Description

一种功率控制方法及装置
本申请要求于2023年7月6日提交中国国家知识产权局、申请号为202310826242.5、申请名称为“一种功率控制方法及装置”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，尤其涉及一种功率控制方法及装置。
背景技术
下一代无线通信(next radio，NR)中引入子带全双工(non-overlap subband full duplex，SBFD)，以满足上行业务的需求。具体的，SBFD支持在频域上划分不同的子带。基站在不同的子带上可以同时进行上下行通信，以实现基站侧的全双工。但是，对于终端设备而言，仍然为半双工。也就是说，终端设备在一个时间点只能在相应的子带上进行上行发送或者下行接收。其中，在时域上，支持基站在不同的子带进行上下行通信的符号可以称之为SBFD符号，也即插入了上行子带的符号，而在SBFD符号上终端设备的传输方向为上行或下行。
由于终端设备在SBFD符号上可能进行上行发送，因此SBFD的引入会对双连接(dual connectivity，DC)通信产生影响。
发明内容
本申请公开了一种功率控制方法及装置，在包含针对第二连接的传输配置为SBFD、灵活和/或上行的子时间单元的第一时间单元上实现对第一连接的发送功率的控制，有助于降低第一连接和第二连接同时进行上行发送时之间的相互干扰，提高通信性能。
第一方面，本申请提供了一种通信方法，应用于支持通过第一连接和第二连接通信的终端设备中，所述方法包括：通过第一连接，在第一时间单元发送第一信息，第一信息的发送功率小于或等于第一功率，第一时间单元包括至少一个子时间单元，其中，所述至少一个子时间单元针对第二连接的传输配置为上行、灵活和/或SBFD。
在该技术方案中，终端设备通过第一连接在第一时间单元进行上行发送时，在第一时间单元中包括针对第二连接的传输配置为上行、灵活、和/或SBFD的子时间单元，这种情况下，将针对第一连接的发送功率限制为小于或等于第一功率，有助于降低第一连接和第二连接同时进行上行发送时之间的相互干扰，提高通信性能。
在一种可能的实现方式中，第一功率为针对第一连接配置的最大发送功率。
在一种可能的实现方式中，所述至少一个子时间单元中针对第二连接的传输配置为SBFD的子时间单元不用于下行接收。
在一种可能的实现方式中，所述方法还包括：接收第一指示信息，第一指示信息指示第一时间单元中针对第二连接的传输配置为SBFD的子时间单元的传输方向。
在一种可能的实现方式中，所述方法还包括：接收第二指示信息，第二指示信息指示第一时间单元中子时间单元针对第二连接的传输配置。
在一种可能的实现方式中，若第一时间单元针对第二连接的传输配置为下行，则第一信息的发送功率小于或等于第二功率，第二功率为终端设备的最大总发送功率，第二功率大于第一功率。
在该技术方案中，在第一时间单元上终端设备不会在第二连接上进行上行发送，因此当终端设备通过第一连接在第一时间单元上进行上行发送时的发送功率并非限制为小于或等于第一功率，而是限制为小于或等于第二功率，有助于提高终端设备的发送功率的利用率。
在一种可能的实现方式中，第一连接为终端设备与第一网络设备之间的连接，第二连接为终端设备与第二网络设备之间的连接。
第二方面，本申请提供了一种装置，所述装置包括用于实现第一方面所述的方法的单元。
第三方面，本申请提供另一种装置，包括处理器；该处理器，用于执行第一方面所述的方法。
在一种可选的实施方式中，该装置还可以包括存储器；该存储器用于存储计算机程序；处理器，具体用于从该存储器中调用计算机程序，执行第一方面所述的方法。
第四方面，本申请提供一种芯片，该芯片用于执行第一方面所述的方法。
第五方面，本申请提供一种芯片模组，该芯片模组包括通信接口和芯片，其中：通信接口用于进行芯片模组内部通信，或者用于该芯片模组与外部设备进行通信；该芯片用于执行第一方面所述的方法。
第六方面，本申请提供一种计算机可读存储介质，所述计算机可读存储介质存储有计算机程序，所述计算机程序包括程序指令，所述程序指令被计算机运行时，执行第一方面所述的方法。
