一种资源配置的方法、装置及系统

技术领域
移动通信的迅速发展对小区边缘用户的性能提出了更高要求，在通信系统中，随着移动通信的快速发展，在系统容量，瞬时峰值速率，频谱效率，小区边缘用户吞吐量以及时延等诸多方面有了更高的要求。协作多点(Coordination Multiple Point，CoMP)传输技术无论是在上行还是下行，都可以提高系统性能，是一种用于解决小区间干扰问题并提升小区边缘用户吞吐量的方法，尤其是改善小区边缘的频谱效率。
在CoMP技术中，可能同时有多个传输接收点(multi-transmitting and receiving point，multi-TRP)服务同一个终端设备。在multi-TRP协作时，新无线(new radio，NR)通信系统中，多个TRP可能同时给终端设备发送下行控制信息(downlink control information，DCI)，终端设备可以在多个不同的搜索空间(search space)搜索检测到多个指示物理下行共享信道(physical downlink shared channel，PDSCH)的DCI，类似的，在上行方向上，针对物理上行共享信道(physical uplink shared channel，PUSCH)也可能存在类似的情况。
对物理数据信道(如PDSCH、PUSCH)，以PDSCH为例，通过指示解调物理数据信道的解调参考信号(demodulation reference signal，DMRS)的相关配置参数，使得接收端能够在相应资源位置上接收DMRS，从而实现对相应物理数据信道的解调。Multi-TRP场景下，由于可能存在多个物理数据信道，某一物理数据信道的DMRS与其他物理数据信道的数据在时频资源上可能会重叠，造成干扰和冲突，影响信道估计的性能，因此，如何避免冲突，是需要考虑解决的问题。

具体实施方式
为使本申请解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将以实施例的形式结合附图对本申请的技术方案作进一步详细的描述。所述详细的描述通过使用方框图、流程图和/或示例提出了设备和/或过程的各种实施例。由于这些方框图、 流程图和/或示例包含一个或多个功能和/或操作，所以本领域技术人员将理解可以通过许多硬件、软件、固件或它们的任意组合单独和/或共同实施这些方框图、流程图或示例内的每个功能和/或操作。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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的情况。其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。本申请中的术语“第一”、“第二”、“第三”、“第四”等仅仅是为了区分，并不作为对本申请实施例的限定。
本申请中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。本申请所提及的所有“终端”/“终端设备”，在一些情况下可以是指移动设备，例如移动电话、个人数字助理、手持或膝上型计算机以及具有电信能力的类似设备，有些情况下还可以是穿戴设备或车载设备等，并包括未来5G网络中的终端或者未来演进的PLMN网络中的终端等。这种终端可以包括设备及其相关联的可移除存储模块(例如但不限于:包括订户标识模块(Subscriber Identification Module，简称为SIM)应用、通用订户标识模块(Universal Subscriber Identification Module，简称为USIM)应用或可移除用户标识模块(Removable User Identity Module，简称为R-UIM)应用的通用集成电路卡(Universal Integrated Circuit Card，简称为UICC)))。备选地，这种终端可以包括没有这种模块的设备本身。在其它情况下，术语“终端”/“终端设备”可以是指具有类似能力但是不可携带的设备，例如，台式计算机、机顶盒或网络设备。术语“终端”/“终端设备”还可以是指可端接用户的通信会话的任何硬件或软件组件。此外，“用户终端”、“User Equipment”、“UE”、“站点”、“station”、“STA”、“用户设备”、“用户代理”、“User Agent”、“UA”、“用户装备”、“移动设备”和“设备”等皆是与本文中“终端”/“终端设备”同义的替代术语。为方便描述，本申请中，上面提到的设备统称为终端设备或UE。
