下面对本申请的应用场景进行介绍,请参见图1,图1是本发明实施例提供的一种系统的架构图。具体的,如图1所示,该系统中可包括第一网络设备101、第二网络设备102和通信设备103。
在NR CA中,通信设备103可以和第一网络设备101建立连接,第二网络设备102可以向第一网络设备101提供无线资源,以实现CA。以CA中存在两个CC为例,CC1的时 隙长度与CC2的时隙长度不相同,当通信设备103确定使用CC1的第一时隙上报功率余量时,通信设备103可以基于第一时隙计算CC1的功率余量,并确定CC2中用于计算功率余量的第二时隙,基于第二时隙计算CC2的功率余量,使用第一时隙向第一网络设备101上报CC1的功率余量和CC2的功率余量。
在双连接(Dual Connectivity,DC)中,该第一网络设备101和第二网络设备102可采用双连接模式与该通信设备103通信,即通信设备103可以同时工作在该第一网络设备101所在的系统(即第一系统)和该第二网络设备102所在的系统(即第二系统)中。可选的,该第一系统和第二系统中所使用的无线接入技术可以相同也可以不同,即该第一网络设备101和第二网络设备102的网络设备的类型可以相同,也可以不同。例如,以网络设备为基站为例,第一系统和第二系统可以分别使用LTE技术和5G NR技术,即该第一基站和第二基站可以分别为LTE基站eNB和5G基站gNB;或者,第一系统和第二系统均使用5G技术,即该第一基站和第二基站可以均为gNB,等等,此处不一一列举。进一步可选的,5G系统后续演进还考虑多连接的部署,通信设备103还可与多个(大于2个)网络设备例如基站建立连接,该多个基站可采用多连接模式与一个通信设备103进行通信。以DC为例,针对任一系统,通信设备103可以进行CA操作,例如关于第一系统的CA中存在两个CC为例,CC3的时隙长度与CC4的时隙长度不相同,当通信设备103确定使用CC3的第一时隙上报功率余量时,通信设备103可以基于第一时隙计算CC3的功率余量,并确定CC4中用于计算功率余量的第二时隙,基于第二时隙计算CC4的功率余量,使用第一时隙向第一网络设备101上报CC3的功率余量和CC4的功率余量。又如关于第二系统的CA中存在两个CC为例,CC5的时隙长度与CC6的时隙长度不相同,当通信设备103确定使用CC5的第一时隙上报功率余量时,通信设备103可以基于第一时隙计算CC5的功率余量,并确定CC6中用于计算功率余量的第二时隙,基于第二时隙计算CC6的功率余量,使用第一时隙向第二网络设备102上报CC5的功率余量和CC6的功率余量。
可选的,该第一网络设备101和第二网络设备102可以是共站部署的,即该第一网络设备101和第二网络设备102可以部署于一个网络设备中;或者,该第一网络设备101和第二网络设备102可以是异站部署的,即该第一网络设备101和第二网络设备102可以独立部署。第一网络设备101的载波频率为F1,第二网络设备102的载波频率为F2,以图2A所示的载波频率的覆盖场景示意图为例,第一网络设备101和第二网络设备102共站部署,F1和F2同覆盖;以图2B所示的载波频率的覆盖场景示意图为例,第一网络设备101和第二网络设备102共站部署,F1和F2不同覆盖;以图2C所示的载波频率的覆盖场景示意图为例,第一网络设备101和第二网络设备102共站部署,F1和F2相互补盲;以图2D所示的载波频率的覆盖场景示意图为例,第一网络设备101和第二网络设备102共站部署,F1和F2不同覆盖,且存在射频拉远头(Remote Radio Head,RRH);以图2E所示的载波频率的覆盖场景示意图为例,第一网络设备101和第二网络设备102共站部署,F1和F2不同覆盖,且存在直放站。
基于图1所示的通信系统的架构示意图,请参见图3,图3是本发明实施例提供的一种功率余量报告方法,该方法包括但不限于如下步骤:
步骤S301:通信设备确定使用第一成员载波的第一时隙上报功率余量,第一成员载波的时隙长度小于第二成员载波的时隙长度。
具体的,可以通过预定义或者网络配置的方式确定上报功率余量的CC及其时隙,例如可以确定在CA所包含的时隙长度最小的CC上的上行(Up Link,UL)资源中发送功率余量。基于此,通信设备需要上报激活的各个CC的功率余量时,可以将各个激活的CC的时隙长度进行比较,以确定时隙长度最小的CC,进而确定使用时隙长度最小的CC的第一时隙上报功率余量。
