技术领域
本公开实施例涉及通信技术领域，尤其涉及一种信道传输方法、设备及系统。
背景技术
目前，网络设备与终端设备(User Equipment，UE)之间可以采用多个发送接收点(Transmission Reception Point，TRP)传输数据，从而可以提高传输数据的可靠性及吞吐量。
在网络设备与UE之间采用多个TRP传输数据的过程中，当UE发生移动、转动或者被其他物体遮挡时，UE可能需要重选TRP，即可能会使得网络设备与UE之间传输数据的TRP发生变更(包括替换TRP、增加TRP、删减TRP等)。当网络设备确定需要为一个UE变更TRP时，网络设备可以通过无线资源控制(Radio Resource Control，RRC)信令为UE重配置与变更后的TRP对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)配置信息PDCCH-Config、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)配置信息PDSCH-Config、物理上行控制信道(Physical Uplink Control Channel，PUCCH)配置信息PUCCH-Config以及物理上行共享信道(Physical Uplink Shared Channel，PUSCH)配置信息PUSCH-Config。
然而，由于RRC信令的传输过程比较复杂，因此上述通过RRC信令重配置PDCCH配置信息的方法所需的时间较长，并且，在UE快速移动或转动的场景下，可能会出现重配置失败的现象，从而导致通信质量下降或通信中断。
发明内容
本公开实施例提供一种信道传输方法、设备及系统，以解决相关技术中在UE快速移动或转动的场景下由于会出现重配置失败的现象而导致通信质量下降或通信中断的问题。

第三方面，本公开实施例提供了一种UE，该UE包括确定模块和收发模块。确定模块用于根据目标信息，从信道配置信息集合中确定与该目标信息对应的目标传输参数。收发模块用于根据确定模块确定的该目标传输参数，发送或接收目标信道。
第四方面，本公开实施例提供了一种网络设备，该网络设备包括收发模块，该收发模块用于向UE指示目标信息，该目标信息用于从信道配置信息集合中确定与该目标信息对应的目标传输参数；并根据目标传输参数，接收或发送目标信道。
第五方面，本公开实施例提供了一种UE，包括处理器、存储器及存储在该存储器上并可在该处理器上运行的计算机程序，该计算机程序被该处理器执行时实现上述第一方面提供的信道传输方法的步骤。
第六方面，本公开实施例提供了一种网络设备，包括处理器、存储器及存储在该存储器上并可在该处理器上运行的计算机程序，该计算机程序被该处理器执行时实现上述第二方面提供的信道传输方法的步骤。
第七方面，本公开实施例提供了一种通信系统，该通信系统包括上述第三方面中的UE，以及上述第四方面中的网络设备。或者，该通信系统包括上述第五方面中的UE，以及上述第六方面中的网络设备。
第八方面，本公开实施例提供了一种计算机可读存储介质，该计算机可读存储介质上存储计算机程序，该计算机程序被处理器执行时实现上述第一方面或者第二方面中的信道传输方法的步骤。
在本公开实施例中，可以根据目标信息，从信道配置信息集合中确定与该目标信息对应的目标传输参数；并根据该目标传输参数，发送或接收目标信道；其中，目标信息是网络设备用于指示变更为UE提供服务的TRP；信道配置信息集合是网络设备在向UE指示目标信息之前，为UE预先配置的。通过该方案，与相关技术中TRP发生变更后，通过RRC信令重配置(重配置时间较长)相比，本公开实施例通过MAC CE向UE指示目标信息，从网络设备预先配置给UE的信道配置信息集合中确定目标传输参数，进而可以根据目标传输参数，传输目标信道，如此可以实现在TRP发生变更后快速重配置信道配置信息，保证通信质量连续性。