第七方面，本申请提供一种包括计算机程序或指令的计算机程序产品，当计算机程序或指令在计算机上运行时，使得计算机执行如第一方面所述的方法。

又例如，子时间单元配置了上行子带，该子时间单元又可以称之为SBFD子时间单元。终端设备在该子时间单元上可以进行上行发送或者下行接收。具体的，终端设备在SBFD子时间单元是进行上行发送还是下行接收可以基于网络设备指示来确定。
在一种可能的实现方式中，时间单元的传输配置可以包括SBFD和/或非SBFD(Non-SBFD)，即时间单元可以包括SBFD时间单元和/或Non-SBFD时间单元，其中，SBFD时间单元指配置了上行子带的时间单元，Non-SBFD时间单元包括上行时间单元、下行时间单元和/或灵活时间单元。也就是说，时间单元的传输配置可以包括上行、下行、灵活和/或SBFD。同理，子时间单元的传输配置可以包括SBFD和/或非SBFD(Non-SBFD)，即子时间单元可以包括SBFD子时间单元和/或Non-SBFD子时间单元，其中，SBFD子时间单元指配置了上行子带的子时间单元，Non-SBFD子时间单元包括上行子时间单元、下行子时间单元和/或灵活子时间单元。也就是说，子时间单元的传输配置可以包括上行、下行、灵活和/或SBFD。
在一些实施例中，子时间单元配置了上行子带还可以描述为：子时间单元对应的子带插入了上行子带，具体的，可以在下行子时间单元和/或灵活子时间单元对应的子带插入上行子带。换言之，网络设备可以将配置给终端设备的下行子时间单元和/或灵活子时间单元的传输配置更新为SBFD。也就是说，网络设备可以将配置给终端设备的下行子时间单元和/或灵活子时间单元进一步配置为SBFD子时间单元。
需要说明的是，对于网络设备侧来说，在SBFD子时间单元可以同时进行上下行通信。即，对于网络设备侧来说，与SBFD子时间单元对应的子带可以包括上行子带和下行子带。
但是，对于终端设备来说，SBFD子时间单元用于上行发送、还是下行接收，还是灵活通信，是由网络设备指示给终端设备。例如，对于终端设备来说，SBFD子时间单元用于上行发送，则该SBFD子时间单元对应的子带为上行子带。即，终端设备在SBFD子时间单元、以及与该SBFD子时间单元对应得上行子带上进行上行发送。
以符号为例。符号的传输配置为上行，该符号可以称之为上行符号。符号的传输配置为下行，该符号可以称之为下行符号。符号的传输配置为灵活，该符号可以称之为灵活符号。符号的传输配置为SBFD，该符号可以称之为SBFD符号。或者，符号配置了上行子带，该符号可以称之为SBFD符号。
以时隙为例。时隙的传输配置为上行，该时隙可以称之为上行时隙。时隙的传输配置为下行，该时隙可以称之为下行时隙。时隙的传输配置为灵活，该时隙可以称之为灵活时隙。时隙的传输配置为SBFD，该时隙可以称之为SBFD时隙。或者，时隙配置了上行子带，该时隙可以称之为SBFD时隙。
需要说明的是，对于一个时间单元来说，一个时间单元包括的所有子时间单元的传输配置可以是相同的。例如，一个时间单元包括的所有子时间单元的传输配置均为上行，该时间单元又可以称之为上行时间单元。或者，一个时间单元包括的部分子时间单元的传输配置是相同的，部分子时间单元的传输配置是不同的。例如，一个时间单元包括14个子时间单元，其中4个子时间单元的传输配置均为下行，7个子时间单元的传输配置均为上行，1个子时间单元的传输配置为灵活，2个子时间单元的传输配置均为SBFD。
以时隙为例。时隙的传输配置又可以称之为时隙配置、slot configuration。以子帧为例。子帧的传输配置又可以称之为子帧配置。以符号为例。符号的传输配置又可以称之为符号配置。
本申请实施例提供了一种功率控制方法，使得终端设备通过第一连接和第二连接通信的情况下，可以在包含针对第二连接的传输配置为SBFD、灵活和/或上行的子时间单元的时间单元上实现对第一连接的发送功率的控制。从而有助于降低引入SBFD后对双连接通信的影响，提升通信性能。
本申请实施例可以应用于终端设备存在两个或两个以上连接的通信场景。例如，本申请实施例可以应用于DC场景。其中，DC可以为NR-DC(new radio-dual connectivity)、EN-DC(e-UTRAN nR-dual connectivity)、NGEN-DC(next generation ran E-UTRA new radio-dual connectivity)、NE-DC(new radio E-UTRA-dual connectivity)。
