Description

一种确定上行信号发射功率的方法及设备
本申请要求在2017年5月5日提交中国专利局、申请号为201710314124.0、发明名称为“一种确定上行信号发射功率的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种确定上行信号发射功率的方法及设备。
背景技术
目前，在第五代移动通信系统中，主要提出了两种类型的基站，分别为长期演进(Long Term Evolution，LTE)基站和新空口(New Radio，NR)基站。对于这两种类型的基站，功能相类似，主要区别为部署频段的不同。在现有技术中，NR基站主要部署在高频频段，而LTE基站主要部署在低频频段。由于在无线通信系统中，载波的频率越高，路径损耗越大，上行覆盖越差。而NR基站由于部署在高频频段，因此，NR基站存在上行覆盖受限的问题。
为了解决NR基站上行覆盖受限的问题，相关技术人员提出了，如下解决方案：在LTE基站的上行轻载时，NR基站将共享LTE基站的上行载波资源，如此，既能提高LTE基站的上行资源利用率，又可提高NR基站的上行覆盖。比如，如图1所示，LTE基站的上行工作频段为1.75GHZ，下行工作频段为1.85GHZ，上行工作频段1.75GHZ与下行工作频段1.85GHZ相绑定。NR基站的上行工作频段为3.4GHZ，下行工作频段为3.5GHZ，上行工作频段3.4GHZ与下行工作频段3.5GHZ相绑定。在LTE基站的上行轻载时，NR基站可利用LTE基站的1.75GHZ的上行载波进行上行数据传输。
为了方便进行介绍，以下定义了两种终端，分别为LTE终端和NR终端，LTE终端为选择LTE基站作为服务基站的终端，LTE终端使用LTE制式接收来自LTE基站下行信号，传输上行信号给LTE基站；NR终端为选择NR基站作为服务基站的终端，NR终端使用NR制式接收来自NR基站下行信号，传输上行信号给NR基站。由于在实际应用中，无论是LTE终端，还是NR终端在上行数据传输时，首先都要估计上行路径损耗，然后根据所估计的上行路径损耗，确定上行信号的发射功率，比如所估计的上行路径损耗越大，上行信号的发射功率越大，才能保证基站能正确接收并解调上行信号。在现有技术中，对于NR终端在LTE基站的共享上行载波上传输上行信号，将在NR高频下行载波上测量的下行路径损耗，作为在共享上行载波上的上行路损耗，计算上行信号的发射功率，将会导致NR终端的上行传输性能下降，甚至影响LTE终端的上行传输，比如，NR终端的随机接入前导码发射功率过大，将会淹没与其共享上行载波的LTE终端的随机接入前导码。

具体实施方式
为了便于理解，示例的给出了与本申请相关概念的说明以供参考，如下所示：
基站(base station，BS)设备，也可称为基站，是一种部署在无线接入网用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(base transceiver station,BTS)和基站控制器(base station controller,BSC)，3G网络中提供基站功能的设备包括节点B(英文NodeB)和无线网络控制器(radio network controller,RNC)，在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在WLAN中，提供基站功能的设备为接入点(access point，AP)。在未来5G网络如新无线(New Radio，NR)或LTE+中，提供基站功能的设备包括继续演进的节点B(gNB)，TRP(transmission and reception point，收发点)，或TP(transmission point，传输点)。其中，TRP或TP可以不包括基带部分，仅包括射频部分，也可以包括基带部分和射频部分。

网络设备，是指位于无线通信网络中位于网络侧的设备，可以为接入网网元，如基站或控制器(如有)，或者，也可以为核心网网元，还可以为其他网元。
下面结合附图，对本申请的技术方案进行介绍：
