Description

一种通信质量测量的方法和装置
技术领域
本发明涉及通信技术领域, 特别涉及一种通信质量测量的方法和装置。
背景技术
在通信技术领域中,信号通常可以划分为两类, 一类信号携带来自高层的 信息, 另一类信号则不携带来自高层的信息, 该类信号通常用于辅助或者指示 前一类信号的接收。 信号的发射功率对于上述两类信号都是非常重要的参数, 例如: 参考信号的功率可以用于导出路径损耗估计值, 该路径损耗估计值可以 作为开环控制的一部分实现上行功率控制, 或者作为小区(或者发射节点, 或 者接收节点)选择的基础。 物理下行共享信道(PDSCH, Physical Downlink Shared CHannel )信号相对于参考信号 (如: 小区特定的参考信号 (CRS , Cell-Specific Reference Signal )或者信道状态信息参考信号 (CSI-RS, Channel State Information Reference Signal)的功率比值, 可以用于导出信道状态信息 ( CSI, Channel State Information ), 便于实现调度和链路自适应。
在现有长期演进 ( LTE, Long Time Evolution ) R8—R11版本中, 与功率 有关的参数是由基站或者网络侧确定,并通过高层信令通知给用户设备(UE , User Equipment )。 由于传统基站天线配置具有固定的下倾角,上行和下行链路 经历类似的路径损耗, 从而下行路径损耗可以很好地用于估计上行路径损耗。 因此, 上述基站或者网络侧发送的功率有关的参数可以不区分天线端口, 尤其 是多个天线端口的情况, 不区分天线端口的情况下,通过下行路径损耗可以很 好地用于估计上行路径损耗。该技术对于传统基站天线配置特别是各个天线端 口发射功率相同的情况可以很好的工作。另一方面,用户设备( User Equipment, UE ) 上报的本小区 /节点或者邻小区 /节点的参考信号接收功率 (RSRP , Reference Signal Received Power )可以用于基站或者演进节点 B( evolved Node, eNB ) 为 UE选择服务小区或者节点。 现有技术中 RSRP是由不同天线口之间进 行平均从而得到估计。
为了降低系统费用同时达到更高的系统容量和覆盖要求, 有源天线系统 ( AAS , Active Antenna System )在实践中已广泛部署, 目前即将启动的 LTE R 12 标准正在考虑引入 AAS系统之后对通信性能的增强。 有别于传统的基站天线, AAS进一步提供了天线垂直向的设计自由度,上行和下行链路可以采用独立的 下倾角, 并且, 不同天线端口的功率可能不同。 此外, 对于 AAS基站而言, 即 使相同数量的天线端口, 其天线阵列结构也可能不同。从而相同编号的天线端 口, 在不同阵列结构的天线端口也可能有不同的发射功率。 在这种情况下, 现 有技术中基于下行参考信号接收功率实现功率控制, 或者小区 /节点选择的方 法将不再有效。 现有技术中, 无法正确区分天线口发射功率不同的情况, 不能 提供准确有效估计上行路径损耗, 以及估计信道状态信息的技术方案。

具体实施方式
下面将结合本发明实施例中的附图,对本发明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发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 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, 都属于本发明保护的范围。
实施例一
本发明实施例提供了一种通信质量测量的方法,如图 1所示, 所述方法包 括:
步骤 S01 ,确定参考信号资源配置信息,所述参考信号资源配置信息包括: 参考信号端口配置信息,其中所述参考信号端口配置信息用于指示所述参考信 号端口到端口组的映射;
其中, 该操作具体可以是由基站或者网络侧 (例如通用陆地无线接入 (UTRAN , Universal Terrestrial Radio Access Network) ); 或者演进的 UTRAN(Evolved UTRAN), 或者演进节点 B ( evolved node B )执行。
当所述参考信号资源配置信息包括: 参考信号端口配置信息, 可选的, 参 考信号资源配置信息还可以包括: 至少一个端口组的参考信号功率信息时, 将 该参考信号资源配置信息发送给用户设备(UE, User Equipment ), 使得用户 设备根据该参考信号资源配置信息获取信号质量测量信息,由于参考信号端口 被分配到多个组, UE可以根据其中一个端口组或者多个端口组的参考信号质 量处理得到最终的信号质量测量信息,使得 UE侧可以对端口根据不同的端口 组进行区分, 不同于现有技术中不能区分不同端口的发射功率的情况。 因而, 该方案获取的信号质量测量信息,可以使得 UE进行更为准确的小区选择和上 行功率控制。
还需要理解的是,对于所述参考信号资源配置信息中包括的参考信号端口 配置信息的详细说明, 可以参考实施例二中步骤 101中的说明。

