Description

上行功率分配方法及装置、存储介质、终端
本申请要求2020年4月17日提交中国专利局、申请号为202010307168.2、发明名称为“上行功率分配方法及装置、存储介质、终端”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
本发明涉及通信技术领域，具体地涉及一种上行功率分配方法及装置、存储介质、终端。
背景技术
通常而言，在非独立组网(Non-Standalone operation mode，简称NSA)下进行NR与长期演进(Long Term Evolution，简称LTE)的上行发送时，针对NR与LTE的上行发送信号的重叠(overlap)部分，新无线(New Radio，简称NR)终端会对重叠部分NR的上行发送功率(可简称为上行功率)进行调整，以确保NR与LTE上行发送功率之和不超出规定范围。
在NSA下进行NR和LTE的上行发送主要包括两种场景：EN-DC和NE-DC。其中，EN-DC是指第四代移动通信技术(4 Generation，简称4G)无线接入网与5G NR的双连接，具体是指以演进的UMTS陆地无线接入(Evolved Universal Terrestrial Radio Access，简称E-UTRA)为主小区组(Master Cell group，简称MCG)、以NR为辅小区组(Secondary Cell group，简称SCG)的E-UTRA和NR双连接(E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR)。NE-DC是指5G NR与4G无线接入网的双连接，具体是指以NR为MCG、以E-UTRA为SCG的E-UTRA和NR双连接。
不论是EN-DC还是NE-DC，当出现前述上行发送存在重叠部分、 且重叠部分NR与LTE的上行发送功率之和超出限制的情形时，都无条件地降低重叠部分NR的上行发送功率，甚至在功率降低较多时主动放弃NR的发送。但是，如果此时NR上发送的是较为重要的信道(如物理随机接入信道(Physical Random Access Channel，简称PRACH))，则这种降低NR的上行发送功率甚至放弃发送的做法，对NR链路的连接性能影响较大。具体而言，会降低甚至恶化无线资源控制(Radio Resource Control，简称RRC)连接态(Connect)下NR链路的连接性能，严重时NR甚至无法驻网或掉网。

与现有技术相比，本发明实施例的技术方案具有以下有益效果：

具体实施方式
如背景技术所言，现有NSA下NR与LTE上行发送功率的分配策略存在缺陷，严重影响RRC连接态下NR链路的连接性能。
具体而言，在移动通信终端进行NSA的NR与LTE上行并发过程中，NR和LTE都有各自的发送功率与时序。如果两者发送信号在时间上存在重叠，并且重叠部分的两者发送功率之和超出了限制范围，则基于现有技术，需要对重叠部分NR的发送进行处理。
现有的常规处理方式是：根据第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)协议38.213和38.101-3里的相关描述，NSA不同场景下NR与LTE发送功率之和的最大值，在EN-DC场景下为
Figure PCTCN2021085763-appb-000001
而在NE-DC场景下则为
Figure PCTCN2021085763-appb-000002
NR与LTE的重叠部分发送功率之和一旦超出上述配置的最大值，则直接降低NR的发送功率。并且，在EN-EC场景下，如果NR发送功率下降幅度超过了X SCALE，则可以直接放弃NR的发送。
但是，由于NR上行发送的信道有可能较为重要，直接降低发送功率甚至打掉发送的话，会导致RRC连接态下NR链路的连接性能下降，严重时NR甚至无法驻网或掉网。
