此外，在本申请实施例中，终端设备还可以是物联网系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
此外，在本申请实施例中，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。

在无线通信系统中，按照发送节点和接收节点种类的不同，可以将通信分为不同的类型。通常，将网络设备向终端设备发送信息称为下行(downlink，DL)通信，将终端设备向网络设备发送信息称为上行(uplink，UL)通信。在第五代无线通信系统—NR系统中，在时域上可以划分为多个无线帧，每个无线帧长10ms；一个无线帧又包括多个时隙。一个时隙(slot)可以包括14个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。
在时域上，最小的资源粒度是一个OFDM符号，在频域上，最小的粒度是一个子载波。一个OFDM符号与一个子载波组成的一个时频资源单元(resource element，RE)，为信号传输的时频域上最小的传输单位RE，物理层在进行资源映射的时候，是以RE为基本单位的。一个时隙内所有的OFDM符号与频域上12个子载波组成一个资源块(resource block，RB)。一个时隙中的OFDM符号的传输方向可以为DL，UL，或者灵活(flexible)，而一个时隙中的OFDM符号的传输方向组合可以理解为该时隙的格式。例如，目前NR的TS 38.211标准中，规定了若干时隙的格式，摘录部分如表1所示：
表1
Figure PCTCN2020120301-appb-000001
表1中，D代表DL，U代表UL，X代表灵活。以时隙格式类型序号为27为例，格式27代表的时隙格式为：前3个OFDM符号进行DL传输，最后3个OFDM符号为UL传输，中间的8个OFDM符号为灵活，即可能为上行、可能为下行、也可能不用于传输。本申请中，将时隙格式类型序号为0的slot称为下行slot，将时隙格式类型序号为1的slot称为上行slot。一般实际通信中，主要使用这两种格式的slot。
无论UE在上行slot向gNB发送的物理上行共享信道(physical uplink shared channel，PUSCH)，还是gNB在下行slot向UE发送的物理下行共享信道(physical downlink shared channel，PDSCH)，一般都包含两部分：数据和DMRS。接收端只有通过DMRS正确估计出信道后，才能对数据进行解调，因此DMRS也是数据传输中的重要部分。
参见图2，图2的(a)是类型1的上行DMRS图样的示意图，图2的(b)是类型2的上行DMRS图样的示意图。NR的上、下行传输支持相同的DMRS配置，例如图2所示，在一个RB中，无论是PDSCH还是PUSCH，均可以采用将DMRS放置在第3，4个(对应图2中的符号序号2和3)OFDM符号的发送图样。
两种类型的DMRS图样差别主要在于支持的CDM组数不同，类型1的上行DMRS图样支持2个CDM组(图2的(a)中2种不同的填充格子代表2个CDM组)和类型2的上行DMRS图样支持3个CDM组(图2的(b)中3种不同的填充格子代表3个CDM组)。作为示例而非限定，本申请以类型2的DMRS图样进行举例说明，但本申请的实施例均同时适用于类型1和类型2，本申请对此不作具体限定。类型2的DMRS图样中配置了“双符号”(序号2和3对应的符号)，即DMRS由频域上连续的两个符号组成，因此DMRS在每个RB内共占用24个RE。这24个RE如图2的(b)中分为三组，即三个CDM组；每组包括8个RE，这8个RE在频域上分成不连续的两个“时频连续4RE组”，使用相同的叠加正交码(orthogonal cover code，OCC)序列，支持4个OCC正交的DMRS。其中，OCC正交是指相同的DMRS基序列，分别乘以不同的OCC序列，从而达成正交的一种DMRS发送方案。例如：相同的DMRS基序列记为[s1s2s3s4……],四组正交OCC分别为：[1,1,1,1]、[1,-1,1,-1]、[1,1,-1,-1]、[1,-1,-1,1]，则4个OCC正交的DMRS分别为：[s1,s2,s3,s4,……]、[s1,-s2,s3,-s4,……]、[s1,s2,-s3,-s4,……]、[s1,-s2,-s3,s4,……]。
