Description

数据传输方法及数据传输装置 技术领域
本公开涉及通信技术领域，尤其涉及数据传输方法及数据传输装置。
背景技术
在新无线技术(New Radio，NR)中，为了保证覆盖范围以及抵抗路径损耗，通常需要基于波束(beam)进行数据传输。
基于波束进行数据传输过程中，网络设备(例如基站)通过信令指示传输配置指示(Transmission Configuration Indication，TCI)状态或空间关系信息(spatial relation info)，进而指示终端的接收波束或发送波束。其中，每个TCI状态或每个空间关系信息对应一个参考信号(Reference Signal，RS)标识，该RS既可以是非零功率信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，也可以是同步信号块(Synchronization Signal Block，SSB)，还可以是探测参考信号(Sounding Reference Signal，SRS)。从而通过TCI状态或空间关系信息可以告知终端接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)所使用的接收波束。
相关技术中，网络设备使用一个面板(panel)向用户发送PDCCH，对于PDCCH的TCI状态，由无线资源控制(Radio Resource Control，RRC)信令针对每个控制资源集合(Control Resource Set，CORESET)配置一个TCI状态的list，list上有多个(比如64个)TCI状态。然后通过媒体接入控制(Media Access Control，MAC)信令针对每个CORESET激活RRC信令配置的多个TCI状态中的一个。网络设备在给终端发送PDCCH时，终端则使用MAC激活的TCI状态对应的参考信号的接收波束来接收PDCCH。
然而，网络设备针对一个PDCCH只给终端配置一个TCI状态。当网络设备有多个传输接收点(Transmission Reception Point，TRP)、每个TRP又有一个或多个发送panel，或者网络设备只有一个TRP、该TRP有多个发送panel时，网络设备可以使用多个天线面板(panel)(该多个panel可以来自同一个TRP或不同的TRP)同时向同一个用户终端发送PDCCH。针对用于PDCCH发送的CORESET而言，每个CORESET MAC信令只会相应的激活其RRC信令配置的多个TCI状态中的一个TCI状态，那么终端在接收该CORESET上发送的PDCCH时，就使用MAC激活的这一个TCI状态来确定接收波束，可靠性相对较低。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的数据传输方法可应用于图1所示的无线通信系统100中。参阅图1所示，该无线通信系统100中包括网络设备110和终端120。终端120通过无线资源与网络设备110相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统100仅是进行示意性说明，无线通信系统100中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备110也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、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NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，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(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端120，也可以称为终端设备、用户设备(User Equipment，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，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开中网络设备110与终端120之间基于波束进行数据传输。基于波束进行数据传输过程中，网络设备(例如基站)通过信令指示TCI状态或空间关系信息，进而指示终端的接收波束或发送波束。目前，网络设备使用一个panel向用户发送PDCCH，对于PDCCH的TCI状态，是由RRC信令针对每个CORESET配置一个TCI状态的list，list上有多个(比如64个)TCI状态，然后MAC信令针对每个CORESET激活RRC信令配置的多个TCI状态中的一个。在网络设备给终端发送PDCCH时，终端则使用MAC激活的TCI状态对应的参考信号的接收波束来接收PDCCH。相关技术中，针对一个PDCCH只给终端配置一个TCI状态。
