控制信令携带有传输接入点TRP工作模式和/或波束映射方案的指示信息，TRP工作模式是基于单TRP的传输或基于多TRP的传输，所述波束映射方案包括面向多TRP对应的多个协作发送上行波束与时间单位之间的映射图样和/或所述时间单位的信息。
UE获取到该控制信令后，基于该控制信令携带的指示信息，确定基站调度指定的基于单TRP的传输或基于多TRP的传输。在基站调度指定TRP工作模式为基于多TRP的传输的情况下，还可以具体指定波束映射方案，包括面向多TRP对应的多个上行波束与时间单位之间的映射图样和时间单位中的至少一个，以便UE在基站调度下在基站的基于多TRP的传输和基于单TRP的传输的数据传输之间进行灵活切换。
可选地，基于多TRP的传输对应波束与时间单位之间的映射图样可以为下列中的一种，但不限于以下列举几种的可能：
1)周期映射，两个TCI(transmission configuration indication)对应的波束(采用波束方向的表示TCI state标注为TCI 1和TCI 2)依次循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2循环映射到4个时间单位，即映射顺序为TCI 1、TCI2、TCI1和TCI2；
2)连续映射，两个TCI对应的波束TCI 1和TCI 2连续循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2分别重复若干次每当一个TCI达到重复次数时切换为另一个TCI进行映射，例如在包含4个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2和TCI2，又例如在包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2、TCI2、TCI 1、TCI1、TCI2和TCI2；
3)对半映射(half-half)，两个TCI对应的波束TCI 1和TCI 2，分别映射到多个时间单位中的处于前半部分时间单位，以及后半部分时间单位，例如包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI1、TCI1、TCI 2、TCI2、TCI2和TCI2；
4)比特映射，通过比特图(Bitmap)指示具体的每一个TRP对应波束与时间单位之间的映射图样。
可选地，对于前述提及的时间单位，可选方案可以为下列中的一种，但不限于以下列举几种的可能：
1)名义传输时机(nominal repetition)；
2)实际传输时机(actual repetition)；
3)按时隙映射(slot-level)。
需要说明的是，前文在提及基于多TRP的传输时，通常以两个TRP进行举例，这是由于目前在基于多TRP的传输协作的相关技术中，限定为最多两个TRP，本实施例可以适用于基于更多TRP的传输的情况，对此并不限定。
步骤102，以该TRP工作模式和/或波束映射方案向基站发送数据。
可选地，UE在PUSCH上，以该TRP工作模式和/或波束映射方案向基站发送上行传输(PUSCHtransmission)。在本公开实施例中，上行传输可以为信令、数据、信令/数据混合传输。
可选地，UE在PUCCH上，以该TRP工作模式和/或波束映射方案向基站发送上行传输(PUCCHtransmission)。在本公开实施例中，上行传输可以为信令、数据、信令&数据混合传输。
UE以该基站调度指定的该TRP工作模式和/或波束映射方案向基站发送上行传输。由于UE采用的重传机制与TRP工作模式，以及波束映射方案之间存在一定的关联性，通过基站对TRP工作模式和/或波束映射方案的调度，实现了资源的优化配置，从而提高了上行信道的通信质量。
本实施例中，通过基站向UE发送控制信令之后，由于该控制信令携带有TRP工作模式和/或波束映射方案的指示信息，从而UE在基站调度下采用对应的TRP工作模式和/或波束映射方案在上行信道上发送上行传输，相应地，基站接收该UE以所述TRP工作模式和/或波束映射方案发送的上行传输，从而可以应用于PUSCH和PUCCH等信道，实现了在这些信道上进行单TRP的传输或基于多TRP的传输的切换，或者，波束映射方案的调度，提高了传输质量。
本实施例提供了另一种数据传输方法，图2为本发明实施例提供的另一种数据传输方法的流程示意图，由UE执行。本实施提供的方法，基站仅需要对UE的TRP工作模式进行调度，向UE通知基站调度所指定的TRP工作模式是单TRP的传输或者是基于多TRP的传输。
