Description

调制与编码策略MCS的配置方法、装置及通信设备 技术领域
本申请涉及无线通信技术领域，尤其涉及一种MCS(Modulation and Coding Scheme，调制与编码策略)的配置方法、装置及通信设备。
背景技术
视频监控、智能家居、可穿戴设备和工业传感监测等物联网业务，对网络速率和时延的要求相对较高，因此基于这种情况，很多公司提出了在5G新空口中再设计一种新的UE(User Equipment，用户终端)用以覆盖这种中端物联网设备的要求，这种新的终端类型叫做Redcap(Reduced capability，能力受限)终端。对于Redcap终端来说，由于终端能力的降低，比如接收天线的减少，会带来覆盖损失，因此需要进行覆盖增强。
相关技术中，对于需要进行覆盖增强的终端来说，有两个可用的MCS表格。其中一个示例性的可以用于覆盖终端能力较好的情况或其他恰当的情况，另一个示例性的可以用于覆盖终端能力较差或者传输要求较高(比如对误码率要求较高)的情况或其他恰当的情况。在随机接入过程中，各传输信道都有不同程度的覆盖损失，因此在随机接入过程中也可以通过配置各信道传输时使用的MCS表格，以增强覆盖。但是，终端使用哪一个MCS表格是由RRC(Radio Resource Control，无线资源控制层)配置的，而在随机接入过程中,RRC连接并没有建立，因此无法在随机接入过程中对MCS表格进行配置。

需要说明的是，由于在终端的随机接入过程中，终端与基站之间进行数据传输的各信道也会出现覆盖损失，因此也可以通过在随机接入过程中配置各信道所使用的MCS表格的方式，来进行覆盖增强，以提升随机接入过程中的数据传输质量。但是，MCS表格的配置是由RRC完成的，而在终端的随机接入过程中RRC连接还没有建立，从而无法通过RRC实现随机接入过程中的MCS表格的配置。因此，在本申请实施例中，可以在终端的随机接入过程中，重新设置MCS表格的配置策略，以实现随机接入过程中各信道使用的MSC表格。
在本申请的所有实施例中，对于需要进行覆盖增强的终端来说，有两个可用的MCS表格。其中一个示例性的可以用于覆盖终端能力较好的情况或其他恰当的情况，另一个示例性的可以用于覆盖终端能力较差或者传输要求较高(比如对误码率要求较高)的情况或其他恰当的情况。在本申请的所有实施例中，在本公开的所有实施例中，至少1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。比如，两种MCS表格可以是如表1所示的第一MCS表格和表2所示的第二MCS表格。
表1
Figure PCTCN2020129861-appb-000001
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。
表2
Figure PCTCN2020129861-appb-000002
可以理解的是，表2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2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2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2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。
作为一种可能的实现方式，由于两种MCS表格的适用场景和终端能力相关，因此在终端的随机接入过程中，可以根据终端能力选择与终端能力相适应的MCS表格，并根据当前终端与基站的通信进程，在相应的信道中使用确定的MCS表格。
作为另一种可能的实现方式，还可以通过基站设置各信道使用的MCS表格，因此，终端可以获取基站发送的指示消息，并对指示消息进行解析处理，以确定在随机接入过程中使用的MCS表格。
作为再一种可能的实现方式，还可以预先配置确定MCS表格的规则，从而在终端的随机接入过程中，可以根据预先配置的规则，确定各信道使用的MCS表格。比如，预先配置的规则可以是随机接入过程中各信道与MCS表格的映射关系，本申请实施例对此不做限定。
本申请实施例提供的MCS的配置方法，通过基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格；其中，指定的策略包括以下策略中的任意一种：终端的能力、指示消息及预先配置的规则。由此，通过预先设置用于在终端的随机接入过程中配置MCS表格的指定策略，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强。
在本申请一种可能的实现形式中，可以在终端的随机接入过程中使用与终端能力相配的MCS表格，以提升随机接入过程中数据传输的可靠性。
下面结合图2，对本申请实施例提供的另一种MCS的配置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MCS的配置方法的流程示意图，应用于终端。
如图2所示，该MCS的配置方法，包括以下步骤：
步骤201，响应于终端为第一能力终端，确定终端在随机接入过程中全部或部分信道使用第一MCS表格。
作为一种可能的实现方式，由于两种MCS表格的适用场景和终端能力相关，因此指定的策略可以是终端能力，从而在终端的随机接入过程中，可以根据终端能力确定与终端能力相适应的MCS表格，并根据当前终端与基站的通信进程，在相应的信道中使用确定的MCS表格。
其中，第一能力终端，可以是用户能力较低的终端；相对来说，第一能力终端的用户能力可以比第二能力终端的用户能力低。用户能力可以包括接收天线的个数与接收带宽中的任意一项。比如，第一能力终端可以是应用在5G新空口模式中的Redcap终端，第二能力终端可以是应用在LTE(Long Term Evolution，长期演进)或5G或任何一代通讯系统中的普通终端，本申请实施例对此不做限定。
在本申请实施例中，由于第一能力终端的用户能力不足，因此响应于终端为第一能力终端，可以在随机接入过程中使用频谱效率较低的第一MCS表格，比如，可以是如表1所示的第一MCS表格。
在本申请的实施例中，步骤201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202，响应于终端为第二能力终端，确定终端在随机接入过程中全部或部分信道使用第二MCS表格，其中，至少不少于1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。
