Description
本申请涉及无线通信技术领域,尤其涉及无线通信系统中的信息发送方法、信息接收方法及通信装置。
5G通信系统致力于支持更高系统性能,将支持多种业务类型、不同部署场景和更宽的频谱范围。其中,上述的多种业务类型包括增强移动宽带(enhanced mobile broadband,eMBB),海量机器类型通信(massive machine type communication,mMTC),超可靠低延迟通信(ultra-reliable and low latency communications,URLLC),多媒体广播多播业务(multimedia broadcast multicast service,MBMS)和定位业务等。不同部署场景包括室内热点(indoor hotspot)、密集城区(dense urban)、郊区、城区宏覆盖(urban macro)及高铁场景等。更宽的频谱范围是指5G将支持高达100GHz的频谱范围,这既包括6GHz以下的低频部分,也包括6GHz以上最高到100GHz的高频部分。
如果不同优先级业务的上行控制信息(uplink control information,UCI)需要通过独立编码的方式在同一个物理上行共享信道上(physical uplink shared channel,PUSCH)进行复用时,在对不同优先级UCI依次进行资源映射的情况下,可能会导致译码错误的问题。例如,如果高优先级的UCI发生映射错误导致低优先级UCI映射位置也发生错误,这将导致网络设备对UCI信息译码错误。因此,如何提高UCI信息的译码准确性是亟待解决的问题。

下面将结合附图,对本申请中的技术方案进行描述。可以理解的是,所描述的实施例是本申请一部分的实施例,而不是全部的实施例。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(wideband code division multiple access,WCDMA)系统、通用分组无线业务(general packet radio service,GPRS)、长期演进(Long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、第五代(5th generation,5G)系统或新无线(new radio,NR)、或者未来演进网络等。
为便于理解本申请实施例,首先结合图1详细说明适用于本申请实施例提供的方法的通信系统。图1中示出了适用于本申请实施例提供的方法的通信系统的示意图。如图所示,该通信系统可以包括至少一个网络设备,如图1中所示的5G系统中的基站(gNB);该通信系统还可以包括至少一个终端设备,如图1中所示的用户设备(user equipment,UE)1至UE 6。网络设备与终端设备之间可以通过无线链路通信。例如,网络设备可以向终端设备发送配置信息,终端设备可以基于该配置信息向网络设备发送上行数据;又例如,网络设备可以向终端设备发送下行数据。因此,图1中的gNB和UE可以构成一个通信系统。
该通信系统中的终端设备,如,UE 4至UE 6,也可以构成一个通信系统。例如,UE4可以控制UE 5和UE 6执行相应的指令。本申请对此不作限定。
应理解,该通信系统中的网络设备可以是任意一种具有无线收发功能的设备。该网络设备包括但不限于:演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(baseband Unit,BBU),无线保真(wireless fidelity,WiFi)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为5G,如,NR,系统中的gNB,或,传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络 节点,如基带单元(BBU),或,分布式单元(distributed unit,DU)等。