需要说明的是，一个DMRS在不同频域位置的“时频连续4RE组”中使用的OCC序列相同。因此，即使有再多的“4RE组”，也仍然只能支持4个OCC正交DMRS。此外，实际场景中的一些非理想因素，会影响上述OCC的正交性。本申请中考虑时间提前量不准导致的OCC非正交。此时，CDM组间的DMRS依然是正交的，但组内原本OCC正交的DMRS变得不再正交。
NR支持TDD。具体来说，网络设备可以通过将上行slot和下行slot交替配置在相同的一个载波上实现TDD。时域下行、上行slot的比例，称为TDD上下行配比。例如8:2就是现网中一个非常常见的TDD上下行配比方案，即每10个slot中包含8个连续的下行slot，后面接着2个连续的上行slot。该配比中下行slot数量远大于上行slot，是因为一般蜂窝小区中主要以下行业务为主，但也不排除个别以上行业务为主的小区存在，例如适用于工厂场景中的工厂微小区。
参见图3，图3是适用于本申请实施例的工厂宏微场景的示意图。该场景中包含宏小区和微小区两个小区。该场景中涉及的关键网元包括：宏基站(简称宏站)、宏UE、微基站(简称微站)、微UE。涉及的关键链路包括两个：一是微小区内实线1代表的微UE到微站的上行链路，在该链路上，主要是微UE向微站发送上行数据；二是虚线2代表的宏站到微站的下行链路(这里可以把微站当做宏站的一个UE来看，称其为下行)，在该链路上，宏站在发送下行数据，微站可能会受到宏站下行数据的干扰。作为一种示例，在工厂微小区中，每一个高清摄像头(即微UE的一例)对应一台机器进行录像监控，以判断机器是否正常运转。这使得工厂微小区中，业务的主要方向是上行，即摄像头向网络设备传输实时录制的视频。为满足上行业务需求，微小区的上下行配比以上行slot为主。
在这种场景下，宏站使用常规的下多上少的上下行配比(例如图3中室外5个slot为 DSUDD，S为专用帧，可以理解为D)，微站使用上多下少的上下行配比(例如图3中室内5个slot为USUUU)。这就导致了对于同一slot(例如第1、4、5个slot)，对于宏站来说是下行，但对于微站来说是上行。作为示例而非限定，本申请中称如上述示例中的第1、4、5个slot这样的slot为宏微异配比slot，也可以简称异配比slot。宏站在异配比slot向自己服务的宏UE发送下行数据，而这一下行数据也恰好会被正要接收微UE发送上行数据的微站所接收到，造成邻区干扰。典型工厂宏微场景中，微站受到宏站同频干扰的水平-50dBm，需要采用一定的技术手段进行同频干扰-50dBm的干扰消除来满足工厂容量的期望干扰水平-90dBm，此时微站需要对发射端宏站发送的下行数据的信道进行准确的估计。在微站接收端，可采用迭代干扰消除算法，消除宏站下行数据造成的同频干扰，可以获得较好的干扰消除效果。
发射端的预编码和接收端的信道估计可以分为子带和宽带两种，子带和宽带的区别在于子带是以预编码资源组(precoding resource group，PRG)为粒度(例如：NR标准中1个PRG＝2或4个RB)，在每个PRG内独立进行操作；而宽带是在被调度的全部资源内统一的操作。实际系统中可选以下三种预编码+信道估计的组合：子带预编码+子带信道估计，宽带预编码+子带信道估计或者宽带预编码+宽带信道估计。其中，子带编码是一种以信号频谱为依据的编码方法，即将信号分解成不同频带分量来去除信号相关性，再将分量分别进行取样、量化、编码，从而得到一组互不相关的码字合并在一起后进行传输，子带预编码的优势在于充分利用频选信道中每一个PRG上的信道信息，针对每个PRG独立设计预编码，使得预编码性能最优。宽带预编码的优势在于可以让接收端使用宽带信道估计，信道估计的抗噪声能力较高。从上面的分析中可以看到，宽带预编码+子带信道估计优势不明显，因此通常实际系统中，预编码和信道估计同为宽带或子带。