在本申请实施例中，由于第二能力终端的用户能力较好，因此响应于终端为第二能力终端，可以在随机接入过程中使用频谱效率较高的第二MCS表格。比如，可以是如表2所示的第二MCS表格。
需要说明的是，在本申请实施例中，可以同时限定第一能力终端在随机接入过程中全部或部分信道使用第一MCS表格，以及第二能力终端在随机接入过程中全部或部分信道使用第二MCS表格。
或者，也可以仅限定第一能力终端在随机接入过程中全部或部分信道使用第一MCS表格，而对第二能力终端使用的MCS表格不做限定，比如，响应于终端为第二能力终端，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
或者，也可以仅限定第二能力终端在随机接入过程中全部或部分信道使用第二MCS表格，而对第一能力终端使用的MCS表格不做限定；比如，响应于终端为第一能力终端，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
进一步的，终端可以首先将自身的用户能力发送至基站，以使基站根据终端的能力确定随机接入过程中各信道使用的MCS表格。即在本申请实施例一种可能的实现形式中，上述步骤201之前，还可以包括：
根据终端的能力，确定向基站发送的第一随机接入消息中PRACH(Physical Random Access Channel，物理随机接入信道)资源的标识，
或者，
根据终端的能力，确定向基站发送的第三随机接入消息中的上行调度准许UL grant中的指示信息。
作为一种可能的实现方式，由于终端在随机接入过程中，会向基站发送第一随机接入消息，因此终端可以在向基站发送第一随机接入消息时，根据终端的能力确定第一随机接入消息中的PRACH资源的标识，以通过第一随机接入消息中的PRACH资源的标识指示终端为第一能力终端还是第二能力终端。从而，基站在获取到第一随机接入消息之后，可以根据第一接入消息中的PRACH资源的标识确定终端的能力，并响应于确定终端为第一能力终端，确定在随机接入过程中传输第二随机接入消息或第三随机接入消息或第四随机接入消息时，使用第一MCS表格；响应于终端为第二能力终端，确定在随机接入过程中传输第二随机接入消息或第三随机接入消息或第四随机接入消息时，使用第二MCS表格。
作为另一种可能的实现方式，由于终端在随机接入过程中，会向基站发送第三随机接入消息，因此终端可以在向基站发送第三随机接入消息时，根据终端的能力确定第三随机接入消息中的UL grant中的指示信息，以通过第三随机接入消息中的UL grant中的指示信息，指示终端为第一能力终端还是第二能力终端。从而，基站在获取到第三随机接入消息之后，可以根据第三随机接入消息中的UL grant中的指示信息确定终端的能力，并响应于终端为第一能力终端，确定在随机接入过程中传输第二随机接入消息或第三随机接入消息或第四随机接入消息时，使用第一MCS表格；响应于终端为第二能力终端，确定在随机接入过程中传输第二随机接入消息或第三随机接入消息、第四随机接入消息时，使用第二MCS表格。
本申请实施例提供的MCS的配置方法，通过响应于终端为第一能力终端，确定终端在随机接入过程中全部或部分信道使用第一MCS表格，或者，响应于终端为第二能力终端，确定终端在随机接入过程中全部或部分信道使用第二MCS表格。在本公开的所有实施例中，至少1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。由此，通过根据终端的能力在随机接入过程中配置与终端能力相匹配的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
在本申请一种可能的实现形式中，基站还可以通过广播的形式通知终端在随机接入过程中各信道使用的MCS表格。
下面结合图3，对本申请实施例提供的再一种MCS的配置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MCS的配置方法的流程示意图，应用于终端。
如图3所示，该MCS的配置方法，包括以下步骤：
步骤301，响应于监听到广播指示消息，根据广播指示消息的指示确定终端在随机接入过程中全部或部分信道使用的MCS表格。
作为另一种可能的实现方式，可以通过基站设置各信道使用的MCS表格，因此，终端可以获取基站发送的指示消息，并对指示消息进行解析处理，以确定在随机接入过程中使用的MCS表格。可选地，基站可以通过广播的方式通知终端在随机接入过程中全部信道或部分信道使用的MCS表格，即指示消息可以为广播指示消息。
作为一种示例，基站可以在需要通知终端在随机接入过程中全部信道或部分信道使用的MCS表格时，通过广播信道向终端发送广播指示消息。因此，终端响应于监听到基站发送的广播指示消息，可以根据广播指示消息的指示确定终端在随机接入过程中全部或部分信道使用的MCS表格；响应于未监听到基站发送的广播指示消息，可以根据设置默认使用第一MCS表格或者第二MCS表格。
可选的，广播指示消息中可以用于指示各种能力终端与MCS表格的对应关系；相应的，上述步骤301，可以包括：
应于监听到广播指示消息，确定终端的能力；
根据广播指示消息指示的各种能力终端与MCS表格的对应关系、及终端的能力，确定终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，基站可以根据自身的策略确定各种能力终端在随机接入过程中使用的MCS表格，并在广播指示消息中携带各种能力终端与MCS表格的对应关系并发送至终端。因此，终端响应于监听到基站发送的广播指示消息，可以从广播指示消息中获取各种能力终端与MCS表格的对应关系， 并根据自身的终端能力，从各种能力终端与MCS表格的对应关系中获取与终端能力对应的MCS表格，并在随机接入过程中的全部或部分信道中使用确定的MCS表格。具体的，若终端在确定出MCS表格之后，第一随机接入消息、第二随机接入消息、第三随机接入消息及第四随机接入消息均未传输，则可以在随机接入过程中的全部信道中使用确定的MCS表格；若终端在确定出MCS表格之后，已经传输了部分随机接入消息，则可以在传输剩余随机接入消息的部分信道中使用确定的MCS表格。
