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。
如图1所示,为本申请实施例适用的一种可能的网络架构示意图,包括终端设备10和网络设备20。
其中,终端设备10的数量为两个或两上以上,且不同的终端设备间可以通过旁链路(sidelink,SL)传输旁链路信息,所述旁链路信息可包括数据(data)和/或调度分配(scheduling assigment,SA)。可选地,数据也可以称为数据信息,调度分配也可以称为调度分配信息。可选的,旁链路信息还可以包括旁链路反馈信息。比如,旁链路反馈信息可以包括信道状态信息(channel state information,CSI),混合自动重传请求(hybrid automatic repeat request,HARQ)信息等中的至少一种信息。其中,HARQ信息可以包括确认信息(acknowledgement,ACK)或否定性确认(negtive acknowledgement,NACK)。
终端设备10可以通过Uu空口向接入网设备传输上行信息,所述上行信息可包括上行数据信息和/或上行控制信息。其中,Uu空口可以理解为通用的UE和网络之间的接口(universal UE to network interface)。Uu空口的传输可以包括上行传输和下行传输。其中上行传输可以是指终端设备向接入网设备发送信号,下行传输可以是指接入网设备向终端设备发送信号。上行传输中所传输的信号可以称为上行信息或上行信号,下行传输中所传输的信号可以称为下行信息或下行信号。
在长期演进(long term evolution,LTE)系统中,存在SL传输与上行传输共存的场景。例如,在一个调度单位中,一个终端设备可以同时支持与接入网设备20进行上行传输和与其它的终端设备进行SL传输。为了降低多个发送端间的干扰,需要进行功率控制。
在LTE系统中,上行传输和SL传输的调度单位均为1个子帧。例如图2所示,SL data和SL SA可以采用频分复用方式,上行传输、SL SA和SL data在时域重叠。发送端可以采用如下方式,进行功率控制:确定上行传输和SL传输的优先级,然后根据优先级,调整上行传输、SL data和/或SL SA的发射功率,使三者的发射功率之和不超过终端设备的最大发射功率。比如,如果上行传输的优先级高于SL传输的优先级,那么,发送端可根据上行传输的发射功率,调整SL data和SL SA的发射功率,以使得三者的发射功率之和不超过最大发射功率。
在新空口(new radio,NR)系统中,提出了以下场景:Uu空口的上行传输的调度更加灵活,可以以符号为调度时间单元,且SL data与SL SA间的复用方式更灵活。其中,NR系统还可以称为第五代(5th generation,5G)移动通信系统。上行传输在时域上可仅与SL SA重叠,或者,仅与SL data重叠,或者,同时与SL SA和SL data重叠。在此场景下,如何进行功率控制,是本申请要解决的技术问题。
可选的,在图1所示的网络架构下,还可包括网管系统30。终端设备10可以通过有线接口或无线接口与网管系统30通信,比如在一种实现方式中,终端设备10可以通过接 入网设备20与网管系统30进行通信。在具体实现中,该网管系统30可以是运营商的网管系统。同理,网管系统30也可以通过有线接口或无线接口与终端设备10进行通信。比如,在一种实现方式中,网管系统30可以通过接入网设备20与终端10进行通信。
下面对本申请中所使用到的一些通信名词或术语进行解释说明,该通信名词或术语也作为本申请发明内容的一部分。

在下述图9至图16所示的示例中,以第一信息与第二信息的信息类型不同为例,进行说明。
如图9所示,旁链路传输中的旁链路信息包括SA和data,如果SA与data之间为TDM,在一个调度单位中,UL、SA和data在时域符号上有重叠,即目标信息中包括SA和data。SA符号上的发射功率为P SA,data符号上的发射功率比如为P data,P SA和P data可以相同或不同。如果SL传输的优先级高于上行传输时,第一终端设备可以确定第一发射功率,第一发射功率为P SA和P data中的较大值,进而可以根据第一发射功率,调整P UL的值。比如如果P SA>P data,则上行传输的功率调整需要满足P UL+P SA小于或等于第一终端设备的最大发送功率。如果P data>P SA,则上行传输的功率调整需要满足P UL+P data小于或等于第一终端设备的最大发射功率。如果上行传输的优先级高于SL传输,第一终端设备可以根据上行传输的功率调整第一发射功率。即第一终端设备可以根据上行传输的功率调整SA的发射功率和/或data的发射功率,保证SA的发射功率和data的发射功率中的最大值与上行传输的发射功率之和小于或等于UE的最大发送功率。