现有技术中,MTC UE在上行链路数据发送/下行链路数据接收之前,通过基站发送的资源分配字段获取资源分配信息及根据调制与编码策略(Modulation and Coding Scheme,MCS)字段获取MCS信息,之后再根据MCS信息和资源分配信息查询资源分配信息表,从而获取到基站为该MTC UE分配的传输块大小,由于现有的TBS表只包括正交相移键控(Quadrature Phase Shift Keyin,QPSK)调制模式,从而使用QPSK调制模式,在上行子载波上根据所确定的传输块大小发送上行信号。然而,当调制模式为其他调制模式(如Pi/2 BPSK调制模式)时,该MTC UE如何确定对应的传输块大小,及如何根据所确定的传输大小完成上行信号的传输是本领域技术人员亟待解决的问题。

为了解决现有技术在存在的当调制模式为其他调制模式(如Pi/2 BPSK调制模式)时,如何确定对应的传输块大小,及如何根据所确定的传输大小传输上行信号的问题,本申请实施例提供了一种上行信号的发送方法,使得终端设备在发送上行信号之前,先接收网络设备发送的下行控制信息DCI,并根据DCI确定用于传输上行信号的传输块大小TBS;在确定传输块大小之后,使用Pi/2 BPSK调制模式,在两个连续的上行子载波上,根据所确定的传输块大小发送上行信号,从而实现Pi/2 BPSK调制模式下,使用确定的传输块大小完成上行信号的传输。相应地,使得网络设备可以对在两个连续的上行子载波上接收到的上行信号使用Pi/2 BPSK调制模式对所述上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
请参见图2所示,图2为本申请实施例提供的一种上行信号的发送方法的示意图,该上行信号的发送方法可以包括:
S201、终端设备接收网络设备发送的下行控制信息DCI。
S202、终端设备根据DCI确定用于传输上行信号的传输块大小TBS。
S203、终端设备使用Pi/2 BPSK调制模式,在两个连续的上行子载波上,根据所确定的传输块大小发送上行信号。
其中,两个连续的子载波可以是三个连续的子载波中的相邻的两个,两个子载波在三个子载波的位置是小区级统一的,可以是固定的值,也可以是高层信令/RRC信令配置的。
需要说明的是,在本申请实施例中,终端设备在使用确定的传输块大小发送上行信号之前,可以通过以下至少三种可能的实现方式确定用于传输该上行信号的传输块大小。在一种可能的实现方式中,以指示索引指示信息的字段为4比特为例,对应有16个MCS索引,可以通过空闲的S个MCS索引指示Pi/2 BPSK调制模式,并先根据DCI中索引指示信息指示的MCS索引和第一映射关系确定其对应的TBS索引,再根据该TBS索引和资源单元个数指示信息确定用于传输上行信号的传输块大小。在第二种可能的实现方式中,终端设备需要先根据DCI中索引指示信息指示的MCS索引和第二映射关系确定其对应的TBS索引,再根据TBS索引、资源单元个数指示信息、载波个数指示信息和/或调制模式信息,确定用于传输上行信号的传输块大小TBS。在第三种可能的实现方式中,终端设备可以根据DCI中的索引指示信息直接确定用于传输上行信号的传输块大小TBS,该索引指 示信息和传输传输块大小之间具有映射关系。
为了更清楚地说明上述三种可能的实现方式,下面,将以具体的实施例对上述三种可能的实现方式进行详细描述。
在第一种可能的实现方式中,若终端设备接收到的DCI包括索引指示信息和资源单元个数指示信息,且索引指示信息用于指示MCS索引时,终端设备可以先根据索引指示信息指示的MCS索引和第一映射关系确定其对应的TBS索引,再根据TBS索引和资源单元个数指示信息确定用于传输上行信号的传输块大小。
其中,第一映射关系用于指示MCS索引、调制模式及TBS索引之间的关系。可选的,该第一映射关系可以包括第一部分和第二部分,第一部分用于指示MCS索引、QPSK调制模式及TBS索引的关系,第二部分用于指示TBS索引、Pi/2 BPSK调制模式及TBS索引的关系,进一步地,第二部分可以包括S个TBS索引,和/或,第二部分的传输块大小的最大值为936或1000,从而实现两个连续的上行子载波可支持的最大传输块个数为936或1000。
可选的,第二部分中的S个TBS索引为第一部分中的S个TBS索引。需要说明的是,第一部分中的TBS索引和资源单元个数指示信息对应的传输块大小是预先设置的。
在根据第二部分中的TBS索引确定用于传输上行信号的传输块大小时,需要先确定该第二部分中的S个TBS索引,可选的,该S个TBS索引可以为第一部分中的任意S个TBS索引,在确定第二部分中的TBS索引之后,则第二部分中的传输块大小也随之确定。
同样以指示索引指示信息的字段包括4比特为例,则对应16个MCS索引,其中,现有标准规定了0至10共11个MCS索引对应的QPSK调制模式、TBS索引之间的关系,在本申请实施例中,可以将未使用的S个MCS索引设置为Pi/2 BPSK调制模式对应的S个索引,其中S为正整数,S大于2且小于等于5。需要说明的是,若第一部分的MCS索引为16个MCS索引的前11个时(即MCS索引0至10),则未使用的S个MCS索引可以为16个MCS索引的后面S个,即MCS索引11至(11+S-1),当然,若第一部分的MCS索引为16个MCS索引的后11个时(即MCS索引5至15),则未使用的S个MCS索引可以为16个MCS索引的前面S个,即MCS索引(0+5-S)至4。