举例来说，广播指示消息中包括的各种能力终端与MCS表格的对应关系为：第一能力终端与第一MCS表格对应、第二能力终端与第二MCS表格对应，且终端为第一能力终端，则终端可以在随机接入过程中的全部或部分信道中使用第一MCS表格。
可选的，广播指示消息中还可以用于指示各个信道与MCS表格的对应关系；相应的，上述步骤301，可以包括：
响应于监听到广播消息，根据广播消息指示的各个信道与MCS表格的对应关系，确定终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，由于不同类型的信道的传输速率、时延特性等都可能不同，因此基站还可以根据信道的特性配置与各信道匹配的MCS表格，并在广播指示消息中携带各个信道与MCS表格的对应关系发送至终端，以保证各信道中数据的传输速率和可靠性。因此，终端响应于监听到基站发送的广播指示消息，可以从广播指示消息中获取各个信道与MCS表格的对应关系中，确定随机接入过程中各信道使用的MCS表格，并在后续的随机接入过程中根据每次数据传输所使用的信道使用相应的MCS表格。
举例来说，广播指示消息中包括的各个信道与MCS表格的对应关系为：第二随机接入消息与第三随机接入消息对应的MCS表格为第二MCS表格、第四随机接入消息对应的MCS表格为第一MCS表格，因此，终端可以在随机接入过程中向基站发送第三随机接入消息时使用第二MCS表格。
可选的，基站还可以同时根据终端能力、信道特性，确定不同能力终端在不同信道中使用的MCS表格。即在本申请实施例一种可能的实现方式，上述广播指示消息可以用于指示各种能力终端在不同信道与MCS表格的对应关系；相应的，上述步骤301，可以包括：
响应于监听到广播指示消息，确定终端的能力；
根据广播指示消息指示的各种能力终端在不同信道与MCS表格的对应关系及终端的能力，确定终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，由于两种MCS表格的适用场景既可以与终端能力相关，也可以与信道特性相关，因此可以综合考虑终端的能力与信道类型，确定不同终端在不同信道中使用的MCS表格，以进一步提升数据传输的速率和可靠性。因此，基站可以根据终端的能力与信道的特性配置与各种能力终端在各信道中匹配的MCS表格，并在广播指示消息中携带各种能力终端在不同信道与MCS表格的对应关系发送至终端，以进一步提升各种能力终端在各信道中数据的传输速率和可靠性。因此，终端响应于监听到基站发送的广播指示消息，可以从广播指示消息中获取各种能力终端在不同信道与MCS表格的对应关系，并根据自身的终端能力，从各种能力终端在不同信道与MCS表格的对应关系中确定终端在随机接入过程中各信道使用的MCS表格，并在后续的随机接入过程中根据每次数据传输所使用的信道使用相应的MCS表格。
举例来说，广播指示消息中包括的各种能力终端在不同信道与MCS表格的对应关系如表3所示，若终端为第一能力终端1，则在随机接入过程中传输第二随机接入消息与第三随机接入消息时可以使用第二MCS表格，传输第四随机接入消息时可以使用第一MCS表格；若终端为第一能力终端2，则在随机接入过程中传输第二随机接入消息可以使用第二MCS表格，传输第三随机接入消息与第四随机接入消息时可以使用第一MCS表格。
表3
  第二随机接入消息 第三随机接入消息 第四随机接入消息
第一能力终端1 第二表格 第二表格 第一表格
第一能力终端2 第二表格 第一表格 第一表格
可以理解的是，表3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3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3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3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。
作为另一种示例，基站还可以在不需要通知终端在随机接入过程中全部信道或部分信道使用的MCS表格时，通过广播信道向终端发送广播指示消息，以指示终端当前不需要确定随机接入过程中信道使用的MCS表格。从而，终端还可以响应于未监听到广播指示消息，确定终端在随机接入过程中全部或部分信道使用指定的MCS表格。即终端响应于未监听到广播指示消息，可以确定当前需要确定随机接入过程中各信道使用的MCS表格，并根据预先设定的规则确定随机接入过程中各信道使用的MCS表格；并响应于监听到基站发送的广播指示消息，可以根据设置默认使用第一MCS表格或者第二MCS表格。
在本申请的实施例中，步骤301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MCS的配置方法，通过响应于监听到广播指示消息，根据广播指示消息的指示确定终端在随机接入过程中全部或部分信道使用的MCS表格，或者，响应于未监听到广播指示消息，确定终端在随机接入过程中全部或部分信道使用指定的MCS表格。由此，通过根据基站的广播指示消息确定终端在随机接入过程中各信道使用的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
在本申请一种可能的实现形式中，基站还可以通过随机接入过程中的调度信息，通知终端在随机接入过程中各信道使用的MCS表格。
下面结合图4，对本申请实施例提供的又一种MCS的配置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MCS的配置方法的流程示意图，应用于终端。
如图4所示，该MCS的配置方法，包括以下步骤：
步骤401，基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格，其中，指定的策略为基于随机接入过程中的信道指示消息。
作为一种可能的实现方式，基站可以向终端发送第二随机接入消息和/或第四随机接入消息时，在第二随机接入消息和/或第四随机接入消息中指示各信道使用的MCS表格。
可选的，基站可以在第二随机接入消息的PDCCH(Physical Downlink Control Channel，物理下行控制信道)中携带指示第二随机接入消息使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤401，可以包括：
