Description

一种路损参考信号确定方法及相关装置
本申请要求于2021年12月30日提交中国专利局、申请号为2021116698102、申请名称为“一种路损参考信号确定方法及相关装置”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
本申请涉及通信技术领域，尤其涉及一种路损参考信号确定方法及相关装置。
背景技术
载波聚合(carrier aggregation，CA)，是指将多个载波聚合在一起为用户设备(user equipment，UE)提供服务。对UE来说，每个载波可以看成一个小区。这些聚合在一起的小区，可以分为主小区(primary cell，PCell)和辅小区(secondary cell，SCell)。UE接入网络时，首先接入主小区，然后由主小区通过无线资源控制(radio resource control，RRC)重配置消息为UE添加若干个辅小区，并激活这些辅小区，使得这些辅小区具备物理上行控制信道(physical uplink control channel，PUCCH)等其他上行信道的数据接收能力，UE后续可以接入被激活的辅小区进行通信，获得相应的服务。
目前，在上述辅小区激活过程中，需要根据路损参考信号计算下行路损，从而确定UE在上行信道的上行发送功率，完成辅小区的激活。
但是，目前确定上行信道的上行发送功率的准确率和效率较低，还可能产生额外的激活时延。
发明内容
本申请实施例提供了一种路损参考信号确定方法及相关装置，通过选择一个能较为真实的反映UE所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
第一方面，本申请实施例提供了一种路损参考信号确定方法，该方法包括：
终端设备接收网络设备发送的激活信息，所述激活信息用于指示第一小区被激活，所述第一小区为具备上行信道的数据接收能力的小区；
所述终端设备将目标参考信号确定为路损参考信号，所述目标参考信号包括用于反映所述终端设备对应的下行链路路损情况的参考信号，所述路损参考信号用于确定所述上行信道的上行发送功率。
本申请实施例中，提供了一种路损参考信号确定方法。具体为，终端设备接收网络设备发送的激活信息，指示第一小区被激活，该第一小区为具备终端设备对应的上行信道的数据接收能力的小区。在第一小区被激活的过程中，终端设备需要确定其对应的上行信道的上行发送功率，而确定上行信道的发送功率需要计算下行路损，因此，终端设备将目标参考信号确定为路损参考信号，其中，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号，该路损参考信号可以用于计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。此外，本申请实施例提供的将目标参考信号确定为路损参考信号的方法不仅适用于第一小区激活过程中，在第一小区完成激活后，且网络设备一直未配置路损 参考信号的情况下，依然可以采用本申请实施例提供的方法，将上述目标参考信号确定为路损参考信号。
目前，在终端设备没有配置用于进行下行信道路损估计的参数的情况下，终端设备通常获取主信息块(master information block，MIB)的同步信号块(synchronization signal block，SSB)作为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率。但是在第一小区的激活过程中，终端设备在收到激活信息后，并不一定需要读取第一小区的主信息块，因此，此时终端设备选择何种参考信号作为路损参考信号并不明确，可能导致终端设备确定的上行信道的上行发送功率不准确，或者，终端设备需要等待网络设备配置的路损参考信号，从而导致第一小区额外的激活时延。
而本申请实施例中，终端设备在接收到网络设备发送的激活信息之后，将用于反映终端设备对应的下行链路路损情况的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。

在所述第一小区对应的配置信息中不包括用于进行下行信道路损估计的第一参数的情况下，将所述目标参考信号确定为所述路损参考信号。
在本申请实施例中，提供了一种将目标参考信号确定为路损参考信号的可能的实施方式。具体为，在第一小区对应的配置信息中不包括第一参数的情况下，将上述目标参考信号确定为路损参考信号。其中，第一参数为用于进行下行信道路损估计的参数，目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号。与目前采用主信息块的同步信号块确定为路损参考信号的方式相比，本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一种可能的实施方式中，所述目标参考信号包括第一参考信号或第二参考信号或与所述第一参考信号具有准共址关系的参考信号或与所述第二参考信号具有准共址关系的参考信号；其中，所述第一参考信号为所述终端设备上报过的层3测量结果对应的参考信号，所述第二参考信号为所述终端设备上报过的层1测量结果对应的参考信号。
在本申请实施例中，提供了一种目标参考信号的可能的实施方式。具体为，目标参考信号可以包括但不限于第一参考信号或第二参考信号或与第一参考信号具有准共址关系的参考信号或与第二参考信号具有准共址关系的参考信号。其中，第一参考信号为终端设备上报过的层3测量结果对应的参考信号，第二参考信号为终端设备上报过的层1测量结果对应的参考信号。具体的，上述层3测量结果可以是层3参考信号接收功率(Layer 3 reference signal received power，L3-RSRP)，该第一参考信号可以是上报过的多个层3参考信号接收功率对应的参考信号中的任意一个，也可以是上报过的接收功率最高的层3参考信号接收功率对应的参考信号，还可以是指定时间段内上报的层3参考信号接收功率对应的参考信号，还可以是最新上报的层3参考信号接收功率对应的参考信号，此处不做限定，可根据具体的应用场景进行选择。上述层1测量结果可以是层1参考信号接收功率(Layer 1 reference signal received power，L1-RSRP)，第二参考信号的选择与第一参考信号的选择类似，此处不做限定，可根 据具体的应用场景进行选择。通过本申请实施例，在第一小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第一参考信号或与第一参考信号具有准共址关系的参考信号确定为路损参考信号，或者，将上述第二参考信号或与第二参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一种可能的实施方式中，所述第一小区为已知小区，所述目标参考信号包括所述第一参考信号或与所述第一参考信号具有准共址关系的参考信号；或者，
