Description

一种通信方法及通信装置
本申请要求于2022年09月30日提交中国专利局、申请号为202211214461.X、发明名称为“一种通信方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，具体涉及一种通信方法及通信装置。
背景技术
新无线(new radio,NR)中，上行和下行都可采用解调参考信号(demodulation reference signal，DMRS)和相位跟踪参考信号(phase tracking reference signal，PTRS)来完成信道估计、相位噪声估计以及数据解调。其中，DMRS用于信道估计和数据解调，PTRS用于相位噪声的估计。
NR中PTRS和DMRS端口有对应关系。当前，一个DMRS端口对应的PTRS会每两个或四个资源块(resource block，RB)出现一次。在相应RB中，一个DMRS端口对应的PTRS会映射到该DMRS端口对应的RB中的一个资源单元(resource element，RE)上。因此，确定了PTRS所映射的RE的编号，就可以接收或发送PTRS。
目前网络设备和终端设备都可以通过终端设备的无线网络临时标识(radio network temporary identity，RNTI)确定PTRS所映射的RB。但一个RB中RE的数量是固定的，当两个不同DMRS端口对应的PTRS映射在同一RE上时，就会相互干扰，从而影响相位噪声的估计。因此，如何随机化PTRS的干扰成为亟待解决的问题。
发明内容
本申请提供一种通信方法，用于提高PTRS干扰随机化的程度。本申请还提供了相应的通信装置、通信系统、计算机可读存储介质，以及计算机程序产品等。
本申请第一方面提供一种通信方法，该方法可应用于通信装置，包括：获取解调参考信号的端口编号，解调参考信号的端口编号用于确定资源块偏移和资源单元偏移；根据资源块偏移和资源单元偏移确定相位跟踪参考信号的资源单元；根据相位跟踪参考信号的资源单元发送或接收相位跟踪参考信号。
本申请中，通信装置可以为网络设备或终端设备。
本申请中，解调参考信号(demodulation reference signal，DMRS)的端口编号在上行传输中和下行传输中不同。下行传输中DMRS的端口编号从1000开始，如：1000,1001，…，上行传输中DMRS的端口编号从0开始，如：0,1，…。
本申请中，资源块偏移用于指示不同端口编号的DMRS端口对应的PTRS在调度带宽中占用的资源块的位置。
本申请中，资源单元偏移用于表示PTRS在所占用的资源块中占用资源单元的位置，资源单元偏移通常用0，1,2，…，11这12个整数表示。
上述第一方面中，因为通信装置可以基于DMRS的端口编号确定资源块偏移和资源单元偏移，再进一步确定PTRS所映射的资源单元。这样，可以将DMRS的不同端口编号对应的PTRS映射到不同的资源块中，提高了PTRS干扰随机化的程度。
一种可能的实现方式中，该方法还包括：获取终端设备的无线网络临时标识，解调参考信号的端口编号和无线网络临时标识用于确定资源块偏移。
该种可能的实现方式中，可以进一步结合无线网络临时标识确定资源块偏移，从而进一步提高PTRS干扰随机化。
一种可能的实现方式中，该方法还包括：获取资源单元偏移指示信息，解调参考信号的端口编号和资源单元偏移指示信息用于确定资源单元偏移。
该种可能的实现方式中，资源单元偏移指示信息可以用Offset 00、Offset 01、Offset 10和Offset 11表示，同一端口编号对应的不同资源单元偏移指示信息的资源单元偏移不同。通过资源单元偏移指示信息可以进一步提高PTRS干扰随机化。

该种可能的实现方式中，解调参考信号的配置类型通常有两种，分别为DMRS配置类型(DMRS configuration type)1和DMRS配置类型2，在不同配置类型下，DMRS的端口编号与资源单元偏移的对应关系不同。
一种可能的实现方式中，该方法还包括：获取用于传输数据的NRB个资源块，以及相位跟踪参考信号的资源块密度指示信息，NRB为大于1的整数，NRB个资源块的索引为0、1，…，(NRB-1)，资源块密度指示信息用于指示相位跟踪参考信号的资源块密度，NRB和资源块密度用于确定资源块偏移。
该种可能的实现方式中，资源块密度指示信息可以指示资源块密度，资源块密度也可以称为频域密度，资源块密度的取值可以为2或4，也即每两个或四个资源块上出现一次PTRS。需要说明的是资源块密度指示信息指示资源块密度的方式可以是间接指示的，例如，网络设备可以通知终端设备带宽的两个阈值，这两个阈值分别用NRB0和NRB1表示，其中，NRB0＜NRB1，若NRB0≤NRB＜NRB1，则资源块密度的取值为2，若NRB1≤NRB，则资源块密度的取值为4。当然，本申请不限定资源块密度的取值，除了上述所介绍的资源块密度的取值可以为2或4之外，还可以取其他值。需要说明的是，本申请不限定资源块密度的方式的指示方式，可以是上面介绍的间接指示，也可以是其他方式的间接指示，也可以是直接指示资源块密度。