如图1所示，为本申请实施例的一种DC场景下通信系统架构的示意图。如图1所示，终端设备与第一网络设备、第二网络设备连接。其中，终端设备与第一网络设备之间的连接为第一连接，终端设备与第二网络设备之间的连接为第二连接，终端设备可以同时在第一连接和第二连接上进行通信。在图1所示的DC场景下，第一网络设备和第二网络设备中的一个网络设备作为主RAN节点，另一个网络设备作为辅RAN节点。主RAN节点是在DC场景中直接连接到核心网并管理控制信令的节点，辅RAN节点连接到主节点。
需要说明的是，图1仅为DC场景下的通信系统架构的一个示意图，并不构成对DC场景下通信系统架构的限定。例如，图1所示的通信系统架构中可包括两个或以上的网络设备，两个或两个以上的终端设备等。
再例如，本申请实施例也可以应用于一个终端设备与一个网络设备之间存在两个或两个以上连接的场景。
下面对本申请实施例的功率控制方法进行详细介绍。该功率控制方法可以由终端设备执行，也可以由与终端设备匹配的装置(如，芯片、芯片模组或处理器等置于终端设备内部的装置)执行。
以下以终端设备通过第一连接和第二连接通信为例，对功率控制方法进行说明。示例的，第一连接为终端设备与第一网络设备之间的连接，第二连接为终端设备与第二网络设备之间的连接。例如，第一网络设备为主RAN节点，第二网络设备为辅RAN节点。再例如，第一网络设备为辅RAN节点，第二网络设备为主RAN节点。或者，第一连接和第二连接为终端设备与一个网络设备之间的两个连接。
如图2所示，为本申请实施例的一种功率控制方法的流程示意图，具体包括以下步骤。
步骤201、终端设备确定第一信息。
其中，第一信息为待发送的信息，可以是由终端设备生成的，也可以是终端设备从其它设备获取的。本申请实施例对第一信息的获取方式不做限定。例如，第一信息为待发送的上行信息。
需要说明的是，步骤201为可选步骤。也就是说，终端设备可以不执行步骤201。
步骤202、终端设备通过第一连接，在第一时间单元发送第一信息，第一信息的发送功率小于或等于第一功率。
其中，第一时间单元包括至少一个子时间单元。该至少一个子时间单元针对第二连接的传输配置为上行、灵活和/或SBFD。也就是说，该至少一个子时间单元包括上行子时间单元、灵活子时间单元、和/或SBFD子时间单元。
本申请实施例中，由于终端设备通过第一连接在第一时间单元进行上行发送时，在第一时间单元中包括针对第二连接的配置为上行子时间单元、灵活子时间单元、和/或SBFD子时间单元的情况下，针对第一连接的发送功率限制为小于或等于第一功率，有助于降低第一连接和第二连接同时进行上行发送时之间的相互干扰，提高通信性能。
示例的，第一功率为针对第一连接配置的最大发送功率。其中，第一功率可以通过协议预定义，也可以为网络设备指示给终端设备的等，本申请实施例对第一功率的获取方式不做限定。例如，在第一连接为终端设备与第一网络设备之间的连接的情况下，向终端设备指示第一功率的网络设备指的是第一网络设备。如，第一网络设备可以通过高层信令或下行链路控制信息(Downlink Control Information，DCI)向终端设备指示第一功率。高层信令可以包括无线资源控制(Radio Resource Control，RRC)信令。
以第一连接为终端设备与第一网络设备之间的连接，第二连接为终端设备与第二网络设备之间的连接，并且第一网络设备为主RAN节点，第二网络设备为辅RAN节点为例，第一功率可以为PMCG，PMCG是针对主小区组(Master Cell Group，MCG)配置的最大发送功率。以第一连接为终端设备与第一网络设备之间的连接，第二连接为终端设备与第二网络设备之间的连接，并且第一网络设备为辅RAN节点，第二网络设备为主RAN节点为例，第一功率可以为PSCG，PSCG是针对辅服务小区(Secondary Cell，SCell)配置的最大发送功率。
