具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
应理解，本申请实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进LTE***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、新无线(New Radio，NR)或未来的5G***等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信***，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)***、低密度签名(Low Density Signature，LDS)***等，当然SCMA***和LDS***在通信领域也可以被称 为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输***，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)***等。
示例性的，本申请实施例应用的通信***100如图1所示。该通信***100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM***或CDMA***中的基站(Base Transceiver Station，BTS)，也可以是WCDMA***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络设备gNB或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信***100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于用户设备(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。接入终端可以是蜂窝电话、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，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本发明实施例并不限定。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)或车联网(vehicle to everything，V2X)通信。这种终端设备与终端设备之间的直接通信模式可以称为侧行(Sidelink，SL)通信。这种通信的特点是网络设备不再是控制中心，且终端设备可以在没有网络的情况下直接通信。以车联网为例，车辆间可以跟附近的车辆通信，进行防撞预警等应用。
可选地，5G***或5G网络还可以称为新无线(New Radio，NR)***或NR网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信***100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信***100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/***中具有通信功能的设备可称为通信设备。以图1 示出的通信***100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信***100中的其他设备，例如移动性管理实体(Mobility Management Entity，MME)，服务网关(Serving Gateway，S-GW)或分组数据网关(PDN Gateway，P-GW)等，本申请实施例中对此不做限定。
应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在SL通信***中，终端设备与终端设备之间的通信可以不依赖于传统的蜂窝通信网络，那么蜂窝通信网络与终端设备的关系可以包括：终端设备在蜂窝网络覆盖区域内或终端设备不在蜂窝网络覆盖范围内。
目前，当终端设备在蜂窝网络覆盖区域内时，可以采用开环功率控制，即由网络设备控制终端设备对终端设备之间的发送功率。具体地，可以通过以下公式计算获得：
