Description

信息传输的方法和通信装置

技术领域
本申请涉及通信领域,更为具体的,涉及一种信息传输的方法和通信装置。
背景技术
在多站点协作传输中,一个终端设备可以同时接收多个网络设备的数据。终端设备可以利用混合自动重传(hybrid automatic repeat request,HARQ)机制来向多个网络设备反馈对数据的接收情况。具体的,终端设备可能需要在一个时间单元内向多个网络设备反馈接收到的数据的肯定应答(acknowledgement,ACK)/否定应答(negative acknowledgement,NACK)信息。同时,终端设备还需要在该时间单元内向多个网络设备反馈信道状态信息(channel state information,CSI)。这样,就存在在同一个时间单元内多个CSI和多个HARQ的复用传输(multiplexing)问题。目前,CSI和HARQ之间的关联关系或者复用规则需要通过高层信令配置。而且CSI被丢弃的概率很大,无法保证CSI的正常传输。因此,在CSI和HARQ复用时如何保证CSI的正常传输成为目前急需解决的问题。

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
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、未来的第五代(5th Generation,5G)系统或新无线(New Radio,NR)等。
本申请实施例中的终端设备可以指用户设备、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。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备,该网络设备可以是全球移动通讯(Global System of Mobile communication,GSM)系统或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional NodeB,eNB或eNodeB),还可以是云无线接入网络(Cloud Radio Access Network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等,本申请实施例并不限定。
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的定义的长期演进LTE/增强长期演进(LTE-advanced,LTE-A)/NR系统中,下行链路的多址接入方式通常采用正交频分复用多址接入(orthogonal frequency division multiple access,OFDMA)方式。下行资源从时间(时域)上看被划分成了多个正交频分复用多址(orthogonal frequency division multiple,OFDM)符号,从频率(频域)上看被划分成了多个子载波。下行链路中的部分时频资源用于承载物理下行链路控制信道(physical downlink control channel,PDCCH)。PDCCH用于承载下行链路控制信息(downlink control information,DCI)。DCI是物理层(Physical Layer)中网络设备指示用户设备(user equipment,UE)行为的控制信息。同时,高层信令也可以用于网络设备指示UE行为。高层信令是高于物理层的用于控制和管理相关UE的指示信息,例如,无线资源控制(radio resource control,RRC)信令等。下行链路中的部分时频资源用于承载物理下行链路共享信道(physical downlink shared channel,PDSCH)。PDSCH用于承载用户设备和网络设备进行交互的数据,对于所有接入到网络系统中的用户设备而言,PDSCH是共享的。
在网络设备进行数据传输之前,网络设备需要通过用于下行调度的DCI通知终端设备在特定的时频资源上以特定的接收方式接收数据。在终端设备进行数据传输之前,需要网络设备通DCI通知终端设设备在特定的时频资源上以特定的发送方式发送数据。DCI的信息比特通过输送至信道编码模块并完成速率匹配,之后按照特定的准则(例如正交相移键控(quadrature phase shift keying,QPSK))进行控制信息比特的调制,最终映射到时频域资源上形成PDCCH。网络设备需要通过用于上行调度的DCI通知终端设备在特定的时频资源上以特定的发送方式发送数据。
PDCCH所占的时频资源通常通过高层信令配置或者通过系统消息配置,在配置的过程中,是以控制资源集合(control-resource set,CORESET)为配置单位的。网络设备指 示给终端设备的DCI的信息比特(用于调度终端设备接收PDSCH/发送PUSCH)均承载在PDCCH上,或者可以理解为DCI的信息比特承载于PDCCH所占的时频资源上。CORESET可以理解为:在系统中的时频资源上采用某些特定的时频资源承载DCI信令,这些特定的时频资源会预先通过高层信令通知给终端设备,使得终端设备可以在后续特定的检测时刻中均在该特定的时频资源上检测DCI信令。控制资源集合包括用于网络设备发送PDCCH的所占的时频资源信息,网络设备可以为终端设备配置一个或者多个控制资源集合,网络设备可以在终端设备对应的任意一个控制资源集合上,向终端设备发送PDCCH。
一个控制资源集合在频域上包含
Figure PCTCN2020078407-appb-000001
个RB,包含的RB数和位置通过高层信令配置。控制资源集合的频域资源配置方式是通过以6个RB为粒度的位图(bitmap)指示,通常情况下,一个CORESET是在一段系统带宽内指示的。同时,CORESET在时域上的定义通常在一个slot内包含
Figure PCTCN2020078407-appb-000002
个OFDM符号,
Figure PCTCN2020078407-appb-000003
的取值可以为1,2,3。一个CORESET所包含的OFDM符号数和位置通过高层信令配置。例如,对于时隙(slot)级别的调度而言,CORESET通常处于一个slot的前3个OFDM符号上,对于非时隙(non-slot)级别(调度的时域资源小于一个slot)的调度而言,CORESET可以处于一个slot内的任意位置。一个终端设备可以被配置多个CORESET,每一个CORESET可以配置索引号(索引值)。其中,CORESET索引值0通常用于承载系统消息。CORESET索引的配置信息也由系统消息或者高层信令通知,其他的CORESET通常用于承载小区公共的DCI(用于指示小区公用的控制消息)或者终端设备特定的DCI(例如用于调度单一传播(unicast)的PDSCH/PUSCH)。每一个CORESET可能由一个服务小区内的多个终端设备共享(由网络设备实现相应的调度)。这些共享的终端设备可以在该CORESET指示的时频资源上接收网络设备发送的PDCCH,并根据PDCCH向网络设备发送数据或者接收网络设备发送的数据。