图2示出了本申请实施例的一种可能的系统网络示意图。如图1所示，至少包括一个UE与无线接入网(radio access network,RAN)进行通信。所述RAN包括至少第一基站和第二基站，所述第一基站和第二基站可布署在不同的频段，比如，第一基站可布署在高频频段，比如在第五代移动通信系统中，第一基站可为NR基站，第二基站可布署在低频频段，比如在第五代移动通信系统中，第二基站可为LTE基站。为了清楚起见，图中只示出了第一基站和第二基站两个基站，以及一个UE。所述RAN与核心网络(core netwrork，CN)相连。可选的，所述CN可以耦合到一个或者更多的外部网络(external network)，例如英特网、公共交换电话网(public switched telephone network，PSTN)等。
应当指出，所述高频频段是指频率大于预设频率的频段，低频频段是指频率小于预设 频率的频率，比如，将大于2.6GHZ的频段作为高频频段，将小于2.6GHZ的频段作为低频频段。
在本申请中，第一基站可包括第一上行载波和第一下行载波，且当所述第一上行载波为第一FDD载波中的上行载波时，第一下行载波为第一FDD载波中的下行载波，当所述第一上行载波为第一TDD载波中的上行时隙集合时，所述第一下行载波为第一TDD载波中的下行时隙集合。第二基站可包括第二上行载波和第二下行载波，且当所述第二上行载波为第二FDD载波中的上行载波时，所述第二下行载波为第二FDD载波中的下行载波，当所述第二上行载波为第二TDD载波的上行时隙集合时，所述第二下行载波为第二TDD载波中的下行时隙集合。

表1
应当理解，在本申请中，第一基站和第二基站可布署在不同的频段，比如，所述第一基站可部署在高频频段，比如第一上行载波的频段可为3.4G，第一下行载波的频段可为3.5G，所述第一基站可为5G中的NR基站，或者所述第一上行载波为3.5G TDD载波的上行时隙集合，第一下行载波为3.5G TDD载波的下行时隙；第二基站可部署在低频频段，比如第二上行载波的频段可为1.75G，第二下行载波的频段可为1.85G，所述第二基站可为4G中的LTE基站。
在本申请中，将以第一基站布署在高频频段、第二基站布署在低频频段为例，详细介绍本申请的技术方法。
应当指出，在无线通信系统中，载波的频率载高，路径损耗将越大，因此，对于布署在高频频段的第一基站存在上行覆盖受限的情况(尤其对于第一基站的边缘用户，情况更严重)。因此，相关技术人员提出了，第一基站在第二基站上行载波轻载时，可利用第二 基站的上行载波(比如1.75G)进行上行信号的传输；由于对于第二基站，存在与上行载波相匹配的下行载波(比如1.85G)，因此可利用下行载波进行上行路径耗损的估计；但是，对于驻留第一下行载波的终端使用共享的第二上行载波时并不存在相匹配的第二下行载波；因此，出现驻留第一下行载波的终端在利用共享第二的上行载波进行上行信号的传输时，无法准确估计上行路径损耗的情况，相对应的，也就无法准确计算上行信号的发射功率。或者说，驻留在第一下行载波的终端基于第一下行载波进行第二共享上行路径损耗的估计，此时会出现上行路径损耗的估计过大，从而使得驻留在第一下行载波在共享第二上行载波上的上行信号的发射功率过大，从而影响第二共享上行载波上两个系统上行信号的传输性能
基于此，本申请提供了一种确定上行信号发射功率的方法，利用本申请的方法，可利用第一基站现存的下行载波上的下行参考信号做路损估计，从而使得驻留在第一下行载波的终端在共享第二上行载波上发送上信号时，能够比较准确的计算出上行信号的发射功率，从而提高通过第二上行载波发送给第一基站的上行信号的性能，避免影响通过第二上行载波发送给第二基站的上行信号。
应当指出，所述第一基站和第二基站可以共站建设，也可各自独立建站。而本申请描述的第一”、“第二”等词汇，仅用于区分描述，而不用于指示或暗示相对重要性，也不用于指示或暗示顺序。本申请中的上行信号可以是上行信号，也可以是上行信道。
本申请实施例中部分场景以无线通信网络中4G网络场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
需指出的是，本申请实施例中的方法或装置可以应用于无线网络设备和用户设备之间，也可以应用于无线网络设备和无线网络设备(如宏基站和微基站)之间，还可以应用于用户设备和用户设备(如D2D场景)之间，在本申请所有实施例中，以无线网络设备和无线网络设备之间的通信为例进行描述。
图3为本申请提供的一种确定上行信号发射功率的方法的流程，该流程中的网络设备可对应于图2中的第一基站，终端设备对应于图2中的UE，如图3所示，包括：
