实施例一
本实施例提供了一种无线资源管理的测量方法, 在介绍本实施例提供 的方法之前, 首先参见图 1所示的 HetNet场景下的网络部署示意图。 图 1中, 如果 Macro (宏小区)覆盖范围内部署了多个 RRH, 并且这些 RRH与 Macro 使用相同的载波频率以及 PCI ( Physical Cell Identifier, 物理小区标识), 则
如果 UE沿用现有 CRS的测量机制进行上报, 网络侧将无法区分各 RRH节点 下接入链路的信道质量。 对此, 本实施例提供的方法釆取了基于 CSI-RS ( Channel State Information Reference Signal, 信道状态信息参考信号 )实现 RRM的测量, 参见图 2, 本实施例提供的方法流程具体如下:
201 : 网络侧设备确定 UE进行测量使用的测量配置信息,该测量配置信 息包括以下之一或组合: CSI-RS的天线端口、 资源配置、 子帧配置、 物理 小区标识、 功率信息、 载波标识和 CSI-RS加 ·ί尤标识;
202: 将测量配置信息和 /或测量配置信息对应的标识发送给 UE, 使 UE 才艮据测量配置信息和 /或测量配置信息对应的标识进行相应的测量。
其中, 将测量配置信息和 /或测量配置信息对应的标识发送给 UE, 具体 包括:
在测量配置中建立新的测量对象, 新的测量对象中包含测量配置信息 和 /或测量配置信息对应的标识, 并将测量配置发送给 UE。
可选地, 将测量配置信息和 /或测量配置信息对应的标识发送给 UE, 具 体包括:
在测量配置中的原有测量对象中增加测量配置信息和 /或测量配置信息 对应的标识, 并将测量配置发送给 UE。
进一步地, 将测量配置信息对应的标识发送给 UE之前, 还包括: 网络侧设备和 UE各自存储测量配置信息与测量配置信息对应的标识; 将测量配置信息和 /或测量配置信息对应的标识发送给 UE , 使 UE根据 测量配置信息和 /或测量配置信息对应的标识进行相应的测量, 具体包括: 将测量配置信息对应的标识发送给 UE后, UE根据测量配置信息对应的 标识获取对应的测量配置信息, 并根据获取到的测量配置信息进行参考信 号接收功率 RSRP和 /或参考信号接收质量 RSRQ的测量。
可选地,将测量配置信息对应的标识发送给用户设备 UE之前,还包括: 通过***广播消息或 RRC消息将测量配置信息和测量配置信息对应的 标识发送给 UE;
将测量配置信息和 /或测量配置信息对应的标识发送给 UE , 使 UE根据 测量配置信息和 /或测量配置信息对应的标识进行相应的测量, 具体包括: 将测量配置信息对应的标识发送给 UE后, UE根据测量配置信息对应的 标识获取对应的测量配置信息, 并根据获取到的测量配置信息进行参考信
号接收功率 RSRP和 /或参考信号接收质量 RSRQ的测量。
进一步地,当测量配置信息包括本小区和 /或邻小区的测量配置信息时, 网络侧设备确定 UE进行测量使用的邻小区的测量配置信息之前, 还包 括:
通过 X2接口获取邻小区使用的测量配置信息。
进一步地, 测量配置信息中还包括 PCI参数和 /或偏置参数; 或者, 测量 配置信息还可以与 PCI参数和 /或偏置参数进行——对应。
进一步地,将测量配置信息和 /或测量配置信息对应的标识发送给 UE之 后, 还包括:
接收 UE上报的测量配置信息和对应的测量结果;
或者, 接收 UE上报的测量配置信息对应的标识和对应的测量结果。 具体地, 将测量配置信息发送给 UE之后, 接收 UE上报的测量配置信息 对应的标识和对应的测量结果, 具体包括:
接收 UE根据测量配置信息进行参考信号接收功率 RSRP和 /或参考信号 接收质量 RSRQ的测量, 并获取测量配置信息对应的标识后上报的测量配置 信息对应的标识和对应的测量结果。
本实施例提供的方法,通过引入基于 CSI-RS的 RRM的测量,即使 Macro 和 RRH的载波频率和 PCI都相同, 对 UE而言认为是同一个小区, 但 Macro和 RRH使用不同的 CSI-RS配置, 则 UE根据 CSI-RS的配置进行测量和上报, 从 而网络侧设备可以获取各网络节点与 UE间的信道质量,从而决定 UE的附属 节点选择或网络侧节点的协调发送。
为了更加详细的阐述本实施例提供的方法, 下面, 结合上述内容, 通 过下面的实施例二至实施例五的内容, 对本实施例提供的方法进行具体描 述, 详见如下实施例二至实施例五: 实施例二
本实施例提供了一种无线资源管理的测量方法, 结合上述实施例一的 量配置信息为例, 对本实施例提供的无线资源管理的测量方法进行举例说 明。 参见图 3 , 本实施例提供的方法流程具体如下:
301 : eNB在测量配置中建立新的测量对象, 该新的测量对象中包含测
