在本公开的实施例的描述中,术语“包括”及其类似用语应当理解为开放性包含,即“包括但不限于”。术语“基于”应当理解为“至少部分地基于”。术语“一个实施例”或“该实施例”应当理解为“至少一个实施例”。术语“第一”、“第二”等等可以指代不同的或相同的 对象。
本公开的实施例可以根据任何适当的通信协议来实施,包括但不限于,第三代(3rd Generation,3G),第四代(4G)和第五代(5G)等蜂窝通信协议、诸如电气与电子工程师协会(Institute of Electrical and Electronics Engineers,IEEE)802.11等的无线局域网通信协议、和/或目前已知或者将来开发的任何其他协议。
本公开实施例的技术方案应用于遵循任何适当通信协议的通信系统,例如:通用分组无线业务(General Packet Radio Service,GPRS)、全球移动通信系统(Global System for Mobile Communications,GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution,EDGE)、通用移动通信系统(Universal Mobile Telecommunications Service,UMTS)、长期演进(Long Term Evolution,LTE)系统、宽带码分多址系统(Wideband Code Division Multiple Access,WCDMA)、码分多址2000系统(Code Division Multiple Access,CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access,TD-SCDMA)、频分双工(Frequency Division Duplex,FDD)系统、时分双工(Time Division Duplex,TDD)、第五代(5G)系统或新无线(New Radio,NR),等等。
出于说明的目的,下文中以5G的第三代合作伙伴计划(3GPP)通信系统为背景来描述本公开的实施例。然而,应当理解,本公开的实施例不限于被应用到5G的3GPP通信系统,而是可以被应用到任何存在类似问题的通信系统中,例如无线局域网(WLAN)、有线通信系统、或者将来开发的其他通信系统等。
在本公开中使用的术语“终端设备”指能够与网络设备之间或者彼此之间进行有线或无线通信的任何终端设备。终端设备有时可以称为用户设备(User Equipment,UE)。终端设备可以是任意类型的移动终端、固定终端或便携式终端。作为示例,终端设备可以包括移动手机、站点、单元、设备、移动终端(Mobile Terminal,MT)、订阅台、便携式订阅台、互联网节点、通信器、台式计算机、膝上型计算机、笔记本计算机、平板计算机、个人通信系统设备、个人导航设备、个人数字助理(Personal Digital Assistant,PDA)、定位设备、无线电广播接收器、电子书设备、游戏设备、物联网(Internet of Things,IoT)设备、车载设备、飞行器、虚拟现实(Virtual Reality,VR)设备、增强现实(Augmented Reality,AR)设备、可穿戴设备、5G网络中的终端设备或者演进的公用陆地移动网络(Public Land Mobile Network,PLMN)中的任何终端设备、可用于通信的其他设备、或者上述的任意组合。本公开的实施例对此并不做限定。
在本公开中使用的术语“接入网设备”是可以用于与终端设备通信的实体或节点。接入网设备可以是部署在无线接入网中为移动终端提供无线通信功能的装置,例如可以是无线接入网(Radio Access Network,RAN)网络设备。接入网设备可以包括各种类型的基站。作为示例,接入网设备可以包括各种形式的宏基站、微基站、微微基站、毫微微基站、中继站、接入点、远程无线电单元(Remote Radio Unit,RRU)、射频头(Radio Head,RH)、远程无线电头端(Remote Radio Head,RRH)等等。在采用不同的无线接入技术的系统中,接入网设备的名称可能会有所不同,例如在长期演进系统(Long Term Evolution,LTE)网络中称为演进的节点B(evolved NodeB,eNB或eNodeB),在3G网络中称为节点B(NodeB,NB),在5G网络中可以称为g节点B(gNB)或NR节点B(NR NB),等等。在某些场景下,接入网设备可以包含集中单元(Central Unit,CU)和/或分布单元(Distributed Unit,DU)。CU和DU可以放置在不同的地方,例如:DU拉远,放置于高话务量的区域,CU放置于中心机 房。或者,CU和DU也可以放置在同一机房。CU和DU也可以为一个机架下的不同部件。为方便描述,本公开后续的实施例中,上述为移动终端提供无线通信功能的装置统称为接入网设备,本公开的实施例不再具体限定。
在本公开中使用的术语“联合信道估计(Joint Channel Estimation,JCE)”可以用于实现覆盖增强(Coverage Enhancement,CE)。联合信道估计可以用于物理上行共享信道(Physical Downlink Shared Channel,PUSCH)之间,或者可以用于物理上行控制信道(Physical Uplink Control Channel,PUCCH)之间,或者可以用于PUSCH与PUCCH之间,或者可以用于其他上行传输之间。联合信道估计可以用于一次调度或不同次调度的重复之间,也可以用于不同的调度之间。联合信道估计可以在跨若干时隙或符号的时域窗口(Time Domain Window,TW)上进行,并且进行联合信道估计的条件是需要保持相位的连续性和发射功率的一致性。联合信道估计也可以被称为“跨时隙信道估计(Cross-Slot Channel Estimation)”或者“解调参考信号捆绑(Demodulation Reference Signal bundling,DMRS bundling)”等。为方便描述,本公开后续的实施例中,基于“联合信道估计”进行阐述。
在本公开中使用的术语“时隙(slot)”是数据调度的时间单位。在无线通信系统(如5G NR)中存在多种调度时间单位,例如,帧(frame)、子帧(subframe)、时隙和符号(symbol)等。一般地,帧的时间长度为10ms,包括10个子帧,每个子帧对应的时间长度为1ms。每个子帧由若干个时隙组成。在正常循环前缀下,一个时隙包括14个符号;在扩展循环前缀下,一个时隙包括12个符号。符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。应注意的是,本公开实施例中的时隙,可以是包含14个符号的时隙,也可以是微时隙(mini-slot),下文中不再特别区分。
在本公开中使用的术语“重复(repetition)”可以是PUSCH和/或PUCCH传输时重复传输的次数。重复可以是重复因子、重复次数、重复传输时隙数等,其是通过无线资源控制(Radio Resource Control,RRC)或者通过下行控制信息(Downlink Control Information,DCI)的方式进行配置的。对于PUSCH而言,存在两种重复类型:重复类型A(repetition type A)和重复类型B(repetition type B)。重复类型A是在每个时隙上发送一次重复,且在每个时隙上占用位置和数目都相同的连续的符号,在重复类型A中,RRC或DCI配置的重复因子等于重复次数,也等于重复传输时隙数。在重复类型B中,RRC或DCI配置的重复因子是指名义重复(nominal repetition)的次数,每个名义重复时域资源分配的符号数目相同,且相邻名义重复的时域资源是连续的,名义重复也可以称为标称重复。由于重复类型B的传输不能使用无效符号(invalid symbol)并且不能跨时隙边界(slot boundary),因此重复类型B的名义重复在遇到无效符号或时隙边界时,需要围绕无效符号或时隙边界被切分成实际重复(actual repetition)。对于PUCCH而言,存在一种重复类型,PUCCH的重复与PUSCH的重复类型A是类似的。