UE是一种向用户提供语音和/或数据连通性的设备，具有有线/无线连接功能的手持式设备，或连接到无线调制解调器的其他处理设备。UE可以经过无线接入网(Radio Access Network，RAN)与一个或多个核心网设备进行通信。UE可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与RAN交换语言和/或数据，例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。UE也可以称为用户代理(User Agent)或者终端设备等。
网络设备是一种部署在RAN中用于为UE提供无线通信功能的设备。本公开实施例中，网络设备可以为基站，且基站可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。例如，在5G系统中，可以称为5G基站(gNB)、TRP；在第四代无线通信(4-Generation，4G)系统，如长期演进(long term evolution，LTE)系统中，可以称为演进型基站(evolved NodeB，eNB)；在第三代移动通信(3G)系统中，可以称为基站(Node B)。随着通信技术的演进，“基站”这一名称可能会发生变化。
下面结合附图，通过具体的实施例及其应用场景对本公开实施例提供的信道传输方法、设备及系统进行详细地说明。
基于如图1所示的通信系统，本公开实施例提供一种信道传输方法，如图2所示，该信道传输方法可以包括下述的步骤201-步骤205。
步骤201、网络设备向UE指示目标信息。
其中，该目标信息是网络设备用于指示变更为UE提供服务的TRP。
可选地，本公开实施例中，上述目标信息可以为目标信道配置信息标识、或者可以为至少一个目标TRP标识、或者可以为目标BWP标识、或者可以为至少一个目标TRP标识、或者可以为至少一个目标参数标识、或者可以为至少一个目标传输配置标识(Transmission Configuration Indicator，TCI)，或者可以为其它任意满足实际使用需求的信息，具体可以根据实际使用需求确定，本公开实施例不作限定。下文中将结合应用场景，针对目标信息进行详细描述，此处不予赘述。
可选地，本公开实施例中，网络设备可以通过物理层信息或媒体接入控制(Media Access Control，MAC)层信息，向UE指示上述目标信息。
具体的，本公开实施例中，网络设备可以通过物理层控制信令——下行控制信息(Downlink Control Information，DCI)或MAC层的控制单元(Control Element，CE)，向UE指示上述目标信息。
步骤202、UE接收目标信息。
本公开实施例中，UE可以接收网络设备通过MAC CE指示的目标信息，例如，该目标信息可以携带将要在生效时间后使用的目标信道配置信息标识、或者至少一个目标TRP标识、或者目标BWP标识、或者至少一个目标参数标识、或者至少一个目标TCI等。
步骤203、UE根据目标信息，从信道配置信息集合中确定与目标信息对应的目标传输参数。
其中，上述信道配置信息集合是网络设备在向UE指示目标信息之前，为UE预先配置的。信道配置集合对应多个TRP的传输参数，目标传输参数为这多个TRP中一个TRP的传输参数。也就是说，网络设备通过信道配置集合为终端配置多个TRP的传输参数，当为终端服务的TRP发生变更时，终端可根据网络设备发送的目标信息，从信道配置集合中选择对应TRP的传输参数。其中，目标信息中可以携带用于指示变更后TRP的指示信息。
可选地，本公开实施例中，网络设备可以通过RRC信令，将信道配置信息集合配置给UE。
步骤204、UE根据目标传输参数，发送或接收目标信道。
步骤205、网络设备根据目标传输参数，接收或发送目标信道。
具体的，本公开实施例中，在网络设备发送目标信道的情况下，UE接收该目标信道；在UE发送目标信道的情况下，网络设备接收该目标信道。具体可以根据实际使用需求确定，本公开实施例不作限定。本公开实施例提供的信道传输方法包括信道的接收、发送、搜索、检测或监听等。
需要说明的是，本公开实施例可以不限定步骤204和步骤205的执行顺序。即本公开实施例可以先执行步骤204，后执行步骤205；也可以先执行步骤205，后执行步骤204；还可以同时执行步骤204和步骤205。可以理解，上述图2是以先执行步骤205后执行步骤204为例示意的。