本申请中提及的网络设备，是部署在无线接入网中用以为终端设备提供无线通信功能的装置，能够负责调度和配置给UE的下行参考信号等功能。所述网络设备可以包括各种形式的宏基站、微基站、中继站、接入点等等，可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，新空口(New Radio，NR)系统中的传输节点或收发点(transmission reception point，TRP或者TP)或者下一代节点B(generation nodeB，gNB)，无线保真(Wireless-Fidelity，Wi-Fi)的站点、无线回传节点、小站、微站，或未来第五代移动通信(the 5th Generation Mobile Communication，5G)网络中的基站，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站、接入点、车载设备、可穿戴设备以及5G网络中的网络设备或者未来演进的PLMN 网络中的网络设备等，例如，NR系统中传输点(TRP或TP)、NR系统中的基站(gNB)、5G系统中的基站的一个或一组(包括多个天线面板)天线面板等。本申请实施例对此并未特别限定。在采用不同的无线接入技术的系统中，所述网络设备名称可能会有所不同。为方便描述，本申请中，上述为UE提供无线通信功能的装置统称为网络设备。
图1示出了适用于本申请实施例的涉及的一种无线通信系统100示意性框图。该无线通信系统100可以包括第一网络设备110、第二网络设备120，以及位于第一网络设备110和第二网络设备120覆盖范围内的一个或多个终端设备130。该终端设备130可以是移动的或固定的。第一网络设备110和第二网络设备120均可以与终端设备130通过无线空口进行通信。第一网络设备110和第二网络设备120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。
该无线通信系统100可以支持Multi-TRP传输，即至少两个网络设备(传输点)采用协同多点传输方式向终端设备传输下行数据，换句话说，该终端设备130可以在相同载波上与第一网络设备110通信，也可以与第二网络设备120通信，其中，协同多点传输方式可以采用空间分集和/或空间复用等技术实现，本申请对此不做限定。
本申请中的“协作多点传输”包括但不限于联合传输(joint transmission，JT)。JT包括相干JT和非相干JT(non-coherent joint transmission，NCJT)，两者的区别在于NCJT对来自多个协作TP的不同的MIMO数据流分别做波束赋形，相干JT对来自多个协作TP的所有MIMO数据流做联合做波束赋形。
在本申请实施例中，第一网络设备110可以作为服务网络设备，该第二网络设备120可以为协作网络设备；或者，第一网络设备110可以为协作网络设备，第二网络设备120为服务网络设备。
在应用协同多点传输的场景中，该服务网络设备可以向终端设备发送控制信令，该协作网络设备可以向终端设备发送数据；或者，该服务网络设备可以向终端设备发送控制信令，该服务网络设备和该协作网络设备可以同时向该终端设备发送数据，或者，该服务网络设备和该协作网络设备可以同时向终端设备发送控制信令，并且该服务网络设备和该协作网络设备可以同时向该终端设备发送数据。本申请实施例对此并未特别限定。所述服务网络设备和协作网络设备之间以及多个协作网络设备之间可以进行通信，例如进行控制消息的传递。
以第一网络设备110为服务网络设备，第二网络设备120为协作网络设备为例，该第二网络设备120的数量可以是一个或多个，第一网络设备和第二网络设备也可以都为服务网络设备本申请实施例并不限于此。
在NR中，第一网络设备110和第二网络设备120可以分别发送调度物理下行共享信道(Physical Uplink Shared Channel，PDSCH)的下行控制信息(Downlink Control Information，DCI)给UE(如，DCI1和DCI2)，其中DCI1调度PDSCH1给UE，DCI2调度PDCH2给UE，为了保证UE处的信道估计性能，本申请中，PDSCH1对应的DMRS以及PDSCH1占据的符号位置，不能与PDSCH2对应的DMRS以及PDSCH2占据的符号位置产生冲突，也就是说PDSCH1对应的DMRS不会与PDSCH2占用相同的资源，PDSCH2对应的DMRS不会与PDSCH1占用相同的资源，不会造成冲突影响UE处信道估计的性能。应理解，本申请中，所提及的资源，为时频资源，有时域和频域两个维度， 时域上可以是符号symbol、时隙slot等，频域上可以是子载波间隔等。
应理解，在本申请实施例中，UE或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1所示的仅是本申请所涉及的一种网络系统架构的示例，本申请并不局限于此。应理解，图1所示的本申请实施例可适用的联合传输场景，可以是同构网络的联合传输场景，也可以是异构网的联合传输场景，本申请实施例并不对此做限定。
还应理解，图1所示的场景可以是低频场景，也可以是高频场景，本申请实施例并不对此做限定。
可选的，本申请不限于对PDSCH调度的场景，还适用于对物理上行共享信道(Physical Uplink Shared Channel，PDSCH)调度的场景。
可选的，本申请不限于图1所示的多个网络设备的场景，本申请还适用于单网络设备的场景，只要保证为UE调度的多个物理数据信道对应的DMRS与其他物理数据信道不会存在冲突的技术皆属于本申请的范畴。
以下，为了便于理解和说明，作为示例而非限定，对本申请中的方法在通信系统中的执行过程和动作进行说明。
实施例一