如图2所示，该方法可以包括以下步骤：
步骤201，接收基站发送的第一群组消息。
其中，第一群组消息携带有TRP工作模式的指示信息。TRP工作模式是基于单TRP的传输或者是基于多TRP的传输。
在本公开的一些实施例中，消息可以是PDCCH上传输的下行控制信令(DCI，Downlink Control Information)或是其他信令，或者，可以是PDSCH上传输的信令，本实施例中对于消息的具体形式不作限定。即：在本公开的一些实施例中，第一群组消息示例性的可以为第一群组DCI。
第一群组消息是由基站在基于参数，从基于单TRP的传输和基于多TRP的传输模式中确定一种适合UE的TRP工作模式之后，生成的携带有TRP工作模式的指示信息的群组消息。在一些实施例中，参数可以为以下的任意一种或多种：波束管理，对上行/下行信道状态进行信道质量测量得到的CSI测量量，调度TRP工作模式。
第一群组是基站发送至一组UE，其中包含执行本实施例的UE。UE根据预先接收到基站发送的配置信息或通信协议或条件参数或预存储的参数，从而获知该UE在第一群组消息中对应的信息比特位置，以及获知用于解扰的RNTI。在一些实施例中：所述第一群组消息为具有第一数量的比特位的比特位图(bitmap)，该第一群组消息的每一个比特位对应一个或多个UE，以指示该一个或多个UE所对应的用于解扰的RNTI。在一些实施例中，UE可以根 据高层基站发送的配置信息，确定该UE对应的比特位。在另一些实施例中，UE可以根据相应的通信协议，确定该UE对应的比特位。在又一些实施例中，UE可以根据条件参数，确定该UE对应的比特位；其中条件参数可以为以下的任一种：信道条件、负载条件，等。在又一些实施例中，UE可以根据预存储的参数，确定该UE对应的比特位；其中预存储的参数可以为以下的任意一种：UE等级(UEclass)、UE标识(UEID)，等。
UE在接收到第一群组消息之后，根据已获知的RNTI进行解扰，并读取自身对应的信息比特位置，以得到该UE对应的TRP工作模式。
步骤202，在上行信道以该TRP工作模式发送上行传输。
可选地，UE在PUSCH上，以该TRP工作模式向基站发送上行传输(PUSCHtransmission)。在本公开实施例中，上行传输可以为信令、数据、信令/数据混合传输。
可选地，UE在PUCCH上，以该TRP工作模式向基站发送上行传输(PUCCHtransmission)。在本公开实施例中，上行传输可以为信令、数据、信令&数据混合传输。
可选地，UE获取到第一群组消息携带的TRP工作模式之后，采用该TRP工作模式对应的解码策略，对基站向UE发送的对应于UE的特定消息进行解码，以确定基站对UE配置的数据调度信息，例如：基于码本传输的数据发送信息或者基于非码本传输的数据发送信息。根据基于码本传输的数据发送信息或者基于非码本传输的数据发送信息，UE采用基站调度指定的基于单TRP的传输或基于多TRP的传输工作模式在上行信道(例如PUSCH或PDSCH)发送数据。
在本公开的一些实施例中，该特定消息可以为特定的DCI。
在TRP工作模式为基于多TRP的传输的情况下，由于UE已预先由基站配置了波束映射方案，或者，UE已预定义了波束映射方案，从而UE可以执行该波束映射方案。
例如：基站可以根据基站向UE发送的信令，如RRC信令，对UE配置该波束映射方案。从而在TRP工作模式为基于多TRP的传输的情况下，UE根据配置的波束映射方案，在上行信道(例如PUSCH或PDSCH)以基于多TRP传输的工作模式发送数据。又例如：基站可以根据通信协议确定UE所对应的波束映射方案。还例如：基站可以根据条件参数确定UE所对应的波束映射方案；其中条件参数可以为以下的任意一种：信道条件、负载条件，等。再例如：基站可以根据预存储的参数确定UE所对应的波束映射方案；其中预存储的参数可以为以下的任意一种：UE等级(UEclass)、UE标识(UEID)，等。
可选地，波束映射方案包括基于多TRP的传输对应波束与时间单位之间的映射图样和/或时间单位。其中，基于多TRP的传输对应波束与时间单位之间的映射图样可以为下列中的一种，但不限于以下列举几种的可能：
1)周期映射，两个TCI(transmission configuration indication)对应的波束(采用波束方向的表示TCI state标注为TCI 1和TCI 2)依次循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2循环映射到4个时间单位，即映射顺序为TCI 1、TCI2、TCI1和TCI2；