在本公开中使用的术语“传输时机(Transmission Occasion,TO)”是时域上的表示。对于PUSCH重复类型A或者对于PUCCH重复而言,TO可以是一次重复所占用的时域资源,例如一个时隙。对于PUSCH重复类型B而言,TO可以是一次实际重复所占用的时域资源,或者可以是一个时隙。
在目前的无线通信系统中,终端设备在进行上行传输前,需要先确定发射功率。但是目前的方案中,终端设备确定发射功率时没有考虑诸如联合信道估计等因素,导致所确定的发射功率准确度低,影响了上行传输的效率。
本公开的实施例提供了一种传输方案。该方案中终端设备能够基于时域窗口来确定发射功率,使得所确定的发射功率更加准确,保证了上行传输的效率。以下通过图1至图8更加详细地描述根据本公开的实施例。
图1示出了本公开实施例可实现在其中的通信系统100的一个示意图。如图1所示,该系统100包括接入网设备110和终端设备120,接入网设备110和终端设备120之间可以进行通信。
接入网设备110可以向终端设备120配置高层信令,其中高层信令是指高层协议层发出的信令,高层协议层为物理层以上的至少一个协议层。示例性地,高层协议层可以包括以下协议层中的至少一个:媒体接入控制(Medium Access Control,MAC)层、无线链路控制(Radio Link Control,RLC)层、分组数据会聚协议(Packet Data Convergence Protocol,PDCP)层、无线资源控制(Radio Resource Control,RRC)层和非接入层(Non Access Stratum,NAS)等。
图2示出了根据本公开的实施例的传输方法200的一个示意流程图。作为示例,方法200可以实现在图1所示的终端设备120处。为了便于理解,以下以终端设备120为例对传输方法200进行描述,但这仅仅是示例性的,无意对本公开的实施例进行任何限制。
方法200开始于框210。在210,终端设备120基于当前传输时机之前的时域窗口,确定在当前传输时机的功率控制调整值(power control adjustment state),其中该时域窗口包括至少两个传输时机。
可理解,当前传输时机是需要进行功率控制以重新确定发射功率的传输时机。一般地,时域窗口可以覆盖至少两个传输时机,在时域窗口的起始传输时机需要进行功率控制。
本公开实施例中,时域窗口内的至少两个传输时机可以具有相同发送特征信息,其中相同发送特征信息包括以下中的至少一项:相同的发射预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)预编码器、相同的发射功率、相同的频域资源占用(如物理资源块(Physical Resource Block,PRB))、相位连续性、相同的天线端口等。
举例来说,时域窗口内的至少两个传输时机具有相同的发射功率意味着:在时域窗口的非起始传输时机不进行功率控制或功率调整,这样才能够使得时域窗口内的各个传输时机的发射功率是相等的。
本公开实施例中,时域窗口可以用于联合信道估计,或者可以用于在时域窗口内发射功率不变的其他场景。本公开实施例中,时域窗口也可以被称为时间窗口、联合传输时机、不变传输时机或其他等。本公开实施例中,功率控制调整值也可以被称为功率控制调整状态值或者功率控制调整状态参数或者功率控制调整状态项或功率控制调整状态或功率控制调整参数或其他等,本公开对此不限定。
图3示出了根据本公开实施例的用于终端设备传输的一个时域示意图300。在图3中,示出了时域窗口310,且包括4个TO,分别为TO1至TO4。可理解,时域窗口310的起始传输时机为TO1 301,且时域窗口310之后的当前传输时机为TO5 302。也就是说,起始传输时机301是时域窗口310内的第一个TO,而当前传输时机302是时域窗口310之后的第一个TO。
在一些示例中,当前传输时机可以是时域窗口之后的另一时域窗口的起始传输时机。如图3所示,时域窗口310之后是时域窗口320,时域窗口320包括4个TO,分别为TO5至TO8。当前传输时机TO5在时域窗口310之后,且当前传输时机TO5是时域窗口320的起始 传输时机。
可理解,在一些实施例中,一个TO可以对应于一个时隙,例如在PUSCH重复类型A的场景中。
图4示出了根据本公开实施例的用于终端设备传输的另一个时域示意图400。在图4中,示出了时域窗口410,且包括4个TO,分别为TO1至TO4。可理解,时域窗口410的起始传输时机为TO1,且时域窗口410之后的当前传输时机为TO5。另外,如图4所示,在时域窗口410之后且在当前传输时机TO5之前还具有中断时域资源420。
在一些示例中,中断时域资源420的长度可以为1个或多个时隙,或者可以为1个或多个符号,等等。在一种情形下,如果时域窗口410之后存在不需要进行上行传输的一段时间,则这段时间即构成中断时域资源420,也就是说,中断时域资源420未被调度用于当前终端设备的传输。在另一种情形下,如果在进行联合信道估计的过程中,由于某些因素导致了中断,则被中断的时间构成中断时域资源420。
举例来讲,对于被配置的名义时域窗口而言,可能会因为一些因素导致名义时域窗口出现中断,从而使得一个名义时域窗口被打断,分为至少两个实际时域窗口。这样的因素包括但不限于:动态时隙格式指示(Slot Format Indication,SFI)、上行链路取消指示(UL cancellation indication,UL CI)、不同优先级的信道抢占、定时调整(诸如时间提前命令(Timing Advance command,TA command)或时间提前改变(TA change))、频偏校正、载波聚合(Carrier Aggregation,CA)、双连接(Dual-Connectivity,DC)等。
应注意的是,尽管本公开中提及了名义时域窗口和实际时域窗口,但是对名义时域窗口和实际时域窗口进行区分是为了介绍中断时域资源。名义时域窗口和实际时域窗口两者都可以是用于联合信道估计的时域窗口。
图5示出了根据本公开实施例的用于终端设备传输的又一个时域示意图500。在图5中,名义时域窗口510被打断为实际时域窗口511和实际时域窗口512,且实际时域窗口511和实际时域窗口512之间为中断时域资源520。
对于时域窗口511而言,其起始传输时机在图5中示出为起始传输时机501,该时域窗口511之后的当前传输时机在图5中示出为当前传输时机502。可见,在起始传输时机501与当前传输时机502之间,除了包括时域窗口511之外,还包括不用于联合信道估计的中断时域资源520。
本公开实施例中,在210的时域窗口可以是指实际时域窗口。可理解,本公开实施例中的当前传输时机可以是210中的时域窗口的下一个时域窗口的起始传输时机,或者可以是非时域窗口的其他传输时机。并且应理解,尽管210中的时域窗口包括至少两个传输时机,但是位于该时域窗口之后的下一个时域窗口可以包括一个或多个传输时机。例如,在图3中,当前传输时机所在的时域窗口包括4个传输时机。再例如,在图5中,当前传输时机所在的时域窗口包括1个传输时机。换句话说,本公开实施例所适用的场景可以是:当前传输时机的前一个传输时机(或称上一个传输时机)的功率没有发生变化,如没有进行功率更新或者没有进行功率更新的计算或者重新确定的功率不变。更具体地,作为一例,在进行联合信道估计的场景中,当前传输时机的前一个传输时机属于用于联合信道估计的时域窗口的非起始传输时机。
在一种实现方式中,终端设备120要进行的传输是PUSCH,则在210所确定的功率控制调整值是PUSCH功率控制调整值。
