Description

信道资源的传输方法、装置、网络设备、终端和*** 技术领域
本发明涉及通信技术领域，具体而言，涉及一种信道资源的传输方法、装置、网络设备、终端和***。
背景技术
网络设备(例如，基站)配置控制资源集合(CORESET)和搜索空间(Search Space)，以使得物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)能够进行传输。控制资源集合在频域上包括多个物理资源块，在时域上包括1～3个正交频分复用(Orthogonal Frequency Division Multiplexing，简称OFDM)符号，且可位于时隙内的任意位置。CORESET占用的时域资源由高层参数半静态配置。搜索空间是一个或多个聚合等级下候选PDCCH(PDCCH candidate)的集合。基站实际发送的PDCCH的聚合等级随时间可变，由于没有相关信令告知用户设备(User Equipment简称UE)，UE需在不同聚合等级下盲检PDCCH，其中，待盲检的PDCCH称为候选PDCCH。UE会在搜索空间内对所有候选PDCCH进行译码，如果循环冗余校验(Cyclic Redundancy Check，简称CRC)通过，则认为所译码的PDCCH的内容对所述UE有效，并利用译码所获得的信息进行后续操作。
在新无线(New Radio，简称NR)中，在每个服务小区的每个下行部分带宽(Bandwidth part，简称BWP)内，网络设备最多可以为用户配置10个搜索空间集合，该搜索空间集合中配置了时域配置信息，用以指示用户检测PDCCH的时域位置。同时网络侧为每个搜索空间集合配置了集合关联的控制资源集合标识CORESET ID，通过CORESET ID用户可以获得该搜索空间集合在频域上的物理资源。每个搜索空间集合有一个唯一关联的CORESET ID。不同的搜索空间集合可以关联到相同的CORESET ID。UE根据搜索空间集合给出的时域和关联的CORESET ID的频域及搜索空间集合中的其它参数来确定PDCCH candidate的时频域位置。
网络设备在配置CORESET时，为每个CORESET配置了一个或一组传输配置指示状态(Transmission configuration indicator state，简称TCI state)，该TCI state用来指示用户在该CORESET关联的Search Space的PDCCH candidate进行解调检测时所对应的信道滤波系数。当网络为某个CORESET配置了一组TCI state，网络设备会通 过MAC控制元素(MAC Control Element，简称MAC CE)信令为该CORESET激活一个唯一的TCI state，用来指示UE在解调PDCCH时的信道滤波系数。
上述相关技术中，若Search Space关联到多个CORESET，每个CORESET都配置了独立的PDCCH candidate数目，则在计算PDCCH的频域资源时，是根据Search Space中的候选信道数目计算得到PDCCH的频域资源,会导致对PDCCH在进行接收检测时UE会对频域资源理解错误,从而导致后续无法正确接收PDCCH的问题，针对上述问题尚未提出有效的解决方案。

图1是根据本发明实施例的一种信道资源的传输方法的流程示意图，如图1所示，在网络设备侧，该方法包括如下步骤：
步骤S102，网络设备向终端设备发送至少一个搜索空间中的候选控制信道；
其中，至少一个搜索空间与至少两个传输配置指示状态存在关联关系，候选控制信道所占用的资源是根据候选控制信道对应的传输配置指示状态，以及与候选控制信道对应的传输配置指示状态对应的控制资源集合确定的。
在步骤S102中，网络设备可以包括应用于3GPP的网络通信设备，特别是应用于NR场景下的网络侧设备，其中，在本申请实施例中网络设备可以为gNB(后续简称： 基站)，基站在配置传输配置指示状态(后续简称：TCI state)的过程中，搜索空间(Search Space，简称SS)与TCI state存在图2a和图2b所示的对应关系，即，SS与TCI state之间的对应关系如图2a和图2b所示，图2a和图2b是根据本发明实施例的信道资源的传输方法中SS与TCI state之间的示意图；
其中，通过对一个Search Space关联到多个具有不同控制资源集合池索引CORESET pool index的控制资源集合CORESET，每个CORESET仅激活一个TCI state(图2a)，或者通过对一个Search Space关联到一个CORESET但是通过为该CORESET配置多个TCI state来支持基于多种发送和接收(Multiple Transmission and Reception，简称Multi-TRP)的PDCCH的重复传输(图2b)。
基站通过步骤S102中得到的至少两个TCI state向终端设备发送候选控制信道，其中，在本申请实施例中终端设备可以包括：智能手机(例如：***为IOS，Android，Windows的手机)，平板电脑，笔记本电脑，智能穿戴设备(例如，智能手表，VR设备，AR设备)等具备射频通信功能的设备；候选控制信道标记为PDCCH candidate。