步骤S31：网络设备生成消息。
其中，所述消息中携带有第一上行载波相关的第一损耗参数、第二上行载波相关第二损耗参数；
步骤S32：网络设备发送消息至终端设备。
可选的，所述网络设备可在第一下行载波上发送所述消息；且所述所述第一下行载波包括以下至少一种：第一FDD载波中的下行载波和第一TDD载波的下行时隙集合；当所述第一上行载波为所述第一FDD载波中的上行载波时，所述第一下行载波为所述第一FDD载波中的下行载波，当所述第一上行载波为第一TDD载波的上行时隙集合时，所述第一下行载波为第一TDD载波的下行时隙集合。

步骤S34：终端设备计算上行信号的发射功率。
其中，所述上行信号采用所述第一上行载波发送，所述上行信号的发射功率基于所述第一损耗参数计算获得，或者，所述上行信号采用所述第二上行载波发送，所述上行信号 的发射功率基于所述第二损耗参数计算获得。
在本申请中，终端设备如何计算上行信号的发射功率，可以下述三种情况为示例，进行说明。应当理解，下述三种情况仅为示例性的说明，并不能作为对本申请保护范围的限制。
第一种：所述第一损耗参数为第一路径损耗补偿因子，所述第二损耗参数为第二路径损耗补偿因子，且所述第一路径损耗补偿因子与所述第二路径损耗补偿因子的值不同；所述终端设备在采用所述第一上行载波发送所述上行信号时，基于所述第一路径损耗补偿因子，计算所述上行信号的发射功率；而所述终端设备在采用所述第二上行载波发送所述上行信号时，基于所述第二路径损耗补偿因子，计算所述上行信号的发射功率。
第二种：所述第一损耗参数为第一功率攀升因子，所述第二损耗参数为第二功率攀升因子，且所述第一功率攀升因子与所述第二功率攀升因子的值不同；所述终端设备在采用所述第一上行载波发送所述上行信号时，基于所述第一功率攀升因子，计算所述上行信号的发射功率；所述终端设备在采用所述第二上行载波发送所述上行信号时，基于所述第二功率攀升因子，计算所述上行信号的发射功率。
第三种：所述第一损耗参数为第一路径损耗调整因子，所述第二损耗参数为第二路径损耗调整因子，且所述第一路径损耗调整因子与所述第二路径损耗调整因子的值不同；所述终端设备在采用所述第一上行载波发送所述上行信号时，基于所述第一路径损耗调整因子，计算所述上行信号的发射功率；所述终端设备在采用所述第二上行载波发送所述上行信号时，基于所述第二路径损耗调整因子，计算所述上行信号的发射功率。
在本申请的另一可行实施例中，上述方法可具体应用于终端设备的随机接入过程中上行信号的发射功率计算。如图4所示，随机接入的过程如下：
步骤S41：终端设备发送随机接入第一消息到网络设备，例如，随机接入过程中的Message1(Msg1)。
其中，随机接入第一消息可具体为preamble(随机接入前导码)。
步骤S42：网络设备发送随机接入第二消息至终端设备，例如，随机接入过程中的Message2(Msg2)。
其中，M随机接入第二消息可具体为RAR(Random Access Response，随机接入响应)，所述RAR可具体为网络设备在接收到终端设备发送的preamble后发送的。
步骤S43：终端设备发送随机接入第三消息至网络设备，例如，在随机接入过程中的Message3(Msg3)。
所述随机接入第三消息主要为RRC请求。一种情况：如果是初次接入(initial access)，Msg3为在CCCH上传输的RRC Connection Request，且至少需要携带NAS UE标志信息。另一种情况，如果是切换(handover)，Msg3为在DCCH上传输的经过加密和完整性保护的RRC Handover Confirm，必须包含UE的C-RNTI，且如果可能的话，需要携带BSR。另一种情况如果是RRC连接重建(RRC Connection Re-establishment)，Msg3为CCCH上传输的RRC Connection Re-establishment Request，且不携带任何NAS消息。另一种情况对于其它触发事件，则Msg3中至少需要携带C-RNTI。
步骤S44：网络设备发送随机接入第四消息至终端设备，例如，在随机接入过程的Message4(Msg4)。
随机接入第四消息主要用于竞争解决，确定UE的temp CRNTI为CRNTI。
