括:搜索空间监听周期或预设配置参数包括:搜索空间监听周期和监听信息的初始个数时
具体地,根据预设配置参数确定每个搜索空间的分配权值的实现方式为:
根据预设配置参数,获取每个搜索空间预设时间内的搜索频率;
根据所述搜索频率,获取每个搜索空间的分配权值。
具体地,该预设时间指的是单位时间。
进一步地,获取每个搜索空间预设时间内的搜索频率的方式具体为:
根据公式:
Figure PCTCN2019074408-appb-000001
获取每个搜索空间预设时间内的搜索频率;
其中,F i为第i个搜索空间预设时间内的搜索频率;T i为第i个搜索空间的监听周期;i为搜索空间的编号。
在此种情况下,因利用不同的预设配置参数,根据所述搜索频率,获取每个搜索空间的分配权值的具体方式也会不同,下面从不同的预设配置参数角度,对根据所述搜索频率,获取每个搜索空间的分配权值的具体实现分别进行说明如下。
B1、所述预设配置参数只包括:搜索空间监听周期
所述根据所述搜索频率,获取每个搜索空间的分配权值,包括:
根据公式:
Figure PCTCN2019074408-appb-000002
获取每个搜索空间的分配权值;
其中,P i为第i个搜索空间的分配权值;F i为第i个搜索空间预设时间内的搜索频率;∑为求和函数。
B2、所述预设配置参数包括搜索空间监听周期,还包括监听信息的初始个数
所述根据所述搜索频率,获取每个搜索空间的分配权值,包括:
根据公式:
Figure PCTCN2019074408-appb-000003
获取每个搜索空间的分配权值;
其中,P i为第i个搜索空间的分配权值;F i为第i个搜索空间预设时间内的搜索频率;B i为第i个搜索空间的监听信息的初始个数。
A2、当预设配置参数包括:搜索空间优先级时
具体地,根据预设配置参数确定每个搜索空间的分配权值的实现方式为:
根据公式:
Figure PCTCN2019074408-appb-000004
获取每个搜索空间的分配权值;
其中,P i为第i个搜索空间的分配权值;L i为第i个搜索空间的优先级。
还需要说明的是,每个搜索空间的分配权值可以按照如下公式计算
Figure PCTCN2019074408-appb-000005
上述情况可以看作是式中a,b,c分别取值为0或1的特例。
通过分配不同的a,b,c的值,本公开实施例可以进一步拓展于各种应用场景。
进一步地,根据大于所述终端支持的监听信息总数的监听信息的第二个数以及所述分配权值,获取每个搜索空间的监听信息的第一个数的具体实现方式为:
根据公式:
Figure PCTCN2019074408-appb-000006
获取每个搜索空间的监听信息的第一个数;
其中,B′ i为第i个搜索空间的监听信息的第一个数;B i为第i个搜索空间的监听信息的初始个数;P i为第i个搜索空间的分配权值;M为终端支持的监听信息总数;∑ iB i-M为大于所述终端支持的监听信息总数的监听信息的第二个数;∑为求和函数;C为第一阈值。
还需要说明的是,在某些情况下,会存在某个搜索空间的监听信息的初 始个数小于超额配置的个数,上述公式中,提前配置了一个第一阈值,该第一阈值为搜索空间的监听信息的最小个数,无论怎样配置,搜索空间的监听信息的个数都不能小于该第一阈值;此种方式确保每个搜索空间实际分配到的监听信息的不会超过原来分配的数量,考虑到监听信息的个数与搜索空间关联的控制资源集(CORESET)的资源数有关,分配超过CORESET资源允许的监听信息的个数是没有意义的。
当某些搜索空间的监听信息的初始个数小于其对应需减掉的超额个数时,还应该将这些搜索空间未处理的超额个数分配到其他搜索空间中,具体地,实现方式为:
获取第一搜索空间的监听信息的第三个数;
当所述第三个数大于零时,将所述第三个数分配到除所述第一搜索空间之外的搜索空间中,获取每个搜索空间的监听信息的第一个数;
其中,所述第一搜索空间的监听信息的初始个数小于所述监听信息的第二个数与所述第一搜索空间对应的所述分配权值的乘积;所述第三个数根据公式:
Figure PCTCN2019074408-appb-000007
获取得到;
其中,B i为第i个搜索空间的监听信息的初始个数;P i为第i个搜索空间的分配权值;M为终端支持的监听信息总数。
需要说明的是,在将第三个数分配到除所述第一搜索空间之外的搜索空间中时,可以在除所述第一搜索空间之外的搜索空间中,按照上述的搜索空间分配权值的方式,将第三个数分配给除第一搜索空间之外的搜索空间;也可以在除所述第一搜索空间之外的搜索空间中,将第三个数分配到有足够监听信息剩余个数的搜索空间中,具体地分配方式在本公开实施例中不再进行限定,只要保证第三个数在分配完成后,存在重叠的搜索空间的监听信息的个数之和不超过监听信息总数即可。
例如,以确定盲检个数为例,如果某个搜索空间的初始盲检个数小于其对应的超额个数,则该搜索空间的盲检个数减至C(C为大于或等于0的整数),超额数量与该初始盲检个数之差加上C为透支数,将透支数重新按分配权值分配到其他搜索空间去。
例如,以确定盲检个数为例,盲检总数为40,每个搜索空间的盲检最小 个数为13(即C=13),其中,搜索空间M1的初始盲检个数为20,搜索空间M2的初始盲检个数为15,搜索空间M3的初始盲检个数为13,在利用分配权值分配后,搜索空间M1的盲检个数为17,搜索空间M2的盲检个数为13,搜索空间M2的盲检个数为13,此时,还有3个超额的盲检个数,因搜索空间M2和搜索空间M3已达到了最低盲检个数,此时将3个超额的盲检个数分配给搜索空间M1,最终搜索空间M1的盲检个数为14。
以预设配置参数包括:搜索空间监听周期,且以确定终端的盲检个数为例,对此种实现方式举例说明如下:
假设终端支持的最大盲检次数M=44,终端配置了多个搜索空间,例如,搜索空间S1的监听周期为2,搜索空间S2的监听周期为5,搜索空间S3的监听周期为10,每个搜索空间的初始盲检个数都配为20,当三个搜索空间在时间上重叠时,计算每个搜索空间的实际盲检次数:
首先计算超额个数为16;
计算每个搜索空间的分配权值:
S1的分配权值为:5/8;S2的分配权值为:1/4;S3的分配权值为:1/8;
每个搜索空间实际分配盲检个数为:
S1的实际分配盲检个数为:10个;S2的实际分配盲检个数为:16个;S3的实际分配盲检个数为:18个。
按照本公开实施例的分配方式,总盲检数量不超过上限44个,且长周期的搜索空间保持了较多的盲检数,而短周期的搜索空间则丢弃了较多的盲检数,保证了公平性,确保长周期不会长期分配不到盲检个数。
方式三、根据所述终端支持的监听信息总数,确定每个搜索空间的监听信息的第一个数
需要说明的是,该种实现方式是按每个搜索空间的比例将监听信息总数进行重新分配,具体地,实现方式为:根据预设配置参数确定每个搜索空间的分配权值;根据所述分配权值,确定每个搜索空间的分配比例;根据所述分配比例以及所述终端支持的监听信息总数,确定每个搜索空间的监听信息的第一个数。
具体地,该预设配置参数包括:搜索空间监听周期、监听信息的初始个 数、搜索空间优先级、下行控制信息格式、下行控制信息的长度和搜索空间类型中的至少一项。
因利用不同的预设配置参数,根据预设配置参数确定每个搜索空间的分配权值的具体方式不同,下面从不同的预设配置参数角度,对根据预设配置参数确定每个搜索空间的分配权值的具体实现分别进行说明如下。

