Description

一种功率确定方法及通信装置
本申请要求于2021年11月22日提交中国专利局、申请号为202111389856.9、申请名称为“一种功率确定方法及通信装置”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，尤其涉及一种功率确定方法及通信装置。
背景技术
目前的无线通信系统，例如WiFi，长期演进(long term evolution，LTE)都是基于半双工传输，即同一个设备在同一个载波或相同的时频资源上不允许同时进行收发操作。近期，第三代合作伙伴计划(3rd generation partnership project，3GPP)全会提出子带全双工(subband full duplex，SBFD)，将工作于半双工的终端设备进行联合调度，使得网络设备(如基站)能同时进行收发，在网络设备侧实现全双工。网络设备侧进行的全双工为子带全双工，即在同一载波的不同子带上同时进行发送和接收。子带全双工也可称为时频分双工(X division duplex，XDD)，或全双工等。例如，如图1所示，对于某一时分双工下行(time division duplex downlink，TDD DL)时隙(slot)，可以在该slot中选取部分子带用作上行(uplink，UL)传输。即在非对称频谱(unpaired spectrum，通常指TDD)上使能频分双工(frequency division duplex，FDD)传输。
SBFD时隙中的下行用户设备(downlink user equipment，DL UE)不同，会对SBFD时隙中的UL UE造成不同的干扰。目前的功率控制并非针对SBFD传输，因此，不精确的功率调整信息会导致上行传输受到强烈的自干扰，导致全双工的增益降低。
发明内容
本申请提供一种功率确定方法及通信装置，有利于避免上行传输受到强烈的自干扰，避免降低全双工的增益。
第一方面，本申请提供了一种功率确定方法，应用于第一终端设备，该方法包括：
接收第一信令，该第一信令包括第一信息和第二信息，该第一信息指示第一全双工时间单元，该第二信息指示第一上行传输的第一功率调整信息，该第一上行传输为位于第一全双工时间单元的上行传输；根据第一信令，确定第一上行传输的发射功率。
基于第一方面所描述的方法，第一终端设备能够及时地接收到第一信令来确定第一终端设备在第一全双工时间单元内的第一上行传输的发射功率，有利于避免第一上行传输受到强烈的自干扰，避免降低全双工的增益。
可选的，第一信令不用于调度。可选的，第一信令不包括上行调度信息或下行调度信息。
在一种可能的实现中，在第一全双工时间单元上，存在至少两个子带，至少两个子带中的两个子带的传输方向不同；其中，两个子带在频域上不重叠、部分重叠或完全重叠。通过在同一时间单元上引入不同的传输方向，使得在用于下行传输的载波上或者用于灵活符号的载波上，可以进行上行传输。从而使得上行容量得到扩展，减少了终端设备进行上行传输所 需要的时延，等待时间更短，加速了通信，保证了服务质量。
在一种可能的实现中，第一终端设备还可接收第二信令，该第二信令包括第三信息和第四信息，该第三信息指示第一全双工时间单元，该第四信息指示第一上行传输的第二功率调整信息，该第二信令不包括上行调度信息或下行调度信息；根据第一信令，确定第一上行传输的发射功率的具体实施方式为：根据第一信令和第二信令，确定第一上行传输的发射功率。
基于该可能的实现方式，网络设备可以分多次向第一终端设备下发第一上行传输的功率调整信息。如果网络设备确定完第一全双工时间单元内所有用于下行传输的终端设备之后，才向第一终端设备下发第一上行传输的功率调整信息，网络设备可能面临没有充足的下发资源用于功率调整信息的发送，或者不能保证第一终端设备在接收第一上行传输的功率调整信息之后，有足够的时间确定和调整第一上行传输的发射功率。因此，可能造成第一终端设备无法对第一上行传输进行有效的功率弥补，无法缓解第一上行传输在网络设备处遭受的自干扰影响，第一上行传输无法被网络设备正确接收。而如果网络设备分多次向第一终端设备下发第一上行传输的功率调整信息，网络设备在确定有下行传输会对第一上行传输会产生自干扰影响时，就可及时下发第一上行传输的功率调整信息，可以保证有充足的下发资源用于功率调整信息的发送，保证第一终端设备在接收第一上行传输的功率调整信息之后，有足够的时间确定和调整第一上行传输的发射功率。因此，有利于第一终端设备对第一上行传输进行有效的功率弥补，缓解第一上行传输在网络设备处遭受的自干扰影响，使得第一上行传输被网络设备正确接收。
在一种可能的实现中，第一终端设备接收第一信令之前，还可接收第三信令；该第三信令包括第一上行传输的调度信息，该第一上行传输的调度信息指示第一上行传输的第三功率调整信息；或者，该第三信令包括第一下行传输的调度信息，第一上行传输用于传输第一下行传输的反馈信息，该第一下行传输的调度信息指示第一上行传输的第三功率调整信息；第一终端设备根据第一信令，确定第一上行传输的发射功率的具体实施方式为：根据第一信令和第三信令，确定第一上行传输的发射功率。在该可能的实现方式中，第一功率调整信息可以是相对于第三功率调整信息的偏移量，通过指示相对于第三功率调整信息的偏移量有助于减少第一信令的开销，可以减少第一信令的比特数，最小化成本。
可选的，调度信息指用于传输数据的时域或频域资源分配信息，调制编码信息，HARQ进程号信息，上行探测信号触发信息，待传输数据的反馈信息，待传输数据的反馈资源信息，或待传输数据的功率参数信息等中至少一项。
在一种可能的实现中，第一终端设备还可接收第四信令，该第四信令包括第二上行传输的调度信息，或，该第四信令包括第二下行传输的调度信息，第二上行传输用于传输第二下行传输的反馈信息；根据第三信令和第四信令，确定第二上行传输的发射功率，该第二上行传输在时域上位于第一上行传输之后。基于该可能的实现方式，可以避免在对第一全双工时间单元内的第一上行传输的发射功率进行调整之后，影响第一上行传输之后的上行传输的发射功率。基于该可能的实现方式，可以有针对性的对某个全双工时间单元内的上行传输的发射功率进行调整。
在一种可能的实现中，第一信令为在T2-Δt之前传输的信令，T2为第一全双工时间单元，Δt为第一上行传输的功率调整时延。基于该可能的实现方式，能够保证第一终端设备有足够的时间确定和调整第一上行传输的发射功率。
在一种可能的实现中，第一功率调整信息包括第一上行传输的传输功率控制TPC和/或第一上行传输的目标功率。
在一种可能的实现中，第一信令可以是组公共控制信令。由于组公共控制信令是发给一组终端设备的，而不是用户特定的(UE-specific)，避免了网络设备为终端设备组中的每个终端设备分别生成不同的信令造成信令开销大的问题，降低了网络设备的信令开销。
在一种可能的实现中，第一信令可以是专用控制指令。
在一种可能的实现中，组公共控制信令的循环冗余码校验CRC部分通过组公共的无线网络临时标识RNTI加扰。这样这一个用户组内所有终端设备都可以用这个RNTI去解扰组公共控制信令。
在一种可能的实现中，第一信令为组公共控制信令，第二信息包括N个子带的功率调整信息域，第一上行传输位于N个子带中的一个或多个子带，N为大于1的整数。基于该可能的实现方式，能够准确地向多个终端设备指示其对应的功率调整信息。
在一种可能的实现中，第一信息包括从T1到T2的时间单元偏移量，T1为传输第一信令的时间单元，T2为第一全双工时间单元。通过T1到T2的时间单元偏移量来指示第一全双工时间单元，可以有效指示第一全双工时间单元，使得第一终端设备能获知准确应用第一功率调整信息的时间单元，且通过T1到T2的时间单元偏移量来指示第一全双工时间单元，有助于减少第一信令的开销，可以减少第一信令的比特数，最小化成本。
可选的，T1到T2的时间单元偏移量可以为时隙偏移量。可选的，T1到T2的时间单元偏移量也可以为符号偏移量。
在一种可能的实现中，第一信令为专用控制信令，第一信息包括混合自动重传请求HARQ进程号，该HARQ进程号对应第一全双工时间单元。HARQ进程号对应时间单元，表示HARQ进程号对应的数据传输位于该时间单元。第一终端设备基于有效时段内的HARQ进程，能确定某个HARQ进程号对应的数据传输所在的时间单元。所述有效时段指的是最大个数HARQ进程可以持续的调度时间，通过限制基于有效时段内的HARQ进程来确定某个HARQ进程号对应的数据传输所在的时间单元，可以保证终端设备不会产生混淆，不会出现对多个持有相同HARQ进程号的数据无法准确区分和适用的情形。通过HARQ进程号来指示第一全双工时间单元，可以在不引入任何新的参考信息的情况下指示第一全双工时间单元。
第二方面，本申请提供了一种功率确定方法，应用于第二终端设备，该方法包括：接收第一信令，该第一信令包括第一信息和第二信息，该第一信息指示第一全双工时间单元，该第二信息指示第一上行传输的第一功率调整信息，该第一上行传输为位于第一全双工时间单元的上行传输；接收第五信令，该第五信令包括第三上行传输的调度信息，或，该第五信令包括第三下行传输的调度信息，该第三上行传输用于传输第三下行传输的反馈信息，该第三上行传输位于第二全双工时间单元；确定第三上行传输的发射功率；其中，第二全双工时间单元不同于第一全双工时间单元，第一信令不用于确定第三上行传输的发射功率。
基于第二方面所描述的方法，第二终端设备在接收到组播的第一信令之后，如果第二终端设备中的上行传输不在第一信令指示的全双工时间单元内，则不使用该第一信令来确定该上行传输的发射功率，这样第二终端设备可以准确地确定上行传输的发射功率。
可选的，第一信令不用于调度。可选的，第一信令不包括上行调度信息或下行调度信息。
