另外，在本申请实施例中，“可选地”或者“示例性地”等词用于表示作例子、例证或说明。本申请实施例中被描述为“可选地”或者“示例性地”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。
在本申请实施例中，一个面板可以对应一个端口组(例如，天线端口组，或者，天线组)，上述面板与端口组呈一一对应关系，两者可以相互替换，面板也可以用空间参数代替。进一步地，上述面板可以指天线面板，一个TRP或者接收端可以包括至少一个天线面板。每个面板上有一个或者多个天线阵子，多个天线阵子可以虚拟成一个天线端口。一个面板上的天线端口可以分为一个端口组，另外，一个面板又可以分成多个子面板，每个子面板包括的多个天线端口也可以分为一个端口组。以双极化的天线为例，正45°极化的天线为一个子面板，负45°极化的天线为另一个子面板。在本申请实施例中，将面板和子面板统称为面板，可以用panel表示。
在传输数据或信令时，标准中通常将物理信道分为物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。PDCCH主要用于传输物理下行控制信令(Downlink Control Information，DCI)，PUCCH主要用于传输上行控制信息，比如信道状态信息(Channel State Information，CSI)、混合自动重传请求(Hybrid automatic repeat request，HARQ)、调度请求(Scheduling Request)等，PDSCH主要用于传输下行数据，PUSCH主要用于传输上行数据和CSI等信息，进一步地，可以将PDCCH和PUCCH可以统称为物理控制信道，将PUSCH和PDSCH可以统称为物理共享信道。
进一步地，上述CSI包括接收端反馈的下行链路的信道状态信息和发送端指示接收端的上行链路的信道状态信息，其中，下行链路的信道状态信息包括但不限于以下信息之一：信道状态信息-参考信号资源指示(CSI-RS Resource Indicator，CRI)、同步信号块资源指示(Synchronization Signals Block Resource Indicator，SSBRI)、信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、层指示(Layer Indicator，LI)、秩指示(Rank Indicator，RI)，上行链路的信道状态信息包括但不限于以下信息之一：上行探测信号资源指示(SRS resource Indicator，SRI)、传输预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)、传输秩指示(Transmitted Rank Indicator，TRI)、调制和编码方案(Modulation and coding scheme，MCS)，另外TPMI和TRI可能联合编码，使用下行控制信令的预编码和层数(Precoding information and number of layers)指示。
在重复传输数据时，比如重复传输M(M为大于1的整数)个PDSCH或PUSCH，是指重复传输的M个数据携带了完全相同的信息，例如，M个数据来自相同传输块(Transport Block，TB)，只是对应的信道编码后的冗余版本(Redundancy version，RV)不同，甚至M个数据信道编码后的RV是相同的，或者是同一个传输块的信息的同一个RV被分成不同的层进行传输，其中，RV指对传输数据进行信道编码后的不同冗余版本，一般来说，可以取信道版本{0，1，2，3}。同样地，重复传输信令，比如重复传输PDCCH或PUCCH，是指重复传输的M个信令携带的内容是相同的，例如，M个PDCCH携带的DCI内容是相同的(比如，每个域的取值相同)，或者，M个PUCCH携带的内容取值是相同的。
