  • Wideband Code Division Multiple Access is a widely used wireless communication technology, and is responsible for the 3rd Generation Partnership Project (3rd Generation Partnership Project). Formulated and in continuous evolution. In the Rel-5 version and subsequent versions of the WCDMA protocol, high-speed data access (High Speed Packet Access) is introduced to support higher data traffic. HSPA is currently evolving toward HSPA+ and other key technologies, including higher-order multiple input multiple output (MIMO) technology and more carrier aggregation.

  • CSI Cell Status Information
  • more S-CPICH channels may be supported for CSI estimation; and scheduled non-precoded pilots may also be scheduled (also called scheduling pilots or demodulation commons). Pilot) is used as data demodulation.
  • Scheduling non-precoded pilots is only transmitted during data transmission, since scheduling non-precoded pilots tends to be higher than the common pilot power transmitted on antennas 3 and 4, thereby facilitating user equipment (User Equipment, For the "UE", the scheduling of non-precoded pilots is used for more accurate channel estimation to facilitate better data demodulation performance.
  • scheduling non-precoded pilots does not improve the performance of the 4-MIMO MIMO UE.
  • scheduling non-pre-coded pilots may not be transmitted, thereby reducing interference to other UEs, especially terminals that do not support 4-OFDM, due to scheduling non-pre-coded pilots to it. They are pure interference.
  • scheduling non-precoded pilots can improve the performance of 4 MIMO terminals.
  • the non-precoded pilot can be shared by the High Speed Downlink Shared Channel (HS-DSCH) shared control channel (Shared Control Channel for HS-DSCH, the tube is called "HS" -SCCH" Signaling is activated or deactivated. If the network is based on a certain condition, for example, the signal-to-noise ratio of the 4-band MIMO UE is low, and the scheduling non-pre-coded pilot may not be sent, the scheduling non-pre-coded pilot may be deactivated by the HS-SCCH signaling; otherwise, Scheduling non-precoded pilots can be activated by HS-SCCH signaling.