在一种可能的实现中，第二终端设备接收第五信令之后，当第二全双工时间单元不同于第一全双工时间单元时，确定第一信令不用于确定第三上行传输的发射功率。
在一种可能的实现中，在第一全双工时间单元或第二全双工时间单元上，存在至少两个子带，至少两个子带中的两个子带的传输方向不同；其中，两个子带在频域上不重叠、部分重叠或完全重叠。

在全双工时间单元上，存在至少两个子带，该至少两个子带中的两个子带的传输方向不同。其中，该两个子带在频域上不重叠、部分重叠或完全重叠。也就是说，全双工为不重叠的子带上的全双工，或者，全双工为部分重叠的子带上的全双工，或者，全双工为完全重叠的子带上的全双工。通过在同一时间单元上引入不同的传输方向，使得在用于下行传输的载波上或者用于灵活符号的载波上，可以进行上行传输。从而使得上行容量得到扩展，减少了终端设备进行上行传输所需要的时延，等待时间更短，加速了通信，保证了服务质量。
例如，以两个子带在频域上不重叠为例。在全双工时间单元上，存在子带1和子带2。子带1用于上行传输，子带2用于下行传输。子带1包括PRB#0～PRB#9，子带2包括PRB#10～PRB#19。
再如，以两个子带在频域上部分重叠为例。在全双工时间单元上，存在子带1和子带2。子带1用于上行传输，子带2用于下行传输。子带1包括PRB#0～PRB#9，子带2包括PRB#5～PRB#14。
再如，以两个子带在频域上完全重叠为例。在全双工时间单元上，存在子带1和子带2。子带1用于上行传输，子带2用于下行传输。子带1包括PRB#0～PRB#9，子带2包括PRB#0～PRB#9。
四、闭环功率控制
终端设备基于网络设备配置的闭环功率控制参数来确定上行传输的发射功率。例如，以上行传输为PUSCH为例。下面对如何基于闭环功率控制参数确定PUSCH的发射功率进行介绍：
需要说明的是，下文中描述的PUSCH的发射功率可以认为是终端设备在资源单位i向小区c发送PUSCH的发射功率。其中，资源单位i可以是任一个资源单位，小区c可以是网络设备，例如基站，所服务的任一个小区。为了便于描述，下文中计算的PUSCH的发射功率的公式中均未涉及c。
终端设备在资源单位i发射PUSCH的发射功率P(i,j,q d,n)为：
Figure PCTCN2022131012-appb-000001
其中，j为配置{P 0，α}参数集的索引；n为配置的功率控制调整状态索引，对应不同的闭环功率控制进程，n可以为1或2；q d为参考信号(reference signal，RS)资源索引；P CMAX(i)为终端设备的最大可用发射功率；M RB(i)是资源单位i内PUSCH对应的时频资源所占的带宽，该时频资源可以以资源块(resource block，RB)数目为单位。α(j)为半静态配置参数，表示路损补偿程度。PL(q d)为UE估计的路损值；Δ TF(i)为针对不同调制与编码策略(modulation and coding scheme，MCS)索引的增量值。P 0(j)为半静态配置的功控参数，表示终端设备的目标功率，由小区级功控参数和终端设备级功控参数组成。f(i,n)为终端设备特定的闭环功率控制参数。其中，传输功率控制(transmission power control，TPC)为闭环功率控制参数的一种。
网络设备可通过配置上述目标功率和闭环功率控制参数来配置上行发射功率。例如，网络设备可以通过无线资源控制(radio resource control，RRC)信令为终端设备配置一个或多个目标功率。如果网络设备为终端设备配置了多个目标功率，则网络设备可通过DCI信令动态指示终端设备采用该多个目标功率中的哪个目标功率计算上行发射功率。如果网络设备只为终端设备配置了一个目标功率，则网络设备无需再通过DCI信令指示目标功率，终端设备可以直接使用RRC信令配置的目标功率来计算上行发射功率。
再如，网络设备可通过DCI信令动态指示终端设备采用哪个闭环功率控制参数计算上行发射功率闭环功率控制参数。闭环功率控制有绝对式(绝对调整)和累积式(相对调整)之说。DCI信令指示的闭环功率控制参数可以是一个绝对值或者是一个偏移量。
以闭环功率控制参数为TPC为例。绝对式功率控制中的“绝对”体现在：f(i)＝TPC。即第i个DCI信令指示的TPC就为终端设备计算上行传输的发射功率使用的TPC。
举例来说，如图4所示，假设时隙1～时隙6是正常的时隙，为非全双工时隙。时隙1～时隙3为下行时隙，时隙4～时隙6为上行时隙。网络设备在时隙1向终端设备1下发了DCI信令1，该DCI信令1用于调度PUSCH1在时隙4传输。网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙5传输。网络设备在时隙3向终端设备1下发了DCI信令3，该DCI信令3用于调度PUSCH3在时隙6传输。DCI信令1指示10db的TPC。DCI信令2指示11db的TPC。DCI信令3指示13db的TPC。终端设备1在时隙4使用10db的TPC来计算PUSCH1的发射功率。终端设备1在时隙5使用11db的TPC来计算PUSCH2的发射功率。终端设备1在时隙6使用13db的TPC来计算PUSCH3的发射功率。本申请实施例中的所有举例中的TPC的值均为示例，不构成对本申请实施例的限定。
累积式功率控制中的“累积”体现在：f(i)＝f(i-1)+TPC。即第i个DCI信令指示的 TPC为相对于第i-1个DCI信令指示的TPC的偏移量。网络设备下发的第i个DCI信令指示的TPC，需要叠加在上次功率控制调整的TPC(即f(i-1))上面，累加后的TPC(即f(i))才是终端设备计算上行传输的发射功率使用的TPC。相应的，上次功率控制调整的TPC(即f(i-1))需要叠加在上上次功率控制调整的TPC(即f(i-2))上面，所以f(i)是一个依次累加的值。
举例来说，如图4所示，DCI信令1指示10db的TPC。DCI信令2指示1db的TPC，该DCI信令2指示的TPC为相较于DCI信令1指示的TPC的偏移量。DCI信令3指示2db的TPC，DCI信令3指示的TPC为相较于DCI信令2指示的TPC的偏移量。终端设备1在时隙4使用10db的TPC来计算PUSCH1的发射功率。终端设备1在时隙5使用11db的TPC来计算PUSCH2的发射功率。终端设备1在时隙6使用13db的TPC来计算PUSCH3的发射功率。
五、组公共控制信令
组公共控制信令是发送给用于一组终端设备的控制信令。组公共控制信令的循环冗余码校验(cyclic redundancy check，CRC)部分通过组公共的无线网络临时标识(radio network temporary identifier，RNTI)加扰。这样这一个用户组内所有终端设备都可以用这个RNTI去解扰组公共控制信令。或者说，被配置了该RNTI的一组用户，都可以用这个RNTI去解扰组公共控制信令。组公共控制信令可以是组公共DCI信令，或者是其他的组公共控制信令。
六、专用控制信令
专用控制信令是发送给一个终端设备的控制信令。专用控制信令可以是专用DCI信令，或者是其他的专用控制信令。专用DCI信令可以理解为调度某UE的DCI信令。
七、功率爬坡值
在无线通信系统中，终端设备和网络设备建立连接，这一过程通常被称为随机接入(random access，RA)过程。从终端设备的角度上看，随机接入过程可能遇到各种问题导致随机接入失败。如果本次随机接入失败了，则终端设备会重新发起随机接入，并进行功率爬坡(power ramping)，即使用比上次随机接入更高的功率去发起本次随机接入。该功率爬坡增加的功率可以称为功率爬坡值。
第五代新空口(5th generation new radio，5G NR)技术中，上行和下行调度有不同的时序(timing)要求。例如，如图5所示，k 0为从传输用于调度物理下行数据信道(physical downlink data channel，PDSCH)的下行控制信息(downlink control information，DCI)信令的下行时隙到传输该PDSCH的下行时隙之间的偏移量(offset)。k 1为从传输该PDSCH的下行时隙到传输该PDSCH的反馈信息的上行时隙之间的偏移量。该PDSCH的反馈信息可以为确定应答/否定应答(acknowledgement/negative-acknowledgement，ACK/NACK)。用于调度PDSCH的DCI信令中包括了承载该反馈信息的物理上行控制信道(physical uplink control channel，PUCCH)的功率调整信息。该功率调整信息用于确定该PUCCH的发射功率。例如，图6所示，k 2为从传输用于调度物理上行数据信道(physical uplink data Channel，PUSCH)的DCI信令的下行时隙到传输该PUSCH的上行时隙之间的偏移量。用于调度PUSCH的DCI信令中包括了该PUSCH的功率调整信息。该功率调整信息用于确定该PUSCH的发射功率。
SBFD时隙中的下行用户设备(downlink user equipment，DL UE)不同，会对SBFD时隙中的UL UE造成不同的干扰。因此，SBFD时隙中的DL UE不同，UL UE在SBFD中应该使用不同的功率调整信息来确定上行传输的发射功率，以减小邻信道对上行传输的干扰。由 于通常k 0小于k 2，即SBFD时隙中的UL UE的调度时间在DL UE的调度时间之前。这就导致网络设备在通过DCI信令调度SBFD时隙中的UL UE时，无法确定SBFD时隙中与UL UE配对的DL UE。因此，DCI信令中包括的上行传输的功率调整信息并不准确。例如，如图7所示，在时隙n-t1时，会传输用于调度PUSCH的DCI信令。该DCI信令用于调度该PUSCH在时隙n发送，该DCI信令中包括该PUSCH的功率调整信息，时隙n为SBFD时隙。由于在时隙n-t1，网络设备仍然未决定在时隙n中调度哪个DLUE进行下行传输，网络设备不确定时隙n的上行传输将面临的干扰。因此，时隙n的PUSCH的功率调整信息不能被正确设置。不精确的功率调整信息会导致上行传输受到强烈的自干扰，导致全双工的增益降低。