可选的,该第二部分中的TBS索引可以为第一部分中的TBS索引0至11中的任一值,但为了分布均匀,可以等间隔取第一部分中的TBS索引作为第二部分中MCS索引对应的TBS索引,当然,也可以非等间隔取第一部分中的TBS索引作为第二部分中MCS索引对应的TBS索引,下面将具体描述如何确定第二部分中的S个TBS索引。
在第一种情况下,当第一部分的MCS索引包括0至10时;则第二部分的MCS索引包括11至(11+S-1),当S=3时,请参见表1所示:

此外,第二部分中的MCS索引0也可以对应TBS索引0,MCS索引1对应TBS索引2,MCS索引2对应TBS索引5,MCS索引3对应TBS索引7,MCS索引4对应TBS索引9,请参见表18所示:

需要说明的是,上述表1-表18中的MCS索引只是以0开始为例进行说明,当然,也可以从1开始,具体可以根据实际需要进行设置,只要可以根据MCS索引查找到表中所有可能的调制模式和TBS索引组合即可。当然,在网络设备、终端设备和芯片以及装置中也可以通过集合的形式体现上面的表格,即将上面表格中的所有MCS索引对应的调制模式和TBS索引组合组成一个集合,通过MCS索引查找该集合中的某一个调制模式和TBS索引组合。
综上,在通过上述表格确定第二部分中的MCS索引对应的TBS索引之后,就可以根据TBS索引和资源单元个数确定对应的传输块大小。可选的,在根据TBS索引和资源单元个数确定对应的传输块大小时,当索引指示信息指示的MCS的索引属于第一部分和资源单元格个数为N时,终端设备根据现有标准设置的TBS表格中第K个物理资源块(PRB)对应的列和索引指示信息指示的TBS索引确定TBS,即该TBS是根据现有标准设置的TBS表格中第K个物理资源块(PRB)对应的列和索引指示信息指示的TBS索引确定的。当索引指示信息指示的MCS的索引属于第二部分和资源单元格个数为2*N时,终端设备根据现有标准设置的TBS表格中第K个物理资源块(PRB)对应的列和索引指示信息指示的TBS索引确定TBS,即TBS是根据现有标准设置的TBS表格中第K个物理资源块(PRB)对应的列和索引指示信息指示的TBS索引确定的。其中N和K为正整数。
示例的,在QPSK调制模式下,资源单元个数N可以为1个或2个,若资源单元个数为1个,则根据第一部分中的TBS索引和TBS表格中第3个PRB对应的列查询下述表19,从而确定传输块大小;若资源单元个数为2个,则根据第一部分中的TBS索引和TBS表格中第6个PRB对应的列查询下述表19,从而确定传输块大小。在Pi/2 BPSK调制模式下,资源单元个数为2个或4个,若资源单元个数为2个,则根据第二部分中的TBS索引和TBS表格中第3个PRB对应的列查询下述表19,从而确定传输块大小;若资源单元个数为4个,则根据第二部分中的TBS索引和TBS表格中第6个PRB对应的列查询下述表 19,从而确定用于传输上行信号的传输块大小,请参见表19所示:
表19
由此可见,在该种可能的实现方式,终端设备在根据确定的传输块大小发送上行信号之前,通过接收网络设备发送的DCI,该DCI包括索引指示信息和资源单元个数指示信息,使得终端设备可以先根据该索引指示信息指示的MCS索引和第一映射关系确定对应的TBS索引,再根据TBS索引和资源单元个数指示信息确定用于传输上行信号的传输块大小,并在传输块大小确定之后,使用Pi/2 BPSK调制模式,在两个连续的上行子载波上,根据 所确定的传输块大小发送上行信号,从而实现Pi/2 BPSK调制模式下,使用确定的传输块大小完成上行信号的传输。相应地,使得网络设备可以对在两个连续的上行子载波上接收到的上行信号使用Pi/2 BPSK调制模式对所述上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
需要说明的是,在本申请实施例中,若索引指示信息用于指示MCS索引时,则根据索引指示信息获取到MCS索引之后,还可以包括:
根据该MCS索引确定网络设备分配给终端设备用于传输上行信息的载波个数;载波个数为2个或3/6个。
现有标准支持1个物理资源块PRB的连续6个子载波、连续3个子载波和2个子载波的资源调度,且2个子载波的资源调度中的2个子载波是调度的连续3个子载波中连续的2个子载波,即2和3个子载波的资源调度是相同的,因此,终端设备需要获取采用的是2个子载波的调度还是3个子载波的调度,在本申请实施例中,由于QPSK调制模式对应的资源调度为3个子载波调度和6个子载波调度,而pi/2 BPSK调制模式对应的资源调度为2个子载波调度,又由于QPSK调制模式和pi/2 BPSK调制模式分别于MCS索引之间具有映射关系,因此,可以根据该MCS索引确定pi/2 BPSK调制模式,从而确定为2个子载波调度,进而可以区分2个子载波调度和3个子载波调度。
在第二种可能的实现方式中,终端设备需要先根据DCI中索引指示信息指示的MCS索引和第二映射关系确定其对应的TBS索引,再根据TBS索引、资源单元个数指示信息、载波个数指示信息和/或调制模式信息,确定用于传输上行信号的传输块大小TBS。
