Description

默认波束的确定方法、装置、用户设备及网络设备 技术领域
本申请涉及无线通信技术领域，尤其涉及一种默认波束的确定方法、装置、用户设备、网络设备及存储介质。
背景技术
在新空口(New Radio，NR)系统中，由于高频信道衰减较快，为了保证覆盖范围，可以使用基于波束的发送和接收。当网络设备有多个TRP(Transmission and Reception Point，发送接收点)时，网络设备可以使用多个TRP为用户设备提供服务，比如使用多个TRP为用户设备发送PDCCH(Physical Downlink Control Channel，物理下行控制信道)。网络设备使用一个TRP为用户设备发送PDCCH时，可以为用户设备配置一个CORESET(ControlResourceSet，控制资源集)，并配置该CORESET对应的一个TCI(Transmission Configuration Indication，传输配置指示)状态；网络设备使用多个TRP为用户设备发送PDCCH时，可以为该CORESET配置多个TCI状态，分别用于指示对应不同的TRP的波束。
相关技术中，对于当PDCCH与PDCCH上携带的DCI(Downlink Control Information，下行控制信息)信令调度的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的时间间隔较小时，用户设备来不及获得DCI中的波束指示信息时，或DCI中没有携带用于指示PDSCH的接收波束对应的TCI状态时，用户设备就需要使用默认波束去接收DCI调度的PDSCH。但是，现有技术中，确定默认波束的方式都是针对发送DCI的CORESET对应一个TCI状态而定义的，当发送DCI的CORESET对应多个TCI状态时，无法确定该CORESET对应的默认波束。

本申请实施例针对相关技术中，当发送DCI的CORESET对应多个TCI状态时，无法确定该CORESET对应的默认波束的问题，提出一种默认波束的确定方法。
本申请实施例提供的默认波束的确定方法，通过基于指定的规则，确定第一CORESET对应的默认波束，其中，第一CORESET支持的TCI状态的最大数目大于或等于2。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
下面参考附图对本申请提供的默认波束的确定方法、装置、用户设备、网络设备及存储介质进行详细描述。
图1为本申请实施例所提供的一种默认波束的确定方法的流程示意图，应用于用户设备。
如图1所示，该默认波束的确定方法，包括以下步骤：
步骤101，基于指定的规则，确定第一CORESET对应的默认波束，其中，所述第一CORESET支持的TCI状态的最大数目大于或等于2。
需要说明的是，本申请实施例的默认波束的确定方法可以应用在任意的用户设备中。用户设备可以是指向用户提供语音和/或数据连通性的设备。用户设备可以经RAN(Radio Access Network，无线接入网)与一个或多个核心网进行通信，终端可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，STA(Station，站)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者，用户设备也可以是无人飞行器的设备。或者，用户设备也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，用户设备也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
需要说明的是，本申请实施例的默认波束的确定方法的应用场景可以包括：为可以配置多个TCI状态的CORESET确定默认波束的场景。其中，TCI状态即为波束，一个TCI状态可以与一个波束对应。
其中，第一CORESET，可以是指可以支持多个TCI状态的CORESET。需要说明的是，第一CORESET虽然可以支持多个TCI状态，但是根据实际业务需求在某些时刻也可以为其配置一个TCI状态，本申请实施例对此不做限定。
作为一种示例，第一CORESET可以是可以支持两个TCI状态的CORESET。需要说明的是，本申请的以下内容以第一CORESET为可以支持两个TCI状态的CORESET为例，进行具体说明。
作为一种可能的实现方式，可以将MAC CE(Medium Access Control Control Element，媒体接入控制控制单元)信令作为CORESET的波束指示信令，从而可以通过MAC CE信令确定第一CORESET对应的默认波束。即在本申请实施例一种可能的实现方式中，上述步骤101，可以包括：
接收MAC CE，MAC CE用于激活第一CORESET对应的第一波束；
将第一波束，确定为第一CORESET对应的默认波束。
在本申请实施例中，网络设备可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为第一CORESET激活的波束数量，并通过MAC CE激活相应数量的第一波束，从而用户设备可以根据 接收到的MAC CE确定激活的第一CORESET对应的第一波束，并将第一波束确定为第一CORESET对应的默认波束。
比如，网络设备中包含2个TRP，则网络设备可以确定第一波束的数量可以为1或2，从而网络设备可以通过向用户设备发送MAC CE，并为第一CORESET激活1个第一波束，或者为第一CORESET激活两个第一波束。需要说明的是，为第一CORESET激活两个第一波束时，每个第一波束分别与不同的TRP对应，其中，TRP可以通过TRP标识、CORESETPoolIndex(ControlResourceSetPoolIndex，控制资源集池索引)、参考信号资源标识、参考信号资源集标识、panel ID等中的至少一项进行区分。
需要说明的是，用户设备在根据第一波束确定第一CORESET对应的默认波束时，可以根据第一波束的数量以及预先设定的默认波束的数量，将相应的第一波束确定为第一CORESET对应的默认波束。可选的，可以分为以下三种情况：
情况一
第一波束的数量为一个，将一个第一波束确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，响应于第一波束的数量为一个，则用户设备可以直接将MAC CE为第一CORESET激活的一个第一波束，确定为第一CORESET对应的默认波束。