2)连续映射，两个TCI对应的波束TCI 1和TCI 2连续循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2分别重复若干次每当一个TCI达到重复次数时切换为另一个TCI进行映射，例如在包含4个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2和TCI2，又例如在包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2、TCI2、TCI 1、TCI1、TCI2和TCI2；
3)对半映射(half-half)，两个TCI对应的波束TCI 1和TCI 2，分别映射到多个时间单位中的处于前半部分时间单位，以及后半部分时间单位，例如包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI1、TCI1、TCI 2、TCI2、TCI2和TCI2；

对于前述提及的时间单位，可选方案可以为下列中的一种，但不限于以下列举几种的可能：
1)名义传输时机(nominal repetition)；
2)实际传输时机(actual repetition)；
3)按时隙映射(slot-level)。
需要说明的是，前文在提及基于多TRP的传输时，通常以两个TRP进行举例，这是由于目前在基于多TRP的传输协作的相关技术中，限定为最多两个TRP，本实施例可以适用于基于更多TRP的传输的情况，对此并不限定。
本实施例中，通过基站在PDCCH上向UE发送DCI之后，由于该DCI携带有TRP工作模式和/或波束映射方案的指示信息，从而UE在基站调度下采用对应的TRP工作模式和/或波束映射方案在PUSCH上发送数据，相应地，基站接收该UE在PUSCH上以所述TRP工作模式和/或波束映射方案发送的数据，从而实现了在PUSCH上进行单TRP的传输或基于多TRP的传输的切换，或者，波束映射方案的调度，提高了PUSCH的数据传输质量。
图3为本发明实施例提供的另一种数据传输方法的流程示意图，由UE执行。本实施提供的方法，基站对UE的TRP工作模式和波束映射方案进行调度，UE获知基站调度所指定的TRP工作模式是单TRP的传输或者是基于多TRP的传输，以及波束映射方案，并据此在上行 信道上进行数据发送。
如图3所示，该方法可以包括以下步骤。
步骤301，接收基站发送的第一群组消息。
其中，第一群组消息携带有TRP工作模式的指示信息。TRP工作模式是基于单TRP的传输或者是基于多TRP的传输。
在本公开的一些实施例中，消息可以是PDCCH上传输的下行控制信令(DCI，Downlink Control Information)或是其他信令，或者，可以是PDSCH上传输的信令，本实施例中对于消息的具体形式不作限定。即：在本公开的一些实施例中，第一群组消息示例性的可以为第一群组DCI。第一群组消息是由基站在基于参数，从基于单TRP的传输和基于多TRP的传输模式中确定一种适合UE的TRP工作模式之后，生成的携带有TRP工作模式的指示信息的群组消息。在一些实施例中，该参数可以包括以下任一种：波束管理，或者是对上行/下行信道状态进行信道质量测量得到的CSI测量量，调度TRP工作模式，等。
第一群组消息由基站发送至一组UE，其中包含执行本实施例的UE。UE预先接收到基站通过高层信令发送的配置信息，从而已获知该UE在第一群组DCI中对应的信息比特位置，以及获知用于解扰的RNTI。UE在接收到第一群组DCI之后，根据已获知的RNTI进行解扰，并读取自身对应的信息比特位置，以得到该UE对应的TRP工作模式。
步骤302，接收所述基站发送的针对UE的第一特定消息。
第一特定消息是针对UE发送的，用于对UE进行动态配置，其中，第一特定消息中携带有数据调度信息，数据调度信息包括基于码本传输的数据发送信息或基于非码本传输的数据发送信息，在TRP工作模式为基于多TRP的传输的情况下，第一特定消息还包括波束映射方案的指示信息。
在本公开的一些实施例中，该第一特定消息可以为DCI，即第一特定DCI。
可选地，波束映射方案包括映射图样和时间单位。基于多TRP的传输对应波束与时间单位之间的映射图样可以为下列中的一种，但不限于以下列举几种的可能：
1)周期映射，两个TCI对应的波束(采用波束方向的表示TCI state标注为TCI 1和TCI 2)依次循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2循环映射到4个时间单位，即映射顺序为TCI 1、TCI2、TCI1和TCI2；
