Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在长期演进(long term evolution，LTE)以及新无线接入技术(new radio access technology)中，多输入多输出(multiple input and multiple output，MIMO)技术被广泛采用。对于小区边缘用户，采用空频块码(space frequency block code，SFBC)传输模式来提高小区边缘信噪比。对于小区中心用户，采用多层并行传输的传输模式来提供较高的数据传输速率。如果基站可以获得全部或者部分下行信道状态信息(channel state information，CSI)的时候，可以采用预编码(precoding)技术来提高信号传输质量或者速率。对于时分复用(time division duplexing，TDD)系统，无线信道的上下行具有互异性，基站接收终端设备发送的探测参考信号(sounding reference signal，SRS)，进行信道估计得到上行CSI，进而根据上下行互异性获得下行CSI。
在现有技术中，SRS在频域呈等间隔梳齿排列，导致可用基底的数量受限，端口复用能力降低。

具体实施方式
为了提高上行信道估计精度，本申请提供一种通信方法。下面将结合附图对本申请作进一步地详细描述。应理解，下面所介绍的方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。
如图1所示，本申请实施例提供的测量反馈方法可应用于无线通信系统，该无线通信系统可以包括终端设备101以及网络设备102。
应理解，以上无线通信系统既可适用于低频场景(sub 6G)，也可适用于高频场景(above6G)。无线通信系统的应用场景包括但不限于第五代系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示终端设备101可以是用户设备(user equipment，UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该终端设备101可具备无线收 发功能，其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信)，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备102。
其中，终端设备101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)设备、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网络中的终端装置或者未来演进的PLMN网络中的终端装置等。
另外，终端设备101可以部署在陆地上，包括室内或室外、手持或车载；终端设备101也可以部署在水面上(如轮船等)；终端设备101还可以部署在空中(例如飞机、气球和卫星上等)。该终端设备101具体可以是手机(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、增强现实(augmented reality，AR)终端、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。终端设备101也可以是具有通信模块的通信芯片，也可以是具有通信功能的车辆，或者车载设备(如车载通信装置，车载通信芯片)等。
网络设备102可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备102具体可包括基站(base station，BS)，或包括基站以及用于控制基站的无线资源管理设备等。该网络设备101还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的芯片。
比如，网络设备102包括但不限于：5G中的下一代基站(g nodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、CRAN系统下的无线控制器、基站控制器(base station controller，BSC)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。网络设备101还可包括未来6G或更新的移动通信系统中的基站。
此外，如图2所示，本申请实施例提供的通信系统可包括至少一个网络设备201。该通信系统200还可以包括至少一个终端设备，例如图2所示的终端设备202至207。其中，该终端设备202至207可以是移动的或固定的。网络设备201和终端设备202至207中的一个或多个均可以通过无线链路通信。每个网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。

