具体实施方式
本申请实施例公开了一种通信方法、装置及计算机可读存储介质，用于消除干扰。以下分别进行详细说明。
为了更好地理解本申请实施例，下面先对本申请实施例的应用场景进行描述。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，可以将网络设备向终端设备发送信息的通信称为下行(downlink，DL)通信，可以将终端设备向网络设备发送信息的通信称为上行(uplink，UL)通信。在第五代无线通信系统，即新无线(new radio，NR)系统中，可以将时域划分为多个无线帧，每个无线帧可以包括多个时隙(slot)，每个时隙可以包括多个符号(symbol)，如正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。无线帧的长度可以为10ms，一个时隙可以包括14个符号。在子载波间隔(subcarrier space，SCS)为15kHz的情况下，一个时隙的时域长度可以为1ms；在SCS为30kHz的情况下，一个时隙的时域长度可以为0.5ms。一个时隙中符号的传输方向可以为DL、UL或者灵活(flexible)。一个时隙中符号的传输方向的组合可以理解为这个时隙的格式(format)。例如，目前NR的TS38.211标准中，规定了若干时隙格式，时隙格式可以如表1所示：
Figure PCTCN2020132543-appb-000001
表1时隙格式
表1中的D表示DL，U表示UL，X表示灵活。具有格式0的时隙可以被称为下行时隙，具有格式1的时隙可以被称为上行时隙。以格式27为例进行说明，格式27表示一个时隙的前3个符号用于DL(或DL传输)，最后3个符号用于UL(或UL传输)，中间的8个符号用于灵活(或灵活传输)。
NR中支持时分双工(time duplexing division，TDD)。网络设备可以通过将上行时隙和下行时隙交替配置在同一载波中来实现TDD。在时域上，上行时隙与下行时隙之间的比例，可以称为TDD上下行配比。例如，8:2是现网中一个非常常见的配比方案，即每10个时隙中包括8个连续的下行时隙，后面接着2个连续的上行时隙。之所以下行时隙数量远大于上行时隙，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，工厂微小区。
在工厂微小区中，每一台机器都有一个高清摄像头对其进行录像监控，判断其是否正常运转。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时隙为主。
请参阅图1，图1是本申请实施例公开的一种以上行业务为主的示意图。如图1所示，包括宏小区和微小区两个小区。宏小区的基站可以称为宏站，微小区的基站可以称为微站。宏站使用常规的下多上少的上下行配比，如图1中室外的DSUDD，S为特殊(special)帧，可以理解为DL帧。微站使用上多下少的上下行配比，如图1中室内的USUUU。这就导致了同一时隙中，对于宏站来说是下行，但对于微站来说是上行，可以称这样的时隙为宏微异配比时隙，简称异配比时隙。宏站在异配比时隙向自己服务的宏用户设备(user equipment，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发送的上行数据的微站所接收到，造成邻区干扰，即跨链路干扰(cross link interference，CLI)。
宏站可以通过令不同发射天线上的信号拥有不同的加权，来实现波束赋形(beamforming)，此时所有天线上的权值组成的向量或矩阵，称为预编码。预编码可以使得发射信号具有一定的指向性。例如，基站所有天线均使用“1”作为对信号的加权，即所有天线的发送信号均相同，则位于“天线阵列的法线方向”的接收端到所有天线的距离均相同。因此，所有天线的发送信号到该接收端的相位均相同，达到通向叠加，信号能量增强的效果，此时，可以称这一特质为发射信号指向该方向，即发射信号指向天线阵列的法线方向。由于在NR中，宏站通常装备有多达192根天线，导致宏站的波束指向性极强，即宏站发出的信号会有一个或多个方向，发射能量都集中在这些方向上。如果微站可以估计这些方向，则可以使用先进接收机得到相比没有这些方向信息时更好的接收解调性能。可以通过估计干扰信道的协方差矩阵来估计方向。因此，如何消除一个接入网设备对处于其覆盖范围内的另一个接入网设备的干扰已成为一个亟待解决的技术问题。