例如，以第一时间单元为时隙1为例。如图3A所示，时隙1包括符号0-符号13。其中，符号0-符号13中针对第二连接传输配置为上行的符号为符号7-9，符号0-符号13中针对第二连接传输配置为SBFD的符号为符号10-13，符号0-符号13中针对第二连接传输配置为灵活的符号为符号6，符号0-符号13中针对第二连接传输配置为下行的符号为符号0-5。也就是说，针对第二连接来说，符号0-5为下行符号，符号6为灵活符号、符号7-9为上行符号，符号10-13为SBFD符号。由于在符号6-13上终端设备可能会在第二连接上进行上行发送，因此当终端设备通过第一连接在时隙1上进行上行发送时采用的发送功率小于或等于第一功率。
再例如，以第一时间单元为时隙2为例。如图3B所示，时隙2包括符号0-符号13。其中，符号0-符号13中针对第二连接传输配置为SBFD的符号为符号0-6，符号0-符号13中针对第二连接传输配置为灵活的符号为符号7，符号0-符号13中针对第二连接传输配置为下行的符号为符号8-13。也就是说，针对第二连接来说，符号0-6为SBFD符号，符号7为灵活符号、符号8-13为下行符号。由于在符号0-7上终端设备可能会在第二连接上进行上行发送，因此当终端设备通过第一连接在时隙2上进行上行发送时采用的发送功率小于或等于第一功率。
进一步的，在一些实施例中，该至少一个子时间单元中针对第二连接的传输配置为SBFD的子时间单元不用于下行接收。也就是说，针对第二连接，第一时间单元包括上行子时间单元、灵活子时间单元和/或不用于下行接收的SBFD子时间单元的情况下，终端设备在第一时间单元，通过第一连接发送第一信息时采用的发送功率限制为小于或等于第一功率。其中，SBFD子时间单元不用于下行接收指的是SBFD子时间单元不用于终端设备的下行接收，可以包括用于上行发送和/或灵活通信。
例如，以第一时间单元为时隙3为例。如图3C所示，时隙3包括符号0-符号13。其中，符号0-符号13中针对第二连接传输配置为下行的符号为符号7-9，符号0-符号13中针对第二连接传输配置为SBFD的符号为符号10-13，符号10-11用于下行接收，符号12-13用于上行发送，符号0-符号13中针对第二连接传输配置为灵活的符号为符号6，符号0-符号13中针对第二连接传输配置为上行的符号为符号0-5。也就是说，针对第二连接来说，符号0-5为上行符号，符号6为灵活符号、符号7-9为下行符号，符号10-13为SBFD符号。由于在符号0-6、符号12-13上终端设备可能会在第二连接上进行上行发送，因此当终端设备通过第一连接在时隙3上进行上行发送时的采用的发送功率小于或等于第一功率。
示例的，针对第二连接，第一时间单元仅包括下行子时间单元和/或用于下行接收的SBFD子时间单元的情况下，终端设备在第一时间单元通过第一连接发送第一信息时，可以不对第一信息的发送功率进行限制。从而有助于提高发送成功的可能性。
此外，在本申请的另一些实施例中，若第一时间单元针对第二连接的传输配置为下行，则第一信息的发送功率小于或等于第二功率。其中，第二功率为终端设备的最大总发送功率。第二功率大于第一功率。也就是说，若针对第二连接，第一时间单元为下行时间单元，终端设备在第一时间单元通过第一连接发送第一信息时采用的发送功率小于或等于第二功率。从而有助于提高终端设备的发送功率的利用率。其中，第一时间单元为下行时间单元指：第一时间单元包括的所有子时间单元均为下行子时间单元；或者，第一时间单元包括下行子时间单元和SBFD子时间单元，其中，第一时间单元中的所有SBFD子时间单元均用于下行接收。
例如，以第一时间单元为时隙4为例。如图3D所示，时隙4包括符号0-符号13。其中，针对第二连接的传输配置为下行的符号为符号0-13。也就是说，针对第二连接来说，符号0-13均为下行符号。由于在符号0-13上终端设备不会在第二连接上进行上行发送，因此当终端设备通过第一连接在时隙4上进行上行发送时的发送功率并非限制为小于或等于第一功率，而是限制为小于或等于第二功率。
又例如，以第一时间单元为时隙5为例。如图3E所示，时隙5包括符号0-符号13。其中，符号0-符号13中针对第二连接传输配置为下行的符号为符号0-9，符号0-符号13中针对第二连接传输配置为SBFD的符号为符号10-13，符号10-13均用于下行接收。也就是说，针对第二连接来说，符号0-9为下行符号，符号10-13为SBFD符号。由于在符号0-13上终端设备不会在第二连接上进行上行发送，因此当终端设备通过第一连接在时隙5上进行上行发送时的发送功率并非限制为小于或等于第一功率，而是限制为小于或等于第 二功率。
