具体实施方式
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。
本申请实施例提供的配置参数的方式可以适用于长期演进(long term evolution，LTE)系统，或其他采用各种无线接入技术的无线通信系统，例如采用码分多址(code division multiple access，CDMA)，频分多址(frequency division multiple access，FDMA)，时分多址(time division multiple access，TDMA)，正交频分多址(orthogonal frequency division multiple access，OFDMA)，单载波频分多址(single carrier-frequency division multiple access，SC-FDMA)等接入技术的系统，还适用于后续的演进系统，如上述5G系统(或称NR系统)等。参见图2，是本申请实施例提供的通信系统的一种基础架构。基站和终端设备通过无线接口可以进行数据或者信令的传输，包括上行传输和下行传输。本申请所涉及到的终端设备可以为向用户提供语音和/或数据连通性的设备(device)，包括有线终端和无线终端。无线终端可以是具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备，经无线接入网与一个或多个核心网进行通信的移动终端。例如，无线终端可以为移动电话、计算机、平板电脑、个人数码助理(personal digital assistant，PDA)、移动互联网设备(mobile Internet device，MID)、可穿戴设备和电子书阅读器(e-book reader)等。又如，无线终端也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动设备。再如，无线终端可以为移动站(mobile station)、接入点(access point)。用户设备(user equipment，UE)即为终端设备的一种，是在LTE系统中的称谓。为方便描述，本申请后续的描述中，上面提到的设备将以终端设备为例进行说明。本申请实施例所涉及到的基站是一种部署在无线接入网(radio access network,RAN)中用以为终端设备提供无线通信功能的装置。上述基站可以包括各种形式的宏基站，微基站，中继站，接入点基站控制器，收发节点(transmission reception point,TRP)等等。在采用不同的无线接入技术的系统中，基站的具体名称可能会有所不同，例如在LTE网络中，称为演进的节点B(evolved NodeB,eNB),在后续的演进系统中，还可以称为新无线节点B(new radio nodeB,gNB)。为方便描述，本申请后续的描述中，上面提到的设备统称为基站。
本申请实施例所要解决的技术问题是基于上述图2所示的系统架构，在基于波束(beam)对上行功率进行控制时，基站如何配置上行功率的功率控制参数以及如何指示终端设备配置的功率控制参数进行描述。
本申请实施例提供的方法所配置的参数具体可为上行功率控制的功率控制参数。本申请实施例提供的功率控制参数可包括路损补偿因子Alpha、闭环功率控制参数delta、基站侧期望接收到的信号功率P0。下面将简要介绍一下以上功率控制参数：
1、路损补偿因子Alpha(可记为α，以下将以Alpha进行描述)：
路损补偿因子乘以下行链路路损估计值PL用于补偿上行链路在传输过程中的功率损耗。其中，Alpha小于1时为部分路损补偿，Alpha等于1时为全路损补偿。
2、闭环功率控制参数delta(可记为Δ，以下将以delta进行描述)：
基站侧下发的动态指示终端设备的上行功率调整值，由下行控制信息(downlink control information，DCI)中的相应的字段指示。
3、基站侧期望接收到的信号功率P0(以下简称P0)：
基站侧期望接收到的信号功率P0基于上行噪声或者干扰水平确定，P0值反映了平均 的干扰水平，或相对固定的噪声水平。
开环参数为基站配置并下发给终端设备的参数，不需要终端设备反馈。开环参数的更新周期较大，开环参数可通过无线资源控制(radio resource control，RRC)信令或者系统消息下发给终端设备。闭环参数为基站配置并下发给终端设备，需要根据终端设备的反馈信息或上行信道的测量进行调整的参数。闭环参数的更新周期较小，可通过DCI通知终端设备。