终端设备通过混合自动重传请求(hybrid automatic repeat request,HARQ)的反馈机制通知基站下行数据是否正确接收。终端设备反馈下行数据对应的HARQ的肯定应答(acknowledgement,ACK)/否定应答(negative acknowledgement,NACK)信息,比如,若终端正确解调下行数据,则该下行数据对应的ACK信息通过PUCCH反馈给基站,若终端未正确解调下行数据,则该下行数据对应的NACK信息通过PUCCH反馈给基站,从而使得基站可以进行重传调度。目前,终端设备在一个时间单元内使用物理上行控制信道(physical uplink control channel,PUCCH)资源来反馈ACK/NACK。具体的,PUCCH上会承载每个PDSCH/每个传输块(transport block,TB)对应的ACK/NACK信令,每个TB对应一个ACK/NACK比特,用来指示该TB是否被正确接收,若ACK/NACK比特位为0,表示NACK,即相应TB未正确接收。若ACK/NACK比特位为1,表示ACK,即相应TB正确接收。根据HARQ码字(codebook),终端设备会确定多个PDSCH/TB的ACK/NACK比特可能共同承载于同一个PUCCH上,比如,不同时刻的多个DCI调度的PDSCH分别对应的HARQ反馈位于同一个时隙slot内,则多个HARQ反馈比特会合并形成一个比特位图(bitmap)承载于同一个PUCCH上。
PUCCH资源除了用于承载HARQ之外,还可以承载终端设备反馈信道状态信息(Channel State Information,CSI),网络设备会配置至少一个CSI上报配置集合,该配置 集合中可以包括:CSI参考信号(CSI reference signal,CSI-RS)资源配置信息、CSI测量和上报方法、CSI上报内容以及CSI上报采用的PUCCH资源。通常,承载于PUCCH上的CSI是周期的或者半静态的,即配置一个CSI上报周期,终端设备会周期性在相应的PUCCH资源上传输CSI。
PUCCH资源还可以承载终端设备发送的调度请求(Scheduling request,SR),网络设备可以根据SR为该终端设备分配传输资源。
终端设备可以通过上行控制信息(uplink control information,UCI)承载CSI、HARQ以及SR中的一个或者多个,即终端设备可以将CSI、HARQ以及SR中的多个进行联合编码形成UCI,并将UCI发送给网络设备。
目前,网络设备通过无线资源控制(radio resource control,RRC)信令为终端设备配置最多4个PUCCH资源集(PUCCH resource set),每个PUCCH resource set包括多个PUCCH resource。每个PUCCH resource set的配置参数可以包括:PUCCH resource set ID、最大的UCI比特数、以及PUCCH resource列表(list)。
如果终端设备传输O UCI个UCI比特,且UCI中包括HARQ-ACK比特,终端设备会确定当前发送UCI的时隙(slot)采用的PUCCH resource set。具体的,每个PUCCH resource set中均会配置相应的UCI比特值区间,终端设备根据当前时刻实际上报的UCI比特数确定采用哪一个PUCCH resource set:
对于pucch-ResourceSetId=0,UCI比特值区间为O UCI≤2,其中包括1个或者2个HARQ-ACK比特,和一个与HARQ-ACK比特同时传输的SR请求(SR为0或者1比特)。
对于pucch-ResourceSetId=1,UCI比特值区间为2<O UCI≤N 2,其中N 2是配置在PUCCH resource set1中的最大UCI比特数。
对于pucch-ResourceSetId=2,UCI比特值区间为N 2<O UCI≤N 3,其中N 3是配置在PUCCH resource set2中的最大UCI比特数。
对于pucch-ResourceSetId=3,UCI比特值区间为N 3<O UCI≤1706。
每个PUCCH resource的配置参数可以包括:PUCCH resource ID、PUCCH resource格式(format)以及PUCCH resource。
DCI中存在3比特的指示信息用于指示终端设备选择RRC信令中配置的多个PUCCH resource中的一个PUCCH resource承载该DCI调度的数据的反馈信息。
目前,在一段特定带宽内(比如一个载波内),终端设备不期望同时发送多个PUCCH,如果多个PUCCH resource在时域上重叠(overlap),则会定义多个PUCCH资源之间的复用(multiplexing)准则或者丢弃(dropping)准则。
例如:当多个承载CSI的PUCCH资源在一个slot内的时域上overlap时,会按照预先协定的模式将该多个CSI合并形成一个CSI承载于一个PUCCH上,合并方式如:将多个CSI依次顺序编码。如果对于每一个CSI配置了一个用于承载该CSI的PUCCH资源,对相应overlap的CSI按照优先级排序,仅传输优先级最高的CSI。如果每个CSI配置了多个用于承载该CSI的PUCCH资源,根据该CSI的比特数从配置的多个PUCCH资源中确定一个PUCCH资源传输,确定的方式:确定多个CSI的总比特数,若没有PUCCH资源能承载,则丢弃其中优先级较低的CSI后重新确定总比特数,直到存在一个PUCCH资源恰好能承载为止。
进一步的,对于承载CSI的PUCCH资源、承载HARQ的PUCCH资源、承载SR的PUCCH资源在同一个时隙内时域上overlap时,RU对于CSI、HARQ以及SR在一个时隙内的传输时也需要考虑复用的问题。具体的,可以根据下述的公式确定UCI的比特数以及相应的PUCCH资源。
终端设备根据最近一次DCI中指示的PUCCH资源,并基于UCI比特数确定使用的PUCCH resource set。

根据上述的公式,对于CSI、HARQ以及SR在一个时隙内的复用传输时,可以确定传输该UCI(包括HARQ-ACK、SR和CSI)的PUCCH资源集,并根据DCI指示的PUCCH资源确定从确定的PUCCH资源集中确定PUCCH资源,并在该PUCCH资源上传输该UCI的PUCCH资源。如果该PUCCH资源所能承载的比特数小于该UCI的比特数,则按照CSI的优先级丢弃CSI,直至该PUCCH资源可以承载该UCI为止。
