Abstract
本申请公开了一种上行功率调整方法,包括:接收下行控制信息DCI;配置的开环功率参数中确定目标开环功率参数,并根据所述DCI确定闭环功率参数调整值;根据目标开环功率参数和闭环功率参数调整值确定发送功率。本申请还公开了一种相关设备。采用本申请实施例解决了在重传时发生URLLC和eMBB冲突时如何进行功率调整的问题。
Description
本申请涉及通信领域,尤其涉及一种上行功率调整方法及相关设备。
目前的新无线(NR,new radio)系统引入了超可靠低时延通信(Ultra-reliable low latency communication,URLLC)和增强型移动带宽(Enhanced Mobile Broadband,eMBB)两种业务,URLLC的特征是在极端的时延内(例如,1ms)实现超高可靠性(例如,99.999%)的传输,eMBB的特征是对时延不敏感,但传输数量可以很大。对于URLLC和eMBB共存的场景,为了实现URLLC即时传输,URLLC和eMBB会发生冲突,即URLLC占用已经分配给eMBB的资源。URLLC和eMBB传输发生冲突时,URLLC和eMBB会相互干扰对方,从而影响URLLC和eMBB的解调性能,重传可以克服这一影响,但是会导致URLLC的传输时延增大。
对于上行URLLC和eMBB传输冲突的问题。有两种主流解决方式:1)停止eMBB传输,降低对URLLC的干扰。2)提高URLLC发送功率,即使eMBB干扰存在,也能保证URLLC的接收信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)满足解调需求。前者干扰消除彻底,但需要增加eMBB终端复杂度。后者通过提高有用信号功率,保持接收SINR,且仅需要URLLC做增强。
无线系统中的上行功率控制是非常重要的,通过上行功控,可以使得小区中的UE既保证上行所发送数据的质量,又尽可能减少对系统中其他用户的干扰,延长UE电池的使用时间。NR Rel 15系统中,同小区内不同用户之间的上行数据是正交的,因此,NR Rel 15系统采用的上行功率控制,主要考虑通过功率控制来使得上行传输适应不同的无线传输环境,包括路损、阴影衰落等。NR Rel 15采用一种开环和闭环控制结合的方式。
但是,对于使用动态调度的CG-PUSCH进行数据重传发生URLLC和eMBB冲突时,调整发送功率可以解决URLLC和eMBB传输冲突的问题,但现有技术并未给出如何解决URLLC的功率调整问题。

参见图1,图1为本申请实施例提供的一种上行功率调整方法的应用场景示意图。如图1所示,该应用场景中包括网络设备10和终端设备20。图1所示的应用场景具体可以应用在5G通信系统或后续演进的通信系统中。
上述网络设备10可以为下一代通信的基站,如5G的gNB或小站、微站,传输接收点(transmission reception point,TRP)等。
上述终端设备20可以是用户设备(User Equipment,UE),即一种向用户提供语音和/或数据连通性的设备,还可以是具有无线连接功能的手持式设备或车载设备等。常见的终端设备20包括:手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、物联网设备,可穿戴设备(例如,智能手表、智能手环、计步器)等。

参见图2,图2为本申请实施例提供的一种上行功率调整方法的流程示意图。如图2所示,该方法包括:
S201、接收DCI。
在一个示例中,在接收DCI之前,接收功率参数配置信息,该功率参数配置信息配置有开环功率参数。
可以理解的是,DCI还可以用于指示终端设备传输数据的方式,比如使用的时频资源等。
其中,DCI所在的PDCCH的CRC是由CS-RNTI加扰的,并且DCI中新数据指示(New Data Indicator)NDI域的值为1。
S202、根据DCI从功率参数配置信息配置的开环功率参数中确定目标开环功率参数,并根据DCI确定闭环功率参数调整值。
在一个可行的实施例中,若功率参数配置信息配置的开环功率参数为上行动态传输使用的开环功率参数,且功率参数配置信息配置的开环功率参数包括p0-AlphaSets和无调度授权时的P0,根据DCI从功率参数配置信息配置的开环功率参数中确定目标开环功率参数,包括:
若DCI中存在开环功率参数指示信息,将功率参数配置信息配置的开环功率参数中由开环功率参数指示信息指示的开环功率参数确定为目标开环功率参数;
若DCI中不存在开环功率参数指示信息,将功率参数配置信息配置的开环功率参数中的一个开环功率参数确定为目标开环功率参数。
具体地,当功率参数配置信息配置的开环功率参数中只包括无调度授权时的P0和p0-AlphaSets时,开环功率参数指示信息是通过1比特位的不同取值来实现指示功率参数配置。若该1比特位取值为1,则开环功率参数指示信息所指示的开环功率参数为无调度授权时的P0,若该1比特位取值为0,则开环功率参数指示信息所指示的开环功率参数为p0-AlphaSets。
当然,还可以是若该1比特位取值为0,则开环功率参数指示信息所指示的开环功率参数为无调度授权时的P0,若该1比特位取值为1,则开环功率参数指示信息所指示的开环功率参数为p0-AlphaSets。