在一些可行的实施方式中，上述功率控制参数中基站侧期望接收到的信号功率P0和路损补偿因子Alpha可以为开环参数，上述闭环功率控制参数delta可以为闭环参数。
目前，在NR的第三代合作伙伴项目(3rdgeneration partnership project，3GPP)提案讨论已提出的波束特定(beam-specific)的功率控制方案主要包括：
方案一：开环参数和闭环参数都可以基于波束对链路(beam pair link，BPL)来配置。然而这样子配置开环参数和闭环参数所消耗的信令开销大，适用性低。
方案二：开环参数和闭环参数都可以基于波束(beam)来配置。该方案未考虑基站侧接收波束的增益。
在上述技术方案中，基于BPL的功率控制参数配置是每个BPL配置一套开环参数或者闭环参数，或者每个BPL配置一套开环参数。由于基站与终端设备之间可能存在多条BPL，因此，每个BPL配置一套功率控制参数将带来较大的信令开销。此外，在基站与终端设备之间的BPL中，不同的BPL可能会具有相同的开环参数配置，不需要针对每个BPL配置一次开环参数，上述方案将带来参数配置的信令资源浪费。
下面将结合图3至图8对本申请实施例提供的配置参数的方法及装置进行描述。本申请实施例提供的方法包括对基站与终端设备之间的BPL的开环参数和/或闭环参数进行配置，通过BPL的功率控制参数配置实现对BPL的上行功率的控制。
参见图3，是本申请实施例提供的配置参数的方法的一实施例流程示意图。本申请实施例提供的配置参数的方法包括步骤：
S301，基站配置功率控制参数。
在一些可行的实施方式中，基站可基于基站与终端设备之间的波束测量结果划分BPL集合。其中，上述基站与终端设备之间包括N个BPL，N为大于或者等于2的整数。如图4，是本申请实施例提供的BPL示意图。其中，上述基站的收波束与终端设备的发波束建立的BPL的对应关系包括：终端设备的一个发波束对应基站的一个收波束，或者终端设备的一个发波束对应基站的多个收波束(即至少两个波束)，或者终端设备的多个发波束对应基站的多个收波束等。例如，终端设备侧的一个发波束对应基站侧的三个收波束，或者基站侧的一个收波束对应终端设备侧的两个发波束等。
在一些可行的实施方式中，基站可根据上述波束测量结果，将终端设备与基站之间的N个BPL划分为多个BPL集合(BPL group)，并以集合标识(group identity，group ID)或者集合索引(group index)等显式指示的方式对各个BPL集合进行指示，所述显示指示的方式可以是通过消息或者信令的形式向终端设备进行指示，或者通过与BPL相关联的准共址(quasi co-located，QCL)参数等指示信息隐式表示不同的BPL group。
可选的，在一些可行的实施方式中，基站可根据波束测量结果中的测量指标值对基站 与终端设备之间的BPL划分BPL集合。例如，基站可将测量指标值相近的BPL划分在同一个BPL集合，测量指标值差值较大的BPL划分在不同的BPL集合等，在此不做限制。
具体实现中，基站还可通过信令下发指示信息，其中，该指示信息用于通知终端设备上述BPL集合的分组结果。其中，上述信令可包括RRC信令、系统信息、DCI以及MAC CE等。上述信令仅是举例，而非穷举，具体可根据实际应用场景需求确定，在此不做限制。上述分组结果中可包括每个BPL集合中包括的基站与终端设备之间的BPL的对应关系，如下表1所示。表1为基站与终端设备之间的BPL分组结果的一示意表；
表1
Figure PCTCN2018084378-appb-000001
如上表1所示，BPLgroup0中可包括3个BPL，分别是TX beam1与RX beam1、TXbeam1与RX beam2，以及TX beam1与RX beam3。BPLgroup1中可包括2个BPL，分别是TX beam2与RX beam4和TXbeam3与RX beam4。BPLgroup2中可包括4个BPL，分别是TX beam4与RX beam5、TXbeam4与RX beam6，TXbeam5与RX beam5，以及TX beam5与RX beam6。
在一些可行的实施方式中，基站将基站与终端设备之间的BPL进行分组之后，可基于BPL集合配置第一类型参数。在本申请实施例中，基于BPL集合配置的参数可称为第一类型参数。具体的可配置每个BPL集合对应的第一类型参数。其中，分组为同一个BPL集合的所有BPL使用相同的第一类型参数，即，同一个BPL集合中的每个BPL使用相同的第一类型参数。例如，BPLgroup0中的3个BPL均使用相同的第一类型参数，无需每个BPL单独配置第一类型参数，节省了配置第一类型参数的信令开销。需要说明的是，第一类型参数可包括alpha，delta以及P0等参数中的任意一个或者多个。