以图4所示的CC的结构示意图为例,CA中激活的CC包括CC1和CC2,通信设备可以确定CC1的时隙长度大于CC2的时隙长度,则通信设备可以确定使用CC2的时隙上报CC1的功率余量和CC2的功率余量。示例性的,通信设备可以使用CC2的slot2上报CC1的功率余量和CC2的功率余量。
可选的,当第一成员载波接收到上行授权(UL grant)的第五时隙早于第二成员载波接收到上行授权的第四时隙时,通信设备可以确定使用第五时隙所调度的第一时隙上报功率余量。
由于不同CC的处理时间不同,在不同CC上,调度上行授权的物理下行控制信道(Physical Downlink Control Channel,PDCCH)和授权的UL资源之间的时延可能是不同的。以图4所示的CC的结构示意图为例,通信设备内部触发了一个PHR之后,通信设备在CC1的slot 2上收到调度UL grant的PDCCH,将准备在CC1的slot 6上发送PHR,且在CC2的slot1收到调度UL grant的PDCCH,将准备在CC2的slot5上发送PHR。由于CC2的slot1在时间上比CC1的slot2更早,因此通信设备可以确定在CC2的slot5发送PHR。
本发明实施例可以在接收到上行授权时就开始准备计算用于计算功率余量的时隙的功率余量,提高功率余量计算效率。
可选的,通信设备确定上报功率余量的成员载波及其时隙的方法可以是网络配置或者预定义的。以网络配置为例,在CA情况下,网络设备配置通信设备使用最早接收到上行授权的成员载波上报功率余量,则通信设备可以检测第一成员载波上被调度上行资源的第一时隙是否早于第二成员载波上被调度上行资源的第六时隙,当第一成员载波接收到上行授权的第五时隙早于第二成员载波接收到上行授权的第四时隙时,通信设备可以确定使用第五时隙所调度的第一时隙上报功率余量。在DC情况下,第一网络设备和第二网络设备可以分别配置自己的CC的功率余量上报方式,例如第一网络设备和第二网络设备可以分别配置通信设备使用最早接收到上行授权的成员载波上报功率余量,则通信设备可以根据各个网络配置分别确定向第一网络设备和第二网络设备上报功率余量的具体方式,其中DC情况下针对任一网络设备,通信设备根据网络配置上报功率余量的具体方式和CA情况下通信设备根据网络配置上报功率余量的具体方式相同,在此不再赘述。
可选的,当第一成员载波上被调度上行资源的第一时隙早于第二成员载波上被调度上行资源的第六时隙时,通信设备可以确定使用第一时隙上报功率余量。
以图4所示的CC的结构示意图为例,通信设备内部触发了一个PHR之后,通信设备在CC1的slot 2上收到调度UL grant的PDCCH,其调度CC1的slot 6上的UL资源,且在CC2的slot1收到调度UL grant的PDCCH,其调度CC2的slot5上的UL资源。由于CC2 的slot5在时间上比CC1的slot6更早,因此通信设备可以确定在CC2的slot5发送PHR。
本发明实施例在内部触发PHR之后,将最早调度UL资源的时隙作为上报功率余量的时隙,相对使用最早接收到上行授权的时隙所调度的时隙上报功率余量,本发明实施例上报功率余量的时延更短,可高效上报功率余量。另外,本发明实施例可适用于通信设备在CC上的UL传输不依靠上行授权的情况。
可选的,通信设备可以基于第二配置信令,检测第一成员载波上被调度上行资源的第一时隙是否早于第二成员载波上被调度上行资源的第六时隙,第二配置信令包括RRC信令、MAC控制信元或者物理层信令。
其中,第二配置信令可以是第一网络设备或者第二网络设备配置的。
也就是说,通信设备确定上报功率余量的成员载波及其时隙的方法可以是网络配置或者预定义的。以网络配置为例,在CA情况下,网络设备可以生成第二配置信令,并将第二配置信令发送给通信设备,其中第二配置信令用于指示通信设备使用最早被调度上行资源的成员载波上报功率余量,则通信设备可以基于第二配置信令,检测第一成员载波上被调度上行资源的第一时隙是否早于第二成员载波上被调度上行资源的第六时隙,当第一成员载波接收到上行授权的第五时隙早于第二成员载波接收到上行授权的第四时隙时,通信设备可以确定使用第五时隙所调度的第一时隙上报功率余量。在DC情况下,第一网络设备和第二网络设备可以分别配置自己的CC的功率余量上报方式,例如第一网络设备和第二网络设备可以分别向通信设备发送第二配置信令,则通信设备可以根据各个第二配置信令分别确定向第一网络设备和第二网络设备上报功率余量的具体方式,其中DC情况下针对任一网络设备,通信设备根据第二配置信令上报功率余量的具体方式和CA情况下通信设备根据第二配置信令上报功率余量的具体方式相同,在此不再赘述。