在下行传输中,终端设备可以同时与多个网络设备进行通信,即一个终端设备可以同时接收多个网络设备的数据,该传输模式被称为多站点协作传输(coordinated multiple points transmission/reception,CoMP)。多个网络设备组成一个协作集与该终端设备同时 进行通信,协作集内的网络设备可以各自连接不同的控制节点,各个控制节点之间进行信息交互,例如,各个控制节点交互调度策略信息以达成协作传输的目的。或者,协作集内的网络设备均连接同一个控制节点,该控制节点接收协作集内的多个网络设备收集的终端设备上报的状态信息(例如信道状态信息(channel state information,CSI)或者参考信号接收功率(reference signal received power,RSRP),并根据协作集内所有终端设备的状态信息对协作集内的终端设备进行统一调度,再将调度策略交互给与终端设备连接的网络设备,再由各个网络设备通过PDCCH承载的DCI信令分别通知各自的终端设备。根据协作集内多个网络设备的对某个终端设备的数据传输策略划分,CoMP传输模式包括以下三种类型:
第一种:动态传输节点切换(dynamic point switching,DPS)模式:对于某一个终端设备而言,与该终端设备进行数据传输的网络设备在不同的传输时刻动态切换,以尽量选择协作集内当前信道条件较好的网络设备与该终端设备之间进行数据的传输。即多个网络设备分时与某个终端设备传输数据。
第二种:相干传输(coherent joint transmission,C-JT)模式:多个网络设备同时与某个终端设备传输数据,且多个网络设备的天线进行联合预编码。即选择最优预编码矩阵进行多个网络设备的天线之间的联合相位和幅度加权。相干传输机制需要多个网络设备的天线进行精确的相位校准使得多组天线之间进行精确的相位加权。
第三种:非相干传输(non-coherent joint transmission,NC-JT)模式:多个网络设备同时与某个终端设备进行传输数据,且多个网络设备的天线进行独立预编码。即每个网络设备独立选择最优预编码矩阵进行该网络设备天线之间的联合相位和幅度加权,非相干传输机制不要求多个网络设备的天线进行精确的相位校准。
根据协作集内网络设备之间的信息交互时延的大小,CoMP传输的场景可以分为理想回传(ideal backhaul)场景和非理想回传(non-ideal backhaul)场景。
下面将简单介绍理想回传(ideal backhaul)场景和非理想回传(non-ideal backhaul)场景。
对于理想回传(ideal backhaul)场景,由于网络设备之间或者网络设备到控制节点之间的站间距较近,或者依靠传输损耗较小的光纤连接,网络设备之间的交互时延可以忽略不计。在这种情况下,网络设备之间的交互为动态的实时的交互的过程。通常可以假设的协作机制为:协作集内的网络设备存在一个中心调度节点(控制节点)用于对多个网络设备内的所有终端设备进行联合资源调度。网络设备负责接收终端设备反馈的CSI和调度请求等信息并通过回传(backhaul)给中心调度节点,中心调度节点收集协作集内网络设备的反馈完成调度并将调度策略回传给网络设备,由协作集内的服务网络设备(例如为服务传输接收点(serving transmission reception point,Serving TRP))下发控制信息DCI给终端设备。根据调度策略,该终端设备的数据由Serving TRP下发,或者由Serving TRP和协作网络设备(例如为协作传输接收点(coordinate transmission reception point,coordinate TRP)联合下发(协作传输)。
对于理想回传(ideal backhaul)场景,可以采用1个DCI的方式进行数据调度指示。如图1所示,图1示出了理想回传场景下利用1个DCI的方式进行数据调度的示意图。假设TRP1作为服务TRP(即服务基站),TRP1负责下发DCI1给终端设备,该DCI1用 于通知发给该终端设备的数据所占的时频资源以及发送方式。TRP2为协作TRP,该终端设备的数据由TRP1和TRP2联合下发。TRP1下发的数据为PDSCH1,TRP2下发的数据为PDSCH2。其中,发送方式包含传输数据采用的传输层数、每个码字(codeword)的调制编码方式和接收波束指示信息等。一个码字对应特定的一个或者多个传输层,每个码字对应独立的调制编码方式,并可以动态指示启用和不启用。例如,图1所示的例子中,两个TRP各自采用1层传输下行数据,TRP1发送的DCI1中会启用两个码字,每个码字均对应1个特定的传输层(标准中以不同的端口对应不同的传输层体现)以及1个特定的接收波束指示。即一个码子可以对应一个TRP。图9示出了理想回传场景下另一例利用1个DCI的方式进行数据调度的示意图。如图9所示,TRP1采用2层传输下行数据,则DCI1中会启用一个码字,该码字对应TRP1采用的2个特定的传输层以及接收波束指示。应理解,不同码字可以由同一个TRP发送(单TRP传输模式),也可以由不同TRP发送。也就是说每个码字可以对应一个TRP(CoMP传输模式)。图2所示的为单TRP传输模式。
对于理想回传(ideal backhaul)场景,也可以采用2个DCI的方式进行数据调度指示。图3示出了理想回传场景下利用2个DCI的方式进行数据调度的示意图。如图3所示,2个DCI(DCI1和DCI2)可以分别由两个TRP发送,也可以由同一个TRP发送。每个DCI对应一个码字的时频资源分配指示和发送方式指示,即每个DCI对应一个TRP。在这种情况下,要求终端设备同时检测2个DCI,并根据检测并译码得到的2个DCI,同时接收两个TRP发送的PDSCH。相比于仅采用1个DCI调度2个PDSCH而言,采用2个DCI调度2个PDSCH可以在不增加DCI比特长度的前提下,提高调度的灵活度。
对于非理想回传(non-ideal backhaul)场景,由于网络设备(以TRP为例)间的交互时延会带来性能的损失,网络设备之间的交互时延不可以忽略不计。所以该场景下通常会采用两个TRP各自下发1个DCI分别进行数据调度。在这种情况下,两个TRP之间或者两个TRP与控制节点之间仅需半静态交互调度信息。每个DCI至少可以独立指示资源分配信息以及相应码字的调制编码方式和对应的传输层。图4示出了非理想回传场景下利用2个DCI的方式进行数据调度的示意图。如图4所示,TRP1向终端设备发送DCI1,用于调度PDSCH1的传输。TRP2向终端设备发送DCI2用于调度PDSCH2的传输。每个DCI对应一个码字。应理解,若终端设备在某一个检测周期(例如一个slot)内只检测到一个DCI时,则当前传输为单TRP传输,若终端设备在某一个检测周期(例如一个slot)内检测到两个DCI时,则当前传输为多TRP传输。