情况二
第一波束的数量为两个，将两个第一波束确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，响应于第一波束的数量为两个，且网络设备与用户设备预先约定的默认波束的数量为两个，或者未预先约定默认波束的数量，则用户设备可以直接将MAC CE为第一CORESET激活的两个第一波束，确定为第一CORESET对应的默认波束。
情况三
第一波束的数量为两个，将两个第一波束中与指定TRP对应的一个第一波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，MAC CE中可以包含多个比特位，分别用于激活不同TRP的TCI状态，且用户设备可以获知MAC CE中的每个比特位分别用于激活哪个TRP的TCI状态。从而，响应于第一波束的数量为两个，且网络设备与用户设备预先约定了指定TRP，则用户设备可以根据MAC CE中的每个比特位与TRP的对应关系，确定两个第一波束中指定TRP对应的第一波束，并将指定TRP对应的第一波束确定为第一CORESET对应的默认波束。
比如，若两个第一波束中，其中一个第一波束对应两个TRP中的TRP#0(或CORESETPoolIndex#0对应的TRP)，另一个第一波束对应两个TRP中的TRP#1(或CORESETPoolIndex#1)，则指定TRP可以为TRP#0(或CORESETPoolIndex#0对应的TRP)，指定TRP也可以为TRP#1(或CORESETPoolIndex#1对应的TRP)。
作为另一种可能的实现方式，还可以将DCI作为CORESET的波束指示信令，从而可以通过DCI确定第一CORESET对应的默认波束。即在本申请实施例一种可能的实现方式中，上述步骤101，可以包括：
接收第一DCI，第一DCI用于指示第一CORESET对应的第二波束；
将第二波束，确定为第一CORESET对应的默认波束。
在本申请实施例中，网络设备还可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为第一CORESET激活的波束数量，并通过向用户设备发送DCI为第一CORESET配置相应数量的第二波束，从而用户设备可以根据接收到的DCI确定第二波束，并将第二波束确定为CORESET对应的默认波束。
需要说明的是，DCI中用于指示波束的TCI状态域为多个比特(比如3bit)，多个比特不同时刻可以显示为多个不同的codepoint(码点)，比如‘000’、‘001’、‘010’、‘011’、‘100’、‘101’、‘110’和‘111’。并且每个codepoint可以与一组第二波束对应，其中，每组第二波束可以包括一个第二波束或者两个第二波束。
作为一种示例，codepoint与每组第二波束之间的对应关系可以由MAC CE来指示。即可以通过 MAC CE激活多个第二波束，并且MAC CE中的每个比特位分别与每个codepoint对应的两个第二波束一一对应，但每个codepoint对应的两个第二波束可以只有一个第二波束是存在的，并由MAC CE中的比特位信息进行指示；当每个codepoint对应的两个第二波束都存在时，两个第二波束分别对应不同的TRP。
需要说明的是，用户设备在根据第二波束确定第一CORESET对应的默认波束时，可以根据DCI中每个codepoint对应的第二波束的数量以及预先设定的默认波束的数量，将相应的第二波束确定为第一CORESET对应的默认波束。可选的，可以分为以下四种情况：
情况一
将第二波束中的至少一个，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，响应于第二波束的数量为一个，即DCI指示第一CORESET对应的波束为一个波束，则用户设备可以直接将DCI指示的一个第二波束，确定为第一CORESET对应的默认波束。
作为另一种可能的实现方式，响应于第二波束的数量为两个，即DCI指示第一CORESET对应的波束为两个波束，且指示第一CORESET对应的默认波束为一个，则用户设备可以将两个第二波束中的任意一个确定为第一CORESET对应的默认波束。
作为再一种可能的实现方式，响应于第二波束的数量为两个，即DCI指示第一CORESET对应的波束为两个波束，且指示第一CORESET对应的默认波束为两个，则用户设备可以将DCI指示的两个第二波束均确定为第一CORESET对应的默认波束。
情况二
将第一DCI中用于指示一个第二波束、且取值最小的codepoint对应的第二波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，由于DCI中的每个codepoint都可以对应一组第二波束，因此用户设备可以将其中一个codepoint对应的第二波束，确定为第一CORESET对应的默认波束。从而，响应于DCI指示第一CORESET对应的默认波束为一个，则用户设备可以首先选取出DCI中对应一个第二波束的codepoint，并将选取出的取值最小的codepoint对应的一个第二波束，确定为第一CORESET对应的默认波束。
举例来说，DCI中的每个codepoint可以通过3个比特位进行表示，如codepoint的取值可以包括000、001、010、011、100、101、110、111，等等，并且上述各个取值是按照从小到大的顺序排列的。比如，DCI中codepoint“011”对应一个第二波束，codepoint“000”也指示一个第二波束，则可以将codepoint“000”指示的一个第二波束确定为第一CORESET对应的默认波束。
情况三
将第一DCI中用于指示两个第二波束、且取值最小的codepoint对应的第二波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，由于DCI中的每个codepoint都可以对应一组第二波束，因此用户设备可以将其中一个codepoint对应的第二波束，确定为第一CORESET对应的默认波束。从而，响应于DCI指示第一CORESET对应的默认波束为两个，则用户设备可以首先选取出DCI中对应两个第二波束的codepoint，并将选取出的取值最小的codepoint对应的两个第二波束，确定为第一CORESET对应的默认波束。
举例来说，DCI中codepoint“011”对应两个第二波束，codepoint“000”也指示两个第二波束，则可以将codepoint“000”指示的两个第二波束确定为第一CORESET对应的默认波束。