P PSSCH＝min{P CMAX,PSSCH,10log 10(M PSSCH)+P o_PSSCH+α PSSCH.PL}
其中，P CMAX,PSSCH为终端设备的最大发送功率，M PSSCH为终端设备所占用的资源块(Resource Block，RB)数目，P o_PSSCH为网络设备配置的开环功率参数，α PSSCH为网络设备配置的路径损耗加权系数，PL是路径损耗。
当终端设备不在蜂窝网络覆盖区域内时，终端设备的发送功率不受网络设备的控制，终端设备始终采用最大发送功率进行发射。
无论是采用上述哪种方式的发送功率发射，都可能会导致终端设备持续采用不合适的发送功率，从而影响了通信性能。
因此，本申请实施例提供了一种功率调整的方法200，该方法可以通过终端设备之间的功率协商机制来不断调整发送功率，具体地，如图2所示，该方法200包括以下部分或全部内容：
S210，第二终端设备向第一终端设备发送第一信号；相应地，第一终端设备接收第二终端设备发送的第一信号；
S220，第一终端设备基于第一信号，向第二终端设备发送功率控制命令；相应地，第二终端设备接收第一终端设备基于第一信号发送的功率控制命令，该功率控制命令用于调整该第二终端设备的发送功率。
具体地，在SL通信中，第一终端设备可以作为接收端，第二终端设备可以作为发送端。发送端可以向接收端发送信号，而接收端则在接收到发送端发送的信号之后，基于该信号，生成并向发送端发送功率控制命令，例如，增加发送功率的命令(即本文中提到的增加功率控制命令)、降低发送功率的命令(即本文中提到的降低功率控制命令)或发送功率保持不变的命令。进而，在发送端接收到该功率控制命令之后，可以对发送功率做相应的调整，以用于下一次信号的发送。接收端可以在每一次接收到信号之后， 都可以向发送端反馈功率控制命令；相应的，发送端在每一次接收到接收端反馈的功率控制命令，都可以对发送功率进行调整。从而达到实时精准地控制发送功率，以提高通信性能。
可选地，接收端向发送端反馈的功率控制命令，除了包括增加、降低、不变的简单指示之外，还可以增加相应的变化值。例如，该功率控制命令指示增加发送功率，还可以指示增加一个步长的功率，其中，该一个步长的功率可以由网络设备提前配置好。或者，该功率控制命令还可以直接指示一个偏移量。本申请实施例对功率控制命令包括的具体内容不作限定。
当发送端不位于蜂窝网络覆盖区域中，发送端的发送功率不受网络设备的控制，而是直接根据接收端反馈的功率控制命令调整发送功率。
当发送端位于蜂窝网络覆盖区域中，一种可能的实现方式是，网络设备会为发送端配置相应的功率控制参数，例如上述公式中的开环功率参数或路径损耗加权系数等。但发送端会忽略网络设备配置的功率控制参数，而是根据接收端反馈的功率控制命令调整发送功率。另一种可能的实现方式是，发送端可以提前与网络设备进行交互，通知网络设备不需要向其配置相应的功率控制参数，进而发送端可以根据接收端反馈的功率控制命令调整发送功率。
可选地，在本申请实施例中，所述第一终端设备根据所述第一信号，向所述第二终端设备发送功率控制命令，包括：所述第一终端设备根据发送所述第一信号的第一链路质量信息、所述第一信号所属业务与第二信号所属业务的业务优先级信息和所述第一信号与第三信号的干扰情况中的至少一种，向所述第二终端设备发送所述功率控制命令，所述第二信号和所述第三信号均为所述第一终端设备接收的除所述第二终端设备之外的终端设备的信号。
具体地，接收端可以参考一些信息来生成功率控制命令。例如，接收端可以获取发送端发送的第一信号的链路质量信息，并判断该链路质量信息指示的链路质量的好坏。若链路质量不好到满足一定条件，那么接收端生成的功率控制命令可以是增加功率控制命令；而若链路质量好到满足一定条件，那么接收端生成的功率控制命令可以是降低功率控制命令。该链路质量信息可以通过误码率、信噪比或信号强度等一些参数来表征。以误码率为例，当接收端接收到第一信号之后，对其进行解调并得到误码率信息，如果误码率高于一定门限，则接收端认为发送端应该增加发送功率，即向发送端反馈增加功率控制命令；相反地，如果误码率低于一定门限，则接收端认为发送端应该降低发送功率，即向发送端反馈降低功率控制命令。其中，可以针对误码率设置一个门限，也可以设置两个门限，高的门限用来作为生成增加功率控制命令的判断依据，而低的门限用来作为生成降低功率控制命令的判断依据。