进一步的，基站还可基于BPL配置第二类型参数。在本申请实施例中，基于BPL配置的参数可称为第二类型参数，具体可配置每个BPL对应的第二类型参数。第二类型参数也可包括alpha，delta以及P0等参数中的任意一个或者多个。需要说明的是，上述alpha，delta以及P0等参数可配置为第一类型参数也可配置为第二类型参数，但是上述alpha，delta以及P0中任一参数不重复配置。即，上述alpha，delta以及P0可为第一类型参数或者第二类型参数中的一种。第一类型参数和第二类型参数的配置方式可包括如下多种实现方式：
实现方式一：
在一些可行的实施方式中，基站配置基于BPL Group的第一类型参数之外，还可配置上述BPL对应的第二类型参数。在本申请实施例中，同一个BPL集合中的每个BPL可单独配置一套第二类型参数，即，每个BPL对应一套第二类型参数。上述第二类型参数可包括alpha，delta以及P0等参数中的任意一个或者多个，并且任一BPL的上行功率控制时所选的第一类型参数和第二类型参数中不包括相同的参数。例如，第一类型参数和第二类型 参数的配置结果可参见如下表2所示的实现方式中的任一种。表2为第一类型参数和第二类型参数的一配置示意表：
表2
Figure PCTCN2018084378-appb-000002
需要说明的是，上述表2中所示配置方式仅是部分可行的实现方式，具体还可包括上述alpha，P0以及delta的任意组合得到的配置方式，在此不做限制。
实现方式二：
需要说明的是，在一些可行的实施方式中，基站可基于BPL Group配置所有的功率控制参数，即上述功率控制参数(包括alpha，delta以及P0)均可基于BPL集合配置。第一类型参数可包括alpha，delta以及P0。此时，功率控制参数均可基于BPL集合配置，无需每个BPL单独配置，操作简单，信令开销更小。
实现方式三：
在一些可行的实现方式中，上述参数P0也可分成两部分进行配置，例如，P0＝P01+P02。例如，在一些可行的实施方式中，P0的取值范围较大，且属于半静态配置的参数，将P0指示给终端设备所需消耗可比特数较多，参数配置的信令开销大。若将P0划分为P01和P02，其中，P01的取值用于确定P0的大概取值范围，P02的取值范围较小，对P0的取值在P01的基础上进行微调。其中，P01基于BPL group配置，可降低参数配置的信令开销，P02基于BPL group内的BPL配置，可提高功率控制的准确性。第一类型参数包括：alpha、delta、P0的第一部分P01中的一个或者多个。第二类型参数包括：Alpha、P0的第二部分P02以及delta中的一个或者多个，并且第二类型参数与第一类型参数不同。例如，第一类型参数和第二类型参数的配置结果可参见如下表3所示的实现方式中的任一种。表3为第一类型参数和第二类型参数的配置示意表：
表3
Figure PCTCN2018084378-appb-000003
需要说明的是，上述表3中所示配置方式仅是部分可行的实现方式，具体还可包括上述alpha，P01，P02以及delta的任意组合得到的配置方式，在此不做限制。上述P01基于BPL group配置，P02基于BPL group内的BPL配置的实现方式适用于上述实现方式一和实现方式二。
S302，基站向终端设备发送所述功率控制参数。
终端设备接收基站发送的上述功率控制参数。
S303，终端设备根据所述功率控制参数确定BPL的上行功率。
在一些可行的实施方式中，基站可通过信令将上述功率控制参数下发给终端设备。可选的，基站可通过一条信令下发第一类型参数和第二类型参数，也可通过多条信令将第一类型参数和第二类型参数分开下发给终端设备，在此不做限制。终端设备通过信令接收到基站通知的第一类型参数和第二类型参数之后，则可根据接收到的功率控制参数确定各个BPL的上行功率。
可选的，基站还可通过信令向终端设备下发指示信息(即第一信息)，通过上述第一信息将功率控制参数的类型通知给终端设备，其中，上述功率控制参数的类型包括第一类型参数和第二类型参数。例如，基站可其中，上述信令可包括：RRC、系统信息、DCI以及MAC CE中的任意一种。具体实现中，例如，基站可通过信令将功率控制参数P0对应的group ID或者group index等类型指示信息发送给终端设备，以通知终端设备功率控制参数P0为第一类型参数。或者基站可通过将功率控制参数delta对应的BPL ID等类型指示信息发送给终端设备，以通知终端设备功率控制参数delta为第二类型参数等。