情况四
将第一DCI中用于指示两个第二波束、且取值最小的codepoint对应的两个第二波束中与指定TRP对应的一个第二波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，由于DCI中的每个codepoint都可以对应一组第二波束，因此用户设备可以将其中一个codepoint对应的第二波束，确定为第一CORESET对应的默认波束。从而，响应于DCI 指示第一CORESET对应的波束为两个波束，且指示第一CORESET对应的默认波束为一个，并且网络设备与用户设备预先约定了指定TRP，则用户设备可以首先选取出DCI中对应两个第二波束的codepoint，可以根据MAC CE中的每个比特位与TRP的对应关系，确定选取出的取值最小的codepoint对应的两个第二波束中与指定TRP对应的第二波束，并将指定TRP对应的第二波束确定为第一CORESET对应的默认波束。
举例来说，DCI中codepoint“011”对应两个第二波束，codepoint“000”也指示两个第二波束，而且“000”指示的两个第二波束分别为TCI#0和TCI#1，其中TCI#0对应TRP#0(或CORESETPoolIndex#0对应的TRP)，其中TCI#1对应TRP#1(或CORESETPoolIndex#1对应的TRP)。若指定TRP为TRP#0(或CORESETPoolIndex#0对应的TRP)，则将TCI#0确定为第一CORESET对应的默认波束；若指定TRP为TRP#1(或CORESETPoolIndex#1对应的TRP)，则将TCI#1确定为第一CORESET对应的默认波束。
在本申请实施例中，MAC CE可以为指示第一CORESET的专用波束的MAC CE；或者，MAC CE也可以为指示包含第一CORESET在内的一个group(集合)的通用波束的MAC CE。
其中，group中除了可以包含第一CORESET之外，还可以包含其它CORESET、PDSCH、PUSCH(physical uplink shared channel，物理上行共享信道)、PUCCH(physical uplink control channel，物理上行控制信道)、CSI-RS(channel state information reference signal，信道状态信息参考信号)、SRS(sounding reference signal，探测参考信号)、PRS(Positioning Reference Signal，定位参考信号)、DMRS(Demodulation Reference Signal，解调参考信号)等中的至少一项。
需要说明的是，专用波束可以是指只用于第一CORESET的波束；通用波束可以是指可以用于至少一组信道和/或至少一种参考信号的波束，即除了可以用于第一CORESET之外，还可以用于与第一CORESET属于一个group的其它CORESET、PDSCH、PUSCH、参考信号等。
本申请实施例提供的默认波束的确定方法，通过基于指定的规则，确定第一CORESET对应的默认波束，其中，第一CORESET支持的TCI状态的最大数目大于或等于2。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
下面结合图2，对本申请实施例提供的另一种默认波束的确定方法进行进一步说明。
图2为本申请实施例所提供的另一种默认波束的确定方法的流程示意图，应用于用户设备。
如图2所示，该默认波束的确定方法，包括以下步骤：
步骤201，确定最近一个需要检测PDCCH的时间单元中，索引取值最小的第二CORESET对应的第三波束。
其中，时间单元，可以是slot(时隙)、mini-slot(子时隙)、TTI(Transport Time Interval，传输时间间隔)、subframe(子帧)、无限帧中的任意一种，本申请实施例对此不做限定。本申请实施例中以时间单元为slot为例，进行具体说明。
在本申请实施例中，响应于所有CORESET均对应同一个CORESETPoolIndex，则用户设备可以确定最近一个需要检测PDCCH的slot中，索引取值最小的第二CORESET，并根据第二CORESET对应的第三波束，确定第一CORESET对应的默认波束。这种情况下，第一CORESET对应的CORESETPoolIndex可以为0、1、0和1，或除0和1以外的值，比如2、3、4。
步骤202，根据第三波束，确定默认波束。
在本申请实施例中，根据第二CORESET对应的第三波束，确定第一CORESET对应的默认波束时，可以根据第三波束的数量以及当前的业务需求，将第三波束中的一个或多个波束确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，可以确定第三波束为第一CORESET对应的默认波束。
可选的，响应于网络设备与用户设备未预先约定指定TRP，且第二CORESET最多只能配置一个波束，即第三波束的数量为一个，则可以将该第三波束确定为第一CORESET对应的默认波束。
可选的，响应于网络设备与用户设备未预先约定指定TRP，且第二CORESET最多可以配置两个波束，但当前只配置了一个波束，即第三波束的数量为一个，则可以将该第三波束确定为第一CORESET 对应的默认波束。
可选的，响应于网络设备与用户设备未预先约定指定TRP，且第二CORESET最多可以配置两个波束，并当前配置了两个波束，即第三波束的数量为两个，则可以将这两个第三波束确定为第一CORESET对应的默认波束。
作为另一种可能的实现方式，还可以确定第一CORESET对应的默认波束为第三波束中与指定TRP对应的一个波束。
可选的，响应于网络设备与用户设备预先约定了指定TRP，且第二CORESET最多可以配置两个波束，并当前配置了两个波束，即第三波束的数量为两个，则可以将与指定TRP对应的第三波束确定为第一CORESET对应的默认波束。
举例来说，若两个第三波束中，其中一个第三波束比如TCI#0对应两个TRP中的TRP#0(或CORESETPoolIndex#0对应的TRP)，另一个第三波束比如TCI#1对应两个TRP中的TRP#1(或CORESETPoolIndex#1)，则指定TRP可以为TRP#0(或CORESETPoolIndex#0对应的TRP)，指定TRP也可以为TRP#1(或CORESETPoolIndex#1对应的TRP)。若指定TRP为TRP#0(或CORESETPoolIndex#0对应的TRP)，则将TCI#0确定为第一CORESET对应的默认波束；若指定TRP为TRP#1(或CORESETPoolIndex#1对应的TRP)，则将TCI#1确定为第一CORESET对应的默认波束。