在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括射频单元(radio unit,RU)。CU实现gNB的部分功能,DU实现gNB的部分功能,比如,CU实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能,DU实现无线链路控制(radio link control,RLC)、媒体接入控制(media access control,MAC)和物理(physical,PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令,也可以认为是由DU发送的,或者,由DU+CU发送的。可以理解的是,网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外,CU可以划分为接入网(radio access network,RAN)中的网络设备,也可以将CU划分为核心网(core network,CN)中的网络设备,本申请对此不做限定。
还应理解,该无线通信系统中的终端设备也可以称为用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
还可以理解,图1仅为便于理解而示例的简化示意图,该通信系统中还可以包括其他网络设备或者还可以包括其他终端设备,图1中未予以画出。
5G通信系统相比与4G通信系统的一大特征就是增加了对超可靠低时延业务URLLC的支持。URLLC的业务种类包括很多种,典型的用例包括工业控制、工业生产流程自动化、人机交互和远程医疗等。
由于URLLC业务具有低时延和高可靠性的特征,因此相比于5G通信中的其他业务,URLLC为高优先级业务。所谓URLLC业务的低时延和高可靠性的性能,根据3GPP RAN和RAN 1工作组对URLLC业务的性能指标定义可知。
时延是指用户应用层数据包从发送端无线协议栈层2/3的SDU(Service Data Unit)到达接收端无线协议栈层2/3SDU所需的传输时间。在网络设备和终端设备均不不处于非连续接收态时,URLLC业务的用户面时延要求对于上下行均为0.5ms,其中0.5ms的性能要求是指数据包的平均时延。
可靠性是指发送端在一定时间内(L秒)向接收端正确传输X比特数据的成功概率,上述的时间仍定义为用户应用层数据包从发送端无线协议栈层2/3SDU到达接收端无线协议栈层2/3SDU所需的时间。对于URLLC业务,一个典型需求是在1ms内发送32bytes数据达到99.999%的可靠性,对于具体的URLLC业务有不同的要求,例如某些极端苛刻的工业控制需要在端到端时延在0.25ms内达到99.9999999%的传输成功概率。
由于URLLC业务需要具备高可靠性的特征,混合自动重传(hybrid automatic repeat request,HARQ)是一种高效的传输机制,通过HARQ可以极大提高下行数据传输的可靠性。UE会根据实际情况发送HARQ反馈信息(HARQ-ACK),当UE向网络设备发送HARQ否定应答消息时,网络设备才需要重传,这样降低了数据传输的整体资源消耗。
HARQ反馈信息属于上行控制信息UCI的一种,UCI还包括调度请求(scheduling request,SR),信道状态信息(channel state information,CSI)由CSI part 1和CSI part 2组成。
现有技术中对相同优先级下的不同类型的UCI信息和上行数据信息复用在物理上行共享信道(physical uplink shared channel,PUSCH)上传输时的映射规则如下,下面将结合图2对相同优先级UCI和上行数据复用在PUSCH上进行说明,其中,图2是本申请一种现有技术中相同优先级UCI和上行数据复用在PUSCH上映射规则示意图,图3本申请另一种现有技术中相同优先级UCI和上行数据复用在PUSCH上映射规则示意图。
以相同优先级的不同类型UCI包括HARQ反馈信息、CSI part1和CSI part2为例,相同优先级UCI和上行数据信息复用在PUSCH上的映射顺序为HARQ反馈信息、CSI part1、CSI part2和上行数据信息。
图2中的(a)、(b)、(c)和(d)的HARQ反馈信息映射为当HARQ反馈信息是大于2比特时,那么按照实际的大小,在DMRS符号之后的第一个可用符号开始,顺序进行映射。如果HARQ反馈信息可以占满当前整个符号,则占满当前符号,再占据下一个符号。如果HARQ反馈信息不足以占满当前整个符号,则会在当前符号上,等间隔分散在频域资源上。
S201,映射UCI信息中的HARQ反馈信息,HARQ反馈信息从DMRS符号之后的第一个可用符号开始映射,如图2的(a)。
S202,当HARQ反馈信息是大于2比特时,如图2的(b),从PUSCH上的第一个可用符号资源开始顺序映射CSI part 1,其中,第一个可用符号资源为除去DMRS、HARQ反馈信息映射的资源单元,PUSCH上第一个可用符号资源。