为避免上行传输受到强烈的自干扰，避免降低全双工的增益，本申请提供了一种功率确定方法及通信装置。
下面进一步对本申请实施例提供的功率确定方法及通信装置进行详细描述。
图8是本申请实施例提供的一种功率确定方法的流程示意图。如图8所示，该功率确定方法包括如下步骤801～步骤803。图8所示的方法执行主体可以为第一终端设备和网络设备。或者，图8所示的方法执行主体可以为第一终端设备中的芯片和网络设备中的芯片。图8以第一终端设备和网络设备为方法的执行主体为例进行说明。
801、网络设备确定第一信息和第二信息。
其中，该第一信息指示第一全双工时间单元，该第二信息指示第一上行传输的第一功率调整信息，该第一上行传输为位于第一全双工时间单元的上行传输。关于全双工时间单元的描述可参见前文专业术语的相关描述，在此不赘述。
本申请中，功率调整信息也可以理解为功率确定信息，功率控制信息或者功率弥补信息。
在一种可能的实现中，第一上行传输可以为上行信号的传输或物理上行信道的传输或物理上行信道上所承载的传输。例如，上行信号的传输包括探测参考信号(sounding reference signal，SRS)的传输。物理上行信道的传输包括PUSCH的传输或PUCCH的传输。物理上行信道上所承载的传输包括PUSCH上所承载的传输、PUCCH上所承载的传输或PUSCH上所承载的上行控制信息(uplink control information,UCI)的传输。
本申请实施例中，网络设备还可在确定第一信息和第二信息之前，向第一终端设备发送第三信令。相应地，第一终端设备可以接收该第三信令。该第三信令可以为DCI信令。其中，该第三信令包括第一上行传输的调度信息，第一上行传输的调度信息包括第一上行传输的第三功率调整信息；或者，该第三信令包括第一下行传输的调度信息，第一上行传输用于传输第一下行传输的反馈信息，第一下行传输的调度信息包括第一上行传输的第三功率调整信息。
如果该第三信令包括第一上行传输的调度信息，即第三信令用于调度第一上行传输。作为示例，第一上行传输包括SRS的传输、PUSCH的传输或PUSCH上所承载的传输。如果该第三信令包括第一下行传输的调度信息，即第三信令用于调度第一下行传输。作为示例，第一下行传输包括PDSCH的传输或PDSCH上所承载的传输。这种情况下，第一上行传输为PUCCH或PUCCH上所承载的传输。或者，第一上行传输为PUSCH上所承载的UCI的传输。
在另一种可能的实现中，网络设备也可以不发送第三信令，网络设备可在确定第一信息和第二信息之前，向第一终端设备发送非授权(grant free)调度信令。该非授权调度信令包括第一上行传输的调度信息。相应地，第一终端设备可以接收该非授权调度信令。其中，非授权调度信令可以为RRC信令，或者通过DCI触发的RRC信令。通过DCI触发的RRC信令也可以理解为RRC信令结合DCI信令。RRC信令非授权调度可以为type I的非授权调度。RRC信令结合DCI信令的非授权调度可以为type II的非授权调度。作为示例，第一上行传输 包括SRS的传输、PUSCH的传输、PUSCH上所承载的传输、PUCCH的传输、PUCCH上所承载的传输或PUSCH上所承载的UCI的传输。
如果网络设备向第一终端设备发送非授权调度信令，网络设备还可向第一终端设备发送一个DCI信令，该DCI信令携带第一上行传输的第三功率调整信息。相应地，第一终端设备可以接收该DCI信令。
在一种可能的实现中，第三功率调整信息包括第一上行传输的TPC和/或第一上行传输的目标功率。或者，第三功率调整信息还可以是其他用于确定第一上行传输的发射功率的参数。第三功率调整信息中的TPC可以是绝对值或者是偏移量。基于前文中对闭环功率控制的描述可知，如果是绝对式功率控制，第三功率调整信息中的TPC是绝对值。如果是累积式功率控制，则第三功率调整信息中的TPC是偏移量。
在一种可能的实现中，第一功率调整信息包括第一上行传输的TPC和/或第一上行传输的目标功率。或者，第一功率调整信息还可以是其他用于确定第一上行传输的发射功率的参数。第一功率调整信息中的TPC或目标功率可以是绝对值或者是偏移量。如果第一功率调整信息中的TPC或目标功率是偏移量有利于减少第一信令的开销，可以减少第一信令的比特数，最小化成本。
可选的，如果第一功率调整信息中的TPC是一个偏移量，第一功率调整信息中的TPC可以是相对于第三功率调整信息中的TPC的偏移量。
可选的，如果第一功率调整信息中的目标功率是一个偏移量，第一功率调整信息中的目标功率可以是相对于第三功率调整信息中的目标功率的偏移量。
可选的，如果RRC信令只配置了一个目标功率值，如果第一功率调整信息中的目标功率是一个偏移量，第一功率调整信息中的目标功率可以是相对于RRC信令指示的目标功率的偏移量。
在一种可能的实现中，第一终端设备可以基于第一信令和第三信令来确定第一上行传输的发射功率。
例如，如果第一功率调整信息中的TPC是相对于第三功率调整信息中的TPC的偏移量。第一终端设备可以将第一功率调整信息中的TPC和第三功率调整信息中的TPC进行叠加，并基于叠加之后的TPC来计算第一上行传输的发射功率。同理，如果第一功率调整信息中的目标功率是相对于第三功率调整信息中的目标功率的偏移量。第一终端设备可以将第一功率调整信息中的目标功率和第三功率调整信息中的目标功率进行叠加，并基于叠加之后的目标功率来计算第一上行传输的发射功率。
举例来说，以第三功率调整信息中的TPC为偏移量为例。作为示例，如图9所示，时隙1～时隙5和时隙7是正常的时隙，为非全双工时隙。时隙6为全双工时隙。当然，时隙1～时隙5和时隙7也可以不全都是非全双工时隙，即其中的一个或多个时隙也可以为全双工时隙。网络设备在时隙1向终端设备1下发了DCI信令1，该DCI信令1用于调度PUSCH1在时隙5传输，该DCI信令1指示的TPC为10db，该DCI信令1指示的目标功率为12db。
网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输，该DCI信令2指示的TPC为2db，该DCI信令2指示的TPC为相较于DCI信令1指示的TPC的偏移量。该DCI信令2指示的目标功率为14db。
网络设备在时隙4确定在时隙6要调度终端设备2和终端设备3进行下行传输，此时，考虑到终端设备2和终端设备3在时隙6对PUSCH2会产生自干扰，网络设备确定DCI信令2指示的TPC和/或目标功率已不准确，会造成偏差。因此，网络设备在时隙4向终端设备1 下发DCI信令3，该DCI信令3指示2db的TPC以及该TPC应用的时隙6；或者，该DCI信令3指示3db的目标功率以及该目标功率应用的时隙6；或者，该DCI信令3指示2db的TPC和3db的目标功率以及该TPC和目标功率应用的时隙6。该DCI信令3指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令3指示的目标功率为相较于DCI信令2指示的目标功率的偏移量。
如果DCI信令3指示2db的TPC以及该TPC应用的时隙6，终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC以及DCI信令3指示的TPC进行累计。得到累计后的TPC为14db。第一终端设备使用14db的TPC来计算PUSCH2的发射功率。
如果DCI信令3指示3db的目标功率以及该目标功率应用的时隙6，终端设备1将DCI信令2指示的目标功率以及DCI信令3指示的目标功率进行累计。得到累计后的目标功率为17db。第一终端设备使用17db的目标功率来计算PUSCH2的发射功率。
如果DCI信令3指示2db的TPC和3db的目标功率以及该TPC和目标功率应用的时隙6。终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC以及DCI信令3指示的TPC进行累计。得到累计后的TPC为14db。终端设备1将DCI信令2指示的目标功率以及DCI信令3指示的目标功率进行累计。得到累计后的目标功率为17db。第一终端设备使用14db的TPC和17db的目标功率来计算PUSCH2的发射功率。
本申请实施例中的所有举例中的TPC的值和目标功率的值均为示例，不构成对本申请实施例的限定。
本申请中，当频段完全重叠时，自干扰可以是同时同频的发送对接收产生的干扰；当频段不重叠时，自干扰可以是同时不同频的发送对接收产生的邻信道干扰；当频段部分重叠时，自干扰可以既包含同时同频的发送对接收产生的干扰，又包含同时不同频的发送对接收产生的邻信道干扰。本申请中，自干扰也可以理解为非线性干扰。
再举例来说，以第三功率调整信息中的TPC为绝对值为例。如图9所示，网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输，该DCI信令2指示的TPC为12db，该DCI信令2指示的目标功率为14db。