  • the UE when the cell is configured with downlink MIMO, the UE does not initially know whether the scheduled non-precoded pilot is activated or deactivated. The UE knows whether the scheduling non-precoded pilot is activated or deactivated, which is beneficial for the UE to accurately utilize the information of scheduling non-precoded pilots, and improve the accuracy of four MIMO data detection. Since scheduling non-precoded pilots is determined by the base station and is typically a small cell level parameter, it can be determined by the situation of multiple UEs. Therefore, when the UE is configured as a downlink MIMO state by the Radio Network Controller ("Radio Network Controller"), it is possible to schedule whether the non-precoded pilot is activated or deactivated.
  • Radio Network Controller Radio Network Controller
  • the UE cannot determine whether the scheduled non-precoded pilot is active or deactivated based on the actual state of the base station.
  • the base station needs to send HS-SCCH signaling to notify the UE to schedule the activation or deactivation of non-precoded pilots almost every time the UE configures downlink 4 MIMO. Therefore, a lot of HS-SCCH signaling is required to complete this function, and the physical layer dynamic signaling overhead is added.
  • the base station since the base station sends the HS-SCCH signaling, it needs to wait for the UE to send an acknowledgment (Acknowledgment, the tube is called "ACK"). After scheduling data for 4 MIMO UEs, it also brings delay in scheduling. Summary of the invention

Description

指示导频状态的方法和设备 技术领域
本发明涉及通信领域， 并且更具体地， 涉及指示导频状态的方法、 无线 网络控制器、 基站、 用户设备和系统。 背景技术
宽带码分多址 ( Wideband Code Division Multiple Access , 筒称为 "WCDMA" ) 为目前广泛使用的无线通信技术， 由第三代移动通信伙伴计划 ( 3rd Generation Partnership Project, 筒称为 "3GPP" )负责制定， 并处于持续 演进中。 在 WCDMA协议 Rel-5版本及后续版本中， 引入了高速数据接入 ( High Speed Packet Access , 筒称为 "HSPA" )技术， 用以支持更高的数据业 务传输。 目前 HSPA正在向 HSPA+等方向演进， 包含支持更高阶的多输入多 输出 （ Multiple Input Multiple Output, 筒称为 "MIMO" )技术， 以及更多载波 聚合等关键技术。
下行 4天线 MIMO在 3GPP无线接入网络（ Radio Access Network, 筒 称为" RAN" ) #53次会议讨论立项， 旨在进一步提高小区吞吐量。 在已经支 持的下行 2 发 MIMO 系统中， 主公共导频信道 ( Primary Common Pilot Channel, 筒称为 "P-CPICH" )和辅公共导频信道 ( Secondary Common Pilot Channel , 筒称为 "S-CPICH" ) 用来支持信道状态信息 （ Channel Status Information, 筒称为 "CSI" )估计和数据解调。 而在下行 4发 MIMO中， 可 能支持更多的 S-CPICH信道， 用来做 CSI估计； 并支持调度非预编码导频 ( Scheduled non-precoded pilot, 也可称为调度导频或解调公共导频）用作数 据解调。 调度非预编码导频仅在数据传输的时候发送， 由于调度非预编码导 频往往比天线 3和天线 4上发送的公共导频功率更高，从而有助于用户设备 ( User Equipment, 筒称为" UE" )利用调度非预编码导频进行更加准确的信 道估计， 以利于得到更好的数据解调性能。
在某些条件下，如 UE的信干噪比（ Signal to Interference plus Noise Ratio, 筒称为 "SINR" )较低的场景， 调度非预编码导频对 4发 MIMO UE性能提升 不大， 因此可以在这种情况下不发送调度非预编码导频， 从而降低对其它 UE的干扰， 尤其是不支持 4发 MIMO的终端， 由于调度非预编码导频对它 们是纯干扰， 这种情况下不发调度非预编码导频就能在一定程度上提高不支 持 4发 MIMO终端的性能。