2)连续映射，两个TCI对应的波束TCI 1和TCI 2连续循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2分别重复若干次每当一个TCI达到重复次数时切换为另一个TCI进行映射，例如在包含4个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2和TCI2，又例如在包含8个时间单位的情况下，映射顺序为TCI 1、 TCI1、TCI2、TCI2、TCI 1、TCI1、TCI2和TCI2；
3)对半映射(half-half)，两个TCI对应的波束TCI 1和TCI 2，分别映射到多个时间单位中的处于前半部分时间单位，以及后半部分时间单位，例如包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI1、TCI1、TCI 2、TCI2、TCI2和TCI2；
4)比特映射，通过比特图(Bitmap)指示具体的每一个TRP对应波束与时间单位之间的映射图样。
可选地，对于前述提及的时间单位，可选方案可以为下列中的一种，但不限于以下列举几种的可能：
1)名义传输时机(nominal repetition)；
2)实际传输时机(actual repetition)；
3)按时隙映射(slot-level)。
需要说明的是，前文在提及基于多TRP的传输时，通常以两个TRP进行举例，这是由于目前在基于多TRP的传输协作的相关技术中，限定为最多两个TRP，本实施例可以适用于基于更多TRP的传输的情况，对此并不限定。
步骤303，根据第一群组消息中TRP工作模式对应的解码策略，对第一特定消息进行解码。
在确定出UE对应的TRP工作模式之后，UE即可获知基站通过下行信道(例如PDCCH或PDSCH)下发的第一特定消息(例如第一特定DCI)中所需读取的特定信息域所在的比特位置，这是由于，UE已预先配置了不同TRP工作模式下针对UE的第一特定消息的解码策略，该解码策略指示了UE所需读取的特定信息域所在的比特位置，UE基于该解码策略进行解码，读取对应的比特位置。
若该UE的TRP工作模式为基于多TRP的传输，则对第一特定消息解码得到波束映射方案的指示信息，以及数据调度信息，例如基于码本传输的数据发送信息或者基于非码本传输的数据发送信息等。若该UE的TRP工作模式为基于单TRP的传输，则对第一特定消息解码得到数据调度信息。
可选地，波束映射方案的指示信息，可以是占用若干个比特的标识符，对应波束映射方案中的映射图样，或者对应时间单位，或者对应映射图样和时间单位的组合。具体基于标识符确定具体映射方案的方式至少存在以下几种可能的实现方式：
作为第一种可能的实现方式，基站预先发送了映射图样和时间单位中的一个，从而UE已预先配置了映射图样或时间单位。基站还通过发送或者对该UE预定义了标识符与映射图样和时间单位中的另一个之间的对应关系，从而UE可以根据第一特定消息中的标识符，确 定对应的映射图样或时间单位。
例如：基站通过RRC信令配置映射图样，通过该RRC信令或者其他高层信令配置了标识符与时间单位之间的对应关系。在接收到第一特定消息(例如第一特定DCI)之后，UE通过第一特定消息中的标识符，确定对应的时间单位。具体标识符与时间单位之间的对应关系如下表所示1。
标识符 时间单位

表1标识符与时间单位之间的对应关系之一
可以理解的是，表1中的每一个元素、每一条对应关系，都是独立存在的；这些元素、对应关系被示例性的列在同一张表格中，但是并不代表表格中的所有元素、对应关系必须根据表格1中所示的同时存在。其中每一个元素的值和每一对应关系，是不依赖于表1中任何其他元素值或对应关系。因此本领域内技术人员可以理解，该表1中的每一个元素的取值、每一条对应关系，各种都是一个独立的实施例。
又例如：基站通过RRC信令配置时间单位，通过该RRC信令或者其他高层信令配置了标识符与映射图样之间的对应关系。在接收到第一特定DIC之后，UE通过第一特定DCI中的标识符，确定对应的映射图样。
作为第二种可能的实现方式，基站预先通过高层信令，如RRC信令，发送了标识符与波束映射方案之间的对应关系，或者是UE预定义了标识符与波束映射方案之间的对应关系。该波束映射方案是映射图样和时间单位的组合，从而UE可以根据第一特定DCI中的标识符，确定对应的映射图样和时间的组合。