可选地，当接收端判断出来链路质量好到满足一定条件时，接收端也可以先参考当前接收端相对于发送端的移动信息，再确定要不要生成降低功率控制命令，例如，相对移动速度。如果该相对移动信息变化较大，则可以认为不适合降低发送端的发送功率， 也就是说，可以不向发送端反馈功率控制命令。如果该相对移动信息变化不大，则认为适合降低发送端的发送功率，也就是说，可以向发送端反馈降低功率控制命令。通过考虑接收端与发送端的相对移动信息，避免二者相对移动变化过快且功率降低过大导致的链路失败问题。可选地，接收端可以通过观测发送端的发送功率(即接收端的接收功率)的变化情况来确定相对移动信息。例如，接收端可以每接收到一次发送端的信号，就记录该信号的接收功率。具体地，可以测量信号强度，如获取参考信号接收功率(Reference Signal Receiving Power，RSRP)、接收的信号强度指示(Received Signal Strength Indication，RSSI)等参数。
类似地，确定接收端与发送端的相对移动的变化情况，也可以设置一些条件。例如，可以为相对移动速度设置一个门限，当获取的相对移动信息指示的相对移动速度大于或等于该门限，则可以认为接收端与发送端之间相对移动变化过大；而当获取的相对移动信息指示的相对移动速度小于该门限，则可以认为接收端与发送端之间相对移动变化不大。
需要说明的是，任何可以表征接收端与发送端的相对移动的变化情况的信息都可以是本申请实施例中的相对移动信息，并不限定于是上述所举例说明的相对移动速度。
可选地，判断链路质量好坏的条件可以是由服务质量(Quality of Service，QoS)要求确定的。也就是说，上述第一信号的第一链路质量信息所指示的链路质量的好坏是由第一信号所属业务对应的QoS要求判断的。可替代地，判断链路质量好坏的条件还可以是网络设备重新配置或者协议重新约定的一个条件。
可选地，在发送端接收到接收端反馈的功率控制命令之后，若发送端对发送功率进行了调整，那么发送端还可以向接收端发送功率余量信息，也就是上报调整后的发送功率与最大发送功率之间的差值。如，调整后的发送功率为最大发送功率，那么上报的功率余量信息则为0。
下面将结合图3描述本申请一个实施例的详细流程。本领域技术人员理解，该流程仅用于示意，并不用于限定。
如图3所示，该流程可以包括：
S301，终端设备A初始以发送功率1向终端设备B发射信号；
S302，终端设备B对终端设备A发射的信号进行接收解调得到误码率；
S303，终端设备B判断误码率是否高于预设门限；
S304，若高于，则终端设备B向终端设备A发送增加功率控制命令，例如，可以将发送功率1调整到发送功率2，发送功率2高于发送功率1；
S305，若低于，则终端设备B可以继续观测与终端设备A的相对移动信息；
S306，判断终端设备B与终端设备A的相对移动性是否较高；
S307，若终端设备B与终端设备A的相对移动性较高，则终端设备B不向终端设备A反馈功率控制命令；
S308，若终端设备B与终端设备A的相对移动性不高，则终端设备B向终端设备A 发送降低功率控制命令，例如，可以将发送功率1调整到发送功率3，发送功率3低于发送功率1；
S309，终端设备A可以基于接收到的功率控制命令，调整发送功率，并向终端设备B上报功率余量信息。
终端设备B和终端设备A可以在后续时间内重复步骤S301～S308。
可选地，在本申请实施例中，接收端在生成功率控制命令时，也可以只考虑接收端与发送端的相对移动信息，例如，相对距离越来越远，那么接收端生成增加功率控制命令；而相对距离越来越近，则接收端生成降低功率控制命令。
上述各种实施例可以适用于单点通信模式，即两个终端设备之间的交互，在生成功率控制命令时可以不考虑其他终端设备的干扰。上述各种实施例也可以适用于多终端设备分布的通信模式，也就是说一个终端设备与多个终端设备之间的交互。那么作为接收端来说，除了考虑上述链路质量信息之外，还可以结合其他终端设备与发送端之间的相互影响。例如，其他终端设备向接收端发送的信号对发送端向接收端发送的信号的干扰或者其他终端设备向接收端发送的信号与发送端向接收端发送的信号的业务优先级等。或者，接收端可以单独考虑其他终端设备与发送端之间的相互影响，以生成功率控制命令。
示例一，接收端为第一终端设备，发送端为第二终端设备，其他终端设备为第三终端设备，其中，第二终端设备向第一终端设备发送的信号为第一信号，第三终端设备向第一终端设备发送的信号为第三信号。