所述第一小区为未知小区，所述目标参考信号包括所述第二参考信号或与所述第二参考信号具有准共址关系的参考信号。
在本申请实施例中，提供了一种目标参考信号的可能的实施方式。具体为，根据第一小区是已知小区还是未知小区来决定目标参考信号包括第一参考信号或与第一参考信号具有准共址关系的参考信号，还是包括第二参考信号或与第二参考信号具有准共址关系的参考信号。其中，在收到激活信息时，如果终端设备之前已经上报过该小区的测量结果，则将该小区视为已知小区，否则视为未知小区。当第一小区为已知小区时，目标参考信号包括上述第一参考信号或与第一参考信号具有准共址关系的参考信号，此时，在第一小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第一参考信号或与第一参考信号具有准共址关系的参考信号确定为路损参考信号。当第一小区为未知小区时，目标参考信号包括上述第二参考信号或与第二参考信号具有准共址关系的参考信号，此时，在第一小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第二参考信号或与第二参考信号具有准共址关系的参考信号确定为路损参考信号。通过本申请实施例确定的目标参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。

在本申请实施例中，提供了一种目标参考信号的可能的实施方式。具体为，在第一小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，目标参考信号包括第五参考信号或与第五参考信号具有准共址关系的参考信号。其中，在第一小区被激活的过程中，终端设备需要选择一个同步信号与第一小区进行精确的定时同步，第五参考信号即为终端设备选择的用于与第一小区进行精确定时同步的同步信号。终端设备可以将上述第五参考信号或与第五参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。通过本申请实施例，终端设备选择用于对第一小区进行精确定时同步的同步信号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。

在本申请实施例中，提供了一种目标参考信号的可能的实施方式。具体为，在第一小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，且在第一小区的定时提前值失效的情况下，目标参考信号包括第六参考信号或与第六参考信号具有准共址关系的参考信号。其中，在第一小区的定时提前值失效的情况下，终端设备接收网络设备发送的下行信道指示信息，触发随机接入，并将该下行信道指示信息所指示的参考信号确定为上述第六参考信号。终端设备可以将上述第六参考信号或与第六参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。通过本申请实施例，终端设备选择用于触发随机接入的下行信道指示信息所指示的参考信号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
第二方面，本申请实施例提供了一种路损参考信号确定方法，该方法包括：
网络设备向终端设备发送激活信息，所述激活信息用于指示第一小区被激活，所述第一小区为具备上行信道的数据接收能力的小区；
所述网络设备接收所述终端设备发送的第一消息，所述第一消息的上行发送功率由路损参考信号确定，所述路损参考信号由目标参考信号确定，所述目标参考信号包括用于反映所述终端设备对应的下行链路路损情况的参考信号。
本申请实施例中，提供了一种路损参考信号确定方法。具体为，网络设备向终端设备发送激活信息，指示第一小区被激活，该第一小区为具备终端设备对应的上行信道的数据接收能力的小区。在终端设备接入被激活后的第一小区后，网络设备接收终端设备发送的第一消息。其中，终端设备在向网络设备发送第一消息之前，需要确定其对应的上行信道的上行发送功率，即第一消息的上行发送功率，而确定上行信道的发送功率需要计算下行路损，因此，第一消息的上行发送功率由路损参考信号确定，而路损参考信号可以由目标参考信号确定，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号，该路损参考信号可以用于计算下行路损，进而确定第一消息的上行发送功率，以实现网络设备成功接收第一消息。此外，本申请实施例提供的将目标参考信号确定为路损参考信号的方法不仅适用于第一小区激活过程中，在第一小区完成激活后，且网络设备一直未配置路损参考信号的情况下，依然可以采用本申请实施例提供的方法，将上述目标参考信号确定为路损参考信号。
目前，在终端设备没有配置用于进行下行信道路损估计的参数的情况下，路损参考信号通常由主信息块的同步信号块确定，计算下行路损，进而确定第一消息的上行发送功率。但是在第一小区的激活过程中，终端设备在收到网络设备发送的激活信息后，并不一定需要读取第一小区的主信息块，因此，此时路损参考信号由何种参考信号确定并不明确，可能导致确定的第一消息的上行发送功率不准确，从而导致网络设备无法成功接收第一消息，或者，需要等待网络设备为终端设备配置路损参考信号，从而导致第一小区额外的激活时延以及第一消息额外的接收时延。
