技术领域
本公开涉及通信领域,特别涉及一种资源配置方法和装置、基站、通信系统和存储介质。
背景技术
5G网络单基站的能耗可达LTE(Long Term Evolution,长期演进)网络中单基站的能耗的3倍以上,且由于5G网络的频谱更高且密度更大,因此5G网络的总能耗接近LTE网络的4倍,能耗成本占比几近网络运营总成本的一半。
通过灵活关断天线端口和调节天线发射功率,可以尽可能降低基站发送信号的网络能耗。目前,为每个CSI(Channel State Information,信道状态信息)-RS(Reference Signal,参考信号)资源配置一个端口数和一个功率偏移量。为了提高CSI-RS资源的配置效率,可对多个CSI-RS资源同时进行配置。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的,决不作为对本公开及其应用或使用的任何限制。基于本公开中的实施例,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,都属于本公开保护的范围。

同时,应当明白,为了便于描述,附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论,但在适当情况下,所述技术、方法和设备应当被视为授权说明书的一部分。
在这里示出和讨论的所有示例中,任何具体值应被解释为仅仅是示例性的,而不是作为限制。因此,示例性实施例的其它示例可以具有不同的值。
应注意到:相似的标号和字母在下面的附图中表示类似项,因此,一旦某一项在一个附图中被定义,则在随后的附图中不需要对其进行进一步讨论。
发明人注意到,在对多个CSI-RS资源同时进行配置的场景下,由于需要配置多个不同端口资源,按照现有标准,还需要配置相应的CDM(Code Division Multiplexing,码分复用)类型,时序频域位置等信息,即需要配置参数较多;同时,在CSI上报配置中,由于需要上报多个CSI-RS,也需要同时配置多个上报信息,从而增加了网络负担。例如,同时测量N个天线端口数下的CSI和M个不同发射功率下的CSI-RS将使得整体复杂度和网络信令开销变为原来的N*M倍。
据此,本公开提供一种资源配置方法,通过CSI-RS资源配置和CSI上报配置,在完成多个CSI测量的同时还能有效减小网络负担、降低测量复杂度。
图1为本公开一个实施例的资源配置方法的流程示意图。在一些实施例中,下列的资源配置方法由资源配置装置执行。
在步骤101,对多个CSI-RS资源中的每个CSI-RS资源进行资源配置(Resource Configuration),以得到资源配置结果,其中每个CSI-RS资源的端口数总数和功率控制偏移值总数中的至少一项大于1。
需要说明的是,多个CSI-RS资源中的每个CSI-RS资源具有相同的端口数(Number of ports)。
在一些实施例中,对多个CSI-RS资源中的每个CSI-RS资源进行资源配置的流程包括如图2所示的流程。
在步骤201,判断是否为多个CSI-RS资源中的第i个CSI-RS资源配置预设的多个端口数,1≤i≤N,N为多个CSI-RS资源的总数。
若为第i个CSI-RS资源配置预设的多个端口数,则执行步骤202;若为第i个CSI-RS资源配置预设的1个端口数,则执行步骤203。
在步骤202、为第i个CSI-RS资源配置预设的多个端口数。
在一些实施例中,在第i个CSI-RS资源的端口数列表中写入预设的多个端口数,或者在第i个CSI-RS资源的端口数列表中写入预设的多个端口数中的最大值,并将第i个CSI-RS资源的多图样标志(multipatternflag)设置为预设值。例如,预设值为1。
例如,为第i个CSI-RS资源配置的端口数为8、12、16,则第i个CSI-RS资源的端口数列表中包括{8、12、16}。
又例如,为第i个CSI-RS资源配置的最大端口数为16,则第i个CSI-RS资源的端口数列表中仅包括{16},同时多图样标志=1。这意味着为第i个CSI-RS资源配置的 多个端口数为1、2、4、8、12、16。