应该注意的是,对于上述的理想回传(ideal backhaul)场景和非理想回传(non-ideal backhaul)场景中的一个DCI或者多个DCI,均指的是在某一个时间段内(比如一个slot,或者终端设备的一个DCI检测周期内)的终端设备特定的用于调度下行数据的DCI。同时,这些DCI所调度的数据可能占用相同的或者部分相同的时频资源,则这些DCI被认为是处于协作传输模式下的指示方式。目前,NR中支持两种用于调度下行数据的DCI,一种为紧凑的DCI格式,只包含调度数据必须的字段,另一种为普通的DCI格式,包含较多的调度数据的字段,普通DCI格式的长度通常大于紧凑DCI格式的长度。除了用于调度下行数据的DCI之外,网络设备还可以下发公共搜索空间集合(common search space,CSS)。具体地,在DCI检测周期内,终端设备可以检测用于调度下行数据的一个DCI或者多个DCI,同时,还可以检测用于指示系统消息、参考信号(reference signal,RS) 触发信息、帧结构指示信息等公共DCI。网络设备在配置终端设备的检测行为时,会在搜索空间的配置参数中配置多个DCI格式,终端设备根据多个DCI格式配置信息进行多次DCI盲检测尝试。
多载波聚合(carrier aggregation,CA)机制中,网络设备在每个载波上也可以发送各自的DCI,从而也需要终端设备也需要具备在某一个检测时间段内同时检测多个DCI的检测能力。
例如,以非理想回传(non-ideal backhaul)场景中2个DCI为例进行说明,
多个(以2个为例)DCI调度的PDSCH对应的HARQ分别反馈给各自的TRP从而避免交互时延。则终端设备需要区分不同时刻的2个DCI,从而确定反馈给各自TRP的HARQ比特数。例如,终端设备在时刻1检测到DCI 1和DCI 2,在时刻2检测到DCI 3和DCI 4,上述DCI1至DCI4均在时刻3反馈。其中,DCI 1和3为TRP 1下发的,DCI 2和4为TRP 2下发的。若期望DCI 1和DCI 3对应的HARQ比特在时刻3联合编码反馈给TRP 1,DCI 2和4对应的HARQ比特在时刻3联合编码反馈给TRP 2,则终端设备需要知道不同时刻的DCI对应同一个TRP。DCI与TRP的对应方法可以有如下三种:
第一种:预先定义不同的CORESET对应不同的TRP。例如,若DCI 1和DCI 3均在CORESET 1中检测到,DCI 2和DCI 4均在CORESET中检测到,则终端设备可以明确DCI 1和DCI 3对应的HARQ反馈给TRP 1,DCI 2和DCI 4对应的HARQ反馈给TRP 2。
第二种:预先将PUCCH资源分组,每个TRP只能指示/配置某一组内的PUCCH resource,例如,DCI 1和DCI 3指示PUCCH资源组1对应TRP 1,DCI 2和DCI 4指示PUCCH资源组2对应TRP 2。终端设备检测到DCI时,便可知该DCI属于哪个TRP发送的。
第三种:DCI中某一个字段指示表征TRP的信息。例如,DCI 1和DCI 3中的该字段指示表征TRP 1,DCI 2和4中的该字段指示表征TRP 2。终端设备检测到DCI时,便可知该DCI属于哪个TRP发送的。
基于此进一步建立承载CSI的PUCCH资源和TRP之间的关联关系。比如,CSI报告设置(reporting setting)与CORESET ID关联,并规定CSI仅与其所关联的CORESET ID对应的DCI的HARQ做multiplexing。终端设备根据该关联关系分别确定每个TRP对应的UCI比特。具体地,基于该TRP对应的HARQ/SR和该TRP对应的CSI的比特数,终端设备可以确定每个TRP对应的CSI和HARQ是否multiplexing、multiplexing后得到的UCI的比特数和发送UCI的PUCCH resource。若HARQ与非关联的CSI发生overlap,则丢弃(drop)该CSI。例如,DCI 1对应HARQ 1,DCI 2对应HARQ 2,若预先配置CSI 2与DCI 1关联,CSI 1与DCI 2关联,则CSI 2和HARQ 1会复用形成UCI 1,CSI 1和HARQ 2会复用形成UCI 2。
目前,CSI和HARQ/DCI之间的关联关系需要通过高层信令配置。例如高层信令配置了多个CORESET之后,将相应的CORESET ID配置给不同的CSI。这种配置方式会增加信令的开销和设计复杂度。同时,这种配置方式会使得CSI被丢弃的概率增加。例如,假设配置的CSI 1和CSI 2均预先与DCI 2相关联,如果在CSI 1和CSI 2反馈的slot内,仅有DCI 1对应的HARQ 1传输,则CSI全部被丢弃,无法保证CSI的正常传输,由于无法保证CSI的正常传输,会降低通信的质量和效率。并且,即使在CSI 1和CSI 2反馈的 slot内,有DCI 2对应的HARQ 2传输,由于HARQ 2的PUCCH资源可能和HARQ 1的PUCCH资源重叠,在HARQ 2和HARQ 1进行multiplexing时,很有可能HARQ 2将被丢弃调,无法保证HARQ 2的传输,则也无法保证CSI的正常传输。
有鉴于此,本申请提供了一种信息传输的方法,多站点协作传输中,通过改变CSI和HARQ之间的关联关系,使得CSI与传输CSI的时间单元内的所有HARQ均关联,即CSI与传输CSI的时间单元内的所有HARQ均可以复用形成UCI。可以保证CSI的正常传输。提高通信效率。
下面结合图5详细说明本申请提供的信息的传输方法,图5是本申请一个实施例的信息的传输方法100的示意性交互图,该方法100可以应用在上述的图1至图4所示的理想回传(ideal backhaul)场景和非理想回传(non-ideal backhaul)场景中,当然也可以应用在其他通信场景中,本申请实施例在此不作限制。
应理解,在本申请实施例中,以终端设备和网络设备作为执行方法100中的各个步骤的执行主体为例,对方法100进行说明。网络设备可以为图5所示的TRP。作为示例而非限定,执行方法100中的各个步骤执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
如图5所示,该方法100包括S110至S130。
S110,终端设备和网络设备确定在第一时间单元内传输的信道状态信息CSI,第一混合自动重传请求HARQ和第二HARQ,该第一HARQ是由第一下行控制信息DCI调度的数据的反馈信息,该第二HARQ是由第二DCI调度的数据的反馈信息。
S120,终端设备和网络设备确定第一上行控制信息UCI和第二UCI,该第一UCI包括该第一HARQ和该CSI,该第二UCI包括该第二HARQ和该CSI。
S130,终端设备向网络设备发送该第一UCI和该第二UCI中的至少一个。