当网络设备有多个TRP、每个TRP又有一个或多个发送panel，或者网络设备只有一个TRP、该TRP有多个发送panel时，网络设备可以使用多个panel(该多个panel可以来自同一个TRP或不同的TRP)同时向同一个终端发送PDCCH。这种情况下，不同panel的波束发送方向不一样，所以终端也需要使用不同的panel来接收PDCCH。网络设备需要指示不同的TCI状态给用户终端，每个TCI状态对应终端的每个panel上的一个波束方向。
当信令给出type D的TCI状态标识时，指示终端接收该PDCCH时，使用接收该TCI状态标识对应的RS时使用的接收波束(如表1所述)。
表1
Figure PCTCN2020075404-appb-000001
相关技术中，网络设备在给终端配置CORESET时，可以配置一个控制资源池标识 (CORESET pool index)，其中，来自同一个TRP/panel的CORESET对应的CORESET pool index是一样的。网络设备还会为终端配置一个控制资源集合标识(CORESET ID)，以及CORESET占用的时域(时域只配置了符号数，起始符号位置由搜索空间(search space)确定)和频域位置，再加上MAC激活的TCI状态即空域资源的波束方向。
然而，相关技术中针对一个波束方向上发送下行控制信令的方式，数据传输可靠性比较低。
有鉴于此，本公开实施例提供一种数据传输方法，在该数据传输方法中在多个波束方向上采用相同的时域资源发送同一下行控制信令，实现在多个波束方向上(多个TRP/panel)重复发送同一下行控制信令(PDCCH上的DCI信令)，以提高下行控制信令传输的可靠性。
一种实施方式中，本公开实施例可以通过多个不同的频域资源，在多个波束方向上采用相同的时域资源发送同一下行控制信令。另一种实施方式中，本公开实施例也可以通过多个时域资源相同且频域资源相同的传输资源，在多个波束方向上发送同一下行控制信令。
本公开实施例首先对通过多个不同的频域资源，在多个波束方向上采用相同的时域资源发送同一下行控制信令的方式进行说明。
图2是根据一示例性实施例示出的一种数据传输方法的流程图，如图2所示，数据传输方法用于网络设备中，包括以下步骤。
在步骤S11中，配置多个不同的频域资源，并为多个不同的频域资源配置相同的时域资源。
在步骤S12中，通过多个不同的频域资源，在多个波束方向上采用相同的时域资源发送同一下行控制信令。
本公开实施例中，网络设备为终端配置多个不同的频域资源，并通过该多个不同的频域资源，在多个波束方向上采用相同的时域资源发送同一下行控制信令，实现了多个TRP/panel重复发送一个下行控制信令，提高下行控制信令传输的可靠性。
图3是根据一示例性实施例示出的一种数据传输方法的流程图，如图3所示，数据传输方法用于终端中，包括以下步骤。
在步骤S21中，确定多个不同的频域资源以及为多个不同的频域资源配置的相同时域资源。
在步骤S22中，通过多个不同的频域资源，在多个波束方向上采用相同的时域资源接收同一下行控制信令。
本公开实施例中，终端确定网络设备为终端配置的多个不同的频域资源，并通过该多 个不同的频域资源，在多个波束方向上采用相同的时域资源接收同一下行控制信令，实现了多个TRP/panel重复接收一个下行控制信令，提高下行控制信令传输的可靠性。
本公开实施例以下将结合实际应用对上述实施例涉及的多个不同频域资源的配置方式进行说明。
一种实施方式中，本公开实施例中，配置一个CORESET，该CORESET对应的频域资源分配给多个TRP/panel，不同的频域资源对应不同TRP/panel，不同TRP/panel对应不同的波束方向。