而本申请实施例中，网络设备接收的第一消息的上行发送功率由路损参考信号确定，且该路损参考信号由目标参考信号确定，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号，以实现网络设备成功接收第一消息。本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定第一消息的上行发送功率的准确率和效率，消除第一小区额外的激活时延以及第一消息额外的接收时延。

在本申请实施例中，提供了一种目标参考信号的可能的实施方式。具体为，目标参考信号可以包括但不限于第一参考信号或第二参考信号或与第一参考信号具有准共址关系的参考信号或与第二参考信号具有准共址关系的参考信号。其中，第一参考信号为终端设备上报过的层3测量结果对应的参考信号，第二参考信号为终端设备上报过的层1测量结果对应的参考信号。具体的，上述层3测量结果可以是层3参考信号接收功率，该第一参考信号可以是上报过的多个层3参考信号接收功率对应的参考信号中的任意一个，也可以是上报过的接收功率最高的层3参考信号接收功率对应的参考信号，还可以是指定时间段内上报的层3参考信号接收功率对应的参考信号，还可以是最新上报的层3参考信号接收功率对应的参考信号，此处不做限定，可根据具体的应用场景进行选择。上述层1测量结果可以是层1参考信号接收功率，第二参考信号的选择与第一参考信号的选择类似，此处不做限定，可根据具体的应用场景进行选择。通过本申请实施例，在第一小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，路损参考信号可以由上述第一参考信号或与第一参考信号具有准共址关系的参考信号确定，或者，路损参考信号可以由上述第二参考信号或与第二参考信号具有准共址关系的参考信号确定，计算下行路损，进而确定第一消息的上行发送功率，以实现网络设备成功接收第一消息。本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定第一消息的上行发送功率的准确率和效率，消除第一小区额外的激活时延以及第一消息额外的接收时延。

本申请实施例提供的技术方案可以应用于各种通信系统，例如，卫星通信系统，卫星通信与蜂窝网络融合的系统。其中，蜂窝网络系统可以包括但不限于：第五代(5th generation，5G)系统、全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新空口(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTEbased access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如：设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及未来演进的其他通信系统等其他新的系统，本申请实施例也可以应用于这些通信系统。卫星通信系统可以包括各种非陆地网络系统，例如，卫星或无人机系统(unmanned aircraft system，UAS)平台等进行无线频率发射的网络，此处不再一一列举。
下面结合本申请实施例中的附图对本申请实施例进行描述。
示例性的，本申请实施例应用的通信系统100可参阅图1，图1为本申请实施例提供的一种通信系统的架构示意图。
如图1所示，该通信系统100主要包括接入网和用户设备(user equipment，UE)101两部分。其中，接入网用于实现无线接入有关的功能，主要包括接入网络(access network，AN)设备102，接入网络设备包括了无线接入网络(radio access network，RAN)设备以及其它通过空口接入的设备(比如WiFi)。各网元之间的接口如图1中所示。应理解，网元之 间还可以采用服务化接口进行通信。
UE，也可以称为终端设备。终端设备可以经AN设备与一个或多个核心网(core network，CN)进行通信。本申请实施例中涉及的终端设备包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接网络；和/或经由无线接口，如：针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如手持数字电视广播(Digital Video Broadcast-Handheld，DVB-H)网络的数字电视网络、卫星网络、调幅-调频(Amplitude Modulation-Frequency Modulation，AM-FM)广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。该终端设备的示例包括但不限于卫星电话或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历和/或全球定位系统(Global Positioning System，GPS)接收器的个人数字助理(personal digital assistant，PDA)；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、物联网或车联网中的终端设备、5G网络中的终端设备、未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备以及未来网络中的任意形态的终端设备等。