一般来说，如果DMRS发射能量充足(gNB一般满足这一条件)，或者如果DMRS受到复杂(不同频率上的干扰不同)的干扰，子带信道估计的性能不会显著差于宽带，因此在这种情况，一般使用子带预编码；相反，如果DMRS发射能量不足(UE)且干扰单一，子带信道估计性能会过差，甚至消耗掉“子带预编码”的全部增益，因此在这种情况，一般使用宽带预编码。
由上可知，在工厂宏微场景下，宏站下行可以使用子带预编码，而微UE上行可以使用宽带预编码。但如果宏站下行DMRS和微UE上行DMRS在异配比slot上发生碰撞，且两者使用相同的CDM组，则彼此之间会互相干扰。此时，微UE宽带预编码由于受到宏站下行的复杂干扰，已经不再具有性能优势。
下面，介绍本申请的技术方案。
参见图4，图4是本申请提出的一种物理上行共享信道发送的方法的示意性交互图。
S410，终端设备接收网络设备发送的第一DCI。
对应的，网络设备向终端设备发送第一DCI。其中，第一DCI用于调度终端设备在第一时间单元上进行上行传输，以及指示终端设备上行传输所使用的一个或多个天线端口。
作为示例而非限定，本实施例中的网络设备和终端设备分别以工厂宏微场景中的微站和微UE进行举例说明。
可选的，这里的第一时间单元为宏站和微站在同一时隙周期内的异配比时隙。
S420，终端设备根据第一DCI，使用子带预编码或宽带预编码对一个或多个天线端口 中的每一个天线端口中传输的上行数据进行预编码，生成物理上行共享信道PUSCH。
应理解，上行数据包括DMRS。
可选的，在S420之前，所述方法还包括：微站向微UE发送第一高层信令，第一高层信令用于为微UE配置子带预编码的编码参数。使用高层信令(而非物理层信令通知)能够降低物理层DCI的负载，提升系统可靠性。
可选的，第一高层信令分为两部分，第一部分为微UE配置了PRG大小(例如：PRG＝4RB)，第二部分为微UE配置所有PRG上使用的预编码。假设系统总带宽为40MHz(100个RB)，则PRG共有100/4＝25个。第一高层信令的第二部分也就一一对应地分成25个部分，每个部分用来配置对应PRG上的预编码。假设每个预编码使用6bit配置，可选的，每个预编码使用的码本(即6bit信息和子带预编码的对应关系)是微UE和微站事先预定义好的，则第一高层信令的第二部分共占用25*6＝150bit。
可选的，宽带预编码可以和现有标准一样，由第一DCI中的预编码矩阵信息(precoding matrix indicator，PMI)指示域指示。这样微站对微UE预编码的控制更为灵活，微站可以根据调度子帧具体的多用户复用情况，及时更改微UE的预编码，避免多个微UE之间互相干扰，从提升网络的总吞吐量。
需要说明的是，由于微UE在获取第一DCI中的信息之前，需要知道DCI的准确比特数，所以如果宽带预编码对应的DCI中包含了PMI指示域，则子带预编码的DCI中同样要包含该指示域，以保持各种情况下，DCI的长度是一个定值。因此，可选的，为了不浪费子带预编码DCI中的这一指示域。可以在第一高层信令中为微UE配置多套子带预编码，微UE具体用哪套，可以由上述PMI指示域来指示。
可选的，宽带预编码也可以由第一高层信令进行配置。这样，在第一DCI中将彻底不需要指示预编码(即无论是哪种情况，都由第一高层信令配置好了)，从而降低了DCI的负载，提升系统可靠性。
在一种实现方式中，第一DCI还包括子带预编码指示信息，微UE根据子带预编码指示信息，对一个或多个天线端口中的每一个天线端口中传输的上行数据进行预编码。