相关技术中，针对一个CORESET配置的CORESET pool index取值只能为0或1，分别对应TRP/panel#0和TRP/panel#1。换言之，已有CORESET pool index取值为0或1的CORESET对应一个TRP/panel，即对应一个波束方向。本公开实施例中，为了表征本公开实施例中对应不同TRP/panel的同一CORESET，本公开实施例还可以为该对应多个不同TRP/panel的CORESET配置新的CORESET pool index。该新的CORESET pool index与已有的CORESET pool index取值不同。例如，配置一个CORESET，且该CORESET对应CORESET pool index对应0和1以外的值(例如配置CORESET pool index取值为2或3时表示这个CORESET对应多个TRP/panel)。
为描述方便，本公开实施例中有时将配置的新的CORESET pool index称为第一CORESET pool index。第一CORESET pool index用于表示该CORESET能被配置多个波束方向，也可以理解为是第一CORESET pool index指示的CORESET能被配置给多个TRP/panel。本公开实施例中有时将传统CORESET pool index称为第二CORESET pool index。第二CORESET pool index用于表示该CORESET能被配置一个波束方向，也可以理解为是第二CORESET pool index指示的CORESET能被配置给一个TRP/panel。
本公开实施例中为实现将一个CORESET对应频域资源分配给多个TRP/panel，一种实施方式中，将同一CORESET对应频域资源划分为多个不同RB集合，不同的RB集合对应不同的频域资源，不同的频域资源对应不同的TRP/panel，不同TRP/panel对应不同的波束方向。即，本公开实施例中用于同时传输同一下行控制信令的多个不同频域资源为同一CORESET对应频域资源划分的多个不同RB集合。
本公开实施例中，同一CORESET对应频域资源划分得到的多个不同RB集合中的RB可以是连续的，也可以是不连续的。其中，划分得到的多个不同RB集合中的RB集合中RB数量可以是相同的。其中，本公开实施例中同一CORESET对应频域资源划分的RB集合的数量可以依据波束方向数量确定。以频域资源数量对应在TRP/panel#0和TRP/panel#1两个TRP/panel传输同一下行控制信令为例，同一CORESET对应频域资源分成两半，一 半给TRP/panel#0使用，另一半给TRP/panel#1使用。而该CORESET对应频域资源分成的两半，可以是分成两个连续的RB集合，比如有2N个RB，前面编号为RB#0到RB#(N-1)的RB分给TRP/panel#0使用，后面编号为RB#N到RB#(2N-1)的RB分给TRP/panel#1使用；也可以是分成交织的两个不连续的RB集合，比如有2N个RB，编号为RB#0，RB#2，RB#4……RB#(2N-2)的RB分给TRP/panel#0使用，编号为RB#1，RB#3，RB#5……RB#(2N-1)的RB分给TRP/panel#1使用。
本公开实施例中，多个不同RB集合中的RB连续，使得多个波束方向对应的多个频域资源划分更为简单。多个不同RB集合中的RB不连续，使得频域选择性能更好。
另一种实施方式中，本公开实施例中为实现将一个CORESET对应频域资源分配给多个TRP/panel、分别对应多个TRP/panel的波束方向，可以将配置的这个CORESET对应频域资源分配给一个TRP/panel，而针对其他TRP/panel的频域资源可以是该CORESET对应频域资源加上指定偏移量之后得到的对应的频域资源。即，多个不同频域资源与控制资源集合对应的频域资源具有指定偏移量，多个不同频域资源为与指定控制资源集合对应频域资源具有指定偏移量的多个频域资源。例如，仍以TRP/panel#0和TRP/panel#1两个TRP/panel为例进行说明。配置的CORESET对应频域资源分配给TRP/panel#0(或TRP/panel#1)使用，而另一个TRP/panel的频域资源为这个频域资源加上一个offset偏移量。其中，本公开实施例中与指定控制资源集合对应频域资源具有指定偏移量的多个频域资源的RB数一样，只是位置有偏移。