其中,第二映射关系用于指示MCS索引和TBS索引的关系。
在该种可能的实现方式中,由于Pi/2 BPSK调制模式与QPSK调制模式复用同一个TBS表格,因此,在确定传输块大小之前,需要预先获取终端设备将要采用的调制模式,在获取该调制模式时,可以通过载波个数指示信息和/或调制模式信息获取调制模式,在通过载波个数指示信息确定调制模式时,若载波个数指示信息指示载波个数为2个,则确定调制模式为pi/2 BPSK调制模式;若载波个数指示信息指示载波个数为3个或6个,则确定调制模式为QPSK调制模式。当然,若通过调制模式信息确定调制模式,则该调制模式可以为QPSK调制模式或pi/2 BPSK调制模式的标识,当然,也可以通过其他方式确定终端设备将要采用的调制模式。
同样以用于指示索引指示信息的字段包括4比特为例,则对应16个MCS索引,其中,现有标准规定了11个MCS索引对应的QPSK调制模式和TBS索引之间的关系,在确定Pi/2 BPSK调制模式下的MCS索引对应的TBS索引时,请参见表20所示,Pi/2 BPSK调制模式与QPSK调制模式复用同一个TBS表格。

结合表20可以看出,当调制模式为Pi/2 BPSK调制模式时,其对应的MCS索引与TBS索引也一一对应,从而可以根据表20中的第二映射关系确定Pi/2 BPSK调制模式下,MCS索引对应的TBS索引。在确定TBS索引之后,就可以根据TBS索引、Pi/2 BPSK调制模式及资源单元指示信息指示的资源单元个数确定用于传输上行信号的传输块大小TBS。
可选的,当调制模式为QPSK调制模式,资源单元个数指示信息指示的资源单元个数为P时,终端设备根据标准已设置的TBS表格中第M个资源单元对应的列和索引指示信息对应的TBS索引确定用于传输上行信号的传输块大小TBS。
当调制模式为Pi/2 BPSK调制模式,资源单元个数指示信息指示的资源单元个数为2*P时,终端设备根据标准已设置的TBS表格中第M个资源单元对应的列和索引指示信息对应的TBS索引确定用于传输上行信号的传输块大小TBS,其中M和P为正整数。
示例的,请结合上述表19所示,在QPSK调制模式下,资源单元个数N可以为1个或2个,若资源单元个数为1个,则根据TBS索引和TBS表格中第3个PRB对应的列查询上述表7,从而确定传输块大小;若资源单元个数为2个,则根据TBS索引和TBS表格中第6个PRB对应的列查询上述表19,从而确定传输块大小。在Pi/2 BPSK调制模式下,资源单元个数为2个或4个,若资源单元个数为2个,则根据TBS索引和TBS表格中第3个PRB对应的列查询上述表19,从而确定传输块大小;若资源单元个数为4个,则根据TBS索引和TBS表格中第6个PRB对应的列查询上述表19,从而确定用于传输上行信号的传输块大小,请参见下述表21所示,可选的,TBS的最大值为936、1000或1032,从而实现两个连续的上行子载波可支持的最大传输块个数为936或1000。
需要说明的是,上述表20中的MCS索引只是以0开始为例进行说明,当然,也可以从1开始,具体可以根据实际需要进行设置,只要可以根据该MCS索引查找到其对应的TBS索引即可。当然,在网络设备、终端设备和芯片以及装置中也可以通过集合的形式体现上面的表格,即将上面表格中的所有MCS索引对应的TBS索引组成一个集合,通过MCS索引查找该集合中的某一个TBS索引。
由此可见,在该种可能的实现方式,终端设备在根据确定的传输块大小发送上行信号之前,通过接收网络设备发送的DCI,该DCI包括载波个数指示信息和/或调制模式信息、索引指示信息、资源单元个数指示信息,使得终端设备可以根据索引指示信息指示的MCS索引和第二映射关系确定对应的TBS索引,且根据载波个数指示信息和/或调制模式信息确定调制模式,再根据TBS索引、调制模式及资源单元个数指示信息确定用于传输上行信号的传输块大小,并在传输块大小确定之后,使用Pi/2 BPSK调制模式,在两个连续的上行子载波上,根据所确定的传输块大小发送上行信号,从而实现Pi/2 BPSK调制模式下,使用确定的传输块大小完成上行信号的传输。相应地,使得网络设备可以对在两个连续的 上行子载波上接收到的上行信号使用Pi/2 BPSK调制模式对所述上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
在第三种可能的实现方式中,终端设备根据DCI中的索引指示信息直接确定用于传输上行信号的传输块大小TBS,其中,索引指示信息与传输块大小之间具有映射关系。
其中,DCI包含索引指示信息,且该索引指示信息与传输块大小之间有映射关系。
以用于指示索引指示信息的字段为4比特为例,最多能对应16个索引指示信息,请结合下述表21所示,表21中第二列中总共有22个传输块大小。其中有两个208、两个256、两个328、两个504等,可以删掉两个相等中的任一个,即每一个组相等的两个数中只保留一个,此时还剩下17个传输块大小,还需要再从剩余的17个中删掉一个。示例的,在本申请实施例中,可以根据传输块大小之间的接近程度进行删除。在本申请实施例中,由于144和152比较接近,可以删掉144和152其中一个,或者,由于408和392比较接近,可以删掉408和392其中一个,从而剩下16个传输块大小,该索引指示信息与传输块大小之间的映射关系可以应用于Pi/2 BPSK调制模式。示例的,索引指示信息可以用于指示索引,在确定16个索引对应的16个传输块大小时,可以删除408,请参见表22所示:
表21

13 | Pi/2 BPSK | 712 |
14 | Pi/2 BPSK | 808 |
15 | Pi/2 BPSK | 936 |
结合表22可以看出,在17个值中删除408之后,剩余16个传输块大小,由于索引与传输块大小一一对应,则终端设备可以直接根据索引指示信息确定用于传输上行信号的传输块大小。
当然,在确定16个索引对应的16个传输块大小时,也可以删除152,请参见表23所示:
表23

13 | Pi/2 BPSK | 712 |
14 | Pi/2 BPSK | 808 |
15 | Pi/2 BPSK | 936 |
结合表23可以看出,在17个值中删除152之后,剩余16个1传输块大小1,由于索引与传输块大小一一对应,则终端设备可以直接根据索引指示信息确定用于传输上行信号的传输块大小。
此外,在确定16个索引对应的16个传输块大小时,还可以删除144,请参见表24所示:
表24

13 | Pi/2 BPSK | 712 |
14 | Pi/2 BPSK | 808 |
15 | Pi/2 BPSK | 936 |
结合表24可以看出,在17个值中删除144之后,剩余16个传输块大小,由于索引与传输块大小一一对应,则终端设备可以直接根据索引指示信息确定用于传输上行信号的传输块大小。
可选的,所属用于指示索引指示信息的字段可以为现有标准中DCI Format 6-0B或者DCI Format 6-0A中的用于指示MCS索引的字段。
需要说明的是,上述表22-表24中的索引只是以0开始为例进行说明,当然,也可以从1开始,具体可以根据实际需要进行设置,只要可以根据该索引查找到上述表格中的传输块大小即可。当然,在网络设备、终端设备和芯片以及装置中也可以通过集合的形式体现上面的表格,即将上面表格中的所有索引对应的TBS组成一个集合,通过索引查找该集合中的某一个TBS。
由此可见,在该种可能的实现方式,终端设备在根据确定的传输块大小发送上行信号之前,通过接收网络设备发送的DCI,该DCI包括索引指示信息,使得终端设备可以根据索引指示信息直接确定用于传输上行信号的传输块大小,并在传输块大小确定之后,使用Pi/2 BPSK调制模式,在两个连续的上行子载波上,根据所确定的传输块大小发送上行信号,从而实现Pi/2 BPSK调制模式下,使用确定的传输块大小完成上行信号的传输。相应地,网络设备可以对在两个连续的上行子载波上接收到的上行信号使用Pi/2 BPSK调制模式对所述上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
此外,需要说明的是,在获取到索引指示信息指示的索引之后,终端设备还可以根据 索引确定资源单元个数。
示例的,在第一种情况下,以删除408为例,一种可能的方式,支持4种资源单元个数,该4种资源单元个数类型分别为1个资源单元、2个资源单元、3个资源单元及4个资源单元,则索引与资源单元个数之间的关系可以如下表25所示:
表25
结合表25所示,当支持4种资源单元个数类型,且有16个索引及对应的传输块大小时,则可以根据类型个数,将16个索引及对应的传输块大小按照索引大小均匀对应该4种资源单元个数类型,当然,也可以将16个索引及对应的传输块大小按照索引大小非均匀对应该4种资源单元个数类型,从而直接根据索引确定对应的资源单元个数。当然,本申请实施例只是以表25为例进行说明,但并不代表本申请仅局限于此。
一种可能的方式,支持3种资源单元个数类型,该3种资源单元个数类型分别为1个资源单元、2个资源单元及4个资源单元,则索引与资源单元个数之间的关系可以如下表26所示:

表30
结合表30所示,当标准支持3种资源单元个数类型,且有16个索引及对应的传输块大小时,则可以根据资源单元个数类型,将16个索引及对应的传输块大小按照索引大小对应该3种资源单元个数类型,如索引1至4对应1个资源单元,索引5至9对应1个资源单元,索引10至15对应4个资源单元,从而直接根据索引确定对应的资源单元个数。当然,也可以按照其他方式将16个索引及对应的传输块大小与该3种资源单元个数类型对应,在此,本申请实施例只是以表30为例进行说明,但并不代表本申请仅局限于此。
在第三种情况下,以删除144为例,一种可能的方式,支持4种资源单元个数类型,该4种资源单元个数类型分别为1个资源单元、2个资源单元、3个资源单元及4个资源单元,则索引与资源单元个数之间的关系可以如下表31所示:
表31
结合表31所示,当标准支持4种资源单元个数类型,且有16个索引及对应的传输块 大小时,则可以根据9类型个数,将16个索引及对应的传输块大小按照索引大小均匀对应该4种资源单元个数类型,当然,也可以将16个索引及对应的传输块大小按照索引大小非均匀对应该4种资源单元个数类型,从而直接根据索引确定对应的资源单元个数。当然,本申请实施例只是以表31为例进行说明,但并不代表本申请仅局限于此。