标识符 映射图样和时间的组合
0 交替映射到名义传输时机

作为第三种可能的实现方式，基站预先发送了波束映射方案，或者对UE预定义了波束映射方案，包括基于多TRP的传输对应波束与时间单位之间的一种可能的映射图样和/或一种可能的时间单位。基于第一特定DCI中携带的标识符，确定是否采用该映射图样和/或时间单位。在一些实施例中，基站可以通过高层信令发送该波束映射方案。
步骤304，根据解码后的第一特定消息，在上行信道以该TRP工作模式发送上行传输。
在本公开的一些实施例中，该特定消息可以为特定的DCI。
在一些实施例中，该上行信道为PUSCH或PUCCH；优选的可以为PUSCH。
响应于TRP工作模式为基于单TRP的传输，根据解码后的第一特定DCI可得到数据调度信息，根据该数据调度信息，在PUSCH以该基于单TRP的传输发送数据；
或
响应于TRP工作模式为基于多TRP的传输，根据解码后的第一特定DCI可得到数据调度信息，以及确定波束映射方案，根据波束映射方案、数据调度信息，在PUSCH以该基于多TRP的传输发送数据。
可选地，UE在PUSCH上向基站发送上行传输(PUSCHtransmission)。在本公开实施例中，上行传输可以为信令、数据、信令/数据混合传输。
可选地，UE在PUCCH上发送上行传输(PUCCHtransmission)。在本公开实施例中，上行传输可以为信令、数据、信令&数据混合传输。
本实施例中，通过基站在PDCCH上向UE发送DCI之后，由于该DCI携带有TRP工作模式和/或波束映射方案的指示信息，从而UE在基站调度下采用对应的TRP工作模式和/或波束映射方案在PUSCH上发送数据，相应地，基站接收该UE在PUSCH上以所述TRP工作模式和/或波束映射方案发送的数据，从而实现了在PUSCH上进行单TRP的传输或基于多TRP的 传输的切换，或者，波束映射方案的调度，提高了PUSCH的数据传输质量。
图4为本发明实施例提供的另一种数据传输方法的流程示意图，由UE执行。本实施提供的方法，基站对UE的TRP工作模式和波束映射方案进行调度，UE通过间接方式获知基站调度所指定的TRP工作模式是单TRP的传输或者是基于多TRP的传输，通过直接方式获知波束映射方案，并据此在上行信道上进行数据发送。
如图4所示，该方法可以包括以下步骤。

第二群组消息由基站发送至一组UE，其中包含执行本实施例的UE。UE预先接收到基站发送的配置信息，从而已获知该UE在第二群组DCI中对应的信息比特位置，以及获知用于解扰的RNTI。UE在接收到第二群组DCI之后，根据已获知的RNTI进行解扰，并读取自身对应的信息比特位置，以得到该UE对应的波束映射方案。
在一些实施例中，UE根据预先接收到基站发送的配置信息或通信协议或条件参数或预存储的参数，从而获知该UE在第一群组消息中对应的信息比特位置，以及获知用于解扰的RNTI。在一些实施例中：所述第一群组消息为具有第一数量的比特位的比特位图(bitmap)，该第一群组消息的每一个比特位对应一个或多个UE，以指示该一个或多个UE所对应的用于解扰的RNTI。在一些实施例中，UE可以根据高层基站发送的配置信息，确定该UE对应的比特位。在另一些实施例中，UE可以根据相应的通信协议，确定该UE对应的比特位。在又一些实施例中，UE可以根据条件参数，确定该UE对应的比特位；其中条件参数可以为以下的任一种：信道条件、负载条件，等。在又一些实施例中，UE可以根据预存储的参数，确定该UE对应的比特位；其中预存储的参数可以为以下的任意一种：UE等级(UEclass)、UE标识(UEID)，等。

2)实际传输时机(actual repetition)；
3)按时隙映射(slot-level)。
需要说明的是，前文在提及基于多TRP的传输时，通常以两个TRP进行举例，这是由于目前在基于多TRP的传输协作的相关技术中，限定为最多两个TRP，本实施例可以适用于基于更多TRP的传输的情况，对此并不限定。
步骤402，根据第二群组消息携带的所述波束映射方案的指示信息，确定对应的TRP工作模式。
可选地，波束映射方案的指示信息，可以是占用若干个比特的标识符，该标识符与波束映射方案以及TRP之间存在三者的对应关系。基于该标识符，可以对应波束映射方案中的映射图样和TRP工作模式，或者对应时间单位和TRP工作模式，或者对应映射图样和时间单位的组合以及TRP工作模式。
基于标识符确定对应映射方案和TRP工作模式的方式至少存在以下几种可能的实现方式：