网络设备在时隙4确定在时隙6要调度终端设备2和终端设备3进行下行传输，此时考虑到终端设备2和终端设备3在时隙6对PUSCH2会产生自干扰，网络设备认为DCI信令2指示的TPC和/或目标功率已不准确，会造成偏差。因此，网络设备在时隙4向终端设备1下发DCI信令3，该DCI信令3指示2db的TPC和/或3db的目标功率，以及指示该TPC和/或该目标功率应用的时隙6。该DCI信令3指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令3指示的目标功率为相较于DCI信令2指示的目标功率的偏移量。
终端设备1将DCI信令2指示的TPC以及DCI信令3指示的TPC进行累计，得到累计后的TPC为14db，和/或，终端设备1将DCI信令2指示的目标功率以及DCI信令3指示的目标功率进行累计，得到累计后的目标功率为17db。第一终端设备使用14db的TPC和/或17db的目标功率来计算PUSCH2的发射功率。
在一种可能的实现中，如果第一功率调整信息中的目标功率是相对于RRC信令指示的目标功率的偏移量。第一终端设备可以将第一功率调整信息中的目标功率和RRC信令指示的目标功率进行叠加，并基于叠加之后的目标功率来计算第一上行传输的发射功率。
例如，假设RRC信令指示的目标功率为10db，第一功率调整信息中的目标功率为2db，则第一终端设备将RRC信令指示的目标功率与第一功率调整信息中的目标功率进行叠加，得到叠加后的目标功率为12db。第一终端设备基于12db的目标功率来计算第一上行传输的发 射功率。
在一种可能的实现中，如果第一功率调整信息中的TPC是一个绝对值，第一终端设备不用将第一功率调整信息中的TPC与第三功率调整信息中的TPC进行叠加。如果第一功率调整信息中的目标功率是一个绝对值，第一终端设备不用将第一功率调整信息中的目标功率与第三功率调整信息或RRC信令中的目标功率进行叠加。
举例来说，如图9所示，网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输，该DCI信令2指示的TPC为12db，目标功率为14db。网络设备在时隙4确定在时隙6要调度终端设备2和终端设备3进行下行传输，此时考虑到终端设备2和终端设备3在时隙6对PUSCH2会产生自干扰，网络设备认为DCI信令2指示的TPC和/或目标功率已不准确。因此，网络设备在时隙4向终端设备1下发DCI信令3，该DCI信令3指示TPC为14db和/或目标功率为17db，以及指示该TPC和/或该目标功率应用的时隙6。终端设备1直接使用14db的TPC和/或17db的目标功率来计算PUSCH2的发射功率。
802、网络设备向第一终端设备发送第一信令，该第一信令包括第一信息和第二信息。相应地，第一终端设备可以接收该第一信令。
本申请实施例中，第一信令不用于调度。可选的，第一信令不包括上行调度信息或下行调度信息。第一信令在第三信令之后传输。
在一种可能的实现中，第一信令为组公共控制指令。关于组公共控制指令和专用控制信令的介绍可参见前文中的描述，在此不赘述。由于组公共控制信令是发给一组终端设备的，而不是用户特定的(UE-specific)，避免了网络设备为终端设备组中的每个终端设备分别生成不同的信令造成信令开销大的问题，降低了网络设备的信令开销。
在一种可能的实现中，第一信令为专用控制指令。关于专用控制信令的介绍可参见前文中的描述，在此不赘述。
例如，如果第一信令为组公共控制指令，第一信令用于一个终端设备组，该终端设备组包括第一终端设备、第二终端设备和第三终端设备，则网络设备将第一信令发送给第一终端设备、第二终端设备和第三终端设备。如果第一信令为专用控制指令，网络设备只向第一终端设备发送第一信令。
在一种可能的实现中，第一信令为组公共控制信令，第二信息包括N个子带的功率调整信息域，第一上行传输位于N个子带中的一个或多个子带，N为大于1的整数。其中，功率调整信息域用于携带第一功率调整信息。基于该可能的实现方式，能够准确地向多个终端设备指示其对应的功率调整信息。
例如，以N为6为例。第二信息包括功率调整信息域1～功率调整信息域3。功率调整信息域1用于携带子带1和子带2上的第一上行传输1的第一功率调整信息1。功率调整信息域2用于携带子带3和子带4上的第一上行传输2的第一功率调整信息2。功率调整信息域3用于携带子带5和子带6上的第一上行传输3的第一功率调整信息3。
假设第一终端设备的第一上行传输位于子带1和子带2，则第一终端设备从功率调整信息域1中读取第一功率调整信息。假设第一终端设备的第一上行传输位于子带3和子带4，则第一终端设备从功率调整信息域2中读取第一功率调整信息。假设第一终端设备的第一上行传输位于子带5和子带6，则第一终端设备从功率调整信息域3中读取第一功率调整信息。
又例如，以N为3为例。第二信息包括功率调整信息域1～功率调整信息域3。功率调整信息域1用于携带子带1上的第一上行传输1的第一功率调整信息1。功率调整信息域2用 于携带子带2上的第一上行传输2的第一功率调整信息2。功率调整信息域3用于携带子带3上的第一上行传输3的第一功率调整信息3。
假设第一终端设备的第一上行传输位于子带1，则第一终端设备从功率调整信息域1中读取第一功率调整信息。假设第一终端设备的第一上行传输位于子带2，则第一终端设备从功率调整信息域2中读取第一功率调整信息。假设第一终端设备的第一上行传输位于子带3，则第一终端设备从功率调整信息域3中读取第一功率调整信息。
下面对第一信息指示第一全双工时间单元的方式进行介绍：
一、显示指示
例如，如果第一信息显示地指示第一全双工时间单元，则第一信息可以直接包括第一全双工时间单元的索引。
二、隐式指示
(1)第一信息包括从T1到T2的时间单元偏移量，该T1为传输携带第一信息和第二信息的第一信令的时间单元，该T2为第一全双工时间单元。也就是说，第一信息通过指示传输第一信令的时间单元至第一全双工时间单元的偏移量，来隐式地指示第一全双工时间单元。通过T1到T2的时间单元偏移量来指示第一全双工时间单元，可以有效指示第一全双工时间单元，使得第一终端设备能获知准确应用第一功率调整信息的时间单元，且通过T1到T2的时间单元偏移量来指示第一全双工时间单元，有助于减少第一信令的开销，可以减少第一信令的比特数，最小化成本。
例如，网络设备在第5个时隙发送第一信令，第一全双工时间单元为第8个时隙，则第一信息包括的偏移量为3个时隙。第一终端设备基于接收第一信令的时隙以及该偏移量就能确定第一全双工时间单元。
(2)第一信令为专用控制信令，该第一信息包括混合自动重传请求(hybrid automatic repeat request，HARQ)进程号，该HARQ进程号对应第一全双工时间单元。也就是说，第一信息通过指示HARQ进程号来指示第一全双工时间单元。通过HARQ进程号来指示第一全双工时间单元，可以在不引入任何新的参考信息的情况下指示第一全双工时间单元。
HARQ进程号对应时间单元，表示HARQ进程号对应的数据传输位于该时间单元。第一终端设备基于有效时段内的HARQ进程，能确定某个HARQ进程号对应的数据传输所在的时间单元。所述有效时段指的是最大个数HARQ进程可以持续的调度时间，通过限制基于有效时段内的HARQ进程来确定某个HARQ进程号对应的上行传输所在的时间单元，可以保证终端设备不会产生混淆，不会出现对多个持有相同HARQ进程号的数据无法准确区分和适用的情形。
例如，假设HARQ进程号1对应时隙1，HARQ进程号2对应时隙2，HARQ进程号3对应时隙3。如果第一信息包括HARQ进程号2，则第一信息指示第一全双工时间单元为时隙2。作为示例，HARQ进程号2对应时隙2，表示HARQ进程号2相应的数据传输位于时隙2。即如果第三信令调度的数据传输位于时隙2，第三信令包括HARQ进程号2，那么HARQ进程号2对应时隙2。这种情况下，如果第一信令中的第一信息包括HARQ进程号2隐含指示时隙2。
在一种可能的实现中，第一信令为在T2-Δt之前传输的信令，T2为第一全双工时间单元，Δt为第一上行传输的功率调整时延。本申请中，功率调整时延也可以理解为处理时延或准备时延。如图9所示，假设第一全双工时间单元为时隙6，第一终端设备发送第一上行传输之前需要调整第一上行传输的发射功率，假设调整第一上行传输的功率调整时延Δt为2个时隙， 则第一信令应该在时隙5之前传输。基于该可能的实现方式，能够保证第一终端设备有足够的时间确定和调整第一上行传输的发射功率。
第一信令具有以下两种下发时机：
一、网络设备确定完第一全双工时间单元内所有用于下行传输的终端设备时，确定第一信息和第二信息，并下发第一信令。网络设备最晚不超过T2-Δt下发第一信令，从而保证第一终端设备有足够的时间确定并调整第一上行传输的发射功率。也就是说，这种方式是网络设备确定完第一全双工时间单元内的所有干扰之后，才下发一个信令调整第一上行传输的发射功率。在这种方式中，网络设备只会下发一个信令来指示第一上行传输的功率调整信息，这样有利于节省指示开销。
本申请中，网络设备最晚不超过T2-Δt下发第一信令，可以理解为网络设备在不超过T2-Δt的对应时隙的前几个符号下发第一信令。
举例来说，以第一功率调整信息为相对于第三功率调整信息的偏移量，第一上行传输的功率调整时延Δt为2个时隙为例。如图9所示，网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输。网络设备发送DCI信令2之后，在时隙3确定终端设备2～终端设备3用于在时隙6进行下行传输。网络设备在时隙4又确定终端设备4～终端设备5用于在时隙6进行下行传输。网络设备在时隙4确定完终端设备2～终端设备5用于在时隙6进行下行传输之后，发送DCI信令3，该DCI信令3指示TPC为4db和/或目标功率为6db，以及指示该TPC和/或该目标功率应用于时隙6。终端设备1将DCI信令3指示的TPC与DCI信令2指示的TPC进行叠加，和/或，终端设备1将DCI信令3指示的目标功率与DCI信令2指示的目标功率进行叠加，并基于叠加之后的TPC和/或叠加之后的目标功率来确定PUSCH2的发射功率。