为解决上述技术问题，本发明实施例提供一种上行功率分配方法，包括：对于即将发送的第一上行信道，确定所述第一上行信道的重叠集合，其中，所述重叠集合为与所述第一上行信道在时间上相重叠的上行信道集合，所述与所述第一上行信道在时间上相重叠的上行信道中的至少一部分与所述第一上行信道属于不同的通信系统；当所述重叠集合中各上行信道的上行功率之和大于预设最大发送总功率时，至少根据信道类型、上行信号中携带的信息、载波类型以及周期性确定所述重叠集合中各上行信道的优先级排序；按照所述优先级排序重新分配所述重叠集合中各上行信道的上行功率，直至所述重叠集合中各上行信道的上行功率之和小于等于所述预设最大发送总功率，其中，优先级越低的上行信道，所述上行信道的上行功率调整量越大；根据重新分配结果更新所述第一上行信道的上行功率。其中，即将发送指的是将要发送，或者准备进行发送；不同的通信系统指的是采用不同通信协议的通信系统，例如LTE通信系统和NR通信系统为不同的通信系统。
当NSA下NR与LTE上行并发过程发生重叠且重叠部分NR和LTE的上行发送功率之和超过限制时，采用本实施例方案的NR终端分别评估重叠部分NR与LTE上行发送信道的类型与重要性，并据此优化分配NR与LTE的上行发送功率。由此，能够在基本不影响RRC连接态下LTE链路连接性能的前提下，降低对RRC连接态下NR链路连接性能的影响。具体而言，针对重叠集合内属于LTE通信系统的上行信道和属于NR通信系统的上行信道，按信道类型等考量因素综合排序，以确保承载有如链路连接性能相关信令的NR上行信道和LTE上行信道的上行功率均能得到有效保证。避免为了确保LTE链路的连接性能而一味地降低NE链路的连接性能。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例的一种上行功率分配方法的流程图。
本实施例方案可以应用于NSA下NR和LTE并发的应用场景。具体而言，可以包括NE-DC场景和EN-DC场景。
本实施例方案可以由处于上述场景的用户设备执行，如NR终端。以在出现重叠且重叠部分各上行信道的上行功率之和超出限制时，能够在确保LTE链路连接性能的情况下，降低对NR链路连接性能的影响。
在具体实施中，下述步骤S101～步骤S104所提供的上行功率分配方法可以由用户设备中的具有功率分配功能的芯片执行，也可以由用户设备中的基带芯片执行。
具体地，参考图1，本实施例所述上行功率分配方法可以包括如下步骤：
步骤S101，对于即将发送的第一上行信道，确定所述第一上行信道的重叠集合，其中，所述重叠集合为与所述第一上行信道在时间上相重叠的上行信道集合，所述与所述第一上行信道在时间上相重叠的上行信道中的至少一部分与所述第一上行信道属于不同的通信系统；
步骤S102，当所述重叠集合中各上行信道的上行功率之和大于预设最大发送总功率时，至少根据信道类型、上行信号中携带的信息、载波类型以及周期性确定所述重叠集合中各上行信道的优先级排序；
步骤S103，按照所述优先级排序重新分配所述重叠集合中各上行信道的上行功率，直至所述重叠集合中各上行信道的上行功率之和小于等于所述预设最大发送总功率，其中，优先级越低的上行信道，所述上行信道的上行功率调整量越大；
步骤S104，根据重新分配结果更新所述第一上行信道的上行功率。
在一个具体实施中，所述步骤S101中，可以按照时间先后顺序，在即将发送某个NR或LTE上行信道之前，对该即将发送的上行信道的时间段内，已知的且尚未发送的其它LTE或NR上行信道进行判断，以确定这些上行信道是否存在时间上的重叠。
进一步，如果没有重叠，则转入NR与LTE各自内部发送功率分配的处理。如果存在重叠，则执行所述步骤S102至步骤S104。
进一步，本实施例所述重叠，可以指不同通信系统的上行信道在时间上重叠。否则，如果发生重叠的都是同一通信系统的上行信道，则仍可以转入该通信系统内部发送功率分配的处理。其中，不同的通信系统可以指NR通信系统和LTE通信系统。在实际应用中，也可以指现有或未来协议规定的其他通信系统。
在一个具体实施中，所述步骤S101中，在确定存在重叠后，对于所述第一上行信道，可以以其时域的采样点为颗粒度，按照时间先后顺序，在所述第一上行信道的时间段内，逐个采样点计算与其在时间上发生重叠的所有上行信道的发送功率之和。并判断该功率发送之和是否超出了NSA下最大发送总功率
Figure PCTCN2021085763-appb-000003
(即所述预设最大发送总功率)。
进一步地，考虑到在所述第一上行信道的时间段内，可能存在不同时间点上重叠的上行信道类型不同的情况。为区分，可以设定“重叠集合”：每个“重叠集合”里包含该时间点里所有并发的上行信道。进一步，所述重叠集合可以是能并发的上行信道最多的集合。