一种可能的方式,支持3种资源单元个数类型,该3种资源单元个数类型分别为2个资源单元、3个资源单元及4个资源单元,则索引与资源单元个数之间的关系可以如下表32所示:
表32
结合表32所示,当支持3种资源单元个数类型,且有16个索引及对应的传输块大小时,则可以根据类型个数,将16个索引及对应的传输块大小按照索引大小对应该3种资源单元个数类型,如索引1至4对应2个资源单元,索引5至9对应3个资源单元,索引10至15对应4个资源单元,从而直接根据索引确定对应的资源单元个数。当然,也可以按照其他方式将16个索引及对应的传输块大小与该3种资源单元个数类型对应,在此,本申请实施例只是以表20为例进行说明,但并不代表本申请仅局限于此。

表33
结合表33所示,当支持3种资源单元个数类型,且有16个索引及对应的传输块大小时,则可以根据类型个数,将16个索引及对应的传输块大小按照索引大小对应该3种资源单元个数类型,如索引1至4对应1个资源单元,索引5至9对应2个资源单元,索引10至15对应4个资源单元,从而直接根据索引确定对应的资源单元个数。当然,也可以按照其他方式将16个索引及对应的传输块大小与该3种资源单元个数类型对应,在此,本申请实施例只是以表33为例进行说明,但并不代表本申请仅局限于此。
需要说明的是,由于上述表25-表33中所有索引对应的调制模式全部为Pi/2 BPSK,因此表格中可以不包含调制模式这一列,可以通过在表的名称中或正文中说明等其他方式体现该表格对应的调制模式为Pi/2 BPSK。
同样需要说明的是,上述表25-表33中的索引只是以0开始为例进行说明,当然,也可以从1开始,具体可以根据实际需要进行设置,只要可以根据该索引查找到上述表格中的传输块大小即可。当然,在网络设备、终端设备和芯片以及装置中也可以通过集合的形式体现上面的表格,即将上面表格中的所有索引对应的TBS和资源单元个数组合组成一个集合,通过索引查找该集合中的某一个TBS和资源单元个数组合。
需要说明的是,第三种可实现方式中涉及的方法同样可以适用于QPSK调制模式,其具体过程与Pi/2 BPSK调制模式对应的过程类似,此处不再进行赘述。
需要说明的是,在上述三种可能的实现方式中,在确定用于传输上行信号的传输块大小的过程中,可选的,所涉及的资源单元个数满足预设条件,具体为:当资源单元个数为1时,TBS的最大值为224或256;和/或,当资源单元个数为2时,TBS的最大值为456或504;和/或,当资源单元个数为3时,TBS的最大值为712或808;和/或,当资源单元个数为4时,TBS的最大值为936或1000。
通过上述描述可知,终端设备在接收到网络设备发送的DCI后,可以根据DCI中包括的索引指示信息确定用于传输上行信号的传输块大小,并在传输块大小确定之后,使用Pi/2 BPSK调制模式,在两个连续的上行子载波上,根据所确定的传输块大小发送上行信号。需要说明的是,在本申请实施例,终端设备可以将该上行信号发送给另一个终端设备,从而实现两个终端设备之间的信号传输,也可以将该上行信号发送给网络设备,从而实现终端设备与网络设备之间的信号传输。
当终端设备根据所确定的传输块大小将上行信号发送给网络设备时,网络设备需要在两个连续的上行子载波接收终端设备发送的上行信号,并使用Pi/2 BPSK调制模式对上行信号进行解调,当然,网络设备需要先向终端设备发送该DCI,具体请参见图3所示,图3为本申请实施例提供的一种上行信号的接收方法的示意图,该上行信号的接收方法可以包括:
S301、网线设备向终端设备发送下行控制信息DCI。
S302、网络设备接收终端设备在两个连续的上行子载波发送的上行信号,并使用Pi/2BPSK调制模式对上行信号进行解调。
其中,两个连续的子载波可以是三个连续的子载波中的相邻的两个,两个子载波在三个子载波的位置是小区级统一的,可以是固定的位置,也可以是高层信令/RRC信令配置的位置。
需要说明的是,在本申请实施例中,由于该DCI中包括索引指示信息,因此,网络设备在向终端设备发送下行控制信息DCI之前,需要先确定该索引指示信息,在确定该索引指示信息时,可以通过以下至少三种可能的实现方式确定。
在一种可能的实现方式中,以指示索引指示信息的字段为4比特为例,对应有16个MCS索引,可以通过空闲的5个MCS索引指示Pi/2 BPSK调制模式,网络设备先确定资源单元个数指示信息,并根据资源单元个数指示信息和传输块大小确定TBS索引,再根据TBS索引与第一映射关系确定其对应的MCS索引。在第二种可能的实现方式中,网络设备需要先根据资源单元个数指示信息、载波个数指示信息和/或调制模式信息、传输块大小确定其对应的TBS索引,再根据TBS索引和第二映射关系确定对应的MCS索引。在第三种可能的实现方式中,网络设备可以直接根据传输块大小确定其对应的索引,索引和传输块大小之间具有映射关系。
为了更清楚地说明上述三种可能的实现方式,下面,将以具体的实施例对上述三种可能的实现方式进行详细描述。
在第一种可能的实现方式中,若DCI包括索引指示信息和资源单元个数指示信息,且索引指示信息用于指示MCS索引,则网络设备可以先根据资源单元个数指示信息和传输块大小确定TBS索引,再根据TBS索引和第一映射关系确定MCS索引。