3GPP 达成一致， 调度非预编码导频可通过高速下行共享信道（High Speed Downlink Shared Channel,筒称为 "HS-DSCH" )的共享控制信道（ Shared Control Channel for HS-DSCH, 筒称为 "HS-SCCH" )信令激活或去激活。 如 果网络基于某种条件， 如 4发 MIMO UE的信噪比较低， 判定调度非预编码 导频可以不发， 则可通过 HS-SCCH信令去激活调度非预编码导频； 反之， 则可以通过 HS-SCCH信令激活调度非预编码导频。
目前当小区配置下行 4发 MIMO时， UE初始不知道调度非预编码导频 是激活还是去激活。 UE获知调度非预编码导频是激活还是去激活状态， 有 利于 UE准确的利用调度非预编码导频存在的信息，提高 4发 MIMO数据检 测的精度。 由于调度非预编码导频是否激活由基站决定， 并且是个典型地小 区级参数， 可由多个 UE的情况来确定。 因此 UE被无线网络控制器（Radio Network Controller, 筒称为 "RNC" )配置为下行 MIMO状态时， 调度非预编 码导频是激活还是去激活皆有可能。
UE无法根据基站的实际状态判定调度非预编码导频是激活还是去激活 状态。 基站几乎每次在 UE配置下行 4发 MIMO时， 都需要发送 HS-SCCH 信令来通知 UE调度非预编码导频的激活或去激活状态。 因此， 需要很多 HS-SCCH信令来完成这个功能， 增加了物理层动态信令的开销； 而且， 由 于基站发送 HS-SCCH信令后需要等待 UE发送确认（Acknowledgment, 筒 称为" ACK" )后才能给 4发 MIMO UE调度数据， 也带来调度上的时延。 发明内容

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， 所描述的实施例是本发明的一部分实施例， 而不 是全部实施例。 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 造性劳动的前提下所获得的所有其他实施例， 都应属于本发明保护的范围。
应理解， 本发明实施例的技术方案可以应用于各种通信系统， 例如： 全 球移动通讯（ Global System of Mobile communication , 筒称为 "GSM" )系统、 码分多址（Code Division Multiple Access, 筒称为 "CDMA" ) 系统、 宽带码 分多址（ Wideband Code Division Multiple Access , 筒称为 "WCDMA" )系统、 通用分组无线业务（General Packet Radio Service, 筒称为 "GPRS" )、 长期演 进（Long Term Evolution, 筒称为 "LTE" ) 系统、 LTE频分双工 （Frequency Division Duplex,筒称为" FDD" )系统、 LTE 时分双工（ Time Division Duplex, 筒称为 "TDD" )、 通用移动通信系统 ( Universal Mobile Telecommunication System, 筒称为 "UMTS" ),全球互联微波接入（ Worldwide Interoperability for Microwave Access , 筒称为 "WiMAX" )通信系统等。
还应理解，在本发明实施例中，用户设备（ User Equipment,筒称为 "UE" ) 可称之为终端 ( Terminal ), 移动台 ( Mobile Station, 筒称为 "MS" )、 移动终 端 （Mobile Terminal ) 等， 该用户设备可以经无线接入网 （Radio Access Network, 筒称为 "RAN" ) 与一个或多个核心网进行通信， 例如， 用户设备 可以是移动电话（或称为"蜂窝"电话）、 具有移动终端的计算机等， 例如， 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动 装置， 它们与无线接入网交换语音和 /或数据。 在本发明实施例中， 基站可以是 GSM 或 CDMA 中的基站 （Base Transceiver Station , 筒称为 "BTS" ), 也可以是 WCDMA中的基站（ NodeB , 筒称为 "NB" ), 还可以是 LTE中的演进型基站（Evolutional Node B, 筒称为 'ΈΝΒ或 e-NodeB" ), 本发明并不限定。 但为描述方便， 下述实施例将以基 站 NodeB和用户设备 UE为例进行说明。
在本发明实施例中，调度非预编码导频也称为调度导频、解调公共导频， 为描述方便， 下述实施例以调度非预编码导频为例进行说明。
图 1示出了根据本发明实施例的指示导频状态的方法 100的示意性流程 图。 如图 1所示， 该方法 100包括：
S110, 无线网络控制器 RNC接收基站发送的调度非预编码导频状态信 息， 该调度非预编码导频状态信息指示调度非预编码导频的激活状态或去激 活状态；
S120, 该 RNC向用户设备 UE发送 4发多输入多输出 MIMO模式配置 信令， 该配置信令携带该调度非预编码导频状态信息， 使得该 UE在配置为 4发 MIMO模式时根据该调度非预编码导频状态信息获取调度非预编码导频 状态。
4发 MIMO模式支持调度非预编码导频用作数据解调。 如图 2所示， 天 线 3和天线 4不但可以发送公共导频， 即 S-CPICH2和 S-CPICH3 , 还可以 发送调度非预编码导频。 由于调度非预编码导频往往比天线 3和天线 4上发 送的公共导频功率更高， 从而有助于 UE利用调度非预编码导频进行更加准 确的信道估计， 得到更好的数据解调性能。 然而， 在信噪比较低的场景， 调 度非预编码导频对 4发 MIMO UE性能提升不大， 因此可以在这种情况下不 发送调度非预编码导频， 以降低对其它 UE的干扰。 基站可以根据小区的情 况决定是否激活调度非预编码导频，这样，调度非预编码导频状态就有两种， 即激活状态和去激活状态。 在本发明实施例中， 为了使 UE在配置为 4发 MIMO模式时获知调度非预编码导频状态， RNC首先接收基站发送的调度 非预编码导频状态信息，该调度非预编码导频状态信息指示调度非预编码导 频的激活状态或去激活状态， 然后， RNC向 UE发送携带该调度非预编码导 频状态信息的 4发 MIMO模式配置信令， 使得该 UE在配置为 4发 MIMO 模式时根据该调度非预编码导频状态信息获取调度非预编码导频状态。 由于 UE在配置为 4发 MIMO模式时就能从该调度非预编码导频状态信息中获取 调度非预编码导频状态， 因此， 基站不需要再发送 HS-SCCH信令通知 UE 调度非预编码导频的激活或去激活状态。