例如，参考图2，假设第一上行信道在整个时间段内先后与其它4个上行信道(分别记作重叠上行信道1、重叠上行信道2、重叠上行信道3和重叠上行信道4)存在时间上的重叠。其中，重叠上行信道1、重叠上行信道2、重叠上行信道3和重叠上行信道4中的一部 分可以是NR上行信道，其中的剩余部分可以是LTE上行信道。
根据图2示出的各上行信道的占用时间段可知，第一上行信道与重叠上行信道1、重叠上行信道2和重叠上行信道3在时间段1发生重叠。相应的，可以将这四个上行信道确定为“重叠集合1”。也即，重叠集合1中包括了3个能与第一上行信道并发的重叠上行信道。
进一步，第一上行信道与重叠上行信道3和重叠上行信道4在时间段2发生重叠。相应的，可以将这三个上行信道确定为“重叠集合2”。也即，重叠集合2中包括了2个能与第一上行信道并发的重叠上行信道。
进一步，计算重叠集合1中所有上行信道的上行功率之和，如果加和超出NSA下最大发送总功率
Figure PCTCN2021085763-appb-000004
则执行步骤S102。
类似的，计算重叠集合2中所有上行信道的上行功率之和，如果加和超出NSA下最大发送总功率
Figure PCTCN2021085763-appb-000005
则同样执行步骤S102。
如果重叠集合1中所有上行信道的上行功率之和以及重叠集合2中所有上行信道的上行功率之和均未超出NSA下最大发送总功率
Figure PCTCN2021085763-appb-000006
则转入NR与LTE各自内部发送功率分配的处理。
在一个具体实施中，在所述步骤S102中，NR和LTE各上行信道的优先级以及功率调整系数，可以通过系统仿真或依据场景等确定。并满足如下原则：基本不影响RRC连接态下LTE链路连接性能，并且降低对RRC连接态下NR链路连接性能的影响。
具体而言，优先级与上行信道类型、上行信号中携带的信息、载波类型以及周期性等相关。例如，在初始接入或上行链路失步时，需要发送PRACH信道进行与网侧的上行同步，故PRACH的优先级会最高。
相应的，在所述步骤S102中，可以按照PRACH的优先级最高、PUCCH的优先级次之以及PUSCH的优先级最低的顺序确定各上行信道的优先级。
进一步地，在所述步骤S102中，可以按照上行信号中携带有混合自动重传请求(Hybrid Automatic Repeat reQuest，简称HARQ)确认消息(acknowledge，简称ACK)(简称HARQ-ACK)和/或上行调度请求(Scheduling Request，简称SR)的上行信道的优先级最高、上行信号中携带有信道状态信息(Channel State Information，简称CSI)的上行信道的优先级次之，以及上行信号中未携带HARQ-ACK、上行调度请求或者CSI的上行信道的优先级最低的顺序，确定各上行信道的优先级。
进一步地，在所述步骤S102中，可以按照非周期的上行信道的优先级最高、半静态的上行信道的优先级次之以及静态的上行信道的优先级最低的顺序，确定各上行信道的优先级。
进一步地，在所述步骤S102中，可以按照关联的小区为载波聚合(Carrier Aggregation，简称CA)中的主小区(Primary Cell，简称PCell)的上行信道的优先级最高、关联的小区为载波聚合中的主辅小区(Primary Secondary Cell，简称PSCell)的上行信道的优先级次之，以及关联的小区为载波聚合中的辅小区(Secondary Cell，简称SCell)的上行信道的优先级最低的顺序，确定各上行信道的优先级。
例如，表1示出NR和LTE的各上行信道的优先级综合排序结果的一部分
序号 上行信道优先级(降序)
1 LTE PRACH@PCell
2 NR PRACH@PCell
3 LTE PUCCH with HARQ-ACK&/SR
4 LTE PUSCH with HARQ-ACK
5 NR PUCCH with HARQ-ACK&/SR
6 NR PUSCH with HARQ-ACK
7 LTE PUCCH/PUSCH with CSI
8 NR PUCCH/PUSCH with CSI
9 LTE PUSCH without HARQ-ACK/CSI
10 NR PUSCH without HARQ-ACK/CSI
…… ……