其中,第一映射关系用于指示MCS索引、调制模式及TBS索引的关系。可选的,第一映射关系包括第一部分和第二部分,第一部分用于指示MCS索引、QPSK调制模式、TBS索引的关系,第二部分用于指示MCS索引、Pi/2 BPSK调制模式、TBS索引的关系,进一步地,第二部分包括5个TBS索引,和/或,第二部分的传输块大小的最大值为936或1000。
可选的,在根据第二部分中的TBS索引确定其对应的MCS索引时,第二部分中的5个TBS索引为第一部分中的5个TBS索引。需要说明的是,第一部分中的TBS索引和资源单元个数指示信息对应的传输块大小是预先设置的。
在确定第一部分中的TBS索引时,可以根据资源单元个数指示信息和传输块大小确定TBS索引,当在QPSK调制模式下,资源单元格个数为N时,TBS索引是根据现有标准设置的TBS表格中第K个物理资源块(PRB)对应的列和传输块大小确定的;当在Pi/2 BPSK调制模式下,资源单元格个数为2*N时,TBS索引是根据现有标准设置的TBS表格中第K个物理资源块(PRB)对应的列和传输块大小确定的。其中N和K为正整数。
示例的,请参见上述表19所示,在QPSK调制模式下,资源单元个数N可以为1个或2个,若资源单元个数为1个,则根据TBS表格中第3个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引;若资源单元个数为2个,则根据TBS表格中第6个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引。在Pi/2 BPSK调制模式下,资源单元个数为2个或4个,若资源单元个数为2个,则根据TBS表格中第3个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引;若资源单元个数为4个,则根据TBS表格中第6个PRB对应的列和传输块大小查询上述表19,从而确定资源单元个数和传输块大小对应的TBS索引。
在确定MCS索引时,同样以指示索引指示信息的字段包括4比特为例,则对应16个MCS索引,其中,现有标准规定了0至10共11个MCS索引对应的QPSK调制模式、TBS索引之间的关系,在本申请实施例中,可以将未使用的S个MCS索引设置为Pi/2 BPSK调制模式对应的S个MCS索引。其中S为正整数,S大于2且小于等于5。需要说明的是,若第一部分的MCS索引为16个MCS索引的前11个时(即MCS索引0至10),则未使用的S个MCS索引可以为16个MCS索引的后面S个,即MCS索引11至(11+S-1),当然,若第一部分的MCS索引为16个MCS索引的后11个时(即MCS索引5至15),则未使用的S个MCS索引可以为16个MCS索引的前面S个,即MCS索引(0+5-S)至4。
可选的,在确定第二部分中的TBS索引时,该第二部分中的TBS索引可以为第一部分中的TBS索引0至11中的任一值,但为了分布均匀,可以等间隔取第一部分中的TBS索引作为第二部分中MCS索引对应的TBS索引,当然,也可以非等间隔取第一部分中的TBS索引作为第二部分中MCS索引对应的TBS索引,下面将具体描述如何确定第二部分中的5个MCS索引。
在第一种情况下,当第一部分的MCS索引包括0至10时;则第二部分的MCS索引包括11至(11+S-1),当S=3时,请结合上述表1所示,可以看出,第一部分中MCS索引0至10均对应QPSK模式,且MCS索引0至10与TBS索引0至10一一对应,第二部分中的MCS索引11至13均对应Pi/2 BPSK模式,其中,第一部分中的MCS索引11对应TBS索引1,MCS索引12对应TBS索引5,MCS索引13对应TBS索引9。

此外,第二部分中的MCS索引2也可以对应TBS索引0,MCS索引3对应TBS索引5,MCS索引4对应TBS索引9,请参见上述表6所示。
当然S也可以等于4,当S等于4时,请参见上述表7所示,第一部分中MCS索引0至10均对应QPSK模式,且MCS索引0至10与TBS索引0至10一一对应,第二部分中的MCS索引11至14均对应Pi/2 BPSK模式,其中,第一部分中的MCS索引11对应TBS索引1,MCS索引12对应TBS索引4,MCS索引13对应TBS索引7,MCS索引14对应TBS索引10。
当然,第一部分中的MCS索引11也可以对应TBS索引0,MCS索引12对应TBS索引3,MCS索引13对应TBS索引6,MCS索引14对应TBS索引9,请参见上述表8所示。
此外,第一部分中的MCS索引11也可以对应TBS索引2,MCS索引12对应TBS索引4,MCS索引13对应TBS索引6,MCS索引14对应TBS索引8,请参见上述表9所示。
在第二种情况下,当第一部分的MCS索引包括5至15时,则第二部分的MCS索引包括1至4,请参见上述表10所示,第一部分中MCS索引5至15均对应QPSK模式,且MCS索引5至15与TBS索引0至10一一对应;第二部分中的MCS索引1至4均对应Pi/2 BPSK模式,其中,第二部分中的MCS索引1对应TBS索引1,MCS索引2对应TBS索引4,MCS索引3对应TBS索引7,MCS索引4对应TBS索引10。
当然,第二部分中的MCS索引1也可以对应TBS索引0,MCS索引2对应TBS索引3,MCS索引3对应TBS索引6,MCS索引4对应TBS索引9,请参见上述表11所示。