作为第一种可能的实现方式，基站预先通过高层信令，如RRC信令，对UE已预先配置 了映射图样和时间单位中的一个，还可以是对UE预定义了映射图样和时间单位中的一个。在进行调度时，基站通过该高层信令发送了标识符与映射图样和时间单位中的另一个之间的对应关系，从而UE可以根据第二群组DCI中的标识符，确定对应的映射图样或时间单位。
例如：基站通过RRC信令配置映射图样，通过该RRC信令或者其他高层信令配置了标识符与时间单位和TRP工作模式之间的对应关系。在接收到第二群组DCI之后，UE通过第二群组DCI中的标识符，确定对应的时间单位和TRP工作模式。具体标识符与时间单位和TRP工作模式之间的对应关系如下表所示3。

又例如：基站通过RRC信令配置时间单位，通过该RRC信令或者其他高层信令配置了标识符与映射图样和TRP工作模式之间的对应关系。在接收到第二群组DCI之后，UE通过第二群组DCI中的标识符，确定对应的映射图样和TRP工作模式。

作为第三种可能的实现方式，基站预先通过高层信令发送了波束映射方案，或者对UE预定义了波束映射方案，包括基于多TRP的传输对应波束与时间单位之间的一种可能的映射图样和/或一种可能的时间单位。基于第二群组DCI中携带的标识符，确定是否采用该映射图样和/或时间单位。
步骤403，根据TRP工作模式，对基站发送的针对UE的特定DCI进行解码。
UE已预先配置了不同TRP工作模式下解码策略，该解码策略指示了UE所需读取的特定信息域所在的比特位置，UE基于该解码策略进行解码，读取特定DCI对应的比特位置，以得到数据调度信息，例如基于码本传输的数据发送信息或者基于非码本传输的数据发送信息。
例如：SRI或者TPMI/RI指示域在UE面向基于多TRP的传输时，基于单TRP的传输的2bit指示域直接扩展为两个TRP波束发送时的4bit。
步骤404，根据解码后的特定消息，在PUSCH以所述TRP工作模式和波束映射方案发送数据。
在本公开的一些实施例中，该特定消息可以为特定的DCI。
响应于TRP工作模式为基于单TRP的传输，根据解码后的特定DCI可得到数据调度信息，根据该数据调度信息，在上行信道(例如PUSCH或PUCCH)以该基于单TRP的传输发送数据；
或
响应于TRP工作模式为基于多TRP的传输，则根据解码后的特定消息可得到数据调度信息，根据前述步骤中确定出的波束映射方案，以及根据该数据调度信息，在上行信道(例如 PUSCH或PUCCH)以该基于多TRP的传输发送数据。
在一些实施例中，优选的，该上行信道为PUCCH。
本实施例中，通过基站在PDCCH上向UE发送DCI之后，由于该DCI携带有TRP工作模式和/或波束映射方案的指示信息，从而UE在基站调度下采用对应的TRP工作模式和/或波束映射方案在PUSCH上发送数据，相应地，基站接收该UE在PUSCH上以所述TRP工作模式和/或波束映射方案发送的数据，从而实现了在PUSCH上进行单TRP的传输或基于多TRP的传输的切换，或者，波束映射方案的调度，提高了PUSCH的数据传输质量。
图5为本发明实施例提供的另一种数据传输方法的流程示意图，由UE执行。本实施提供的方法，基站对UE的TRP工作模式和波束映射方案进行调度，UE获知基站调度所指定的TRP工作模式是单TRP的传输或者是基于多TRP的传输，以及波束映射方案，并据此在上行信道上进行数据发送。
如图5所示，该方法可以包括以下步骤。
步骤501，接收基站在PDCCH上发送的针对所述UE的第二特定消息。
其中，第二特定消息携带有波束映射方案的指示信息和/或TRP工作模式的指示信息。
第二特定消息是由基站在基于波束管理，或者是对上行/下行信道状态进行信道质量测量得到的CSI测量量，调度波束映射方案，以从候选的多种波束映射方案中，确定一种适合UE的波束映射方案和/或TRP工作模式之后，生成的携带有该UE的波束映射方案的指示信息和/或TRP工作模式的指示信息的针对该UE的特定消息。

1)周期映射，两个TCI对应的波束(采用波束方向的表示TCI state标注为TCI 1和TCI 2)依次循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2循环映射到4个时间单位，即映射顺序为TCI 1、TCI2、TCI1和TCI2；