为了下文的描述,假设终端设备120在服务小区c的激活上行链路部分带宽(active Uplink Bandwidth Part,active UL BWP)b的载波f上进行PUSCH传输,并将在传输时机i上状态为l的PUSCH功率控制调整值表示为f
b,f,c(i,l)。
在一些实施例中,如果终端设备120未被配置有传输功率控制(Transmission Power Control,TPC)累加(tpc-Accumulation)参数,那么在210,终端设备120可以基于时域窗口的起始传输时机的初始功率控制调整值以及累加来确定在当前传输时机的功率控制调整值,其中累加为在与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加。
具体地,终端设备120可以获取时域窗口的起始传输时机的初始功率控制调整值;确定在与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加;基于初始功率控制调整值以及累加,确定当前传输时机的功率控制调整值。
本公开实施例中,TPC累加参数可以是通过高层信令被配置或提供的,在终端设备120未被提供有TPC累加参数时,可以基于起始传输时机的初始功率控制调整值来确定在当前传输时机的功率控制调整值。
示例性地,可以将时域窗口的起始传输时机的初始功率控制调整值表示为f
b,f,c(i-i
0,l),其可以是在确定起始传输时机的发射功率时所确定的。
示例性地,第一参数值可以是DCI中与TPC命令字段(TPC command field)参数所对应的TPC累加值,具体地为用于PUSCH的TPC累加值。在一些示例中,第一参数值可以是由调度该PUSCH传输的DCI格式中的TPC命令字段所指示的,如下表1所示。在另一些示例中,第一参数值可以是通过循环冗余校验(Cyclic Redundancy Check,CRC)由传输功率控制-物理上行共享信道-无线网络临时标识(TPC-PUSCH-RNTI)加扰的DCI格式2_2所指示的。
表1
TPC命令字段 | PUSCH的TPC累加值[dB] |
0 | -1 |
1 | 0 |
2 | 1 |
3 | 3 |
示例性地,可以将用于PUSCH的第一参数值表示为δ
PUSCH,b,f,c(m,l),进而将与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加表示为
表示集合D
i中的TPC累加值的总和,其中,集合D
i是基于第一时刻和第二时刻所确定的。
与起始传输时机关联的第一时刻可以是起始传输时机的前第S1个符号。也就是说,第一时刻位于起始传输时机之前,且第一时刻与起始传输时机可以间隔有S1个符号。换句话说,第一时刻位于起始传输时机之前的第S1个符号。例如第一时刻可以是起始传输时机i-i
0的 第前K
PUSCH(i-i
0)-1个符号,即S1=K
PUSCH(i-i
0)-1。
与当前传输时机关联的第二时刻可以是当前传输时机的前第S2个符号。也就是说,第二时刻位于当前传输时机之前,且第二时刻与当前传输时机可以间隔有S2个符号。换句话说,第二时刻位于当前传输时机之前的第S2个符号。例如第二时刻可以是当前传输时机i的第前K
PUSCH(i)个符号,即S2=K
PUSCH(i)。
可理解,i
0>0,且i
0是使得PUSCH传输时机i-i
0的第前K
PUSCH(i-i
0)-1个符号早于PUSCH传输时机i的第前K
PUSCH(i)个符号之前的最小整数,并且i-i
0是时域窗口的第一个传输时机,也称为起始传输时机。
在一些示例中,可以通过下面的方式来确定K
PUSCH(i)。如果该PUSCH传输是由DCI调度的,那么K
PUSCH(i)是该DCI对应的物理下行控制信道(Physical Downlink Control Channel,PDCCH)的最后一个符号到调度的PUSCH传输的第一个符号之间的符号数。
在另一些示例中,可以通过下面的方式来确定K
PUSCH(i)。如果该PUSCH传输是由RRC配置的,如通过“配置的授权配置(ConfiguredGrantConfig)”等,那么K
PUSCH(i)是K
PUSCH,min个符号数,其可以等于每个时隙的符号数
(例如12或14)与由PUSCH-配置的公共字段(PUSCH-ConfigCommon)中的k2字段所指示的最小值两者的乘积。
可理解,确定K
PUSCH(i-i
0)-1的方式与确定K
PUSCH(i)的方式是类似的,因此这里不再重复。
本公开实施例中,第一参数值的累加是第一时刻与第二时刻之间的所有的第一参数值的累加。该累加可以一次确定,也可以针对每个传输时机分别确定后再累加。
图6示出了根据本公开实施例的用于PUSCH的传输的一个时域示意图600。在图6中,DCI 0_x所调度的PUSCH包含8次重复传输,其中每个时隙为一个传输时机,分别为TO1至TO8。图6中示出了两个时域窗口,分别为时域窗口601和时域窗口602,其中每个时域窗口包含4个TO。另外,与时域窗口601的起始传输时机TO1相关联的第一时刻在图6中示出为第一时刻610,具体的,被示出为起始传输时机TO1前第K个符号处。与时域窗口601之后的当前传输时机TO5相关联的第二时刻在图6中示出为第二时刻620,具体的,被示出为当前传输时机TO5前第K个符号处。第一时刻至第二时刻的第一参数值的累加可以是一次得到的,如图6中的∑δ。
图7示出了根据本公开实施例的用于PUSCH的传输的另一个时域示意图700。与图6类似的,在图7中示出了两个时域窗口,分别为时域窗口701和时域窗口702,其中每个时域窗口包含4个TO。另外,与时域窗口701的起始传输时机TO1相关联的第一时刻在图7中示出为第一时刻710,以及与时域窗口701之后的当前传输时机TO5相关联的第二时刻在图7中示出为第二时刻720。第一时刻至第二时刻的第一参数值的累加可以是针对每个传输时机分别确定后再累加的。
具体的,在图7中,时域窗口701包括4个传输时机,分别为TO1至TO4。那么,可以确定与传输时机TO1关联的第一时刻到与传输时机TO2关联的第三时刻之间的第一参数值的第一累加,表示为∑δ1。可以确定与传输时机TO2关联的第三时刻到与传输时机TO3关联 的第四时刻之间的第一参数值的第二累加,表示为∑δ2。可以确定与传输时机TO3关联的第四时刻到与传输时机TO4关联的第五时刻之间的第一参数值的第三累加,表示为∑δ3。可以确定与传输时机TO4关联的第五时刻到与传输时机TO5关联的第二时刻之间的第一参数值的第四累加,表示为∑δ4。进一步地,基于第一累加、第二累加、第三累加和第四累加,得到第一时刻至第二时刻的第一参数值的累加,表示为∑δ=∑δ1+∑δ2+∑δ3+∑δ4。
对于时域窗口内的非起始传输时机而言,为了保持时域窗口内的功率一致性(即发射功率不变),非起始传输时机的发射功率不更新。在这样的非起始传输时机,可以对在非起始传输时机的功率控制调整值进行更新,但是该更新的功率控制调整值不用于确定在非起始传输时机的发射功率。
参照图7,假设时域窗口701的起始传输时机TO1的初始功率控制调整值表示为f1,那么可以基于f1以及第一累加∑δ1,确定在传输时机TO2的功率控制调整值,表示为f2。类似地,可以基于f2以及第二累加∑δ2,确定在传输时机TO3的功率控制调整值,表示为f3。可以基于f3以及第三累加∑δ3,确定在传输时机TO4的功率控制调整值,表示为f4。这样,即使对于时域窗口701的非起始传输时机,也确定了对应的功率控制调整值。应注意的是,尽管确定了在传输时机TO2、TO3和TO4的功率控制调整值,但是在确定传输时机TO2、TO3和TO4的发射功率时,是基于f1进行的,这样能够确保在时域窗口701内的功率一致性。
进一步地,确定当前传输时机TO5的功率控制调整值的方式可以是:基于传输时机TO4的功率控制调整值f4以及第四累加∑δ4,来确定当前传输时机TO5的功率控制调整值,表示为f5。可理解,由于当前传输时机TO5不再属于同一个时域窗口,在当前传输时机TO5需要进行功率更新,因此此时确定当前传输时机TO5的发射功率时所基于的是更新后的功率控制调整值f5,而不再是f1。