步骤S302:通信设备确定第二成员载波中用于计算功率余量的第二时隙,第二时隙为第二成员载波中与第一时隙重叠的时隙。
通信设备确定使用第一成员载波的第一时隙上报功率余量之后,可以确定CA所包含的其他CC中用于计算功率余量的第二时隙。具体的,当第一成员载波的时隙长度小于第二成员载波的时隙长度时,通信设备可以将第二成员载波中与第一时隙重叠的时隙作为第二时隙。以图4为例,CC1的各个时隙的时隙长度相同,且CC2的各个时隙的时隙长度相同,其中CC1的一个时隙的时隙长度是CC2的一个时隙的时隙长度的两倍,当第一时隙为CC2的slot2时,通信设备可以确定CC1中与CC2的slot2重叠的时隙为slot1,则通信设备可以将CC1的slot1确定为第二时隙。
步骤S303:通信设备基于第一时隙计算第一成员载波的功率余量,并基于第二时隙计算第二成员载波的功率余量。
通信设备可以基于第一时隙计算第一成员载波的功率余量,并基于第二时隙计算第二成员载波的功率余量。具体的,功率余量的计算方式可以为:PH=Pcmax,c-PUL power,其中PH为成员载波的功率余量,Pcmax,c为该成员载波用于计算功率余量的时隙的最大发送功率, PUL power为该成员载波用于计算功率余量的时隙的上行发送功率。
以图4为例,当第一时隙为CC2的slot12,第二时隙为CC1的slot1时,通信设备可以获取CC2的slot12的最大发送功率以及上行发送功率,将CC2的slot12的最大发送功率与CC2的slot12的上行发送功率之间的差值作为CC2的功率余量。同理,通信设备还可以获取CC1的slot1的最大发送功率以及上行发送功率,将CC1的slot1的最大发送功率与CC1的slot1的上行发送功率之间的差值作为CC1的功率余量。
需要说明的是,对于聚合的CC具有不同时隙结构(slot structure)的情况,功率余量的计算可以只考虑该slot的UL部分的UL功率。以图11所示的时隙的结构示意图为例,Type1:时隙仅包括下行(Down Link,DL)资源,则通信设备可以确定该时隙所处成员载波的功率余量为0;Type2:时隙仅包括UL资源,则通信设备可以确定该时隙所处成员载波的功率余量为该时隙的最大发送功率与该时隙的上行发送功率之间的差值;Type3:时隙包括DL资源和UL资源,则通信设备可以确定该时隙所处成员载波的功率余量为该时隙中UL部分时隙的最大发送功率与该时隙中UL部分时隙的上行发送功率之间的差值。
可选的,通信设备可以基于第一时隙的最大发送功率、配置的第一成员载波所使用波形的偏移值和第一时隙的上行发送功率,得到第一成员载波的功率余量。
可选的,通信设备可以基于第二时隙的最大发送功率、配置的第二成员载波所使用波形的偏移值和第二时隙的上行发送功率,得到第二成员载波的功率余量。
具体的,在NR中同意通信设备需要支持2种波形,即循环前缀正交频分复用(Cyclic Prefix Orthogonal Frequency Division Multiplexing,CP-OFDM)和离散傅里叶变换扩频正交频分复用(Discrete Fourier Transform-Spread OFDM,DFT-S-OFDM)。在使用CP-OFDM波形时,通信设备需要将Pcmax,c回退几个dB(例如2dB),以避免发生信号歪曲。因此,2种波形对通信设备上报的功率余量将有影响。通信设备进行CA或DC操作时,聚合的CC可能被网络设备配置不同的波形。
以第一成员载波为例,在CA操作下,网络设备可以向通信设备配置每个CC使用的波形之间的偏移值,通过RRC信令、MAC层信令或物理层信令将各个CC所使用波形的偏移值发送给通信设备,则通信设备可以将第一成员载波中第一时隙的最大发送功率减去第一成员载波所使用波形的偏移值,得到第一成员载波中第一时隙的实际最大发送功率,将该实际最大发送功率减去第一时隙的上行发送功率,得到第一成员载波的功率余量。