这样， 本发明实施例的指示导频状态的方法， 通过 RNC向 UE发送携 带 RNC从基站接收的调度非预编码导频状态信息的 4发 MIMO模式配置信 令，可以使 UE在配置为 4发 MIMO模式时根据该调度非预编码导频状态信 息获取调度非预编码导频状态， 避免了基站发送 HS-SCCH信令通知 UE调 度非预编码导频状态， 从而能够降低物理层信令开销， 并降低 UE获取 4发 MIMO模式下调度非预编码导频状态的时延。
在 S110中， RNC接收基站发送的调度非预编码导频状态信息。
具体而言， 基站通过 Iub 口信令将调度非预编码导频状态信息发送给
RNC。 例如， 基站通过 Iub口信令中 1个比特或 1个信元表示调度非预编码 导频状态信息， 即利用 Iub口信令中 1个比特或 1个信元指示调度非预编码 导频为激活状态或去激活状态。 RNC通过该 Iub口信令接收到该调度非预编 码导频状态信息。
在 S120中， RNC向 UE发送 4发 MIMO模式配置信令， 该配置信令携 带该调度非预编码导频状态信息。
具体而言， RNC通过无线资源控制 （Radio Resource Control, 筒称为 "RRC" )信令将 UE配置为 4发 MIMO模式， RNC在 RRC信令中携带先前 从基站接收的调度非预编码导频状态信息。 例如， RNC通过 RRC信令中 1 个比特或 1个信元表示该调度非预编码导频状态信息，即利用 RRC信令中 1 个比特或 1 个信元指示调度非预编码导频为激活状态或去激活状态。 由于 RRC信令中携带了调度非预编码导频状态信息， UE可以在 4发 MIMO模式 配置成功的同时，获知调度非预编码导频的激活状态或者去激活状态。这样， 基站可以在 4发 MIMO模式配置成功的同时使用 4发 MIMO调度数据， UE 也可以根据获知的调度非预编码导频的激活状态或去激活状态，相应地使用 或不使用调度非预编码导频解调 4发 MIMO数据， 因此， 降低了调度上的 时延。 并且， 使用 RRC信令来承载调度非预编码导频状态， 也避免了基站 发送物理层信令通知调度非预编码导频的激活状态或去激活状态， 节省了物 理层信令开销。
在本发明实施例中， 如图 3所示， 可选地， S110包括：
S111 , 该 RNC接收该基站在改变调度非预编码导频状态后发送的该调 度非预编码导频状态信息。
具体而言， 调度非预编码导频是否激活由基站决定， 换句话说， 基站根 据小区状况可能会改变调度非预编码导频状态， 即通过 HS-SCCH信令通知 当前已配置 4发 MIMO模式的 UE改变调度非预编码导频状态。基站在改变 的调度非预编码导频状态通知给 RNC, 这样， RNC在为之后的 UE配置 4 发 MIMO时， 就能把当前的调度非预编码导频状态传输给该 UE。
应理解， 若基站一直没有改变调度非预编码导频状态， 则基站一开始确 定的调度非预编码导频状态就是当前的调度非预编码导频状态， 也就是说， 基站一开始发送给 RNC的调度非预编码导频状态信息就指示当前的调度非 预编码导频状态。
本发明实施例的指示导频状态的方法， 通过 RNC向 UE发送携带 RNC 从基站接收的调度非预编码导频状态信息的 4发 MIMO模式配置信令， 可 以使 UE在配置为 4发 MIMO模式时获取调度非预编码导频状态，避免了基 站发送 HS-SCCH信令通知 UE调度非预编码导频状态， 从而能够降低物理 时延。
上文中结合图 1至图 3, 从 RNC的角度详细描述了指示导频状态的方 法， 下面将结合图 4至图 6, 从基站的角度详细描述指示导频状态的方法。
图 4示出了根据本发明另一实施例的指示导频状态的方法 200的示意性 流程图。 如图 4所示， 该方法 200包括：
S210, 基站向无线网络控制器 RNC发送调度非预编码导频状态信息， 该调度非预编码导频状态信息指示调度非预编码导频的激活状态或去激活 状态， 使得该 RNC向第一用户设备 UE发送携带该调度非预编码导频状态 信息的 4发多输入多输出 MIMO模式配置信令， 以使该第一 UE在配置为 4 发 MIMO模式时根据该调度非预编码导频状态信息获取调度非预编码导频 状态。
在本发明实施例中， 第一 UE表示待配置为 4发 MIMO模式的 UE。 为 了使第一 UE在配置为 4发 MIMO模式时获知调度非预编码导频状态，基站 向 RNC发送调度非预编码导频状态信息， 该调度非预编码导频状态信息指 示调度非预编码导频的激活状态或去激活状态， 这样， RNC向第一 UE发送 携带该调度非预编码导频状态信息的 4发 MIMO模式配置信令， 从而使第 一 UE在配置为 4发 MIMO模式时根据该调度非预编码导频状态信息获取调 度非预编码导频状态。 因此，基站不需要再发送 HS-SCCH信令通知第一 UE 调度非预编码导频的激活或去激活状态， 并且， 基站可以在 4发 MIMO模 式配置成功的同时使用 4发 MIMO调度数据，第一 UE也可以根据获知的调 度非预编码导频的激活状态或去激活状态，相应地使用或不使用调度非预编 码导频解调 4发 MIMO数据， 因此， 降低了调度上的时延。
具体而言， 基站将调度非预编码导频状态信息通过 Iub 口信令发送给 RNC。 例如， 基站通过 Iub口信令中 1个比特或 1个信元表示调度非预编码 导频状态信息， 即利用 Iub口信令中 1个比特或 1个信元指示调度非预编码 导频为激活状态或去激活状态。