在本申请的实施例中，步骤201-202可以分别采用本申请的各实施例中的任一种方式实现，本申请实施例并不对此作出限定，也不再赘述。
本申请实施例提供的默认波束的确定方法，通过确定最近一个需要检测PDCCH的时间单元中，索引取值最小的第二CORESET对应的第三波束，进而根据第三波束，确定默认波束。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
下面结合图3，对本申请实施例提供的再一种默认波束的确定方法进行进一步说明。
图3为本申请实施例所提供的再一种默认波束的确定方法的流程示意图，应用于用户设备。
如图3所示，该默认波束的确定方法，包括以下步骤：
步骤301，确定第一CORESET对应的第一CORESETPoolIndex。
在本申请实施例中，响应于不同CORESET可以对应不同的CORESETPoolIndex，则用户设备可以根据与第一CORESET对应的第一CORESETPoolIndex相同的CORESET，确定第一CORESET对应的默认波束。因此，用户设备可以首先确定第一CORESET对应的第一CORESETPoolIndex，以根据第一CORESETPoolIndex确定与第一CORESET的CORESETPoolIndex相同的CORESET。
作为一种可能的实现方式，由于CORESETPoolIndex可以用于标识CORESET对应的TRP，因此可以根据第一CORESET对应的TRP，确定第一CORESET对应的第一CORESETPoolIndex。
举例来说，第一CORESET实际上可以与两个TRP对应，响应于第一CORESET与第一TRP对应，则可以确定第一CORESET对应的第一CORESETPoolIndex为第一指定值；响应于第一CORESET与第二TRP对应，则可以确定第一CORESET对应的第一CORESETPoolIndex为第二指定值；响应于第一CORESET同时与第一TRP和第二TRP对应，则可以确定第一CORESET对应的第一CORESETPoolIndex为第一指定值和第二指定值，或者还可以确定第一CORESET对应的第一CORESETPoolIndex为第一指定值与第二指定值之外的其他值。比如，第一指定值可以为0，第二指定值可以为1，其他值可以为2，本申请实施例对此不做限定。
步骤302，根据第一CORESETPoolIndex，确定最近一个需要检测PDCCH的时间单元中索引取值最小的第三CORESET对应的第四波束，其中，第三CORESET对应的CORESETPoolIndex与第一CORESET对应的CORESETPoolIndex相同。
在本申请实施例中，确定出第一CORESET对应的第一CORESETPoolIndex之后，用户设备可以确定最近一个需要检测PDCCH的时间单元中，索引取值最小的第三CORESET，并根据第三CORESET对应的第四波束，确定第一CORESET对应的默认波束，
步骤303，根据第四波束，确定默认波束。
在本申请实施例中，根据第三CORESET对应的第四波束，确定第一CORESET对应的默认波束时，可以根据第四波束的数量以及当前的业务需求，将第四波束中的一个或多个波束确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，可以确定第四波束为第一CORESET对应的默认波束。
可选的，响应于网络设备与用户设备未预先约定指定TRP，且第三CORESET最多只能配置一个波束，即第四波束的数量为一个，则可以将该第四波束确定为第一CORESET对应的默认波束。
可选的，响应于网络设备与用户设备未预先约定指定TRP，且第三CORESET最多可以配置两个波束，但当前只配置了一个波束，即第四波束的数量为一个，则可以将该第四波束确定为第一CORESET对应的默认波束。
可选的，响应于网络设备与用户设备未预先约定指定TRP，且第三CORESET最多可以配置两个波束，并当前配置了两个波束，即第四波束的数量为两个，则可以将这两个第四波束均确定为第一CORESET对应的默认波束。
作为另一种可能的实现方式，还可以确定第一CORESET对应的默认波束为第四波束中与指定TRP对应的一个波束。
可选的，响应于网络设备与用户设备预先约定了指定TRP，且第三CORESET最多可以配置两个波束，并当前配置了两个波束，即第四波束的数量为两个，则可以将与指定TRP对应的第四波束确定为第一CORESET对应的默认波束。
举例来说，若两个第四波束中，其中一个第四波束比如TCI#0对应两个TRP中的TRP#0(或CORESETPoolIndex#0对应的TRP)，另一个第四波束比如TCI#1对应两个TRP中的TRP#1(或CORESETPoolIndex#1)，则指定TRP可以为TRP#0(或CORESETPoolIndex#0对应的TRP)，指定TRP也可以为TRP#1(或CORESETPoolIndex#1对应的TRP)。若指定TRP为TRP#0(或CORESETPoolIndex#0对应的TRP)，则将TCI#0确定为第一CORESET对应的默认波束；若指定TRP为TRP#1(或CORESETPoolIndex#1对应的TRP)，则将TCI#1确定为第一CORESET对应的默认波束。
进一步的，由于第一CORESET对应的第一CORESETPoolIndex或TPR标识，可以用于标识第一CORESET对应的TRP，因此，还可以根据第一CORESETPoolIndex或TRP标识的取值从第四波束中选取与第一CORESET对应的TRP对应的波束，确定为第一CORESET对应的默认波束。即在本申请实施例一种可能的实现方式中，上步骤303，可以包括：
将第一指定值对应的第四波束，确定为默认波束；
或者，
将第二指定值对应的第四波束，确定为默认波束；
或者，
将第一指定值及第二指定值分别对应的至少一个第四波束，确定为默认波束。
需要说明的是，本申请实施例中的第一指定值与第二指定值，可以是指CORESETPoolIndex的取值或者TRP标识的取值，本申请实施例对此不做限定。为便于理解，以下以第一指定值与第二指定值为CORESETPoolIndex的取值为例，进行具体说明。