响应于获取到的基站发送的第二随机接入消息的PDCCH中携带的指示信息，确定第二随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第二随机接入消息时，在第二随机接入消息的PDCCH中仅携带指示第二随机接入消息使用的MCS表格的指示信息。因此，终端响应于获取到基站发送的第二随机接入消息，可以从第二随机接入消息的PDCCH中携带的指示信息中，获取第二随机接入消息使用的MCS表格。
可选的，基站还可以在第二随机接入消息的PDCCH中携带指示第二随机接入消息、第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息。即在本申请实施例一种可能的实 现形式中，上述步骤401，可以包括：
响应于获取到的基站发送的第二随机接入消息的PDCCH中携带的指示信息，确定第二随机接入消息和/或第三随机接入消息和/或第四随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第二随机接入消息时，在第二随机接入消息的PDCCH中携带指示第二随机接入消息、第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息。因此，终端响应于获取到基站发送的第二随机接入消息，可以从第二随机接入消息的PDCCH中携带的指示信息中，获取第二随机接入消息、第三随机接入消息与第四随机接入消息使用的MCS表格。
可选的，基站还可以在第二随机接入消息的PDCCH中携带指示第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤401，可以包括：
响应于获取到的基站发送的第二随机接入消息的PDCCH中携带的指示信息，确定第三随机接入消息和/或第四随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第二随机接入消息时，在第二随机接入消息的PDCCH中携带指示第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息。因此，终端响应于获取到基站发送的第二随机接入消息，可以从第二随机接入消息的PDCCH中携带的指示信息中，获取第三随机接入消息与第四随机接入消息使用的MCS表格。
可选的，基站还可以在第四随机接入消息的PDCCH中携带指示第四随机接入消息使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤401，可以包括：
响应于获取到的基站发送的第四随机接入消息的PDCCH中携带的指示信息，确定第四随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第四随机接入消息时，在第四随机接入消息的PDCCH中携带指示第四随机接入消息使用的MCS表格的指示信息。因此，终端响应于获取到基站发送的第四随机接入消息，可以从第四随机接入消息的PDCCH中携带的指示信息中，获取第四随机接入消息使用的MCS表格。
在本申请的实施例中，步骤401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MCS的配置方法，通过基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格，其中，指定的策略为基于随机接入过程中的信道指示消息。由此，通过根据基站在随机接入过程中发送的信道指示消息确定终端在随机接入过程中各信道使用的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
在本申请一种可能的实现形式中，基站还可以通过预设的规则，比如通过根据终端对RSRP(Reference Signal Receiving Power，参考信号接收功率)当前的测量值，确定终端在随机接入过程中各信道使用的MCS表格。
下面结合图5，对本申请实施例提供的又一种MCS的配置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MCS的配置方法的流程示意图，应用于终端。
如图5所示，该MCS的配置方法，包括以下步骤：
步骤501，确定终端当前对应的参考信号接收功率RSRP当前的测量值。
作为一种可能的实现方式，还可以预先配置确定MCS表格的规则，从而在终端的随机接入过程中，可以根据预先配置的规则，确定各信道使用的MCS表格。比如，预先配置的规则可以是根据RSRP当前的测量值，确定终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，由于终端对RSRP当前的测量值可以反映终端当前的用户能力，以及终端当前的实际传输性能，因此，可以根据RSRP当前的测量值，确定在随机接入过程中各信道使用的MCS表格，以更加符合终端当前的实时性能需求。因此，终端可以在随机接入过程中对RSRP进行测量，以根 据RSRP当前的测量值所处的范围，确定在随机接入过程中各信道使用的MCS表格。
进一步的，终端在测量出RSRP的当前的测量值之后，可以将RSRP当前的测量值发送至基站，以使基站确定与RSRP当前的测量值匹配的各信道使用的MCS表格。即在本申请实施例一种可能的实现方式中，上述步骤501之后，还可以包括：
根据RSRP当前的测量值，确定向基站发送的第一随机接入消息中PRACH资源的标识，其中，PRACH资源的标识用于表征终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，由于终端在随机接入过程中，会向基站发送第一随机接入消息，因此终端可以在向基站发送第一随机接入消息时，根据RSRP当前的测量值确定第一随机接入消息中的PRACH资源的标识，以通过第一随机接入消息中的PRACH资源的标识指示RSRP当前的测量值。从而，基站在获取到第一随机接入消息之后，可以根据第一接入消息中的PRACH资源的标识确定RSRP当前的测量值，以根据RSRP当前的测量值确定在随机接入过程中各信道使用的MCS表格。