获取每个搜索空间预设时间内的搜索频率;
其中,F i为第i个搜索空间预设时间内的搜索频率;T i为第i个搜索空间的监听周期;i为搜索空间的编号。
在此种情况下,因利用不同的预设配置参数,根据所述搜索频率,获取每个搜索空间的分配权值的具体方式也会不同,下面从不同的预设配置参数角度,对根据所述搜索频率,获取每个搜索空间的分配权值的具体实现分别进行说明如下。

还需要说明的是,每个搜索空间的分配权值可以按照如下公式计算

其中,B′ i为第i个搜索空间的监听信息的第一个数;U i为第i个搜索空间的分配比例;M为终端支持的监听信息总数。
需要说明的是,本公开实施例的上述描述指的是当终端监听至少两个搜索空间、且所述至少两个搜索空间的监听信息的初始个数之和大于所述终端支持的监听信息总数时,重新确定搜索空间的监听信息的个数的方式,当在任一单位时间点,终端只需要监听一个搜索空间,或虽然有多个搜索空间,但所有搜索空间的监听信息的初始个数之和不超过终端支持的监听信息总数,则终端按照网络配置的监听信息的初始个数分别进行监听,本公开实施例,支持对不同周期的搜索空间的盲检数以及信道估计数分配进行超订(overbooking),即每个搜索空间可以单独分配不超过终端支持的最大盲检数以及信道估计数,从而可以充分利用终端的处理能力,提高系统资源利用率并降低分配阻塞概率。当在多个搜索空间在时间上重叠的时候,按照本公开实施例提供的方法在搜索空间之间分配盲检数或信道评估数,以确保所有搜索空间上的盲检总数或信道估计总数之和不超过终端支持的最大能力。
需要说明的是,本公开实施例也可适用于其他任何周期不同的资源间之间超额分配有限资源的情况,例如,在多个载波同时发送周期信号时的功率分配等。