此外,第二部分中的MCS索引1也可以对应TBS索引2,MCS索引2对应TBS索引4,MCS索引3对应TBS索引6,MCS索引4对应TBS索引8,请参见上述表12所示。
当然S也可以等于5,当S等于5时,请参见上述表13所示,第一部分中MCS索引0至10均对应QPSK模式,且MCS索引0至10与TBS索引0至10一一对应,第二部分中的MCS索引11至15均对应Pi/2 BPSK模式,其中,第二部分中的MCS索引11对应TBS索引1,MCS索引12对应TBS索引3,MCS索引13对应TBS索引5,MCS索引14对应TBS索引7,MCS索引15对应TBS索引9。
当然,第二部分中的MCS索引11也可以对应TBS索引2,MCS索引12对应TBS索引4,MCS索引13对应TBS索引6,MCS索引14对应TBS索引8,MCS索引15对应TBS索引10,请参见上述表14所示。

在第二种情况下,当第一部分的MCS索引包括5至15时,则第二部分的MCS索引包括0至4,请参见上述表16所示,第一部分中MCS索引5至15均对应QPSK模式,且MCS索引5至15与TBS索引0至10一一对应;第二部分中的MCS索引0对应TBS索 引1,MCS索引1对应TBS索引3,MCS索引2对应TBS索引5,MCS索引3对应TBS索引7,MCS索引4对应TBS索引9。

此外,第二部分中的MCS索引0也可以对应TBS索引0,MCS索引1对应TBS索引2,MCS索引2对应TBS索引5,MCS索引3对应TBS索引7,MCS索引4对应TBS索引9,请参见上述表18所示。
在通过上述表1-表18确定第二部分中的TBS索引对应的MCS索引之后,就可以将用于指示MCS索引的索引指示信息和资源单元个数指示信息发送给终端设备。
由此可见,在该种可能的实现方式,网络设备在向终端设备发送DCI之前,若该DCI包括索引指示信息和资源单元个数指示信息,终端设备需要先根据资源单元个数指示信息和传输块大小确定TBS索引,再根据TBS索引和第一映射关系确定对应的MCS索引,之后,再将用于指示MCS索引的索引指示信息和资源单元个数指示信息发送给终端设备,并接收终端设备在两个连续的上行子载波发送的上行信号,使用Pi/2 BPSK调制模式对上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
在第二种可能的实现方式中,网络设备可以先根据资源单元个数指示信息、载波个数指示信息和/或调制模式信息、传输块大小确定其对应的TBS索引,并根据TBS索引和第二映射关系确定对应的MCS索引。
其中,第二映射关系用于指示MCS索引和TBS索引的关系。
在该种可能的实现方式中,由于Pi/2 BPSK调制模式与QPSK调制模式复用同一个TBS表格,因此,在确定TBS索引之前,需要预先获取调制模式,在获取该调制模式时,可以通过载波个数指示信息和/或调制模式信息获取调制模式,在通过载波个数指示信息确定调制模式时,若载波个数指示信息指示载波个数为2个,则确定调制模式为pi/2 BPSK调制模式;若载波个数指示信息指示载波个数为3个或6个,则确定调制模式为QPSK调制模式,当然,若通过调制模式信息确定调制模式,则该调制模式可以为QPSK调制模式或pi/2BPSK调制模式的标识,当然,也可以通过其他方式确定调制模式。
同样以指示索引指示信息的字段包括4比特为例,则对应16个MCS索引,其中,现有标准规定了11个MCS索引对应的QPSK调制模式和TBS索引之间的关系,在确定Pi/2BPSK调制模式下TBS索引对应的MCS索引之前,可以先参见上述表19所示,Pi/2 BPSK调制模式与QPSK调制模式复用同一个TBS表格,可以看出,当调制模式为Pi/2 BPSK调制模式时,其对应的资源单元个数指示信息和传输块大小一一对应,从而可以根据表19确定Pi/2 BPSK调制模式下,资源单元个数指示信息和传输块大小确定对应的TBS索引。在确定TBS索引之后,就可以根据TBS索引和第二映射关系确定其对应的MCS索引。
可选的,在确定TBS索引时,当所述载波个数指示信息和/或调制模式信息指示所述调制模式为QPSK调制模式,所述资源单元个数指示信息指示的资源单元个数为P时,所述TBS索引是根据所述标准已设置的TBS表格中第M个物理资源块(PRB)对应的列和传输块大小确定的。
当所述载波个数指示信息和/或调制模式信息指示所述调制模式为pi/2 BPSK调制模式, 所述资源单元个数指示信息指示的资源单元个数为2*P时,所述TBS索引是根据所述标准已设置的TBS表格中第M个物理资源块(PRB)对应的列和传输块大小确定的。
其中M和P为正整数。
示例的,在QPSK调制模式下,资源单元个数N可以为1个或2个,若资源单元个数为1个,则根据TBS表格中第3个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引;若资源单元个数为2个,则根据TBS表格中第6个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引。在Pi/2 BPSK调制模式下,资源单元个数为2个或4个,若资源单元个数为2个,则根据TBS表格中第3个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引;若资源单元个数为4个,则根据TBS表格中第6个PRB对应的列和传输块大小查询上述表19,从而确定TBS索引,之后,再根据TBS索引和第二映射关系确定对应的MCS索引。可选的,TBS的最大值为936、1000或1032,从而实现两个连续的上行子载波可支持的最大传输块个数为936或1000。