如此,可以得到在与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加。进一步地,本公开实施例中,可以基于初始功率控制调整值f
b,f,c(i-i
0,l)以及第一时刻至第二时刻之间接收到的所有DCI中的第一参数值的累加
确定当前传输时机的功率控制调整值f
b,f,c(i,l)。
具体地,如果(1)起始传输时机i-i
0的发射功率为最大发射功率并且
≥0,或者(2)起始传输时机i-i
0的发射功率为最小发射功率并且
那么f
b,f,c(i,l)=f
b,f,c(i-i
0,l)。否则,将初始功率控制调整值与第一参数值的累加之和作为当前传输时机的功率控制调整值,表示为:
在另一些实施例中,如果终端设备120被配置有传输功率控制TPC累加(tpc-Accumulation)参数,那么在210,终端设备120可以基于时域窗口确定比例因子;获取来自接入网设备的DCI中与TPC命令字段参数对应的第二参数值;基于第二参数值和比例 因子,确定在当前传输时机的功率控制调整值。
本公开实施例中,TPC累加参数可以是通过高层信令被配置或提供的,在终端设备120被提供有TPC累加参数时,可以基于比例因子和第二参数值来确定在当前传输时机的功率控制调整值。
示例性地,第二参数值可以是DCI中与TPC命令字段(TPC command field)参数所对应的TPC绝对值。也就是说,第二参数值可以是由调度该PUSCH传输的DCI格式中的TPC命令字段所指示的,如下表2所示。示例性地,可以将第二参数值表示为δ′
PUSCH,b,f,c(i,l)。

3 | 4 |
可以至少部分地基于间隔长度来确定比例因子,其中间隔长度为时域窗口的起始传输时机至当前传输时机之间的总长度或时域窗口的长度。
示例性地,本公开实施例中的长度表示时域长度,其可以为以下至少一项:时隙数、符号数、传输时机数、重复数等,其中重复数可以是名义重复数或实际重复数等,本公开对此不限定。
在一些示例中,时域窗口的起始传输时机至当前传输时机之间的总长度可以等于时域窗口的长度。可选地,在起始传输时机与当前传输时机之间不包括中断时域资源的情形下,起始传输时机至当前传输时机之间的总长度等于时域窗口的长度。参照图3,总长度或长度等于4个时隙或4个TO。
在另一些示例中,时域窗口的起始传输时机至当前传输时机之间的总长度可以不等于时域窗口的长度。可选地,在起始传输时机与传输时机之间包括不用于联合信道估计的中断时域资源的情形下,起始传输时机至当前传输时机之间的总长度可以不等于时域窗口的长度。参照图5,在起始传输时机501至当前传输时机502之间的总长度为3个时隙,而起始传输时机501至当前传输时机502之间的时域窗口511的长度为2个时隙。
在一些示例中,可以将时域窗口的起始传输时机至当前传输时机之间的总长度或时域窗口的长度作为间隔长度,并将间隔长度作为比例因子。具体地,可以将间隔长度去量纲之后的无量纲值作为比例因子。
举例来讲,参照图3,起始传输时机至当前传输时机之间的总长度或时域窗口的长度为4个时隙,那么比例因子可以等于4。再举例来讲,参照图5,起始传输时机至当前传输时机之间的总长度为3个时隙,那么比例因子可以等于3。再举例来讲,参照图5,时域窗口的长度为2个时隙,那么比例因子可以等于2。
在另一些示例中,可以将时域窗口的起始传输时机至当前传输时机之间的总长度或时域窗口的长度作为间隔长度;并基于间隔长度与比例因子的对应关系,获取与该间隔长度对应 的比例因子,其中该对应关系是由接入网设备的RRC所配置的或预定义的。
示例性地,接入网设备110可以通过RRC配置间隔长度与比例因子的对应关系,那么终端设备120可以基于该对应关系,确定与间隔长度对应的比例因子。
举例来讲,间隔长度与比例因子可以具有一一对应关系,例如间隔长度为3时,比例因子为X1;间隔长度为2时,比例因子为X2。再举例来讲,间隔长度与比例因子可以具有多对一的对应关系,例如间隔长度为3和4时,比例因子为X1;间隔长度为1和2时,比例因子为X2。再举例来讲,间隔长度与比例因子可以是区间与离散值的对应关系,例如间隔长度区间(0,2]对应比例因子X1。可理解,间隔长度与比例因子之间的对应关系也可以是其他的形式,这里不再罗列。
在另一些示例中,可以将时域窗口的起始传输时机至当前传输时机之间的总长度或时域窗口的长度作为间隔长度,获取来自接入网设备的RRC信令或DCI中的或者预定义的缩放因子,并基于间隔长度和缩放因子确定比例因子。
示例性地,接入网设备110可以通过RRC或者通过DCI配置一个缩放因子。或者示例性地,接入网设备110可以通过RRC配置多个缩放因子,由DCI或MAC-CE指示多个缩放因子中的一个。示例性地,可以将间隔长度与缩放因子两者的乘积作为比例因子。具体地,可以将间隔长度去量纲之后的无量纲值与缩放因子两者的乘积作为比例因子。
这样,通过上面的方式可以基于间隔长度确定比例因子,进一步地可以基于比例因子和第二参数值确定在当前传输时机的功率控制调整值。示例性地,可以将第二参数值与比例因子的乘积,作为在当前传输时机的功率控制调整值。
具体地,将比例因子表示为β,那么可以通过f
b,f,c(i,l)=β×δ′
PUSCH,b,f,c(i,l),得到在当前传输时机的功率控制调整值。
本公开实施例中,比例因子也可以被称为调整因子或功控调整因子或其他名字等,比例因子可以用于对TPC命令调整值进行调整以确定功率控制调整值。
如此,本公开实施例中基于比例因子和第二参数值两者来确定当前传输时机的功率控制调整值,更能够适应实际需要的功率调整的幅度,其中比例因子基于间隔长度被确定,考虑了两次功率控制之间的时域跨度,保证了通信性能。
在另一些实施例中,如果终端设备120被配置有传输功率控制TPC累加(tpc-Accumulation)参数,那么在210,终端设备120可以获取间隔长度,其中该间隔长度为时域窗口的起始传输时机至当前传输时机之间的总长度或时域窗口的长度;获取来自接入网设备的DCI中的TPC命令字段参数;基于间隔长度和TPC命令字段参数,确定在当前传输时机的功率控制调整值。
关于间隔长度可以参照上述实施例中的相关描述,为了简洁,这里不再重复。
在一些示例中,TPC命令字段可以占用2比特,相应地,TPC命令字段参数为0至3中任一值。在另一些示例中,TPC命令字段可以占用3比特,相应地,TPC命令字段参数为0至7中任一值。
示例性地,基于间隔长度和TPC命令字段参数确定在当前传输时机的功率控制调整值可以包括:确定与间隔长度和TPC命令字段参数所对应的TPC绝对值,并将该TPC绝对值作为当前传输时机的功率控制调整值。
作为一例,如表3所示,可以基于TPC命令字段参数确定TPC绝对值的行,可以基于间隔长度确定TPC绝对值的列,从而基于TPC命令字段参数和间隔长度两者能够确定TPC 绝对值。
本公开实施例中,针对不同的间隔长度可以适用不同的TPC绝对值。例如表3中,当间隔长度为3时,对应的TPC绝对值为-8、-2、2、8。当间隔长度为2时,对应的TPC绝对值为-6、-1、1、6。
表3
应注意的是,表3仅是示意性的,TPC绝对值的某一列可以对应一个或多个间隔长度,例如间隔长度为3或4都对应表3的第2列,间隔长度为1或2都对应表3的第3列;或者,TPC绝对值的某一列可以对应间隔长度的区间,例如间隔长度处于区间(2,4]对应表3的第2列,间隔长度处于区间(0,2]对应表3的第3列。或者,TPC绝对值可以包括更多或更少的列。
如此,本公开实施例中基于间隔长度等来确定当前传输时机的功率控制调整值,更能够适应实际需要的功率调整的幅度,考虑了两次功率控制之间的时域跨度,保证了通信性能。并且可选地考虑了对于TPC命令字段的扩展,具备一定的灵活性。