为了能够保证了数据接收端处的信道估计性能，网络设备为UE配置满足预定规则的DMRS资源。需要说明的是，本实施例及后续实施例皆以UE与网络设备之间交互进行描述，仅为示例性描述，本申请不限于此，本申请中网络设备的个数不限制为一个或多个，可以应用在single-TPR和/或multi-TRP的场景下。根据本申请的实施例，图2为本申请提供的一种资源配置的方法的第一个实施例的流程图，为了便于方案理解，在描 述时，本实施例及后续实施例皆以UE和网络设备多侧的行为展开，从交互多方的角度进行整体描述，但绝非限定系统中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在系统中每一侧均有改进。
该方法包括：
S101.网络设备确定解调参考信号DMRS的资源配置信息，所述DMRS用于解调物理数据信道；
可选的，所述资源配置信息包括一个或多个，一个资源配置信息中也可以包括一个或多个配置参数。DMRS的资源，可以基于多个资源配置信息确定。
S102.网络设备向UE发送所述资源配置信息，UE接收DMRS的资源配置信息，其中，UE接收到的资源配置信息包括两组或多组；
可以理解的，网络设备可以有一个或多个，无论涉及一个网络设备还是多个网络设备，在UE角度，本申请中UE接收到的资源配置信息包括两组或多组，但两组或多组并非对任一发送端发送的形式限制。
S103.UE根据所述资源配置信息，确定各组所述资源配置信息配置的DMRS资源；其中，两组或多组资源配置信息中，任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集，所述物理数据信道资源对应的物理数据信道由其他组资源配置信息配置的DMRS资源传输的DMRS解调。
可选的，所述物理数据信道包括：物理下行共享信道PDSCH和/或物理上行共享信道PUSCH。
本申请实施例中，网络设备可以为多个，分别向UE发送所述资源配置信息，DMRS资源可以由多个资源配置信息共同决定，同一网络设备发送的针对同一物理数据信道对应的DMRS的资源配置信息为一组，即，组划分为针对物理数据信道的逻辑划分，并非限制实际发送内容按组划分以组为单位发送，所述多个资源配置信息可以由网络设备分次发送或一起发送。网络设备也可以为一个，针对不同的DMRS资源向UE发送所述资源配置信息，DMRS资源可以由多个资源配置信息共同决定，针对同一物理数据信道对应的DMRS的资源配置信息为一组，所述多个资源配置信息可以由网络设备分次发送或一起发送。可以理解，以上针对网络设备为多个或一个的场景，所述多个资源配置信息可以由网络设备通过高层信令，如无线资源控制(radio resource control，RRC)信令、下行控制信息(downlink control information，DCI)、媒体接入控制信元(media access control element，MAC CE)中的至少一种分次发送或一起发送。两组或多组资源配置信息中可选的包括各组共用的参数信息，所述共用的参数信息可以通过高层信令统一发送。可选的，资源配置信息包括以下至少一类参数信息：物理数据信道的映射类型、物理数据信道占用的时间单元数、物理数据信道起始符号、DMRS附加位置的最大个数、前置DMRS的时间单元数目、前置DMRS的位置、DMRS的类型(如type1、type2)。
本申请实施例中，两组或多组资源配置信息中，任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集的配置参考图3所示，图3是本申请提供的不同物理数据信道对应的DMRS配置示意图。参考图3可知，物理数据信道1的DMRS的资源位置与物理数据信道2的资源位置，要么相同，要么PDSCH2的DMRS的资源位置出现在PDSCH1数据信道资源以外的位置，这样任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源就不会存在交集。 可见，可选的实现方式有：
任一组资源配置信息配置的DMRS资源与其他组资源配置信息配置的DMRS资源，在时域上相同。也就是说，不同物理数据信道对应的DMRS资源均在时域上相同，出现在相同的时间单元位置，所述时间单元可以是符号symbol、时隙slot、帧frame等。
任一组资源配置信息配置的DMRS资源包括第一DMRS资源和/或第二DMRS资源，所述第一DMRS资源与其他组资源配置信息配置的DMRS资源，在时域上相同，所述第二DMRS资源与其他组资源配置信息对应的物理数据信道资源在时域上不存在交集。也就是说，任一物理数据信道对应的DMRS资源可以与其他物理数据信道对应的DMRS资源中的部分DMRS资源在时域上相同，或者任一物理数据信道对应的DMRS资源中部分DMRS资源与其他物理数据信道对应的DMRS资源在时域上相同，所述任一物理数据信道对应的DMRS资源中其余DMRS资源的时域位置出现在所述其他物理数据信道占用的时域资源以外的时域资源位置上。