本申请实施例提供一种通信方法，用于提高PTRS干扰随机化的程度。本申请还提供了相应的通信装置、通信系统、计算机可读存储介质，以及计算机程序产品等。以下分别进行详细说明。
本申请实施例的技术方案可以应用于各种通信系统，例如：第五代(5th generation，5G)系统或新无线(new radio，NR)、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)、5G网络之后的移动通信系统(例如，6G移动通信系统)、车联网(vehicle to everything，V2X)通信系统等。
为便于理解，下面先对本申请实施例所提出的通信方法的系统架构和应用场景进行介绍：
本申请实施例提出的方案可以基于新无线技术，又称为5G技术，也可以基于后续演进接入制式，具体此处不做限定。在本实施例以及后续实施例中，以基于5G的通信系统为例进行介绍。如图1所示，该通信系统包括：终端设备101和网络设备102，该终端设备101可以接收网络设备102的配置，并根据网络设备102的配置确定相位跟踪参考信号(phase tracking reference signal，PTRS)的资源单元(resource element，RE)，根据相位跟踪参考信号的资源单元发送或接收相位跟踪参考信号。
在一种实现方式中，该通信方法可以应用于基于5G的车联网(vehicle to everything，V2X)系统中，即通过装载在车上的传感器或车载终端设备等提供车辆信息以实现车辆与其他设备之间的通信的系统。在该车联网系统中，车辆与车辆(vehicle to vehicle，V2V)，车辆与基础设施(vehicle to infrastructure，V2I)，车辆与网络(vehicle to network，V2N)以及车辆与行人(vehicle to pedestrian，V2P)之间均可以通信，当该终端设备101为车联网中的终端时，该终端设备101可以根据网络设备102的配置发送或接收相位跟踪参考信号。
在一种另实现方式中，该通信方法可以应用于基于5G的物联网(internet of things，IoT)系统 中，例如，可以基于窄带物联网(narrowband internet of things，NB-IoT)制式或增强机器类通信(enhanced machine type communication，eMTC)制式，具体此处不做限定。在该系统中，NB-IoT终端或eMTC终端均为低功耗终端设备，可以在低功耗广域网(low-power wide-area network，LPWAN)内进行数据连接，并实现前述低功耗终端设备之间的数据传输或低功耗终端设备与网络设备之间的数据传输。因此，当该终端设备101为NB-IoT终端或eMTC终端时，该终端设备101可以根据网络设备102的配置发送或接收相位跟踪参考信号。
应当理解的是，本申请实施例中的通信方法除了适用于上述场景，还可以适用于其他场景，具体此处不做限定。

在车联网场景下，该终端设备101可以是车联网终端设备，也被称为V2X终端设备。具体地，在V2V通信过程中，该终端设备101可以为车载终端；在V2I通信过程中，该终端设备101可以为车载终端或带有移动通信功能的基础设施；在其他的V2X场景，该终端设备101还可以是其他的V2X设备，具体此处不做限定。该终端设备101还可以是可穿戴设备，如眼镜、手套、手表、服饰及鞋，或者其他的可以直接穿在身上或是整合到用户的衣服或配件的一种便携式设备。