可行的，基站可将功率控制参数及其类型通过一条信令下发给终端设备，也可将功率控制参数和功率控制参数的类型通过多条信令分开下发给终端设备，在此不做限制。
在一些可行的实施方式中，基站还可通过高层信令(例如系统信息、RRC信令或者MAC CE等)指示终端设备下行链路路损估计值PL的计算模式，包括第一计算模式和第二计算模式。第一计算模式为基于BPL集合计算PL，即计算每个BPL集合对应的PL。其中，一个BPL集合的所有BPL使用同一个PL，即一个BPL group维护一个PL。上述第二计算模式为基于BPL计算PL，即，计算每个BPL对应的PL，其中，每个BPL使用一个PL，即BPL group内的每个BPL维护一个PL。终端设备通过高层信令接收到基站的指示之后，则可根据上述第一计算模式或者第二计算模式计算每个BPL集合对应的PL，或者每个BPL对应的PL，进而可结合上述第一类型参数和第二类型参数计算每个BPL的上行功率。如下表4，是在上述表2所示的参数配置方式中，结合PL的计算模式得到的另一参数配置表：

如下表5，是在上述表3所示的参数配置方式中，结合PL的计算模式得到的另一参数配置表：
表5
Figure PCTCN2018084378-appb-000005
具体实现中，终端设备根据信令确定基站所指示的上述表4或表5包含的信息之后，则可根据上述任一配置方式中PL的计算模块计算该配置方式对应的PL，进而可结合该配置方式包括的第一类型参数和第二类型参数确定该配置方式对应的BPL的上行功率。
在本申请实施例中，基站可通过基于BPL集合配置的第一类型参数和基于BPL配置的第二类型参数，实现对终端设备的上行功率的控制，可降低配置上行功率的功率控制参数的信令开销，节省上行控制的资源消耗，适用性更高。
此外，针对探测参考信号(sounding reference signal,SRS)功率的控制，本申请实施例还提供了一种上行功率控制的实现方式。参见图5是本申请实施例提供的上行功率控制的实施例流程示意图，本申请实施例提供的上行功率控制的方法包括步骤：
S501，基站配置终端设备的SRS发送功率的模式。
在一些可行的实现方式中，SRS用于波束扫描(beam sweeping)的场景。基站可配置终端设备的SRS发送功率的模式。
其中，上述SRS发送功率的模式可包括使用相同的发送功率，即每个发送SRS的波束使用相同的发送功率。
进一步的，在一些可行的实现方式中，基站还可将终端设备的多个不同的SRS配置为多个SRS资源组，即基站可配置至少两个SRS资源组。其中，上述至少两个SRS资源组中每个SRS资源组包括至少一个发送SRS的波束。上述SRS资源组中的SRS发送功率的模式可包括SRS资源组之间使用不同的发送功率，每个SRS组中的SRS之间使用相同的发送功率。
S502，基站根据所述SRS发送功率的模式，配置所述终端设备的SRS发送功率。
在一些可行的实现方式中，基站配置各个SRS资源组中的SRS发送功率的模式为使用相同的发送功率，则终端设备可确定各个SRS发送功率中的最小SRS发送功率，并确定各个SRS的发送功率为上述最小SRS发送功率。即，每个SRS发送功率均配置为上述最小SRS发送功率。可行的，基站也可预定义一个SRS发送功率，并将每个SRS发送功率均配置为上述预定义的SRS发送功率。其中，上述预定义的SRS发送功率可为第一个SRS资源对应的发送功率等，在此不做限制。此外，基站也可配置一个SRS资源的指示信息，上述SRS资源的指示信息用于指示终端设备根据上述SRS资源的发送功率确定各个SRS的发送功率。即每个SRS发送功率均与上述SRS资源的发送功率相同或者相关等，在此不做限制。
进一步的，在一些可行的实现方式中，基站可配置各个SRS资源组中的SRS发送功率的模式为使用相同的发送功率并且SRS资源组间使用不同的发送功率。基站配置各个SRS发送功率时，可首先配置各个SRS资源组对应的SRS发送功率，进而可配置每个SRS资源中的各个BPL的SRS发送功率。其中，上述至少两个SRS资源组中至少一个SRS资源组的SRS的发送功率与其他SRS资源组的SRS的发送功率不同。基站可根据上述SRS发送功率的配置方式配置一个SRS资源组对应的SRS发送功率，其中，同一个SRS资源组具有相同的SRS发送功率。进一步的，基站配置其他SRS资源组与该SRS资源组间的功率差。其中，其他SRS资源组对应的SRS可相同，也可不同。每个SRS资源组的SRS发送功率均可根据上述实现方式确定，在此不再赘述。
S503，基站通过信令通知终端设备SRS的发送功率。
S504，终端设备根据所述基站的通知确定SRS的发送功率。
本申请实施例可降低SRS发送功率配置的信令开销，适用性更高。