如表1所示，在EN-DC场景下，优先级从高到低依次为：主小区的LTE PRACH(LTE PRACH@PCell)；主小区的NR PRACH(NR PRACH@PCell)；主小区配置且上行信号中携带有HARQ-ACK和/或SR的LTE PUCCH(LTE PUCCH with HARQ-ACK&/SR)；主小区配置且上行信号中携带有HARQ-ACK的LTE PUSCH(LTE PUSCH with HARQ-ACK)；主小区配置且上行信号中携带有HARQ-ACK和/或SR的NR PUCCH(NR PUCCH with HARQ-ACK&/SR)；主小区配置且上行信号中携带有HARQ-ACK的NR PUSCH(NR PUSCH with HARQ-ACK)；主小区配置且上行信道中携带有CSI的LTE PUCCH或LTE PUSCH(LTE PUCCH/PUSCH with CSI)；主小区配置且上行信道中携带有CSI的NR PUCCH或NR PUSCH(NR PUCCH/PUSCH with CSI)；主小区配置且上行信号未携带HARQ-ACK和CSI的LTE PUSCH(LTE PUSCH without HARQ-ACK/CSI)；主小区配置且上行信号未携带HARQ-ACK和CSI的NR PUSCH(NR PUSCH without HARQ-ACK/CSI)。
按此优先级排序，第11行开始可以按第1至10行的规律确定主辅小区配置的各上行信道的优先级，然后确定辅小区配置的各上行信道的优先级。
在一个具体实施中，所述步骤S102还可以包括：对于信道类型相同、上行信号中携带有相同的信息、载波类型相同和/或周期性相同的多个上行信道，根据当前上行发送的场景确定所述多个上行信道的优先级顺序，其中，所述场景包括NE-DC场景和EN-DC场景。
具体地，若当前上行发送的场景为NE-DC场景，则对于信道类型相同、上行信号中携带有相同的信息、载波类型相同和/或周期性相同的多个上行信道，确定其中属于NR通信系统的上行信道的优先 级高于其中属于LTE通信系统的上行信道的优先级。
若当前上行发送的场景为EN-DC场景，则对于信道类型相同、上行信号中携带有相同的信息、载波类型相同和/或周期性相同的多个上行信道，确定其中属于LTE通信系统的上行信道的优先级高于其中属于NR通信系统的上行信道的优先级。
例如，表1是以EN-DC场景为例展现的优先级排序结果，因该场景是以LTE通信系统为主，LTE链路的连接性能更为重要。因此，表1中，同样的信道类型、上行信号携带同样信息、载波类型相同以及周期性相同的NR上行信道的优先级低于LTE上行信道的优先级。
又例如，如果在NE-DC场景中，由于此时NR链路的连接性能更为重要，此时的优先级排序可以以NR的上行信道为先。例如，同样是主小区的LTE PRACH和主小区的NR PRACH，在NE-DC场景中，主小区的NR PRACH的优先级高于主小区的LTE PRACH。
在一个具体实施中，在所述步骤S103中，通过调整NR与LTE的上行功率调整系数，来实现功率的优化分配，同时将功率和降至NSA最大发送总功率
Figure PCTCN2021085763-appb-000007
具体而言，在NSA场景下，可将NR的上行信道表示为CH NR，其上行功率(即上行发送功率)的原始计算值为P NR(CH NR)，功率调整系数α NR(CH NR)，其中0≤α NR(CH NR)≤1；将LTE的上行信道表示为CH LTE，其上行功率(即上行发送功率)的原始计算值为P LTE(CH LTE)，功率调整系数α LTE(CH LTE)，其中0≤α LTE(CH LTE)≤1。
如果NR与LTE的上行信道存在时间上的重叠，则可以通过分别调整NR的功率调整系数α NR(CH NR)以及LTE的功率调整系数α LTE(CH LTE)，来实现优化分配NR与LTE的上行功率。以同时兼顾RRC连接态下LTE链路和NR链路的连接性能。
例如，可以基于公式
Figure PCTCN2021085763-appb-000008
Figure PCTCN2021085763-appb-000009
进行优化分配。其中，
Figure PCTCN2021085763-appb-000010
如果相同时间点上存在两个以上重叠的NR或LTE上行信道，则上述公式可以扩展为
Figure PCTCN2021085763-appb-000011
Figure PCTCN2021085763-appb-000012
其中，n为存在重叠的NR上行信道数，m为存在重叠的LTE上行信道数。