应当理解的是，本申请实施例中的终端设备101可以是上述任意一种场景下的设备或该设备中的芯片，具体此处不做限定。无论作为设备还是作为芯片，该终端设备101都可以作为独立的产品进行制造、销售或者使用。
此外，与前述终端设备101进行通信的网络设备102，可以是无线网络中的设备。例如，网络设备是部署在无线接入网中为终端设备提供无线通信功能的设备。例如，网络设备可以为将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点，又可以称为接入网设备。
网络设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G移动通信系统中的网络设备。例如，新空口(new radio，NR)系统中的下一代基站(next generation NodeB，gNB)，传输接收点(transmission reception point， TRP)，传输点(transmission point，TP)；或者，5G移动通信系统中的基站的一个或一组(包括多个天线面板)天线面板；或者，网络设备还可以为构成gNB或传输点的网络节点。例如，基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)等。
应当理解的是，本申请实施例中的网络设备102可以是上述任意一种设备或该设备中的芯片，具体此处不做限定。无论作为设备还是作为芯片，该网络设备102都可以作为独立的产品进行制造、销售或者使用。
为便于理解，下面以前述图1所示的系统架构为基础，对本申请实施例提供的通信方法进行介绍。
如图2所示，本申请实施例提供的通信方法的一实施例包括：
201.通信装置获取解调参考信号(demodulation reference signal，DMRS)的端口编号，解调参考信号的端口编号用于确定资源块偏移和资源单元偏移。
本申请实施例中，通信装置可以为网络设备或终端设备。
当通信装置为网络设备时，该步骤201可以是网络设备选择解调参考信号的端口编号。
当通信装置为终端设备时，该步骤201可以是终端设备接收网络设备选定的端口编号。
需要说明是，解调参考信号的端口编号在上行传输中和下行传输中不同。下行传输中DMRS的端口编号可以从1000开始，如：1000,1001，…，上行传输中DMRS的端口编号可以从0开始，如：0,1，…。
本申请实施例中，资源块偏移用于指示不同端口编号的DMRS端口对应的PTRS在调度带宽中占用的资源块的位置。
本申请实施例中，资源单元偏移用于表示PTRS在所占用的资源块中占用资源单元的位置，资源单元偏移通常用0，1,2，…，11这12个整数表示。
202.通信装置根据资源块偏移和资源单元偏移确定相位跟踪参考信号的资源单元。
203.通信装置根据相位跟踪参考信号的资源单元发送或接收相位跟踪参考信号。
该步骤203中，若是上行传输，则终端设备在相位跟踪参考信号的资源单元上发送相位跟踪参考信号，网络设备从相位跟踪参考信号的资源单元上接收相位跟踪参考信号。
若是下行传输，则网络设备在相位跟踪参考信号的资源单元上发送相位跟踪参考信号，终端设备从相位跟踪参考信号的资源单元上接收相位跟踪参考信号。
本申请实施例中，因为通信装置可以基于DMRS的端口编号确定资源块偏移和资源单元偏移，再进一步确定PTRS所映射的资源单元。这样，可以将DMRS的不同端口编号对应的PTRS映射到不同的资源块中，提高了PTRS干扰随机化的程度。
本申请实施例中在确定相位跟踪参考信号的资源单元之前，可以确定资源单元偏移和资源块偏移，下面分别进行介绍。
1、确定资源单元偏移。
可选地，本申请实施例中的通信方法中，通信装置还获取资源单元偏移指示信息，可以通过解调参考信号的端口编号和资源单元偏移指示信息确定资源单元偏移。
资源单元偏移指示信息可以用Offset 00、Offset 01、Offset 10和Offset 11表示，同一端口编号对应的不同资源单元偏移指示信息的资源单元偏移不同。
可选地，本申请实施例中的通信方法中，通信装置还获取解调参考信号的配置类型，可以通过解调参考信号的端口编号和解调参考信号的配置类型确定资源单元偏移。
解调参考信号的配置类型通常有两种，分别为DMRS配置类型(DMRS configuration type)1和DMRS配置类型2，在不同配置类型下，DMRS的同一端口编号对应的资源单元偏移不同。
为了便于理解，下面结合表格对解调参考信号的端口编号、解调参考信号的配置类型、资源单元偏移指示信息和资源单元偏移进行说明。
因为下行传输与上行传输中的解调参考信号的端口编号不同，下面先介绍下行传输中的解调参考信号的端口编号、解调参考信号的配置类型、资源单元偏移指示信息和资源单元偏移之间的关系。
下表1为下行传输中端口编号1001-1003在配置类型为第一类型时的相关信息。

表3：
表3中，Offset 00、Offset 01、Offset 10和Offset 11都为资源单元偏移指示信息。1008、1009、1010和1011为下行传输中扩展的四个第一类型的解调参考信号的端口编号。资源单元偏移指示信息和解调参考信号的端口编号相交位置的数值为该端口编号对应的资源单元偏移，如：端口编号1008在Offset 00对应的资源单元偏移为4，端口编号1009在Offset 01对应的资源单元偏移为8。
下表4为下行传输中端口编号1012-1017在配置类型为第二类型时的相关信息。
表4：

表4中，Offset 00、Offset 01、Offset 10和Offset 11都为资源单元偏移指示信息。1012、1013、1014、1015、1016和1017为下行传输中扩展的六个第二类型的解调参考信号的端口编号。资源单元偏移指示信息和解调参考信号的端口编号相交位置的数值为该端口编号对应的资源单元偏移，如：端口编号1012在Offset 00对应的资源单元偏移为6，端口编号1013在Offset 01对应的资源单元偏移为0。
需要说明的是，第一类型或第二类型的扩展的端口编号对应的资源单元偏移不限于上述表3和表4中的数值，扩展的端口编号也可以直接复用原有的端口编号对应资源单元偏移，如表5和表6中所示。
表5：