在另一种实现方式中,终端设备120要进行的上行传输是PUCCH,则在210所确定的功率控制调整值是PUCCH功率控制调整值。
为了下文的描述,假设终端设备120在服务小区c的激活上行链路部分带宽(active Uplink Bandwidth Part,active UL BWP)b的载波f上进行PUCCH传输,并将在传输时机i上状态为l的PUCCH功率控制调整值表示为g
b,f,c(i,l)。
具体地,在210,终端设备120可以基于时域窗口的起始传输时机的初始功率控制调整值以及累加来确定在当前传输时机的功率控制调整值,其中累加为在与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加。
具体地,终端设备120可以获取时域窗口的起始传输时机的初始功率控制调整值;确定在与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加;基于初始功率控制调整值以及累加,确定当前传输时机的功率控制调整值。
本公开实施例中,TPC累加参数可以是通过高层信令被配置或提供的,在终端设备120未被提供有TPC累加参数时,可以基于起始传输时机的初始功率控制调整值来确定在当前传输时机的功率控制调整值。
示例性地,可以将时域窗口的起始传输时机的初始功率控制调整值表示为g
b,f,c(i-i
0,l),其可以是在确定起始传输时机的发射功率时所确定的。
示例性地,第一参数值可以是DCI中与TPC命令字段(TPC command field)参数所对应的TPC累加值,具体地为用于PUCCH的TPC累加值。在一些示例中,第一参数值可以是由调度与该PUCCH对应的物理下行链路共享信道(Physical Downlink Shared Channel,PDSCH) 传输的DCI格式中的TPC命令字段所指示的,如下表4所示。在另一些示例中,第一参数值可以是通过循环冗余校验(Cyclic Redundancy Check,CRC)由传输功率控制-物理上行共享信道-无线网络临时标识(TPC-PUSCH-RNTI)加扰的DCI格式2_2所指示的。

示例性地,可以将用于PUCCH的第一参数值表示为δ
PUCCH,b,f,c(m,l),进而将与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加表示为
表示集合C
i中的TPC累加值的总和,其中,集合C
i是基于第一时刻和第二时刻所确定的。
与起始传输时机关联的第一时刻可以是起始传输时机的前第S11个符号。也就是说,第一时刻位于起始传输时机之前,且第一时刻与起始传输时机可以间隔有S11个符号。换句话说,第一时刻位于起始传输时机之前的第S11个符号。例如第一时刻可以是起始传输时机i-i
0的第前K
PUCCH(i-i
0)-1个符号,即S11=K
PUCCH(i-i
0)-1。
与当前传输时机关联的第二时刻可以是当前传输时机的前第S12个符号。也就是说,第二时刻位于当前传输时机之前,且第二时刻与当前传输时机可以间隔有S12个符号。换句话说,第二时刻位于当前传输时机之前的第S12个符号。例如第二时刻可以是当前传输时机i的第前K
PUCCH(i)个符号,即S12=K
PUCCH(i)。
可理解,i

在一些示例中,可以通过下面的方式来确定K
PUCCH(i)。如果该PUCCH传输是响应于检测到的DCI格式,那么K
PUCCH(i)是该DCI对应的PDCCH的最后一个符号到对应的PUCCH传输的第一个符号之间的符号数。
在另一些示例中,可以通过下面的方式来确定K
PUCCH(i)。如果该PUCCH传输不是响应于检测到的DCI格式,那么K
PUCCH(i)是K
PUCCH,min个符号数,其可以等于每个时隙的符号数

可理解,确定K
PUCCH(i-i
0)-1的方式与确定K
PUCCH(i)的方式是类似的,因此这里不再重复。
本公开实施例中,第一参数值的累加是第一时刻与第二时刻之间的所有的第一参数值的累加。该累加可以一次确定,也可以针对每个传输时机分别确定后再累加。该过程与上面结合图6和图7部分针对PUSCH的描述类似的,为了简洁,这里不再重复。
如此,可以得到在与起始传输时机关联的第一时刻至与当前传输时机关联的第二时刻之间接收到的所有DCI中的第一参数值的累加。进一步地,本公开实施例中,可以基于初始功率控制调整值f
b,f,c(i-i

那么g
b,f,c(i,l)=g
b,f,c(i-i
0,l)。否则,将初始功率控制调整值与第一参数值的累加之和作为当前传输时机的功率控制调整值,表示为:
如此,本公开实施例中,在确定当前传输时机的功率控制调整值时,能够真实反映TPC命令对功控的调整,不会因联合信道估计对功率的限制而遗漏TPC累加的传输功率控制命令值,更能够适应实际的调整幅度,保证了通信性能。
在220,终端设备120基于在当前传输时机的功率控制调整值,确定在当前传输时机的发射功率。
在一种实现方式中,终端设备120要进行的上行传输是PUSCH,在210所确定的功率控制调整值是PUSCH功率控制调整值,那么相应地,在220,可以确定PUSCH发射功率。
示例性地,如果终端设备120在服务小区c的激活上行链路部分带宽(active Uplink Bandwidth Part,active UL BWP)b的载波f上进行PUSCH传输,使用索引为j的参数集配置,对于状态为l的PUSCH功率控制调整值f

在另一种实现方式中,终端设备120要进行的上行传输是PUCCH,在210所确定的功率控制调整值是PUCCH功率控制调整值,那么相应地,在220,可以确定PUCCH发射功率。
示例性地,如果终端设备120在服务小区c的激活上行链路部分带宽(active Uplink Bandwidth Part,active UL BWP)b的载波f上进行PUCCH传输,使用索引为q
u的参数集配置,对于状态为l的PUCCH功率控制调整值g

在230,终端设备120在当前传输时机以发射功率进行传输。
具体地,终端设备120可以以P

d,l)传输PUSCH,或者,以P
PUCCH,b,f,c(i,q
u,q
d,l)传输PUCCH。
如此,本公开实施例中在确定当前传输时机的发射功率时,能够考虑在该当前传输时机之前的时域窗口,使得功率状态调整状态能够更加匹配时机需要调整的值,确保通信性能。
可理解,本公开实施例中的时域窗口可以用于联合信道估计,并且联合信道估计不限于 一次调度的PUSCH重复之间或者一次调度的PUCCH重复之间,联合信道估计可以是不同次调度的PUSCH重复之间,或者可以是不同次调度的PUCCH重复之间,或者可以是PUSCH与PUCCH之间,或者可以是随机接入场景中的消息3重复(Msg3repetition)之间,等等,本公开对此不限定。尽管上面分别针对PUSCH和PUCCH描述了实施例,但是本公开还可以包括上述所列的实施例的任意组合,另外还可以包括针对其他上行传输的发射功率,等等,本公开中不再一一罗列。
可理解,尽管上述实施例针对“时域窗口”进行了描述,该时域窗口也可以被称为联合传输时机(JTO)、用于联合信道估计的传输时机(transmission occasion for joint channel estimation,TOJ)等。例如,针对PUSCH重复类型A的场景或针对PUCCH重复的场景,联合传输时机对应于覆盖多个TO的时域窗口。例如,针对PUSCH重复类型B的场景而言,联合传输时机对应于实际重复,而非名义重复。
相应地,针对“联合传输时机(JTO)”确定PUSCH功率控制调整值的过程可以包括:在未被配置有TPC累加参数时,基于上一联合传输时机的初始PUSCH功率控制调整值以及累加确定当前联合传输时机的PUSCH功率控制调整值,其中该累加为从与上一联合传输时机关联的第一时刻至与当前联合传输时机关联的第二时刻之间的DCI中第一PUSCH参数值的累加。类似地,针对“联合传输时机(JTO)”确定PUCCH功率控制调整值的过程可以包括:基于上一联合传输时机的初始PUCCH功率控制调整值以及累加确定当前联合传输时机的PUCCH功率控制调整值,其中该累加为从与上一联合传输时机关联的第一时刻至与当前联合传输时机关联的第二时刻之间的DCI中第一PUCCH参数值的累加。