二、网络设备确定第一全双工时间单元内部分用于下行传输的终端设备时，就确定第一信息和第二信息，并下发第一信令。网络设备还可在下发第一信令之后，向第一终端设备发送第二信令，该第二信令包括第三信息和第四信息，该第三信息指示第一全双工时间单元，该第四信息指示第一上行传输的第二功率调整信息。该第二功率调整信息为相对于第一功率调整信息的偏移量。第一终端设备接收到第一信令和第二信令之后，基于第一信令和第二信令来确定第一上行传输的发射功率。例如，如图10的步骤1003和步骤1004所示。图10中其他步骤的具体实现方式与图8中对应步骤的具体实现方式相同，在此不赘述。
网络设备最晚不超过T2-Δt下发第一信令和第二信令，从而保证第一终端设备有足够的时间确定并调整第一上行传输的发射功率。本申请中，网络设备最晚不超过T2-Δt下发第一信令和第二信令，可以理解为网络设备在不超过T2-Δt的对应时隙的前几个符号下发第一信令和第二信令。
在第二种第一信令的下发时机中，网络设备可以分多次向第一终端设备下发第一上行传输的功率调整信息。如果网络设备确定完第一全双工时间单元内所有用于下行传输的终端设备之后，才向第一终端设备下发第一上行传输的功率调整信息，网络设备可能面临没有充足的下发资源用于功率调整信息的发送，或者不能保证第一终端设备在接收第一上行传输的功率调整信息之后，有足够的时间确定和调整第一上行传输的发射功率。因此，可能造成第一终端设备无法对第一上行传输进行有效的功率弥补，无法缓解第一上行传输在网络设备处遭受的自干扰影响，第一上行传输无法被网络设备正确接收。而如果网络设备分多次向第一终端设备下发第一上行传输的功率调整信息，网络设备在确定有下行传输会对第一上行传输会产生自干扰影响时，就可及时下发第一上行传输的功率调整信息，可以保证有充足的下发资 源用于功率调整信息的发送，保证第一终端设备在接收第一上行传输的功率调整信息之后，有足够的时间确定和调整第一上行传输的发射功率。因此，有利于第一终端设备对第一上行传输进行有效的功率弥补，缓解第一上行传输在网络设备处遭受的自干扰影响，使得第一上行传输被网络设备正确接收。
举例来说，以第一功率调整信息为相对于第三功率调整信息的偏移量，第一上行传输的功率调整时延Δt为2个时隙为例。如图11所示，网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输。网络设备发送DCI信令2之后，在时隙3确定终端设备2～终端设备3用于在时隙6进行下行传输。网络设备在时隙3向终端设备1发送DCI信令3，该DCI信令3指示TPC为2db和/或目标功率为3db，以及指示该TPC和/或该目标功率应用的时隙6。网络设备在时隙4又确定终端设备4～终端设备5用于在时隙6进行下行传输。网络设备在时隙4发送DCI信令4，该DCI信令4指示TPC为2db和/或目标功率为3db，以及指示该TPC和/或该目标功率应用的时隙6。第一终端设备将DCI信令2指示的TPC、DCI信令3指示的TPC与DCI信令4指示的TPC进行叠加，和/或，将DCI信令2指示的目标功率、DCI信令3指示的目标功率与DCI信令4指示的目标功率进行叠加，并基于叠加之后的TPC和/或叠加之后的目标功率来确定PUSCH2的发射功率。
再举例来说，以第一功率调整信息为绝对值，第一上行传输的功率调整时延Δt为2个时隙为例。如图11所示，网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输。网络设备发送DCI信令2之后，在时隙3确定终端设备2～终端设备3用于在时隙6进行下行传输。网络设备在时隙3向终端设备1发送DCI信令3，该DCI信令3指示TPC为10db和/或目标功率为10db，以及指示该TPC和/或该目标功率应用的时隙6。网络设备在时隙4又确定终端设备4～终端设备5用于在时隙6进行下行传输。网络设备在时隙4发送DCI信令4，该DCI信令4指示TPC为2db和/或目标功率为3db以及指示该TPC和/或该目标功率应用的时隙6。第一终端设备将DCI信令3指示的TPC与DCI信令4指示的TPC进行叠加，得到叠加后的TPC为12db，和/或，第一终端设备将DCI信令3指示的目标功率与DCI信令4指示的目标功率进行叠加，得到叠加后的目标功率为13db。第一终端设备并基于叠加之后的TPC和/或叠加之后的目标功率来确定PUSCH2的发射功率。
网络设备可预先在第一终端设备配置两套功率调整信息。网络设备确定采用第一种第一信令下发时机时，使用第一套功率调整信息。网络设备确定采用第二种第一信令下发时机时，使用第二套功率调整信息。第一套功率调整信息对应的功率调整信息范围大于第二套功率调整信息对应的功率调整信息范围。网络设备可通过信令指示第一终端设备使用哪一套功率调整信息。例如，该信令可以为RRC信令。
以功率调整信息为TPC为例。作为一个示例，网络设备配置的第一套功率调整信息如下表1所示。其中，网络设备除配置TPC之外，还可配置TPC对应的索引(index)。网络设备可通过指示索引来指示对应的TPC的值。本申请中，索引也可以理解为序列号。

在网络设备确定采用上述第一种第一信令的下发时机的情况下，网络设备确定使用第一套功率调整信息。如图9所示，当网络设备在时隙4确定终端设备2～终端设备5用于在时隙6(第一全双工时间)进行下行传输时，网络设备确定终端设备2～终端设备5对终端设备1产生干扰影响，网络设备确定终端设备1需要提升的功率值，以用于弥补终端设备2～终端设备5对终端设备1产生的自干扰带来的信噪比下降。当该需要提升的功率值大于或等于第一套功率调整信息中最小的TPC时，网络设备确定第一功率调整信息。或者，当该需要提升的 功率值大于或等于第一套功率调整范围值中至少一个TPC时，网络设备确定第一功率调整信息。作为示例，如表1所示，当需要提升的功率值大于或等于9，且小于12时，网络设备确定第一功率调整信息为9db。网络设备生成第一信息和第二信息，该第一信息指示时隙6，该第二信息可以是第一套功率调整信息表格中的索引3，用于指示第一功率调整信息为9db。网络设备向终端设备1发送包括第一信息和第二信息的第一信令(即图9的DCI信令3)。
在网络设备确定采用上述第二种第一信令的下发时机的情况下，网络设备确定使用第二套功率调整信息。如图11所示，当网络设备在时隙3确定终端设备2～终端设备3用于在时隙6(第一全双工时间)进行下行传输时，网络设备确定终端设备2～终端设备3对终端设备1产生干扰影响，网络设备确定终端设备1需要提升的功率值，以用于弥补终端设备2～终端设备3对终端设备1产生的自干扰带来的信噪比下降。当该需要提升的功率值大于或等于第二套功率调整信息中最小的TPC时，网络设备确定第一功率调整信息。或者，当该需要提升的功率值大于或等于第二套功率调整范围值中至少一个TPC时，网络设备确定第一功率调整信息。作为示例，如表3所示，当需要提升的功率值大于或等于3，且小于5时，网络设备确定第一功率调整信息为3db。网络设备生成第一信息和第二信息，该第一信息指示时隙6，该第二信息可以是第二套功率调整信息表格中的索引2，用于指示第一功率调整信息为3db。网络设备向终端设备1发送包括第一信息和第二信息的第一信令(即图11的DCI信令3)。
本申请中，包括第一信息和第二信息的第一信令，可以理解为只包含第一信息和第二信息的第一信令。以此类推，网络设备在时隙4又确定终端设备4～终端设备5用于在时隙6进行下行传输。当网络设备在时隙4确定第一终端设备2～终端设备3用于在时隙6(第一全双工时间)进行下行传输时，网络设备确定终端设备2～终端设备3对终端设备1产生干扰影响，网络设备确定终端设备1需要提升的功率值以用于弥补终端设备2～终端设备3对终端设备1产生的自干扰带来的信噪比的下降。当该需要提升的功率值大于或等于第二套功率调整范围值中最小的TPC时，网络设备相应确定第二功率调整信息。或者，当该需要提升的功率值大于或等于第二套功率调整范围值中至少一个TPC时，网络设备相应确定第二功率调整信息。作为示例，当需要提升的功率值大于或等于5，且小于6时，网络设备确定第二功率调整信息为5db。网络设备生成第三信息和第四信息，该第三信息指示时隙6，该第四信息可以是第二套功率调整信息表格中的索引3，用于指示第二功率调整信息为5db。网络设备向终端设备1发送包括第三信息和第四信息的第二信令(即图11的DCI信令4)。
803、第一终端设备根据第一信令，确定第一上行传输的发射功率。
本申请实施例中，第一终端设备接收第一信令之后，根据第一信令，确定第一上行传输的发射功率。第一终端设备如何根据第一信令，确定第一上行传输的发射功率可参见前文中的描述，在此不赘述。
可见，基于图8所描述的方法，网络设备能够在确定第一全双工时间单元内用于下行传输的终端设备之后，及时地向第一终端设备下发信令来调整第一终端设备在第一全双工时间单元内的第一上行传输的发射功率，有利于避免第一上行传输受到强烈的自干扰，避免降低全双工的增益。
图12是本申请实施例提供的另一种功率确定方法的流程示意图。如图12所示，该功率确定方法包括如下步骤1201～步骤1206。图12所示的方法执行主体可以为第一终端设备和网络设备。或者，图12所示的方法执行主体可以为第一终端设备中的芯片和网络设备中的芯片。图12以第一终端设备和网络设备为方法的执行主体为例进行说明。
1201、网络设备向第一终端设备发送第三信令。