进一步地，M个重复传输的数据或者信令可以来自M个不同的TRP，或者M个不同的天线面板，或者M个不同的带宽部分(Bandwidth Part，BWP)，或者，M个不同的载波组件(Carrier Component，CC)，其中，M个面板或者BWP或者CC可以属于同一个TRP，也可以属于多个TRP。M个重复传输的数据或者信令也可以只来自同一个传输节点的不同传输时隙(slot)或者子时隙(sub slot)。进一步地，重复传输的方案包括但不限于以下至少方式之一：空分复用的方式Scheme 1，频分复用的方式Scheme 2，时隙内的时分复用的方式传输Scheme 3，时隙间的时分复用的方式Scheme 4。根据传输块的RV是否相同，又可以将频分复用的方式Scheme 2分为两类，当重复传输的数据对应的RV相同时或者重复传输的数据来自同一个传输块的不同层时，为Scheme2a，当重复传输的数据对应的RV不同时，为Scheme2b。
还可以是上述复用方式的任意组合，比如空分复用和频分复用的组合，时分复用和频分复用的组合等。另外，上述时隙是指包括L个符号的集合，子时 隙是指包括K1个符号的集合，一般来说，K1为正整数，且小于或等于L，L可以为14或者12，K1可以为2-13中的任意值，或者2，4，7。
另外，PDCCH是需要映射到一组资源单元(Resource Element，RE)上的，其中，一个控制信道单元(Control Channel Element，CCE)可以包含多个RE，一个RE在频域上包括一个子载波，在时域上包括一个符号。用于传输PDCCH的一个或者多个CCE的集合，可以称之为控制资源集合(Control resource set，CORESET)，其在频域上包括多个物理资源块，而在时域上包括K2个符号，K2为自然数，比如K2可以取1、2、3的整数。这里的符号可以包括但不限于以下之一：正交频分复用符号(Orthogonal Frequency Division Multiplex，OFDM)，单载波频分多址接入(Single-Carrier Frequency Division Multiple Access，SC-FDMA)，正交频分多址接入(Orthogonal frequency division Multiple Access，OFDMA)。
为了传输PUSCH或者PDSCH，可以将连续K3个符号和L1个频域子载波的一组RE形成一个资源块(Resource block，RB)，或称之为物理资源块(Physical Resource block，PRB)，K1和L1均为正整数，比如K3＝12或者14，L1＝12。
PDSCH、PDCCH、PUSCH、PUCCH等物理信道都是调制在最小的资源单元RE中，每个RE包括时域的一个符号和频域的一个子载波。为了解调或者获取RE上调制的物理信道上携带的信息(包括数据或者信号)，需要估计RE上无线信道的值，这个值一般可以由解调参考信号(Demodulation Reference Signal，DMRS)估计获得，并用DMRS对应的RE上的信道插值获得物理信道上的信道。
另外，在本申请实施例中，若无特别说明，一般包括1个接收端和至少1个TRP。为了提高传输数据或者信令的可靠性，发送端对数据或者信令进行N次重复传输，比如重复传输N次PDSCH、PUSCH、PDCCH、PUCCH中的至少之一。发送端在下行链路中可以是各类网络侧设备，比如各类传输节点，宏发送端、微发送端、微微发送端，中继等网络侧设备，在上行链路中可以为手机、便携设备、电脑、数据卡等接收端。相应地，接收端在下行链路中可以为接收端，在上行链路中可以为网络侧设备。N次重复传输的数据或者信令可以来自同一个发送端，也可以来自不同的发送端，或者可以来自相同或不同的发送端的不同面板，N个重复传输的数据或者信令可以通过空分复用，或者频分复用，或者时分复用的方式进行传输。
在本申请实施例中，参考信号可以包括但不限于以下至少之一：DMRS、信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)资源、同步信号块(Synchronization Signals Block，SSB)资源、物理广播信道 (Physical Broadcast Channel，PBCH)资源、同步广播块/物理广播信道(SSB/PBCH)资源、上行探测参考信号(Sounding reference signal，SRS)资源、定位参考信号(Positioning Reference Signals，PRS)，相位跟踪参考信号(Phase-tracking reference signal，PTRS)。接收端或发送端在接收到传输块之后，若检测发现接收是正确的，则反馈一个确定信息(Acknowledgement，ACK)，若检测发现接收是错误的，则反馈一个否定信息(Negative Acknowledgement，NACK)。发送端也可能并不反馈NACK信息，只是不对资源进行调度或者分配，以通知接收端后续不需要进行PUSCH的传输即可。
