Description

物理下行数据信道PDSCH资源确定方法及相关产品 技术领域
本申请涉及通信处理技术领域，尤其涉及一种物理下行数据信道PDSCH资源确定方法及相关产品。
背景技术
PDSCH(Physical downlink shared channel，物理下行数据信道)，为下行数据信道中的一种，其主要承载下行数据。
PDCCH(Physical downlink control channel，物理下行控制信道)，PDCCH承载调度以及其他控制信息，具体包含资源分配、上行调度许可、功率控制以及上行重传信息等。
现有的网络中对PDSCH资源的确认可能存在用户设备(UE)与基站设备不一致，因此会降低网络性能。
发明内容
本申请实施例公开了一种物理下行数据信道PDSCH资源确定方法及相关产品，通过统一UE与基站设确定PSDCH资源的确认，有效的实现了UE与网络设备之间的一致性，提高了网络性能。
第一方面，提供一种物理下行数据信道PDSCH资源确定方法，所述方法应用于用户设备UE，所述方法包括如下步骤：
若PDSCH由n个物理下行控制信道PDCCH调度且UE检测到n个PDCCH中至少一个PDCCH时，所述PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，所述n个PDCCH资源以及n个PDCCH关联的DMRS资源集合，不用于该PDSCH；
其中，n为大于等于2的整数。
第二方面，提供一种PDSCH资源确定装置，所述装置包括：
处理单元，用于若PDSCH由n个物理下行控制信道PDCCH调度且检测到n个PDCCH中至少一个PDCCH时，所述PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，所述n个PDCCH资源以及n个PDCCH关 联的DMRS资源集合，不用于该PDSCH。
第三方面，提供一种终端，包括处理器、存储器、通信接口，以及一个或多个程序，所述一个或多个程序被存储在所述存储器中，并且被配置由所述处理器执行，所述程序包括用于执行第一方面所述的方法中的步骤的指令。
第四方面，提供了一种计算机可读存储介质，存储用于电子数据交换的计算机程序，其中，所述计算机程序使得计算机执行第一方面所述的方法。
第五方面，提供了一种计算机程序产品，其中，上述计算机程序产品包括存储了计算机程序的非瞬时性计算机可读存储介质，上述计算机程序可操作来使计算机执行如本申请实施例第一方面中所描述的部分或全部步骤。该计算机程序产品可以为一个软件安装包。
第六方面，提供了芯片系统，所述芯片系统包括至少一个处理器，存储器和接口电路，所述存储器、所述收发器和所述至少一个处理器通过线路互联，所述至少一个存储器中存储有计算机程序；所述计算机程序被所述处理器执行时实现第一方面所述的方法。
本申请提供的技术方案在PDSCH由n个PDCCH调度，并且UE能够检测到n个PDCCH调度中至少一个PDCCH时，另外，PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，那么该PDSCH不使用该n个PDCCH资源以及n个PDCCH关联的DMRS资源集合。即PDSCH采用如图2b所示的资源，因为本申请的技术方案无论检测到的n个PDCCH调度中哪一个或哪几个PDCCH，均不使用n个PDCCH资源以及n个PDCCH关联的DMRS资源集合，因此其使用的PDSCH的资源是唯一确定的，即采用如图2b所示的资源，因此不会导致UE与基站设备之间的认知不一致，提高了网络性能。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，表示前后关联对象是一种“或”的关系。
本申请实施例中出现的“多个”是指两个或两个以上。本申请实施例中出现的第一、第二等描述，仅作示意与区分描述对象之用，没有次序之分，也不表示本申请实施例中对设备个数的特别限定，不能构成对本申请实施例的任何限制。本申请实施例中出现的“连接”是指直接连接或者间接连接等各种连接方式，以实现设备间的通信，本申请实施例对此不做任何限定。
本申请实施例的技术方案可以应用于如图1所示的示例通信系统100，该示例通信系统100包括终端110和网络设备120，终端110与网络设备120通信连接。
该示例通信系统100例如可以是：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE系统(LTE-based access to unlicensed spectrum，LTE-U)、免授权频谱上的NR系统(NR-based access tounlicensed spectrum，NR-U)、通用移动通信系统(Universal Mobile  Telecommunication System，UMTS)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例中的终端110可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、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、个人数字助理(personal digital assistant，PDA)、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、中继设备、车载设备、可穿戴设备，未来5G网络中的终端或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端等，本申请实施例对此并不限定。