可选地，本公开实施例中，上述目标信道可以为以下任意一项：PUCCH、PDCCH、PUSCH、PDSCH。
为了便于描述，PDCCH配置信息可以记为PDCCH-Config，PDSCH配置信息可以记为PDSCH-Config，PUCCH配置信息可以记为PUCCH-Config，PUSCH配置信息可以记为PUSCH-Config。
可选地，本公开实施例中，上述信道配置信息集合可以包括多个信道配置信息，或者可以包括一个信道配置信息，本公开实施例提供的信道传输方法在这两种情况下的具体实现方式不同。
下面通过第一实现方式和第二实现方式，分别描述在信道配置信息集合包括多个信道配置信息的情况下信道传输方法的具体实现方式，以及在信道配置信息集合包括一个信道配置信息的情况下信道传输方法的具体实现方式。
第一实现方式
在第一实现方式中，上述信道配置信息集合可以包括多个信道配置信息。例如，上述信道配置信息集合可以包括以下中至少一项：多个PDCCH-Config、多个PDSCH-Config、多个PUCCH-Config、多个PUSCH-Config。
下面示例性的说明各个信道配置信息(即PDCCH-Config、PDSCH-Config、PUCCH-Config和PUSCH-Config)分别可能包括的传输参数。
示例性的，PDCCH-Config可以包括控制资源集(Control Resource Set，CORESET)、TCI等传输参数。
示例性的，PDSCH-Config可以包括扰码参数等传输参数。
示例性的，PUCCH-Config可以包括PUCCH资源集(PUCCH resource set)、功率控制参数等传输参数。
示例性的，PUSCH-Config可以包括功率控制参数。
本公开实施例中，在上述信道配置信息集合包括多个信道配置信息的情况下，每个信道配置信息包括的传输参数可以对应一个TRP集合。
其中，该TRP集合可以包括至少一个TRP，例如一个TRP，或者两个TRP，或者两个以上的TRP，具体可以根据实际使用需求确定，本公开实施例不作限定。
为了便于说明，下文中以网络设备为UE预先配置多个PDCCH-Config为例，示例性的说明本公开实施例提供的信道传输方法。
举例来说，以PDCCH-Config的传输参数为CORESET为例，由于PDCCH-Config的传输参数CORESET与TRP相关联，因此根据CORESET与TRP的关联关系，可以确定PDCCH-Config与TRP之间的对应关系。
其中，不同的PDCCH-Config可以利用不同的ID进行区分，例如PDCCH-Config ID0、PDCCH-Config ID1、PDCCH-Config ID2、PDCCH-Config ID3分别可以指示四个不同的信道配置信息。每个PDCCH-Config内不同的CORESET可以具有不同的标识进行区分，例如CORESET ID1、CORESET ID2分别可以指示两个不同的CORESET。另外，不同的TRP也可以利用不同的ID进行区分，例如TRP ID0、TRP ID1、TRP ID2分别可以指示三个不同的TRP。可以通过配置CORESET ID对应的TRP ID确定CORESET与TRP的关联关系。
示例性的，假设PDCCH-Config ID0指示的PDCCH-Config包括两个CORESET(分别由CORESET ID1和CORESET ID2指示)，其中，这两个CORESET分别对应不同的TRP，例如CORESET ID1指示的CORESET可以与TRP ID0指示的TRP关联，CORESET ID2指示的CORESET可以与TRP ID1指示的TRP关联。那么，PDCCH-Config 0指示的 PDCCH-Config的传输参数可以对应TRP ID0和TRP ID1各自指示的TRP(即上述的一个TRP集合)，如下述的表1所示。
需要说明的是，TRP标识的作用是区分不同的TRP。可选地，本公开实施例中，TRP标识可以是高层信令配置的一个标识，或者是实际的TRP标识，或小区标识等，具体可以根据实际使用需求确定，本公开实施例不作限定。