其中，本申请实施例中网络设备以基站为例，终端设备以智能手机为例，基站通过至少两个TCI state向智能手机发送候选PDCCH，候选PDCCH在传输时，该候选PDCCH所占用的资源根据传输时关联的TCI state和TCI state对应的CORESET确定。以使得智能手机在接收到候选PDCCH后，依据TCI state指示的每个CORESET关联的候选PDCCH数目来确定每个候选PDCCH所对应的控制信道(Control Channel Element，简称CCE)资源，并在对应的CCE资源上接收检测PDCCH。
在本发明实施例中，通过网络设备向终端设备发送至少一个搜索空间中的候选控制信道；其中，至少一个搜索空间与至少两个传输配置指示状态存在关联关系，候选控制信道所占用的资源是根据候选控制信道对应的传输配置指示状态，以及与候选控制信道对应的传输配置指示状态对应的控制资源集合确定的，达到了UE能够在正确的资源上对PDCCH进行检测，并正确接收后续PDCCH的目的，从而实现了通过明确每个TCI state发送的PDCCH的资源，UE在正确的资源上对PDCCH进行检测，进而成功的接收或发送后续数据的技术效果，解决了由于相关技术中对PDCCH的频域资源进行配置是根据搜索空间中的候选信道数目得到的，UE在该频域资源上对PDCCH进行检测会导致后续无法正确接收PDCCH的技术问题。
可选的，本申请实施例提供的信道资源的传输方法中至少一个搜索空间与至少两个传输配置指示状态存在关联关系包括：
方式一：至少一个搜索空间中的至少两个候选控制信道分别关联不同的传输配置 指示状态；
其中，基站为至少一个SS中至少两个候选PDCCH分别关联不同的TCI state，图2c是根据本发明实施例的一种信道资源的传输方法中SS、PDCCH和TCI state之间的配置关系的示意图。如图2c所示，在对一个SS分配候选PDCCH的过程中，每个候选PDCCH各关联对应的TCI state。
方式二：至少一个搜索空间中的至少一个候选控制信道同时关联至少两个传输配置指示状态；
其中，基站为至少一个SS中至少一个候选PDCCH分别关联不同的TCI state，图2d是根据本发明实施例的一种信道资源的传输方法中SS、PDCCH和TCI state之间的配置关系的示意图。如图2d所示，在对一个SS分配候选PDCCH的过程中，每个候选PDCCH关联至少两个TCI state。
方式三：至少一个搜索空间中的至少两个候选控制信道分别关联不同的传输配置指示状态；以及，至少一个搜索空间中的至少一个候选控制信道同时关联至少两个传输配置指示状态。
其中，结合方式一和方式二，在对多个SS分配候选PDCCH的过程中，可以分别对各个SS依据方式一和方式二，配置每个候选PDCCH对应的TCI state。
进一步地，可选的，至少两个传输配置指示状态是网络设备分别为不同的控制资源集合激活的；和/或，至少两个传输配置指示状态是网络设备为一个控制资源集合同时激活的。
需要说明的是，结合图2a至图2d，SS，CORESET，TCI state和候选PDCCH之间的关系可以为：每个TCI state是分别对应各自的CORESET激活的，和/或，每个TCI state是基于同一个CORESET激活的；
例如：TCI state 1是基站为CORESET 1激活的，TCI state 2是基站为CORESET 2激活的，……，TCI state N是基站为CORESET N激活的；和/或，TCI state 1，TCI state 2，……TCI state N是基站为CORESET同时激活的。
在“和”的情况下，即，至少两个传输配置指示状态是网络设备分别为不同的控制资源集合激活的；和，至少两个传输配置指示状态是网络设备为一个控制资源集合同时激活的，可以对应于上述方式三的实现场景，分别针对不同的SS依据至少两个传输配置指示状态是网络设备分别为不同的控制资源集合激活的；和，至少两个传输配置指示状态是网络设备为一个控制资源集合同时激活的配置TCI state。
进一步地，可选的，不同的控制资源集合具有不同的控制资源集合池索引。
在一种可实现的方式中，结合上述方式一至三中的场景在存在多个CORESET的情况下，每个CORESET具有各自对应的CORESET pool index。
可选的，网络设备通过为搜索空间配置关联的控制资源集合，配置与控制资源集合关联的传输配置指示状态。
如图2a至图2d所示，通过为SS配置对应的CORESET，并通过CORESET来关联对应的TCI state；例如：结合上述方式一至三，以一个SS为例，在对一个SS进行配置时，一个SS可以配置一个CORESET或多个CORESET，在配置一个CORESET的情况下，配置与该CORESET关联的多个TCI state；在配置多个CORESET的情况下，配置与每个CORESET关联的TCI state，即，每个CORESET分别对应一个TCI state。
基于上述配置，网络设备向终端设备发送至少一个搜索空间中的候选控制信道的过程，即，基站在通过至少两个TCI state向智能手机发送候选PDCCH的过程可以包括如下方式：
方式一：网络设备通过候选控制信道发送下行控制信息的时候，通过其中一个候选控制信道及候选控制信道所关联的至少两个传输配置指示状态发送下行控制信息；