本申请实施例中的网络设备120可以是用于与终端通信的设备，该网络设备可以是LTE系统中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继设备、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，5G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，还可以为构成gNB或传输点的网络节点，如基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务， 实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。
在如图1所示的通信系统的终端与网络设备之间的PDCCH增强中,在频域上PDCCH重复调度是一种可能的候选方案,如图2a所示，一种可能的PDCCH重复调度如图2a所示，参阅图2a，其中，PDCCH 1和PDCCH2所在的资源属于不同的CORESET(Control resource set，控制资源集合)资源(即分别为CORESET1和CORESET2),且PDCCH 1和PDCCH2属于PDCCH的repetition，也即至少PDCCH1所承载的DCI所调度的PDSCH资源和PDCCH2所承载的DCI所调度的PDSCH资源是相同的。如图2a所示，PDSCH和PDCCH1所在的CORESET资源重叠。
因此，在一种可选的方案中，如果UE仅检测出了PDCCH1，并未检测出了PDCCH2，则UE认为PDCCH1及其关联的DMRS(Demodulation reference signal，解调参考信号)所在的资源是不用于PDSCH，也即图2b所示。
因此，在另一种可选的方案中，如果UE仅检测出了PDCCH2，而并未检测出了PDCCH1，UE就会认为PDSCH采用如图2a所示的资源。
如上可以看到，UE解出的PDCCH状态不同，则会导致UE的认知不同，也即PDSCH所占用的资源不同，从而导致gNB和UE理解的不一致性，降低了网络性能。
参阅图3，图3提供了一种PDSCH资源确定方法，如图3所示的方法可以有如图1所示的通信系统内的终端执行，该终端具体可以为用户设备UE，该UE具体可以包括：智能手机、平板电脑、个人数字助理、智能手表等等具有通信功能的设备，该通信可以为支持多种协议的通信，本申请并不限制UE支持的具体通信协议，该方法如图3所示，包括如下步骤：
步骤S300、若PDSCH由n个PDCCH调度且UE检测到n个PDCCH中至少一个PDCCH时，所述PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，所述n个PDCCH资源以及n个PDCCH关联的DMRS资源集合，不用于该PDSCH。
上述n可以为大于等于2的整数，具体的，n可以为：2、3、4等等。
上述UE检测到n个PDCCH中至少一个PDCCH具体可以包括：
UE检测到n个PDCCH中的一个PDCCH，未检测到n个PDCCH中剩余的PDCCH；
或UE检测到n个PDCCH中的m个PDCCH，未检测到n个PDCCH中剩余的PDCCH(n-m)，其中n取值大于等于2，m大于等于1且小于n。
或UE检测到n个PDCCH中所有的PDCCH。
上述n个PDCCH关联的CORESET资源具体可以包括：
上述n个PDCCH中每个PDCCH均关联CORESET资源，该CORESET资源可以为n个CORESET资源(即一个PDCCH关联一个CORESET资源)。当然在实际应用中，上述n个PDCCH中多个PDCCH也可以关联同一个CORESET资源，例如2个PDCCH关联一个CORESET资源，当然还可以为n个PDCCH关联一个CORESET资源，本申请对n个PDCCH关联的CORESET资源的具体表现形式并不限定。
本申请提供的技术方案在PDSCH由n个PDCCH调度，并且UE能够检测到n个PDCCH调度中至少一个PDCCH时，另外，PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，那么该PDSCH不使用该n个PDCCH资源以及n个PDCCH关联的DMRS资源集合。即PDSCH采用如图2b所示的资源，因为本申请的技术方案无论检测到的n个PDCCH调度中哪一个或哪几个PDCCH均不使用n个PDCCH资源以及n个PDCCH关联的DMRS资源集合，因此其使用的PDSCH的资源是唯一确定的，即采用如图2b所示的资源，因此不会导致UE与基站设备之间的认知不一致，提高了网络性能。
在一种可选的方案中，上述PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠具体可以包括：