其中,偏移值可以是CP-OFDM波形的Pcmax,c和DFT-S-OFDM波形的Pcmax,c之间的偏移值,也可以是2个波形的通信设备期望接收功率之间的偏移值。
在DC操作下,第一网络设备可以为主基站(Master gNB,MgNB),第二网络设备可以为辅基站(Secondary gNB,SgNB),通信设备在每个网络设备下可以进行CA操作。MgNB和SgNB可以分别配置自己管理的CC的波形,MgNB和SgNB可以交换2个波形之间的偏移值,再由一个网络设备将2个基站的偏移值配置给通信设备。针对任一网络设备,通信设备可以通过上述功率余量的上报方式向该网络设备上报该网络设备的CA中各个CC的功率余量。
本发明实施例考虑CA和DC情况下CC的不同波形对PHR报告内容的影响,有助于 网络设备知悉通信设备对CC是否应用波形导致的功率回退。
步骤S304:通信设备使用第一时隙上报计算得到的第一成员载波的功率余量和第二成员载波的功率余量。
通信设备可以使用第一时隙上报计算得到的第一成员载波的功率余量和第二成员载波的功率余量。例如,当第一时隙为CC2的slot12,第二时隙为CC1的slot1时,通信设备可以使用CC2的slot12向网络设备发送CC1的功率余量和CC2的功率余量。
在图3所描述的方法中,通信设备确定使用第一成员载波的第一时隙上报功率余量,第一成员载波的时隙长度小于第二成员载波的时隙长度;将第二成员载波中与第一时隙重叠的时隙作为第二成员载波中用于计算功率余量的第二时隙;基于第一时隙计算第一成员载波的功率余量,并基于第二时隙计算第二成员载波的功率余量;使用第一时隙上报计算得到的第一成员载波的功率余量和第二成员载波的功率余量,可适用于具有不同时隙长度的成员载波的功率余量报告,提高功率余量报告的适用性。
基于图1所示的通信系统的架构示意图,请参见图5,图5是本发明实施例提供的一种功率余量报告方法,该方法包括但不限于如下步骤:
步骤S501:通信设备确定使用第一成员载波的第一时隙上报功率余量,第一成员载波的时隙长度大于第二成员载波的时隙长度。
具体的,可以通过预定义或者网络配置的方式确定上报功率余量的CC及其时隙,例如可以确定在CA所包含的时隙长度最大的CC上的上行资源中发送功率余量。基于此,通信设备需要上报激活的各个CC的功率余量时,可以将各个激活的CC的时隙长度进行比较,以确定时隙长度最大的CC,进而确定使用时隙长度最大的CC的第一时隙上报功率余量。
以图4所示的CC的结构示意图为例,CA中激活的CC包括CC1和CC2,通信设备可以确定CC1的时隙长度大于CC2的时隙长度,则通信设备可以确定使用CC1的时隙上报CC1的功率余量和CC2的功率余量。示例性的,通信设备可以使用CC1的slot1上报CC1的功率余量和CC2的功率余量。
可选的,当第一成员载波接收到上行授权的第五时隙早于第二成员载波接收到上行授权的第四时隙时,通信设备可以确定使用第五时隙所调度的第一时隙上报功率余量。
以图4所示的CC的结构示意图为例,通信设备内部触发了一个PHR之后,通信设备在CC1的slot 1上收到调度UL grant的PDCCH,将准备在CC1的slot 5上发送PHR,且在CC2的slot3收到调度UL grant的PDCCH,将准备在CC2的slot7上发送PHR。由于CC1的slot1在时间上比CC2的slot3更早,因此通信设备可以确定在CC1的slot5发送PHR。
可选的,通信设备确定上报功率余量的成员载波及其时隙的方法可以是网络配置或者预定义的。以网络配置为例,在CA情况下,网络设备配置通信设备使用最早接收到上行授权的成员载波上报功率余量,则通信设备可以检测第一成员载波上被调度上行资源的第一时隙是否早于第二成员载波上被调度上行资源的第六时隙,当第一成员载波接收到上行授权的第五时隙早于第二成员载波接收到上行授权的第四时隙时,通信设备可以确定使用第五时隙所调度的第一时隙上报功率余量。在DC情况下,第一网络设备和第二网络设备 可以分别配置自己的CC的功率余量上报方式,例如第一网络设备和第二网络设备可以分别配置通信设备使用最早接收到上行授权的成员载波上报功率余量,则通信设备可以根据各个网络配置分别确定向第一网络设备和第二网络设备上报功率余量的具体方式,其中DC情况下针对任一网络设备,通信设备根据网络配置上报功率余量的具体方式和CA情况下通信设备根据网络配置上报功率余量的具体方式相同,在此不再赘述。