AN设备，是一种将终端设备接入到无线网络的设备，具体可以为基站。基站可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。具体可以为：无线局域网(wireless local area network，WLAN)中的接入点(access point，AP)，全球移动通信系统(global system for mobile communications，GSM)或码分多址接入(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolved Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及5G系统中的下一代节点B(the next generation Node B，gNB)或者未来演进的公用陆地移动网(public land mobile network，PLMN)网络中的基站等，本申请实施例对此不作具体限定。
由图1可以看出，通信系统100应用于载波聚合(Carrier Aggregation，CA)场景中，载波聚合指的是将多个载波聚合在一起为UE提供服务，可以提高通信系统的数据传输容量。对UE来说，每个载波可以看成一个小区。接入网络设备102覆盖了多个小区(主小区、辅小区1、辅小区2、….、辅小区n)，这些聚合在一起的小区，可以分为主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)。UE接入网络时，首先接入主小区，然后由主小区通过RRC重配置消息为UE添加若干个辅小区(如辅小区1、辅小区2、…、辅小区n)，使得UE后续可以接入辅小区进行通信，获得相应的服务。
对于添加的辅小区，主小区可以将其配置为激活(activated)态或者去激活(deactivated) 态。主小区通过辅小区激活和去激活的媒体接入控制的控制元素(Medium Access Control-Control Element，MAC CE)来调整每个辅小区的状态。当某个辅小区处于激活态时，UE可以在该辅小区上发送探测参考信号(Sounding Reference Signal，SRS)、上报信道状态信息(Channel State Information，CSI)、检测物理下行控制信道(Physical Downlink Control Channel，PDCCH)等。当某个辅小区处于去激活态时，UE在该辅小区上不发送SRS、不测量和上报CSI、不传输上行数据、不检测PDCCH。
图1中的多个小区部署在同一个接入网络设备102中，这种部署方式也称为站内(intra-site)载波聚合。站内载波聚合场景中，各个小区之间的数据传输可以理解为是接入网络设备102中与各个小区对应的各个不同网元(功能模块)之间的数据传输。
应理解，本申请实施例并不限定只应用于图1所示的通信系统架构中。例如，可以应用本申请实施例的路损参考信号确定方法的通信系统中可以包括更多或更少的网元或设备。图1中的设备或网元可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。图1中的设备或网元之间可以通过其他设备或网元通信。
示例性的，本申请实施例应用的通信系统200可参阅图2，图2为本申请实施例提供的另一种通信系统的架构示意图。
如图2所示，该通信系统200主要包括接入网和用户设备(user equipment，UE)101两部分。其中，接入网用于实现无线接入有关的功能，主要包括接入网络(access network，AN)设备(102、103、104、105)，接入网络设备包括了无线接入网络(radio access network，RAN)设备以及其它通过空口接入的设备(比如WiFi)。各网元之间的接口如图2中所示。应理解，网元之间还可以采用服务化接口进行通信。
本申请实施例所示的通信系统中的UE和AN设备与上述图1中的通信系统类似，此处不再赘述。
由图2可以看出，通信系统200应用于载波聚合(Carrier Aggregation，CA)场景中，可以提高通信系统的数据传输容量，不同于上述图1所示的通信系统的载波聚合场景，本申请实施例中的多个小区分别部署在不同的接入网络设备中，如主小区部署在接入网络设备102中，辅小区1部署在接入网络设备103中，辅小区2部署在接入网络设备104中，辅小区n部署在接入网络设备105中。这种部署方式也称为站间(inter-site)载波聚合。站间载波聚合场景中，各个小区之间的数据传输可以理解为是与各个小区对应的各个不同接入网络设备之间的数据传输。UE接入网络时，首先接入主小区，然后由主小区通过RRC重配置消息为UE添加若干个辅小区(如辅小区1、辅小区2、…、辅小区n)，使得UE后续可以接入辅小区进行通信，获得相应的服务。
应理解，本申请实施例并不限定只应用于图2所示的通信系统架构中。例如，可以应用本申请实施例的路损参考信号确定方法的通信系统中可以包括更多或更少的网元或设备。图2中的设备或网元可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。图2中的设备或网元之间可以通过其他设备或网元通信。
基于上述图1或图2中的通信系统所应用的载波聚合场景，UE接入网络时，首先接入主小区，然后由主小区通过RRC重配置消息为UE添加若干个辅小区(如辅小区1、辅小区2、…、辅小区n)，使得UE后续可以接入辅小区进行数据传输，获得相应的服务。
为了UE能够顺利接入辅小区进行数据传输，UE还需要和接入的辅小区进行上行同步或下行同步。下面将对UE与辅小区之间的上行同步、下行同步进行简单说明。
由于小区内不同的UE与网络设备(网元)之间的距离不同，因此，不同UE的上行信号 到达网络设备的时间也有所差异。这种差异会导致小区内不同UE的上行信号之间互相产生干扰。为了减少这种干扰，应该使得小区内不同UE的上行信号到达网络设备的时刻尽量对齐。通常采用上行定时提前(Timing Advance，TA)机制来实现网络设备侧接收到上行信号的时间同步，即UE与辅小区之间的上行同步。
其中，TA的原理是，给UE配置一个定时提前量(即TA值)，UE发送上行数据时按照配置的TA值调整上行定时。通过合理配置不同UE的TA值，可以实现不同UE的上行信号到达网络设备的时刻大致相同。此外，网络设备通过测量UE发送的前导信号(preamble)或者探测参考信号(Sounding Reference Signal，SRS)等上行信号，可以计算出UE的TA值。网络设备向UE发送定时提前指令(Timing Advance Command，TAC)，将计算出的TA值告知UE。TAC可以承载于MAC CE中。