在本申请的实施例中，步骤501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502，根据RSRP当前的测量值，确定终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，终端对RSRP当前的测量值，可以反映终端当前的实际传输性能。具体的，终端对RSRP当前的测量值越小，说明终端的能力或者当前的实际传输性能越差；反之，则说明终端的能力或者当前的实际传输性能越好。即在本申请实施例一种可能的实现方式中，上述步骤502，可以包括：
响应于RSRP当前的测量值小于第一阈值，确定终端在随机接入过程中全部或部分信道使用第一MCS表格；
或者，
响应于在RSRP当前的测量值大于或等于第一阈值，确定终端在随机接入过程中全部或部分信道使用第二MCS表格；
其中，不少于1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。
在本申请实施例中，响应于RSRP当前的测量值小于第一阈值，可以确定终端的能力或当前的实际传输性能较差，从而可以确定终端在随机接入过程中全部或部分信道使用频谱效率较低的第一MCS表格；响应于RSRP当前的测量值大于或等于第一阈值，可以确定终端的能力或当前的实际传输性能较好，从而可以确定终端在随机接入过程中全部或部分信道使用频谱效率较高的第二MCS表格。
需要说明的是，在本申请实施例中，可以同时限定响应于RSRP当前的测量值小于第一阈值，终端在随机接入过程中全部或部分信道使用第一MCS表格，以及响应于RSRP当前的测量值大于或等于第一阈值，终端在随机接入过程中全部或部分信道使用第二MCS表格。
或者，也可以仅限定响应于RSRP当前的测量值小于第一阈值，终端在随机接入过程中全部或部分信道使用第一MCS表格，而对响应于RSRP当前的测量值大于或等于第一阈值使用的MCS表格不做限定。比如，响应于RSRP当前的测量值大于或等于第一阈值，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
或者，也可以仅限定响应于RSRP当前的测量值大于或等于第一阈值，终端在随机接入过程中全部或部分信道使用第二MCS表格，而对响应于RSRP当前的测量值小于第一阈值使用的MCS表格不做限定。比如，响应于RSRP当前的测量值小于第一阈值，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
作为一种可能的实现方式，终端在根据RSRP当前的测量值，确定终端在随机接入过程中全部或部分信道使用的MCS表格时，可以是将RSRP当前的测量值通过第一随机接入消息同步至基站后，根据基站发送的广播指示消息或信道指示消息确定的，本申请实施例对此不做限定。
本申请实施例提供的MCS的配置方法，通过确定终端当前对应的RSRP当前的测量值，并根据RSRP当前的测量值，确定终端在随机接入过程中全部或部分信道使用的MCS表格。由此，通过根据 终端对应的RSRP的实时测量值，实时确定终端在随机接入过程中各信道使用的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
图6为本申请实施例所提供的另一种MCS的配置方法的流程示意图，应用于网络设备侧，比如基站。
如图6所示，该MCS的配置方法，包括以下步骤：
步骤601，基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格，其中，指定的策略包括以下策略中的任意一种：终端的能力、指示消息及预先配置的规则。
需要说明的是，本申请实施例的MCS的配置方法可以应用在任意的终端中。终端可以是指向用户提供语音和/或数据连通性的设备。终端可以经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)、用户代理(useragent)、用户设备(user device)、或UE。或者，终端也可以是无人飞行器的设备。或者，终端也可以是车载设备，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，终端也可以是路边设备，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。
其中，随机接入过程中的信道，可以包括传输第一随机接入消息(Msg.1)的信道、传输第二随机接入消息(Msg.2)的信道、传输第三随机接入消息(Msg.3)的信道、传输第四随机接入消息(Msg.4)的信道，等等。
需要说明的是，由于在终端的随机接入过程中，终端与基站之间进行数据传输的各信道也会出现覆盖损失，因此也可以通过在随机接入过程中配置各信道所使用的MCS表格的方式，来进行覆盖增强，以提升随机接入过程中的数据传输质量。但是，MCS表格的配置是由RRC完成的，而在终端的随机接入过程中RRC连接还没有建立，从而无法通过RRC实现随机接入过程中的MCS表格的配置。因此，在本申请实施例中，可以在终端的随机接入过程中，重新设置MCS表格的配置策略，以实现随机接入过程中各信道使用的MSC表格。
在本申请的所有实施例中，对于需要进行覆盖增强的终端来说，有两个可用的MCS表格。其中一个示例性的可以用于覆盖终端能力较好的情况或其他恰当的情况，另一个示例性的可以用于覆盖终端能力较差或者传输要求较高(比如对误码率要求较高)的情况或其他恰当的情况。在本申请的所有实施例中，在本公开的所有实施例中，至少1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。比如，两种MCS表格可以是如表1所示的第一MCS表格和表2所示的第二MCS表格。
作为一种可能的实现方式，由于两种MCS表格的适用场景和终端能力相关，因此在终端的随机接入过程中，基站可以根据终端能力配置与终端能力相适应的MCS表格，并根据当前终端与基站的通信进程，在相应的信道中使用确定的MCS表格。
作为另一种可能的实现方式，还可以通过基站设置各信道使用的MCS表格，因此，基站可以向终端发送指示消息，以通知终端在随机接入过程中使用的MCS表格。
作为再一种可能的实现方式，基站还可以预先配置确定MCS表格的规则，从而在终端的随机接入过程中，可以根据预先配置的规则，确定各信道使用的MCS表格。比如，预先配置的规则可以是随机接入过程中各信道与MCS表格的映射关系，本申请实施例对此不做限定。