下面以图1所示的通信系统为例，说明现有技术中信道探测的方式。
其中，信道探测方式可包括依据上行导频信号(或称上行探测参考信号)进行的上行信道探测，和依据下行导频信号(或称下行探测参考信号)进行的下行信道探测。
典型的下行信道探测基于下行信道状态信息参考信号(channel state information reference signal，CSI-RS)进行，即由终端设备101根据网络设备102发的CSI资源配置对网络设备102发送的CSI-RS信号进行测量，以获得下行信道特征，并由终端设备101根据网络设备102发送的CSI上报配置向网络设备102上报下行信道特征。
上行信道探测一般是基于上行探测参考信号(sounding reference signal，SRS)进行的，即由网络设备102向终端设备101发送SRS配置，由终端设备101根据SRS配置发送SRS，并由网络设备102对终端设备101发送的SRS进行测量，以获得上行信道特征。
在本申请的实施例中，均以SRS作为示例。SRS也可以替换为CSI-RS，或者解调参考信号(demodulation reference resource，DMRS)，或者时域/频域/相位跟踪参考信号等。其中，CSI-RS可以用于获取信道信息从而执行CSI测量上报的已知信号。DMRS可以用于共享信道或者控制信道接收时做信道估计的已知信号。
以下介绍本发明中涉及的名词：
探测参考信号
UE根据预设的已知序列在特定的物理资源上生成SRS并发送，基站侧根据已知序列在该特定的物理资源上通过接收的SRS可以估计得到信道矩阵，用于做上行数据调度或者利用信道互易性做下行数据调度。示例性的，现有技术中采用Zadoff-Chu(ZC)序列生成SRS。SRS可以位于一个时隙中的一个或者多个OFDM符号上，可以占用系统带宽中所有的子载波，也可以采用梳齿形式占用系统带宽中的部分子载波，从而提升网络资源利用率。
SRS在时域上可以是周期性发送的，通常会定义发送周期和偏置，SRS会在周期时域位置上做定期发送。SRS在时域上也可以是非周期性发送的，此时需要DCI信令指示SRS的发送时刻，SRS会在周期时域位置上做瞬时发送。
SRS资源定义了用于发送SRS的时频码域资源。具体的，每个SRS资源会配置如下参数：
SRS资源索引值：当配置了多个SRS资源时，通过索引值区分SRS资源。
SRS端口的数量：通常，SRS端口数量可以为UE的发送天线数量，此时，每个SRS端口对应一个UE发送天线；每个SRS端口可以对应发送天线的一个空域预编码向量，也就是可以对应一个空间波束赋形方式。通常，一个SRS资源上的多个SRS端口的SRS信号占用相同的时频资源，通过码分方式复用。例如，不同SRS端口的SRS信号使用不同的循环移位(cyclic shift，CS)。
SRS占用的时域位置：即时域周期或者偏置的配置信息。
SRS的发送带宽和跳频带宽。
CS值：也叫循环移位值，序列在时域做循环移位的位数。同一个时频资源上，不同SRS信号，或者不同SRS端口可以通过码分复用的正交方式，避免彼此的干扰，该正交方式可以通过循环移位实现。当信道的时延扩展很小时，CS可以基本实现码分正交。接收端通过特定操作可以消除采用其他CS的信号而仅保留采用特定CS的信号，从而实现码分复用。
SRS的发送带宽
SRS的发送带宽是指，SRS的扫描(sounding)带宽，也就是根据SRS做信道估计的频域范围，通过承载SRS的子载波，可以将发送带宽对应的信道估计出来。发送带宽内可能仅有部分子载波上承载了SRS，用于估计出整个发送带宽。后续可将SRS的发送带宽简称为SRS带宽。
进一步的，SRS的发送带宽可以对应同一时刻或者不同时刻上SRS占用的频域资源。例如，当配置了SRS的跳频模式，则SRS需要多个时刻才能扫描完整的发送带宽，其中，每个时刻仅扫描发送带宽中的部分带宽，该部分带宽为跳频带宽。例如，SRS的发送带宽为272RB，且未配置跳频模式，则SRS在一个OFDM符号内占用272个RB；再例如，SRS的发送带宽为272RB，配置跳频模式并且跳频次数为4，则SRS在一个OFDM符号内占用68个RB，即跳频带宽为68个RB，通过4个OFDM符号占用了272RB，OFDM符号之间占用的频域资源不重叠。
系统带宽
指基站和终端设备进行通信时收发信号的频域范围。本申请实施例中的系统带宽可以理解为一个载波(component carrier,CC)，或者，一个部分带宽(bandwidth part，BWP)等，其中，一个CC可以包括多个BWP。
子载波的编号
为了定义子载波的位置，本发明将子载波做了编号，编号(或称频域编号)不同的子载波的频域位置不同。通常，可以将一组子载波按照频率由低到高或者由高到低连续编号。子载波是相对于某一个频域范围编号的。例如，某一个子载波在系统带宽中的编号，或者说，子载波相对于系统带宽的编号是指，将系统带宽中频率最高或者最低的子载波编号记为0，并按照频率由高到低或者由低到高的顺序将系统带宽中的子载波依次编号，从而确定某一个子载波在系统带宽中的编号。
频域起始位置
SRS带宽的频域起始位置，为SRS带宽包含的子载波的编号中的最大值或最小值，编号可以为相对于系统带宽的编号。
跳频带宽的频域起始位置，为跳频带宽包含的子载波的编号中的最大值或最小值，编号可以为相对于系统带宽的编号。
资源单元(resource element，RE)的频域位置
资源单元的频域位置，为资源单元占用的子载波在系统带宽中的编号与SRS带宽的频域起始位置的差值，或，为资源单元占用的子载波在系统带宽中的编号与跳频带宽的频域起始位置的差值。本申请中，可将资源单元占用的子载波的编号简称为资源单元的编号。
目前的SRS发送方案中，SRS在频域呈等间隔梳齿排列，例如图3所示，频域资源为m SRS个RB，梳齿度为K TC，则频域被分为K TC组资源，每组导频数量为
Figure PCTCN2020132968-appb-000049
Figure PCTCN2020132968-appb-000050
为每RB子载波数。
多个端口(端口可以为一个终端设备的一根发射天线，多个端口可以为来自多个终端设备的多根发射天线)在一把梳齿(同样阴影的一组频域资源，即多个端口占用相同的频域资源)上发送SRS信号，通过码分复用。
下面以