为了更好地理解本申请实施例公开的一种通信方法、装置及计算机可读存储介质，下面先对本申请实施例使用的网络架构进行描述。请参阅图2，图2是本申请实施例公开的一种网络架构示意图。如图2所示，该网络架构至少可以包括网络设备101、网络设备102、终端设备103和终端设备104。网络设备101的覆盖范围，即服务范围为图2中最大的椭圆形所 在区域。网络设备102、终端设备103和终端设备104均处于网络设备101的覆盖范围内。网络设备101可以通过物理下行控制信道(physical downlink control channel，PDCCH)和物理下行共享信道(physical downlink share channel，PDSCH)向终端设备103发送信息。终端设备103可以通过物理上行控制信道(physical uplink control channel，PUCCH)和物理上行共享信道(physical uplink share channel，PUSCH)向网络设备101发送信息。网络设备102的覆盖范围，即服务范围为图2中最小的椭圆形所在区域。终端设备104处于网络设备102的覆盖范围内。网络设备102可以通过PDCCH和PDSCH向终端设备104发送信息。终端设备104可以通过PUCCH和PUSCH向网络设备102发送信息。网络设备101可以通过PDCCH向网络设备102发送信息。例如，当网络设备101向终端设备103发送信号，同时终端设备104向网络设备102发送信号时，由于网络设备102处于网络设备101的覆盖范围内，因此，网络设备102不仅可以接收到来自终端设备104的信号，而且还可以接收到网络设备101向终端设备103发送的信号。
请参阅图3，图3是本申请实施例公开的另一种网络架构示意图。如图3所示，该网络架构至少可以包括网络设备101、终端设备102-104。网络设备101的覆盖范围，即服务范围为图2中的椭圆形所在区域。终端设备102-104均处于网络设备101的覆盖范围内。网络设备101可以通过PDCCH和PDSCH向终端设备102-104发送信息。终端设备102-104可以通过PUCCH和PUSCH向网络设备101发送信息。终端设备102-104之间可以通过侧行链路(sidelink)进行通信。例如，当网络设备101向终端设备102发送信号，同时终端设备104向终端设备103发送信号时，由于终端设备103处于网络设备101的覆盖范围内，因此，终端设备103不仅可以接收到来自终端设备104的信号，而且还可以接收到网络设备101向终端设备102发送的信号。
终端设备，又可以称之为UE、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。终端设备可以为手持终端、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication，MTC)终端，可穿戴设备(例如智能手表、智能手环、计步器等)，车载设备(例如，汽车、自行车、电动车、飞机、船舶、火车、高铁等)、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、智能家居设备(例如，冰箱、电视、空调、电表等)、智能机器人、车间设备、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)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，或智慧家庭(smart home)中的无线终端、飞行设备(例如，智能机器人、热气球、无人机、飞机)或其他可以接入网络的设备。图1中终端设备以UE示出，仅作为示例，并不对终端设备进行限定。UE可以通过建立UE-(R)AN设备-UPF-DN之间的会话，即协议数据单元(protocol data unit，PDU)会话，来访问DN。