可以理解，对于第一种方式，任一组资源配置信息配置的DMRS资源与其他组资源配置信息配置的DMRS资源在时域上相同，根据现有的规范要求，可以实现已经配置给DMRS的资源不再配置给数据传输，那么任一组资源配置信息配置的DMRS资源就不会与其他组资源配置信息对应的物理数据信道资源存在交集。对于第二种方式，如果任一组资源配置信息配置的DMRS资源包括第一DMRS资源和第二DMRS资源，第一DMRS资源与其他组资源配置信息配置的DMRS资源在时域上相同，根据现有的规范要求，可以实现已经配置给DMRS的资源不再配置给数据传输，第一DMRS资源不会与其他组资源配置信息对应的物理数据信道资源存在交集，第二DMRS资源与其他组资源配置信息对应的物理数据信道资源在时域上不存在交集，可以是第二DMRS资源的位置在其他组资源配置信息配置的DMRS资源之外、以及在其他组资源配置信息对应的物理数据信道资源之外的资源位置。同样，如果任一组资源配置信息配置的DMRS资源包括第一DMRS资源或第二DMRS资源，那么根据以上对第一DMRS资源、第二DMRS资源的限制，其都不会与其他组资源配置信息对应的物理数据信道资源存在交集。
可选的，在多下行控制信息(downlink control information，DCI)指示PDSCH接收，即在多DCI的场景下时，由于可能存在冲突，采用本实施例及后续实施例的技术手段，配置的DMRS资源需满足预定规则。在非多DCI的场景下，可以按照也可以不按照本申请提供的预定规则进行配置。例如按照本发明可能在NR R15基础上引入额外的“DMRS positions”表格，多DCI的场景下时，采用满足本发明的表格。在非多DCI的场景下，采用NR R15现有表格。
本申请实施例的一种资源配置的方法，通过为UE配置满足预定规则的DMRS资源，保证了数据接收端处的信道估计性能。
实施例二
图4为本申请提供的一种资源配置的方法的第二个实施例的流程图。与实施例一的区别在于，该实施例侧重DMRS的资源配置信息基于满足规则的配置参数设置，可以满足配置如实施例一所述的预定规则的DMRS资源。与实施例一相同或类似的内容在本实施例中不再赘述。需要说明的，为了便于方案理解，在描述时，本实施例仍从交互多方的角度进行整体描述，但绝非限定系统中改进在于交互各侧的步骤必须合在一起执行， 本申请提出的技术方案，在系统中每一侧均有改进。
该方法包括：
S201.网络设备确定以下配置参数中的一种或多种：物理数据信道的映射类型、物理数据信道占用的时间单元数、物理数据信道起始符号、DMRS附加位置的最大个数、前置DMRS的时间单元数目、前置DMRS的位置、DMRS的类型。
可选的，本申请网络设备可以为一个或多个，在有多个网络设备时，各网络设备之间可通过协商或者网络统一调配来确定所述配置参数。此外，网络设备可以分次确定所述配置参数，或者一次确定。
S202.网络设备向UE发送指示所确定配置参数的DMRS的资源配置信息，UE接收DMRS的资源配置信息，其中，UE接收到的资源配置信息包括两组或多组；
可选的，网络设备向UE发送的所述资源配置信息包括一个或多个，一个资源配置信息中也可以包括一个或多个所述配置参数。所述资源配置信息有多个时，可以分次发送或一起发送。
S203.UE根据所述资源配置信息，确定各组所述资源配置信息配置的DMRS资源；其中，两组或多组资源配置信息中，任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集，所述物理数据信道资源对应的物理数据信道由其他组资源配置信息配置的DMRS资源传输的DMRS解调。
本申请中，物理数据信道的DMRS包括前置DMRS(front-load DMRS)和附加DMRS(additional DMRS)，front-load DMRS的位置与物理数据信道的映射类型(mapping type)有关。NR中支持两种mapping type，type A和type B。其中，type A的front-load DMRS的位置相对固定，位于固定的某个符号位置，例如位于符号2或者符号3(符号编号从0开始)，可选的，由RRC信令配置具体是符号2，还是符号3。而type B的front-load DMRS与物理数据信道的资源位置相关，位于整个物理数据信道的第一个符号。
而additional DMRS的数目，是由参数“dmrs-AdditionalPosition”确定的，additional DMRS的位置还与物理数据信道占用的符号数有关，即与参数“duration in symbols”有关。additional DMRS的资源位置，还与front-load DMRS的位置有关。可见，additional DMRS的资源配置相较于front-load DMRS需要涉及更多参数。