这样， 本发明实施例的指示导频状态的方法， 通过基站向 RNC发送调 度非预编码导频状态信息， 可以使 RNC向 UE发送携带该调度非预编码导 频状态信息的 4发 MIMO模式配置信令， 以使 UE在配置为 4发 MIMO模 式时根据该调度非预编码导频状态信息获取调度非预编码导频状态，避免了 基站发送 HS-SCCH信令通知 UE调度非预编码导频状态， 从而能够降低物 理层信令开销，并降低 UE获取 4发 MIMO模式下调度非预编码导频状态的 时延。
在本发明实施例中， 如图 5所示， 可选地， 在 S210之前， 该方法 200 还包括：
S220, 该基站通知第二 UE改变调度非预编码导频状态， 其中， 该第二 UE表示已配置为 4发 MIMO模式的 UE。
具体而言， 基站根据小区状况可能会改变调度非预编码导频状态。 基站 在确定改变调度非预编码导频状态时通过 HS-SCCH信令通知第二 UE, 即 已配置为 4发 MIMO模式的 UE, 改变调度非预编码导频状态。 并且， 基站 发送调度非预编码导频状态信息给 RNC, 把最新的调度非预编码导频状态 通知给 RNC, 这样， RNC在为第一 UE配置 4发 MIMO时， 就能把当前的 调度非预编码导频状态传输给该 UE。
在本发明实施例中， 如图 6所示， 可选地， 在 S210之后， 该方法 200 还包括：
S230, 在当前调度非预编码导频状态与该第一 UE根据该调度非预编码 导频状态信息获取的调度非预编码导频状态不一致时， 该基站通知该第一
UE改变调度非预编码导频状态。
具体而言， RNC将第一 UE配为 4发 MIMO模式是通过 RRC信令， 其 下发时间可能长达数百 ms, 在 RNC下发 RRC信令配置 4发 MIMO模式过 程中， 基站可能改变了其调度非预编码导频状态， 即在第一 UE配置为 4发 MIMO模式后， 可能会出现当前调度非预编码导频状态与第一 UE根据该调 度非预编码导频状态信息获取的调度非预编码导频状态不一致的情况。在这 种情况下， 基站可以再通知第一 UE改变调度非预编码导频状态， 即基站可 以再通过 HS-SCCH信令通知第一 UE正确的调度非预编码导频状态。然而， 由于基站需要考虑整个小区的情况来判定调度非预编码导频的激活与去激 活， 所以调度非预编码导频状态改变不会频繁发生， 而在 RNC下发 RRC信 令配置 4发 MIMO模式的过程中， 基站改变其调度非预编码导频状态的概 率会更低， 所以这种情况不会频繁地发生。
本发明实施例的指示导频状态的方法， 通过基站向 RNC发送调度非预 编码导频状态信息， 可以使 RNC向 UE发送携带该调度非预编码导频状态 信息的 4发 MIMO模式配置信令， 以使 UE在配置为 4发 MIMO模式时获 取调度非预编码导频状态， 降低了基站发送 HS-SCCH信令通知 UE调度非 预编码导频状态的概率， 从而能够降低物理层信令开销， 并降低 UE获取调 度非预编码导频状态的时延而降低调度上的时延。
应理解， 在本发明实施例中， RNC侧描述的 RNC、 基站和 UE的交互 及相关特性、 功能等与基站侧的描述相应， 为了筒洁， 在此不再赘述。
上文中结合图 1至图 3, 从 RNC的角度详细描述了指示导频状态的方 法， 结合图 4至图 6, 从基站的角度详细描述了指示导频状态的方法， 下面 将结合图 7和图 8, 从 UE的角度详细描述指示导频状态的方法。
图 7示出了根据本发明又一实施例的指示导频状态的方法 300的示意性 流程图。 如图 7所示， 该方法 300包括：
S310, 用户设备 UE接收无线网络控制器 RNC发送的 4发多输入多输 出 MIMO模式配置信令， 该配置信令携带该 RNC从基站接收的调度非预编 码导频状态信息， 该调度非预编码导频状态信息指示调度非预编码导频的激 活状态或去激活状态；
S320,该 UE在根据该配置信令配置为 4发 MIMO模式时，根据该调度 非预编码导频状态信息获取调度非预编码导频状态。
现有技术中， UE在刚配置为 4发 MIMO模式时， 不知道调度非预编码 导频是激活还是非激活， 因此还需要基站发送 HS-SCCH信令通知 UE调度 非预编码导频状态。 在本发明实施例中， 在基站向 RNC发送调度非预编码 导频状态信息后， UE接收 RNC发送的携带该调度非预编码导频状态信息的 4发 MIMO模式的配置信令，然后 UE根据该配置信令配置为 4发 MIMO模 式，并根据该调度非预编码导频状态信息获取调度非预编码导频状态。这样， UE在配置为 4发 MIMO模式时就能获取调度非预编码导频状态。 因此， 不 再需要基站发送 HS-SCCH信令通知 UE调度非预编码导频的激活或去激活 状态。
具体而言， UE接收 RNC通过 RRC信令发送的 4发 MIMO模式配置信 令。 RNC在 RRC信令中携带先前从基站接收的调度非预编码导频状态信息。 例如， RNC通过 RRC信令中 1个比特或 1个信元表示该调度非预编码导频 状态信息， 即利用 RRC信令中 1个比特或 1个信元指示调度非预编码导频 为激活状态或去激活状态。 由于 RRC信令中携带了调度非预编码导频状态 信息， UE在 4发 MIMO模式配置成功的同时， 就能获知调度非预编码导频 的激活状态或者去激活状态。 这样， 基站可以在 4发 MIMO模式配置成功 的同时使用 4发 MIMO调度数据， UE也可以根据获知的调度非预编码导频 的激活状态或去激活状态，相应地使用或不使用调度非预编码导频解调 4发 MIMO数据， 因此， 降低了调度上的时延。
因此， 本发明实施例的指示导频状态的方法， 通过 UE接收 RNC发送 的携带调度非预编码导频状态信息的 4发 MIMO模式配置信令，以及 UE在 配置为 4发 MIMO模式时根据该调度非预编码导频状态信息获取调度非预 编码导频状态， 避免了基站发送 HS-SCCH信令通知 UE调度非预编码导频 状态，从而能够降低物理层信令开销， 并降低 UE获取 4发 MIMO模式下调 度非预编码导频状态的时延。