本公开实施例中以上通过配置一个CORESET实现多个不同频域资源配置的方法中，同样的CORESET pool index和CORESET ID的CORESET相当于是对应多个不同的TRP/panel。即不同TRP/panel上的CORESET的频域资源是由CORESET pool index和CORESET ID相同的一个CORESET对应的频域资源进行划分或者偏移得到的多个频域资源。
本公开实施例中配置了CORESET后需要基于RRC信令和MAC信令，指示多个波束方向的TCI状态。采用上述配置一个CORESET实现多个不同频域资源配置的方式，对于TCI状态，RRC信令可以指示一个CORESET的TCI状态list，MAC信令激活RRC信令指示的TCI状态列表中的一个或多个TCI状态。
其中，同一CORESET对应的多个频域资源不同，但是为了保证在相同的时域资源上发送，所以同一CORESET对应的多个频域资源中各频域资源具有至少一个相同的配置参数。配置参数包括以下的至少一种：时域符号数、search space周期、search space的时隙偏移量、search space的时隙内监测的起始符号位置。例如同一CORESET对应的多个频域 资源中各频域资源对应的时域符号数相同，同一CORESET对应的多个频域资源中各频域资源对应的search space的周期和时隙偏移量相同，以及同一CORESET对应的多个频域资源中各频域资源对应的search space的时隙内监测的起始符号位置相同。
本公开实施例中，配置一个CORESET实现多个不同频域资源配置的方式，RRC信令可以联合配置其不同频域资源对应的不同TRP/panel的TCI状态，其实也是一个RRC信令对应配置一个CORESET的TCI状态list。同样，MAC信令也是对应激活一个CORESET的TCI状态，但是不是只激活一个，可以激活一个或多个。其中，MAC信令激活的TCI状态数量小于或等于划分或偏移后得到的频域资源数量。比如针对每个TRP/panel激活的TCI状态数量为0个或1个。那么终端在接收这个CORESET上的PDCCH时，必须使用MAC CE激活的所有TCI状态对应的接收波束来接收该PDCCH。
本公开实施例中为描述方便，将配置一个CORESET实现多个不同频域资源配置的方式中指示TCI状态的RRC信令称为第一RRC信令，激活TCI状态的MAC信令称为第一MAC信令。第一RRC信令用于指示CORESET的TCI状态列表，第一MAC信令用于激活TCI状态列表中的一个或多个TCI状态。
本公开实施例中，针对不同的TRP/panel实现基于不同的频域资源进行PDCCH上下行控制信令的重复发送，也可以配置多个CORESET，多个CORESET对应的CORESET pool index不同。即，在多个波束方向上传输同一下行控制信令的多个不同频域资源为具有不同CORESET pool index且频域资源不同的多个CORESET对应的频域资源。
其中，多个CORESET对应的频域资源不同，但是CORESET ID可以相同或不同。但为了保证在相同的时域资源上发送，所以多个CORESET具有至少一个相同的配置参数，所述配置参数包括以下的至少一种：时域符号数、搜索空间周期、search space的时隙偏移量、search space的时隙内监测的起始符号位置。例如，多个CORESET对应的时域符号数相同，多个CORESET对应的search space的周期和时隙偏移量相同，多个CORESET对应的search space的时隙内监测的起始符号位置相同。
本公开实施例中，配置多个独立的CORESET实现多个不同频域资源配置的方式，多个CORESET的TCI状态独立配置，即RRC信令分别指示各个CORESET的TCI状态列表。MAC信令可以独立激活不同TCI状态列表中的TCI状态，也可以联合激活多个TCI状态列表中的TCI状态。本公开实施例中为描述方便，将配置多个独立的CORESET实现多个不同频域资源配置的方式中指示TCI状态的RRC信令称为第二RRC信令，MAC信令称为第二MAC信令。其中，第二RRC信令与配置的CORESET数量相同，用于分别指示具有不同CORESET pool index的多个CORESET的TCI状态列表。第二MAC信令的数 量为一个或多个，一个或多个第二MAC信令用于激活TCI状态，其中，激活的TCI状态数量小于或等于频域资源数量。