个导频资源为对
Figure PCTCN2020132968-appb-000067
个导频资源的K TC梳齿均匀抽取，则F如图4所示，为

个基底完全正交，但是不同组的对应列完全线性相关，例如，F1的第一列和F2的第一列完全线性相关，F 1的第二列和F 2的第二列完全线性相关。所以，在进行多端口复用的时候，仅有
Figure PCTCN2020132968-appb-000072
个基底可用(其他基底与该组基底线性相关，即数学上不可区分)。假设每端口的最大时延扩展为L，则最大复用端口数为

个基均可用。假设每端口的最大时延扩展为L，则最大复用端口数为
Figure PCTCN2020132968-appb-000080
可见，相对于现有技术，频域资源非均匀分布的SRS可以在相同频域资源上复用更多端口
由于
Figure PCTCN2020132968-appb-000081
个基的长度为
Figure PCTCN2020132968-appb-000082
即基的数量大于基的长度，所以
Figure PCTCN2020132968-appb-000083
个基不可能完全正交，即是一组非正交基底。实际上，我们可以设计

本申请实施例提供一种通信方法，用于实现基于非均匀分布的导频资源发送SRS，因此在相同频域资源上复用更多端口，提高端口复用能力。
该通信方法可由第一通信装置或第二通信装置实施。其中，第一通信装置可包括终端设备或终端设备中的部件(比如处理器、电路、芯片或芯片系统等)，这里的终端设备例如图1所示的终端设备101。第二通信装置可包括网络设备或网络设备中的部件(比如处理器、电路、芯片或芯片系统等)，这里的网络设备例如图1所示的网络设备102。
如图5所示，该方法可包括以下步骤：
S101：终端设备和网络设备从第一资源单元集合中确定第二资源单元集合(或者说，确定第一资源单元集合中的第二资源单元集合)，该第二资源单元集合中所有资源单元的频域位置非等间隔分布。
也就是说，在根据第二资源单元集合中的资源单元发送第一信号时，第一信号的频域位置是非等间隔分布的。其中，该第一资源单元集合可包括第一信号带宽范围内的全部资源单元。第二资源单元集合包括根据第一资源单元集合获得的非均匀分布的资源单元的集合，比如，第二资源单元集合为对第一资源单元集合进行非均匀抽取后获得的资源单元的集合。这里的第一信号例如SRS或其他上行参考信号。第一信号带宽可以是第一信号的发送带宽，比如，本申请中，SRS带宽是指SRS的发送带宽。
其中，第一资源单元集合为第一正交频分复用(orthogonal frequency division multiplexing，OFDM)符号属于第一信号的发送带宽的资源单元集合，或者，第一资源单元集合为第一OFDM符号组的所有OFDM符号中的属于第一信号的发送带宽的资源单元集合，第一OFDM符号组包含多个OFDM符号。
以第一信号是SRS为例，第一资源单元集合为第一OFDM符号属于SRS带宽的资源单元集合，或者，所述第一资源单元集合为第一OFDM符号组的所有OFDM符号属于SRS带宽的资源单元集合，所述第一OFDM符号组包含多个OFDM符号。
可选的，第一资源单元集合中的资源单元可分布在第一OFDM符号中，比如图6所示，第一资源单元集合包括第一OFDM符号中的SRS带宽范围内的资源单元，第二资源单元集合可包括第一资源单元集合内的非均匀分布的多个资源单元。图6所示第一资源单元集合的分布方式可称为不跳频方式。
如图6所示，第二资源单元集合中每个资源单元的频域位置分别通过I 0、I 1……I M-1指示，例如，I 0、I 1……I M-1分别指示第二资源单元集合中每个资源单元占用的子载波的编号，或，I 0、I 1……I M-1分别指示第二资源单元集合中每个资源单元占用的子载波的编号与参考子载波的编号的差值，其中，第二资源单元集合中资源单元非均匀分布，或者说，I 0、I 1……I M-1分别指示的资源单元非均匀分布，或者说，I 0、I 1……I M-1非成等差数列。

