Description

获取信道特性的方法、 用户设备及基站
技术领域 本发明涉及通信技术, 尤其涉及一种获取信道特性的方法、 用户设备及 基站。
背景技术
长期演进( Long Term Evolution, LTE ) 系统中, 可以通过传输一个天线 端口上信号的信道可以推断出传输另一个天线端口上信号的信道的大尺度特 性, 那么这两个天线端口被称作是准共站(QCL, Quasi-Co-Location )。 其中, 信道的大尺度特性包括: 时延扩展(Delay Spread ), 多普勒扩展 ( Doppler Spread ), 多普勒偏移 (Doppler Shift )、 平均增益(Average Gain )和平均时 延 ( Average Delay ) 中的一项或多项。 例如, 用户设备(User Equipment, UE )可以根据基站发送的准共站配 置信息, 确定解调参考信号 (Demodulation Reference Signal, DM RS )天线 端口和同一个小区高层信令配置的一个 CSI-RS 的天线端口是准共站的。 再 如, UE还可以根据基站发送的配置信息, 确定高层信令配置的一个 CSI-RS 天线端口和同一个小区高层信令配置的一个 CRS的天线端口是准共站的。 由于基站配置的准共站的天线端口都在相同的载波上, 而 UE只能根据 相同载波上的天线端口所对应的信道特性来获得 DM RS或 CSI-RS的信道大 尺度特性。 因此, 对于载波上的小区中没有 CRS或者没有 CSI-RS情况, 该 载波上的小区的天线端口无法实现准共站, 并且, 如果准共站只能在同一个 载波上进行, 也会使准共站的增益受到很大的限制。

本实施例中, UE通过获取准共站配置信息, 并以此确定不同载波上的天 线端口即跨载波的天线端口之间的准共站的信道特性, 从而解决了某些同一 载波上的小区没有某些参考信号时导致无法进行准共站配置的问题, 实现了 跨载波的天线端口的准共站, 并且使准共站配置更加灵活。 本发明提供的另一个实施例与图 1所示的实施例类似, 不同之处在于, 本实施例中, 准共站配置信息是预定义的, 且准共站配置信息中包括了第一 天线端口的载波信息, 且载波信息至少为小区信息。 本实施例中, 准共站配置信息是预定义的, 其中该准共站配置信息中包 括预定义的第一天线端口所属的第一小区信息。
例如, 该预定义的第一天线端口所属的第一小区可以为发送物理下行控 制信道( Physical Downlink Control CHannel, PDCCH )和 /或增强的物理下行 控制信道 ( Enhanced-Physical Downlink Control Channel, ePDCCH ) 的小区; 或,
该预定义的第一天线端口所属的第一小区可以为网络侧如基站为所述 UE配置的主小区; 或, 该预定义的第一天线端口所属的第一小区可以为下行控制信息 ( Downlink Control information, DCI )中载波指示域 ( Carrier Indicator Field, CIF )对应的小区。 其中, 所述第一小区与第一载波对应, 所述第一载波为所述第一天线端 口所属的载波。 可选的, UE也可以接收基站通知的第一小区信息, 该第一小区信息可以 由基站隐式通知。 本实施例中, UE通过根据预定义获取准共站配置信息,且准共站配置信 息包括了第一天线端口的载波信息, 且载波信息至少为小区信息, 并以此确 定不同载波上的天线端口即跨载波的天线端口之间的准共站的信道特性, 从 而解决了某些同一载波上的小区没有某些参考信号时导致无法进行准共站配 置的问题, 实现了跨载波的天线端口的准共站, 并且使准共站配置更加灵活。 本发明提供的另一个实施例与图 1所示的实施例类似, 不同之处在于, 本实施例中, 准共站配置信息可以是由基站通知 UE, UE根据基站通知来获 取准共站配置信息, 如下:
基站通知可以为显式通知或隐式通知: 显式通知包括: 通过准共站相关专用信令进行准共站配置信息的通知。 例如, 基站可以通过半静态信令通知, 如无线资源控制 ( Radio Resource Control, RRC )信令通知; 或者 基站可以通过动态信令通知, 如 DCI通知; 或者
基站可以通过半静态信令和动态信令联合通知,如基站通过 RRC信令通 知 N个状态, 每一个状态对应一种用于第二小区的第二天线端口 QCL假设 的小区及天线端口配置, 再通过 DCI通知 DCI指示的子帧上 QCL 没对应 的状态的信息。
隐式通知可以为: 通过非准共站相关专用信令进行通知。 如基站通知 UE—个小区的参考 载波, 那么除非显式通知用于指示准共站参考的第一天线端口的载波信息, 否则用于准共站参考的第一天线端口都是对应该参考载波的天线端口; 或者 基站通知 UE—个小区的参考小区, 那么除非显式通知用于指示准共站 参考的第一天线端口的载波信息, 否则用于准共站参考的第一天线端口都是 对应该参考小区的天线端口; 或者 基站通知 UE—个小区的参考载波上的参考小区, 那么除非显式通知用 于指示准共站参考的第一天线端口的载波信息, 否则用于准共站参考的第一 天线端口都是对应该参考载波上的该参考小区的天线端口。 本实施例中, 准共站配置信息中还可以包括所述第一天线端口的载波信 息。 该载波信息可以为以下至少一种信息: 小区标识信息或载波标识信息, 其中小区标识信息可以为服务小区索引号信息; 载波标识信息可以为载波频 率索引号信息。 该载波信息可以是预定义的, 网络侧显式通知的或网络侧隐 式通知的。 该准共站配置信息可以包含在上述第二天线端口对应的信号的配置信息 中, 如所述第二天线端口对应的配置信息中包括上述第一天线端口对应的信 号的载波信息和 /或相关索引号等。 举例如下: 该第一天线端口为小区专属参 考信号( CRS )的天线端口,该第二天线端口为 CSI-RS的天线端口,该 CSI-RS 的配置信息包括该 CRS的载波信息, 如该 CRS对应的服务小区索引号。 基站通知 UE准共站配置信息之前, 在配置准共站信息时, 可以釆用方 式一或方式二配置 UE: 方式一, 第一小区的第一信号的天线端口和第二小区的第二信号的天线 端口关于至少一个信道特性是准共站的; 例如, 第一小区的某一个 CSI-RS的 天线端口和第二小区的 CRS或 RCRS ( reduced CRS , 一种占用 RE数量减小 的 CRS ) 的天线端口关于至少一个信道特性是准共站的。
方式二, 第一小区的第一信号的天线端口和第一小区的第三信号的天线 端口关于至少一个信道特性(如信道特性 A、 B、 C或 D )是准共站的, 而第 一小区的第三信号和第二小区的第二信号的天线端口关于至少一个信道特性 (如信道特性 A或 B )是准共站的。 从而第一小区的第一信号的天线端口和 第二小区的第二信号的天线端口关于至少一个信道特性(如信道特性 A或 B ) 是准共站的。 例如:第一小区的某一个 CSI-RS的天线端口和第一' 区的 CRS或 RCRS 的天线端口中至少一个信道特性是准共站的, 而第一小区的 CRS或 RCRS的 天线端口和第二小区的 CRS或 RCRS的天线端口中所述至少一个信道特性是 准共站的。从而第一小区的该 CSI-RS的天线端口和第二小区的 CRS或 RCRS 的天线端口中所述至少一个信道特性是准共站的。 进一步, UE可以根据第二小区的 CRS或 RCRS的天线端口上接收的信 号获得第一小区的该 CSI-RS的天线端口的所述至少一个信道特性, 或者 UE 可以根据第一' j、区的 CRS或 RCRS的天线端口和第二小区的 CRS或 RCRS 的天线端口上接收的信号获得第一小区的该 CSI-RS 的天线端口的所述至少 一个信道特性。 可选地,基站还可以通知 UE—个偏差配置信息, 以用于 1¾ ^_设第一天 线端口与第二天线端口之间中至少一个信道特性的偏差值, 且根据偏差值调 整后, 第一天线端口与第二天线端口中至少一个信道特性是准共站的。 