量配置信息;
针对该步骤,基于 CSI-RS的 RRM测量和上报, 即 UE可以对多个 CSI-RS 的配置进行测量和上报, 测量配置信息可以包括以下之一或组合: CSI-RS 的天线端口、 资源配置、 子帧配置、 物理小区标识、 功率信息、 载波标识 和 CSI-RS加扰 ID。 其中, 一个载波标识可以对应一种载波频率。
本实施例不对具体的测量配置进行限定,具体实现时,可釆用基于 CRS 的 RRM测量时所釆用的测量配置, 并在测量配置中为基于 CSI-RS的 RRM测 量定义一个新的测量对象, 例如: MeasObjectEUTRA-CSI-RS IE, 该 IE与现 有机制中基于 CRS的 RRM测量对象(例如: MeasObjectEUTRA等)相互独 立。 该新的测量对象的配置可如下所示:
MeasObjectToAddMod:: = SEQUENCE {
measObj ectldMeasObj ectld,
measObject CHOICE {
measObjectEUTRA MeasObjectEUTRA,
measObjectUTRA MeasObj ectUTRA,
measObjectGERAN MeasObj ectGERAN,
measObjectCDMA2000 MeasObjectCDMA200, measObj ectEUTRA-csi-rs MeasObj ectEUTRA-CSI-RS //CSI-RS的测量对象定义
进一步地, 在测量配置中新定义的测量对象, 至少需要包含以下信息:
1、 测量对象对应的载波频率
2、 测量带宽
3、 频率偏置
4、 CSI-RS的配置信息
即: MeasObjectEUTRA-CSI-RS:: = SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
offsetFreq Q-offsetRange DEFAULT dBO,
csi-rsConfigList SEQUENCE(SIZE(1..maxCSI-RS))
CSI-RSConfig
其中, carrierFreq 为载波频率, allowedMeasBandwidth 为测量带宽, offsetFreq 为频率偏置, csi-rsConfigList 为 CSI-RS的测量配置信息, CSI-RSConfig IE至少需要包含以下一种或多种元素:
1、 CSI-RS传输的天线端口配置
2、 CSI-RS传输的资源配置
3、 CSI-RS传输的子帧配置
即: CSI-RSConfig ::= SEQUENCE {
csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8}, resourceConfig NTEGER (0..31),
subframeConfig INTEGER (0..154),
可选地, 除了釆用上述建立新的测量对象的方式通知 UE测量配置信息 的方式外, 还可以在测量配置中的原有测量对象中增加 CSI-RS的测量配置 信息的方式, 针对该种方式, 测量对象如下所示:
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,
presenceAnteenaPortl PresenceAntennaPortl ,
[[measCycleSCell-rlO MeasCycleSCell-rlO OPTIONAL -Need ON
measSubframePatternConfigNeigh-rlO
MeasSubframePatternConfigNeigh-rlO OPTIONAL -Need ON
]]
csi-rsConfigList SEQUENCE(SIZE(1..maxCSI-RS)) OF CSI-RSConfig OPTIONAL
其中, CSI-RSConfig lE的定义可参见上述内容, 此处不再赘述。
302: eNB将包含新的测量对象的测量配置发送给 UE;
针对该步骤,本实施例不对 eNB发送测量配置的方式进行限定,可参考 现有基于 CRS的 RRM测量中所釆用的发送方式。
303: UE接收测量配置, 根据该测量配置获取测量配置信息, 并根据测 量配置信息进行相应的测量;
其中, 本实施例不对 UE接收测量配置的方式进行限定, 可参考现有基 于 CRS的 RRM测量中所釆用的接收方式。 另外, 由于 eNB在测量配置中建 立了新的测量对象, 而该新的测量对象中包含测量配置信息, 因此, UE在 接收到测量配置后, 通过解析该测量配置即可获取测量配置信息, 从而根 据获取到的测量配置信息进行 RRM测量。对于 UE根据获取到的测量配置信 息进行 RRM测量的方式, 本实施例同样不作具体限定。