可选的，响应于第一CORESETPoolIndex为第一指定值，比如第一指定值为0(或对应TRP#0)，则用户设备可以将第三CORESET对应的第四波束中第一指定值对应的第四波束，确定为第一CORESET对应的默认波束。
可选的，响应于第一CORESETPoolIndex为第二指定值，比如第二指定值为1(或对应TRP#1)，则用户设备可以将第三CORESET对应的第四波束中第二指定值对应的第四波束，确定为第一CORESET对应的默认波束。
可选的，响应于第一CORESETPoolIndex为第一指定值与第二指定值，比如第一指定值为0(或对应TRP#0)和第二指定值为1(或对应TRP#1)，则用户设备可以根据预先配置的默认波束的数量以及各指定值对应的第四波束的数量，将第一指定值及第二指定值对应的至少一个第四波束，确定为第一CORESET对应的默认波束。
作为一种示例，网络设备与用户设备可以预先约定第一CORESET对应的默认波束的数量为一个或两个，则响应于最近一个需要检测PDCCH的时间单元中的所有CORESET中仅存在CORESETPoolIndex为第一指定值的第三CORESET，则用户设备可以将第一指定值对应的第四波束确定为第一CORESET对应的默认波束；或者，响应于最近一个需要检测PDCCH的时间单元中的所有CORESET中仅存在CORESETPoolIndex为第二指定值的第三CORESET，则用户设备可以将第二指定值对应的第四波束确定为第一CORESET对应的默认波束。
作为一种示例，响应于最近一个需要检测PDCCH的时间单元中的所有CORESET中既存在CORESETPoolIndex为第一指定值的第三CORESET，又存在CORESETPoolIndex为第二指定值的第三CORESET，则用户设备可以响应于默认波束的数量为两个，将第一指定值及第二指定值对应的第四波束均确定为第一CORESET对应的默认波束；响应于默认波束的数量为一个，且网络设备与用户设备预先约定了指定TRP，则用户设备可以将指定TRP对应的第四波束确定为第一CORESET对应的默认波束。这种情况下，第一CORESET对应的CORESETPoolIndex可以为0、1、0和1，或除0和1以外的值，比如2、3、4。
在本申请的实施例中，步骤301-303可以分别采用本申请的各实施例中的任一种方式实现，本申请实施例并不对此作出限定，也不再赘述。
本申请实施例提供的默认波束的确定方法，通过确定第一CORESET对应的第一CORESETPoolIndex，并根据第一CORESETPoolIndex，确定最近一个需要检测PDCCH的时间单元中索引取值最小的第三CORESET对应的第四波束，其中，第三CORESET对应的CORESETPoolIndex与第一CORESET对应的CORESETPoolIndex相同，进而根据第四波束，确定默认波束。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
下面结合图4，对本申请实施例提供的又一种默认波束的确定方法进行进一步说明。
图4为本申请实施例所提供的又一种默认波束的确定方法的流程示意图，应用于用户设备。
如图4所示，该默认波束的确定方法，包括以下步骤：
步骤401，确定最近一个需要检测PDCCH的时间单元中对应CORESETPoolIndex为第三指定值、且索引取值最小的第四CORESET对应的第五波束。
作为一种可能的实现方式，响应于网络设备与用户设备预先约定第一CORESET对应的默认波束的数量为两个，用户设备还可以分别确定第一CORESET对应的两个默认波束。从而，用户设备可以根据第三指定值，从最近一个需要检测PDCCH的时间单元中的所有CORESET中，选取CORESETPoolIndex为第三指定值、且索引取值最小的第四CORESET，并确定第四CORESET对应的第五波束。比如，第三指定值可以为0，即对应第一TRP即TRP#0。
步骤402，确定最近一个需要检测PDCCH的时间单元中对应CORESETPoolIndex为第四指定值、且索引取值最小的第五CORESET对应的第六波束。
在本申请实施例中，确定出第四CORESET对应的第五波束之后，用户设备可以根据第四指定值，从最近一个需要检测PDCCH的时间单元中的所有CORESET中，选取CORESETPoolIndex为第四指定值、且索引取值最小的第五CORESET，并确定第五CORESET对应的第六波束。比如，第四指定值可以为1，即对应第二TRP即TRP#1。
需要说明的是，第四CORESET对应的时间单元与第五CORESET对应的时间单元，可以是不同的时间单元，以保证用户设备可以确定出两个默认波束。
步骤403，将第五波束及第六波束，确定为默认波束。
在本申请实施例中，确定出第四CORESET对应的第五波束与第五CORESET对应的第六波束之后，可以将第五波束与第六波束确定为第一CORESET对应的两个默认波束。这种情况下，第一CORESET对应的CORESETPoolIndex可以为0和1，或除0和1以外的值，比如2、3、4。即表明第一CORESET对应两个TCI状态，每个TCI状态对应两个TRP中的其中一个。
在本申请的实施例中，步骤401-403可以分别采用本申请的各实施例中的任一种方式实现，本申请 实施例并不对此作出限定，也不再赘述。
本申请实施例提供的默认波束的确定方法，通过确定最近一个需要检测PDCCH的时间单元中对应CORESETPoolIndex为第三指定值、且索引取值最小的第四CORESET对应的第五波束，并确定最近一个需要检测PDCCH的时间单元中对应CORESETPoolIndex为第四指定值、且索引取值最小的第五CORESET对应的第六波束，进而将第五波束及第六波束，确定为默认波束。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
下面结合图5，对本申请实施例提供的又一种默认波束的确定方法进行进一步说明。
图5为本申请实施例所提供的又一种默认波束的确定方法的流程示意图，应用于用户设备。
如图5所示，该默认波束的确定方法，包括以下步骤：
步骤501，接收网络设备发送的配置信令，其中，配置信令用于配置第二CORESET、第三CORESET、第四CORESET、第五CORESET中至少一个CORESET，以及至少一个CORESET中每个CORESET对应的一个或多个波束。
其中，配置信令，可以包括MAC CE和/或DCI。