在一种实现方式中，网络设备可以根据如下表1所示的示意性满足规则设置的配置参数的关系进行配置参数的确定。如表1所示，以针对单符号DMRS的PDSCH为例，DMRS的资源位置，可以根据以下参数中的一种或多种确定(表1只示出部分参数为例进行说明)：物理数据信道的映射类型(mapping type A/B)、物理数据信道占用的时间单元数(时间单元可以是符号或其他，以符号为例，即占用的符号数(Duration in symbols))、DMRS附加位置的最大个数(dmrs-Additional Position)、前置DMRS的时间单元数目(时间单元可以是符号或其他)、前置DMRS的位置、DMRS的类型(如type1、type2，可以用于确定DMRS的分布图样)。以两个网络设备为例，网络设备1要配置物理数据信道1对应的DMRS1，网络设备2要配置物理数据信道2对应的DMRS2，那么网络设备1和网络设备2要确定是mapping type A还是B，mapping type A和mapping type B对于“l 0”的起始符号位置界定不同，例如，type B下从PDSCH实际的开始位置，即PDSCH的第一符号位置作为front-load DMRS的位置l 0，如果PDSCH实际的第一个符号位置是在第5个symbol，那么l 0在第5个symbol，那么表1中type B下，如果Duration  in symbols为6，dmrs-Additional Position为1，可以对应取值“l 0,4”，那么additional DMRS出现在“4”的位置，l 0在第5个symbol，那么“4”的位置是在第9个symbol。而mapping type A下，front-load DMRS的位置“l 0”相对比较固定，由网络侧配置或采用默认设置，位于固定的某个符号位置。
以网络设备1和网络设备2协商确定配置mapping type A为例，网络设备1和网络设备2还需至少协商dmrs-Additional Position。如果网络设备1和网络设备2确定dmrs-Additional Position为2，网络设备1确定Duration in symbols为8，网络设备2确定Duration in symbols为9，那么additional DMRS1和additional DMRS2均出现在“6”的符号位置上。满足任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集，即任一组资源配置信息配置的DMRS资源与其他组资源配置信息配置的DMRS资源，在时域上相同。
或者网络设备1确定Duration in symbols为9，网络设备1确定Duration in symbols为11，那么additional DMRS1出现在“6”的符号位置上，additional DMRS2出现在“6”、“9”的符号位置上。其中在“6”的符号位置上，additional DMRS1和additional DMRS2的资源位置相同。在“9”的符号位置上，出现additional DMRS2，而由于网络设备1确定Duration in symbols为9，从“0”起算，那么网络设备1配置的物理数据信道1从“0”到“8”占用9个symbol，那么在“9”的符号位置上不会出现物理数据信道1。满足任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集，即任一组资源配置信息配置的DMRS资源包括第一DMRS资源和/或第二DMRS资源，所述第一DMRS资源与其他组资源配置信息配置的DMRS资源，在时域上相同，所述第二DMRS资源与其他组资源配置信息对应的物理数据信道资源在时域上不存在交集。
需要说明的是，如果下表中只有“l 0”的位置，那么对应配置的就只有additional DMRS而没有additional DMRS。即，由于PDSCH占用的符号数不多，用additional DMRS进行解调即可满足信道估计的性能。

可见，通过采用表1这种满足特定规则而设置的配置参数关系，能够使得网络设备 在配置相同mapping type和dmrs-AdditionalPosition参数下，无论Duration in symbols如何配置，皆能使得任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集。除了表1中所示的配置参数的关系，类似的，针对双符号DMRS的PDSCH，还可以采用表2所示的配置参数的关系。与表1类似的配置说明，在此不再赘述。

本申请实施例的一种资源配置的方法，基于满足特定规则的配置参数设置，网络设备在进行配置参数选择和协商时考虑具体的配置参数关系，为UE配置满足预定规则的DMRS资源，保证了数据接收端处的信道估计性能。
实施例三
图5为本申请提供的一种资源配置的方法的第三个实施例的流程图。与实施例一、实施例二的区别在于，该实施例侧重配置参数的确定基于配置参数的划分规则。与实施例一、实施例二相同或类似的内容在本实施例中不再赘述。
该方法包括：
S301.网络设备确定配置参数的选定区间，并确定所述选定区间中以下配置参数中的一种或多种：物理数据信道的映射类型、物理数据信道占用的时间单元数、物理数据信道起始符号、DMRS附加位置的最大个数、前置DMRS的时间单元数目、前置DMRS的位置、DMRS的类型。
可选的，本申请网络设备可以为一个或多个，在有多个网络设备时，各网络设备之间可通过协商或者网络统一调配来确定所述选定区间和/或所述配置参数。此外，网络设备可以分次确定所述配置参数，或者一次确定。
S302.网络设备向UE发送指示所确定配置参数的DMRS的资源配置信息，UE接收DMRS的资源配置信息，其中，UE接收到的资源配置信息包括两组或多组；
可选的，网络设备向UE发送的所述资源配置信息包括一个或多个，一个资源配置信息中也可以包括一个或多个所述配置参数。所述资源配置信息有多个时，可以分次发送或一起发送。