在本发明实施例中， 可选地， 该调度非预编码导频状态信息为该基站在 改变调度非预编码导频状态后发送的。
基站根据小区状况可能会改变调度非预编码导频状态， 即通过 HS-SCCH信令通知已配置为 4发 MIMO模式的 UE改变调度非预编码导频 给 RNC,把最新的调度非预编码导频状态通知给 RNC,这样，通过接收 RNC 发送的携带调度非预编码导频状态信息的配置信令 , UE在配置为 4发 MIMO 模式时， 就能获取当前的调度非预编码导频状态。
在本发明实施例中， 如图 8所示， 可选地， 在 S320之后， 该方法 300 还包括：
S330, 该 UE接收该基站发送的改变调度非预编码导频状态信令， 并根 据该改变调度非预编码导频状态信令， 改变调度非预编码导频状态， 其中， 该改变调度非预编码导频状态信令为该基站在当前调度非预编码导频状态 与该 UE根据该调度非预编码导频状态信息获取的调度非预编码导频状态不 一致时发送的。
由于 RNC将 UE配为 4发 MIMO模式是通过 RRC信令，其下发时间可 能长达数百 ms, 在 RNC下发 RRC信令配置 4发 MIMO模式过程中， 基站 可能改变了其调度非预编码导频状态， 即在 UE配置为 4发 MIMO模式后， 可能会出现当前调度非预编码导频状态与 UE根据该调度非预编码导频状态 信息获取的调度非预编码导频状态不一致的情况。 在这种情况下， 基站可以 再向 UE发送改变调度非预编码导频状态信令， UE接收该改变调度非预编 码导频状态信令， 并根据该改变调度非预编码导频状态信令， 改变调度非预 编码导频状态， 使其与当前调度非预编码导频状态一致。
本发明实施例的指示导频状态的方法， 通过 UE接收 RNC发送的携带 调度非预编码导频状态信息的 4发 MIMO模式配置信令，以及 UE在配置为 4发 MIMO模式时根据该调度非预编码导频状态信息获取调度非预编码导频 状态， 降低了基站发送 HS-SCCH信令通知 UE调度非预编码导频状态的概 率， 从而能够降低物理层信令开销， 并降低 UE获取调度非预编码导频状态 的时延而降低调度上的时延。
应理解， 在本发明实施例中， RNC侧或基站侧描述的 RNC、基站和 UE 的交互及相关特性、 功能等与 UE侧的描述相应， 为了筒洁， 在此不再赘述。
以上分别从 RNC、 基站和 UE的角度详细描述了指示导频状态的方法， 下面将结合具体的例子详细描述本发明实施例。 应注意， 这些例子只是为了 帮助本领域技术人员更好地理解本发明实施例， 而非限制本发明实施例的范 围。
如图 9所示， UE2为小区中已经配置为 4发 MIMO模式的 UE, UE1为 小区中待配置为 4发 MIMO模式的 UE。
901 , NodeB通过 HS-SCCH信令通知 UE2改变调度非预编码导频状态。 例如， NodeB ^据目前整个小区的情况确定调度非预编码导频激活， NodeB 通过 HS-SCCH信令通知 UE2调度非预编码导频激活。
902, NodeB向 RNC发送调度非预编码导频状态信息。 例如， NodeB在 确定调度非预编码导频激活时， 通过 lub 口信令向 RNC发送调度非预编码 导频状态信息， 指示调度非预编码导频激活。
903, RNC向 UE1发送 RRC信令， 将 UE1配置为 4发 MIMO模式， 并在 RRC信令中携带调度非预编码导频状态信息。 例如， RNC在 RRC信 令中携带接收的指示调度非预编码导频激活的调度非预编码导频状态信息。
904, UE1接收 RNC发送的 RRC信令，根据 RRC信令配置为 4发 MIMO 模式， 并根据 RRC信令携带的调度非预编码导频状态信息获取调度非预编 码导频状态。 例如， UE1根据指示调度非预编码导频激活的调度非预编码导 频状态信息获取调度非预编码导频为激活状态。
905 , NodeB在 4发 MIMO模式配置成功的同时使用 4发 MIMO调度数 据。 例如， 在调度非预编码导频激活时， 直接可以发送调度非预编码导频。
906, UE1相应地解调 4发 MIMO数据。 例如， 若获知的调度非预编码 导频为激活状态， 则使用调度非预编码导频解调 4发 MIMO数据； 若获知 的调度非预编码导频为去激活状态， 则不使用调度非预编码导频解调 4发 MIMO数据。
下面结合图 10至图 12, 详细描述另一指示导频状态的方法。
图 10示出了根据本发明又一实施例的指示导频状态的方法 400的示意 性流程图。 如图 10所示， 该方法 400包括：
S410, 用户设备 UE接收无线网络控制器 RNC发送的 4发多输入多输 出 MIMO模式配置信令；
S420,该 UE在根据该配置信令配置为 4发 MIMO模式时，确定调度非 预编码导频状态为去激活。
在本发明实施例中， UE在配置为 4发 MIMO模式时， 确定调度非预编 码导频状态为去激活， 也就是说， UE确定调度非预编码导频的初始状态为 去激活。 这样， 在当前调度非预编码导频状态为去激活时， 不需要基站再发 送 HS-SCCH信令通知 UE调度非预编码导频状态。 因此， 本发明实施例的指示导频状态的方法， 通过 UE在配置为 4发 MIMO 模式时， 确定调度非预编码导频状态为去激活， 降低了基站发送 HS-SCCH信令通知 UE调度非预编码导频状态的概率， 从而能够降低物理 层信令开销，并降低 UE获取 4发 MIMO模式下调度非预编码导频状态的时 延。
在本发明实施例中， 如图 11所示， 可选地， 在 S420之后， 该方法 400 还包括：
S430, 该 UE接收基站发送的改变调度非预编码导频状态信令， 并根据 该改变调度非预编码导频状态信令， 改变调度非预编码导频状态为激活， 其 中， 该改变调度非预编码导频状态信令为该基站在确定当前调度非预编码导 频状态为激活时发送的。