在本申请实施例中，网络设备可以通过MAC CE与DCI中的至少一种，配置各个CORESET以及各个CORESET对应的一个或多个波束。
作为一种可能的实现方式，网络设备通MAC CE配置至少一个CORESET及其对应的波束时，网络设备可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为至少一个CORESET激活的波束数量，并通过MAC CE激活相应数量的波束，从而用户设备可以根据接收到的MAC CE确定至少一个CORESET对应的一个或多个波束。
作为一种可能的实现方式，网络设备通DCI配置至少一个CORESET及其对应的波束时，网络设备还可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为至少一个CORESET激活的波束数量，并通过向用户设备发送DCI为至少一个CORESET配置相应数量的波束，从而用户设备可以根据接收到的DCI确定至少一个CORESET对应的一个或多个波束。
需要说明的是，DCI中用于指示波束的TCI状态指示域在不同时刻可以显示为多个不同的codepoint(码点)，并且每个codepoint可以与一组波束对应，其中，每组波束可以包括一个或者两个波束。并且，codepoint与每组波束之间的对应关系可以由MAC CE来指示，从而网络设备通过DCI配置至少一个CORESET及其对应的一个或多个波束时，配置信令中可以同时包含MAC CE与DCI。
步骤502，基于指定的规则，确定第一CORESET对应的默认波束，其中，所述第一CORESET支持的TCI状态的最大数目大于或等于2。
在本申请的实施例中，步骤502可以分别采用本申请的各实施例中的任一种方式实现，本申请实施例并不对此作出限定，也不再赘述。
步骤503，基于第一CORESET对应的默认波束，传输第一CORESET对应的数据和/或参考信号。
其中，第一CORESET对应的数据，可以包括第一CORESET对应的或是调度的下行数据、上行数据；第一CORESET对应的参考信号，可以包括第一CORESET对应的或是调度的下行参考信号、上行参考信号。
在本申请实施例中，第一CORESET对应的默认波束可以用于接收或发送第一CORESET对应的或是调度的下行数据、下行参考信号、上行数据、上行参考信号等，因此，确定出第一CORESET对应的默认波束之后，用户设备可以基于所述第一CORESET对应的默认波束，传输第一CORESET对应的或是调度的下行数据、下行参考信号、上行数据、上行参考信号等。第一CORESET对应的默认波束还可以用于免调度许可(UL configured grant free)的上行数据的发送。
作为一种示例，第一CORESET对应的默认波束可以用于PDSCH的接收。即在本申请实施例一种可能的实现方式中，上述第一CORESET对应的数据可以包括第一CORESET内的PDCCH上发送的第二DCI调度的PDSCH上承载的数据。
作为一种示例，第一CORESET对应的默认波束还可以用于PUSCH的发送。即在本申请实施例一 种可能的实现方式中，上述第一CORESET对应的数据可以包括第一CORESET内的PDCCH上发送的第三DCI调度的PUSCH上承载的数据。
作为一种示例，第一CORESET对应的默认波束还可以用于PRACH(Physical Random Access Channel，物理随机接入信道)、PUCCH、CSI-RS、SRS的发送或接收，即在本申请实施例一种可能的实现方式中，上述第一CORESET对应的数据可以包括PRACH、PUCCH、CSI-RS、SRS。
本申请实施例提供的默认波束的确定方法，通过接收网络设备发送的配置信令，其中，配置信令用于配置第二CORESET、第三CORESET、第四CORESET、第五CORESET中至少一个CORESET，以及至少一个CORESET中每个CORESET对应的一个或多个波束，并基于指定的规则，确定第一CORESET对应的默认波束，其中，所述第一CORESET支持的TCI状态的最大数目大于或等于2，进而基于第一CORESET对应的默认波束，传输第一CORESET对应的数据和/或参考信号。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
图6为本申请实施例所提供的另一种默认波束的确定方法的流程示意图，应用于网络设备。
如图6所示，该默认波束的确定方法，包括以下步骤：
步骤601，基于指定的规则，确定第一CORESET对应的默认波束，其中，第一CORESET支持的TCI状态的最大数目大于或等于2。
需要说明的是，本申请实施例的默认波束的确定方法的应用场景可以包括：为可以配置多个TCI状态的CORESET确定默认波束的场景。其中，TCI状态即为波束，一个TCI状态可以与一个波束对应。
其中，第一CORESET，可以是指可以支持多个TCI状态的CORESET。需要说明的是，第一CORESET虽然可以支持多个TCI状态，但是根据实际业务需求在某些时刻也可以为其配置一个TCI状态，本申请实施例对此不做限定。
作为一种示例，第一CORESET可以是可以支持两个TCI状态的CORESET。需要说明的是，本申请的以下内容以第一CORESET为可以支持两个TCI状态的CORESET为例，进行具体说明。
作为一种可能的实现方式，可以将MAC CE信令作为CORESET的波束指示信令，从而可以通过MAC CE信令确定第一CORESET对应的默认波束。即在本申请实施例一种可能的实现方式中，上述步骤601，可以包括：
发送MAC CE，MAC CE用于激活第一CORESET对应的第一波束；
将第一波束，确定为第一CORESET对应的默认波束。
在本申请实施例中，网络设备可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为第一CORESET激活的波束数量，并通过MAC CE激活相应数量的第一波束，并将第一波束确定为第一CORESET对应的默认波束。
比如，网络设备中包含2个TRP，则网络设备可以确定第一波束的数量可以为1或2，从而网络设备可以通过向用户设备发送MAC CE，并为第一CORESET激活1个第一波束，或者为第一CORESET激活两个第一波束。需要说明的是，为第一CORESET激活两个第一波束时，每个第一波束分别与不同的TRP对应，其中，TRP可以通过TRP标识、CORESETPoolIndex、参考信号资源标识、参考信号资源集标识、panel ID等中的至少一项进行区分。