一示例中，仍以TRP/panel#0和TRP/panel#1两个TRP/panel为例进行说明。如果是需要多个第二MAC信令，那么每个第二MAC信令用于激活其中一个TRP/panel的TCI状态。这种情况下每个第二MAC信令激活的TCI状态为0或1，即针对每个TRP/panel，可以激活0个TCI状态即不激活或激活1个TCI状态。如果是需要一个第二MAC信令，那么这一个第二MAC信令用于激活两个TRP/panel的TCI状态。这种情况下，这一个第二MAC信令激活的TCI状态为1或2，即激活其中一个TRP/panel的TCI状态，或针对两个TRP/panel分别激活一个TCI状态。
可以理解的是，本公开实施例中，第二MAC信令只激活了一个TCI状态时，数据传输并不是多个TRP/panel重复传输同一下行控制信令了，而是回退到一个TRP/panel来发送下行控制信令了。
本公开上述实施例中，通过配置多个不同频域资源的方式实现同一下行控制信令在多个波束方向上传输的方式中，多个波束方向对应相同的小区标识，或对应不同的小区标识，即，多个TRP/panel可以是intra-cell或intel-cell，以适用不同的通信场景需求。其中，如果多个TRP/panel是inter-cell，那么上述配置多个CORESET的方式中，CORESET pool index不一样，还可以是CORESET对应的CORESET pool index和/或小区索引不一样。
进一步的，本公开实施例中，网络设备可以向终端发送第一指示信息，其中，第一指示信息用于指示终端通过多个不同的频域资源同时接收多个波束方向的同一下行控制信令。终端接收到网络设备发送的第一指示信息，在多个不同的频域资源同时接收多个波束方向的同一下行控制信令。其中，上述第一指示信息可以是RRC信令和/或MAC信令。该RRC和/或MAC信令可能包含小区索引和/或CORESET pool index和/或CORESET ID。通过第一指示信息指示的方式，可以确定开始启动下行控制信令重复发送的方法。
进一步的，本公开实施例中通过多个不同的频域资源，在多个波束方向上采用相同的时域资源发送同一下行控制信令时，该下行控制信令的时隙位置并不限定。例如，下行控制信令的时隙位置可以是在时隙(slot)的起始符号位置，即占用符号0，1，2。下行控制信令的时隙位置也可以在slot的中间位置，比如针对mini-slot的调度。
本公开实施例中通过设计新的CORESET的配置方法，包括RRC信令中的CORESET pool index，以及TCI状态配置相关的RRC信令和激活TCI状态相关的MAC信令的配置，使得终端能够接收来自多个TRP/panel在不同频域资源上发送的同样的下行控制信令。并且多个TRP/panel可以是来自同一个小区，也可以是来自不同小区。通过本公开使得PDCCH的下行控制信令通过不同的波束方向在不同频域资源上重复发送，从而提高下行 控制信令传输的可靠性和鲁棒性。
可以理解的是，本公开实施例上述通过多个TRP/panel使用不同的频域资源重复发送同一下行控制信令的实施方式适用于终端和网络设备交互过程。
本公开实施例以下对通过时域资源相同且频域资源相同的多个传输资源，在多个波束方向上发送同一下行控制信令的实施过程进行说明。
其中，可以理解的是，本公开实施例中以下为描述方便，将时域资源和频域资源简称为时频资源。时频资源相同表示时域资源相同且频域资源相同。本公开实施例中，时域资源相同且频域资源相同的多个传输资源，有时也称为多个时频资源相同的传输资源。本领域人员应理解其含义的一致性。
图4是根据一示例性实施例示出的一种数据传输方法的流程图，如图4所示，数据传输方法用于网络设备中，包括以下步骤。
在步骤S31中，配置多个传输资源，多个传输资源中各传输资源的时域资源相同且频域资源相同。
在步骤S32中，通过多个传输资源，在多个波束方向上发送同一下行控制信令。
本公开实施例中，网络设备为终端配置多个时频资源相同的传输资源，并通过该多个时频资源相同的传输资源，在多个波束方向上发送同一下行控制信令，实现了多个TRP/panel重复发送一个下行控制信令，提高了下行控制信令传输的可靠性。
图5是根据一示例性实施例示出的一种数据传输方法的流程图，如图5所示，数据传输方法用于终端中，包括以下步骤。
在步骤S41中，确定多个传输资源，多个传输资源中各传输资源的时域资源相同且频域资源相同。