当功率参数配置信息配置的开环功率参数中不仅包括功率参数配置无调度授权时的P0和p0-AlphaSets,还包括其他功率参数配置时,环功率参数指示信息是通过多个比特位的不同取值来实现指示不同的功率参数配置。具体方法同上,在此不再叙述。
在一个可行的实施例中,若功率参数配置信息配置的开环功率参数为上行动态传输使用的开环功率参数,根据调度DCI从功率参数配置信息中确定开环功率参数,包括:
若DCI包括开环功率参数指示信息,将功率参数配置信息配置的开环功率参数中由开环功率参数指示信息指示的开环功率参数确定为目标开环功率参数;
若DCI中不存在开环功率参数指示信息,将功率参数配置信息配置的开环功率参数中的一个开环功率参数确定为目标开环功率参数。
在本实施例中,功率参数配置信息配置的开环功率参数包括多个开环功率参数,可建立开环功率参数指示信息所指示的不同值与多个开环功率参数之间的映射关系,因此可通过开环功率参数指示信息得到目标开环功率参数。
在一个可行的实时例中,功率参数配置信息配置的开环功率参数为上行半持续传输的初传使用的开环功率参数。
可选地,功率参数配置信息配置的开环功率参数为上行半持续传输的重传时使用的开环功率参数。
在功率参数配置信息配置的开环功率参数为上行半持续传输的初传时使用的开环功率参数的情况下,进行上行半持续传输的初传和重传时使用的开环换功率参数为同一个功率 参数配置,一般为p0-PUSCH-Alpha。
在一个可行的实施例中,功率参数配置信息配置的开环功率参数包括p0-PUSCH-Alpha,且功率参数配置信息配置的开环功率参数为上行半持续传输的初传时使用的开环功率参数,根据DCI从功率参数配置信息配置的开环功率参数中确定目标开环功率参数,包括:
若DCI不包括开环功率参数指示信息,则将功率参数配置信息配置的开环功率参数中一个开环功率参数确定为目标开环功率参数。一般来说,该开环功率参数为功率参数配置p0-PUSCH-Alpha;
若DCI包括开环功率参数指示信息,则将功率参数配置信息配置的开环功率参数中由开环功率参数指示信息指示的开环功率参数确定为目标开环功率参数。
在一个可行的实施例中,p0-AlphaSets包括P0参数配置和/或alpha参数配置;
功率参数配置信息配置的开环功率参数中的每个包括P0参数配置和/或alpha参数配置;
其中,P0参数配alpha参数配置同时生效或只有P0参数配置生效。
其中,由于功率参数配置信息配置的开环功率参数包括p0-PUSCH-Alpha,可选地还可以包括其他开环功率参数,因此功率参数配置信息配置的开环功率参数中的每个包括P0参数配置和/或alpha参数配置具体是指不仅是p0-PUSCH-Alpha包括P0参数配置和/或alpha参数配置,还可以是其他开环功率参数包括P0参数配置和/或alpha参数配置
在一个可行的实施例中,DCI还包括闭环功率参数指示信息,闭环功率参数调整值为当前闭环功率参数,该当前闭环功率参数为上述闭环功率参数指示信息所指示的功率参数,或者;
闭环功率参数调整值为当前闭环功率参数与历史闭环功率参数之和,或者;
闭环功率参数调整值为上述开环功率参数对应的闭环功率参数的历史值与当前闭环功率参数之和。
假设闭环功率参数指示信息由2比特位来实现,分别对应的取值为00,01,10和11,闭环功率参数集合为{step0,step1,step2,step3},该集合中包含4个闭环功率参数,可通过2bit的闭环功率参数指示信息分别指示4个闭环功率参数。比如00对应step0,01对应step1,10对应step2,11对应step3。
假设协议约定或高层信息配置的开环功率参数集合为{P
00,P
01}和闭环功率参数为(step0,step1,step2,step3)。
由开环功率参数指示bits(A),和闭环功率参数指示bits(B)组成的方法指示功率信息。
网络设备在DCI中使用3bit指示功率控制信息,其中1bit指示开环功率参数(C),0,1分别对应开环功率参数集合中的1个;2bit指示闭环功率参数(D),00,01,10,11分别对应闭环功率参数集合中的1个。
下表1为功率控制信息与开环功率参数及闭环功率参数之间的对应关系表。
表1
网络测设备发送的功率控制信息bit为A=0,B=00,A=0指示目标开环功率参数为P
00,B=00指示当前闭环功率参数为step0。
网络测设备发送的功率信息bit为A=1,B=00,A=1指示目标开环功率参数为P
01,B=00指示闭环功率控制参数为step0。
依次类推,A指示目标开环功率参数,B指示闭环功率参数,在计算发送功率时,两种参数都需要使用
S203、根据开环功率参数和闭环功率参数调整值确定发送功率。
在获取目标开环功率参数和闭环功率参数调整值后,可根据以下公式计算得到发送功率。
其中,i是一次PUSCH传输的索引,j是开环功率控制参数索引(包括目标功率
和路损因子α
b,f,c(j));q
d是用于进行路损测量的参考信号的索引,用于得到路损值PL
b,f,c(q
d),也是一个开环功率参数;f
b,f,c(i,l)是闭环功率控制调整因子,其中l是闭环功率控制进程。
可以看出,在本申请的实施例中,接收DCI;根据DCI从功率参数配置信息配置的开环功率参数中获取目标开环功率参数,并根据DCI获取闭环功率参数调整值;根据目标开环功率参数和闭环功率参数调整值确定发送功率。采用本申请实施例解决了在重传时发生URLLC和eMBB冲突时如何进行功率调整的问题,从而克服了URLLC和eMBB冲突时两者之间的信号干扰问题。