S303.UE根据所述资源配置信息，确定各组所述资源配置信息配置的DMRS资源；其中，两组或多组资源配置信息中，任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集，所述物理数据信道资源对应的物理数 据信道由其他组资源配置信息配置的DMRS资源传输的DMRS解调。
图6(a)是本申请提供的一种针对单符号DMRS的PDSCH一种配置参数区间划分的示意图，如图6(a)所示，根据Duration in symbols和/或dmrs-AdditionalPosition划分区间，如图6(a)所示，包括区间1、区间2、区间3、区间4。以多个网络设备为例，UE可能不期望多个网络设备对应的PDSCH位于不同的区间，即配置的多个网络设备对应的PDSCH位于相同的区间，例如PDSCH1的“Duration in symbols”等于9(属于区间1)，PDSCH2的“Duration in symbols”等于10(属于区间2)，相应的，网络设备在进行协商或根据默认设置进行配置时，会现在多个区间中进行选定，确定选定区间，配置的所述配置参数从所述选定区间中确定。如果区间只有一个的情况下，那么该一个区间就是选定区间，配置的所述配置参数从其中确定。可见，区间的划分规则，使得位于同一区间中的各配置参数所对应的DMRS资源位置，能够满足网络设备在配置相同mapping type和dmrs-AdditionalPosition参数下，无论Duration in symbols如何配置，任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集。
类似，除了图6(a)所示的针对单符号DMRS的PDSCH一种配置参数区间划分，类似的，针对双符号DMRS的PDSCH，可以采用图6(b)所示的配置参数区间划分方式。与图6(a)类似的配置说明，在此不再赘述。同样图7(a)和图7(b)分别示出了针对单符号DMRS的PUSCH和双符号DMRS的PUSCH的配置参数区间划分示意图。配置规则与图6(a)类似，在此不再赘述。
本申请实施例中，区间划分有2种方式：1)采用如图6(a)-图7(b)固定的区间划分方法。即，在预置时，区间就固定下来，不可变。2)可变的区间划分方法，区间划分方法取决于信令中“dmrs-AdditionalPosition”的取值，可选的，划分原则为“同一区间内，任何两个PDSCH duration的DMRS location的并集，均为该区间中的某个元素”，具体而言，可选的，
“Dmrs-AdditionalPosition＝0”时，仅有1个区间，包含所有Duration in symbols的取值情况，如图8(a)、图8(b)、图8(c)、图8(d)，图8(a)、图8(b)、图8(c)、图8(d)分别针对单符号DMRS的PDSCH、针对双符号DMRS的PDSCH、针对单符号DMRS的PUSCH、针对双符号DMRS的PUSCH。
“Dmrs-AdditionalPosition＝1”时，以mapping type A下配置为例，划分有：子区间1、2、3、4，如图9(a)所示，那么这种情况下，网络设备选定区间是从多个区间中进行确定，所述多个区间的划分可以有如下几种：
区间1＝[子区间1，子区间2]；区间2＝[子区间3]；区间3＝[子区间4]。
区间1＝[子区间1]；区间2＝[子区间2]；区间3＝[子区间3]；区间4＝[子区间4]。
区间1＝[子区间1，子区间2]；区间2＝[子区间1，子区间3]；区间3＝[子区间1，子区间4]。
区间1＝[子区间1，子区间2]；区间2＝[子区间1，子区间3]；区间3＝[子区间1，子区间2，子区间4]。
“Dmrs-AdditionalPosition＝2”时，以mapping type A下配置为例，划分有：子区间1、2、3、4，如图9(b)所示，那么这种情况下，网络设备选定区间是从多个区间中进行确定，所述多个区间的划分可以有如下几种：
区间1＝[子区间1，子区间2]；区间2＝[子区间3]；区间3＝[子区间4]。
区间1＝[子区间1]；区间2＝[子区间2]；区间3＝[子区间3]；区间4＝[子区间4]。
区间1＝[子区间1，子区间2]；区间2＝[子区间1，子区间3]；区间3＝[子区间1，子区间4]。
“Dmrs-AdditionalPosition＝3”时，以mapping type A下配置为例，划分有：子区间1、2、3、4，如图9(c)所示，那么这种情况下，网络设备选定区间是从多个区间中进行确定，所述多个区间的划分可以有如下几种：
区间1＝[子区间1，子区间2]；区间2＝[子区间3]；区间3＝[子区间4]。
区间1＝[子区间1]；区间2＝[子区间2]；区间3＝[子区间3]；区间4＝[子区间4]。
区间1＝[子区间1，子区间2]；区间2＝[子区间1，子区间3]；区间3＝[子区间1，子区间4]。
图9(a)-图9(c)为针对单符号DMRS的PDSCH的DMRS配置参数划分示意图，类似的，针对双符号DMRS的PDSCH的DMRS配置参数、针对单符号DMRS的PUSCH、针对双符号DMRS的PUSCH也可以采用上述可变的划分方法，在此不再赘述。