下面，对于子带预编码指示信息进行举例说明。
举例1：子带预编码指示信息包含1bit的预编码类型指示域，该bit域的值为0或1，分别代表所有天线端口均使用子带预编码或均使用宽带预编码。
举例2：子带预编码指示信息包含N(N≥1)个比特(bit)，其中N是由高层信令配置的上行传输所支持的最大天线端口数。第i(1≤i≤N)个bit的值为0或1，代表第i个天线端口使用子带预编码或使用宽带预编码。对于DCI没有调度到的天线端口，例如DCI仅调度上行传输使用M个天线端口，且M<N，则子带预编码指示信息的前M个比特的值为0或1，代表对应天线端口使用子带预编码或使用宽带预编码；后N-M个比特置零，这样有利于UE判断该DCI是否被正确接收。
在这种实现方式中，UE只需要根据基站的DCI指示信息对每一个天线端口中传输的上行数据进行预编码即可，不需要自己判断需要使用哪种编码预编码类型，基站控制灵活且易于实现，提升了微UE的上行传输性能。
在另一种实现方式中，微UE接收微站发送的第二高层信令，第二高层信令用于为微UE配置CDM组集合，以及第二高层信令用于为微UE确定时间单元集合。
应理解，这里的时间单元集合为宏站和微站的异配比时隙的集合。下面，对于如何通过第二信令确定异配比时隙的集合进行举例说明。
举例1：微站通过和宏站之间的信息交互，获知工厂附近的宏站采用8：2的上下行配比(DDDDDDDDUU)。微站通过第二高层信令，为微UE配置上下行配比2：3(DDUUUDDUUU)，并且通知微UE工厂附近的宏站的上下行配比。微UE根据第二高层信令中宏站和微站上下行配比，确定每10个时隙组成的上下行周期内的异配比时隙的时间单元集合，该时间单元集合包括第3、4、5、8四个时隙，微UE需要在这些时隙集合中根据天线端口判断是否需要使用子带预编码。
举例2：微站通过和宏站之间的信息交互，获知工厂附近的宏站采用8：2的上下行配比(DDDDDDDDUU)。微站通过第二高层信令，为微UE配置上下行配比2：3(DDUUUDDUUU)，并且微站通过第二高层信令，直接为微UE配置每10个时隙组成的上下行周期内的异配比时隙的时间单元集合，该时间单元集合包括第3、4、5、8四个时隙，微UE需要在这些时隙集合中根据天线端口判断自身是否需要使用子带预编码。
需要说明的是，由于微UE上行传输所使用的天线端口可能存在多个，且多个天线端口可能属于不同的CDM组，因此微UE需要先根据天线端口，确定被调度的每个天线端口所属的CDM组，例如：对于一个或多个天线端口中的任意一个天线端口X(即第一天线端口的一例)，记其对应的CDM组为CDM组Y。
具体的，当CDM组Y属于CDM组集合，且第一时间单元属于时间单元集合时，微UE在第一时间单元中使用子带预编码对天线端口X上承载的上行数据进行预编码；当CDM组Y不属于CDM组集合，且第一时间单元属于时间单元集合时，微UE在第一时间单元中使用宽带预编码对天线端口X上承载的上行数据进行预编码。
在同配比的时隙中，即第一时间单元不属于时间单元集合时：
在一种实现方式中，微UE上行传输使用宽带预编码；
在另一种可能的实现方式中，微站为微UE配置第二CDM组集合；当CDM组Y属于第二CDM组集合，且第一时间单元不属于时间单元集合时，微UE在第一时间单元中使用子带预编码对天线端口X上承载的上行数据进行预编码；当CDM组Y不属于第二CDM组集合，且第一时间单元不属于时间单元集合时，微UE在第一时间单元中使用宽带预编码对天线端口X上承载的上行数据进行预编码。
下面对微UE进行上行传输使用不同的天线端口时，如何确定预编码类型进行举例说明。
例如：微站通过测量，和宏站之间的信息交互，获知工厂附近的宏站在天线端口1000和1001以及1004和1005上发送的下行数据，对工厂干扰最大。微站根据标准查得，天线端口1000和1001以及1004和1005分别属于CDM组0、CDM组2。微站通过第二高层信令为微UE配置CDM组集合A，其中，CDM组集合中包括CDM组0、CDM组2。另外，微站还通过第二高层信令为微UE确定异配比时隙集合B。