比如如果P SA>P data,且P UL+P SA大于第一终端设备的最大发送功率,P UL+P data小于或等于第一终端设备的最大发送功率,则可以根据上行传输的功率调整SA的发射功率,且SA的功率调整需要满足P UL+P SA小于或等于第一终端设备的最大发送功率。比如如果P data>P SA,且P UL+P data大于第一终端设备的最大发送功率,P UL+P SA小于或等于第一终端设备的最大发送功率,则第一终端设备可以根据上行传输的功率调整data的发射功率,且data的功率调整需要满足P UL+P data小于或等于第一终端设备的最大发送功率。比如如果P UL+P data大于第一终端设备的最大发送功率,P UL+P SA大于第一终端设备的最大发送功率,则第一终端设备可以根据上行传输的功率调整SA的发射功率和data的发射功率,且SA的发射功率和data的发射功率的最大值需要满足P UL+max{P SA,P data}小于或等于第一终端设备的最大发送功率。
如图10、图11或图12所示,旁链路传输中的旁链路信息包括SA和data,如果SA与data之间为FDM,在一个调度单位中,UL、SA和data在时域符号上有重叠,即目标信息中包括SA和data。SA符号上的发射功率为P SA,data符号上的发射功率为P data,P SA和P data可以相同或不同。由于第一终端设备要同时发送SA和data,所述SL传输的总功率为SA和data的总功率之和,所述SL传输的总功率即为上述第一发射功率。如果SL传输的优先级高于上行传输,第一终端需要考虑SL的总功率,然后可以根据SL传输的总功率调整上行传输的功率值。比如,设计P SA+P data=P SL,则上行传输的功率调整需要满足P UL+P SL小于或等于第一终端备的最大发送功率。即上行传输的功率调整需要满足P UL+P SA+P data小于或等于第一终端设备的最大发送功率。如果上行传输的优先级高于SL传输,第一终端需要考虑上行传输的功率,然后可以根据上行传输的功率调整SA的发射功率和/或data的发射功率,且满足SL传输的总功率,即SA的发射功率和data的发射功率之和与上行功率之和小于或等于第一终端设备的最大发送功率。比如,设计P SA+P data=P SL,则旁链路传输的总功率调整需要满足P UL+P SL小于或等于第一终端设备的最大发送功率。即旁链路传输的功率调整需要满足P UL+P SA+P data小于或等于第一终端设备的最大发送功率。
如图13所示,旁链路传输中的旁链路信息包括SA、data和SFCI,在一个调度单位内,UL与data,和SFCI存在时域重叠,且data和SFCI两者是TDM模式。设定data符号上的功率为P data,SFCI上的功率为P SFCI。当SL传输的优先级高于上行传输的优先级时,需要考虑SFCI和data,两者之间的最大功率(即为上述第一发射功率),然后根据该最大功率调整上行传输的功率值。如果P SFCI>P data,则上行传输的功率调整需要满足P UL+P SFCI小于或等于第一终端设备的最大发送功率。如果P data>P SFCI,则上行传输的功率调整需要满足 P UL+P data小于或等于第一终端设备的最大发送功率。当上行传输的优先级高于SL传输的优先时级,需要考虑上行传输的功率,调整SFCI的功率和/或data的功率,保证两者之间的最大功率与上行传输的功率之和小于或等于第一终端设备的最大发送功率。即第一终端设备可以根据上行传输的功率调整SFCI的发射功率和/或data的发射功率,保证SFCI的发射功率和data的发射功率的最大值与上行传输的发射功率之和小于或等于第一终端设备的最大发送功率。比如,如果P SFCI>P data,且P UL+P SFCI大于UE的最大发送功率,P UL+P data小于或等于UE的最大发送功率,则第一终端设备可以根据上行传输的功率调整SFCI的发射功率P SFCI,且SFCI的功率调整需要满足P UL+P SFCI小于或等于第一终端设备的最大发送功率。如果P data>P SFCI,且P UL+P data大于第一终端设备的最大发送功率,P UL+P SFCI小于或等于第一终端设备的最大发送功率,则第一终端设备可以根据上行传输的功率调整data的发射功率P data,且data的功率调整需要满足P UL+P data小于或等于第一终端设备的最大发送功率。比如如果P UL+P data大于第一终端设备的最大发送功率,P UL+P SFCI大于第一终端设备的最大发送功率,则第一终端设备可以根据上行传输的功率调整SFCI的发射功率和data的发射功率,且SFCI的发射功率和data的发射功率的最大值需要满足P UL+max{P SFCI,P data}小于或等于第一终端设备的最大发送功率。可以理解的是,由于SFCI可以在PSFCH中传输,所述SFCI的发射功率,也可称为PSFCH的发射功率。类似的,由于SL UCI可以在PSUCCH中传输,所述SL UCI的发射功率,也可称为PSUCCH的发射功率。