S203,当HARQ反馈信息是大于2比特时,如图2的(c),从PUSCH上的第一个可用符号资源开始顺序映射CSI part 2,其中,第一个可用符号资源为除去DMRS、HARQ反馈信息以及CSI part 1映射的资源单元,PUSCH上第一个可用符号资源。
S204,当HARQ反馈信息是大于2比特时,如图2的(d),从PUSCH上的第一个可用符号资源开始顺序映射上行数据,其中,第一个可用符号资源为除去DMRS、HARQ反馈信息、CSI part 1以及CSI part 2映射的资源,PUSCH上第一个可用符号资源。
图3中的(a)、(b)、(c)、(d)和(e)的HARQ反馈信息映射为当HARQ反馈信息为0、1或者2比特中任意一种大小时,在PUSCH中的DMRS符号之后的第一个UCI可用符号开始,按照2比特的HARQ反馈信息预留PUSCH资源,成为预留区域。应理解,由于资源块中每个符号代表的比特数取决于选用的调制阶数,因此,图中UCI和上行数据映射资源单元的数目仅为示例作用。
S301,预留UCI信息中的HARQ反馈信息需要映射的资源单元数目,形成HARQ反馈信息的资源预留区域,该资源预留区域从DMRS符号之后的第一个可用符号开始,如图3的(a)所示。
S302,映射UCI信息中的CSI part 1,当HARQ反馈信息为0、1或者2比特中任意 一种大小时,如图3的(b),从PUSCH上的第一个可用符号资源开始顺序映射CSI part1,绕开HARQ反馈信息预留区域,保证CSI part 1不会与HARQ反馈信息冲突。其中第一个可用符号资源为除去DMRS、HARQ反馈信息预留区域的资源单元,PUSCH上第一个可用符号资源。
S303,映射UCI信息中的CSI part 2,当HARQ反馈信息为0、1或者2比特中任意一种大小时,如图3的(c),从PUSCH上的第一个可用符号资源开始顺序映射CSI part2,此时不需要绕开HARQ反馈信息预留区域,其中第一个可用符号资源为除去DMRS、CSI part 1的资源单元,PUSCH上第一个可用符号资源。
S304,映射上行数据信息,当HARQ反馈信息为0、1或者2比特中任意一种大小时,如图3的(d),从PUSCH上的第一个可用符号资源开始顺序映射上行数据,此时不需要绕开HARQ反馈信息预留区域,其中第一个可用符号资源为除去DMRS、CSI part 1以及CSI part 2映射的资源单元,PUSCH上第一个可用符号资源。
S305,当HARQ反馈信息为0、1或者2比特中任意一种大小时,如图3的(e),不论S303和S304中是否将HARQ反馈信息资源预留区域填满,HARQ反馈信息资源预留区域将被HARQ反馈信息重新映射,映射位置从HARQ反馈信息资源预留区域第一个符号开始以覆盖掉已经映射在该预留区域的信息。
除了相同优先级不同UCI和上行数据复用在同一个PUSCH资源块上以外,还可能是优先级不同的UCI复用在同一个PUSCH上,在一些特定场景下,不同优先级业务发生时域冲突时,例如高优先级HARQ反馈信息和低优先级HARQ反馈信息发生时域冲突时,可以通过对二者的联合编码后统一进行资源映射来实现在同一个PUSCH上的复用,还可以通过对二者的独立编码后依次进行资源映射来实现同一个PUSCH上的复用。
网络设备在物理下行控制信道(physical downlink control channel,PDCCH)或者物理下行共享信道(physical downlink shared channel,PDSCH)上向终端设备发送高低优先级业务的下行控制信息(downlink control information,DCI)后,终端设备在PUSCH上向网络设备发送UCI信息来对终端设备处理高低优先级的业务情况进行信息反馈。
当终端设备对高优先级DCI信息进行盲检时,可能会存在漏检的情况。在同一个上行信道资源块上复用高优先级UCI和低优先级UCI时,针对二者为独立编码后依次进行映射的情况,终端设备在PUSCH上先映射高优先级UCI信息,再映射低优先级UCI信息。
当终端设备在由用于上行发送的下行控制信息格式0-1(UL DCI format 0-1)调度的PUSCH上发送高低优先级的UCI时,由于存在用于上行的下行分配指示(downlink assignment index,UL DAI)的指示字段,该指示字段用于指示本次需要反馈HARQ的DL DCI的总数,即使终端设备对高优先级的DCI信息盲检时存在漏检的情况,终端设备也会将漏检的DL DCI对应的UCI信息补上,从而不影响低优先级UCI信息在PUSCH上的位置,以此避免网络设备发生译码错误。