利用图3所提供的方法，可用于计算随机接入前导码的发送功率，具体如下：
第一种：图3所示的方法中的第一损耗参数为第一路径损耗补偿因子，第二损耗参数为第二路径损耗补偿因子，计算preamble发射功率，符合下述公式：
PreambleReceivedTarget Power＝preambleInitialReceivedTargetPower+deltaPreamble+(preambleTransmissionConter-1)*powerRampingStep
P_PRACH＝min{P_CMAX,PreambleReceivedTargetPower+alpha(cc)*PL}；公式(1)
其中，所述P_PRACH代表所述随机接入前导码的发射功率；所述P_CMAX代表所述终端设备的最大发射功率；所述PreambleReceivedTargetPower代表所述网络设备期望接收到所述随机接入前导码的功率；所述PL代表所述终端设备根据第一下行载波上的参考信号测量得到的下行路径损耗；所述preambleInitialReceivedTargetPower代表所述终端设备在当前随机接入过程中，所述网络设备期望所接收到的所述第一个随机接入前导码的功率；所述deltaPreamble代表与所述随机接入前导码的类型相关的调整量；所述preambleTransmissionConter代表所述终端设备在当前随机接入过程中，发送所述随机接入前导码的次数；所述powerRampingStep代表所述终端设备在当前随机接入过程中，相邻两次发送的所述随机接入前导码之间的功率攀升因子；所述alpha(cc)代表所述路径损耗补偿因子。
在本申请中，当终端设备采用第一上行载波，发送随机接入前导码时，所述alpha(cc)取值为第一路径损耗补偿因子，而终端设备采用第二上行载波，发送随机接入前导码时，所述所述alpha(cc)取值第二路径损耗补偿因子。
应当指出，上述公式(1)相对于现有技术中，计算上行信号发射功率的改进，主要在alpha(cc)；上述公式(1)中的PL为终端设备基于网络设备现有的第一下行载波(比如3.5G)，所述下行路损是基于第一下行载波上的参考信号测量得到，下行参考信号可以为小区参考信号CRS、信道状态参考信号CSI-RS、同步信号块SS-Block等等；比如，终端设备在第一下行载波上接收参考信号，然后基于该参数信号，计算终端设备在第一下行载波上的下行路径损耗。而当终端设备采用第一上行载波发送随机接入前导码时，所述alpha(cc)的值取1；所述第一下行载波与第一上行载波相匹配，比如，第一下行载波与第一上行载波在频域上相匹配，可以像LTE中RAN4定义属于一个band，比如，第一下行载波为3.5G，第一上行载波为3.4G；或者，第一下行载波与第一上行载波在时域上相匹配，比如第一下行载波为第一载波的下行时隙集合，那么第一上行载波为第一载波的上行时隙集合。而当终端采用第二上行载波发送随机接入码时，所述alpha(cc)的值非1，第二上行载波与第一下行载波并不相匹配(所述第二上行载波与第一下行载波不匹配，主要是指第二上行载波与第一下行载波频率间距比较大，基于下行路损估计上行路损不在准确)，关于第二上行载波与第一下行载波不相匹配的解释，可参见上述第一上行载波与第一下行载波相匹配的解释。在本申请中，比如，第二上行载波可为1.75G，第一下行载波可为3.5G。在本申请中，当第二上行载波的频率大于第一上行载波的频率时，alpha(cc)大于1，且两者的差值越大，alpha(cc)越大；而当第一上行载波的频率小于第一上行载波的频率时，alpha(cc)小于1，且两者的差值越大，alpha(cc)越小。

在本申请中，当终端设备采用第一上行载波，发送随机接入前导码时，所述powerRampingStep(cc)取值为第一路径损耗补偿因子，而终端设备采用第二上行载波，发送随机接入前导码时，所述所述powerRampingStep(cc)取值第二路径损耗补偿因子。