在本申请的一些实施例中，第一时间单元中针对第二连接的传输配置、和/或第一时间单元中SBFD子时间单元针对第二连接的传输方向可以为网络设备配置给终端设备的。
例如，在终端设备与第二网络设备之间的连接为第二连接的情况下，第二网络设备向终端设备指示第一时间单元中子时间单元针对第二连接的传输配置、和/或第一时间单元中SBFD子时间单元针对第二连接的传输方向。即，第二网络设备向终端设备发送第一指示信息和第二指示信息。该第一指示信息指示第一时间单元中SBFD子时间单元针对第二连接的传输方向。第二指示信息指示第一时间单元中子时间单元针对第二连接的传输配置。
其中，第二网络设备可以将第一指示信息和第二指示信息携带在同一信令或消息中发送给终端设备，或者，第二网络设备可以将第一指示信息和第二指示信息分别携带在不同的消息中发送给终端设备。例如，携带第一指示信息的消息可以为UE级的，携带第二指示信息的消息可以为小区级的。小区级的消息是针对小区内的所有终端设备有效的消息，UE级的消息是针对特定UE有效的消息。例如，小区级的消息可以为无线资源控制(Radio Resource Control，RRC)信令，UE级的消息可以为UE专用信令。
示例性的，如图3C所示，以第一时间单元为时隙3为例，时隙3包括符号0-符号13。第二指示信息可以指示如下内容：符号0-5针对第二连接的传输配置为上行，符号6针对第二连接的传输配置为灵活，符号7-9针对第二连接的传输配置为下行，符号10-13针对第二连接的传输配置为SBFD。进一步的，第一指示信息可以指示如下内容：符号0-符号13中，针对第二连接的传输配置为SBFD的符号10-11的传输方向为下行，针对第二连接的传输配置为SBFD的符号12-13的传输方向为上行，换言之，终端设备可以在符号10-11上通过第二连接进行下行接收，在符号12-13上通过第二连接进行上行发送。
例如，第一指示信息和第二指示信息携带在TDD-UL-DL-ConfigDedicated信令中，该TDD-UL-DL-ConfigDedicated信令为UE级的。
再例如，第一指示信息携带在TDD-UL-DL-ConfigDedicated信令中，TDD-UL-DL-ConfigDedicated信令为UE级的。第二指示信息携带在TDD-UL-DL-ConfigCommon信令，TDD-UL-DL-ConfigCommon信令为小区级的。
结合图4对本申请实施例的功率控制方法进行介绍。
如图4所示，时隙1、时隙2、时隙3、时隙4、时隙5和时隙6均包括针对第二连接的传输配置为SBFD的符号，时隙1、时隙2、时隙3、时隙4、时隙5和时隙6均包括14个符号，并且每个时隙中的前7个符号针对第二连接的传输配置均为下行，每个时隙中的后7个符号针对第二连接的传输配置均为SBFD。也就是说，针对第二连接来说，时隙1、时隙2、时隙3、时隙4、时隙5和时隙6中的前7个符号为下行符号，后7个符号为SBFD符号。其中，时隙1、时隙2、时隙3这三个时隙中包括的针对第二连接的传输配置为SBFD的符号均用于下行发送，时隙4、时隙5和时隙6这三个时隙中包括的针对第二连接的传输配置为SBFD的符号不用于下行发送。
在这种情况下，终端设备在时隙1、时隙2、时隙3、时隙4、时隙5和时隙6通过第一连接进行上行发送时采用的发送功率可以限制为小于或等于第一功率。或者，终端设备在时隙1、时隙2、时隙3通过第一连接进行上行发送采用的发送功率限制为小于或等于第二功率，在时隙4、时隙5和时隙6通过第一连接进行上行发送时采用的发送功率限制为小于或等于第一功率。由于在时隙1、时隙2、时隙3上终端设备不会在第二连接上进行上行发送，因此当终端设备通过第一连接在时隙1、时隙2、时隙3上进行上行发送时的发送功率并非限制为小于或等于第一功率，而是限制为小于或等于第二功率，有助于提高终端设备的发送功率的利用率。关于第一功率和第二功率可以参见上文的相关介绍，在此不再赘述。