在步骤203,为第i个CSI-RS资源配置预设的1个端口数。
在一些实施例中,在第i个CSI-RS资源的端口数列表中写入预设的1个端口数。
需要说明的是,在为第i个CSI-RS资源配置预设的1个端口数的情况下,第i个CSI-RS资源的端口数列表中仅包括1个端口数,且多图样标志=0或多图样标志未配置。
在一些实施例中,在图2的基础上,对多个CSI-RS资源中的每个CSI-RS资源进行资源配置的流程还包括如图3所示的流程。
在步骤301,判断是否为第i个CSI-RS资源配置预设的多个功率控制偏移值(powerControlOffset)。
需要说明的是,功率控制偏移值是相对于PDSCH(Physical Downlink Shared Channel,物理下行共享信道)的发射功率的偏移量。
若为第i个CSI-RS资源配置预设的多个功率控制偏移值,则执行步骤302;若为第i个CSI-RS资源配置预设的1个功率控制偏移值,则执行步骤303。
在步骤302,为第i个CSI-RS资源配置预设的多个功率控制偏移值。
在一些实施例中,在第i个CSI-RS资源的功率列表中写入预设的多个功率控制偏移值,或者为第i个CSI-RS资源配置预设的多个功率控制偏移值的功率控制偏移值上限(powerControlOffsetUpperLimit)和功率控制偏移值下限(powerControlOffsetLowerLimit)。
例如,为第i个CSI-RS资源配置的功率控制偏移值为-3、-2、-1、0、1、2、3,则第i个CSI-RS资源的功率控制偏移值列表包括{-3、-2、-1、0、1、2、3}。
又例如,为第i个CSI-RS资源配置的功率控制偏移值为-3、-2、-1、0、1、2、3,其中最大值为3,最小值为-3,则配置第i个CSI-RS资源的功率控制偏移值下限为-3,第i个CSI-RS资源的功率控制偏移值上限为3,从而得到的功率控制偏移值区间为[-3,3]。
在步骤303、为第i个CSI-RS资源配置预设的1个功率控制偏移值。
需要说明的是,在为第i个CSI-RS资源配置预设的1个功率控制偏移值的情况下,第i个CSI-RS资源的功率控制偏移值列表中仅包括1个功率控制偏移值。
在步骤102,根据资源配置结果对多个CSI-RS资源进行CSI上报配置(CSI report Configuration),以得到CSI上报配置结果。
在一些实施例中,根据资源配置结果对多个CSI-RS资源进行CSI上报配置的流程如图4所示。
在步骤401,判断每个CSI-RS资源是否配置多个端口数。
在一些实施例中,判断每个CSI-RS资源的端口数列表中是否配置多个端口数。若每个CSI-RS资源的端口数列表中包括多个端口数,则确定每个CSI-RS资源配置多个端口数。
在一些实施例中,若每个CSI-RS资源的端口数列表中仅包括1个端口数,则进一步判断每个CSI-RS资源的多图样标志是否为预设值。若每个CSI-RS资源的多图样标志为预设值,则确定每个CSI-RS资源配置多个端口数,且将该端口数列表中的1个端口数作为最大端口数。
例如,预设值为1。
若每个CSI-RS资源配置多个端口数,则执行步骤402;若每个CSI-RS资源配置1个端口数,则执行步骤405。
在步骤402,将多个端口数中的至少部分端口数作为多个目标端口数。
这里需要说明的是,在每个CSI-RS资源的端口数列表中包括多个端口数的情况下,将多个端口数作为多个目标端口数。
在每个CSI-RS资源的端口数列表中包括最大端口数的情况下,在由最大端口数所确定的多个端口数中,选择预定数量个端口数作为多个目标端口数。
在步骤403,根据多个CSI-RS资源生成与多个目标端口数一一对应的多个第一子配置(sub-configuration)信息,其中每个第一子配置信息包括对应的目标端口数。
在一些实施例中,每个第一子配置信息还包括每个CSI-RS资源的资源标识。
在步骤404,为每个第一子配置信息配置一个或多个发射功率偏移值。
例如,在一个资源集合中包括2个CSI-RS资源,即CSI-RS#1和CSI-RS#2。CSI-RS#1配置的端口数为{8,12,16},功率控制偏移值范围为[-2,0]dB。CSI-RS#2配置的端口数为{8,12,16},功率控制偏移值范围为[-1,1]dB。