在本申请实施例中，参考信号的密度是指用于传输参考信号的RE占整个传输资源的比例，或者在一个RB中，用于传输参考信号的RE占整个RB所包括的RE的比例。
本实施例中，空间参数包括但不限于发送波束、接收波束、准共位置类型type D、发送波束组、接收波束组、射频波束、空间接收参数(Spatial Rx parameter)、传输配置指示(Transmission configuration indication，TCI)、波束索引、波束组索引、准共位(quasi co-location)中的部分参数信息指示等。
在本申请实施例中，传输可以为发送或接收中的任意一种方式，对于下行信道(例如，PDCCH或者PDSCH)而言，发送端可以理解为各类网络侧设备(例如，基站)，接收端可以理解为终端，对于上行信道(例如，PUCCH或者PUSCH)而言，发送端可以理解为终端，接收端可以理解为各类网络侧设备。即发送端重复传输某个数据或信令，可以为发送端向接收端重复发送某个数据或信令，相应地，接收端接收发送端重复发送的某个数据或信令。
在上述概念的基础上，图1示出本申请实施例的物理信道传输方法的流程图。如图1所示，该方法可以应用于发送端，该方法可以包括：
S101、发送端获取K份参考信号参数。
上述K份参考信号参数可以用于N次物理信道的重复传输，其中，K和N为大于1的整数，且N大于或等于K。参考信号参数可以包括参考信号的资源单元个数、参考信号的密度、参考信号的符号个数、参考信号的发射功率中的至少一个。进一步地，参考信号参数的配置也可以包括参考信号的图样(pattern)、参考信号的功率偏置、PUSCH的传输类型、PUSCH是否跳频、PUCCH的传输类型、PUCCH是否跳频等，其中，参考信号的图样可以包括1个RB中参考信号所占的RE个数、comb数目、RE密度等，发射功率或者功率偏置为相对于以下之一的提升量：数据、同步广播块/物理广播信道块SSB、信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)。
进一步地，可以将上述N次重复传输分为K组，每组重复传输使用相同的参考信号参数，比如包括重复传输索引连续的n1次重复传输，这里，n1为正整数，比如，n1＝f(N/K)，f表示对一个实数上取整或者下取整，N/K表示N除以K。若N不能被K整除，那么当f为上取整时，有的重复传输组可能包括n1-1个重复传输，当f为下取整时，有的重复传输组可能包括n1+1个重复传输。第i组重复传输对应第i份参考信号参数，i＝1，…，K。
K份参考信号参数对应M个空间参数信息，和/或，N次物理信道的重复传输对应M个空间参数信息，M为大于或等于K，且小于或等于N的正整数。示例性地，可以将M个空间参数分为K组，每组空间参数对应一份参考信号参数。每组空间参数信息包括n2个空间参数信息，这里，n2为正整数，比如，n2＝f(M/K)，f表示对一个实数上取整或者下取整，M/K表示M除以K。如果M不能被K整除，那么当f为上取整时，有的重复传输组可能包括n2-1个重复传输，而在f为下取整时，有的重复传输组可能包括n2+1个重复传输。
进一步地，发送端获取的上述K份参考信号参数可以为发送端预配置的参数，或者发送端通过高层信令获取的参数。发送端预配置K份参考信号参数可以理解为发送端与接收端约定配置的K份参考信号参数，通过高层信令(例如，无线资源控制(Radio Resource Control，RRC)、媒体接入控制单元(Media Access Control control element，MAC CE)或物理层信令)获取K份参考信号参数可以理解为发送端通过高层信令配置K份参考信号参数，或者通过高层信令或物理层接收其他节点传输的K份参考信号参数。