如图14所示,旁链路传输中的旁链路信息包括SA、data和SFCI,在一个调度单位中,UL、data和SFCI时域重叠,且data和SFCI两者采用FDM模式。设定data符号上的功率为P data,SFCI的功率为P SFCI,则当SL传输的优先级高于上行传输的优先级时,需要考虑SFCI和data的发射功率之和(即为上述第一发射功率),然后根据该功率调整上行传输的功率值,比如上行传输的功率调整需要满足P UL+P data+P SFCI小于或等于第一终端设备的最大发送功率。当上行传输的优先级高于SL传输的优先级时,需要考虑上行传输的发射功率,然后根据上行传输的功率调整SFCI的发射功率和/或data的发射功率,且两者发射功率之和的调整需要满足P UL+P data+P SFCI小于或等于第一终端设备的最大发送功率。
如图15所示,旁链路传输中的旁链路信息包括SA、data和SFCI,在一个调度单位内,UL和SA,SFCI时域重叠,且SA和SFCI两者是TDM模式。当SL传输的优先级高于上行传输的优先级时,需要考虑SFCI和SA两者之间的最大功率(即上述第一发射功率),然后根据该最大功率调整上行传输的功率值。例如,如果P SFCI>P SA,则上行传输的功率调整需要满足P UL+P SFCI小于或等于第一终端设备的最大发送功率。如果P SA>P SFCI,则上行传输的功率调整需要满足P UL+P SA小于或等于第一终端设备的最大发送功率。当上行传输的优先级高于SL传输的优先级时,需要考虑上行传输的功率,然后根据上行传输的功率调整SFCI的发送功率和/或SA的发送功率,且调整需要满足两者之间的最大功率和上行传输的功率之和小于或等于第一终端设备的最大发送功率。即第一终端设备可以根据上行传输的功率调整SFCI的发射功率和/或SA的发射功率,保证SFCI的发射功率和SA的发射功率的最大值与上行传输的发射功率之和小于或等于第一终端设备的最大发送功率。比如,P SFCI>P SA,且P UL+P SFCI大于第一终端设备的最大发送功率,P UL+P SA小于或等于第一终端设备的最大发送功率,则根据上行传输的发射功率,调整SFCI的发射功率,且SFCI的功率调整需要满足P UL+P SFCI小于或等于第一终端设备的最大发送功率。如果P SA>P SFCI,且P UL+P SA大于第一终端设备的最大发送功率,P UL+P SFCI小于或等于第一终端设备的最大 发送功率,则根据上行传输的发射功率,调整SA的发射功率,且SA的功率调整需要满足P UL+P SA小于或等于第一终端设备的最大发送功率。比如如果P UL+P SA大于第一终端设备的最大发送功率,P UL+P SFCI大于第一终端设备的最大发送功率,则第一终端设备可以根据上行传输的功率调整SFCI的发射功率和SA的发射功率,且SA的发射功率和SFCI的发射功率的最大值需要满足P UL+max{P SA,P SFCI}小于或等于第一终端设备的最大发送功率。可以理解的是,由于SFCI可以在PSFCH中传输,所述SFCI的发射功率,也可称为PSFCH的发射功率。
如图16所示,旁链路传输中的旁链路信息包括SA、data和SFCI,在一个调度单位内,UL和SA,SFCI时域重叠,且SA和SFCI两者是FDM模式。如果SL传输的优先级高于上行传输的优先级时,需要考虑P SFCI和P SA的发射功率之和(即为上述第一发射功率),然后根据该功率之和调整上行传输的功率值。例如,上行传输的功率调整需要满足P UL+P SA+P SFCI小于或等于第一终端设备的最大发送功率。如果上行传输的优先级高于SL传输的优先级,需要考虑上行传输的发射功率,可以根据上行传输的发射功率调整P SFCI的发射功率和/或P SA的发射功率,且P SFCI和P SA的发射功率之和需要满足P UL+P SA+P SFCI小于或等于第一终端设备的最大发送功率。

如图23所示,旁链路传输中的旁链路信息包括data,在一个调度单位中,UL和两个data时域重叠,且两个data采用TDM模式。如果SL传输的优先级高于上行传输的优先级,需要计算两个data发射功率中的较大值,根据该较大值,调整UL的发射功率。如果上行传输的优先级高于SL传输的优先级,根据UL的发送功率,调整两个data发射功率中的至少一个,且满足两个data发射功率中的较大值与上行传输的发射功率之和小于或等于第一终端设备的最大发射功率。