在CSI上报配置中生成如下的三个子配置信息。
·sub#1(#ports=8):{CSI-RS#1,#2}
·sub#2(#ports=12):{CSI-RS#1,#2}
·sub#3(#ports=16):{CSI-RS#1,#2}
需要说明的是,由于每个子配置信息中包括相同的CSI-RS资源的资源标识,因 此每个子配置信息也可不包括CSI-RS资源的资源标识。
接下来,在这三个子配置信息中,为第一个子配置信息配置的发射功率偏移值为{-2},为第二个子配置信息配置的发射功率偏移值为{-2,0},为第三个子配置信息配置的发射功率偏移值为{1}。然后将配置的发射功率偏移值{-2}、{-2,0}、{1}发送给用户终端。用户终端基于上述三个子配置信息和为每个子配置信息配置的发射功率偏移值,确定需要检测的CSI-RS资源为如下:
·CSI-RS#1,端口8,发射功率偏移值为-2dB
·CSI-RS#1,端口12,发射功率偏移值为-2dB
·CSI-RS#1,端口12,发射功率偏移值为0dB
·CSI-RS#2,端口12,发射功率偏移值为0dB
·CSI-RS#2,端口16,发射功率偏移值为1dB
又例如,在一个资源集合中包括2个CSI-RS资源,即CSI-RS#1和CSI-RS#2。CSI-RS#1配置的最大端口数为16,功率控制偏移值范围为[-2,0]dB。CSI-RS#2配置的最大端口数为16,功率控制偏移值范围为[-1,1]dB。
在由最大端口数为16确定的多个端口数中,选择三个端口数,即{8,12,16},进而在CSI上报配置中生成如下的三个子配置信息。
·sub#1(#ports=8):{CSI-RS#1,#2}
·sub#2(#ports=12):{CSI-RS#1,#2}
·sub#3(#ports=16):{CSI-RS#1,#2}
需要说明的是,由于每个子配置信息中包括相同的CSI-RS资源的资源标识,因此每个子配置信息也可不包括CSI-RS资源的资源标识。
接下来,在这三个子配置信息中,为第一个子配置信息配置的发射功率偏移值为{-2},为第二个子配置信息配置的发射功率偏移值为{-2,0},为第三个子配置信息配置的发射功率偏移值为{1}。然后将配置的发射功率偏移值{-2}、{-2,0}、{1}发送给用户终端。用户终端基于上述三个子配置信息和为每个子配置信息配置的发射功率偏移值,确定需要检测的CSI-RS资源为如下:
·CSI-RS#1,端口8,发射功率偏移值为-2dB
·CSI-RS#1,端口12,发射功率偏移值为-2dB
·CSI-RS#1,端口12,发射功率偏移值为0dB
·CSI-RS#2,端口12,发射功率偏移值为0dB
·CSI-RS#2,端口16,发射功率偏移值为1dB
在步骤405,判断每个CSI-RS资源是否配置多个功率控制偏移值。
若每个CSI-RS资源配置多个功率控制偏移值,则可根据预设配置执行步骤406或步骤408。若每个CSI-RS资源包括1个功率控制偏移值,执行步骤409。
在步骤406,根据多个CSI-RS资源生成多个第二子配置信息,其中每个第二子配置信息包括多个CSI-RS资源中的至少一个CSI-RS资源的资源标识,和与至少一个CSI-RS资源的资源标识对应的功率偏移值,任两个第二子配置信息之间没有交集。
在步骤407,为每个第二子配置信息配置一个或多个发射功率偏移值。
例如,在一个资源集合中包括2个CSI-RS资源,即CSI-RS#1和CSI-RS#2。CSI-RS#1和CSI-RS#2配置的端口数均为16(端口图样不同),CSI-RS#1的功率控制偏移值范围为[-3,3]dB。CSI-RS#2的功率控制偏移值范围为[-2,5]dB。
在CSI上报配置中生成如下的三个子配置信息。
·sub#1(power-offset=-3):{CSI-RS#1}
·sub#2(power-offset=-2,-1,1,2,3):{CSI-RS#1,#2}
·sub#3(power-offset=4,5):{CSI-RS#2}