示例性地，当发送端为网络侧设备时，该发送端可以通过高层信令配置K份参考信号参数，并将K份参考信号参数通过高层信令或物理层信令发送至接收端；当发送端为终端时，该发送端可以通过高层信令或者物理层信令获取其他节点(比如网络侧设备)传输的K份参考信号参数。
进一步地，在上述K份参考信号参数中，发送端可以预配置部分参考信号参数，例如，假设其中k份参考信号参数是由发送端预配置的，其余K-k份参考信号参数是通过高层信令获取的。例如，根据k＝1份参考信号参数按照约定的方式获取k份参考信号参数，并根据参考信号的符号个数可以逐步增加的方式获得K-k份其它的参考信号参数配置，至于参考信号的符号个数增加的参考信号符号索引位置也可以通过预配置的方式获得。
S102、发送端根据K份参考信号参数进行物理信道的重复传输。
基于步骤S101，发送端获取到K份参考信号参数后，由于K份参考信号参数用于N次物理信道的重复传输，那么发送端在进行N次重复传输的过程中，另一节点(例如，接收端)接收第j次重复传输，则发送端可以对小于或等于j 次的重复传输所获得的信息进行合并以获得合并增益，并在解调成功后反馈ACK信息，以避免占用过多的重复传输资源，并保证传输的可靠性。本实施例提供的物理信道传输方法，在重复传输过程中，可以提高重复传输的解调性能。
在一种示例中，上述步骤S102的重复传输方式可以为以下几种方式中的至少一种：方式一、发送端第j次重复传输对应的参考信号的符号个数大于或等于第i次重复传输对应的参考信号的符号个数，其中，1≤i＜j≤N；方式二、发送端第j次重复传输对应的参考信号的发送功率大于或等于第i次重复传输对应的参考信号的发送功率，其中，1≤i＜j≤N；方式三、发送端第j次重复传输对应的参考信号的资源单元个数大于或等于第i次重复传输对应的参考信号的资源单元个数，其中，1≤i＜j≤N；方式四、发送端第j次重复传输对应的参考信号的密度大于或等于第i次重复传输对应的参考信号的密度，其中，1≤i＜j≤N。
进一步地，上述步骤S102的重复传输方式还可以包括以下几种情况中的至少一种：第一种情况，当发送端重复传输对应的资源符号个数大于L时，发送端第j次重复传输对应的参考信号的符号个数大于或等于第i次重复传输对应的参考信号的符号个数，其中，L为大于1的整数，1≤i＜j≤N；第二种情况，在第n次重复传输后，发送端第j次重复传输对应的参考信号的发送功率大于或等于第i次重复传输对应的参考信号的发送功率，1＜n≤j，1≤i＜j≤N；第三种情况，当发送端m次重复传输成功后，结束重复传输，m大于k，其中，1＜k＜N，即发送端在某次重复传输成功之后，而该重复传输次数还未到达总传输次数时，可以结束重复传输。
进一步地，当物理信道为PDSCH或PUSCH时，上述发送端重复传输对应的资源符号个数大于L时，L的取值可以为大于7的整数，进一步地，当PDSCH传输类型为A时，L的取值可以为8，当PDSCH传输类型为B时，L的取值可以为7。当不跳频时，若PUSCH传输类型为A，则L的取值可以为8，否则L的取值为7，在跳频时，K的取值为5。当物理信道为PUCCH时，上述发送端重复传输对应的资源符号个数大于L时，L的取值可以为大于2的整数。
在另一种实施例中，上述步骤S102中发送端根据K份参考信号参数进行物理信道的重复传输可以为发送端第j次重复传输对应的参考信号的符号个数小于第i次重复传输对应的参考信号的符号个数，其中，1≤i＜j≤N；或者，当发送端重复传输对应的资源符号个数大于L时，发送端第j次重复传输对应的参考信号的符号个数小于第i次重复传输对应的参考信号的符号个数，其中，L为大于1的整数，1≤i＜j≤N；或者，发送端第j次重复传输对应的参考信号的资源单元个数小于第i次重复传输对应的参考信号的资源单元的个数，其中，1≤i＜j≤N；或者，发送端第j次重复传输对应的参考信号的密度小于第i次重复传输 对应的参考信号的密度，其中，1≤i＜j≤N。
这样通过不断减小解调参考信号的开销，以增加信道的编码率，从而提高解调的准确性。