2)连续映射，两个TCI对应的波束TCI 1和TCI 2连续循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2分别重复若干次每当一个TCI达到重复次数时切换为另一个TCI进行映射，例如在包含4个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2和TCI2，又例如在包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2、TCI2、TCI 1、TCI1、TCI2和TCI2；
3)对半映射(half-half)，两个TCI对应的波束TCI 1和TCI 2，分别映射到多个时 间单位中的处于前半部分时间单位，以及后半部分时间单位，例如包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI1、TCI1、TCI 2、TCI2、TCI2和TCI2；

可选地，对于前述提及的时间单位，可选方案可以为下列中的一种，但不限于以下列举几种的可能：
1)名义传输时机(nominal repetition)；
2)实际传输时机(actual repetition)；
3)按时隙映射(slot-level)。
需要说明的是，前文在提及基于多TRP的传输时，通常以两个TRP进行举例，这是由于目前在基于多TRP的传输协作的相关技术中，限定为最多两个TRP，本实施例可以适用于基于更多TRP的传输的情况，对此并不限定。
进一步地，UE在接收到第二特定消息之后，可以采用预定义，或者预配置的几种候选解码策略，对其进行尝试性解码，直至解码成功，以得到第二特定消息携带的波束映射方案的指示信息和/或TRP工作模式的指示信息。
可选地，波束映射方案的指示信息，可以是占用若干个比特的标识符，对应波束映射方案中的映射图样，或者对应时间单位，或者对应映射图样和时间单位的组合。具体基于标识符确定具体映射方案的方式至少存在以下几种可能的实现方式：
作为第一种可能的实现方式，基站预先通过高层信令，如RRC信令，发送了映射图样和时间单位中的一个，从而UE已预先配置了映射图样或时间单位。基站还通过该高层信令发送或者对该UE预定义标识符与映射图样和时间单位中的另一个之间的对应关系，从而UE可以根据第二特定DCI中的标识符，确定对应的映射图样或时间单位。
例如：基站通过RRC信令配置映射图样，通过该RRC信令或者其他高层信令配置了标识符与时间单位之间的对应关系。在接收到第二特定DCI之后，UE通过第二特定DCI中的标识符，确定对应的时间单位。具体标识符与时间单位之间的对应关系如表5所示。

表5标识符与时间单位之间的对应关系之二
可以理解的是，表5中的每一个元素、每一条对应关系，都是独立存在的；这些元素、对应关系被示例性的列在同一张表格中，但是并不代表表格中的所有元素、对应关系必须根据表格5中所示的同时存在。其中每一个元素的值和每一对应关系，是不依赖于表5中任何其他元素值或对应关系。因此本领域内技术人员可以理解，该表5中的每一个元素的取值、每一条对应关系，各种都是一个独立的实施例。
需要说明的是，表5中无(none)对应在面向单TRP的传输方式下，表示基站未选定时间单位。
又例如：基站通过RRC信令配置时间单位，通过该RRC信令或者其他高层信令配置了标识符与映射图样之间的对应关系。在接收到第二特定DCI之后，UE通过第二特定DCI中的标识符，确定对应的映射图样。
作为第二种可能的实现方式，基站预先通过高层信令，如RRC信令，发送了标识符与波束映射方案之间的对应关系，或者是UE预定义了标识符与波束映射方案之间的对应关系。该波束映射方案是映射图样和时间单位的组合，从而UE可以根据第二特定DCI中的标识符，确定对应的映射图样和时间的组合。表6为标识符与波束映射方案之间的对应关系。

需要说明的是，表6中无(none)对应在面向单TRP的传输方式下，表示基站未选定波 束映射方案，即未选定映射图样和时间的组合。
作为第三种可能的实现方式，基站预先通过高层信令发送了波束映射方案，或者对UE预定义了波束映射方案，包括基于多TRP的传输对应波束与时间单位之间的一种可能的映射图样和/或一种可能的时间单位。基于第二特定DCI中携带的标识符，确定是否采用该映射图样和/或时间单位。
步骤502，在上行信道上以该TRP工作模式和/或波束映射方案发送数据。
在一些实施例中，该上行信道可以为PUSCH或PUCCH；优选的，可以为PUSCH。
可选地，在第二特定消息中，还可以携带有数据调度信息，该数据调度信息包括：基于码本传输的数据发送信息或基于非码本传输的数据发送信息。
响应于TRP工作模式为基于单TRP的传输，根据该数据调度信息，在PUSCH以该基于单TRP的传输发送数据；
或