其中，在一个候选PDCCH关联了至少两个TCI state的情况下，当基站发送下行控制信息，例如，DCI(下行控制信令，Downlink control information)时，可以通过多个候选PDCCH中的一个候选PDCCH，和该候选PDCCH所关联的至少两个TCI state发送。
方式二：网络设备通过候选控制信道发送下行控制信息的时候，通过至少两个候选控制信道及至少两个候选控制信道所分别关联的传输配置指示状态发送下行控制信息；
其中，在每个候选PDCCH关联了对应的TCI state的情况下，当基站发送下行控制信息，例如，DCI(下行控制信令，Downlink control information)时，可以通过至少两个候选PDCCH，和该至少两个候选PDCCH所关联的TCI state发送该下行控制信息。
方式三：网络设备通过候选控制信道发送下行控制信息的时候，通过其中一个候选控制信道及候选控制信道所关联的至少两个传输配置指示状态发送下行控制信息；以及，通过至少两个候选控制信道及至少两个候选控制信道所分别关联的传输配置指示状态发送下行控制信息。
其中，结合方式一和方式二，在存在多个候选PDCCH的情况下，且有的候选PDCCH关联了至少两个TCI State，有的候选PDCCH与TCI state一一对应，基站通过在多个候选PDCCH中选择不同类型的候选PDCCH，通过与该候选PDCCH类型关联的TCI state进行下行控制信息的传输，具体实现可以为同时通过上述方式一和方式二发送下行控制信息。
进一步地，可选的，确定候选控制信道所占用的资源的步骤包括：网络设备确定候选控制信道的聚合等级；网络设备确定聚合等级中关联到同一传输配置指示状态的候选控制信道数目；网络设备确定传输配置指示状态对应的控制资源集合的物理资源；网络设备基于候选控制信道数目及控制资源集合的物理资源确定候选控制信道传输时所占用的资源。
在一种可实现的方式中，网络设备以配置一个SS为例，网络设备以基站为例进行说明：
基站配置一个Search Space，该Search Space关联到2个CORESET；
基站为每个CORESET在任一时刻仅激活了一个TCI state。
基站为Search Space的聚合等级8配置了候选数目8个PDCCH，其中前4个PDCCH candidate仅由CORESET 0所指示的TCI state发送，后4个PDCCH candidate仅由CORESET1指示的TCI state发送。其中，在本申请实施例中聚合等级8可以为任意聚合等级，也可以仅配置部分聚合等级，以实现本申请实施例提供的信道资源的传输方法为准，具体不做限定。
其中，网络设备基于候选控制信道数目及控制资源集合的物理资源确定候选控制信道传输时的所占用的资源包括：
仅对CORESET0举例，基站基于该Search Space中仅关联到CORESET 0所指示的TCI state对应的候选PDCCH数目及CORESET 0的CCE数目(即，本申请实施例中的控制资源集合的物理资源)计算上述候选PDCCH数目的PDCCH所占用的CCE(控制信道元素,Control Channel Element)资源(即，本申请实施例中的候选控制信道传输时的所占用的资源)。即

计算CCE资源时，m s,nci仅为搜索空间中对CORESET 0所指示的TCI state的候选PDCCH(在该实施例中，候选PDCCH 0-3对应到CORESET 0，候选PDCCH 4-7对 应到CORESET1，其中在计算CORESET 0中的候选PDCCH的CCE资源时，m s,nci的0-3依次对应于候选PDCCH 0-3，在计算CORESET 1中的候选PDCCH的CCE资源时，m s,nci的0-3依次对应于PDCCH candidate 4-7)。N CCE,p为该候选PDCCH所对应的CORESET的CCE数目。

为搜索空间s中所有配置的服务小区n CI仅关联到CORESET0为终端配置的聚合等级为L的PDCCH candidate数目的最大值。
终端设备(例如，智能手机)基于网络设备(例如，基站)的每个CORESET关联的候选PDCCH数目来确定每个候选PDCCH所对应的CCE资源，并在对应的CCE资源上接收检测PDCCH。
综上，本申请实施例提供的信道资源的传输方法在发送下行控制信息时包括如下方式：
方式一，网络设备通过其中一个候选控制信道及候选控制信道所关联的至少两个传输配置指示状态发送下行控制信息，包括：网络设备通过一个候选控制信道所关联的各传输配置指示状态分别发送下行控制信息一次；或者，网络设备将下行控制信息的各部分内容通过的一个候选控制信道所关联的各传输配置指示状态分别发送。
其中，下行控制信息可以通过一个候选PDCCH所关联的多个TCI state分别传输一次，即，通过一个候选PDCCH所关联的各TCI state重复发送一条下行控制信息；
或，
将该下行控制信息中的各部分内容通过该候选PDCCH所关联的各TCI state分别进行传输，即，将一条下行控制信息进行拆分，并由确定的候选PDCCH所关联的各个TCI state对拆分的下行控制信息中的各部分进行发送；例如，各TCI state分别对应下行控制信息中的一部分。如图2e所示，图2e是根据本发明实施例的一种信道资源的传输方法中各TCI state与拆分的下行控制信息之间位置对应的示意图。