在另一种示例中，当物理信道为物理共享信道时，上述步骤S102中，发送端进行物理信道的重复传输可以为以下方式中的至少之一：方式一、发送端第j次重复传输对应的共享数据对应的调整编码阶数大于第i次重复传输对应的共享数据对应的调整编码阶数，其中，1≤i＜j≤N；方式二、发送端接收到NACK时，第j次重复传输对应的参考信号的发送功率大于第i次重复传输对应的参考信号的发送功率，其中，1≤i＜j≤N；方式三、若发送端接收到ACK后，结束后续的重复传输。例如，在第k次重复传输后，发送端接收到ACK信息后，那么第k+1至N次的重复传输将不需要执行。
另外，在本申请实施例中，上述重复传输可以为通过一个网络侧设备(例如，基站)在不同的时隙或者子时隙传输，也可以通过多个网络侧设备在不同的时隙或者子时隙以时分复用的方式传输，或者至少一个网络侧设备的多个面板在不同的时隙或者子时隙通过时分复用的方式传输。进一步地，上述重复传输也可以为以至少一个网络侧设备的至少一个面板通过空分复用的方式，或者频分复用的方式传输。
图2示出本申请实施例的另一物理信道传输方法的流程图，如图2所示，该方法可以应用于接收端，该方法可以包括：
S201、接收端获取K份参考信号参数。
上述K份参考信号参数可以用于接收N次物理信道的重复传输，其中，K和N为大于1的整数，且N大于或等于K。参考信号参数可以包括参考信号的资源单元个数、参考信号的密度、参考信号的符号个数、参考信号的发射功率中的至少一个。进一步地，参考信号参数的配置也可以包括参考信号的图样(pattern)、参考信号的功率偏置、PUSCH的传输类型、PUSCH是否跳频、PUCCH的传输类型、PUCCH是否跳频等，其中，参考信号的图样可以包括1个RB中参考信号所占的RE个数、comb数目、RE密度等，发射功率或者功率偏置为相对于数据或者同步广播块/物理广播信道块SSB或者信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)的提升。
进一步地，可以将上述N次重复传输分为K组，每组重复传输使用相同的参考信号参数，比如包括重复传输索引连续的n1次重复传输，这里，n1为正整数，比如，n1＝f(N/K)，f表示对一个实数上取整或者下取整，N/K表示N除以K。若N不能被K整除，那么当f为上取整时，有的重复传输组可能包括n1-1个重 复传输，当f为下取整时，有的重复传输组可能包括n1+1个重复传输。第i组重复传输对应第i份参考信号参数，i＝1，…，K。
K份参考信号对应M个空间参数信息，和/或，N次物理信道的重复传输对应M个空间参数信息，M为大于或等于K，且小于或等于N的正整数。示例性地，可以将M个空间参数分为K组，每组空间参数对应一份参考信号参数，即每组空间参数和一份参考信号参数关联，比如第i组空间参数与第i份参考信号参数关联，用第i组空间参数传输的物理信道重复传输对应的第i份参考信号参数配置的参考导频。每组空间参数信息包括n2个空间参数信息，这里，n2为正整数，比如，n2＝f(M/K)，f表示对一个实数上取整或者下取整，M/K表示M除以K。如果M不能被K整除，那么当f为上取整时，有的重复传输组可能包括n2-1个重复传输，而在f为下取整时，有的重复传输组可能包括n2+1个重复传输。
在本步骤中，接收端获取的上述K份参考信号参数可以为接收端预配置的参数，或者接收端通过高层信令获取的参数。接收端预配置K份参考信号参数可以理解为发送端与接收端约定K份参考信号参数，接收端通过高层信令获取参数可以理解为接收端通过高层信令配置K份参考信号参数，或者，通过高层信令或物理层信令获取其他节点传输的K份参考信号参数。
进一步地，在上述K份参考信号参数中，接收端可以预配置部分参考信号参数，例如，假设其中k份参考信号参数是由接收端预配置的，其余K-k份参考信号参数是通过高层信令获取的。例如，根据k＝1份参考信号参数按照约定的方式获取k份参考信号参数，并根据参考信号的符号个数可以逐步增加的方式获得K-k份其它的参考信号参数配置，至于参考信号的符号个数增加的索引位置也可以预配置的方式获得。
S202、接收端根据K份参考信号参数接收物理信道的重复传输。
接收端获取到K份参考信号参数后，由于K份参考信号参数用于接收N次物理信道的重复传输，那么接收端在接收N次重复传输的过程中，若接收到发送端传输的第j次重复传输，可选地，可以对小于或等于j次的重复传输获得的信息进行合并以获得合并增益。