上述所介绍的方案中，涉及到了扩展的解调参考信号端口和原有的解调参考信号端口，这些端口都有对应的相位跟踪参考信号。为了便于理解，本申请中，扩展的解调参考信号端口所对应的相位跟踪参 考信号称为第一相位跟踪参考信号，原有的解调参考信号端口所对应的相位跟踪参考信号称为第二相位跟踪参考信号。
这样，在下行传输时，第一相位跟踪参考信号为：解调参考信号的配置类型为第一类型，且解调参考信号的端口编号大于或等于1008的端口对应的相位跟踪参考信号，或者，解调参考信号的配置类型为第二类型，且解调参考信号的端口编号大于或等于1012对应的相位跟踪参考信号。第二相位跟踪参考信号为：解调参考信号的配置类型为第一类型，且解调参考信号的端口编号小于1008的端口对应的相位跟踪参考信号，或者，解调参考信号的配置类型为第二类型的解调参考信号的端口编号小于1012的端口对应的相位跟踪参考信号。

以上说明了得到资源单元偏移的方案，下面介绍得到资源块偏移的方案。
2.确定资源块偏移。
可选地，通信装置获取终端设备的无线网络临时标识，解调参考信号的端口编号和无线网络临时标识(radio network temporary identity，RNTI)用于确定资源块偏移。
可选地，该终端设备的无线网络临时标识例如可以包括下列标识中的至少一个：小区无线网络临时标识(cell-radio network temporary identifier，C-RNTI)、随机接入响应临时识别(random access response temporary identifier，RA-RNTI)、临时C-RNTI、传输功率控制临时标识(transmit power control temporary identifier，TPC-RNTI)，本申请实施例对此不作限定。
可选地，通信装置获取用于传输数据的NRB个资源块，以及相位跟踪参考信号的资源块密度指示信息，NRB为大于1的整数，NRB个资源块的索引为0、1，…，(NRB-1)，资源块密度指示信息用于指示相位跟踪参考信号的资源块密度，NRB和资源块密度用于确定资源块偏移。
该种可能的实现方式中，资源块密度指示信息可以指示资源块密度，资源块密度也可以称为频域密度，资源块密度的取值可以为2或4，也即每两个或四个资源块上出现一次PTRS。需要说明的是资源块密度指示信息指示资源块密度的方式可以是间接指示的，例如，下行传输可以通知上行传输带宽的两个阈值，这两个阈值分别用NRB0和NRB1表示，其中，NRB0＜NRB1，若NRB0≤NRB＜NRB1，则资源块密度的取值为2，若NRB1≤NRB，则资源块密度的取值为4。当然，本申请不限定资源块密度的取值，除了上述所 介绍的资源块密度的取值可以为2或4之外，还可以取其他值。需要说明的是，本申请不限定资源块密度的方式的指示方式，可以是上面介绍的间接指示，也可以是其他方式的间接指示，也可以是直接指示资源块密度。
若是NRB＝1，表示只有一个资源块，则资源块偏移为0。
当有多个资源块时，资源块偏移的取值与用于确定相位跟踪参考信号的资源单元的关系式相关。
当采用第一关系式时：资源块偏移包括第一偏移参数和第二偏移参数；第一偏移参数和第二偏移参数用于确定第一相位跟踪参考信号和第二相位跟踪参考信号的资源单元。
上述步骤202包括：通过第一关系式确定第一相位跟踪参考信号或/和第二相位跟踪参考信号的资源单元；第一关系式为：
其中，k为第一相位跟踪参考信号或/和第二相位跟踪参考信号的资源单元的索引，i为自然数，为一个资源块内的子载波个数，KPT-RS为资源块密度，为第一偏移参数，为第二偏移参数，为资源单元偏移；其中，
其中，nRNTI为无线网络临时标识，mod表示取模，NRB为资源块的数量。
其中，若NRB mod KPT-RS＝0，则若NRB mod KPT-RS≠0，则
由以上关系式可以看出，第一偏移参数可以通过资源块的数量NRB、资源块密度KPT-RS，以及无线网络临时标识nRNTI得到。
第二偏移参数可以通过KPT-RS，以及得到。
若KPT-RS＝2，则：
也就是说，KPT-RS＝2时，若若
若KPT-RS＝4，则
也就是说，KPT-RS＝4时，若或1，若或3，
以上，当-1、2或-2时得到的k为第一相位跟踪参考信号的资源单元的索引，也就是扩展的端口编号对应的相位跟踪参考信号的资源单元的索引。
若得到的k为第二相位跟踪参考信号的资源单元的索引，也就是原来的端口编号对应的相位跟踪参考信号的资源单元的索引。
为了便于理解，下面对以上参数取不同值时第一相位跟踪参考信号和第二相位跟踪参考信号对NRB个资源块的占用情况进行介绍：
(1).资源块密度等于2，NRB为奇数时，第二偏移参数为1，其中，第二偏移参数为1表示第一相位跟踪参考信号的资源单元所属的资源块的索引是2M+1，表示第二相位跟踪参考信号的资源单元所属的资源块的索引是2M，M≥0，且M为整数。