具体地, 该偏差值可为一个相对值, 如第一天线端口的时间域信道特性 比第二天线端口的时间域信道特性偏差值。 这里, 信道特性的偏差值, 可以为时间域信道特性、 频率域信道特性和 功率域信道特性中的至少一个信道特性的偏差值。 当偏差值为 0时, 该偏差值不需要通知给 UE, 或当 UE没接受到该偏差 值时, UE假设偏差值为 0。 本实施例中, UE通过接收偏差配置信息, 并对跨载波的天线端口中的信 道特性根据偏差配置信息中的偏差值进行调整, 之后达到准共站, 进一步实 现了跨载波的天线端口的准共站, 并且使准共站配置更加灵活。 本发明提供的另一个实施例与图 1所示的实施例类似, 不同之处在于, 本实施例中, 一部分准共站配置信息可以由基站通知 UE, —部分准共站配置 信息可以由 UE预定义。 其中, 一部分准共站配置信息可以由基站通知 UE 包括, 基站显式通知 的和 /或基站隐式通知的。 本实施例中, 一部分准共站配置信息由基站通知 UE, —部分准共站配置 信息由 UE预定义, 使得 UE获取准共站配置信息的方式更加灵活。 本发明提供的另一个实施例与图 1所示的实施例类似, 不同之处在于, 本实施例中, UE获取的准共站配置信息用于指示上述第一天线端口和第二天 线端口关于平均增益是准共站的, 其中, 获取准共站配置信息的方式也可釆 用实施例二、 实施例三中所示的方法。 本实施例中, 获取信道特性的方法还包括: UE上 4艮一个 RSRP值。 该 RSRP值从上述第一天线端口和第二天线端口中的至少一个天线端口上测量 处理后得到。 具体的, UE可以根据第一天线端口测量一个 RSRP值, 根据第二天线端 口测量一个 RSRP值, UE上报第一天线端口上测量得到的 RSRP值或第二天线 端口上测量得到的 RSRP值, 或将两个 RSRP值进行统计平均或加权平均后得 到一个最终的 RSRP值, 并将得到的最终的 RSRP值上报。 或者,UE可以根据第一天线端口和第二天线端口联合测量一个 RSRP值, 并将联合测量得到的 RSRP值上报。 或者, 本实施例中, UE获取了准共站配置信息之外, 还接收了偏差配置 信息, 偏差配置信息用于指示: 上述第一天线端口和第二天线端口根据偏差 值调整后关于平均增益是准共站的。 其余部分与图 1所示实施例类似, 获取 准共站配置信息的方式也可釆用上述实施例中所示的方法, 获取偏差配置信 息的方式也可釆用上述实施例所示的方法。 当偏差配置信息用于指示: 上述第一天线端口和第二天线端口根据功率 偏差值调整后关于平均增益是准共站的时, UE接收了偏差配置信息之后, 获 取信道特性的方法还包括: UE上报一个 RSRP值。 该 RSRP值由 UE在该第 一天线端口和第二天线端口上测量得到, 或者由 UE根据该第一天线端口和 第二天线端口中的任意一个天线端口的测量结果以及该功率偏差值得到。 如 第一天线端口相对第二天线端口偏差值为 +3dB, 那么将在第一天线端口上测 量得到的 RSRP值减去 3dB后得到第二天线端口的 RSRP值。 具体地, 对于第一天线端口和第二天线端口关于平均增益准共站, 以及 第一天线端口和第二天线端口根据功率偏差值调整后平均增益是准共站的两 种情况, UE可以根据第一天线端口测量一个 RSRP值, 根据第二天线端口测 量一个 RSRP值, 然后将两个 RSRP值进行统计平均或加权平均后得到一个 最终的 RSRP值, 并将得到的最终的 RSRP值上报。 或者, UE可以根据第一 天线端口和第二天线端口联合测量一个 RSRP值, 并将测量得到的 RSRP值 上报。