情况1
假设第一DCI中指示的微UE上行传输所使用的天线端口为1006和1007时，可知微UE使用的天线端口属于CDM组0，即CDM组0属于CDM组集合A。这种情况下，微UE通过异配比时隙集合B判断被调度的第一时间单元是否为异配比时隙，当第一时间单 元为异配比时隙时，微UE在第一时间单元中使用子带预编码对天线端口1006和1007上承载的上行数据进行预编码；否则使用宽带预编码。可选的，微UE可以根据第一DCI中的资源分配指示域，获知微站调度其在RB0～RB19上发送PUSCH，微UE根据第一高层信令中为子带预编码配置的PRG大小和所有PRG上使用的预编码，得到RB0～19属于PRG0～4，进而分别使用PRG0～4对应的子带预编码，对微UE需要发送的上行数据进行预编码，得到PUSCH。
情况2
假设第一DCI中指示的微UE上行传输所使用的天线端口为1008和1009时，微UE确定天线端口1008和1009属于CDM组1，即CDM组1不属于CDM组集合A，因此，微UE在第一时间单元中使用宽带预编码对天线端口1008和1009上承载的上行数据进行预编码，得到PUSCH。
可选的，当第一时间单元不属于时间单元集合时，微UE使用宽带预编码或者由高层信令配置预编码类型(即子带预编码或宽带预编码)。
可选的，第一DCI中还包括相位旋转指示值θ(0≤θ≤π)，微UE根据该相位旋转指示值，将每个PRG中上行DMRS的不同“OCC–RE组”的相位进行旋转。所述“OCC-RE组”，是指一个PRG中的若干个承载着DMRS的RE组成的集合，这里的若干个DMRS被一个相同的OCC序列加权，OCC序列包括时域OCC序列和频域OCC序列，用于联合估计某一端口在该RE组上的信道，并与使用其他OCC序列加权的DMRS在OCC构成的码域正交。参见图5，图5的(a)是一个频域长度为2RB的PRG中，类型1的上行DMRS的不同“OCC-RE组”的相位旋转的示意图，图5的(b)是一个频域长度为2RB的PRG中，类型2的上行DMRS的不同“OCC-RE组”的相位旋转的示意图。具体的，如图5(b)所示，相同填充且连续的4个RE代表一个“OCC-RE组”，第k(k≥0)组“OCC-RE组”，旋转相位2πkθ,即表示在4个RE的发送信号上乘以exp(j2πkθ)，其中j是虚数单位，j 2＝-1。这样使得系统可以支持的最大DMRS端口数成倍增长，例如，为不同的DMRS配置θ＝0、1/3、2/3，可使系统支持的最大DMRS数量增加三倍。
可选的，第一DCI中还包括相位旋转指示值集合Θ＝{θ 0,θ 1,…,θ M-1}，其中包含的M个相位旋转指示值，分别与微UE的M个天线端口一一对应。微UE根据每个天线端口对应的相位旋转指示值，将该天线端口在每个PRG对应的DMRS的不同“OCC–RE组”的相位进行旋转。具体的，如图5的(a)所示，相同填充且时、频域连续的2x个RE代表一个“OCC-RE组”，其中x是发送DMRS的符号个数。又如图5的(b)所示，相同填充且时域连续、频域位于符号4n+i和4n+i+2的2x个RE代表一个“OCC-RE组”，其中i＝0或1，x是发送DMRS的符号个数。第k(k≥0)组“OCC-RE组”上承载的一个天线端口的DMRS，旋转相位2πkθ 0，即表示在2x个RE的发送信号上乘以exp(j2πkθ 0)，其中j是虚数单位，j 2＝-1。这样使得系统可以支持的最大DMRS端口数成倍增长，例如，为不同的DMRS配置θ 0＝0、1/3、2/3，可使系统支持的最大DMRS数量增加三倍。
在这种实现方式中，微站通过隐式指示的方式，指示微UE在不同情况下分别使用子带预编码和宽带预编码，提升了微UE的上行传输性能。