表1
Figure PCTCN2020103063-appb-000001
本公开实施例中，基于每个信道配置信息包括的传输参数可以对应一个TRP集合，可以理解，每个信道配置信息可以对应一个TRP集合，例如一个PDCCH-Config可以对应一个TRP，或者对应两个TRP，或者对应两个以上TRP。示例性的，参照上述的表1所示，PDCCH-Config 0指示的PDCCH-Config可以对应TRP ID0和TRP ID1各自指示的TRP(即上述的一个TRP集合)。
可选地，本公开实施例中，在上述信道配置信息集合包括多个信道配置信息的情况下，(1)该多个信道配置信息可以在一个带宽部分(Bandwidth Part，BWP)配置信息内；或者(2)该多个信道配置信息可以在多个BWP配置信息内，且每个BWP配置信息可以包括该多个信道配置信息中的至少一个信道配置信息。
下面分别通过下述的方式一和方式二，分别描述在上述情况(2)时本公开实施例提供的信道传输方法的具体实现方式，以及在情况(2)时本公开实施例提供的信道传输方法的具体实现方式。
方式一：
可选地，在上述信道配置信息集合包括多个信道配置信息，且该多个信道配置信息在一个BWP配置信息内的情况下，上述目标信息可以为目标信道配置信息标识，或者可以为至少一个目标TRP标识。
可选地，在一种可能的实现方式中，假设上述目标信息为目标信道配置信息标识，那么，上述的步骤203具体可以通过下述的步骤203a和步骤203b实现。
步骤203a、UE根据目标信道配置信息标识，从多个信道配置信息中确定与目标信道配置信息标识对应的第一信道配置信息。
步骤203b、UE将第一信道配置信息中的传输参数确定为目标传输参数。
示例性的，在UE接收到网络设备指示的PDCCH-Config ID(即上述目标信息)之后，UE可以根据PDCCH-Config ID，从多个PDCCH-Config中确定与PDCCH-Config ID对应的PDCCH-Config，并将该PDCCH-Config中的传输参数(例如至少包括CORESET等参 数)确定为目标传输参数。进而，UE可以根据该目标传输参数，接收PDCCH。
可选地，在另一种可能的实现方式中，假设上述目标信息为至少一个目标TRP标识，那么，上述的步骤203具体可以通过下述的步骤203c和步骤203d实现。
步骤203c、UE根据目标TRP标识，从多个信道配置信息中确定与目标TRP标识对应的第一信道配置信息。
步骤203d、UE将第一信道配置信息中的传输参数确定为目标传输参数。
示例性的，在UE接收到网络设备指示的TRP ID(即上述目标信息)之后，UE可以根据TRP ID，从多个PDCCH-Config中确定与TRP ID对应的PDCCH-Config，并将该PDCCH-Config中的传输参数(例如至少包括CORESET等参数)确定为目标传输参数。进而，UE可以根据该目标传输参数，接收PDCCH。
举例来说，假设目标小区(cell)包含5个TRP(TRP ID0～TRP ID4)，一个UE最多支持5个CORESET，且最多支持2个TRP为该UE传输。网络设备通过RRC信令为UE预先配置多个PDCCH-Config。其中，多个PDCCH-Config可以包括至少一个包含一个CORESET组标识(例如TRP ID)或者没有配置CORESET组标识的PDCCH-Config、至少一个包含两个CORESET组标识的PDCCH-Config等。
需要说明的是，假设CORESET ID1和CORESET ID2各自指示的CORESET均与TRP ID0指示的TRP关联，那么，CORESET ID1和CORESET ID2可以称为属于一个CORESET组(group)，该CORESET组的标识可以对应理解为TRP ID0。
下述的表2示例性地示出了PDCCH-Config与TRP集合的对应关系。
表2
PDCCH-Config ID CORESET关联的TRP ID
0 TRP ID0，TRP ID1
1 TRP ID0，TRP ID2