在 UE确定调度非预编码导频状态为去激活之后， 若当前调度非预编码 导频状态为去激活， 则不需要基站再发送 HS-SCCH信令通知 UE调度非预 编码导频状态， 基站可以立即使用 4发 MIMO调度数据， UE也可以相应地 不使用调度非预编码导频进行解调。 若当前调度非预编码导频状态为激活， 则基站要向 UE发送改变调度非预编码导频状态信令，即基站发送 HS-SCCH 信令通知 UE调度非预编码导频状态为激活， UE根据该改变调度非预编码 导频状态信令， 改变调度非预编码导频状态为激活。
上文中结合图 10和图 11 , 从 UE的角度详细描述了指示导频状态的方 法， 下面将结合图 12, 从基站的角度详细描述指示导频状态的方法。
图 12示出了根据本发明又一实施例的指示导频状态的方法 500的示意 性流程图。 如图 12所示， 该方法 500包括：
S510,基站在用户设备 UE配置为 4发 MIMO模式并确定调度非预编码 导频状态为去激活之后， 若确定当前调度非预编码导频状态为激活， 则向该 UE发送改变调度非预编码导频状态信令， 使得该 UE改变调度非预编码导 频状态为激活。
在本发明实施例中， UE在配置为 4发 MIMO模式时确定调度非预编码 导频状态为去激活， 因此， 若当前调度非预编码导频状态为去激活， 则基站 不需要再发送 HS-SCCH信令通知 UE调度非预编码导频状态， 若当前调度 非预编码导频状态为激活， 则基站向 UE发送改变调度非预编码导频状态信 令， 即基站发送 HS-SCCH信令通知 UE调度非预编码导频状态为激活， 以 使 UE根据该改变调度非预编码导频状态信令， 改变调度非预编码导频状态 为激活。
应理解， 在本发明实施例中， UE侧描述的基站和 UE的交互及相关特 性、 功能等与基站侧的描述相应， 为了筒洁， 在此不再赘述。
下面将结合具体的例子详细描述本发明实施例。 应注意， 这些例子只是 为了帮助本领域技术人员更好地理解本发明实施例， 而非限制本发明实施例 的范围。
例如， 小区中有已配置为 4发 MIMO模式的 UE1 , NodeB根据目前整 个小区的情况确定调度非预编码导频去激活， NodeB通过 HS-SCCH信令通 知 UE1调度非预编码导频去激活。在 RNC将 UE2配为 4发 MIMO模式时，
UE2初始地认为调度非预编码导频去激活。 因为 UE2默认值和当前状态一 致， 因此， NodeB不需要发送 HS-SCCH信令给 UE2通知其调度非预编码导 频去激活。 如果 NodeB确定改变调度非预编码导频状态为激活， NodeB通 过 HS-SCCH信令通知 UE1和 UE2调度非预编码导频激活。在 RNC将 UE3 配为 4发 MIMO模式时， UE3初始地认为调度非预编码导频去激活。 因为
UE3默认值和当前状态不一致， NodeB需要发送 HS-SCCH信令给 UE3通知 其调度非预编码导频被激活。
本发明实施例的指示导频状态的方法，通过 UE在配置为 4发 MIMO模 式时， 确定调度非预编码导频状态为去激活， 降低了基站发送 HS-SCCH信 令通知 UE调度非预编码导频状态的概率， 从而能够降低物理层信令开销， 并降低 UE获取 4发 MIMO模式下调度非预编码导频状态的时延。
应理解， 在本发明的各种实施例中， 上述各过程的序号的大小并不意味 着执行顺序的先后， 各过程的执行顺序应以其功能和内在逻辑确定， 而不应 对本发明实施例的实施过程构成任何限定。
上文中结合图 1至图 12,详细描述了根据本发明实施例的指示导频状态 的方法， 下面将结合图 13至图 22, 描述根据本发明实施例的无线网络控制 器、 基站和用户设备。
图 13示出了根据本发明实施例的无线网络控制器 600的示意性框图。 如图 13所示， 该无线网络控制器 600包括：
接收模块 610, 用于接收基站发送的调度非预编码导频状态信息， 该调 度非预编码导频状态信息指示调度非预编码导频的激活状态或去激活状态； 发送模块 620 , 用于向用户设备 UE发送 4发多输入多输出 ΜΙΜΟ模式 配置信令， 该配置信令携带该调度非预编码导频状态信息， 使得该 UE在配 置为 4发 ΜΙΜΟ模式时根据该调度非预编码导频状态信息获取调度非预编 码导频状态。
在本发明实施例中，为了使 UE在配置为 4发 ΜΙΜΟ模式时获知调度非 预编码导频状态，接收模块 610接收基站发送的调度非预编码导频状态信息， 该调度非预编码导频状态信息指示调度非预编码导频的激活状态或去激活 状态， 然后， 发送模块 620向 UE发送携带该调度非预编码导频状态信息的 4发 ΜΙΜΟ模式配置信令，使得该 UE在配置为 4发 ΜΙΜΟ模式时根据该调 度非预编码导频状态信息获取调度非预编码导频状态。 由于 UE在配置为 4 发 ΜΙΜΟ模式时就能从该调度非预编码导频状态信息中获取调度非预编码 导频状态， 因此， 基站不需要再发送 HS-SCCH信令通知 UE调度非预编码 导频的激活或去激活状态。
因此， 本发明实施例的无线网络控制器， 通过向 UE发送携带 RNC从 基站接收的调度非预编码导频状态信息的 4发 ΜΙΜΟ模式配置信令， 可以 使 UE在配置为 4发 ΜΙΜΟ模式时根据该调度非预编码导频状态信息获取调 度非预编码导频状态， 避免了基站发送 HS-SCCH信令通知 UE调度非预编 码导频状态，从而能够降低物理层信令开销， 并降低 UE获取 4发 ΜΙΜΟ模 式下调度非预编码导频状态的时延。
在本发明实施例中， 可选地， 该接收模块 610具体用于接收该基站在改 变调度非预编码导频状态后发送的该调度非预编码导频状态信息。 给 RNC, 把最新的调度非预编码导频状态通知给 RNC, 这样， RNC在为之 后的 UE配置 4发 ΜΙΜΟ时，该接收模块 610就能把当前的调度非预编码导 频状态传输给该 UE。