网络设备是为终端设备提供无线接入的设备，主要负责空口侧的无线资源管理、服务 质量(quality of service，QoS)流管理、数据压缩和加密等功能。网络设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。网络设备还可以包括无线上网(wireless fidelity，WiFi)接入节点(access point，AP)。网络设备还可以包括全球微波互联接入(worldwide interoperability for microwave access，WiMax)基站(base station，BS)。
需要说明的是，图2和图3所示网络架构中的网络设备或终端设备只是进行示意性说明，并不对网络架构进行限定。例如，通信系统可以包括更多或更少的网络设备或终端设备。
需要说明的是，图2和图3所示的网络设备或终端设备可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。网络设备与终端设备之间可以直接进行通信，也可以通过其他设备或网元进行通信。
为了更好地理解本申请实施例公开的一种通信方法和装置，下面对先对一些概念、用户进行介绍。
为了保证PDCCH上承载信息的安全性，网络设备可以对PDCCH使用RNTI进行加扰。而网络设备可以通过高层信令向不同设备配置不同的RNTI，也可以通过高层信令向同一设备的不同业务配置不同的RNTI。因此，网络设备发送的PDCCH只能被配置了正确RNTI的设备成功接收，从而可以保证网络设备将某些信息发送给固定的设备。
网络设备发送的PDSCH可以包括下行数据以及测量信道所需的参考信号，如解调参考信号(demodulation reference signal，DMRS)。PDSCH支持非常灵活的DMRS位置配置。根据第一个DMRS在PDSCH中所占符号的位置可以将DMRS分为类型(Type)A和B，也可以称为DMRS采用的资源映射TypeA/B。假设第一个DMRS在PDSCH中所占符号的位置为l 0。对于类型A，l 0可以由高层参数dmrs-TypeA-Position配置。对于类型B，l 0＝0，即第一个DMRS符号位于调度的PDSCH的第一个OFDM符号。类型A和B可以如表2所示：
Figure PCTCN2020132543-appb-000002
Figure PCTCN2020132543-appb-000003
表2 DMRS的时域位置表
按DMRS的时域粒度可以将DMRS分为单符号和双符号。单符号DMRS是指时域上的DMRS符号是不连续的。例如，第3、5、8和11四个符号上有DMRS。双符号DMRS在时域上成对出现。例如，占用3、4、9、10四个符号上有DMRS。
按DMRS使用的正交码(orthogonal cover code，OCC)类型(或称为码分复用(code division multiple，CDM)组(group)类型)，可以将DMRS分为配置(configuration)类型1和2。在配置类型1中，单符号最大支持4端口，双符号最大支持8端口。在配置类型2中，单符号最大支持6端口，双符号最大支持12端口。请参阅图4，图4是本申请实施例公开的一种配置类型1和2的示意图。如图4所示，不同填充方格代表不同CDMgroup。配置类型1包括两组CDMgroup。配置类型2包括三组CDMgroup。每个CDMgroup均包括4个天线端口。因此，配置类型1支持8个天线端口，配置类型2支持12个天线端口。
基于上述网络架构，请参阅图5，图5是本申请实施例公开的一种通信方法的流程示意图。如图5所示，该通信方法可以包括以下步骤。
501、网络设备向第一设备发送第一信息。
网络设备可以向第一设备发送第一信息。在一种情况下，网络设备可以通过高层信令向第一设备配置第一信息。在另一种情况下，网络设备可以通过DCI向第一设备发送第一信息。网络设备通过DCI向第一设备发送第一信息，可以理解为通过DCI向第一设备指示第一信息。上述指示可以为显式地指示，也可以为隐式地指示，在此不作限定。