2 TRP ID0，TRP ID3
3 TRP ID0，TRP ID4
4 TRP ID1，TRP ID2
5 TRP ID1，TRP ID4
6 TRP ID2，TRP ID3
7 TRP ID3，TRP ID4
8 TRP ID4
当UE进入目标小区时，网络设备可以通过RRC信令，将一个BWP配置信息内的所有或部分PDCCH-Config配置给该UE。然后，网络设备可以通过MAC CE，向UE指示当前使用的PDCCH-Config ID，UE则使用该PDCCH-Config ID对应的PDCCH-Config配置 参数(例如CORESET)接收PDCCH。并且，在为UE提供服务的TRP发生变更的情况下，网络设备同样可以通过MAC CE，向UE指示新使用的PDCCH-Config ID，相应地，UE可以使用该PDCCH-Config ID对应的PDCCH-Config配置参数(例如CORESET)接收PDCCH。
示例性的，结合上述的表2，当网络设备确定TRP ID0和TRP ID3对应的TRP为该UE服务时，网络设备可以通过MAC CE，向UE指示PDCCH-Config ID2(即上述目标信息)；相应地，UE可以使用该PDCCH-Config ID2对应的PDCCH-Config配置参数(例如至少包括CORESET等参数)，接收PDCCH。
又示例性的，结合上述的表2，当网络设备确定仅由TRP ID4对应的TRP为该UE服务时，网络设备可以通过MAC CE，向UE指示PDCCH-Config ID3、PDCCH-Config ID5、PDCCH-Config ID7或PDCCH-Config ID8中的任意一个(即上述目标信息)；相应地，UE可以使用指示的该PDCCH-Config ID对应的PDCCH-Config配置参数(例如至少包括CORESET等参数)，接收PDCCH。
再示例性的，结合上述的表2，当网络设备确定TRP ID0和TRP ID3对应的TRP为该UE服务时，网络设备可以通过MAC CE，向UE指示TRP ID0和TRP ID3(即上述目标信息)；相应地，UE可以根据TRP ID0和TRP ID3确定对应的PDCCH-Config ID2，并使用该PDCCH-Config ID2对应的PDCCH-Config配置参数(例如至少包括CORESET等参数)，接收PDCCH。
需要说明的是，表2中PDCCH-Config的数量以及每个PDCCH-Config对应的TRP的数量为示例性的列举，具体可以根据实际使用需求确定，本公开实施例不作限定。
还需要说明的是，基于各个TRP与UE的位置关系(例如两个TRP距离较远或之间隔着另一个TRP)，一个小区内的某两个或多个TRP可能无法同时服务一个UE。例如，如果TRP ID1和TRP ID3各自对应的TRP距离较远，那么这两个TRP几乎不可能同时服务一个UE；如果TRP ID2和TRP ID4各自对应的TRP之间隔着另一个TRP，那么TRP ID2和TRP ID4各自对应的TRP几乎不可能同时服务一个UE。网络设备可以不配置这些不可能的信道配置信息。例如表2中没有配置TRP ID1和TRP ID3对应的PDCCH-Config，也没有配置TRP ID2和TRP ID4对应的PDCCH-Config。
本公开实施例中，与相关技术中TRP发生变更后，通过RRC信令重配置(重配置时间较长)相比，本公开实施例通过MAC CE向UE指示目标信息，从网络设备预先配置给UE的信道配置信息集合中确定目标传输参数，进而可以根据目标传输参数，传输目标信道，如此可以实现在TRP发生变更后快速重配置信道配置信息，保证通信质量连续性。
方式二
可选地，在上述信道配置信息集合包括多个信道配置信息，且该多个信道配置信息在多个BWP配置信息内(例如多个PDCCH-Config分别在多个BWP配置信息内)的情况下， 上述目标信息可以为目标BWP标识。该目标BWP标识可以用于指示UE切换到与目标BWP标识对应的BWP。
可选地，本公开实施例中，网络设备可以通过DCI信令向UE发送目标BWP标识，指示UE切换BWP，或者可以通过RRC信令配置定时器，指示UE在生效时间后切换BWP。