具体而言,在多站点协作传输的场景中,多个网络设备(下文以TRP为例)会向同一个终端设备发送DCI,用于调度各自TRP与终端设备之间的数据等传输。以两个TRP为例说明。两个TRP会分别向终端设备发送DCI,第一TRP向终端设备发送的DCI称为第一DCI,第二终端设备向TRP发送的DCI称为第二DCI。第一DCI用于调度第一TRP向终端设备发送的第一PDSCH,第二DCI用于调度第二TRP向终端设备发送的第二PDSCH。终端设备在收到第一PDSCH和第二PDSCH时,需要通过HARQ机制向第一TRP反馈是否正确接收到第一PDSCH,向第二TRP反馈是否正确接收到第二PDSCH。即终端设备需要向第一TRP反馈是否正确接收到第一PDSCH的ACK/NACK(第一HARQ),终端设备需要向第二TRP反馈是否正确接收到第二PDSCH的ACK/NACK(第二HARQ)。由于终端设备反馈HARQ的时域资源是通过DCI指示的。因此,第一HARQ和第二HARQ可以在一个时间单元(例如同一个时隙)内向第一TRP和第二TRP反馈。并且,在该时间单元内,还可能存在CSI(一个或者多个)需要向第一TRP和第二TRP发送。因此。在步骤S110中,终端设备和网络设备会确定在同一个时间单元传输的CSI和第一HARQ和第二HARQ。其中,第一HARQ和第二HARQ是由不同的TRP发送的PDSCH对应的反馈信息。具体的,第一HARQ是由第一TRP发送的第一DCI调度的数据的反馈信息,第二HARQ是由第二TRP发送的第二DCI调度的数据的反馈信息。
本申请中,第一时间单元的长度可以是一个时隙,或者可以小于或者大于一个时隙。 本申请中,对一个时间单元的长度不做限定。例如,1个时间单元可以是一个或多个子帧;或者,也可以是一个或多个时隙;或者,也可以是一个或多个符号。在本申请的实施例中,符号也称为时域符号,可以是正交频分复用(orthogonal frequency division multiplexing,OFDM)符号,也可以是单载波频分多址(single carrier frequency division multiple access,SC-FDMA)符号,其中SC-FDMA又称为带有转换预编码的正交频分复用(orthogonal frequency division multiplexing with transform precoding,OFDM with TP)。
在S120中。终端设备确定第一UCI和第二UCI。其中,所述第一UCI包括所述第一HARQ和所述CSI,所述第二UCI包括所述第二HARQ和所述CSI。即第一时间单元内的所有CSI分别与第一时间单元内的所有HARQ均进行复用形成多个UCI,每个UCI均包括该CSI。网络设备会确定第一UCI和/或第二UCI。即网络设备可以只确定第一UCI和第二UCI中的一个,或者,网络设备会确定第一UCI和第二UCI。
在S130中,终端设备可以向网络设备发送第一UCI和第二UCI中的至少一个。相应的,网络设备接收该第一UCI和第二UCI中的至少一个。
本申请提供的信息传输的方法,通过改变CSI和HARQ之间的关联关系,使得CSI与传输CSI的时间单元内的所有HARQ均关联,即CSI与传输CSI的时间单元内的所有HARQ均可以复用形成UCI。可以保证CSI的正常传输。提高通信效率。
应理解,本申请实施例中,第一时间单元内的CSI也可以只和第一时间单元内的部分HARQ复用。例如,可以预先定义第一时间单元内的CSI与第一时间单元内的实际发送的HARQ复用。例如,定义CSI与第一HARQ和第二HARQ中的任意一个复用,其中,第一HARQ或者第二HARQ为第一时间单元内实际存在的HARQ,即只要第一时间单元内存在需要反馈的HARQ,CSI就与该HARQ中的任意一个或者多个复用,不限定CSI到底是与第一HARQ和第二HARQ进行复用传输。即CSI可以不用和第一时间单元内的所有HARQ进行复用。
还应理解,在本申请实施例中,第一时间单元内的CSI的个数可以是一个,也可以是多个。即上述的CSI可以是一个CSI,也可以是多个CSI的统称。如果第一时间单元内的CSI的只有一个,则可以将这个CSI分别与多个HARQ分别进行复用形成UCI。例如。如果第一时间单元内有多个CSI,则可以先根据所有CSI的PUCCH资源判断所有CSI的PUCCH资源在时域上是否重叠。如果重叠,则按照CSI的优先级顺序将所有重叠的CSI复用成一个或者多个CSI,然后将复用得到的一个或者多个CSI承载在不重叠的PUCCH上。这样相当于有一个或者多个不重叠的CSI。然后分别将每个不重叠的CSI与第一时间单元内的所有分别HARQ复用。或者,也可以不用判断多个CSI是否重叠,直接将所有的CSI按照优先级顺序和第一时间单元内的所有HARQ复用得到多个UCI。或者,还可以建立CSI与传输DCI的CORESET/CORESET组的关联关系,由于DCI与HARQ之间也具有关联关系,进一步的可以建立CSI与HARQ之间的关联关系,判断与相同的CORESET/CORESET组关联的所有CSI的PUCCH是否重叠,如果重叠,则按照CSI的优先级顺序将重叠的CSI复用成一个CSI,然后在一个PUCCH上承载复用成的一个CSI。然后将这个CSI分别与第一时间单元内的HARQ复用。
还应理解,在第一时间单元内,也可以存在多个不同的TRP对应的HARQ。上述的第一HARQ和第二HARQ并不是限定于两个HARQ。而是为了区分不同的TRP对应的 HARQ。例如,在第一时间单元内还可以存在更多的TRP对应的HARQ。
作为一种具体的实现方式,如图6所示,图6是本申请一些实施例中的信息传输的方法的示意性交互图,在一些实施例中,第一PUCCH用于承载该第一UCI,第二PUCCH用于承载该第二UCI,当该第一PUCCH和该第二PUCCH在时域上重叠时。在图5所示的方法步骤的基础上,该方法100的还包括:
S121,终端设备丢弃第二UCI,或者,只发送第一UCI,其中,该第二UCI占用的符号数少于该第一UCI占用的符号数,或者,该第二UCI包括的肯定应答ACK/否定应答NACK比特数少于该第一UCI包括的ACK/NACK比特数,或者,该第二UCI包括的ACK比特数少于该第一UCI包括的ACK比特数,或者,该第二UCI的比特数少于该第一UCI的比特数。
步骤S130可以包括:
S131,终端设备在第一PUCCH上发送第一UCI。
具体而言,图6中所示的步骤S110、S120的描述可以参考上述对步骤S110、S120的描述,为了简洁,这里不再赘述。
在S121中,由于将CSI和HARQ进行复用会得到多个UCI。多个UCI对应的PUCCH(资源)可能在时域上重叠。如果将CSI与HARQ复用后形成的多个UCI在时域上不重叠。即承载第一UCI的PUCCH和承载第二UCI的PUCCH在时域上不重叠,则终端设备可以将第一UCI和第二UCI均发送给网络设备。如果多个UCI对应的PUCCH资源在时域上重叠,则终端设备设备需要在多个UCI选择一个发送。以第一UCI和第二UCI为例说明,即承载第一UCI的PUCCH和承载第二UCI的PUCCH在时域上重叠的情况下,终端设备需要丢弃部分UCI,以保证第一时间内的其他UCI的传输。具体的,终端设备可以丢弃第二UCI,在步骤S121中,终端设备丢弃第二UCI,即终端设备只发送第一UCI。其中发送的第一UCI的满足的条件为:所述第一UCI占用的符号数多于或等于所述第二UCI占用的符号数,或者,所述第一UCI包括的肯定应答ACK/否定应答NACK比特数多于或等于所述第二UCI包括的ACK/NACK比特数,或者,所述第一UCI包括的ACK比特数多于或等于所述第二UCI包括的ACK比特数。或者,所述第一UCI的比特数多于或等于所述第二UCI的比特数。