相应地，第一设备接收来自网络设备的第一信息。
第一信息可以包括扰码的信息。
网络设备可以为第一设备配置第一RNTI，即为第一设备配置网络设备与第一设备之间专用的RNTI。网络设备可以通过高层信令向第一设备配置第一RNTI，也可以通过预定义的方式为第一设备配置第一RNTI，还可以通过其它方式向第一设备配置第一RNTI，在此不作限定。
当网络设备需要向第一设备发送DCI时，网络设备可以使用第一RNTI对DCI进行加扰。DCI可以承载在PDCCH上进行传输。
当第一设备为网络设备时，第一设备可以通过高层信令或预定义的方式确定PDCCH的聚合等级。由于网络设备架设高度一般较高，网络设备与网络设备之间的信道一般存在直射路径(即中间无遮挡物)，这使得网络设备之间的信道一般具有较强的信道质量，且随着时间的推移变化不大。因此，可以为在该信道上传输的PDCCH规定较小的聚合等级，不仅可以降低传输资源(对应信道质量好)，而且还可以降低接收端的盲检测次数(对应信道质量变化不大)，从而可以降低接收端的复杂度。
502、网络设备向第二设备发送第一信号。
当有业务需求时，网络设备可以向第二设备发送第一信号。相应地，第二设备可以接 收来自网络设备的第一信号。此外，由于第一设备处于网络设备的覆盖范围内，因此，第一设备也可以接收来自网络设备的第一信号。
在网络设备通过DCI向第一设备发送第一信息的情况下，第一信息还可以包括发送第一信号的天线端口的标识，即包括网络设备用于发送第一信号的天线端口的标识。
在网络设备通过高层信令向第一设备配置第一信息的情况下，网络设备还需要通过DCI向第一设备发送上述天线端口的标识。
在一种情况下，网络设备可以通过高层信令向第一设备配置第一信号的参数。例如，当第一信号为DMRS时，第一信号的参数可以包括资源映射类型(类型A/B)、DMRS的符号位置、DMRS的连续符号位置(单/双符号)、配置类型(类型1/2)等。
在另一种情况下，网络设备可以通过DCI向第一设备发送第一信号的参数，即网络设备向第一设备发送DCI，DCI可以包括第一信号的参数。
第一设备接收到来自网络设备的发送第一信号的天线端口的标识之后，可以先根据发送第一信号的天线端口的标识确定第一信号所属CDM组和第一信号使用的OCC序列，之后可以根据CDM组和OCC序列接收第一信号。
第一设备接收到来自网络设备的第一信号的参数之后，可以根据第一信号的参数先确定第一信号的传输位置，之后可以在传输位置接收第一信号。
举例说明，第一设备接收到来自网络设备的第一信号的参数和发送第一信号的天线端口的标识之后，第一设备可以先根据第一信号的参数确定是图4中上面的图还是下面的图，之后可以根据发送第一信号的天线端口的标识确定在上述确定的图中的具体的位置，即第一信号所属CDM组和第一信号使用的OCC序列。图4中的1000等即天线端口的标识。
503、第一设备根据第一信息确定第一序列。
第一设备接收到来自网络设备的第一信息之后，可以根据第一信息确定第一序列。在第一信息包括扰码的信息的情况下，第一设备可以根据扰码的信息确定第一序列。扰码的信息可以包括一个扰码的信息，也可以包括多个扰码的信息。在扰码的信息包括一个扰码的信息的情况下，第一序列为一个；在扰码的信息为多个扰码的信息的情况下，第一序列为多个。
当网络设备通过DCI向第一设备发送第一信息时，第一设备可以先使用第一RNTI对DCI进行解扰，得到扰码的信息。扰码的信息可以为扰码的身份标识(identity，ID)，也可以为其它可以用于唯一标识扰码的信息。第一序列可以为伪随机序列，也可以为ZC(Zadoff Chu)序列，还可以为其它序列，在此不加限定。
扰码的信息可以为DMRS的扰码的信息，也可以为其它参考信号的扰码的信息，在此不加限定。