可理解的是,针对“联合传输时机(JTO)”确定功率控制调整值时,其中的累加可以是一次完成的或者也可以是按照TO多次完成的,不管如何确定累加,在联合传输时机进行功控的方式可以参照已有的方式。如此仅通过将现有的TO替换为JTO便可以确定符合实际需求的功率控制调整值,简化了处理方式的同时,保证了通信性能。
图8示出了根据本公开实施例的传输方法800的另一个示意流程图。作为示例,方法800可以实现在图1所示的终端设备120处。为了便于理解,以下以终端设备120为例对传输方法800进行描述,但这仅仅是示例性的,无意对本公开的实施例进行任何限制。
方法800开始于框810。在810,终端设备120获取功率指示信息,其中功率指示信息用于指示在当前时域资源的功率调整值,该功率指示信息包括TPC指示信息,该当前时域资源包括至少两个传输时机或者该当前时域资源的前一个时域资源包括至少两个传输时机。
在820,终端设备120基于功率指示信息,确定在当前时域资源的功率控制调整值。
在830,终端设备120基于在当前时域资源的功率控制调整值,确定在当前时域资源的发射功率。
在840,终端设备120在当前时域资源以该发射功率进行传输。
示例性地,包括至少两个传输时机的时域资源可以用于联合信道估计,或者可以用于其他场景等,本公开对此不限定。示例性地,时域资源可以是时域窗口,或者也可以称为时间窗口、联合传输时机(JTO)、不变传输时机、用于联合信道估计的传输时机(TOJ)或其他等。示例性地,功率控制调整值也可以被称为功率控制调整状态或功率控制调整状态值或者功率控制调整状态参数或者功率控制调整状态项或功率控制调整参数或其他等,本公开对此不限定。
本公开实施例中,当前时域资源内的至少两个传输时机可以具有相同发送特征信息,其中相同发送特征信息包括以下中的至少一项:相同的TPMI、相同的发射功率、相同的频域资源占用、相位连续性、相同的天线端口等。类似地,前一个时域资源内的至少两个传输时机可以具有相同发送特征信息。
举例来说,当前时域资源内的至少两个传输时机具有相同的发射功率意味着:在当前时域资源的非起始传输时机不进行功率控制/功率调整。或者可以理解为,在当前时域资源的第一个传输时机进行功率控制/功率调整,在第一个传输时机之后的其他传输时机的发射功率等于第一个传输时机的发射功率。
在一种实现方式中,图8所示的方法800可以用于确定终端设备120的PUSCH发射功率。示例性地,在未被配置有TPC累加参数的情况下,在820,基于当前时域资源的前一个时域资源的初始功率控制调整值以及累加,确定在当前时域资源的PUSCH功率控制调整值,其中所述累加为在与前一个时域资源关联的第一时刻至与当前时域资源关联的第二时刻之间接收到的所有DCI中的功率指示信息所指示的功率调整值的累加。
TPC指示信息指示的功率调整值可以是从取值集合中所确定的。作为一个示例,该取值集合可以是TPC累加值,具体的,为PUSCH的TPC累加值。举例来说,TPC指示信息可以是TPC命令字段参数,功率指示信息所指示的功率调整值可以是与TPC命令字段参数对应的PUSCH的TPC累加值。关于该实施例可以参照上述结合表1等进行的描述,为了简洁,这里不再赘述。
在另一种实现方式中,图8所示的方法800可以用于确定终端设备120的PUSCH发射功率。示例性地,在未被配置有TPC累加参数的情况下,在820,基于当前时域资源的前一个传输时机的初始PUSCH功率控制调整值以及PUSCH累加,确定在当前时域资源的PUSCH功率控制调整值,其中所述累加为在与前一个传输时机关联的第一时刻至与当前时域资源关联的第二时刻之间接收到的所有DCI中的功率指示信息所指示的功率调整值的PUSCH累加。
关于第一时刻和第二时刻可以参照上面的实施例中关于第一时刻和第二时刻的相关描述,为了简洁,这里不再重复。
TPC指示信息指示的功率调整值可以是从第一取值集合中所确定的。作为一个示例,TPC指示信息可以是TPC命令字段参数,功率指示信息所指示的功率调整值可以是与TPC命令字段参数对应的PUSCH的TPC累加值。
在该实现方式的一些示例中,该第一取值集合中的元素至少有一个大于3,和/或,该第一取值集合中的元素至少有一个小于-1。
在该实现方式的一些示例中,该第一取值集合中的元素的数量可以等于4个,或者可以大于4个。举例来说,TPC指示信息可以为TPC命令字段参数,TPC命令字段占用的比特数可以大于2,例如3,从而TPC命令字段参数可以为0至7中的值,相应地第一取值集合中也可以包含8个元素,其中至少一个大于3或者至少一个小于-1。
在一些示例中,该第一取值集合是RRC配置的或者是预定义的。
在另一些示例中,该第一取值集合是从至少两个第一集合中确定的。举例来说,可以基于RRC信令中的第一集合指示信息从至少两个第一集合中确定第一取值集合。作为一例,该第一集合指示信息可以为索引。举例来说,可以基于预定义的准则从至少两个第一集合中确定第一取值集合。预定义的准则可以是用于联合信道估计的场景等。作为一例,预定义的准 则可以是间隔长度。该间隔长度为前一个时域资源的长度或者为前一个时域资源的第一个传输时机至当前时域资源的第一个传输时机之间的长度。
可选地,至少两个第一集合可以是预定义的,例如通过各种方式预先配置或预先存储的。在另一些示例中,至少两个第一集合中的部分或全部可以是通过RRC信令配置的。在另一些示例中,至少两个第一集合中的部分或全部可以是通过DCI进行指示的。本公开实施例中,至少两个第一集合也可以通过其他的方式进行配置等,这里不再罗列。
可选地,至少两个第一集合中的元素的部分或全部可以是预定义的,或者可以是通过RRC信令配置的。
如此,本公开实施例中实现了对于PUSCH的TPC累加值的扩展,使得功率控制调整值的范围更大,调整量更加精细,更能适应诸如联合信道估计等实际场景所需的功控调整幅度,保证了通信性能。
在另一种实现方式中,图8所示的方法800可以用于确定终端设备120的PUCCH发射功率。示例性地,在820,基于当前时域资源的前一个时域资源的初始功率控制调整值以及累加,确定在当前时域资源的PUCCH功率控制调整值,其中所述累加为在与前一个时域资源关联的第一时刻至与当前时域资源关联的第二时刻之间接收到的所有DCI中的功率指示信息所指示的功率调整值的累加。
TPC指示信息指示的功率调整值可以是从取值集合中所确定的。作为一个示例,该取值集合可以是TPC累加值,具体的,为PUCCH的TPC累加值。举例来说,TPC指示信息可以是TPC命令字段参数,TPC指示信息指示的功率调整值可以是与TPC命令字段参数对应的PUCCH的TPC累加值。关于该实施例可以参照上述结合表4等进行的描述,为了简洁,这里不再赘述。
在另一种实现方式中,图8所示的方法800可以用于确定终端设备120的PUCCH发射功率。示例性地,在820,基于当前时域资源的前一个传输时机的初始PUCCH功率控制调整值以及PUCCH累加,确定在当前时域资源的PUCCH功率控制调整值,其中所述累加为在与前一个传输时机关联的第一时刻至与当前时域资源关联的第二时刻之间接收到的所有DCI中的功率指示信息所指示的功率调整值的PUCCH累加。
关于第一时刻和第二时刻可以参照上面的实施例中关于第一时刻和第二时刻的相关描述,为了简洁,这里不再重复。
TPC指示信息指示的功率调整值可以是从第二取值集合中所确定的。作为一个示例,TPC指示信息可以是TPC命令字段参数,功率指示信息所指示的功率调整值可以是与TPC命令字段参数对应的PUCCH的TPC累加值。
在该实现方式的一些示例中,该第二取值集合中的元素至少有一个大于3,和/或,该第二取值集合中的元素至少有一个小于-1。