本公开实施例中，由于网络设备配置多个下行BWP(BWP-Downlink)配置信息，每个下行BWP配置信息中包含的PDCCH-Config、PDSCH-Config可以对应至少一个TRP ID，因此，通过网络设备指示UE切换BWP，意味着为UE切换TRP。
示例性的，本公开实施例中，假设上述目标信息为目标BWP标识，那么，上述的步骤203具体可以通过下述的步骤203e和步骤203f实现。
步骤203e、UE根据目标BWP标识，确定与目标BWP标识对应的至少一个第二信道配置信息。
步骤203f、UE将至少一个第二信道配置信息中的传输参数确定为目标传输参数。
示例性的，本公开实施例中，UE可以根据BWP ID，确定BWP ID对应的BWP配置信息；然后可以将该BWP配置信息中的至少一个信道配置信息(例如多个PDCCH-Config：PDCCH-Config ID0和PDCCH-Config ID1)，确定为至少一个第二信道配置信息；并将该至少一个第二信道配置信息中的传输参数(例如至少包括CORESET等参数)确定为目标传输参数。进而，UE可以根据该目标传输参数，接收PDCCH。
本公开实施例中，通过网络设备指示UE切换BWP，意味着为UE切换TRP，如此可以实现在TRP发生变更后的快速重配置。
第二实现方式
在第二实现方式中，上述信道配置信息集合可以包括一个信道配置信息，例如上述信道配置信息集合可以包括以下中任一项：一个PDCCH-Config、一个PDSCH-Config、一个PUCCH-Config、一个PUSCH-Config。其中，该一个信道配置信息包括的传输参数对应UE所在小区中的全部TRP或部分TRP。
对于信道配置信息包括的传输参数的具体描述，可以参见上述实施例的第一实现方式中对信道配置信息包括的传输参数的相关描述，此处不再赘述。
可选地，本公开实施例中，在上述信道配置信息集合包括一个信道配置信息的情况下，上述目标信息可以包括以下任意一项：至少一个目标TRP ID、至少一个目标参数标识、至少一个目标TCI。
其中，上述目标参数标识可以为扰码参数标识，或者为功率控制参数标识，或者为其它任意满足实际使用需求的参数标识，具体可以根据实际使用需求确定，本公开实施例不作限定。
为了便于说明，下文中以网络设备为UE预先配置一个PDCCH-Config为例，示例性的说明本公开实施例提供的信道传输方法。
具体的，在通过RRC信令配置的一个PDCCH-Config内给出UE所在小区内所有TRP可能的CORESET配置，通过MAC CE指示UE将要在生效时间后使用的CORESET组标识或者属于这些CORESET组标识的CORESET。
即，网络设备仅为UE配置一个PDCCH-Config，该PDCCH-Config包含与UE所在小区内所有TRP关联的可能的CORESET(全部CORESET或部分CORESET)。
举例来说，当UE进入目标小区(包括5个TRP：TRP ID0～TRP ID4)时，网络设备通过RRC信令为UE配置一个PDCCH-Config，该PDCCH-Config内可以包含与5个TRP关联的CORESET。下述的表3示例性地示出了PDCCH-Config内，与UE所在小区内所有TRP关联的所有CORESET。
表3

2 TRP ID0
3 TRP ID1
4 TRP ID1
5 TRP ID2

7 TRP ID3

9 TRP ID4
10 TRP ID4
下面分别针对目标信息包括至少一个目标TRP ID、目标信息包括至少一个目标参数标识、目标信息包括至少一个目标TCI，分别说明本公开实施例提供的信道传输方法的具体实现方式。
(1)可选地，本公开实施例中，假设上述目标信息包括至少一个目标TRP ID，那么，上述的步骤203具体可以通过下述的步骤203g实现。
步骤203g、UE将一个信道配置信息包括的传输参数中，与至少一个目标TRP ID对应的传输参数确定为目标传输参数。