但是,当网络设备在配置(configured grant,CG)的PUSCH和用于UL DCI format 0-0调度的PUSCH上发送高低优先级的UCI时,由于不存在UL DAI指示字段,所以,当终端设备对高优先级的DCI信息盲检存在漏检情况时,终端设备发送的UCI信息将会缺少漏检的高优先级DCI信息对应的UCI信息,该UCI的载荷大小(payload size)发生错误,使得低优先级UCI信息位置发生错误,使得网络设备出现译码错误。
为了解决上述问题,本申请实施例提出了一种信息发送方法、信息接收方法及通信装置,下面将结合附图对此进行详细说明。
应理解,本申请实施例中第一UCI表示较高优先级业务的UCI,第二UCI表示较低优先级业务的UCI,其中,第一UCI的优先级比第二UCI的优先级高。
本申请实施例中对不同业务之间存在相对优先级,第一业务优先级高于第二业务优先级,例如,URLLC业务相对于eMBB业务具有较高的优先级,在本申请实施中不作限制。
第一UCI和第二UCI发送组合可以是以下四种,本申请实施例对此不作限制。
第一种,第一UCI为高优先级HARQ反馈信息和第二UCI为低优先级HARQ反馈信息。
第二种,第一UCI为高优先级HARQ反馈信息和第二UCI为低优先级除HARQ反馈信息以外的其他类型UCI信息,例如,低优先级CSI信息,在本申请实施例中不作限制。
第三种,第一UCI为高优先级CSI信息和第二UCI为低优先级HARQ反馈信息。
第四种,第一UCI为高优先级CSI信息和第二UCI为低优先级除HARQ反馈信息以外的其他类型UCI信息,例如,低优先级CSI信息,在本申请实施例中不作限制。
图4是本申请实施例一种信息发送方法和信息接收方法流程示意图。
S401,终端设备确定第一上行控制信息UCI在PUSCH上映射的起始位置和资源单元数目上限。
应理解,第一UCI资源单元数目上限表示第一UCI在该PUSCH上最多能够映射的资源单元数目。
S402,根据该第一UCI在PUSCH上映射的起始位置和资源单元数目上限,确定第二UCI在PUSCH上映射的起始位置,其中该第一UCI的优先级高于该第二UCI的优先级。
S403,确定该第一UCI的实际资源单元数和该第二UCI的实际资源单元数。
应理解,第一UCI实际资源单元数为第一UCI映射在PUSCH上的实际资源单元数,该实际资源单元数小于等于第一UCI资源单元数目上限,第二UCI实际资源单元数的本质和第一UCI实际资源单元数一致,在此不作赘述。
应理解,实际资源单元数可以根据速率匹配规则确定,第一UCI和第二UCI根据各自的业务类型,分别有不同的速率匹配规则。
S404,根据该第一UCI在PUSCH上映射的起始位置和第一UCI实际资源单元数在PUSCH上映射第一UCI,根据该第二UCI在PUSCH上映射的起始位置和第二UCI实际资源单元数在PUSCH上映射第二UCI。
S405,端设备发送该PUSCH。
S406,在S401之前,网络设备给终端设备发送配置信息,该配置信息可以用于确定第一UCI映射在PUSCH上的资源单元数目的上限。
下面将结合图5具体说明本申请实施例中信息发送方法和信息接收方法,图5是本申请实施例一种不同优先级UCI复用在PUSCH上的方法流程示意图。
S501,确定PUSCH数据传输参数。
应理解,PUSCH数据传输参数用于确定第一UCI和第二UCI映射在PUSCH上的起始位置、资源单元数目上限以及实际资源单元数,上行信道数据传输参数可以包括PUSCH资源单元总数、解调参考信号(demodulation reference signal,DMRS)位置和资源单元数 目、相位跟踪参考信号(phase tracking reference signal,PTRS)的位置和资源单元数目,调制阶数Q
m和码率R等。
其中PUSCH可以传输UCI信息和上行数据信息,还可以传输UCI信息但不传输上行数据信息,在本申请实施例中不作限制。
PUSCH资源单元总数可以通过网络设备高层配置信息进行配置或者通过网络设备给终端设备发送DCI进行动态指示,在本申请实施例中不作限制。