其中，第三信令包括第一上行传输的调度信息，第一上行传输的调度信息指示第一上行传输的第三功率调整信息；或者，第三信令包括第一下行传输的调度信息，第一上行传输用于传输第一下行传输的反馈信息，第一下行传输的调度信息指示第一上行传输的第三功率调整信息。关于第三信令的描述，可参见图8所对应的方法实施例中的描述，在此不赘述。
1202、网络设备确定第一信息和第二信息。
其中，该第一信息指示第一全双工时间单元，该第二信息指示第一上行传输的第一功率调整信息，该第一上行传输为位于第一全双工时间单元的上行传输。
1203、网络设备向第一终端设备发送第一信令，该第一信令包括第一信息和第二信息。相应地，第一终端设备可以接收该第一信令。
1204、第一终端设备根据第一信令和第三信令，确定第一上行传输的发射功率。
步骤1202～步骤1204的具体实现方式可参见图8所对应的实施例中的描述，在此不赘述。
1205、网络设备向第一终端设备发送第四信令。相应地，第一终端设备可以接收该第四信令。
其中，该第四信令包括第二上行传输的调度信息，或者，该第四信令包括第二下行传输的调度信息，第二上行传输用于传输第二下行传输的反馈信息。第二上行传输在时域上位于第一上行传输之后。第四信令中的调度信息指示第四功率调整信息。
1206、第一终端设备根据第三信令和第四信令，确定第二上行传输的发射功率。
本申请实施例中，第一信令不用于来确定第二上行传输的发射功率。即第一信令只对第一全双工时间单元中的上行传输生效，对第一全双工时间单元之后的上行传输无效。
举例来说，以第三信令和第四信令指示的功率调整信息为偏移量为例。如图13所示，网络设备在时隙1向终端设备1下发了DCI信令1，该DCI信令1用于调度PUSCH1在时隙5传输。该DCI信令1指示的TPC为10db。该DCI信令1指示的目标功率为10db。
网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙6传输。该DCI信令2指示的TPC为2db，该DCI信令2指示的TPC为相较于DCI信令1指示的TPC的偏移量。该DCI信令2指示的目标功率为11db。
网络设备在时隙3向终端设备1下发了DCI信令3，该DCI信令3用于调度PUSCH3在时隙7传输。该DCI信令3指示的TPC为2db，该DCI信令3指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令3指示的目标功率为12db。
网络设备在时隙4确定在时隙6要调度终端设备2和终端设备3进行下行传输，此时考虑到终端设备2和终端设备3在时隙6对PUSCH2会产生自干扰，网络设备认为DCI信令2指示的TPC已不准确。因此，网络设备在时隙4向终端设备1下发DCI信令4，该DCI信令4指示3db的TPC和/或3db的目标功率，以及指示该TPC和/或目标功率应用的时隙6。该DCI信令4指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令4指示的目标功率为相较于DCI信令2指示的目标功率的偏移量。
终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC以及DCI信令4指示的TPC进行累计，得到累计后的TPC为15db，和/或，终端设备1将DCI信令2指示的目标功率以及DCI信令4指示的目标功率进行累计，得到累计后的目标功率为14db。终端设备1使用15db的TPC和/或14db的目标功率来计算PUSCH2的发射功率。
终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC以及DCI信令3指示的TPC进行累计，得到累计后的TPC为14db。终端设备1使用14db的TPC和12db的目标功 率来计算PUSCH3的发射功率。终端设备1不会将DCI信令3指示的TPC与DCI信令4指示的TPC进行累计。
可见，基于图12所描述的方法，可以避免在对第一全双工时间单元内的第一上行传输的发射功率进行调整之后，影响第一上行传输之后的上行传输的发射功率。因此，基于图12所描述的方法，可以有针对性的对某个全双工时间单元内的上行传输的发射功率进行调整。
图14是本申请实施例提供的另一种功率确定方法的流程示意图。如图14所示，该功率确定方法包括如下步骤1401～步骤1405。图14所示的方法执行主体可以为第一终端设备、第二终端设备和网络设备。或者，图14所示的方法执行主体可以为第一终端设备中的芯片、第二终端设备中的芯片和网络设备中的芯片。图14以第一终端设备、第二终端设备和网络设备为方法的执行主体为例进行说明。
1401、网络设备确定第一信息和第二信息。
其中，该第一信息指示第一全双工时间单元，该第二信息指示第一上行传输的第一功率调整信息，该第一上行传输为位于第一全双工时间单元的上行传输。
1402、网络设备向第一终端设备和第二终端设备发送第一信令，该第一信令包括第一信息和第二信息。相应地，第一终端设备和第二终端设备可以接收该第一信令。
本申请实施例中，第一信令为组公共控制指令。第一终端设备和第二终端设备属于一个终端设备组。或者，第一终端设备和第二终端设备都被配置了用于解析第一信令的RNTI。所以，第一终端设备和第二终端设备都可以接收到第一信令。
1403、第一终端设备根据第一信令，确定第一上行传输的发射功率。
步骤1401～步骤1403的具体实现方式可参见图8所对应的实施例中的描述，在此不赘述。
1404、网络设备向第二终端设备发送第五信令。相应地，第二终端设备可以接收该第五信令。
其中，该第五信令包括第三上行传输的调度信息，或，第五信令包括第三下行传输的调度信息，第三上行传输用于传输第三下行传输的反馈信息。第三上行传输位于第二时间单元，第二时间单元不同于第一全双工时间单元。第五信令可以是在第一全双工时间单元之前传输的。
可选的，第二时间单元是全双工时间单元或者非全双工时间单元。本申请实施例全文中，非全双工时间单元可以理解为未被配置全双工的时间单元。
1405、第二终端设备确定第三上行传输的发射功率。其中，第一信令不用于确定第三上行传输的发射功率。
可选的，第二终端设备可基于第五信令确定第三上行传输的发射功率。或者，第二终端设备可基于除第一信令之外的其他信令来确定第三上行传输的发射功率。
可选的，当第二时间单元不同于第一全双工时间单元时，第二终端设备确定第一信令不用于确定第三上行传输的发射功率。也就是说，第二终端设备接收第五信令之后，会判断第三上行传输是否处于第一全双工时间单元，如果不是，则不采用第一信令来确定第三上行传输的发射功率。可选的，第二终端设备可以丢弃该第一信令。
举例来说，如图15所示，网络设备在时隙2向终端设备2发送DCI信令1，DCI信令1用于调度PUSCH1在时隙6传输，并指示TPC和目标功率。网络设备在时隙3向终端设备1和终端设备2发送DCI信令2，该DCI信令2中指示TPC和/或目标功率以及该TPC和/或目标功率应用的时隙5。终端设备2接收DCI信令1和DCI信令2之后，确定PUSCH1所在时 隙与DCI信令2指示的时隙不相同，终端设备2确定不使用DCI信令2指示的TPC来确定PUSCH1的发射功率。终端设备2可使用DCI信令1指示的TPC和目标功率来确定PUSCH1的发射功率。
可见，基于图14所描述的方法，终端设备在接收到组播的第一信令之后，如果终端设备中的第二上行传输不在第一信令指示的全双工时间单元内，则不使用该第一信令来确定该第二上行传输的发射功率，这样终端设备可以准确地确定第二上行传输的发射功率。
图16是本申请实施例提供的另一种功率确定方法的流程示意图。如图16所示，该功率确定方法包括如下步骤1601～步骤1603。图16所示的方法执行主体可以为终端设备和网络设备。或者，图16所示的方法执行主体可以为终端设备中的芯片和网络设备中的芯片。图16以终端设备和网络设备为方法的执行主体为例进行说明。
1601、网络设备确定第一信息。
其中，该第一信息指示第一上行传输的第一功率调整信息，该第一上行传输为位于第一全双工时间单元的上行传输。关于全双工时间单元的描述可参见前文专业术语的相关描述，在此不赘述。
本申请中，功率调整信息也可以理解为功率确定信息，功率控制信息或者功率弥补信息。
在一种可能的实现中，第一上行传输可以为上行信号的传输或物理上行信道的传输或物理上行信道上所承载的传输。例如，上行信号的传输包括SRS的传输。物理上行信道的传输包括PUSCH的传输或PUCCH的传输。物理上行信道上所承载的传输包括PUSCH上所承载的传输、PUCCH上所承载的传输或PUSCH上所承载的UCI的传输。
本申请实施例中，网络设备还可在确定第一信息之前，向第一终端设备发送第三信令。相应地，第一终端设备可以接收该第三信令。该第三信令可以为DCI信令。其中，该第三信令包括第一上行传输的调度信息，第一上行传输的调度信息包括第一上行传输的第三功率调整信息；或者，该第三信令包括第一下行传输的调度信息，第一上行传输用于传输第一下行传输的反馈信息，第一下行传输的调度信息包括第一上行传输的第三功率调整信息。
如果该第三信令包括第一上行传输的调度信息，即第三信令用于调度第一上行传输。作为示例，第一上行传输包括SRS的传输、PUSCH的传输或PUSCH上所承载的传输。如果该第三信令包括第一下行传输的调度信息，即第三信令用于调度第一下行传输。作为示例，第一下行传输包括PDSCH的传输或PDSCH上所承载的传输。这种情况下，第一上行传输为PUCCH或PUCCH上所承载的传输。或者，第一上行传输为PUSCH上所承载的UCI的传输。