下行同步，是指UE侧的同步，即UE获得网络设备的定时和频率等同步。UE通过接收网络设备发送的同步信号来实现下行同步。该同步信号包括主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)，承载于同步信号块(Synchronization Signal Block，SSB)中。小区通常周期性发送SSB，UE搜索并接收SSB以获得与辅小区之间的下行同步。
此外，在通过RRC重配置消息为UE添加若干个辅小区之后，还需要通过MAC信令来激活这些辅小区，使得这些辅小区具备数据收发的能力。现有协议对辅小区激活时延的规定为，终端设备在接收到辅小区的激活信息后，需要反馈对应的混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)，然后进行激活过程，并反馈CSI，表示该辅小区完成了激活过程。使得UE后续可以接入被激活的辅小区进行数据传输，获得相应的服务。
其中，辅小区的激活过程包括多个步骤，对于频率范围1(Frequency Range 1，FR1)的辅小区，该激活过程包括小区搜索、自动增益控制(automatic gain control，AGC)、定时同步等过程。而对于频率范围2(Frequency Range 2，FR2)的辅小区，由于涉及波束信息，该激活过程需要包括更多步骤，比如，还包括用于CSI上报的信道状态信息的参考信号(channel state information-reference signal，CSI-RS)激活的时间、配置传输配置指示(Transmission Configuration Indicator，TCI)的时间，以及如果待激活的辅小区是未知小区，UE还需要进行层1参考信号接收功率(Layer 1 reference signal received power，L1-RSRP)测量并上报，告诉网络波束信息。目前，对于未配置上行信道的辅小区，在完成HARQ反馈、激活步骤后，即可在对应的PUCCH反馈CSI信息，表示该辅小区激活完成。对于配置了上行信道的辅小区，还需要考虑以下步骤：确定上行信道的上行发送功率、确定上行发送波束、更新TA(如果TA失效)。
更新TA的方式可以为：在辅小区所在的定时提前量组(Timing Advance Group，TAG)对应的TA值已经过期的情况下，即此时与网络设备的上行同步已经过期，UE无法直接发送上行数据，需要重新获得上行同步后再进行发送。具体可以通过接收网络设备发送的物理下行控制信道指示信息来触发UE随机接入，UE通过发起随机接入过程，更新有效TA，从而具备上行数据发送能力。其中，物理下行控制信道指示信息中还需要明确指示所关联的同步信号块(synchronization signal block，SSB)。
确定上行信道的上行发送功率的方式可以为：UE计算下行路损，具体可以通过获取网络侧发送的信道的功率以及对路损参考信号(pathloss reference signals，PL-RS)测得的功率计算得到下行路损。其中，在不同的应用场景下，可以选择不同的参考信号作为用于计算下行路损的路损参考信号，由此计算得到的下行路损以及上行信道的上行发送功率也会不同。
根据现有协议的规定，主要可以根据网络侧对辅小区是否配置了第一参数以及第二参数，分为四种不同的情况，并在各个情况下选择不同的参考信号作为路损参考信号。其中，第一参数是网络侧配置的一组用来进行上行信道路损估计的参数，第二参数是网络侧配置的一组用来确定上行信道的空间关系和功率控制的参数。具体情况如下：
一、如果辅小区对应的配置信息中没有配置上述第一参数，则UE选择获取主信息块(master information block，MIB)的同步信号块(synchronization signal block，SSB)作为路损参考信号；
二、如果辅小区对应的配置信息中配置了上述第一参数以及第二参数，则UE通过上述第二参数的指示确定路损参考信号，比如，第二参数确定的上行信道的空间关系会指示用于确定上行空间关系的参考信号，也会支持路损参考信号的标识ID；
三、如果辅小区对应的配置信息中配置了上述第一参数，但未配置上述第二参数，则UE选择上述第一参数中配置的索引(index)为0的参考信号作为路损参考信号；
四、如果辅小区对应的配置信息中没有配置上述第一参数和第二参数，且网络侧配置了第三参数(enableDefaultBeamPL-forPUCCH)，此时，UE选择当前下行带宽的控制资源集的传输配置指示信息(control-resource set，CORESET)所指示的参考信号作为路损参考信号。
在上述第一种情况下，如果辅小区对应的配置信息中没有配置上述第一参数，则UE选择获取MI B的同步信号块作为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率。但是，在辅小区被激活的过程中，UE在收到激活信息后，并不一定需要读取该辅小区的主信息块。因此，此时UE选择何种参考信号作为路损参考信号并不明确，可能导致UE确定的上行信道的上行发送功率不准确，或者，UE需要等待网络侧配置的路损参考信号，从而导致辅小区额外的激活时延。
针对上述确定上行信道的上行发送功率的准确率和效率较低，还可能产生额外的激活时延的技术问题，本申请提供了一种路损参考信号确定方法及相关装置，涉及通信技术领域，明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
请参阅图3，图3为本申请实施例提供的一种路损参考信号确定方法的流程示意图，该路损参考信号确定方法应用于通信技术领域。
如图3所示，本申请实施例的路损参考信号确定方法应用的通信系统包括但不限于终端设备、网络设备。