为了降低扰码的信息的指示比特，网络设备可以向第一设备配置有扰码的信息的集合。例如，标准中规定终端设备的DMRS扰码的ID为0～65535中的一个数字，即16bit信息。因此，DCI中的每一个终端设备的扰码的信息需要通过16个bit进行通知，如果有10个终端设备的扰码的信息，则DCI至少包括160bit的扰码的信息，过大的信息量不利于DCI的正确传输。因此，网络设备可以根据本小区终端设备的接入情况，为第一设备配置网络设备覆盖范围内终端设备的DMRS扰码的信息的集合。例如，在某一时刻，共64个终端设备接入了网络 设备，等待被网络设备服务，它们的扰码的ID分别为{ID1，ID2，…，ID64}，网络设备可以将这个集合配置给第一设备。当网络设备需要用DCI通知扰码的信息时，可以用集合内元素的序号(共64个，6bit信息)，代替16bit的扰码的信息。以DCI中包含10个终端设备的扰码的信息为例进行说明，DCI中的扰码的信息从160bit降至60bit。可见，可以降低DCI负载，从而可以提高DCI传输可靠性。
504、第一设备根据第一序列和第一信号估计网络设备对第一设备的干扰。
第一设备确定出第一序列，以及接收到第一信号之后，可以根据第一序列和第一信号估计网络设备对第一设备的干扰。第一设备可以先根据第一序列和第一信号进行信道估计。例如，第一设备可以将第一信号通过离散傅里叶变换(discrete fourier transform，DFT)，得到频域信号，将各频点的频域信号除以第一序列的对应元素，得到初步估计信道，最后再通过维纳滤波，滤除信道变化的快变化分量，得到的结果即为信道估计得到的结果。在这样的滤波下，第一设备可以区分第一信号中的能量是来自于网络设备的第一序列还是其他信号。之后第一设备可以根据估计的结果确定第一信号所属子带，具体来说，第一设备可以根据其与网络设备预定义的信道衰落门限，判断第一信号的所属子带。若估计的信道衰落值在某个子带内高于门限值，则第一设备认为第一信号在此子带中发送；相反，若低于门限值，则第一设备认为第一信号未在此子带中发送。最后第一设备可以根据第一信号所属子带对应的干扰确定网络设备对第一设备干扰的空间统计信息。此处的信道衰落值一般是负值。例如，信道衰落门限是-100dB，信道衰落值是-90dB，可见，信道衰落值大于信道衰落门限。在信道衰落值定义为上述信道衰落值的绝对值的情况下，上述“高于”变成“低于”，上述“低于”变成“高于”。例如，信道衰落门限是100dB，信道衰落值是90dB，可见，信道衰落值小于信道衰落门限。干扰的空间统计信息，可以为干扰的协方差矩阵(即二阶矩)，也可以为干扰的三阶矩或其它三阶以上的高阶矩。
由于网络设备一般仅在某些子带中调度终端设备并传输下行数据，因此，对于某个参考信号来说，一般也只是在子带发送。因此，当第一设备在全频带利用该参考信号进行信道估计时，可以明显检测到能量不同的两种信号，通过一个预定义的门限或其他方案，第一设备可以根据能量将这两种信号加以区分。一种能量较高，表示网络设备在该子带发送了参考信号，此时，第一设备可以通过参考信号进行信道估计，计算出该矩阵对应的空间统计信息；另一种能量较低，表示网络设备未在该子带发送参考信号，此时，第一设备不认为该子带上有对第一设备的干扰。
网络设备可以通过DCI对应的每一个参考信号，依照上述方案计算出参考信号所属的子带，以及对应干扰的空间统计信息。之后网络设备可以将这些空间统计信息求和，得到网络设备对第一设备干扰的空间统计信息。
505、第二设备根据第一信号进行信道估计。

603、第一设备根据PMI和第一信号估计网络设备对第一设备的干扰。
第一设备接收到来自网络设备的PMI，以及接收到来自网络设备的第一信号之后，可以根据PMI和第一信号估计网络设备对第一设备的干扰。第一设备可以先根据扰码的信息确定第一序列，之后可以根据第一序列和第一信号进行信道估计，得到第一信号所属子带的子带信道。之后第一设备可以根据第一信号所属子带的子带信道以及第一信号所属子带对应的PMI确定网络设备对第一设备干扰的空间统计信息。第一设备可以先根据第一信号所属子带的子带信道以及第一信号所属子带对应的PMI确定第一信号对应的波束方向，例如，可以将第一信号所属子带的子带信道与第一信号所属子带对应的PMI相乘。之后第一设备可以根据第一信号对应的波束方向确定网络设备对第一设备干扰的空间统计信息。详细描述可以参考步骤504。
604、第二设备根据第一信号进行信道估计。
其中，步骤601-步骤604详细的描述可以参考步骤501-步骤505中相关的描述。