若第一信号对第三信号有干扰，那么第一终端设备可以认为第二终端设备的发送功率过高，即向第二终端设备发送降低功率控制命令，进一步地，第一终端设备还可以认为第三终端设备的发送功率过低，即向第三终端设备发送增加功率控制命令；而若第三信号对第一信号有干扰，那么第一终端设备可以认为第二终端设备的发送功率过低，即向第二终端设备发送增加功率控制命令，进一步地，第一终端设备还可以认为第三终端设备的发送功率过高，即向第三终端设备发送降低功率控制命令。
示例二，接收端为第一终端设备，发送端为第二终端设备，其他终端设备为第四终端设备，其中，第二终端设备向第一终端设备发送的信号为第一信号，第四终端设备向第一终端设备发送的信号为第二信号。
若第一信号所属业务比第二信号所属业务的优先级高，那么第一终端设备可以认为需要增加第二终端设备的发送功率，以保证第一终端设备发送的信号有高的接收质量、低的误码率等，甚至不允许出错，即向第二终端设备发送增加功率控制命令，进一步地，第一终端设备还可以认为第三终端设备发送的信号可以允许低的接收质量或延时等，即向第三终端设备发送降低功率控制命令；而若第一信号所属业务比第二信号所属业务的优先级低，那么第一终端设备可以认为需要降低第二终端设备的发送功率，即向第二终端设备发送降低功率控制命令，进一步地，第一终端设备还可以认为需要增加第三终端设备的发送功率，即向第三终端设备发送增加功率控制命令。
可选地，第一终端设备在生成功率控制命令时，也可以综合考虑各个终端设备发送信号的链路质量信息、不同终端设备发送信号的干扰情况以及不同终端设备发送信号的业务优先级。
例如，可以将链路质量信息与干扰情况结合，假设第二终端设备发送的第一信号对第三终端设备发送的第三信号造成干扰，第一终端设备可以先判断一下第一信号的链路质量是否较好，若此时较好，那么第一终端设备可以向第二终端设备发送降低功率控制命令，反之，则第一终端设备不向第二终端设备发送降低功率控制命令，而是通过第一终端设备向第三终端设备发送增加功率控制命令来降低第二终端设备发送的信号对第三终端设备发送的信号的干扰。
再例如，可以将干扰情况与业务优先级信息结合，假设第二终端设备发送的第一信号对第三终端设备发送的第三信号造成干扰，第一终端设备可以先判断一下第一信号所属业务与第三信号所属业务的业务优先级，若第一信号的业务优先级高于第三信号，那么第一终端设备不向第二终端设备发送降低功率控制命令，而是通过向第三终端设备发送增加功率控制命令来降低第二终端设备发送的信号对第三终端设备发送的信号的干扰；反之，则第一终端设备直接向第二终端设备发送降低功率控制命令。
需要说明的是，上述列举的用于生成功率控制命令的可参考信息可以组合成各种不同实施例，为了简洁，此处不再穷举，但本领域技术人员应理解，本申请实施例不限于此。
图4示出了一种多终端设备分布的应用场景图。在图4中，终端设备A可以作为接收端，而终端设备B、终端设备C和终端设备D均可以作为发送端。其中，终端设备A可以充当这个通信组的中心节点。也就是说，终端设备A可以同时接收来自终端设备B、终端设备C以及终端设备D的信号，由于终端设备B、终端设备C以及终端设备D与终端设备A的相对距离不同，它们的信号到达终端设备A时的信号强度就会出现差异，因此，对于终端设备A来说，终端设备B、终端设备C以及终端设备D的信号质量不同，在某些情况下，离得远的终端设备B的信号可能会被离得近的终端设备C和/或终端设备D的信号干扰，从而导致无法正确接收。那么可以通过以下实施例来进行改善：
首先，终端设备A接收来自其他终端设备的信号。可选地，这些信号中携带有业务优先级信息，例如，可以是QoS信号质量要求信息等。
其次，终端设备A判断各个信号质量是否满足要求，详见上述链路质量的判断方式。
再次，终端设备A发现某些业务优先级高的信号质量不满足要求(例如，终端设备B的信号的业务优先级高于终端设备C和/或终端设备D的信号，进一步地，终端设备B的信号可以属于防撞业务)，那么终端设备A可以进一步地结合终端间的移动性情况来对各个终端设备的发送功率进行调整：
若终端设备A与终端设备C和/或终端设备D的相对移动性不高，终端设备A可以通知终端设备C和/或终端设备D降低其发送功率以减少干扰；
终端设备A还可以通知终端设备B来增加其发送功率。
终端设备A可以在后续时间内重复上述各个步骤持续监测并协调多个终端设备间的业务需求。