在本申请的实施例中，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。
本申请实施例提供的MCS的配置方法，通过基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格；其中，指定的策略包括以下策略中的任意一种：终端的能力、指示消息及 预先配置的规则。由此，通过预先设置用于在终端的随机接入过程中配置MCS表格的指定策略，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强。
在本申请一种可能的实现形式中，可以在终端的随机接入过程中使用与终端能力相配的MCS表格，以提升随机接入过程中数据传输的可靠性。
下面结合图7，对本申请实施例提供的再一种MCS的配置方法进行进一步说明。
图7为本申请实施例所提供的再一种MCS的配置方法的流程示意图，应用于网络侧，比如基站。
如图7所示，该MCS的配置方法，包括以下步骤：
步骤701，响应于获取到的终端发送的第一随机接入消息，确定第一随机接入消息中的PRACH资源的标识。
步骤702，根据第一随机接入消息中的PRACH资源的标识，确定终端的能力。
作为一种可能的实现方式，由于两种MCS表格的适用场景和终端能力相关，因此指定的策略可以是终端能力，从而在终端的随机接入过程中，可以根据终端能力确定与终端能力相适应的MCS表格，并根据当前终端与基站的通信进程，在相应的信道中使用确定的MCS表格。
作为一种可能的实现方式，由于终端在随机接入过程中，会向基站发送第一随机接入消息，因此终端可以在向基站发送第一随机接入消息时，根据终端的能力确定第一随机接入消息中的PRACH资源的标识，以通过第一随机接入消息中的PRACH资源的标识指示终端为第一能力终端还是第二能力终端。从而，基站在获取到第一随机接入消息之后，可以获取第一接入消息中的PRACH资源的标识，以确定终端的能力。
在本申请实施例中，基站在获取到第一随机接入消息之后，可以根据第一接入消息中的PRACH资源的标识确定终端的能力，并响应于确定终端为第一能力终端，确定在随机接入过程中传输第二随机接入消息、第三随机接入消息、第四随机接入消息时，均使用第一MCS表格；响应于终端为第二能力终端，确定在随机接入过程中传输第二随机接入消息、第三随机接入消息、第四随机接入消息时，均使用第二MCS表格。
步骤703，响应于终端为第一能力终端，确定终端在随机接入过程中全部或部分信道使用第一MCS表格。
其中，第一能力终端，可以是用户能力较低的终端；相对来说，第一能力终端的用户能力可以比第二能力终端的用户能力低。用户能力可以包括接收天线的个数与接收带宽中的任意一项。比如，第一能力终端可以是应用在5G新空口模式中的Redcap终端，第二能力终端可以是应用在LTE或5G或任何一代通讯系统中的普通终端，本申请实施例对此不做限定。
在本申请实施例中，由于第一能力终端的用户能力不足，因此基站响应于终端为第一能力终端，可以确定在随机接入过程中使用频谱效率较低的第一MCS表格，比如，可以是如表1所示的第一MCS表格。
步骤704，响应于终端为第二能力终端，确定终端在随机接入过程中全部或部分信道使用第二MCS表格，其中，至少不少于1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。
在本申请实施例中，由于第二能力终端的用户能力较好，因此基站响应于确定终端为第二能力终端，可以确定在随机接入过程中使用频谱效率较高的第二MCS表格。比如，可以是如表2所示的第二MCS表格。
需要说明的是，在本申请实施例中，基站可以同时限定第一能力终端在随机接入过程中全部或部分信道使用第一MCS表格，以及第二能力终端在随机接入过程中全部或部分信道使用第二MCS表格。
或者，基站也可以仅限定第一能力终端在随机接入过程中全部或部分信道使用第一MCS表格，而对第二能力终端使用的MCS表格不做限定。比如，响应于终端为第二能力终端，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
或者，基站也可以仅限定第二能力终端在随机接入过程中全部或部分信道使用第二MCS表格，而对第一能力终端使用的MCS表格不做限定。比如，响应于终端为第一能力终端，在随机接入过程中可 以随机使用第一MCS表格或者第二MCS表格。
本申请实施例提供的MCS的配置方法，通过响应于终端为第一能力终端，确定终端在随机接入过程中全部或部分信道使用第一MCS表格，或者，响应于终端为第二能力终端，确定终端在随机接入过程中全部或部分信道使用第二MCS表格。在本公开的所有实施例中，至少1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。由此，通过根据终端的能力在随机接入过程中配置与终端能力相匹配的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
在本申请一种可能的实现形式中，基站还可以通过广播的形式通知终端在随机接入过程中各信道使用的MCS表格。
下面结合图8，对本申请实施例提供的又一种MCS的配置方法进行进一步说明。
图8为本申请实施例所提供的又一种MCS的配置方法的流程示意图，应用于网络侧，比如基站。
如图8所示，该MCS的配置方法，包括以下步骤：
步骤801，响应于确定终端在随机接入过程中全部或部分信道使用的MCS表格，发送广播指示消息。
作为另一种可能的实现方式，可以通过基站设置各信道使用的MCS表格，因此，基站可以通过广播的方式通知终端在随机接入过程中全部信道或部分信道使用的MCS表格，即指示消息可以为广播指示消息。
作为一种示例，基站可以在需要通知终端在随机接入过程中全部信道或部分信道使用的MCS表格时，通过广播信道向终端发送广播指示消息。因此，终端响应于监听到基站发送的广播指示消息，可以根据广播指示消息的指示确定终端在随机接入过程中全部或部分信道使用的MCS表格；响应于未监听到基站发送的广播指示消息，可以根据设置默认使用第一MCS表格或者第二MCS表格。
在本申请实施例一种可能的实现形式中，广播指示消息用于指示以下信息中的至少一种：各种能力终端与MCS表格的对应关系、各个信道与MCS表格的对应关系、各种能力终端在不同信道与MCS表格的对应关系。