终端设备丢弃的第二UCI满足的条件为:所述第二UCI占用的符号数少于或等于所述第一UCI占用的符号数,或者,所述第二UCI包括的ACK/NACK比特数少于或等于所述第一UCI包括的ACK/NACK比特数,或者,所述第二UCI包括的ACK比特数少于或等于所述第一UCI包括的ACK比特数。或者,所述第二UCI的比特数少于或等于所述第一UCI的比特数。
或者,终端设备可以选择优先级比较高或者比较重要的UCI传输,而丢弃优先级比较低或者不重要的UCI。比如,终端设备根据预先配置的各个UCI的优先级顺序,当第一UCI的优先级高于第二优先级时,只传输第一UCI,或者丢弃第二UCI。优先级顺序可以通过高层信令配置。
在步骤S131中,终端设备只在第一PUCCH上发送第一UCI
应理解,上述的第二UCI满足的条件或者第一UCI满足的条件(或者可以称为丢弃准则)还可以包括其他的条件,本申请在此不作限制。
在步骤121中,需要确定承载第一UCI的PUCCH资源和承载第二UCI的PUCCH资源。因此,需要确定第一UCI的比特数和第二UCI比特数。由于第一UCI包括第一HARQ和CSI,第二UCI包括第二HARQ和CSI。根据承载CSI的第三PUCCH资源、承载第一HARQ的第四PUCCH资源、承载第二HARQ的第五PUCCH资源子时域上的关系,可以确定出承载第一UCI的PUCCH和承载第二UCI的PUCCH。具体的,有如下三种情况:
第一种情况:如果载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源和承载第二HARQ的第五PUCCH资源在时域上均重叠。即第三PUCCH资源与第四PUCCH资源时域上重叠,并且第三PUCCH资源与第五PUCCH资源时域上重叠。则将CSI分别与第一HARQ和第二HARQ复用,得到第一UCI和第二UCI。然后根据第一DCI指示的PUCCH资源确定多个可用于传输第一UCI的PUCCH资源。具体的,第一DCI可以指示4个PUCCH资源,这4个PUCCH resource分别属于预配置的4个PUCCH resource set中。即第一DCI在每个PUCCH resource set中指示可一个PUCCH resource。在将CSI和第一HARQ复用得到第一UCI后,可以确定第一UCI的比特数。根据第一UCI的比特数,确定承载第一UCI的PUCCH资源属于哪一个PUCCH resource set,确定承载第一UCI的PUCCH资源属于哪一个PUCCH resource set后,结合第一DCI指示的PUCCH resource,便可以确定承载第一UCI的第一PUCCH资源。类似的,对于第二UCI,利用类似的方法,便可确定承载第二UCI的第二PUCCH资源,如果第一PUCCH资源和所述第二PUCCH资源在时域上重叠时,则执行步骤S121。如果第一PUCCH资源和所述第二PUCCH资源在时域上不重叠,则分别发送第一UCI和第二UCI。在第一种情况下,承载第一HARQ的第四PUCCH资源和承载第二HARQ的第五PUCCH资源可以在时域上重叠,也可以不在时域上重叠。
第二种情况:如果载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源在时域上不重叠。则将CSI与第一HARQ复用得到第一UCI,然后根据第一UCI的比特数。结合第一DCI可以指示4个PUCCH资源(第四PUCCH资源),确定传输第一UCI的第一PUCCH资源。其中,第一PUCCH资源为第一DCI指示的4个PUCCH resource中的一个,如果第一DCI指示的4个PUCCH resource均不能承载第一UCI,即第一UCI的比特数大于4个PUCCH resource最大的PUCCH resource。则按照CSI的优先级丢弃部分CSI,直到第一DCI指示的4个PUCCH resource中存在可以承载第一UCI的PUCCH resource为止。即承载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源在时域上不重叠时,在第四PUCCH资源上传输(复用)第一UCI。类似的,对于第二UCI,可以将CSI与第二HARQ复用得到第二UCI,然后根据第二UCI的比特数,结合第二DCI可以指示4个PUCCH资源,确定传输第二UCI的第二PUCCH资源。如果第一PUCCH资源和所述第二PUCCH资源在时域上重叠时,则执行步骤S121。如果第一PUCCH资源和所述第二PUCCH资源在时域上不重叠,则分别发送第一UCI和第二UCI。或者,如果承载CSI的第三PUCCH资源与承载第二HARQ的第五PUCCH资源在时域上不重叠时,也可以不将CSI与第二HARQ复用,第二HARQ可以单独传输。或者,如果承载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源在时域上不重叠,可以不将CSI与第一HARQ进行复用,即CSI和第一HARQ分别单独传输。在第二种情况下,承载第一HARQ的第四PUCCH资源和承载第二HARQ的第五PUCCH资源可以在时域上重叠, 也可以不在时域上重叠。
第三种情况:如果载CSI的第三PUCCH资源与承载第二HARQ的第五PUCCH资源在时域上不重叠。则将CSI与第二HARQ复用得到第二UCI,然后根据第二UCI的比特数。结合第二DCI可以指示4个PUCCH资源(第五PUCCH资源),确定传输第二UCI的第二PUCCH资源。其中,第二PUCCH资源为第二DCI指示的4个PUCCH resource中的一个,如果第二DCI指示的4个PUCCH resource均不能承载第二UCI,即第二UCI的比特数大于4个PUCCH resource最大的PUCCH resource。则按照CSI的优先级丢弃部分CSI,直到第二DCI指示的4个PUCCH resource中存在可以承载第二UCI的PUCCH resource为止。即承载CSI的第三PUCCH资源与承载第二HARQ的第五PUCCH资源在时域上不重叠时,在第五PUCCH资源上传输(复用)第二UCI。类似的,对于第一UCI,将CSI与第二HARQ复用得到第二UCI,然后根据第二UCI的比特数,结合第二DCI可以指示4个PUCCH资源,确定传输第二UCI的第二PUCCH资源,其中,第二PUCCH资源为第二DCI指示的4个PUCCH resource中的一个。如果第一PUCCH资源和第二PUCCH资源在时域上重叠时,则执行步骤S121。如果承载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源在时域上不重叠,可以不将CSI与第一HARQ进行复用,即CSI和第一HARQ分别单独传输。