方式二，网络设备通过至少两个候选控制信道及至少两个候选控制信道所分别关联的传输配置指示状态发送下行控制信息，包括：网络设备通过至少两个候选控制信道发送相同的下行控制信息；或者，网络设备通过至少两个候选控制信道传输相同的下行控制信息的不同部分的内容；其中，至少两个候选控制信道分别关联的传输配置指示状态不同。
区别于方式一，在方式二中，网络设备通过SS中至少两个候选PDCCH进行下行控制信息的传输，在传输过程中，可以令该至少两个候选PDCCH发送同一下行控制信息；也可以令两个候选PDCCH传输同一下行控制信息的不同部分的内容。
例如：有候选PDCCH 1和候选PDCCH 2，在传输下行控制信息时，可以通过候选PDCCH 1和候选PDCCH 2对同一下行控制信息分别进行发送，即，使用两个信道发送重复的信息；或，
下行控制信息包括part1和part2，在发送时，通过候选PDCCH1发送part1部分，通过候选PDCCH2发送part2部分。
需要说明的是，两个候选控制信道关联的传输配置指示状态不同，即，候选PDCCH0对应TCI state 0，候选PDCCH 1对应TCI state 1。
方式三，网络设备通过其中一个候选控制信道及候选控制信道所关联的至少两个传输配置指示状态发送下行控制信息；以及，通过至少两个候选控制信道及至少两个候选控制信道所分别关联的传输配置指示状态发送下行控制信息，包括：网络设备通过一个候选控制信道所关联的各传输配置指示状态分别发送下行控制信息；或者，网络设备将下行控制信息的各部分内容通过的一个候选控制信道所关联的各传输配置指示状态分别发送；以及，网络设备通过至少两个候选控制信道发送相同的下行控制信息；或者，网络设备通过至少两个候选控制信道传输相同的下行控制信息的不同部分的内容；其中，至少两个候选控制信道分别关联的传输配置指示状态不同。
其中，方式三为结合方式一和二在发送下行控制信息时的实现方式。
可选的，本申请实施例提供的信道资源的传输方法还包括：网络设备指示搜索空间中的候选控制信道之间的关联关系；网络设备在确定通过搜索空间中的一个候选控制信道进行下行控制信息传输时，网络设备根据候选控制信道之间的关联关系确定下行控制信息通过搜索空间中对应的候选控制信道进行重复传输；或者，确定下行控制信息的各部分内容通过搜索空间中对应的候选控制信道分别进行传输。
其中，基于上述方式二，网络设备通过SS中的候选PDCCH之间的关联关系传输下行控制信息；
例如：通过预配置或高层信令指示聚合等级为8的通过TCI state 0发送的8个候选PDCCH和通过TCI state 1发送的5个候选PDCCH存在某种对应。即，网络设备选择通过前3个候选PDCCH中的第i个候选PDCCH发送下行控制信息时，网络设备会在后5个候选PDCCH中的相同的第k个候选PDCCH发送相同的下行控制信息。或，
通过i个候选PDCCH发送下行控制信息的part1，通过第k个候选PDCCH发送下行控制信息的part2。
综上，本申请实施例提供的信道资源的传输方法在实际应用中包括如下示例：
示例1：
网络设备配置一个Search Space，该Search Space关联到2个CORESET。
网络设备为每个CORESET在任一时刻仅激活了一个TCI state。
网络设备为Search Space的聚合等级8配置了候选PDCCH数目8个，其中前4个候选PDCCH仅由CORESET 0所指示的TCI state发送，后4个候选PDCCH仅由CORESET 1指示的TCI state发送。其中，聚合等级可以为任意聚合等级，也可以仅配置部分聚合等级。
网络设备通过该Search Space及关联的CORESET 0指示的TCI state所对应的候选PDCCH中的一个候选PDCCH来发送给终端设备并指示相关下行控制信息，其中，指示的下行控制信息可以用于调度一个信道；
网络设备通过该Search Space及关联的CORESET 1指示的TCI state所对应的候选PDCCH中的一个候选PDCCH来发送给终端设备并指示相关下行控制信息，其中，指示的下行控制信息可以用于调度一个信道。
网络设备通过CORESET 0的TCI state 0和CORESET1的TCI state 1分别发送的PDCCH可以是用来调度的同一个信道，也可以是调度不同的信道。
当调度同一个信道时，网络设备会通过预配置或高层信令指示聚合等级为8的前4个候选PDCCH和后4个候选PDCCH存在某种对应。即，网络设备选择通过前4个候选PDCCH中的第i个候选PDCCH发送下行控制信息时，网络设备会在后4个候选PDCCH中的相同的第k个候选PDCCH发送相同的下行控制信息。该两个下行控制信息调度同一个信道。
基于CORESET 0关联的TCI state为例，网络设备基于该Search Space中仅关联到CORESET 0所指示的TCI state对应的候选PDCCH数目，以及CORESET 0的CCE数目计算该候选PDCCH数目的信道所占用的CCE(控制信道元素，Control Channel Element)资源。计算过程如下：