可选的，在广播指示消息中可以用于指示各种能力终端与MCS表格的对应关系时，基站可以根据自身的策略确定各种能力终端在随机接入过程中使用的MCS表格，并在广播指示消息中携带各种能力终端与MCS表格的对应关系并发送至终端。比如，广播指示消息中包括的各种能力终端与MCS表格的对应关系可以为：第一能力终端与第一MCS表格对应、第二能力终端与第二MCS表格对应。
可选的，在广播指示消息中还可以用于指示各个信道与MCS表格的对应关系时，由于不同类型的信道的传输速率、时延特性等都可能不同，因此基站还可以根据信道的特性配置与各信道匹配的MCS表格，并在广播指示消息中携带各个信道与MCS表格的对应关系发送至终端，以保证各信道中数据的传输速率和可靠性。比如，广播指示消息中包括的各个信道与MCS表格的对应关系可以为：第二随机接入消息与第三随机接入消息对应的MCS表格为第二MCS表格、第四随机接入消息对应的MCS表格为第一MCS表格。
可选的，基站还可以同时根据终端能力、信道特性，确定不同能力终端在不同信道中使用的MCS表格。即广播指示消息可以用于指示各种能力终端在不同信道与MCS表格的对应关系。在本申请实施例中，由于两种MCS表格的适用场景既可以与终端能力相关，也可以与信道特性相关，因此可以综合考虑终端的能力与信道类型，确定不同终端在不同信道中使用的MCS表格，以进一步提升数据传输的速率和可靠性。因此，基站可以根据终端的能力与信道的特性配置与各种能力终端在各信道中匹配的MCS表格，并在广播指示消息中携带各种能力终端在不同信道与MCS表格的对应关系发送至终端，以进一步提升各种能力终端在各信道中数据的传输速率和可靠性。比如，广播指示消息中包括的各种能力终端在不同信道与MCS表格的对应关系可以如表3所示。
作为另一种示例，基站还可以在不需要通知终端在随机接入过程中全部信道或部分信道使用的MCS表格时，通过广播信道向终端发送广播指示消息，以指示终端当前不需要确定随机接入过程中信 道使用的MCS表格；并在确定需要通知终端在随机接入过程中全部信道或部分信道使用的MCS表格时，不发送广播指示信息。从而，基站可以响应于确定终端在随机接入过程中全部或部分信道使用的MCS表格，不发送广播消息。即终端可以响应于未监听到广播指示消息，确定当前需要确定随机接入过程中各信道使用的MCS表格，并根据预先设定的规则确定随机接入过程中各信道使用的MCS表格；并响应于监听到基站发送的广播指示消息，可以根据设置默认使用第一MCS表格或者第二MCS表格。
在本申请的实施例中，步骤801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MCS的配置方法，通过响应于确定终端在随机接入过程中全部或部分信道使用的MCS表格，发送广播指示消息，或者，响应于确定终端在随机接入过程中全部或部分信道使用的MCS表格，不发送广播消息。由此，通过根据基站的广播指示消息确定终端在随机接入过程中各信道使用的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
在本申请一种可能的实现形式中，基站还可以通过随机接入过程中的调度信息，通知终端在随机接入过程中各信道使用的MCS表格。
下面结合图9，对本申请实施例提供的又一种MCS的配置方法进行进一步说明。
图9为本申请实施例所提供的又一种MCS的配置方法的流程示意图，应用于网络侧，比如基站。
如图9所示，该MCS的配置方法，包括以下步骤：
步骤901，基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格，其中，指定的策略为基于随机接入过程中的信道指示消息。
作为一种可能的实现方式，基站可以向终端发送第二随机接入消息和/或第四随机接入消息时，在第二随机接入消息和/或第四随机接入消息中指示各信道使用的MCS表格。
可选的，基站可以在第二随机接入消息的PDCCH中携带指示第二随机接入消息使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤901，可以包括：
在发送的第二随机接入消息的PDCCH中携带用于指示第二随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第二随机接入消息时，根据自身策略在第二随机接入消息的PDCCH中仅携带指示第二随机接入消息使用的MCS表格的指示信息，以使终端在获取到基站发送的第二随机接入消息时，可以从第二随机接入消息的PDCCH中携带的指示信息中，获取第二随机接入消息使用的MCS表格。
可选的，基站还可以在第二随机接入消息的PDCCH中携带指示第二随机接入消息、第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤901，可以包括：
在发送的第二随机接入消息的PDCCH中携带用于指示第二随机接入消息和/或第三随机接入消息和/或第四随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第二随机接入消息时，在第二随机接入消息的PDCCH中携带指示第二随机接入消息、第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息，以使终端在获取到基站发送的第二随机接入消息时，可以从第二随机接入消息的PDCCH中携带的指示信息中，获取第二随机接入消息、第三随机接入消息与第四随机接入消息使用的MCS表格。
可选的，基站还可以在第二随机接入消息的PDCCH中携带指示第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤901，可以包括：
在发送的第二随机接入消息的PDCCH中携带用于指示第三随机接入消息和/或第四随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第二随机接入消息时，在第二随机接入消息的PDCCH中携带指示第三随机接入消息与第四随机接入消息中的至少一种使用的MCS表格 的指示信息，以使终端在获取到基站发送的第二随机接入消息时，可以从第二随机接入消息的PDCCH中携带的指示信息中，获取第三随机接入消息与第四随机接入消息使用的MCS表格。
可选的，基站还可以在第四随机接入消息的PDCCH中携带指示第四随机接入消息使用的MCS表格的指示信息。即在本申请实施例一种可能的实现形式中，上述步骤901，可以包括：