根据本发明实施例的无线网络控制器 600可对应于根据本发明实施例的 指示导频状态的方法中的无线网络控制器， 并且无线网络控制器 600中的各 个模块的上述和其它操作和 /或功能分别为了实现图 1至图 9中的各个方法的 相应流程， 为了筒洁， 在此不再赘述。

发送模块 720, 用于向无线网络控制器 RNC发送该调度非预编码导频 状态信息， 使得该 RNC向第一用户设备 UE发送携带该调度非预编码导频 状态信息的 4发多输入多输出 MIMO模式配置信令，以使该第一 UE在配置 为 4发 MIMO模式时根据该调度非预编码导频状态信息获取调度非预编码 导频状态。
在本发明实施例中， 第一 UE表示待配置为 4发 MIMO模式的 UE。 为 了使第一 UE在配置为 4发 MIMO模式时获知调度非预编码导频状态，发送 模块 720向 RNC发送调度非预编码导频状态信息， 这样， RNC向第一 UE 发送携带该调度非预编码导频状态信息的 4发多输入多输出 MIMO模式配 置信令，从而使第一 UE在配置为 4发 MIMO模式时根据该调度非预编码导 频状态信息获取调度非预编码导频状态。因此，基站不需要再发送 HS-SCCH 信令通知第一 UE调度非预编码导频的激活或去激活状态， 并且， 基站可以 在 4发 MIMO模式配置成功的同时使用 4发 MIMO调度数据， 第一 UE也 可以根据获知的调度非预编码导频的激活状态或去激活状态，相应地使用或 不使用调度非预编码导频解调 4发 MIMO数据， 因此， 降低了调度上的时 延。
这样， 本发明实施例的基站， 通过向 RNC发送调度非预编码导频状态 信息， 可以使 RNC 向 UE发送携带该调度非预编码导频状态信息的 4发 MIMO模式配置信令，以使 UE在配置为 4发 MIMO模式时根据该调度非预 编码导频状态信息获取调度非预编码导频状态， 避免了基站发送 HS-SCCH 信令通知 UE调度非预编码导频状态， 从而能够降低物理层信令开销， 并降 低 UE获取 4发 MIMO模式下调度非预编码导频状态的时延。
在本发明实施例中， 可选地， 该发送模块 720还用于在该确定模块 710 确定该调度非预编码导频状态信息之前， 通知第二 UE改变调度非预编码导 频状态， 其中， 该第二 UE表示已配置为 4发 MIMO模式的 UE。
基站在确定改变调度非预编码导频状态时通过 HS-SCCH信令通知第二 UE,即已配置为 4发 MIMO模式的 UE,改变调度非预编码导频状态。并且， 基站发送调度非预编码导频状态信息给 RNC, 把最新的调度非预编码导频 状态通知给 RNC, 这样， RNC在为第一 UE配置 4发 MIMO时， 就能把当 前的调度非预编码导频状态传输给该 UE。
在本发明实施例中， 可选地， 该发送模块 720还用于在向无线网络控制 器 RNC发送调度非预编码导频状态信息之后， 在当前调度非预编码导频状 态与该第一 UE根据该调度非预编码导频状态信息获取的调度非预编码导频 状态不一致时， 通知该第一 UE改变调度非预编码导频状态。
根据本发明实施例的基站 700可对应于根据本发明实施例的指示导频状 态的方法中的基站，并且基站 700中的各个模块的上述和其它操作和 /或功能 分别为了实现图 1至图 9中的各个方法的相应流程， 为了筒洁， 在此不再赘 述。
图 15示出了根据本发明实施例的用户设备 800的示意性框图。 如图 15 所示， 该用户设备 800包括：

处理模块 820, 用于在根据该配置信令配置为 4发 MIMO模式时， 根据 该调度非预编码导频状态信息获取调度非预编码导频状态。
在本发明实施例中，在基站向 RNC发送调度非预编码导频状态信息后， 接收模块 810接收 RNC发送的携带该调度非预编码导频状态信息的 4发 MIMO模式的配置信令， 然后处理模块 820根据该配置信令配置为 4发 MIMO模式，并根据该调度非预编码导频状态信息获取调度非预编码导频状 态。这样， UE在配置为 4发 MIMO模式时就能获取调度非预编码导频状态。 因此， 不再需要基站发送 HS-SCCH信令通知 UE调度非预编码导频的激活 或去激活状态。
因此， 本发明实施例的用户设备， 通过接收 RNC发送的携带调度非预 编码导频状态信息的 4发 MIMO模式配置信令， 在配置为 4发 MIMO模式 时根据该调度非预编码导频状态信息获取调度非预编码导频状态，避免了基 站发送 HS-SCCH信令通知 UE调度非预编码导频状态， 从而能够降低物理 层信令开销，并降低 UE获取 4发 MIMO模式下调度非预编码导频状态的时 延。
在本发明实施例中， 可选地， 该调度非预编码导频状态信息为该基站在 改变调度非预编码导频状态后发送的。
在本发明实施例中， 可选地， 该接收模块 810还用于在该处理模块 820 根据该调度非预编码导频状态信息获取调度非预编码导频状态之后，接收该 基站发送的改变调度非预编码导频状态信令， 该处理模块 820还用于根据该 改变调度非预编码导频状态信令， 改变调度非预编码导频状态， 其中， 该改 变调度非预编码导频状态信令为该基站在当前调度非预编码导频状态与该 用户设备根据该调度非预编码导频状态信息获取的调度非预编码导频状态 不一致时发送的。

处理模块 920, 用于在根据该配置信令配置为 4发 MIMO模式时， 确定 调度非预编码导频状态为去激活。
在本发明实施例中， 处理模块 920在配置为 4发 MIMO模式时， 确定 调度非预编码导频状态为去激活， 也就是说， UE确定调度非预编码导频的 初始状态为去激活。 这样， 在当前调度非预编码导频状态为去激活时， 不需 要基站再发送 HS-SCCH信令通知 UE调度非预编码导频状态。
因此， 本发明实施例的用户设备， 通过在配置为 4发 MIMO模式时， 确定调度非预编码导频状态为去激活， 降低了基站发送 HS-SCCH信令通知 UE调度非预编码导频状态的概率， 从而能够降低物理层信令开销， 并降低 UE获取 4发 MIMO模式下调度非预编码导频状态的时延。