在步骤S42中，通过多个传输资源，在多个波束方向上接收同一下行控制信令。
本公开实施例中，终端确定网络设备为终端配置的多个时频资源相同的传输资源，并通过该多个时频资源相同的传输资源，在多个波束方向上接收同一下行控制信令，实现了接收多个TRP/panel重复发送的一个下行控制信令，提高了下行控制信令传输的可靠性。
本公开实施例中，网络设备通过多个时频资源相同的传输资源，在多个波束方向上发送同一下行控制信令，可以理解为是多个TRP/panel在同样的时频域资源上使用不同的波束方向给同一终端发送同一下行控制信令，那么多个TRP/panel使用的发送波束不同。而终端通过该多个时频资源相同的传输资源，在多个波束方向上接收同一下行控制信令的接收波束也不同，即终端同时使用多个TCI状态对应的接收波束来接收来自多个TRP/panel的PDCCH上发送的同一下行控制信令。
本公开实施例中，针对不同的TRP/panel实现基于多个时频资源相同的传输资源重复发送同一下行控制信令，也可以配置多个时频资源相同的CORESET，多个CORESET对应的CORESET pool index不同。即，在多个波束方向上传输同一下行控制信令的多个时频资源相同的传输资源为时频资源相同并且具有不同CORESET pool index的多个CORESET对应的时频资源。
其中，多个时频资源相同的CORESET对应的CORESET ID可以相同也可以不同。
本公开实施例中针对CORESET pool index不同，但是时频资源相同的多个CORESET，可以当作多个独立的CORESET，分别独立配置TCI状态。即，RRC信令分别配置各个CORESET的TCI状态列表。MAC信令分别激活其中一个TCI状态。本公开实施例中为描述方便，将配置多个独立的CORESET实现多个时频资源相同的传输资源配置的方式中指示TCI状态的RRC信令称为第三RRC信令，MAC信令称为第三MAC信令。其中，第三RRC信令分别指示每一CORESET的TCI状态列表。第三MAC信令用于分别指示或联合指示第三RRC信令指示的各TCI状态列表中激活的TCI状态。
本公开实施例中，第三MAC信令分别指示第三RRC信令指示的各TCI状态列表中激活的TCI状态时，激活的TCI状态数目小于或等于一个。其中，第三MAC信令联合指示多个第三RRC信令指示的各TCI状态列表中激活的TCI状态时，激活的TCI状态数目小于或等于配置的CORESET的数目。
一示例中，由于时频资源相同，所以终端无法区分是哪个CORESET pool index对应的TRP/panel发送过来的下行控制信令，故，针对任一个CORESET pool index的CORESET，只要MAC激活了一个TCI状态，终端就需要使用这个TCI状态去接收这个CORESET时频资源上发送的下行控制信令。如果多个CORESET pool index的CORESET，第三MAC信令都分别或联合激活了TCI状态，那么终端就需要针对多个CORESET pool index对应的CORESET，都使用对应的TCI状态去接收CORESET时频资源位置发送的下行控制信令。
如果针对某个CORESET pool index，第三MAC信令没有激活任何一个TCI状态，或MAC信令激活的TCI状态为空，那么终端可以不需要针对该CORESET pool index的CORESET去接收下行控制信令。相当于此种情况下，终端不需要接收来自某个TRP/panel的PDCCH上的下行控制信令。
本公开实施例中，针对不同的TRP/panel实现基于多个时频资源相同的传输资源重复发送或接收同一下行控制信令，也可以配置一个CORESET。但是该CORESET的CORESET pool index取值需要区别于目前传统方法中CORESET pool index。传统方法中的CORESET  pool index取值只有0和1，不同的CORESET pool index取值标识对应不同的TRP/panel。本公开实施例中配置的一个CORESET的一个CORESET pool index用于标识能对应多个不同的TRP/panel。故本公开实施例中，可以为该CORESET配置新的CORESET pool index，该新的CORESET pool index标识该CORESET能被配置多个波束方向。即，新的CORESET pool index标识的CORESET能对应多个TRP/panel。其中，新的CORESET pool index的取值可以是取值0和1以外的值，比如2或3。