当第一天线端口和第二天线端口根据功率偏差值调整后, 平均增益是准 共站的时, UE根据第一天线端口测量一个 RSRP值, 并根据配置的平均接收 功率偏差值进行调整, 如第一天线端口相对第二天线端口偏差值为 +3dB, 那 么将测量得到的 RSRP值减去 3dB后得到一个 RSRP值, 根据第二天线端口 测量另一个 RSRP值, 然后将这两个 RSRP值进行统计平均或加权平均后得 到一个最终的 RSRP值, 并将得到的最终的 RSRP值上报。 本实施例中, UE 通过获取的准共站配置信息和 /或偏差配置信息得到 RSRP值, 并上报, 使得跨载波天线端口的准共站的应用更加广泛。 本发明提供的另一个实施例与图 1所示的实施例类似, 不同之处在于, 根据图 1所示实施例, 当所述偏差配置信息用于指示: 上述第一天线端口和 第二天线端口的平均时延根据时间偏差值调整后是准共站的时, UE根据该第 一天线端口的接收时间及该时间偏差值, 获得该第二天线端口的接收时间。 其中, 第二天线端口接收时间等于第一天线端口接收时间与该时间偏差值之 和, 其中的接收时间偏差值还可以为平均时延偏差值。 例如, 若所述第一天线端口比所述第二天线端口对应的接收时间提前, 且所述第一天线端口和所述第二天线端口之间的接收时间偏差值为 D us , UE 根据第一天线端口上的信号获得第一天线端口的接收时间, 那么 UE可以认 为 UE根据第一天线端口对应的接收时间再加上 D us后即为第二天线端口对 应的接收时间。 当所述偏差配置信息用于指示: 上述第一天线端口和第二天线端口根据 频率偏差值调整后, 该第一天线端口和第二天线端口中多普勒扩展和多普勒 偏移是准共站的时, UE根据该第一天线端口的接收频率和该频率偏差值获得 该第二天线端口的接收频率; 其中, 频率偏差值为该第一天线端口对应载波 与该第二天线端口对应载波之间的中心频率偏差值。 其中, 第二天线端口接 收频率等于第一天线端口接收频率与中心频率偏差值之和。 例如, 若所述第一天线端口对应的载波的中心频率比所述第二天线端口 对应的载波的中心频率低, 所述第一天线端口对应的载波和所述第二天线端 口对应的载波之间的中心频率差为 A MHz, UE根据第一天线端口上的信号 获得的接收频率为 B MHz, 那么 UE 可以认为第二天线端口的接收频率为 ( A+B ) MHz0 进一步地, 本发明实施例提供的方法还可以包括: UE根据上述第一天线端口上接收的信号,测量该第一天线端口的频率误 差;
相应地, UE根据该第一天线端口的接收频率和上述中心频率偏差值获得 该第二天线端口的接收频率, 可以包括:
UE根据该中心频率偏差值、第一天线端口的接收频率及频率误差, 获得 该第二天线端口的接收频率。 举例如下: 若所述第一天线端口对应的载波的中心频率比所述第二天线 端口对应的载波的中心频率低, 所述第一天线端口对应的载波和所述第二天 线端口对应的载波之间的中心频率偏差值为 A MHz, UE根据第一天线端口 上的信号获得的接收频率为 B MHz, UE根据第一天线端口上的信号获得的 频率误差为 C Hz,那么 UE可以认为第二天线端口的接收频率为( A+B )MHz + C Hz。 本实施例中, UE通过获取的准共站配置信息和 /或偏差配置信息和 /或频 率误差得到天线端口的接收频率, 使得跨载波天线端口的准共站的应用更加 广泛。 图 2为本发明另一个实施例提供的用于获取信道特性的方法的流程图。 本实施例中, 用于获取信道特性的方法包括: 步骤 21、 基站为 UE配置准共站, 该准共站包括第一天线端口与第二天 线端口中至少一个信道特性是准共站的, 该第一天线端口和第二天线端口分 别对应不同的载波。 例如, 基站为 UE配置不同载波上的第一天线端口与第二天线端口中某 一信道特性或某些信道特性是准共站的。 其中, 信道特性可包括以下至少一项: 时间域信道特性, 频率域信道特 性, 功率域信道特性。 或者, 信道特性可包括以下至少一项: 时延扩展, 多普勒扩展, 多普勒 偏移, 平均增益, 平均接收功率, 平均时延, 接收时间, 接收频率, 参考信 号接收功率 RSRP。 步骤 22、 基站向上述 UE发送准共站配置信息, 以使该 UE根据该准共 站配置信息确定该第一天线端口与第二天线端口中至少一个信道特性是准共 站的, 并从该第一天线端口或该第一天线端口和该第二天线端口上接收的信 号, 获取该第二天线端口中与该第一天线端口准共站的至少一个信道特性。