在发送的第四随机接入消息的PDCCH中携带用于指示第四随机接入消息使用的MCS表格。
在本申请实施例中，基站可以在随机接入过程中，在向终端发送第四随机接入消息时，在第四随机接入消息的PDCCH中携带指示第四随机接入消息使用的MCS表格的指示信息，以使终端在获取到基站发送的第四随机接入消息时，可以从第四随机接入消息的PDCCH中携带的指示信息中，获取第四随机接入消息使用的MCS表格。
在本申请的实施例中，步骤901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MCS的配置方法，通过基于指定的策略，确定终端在随机接入过程中全部或部分信道使用的MCS表格，其中，指定的策略为基于随机接入过程中的信道指示消息。由此，通过根据基站在随机接入过程中发送的信道指示消息确定终端在随机接入过程中各信道使用的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
在本申请一种可能的实现形式中，基站还可以通过预设的规则，比如通过根据终端对RSRP当前的测量值，确定终端在随机接入过程中各信道使用的MCS表格。
下面结合图10，对本申请实施例提供的另一种MCS的配置方法进行进一步说明。
图10为本申请实施例所提供的另一种MCS的配置方法的流程示意图，应用于网络侧，比如基站。
如图10所示，该MCS的配置方法，包括以下步骤：
步骤1001，响应于获取到的第一随机接入消息中的PRACH资源的标识，确定终端对应的RSRP当前的测量值。
作为一种可能的实现方式，还可以预先配置确定MCS表格的规则，从而在终端的随机接入过程中，可以根据预先配置的规则，确定各信道使用的MCS表格。比如，预先配置的规则可以是根据RSRP当前的测量值，确定终端在随机接入过程中全部或部分信道使用的MCS表格。
在本申请实施例中，由于终端对RSRP当前的测量值可以反映终端当前的用户能力，以及终端当前的实际传输性能，因此，可以根据RSRP当前的测量值，确定在随机接入过程中各信道使用的MCS表格，以更加符合终端当前的实时性能需求。因此，终端可以在随机接入过程中对RSRP进行测量，以根据RSRP当前的测量值所处的范围，确定在随机接入过程中各信道使用的MCS表格。
在本申请实施例中，终端在测量出RSRP的当前的测量值之后，可以将RSRP当前的测量值发送至基站，以使基站确定与RSRP当前的测量值匹配的各信道使用的MCS表格。具体的，由于终端在随机接入过程中，会向基站发送第一随机接入消息，因此终端可以在向基站发送第一随机接入消息时，根据RSRP当前的测量值确定第一随机接入消息中的PRACH资源的标识，以通过第一随机接入消息中的PRACH资源的标识指示RSRP当前的测量值。从而，基站在获取到第一随机接入消息之后，可以根据第一接入消息中的PRACH资源的标识确定RSRP当前的测量值，以根据RSRP当前的测量值确定在随机接入过程中各信道使用的MCS表格。
在本申请的实施例中，步骤1001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1002，响应于RSRP当前的测量值小于第一阈值，确定终端在随机接入过程中全部或部分信道使用第一MCS表格。
步骤1003，响应于RSRP当前的测量值大于或等于第一阈值，确定终端在随机接入过程中全部或部分信道使用第二MCS表格，其中，至少不少于1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。
在本申请实施例中，终端对RSRP当前的测量值，可以反映终端当前的实际传输性能。具体的，终 端对RSRP当前的测量值越小，说明终端的能力或者当前的实际传输性能越差；反之，则说明终端的能力或者当前的实际传输性能越好。因此，响应于RSRP当前的测量值小于第一阈值，可以确定终端的能力或当前的实际传输性能较差，从而可以确定终端在随机接入过程中全部或部分信道使用频谱效率较低的第一MCS表格；响应于RSRP当前的测量值大于或等于第一阈值，可以确定终端的能力或当前的实际传输性能较好，从而可以确定终端在随机接入过程中全部或部分信道使用频谱效率较高的第二MCS表格。
需要说明的是，在本申请实施例中，基站可以同时限定响应于RSRP当前的测量值小于第一阈值，终端在随机接入过程中全部或部分信道使用第一MCS表格，以及响应于RSRP当前的测量值大于或等于第一阈值，终端在随机接入过程中全部或部分信道使用第二MCS表格。
或者，基站也可以仅限定响应于RSRP当前的测量值小于第一阈值，终端在随机接入过程中全部或部分信道使用第一MCS表格，而对响应于RSRP当前的测量值大于或等于第一阈值使用的MCS表格不做限定。比如，响应于RSRP当前的测量值大于或等于第一阈值，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
或者，基站也可以仅限定响应于RSRP当前的测量值大于或等于第一阈值，终端在随机接入过程中全部或部分信道使用第二MCS表格，而对响应于RSRP当前的测量值小于第一阈值使用的MCS表格不做限定。比如，响应于RSRP当前的测量值小于第一阈值，在随机接入过程中可以随机使用第一MCS表格或者第二MCS表格。
作为一种可能的实现方式，基站在根据RSRP当前的测量值，确定终端在随机接入过程中全部或部分信道使用的MCS表格时，可以在确定出随机接入过程中全部或部分信道使用的MCS表格后，通过广播指示消息或信道指示消息发送至终端。
本申请实施例提供的MCS的配置方法，通过在获取到的第一随机接入消息中的PRACH资源的标识，确定终端对应的RSRP当前的测量值，并响应于RSRP当前的测量值小于第一阈值，确定终端在随机接入过程中全部或部分信道使用第一MCS表格，或者，响应于RSRP当前的测量值大于或等于第一阈值，确定终端在随机接入过程中全部或部分信道使用第二MCS表格。在本公开的所有实施例中，至少1个相同的MCS索引在第一MCS表格中对应的频谱效率小于在第二MCS表格中对应的频谱效率。由此，通过根据终端对应的RSRP的实时测量值，实时确定终端在随机接入过程中各信道使用的MCS表格，使得在随机接入过程中也可以根据需求对MCS表格进行配置，从而实现了随机接入过程中的覆盖增强，进一步提升了随机接入过程中数据传输的可靠性。