需要说明的是，该示例与示例1的不同在于：CORESET 0关联的候选PDCCH数目和CORESET 1关联的候选PDCCH数目不同；
即，示例1中是根据聚合等级8将候选PDCCH的数目中，前4个候选PDCCH分配给CORESET 0所指示的TCI state发送；后4个候选PDCCH分配给CORESET 1所指示的TCI state发送；
在本示例中根据聚合等级8，按照前3个候选PDCCH分配给CORESET 0所指示的TCI state发送；后5个候选PDCCH分配给CORESET 1所指示的TCI state发送进行设置。
网络设备通过该Search Space及关联的CORESET 0指示的TCI state所对应的候选PDCCH中的一个候选PDCCH来发送给终端设备并指示相关下行控制信息，其中，指示的下行控制信息可以用于调度一个信道；
网络设备通过该Search Space及关联的CORESET 1指示的TCI state所对应的候选PDCCH中的一个候选PDCCH来发送给终端设备并指示相关下行控制信息，其中，指示的下行控制信息可以用于调度一个信道。
网络设备通过CORESET 0的TCI state 0和CORESET1的TCI state 1分别发送的PDCCH可以是用来调度的同一个信道，也可以是调度不同的信道。
当调度同一个信道时，网络设备会通过预配置或高层信令指示聚合等级为8的前3个候选PDCCH和后5个候选PDCCH存在某种对应。即，网络设备选择通过前3个候选PDCCH中的第i个候选PDCCH发送下行控制信息时，网络设备会在后5个候选PDCCH中的相同的第k个候选PDCCH发送相同的下行控制信息。这两个下行控制信息调度同一个信道。
基于CORESET 0关联的TCI state为例，网络设备基于该Search Space中仅关联到CORESET 0所指示的TCI state对应的候选PDCCH数目，以及CORESET 0的CCE数目计算该候选PDCCH数目的信道所占用的CCE(控制信道元素，Control Channel Element)资源。计算过程如下：

示例3：
网络设备配置一个Search Space，该Search Space关联到2个CORESET。
网络设备为每个CORESET在任一时刻仅激活了一个TCI state。
网络设备为Search Space的聚合等级8配置了8个候选PDCCH，其中在时刻T0选择8个候选PDCCH中的一个候选PDCCH由CORESET 0所指示的TCI state 0传输下行控制信息。在时刻T1选择8个候选PDCCH中的一个候选PDCCH由CORESET 1所指示的TCI state 1传输下行控制信息。
需要说明的是，本示例区别于示例1在于：8个候选PDCCH都会通过CORESET0和CORESET 1来发。时刻T0和时刻T1可以相同，也可以不相同。若相同，则都在时刻T0的时候分别通过CORESET 0和CORESET 1指示的TCI state传两次PDCCH。
另外，确定的候选PDCCH在8个候选PDCCH中的CORESET pool index可以是相同的，也可以是不同的。比如CORESET 0选的CORESET pool index为0的候选PDCCH，CORESET 1选的CORESET pool index为1的候选PDCCH。
网络设备通过该Search Space及关联的CORESET 0指示的TCI state所对应的候选PDCCH中的一个候选PDCCH来发送给终端设备并指示相关下行控制信息，其中，指示的下行控制信息可以用于调度一个信道；
网络设备通过该Search Space及关联的CORESET 1指示的TCI state所对应的候选PDCCH中的一个候选PDCCH来发送给终端设备并指示相关下行控制信息，其中，指示的下行控制信息可以用于调度一个信道。
网络设备通过CORESET 0的TCI state 0和网络设备通过CORESET1的TCI state 1分别发送的PDCCH可以是用来调度同一个信道的，也可以是调度不同的信道的。
当调度同一个信道时，网络设备会通过预配置或高层信令指示聚合等级为8的前3个候选PDCCH和后5个候选PDCCH存在某种对应。即，网络设备选择通过前3个候选PDCCH中的第i个候选PDCCH发送下行控制信息时，网络设备会在后5个候选PDCCH中的相同的第k个候选PDCCH发送相同的下行控制信息。这两个下行控制信息调度同一个信道。
在时刻T0网络设备基于该Search Space中仅关联到CORESET 0所指示的TCI state 0对应的候选PDCCH数目，以及CORESET 0的CCE数目计算该候选PDCCH数目的信道所占用的CCE资源。
在时刻T1网络设备基于该Search Space中关联到CORESET 1所指示的TCI state 1对应的候选PDCCH数目，以及CORESET 1的CCE数目计算该候选PDCCH数目的信道所占用的CCE资源。
网络设备在T0时刻从基于CORESET 0和TCI state 0计算得到的该候选PDCCH数目的信道对应的CCE资源中选择一个PDCCH所占用的CCE资源来传输下行控制信息。