进一步, 将参考信号资源配置信息发送给用户侧 UE, UE可以根据其中 至少一个端口组的参考信号质量处理得到最终的信号质量测量信息, 使得 UE 侧可以将端口根据不同的端口组进行区分,不同于现有技术中不能区分不同端 口的发射功率的情况。 使得 UE能够获取的信号质量测量信息, 可以使得 UE 进行更为准确的小区选择和上行功率控制。

具体的,所述向用户设备发送滤波器系数信息,可以是与步骤 S02中所述 将所确定的参考信号资源配置信息发送给用户设备在同一时间发送,如在相同 的子帧发送;也可以是与步骤 S02中所述将所确定的参考信号资源配置信息发 送给用户设备之前或者之后发送;所述滤波器系数信息与所述参考信号资源配 置信息可以在相同或者不同的高层信令如 RRC 信令的信元 (Information Element,简称 IE )或者下行控制信息( Downlink Control Information,简称 DCI ) 中发送。
可选的, 所述方法还包括:
步骤 S05: 接收所述用户设备发送的上行物理信道或者上行物理信号, 其 中所述上行物理信道或者上行物理信号的发射功率为所述用户设备根据所述 路损估计值计算得到的。
可选的, 所述参考信号资源配置信息还包括: 至少两个端口组的参考信号 功率信息,用于所述用户设备根据所述参考信号端口配置信息并结合所述至少 两个端口组的参考信号功率信息, 获取所述信号质量测量信息;
其中, 所述至少两个端口组的参考信号功率信息, 包括:
第一端口组的参考信号功率,以及剩余端口组中每一个端口组的参考信号 功率相对于所述第一端口组的参考信号功率的比值;
或者, 第一端口组的参考信号功率, 以及剩余端口组中每一个端口组的参 考信号功率相对于所述第一端口组的参考信号功率的差分。

实施例二
本发明实施例提供了一种用于通信质量测量的方法,如图 2所示, 该方法 包括:
步骤 101 , 接收基站发送的参考信号资源配置信息, 所述参考信号资源配 置信息包括参考信号端口配置信息,其中所述参考信号端口配置信息用于指示 参考信号端口到端口组的映射关系;
具体的, UE接收参考信号资源配置信息, 可以是 UE通过高层信令 (如: 无线资源控制 (RRC, Radio Resource Control )信令)或者动态信令 (如: 下行 控制信息 (DCI, Downlink Control Information ) ), 接收 eNB通知的参考信 号资源配置信息, 或者基于小区标识 (ID, Identity )得到参考信号的资源配 置信息。 所述高层信令可以通过物理下行共享信道( Physical Downlink Shared Channel, 简称 PDSCH )等数据信道发送; 所述动态信令如 DCI通过物理下行 控制信道 ( Physical Downlink Control Channel, 简称 PDCCH ) 或者增强的 PDCCH ( Enhanced PDCCH, 简称 ePDCCH )等控制信道发送。
需要理解的是, 参考信号端口配置信息, 用于指示参考信号端口到端口组 的映射, 参考信号端口到端口组中的映射关系可以是预定义的, 为基站和用户 设备所共知, 因此,基站侧和用户设备侧都可以识别出该参考信号端口配置消 息。
还需要理解的是,通过参考信号端口组与对应端口的映射关系信息和端口 组的映射索引, 可以唯一确定该端口组中包括的端口, 如下表 1至 3中所示, 在获知参考信号端口组与对应端口的映射关系信息和端口组的映射索引,设备 可以获知对应的端口组中的端口。其中,端口组中包括的端口可以是预定义的, 对于不同的索引, 预定义的端口组可以根据规划得到。 需要说明的是, 一个参 考信号端口与一个天线端口相对应, 一个天线端口对应一个参考信号端口。 天 线信号端口的信道信息根据测量参考信号端口得到。 因此,通常所述预定义的 端口组可以根据天线端口阵列配置规划得到。
一个参考信号端口或者天线端口往往与一个物理天线,或者一个虚拟天线 相对应, 其中所说的虚拟天线可以通过多个物理天线的加权组合得到。 实际的 天线部署可能具有不同的天线配置和天线端口阵列形式。 例如, 图 3所示为不 同的均匀线阵(ULA, Uniform Linear Array )天线端口阵列配置。 其中, 天线 端口阵列 A为 2行 4列的均匀线阵,天线端口阵列 B为 2行 8列的均匀线阵, 天 线端口阵列 c为 4行 4列的均匀线阵; 尽管天线端口阵列 B与阵列 C都具有 16个端口,但是其阵列形式也不同。再如图 4所示为不同的交叉极化(XPO , Cross-polarization, )天线阵配置。 其中, 天线端口阵列 A为 2行 2列的交叉极 化天线阵,天线端口阵列 B为 2行 4列的均匀线阵, 天线端口阵列 C为 4行 2 列的均匀线阵, 不同的极化天线可以处于相同的列; 尽管天线端口阵列 B 与 阵列 C都具有 16个端口, 但是其阵列形式也不同。 以下天线端口阵列简称天 线阵列。
可选地, 作为另一实施例, 所述参考信号端口配置信息, 包括参考信号端 口数和映射索引,其中所述映射索引用于指示参考信号端口组与对应端口的映 射。 以如图 3中的天线阵列 A和如图 4中的天线阵列 A所示的 8天线阵列为 例, 所述参考信号端口配置信息, 包括参考信号端口数为 8 和映射索引为 0 或者 1。 其中所述预定义的参考信号端口到端口组中的映射关系可以通过函数 定义, 也可以通过预定义的表格规定。 例如表格 1中所示, 第一行可以是图 3 中天线阵列 A的参考信号端口配置信息, 该映射指示信息中包括: 参考信号 端口数为 8个, 映射索引为 0, 端口组为 0和 1两组。 表格 1中第二行可以是 图 4中天线阵列 A的参考信号端口配置信息, 该映射指示信息中包括: 参考 信号端口数为 8个, 映射索引为 1 , 端口组为 0和 1两组。 需要指出的是, 本 实施例中参考信号端口和参考信号端口组可以与天线端口和天线端口组互换。