应当指出，上述公式(2)相对于现有技术中，计算上行信号发射功率的改进，主要在powerRampingStep(cc)；上述公式(2)中的PL为终端设备基于网络设备现有的第一下行载波(比如3.5G)，所计算的下行路径损耗；在本申请中，当终端设备采用第一上行载波F1发送随机接入前码码时，所述powerRampingStep(cc)的值与现有技术中计算上行路径损耗的值相同，假设该值为powerRampingStep(cc-F1)，所述第一上行载波与第一下行载波相匹配；而当终端设备采用第二上行载波F2发送随机接入前导码时，所述第二上行载波与第一下行载波不匹配，如果第二上行载波的频率F2小于第一上行载波的频率F1，那么此时powerRampingStep(cc_F2)的取值小于powerRampingStep(cc-F1)；如果第二上行载波的频率F2大于第一上行载波的频率F1，那么powerRampingStep(cc_F2)的取值大于powerRampingStep(cc-F1)。
第三种：图3所示的方法中的第一损耗参数为第一路径损耗调整因子，第二损耗参数为第一路径损耗调整因子，计算随机接入码的发射功率，符合下述公式：
PreambleReceivedTarget Power＝preambleInitialReceivedTargetPower+deltaPreamble+(preambleTransmissionConter-1)*powerRampingStep+delta(cc,PL)；
P_PRACH＝min{P_CMAX,PreambleReceivedTargetPower+PL}；公式(3)
其中，所述P_PRACH代表所述随机接入前导码的发射功率；所述P_CMAX代表所述终端设备的最大发射功率；所述PreambleReceivedTargetPower代表所述网络设备期望接收到所述随机接入前导码的功率；所述下行路损是基于第一下行载波上的参考信号测量得到，下行参考信号可以为小区参考信号CRS、信道状态参考信号CSI-RS、同步信号块SS-Block等等；所述preambleInitialReceivedTargetPower代表所述第一终端设备在当前随机接入过程中，所述网络设备期望所接收的第一个随机接入前导码的功率；所述deltaPreamble代表与所述随机接入前导码的类型相关的调整量；所述preambleTransmissionConter代表所述第一 终端设备在当前随机接入过程中，发送所述随机接入前导码的次数；所述powerRampingStep代表所述终端设备在当前随机接入过程中，相邻两次送所述随机接入前导码之间的功率攀升因子；所述delta(cc,PL)代表所述路径损耗调整因子。
在本申请中，当终端设备采用第一上行载波，发送随机接入前导码时，所述delta(cc,PL)取值为第一路径损耗调整因子，而终端设备采用第二上行载波，发送随机接入前导码时，所述所述delta(cc,PL)取值第二路径损耗调整因子。
应当指出，上述公式(3)相对于现有技术中，计算上行信号发射功率的改进，主要在delta(cc,PL)；上述公式(3)中的PL为终端设备基于网络设备现有的第一下行载波(比如3.5G)，所计算的下行路径损耗；当终端设备采用第一上行载波发送随机接入前导码时，所述delta(cc,PL)的值取0，所述第一上行载波与第一下行载波相匹配；当终端采用第二上行载波发送随机接入前导码时，所述delta(cc,PL)的值非零，所述二上行载波与所述第一下行载波不匹配，若所述第二上行载波的频率大于第一上行载波的频率，所述delta(cc,PL)大于0，且所述第二上行载波与所述第一上行载波频率间的差值越大，所述delta(cc,PL)的值越大；若所述第二上行载波的频率小于第一上行载波的频率，所述delta(cc,PL)小于0，且所述第二上行载波与所述第一上行载波频率间的差值越大，所述delta(cc,PL)的值越小。此外，终端基于第一下行载波测量得到的下行路损值越大，delta(cc,PL)的绝对值越大。比如当第一上行载波小于第二上行载波时，如表2所示，两者的差值越大，delta(cc,PL)的值越小。
基于第一下行载波的下行路损/dB delta(cc,PL)/dB

应当理解，在上述第一种示例的路径损耗补偿因子alpha(cc)、第二种示例中的功率攀升因子powerRampingStep(cc)以及第三种示例中的路径损耗调整因子delta(cc,PL)针对4G LTE应用场景中的相关名称；在未来的移动通信系统中，比如5G中，上述公式中跟载波相关的变量可有不同的名称，但会体现在相应的功率控制的公式中，因此应该都在本申请的保护范围内。