需要说明的，对于本实施例中的配置参数取值和划分范围,其均为示意性说明，并非对本申请方案实现时实际取值和划分范围的限定。
本申请实施例的一种资源配置的方法，基于配置参数的划分，网络设备在进行配置参数选择和协商时考虑具体的配置参数关系，为UE配置满足预定规则的DMRS资源，保证了数据接收端处的信道估计性能。
对于实施例一、实施例二、实施例三：
1)在另一种实现方式中，由于mapping type B下l 0的符号位置的不确定性，为避免DMRS与数据信道冲突，可不为UE配置为type B的映射类型。那么在配置时，网络设备配置的映射类型为类型A，即在多个DCI协作场景下，UE不期望PDSCH为mapping type B
2)在又一种实现方式中，由于additional DMRS位置存在多个的可能，且针对不同的配置参数变化较多，为了避免DMRS与数据信道冲突，可不为UE配置additional DMRS的资源，而配置front-load DRMS的资源，即在多个DCI协作场景下，UE不期望被配置additional DMRS，或者UE不期望dmrs-AdditionalPosition大于0。
3)在又一种实现方式中，为UE配置的2个DCI中，“时域资源分配”域(Time domain resource assignment)取值相同；或者为UE配置的2个DCI中，“时域资源分配”域所指示的开始及长度指示(the start and length indicator，SLIV)或者资源映射类型(mapping type)相同；或者为UE配置的“时域资源分配”域所指示的SLIV和资源映射类型相同；或者为UE配置的“时域资源分配”域所指示的SLIV所指示的区间相同。即在多个DCI协作场景下，UE不期望：各个DCI配置的“时域资源分配”域取值不同、“时域资源分配”域所指示的SLIV或者资源映射类型(mapping type)不同、“时域资源分配”域所指示的SLIV和资源映射类型不同、或“时域资源分配”域所指示的SLIV所指示的区间不同。例如，在UE不期望被配置mapping type B(即为UE配置mapping type A)前提下，UE不期望各组配置参数配置的PDSCH duration或PDSCH duration所属区间不同(即为UE配置的各组配置参数所配置的PDSCH duration或PDSCH duration所属区间相同)。再如在各组配置参数均为UE配置mapping type B前提下，UE不期望各组配置参数配置的 PDSCH duration或PDSCH duration所属区间、start symbol of PDSCH不同(即为UE配置的各组配置参数所配置的PDSCH duration或PDSCH duration所属区间、start symbol of PDSCH相同)。
4)在又一种可能实现方式中，UE不期望各组DMRS的配置不同(即为UE配置的各组DMRS的配置相同)，所述配置包括的front-loaded DMRS数目、additional DMRS数目、front-loaded DMRS位置、additional DMRS位置以及DMRS类型(type1&type2)中的至少一种。
5)在又一种可能实现方式中，UE不期望任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源存在交集(即，任一组资源配置信息为UE配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集)。
6)在又一种可能实现方式中，若任一组资源配置信息的DMRS资源与其他组资源配置信息对应的物理数据信道资源存在交集，UE默认为(可以是协议规定的)，其他组资源配置信息对应的物理数据信道在所述交集上没有发送数据或不处理所述交集上的数据。
需要说明的是，多个DCI协作场景，示例性的，可以有两种配置方式：1)显性信令配置最大DCI数目，当最大DCI数目大于1时，即进入多个DCI协作场景；2)隐性信令，通过配置PDCCH-config数目，隐性指示最大DCI数目，PDCCH-config数目大于1，即进入多个DCI协作场景。
可以理解，以上三种实现方式，可以限制在实施例一、实施例二、实施例三的框架下，也可以不限于实施例一、实施例二、实施例三中具体内容的限制。
实施例四：
图10为本申请提供的一种资源配置的方法的第四个实施例的流程图。与实施例一、实施例二、实施例三的区别在于，该实施例不限制网络设备的配置时需考虑配置资源需满足规则，而是基于优先级来进行资源配置的选用，避免资源冲突。与实施例一、实施例二相同或类似的内容在本实施例中不再赘述。为了便于方案理解，在描述时，本实施例及后续实施例皆以UE和网络设备多侧的行为展开，从交互多方的角度进行整体描述，但绝非限定系统中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在系统中每一侧均有改进。可以理解，本实施例中，多资源配置信息对应的DMRS资源之间可以满足也可以不满足实施例一、实施例二、实施例三的预定规则(即所述任一组资源配置信息配置的DMRS资源与其他组资源配置信息对应的物理数据信道资源不存在交集)