图5示出了另外一种分布式终端设备的示意图。其中各个终端处于互相通信的模式，也就是说，终端设备A分别与终端设备B和终端设备C互相通信。
在实际SL通信运行中，以车联网为例，在终端设备A周围会有很多其它终端设备，但终端设备A不需要跟所有的终端进行通信。以简单的防撞为例，终端设备A可能只需要跟前面或后面的少数几个终端设备进行通信即可，也即其发送功率只需要保证与其相关的少数终端设备能够正常接收解调就可以。这样，当所有终端设备都按照这种逻辑来进行功率的协商时，从任何一个终端设备看其发送功率都出于一个比较低且够用的水平，而最终的结果是整个SL通信***的功率处于一个比较低的水平，相互干扰也比较低，达到了整体功率效率的最优化。
对于相互通信的两个终端设备来说，可以采用本申请实施例的方式来进行功率控制，也就是说，发送端向接收端发送信号，而接收端基于上述各种实施例向发送端反馈功率控制命令。在分布式终端设备的场景下，一个终端设备可能会向多个终端设备发送信号，而该终端设备就可能收到多个终端设备反馈的功率控制命令。那么该终端设备可以通过以下两种方式进行发送功率的调整：
如果该终端设备向多个终端设备发送信号属于一对多的方式，也即多播方式，若多个终端设备反馈的功率控制命令一致，例如，都反馈的是增加功率控制命令，那么该终端设备就增加发送功率；若多个终端设备反馈的功率控制命令不一致，例如，一些反馈的是增加功率控制命令，而另外一些反馈的是降低功率控制命令，那么该终端设备就需要结合接收到的多个功率控制命令来综合考虑到底是增加发送功率还是降低发送功率。可选地，多个终端设备除了向该终端设备反馈功率控制命令之外，还可以向该终端设备反馈信号强度，那么该终端设备可以结合各个终端设备反馈的信号强度来确定增加发送功率还是降低发送功率。具体地，该信号强度可以表征各个终端设备与该终端设备之间的距离、相对移动性等。例如，对于反馈的是降低发送功率控制命令的终端设备来说，若这些终端设备的相对移动性较高，那么终端设备可以忽略降低功率控制命令，而直接根据增加功率控制命令来增加发送功率。
如果该终端设备向多个终端设备发送信号属于一对一的方式，那么该终端设备可以分别针对各个终端设备反馈的功率控制命令调整发送功率。
下面我们以图5中的终端A为例阐述本申请一个实施例。
1、在初始阶段，终端A向周边的其它终端(此处假设周边的终端为B和C)发射初始信号，可选地，发射的信号中携带了其初始发射功率强度P 0。
2、终端B和C接收到A的初始信号后向终端A反馈接收端的信号强度P 1和P 2，以及各自的功率控制命令。
其中，功率控制命令包括增加或减少发送功率。
终端B和C可以通过考虑接收链路质量信息、相对移动性等因素，给出功率控制命 令。如在误码率低、移动性低的情况下，可以给出降低较大功率的命令。反之则增加、不降低或降低一个较小功率的命令。
3、终端A收到来自终端B和终端C的P 1和P 2以及各自的功率控制命令后，根据P 1和P 2可大致知道当前的终端间距信息及相对移动性信息。终端A调整对终端B及终端C的发送功率：
此处A跟B、A跟C可以为相互独立的调整过程，也可以为A结合B及C的功率控制命令后进行统一处理这取决于A跟B及A跟C之间进行的业务类型，如A此时为一对多的广播式业务则A将只会采取一种增加、减少或维持当前功率的动作，而如果A此时为与B跟C的一对一业务，则A可以单独进行相应功率的调整等。可选地，若为一对一业务，A向B或C发送的信号中分别携带B或C的标识信息，以确保B和C分别接收到属于自己的信号。
终端B和终端C监测其与终端A的功率变化情况，并如步骤2和3所述对终端A的功率进行动态调整。
因此，通过以上方式，终端A的发送功率可维持在一个相对较低但够用的水平。与之类似的处理方式，其它终端也可以达到相同的效果。最终整个SL通信***的功率水平可以保持一个较低的水平，避免互相干扰。通过相关通信终端反馈的功率控制命令及辅助功率信息等可以确保发射端终端的功率合适，最终维持分布式***的功率平衡。
应理解，发送端描述的第二终端设备与接收端的第一终端设备之间的交互及相关特性、功能等与第一终端设备的相关特性、功能相应。并且相关内容在上述方法200中已经作了详尽描述，为了简洁，在此不再赘述。
还应理解，在本申请的各种实施例中，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，而不应对本申请实施例的实施过程构成任何限定。