第四种情况:无论承载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源和承载第二HARQ的第五PUCCH资源在时域上是否重叠,即无论承载CSI的第三PUCCH资源与承载第一HARQ的第四PUCCH资源在时域上是否重叠、以及承载CSI的第三PUCCH资源与承载第一HARQ的第五PUCCH资源在时域上是否重叠,都将CSI与第一HARQ复用得到第一UCI,将CSI与第一HARQ复用得到第二UCI。然后根据第一UCI和第二UCI比特数、结合第一DCI指示的PUCCH资源和第二DCI指示的PUCCH资源。确定承载第一UCI的第一PUCCH资源和承载第二UCI的第二PUCCH资源,然后确定第一PUCCH资源和第二PUCCH资源在时域上是否重叠以及是否需要丢弃部分UCI。
作为另一种具体的实现方式,如图7所示,图7是本申请一些实施例中的信息传输的方法的示意性交互图,在一些实施例中,在图5所示的方法步骤的基础上,该方法100的还包括:
S122,根据该第一DCI和第一UCI,在第一PUCCH资源集合中确定第一PUCCH;根据该第二DCI和第二UCI,在第二PUCCH资源集合中确定第二PUCCH,该第一PUCCH资源集合和该第二PUCCH资源集合在时域上不重叠;
上述的步骤S130:终端设备发送该第一UCI和该第二UCI中的至少一个,包括:
S132,终端设备在该第一PUCCH上发送该第一UCI,和/或,在所述第二PUCCH上发送所述第二UCI。
具体而言,由于预先会为第一TRP配置第一PUCCH资源池。例如,第一PUCCH资源池可以包括前述的4个PUCCH resource set,每个PUCCH resource set包括多个PUCCH resource。4个PUCCH resource set可以视为第一PUCCH资源集合。类似的,对于第二TRP也会预先配置的第二PUCCH资源池,第二PUCCH资源池也可以包括多个PUCCH resource,第二PUCCH资源池可以视为第二PUCCH资源集合。并且,所述第一PUCCH 资源集合和所述第二PUCCH资源集合在时域上不重叠。终端设备可以根据所述第一DCI,在第一PUCCH资源集合中确定第一PUCCH资源。具体的,由于第一DCI可以指示4个PUCCH资源,这4个PUCCH resource分别属于预配置的4个PUCCH resource set中。终端设备根据第一DCI,确定这4个PUCCH资源。类似的。终端设备可以根据第二DCI,也可以在第二PUCCH资源集合确定多个PUCCH资源。在确定了4个PUCCH资源后,进一步的根据第一UCI的比特数,在4个PUCCH资源中进一步的确定承载第一UCI的第一PUCCH资源。如果第一DCI指示的4个PUCCH resource均不能承载第一UCI,即第一UCI的比特数大于4个PUCCH resource最大的PUCCH resource。则按照CSI的优先级丢弃部分CSI,直到第一DCI指示的4个PUCCH resource中存在可以承载第一UCI的PUCCH resource为止。类似的,终端设备可以进一步的根据第二UCI的比特数,在第二PUCCH资源集合中进一步的确定承载第二UCI的第二PUCCH资源。由于所述第一PUCCH资源集合和所述第二PUCCH资源集合在时域上不重叠。则可以确定第一PUCCH和第二PUCCH在时域上也不重叠。即确定了传输第一UCI的第一PUCCH资源和传输第二UCI的第二PUCCH资源。并且第一PUCCH资源和第二PUCCH资源在时域上不重叠。
在步骤S131中,终端设备可以在所述第一PUCCH资源上发送所述第一UCI,和/或在所述第二PUCCH资源上发送所述第二UCI。
下面结合具体的例子说明在资源集合中确定PUCCH资源的过程:
具体的,第一TRP配置的PUCCH资源和第二TRP配置的PUCCH资源分别使用两个资源池。两个资源池的PUCCH资源配置部分重叠(或者不重叠)。终端设备先根据第一DCI指示的PUCCH资源确定资源编号。假设对于两个TRP各配置4个PUCCH resource set而言,每个TRP下发的DCI所指示的PUCCH资源编号均对应了4个PUCCH resource set中每个PUCCH resource set中的一个PUCCH资源。终端设备首先基于第一DCI指示的4个PUCCH resource,判断是否与第二TRP的PUCCH资源池中的任意一个PUCCH resource在时域上存在overlap。假设4个PUCCH资源中与第二TRP配置的PUCCH资源池中相比较存在N>0个不overlap的PUCCH resource。若N=1,且4个PUCCH资源中不重叠的PUCCH资源1属于PUCCH resource set 0中的PUCCH resource,由于PUCCH resource set 0中的PUCCH resource资源只能传输第一HARQ,则终端设备只在PUCCH资源1上传输第一HARQ,并不传输CSI。即第一HARQ和CSI在PUCCH资源1上不复用。这样可以降低第一TRP的第一HARQ与第二TRP的第二HARQ发生时域overlap从而被丢弃的风险。如果4个PUCCH资源中与第二TRP配置的PUCCH资源池中相比较存在PUCCH resource属于其他PUCCH resource set(标记为PUCCH resource x1,X1可以为1、2、3中的任意一个值或者多个):则
若当前传输第一HARQ的时间单元内存在CSI,则终端设备根据PUCCH resource x1所能承载的最大UCI比特数判断第一HARQ可以复用的CSI个数。也就是说,第一HARQ+CSI x的比特数应当小于PUCCH resource x1对应的最大UCI比特数。若进一步的第一HARQ+CSI x+CSI y的比特数大于PUCCH resource x1对应的最大UCI比特数时,CSI y被丢弃。若加入任意的CSI均超过PUCCH resource x1对应的最大UCI比特数,则PUCCH resource x1只传输第一HARQ 1而不复用CSI。即在确定了与第二PUCCH资源不重叠的PUCCH resource x1后,进一步的根据PUCCH resource x1的大小确定第一HARQ可以复 用的CSI的个数。保证了第一HARQ的正确传输,进一步的提高了HARQ的传输效率。
若当前传输第一HARQ的时间单元内不存在CSI,则终端设备在PUCCH resource x1传输HARQ 1。
本申请提供的信息传输的方法,通过为不同的UCI选择时域上不重叠PUCCH资源。可以保证多个UCI的正确发送,进一步的确保HARQ传输的成功率,提高通信效率,
可选的,作为一种具体的实现方式,如图8所示,图8是本申请一些实施例中的信息传输的方法的示意性交互图,在一些实施例中,在图5所示的方法步骤的基础上,该方法100的还包括:
S109,终端设备接收指示信息,该指示信息用于指示该CSI与第一HARQ和第二HARQ存在关联关系。