针对不同的TRP/panel实现基于多个时频资源相同的传输资源重复发送同一下行控制信令配置一个CORESET，由于一个CORESET对应多个TRP/panel，故配置TCI状态时，RRC信令可以联合配置其TCI状态，其实也是一个RRC信令对应配置一个CORESET的TCI状态列表。同样，MAC信令也是对应激活一个CORESET的TCI状态，但是不是只激活一个，可以激活一个或多个，比如每个TRP/panel激活0个或1个TCI状态。那么终端在接收这个CORESET上的PDCCH时，必须使用MAC信令激活的所有TCI状态对应的接收波束来接收该PDCCH上的下行控制信令。本公开实施例中，将基于多个时频资源相同的传输资源重复发送同一下行控制信令配置一个CORESET方式中配置TCI状态的RRC信令称为第四RRC信令，MAC信令称为第四MAC信令。第四RRC信令用于指示该CORESET的TCI状态列表，第四MAC信令用于激活TCI状态列表中的一个或多个TCI状态。
本公开实施例中，如果第四MAC信令激活了多个TCI状态，那么终端使用该多个TCI状态去接收该CORESET时频资源上发送的PDCCH上的下行控制信令。进一步的，终端会确定第四MAC信令激活的多个TCI状态，肯定是终端可以同时接收的多个TCI状态，即这多个TCI状态对应终端不同的TRP/panel上的接收波束。如果第四MAC信令激活了一个TCI状态，则终端使用这一个TCI状态去接收该CORESET时频资源上发送的PDCCH上的下行控制信令。
本公开上述实施例中，通过配置多个时频资源相同的传输资源的方式实现同一下行控制信令在多个波束方向上传输的方式中，多个波束方向对应相同的小区标识，或对应不同的小区标识，即，多个TRP/panel可以是intra-cell或intel-cell，以适用不同的通信场景需求。其中，如果多个TRP/panel是inter-cell，那么上述配置多个CORESET的方式中，CORESET pool index不一样，还可以是CORESET对应的CORESET pool index和/或小区索引不一样。
进一步的，本公开实施例中，网络设备可以向终端发送第二指示信息，其中，第二指示信息用于指示终端通过多个时频资源相同的传输资源接收所述多个波束方向的同一下 行控制信令。终端接收网络设备发送的第二指示信息，通过多个时频资源相同的传输资源接收多个波束方向的同一下行控制信令。
其中，上述第二指示信息可以是RRC信令和/或MAC信令。该RRC和/或MAC信令可能包含小区索引和/或CORESET pool index和/或CORESET ID。通过第二指示信息指示的方式，可以确定开始启动下行控制信令重复发送的方法。
进一步的，本公开实施例中通过多个相同的时频资源，在多个波束方向上发送同一下行控制信令时，该下行控制信令的时隙位置并不限定。例如，可以是在时隙的起始符号位置，即占用符号0，1，2；也可以在slot的中间位置，比如针对mini-slot的调度。
本公开实施例中通过设计新的CORESET的配置方法，包括RRC信令中的CORESET poll index，以及TCI状态配置相关的RRC信令和激活TCI状态相关的MAC信令的配置，使得终端能够接收来自多个TRP/panel在同样的时频资源上发送的下行控制信令。并且多个TRP/panel可以是来自同一个小区(小区标识相同)，也可以是来自不同小区(小区标识不同)，适用不同的通信场景。通过本公开使得PDCCH的下行控制信令通过不同的波束方向在同样的时频资源上重复发送，从而提高下行控制信令传输的可靠性和鲁棒性。
可以理解的是，本公开实施例上述通过多个TRP/panel使用相同时频资源重复发送或接收同一下行控制信令的实施方式适用于终端和网络设备交互过程。
基于相同的构思，本公开实施例还提供一种数据传输装置。
可以理解的是，本公开实施例提供的数据传输装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例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。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