进一步, 当映射索引值为 0时, 端口组 0包含参考信号端口 (或者天线端 口) 0,3,4和 7, 端口组 1包含参考信号端口 (或者天线端口) 1,2,5和 6; 当映 射索引值为 1时, 端口组 0包含参考信号端口 (或者天线端口) 0,1,4和 5 , 端 口组 1包含参考信号端口 (或者天线端口) 2,3,6和 7。
以如图 3中的天线阵列 B或者 C和如图 4中的天线阵列 B或者 C所示的 16天线阵列为例, 所述参考信号端口配置信息, 包括参考信号端口数为 16和 映射索引为 0或者 1或者 2或者 3。 其中所述预定义的参考信号端口到端口组 中的映射关系可以通过函数定义, 也可以通过预定义的表格规定。 例如表格 2 所示:

3 0,3,12,15 1,2,13,14 4,7,8,11 5,6,9,10
其中, 图 3中天线阵列 B可以假设为表 2中第一行, 即映射索引值为 0, 端口组 0包含参考信号端口 (或者天线端口) 0,3,8和 11 , 端口组 1包含参考 信号端口 (或者天线端口) 4,7,12和 15 , 端口组 2包含参考信号端口 (或者天 线端口) 1,2,9和 10, 端口组 3包含参考信号端口 (或者天线端口) 5,6,13和 14。 当映射索引值为 1或 2或 3时,各个端口组包含的参考信号端口可以由上 述表格依次类推。
可选的, 作为另一实施例, 所述参考信号端口配置信息, 可以包括端口组 映射双索引 (m, n )。 此时, 所述预定义的参考信号端口到端口组中的映射关 系可以通过函数定义, 也可以通过预定义的表格规定。 例如表格 3所示: 表格 3-端口到端口组的映射
Figure imgf000028_0001
可选的, 双索引(m, n)可以指示参考信号端口数为 m和 n的乘积。
进一步地, 所述双索引信息, 可以进行联合编码, 例如, 上述表格 3中的 双索引的联合编码, 如表格 3a或者 3b所示。