示例性的，结合上述的表3，假设网络设备为UE预先配置一个PDCCH-Config，那么在UE接收到网络设备指示的TRP ID0(即上述目标信息)之后，UE可以将PDCCH-Config包括的传输参数中，与TRP ID0对应的传输参数CORESET ID0和CORESET ID1确定为目标传输参数。
具体的，在网络设备通过MAC CE向UE指示当前使用的TRP ID之后，UE可以根据 该TRP ID关联的所有CORESET上接收PDCCH。例如，结合上述的表3，当网络设备确定TRP ID0和TRP ID3对应的TRP为该UE服务时，网络设备通过MAC CE向UE指示TRP ID0和TRP ID3，UE则在CORESET ID1、2、7、8上搜索可能的PDCCH。例如，结合上述的表3，当网络设备确定仅由TRP ID4对应的TRP为该UE服务时，网络设备通过MAC CE向UE指示TRP ID4，UE则在CORESET ID9、10上搜索可能的PDCCH。
或者，在网络设备通过MAC CE向UE指示当前使用的CORESET ID之后，UE可以在这些CORESET上搜索PDCCH。例如，结合上述的表3，当网络设备确定TRP ID0和TRP ID3对应的TRP为该UE服务时，网络设备通过MAC CE向UE指示CORESET ID1、2、7、8或者其中的部分，UE在所指示的这些CORESET上搜索可能的PDCCH。例如，结合上述的表3，当网络设备确定仅由TRP ID4对应的TRP为该UE服务时，网络设备通过MAC CE向UE指示CORESET ID9、10或其中的部分，UE在所指示的这些CORESET上搜索可能的PDCCH。
(2)可选地，本公开实施例中，假设上述目标信息包括至少一个目标参数标识，那么，上述的步骤203具体可以通过下述的步骤203h实现。
步骤203h、UE将一个信道配置信息包括的传输参数中，与至少一个目标参数标识对应的传输参数确定为目标传输参数。
示例性的，假设网络设备为UE预先配置一个PDSCH-Config，那么在UE接收到网络设备指示的扰码参数标识(即上述目标信息)之后，UE可以将PDSCH-Config包括的传输参数中，与扰码参数标识对应的传输参数确定为目标传输参数。
(3)可选地，本公开实施例中，假设上述目标信息包括至少一个目标TCI，那么，上述的步骤203具体可以通过下述的步骤203i实现。
步骤203i、UE将一个信道配置信息包括的传输参数中，与至少一个目标TCI对应的传输参数确定为目标传输参数。
本公开实施例中，在一个小区的多TRP场景下，网络设备为UE配置一个PDCCH-Config、PDSCH-Config，网络设备可以通过MAC CE，向UE指示CORESET使用的TCI，通过将一个信道配置信息包括的传输参数中，与TCI对应的传输参数(例如CORESET)确定为目标传输参数，从而可以实现TRP选择和切换。
本公开实施例提供的信道传输方法，可以根据目标信息，从信道配置信息集合中确定与该目标信息对应的目标传输参数；并根据该目标传输参数，发送或接收目标信道；其中，目标信息是网络设备用于指示变更为UE提供服务的TRP；信道配置信息集合是网络设备在向UE指示目标信息之前，为UE预先配置的。与相关技术中TRP发生变更后，通过RRC信令重配置(重配置时间较长)相比，本公开实施例通过MAC CE向UE指示目标信息，从网络设备预先配置给UE的信道配置信息集合中确定目标传输参数，进而可以根据目标传输参数，传输目标信道，如此可以实现在TRP发生变更后快速重配置信道配置信息，保 证通信质量连续性。
可选地，结合图2，如图3所示，在上述的步骤201之前，本公开实施例提供的信道传输方法还可以包括下述的步骤206。
步骤206、网络设备根据第一TRP，确定目标信息。
其中，该第一TRP为网络设备确定的为UE提供服务的TRP。
本公开实施例提供的信道传输方法，与相关技术中TRP发生变更后，通过RRC信令重配置(重配置时间较长)相比，本公开实施例通过MAC CE向UE指示目标信息，从网络设备预先配置给UE的信道配置信息集合中确定目标传输参数，进而可以根据目标传输参数，传输目标信道，如此可以实现在TRP发生变更后快速重配置信道配置信息，保证通信质量连续性。