需要说明的是，网络设备在根据第一波束确定第一CORESET对应的默认波束时，可以根据第一波束的数量以及预先设定的默认波束的数量，将相应的第一波束确定为第一CORESET对应的默认波束。可选的，可以分为以下三种情况：
情况一
第一波束的数量为一个，将一个第一波束确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，响应于第一波束的数量为一个，则网络设备可以直接将MAC CE为第一CORESET激活的一个第一波束，确定为第一CORESET对应的默认波束。
情况二
第一波束的数量为两个，将两个第一波束确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，响应于第一波束的数量为两个，且网络设备与用户设备预先约定的默认波束的数量为两个，或者未预先约定默认波束的数量，则网络设备可以直接将MAC CE为第一CORESET激活的两个第一波束，确定为第一CORESET对应的默认波束。
情况三
第一波束的数量为两个，将两个第一波束中与指定TRP对应的一个第一波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，MAC CE中可以包含多个比特位，分别用于激活不同TRP的TCI状态，且网络设备可以获知MAC CE中的每个比特位分别用于激活哪个TRP的TCI状态。从而，响应于第一波束的数量为两个，且网络设备与用户设备预先约定了指定TRP，则网络设备可以根据MAC CE中的每个比特位与TRP的对应关系，确定两个第一波束中指定TRP对应的第一波束，并将指定TRP对应的第一波束确定为第一CORESET对应的默认波束。
比如，若两个第一波束中，其中一个第一波束对应两个TRP中的TRP#0(或CORESETPoolIndex#0对应的TRP)，另一个第一波束对应两个TRP中的TRP#1(或CORESETPoolIndex#1)，则指定TRP可以为TRP#0(或CORESETPoolIndex#0对应的TRP)，指定TRP也可以为TRP#1(或CORESETPoolIndex#1对应的TRP)。
作为另一种可能的实现方式，还可以将DCI作为CORESET的波束指示信令，从而网络设备可以通过DCI确定第一CORESET对应的默认波束。即在本申请实施例一种可能的实现方式中，上述步骤601，可以包括：
发送第一DCI，第一DCI用于指示第一CORESET对应的第二波束；
将第二波束，确定为第一CORESET对应的默认波束。
在本申请实施例中，网络设备还可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为第一CORESET激活的波束数量，并通过向用户设备发送DCI为第一CORESET配置相应数量的第二波束，并将第二波束确定为CORESET对应的默认波束。
需要说明的是，DCI中用于指示波束的TCI状态域为多个比特(比如3bit)，多个比特不同时刻可以显示为多个不同的codepoint(码点)，比如‘000’、‘001’、‘010’、‘011’、‘100’、‘101’、‘110’和‘111’。并且每个codepoint可以与一组第二波束对应，其中，每组第二波束可以包括一个第二波束或者两个第二波束。
作为一种示例，codepoint与每组第二波束之间的对应关系可以由MAC CE来指示。即可以通过MAC CE激活多个第二波束，并且MAC CE中的每个比特位分别与每个codepoint对应的两个第二波束一一对应，但每个codepoint对应的两个第二波束可以只有一个第二波束是存在的，并由MAC CE中的比特位信息进行指示；当每个codepoint对应的两个第二波束都存在时，两个第二波束分别对应不同的TRP。
需要说明的是，网络设备在根据第二波束确定第一CORESET对应的默认波束时，可以根据DCI中每个codepoint对应的第二波束的数量以及预先设定的默认波束的数量，将相应的第二波束确定为第一CORESET对应的默认波束。可选的，可以分为以下四种情况：
情况一
将第二波束中的至少一个，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，响应于第二波束的数量为一个，即DCI指示第一CORESET对应的波束为一个波束，则网络设备可以直接将DCI指示的一个第二波束，确定为第一CORESET对应的默认波束。
作为另一种可能的实现方式，响应于第二波束的数量为两个，即DCI指示第一CORESET对应的波束为两个波束，且指示第一CORESET对应的默认波束为一个，则网络设备可以将两个第二波束中的任意一个确定为第一CORESET对应的默认波束。
作为再一种可能的实现方式，响应于第二波束的数量为两个，即DCI指示第一CORESET对应的波束为两个波束，且指示第一CORESET对应的默认波束为两个，则网络设备可以将DCI指示的两个 第二波束均确定为第一CORESET对应的默认波束。
情况二
将第一DCI中用于指示一个第二波束、且取值最小的codepoint对应的第二波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，由于DCI中的每个codepoint都可以对应一组第二波束，因此网络设备可以将其中一个codepoint对应的第二波束，确定为第一CORESET对应的默认波束。从而，响应于DCI指示第一CORESET对应的默认波束为一个，则网络设备可以首先选取出DCI中对应一个第二波束的codepoint，并将选取出的取值最小的codepoint对应的一个第二波束，确定为第一CORESET对应的默认波束。
举例来说，DCI中的每个codepoint可以通过3个比特位进行表示，如codepoint的取值可以包括000、001、010、011、100、101、110、111，等等，并且上述各个取值是按照从小到大的顺序排列的。比如，DCI中codepoint“011”对应一个第二波束，codepoint“000”也指示一个第二波束，则可以将codepoint“000”指示的一个第二波束确定为第一CORESET对应的默认波束。
情况三