在该实现方式的一些示例中,该第二取值集合中的元素的数量可以等于4个,或者可以大于4个。举例来说,TPC指示信息可以为TPC命令字段参数,TPC命令字段占用的比特数可以大于2,例如3,从而TPC命令字段参数可以为0至7中的值,相应地第二取值集合中也可以包含8个元素,其中至少一个大于3或者至少一个小于-1。
在一些示例中,该第二取值集合是RRC配置的或者是预定义的。
在另一些示例中,该第二取值集合是从至少两个第二集合中确定的。举例来说,可以基 于RRC信令中的第二集合指示信息从至少两个第二集合中确定第二取值集合。作为一例,该第二集合指示信息可以为索引。举例来说,可以基于预定义的准则从至少两个第二集合中确定第二取值集合。预定义的准则可以是用于联合信道估计的场景等。作为一例,预定义的准则可以是间隔长度。该间隔长度为前一个时域资源的长度或者为前一个时域资源的第一个传输时机至当前时域资源的第一个传输时机之间的长度。
可选地,至少两个第二集合可以是预定义的,例如通过各种方式预先配置或预先存储的。在另一些示例中,至少两个第二集合中的部分或全部可以是通过RRC信令配置的。在另一些示例中,至少两个第二集合中的部分或全部可以是通过DCI进行指示的。本公开实施例中,至少两个第二集合也可以通过其他的方式进行配置等,这里不再罗列。
可选地,至少两个第二集合中的元素的部分或全部可以是预定义的,或者可以是通过RRC信令配置的。
如此,本公开实施例中实现了对于PUCCH的TPC累加值的扩展,使得功率控制调整值的范围更大,调整量更加精细,更能适应诸如联合信道估计等实际场景所需的功控调整幅度,保证了通信性能。
可理解的是,在一些实施例中,当前时域资源包括至少两个传输时机,前一个时域资源可以包括一个或多个传输时机。以时域资源为时域窗口为例,在一例中,如图3,当前时域资源(如时域窗口320)包括4个传输时机,且前一个时域资源(如时域窗口310)包括4个传输时机。在另一例中,如图5,当前时域资源(如时域窗口513)包括4个传输时机,且前一个时域资源(如时域窗口512)包括1个传输时机。
可理解的是,在另一些实施例中,当前传输资源包括一个传输时机,例如,当前传输资源是用于联合信道估计的单独的传输时机,或者当前传输资源不是用于联合信道估计的单独的传输时机,前一个时域资源包括至少两个传输时机。在一例中,如图5,假设当前时域资源是时域窗口512,其包括一个传输时机。前一个时域资源是时域窗口511,其包括两个传输时机。
在另一种实现方式中,图8所示的方法800可以用于确定终端设备120的PUSCH发射功率。示例性地,在配置有TPC累加参数的情况下,在820,基于比例因子和TPC指示信息指示的功率调整值,确定在当前时域资源的功率控制调整值。
在一些示例中,比例因子可以是预先配置的或者预先定义的。也就是说,比例因子是预定值,这样能够直接获取预定义的比例因子来确定功率控制调整值,效率高,降低了终端设备的计算复杂度。
在另一些示例中,可以基于第三消息来确定比例因子,其中第三消息可以被承载于RRC信令中。
举例来说,第三消息可以包括一个比例因子,如此,终端设备120可以直接从第三消息获取比例因子,该方式快速高效,效率高,降低了终端设备的计算复杂度。
在另一些示例中,可以基于第三消息和第四消息来确定比例因子,其中第三消息可以被承载于RRC信令中且该第三消息包括多个比例因子,其中第四消息可以是DCI或媒体接入控制-控制元素(Medium Access Control-Control Element,MAC-CE)。该第四消息用于确定多个比例因子中的其中一个。
具体地,终端设备120可以接收第三消息,该第三消息包括多个比例因子。终端设备 120可以接收第四消息,该第四消息包括比例因子指示信息。终端设备120进一步从多个比例因子中获取比例因子指示信息所指示的比例因子。这样能够基于第三消息和第四消息两者来确定比例因子,这样能够通过RRC半静态地进行配置,并由DCI或MAC-CE进行指示,能够避免DCI或MAC-CE的信令开销过大,并且该方式能够更快速地实现对比例因子的更新,更加灵活。
在另一些示例中,可以基于预定义的准则来确定比例因子。举例来讲,预定义的准则为间隔长度,该间隔长度为前一个时域资源的长度或者为前一个时域资源的第一个传输时机至当前时域资源的第一个传输时机之间的长度。
在一例中,可以将间隔长度作为比例因子,例如将间隔长度去量纲之后的无量纲值作为比例因子。
在另一例中,可以基于间隔长度与比例因子的对应关系,获取与该间隔长度对应的比例因子,其中该对应关系是由接入网设备的RRC所配置的或预定义的。
在又一例中,可以基于间隔长度以及预定义的缩放因子,确定比例因子。例如,将间隔长度与缩放因子的乘积作为比例因子。
可理解,本公开实施例中的长度可以以下至少一项:时隙数、符号数、传输时机数、重复数等,其中重复数可以是名义重复数或实际重复数等,本公开对此不限定。
在另一些示例中,可以基于第三消息和预定义的准则来确定比例因子。第三消息被承载于RRC信令中,预定义的准则为间隔长度,该间隔长度为前一个时域资源的长度或者为前一个时域资源的第一个传输时机至当前时域资源的第一个传输时机之间的长度。
举例来讲,第三消息包括缩放因子,那么可以将间隔长度与缩放因子的乘积作为比例因子。
在另一些示例中,可以基于第四消息和预定义的准则来确定比例因子。第四消息为DCI,预定义的准则为间隔长度,该间隔长度为前一个时域资源的长度或者为前一个时域资源的第一个传输时机至当前时域资源的第一个传输时机之间的长度。
举例来讲,第四消息包括缩放因子,那么可以将间隔长度与缩放因子的乘积作为比例因子。
在另一些示例中,可以基于第三消息、第四消息和预定义的准则来确定比例因子。第三消息被承载于RRC信令中,第四消息为DCI或AMC-CE,预定义的准则为间隔长度。
举例来讲,第三消息包括多个缩放因子,第四消息包括缩放因子指示信息,那么可以从多个缩放因子中获取该缩放因子指示信息所指示的缩放因子,进而可以将间隔长度与缩放因子的乘积作为比例因子。
本公开实施例中,比例因子也可以被称为调整因子或功控调整因子或其他名字等,比例因子可以用于对TPC命令调整值进行调整以确定功率控制调整值。
在一些实施例中,TPC指示信息指示的功率调整值可以是从取值集合中确定的。
可选地,该取值集合或取值集合中的元素可以是预定义的。
在一例中,TPC指示信息可以为TPC命令字段参数,TPC指示信息指示的功率调整值可以是与TPC命令字段参数对应的TPC绝对值。如上面的表2所示,TPC指示信息指示的功率调整值可以是从取值集合{-4,-1,1,4}中确定的。
在另一例中,TPC指示信息指示的功率调整值所在的取值集合中,至少一个元素的值大 于4。例如,该取值集合可以是{-6,-1,1,6}或{-8,-2,2,8}或其他等。
在另一例中,TPC指示信息指示的功率调整值所在的取值集合中,所包含的元素的数量大于4。举例来说,TPC指示信息可以为TPC命令字段参数,TPC命令字段占用的比特数可以大于2,例如3,从而TPC命令字段参数可以为0至7中的值,相应地取值集合中也可以包含8个元素,其中至少一个大于4。例如,该取值集合可以是{-6,-4,-2,-1,1,2,4,6}或其他等。
在一些实施例中,该取值集合或取值集合中的元素是由RRC配置的,从而终端设备120能够基于TPC指示信息从该取值集合中确定所指示的功率调整值。
在一些实施例中,该取值集合可以是从至少两个取值集合(下面简称为至少两个集合)中确定的。
在一例中,可以基于RRC信令中的集合指示信息从至少两个集合中确定取值集合。
举例来讲,集合指示信息可以为索引。至少两个集合可以具有对应的索引,不同的集合具有不同的索引。那么可以基于RRC信令中的索引确定对应的取值集合。以表5为例,关于用于JCE的TPC绝对值存在两个集合,分别为{-6,-1,1,6}和{-8,-2,2,8}。假设集合{-6,-1,1,6}的索引为A1,集合{-8,-2,2,8}的索引为A2。那么,如果RRC信令中的索引是A1,则可以确定取值集合为{-6,-1,1,6}。如果RRC信令中的索引是A2,则可以确定取值集合为{-8,-2,2,8}。可理解,集合指示信息也可以为其他的形式,这里不再罗列。