应理解,第一UCI和第二UCI占据的实际资源数将使用PUSCH上可用于传输UCI信息的资源单元总数来确定,其中,PUSCH上可用于传输UCI信息的资源单元总数可以为除DMRS资源单元数目和PTRS资源单元数目以外的资源单元数目,在本申请实施例中不作限制。
应理解,DMRS信息的位置将用于确定第一UCI映射在PUSCH上的起始位置,第一UCI信息中包括HARQ反馈信息时,HARQ反馈信息在PUSCH上的起始位置位于DMRS位置之后。
例如,如图6所示,图6为本申请实施例中的一种PUSCH时频资源,横向为时域信息,横向时域最小单位为一个符号,纵向为频域信息,纵向频域最小单位为一个子载波,由一个符号和一个子载波共同组成时频资源的最小单位,资源单元(resource element,RE)。如图所示,DMRS映射在PUSCH第三个符号上,因此,如果第一UCI包括HARQ反馈信息时,则HARQ反馈信息从第四个符号开始映射。
应理解,除HARQ反馈信息以外的UCI信息从第一个符号开始映射。
应理解,当终端设备在PUSCH上传输UCI信息,但不传输上行数据信息时,调制阶数Q
m和码率R将用于确定UCI信息映射在PUSCH上的实际资源数。
S502,终端设备根据网络设备发送的配置信息,确定第一UCI资源单元数目上限和第二UCI资源单元数目上限。
对应于图4中的S401步骤中的确定第一UCI资源单元数目上限。
应理解,网络设备在无线资源控制信令(radio resource control,RRC)上向终端设备发送配置信息。

LP。同样可以通过上述方式得到第一UCI资源单元数目上限比例和第二UCI资源单元数目上限比例,在此不作赘述。
通过第一UCI资源单元数目上限比例和PUSCH上可用于传输UCI的资源单元总数的乘法运算,得到第一UCI资源单元数目上限;通过第二UCI资源单元数目上限比例和PUSCH上可用于传输UCI的资源单元总数的乘法运算,得到第二UCI资源单元数目上限。
第一UCI资源单元数目上限可以用于确定第二UCI映射在PUSCH上的起始位置,还可以用于控制第一UCI实际资源单元数目不超过第一UCI资源单元数目上限。
第二UCI资源单元数目上限用于控制第二UCI实际资源单元数目不超过第二UCI资源单元数目上限。
S503,确定第二UCI在PUSCH上的起始位置。
可选的,根据第一UCI映射在PUSCH上的起始位置和资源单元数目上限,确定第二UCI在PUSCH上的起始位置,这个步骤对应于图4中的S402,根据该第一UCI占据的PUSCH的上限,确定第二上行控制信息UCI占据的PUSCH的起始位置,其中该第一UCI的优先级高于该第二UCI的优先级。
第二UCI映射在PUSCH上的起始位置可以位于第一UCI在PUSCH上映射第一UCI资源单元数目上限之后的第N个完整的符号的第一个资源单元,其中N为大于等于1的正整数。
例如,图7为本申请实施例中一种第二UCI在PUSCH中起始位置示意图。图7的(a)以UCI信息包括HARQ反馈信息为例,第一UCI映射在PUSCH上的起始位置为DMRS信息之后的符号,根据第一UCI的资源单元数目上限为第一UCI在PUSCH上预留资源,该预留资源为图7中虚框范围内的数值,也就是第一UCI的资源单元数目上限,预留了图示时频资源块中的第四个符号至第六个符号。即使第一UCI预留在PUSCH上的资源单元数目上限未占满第六个符号,第二UCI映射在PUSCH上的起始位置可以位于第七个符号第一个资源单元。
图7的(b)以UCI信息不包括HARQ反馈信息为例,第一UCI资源单元数目的上限为图7中虚框范围内的数值,第一UCI除了可以从DMRS信息之后的符号开始预留资源,还可以根据第一UCI的资源单元数目上限从PUSCH第一个符号开始为第一UCI预留资源。即使第一UCI预留在PUSCH上的资源单元数目上限未占满第四个符号,第二UCI 映射在PUSCH上的起始位置可以位于第五个符号第一个资源单元。
根据第一UCI映射在PUSCH上的起始位置和资源单元数目上限,确定第二UCI映射在PUSCH上的起始位置,由于第二UCI映射在PUSCH上的起始位置不受第一UCI是否发生载荷大小错误限制,因此这种映射方式可以保证在第一UCI发生载荷大小错误时,第二UCI映射在PUSCH上的位置正确,避免第二UCI映射位置发生连带错误。
可选的,第二UCI映射在PUSCH上的起始位置位于PUSCH上最后一个符号。
例如,如图8所示,图8是本申请实施例中另一种第二UCI在PUSCH中的起始位置示意图。第二UCI映射在PUSCH上的起始位置位于该PUSCH上最后一个符号,按照先频后时的映射规则,即先频域映射再时域映射,第二UCI在PUSCH最后一个符号的映射顺序有两种。