将第一DCI中用于指示两个第二波束、且取值最小的codepoint对应的第二波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，由于DCI中的每个codepoint都可以对应一组第二波束，因此网络设备可以将其中一个codepoint对应的第二波束，确定为第一CORESET对应的默认波束。从而，响应于DCI指示第一CORESET对应的默认波束为两个，则网络设备可以首先选取出DCI中对应两个第二波束的codepoint，并将选取出的取值最小的codepoint对应的两个第二波束，确定为第一CORESET对应的默认波束。
举例来说，DCI中codepoint“011”对应两个第二波束，codepoint“000”也指示两个第二波束，则可以将codepoint“000”指示的两个第二波束确定为第一CORESET对应的默认波束。
情况四
将第一DCI中用于指示两个第二波束、且取值最小的codepoint对应的两个第二波束中与指定TRP对应的一个第二波束，确定为第一CORESET对应的默认波束。
作为一种可能的实现方式，由于DCI中的每个codepoint都可以对应一组第二波束，因此网络设备可以将其中一个codepoint对应的第二波束，确定为第一CORESET对应的默认波束。从而，响应于DCI指示第一CORESET对应的波束为两个波束，且指示第一CORESET对应的默认波束为一个，并且网络设备与用户设备预先约定了指定TRP，则网络设备可以首先选取出DCI中对应两个第二波束的codepoint，可以根据MAC CE中的每个比特位与TRP的对应关系，确定选取出的取值最小的codepoint对应的两个第二波束中与指定TRP对应的第二波束，并将指定TRP对应的第二波束确定为第一CORESET对应的默认波束。
举例来说，DCI中codepoint“011”对应两个第二波束，codepoint“000”也指示两个第二波束，而且“000”指示的两个第二波束分别为TCI#0和TCI#1，其中TCI#0对应TRP#0(或CORESETPoolIndex#0对应的TRP)，其中TCI#1对应TRP#1(或CORESETPoolIndex#1对应的TRP)。若指定TRP为TRP#0(或CORESETPoolIndex#0对应的TRP)，则将TCI#0确定为第一CORESET对应的默认波束；若指定TRP为TRP#1(或CORESETPoolIndex#1对应的TRP)，则将TCI#1确定为第一CORESET对应的默认波束。
在本申请实施例中，MAC CE可以为指示第一CORESET的专用波束的MAC CE；或者，MAC CE也可以为指示包含第一CORESET在内的一个group(集合)的通用波束的MAC CE。
其中，group中除了可以包含第一CORESET之外，还可以包含其它CORESET、PDSCH、PUSCH(physical uplink shared channel，物理上行共享信道)、PUCCH(physical uplink control channel，物理上行控制信道)、CSI-RS(channel state information reference signal，信道状态信息参考信号)、SRS(sounding reference signal，探测参考信号)、PRS(Positioning Reference Signal，定位参考信号)、DMRS(Demodulation Reference Signal，解调参考信号)等中的至少一项。
需要说明的是，专用波束可以是指只用于第一CORESET的波束；通用波束可以是指可以用于至少一组信道和/或至少一种参考信号的波束，即除了可以用于第一CORESET之外，还可以用于与第一CORESET属于一个group的其它CORESET、PDSCH、PUSCH、参考信号等。
进一步的，在本申请实施例一种可能的实现方式中，网络设备还可以通过以下方式确定第一CORESET对应的默认波束：
方式一
确定最近一个需要检测PDCCH的时间单元中，索引取值最小的第二CORESET对应的第三波束；

进一步的，在本申请实施例一种可能的实现方式中，上述根据第三波束，确定默认波束，包括：

或者，

或者，
将第一指定值及第二指定值分别对应的至少一个第四波束，确定为默认波束。
方式三
确定最近一个需要检测PDCCH的时间单元中对应CORESETPoolIndex为第三指定值、且索引取值最小的第四CORESET对应的第五波束；
确定最近一个需要检测PDCCH的时间单元中对应控制资源集池索引为第四指定值、且索引取值最小的第五CORESET对应的第六波束；
将第五波束及第六波束，确定为默认波束。
在本申请的实施例中，网络设备确定第一CORESET对应的默认波束的具体方式，可以与前述实施例中用户设备确定第一CORESET对应的默认波束的具体方式相同，即步骤601可以分别采用本申请的各实施例中的任一种方式实现，本申请实施例并不对此作出限定，也不再赘述。

其中，配置信令，可以包括MAC CE和/或DCI。
在本申请实施例中，网络设备可以通过MAC CE与DCI中的至少一种，配置各个CORESET以及 各个CORESET对应的一个或多个波束。
作为一种可能的实现方式，网络设备通MAC CE配置至少一个CORESET及其对应的波束时，网络设备可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为至少一个CORESET激活的波束数量，并通过MAC CE激活相应数量的波束。
作为一种可能的实现方式，网络设备通DCI配置至少一个CORESET及其对应的波束时，网络设备还可以根据自身包含的TRP的数量以及当前的业务需求，确定可以为至少一个CORESET激活的波束数量，并通过向用户设备发送DCI为至少一个CORESET配置相应数量的波束。
需要说明的是，DCI中用于指示波束的TCI状态指示域在不同时刻可以显示为多个不同的codepoint(码点)，并且每个codepoint可以与一组波束对应，其中，每组波束可以包括一个或者两个波束。并且，codepoint与每组波束之间的对应关系可以由MAC CE来指示，从而网络设备通过DCI配置至少一个CORESET及其对应的一个或多个波束时，配置信令中可以同时包含MAC CE与DCI。
本申请实施例提供的默认波束的确定方法，通过基于指定的规则，确定第一CORESET对应的默认波束，其中，第一CORESET支持的TCI状态的最大数目大于或等于2。由此，通过预先定义指定的规则，确定支持多个TCI状态的CORESET对应的默认波束，从而提升了对应多个TCI状态的CORESET的默认波束确定的准确性，提升了多TRP数据传输的可靠性。