网络设备在T1时刻从基于CORESET 1和TCI state 1计算得到的该候选PDCCH数目的信道对应的CCE资源中选择一个PDCCH所占用的CCE资源来传输下行控制信息。
网络设备在T0和T1时刻所选择的PDCCH传输的下行控制信息为一个控制信道的重复传输。
终端设备基于网络设备指示的每个CORESET关联的候选PDCCH数目来确定每个候选PDCCH所对应的CCE资源，并在对应的CCE资源上接收检测PDCCH。
本申请实施例提供的信道资源的传输方法通过明确每个TCI state发送的PDCCH的资源，UE才能在正确的资源上对PDCCH进行检测，从而进行后续数据的接收或发送。
需要说明的是，本申请实施例提供的信道资源的传输方法中上述示例记载的SS，CORESET，TCI state和候选PDCCH之间的关联关系，也可以表述成对应关系，以实现本申请实施例提供的信道资源的传输方法为准，具体不做限定。
实施例2
根据本发明实施例的另一方面，还提供了一种信道资源的传输方法，图3是根据本发明实施例的一种信道资源的传输方法的流程示意图，如图3所示，在终端设备侧，包括：
步骤S302，终端设备获取网络设备发送的至少一个搜索空间中候选控制信道关联的至少两个传输配置指示状态；其中，传输配置指示状态，用于指示终端设备接收候选控制信道时的信道参数；
在步骤S302中，终端设备可以包括应用于3GPP的终端设备，特别是应用于NR场景下的终端设备，其中，在本申请实施例中终端设备可以包括：智能手机(例如：***为IOS，Android，Windows的手机)，平板电脑，笔记本电脑，智能穿戴设备(例如，智能手表，VR设备，AR设备)等具备射频通信功能的设备；
终端设备以智能手机为例，智能手机获取基站(对应实施例1中的网络设备)配置的候选控制信道的至少一个搜索空间同时关联至少两个传输配置指示状态(后续简称：TCI state)；
其中，搜索空间(Search Space，简称SS)与TCI state的对应关系见实施例1中的图2a和图2b。
即，通过对一个Search Space关联到多个具有不同控制资源集合池索引CORESET pool index的控制资源集合CORESET，其中每个CORESET仅激活一个TCI state，或者通过对一个Search Space关联到一个CORESET但是通过为该CORESET配置多个TCI state来支持基于多种发送和接收(Multiple Transmission and Reception，简称Multi-TRP)的PDCCH的重复传输。
步骤S304，终端设备根据候选控制信道关联的传输配置指示状态及传输配置指示 状态对应的控制资源集合，确定候选控制信道所占用的资源。
在步骤S304中，基于步骤S302中终端设备获取的网络设备配置的TCI state，仍以终端设备为智能手机为例，智能手机在接收到候选PDCCH后，依据指示的每个CORESET关联的候选PDCCH数目来确定每个候选PDCCH所对应的控制信道(Control Channel Element，简称CCE)资源，并在对应的CCE资源上接收检测PDCCH。
在本发明实施例中，通过终端设备获取网络设备发送的至少一个搜索空间中候选控制信道关联的至少两个传输配置指示状态；其中，传输配置指示状态，用于指示终端设备接收候选控制信道时的信道参数；终端设备根据候选控制信道关联的传输配置指示状态及传输配置指示状态对应的控制资源集合，确定候选控制信道所占用的资源，达到了UE能够在正确的资源上对PDCCH进行检测，并正确接收后续PDCCH的目的，从而实现了通过明确每个TCI state发送的PDCCH的资源，UE在正确的资源上对PDCCH进行检测，进而成功的接收或发送后续数据的技术效果，解决了由于相关技术中对PDCCH的频域资源进行配置是根据搜索空间中的候选信道数目得到的，UE在该频域资源上对PDCCH进行检测会导致后续无法正确接收PDCCH的技术问题。
可选的，传输配置指示状态是网络设备为搜索空间关联的控制资源集合配置的。
其中，TCI state是UE通过网络设备为SS关联的CORESET来获取的。
通过为SS配置对应的CORESET，并通过CORESET来关联对应的TCI state；例如：以一个SS为例，在对一个SS进行配置时，一个SS可以配置一个CORESET或多个CORESET，在配置一个CORESET的情况下，配置与该CORESET关联的多个TCI state；在配置多个CORESET的情况下，配置与每个CORESET关联的TCI state，即，每个CORESET分别对应一个TCI state。
可选的，步骤S302中终端设备获取网络设备发送的至少一个搜索空间中候选控制信道关联的至少两个传输配置指示状态包括：
方式一，终端设备获取网络设备为至少一个搜索空间中至少两个候选控制信道分别关联的不同的传输配置指示状态；
其中，对应实施例1中的方式一，网络设备以基站为例，基站为至少一个SS中至少两个候选PDCCH分别关联不同的TCI state，在对一个SS分配候选PDCCH的过程中，每个候选PDCCH各关联对应的TCI state。
方式二，终端设备获取网络设备为至少一个搜索空间中至少一个候选控制信道同时关联的至少两个传输配置指示状态；