在确定TBS索引之后,就可以根据该TBS索引和第二映射关系确定其对应的MCS索引。同样以指示索引指示信息的字段包括4比特为例,在确定Pi/2 BPSK调制模式下的TBS索引对应的MCS索引时,请参见上述表20所示,可以看出,当调制模式为Pi/2 BPSK调制模式时,其对应的TBS索引与MCS索引也一一对应,从而可以根据表20中的第二映射关系确定Pi/2 BPSK调制模式下,TBS索引对应的MCS索引。
由此可见,在该种可能的实现方式,网络设备在向终端设备发送DCI之前,若该DCI包括载波个数指示信息和/或调制模式信息、索引指示信息、资源单元个数指示信息,网络设备需要先根据资源单元个数指示信息和传输块大小确定TBS索引,且根据载波个数指示信息和/或调制模式信息确定调制模式,再根据TBS索引和第二映射关系确定其对应的MCS索引,之后,再将用于指示MCS索引的指示信息和资源单元个数指示信息发送给终端设备,并接收终端设备在两个连续的上行子载波发送的上行信号,使用Pi/2 BPSK调制模式对上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
在第三种可能的实现方式中,网络设备可以直接根据传输块大小确定其对应的索引指示信息,其中,索引指示信息与传输块大小之间具有映射关系。
其中,DCI包含索引指示信息,索引指示信息与传输块大小之间有映射关系。
以指示索引指示信息的字段为4比特为例,最多能支持16个索引,请结合上述表21所示,表21中第二列中总共有22个输块大小。其中有两个208、两个256、两个328、两个504等,可以删掉两个相等中的任一个,即每一个组相等的两个数中只保留一个,此时还剩下17个用于指示传输块大小的值,还需要再从剩余的17个中删掉一个。示例的,在本申请实施例中,可以根据传输块大小之间的接近程度进行删除。在本申请实施例中,由于144和152比较接近,可以删掉144和152其中一个,或者,由于408和392比较接近,可以删掉408和392其中一个,从而剩下16个传输块大小,该索引指示信息与传输块大小之间的映射关系可以应用于Pi/2 BPSK调制模式。示例的,索引指示信息可以用于指示索引,在确定16个传输块大小对应的16个索引时,可以删除408,并可以参见上述表22所示,可以看出,在17个值中删除408之后,剩余16个传输块大小,由于传输块大小与索引一一对应,则网络设备可以直接根据用于传输上行信号的传输块大小确定索引。
当然,在确定16个传输块大小对应的16个索引时,也可以删除152,请参见上述表 23所示,可以看出,在17个值中删除152之后,剩余16个传输块大小,由于索引与传输块大小一一对应,则网络设备可以直接根据用于传输上行信号的传输块大小确定索引指示信息。
此外,在确定16个传输块大小对应的16个索引时,还可以删除144,请参见上述表24所示,可以看出,在17个值中删除144之后,剩余16个传输块大小,由于索引与传输块大小一一对应,则网络设备可以直接根据用于传输上行信号的传输块大小确定索引指示信息。
由此可见,在该种可能的实现方式,网络设备在向终端设备发送DCI之前,若该DCI包括索引指示信息,则网络设备直接可以根据索引指示信息与传输块大小之间的关系确定索引指示信息,之后,再将索引指示信息发送给终端设备,并接收终端设备在两个连续的上行子载波发送的上行信号,使用Pi/2 BPSK调制模式对上行信号进行解调,从而能够基于Pi/2 BPSK调制模式完成上行信号的接收。
需要说明的是,第三种可实现方式中涉及的方法同样可以适用于QPSK调制模式,其具体过程与Pi/2 BPSK调制模式对应的过程类似,此处不再进行赘述。
在上述三种可能的实现方式中,在确定索引的过程中,可选的,所涉及的资源单元个数满足预设条件,具体为:当资源单元个数为1时,TBS的最大值为224或256;和/或,当资源单元个数为2时,TBS的最大值为456或504;和/或,当资源单元个数为3时,TBS的最大值为712或808;和/或,当资源单元个数为4时,TBS的最大值为936或1000。
需要说明的是,网络设备在通过上述三种可能的实现方式确定MCS索引或索引时,其采用的方式与终端设备通过三种可能的实现方式确定用于传输上行信号的传输块大小所采用的方式匹配。例如,网络设备在确定DCI中包括的MCS索引时,若采用第一种可能的实现方式,则终端设备接收到包括该MCS索引的DCI后,相应的,也会采用终端设备的第一种可能的实现方式根据DCI确定用于传输上行信号的传输块大小。当然,若网络设备在确定DCI中包括的MCS索引时,若采用第二种可能的实现方式,则终端设备接收到包括该MCS索引的DCI后,相应的,也会采用终端设备的第二种可能的实现方式根据DCI确定用于传输上行信号的传输块大小。