如图3所示，本申请实施例的路损参考信号确定方法可以包括步骤S301、S302以及S303，其中，步骤S301、S302以及S303的执行顺序，本申请实施例对此不作限制，具体的，该路损参考信号确定方法包括但不限于如下步骤：
步骤S301：终端设备接收网络设备发送的激活信息，相应的，网络设备向终端设备发送激活信息。
其中，该激活信息用于指示第一小区被激活，该第一小区为配置了上行信道的小区。该第一小区具体可以是上述图1或图2中的辅小区1、辅小区2、…、辅小区n。该上行信道可以包括但不限于终端设备对应的物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)等上行信道。
本申请实施例中的网络设备为第一小区对应的网络设备，具体可以是上述图1中的网络 设备102。具体的，终端设备当前接入的主小区与第一小区所表示的辅小区部署在同一个网络设备(如基站)上时，本申请实施例中的网络设备还可以是第一小区与主小区对应的网络设备。本申请实施例中的终端设备为搭载了可用于执行计算机执行指令的处理器的设备，具体可以是如计算机、手机之类的终端设备等，具体还可以是上述图1或图2中的终端设备101，用于通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
需要注意的是，在本申请实施例中，以上述图1所示的站内载波聚合场景为例进行说明，即终端设备当前接入的主小区与第一小区所表示的辅小区部署在同一个网络设备(如基站)上，本申请实施例中的网络设备为第一小区与主小区对应的网络设备。具体的，终端设备当前接入的主小区可以对应于图1所示的主小区，本申请实施例中的第一小区可以对应于图1所示的辅小区1、辅小区2、…、辅小区n中的任意一个辅小区。相应的，本申请实施例中的网络设备可以对应于上述图1中的网络设备102，本申请实施例中的终端设备可以对应于上述图1中的终端设备101。
步骤S302：终端设备将目标参考信号确定为路损参考信号。
在接收到网络设备发送的激活信息后，表示辅小区处于被激活过程中。在辅小区的激活过程中，终端设备需要反馈对应的HARQ消息，然后进行辅小区激活，并反馈CSI，表示该辅小区完成了激活过程，使得终端设备后续可以与被激活的辅小区进行数据传输，获得相应的服务。
在本申请实施例中配置了上行信道的辅小区的激活过程中，比如，在配置了PUCCH的辅小区的激活过程中，终端设备还需要确定上行信道的上行发送功率。具体可以通过获取网络侧发送的信道的功率以及对路损参考信号测得的功率，计算得到下行路损，进而根据下行路损确定上行信道的上行发送功率。其中，在不同的应用场景下，可以选择不同的参考信号作为用于计算下行路损的路损参考信号，由此计算得到的下行路损以及上行信道的上行发送功率也会不同。
根据现有协议的规定，如果辅小区对应的配置信息中没有配置用来进行上行信道路损估计的参数，则终端设备选择获取MIB的同步信号块作为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率。
但是，在辅小区被激活的过程中，终端设备在收到激活信息后，并不一定需要读取该辅小区的主信息块。因此，此时终端设备选择何种参考信号作为路损参考信号并不明确，可能导致终端设备确定的上行信道的上行发送功率不准确，或者，终端设备需要等待网络侧配置的路损参考信号，从而导致辅小区额外的激活时延。
针对上述确定上行信道的上行发送功率的准确率和效率较低，还可能产生额外的激活时延的技术问题，在本步骤中，终端设备将目标参考信号确定为路损参考信号，其中，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号。通过将用于反映终端设备对应的下行链路路损情况的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成辅小区的激活。
此外，本步骤提供的将目标参考信号确定为路损参考信号的方法不仅适用于上述辅小区激活过程中，在辅小区完成激活后，依然可以采用本步骤提供的方法，将上述目标参考信号确定为路损参考信号。例如，在完成辅小区激活后，且网络设备也一直未配置路损参考信号的情况下，也可以按照本步骤的方法，将上述目标参考信号确定为路损参考信号，可以准确 计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率。
与现有协议的规定相比，本步骤明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
具体的，在辅小区对应的配置信息中没有配置用来进行上行信道路损估计的参数的情况下，终端设备将目标参考信号确定为路损参考信号，其中，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号。
在一些可能的实施例中，目标参考信号可以包括但不限于第一参考信号或第二参考信号或与第一参考信号具有准共址(quasi-colocation，QCL)关系的参考信号或与第二参考信号具有准共址关系的参考信号。
其中，第一参考信号为终端设备上报过的层3测量结果对应的参考信号，第二参考信号为终端设备上报过的层1测量结果对应的参考信号。
具体的，上述层3测量结果可以是层3参考信号接收功率(Layer 3 reference signal received power，L3-RSRP)，该第一参考信号可以是上报过的多个层3参考信号接收功率对应的参考信号中的任意一个，也可以是上报过的接收功率最高的层3参考信号接收功率对应的参考信号，还可以是指定时间段内上报的层3参考信号接收功率对应的参考信号，还可以是最新上报的层3参考信号接收功率对应的参考信号，此处不做限定，可根据具体的应用场景进行选择。
上述层1测量结果可以是层1参考信号接收功率(Layer 1 reference signal received power，L1-RSRP)，第二参考信号的选择与第一参考信号的选择类似，该第二参考信号可以是上报过的多个层1参考信号接收功率对应的参考信号中的任意一个，也可以是上报过的接收功率最高的层1参考信号接收功率对应的参考信号，还可以是指定时间段内上报的层1参考信号接收功率对应的参考信号，还可以是最新上报的层1参考信号接收功率对应的参考信号，此处不做限定，可根据具体的应用场景进行选择。