接下来,在这三个子配置信息中,为第一个子配置信息配置的发射功率偏移值为{-3},为第二个子配置信息配置的发射功率偏移值为{2},为第三个子配置信息配置的发射功率偏移值为{5}。然后将配置的发射功率偏移值{-3}、{2}、{5}发送给用户终端。用户终端基于上述三个子配置信息和为每个子配置信息配置的发射功率偏移值,确定需要检测的CSI-RS资源为如下:
·CSI-RS#1,端口16,发射功率偏移值为-3dB
·CSI-RS#1,端口16,发射功率偏移值为2dB
·CSI-RS#2,端口16,发射功率偏移值为2dB
·CSI-RS#2,端口16,发射功率偏移值为5dB
在步骤408,为每个CSI-RS资源配置一个或多个发射功率偏移值。
例如,在一个资源集合中包括2个CSI-RS资源,即CSI-RS#1和CSI-RS#2。CSI-RS#1和CSI-RS#2配置的端口数均为16(端口图样不同),CSI-RS#1的功率控制偏移值范围为[-3,3]dB。CSI-RS#2的功率控制偏移值范围为[-2,5]dB。
接下来,为CSI-RS#1和CSI-RS#2配置的发射功率偏移值为{-3}、{2}、{5}。然后将配置的发射功率偏移值{-3}、{2}、{5}发送给用户终端。用户终端基于为CSI-RS#1 和CSI-RS#2配置的发射功率偏移值{-3}、{2}、{5},确定需要检测的CSI-RS资源为如下:
·CSI-RS#1,端口16,发射功率偏移值为-3dB
·CSI-RS#1,端口16,发射功率偏移值为2dB
·CSI-RS#2,端口16,发射功率偏移值为2dB
·CSI-RS#2,端口16,发射功率偏移值为5dB
在步骤409,按照现有的预设标准流程进行处理。
由于现有标准流程是本领域技术人员所了解的,因此这里不展开描述。
返回图1。在步骤103,将CSI上报配置结果发送给用户终端。
在上述实施例提供的资源配置方法中,通过CSI-RS资源配置,每个CSI-RS资源的端口数总数和功率控制偏移值总数中的至少一项大于1,进而在CSI-RS资源配置的基础上进行CSI上报配置。由此在完成多个CSI测量的同时还能有效减小网络负担、降低测量复杂度。
此外,本公开利用较小的开销获得了较为灵活的资源配置方法,从而具备更高的灵活性和更小的颗粒度,有效提高资源配置效率。

在一些实施例中,第一处理模块51被配置为判断是否为多个CSI-RS资源中的第i个CSI-RS资源配置预设的多个端口数,1≤i≤N,N为多个CSI-RS资源的总数。若为第i个CSI-RS资源配置预设的多个端口数,则第一处理模块51在第i个CSI-RS资源的端口数列表中写入预设的多个端口数,或者在第i个CSI-RS资源的端口数列表中写入预设的多个端口数中的最大值,并将第i个CSI-RS资源的多图样标志设置为预设值。
例如,预设值为1。
在一些实施例中,第一处理模块51被配置为判断是否为第i个CSI-RS资源配置预设的多个功率控制偏移值。若为第i个CSI-RS资源配置预设的多个功率控制偏 移值,则第一处理模块51在第i个CSI-RS资源的功率列表中写入预设的多个功率控制偏移值,或者为第i个CSI-RS资源配置预设的多个功率控制偏移值的功率控制偏移值上限和功率控制偏移值下限。

在这种情况下,选择预定数量个端口数作为多个目标端口数。
在一些实施例中,第二处理模块52被配置为若每个CSI-RS资源仅包括1个端口数,则判断每个CSI-RS资源是否配置多个功率控制偏移值。若每个CSI-RS资源包括多个功率控制偏移值,则第二处理模块52根据多个CSI-RS资源生成多个第二子配置信息,其中每个第二子配置信息包括多个CSI-RS资源中的至少一个CSI-RS资源的资源标识,和与至少一个CSI-RS资源的资源标识对应的功率偏移值,任两个第二子配置信息之间没有交集,并为每个第二子配置信息配置一个或多个发射功率偏移值。
在一些实施例中,第二处理模块52被配置为若每个CSI-RS资源仅包括1个端 口数,则判断每个CSI-RS资源是否配置多个功率控制偏移值。若每个CSI-RS资源包括多个功率控制偏移值,则第二处理模块52为每个CSI-RS资源配置一个或多个发射功率偏移值。