对于终端设备来说，其可以按照设定的方式根据第一资源单元集合获得非均匀分布的 第二资源单元集合，或者，可以根据来自于网络设备的第二资源单元集合中的资源单元的频域信息确定该第二资源单元集合，该频域信息可指示第二资源单元集合中的资源单元在该第一信号的发送带宽中的相对频域位置，或者指示资源单元在系统中的频域位置。可选的，本申请对于根据第一资源单元集合获得非均匀分布的第二资源单元的方式不做具体限定。

可选的，以上终端设备和网络设备确定的第一序列相同。
示例性的，对于图6来说，可根据I 0、I 1……I M-1分别指示的频域位置确定第一上行端口在第二资源单元集合上发送的第一序列。对于图7来说，可根据

分别指示的频域位置，确定第一上行端口在多个OFDM符号包括的第二资源单元集合上发送的第一序列。
S103：终端设备在第二资源单元集合的所有资源单元上根据第一序列发送第一信号。第一信号包括SRS、CSI-RS、DMRS或其他上行参考信号。
或者说，终端设备在第二资源单元集合的所有资源单元上发送该第一序列或第一序列对应的信号。
S104：网络设备在第二资源单元集合的所有资源单元上根据第一序列接收第一信号。
或者说，网络设备在第二资源单元集合的所有资源单元上接收该第一序列或第一序列对应的信号。
示例性的，以图6为例说明第一序列的发送和接收过程。如图6所示，终端设备可将第一序列映射至M个子载波I 0、I 1……I M-1，生成承载于M个子载波的第一信号，并通过射频发送第一信号，第一信号例如是SRS或其他的上行参考信号。其中，每个子载波可与第一序列的子序列存在映射关系。本申请中，子序列可以是第一序列中的一部分序列。相应地，网络设备根据第一序列接收终端发送承载于子载波I 0、I 1……I M-1的第一信号。
应理解，上述子载波映射的过程或步骤仅仅是示例性的说明，在实际发送第一信号的过程中，可能经过其他处理，本申请不再具体限定。
采用以上方法，终端设备和网络设备可根据第二资源单元集合中每个资源单元的频域位置确定每个上行发送端口在第二资源单元集合上的发送序列，实现非均匀导频资源的SRS的发送和接收，相比于均匀导频资源的SRS发送方案可提高端口复用能力。
一个实施方式中，该方法还可包括S105，所述网络设备根据所述第一信号进行信道估计。可选的，所述网络设备根据所述第一信号进行数据解调。该第一信号在第二资源单元集合的资源单元上根据第一序列发送。
可选的，所述网络设备可以同样先获取第一序列，再根据所述第一序列接收第一信号，为了区分开终端侧发送的第一序列的描述，这里的第一序列可以称为本地第一序列。应理解，获取第一序列的步骤和接收第一信号的步骤可以互换。
作为一个可替换的步骤，所述网络设备可以不获取第一序列，而是存储、生成或确定一个本地序列，在接收第一信号后，根据所述本地序列和第一信号确定出终端侧发送的第一序列。应理解，本地序列可以是多个序列，例如是多个可能被终端确定为第一序列的序列集合。网络设备根据接收到的第一信号，和该多个序列做比对，确认出第一信号为该多 个序列中的一个。应理解，本地序列不一定完全为第一序列，例如可以仅存储第一序列中的前几项，只要能确定出上述终端设备发送的第一信号对应的第一序列即可。
进一步的，在S101和S102的基础上，终端设备还可根据参考子载波的位置指示信息确定第一上行端口的第一序列与第二资源单元集合中的资源单元的映射关系，并根据每个上行端口的第一序列和每个端口的第一序列与资源单元的映射关系，发送第一信号。以第一信号是SRS为例，参考子载波例如SRS带宽的第一个子载波(或其他任一子载波)，该参考子载波的位置指示信息可指示该第一个子载波在系统带宽中的编号。
相应地，网络设备根据第一序列和第一序列与第二资源单元集合中的资源单元的映射关系接收第一上行端口发送的第一信号。
同理，终端设备可采取遍历的方式确定每一个上行端口的发送序列和/或发送序列与第二资源单元集合中的资源单元之间的映射关系，因此当通过多个上行端口进行第一信号的发送时，网络设备可采取类似的方式确定全部上行端口的发送序列和/或发送序列与第二资源单元集合中的资源单元之间的映射关系，以接收全部上行端口发送的第一信号。
下面，分别根据图6和图7所示频域资源的分布方式，对本申请实施例提供的第一信号的发送方法进行说明。其中，图6和图7中以第一信号SRS为例进行说明，第一信号为其他上行参考信号时该第一信号的发送方法可参照实施。