在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第一参考信号或与第一参考信号具有准共址关系的参考信号确定为路损参考信号，或者，将上述第二参考信号或与第二参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。
进一步地，可以根据辅小区是已知小区还是未知小区来决定目标参考信号包括第一参考信号或与第一参考信号具有准共址关系的参考信号，还是包括第二参考信号或与第二参考信号具有准共址关系的参考信号。
其中，在收到激活信息时，如果终端设备之前已经上报过该小区的测量结果，则将该小区视为已知小区，否则视为未知小区。
具体的，当辅小区为已知小区时，目标参考信号包括上述第一参考信号或与第一参考信号具有准共址关系的参考信号。此时，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第一参考信号或与第一参考信号具有准共址关系的参考信号确定为路损参考信号。
当辅小区为未知小区时，目标参考信号包括上述第二参考信号或与第二参考信号具有准 共址关系的参考信号。此时，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第二参考信号或与第二参考信号具有准共址关系的参考信号确定为路损参考信号。
可选的，当终端设备上报了层1参考信号接收功率或层3参考信号接收功率后，网络侧可以通过信令指示其中一个对应的参考信号作为路损参考信号。其中，该信令可以是RRC信令、MAC信令、DCI信令等。
可选的，网络侧可以在激活辅小区的信令中同时指示终端设备选择一个对应的参考信号作为路损参考信号，也可以通过单独的信令指示终端设备选择一个对应的参考信号作为路损参考信号。
本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一些可能的实施例中，目标参考信号包括第三参考信号或与第三参考信号具有准共址关系的参考信号。
其中，第三参考信号为上行信道的空间关系所指示的参考信号，如同步信号块、信道状态信息的参考信号、探测参考信号等。
具体的，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第三参考信号或与第三参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。
本申请实施例中，终端设备选择网络设备配置的上行信道的空间关系所指示的参考信号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，并且可以通过上行信道的空间关系所指示发送方向对应的路损确定上行信道的上行发送功率，此种方式下，终端设备与网络设备可以对下行路损建立一致理解，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一些可能的实施例中，目标参考信号包括第四参考信号或与第四参考信号具有准共址关系的参考信号。
其中，第四参考信号为当前下行带宽的控制资源集的传输配置指示信息所指示的参考信号。
具体的，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第四参考信号或与第四参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。
本申请实施例中，终端设备选择网络设备配置的控制资源集的传输配置指示信息所指示的参考信号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，并且可以与网络设备对下行路损建立一致理解，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一些可能的实施例中，目标参考信号包括第五参考信号或与第五参考信号具有准共址关系的参考信号。
其中，在辅小区被激活的过程中，终端设备需要选择一个同步信号与辅小区进行精确的定时同步，第五参考信号即为终端设备选择的用于与辅小区进行精确定时同步的同步信号。
具体的，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，终端设备可以将上述第五参考信号或与第五参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。
本申请实施例中，终端设备选择用于对辅小区进行精确定时同步的同步信号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一些可能的实施例中，目标参考信号包括第六参考信号或与第六参考信号具有准共址关系的参考信号。
其中，在辅小区的定时提前值失效的情况下，终端设备接收网络设备发送的下行信道指示信息，触发随机接入，并将该下行信道指示信息所指示的参考信号确定为上述第六参考信号。
具体的，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，且在辅小区的定时提前值失效的情况下，终端设备可以将上述第六参考信号或与第六参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。
本申请实施例中，终端设备选择用于触发随机接入的下行信道指示信息所指示的参考信号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
在一些可能的实施例中，可以规定在激活配置了上行信道的辅小区时，比如，在激活配置了PUCCH的辅小区时，网络侧一定要配置路损参考信号，即排除了具备PUCCH数据接收能力的辅小区没有配置路损参考信号的情况。