在一种示例中，上述步骤S202接收重复传输的方式可以为以下几种实现方式中的至少之一：方式一、接收端接收的第j次重复传输对应的参考信号的符号个数大于或等于接收的第i次重复传输对应的参考信号的符号个数；方式二、接收端接收的第j次重复传输对应的参考信号的发送功率大于或等于接收的第i次重复传输对应的参考信号的发送功率，其中，1≤i＜j≤N；方式三、接收端接收的第j次重复传输对应的参考信号的资源单元个数大于或等于接收的第i次重复 传输对应的参考信号的资源单元个数，其中，1≤i＜j≤N；方式四、接收端接收的第j次重复传输对应的参考信号的密度大于或等于接收的第i次重复传输对应的参考信号的密度，其中，1≤i＜j≤N。
进一步地，上述步骤S202中接收重复传输的方式还可以包括以下几种情况中的至少一种：第一种情况，当接收端接收的重复传输对应的资源符号个数大于L时，接收端接收的第j次重复传输对应的参考信号的符号个数大于或等于其接收的第i次重复传输对应的参考信号的符号个数，其中，L为大于1的整数，1≤i＜j≤N；第二种情况，当接收端在接收第n次重复传输后，接收端接收的第j次重复传输对应的参考信号的发送功率大于或等于接收的第i次重复传输对应的参考信号的发送功率，1＜n≤j，1≤i＜j≤N；第三种情况，当接收端m次重复传输接收成功后，结束接收重复传输，m大于k，其中，1＜k＜N，即接收端在某次重复传输接收成功之后，而该重复传输次数还未到达总传输次数时，可以结束重复传输的接收。
进一步地，当物理信道为PDSCH或PUSCH时，上述接收端接收的重复传输对应的资源符号个数大于L时，L的取值可以为大于7的整数，进一步地，当PDSCH传输类型为A时，L的取值可以为8，当PDSCH传输类型为B时，L的取值为7。当不跳频时，若PUSCH传输类型为A，则L的取值可以为8，否则L的取值为7，在跳频时，K的取值为5。当物理信道为PUCCH时，上述接收端接收的重复传输对应的资源符号个数大于L时，L的取值可以为大于2的整数。
在另一种实施例中，上述步骤S202中接收端根据K份参考信号参数接收物理信道的重复传输可以为接收端接收的第j次重复传输对应的参考信号的符号个数小于接收的第i次重复传输对应的参考信号的符号个数，其中，1≤i＜j≤N；或者，当接收端接收的重复传输对应的资源符号个数大于L时，接收端接收的第j次重复传输对应的参考信号的符号个数小于接收的第i次重复传输对应的参考信号的符号个数，其中，L为大于1的整数，1≤i＜j≤N；或者，接收端接收的第j次重复传输对应的参考信号的资源单元个数小于接收的第i次重复传输对应的参考信号的资源单元的个数，其中，1≤i＜j≤N；或者，接收端接收的第j次重复传输对应的参考信号的密度小于接收的第i次重复传输对应的参考信号的密度，其中，1≤i＜j≤N。
这样通过不断减小解调参考信号的开销，以增加信道的编码率，从而提高解调的准确性。
在另一种示例中，当物理信道为物理共享信道时，上述步骤S202中，接收端接收物理信道的重复传输可以为以下几种方式中的至少之一：
方式一、接收端接收的第j次重复传输对应的共享数据对应的调整编码阶数大于接收的第i次重复传输对应的共享数据对应的调整编码阶数，其中，1≤i＜j≤N。
方式二、接收端接收的向发送端反馈否定信息时，接收的第j次重复传输对应的参考信号的发送功率大于接收的第i次重复传输对应的参考信号的发送功率。
进一步地，当物理信道为PUSCH时，若接收端给发送端分配了重复传输资源，则接收第j次重复传输对应的参考信号的发送功率大于接收第i次重复传输对应的参考信号的发送功率，其中，1≤i＜j≤N。
方式三、若接收端成功解调PUSCH后，向发送端反馈ACK或者不再给发送端分配重复传输的资源，那么接收端不再接收PUSCH后续的重复传输。
方式四、当物理信道为PUSCH时，若接收端停止向发送端分配重复传输资源，则结束后续对重复传输的接收。例如，在第k次重复传输后，接收端停止向发送端分配重复传输资源，那么第k+1至N次的重复传输将不需要执行。
另外，在本申请实施例中，上述重复传输可以为通过一个网络侧设备在不同的时隙或者子时隙传输，也可以通过多个网络侧设备在不同的时隙或者子时隙以时分复用的方式传输，或者至少一个网络侧设备的多个面板在不同的时隙或者子时隙通过时分复用的方式传输。进一步地，上述重复传输也可以为以至少一个网络侧设备的至少一个面板通过空分复用的方式，或者频分复用的方式传输。