其中，对应实施例1中的方式二，网络设备以基站为例，基站为至少一个SS中至少一个候选PDCCH分别关联不同的TCI state，在对一个SS分配候选PDCCH的过程中，每个候选PDCCH关联至少两个TCI state。
方式三，终端设备获取网络设备为至少一个搜索空间中的至少两个候选控制信道分别关联不同的传输配置指示状态；以及，终端设备获取网络设备为至少一个搜索空间中的至少一个候选控制信道同时关联至少两个传输配置指示状态。
其中，对应实施例1中的方式三，结合方式一和方式二，在对多个SS分配候选PDCCH的过程中，可以分别对各个SS依据方式一和方式二，配置每个候选PDCCH对应的TCI state。
可选的，至少两个传输配置指示状态是网络设备分别为不同的控制资源集合激活的；和/或，至少两个传输配置指示状态是网络设备为一个控制资源集合同时激活的。
其中，SS，CORESET，TCI state和候选PDCCH之间的关系可以为：每个TCI state是分别对应各自的CORESET激活的，和/或，每个TCI state是基于同一个CORESET激活的；
例如：TCI state 1是基站为CORESET 1激活的，TCI state 2是基站为CORESET 2激活的，……，TCI state N是基站为CORESET N激活的；和/或，TCI state 1，TCI state 2，……TCI state N是基站为CORESET同时激活的。
在“和”的情况下，即，至少两个传输配置指示状态是网络设备分别为不同的控制资源集合激活的；和，至少两个传输配置指示状态是网络设备为一个控制资源集合同时激活的，可以对应于上述实现场景，分别针对不同的SS依据至少两个传输配置指示状态是网络设备分别为不同的控制资源集合激活的；和/或，至少两个传输配置指示状态是网络设备为一个控制资源集合同时激活的配置TCI state。
进一步地，可选的，不同的控制资源集合具有不同的控制资源集合池索引。
在一种可实现的方式中，在存在多个CORESET的情况下，每个CORESET具有各自对应的CORESET pool index。
基于上述配置，终端设备在接收网络设备发送的下行控制信息可以通过如下方式得到：
方式一，终端设备接收网络设备通过候选控制信道发送的下行控制信息，下行控制信息为通过其中一个候选控制信道及候选控制信道所关联的至少两个传输配置指示状态发送的；
其中，终端设备接收的下行控制信息可以为：在一个候选PDCCH关联了至少两个TCI state的情况下，当基站发送下行控制信息，例如，DCI(下行控制信令，Downlink control information)时，可以通过多个候选PDCCH中的一个候选PDCCH，和该候选PDCCH所关联的至少两个TCI state发送得到的。
方式二，终端设备接收网络设备通过候选控制信道发送的下行控制信息，下行控制信息为通过至少两个候选控制信道及至少两个候选控制信道所分别关联的传输配置指示状态发送的；
其中，终端设备接收的下行控制信息可以为：在每个候选PDCCH关联了对应的TCI state的情况下，当基站发送下行控制信息，例如，DCI(下行控制信令，Downlink control information)时，可以通过至少两个候选PDCCH，和该至少两个候选PDCCH所关联的TCI state发送该下行控制信息。
方式三，终端设备接收网络设备通过候选控制信道发送的下行控制信息，下行控制信息为通过其中一个候选控制信道及候选控制信道所关联的至少两个传输配置指示状态发送的；以及，通过至少两个候选控制信道及至少两个候选控制信道所分别关联的传输配置指示状态发送的。
其中，终端设备接收的下行控制信息可以为：结合方式一和方式二，在存在多个候选PDCCH的情况下，且有的候选PDCCH关联了至少两个TCI State，有的候选PDCCH关联对应的TCI state，基站通过在多个候选PDCCH中选择不同类型的候选PDCCH，通过与该候选PDCCH类型关联的TCI state进行下行控制信息的传输，具体实现可以为同时通过上述方式一和方式二发送下行控制信息。
可选的，步骤S304中终端设备根据候选控制信道关联的传输配置指示状态及传输配置指示状态对应的控制资源集合，确定候选控制信道所占用的资源包括：终端设备获取网络设备确定的候选控制信道的聚合等级；终端设备获取聚合等级中关联到同一传输配置指示状态的候选控制信道数目；终端设备获取传输配置指示状态对应的控制资源集合的物理资源；终端设备基于候选控制信道数目及物理资源确定候选控制信道传输时所占用的资源；其中，终端设备在其中一个物理资源上根据对应的传输配置指示状态进行下行控制信息检测。
在一种可实现的方式中，以配置一个SS为例，网络设备以基站为例进行说明：
基站配置一个Search Space，该Search Space关联到2个CORESET；
基站为每个CORESET在任一时刻仅激活了一个TCI state。
基站为Search Space的聚合等级8配置了候选数目8个PDCCH，其中前4个PDCCH candidate仅由CORESET 0所指示的TCI state发送，后4个PDCCH candidate仅由CORESET1指示的TCI state发送。其中，在本申请实施例中聚合等级8可以为任意聚合等级，也可以仅配置部分聚合等级，以实现本申请实施例提供的信道资源的传输方法为准，具体不做限定。