如图8的(a)所示,第二UCI可以从最后一个符号的第一个资源单元开始映射,按照资源单元频域索引从小到大的顺序映射,映射完最后一个符号,按照资源单元时域索引从大到小的顺序映射。
如图8的(b)所示,第二UCI还可以从最后一个符号的最后一个资源单元开始映射,按照资源单元频域索引从大到小的顺序映射,映射完最后一个符号,按照资源单元时域索引从大到小的顺序映射。
S504,根据网络设备发送的配置信息,通过速率匹配规则确定第一UCI实际资源单元数和第二UCI实际资源单元数。
应理解,第一UCI实际资源单元数为第一UCI映射在PUSCH上的实际资源单元数,该实际资源单元数小于等于第一UCI资源单元数目上限,第二UCI实际资源单元数的本质和第一UCI实际资源单元数一致,在此不作赘述。
其中,第一UCI实际资源单元数和第二UCI实际资源单元数通过各自对应的速率匹配规则获得。
PUSCH上可以既传输UCI信息又传输上行数据信息,PUSCH上还可以传输UCI信息,但不传输上行数据信息。
当PUSCH上既传输UCI信息又传输上行数据信息时,不同类型UCI分别按照以下速率匹配规则计算映射在PUSCH上的实际资源数。
其中,公式(1)第一部分的物理意义是根据HARQ反馈信息实际的数据比特数(编码前的比特数O
ACK和CRC校验比特数L
ACK)、码率偏移因子
和数据上行数据的码率,来计算HARQ反馈信息编码后的资源单元数。
其中(O
ACK+L
ACK)/Q'
ACK的物理意义是UCI的码率,
的物理 意义是上行数据的码率,
表示上行数据码率和UCI码率的比值,UCI的码率小于上行数据的码率,在传输性能上有利于UCI的可靠性。
公式(1)第二部分的物理意义是根据UCI映射在PUSCH上的资源单元数目上限比例α,来确定HARQ反馈信息资源单元数目上限,其中
为PUSCH的上可用于传输UCI的资源单元总数,其中l
0为第一个解调参考信号DMRS的符号之后不承载所述DMRS的第一个符号的符号索引。
两部分的最小值作为HARQ反馈信息实际资源单元数Q'
ACK。
CSI信息由CSI part 1和CSI part 2组成,CSI part 1的实际资源单元数目由公式(2)计算得到,CSI part 2实际资源单元数目由公式(3)计算得到。
当UCI信息仅包括HARQ反馈信息时,HARQ反馈信息的实际资源单元数目由公式(1)计算得到。
当PUSCH上传输UCI信息但不传输上行数据信息时,不同类型UCI分别按照以下速率匹配规则计算实际资源单元数。
当UCI信息包括HARQ反馈信息和CSI信息时,HARQ反馈信息的实际资源单元数由公式(4)计算得到。
其中,Q
m为调制阶数,R为码率。
CSI信息由CSI part 1和CSI part 2组成,当PUSCH上传输UCI信息,但不传输上行数据信息时,若确定有CSI part 2,则CSI part 1的实际资源单元数由公式(5)计算得到,此时CSI part 2的实际资源单元数由公式(6)计算得到。若确定没有CSI part 2,则CSI part 1的实际资源单元数由公式(7)计算得到.
本申请实施例,在S502中终端设备确定了第一UCI资源单元数目的上限可以为上限比例α
HP和第二UCI资源单元数目上限可以为上限比例α

当PUSCH上传输UCI信息,但不传输上行数据信息时,选择公式(5)至(7)来计算第一UCI的实际资源单元数目。

当PUSCH上传输UCI信息,但不传输上行数据信息时,选择公式(5)至(7)来计算第二UCI的实际资源单元数目。
根据S502中直接或者间接获得的第一UCI资源单元数目的上限和第二UCI资源单元数目上限,确定第一UCI实际资源单元数和第二UCI实际资源单元数。
以第一UCI为高优先级HARQ反馈信息和第二UCI为低优先级HARQ反馈信息为例。

现有技术中不同优先级的上限比例仅用来控制UCI映射在PUSCH上的实际资源单元数不超过UCI在PUSCH上的资源单元数目上限,在本申请实施例中,上限比例不仅具有该作用,还用来辅助确定第一UCI映射在PUSCH上的资源单元数目的上限以确定第二UCI在PUSCH上开始映射的位置,从而保证第一UCI在编码过程中发生映射错误时,不影响网络设备对第二UCI的译码。
S505,根据第一UCI和第二UCI映射在PUSCH上的起始位置和实际资源单元数在PUSCH上进行资源映射。