响应于TRP工作模式为基于多TRP的传输，根据前述步骤中确定出的波束映射方案，以及根据该数据调度信息，在PUSCH以该基于多TRP的传输发送数据。

1)周期映射，两个TCI对应的波束(采用波束方向的表示TCI state标注为TCI 1和TCI 2)依次循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2循环映射到4个时间单位，即映射顺序为TCI 1、TCI2、TCI1和TCI2；
2)连续映射，两个TCI对应的波束TCI 1和TCI 2连续循环映射到配置的多个时间单位上，例如在包含4个时间单位的情况下，TCI 1和TCI2分别重复若干次每当一个TCI达到重复次数时切换为另一个TCI进行映射，例如在包含4个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2和TCI2，又例如在包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI2、TCI2、TCI 1、TCI1、TCI2和TCI2；
3)对半映射(half-half)，两个TCI对应的波束TCI 1和TCI 2，分别映射到多个时间单位中的处于前半部分时间单位，以及后半部分时间单位，例如包含8个时间单位的情况下，映射顺序为TCI 1、TCI1、TCI1、TCI1、TCI 2、TCI2、TCI2和TCI2；
4)比特映射，通过比特图(Bitmap)指示具体的每一个TRP对应波束与时间单位之间的映射图样。
可选地，对于前述提及的时间单位，可选方案可以为下列中的一种，但不限于以下列举几种的可能：
1)名义传输时机(nominal repetition)；
2)实际传输时机(actual repetition)；
3)按时隙映射(slot-level)。
需要说明的是，前文在提及基于多TRP的传输时，通常以两个TRP进行举例，这是由于目前在基于多TRP的传输协作的相关技术中，限定为最多两个TRP，本实施例可以适用于基于更多TRP的传输的情况，对此并不限定。
可选地，波束映射方案的指示信息，可以是占用若干个比特的标识符，对应波束映射方案中的映射图样，或者对应时间单位，或者对应映射图样和时间单位的组合。具体基站至少存在以下几种可能的实现方式对UE进行映射方案的配置：
作为第一种可能的实现方式，基站预先通过高层信令，如RRC信令，发送了映射图样和时间单位中的一个，从而UE已预先配置了映射图样或时间单位。基站还通过该高层信令发 送或者对该UE预定义标识符与映射图样和时间单位中的另一个之间的对应关系，从而UE可以根据第二特定DCI中的标识符，确定对应的映射图样或时间单位。
例如：基站通过RRC信令配置映射图样，通过该RRC信令或者其他高层信令配置了标识符与时间单位之间的对应关系。在接收到第二特定DCI之后，UE通过第二特定DCI中的标识符，确定对应的时间单位。
需要说明的是，标识符中可以存在特定取值对应在面向单TRP的传输方式下，表示基站未选定时间单位。
又例如：基站通过RRC信令配置时间单位，通过该RRC信令或者其他高层信令配置了标识符与映射图样之间的对应关系。在接收到第二特定DCI之后，UE通过第二特定DCI中的标识符，确定对应的映射图样。
作为第二种可能的实现方式，基站预先通过高层信令，如RRC信令，发送了标识符与波束映射方案之间的对应关系，或者是UE预定义了标识符与波束映射方案之间的对应关系。该波束映射方案是映射图样和时间单位的组合，从而UE可以根据第二特定DCI中的标识符，确定对应的映射图样和时间的组合。
需要说明的是，标识符中可以存在特定取值对应在面向单TRP的传输方式下，表示基站未选定波束映射方案，即未选定映射图样和时间的组合。
作为第三种可能的实现方式，基站预先通过高层信令发送了波束映射方案，或者对UE预定义了波束映射方案，包括基于多TRP的传输对应波束与时间单位之间的一种可能的映射图样和/或一种可能的时间单位。基于第二特定DCI中携带的标识符，确定是否采用该映射图样和/或时间单位。

本实施例中，通过基站在PDCCH上向UE发送DCI之后，由于该DCI携带有TRP工作模式和/或波束映射方案的指示信息，从而UE在基站调度下采用对应的TRP工作模式和/或波束映射方案在PUSCH上发送数据，相应地，基站接收该UE在PUSCH上以所述TRP工作模式和/或波束映射方案发送的数据，从而实现了在PUSCH上进行单TRP的传输或基于多TRP的传输的切换，或者，波束映射方案的调度，提高了PUSCH的数据传输质量。