至此, 基于 CSI-RS的 RRM测量流程结束, 为了使 eNB能够获知各网络 节点与 UE间的信道质量,从而决定 UE的附属节点选择或网络侧节点的协调 发送, UE在进行 RRM测量之后, 本实施例提供的方法还可以包括后续上报 测量结果的过程, 详见如下步骤 304。
304: UE向 eNB上报测量配置信息和对应的测量结果。
针对该步骤, UE向 eNB上报测量结果时, 为了使 eNB明确 UE上报的测 量结果是对应哪种测量配置信息, 则 UE在上报测量结果时, 还需要上报测 量结果对应的测量配置信息。
另外, 为了降低 UE上报测量结果时占用的资源, 作为优选方案, 本实 施例提供的方法还支持以测量配置信息对应的标识来替代上报测量配置信 息的方式, 即 UE向 eNB上报测量配置信息对应的标识及对应的测量结果。 针对该种上报方式, 由于 eNB仅向 UE下发了测量配置信息, 而测量配置信 息对应的标识, 即 CSI-RS ID不需要 eNB的配置或发送, 此时 CSI-RS ID可以 是 eNB和 UE约定的一个规则产生的, 则 UE根据 eNB发送的测量配置信息进 行相应的测量之后, UE根据该测量配置信息获取 CSI-RS ID, 之后再向 eNB 上报 CSI-RS ID和对应的测量结果。 例如, CSI-RS ID是 eNB下发的所有 CSI-RS配置的索引, 或者, 是 UE按照 eNB下发的 CSI-RS配置的顺序, 将它 们进行标识-即赋值 ID (比如共有 32个, 按照 ID从 0 ~ 31进行编号), 然后
UE在上报时, 如果约定上报 8个, 在上报的 8个中携带其 CSI-RS ID。
为了使 UE能够以 CSI-RS ID替代测量配置信息进行上报,除了釆用上述 方式由 eNB和 UE预先约定 CSI-RS ID之外, 本实施例提供的方法还支持其他 方式, 例如, eNB在向 UE发送测量配置信息之前, 还可以先通过***广播 消息或 RRC消息向 UE发送测量配置信息与测量配置信息对应的标识,则 UE 根据 eNB发送的测量配置信息进行测量之后,从***广播消息或 RRC消息中 获取测量配置信息对应的标识, 之后再上报测量配置信息对应的标识和对 应的测量结果。
无论 UE釆用上述哪种方式获取测量配置信息对应的标识, 在上报测量 配置信息对应的标识和对应的测量结果时, 均可进行 CSI-RS测量结果的上 报。 且如果 UE需要上报基于 CSI-RS的测量结果, 可以在现有测量上报消息 中新定义 MeasResultList-CSI-RS IE。
MeasResults:: = SEQUENCE {
measld Measld,
measResultPCell SEQUENCE {
rsrpResult RSRP-Range,
rsrqResult RSRQ-Range, measResultNeighCells CHOICE {
measResultListEUTRA MeasResultListEUTRA,

[[locationlnfo-rlO Locationlnfo-rlO OPTIONAL, measResultServFreqList-r 10 MeasResultServFreqList-r 10 OPTIONAL,
]]
measResultList-csi-rs MeasResultList-CSI-RS OPTIONAL 其中, MeasResultList-CSI-RS IE用于上报 measld对应频率上使用的所有
CSI-RS测量结果, 具体定义如下:
MeasResultList-CSI-RS::=SEQUENCE(SIZE(l ... maxCSI-RSReport))OF MeasResult-CSI-RS
MeasResult-CSI-RS:: = SEQUENCE {
csi-rsld CSI-RSId,
rsrpResult RSRP-Range,
rsrqResult RSRQ-Range 可选地, 除了釆用上述在现有测量上报消息的基础上增加对 CSI-RS测 量结果的上报的方式外, 还可以定义新的测量上报消息的方法来上报 CSI-RS测量结果, 针对该种方式, 新定义的测量上报消息如下所示:
MeasurementReport-CSI-RS ::= SEQUENCE {
measurementReport-csi-rs MeasurementResults-CSI-RS, nonCriticalExtension SEQUENCE {} OPTIONAL }
MeasurementResults-CSI-RS :: = SEQUENCE {
measld Measld,