其中，基站基于候选控制信道数目及控制资源集合的物理资源确定候选控制信道传输时的所占用的资源包括：
仅对CORESET0举例，基站基于该Search Space中仅关联到CORESET 0所指示的TCI state对应的候选PDCCH数目及CORESET 0的CCE数目(即，本申请实施例中的控制资源集合的物理资源)计算上述候选PDCCH数目的PDCCH所占用的CCE(控制信道元素,Control Channel Element)资源(即，本申请实施例中的候选控制信道传输时的所占用的资源)。即

计算CCE资源时，m s,nci仅为搜索空间中对CORESET 0所指示的TCI state的候选PDCCH(在该实施例中，候选PDCCH 0-3对应到CORESET 0，候选PDCCH 4-7对应到CORESET1，其中在计算CORESET 0中的候选PDCCH的CCE资源时，m s,nci的0-3依次对应于候选PDCCH 0-3，在计算CORESET 1中的候选PDCCH的CCE资源时，m s,nci的0-3依次对应于PDCCH candidate 4-7)。N CCE,p为该候选PDCCH所对应的CORESET的CCE数目。

终端设备(例如，智能手机)基于网络设备(例如，基站)的每个CORESET关联的候选PDCCH数目来确定每个候选PDCCH所对应的CCE资源，并在对应的CCE资源上接收检测PDCCH。
综上，本申请实施例提供的信道资源的传输方法在接收下行控制信息时包括如下方式：
方式一，下行控制信息为网络设备通过搜索空间中关联至少两个传输配置指示状态的一个候选控制信道发送的，其中，下行控制信息为网络设备通过一个候选控制信道所关联的各传输配置指示状态分别发送一次的信息，或者，下行控制信息中的各部分内容为网络设备通过的一个候选控制信道所关联的各传输配置指示状态分别发送的。
其中，对应实施例1中“发送下行控制信息”的方式一，终端设备接收的下行控制信息为网络设备通过搜索空间中的关联了至少两个传输配置指示状态的一个候选控制信道发送的，该过程中：
下行控制信息可以通过一个候选PDCCH所关联的多个TCI state分别传输一次，即，通过一个候选PDCCH所关联的TCI state重复发送一条下行控制信息；
或，
将该下行控制信息中的各部分内容通过该候选PDCCH所关联的各TCI state分别进行传输，即，将一条下行控制信息进行拆分，并由确定的候选PDCCH所关联的各个TCI state对拆分的下行控制信息中的各部分进行发送；例如，各TCI state分别对应下行控制信息中的一部分。
方式二，下行控制信息为网络设备通过搜索空间中至少两个候选控制信道发送的，其中，下行控制信息为至少两个候选控制信道重复传输得到的，或者，下行控制信息的不同部分的内容为至少两个候选控制信道分别传输得到的；其中，至少两个候选控制信道分别关联的传输配置指示状态不同。
区别于方式一，在方式二中，对应实施例1中“发送下行控制信息”的方式二，终端设备接收的下行控制信息为网络设备通过SS中至少两个候选PDCCH发送的，在传输过程中，可以令该至少两个候选PDCCH发送同一下行控制信息；也可以令两个候选PDCCH传输同一下行控制信息的不同部分的内容。
例如：有候选PDCCH 1和候选PDCCH 2，在传输下行控制信息时，可以通过候选PDCCH 1和候选PDCCH 2对同一下行控制信息分别进行发送，即，使用两个信道发送重复的信息；或，
下行控制信息包括part1和part2，在发送时，通过候选PDCCH1发送part1部分，通过候选PDCCH2发送part2部分。
需要说明的是，两个候选控制信道关联的传输配置指示状态不同，即，候选PDCCH0对应TCI state 0，候选PDCCH 1对应TCI state 1。
方式三，下行控制信息为网络设备通过搜索空间中关联至少两个传输配置指示状态的一个候选控制信道发送的，其中，下行控制信息为网络设备通过一个候选控制信道所关联的各传输配置指示状态分别发送一次的信息，或者，下行控制信息中的各部分内容为网络设备通过的一个候选控制信道所关联的各传输配置指示状态分别发送的；以及，下行控制信息为网络设备通过搜索空间中至少两个候选控制信道发送的，其中， 下行控制信息为至少两个候选控制信道重复传输得到的，或者，下行控制信息的不同部分的内容为至少两个候选控制信道分别传输得到的；其中，至少两个候选控制信道分别关联的传输配置指示状态不同。
其中，方式三为结合方式一和二在接收下行控制信息时的实现方式。
可选的，本申请实施例提供的信道资源的传输方法还包括：终端设备依据网络设备指示搜索空间中的候选控制信道之间的关联关系，通过搜索空间中的一个候选控制信道接收下行控制信息；其中，下行控制信息为网络设备根据候选控制信道之间的关联关系确定下行控制信息通过搜索空间中对应的候选控制信道进行重复传输；或者，确定下行控制信息的各部分内容通过搜索空间中对应的候选控制信道分别进行传输。
需要说明的是，网络设备通过候选PDCCH关联的至少两个TCI state发送的控制信息，在终端设备接收时，可以选择通过对信息进行检测，若是重复发送的，仅需接收一次即可，节省了信道资源，提升了报文响应效率。