在一个具体实施中，优先级越高的上行信道，所述上行信道的上行功率调整量越趋近于零。也即，优先级越高的上行信道，所述上行信道的功率调整系数越接近于1。
在一个具体实施中，所述步骤S103可以包括步骤：按照所述优先级排序，根据优先级最高的上行信道的上行功率以及所述预设最大发送总功率确定剩余可分配上行功率；基于所述剩余可分配上行功率重新分配所述重叠集合中除优先级最高的上行信道之外的剩余上行信道，以使所述剩余上行信道的上行功率之和小于等于所述剩余可分配上行功率。
进一步地，将低优先级的上行信道的上行功率除以其原上行功率，即可得到所述上行信道的功率调整系数。
优先级越低，所述上行信道的上行功率降低的越多，相应的，所述上行信道的功率调整系数越小。
例如，假设重叠集合包括两个上行信道：主小区配置的NR PRACH以及主小区配置的LTE PUSCH，但LTE PUSCH未携带HARQ-ACK和CSI。且这两个上行信道的上行功率之和超出
Figure PCTCN2021085763-appb-000013
由于此时LTE PUSCH上没有携带影响LTE链路连接性能相关的信令，且主小区配置的NR PRACH对于NR上行链路的连接性能影响较大。因此，按照优先级排序，确定NR PRACH的上行功率保持不变，而 将LTE PUSCH的上行功率降至
Figure PCTCN2021085763-appb-000014
减去NR PRACH的上行功率的剩余功率值。
在一个具体实施中，参考图2，第一上行信道在整个时间段内可能确定出多个重叠集合。
当各上行信道的上行功率之和大于预设最大发送总功率的重叠集合的数量为多个时，所述步骤S103可以包括步骤：将多个重叠集合各自的重新分配结果中所述第一上行信道的最小值确定为所述第一上行信道的更新后的上行功率。
具体而言，假设所述步骤S101中选出的上行信道的上行功率之和超出NSA最大发送总功率
Figure PCTCN2021085763-appb-000015
的重叠集合数量为N个，N大于等于2。
在执行步骤S102时，可以根据如表1所示的NR和LTE各上行信道的优先级排序，逐个对每一重叠集合中各上行信道的上行功率进行优化分配，直到N个重叠集合都完成。
在执行所述步骤S103时，可以从经过上行功率优化分配后的N个重叠集合的重新分配结果中，选取第一上行信道的上行功率的最小值作为所述第一上行信道的最终上行功率。
进一步地，可以采用同样的方式选取重叠集合中其它发生重叠的上行信道的上行功率的最小值，来更新对应上行信道的上行功率。
也即，在所述步骤S104之后，所述上行分配方法还可以包括步骤：对于多个重叠集合中除所述第一上行信道外的每一上行信道，将所述上行信道在所述多个重叠集合中的最小值确定为所述上行信道的更新后的上行功率。
在一个具体实施中，所述步骤S104可以包括步骤：将所述第一上行信道基于重新分配结果确定的上行功率记作调整后上行功率，将所述调整后上行功率与所述第一上行信道的原始上行功率之比确定为所述第一上行信道的功率调整系数；根据所述第一上行信道在即将 发送时刻的前后时隙或子帧上的上行功率，对所述功率调整系数进行微调，以使所述上行信道的上行功率在时间上平稳变化；基于调整后的功率调整系数更新所述第一上行信道的上行功率。
具体地，如果所述第一上行信道在前后时隙或子帧上也有上行传输，则可以根据优先级以及场景等，在确保功率之和不超出NSA最大发送总功率
Figure PCTCN2021085763-appb-000016
的前提下，对重新分配结果中确定的各上行信道的功率调整系数进行微调，使得前后时隙或子帧对应上行信道的上行功率变化较为平稳，不至于在时间上出现突变。
由上，当NSA下NR与LTE上行并发过程发生重叠且重叠部分NR和LTE的上行发送功率之和超过限制时，采用本实施例方案的NR终端分别评估重叠部分NR与LTE上行发送信道的类型与重要性，并据此优化分配NR与LTE的上行发送功率。由此，能够在基本不影响RRC连接态下LTE链路连接性能的前提下，降低对RRC连接态下NR链路连接性能的影响。
具体而言，针对重叠集合内属于LTE通信系统的上行信道和属于NR通信系统的上行信道，按信道类型等考量因素综合排序，以确保承载有如链路连接性能相关信令的NR上行信道和LTE上行信道的上行功率均能得到有效保证。避免为了确保LTE链路的连接性能而一味地降低NE链路的连接性能。