measResultList-csi-rs MeasResultList-CSI-RS 其中, MeasResultList-CSI-RS IE的定义同上, 这里不再累赘。 从上面 可以看出, 不同的频率对应不同的 measld。 也就是说, 不同频率上的所有 CSI-RS 测 量 结 果可 以 通 过 不 同 的 MeasResults或 者 不 同 的 MeasurementReport-CSI-RS消息来上报,上报的 CSI-RS测量结果与 Cell无关, 仅与频率对应。 同理, 上报的 CSI-RS测量结果也可以与 Cell相关, 这里不再 累赘。
以上论述了 CSI-RS的测量配置信息与 Cell (小区)相互独立的情况下的 RRM测量流程, 针对 CSI-RS的测量配置信息与 Cell相关联的情况, CSI-RS 的测量配置信息需要与 PCI ( Physical Cell Identifier, 物理小区标识 )进行绑 定, 例如: 在上述 CSI-RSConfig lE定义中增加 PCI参数, 如下所示:
即: CSI-RSConfig ::= SEQUENCE {
csi-rsld INTEGER(1..maxCSI-RS),
physicalcellld PhysCellld OPTIONAL, csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8} resourceConfig BIT STRING NTEGER (0..31),
subframeConfig INTEGER (0..154),
除此之外, 现有的基于 CRS的 RRM测量中, 网络侧可以给不同测量小 区配置不同的偏置参数, 以便 UE可以优先切换到这些指定小区中。 本实施 例提供的方法在引入 CSI-RS之后, 针对频率相同, PCI相同 /不同的节点, 也可以根据 CSI-RS的配置来进行 CSI-RS配置或端口( port )或节点的优先选 择, 例如: 通过 IndividualOffset的设定。
具体实现时, 网络侧需要给不同节点设置不同的偏置参数, 也就是说, 在测量配置中, 可将 IndividualOffset参数与 CSI-RS ID参数进行绑定, 例如: CSI-RSConfig IE定义中增加 IndividualOffset参数, 如下所示:
即: CSI-RSConfig ::= SEQUENCE {
csi-rsld INTEGER(1..maxCSI-RS),
csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8}, resourceConfig BIT STRING NTEGER (0..31),
subframeConfig INTEGER (0..154),
IndividualOffset Q-OffsetRange OPTIONAL
另外, 本实施例及后续实施例所涉及到的 RRM测量均包括但不限于 RSRQ ( Reference Signal Received Quality, 参考信号接收质量)测量和 /或 RSRP ( Reference Signal Received Power, 参考信号接收功率) 测量。 本实 施例及后续实施例所涉及到的测量配置信息, 该测量配置信息中除了包含 本小区内使用的 CSI-RS配置信息外, 还可以包含部小区内使用的 CSI-RS配 置信息, 因此, 网络侧设备在确定测量配置信息时, 需要通过 X2接口获取 邻小区的测量配置信息。 具体实现时, 可以在 X2接口上通过 ENB CONFIGURATION UPDATE消息来获取邻小区内使用的 CSI-RS配置信息, 也就是说, 需要在 ENB CONFIGURATION UPDATE消息中新定义 IE , 用于
传输 CSI-RS的配置信息, 其中还可以包含零功率传输的 CSI-RS配置信息。 如下所示:。
>zeroTxPowerSubframeConfig O
(0..154)
其中, maxnoofCSI-RS IE的定义如下:
本实施例提供的方法,通过引入基于 CSI-RS的 RRM的测量,即使 Macro 和 RRH的载波频率和 PCI都相同, 对 UE而言认为是同一个小区, 但 Macro和 RRH使用不同的 CSI-RS配置, 则 UE根据 CSI-RS的配置进行测量和上报, 从 而网络侧设备可以获取各网络节点与 UE间的信道质量,从而决定 UE的附属 节点选择或网络侧节点的协调发送。 实施例三
本实施例提供了一种无线资源管理的测量方法, 结合上述实施例一的 内容, 为了便于说明, 本实施例以 UE均未预先获取或未预先存储测量配置 信息, eNB通过向 UE发送***广播消息将测量配置信息和测量配置信息对 应的标识通知给 UE为例, 对本实施例提供的无线资源管理的测量方法进行 举例说明。 参见图 4, 本实施例提供的方法流程具体如下:
401 : eNB通过***广播消息将测量配置信息和测量配置信息对应的标 识发送给 UE;
针对该步骤,基于 CSI-RS的 RRM测量和上报, 即 UE可以对多个 CSI-RS 的配置进行测量和上报, 测量配置信息可以包括以下之一或组合: CSI-RS
的天线端口、 资源配置、 子帧配置、 物理小区标识、 功率信息、 载波标识 和 CSI-RS加扰 ID。 其中, 一个载波标识可以对应一种载波频率, 为了使 UE 在上报测量结果时, 无需再上报测量配置信息, 从而节省资源, 本实施例 提供的方法, 釆取了对 CSI-RS测量配置信息的元素以一定顺序进行组合得 到 CSI-RS的配置索引, 即测量配置信息对应的标识 CSI-RS ID的方式。 每个 CSI-RS ID对应着一种 CSI-RS的测量配置信息, 即对应着 CSI-RS配置元素的 一种组合。
在确定 CSI-RS ID时, 一种优选方式是 CSI-RS的测量配置信息仅包含天 线端口数(AP ), 资源配置 (RC)和子帧配置 (SC)三个元素。 针对这三种元素 可以有如下几种情况:
Case 1 : 天线端口数 AP, 资源配置 RC, 子帧配置 SC;
Case 2: 固定 AP, 不同 CSI-RS的配置只是 RC和 SC不同;
Case 3: 固定 SC, 不同 CSI-RS的配置只是 AP和 RC不同;
Case 4: 固定 AP和 SC, 不同 CSI-RS的配置只是 RC不同。
针对每种情况,可以定义 CSI-RS ID的最大值 maxCSI-RS。下面以 case 4, 且 FDD为例进行说明。 天线端口数 AP固定, 例如: 2天线端口, 测量子帧周 期 SC固定 (例如: 10ms ), 在正常 CP (循环前缀) 场景下, maxCSI-RS的 取值为 32*10=320, 如下面表 1所示:
表 1
在确定每个测量配置信息对应的测量配置信息对应的标识, 即 CSI-RS
ID之后, 服务小区中的 eNB可以通过***广播消息, 将本小区和 /或邻小区 内使用的 CSI-RS配置信息使用的 CSI-RS测量配置信息告之 UE, 例如: 通过 ***广播消息中的第二 SIB ( System Information Block, ***信息块 )消息, 即 SIB2消息。
即 SystemInformationBlockType2:: = SEQUENCE lateNonCriticalExtension OCTET STRING OPTIONAL,

[[ac-BarringForCSFB-rlO AC-BarringConfig
OPTIONAL, -Need OP
]]
csi-rsConfigList SEQUENCE(SIZE(1..maxCSI-RS)) OF CSI-RSConfig OPTIONAL
}
其中, CSI-RSConfig IE需要包含以下一种或多种元素:
1、 CSI-RS配置索引
2、 CSI-RS传输的天线端口配置
3、 CSI-RS传输的资源配置
4、 CSI-RS传输的子帧配置
即: CSI-RSConfig ::= SEQUENCE {
csi-rsld INTEGER(1..maxCSI-RS),
csi-rsAntennaPortsCount ENUMERATED {anl, an2, an4, an8}, resourceConfig INTEGER (0..31),
subframeConfig INTEGER (0..154),
csi-rsld 为 CSI-RS配置索引, 即测量配置信息对应的标识。
402: UE接收***广播消息,并根据该***广播消息获取测量配置信息 和测量配置信息对应的标识;
针对该步骤, 本实施例不对 UE接收***广播消息的方式进行限定, 由
于该***广播消息中包含测量配置信息和测量配置信息对应的标识, 则 UE 接收到***广播消息后, 即可根据该***广播消息获取测量配置信息和测 量配置信息对应的标识。
403: eNB在测量配置中的原有测量对象中增加测量配置信息对应的标 识, 并将该测量配置发送给 UE;
针对该步骤, 由于 UE已经通过***广播消息获知测量配置信息, 因此, 当 eNB对 UE进行 CSI-RS RRM测量配置时,仅需要指定测量配置信息对应的 标识即可。 UE4艮据该测量配置信息对应的标识获取对应的测量配置信息, 从而进行相应的 CSI-RS测量。 在向 UE下发测量配置信息对应的标识时, 本 实施例釆取了在测量配置的原有测量对象中增加测量配置信息对应的标 识, 并将该测量配置发送给 UE的方式, 则原有测量对象在增加测量配置信 息对应的标识之后, 如下所示:
MeasObjectEUTRA ::= SEQUENCE {
carrierFreq ARFCN-ValueEUTRA,
allowedMeasBandwidth AllowedMeasBandwidth,

[[measCycleSCell-rlO MeasCycleSCell-rlO OPTIONAL,

measSubframePatternConfigNeigh-rlO
MeasSubframePatternConfigNeigh-rlO OPTIONAL -Need ON
]]
csi-rsIdList BIT STRING (SIZE(maxCSI-RS)) OPTIONAL 其中, csi-rsIdList lE是 CSI-RS配置对应的测量配置信息对应的标识,釆 用 bitmap形式表示。 即: 如果某 bit置为 0, 则说明网络侧要求 UE对该索引值 对应的 CSI-RS配置进行 RRM测量; 否则, 说明 UE不需要对该索引值对应的 CSI-RS配置进行 RRM测量。
可选地, 除了通过在测量配置中的原有测量对象中增加测量配置信息 对应的标识, 以将其通知给 UE外, 本实施例提供的方法还支持在测量配置 中建立新的测量对象, 该新的测量对象中包含测量配置信息对应的标识。
同现有基于 CRS的 RRM测量方式一样, 一个测量对象对应一个载波频率。 引入 CSI-RS测量后, 该载波频率上可能存在多个 CSI-RS的测量配置信息, 不同的 CSI-RS测量配置信息与一个配置索引值相对应。根据上述步骤 401的 描述,由于 eNB已经通过***广播消息将测量配置信息和测量配置信息对应 的标识发送给 UE, 则 eNB仅需要通知 UE该 CSI-RS ID参数即可, 则新的测 量对象, 至少需要包含以下信息:
1、 测量对象对应的载波频率
2、 测量带宽
3、 频率偏置
4、 CSI-RS的配置索引列表
即: MeasObjectEUTRA-CSI-RS:: = SEQUENCE {

404: UE根据测量配置中的测量配置信息对应的标识获取***广播消息 中的测量配置信息, 并根据获取到的测量配置信息进行相应的测量;
具体地, 由于测量配置的原有测量对象中增加了测量配置信息对应的 标识, 则 UE 居该测量配置可获取测量配置信息对应的标识, 又由于*** 广播消息中增加了测量配置信息和测量配置信息对应的标识, 因此, UE根 据测量配置中的测量配置信息对应的标识即可获取到对应的测量配置信 息,从而根据获取到的测量配置信息进行 RRM测量。 关于 UE进行 RRM测量 的方式, 本实施例不作具体限定。
405: UE向 eNB上报测量配置信息对应的标识和对应的测量结果。 针对该步骤, 由于 UE和 eNB均已经明确测量配置信息和测量配置信息 标识的对应关系, 为了使 eNB明确 UE上报的测量结果是根据何种测量配置 信息进行测量得到, 因此, UE向 eNB上报测量结果时, 还需要上报测量结 果对应的测量配置信息对应的标识。 本实施例不对 UE向 eNB上·¾测量配置 信息对应的标识和 RRM测量的测量结果的方式进行限定, 实际应用中, 可
在现有测量上报消息的基础上增加对 CSI-RS测量结果的上报, 或者, 新定 义一个基于 CSI-RS的测量上报消息 MeasResults-CSI-RS,具体方案可参见实 施二中的对应描述, 这里不再累赘。
以上论述了 CSI-RS的测量配置信息与 Cell (小区)相互独立的情况下的 RRM测量流程, 针对 CSI-RS的测量配置信息与 Cell相关联的情况, 需要将 CSI-RS的测量配置信息与 PCI ( Physical Cell Identifier, 物理小区标识)进 行绑定,具体绑定方式详见上述实施例二中步骤 304的描述,此处不再赘述。
除此之外, 现有的基于 CRS的 RRM测量中, 网络侧可以给不同测量小 区配置不同的偏置参数, 以便 UE可以优先切换到这些指定小区中。 本实施 例提供的方法在引入 CSI-RS之后, 针对频率相同, PCI相同 /不同的节点, 也可以根据 CSI-RS的配置来进行 CSI-RS配置或端口( port )或节点优先选择, 具体可参见上述实施例二中步骤 304的描述, 此处不再赘述。
本实施例提供的方法,通过引入基于 CSI-RS的 RRM的测量,即使 Macro 和 RRH的载波频率和 PCI都相同, 对 UE而言认为是同一个小区, 但 Macro和 RRH使用不同的 CSI-RS配置, 则 UE根据 CSI-RS的配置进行测量和上报, 从 而网络侧设备可以获取各网络节点与 UE间的信道质量,从而决定 UE的附属 节点选择或网络侧节点的协调发送。 实施例四