在另一种可能的实现中，网络设备也可以不发送第三信令，网络设备可在确定第一信息之前，向第一终端设备发送非授权(grant free)调度信令。该非授权调度信令包括第一上行传输的调度信息。相应地，第一终端设备可以接收该非授权调度信令。其中，非授权调度信令可以为RRC信令，或者通过DCI触发的RRC信令。通过DCI触发的RRC信令也可以理解为RRC信令结合DCI信令。RRC信令非授权调度可以为type I的非授权调度。RRC信令结合DCI信令的非授权调度可以为type II的非授权调度。作为示例，第一上行传输包括SRS的传输、PUSCH的传输、PUSCH上所承载的传输、PUCCH的传输、PUCCH上所承载的传输或PUSCH上所承载的UCI的传输。
如果网络设备向第一终端设备发送非授权调度信令，网络设备还可向第一终端设备发送一个DCI信令，该DCI信令携带第一上行传输的第三功率调整信息。相应地，第一终端设备可以接收该DCI信令。
在一种可能的实现中，第三功率调整信息包括第一上行传输的TPC和/或第一上行传输的目标功率。或者，第三功率调整信息还可以是其他用于确定第一上行传输的发射功率的参数。第三功率调整信息中的TPC可以是绝对值或者是偏移量。基于前文中对闭环功率控制的描述可知，如果是绝对式功率控制，第三功率调整信息中的TPC是绝对值。如果是累积式功率控制，则第三功率调整信息中的TPC是偏移量。例如，第三功率调整信息中的TPC是相对于上一个用于调度上行或下行传输的信令指示的TPC的偏移量。
在一种可能的实现中，第一功率调整信息包括第一上行传输的TPC和/或第一上行传输的目标功率。或者，第一功率调整信息还可以是其他用于确定第一上行传输的发射功率的参数。第一功率调整信息中的TPC或目标功率可以是绝对值或者是偏移量。如果第一功率调整信息中的TPC或目标功率是偏移量有利于减少第一信令的开销，可以减少第一信令的比特数，最小化成本。
可选的，如果第一功率调整信息中的TPC是一个偏移量，第一功率调整信息中的TPC可以是相对于第三功率调整信息中的TPC的偏移量。
可选的，如果第一功率调整信息中的目标功率是一个偏移量，第一功率调整信息中的目标功率可以是相对于第三功率调整信息中的目标功率的偏移量。
可选的，如果RRC信令只配置了一个目标功率值，如果第一功率调整信息中的目标功率是一个偏移量，第一功率调整信息中的目标功率可以是相对于RRC信令指示的目标功率的偏移量。
在一种可能的实现中，终端设备可以基于第一信令和第三信令来确定第一上行传输的发射功率。
例如，如果第一功率调整信息中的TPC是相对于第三功率调整信息中的TPC的偏移量。终端设备可以将第一功率调整信息中的TPC和第三功率调整信息中的TPC进行叠加，并基于叠加之后的TPC来计算第一上行传输的发射功率。同理，如果第一功率调整信息中的目标功率是相对于第三功率调整信息中的目标功率的偏移量。终端设备可以将第一功率调整信息中的目标功率和第三功率调整信息中的目标功率进行叠加，并基于叠加之后的目标功率来计算第一上行传输的发射功率。具体示例可参见图8所对应的实施例相应的示例，在此不赘述。
在一种可能的实现中，如果第一功率调整信息中的目标功率是相对于RRC信令指示的目标功率的偏移量。终端设备可以将第一功率调整信息中的目标功率和RRC信令指示的目标功率进行叠加，并基于叠加之后的目标功率来计算第一上行传输的发射功率。具体示例可参见图8所对应的实施例相应的示例，在此不赘述。
在一种可能的实现中，如果第一功率调整信息中的TPC是一个绝对值，终端设备不用将第一功率调整信息中的TPC与第三功率调整信息中的TPC进行叠加。如果第一功率调整信息中的目标功率是一个绝对值，终端设备不用将第一功率调整信息中的目标功率与第三功率调整信息或RRC信令中的目标功率进行叠加。具体示例可参见图8所对应的实施例相应的示例，在此不赘述。
1602、网络设备向终端设备发送第一信令。相应地，终端设备可以接收该第一信令。
其中，该第一信令为专用控制指令，该第一信令包括第一信息。第一信令不用于调度。可选的，第一信令不包括上行调度信息或下行调度信息。
在一种可能的实现中，第一信令为在T2-Δt之前传输的信令，T2为第一全双工时间单元，Δt为第一上行传输的功率调整时延。例如，假设第一全双工时间单元为时隙6，终端设备发送第一上行传输之前需要调整第一上行传输的发射功率，假设调整第一上行传输的功率调整 时延Δt为2个时隙，则第一信令应该在时隙4之前传输。基于该可能的实现方式，能够保证终端设备有足够的时间确定和调整第一上行传输的发射功率。
由于第一信令没有直接指示第一全双工时间单元。如果第一信令为终端设备在T2-Δt之前接收的，终端设备认为第一信令可用于确定第一全双工时间单元中的第一上行传输的发射功率。
第一信令具有以下两种下发时机：
一、网络设备确定完第一全双工时间单元内所有用于下行传输的终端设备时，确定第一信息，并下发第一信令。网络设备最晚不超过T2-Δt下发第一信令，从而保证有足够的时间确定并调整第一上行传输的发射功率。也就是说，这种方式是网络设备确定完第一全双工时间单元内的所有干扰之后，才下发一个信令调整第一上行传输的发射功率。在这种方式中，网络设备只会下发一个信令来指示第一上行传输的功率调整信息。
本申请中，网络设备最晚不超过T2-Δt下发第一信令，可以理解为网络设备在不超过T2-Δt的对应时隙的前几个符号下发第一信令。
二、网络设备确定第一全双工时间单元内部分用于下行传输的终端设备时，就确定第一信息，并下发第一信令。网络设备还可在下发第一信令之后，向发送第二信令，该第二信令不包括上行调度信息或下行调度信息，该第二信令包括第二信息，该第二信息指示第一上行传输的第二功率调整信息。该第二功率调整信息为相对于第一功率调整信息的偏移量。接收到第一信令和第二信令之后，基于第一信令和第二信令来确定第一上行传输的发射功率。例如，如图17的步骤1703和步骤1704所示。图17中其他步骤的具体实现方式与图16中对应步骤的具体实现方式相同，在此不赘述。方式二的具体实现原理与图8所对应的实施例中第一信令的第二种下发时机的实现原理相同，在此不赘述。
网络设备最晚不超过T2-Δt下发第一信令和第二信令，从而保证第一终端设备有足够的时间确定并调整第一上行传输的发射功率。本申请中，网络设备最晚不超过T2-Δt下发第一信令和第二信令，可以理解为网络设备在不超过T2-Δt的对应时隙的前几个符号下发第一信令和第二信令。
由于第一信令和第二信令均没有直接指示第一全双工时间单元。如果第一信令和第二信令为终端设备在T2-Δt之前接收的，终端设备认为第一信令和第二信令可用于确定第一全双工时间单元中的第一上行传输的发射功率。
网络设备可预先在第一终端设备配置两套功率调整信息。网络设备确定采用第一种第一信令下发时机时，使用第一套功率调整信息。网络设备确定采用第二种第一信令下发时机时，使用第二套功率调整信息。第一套功率调整信息对应的功率调整信息范围大于第二套功率调整信息对应的功率调整信息范围。网络设备可通过信令指示第一终端设备使用哪一套功率调整信息。例如，该信令可以为RRC信令。第一套功率调整信息和第二套功率调整信息的相关示例可参见图8所对应的实施例中的相关描述，在此不赘述。
1603、终端设备根据第一信令，确定第一上行传输的发射功率。
可见，基于图16所描述的方法，网络设备能够在确定第一全双工时间单元内用于下行传输的终端设备之后，及时地向第一终端设备下发信令来调整第一终端设备在第一全双工时间单元内的第一上行传输的发射功率，有利于避免第一上行传输受到强烈的自干扰，避免降低全双工的增益。并且，网络设备不用向终端设备指示第一全双工时间单元，这样有利于减少指示开销。
图18是本申请实施例提供的另一种功率确定方法的流程示意图。如图18所示，该功率确定方法包括如下步骤1801～步骤1806。图18所示的方法执行主体可以为终端设备和网络设备。或者，图18所示的方法执行主体可以为终端设备中的芯片和网络设备中的芯片。图18以终端设备和网络设备为方法的执行主体为例进行说明。
1801、网络设备向终端设备发送第三信令。相应地，终端设备可以接收该第三信令。
其中，该第三信令包括第一上行传输的调度信息，第一上行传输的调度信息指示第一上行传输的第三功率调整信息；或者，第三信令包括第一下行传输的调度信息，第一上行传输用于传输第一下行传输的反馈信息，第一下行传输的调度信息指示第一上行传输的第三功率调整信息。
1802、网络设备确定第一信息。
其中，第一信息指示第一上行传输的第一功率调整信息，第一上行传输为位于第一全双工时间单元的上行传输。
1803、网络设备向终端设备发送第一信令。相应地，终端设备可以接收该第一信令。
其中，第一信令为专用控制指令，第一信令包括第一信息。
1804、终端设备根据第一信令和第三信令，确定第一上行传输的发射功率。
其中，步骤1801～步骤1804可参见图16所对应的实施例中的描述，在此不赘述。
1805、网络设备向终端设备发送第四信令。相应地，终端设备可以接收第四信令。
其中，该第四信令包括第二上行传输的调度信息，第二上行传输的调度信息指示第四功率调整信息，或者，第三信令包括第二下行传输的调度信息，第二上行传输用于传输第二下行传输的反馈信息，第二下行传输的调度信息指示第四功率调整信息；第二上行传输在时域上位于第一上行传输之后。
1806、根据第一信令、第三信令和第四信令，确定第二上行传输的发射功率。
本申请实施例中，第二上行传输可位于第二全双工时间单元，或者，第二上行传输也可位于非全双工时间单元。第二上行传输为在时域上位于第一上行传输之后的第一个上行传输，或者，第二上行传输为在时域上位于第一上行传输之后的第X个上行传输，X大于1。
举例来说，以第二上行传输位于非全双工时间单元为例。假设第一上行传输的功率调整时延Δt为3个时隙。如图19所示，网络设备在时隙1向终端设备1下发了DCI信令1，该DCI信令1用于调度PUSCH1在时隙6传输。该DCI信令1指示的TPC为10db，目标功率为10db。