PDSCH与n个PDCCH关联的CORESET中的一个CORESET资源重叠，并且所述PDSCH与n个PDCCH关联的CORESET中的剩余CORESET资源不重叠。
或PDSCH与n个PDCCH关联的CORESET资源重叠。即若n个PDCCH关联的CORESET资源为多个CORESET资源，则PDSCH与多个CORESET 资源均重叠。
实施例一
本申请实施例一提供了一种资源确认的方法，该方法可以由如图1所示的通信系统的终端执行，本申请实施例实现的技术场景为：本实施例的n个PDCCH为2个PDCCH，为了描述的方便，这里命名为PDCCH1和PDCCH2，其中，PDCCH 1和PDCCH2所在的资源属于不同的CORESET资源,且PDCCH 1和PDCCH2属于PDCCH的repetition，也即至少PDCCH1所承载的DCI所调度的PDSCH资源和PDCCH2所承载的DCI所调度的PDSCH资源是相同的，PDSCH和PDCCH1所在的CORESET资源重叠，PDSCH并未和PDCCH2所在的CORSET资源重叠。该方法如图4所示，包括如下步骤：
步骤S400、UE检测出PDCCH1，并未检测出PDCCH2；
步骤S401、UE确定PDCCH1及其关联的DMRS所在资源不用于PDSCH。即PDSCH采用如图2b所示的资源。
在一种可选的方案中，上述步骤S400也可以采用其他步骤替换，例如：
步骤S400-1、UE检测出PDCCH2，并未检测出PDCCH1。
或步骤S400-2、UE检测出PDCCH1和PDCCH2。
本申请提供的实施例在PDSCH由2个PDCCH调度，并且UE能够检测到2个PDCCH调度中至少一个PDCCH时，另外，PDSCH与PDCCH1关联的CORESET资源重叠，那么该PDSCH不使用该PDCCH1资源关联的DMRS资源集合。即PDSCH采用如图2b所示的资源，因为本申请的技术方案无论检测到的n个PDCCH调度中哪一个或全部PDCCH均不使用2个PDCCH资源关联的DMRS资源集合，因此其在如实施例一的技术场景下使用的PDSCH的资源是唯一确定的，即采用如图2b所示的资源，因此不会导致UE与基站设备之间的认知不一致，提高了网络性能。
实施例二
本申请实施例二提供了一种资源确认的方法，该方法可以由如图1所示的通信系统的终端执行，本申请实施例实现的技术场景为：本实施例的n个PDCCH为2个PDCCH，为了描述的方便，这里命名为PDCCH1和PDCCH2，其中，PDCCH 1和PDCCH2所在的资源属于不同的CORESET资源,且 PDCCH 1和PDCCH2属于PDCCH的repetition，也即至少PDCCH1所承载的DCI所调度的PDSCH资源和PDCCH2所承载的DCI所调度的PDSCH资源是相同的，PDSCH和PDCCH1所在的CORESET资源重叠，PDSCH和PDCCH2所在的CORSET资源重叠(如图2c所示)。该方法如图5所示，包括如下步骤：
步骤S500、UE检测出PDCCH1，并未检测出PDCCH2。
步骤S501、UE认为PDCCH1及其关联的DMRS所在的资源是不用于PDSCH，且PDCCH2及其关联的DMRS所在的资源也是不用于PDSCH。即PDSCH采用如图2b所示的资源。
在一种可选的实施方式中，上述步骤S500也可以采用上述步骤S400-1或步骤S400-2来替换。
本申请提供的实施例在PDSCH由2个PDCCH调度，并且UE能够检测到2个PDCCH调度中至少一个PDCCH时，另外，PDSCH与PDCCH1关联的CORESET资源重叠，PDSCH与PDCCH2关联的CORESET资源重叠，那么该PDSCH不使用该PDCCH1资源及其关联的DMRS资源集合，也不使用该PDCCH2资源及其关联的DMRS资源集合。即PDSCH采用如图2b所示的资源，因为本申请的技术方案无论检测到的2个PDCCH调度中哪一个或全部PDCCH均不使用2个PDCCH资源及其关联的DMRS资源集合，因此其在如实施例二的技术场景下使用的PDSCH的资源是唯一确定的，即采用如图2b所示的资源，因此不会导致UE与基站设备之间的认知不一致，提高了网络性能。
本申请实施例还提供一种PDSCH资源确定装置，所述装置包括：
处理单元，用于若PDSCH由n个物理下行控制信道PDCCH调度且检测到n个PDCCH中至少一个PDCCH时，所述PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，所述n个PDCCH资源以及n个PDCCH关联的DMRS资源集合，不用于该PDSCH。
本申请提供的PDSCH资源确定装置在PDSCH由n个PDCCH调度，并且UE能够检测到n个PDCCH调度中至少一个PDCCH时，另外，PDSCH与n个PDCCH关联的CORESET资源中至少一个重叠，那么该PDSCH不使用 该n个PDCCH资源以及n个PDCCH关联的DMRS资源集合。即PDSCH采用如图2b所示的资源，因为本申请的技术方案无论检测到的n个PDCCH调度中一个或几个PDCCH，均不使用n个PDCCH资源以及n个PDCCH关联的DMRS资源集合，因此其使用的PDSCH的资源是唯一确定的，即采用如图2b所示的资源，因此不会导致UE与基站设备之间的认知不一致，提高了网络性能。