该方法包括：

其中，任一组资源配置信息配置的DMRS资源，与其他资源配置信息对应的DMRS 资源之间具有选用优先级。可以理解的，网络设备可以有一个或多个，无论涉及一个网络设备还是多个网络设备，在UE角度，本申请中UE接收到的资源配置信息包括两组或多组，但两组或多组并非对任一发送端发送的形式限制。
S403.UE根据优先级规则，基于所述选用优先级，选定一组资源配置信息对应的DMRS资源为解调物理数据信道的DMRS的资源。
可选的，所述物理数据信道包括：物理下行共享信道PDSCH和/或物理上行共享信道PUSCH。

可选的，步骤S403之前，UE根据所述资源配置信息，确定各组所述资源配置信息配置的DMRS资源存在冲突。即，在多组资源配置信息对应的DMRS资源存在冲突时，UE才需要根据优先级规则进行选择，可以更优化配置。可选的，UE还可以无论多组资源配置信息对应的DMRS资源是否存在冲突，都会根据优先级规则进行选择，减少了处理的复杂度。
具体的，以UE收到2个DCI或与2个DCI相关的配置参数(例如，在RRC或MAC CE等信令中的与DCI有关联的指示信息)为例进行所述优先级的说明，根据DCI的优先级不同，按照优先级选定规则，确定出DCI，再以该确定的DCI的指示或与该DCI相关的信息，确定DMRS的配置，其中，对于被DCI或DCI相关的配置参数指示的“时域资源分配”域、SLIV、资源映射类型，采用哪个DCI或那个DCI相关的配置参数所指示的，可以遵循以下几种示例：
1)在UE收到2个DCI或与2个DCI相关的配置参数时，“时域资源分配”域遵循标识较小的DCI或与该DCI相关的配置参数的指示。遵循标识较小的DCI或与该DCI相关的配置参数的指示，可以体现为根据DCI中特定配置参数的标识，采用2个DCI或与该DCI相关的配置参数中特定配置参数标识较小的那个DCI所对应指示的“时域资源分配”域。所述特定配置参数包括：控制资源集(control resource set，CORESET)/pdcch资源配置(pdcch-config)/搜索空间(search space)/DMRS端口组(DMRS port group)/小区(cell)/小区组(cell group)/传输接收点(TRP)/使能传输块1(transport block，TB1)/使能传输块2(transport block，TB2)。类似的，SLIV和/或资源映射类型遵循标识较小的所述DCI或该DCI相关的配置参数的指示指示。

6)UE收到2个DCI或与2个DCI相关的配置参数时，”时域资源分配”域、SLIV、资源映射类型中的一项或多项遵循主cell/主cell group/主TRP对应的DCI或与该DCI相关的配置参数的指示。其中，主cell对应的小区标识取值为0，主小区组对应的小区组标识取值为0，主TRP对应的传输点标识取值为0。

上述主要从系统各实体之间交互或者实体内部实现流程角度对本申请实施例提供的方案进行了介绍。可以理解的是，各实体，为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对UE、网络设备进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。下面以采用对应各个功能划分各个功能模块为例进行说明。
本申请实施例还提供了一种终端设备。该终端设备可以用于执行图2，图4-图5，图10任一附图中UE所执行的步骤。图11示出了一种简化的终端设备结构示意图。便于理解和图示方便，图11中，终端设备以手机作为例子。如图11所示，终端设备110包括处理器、存储器、射频电路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对终端设备110进行控制，执行软件程序，处理软件程序的数据等。存储器主要用于存储软件程序和数据。射频电路主要用于基带信号与射频信号的转换以及对射频信号的处理。天线主要用于收发电磁波形式的射频信号。输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。需要说明的是，有些种类的终端设备110可以不具有输入输出装置。其中，存储器和处理器可以是集成在一起的，也可以是独立设置的；此外，射频电路和处理器可以是集成在一起的，也可以是独立设置的。
当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备110时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图11中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。

例如，在一种实现方式中，收发单元1101可以用于执行图2的S102中UE接收的操作，和/或本申请中的其他步骤。处理单元1102可以用于执行图2的S103，和/或本申请中的其他步骤。
例如，在一种实现方式中，收发单元1101可以用于执行图4的S202中UE接收的操作，和/或本申请中的其他步骤。处理单元1102可以用于执行图4的S203，和/或本申请中的其他步骤。