表5
在另一例中,可以基于预定义的准则从至少两个集合中确定取值集合。预定义的准则可以是用于联合信道估计的场景等。
以表5为例,与TPC命令字段对应的有两个集合,分别为:TPC绝对值和用于JCE的TPC绝对值。那么在确定用于联合信道估计的当前时域资源的发射功率时,可以确定取值集合为用于JCE的TPC绝对值所在的列,即取值集合是{-6,-1,1,6}。
在又一例中,可以基于预定准则从至少两个集合中确定取值集合。预定义的准则可以是间隔长度。该间隔长度为前一个时域资源的长度或者为前一个时域资源的第一个传输时机至当前时域资源的第一个传输时机之间的长度。
以表6为例,与TPC命令字段对应的有两个集合,分别为:间隔长度=3的用于JCE的TPC绝对值和间隔长度=2的用于JCE的TPC绝对值。那么,终端设备120可以首先确定间隔长度,进而可以基于间隔长度确定取值集合。
表6
如此,通过对TPC命令字段在行和/或列方向上进行扩展,能够适应实际需要的功率调整幅度,保证了通信性能。具体的,将TPC绝对值进行扩充,其不仅与TPC命令字段有关,还与间隔长度有关,这样的扩充使得功率控制调整值的范围更大,调整量更加精细,更能适应实际场景所需的功控调整幅度,保证了通信性能。
应注意的是,表6仅是示意性的,用于JCE的TPC绝对值的某一列可以对应一个或多个间隔长度,例如间隔长度为3或4都对应表6的第2列,间隔长度为1或2都对应表6的第3列;或者,用于JCE的TPC绝对值的某一列可以对应间隔长度的区间,例如间隔长度处于区间(2,4]对应表6的第2列,间隔长度处于区间(0,2]对应表6的第3列。或者,用于JCE的TPC绝对值可以包括更多或更少的列。
另外,可理解,也可以通过其他的方式从至少两个集合中确定取值集合,这里不再一一罗列。
在一些示例中,至少两个集合可以是预定义的,例如通过各种方式预先配置或预先存储的。在另一些示例中,至少两个集合中的部分或全部可以是通过RRC信令配置的。在另一些示例中,至少两个集合中的部分或全部可以是通过DCI进行指示的。本公开实施例中,至少两个集合也可以通过其他的方式进行配置等,这里不再罗列。
在一些实施例中,820确定在当前时域资源的功率控制调整值,可以包括:确定当前时域资源的每个传输时机的功率控制调整值。
在一些实施例中,820确定在当前时域资源的功率控制调整值,可以包括:确定当前时域资源的第一个传输时机的功率控制调整值。可选地,对于当前传输资源的其他传输时机(即不是第一个传输时机)可以通过其他的规则进行确定,例如其他的规则为:其他传输时机的发射功率等于第一个传输时机的发射功率。
关于图8中的框830和框840,可以参见上述图2的实施例中220和230中的相关描述,为了简洁,这里不再重复。
如此,本公开实施例中基于功率指示信息(如TPC命令指示信息)来确定当前时域资 源的功率控制调整值,简化了终端设备的处理过程,降低了终端设备处的复杂性,提高了确定发射功率的效率。并且,与TPC命令指示信息对应的功率调整值(如用于JCE的TPC绝对值)可以具有更大的值或更大的范围,如此能够适应实际需要的功率调整的幅度,确保了通信性能。
图9示出了根据本公开实施例的传输方法900的又一个示意流程图。作为示例,方法900可以实现在图1所示的接入网设备110处。为了便于理解,以下以接入网设备110为例对传输方法900进行描述,但这仅仅是示例性的,无意对本公开的实施例进行任何限制。
方法900开始于框910。在910,接入网设备110向终端设备120发送功率指示信息,其中功率指示信息用于指示当前时域资源的功率调整值,该功率指示信息包括TPC指示信息,该当前时域资源包括至少两个传输时机或者该当前时域资源的前一个时域资源包括至少两个传输时机。
在920,接入网设备110在当前时域资源接收终端设备120以发射功率进行的传输,该TPC指示信息为确定该发射功率的基础。
示例性地,时域资源可以用于联合信道估计,或者可以用于其他场景等,本公开对此不限定。示例性地,时域资源可以是时域窗口,或者也可以称为时间窗口、联合传输时机(JTO)、不变传输时机、用于联合信道估计的传输时机(TOJ)或其他等。
示例性地,功率指示信息可以用于终端设备120基于该功率指示信息确定功率控制调整值,并进一步基于功率控制调整值来确定发射功率,其中功率控制调整值也可以被称为功率控制调整状态或功率控制调整状态值或者功率控制调整状态参数或者功率控制调整状态项或功率控制调整参数或其他等,本公开对此不限定。
本公开实施例中,当前时域资源内的至少两个传输时机可以具有相同发送特征信息,其中相同发送特征信息包括以下中的至少一项:相同的TPMI、相同的发射功率、相同的频域资源占用、相位连续性、相同的天线端口等。
举例来说,当前时域资源内的至少两个传输时机具有相同的发射功率意味着:在当前时域资源的非起始传输时机不进行功率控制/功率调整。或者可以理解为,在当前时域资源的第一个传输时机进行功率控制/功率调整,在第一个传输时机之后的其他传输时机的发射功率等于第一个传输时机的发射功率。
可选地,当前时域资源的前一个时域资源可以包括一个或多个传输时机,前一个时域资源可以是用于联合信道估计的时域窗口,或者可以是用于非联合信道估计的传输时机。
在一些实施例中,其中TPC指示信息占用的比特数大于2或者等于2。作为一例,该TPC指示信息可以为TPC命令字段参数。
示例性地,TPC指示信息指示的功率调整值可以是传输功率控制命令值,例如TPC累加值、TPC绝对值等。
在一些实施例中,其中TPC指示信息指示的功率调整值是从取值集合中确定的,该取值集合包括至少一个大于4的值。作为一例,该取值集合或取值集合中的元素可以是由接入网设备110通过RRC信令进行配置的。作为一例,该取值集合中的元素数量可以等于4个,或者该取值集合中的元素数量大于4个。
在一些实施例中,该方法900还可以包括:接入网设备110向终端设备120发送第三消息,该第三消息用于终端设备120确定发射功率,其中该第三消息被承载于RRC信令中,该第三消息包括比例因子或缩放因子。
在一例中,第三消息包括比例因子,从而终端设备120能够基于该比例因子以及TPC指示信息指示的功率调整值来确定功率控制调整值。
在另一例中,第三消息包括缩放因子,从而终端设备120能够基于该缩放因子和预定义的准则(如间隔长度,如结合图8的实施例所述)确定比例因子,进而基于该比例因子以及TPC指示信息指示的功率调整值来确定功率控制调整值。
在一些实施例中,该方法900还可以包括:接入网设备110向终端设备120发送第三消息,该第三消息包括多个比例因子;接入网设备110还向终端设备120发送第四消息,该第四消息用于从多个比例因子中确定其中之一,其中该第三消息被承载于RRC信令中,该第四消息为DCI或MAC-CE,该第三消息和第四消息用于终端设备120确定发射功率。
在一些实施例中,该方法900还可以包括:接入网设备110向终端设备120发送配置信息,其中该配置信息用于配置多个取值集合(下面简称为多个集合)。如此,终端设备120能够从多个集合中确定取值集合,进一步地终端设备120可以基于TPC指示信息从取值集合中确定TPC指示信息指示的功率调整值。
在一些实施例中,该方法900还可以包括:接入网设备110向终端设备120发送集合指示信息,该集合指示信息用于终端设备120从多个集合中确定该取值集合。
在一例中,该集合指示信息可以为索引或索引值,从而终端设备120能够基于该索引或索引值从多个集合中确定取值集合,进一步地终端设备120可以基于TPC指示信息从取值集合中确定TPC指示信息指示的功率调整值。
可理解的是,关于比例因子、缩放因子、取值集合、多个集合等的相关描述可以参照上面的实施例,为了简洁,这里不再重复。
如此,本公开实施例中接入网设备能够通过半静态或静态的方式进行配置或指示,这样能够更快速地更新或调整比例因子等,该配置方式更加灵活。