网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙7传输，该DCI信令2指示的TPC为2db，该DCI信令2指示的TPC为相较于DCI信令1指示的TPC的偏移量。该DCI信令2指示的目标功率为11db。
网络设备在时隙3向终端设备1下发了DCI信令3，该DCI信令3用于调度PUSCH3在时隙8传输，该DCI信令3指示的TPC为2db，该DCI信令3指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令3指示的目标功率为12db。
网络设备在时隙4确定在时隙7要调度终端设备2和终端设备3进行下行传输，此时考虑到终端设备2和终端设备3在时隙7对PUSCH2会产生自干扰，网络设备认为DCI信令2指示的TPC和/或目标功率已不准确。因此，网络设备在时隙4向终端设备1下发DCI信令4，该DCI信令4指示3db的TPC和/或3db的目标功率。该DCI信令4指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令4指示的目标功率为相较于DCI信令2指示的目标功率的偏移量。
终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC以及DCI信令4指示的TPC进行累计，得到累计后的TPC为15db，和/或，终端设备1将DCI信令2指示的目标功率以及DCI信令4指示的目标功率进行累计，得到累计后的目标功率为14db。终端设备1使用15db的TPC和/或14db的目标功率来计算PUSCH2的发射功率。
终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC、DCI信令3指示的TPC、DCI信令4指示的TPC进行累计，得到累计后的TPC为17db。终端设备1使用17db的TPC和12db的目标功率来计算PUSCH3的发射功率。
如果第二上行传输位于第二全双工时间单元，则网络设备还可向终端设备发送第五信令，该第五信令包括第三信息，该第三信息指示第二上行传输的第四功率调整信息。网络设备具体根据第一信令、第三信令、第四信令和第五信令，确定第二上行传输的发射功率。
举例来说，以第二上行传输位于第二全双工时间单元为例。假设第一上行传输的功率调整时延Δt为3个时隙。如图20所示，网络设备在时隙1向终端设备1下发了DCI信令1，该DCI信令1用于调度PUSCH1在时隙6传输，该DCI信令1指示的TPC为10db，目标功率为10db。
网络设备在时隙2向终端设备1下发了DCI信令2，该DCI信令2用于调度PUSCH2在时隙7传输，该DCI信令2指示的TPC为2db，该DCI信令2指示的TPC为相较于DCI信令1指示的TPC的偏移量。该DCI信令2指示的目标功率为11db。
网络设备在时隙3向终端设备1下发了DCI信令3，该DCI信令3用于调度PUSCH3在时隙8传输，该DCI信令3指示的TPC为2db，该DCI信令3指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令2指示的目标功率为12db。
网络设备在时隙4确定在时隙7要调度终端设备2和终端设备3进行下行传输，此时考虑到终端设备2和终端设备3在时隙7对PUSCH2会产生自干扰，网络设备认为DCI信令2指示的TPC和/或目标功率已不准确。因此，网络设备在时隙4向终端设备1下发DCI信令4，该DCI信令4指示3db的TPC和/或3db的目标功率。该DCI信令4指示的TPC为相较于DCI信令2指示的TPC的偏移量。该DCI信令4指示的目标功率为相较于DCI信令2指示的目标功率的偏移量。
网络设备在时隙5确定在时隙8要调度终端设备4和终端设备5进行下行传输，此时考虑到终端设备4和终端设备5在时隙8对PUSCH3会产生自干扰，网络设备认为DCI信令3指示的TPC和/或目标功率已不准确。因此，网络设备在时隙5向终端设备1下发DCI信令5，该DCI信令5指示3db的TPC和/或3db的目标功率。该DCI信令5指示的TPC为相较于DCI信令3指示的TPC和DCI信令4指示的TPC之和的偏移量。该DCI信令5指示的目标功率为相较于DCI信令3指示的目标功率和DCI信令4指示的目标功率之和的偏移量。
终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC以及DCI信令4指示的TPC进行累计，得到累计后的TPC为15db，和/或，终端设备1将DCI信令2指示的目标功率以及DCI信令4指示的目标功率进行累计，得到累计后的TPC为14db。终端设备1使用15db的TPC和/或14db的目标功率来计算PUSCH2的发射功率。
终端设备1将DCI信令1指示的TPC、DCI信令2指示的TPC、DCI信令3指示的TPC、DCI信令4指示的TPC和DCI信令5指示的TPC进行累计，得到累计后的TPC为20db。和/或，终端设备1将DCI信令3指示的目标功率、DCI信令4指示的目标功率、DCI信令5指示的目标功率进行累计，得到累计后的TPC为18db。终端设备1使用20db的TPC和/或18db的目标功率来计算PUSCH3的发射功率。
可见，对于时隙7中的PUSCH2，终端设备需要使用到DCI信令4指示的TPC和/或目标功率确定PUSCH2的发射功率。对于时隙8中的PUSCH3，终端设备需要使用到DCI信令4和DCI信令5指示的TPC和/或目标功率确定PUSCH3的发射功率。也就是说，基于图18所描述的方案，对于第二全双工时间单元，终端设备可以认为在第二全双工时间单元的T3-Δt2之前检测到的DCI信令都可用于确定第二全双工时间单元内上行传输的发射功率，该DCI信令为不包括调度信息的DCI信令。T3为第二全双工时间单元，Δt2为第二上行传输的功率调整时延。
基于图18所描述的方法，即使网络设备发送的信令中并没有明确的信息来指示其应该应用于哪个全双工时间单元，终端设备也能准确地确定该全双工时间单元内的上行传输的发射功率。
图21是本申请实施例提供的另一种功率确定方法的流程示意图。如图21所示，该功率确定方法包括如下步骤2101～步骤2102。图21所示的方法执行主体可以为终端设备和网络设备。或者，图21所示的方法执行主体可以为终端设备中的芯片和网络设备中的芯片。图21以终端设备和网络设备为方法的执行主体为例进行说明。
2101、网络设备向终端设备发送第一信息，该第一信息指示随机接入的至少两个功率爬坡值。相应地，终端设备可以接收该第一信息。
2102、终端设备根据第一时间单元的类型和第二时间单元的类型，从该至少两个功率爬坡值中确定在第二时间单元进行随机接入使用的功率爬坡值，该类型为全双工或非全双工。该类型还可以是其他的类型，本申请实施例不做限定。
其中，第一时间单元和第二时间单元为相邻两个随机接入时机。第一时间单元和第二时间单元具体为网络设备配置给同一个终端设备的相邻两个随机接入时机。所述相邻两个随机接入时机在时间域上可以是非连续的。所述相邻两个随机接入时机为在网络设备配置给终端设备的随机接入时机中所确定出来的。
其中，第一时间单元位于第二时间单元之前。
在一种可能的实现中，第一时间单元为上一个随机接入时机，第二时间单元为当前的随机接入时机；或者，第一时间单元为当前的随机接入时机，第二时间单元为下一个随机接入时机。
在一种可能的实现中，第一信息指示的至少两个功率爬坡值包括第一功率爬坡值和第二功率爬坡值，第一功率爬坡值小于第二功率爬坡值；
当第一时间单元的类型为非全双工，且第二时间单元的类型为全双工时，在第二时间单元随机接入使用的功率爬坡值为第二功率爬坡值；或者，
当第一时间单元的类型为非全双工，且第二时间单元的类型为非全双工时，在第二时间单元随机接入使用的功率爬坡值为第一功率爬坡值；或者，
当第一时间单元的类型为全双工，且第二时间单元的类型为非全双工时，在第二时间单元随机接入使用的功率爬坡值为第一功率爬坡值；或者，
当第一时间单元的类型为全双工，且第二时间单元的类型为全双工时，在第二时间单元随机接入使用的功率爬坡值为第一功率爬坡值。
由于全双工时间单元内的干扰较大，因此，从非全双工时间单元切换到全双工时间单元时，需要更大的发射功率进行随机接入。
举例来说，如图22所示，如果第一时间单元为时隙1，第二时间单元为时隙3，则在第 二时间单元随机接入使用的功率爬坡值为第一功率爬坡值。如果第一时间单元为时隙3，第二时间单元为时隙5，则在第二时间单元随机接入使用的功率爬坡值为第二功率爬坡值。如果第一时间单元为时隙5，第二时间单元为时隙7，则在第二时间单元随机接入使用的功率爬坡值为第一功率爬坡值。如果第一时间单元为时隙7，第二时间单元为时隙9，则在第二时间单元随机接入使用的功率爬坡值为第一功率爬坡值。
可选的，第一信息指示的至少两个功率爬坡值包括第一功率爬坡值、第二功率爬坡值和第三功率爬坡值，第一功率爬坡值小于第二功率爬坡值，第三功率爬坡值也小于第二功率爬坡值；当第一时间单元的类型为全双工，且第二时间单元的类型为全双工时，在第二时间单元随机接入使用的功率爬坡值为第三功率爬坡值。例如，如图23所示。
第一信息可以显式地指示第二功率爬坡值，例如，第一信息可以直接包括第一功率爬坡值和第二功率爬坡值。或者，第一信息可以隐式地指示第二功率爬坡值，第一信息包括第一功率爬坡值和第二功率爬坡值相对于第一功率爬坡值的偏移量。
基于图21所描述的方法，终端设备能够准确地确定进行随机接入使用的功率爬坡值，从而提升随机接入的成功率。