应理解，以上S202至S204所示步骤，也可在不同的第二资源单元集合分别执行，实现多个第一序列和多个第一信号的发送，换句话说，S202至S204所示步骤可在多个第二资源单元集合中分别执行。比如，在S201获得的多个第二资源单元集合的基础上，终端设备和网络设备可从多个第二资源单元集合中，确定出至少两个第二资源单元集合，针对至少两 个第二资源单元集合中的第一个第二资源单元集合，确定第一上行端口在该第一个第二资源单元集合中所有资源单元上的第一序列，进而终端设备根据第一序列在该第一个第二资源单元集合中所有资源单元上发送上行信号，由网络设备根据第一序列在该第一个第二资源单元集合中所有资源单元上接收上行信号；同理，终端设备和网络设备还可针对至少两个第二资源单元集合中的第m个第二资源单元集合，确定第一上行端口(或其他的上行端口)在该第m个第二资源单元集合中所有资源单元上的第一序列，m为正整数，进而终端设备可根据第一序列在该第m个第二资源单元集合中所有资源单元上发送上行信号，由网络设备可根据第一序列在该第m个第二资源单元集合中所有资源单元上接收上行信号。
一个实施方式中，该方法还可包括S205，所述网络设备根据所述第一信号进行信道估计。可选的，所述网络设备根据所述第一信号进行数据解调。该第一信号在第二资源单元集合的资源单元上根据第一序列发送。
可选的，所述网络设备可以同样先获取第一序列，再根据所述第一序列接收第一信号，为了区分开终端侧发送的第一序列的描述，这里的第一序列可以称为本地第一序列。应理解，获取第一序列的步骤和接收第一信号的步骤可以互换。
作为一个可替换的步骤，所述网络设备可以不获取第一序列，而是存储、生成或确定一个本地序列，在接收第一信号后，根据所述本地序列和第一信号确定出终端侧发送的第一序列。应理解，本地序列可以是多个序列，例如是多个可能被终端确定为第一序列的序列集合。网络设备根据接收到的第一信号，和该多个序列做比对，确认出第一信号为该多个序列中的一个。应理解，本地序列不一定完全为第一序列，例如可以仅存储第一序列中的前几项，只要能确定出上述终端设备发送的第一信号对应的第一序列即可。
进一步的，在S201和S202的基础上，终端设备还可根据参考子载波的位置指示信息确定第一上行端口的第一序列与第二资源单元集合中的资源单元的映射关系，并根据每个上行端口的第一序列和每个端口的第一序列与资源的映射关系，发送第一信号。其中，参考子载波例如第二OFDM符号对应的跳频带宽的第一个子载波，该参考子载波的位置指示信息可指示该第一个子载波在系统带宽中的编号。
相应地，网络设备根据第一序列和第一序列与资源单元的映射关系接收第一上行端口发送的第一信号。
同理，终端设备可采取遍历的方式确定每一个上行端口的发送序列和/或发送序列与资源单元之间的映射关系，因此当通过多个上行端口进行第一信号的发送时，网络设备可采取类似的方式确定全部上行端口的发送序列和/或发送序列与资源单元之间的映射关系，以接收全部上行端口发送的第一信号。
下面以第一信号是SRS为例，分别根据图9所示频域资源的分布方式，对本申请实施例提供的第一信号的发送方法进行说明。
如前述，I q,k为第q个第二OFDM符号对应的第二资源单元集合中第k个资源单元的频域位置。也就是说，I q,k用于指示第q个第二OFDM符号对应的第二资源单元集合中第k个资源单元的频域位置。
另外，I q为第q个第二OFDM符号对应的第二资源单元集合中资源单元的频域位置的集合，