具体而言,由于在本申请实施例中,第一时间单元内的CSI与第一时间单元内的所有HARQ复用。因此,网络设备可以将CSI与第一HARQ和第二HARQ存在关联关系通知给终端设备。该关联关系可以是CSI与第一时间单元内的所有HARQ分别复用,或者,该关联关系还可以是CSI仅与第一时间单元内的某些HARQ复用,例如,CSI与第一时间单元内某些CORESET中的DCI调度的HARQ复用。可选的,该指示信息可以是携带在高层信令中,例如RRC信令。或者,该指示信息可以携带在网络设备发送的配置信息中。
应理解,上述的关联关系还可以是协议预定义或者预配置的,不需要通过指示信息的形式通知给终端设备。
一种实施方式中,当上述关联关系是CSI与所有多个HARQ存在关联关系时,如果在一个时间单元内,只有一个HARQ需要反馈,则终端设备只需要确定第一UCI和发送第一UCI。
可选的,图6和图7所示的方法中也可以包括S109。
在申请的一些实施例中,第一控制资源集合用于承载所述第一DCI,第二控制资源集合用于承载所述第二DCI,所述第一控制资源集合与所述第二控制资源集合不同。
具体而言,由于DCI利用控制资源集合承载的。控制资源集合包括用于网络设备发送PDCCH(DCI)的所占的时频资源信息。第一DCI承载于第一控制资源集合上,第二DCI承载于第二控制资源集合上。由于所述第一控制资源集合与所述第二控制资源集合不同,证明第一DCI和第二DCI是由不同的TRP发送的。即不同的控制资源集合对应不同的TRP。第一TRP利用第一控制资源集合向终端设备发送第一DCI,第二TRP利用第二控制资源集合向终端设备发送第一DCI。第一TRP对应第一HARQ,第二TRP对应第二HARQ。即第一HARQ和第二HARQ需要向不同的网络设备反馈。
应理解的,终端设备若在第一控制资源集合上检测到了多个DCI,则意味着该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合并成一个bitmap 1,若在第二控制资源集合上检测到了多个DCI,则意味着该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合成一个bitmap 2,bitmap 1和bitmap 2分别承载于两个PUCCH上;也可以将控制资源集合进行分组,比如第一控制资源集合组和第二控制资源集合组,若在第一控制资源集合组上检测到了多个DCI,则将该DCI调度的PDSCH对应的HARQ反馈比特需要依次合并成一个bitmap 1,若在第二控制资源集合组上检测到了多个DCI,则意味着该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合成一个bitmap 2,bitmap  1和bitmap 2分别承载于两个PUCCH上;还可以根据DCI中特定的字段指示的信息确定,比如,若多个DCI均指示CDM组0,则该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合并成一个bitmap 1,若多个DCI均指示CDM组1,则该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合并成一个bitmap 2,再比如,还可以根据检测到的DCI的扰码确定,比如若检测到的多个DCI均通过扰码1加扰,则该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合并成一个bitmap 1,如若检测到的多个DCI均通过扰码2加扰,则该多个DCI调度的PDSCH对应的HARQ反馈比特需要依次合并成一个bitmap 2。
可选的,S109中接收的指示信息还可以用于指示CSI与该第一控制资源集合和该第二控制资源集合存在关联关系。其中,指示信息中的每一个比特域字段值均对应一个或者一组不同的CORESET索引值,或者CORESET组的索引值,也可以对应一个BWP内或者一个载波内全部CORESET的索引值,比如,一个BWP内配置了CORESET 0和CORESET 1,则该指示信息的比特’00’可以指示CORESET 0,’01’可以指示CORESET 1,’10’可以指示CORESET 0和CORESET 1。则终端设备根据该关联关系指示信息确定可以与CSI合并的HARQ比特,从而经过合并可以形成一个bitmap承载于一个PUCCH资源上,比如,该指示信息指示’10’,则CSI可以与CORESET 0上接收到的DCI对应的HARQ合并,也可以与CORESET 1上接收到的DCI对应的HARQ合并。
可选的,该指示信息也可以为CORESET组索引值,即每个CORESET配置中包含一个表征CORESET组的索引值,索引值相同的CORESET意味着属于同一组,则在同一组CORESET上接收到的DCI对应的HARQ可以合并,该CORESET组索引值配置在CSI配置信息中,表示,CSI的比特可以与配置的CORESET或者CORESET组对应的控制资源集合上检测到的DCI对应的HARQ比特合并,合并后的UCI比特承载于一个PUCCH资源上。
本申请提供的信息传输的方法,多站点协作传输中,通过改变CSI和HARQ之间的关联关系,使得CSI与传输CSI的时间单元内的HARQ关联,使得CSI与传输CSI的时间单元内的HARQ可以复用形成UCI。可以保证CSI的正常传输。提高通信效率。进一步的,在选择HARQ传输的资源时,通过为每个HARQ选择重叠的时域资源,保证了HARQ的正确传输,进一步的提高了HARQ的传输效率。
应理解,在本申请的各个实施例中,第一、第二等只是为了表示多个对象是不同的。例如第一DCI和第二DCI只是为了表示出不同的DCI。而不应该对DCI的本身和数量等产生任何影响,上述的第一、第二等不应该对本申请的实施例造成任何限制。
可以理解的,在不冲突的情况下,本申请各实施例可以应用于多个TRP的场景,即在同一个时间单元内有多个HARQ需要反馈,并不限于只有第一HARQ和第二HARQ。
应理解,本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便,不应构成特别的限定,各种方式、类别、情况以及实施例中的特征在不矛盾的情况下可以相结合。
还应理解,在本申请的实施例中涉及的各种数字编号仅为描述方便进行的区分,并不用来限制本申请的实施例的范围。上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任 何限定。
还应理解,上述只是为了帮助本领域技术人员更好地理解本申请实施例,而非要限制本申请实施例的范围。本领域技术人员根据所给出的上述示例,显然可以进行各种等价的修改或变化,例如,上述方法100中某些步骤可以是不必须的,或者可以新加入某些步骤等。或者上述任意两种或者任意多种实施例的组合。这样的修改、变化或者组合后的方案也落入本申请实施例的范围内。
还应理解,上文对本申请实施例的描述着重于强调各个实施例之间的不同之处,未提到的相同或相似之处可以互相参考,为了简洁,这里不再赘述。
还应理解,本申请实施例中,“预定义”可以通过在设备(例如,包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。