此时，终端设备可以直接根据网络侧配置的路损参考信号准确计算下行路损，大大提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
可以理解的是，在上述多种可能的实施例中，选择何种参考信号作为目标参考信号，进而确定路损参考信号，将直接影响到计算下行路损的准确性，以及确定上行信道的上行发送功率的准确性。因此，在不同的应用场景中，需要基于能较为真实的反映终端设备所对应的下行链路路损情况的原则去选择合适的参考信号作为目标参考信号，进而确定路损参考信号，即应当基于提高计算下行路损的准确性，以及提高确定上行信道的上行发送功率的准确性的原则确定路损参考信号，而不应当仅以上述提供的有限个实施例对在不同的应用场景中确定路损参考信号构成限定。
比如，在辅小区对应的配置信息中不包括用于进行下行信道路损估计的参数的情况下，且在辅小区的定时提前值失效的情况下，可以按照上述实施例中的方法，将上述第六参考信号或与第六参考信号具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活；
也可以根据该辅小区是已知小区还是未知小区来决定选择何种参考信号作为路损参考信号，当该辅小区为已知小区时，将终端设备上报过的层3测量结果(比如，上报过的层3参考信号接收功率)对应的参考信号或与其具有准共址关系的参考信号作为路损参考信号，当该辅小区为未知小区时，将终端设备上报过的层1测量结果(比如，上报过的层1参考信号接收功率)对应的参考信号或与其具有准共址关系的参考信号作为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活；
还可以将上行信道的空间关系所指示的参考信号或与其具有准共址关系的参考信号作为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活；
还可以将当前下行带宽的控制资源集的传输配置指示信息所指示的参考信号或与其具有准共址关系的参考信号作为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活；
还可以将上述终端设备选择的用于与该辅小区进行精确定时同步的同步信号或与其具有准共址关系的参考信号确定为路损参考信号，计算下行路损，进而确定上行信道的上行发送功率，以完成第一小区的激活。
具体采用何种方式确定路损参考信号可以根据不同的需要进行调整，应以提高计算下行路损的准确性，以及提高确定上行信道的上行发送功率的准确性的结果为导向来确定最终的路损参考信号。
步骤S303：终端设备向网络设备发送第一消息，相应的，网络设备接收终端设备发送的第一消息。
在终端设备确定路损参考信号，计算下行路损，进而确定上行信道的上行发送功率之后，辅小区完成激活过程。在终端设备接入被激活后的辅小区后，终端设备向网络设备发送第一消息，该第一消息为上行消息，相应的，网络设备接收终端设备发送的第一消息。
其中，终端设备发送第一消息的发送功率即为上述根据路损参考信号确定上行信道的上行发送功率。因此，第一消息的上行发送功率由路损参考信号确定，而路损参考信号可以由目标参考信号确定，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号，该路损参考信号可以用于计算下行路损，进而确定第一消息的上行发送功率，以实现网络设备成功接收第一消息。
目前，在终端设备没有配置用于进行下行信道路损估计的参数的情况下，路损参考信号通常由主信息块的同步信号块确定，计算下行路损，进而确定第一消息的上行发送功率。但是在辅小区的激活过程中，终端设备在收到网络设备发送的激活信息后，并不一定需要读取辅小区的主信息块，因此，此时路损参考信号由何种参考信号确定并不明确，可能导致确定的第一消息的上行发送功率不准确，从而导致网络设备无法成功接收第一消息，或者，需要等待网络设备为终端设备配置路损参考信号，从而导致辅小区额外的激活时延以及第一消息额外的接收时延。
而本申请实施例中，网络设备接收的第一消息的上行发送功率由路损参考信号确定，且该路损参考信号由目标参考信号确定，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号，以实现网络设备成功接收第一消息。本申请实施例明确规定了采用何种参考信号作为路损参考信号，通过选择一个能较为真实的反映终端设备所对应的下行链路路损情况的参考信号作为路损参考信号，可以准确计算下行路损，从而提高确定第一消息的上行发送功率的准确率和效率，消除辅小区额外的激活时延以及第一消息额外的接收时延。

本申请实施例中，终端设备选择用于触发随机接入的下行信道指示信息所指示的参考信 号或与其具有准共址关系的参考信号作为路损参考信号，能较为真实的反映终端设备所对应的下行链路路损情况，从而准确计算下行路损，提高确定上行信道的上行发送功率的准确率和效率，消除额外的激活时延。
步骤S404：终端设备向网络设备发送第一消息，相应的，网络设备接收终端设备发送的第一消息。
在终端设备确定路损参考信号，计算下行路损，进而确定上行信道的上行发送功率之后，辅小区完成激活过程。在终端设备接入被激活后的辅小区后，终端设备向网络设备发送第一消息，该第一消息为上行消息，相应的，网络设备接收终端设备发送的第一消息。
其中，终端设备发送第一消息的发送功率即为上述根据路损参考信号确定上行信道的上行发送功率。因此，第一消息的上行发送功率由路损参考信号确定，而路损参考信号可以由目标参考信号确定，该目标参考信号包括用于反映终端设备对应的下行链路路损情况的参考信号，该路损参考信号可以用于计算下行路损，进而确定第一消息的上行发送功率，以实现网络设备成功接收第一消息。

在本申请所提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
所述功能如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器ROM、随机存取存储器RAM、磁碟或者光盘等各种可以存储程序代码的介质。