可选的,当第一成员载波上被调度上行资源的第一时隙早于第二成员载波上被调度上行资源的第六时隙时,通信设备可以确定使用第一时隙上报功率余量。

可选的,通信设备可以确定第三成员载波中用于计算功率余量的第三时隙,第三时隙为第三成员载波的参考时隙。
通信设备确定使用第一成员载波的第一时隙上报功率余量之后,当第一成员载波的时隙长度大于第三成员载波的时隙长度时,通信设备可以将第三成员载波中预先定义的参考时隙作为第三时隙。以图4为例,第一成员载波为CC2,第三成员载波为CC3,CC1的各 个时隙的时隙长度相同,且CC3的各个时隙的时隙长度相同,其中CC1的一个时隙的时隙长度是CC3的一个时隙的时隙长度的两倍,当第一时隙为CC1的slot1,且预先定义的参考时隙为成员载波激活后的第一个时隙时,通信设备可以将CC3的slot1确定为第三时隙。
可选的,通信设备可以根据配置的关于所述第三成员载波的时隙确定规则,确定第三时隙。其中,时隙确定规则可以通过第一配置信令传输,第一配置信令包括RRC信令、MAC控制信元或者物理层信令中的至少一种。以图4为例,CC1的各个时隙的时隙长度相同,且CC3的各个时隙的时隙长度相同,其中CC1的一个时隙的时隙长度是CC3的一个时隙的时隙长度的两倍,当第一时隙为CC1的slot1,且时隙确定规则为成员载波激活后的第n个时隙时,通信设备可以将CC3的slotn确定为第三时隙,其中n为正整数。

通信设备可以基于第一时隙计算第一成员载波的功率余量,基于第二时隙计算第二成员载波的功率余量,并基于第三时隙计算第三成员载波的功率余量。
以图4为例,当第一时隙为CC2的slot12,第二时隙为CC1的slot1,第三时隙为CC3的slot3时,通信设备可以获取CC2的slot12的最大发送功率以及上行发送功率,将CC2的slot12的最大发送功率与CC2的slot12的上行发送功率之间的差值作为CC2的功率余量。同理,通信设备还可以获取CC1的slot1的最大发送功率以及上行发送功率,将CC1的slot1的最大发送功率与CC1的slot1的上行发送功率之间的差值作为CC1的功率余量。通信设备还可以获取CC3的slot3的最大发送功率以及上行发送功率,将CC3的slot3的最大发送功率与CC3的slot3的上行发送功率之间的差值作为CC3的功率余量。

可选的,通信设备可以基于第三时隙的最大发送功率、配置的第三成员载波所使用波形的偏移值和第三时隙的上行发送功率,得到第三成员载波的功率余量。
以第一成员载波为例,在CA操作下,网络设备可以向通信设备配置每个CC使用的波形之间的偏移值,通过RRC信令、MAC层信令或物理层信令将各个CC所使用波形的偏移值发送给通信设备,则通信设备可以将第一成员载波中第一时隙的最大发送功率减去第一成员载波所使用波形的偏移值,得到第一成员载波中第一时隙的实际最大发送功率,将该实际最大发送功率减去第一时隙的上行发送功率,得到第一成员载波的功率余量。
其中,偏移值可以是CP-OFDM波形的Pcmax,c和DFT-S-OFDM波形的Pcmax,c之间的偏移值,也可以是2个波形的通信设备期望接收功率之间的偏移值。
在DC操作下,第一网络设备可以为主基站(Master gNB,MgNB),第二网络设备可以为辅基站(Secondary gNB,SgNB),通信设备在每个网络设备下可以进行CA操作。MgNB和SgNB可以分别配置自己管理的CC的波形,MgNB和SgNB可以交换2个波形之间的偏移值,再由一个网络设备将2个基站的偏移值配置给通信设备。针对任一网络设备,通信设备可以通过上述功率余量的上报方式向该网络设备上报该网络设备的CA中各个CC 的功率余量。
步骤S805:通信设备使用第一时隙上报计算得到的第一成员载波的功率余量、第二成员载波的功率余量以及第三成员载波的功率余量。
通信设备可以使用第一时隙上报计算得到的第一成员载波的功率余量、第二成员载波的功率余量以及第三成员载波的功率余量。例如,当第一时隙为CC2的slot12,第二时隙为CC1的slot1,第三成员载波中用于计算功率余量的时隙为CC3的slot3时,通信设备可以使用CC2的slot12向网络设备发送CC1的功率余量、CC2的功率余量和CC3的功率余量。