可选的, 端口组的划分可以是以 4个参考信号端口 (或者天线端口) 为一 个端口组。
需要进一步指出的是, 端口组的划分也可以不限于含有 4个参考信号端口 的端口组, 还可以是 2或 8个或者其他构成形式的端口组。 同时, 每个端口组 内含有的参考信号端口号,也不限于上述取值, 可以根据实际的天线配置或者 部署灵活选择。上述预定义的端口组映射以及映射指示信息, 可以使得系统能 够自适应更多的天线配置和天线阵列部署。

具体地, 所述参考信号或者信号, 具体可以包括小区特定参考信号 CSR; 或者, 信道状态信息参考信号 (CSI-RS, Channel State Information Reference Signal )或者解调参考信号 (DMRS, DeModulation Reference signal ), 但不 限于当前的举例。

以表 2中的映射索引为 0举例, 此时端口组 0含有的参考信号端口为 0, 3 , 8和 11。 其中每个天线端口的复数 RSRP测量可以为相邻两个参考信号资 源单元(RE, Resource Element )的相关, 其中, 这里的相邻的两个 RE可以是 指频域上相邻的两个 RE,或者时域上相邻的两个 RE,或者是时频域上相邻的 两个 RE。
Figure imgf000031_0001
其中, )为标号为 m的参考信号 RE上的信道估计; 是在测量带 宽内可利用的参考信号 RE的样本总数; p为所述指定的一个端口组中参考信 号端口号, r为接收天线的索引。 通过组合 (combine) ^^?^,^可以得到天线端 口组 0对应的 RSRP , 得到第 r个接收天线第 p个端口的参考信号接收功率
RSRP(r, p) 并通过组合 Λ , ^)得到所述 RSRP„ 例如: 上述 W^(r, ^)对各个端 口 p和接收天线作线性(相关或者非相关)平均后取绝对值可以得到端口组 0 对应的 RSRP; 或者上述 ^P(r, ^)对其中某一个端口 p和各个接收天线作线性 (相干或者非相关)平均后取绝对值可以得到端口组 0对应的 RSRP。 依次类 推, 也可以利用其它端口组的参考信号得到 RSRP。 本实施例步骤 103中所述用于得到 RSRP的端口组以及该端口组中的端口 可以是预定义的 (例如: 端口组 0, 以及端口组 0中的端口 0 , 或者是端口组 0中的端口 0和 3 , 或者是该端口组 0中的所有端口, 或者其它)或者由基站 eNB通过高层信令如 RRC信令或者下行控制信息通知。 以上基于一个端口组 或者一个端口组中的部分或者全部端口得到 RSRP, 不必逐端口测量 RSRP, 可以降低 UE的 RSRP测量的实现复杂性, 同时, 端口组预定义或者通知, 使 得 UE和 eNB对测量的理解一致, 从而保证 RSRP测量的一致性。 同时, 不同 的端口组可以彼此独立指示其功率,充分利用了图 3和图 4所示的天线配置和 天线阵列的结构,可以适应天线结构的变化灵活指示,从而可以保证基站 eNB 能够自适应多种天线配置和天线阵列。
可选的, 当步骤 101 中 UE接收的参考信号资源配置信息中包括的一个或 者多个端口组的参考信号功率信息,用作指示对应端口组中各个端口的参考信 号功率。
以 16个参考信号端口为例, 4端口组的参考信号功率可以如表 4所示: 表格 4一端口组的参考信号功率表
Figure imgf000032_0001
此时, 端口组 0包含的参考信号端口的功率为 ρθ, 端口组 1,2和 3中包含 的参考信号端口的功率可以依次类推, 分别为 pl ,p2和 p3。
或者, 上述一个或者多个端口组的参考信号功率信息, 还可以用其中一个 端口组(例如端口组 0 ) 的参考信号功率以及其它一个 (例如端口组 1)或者多 个端口组 (例如端口组 1 , 2, 3)相对于该端口组(例如端口组 0 ) 的参考信号 功率比值共同表示; 例如端口组 0的参考信号功率为 ρθ, 端口组 1 , 2和 3相 对于端口组 0的参考信号功率比值分别为 pl, p2和 p3。此时 UE可以得到端口 组 1 , 2和 3的参考信号功率分别为 p0*pl, p0 *p2和 p0*p3。
此外, 所述一个或者多个端口组的参考信号功率信息, 还可以用于其中一 个端口组(例如端口组 0 ) 的参考信号功率以及其它一个 (例如端口组 1)或者 多个端口组 (例如端口组 1 , 2, 3)相对于该端口组(例如端口组 0 ) 的参考信 号功率的差分来表示; 例如端口组 0的参考信号功率为 ρθ, 端口组 1 , 2和 3 相对于端口组 0的参考信号功率的差分分别为 dl,d2和 d3。此时 UE可以得到 端口组 1 , 2和 3的参考信号功率分别为 ρθ+dl, p0+d2和 p0+d3。
上述采用端口组分别指示参考信号功率信息, 除了可以避免逐端口指示参 考信号功率从而减少信令开销之外,端口组内各个端口采用统一的功率指示而 不同的端口组可以彼此独立指示其功率,充分利用了天线配置或者天线阵列的 结构,从而可以使得系统能够根据天线配置或者天线阵列结构灵活选择参考信 号功率。 同时, 需要进一步指出的是, 尽管端口组的划分不限于含有 4个参考 信号端口的端口组, 上述表格 1 , 2, 3中的端口组划分以及各个端口的构成可 以进一步使得图 3或者图 4中的天线阵列具有关于阵列结构对称的功率,即各 个端口相对于阵列可以具有对称的权重, 利用该权重的对称性, 可以降低波束 赋形或者旁瓣抑制的设计复杂性。
进一步,以上所述参考信号功率也可以用每资源单元的能量( EPRE, Energy Per Resource Element )表示。
可选的, 所述至少两个端口组的参考信号功率信息, 包括:

其中, 为指定端口组的信号质量测量信息, 其中, g为指定端口组的编 号, n为指定端口组的个数, 《≥2; 为指定端口组的参考信号功率, 其中, 指定端口组的参考信号功率根据所述至少两个端口组的参考信号功率信息得 到。 以上所述多个端口组可以是全部端口组, 也可以是部分端口组, 因此, 预 置的端口信息可以是全部端口组,也可以是部分端口组。其中部分端口组可以 是预先约定的(如端口组 0和端口组 1 )或者由基站 eNB通过高层信令如 RRC 信令或者下行控制信息通知。 以上多个端口组得到 RSRP, 可以对各个端口组 得到的 RSRP进行平滑或者滤波等处理从而进一步提高了 RSRP测量的精度, 同时避免 UE逐端口计算从而降低实现复杂性。 此外端口组的配置, 可以保证 基站 eNB能够自适应多种天线配置和天线阵列。
同样的, 采用类似的方法, 基于参考信号资源配置信息中的参考信号端口 配置信息, 以及参考信号配置或者子帧配置, 接收基站发送的参考信号, UE 还可以进一步得到一个或者多个端口组的参考信号接收质量 ( RSRQ , Reference signal Received Quality )或者参考信号强度指示( RSSI )等信号质量 测量信息。其中, RSSI是接收的宽带总功率包括干扰和热噪声, RSRQ为 RSRP 与 RSSI的比。
进一步地, 所述用于通信质量测量的方法, 还可以包括:

具体地,如步骤 103所述方法, 可以获得一个或者多个端口组中的参考信 号接收功率,例如可以得到端口组 0, 1 , 2 ,和 3对应的参考信号接收功率 w^ g, g = 0,1, 2,3。
所述路径损耗估计可以基于一个端口组的参考信号接收功率和对应的参 考信号功率得到:
PL (g) = 端口组 g的参考信号功率- 高层滤波的端口组 g的 RSRP 其中 ^(g)表示基于端口组 g得到的 PL估计, 其中高层滤波器参数由高 层信令通知。 可以利用其中一个端口组的 PL得到, 例如端口组 0; 所述高层 滤波的端口组 g 的 RSRP利用高层信令通知的高层滤波器参数对端口组 g 的 RSRP进行滤波得到。
以上所述用于得到 PL估计的端口组可以是预定义的 (如端口组 0 )或者 由基站 eNB通过高层信令如 RRC信令或者下行控制信息通知。 以上基于一个 端口组得到 PL估计, 可以降低 UE PL估计的实现复杂性, 同时, 保证 PL估 计的一致性。 同时端口组的配置, 可以保证基站 eNB能够自适应多种天线配 置和天线阵列。
所述路径损耗估计也可以基于多个端口组的参考信号接收功率和对应的 参考信号功率得到。 具体地, 所述 PL估计可以是多个端口组得到 PL估计的 线性平均。
