此时,通过在调制阶数越低时,允许的传输块的最大重复次数越大,进而可以满足一些对传输块的误块率有较高要求的业务。例如,对于高可靠低延时的URLLC业务,为了满足高可靠性,一般会选择调制编码方式索引越低,调制阶数更低阶的编码方式,而在现有技术中,在调制编码方式索引越低时,传输块的重复次数一般比较少或者是在每种传输块大小一样的情况下,无差别的对应***中规定的重复次数。而在本申请中,调制编码方式索引越低,调制阶数低时允许传输块的重复次数更多,与相同的调制编码方式对应的重复次数是非等间隔的,特别地,越低阶的调制编码方式对应了更多的重复次数,给低阶MCS更多种类的重复次数也可以加细低阶的MCS,从而给URLLC业务确定一个更加合适的MCS,来满足高可靠低延时的URLLC业务对可靠性的要求。

图4示出了本申请的无线装置的示意性框图。
图5示出了本申请提供的通信装置的示意性框图。
下面将结合附图,对本申请中的技术方案进行描述。
图1是使用本申请的一种无线通信的方法和设备的通信***的示意图。如图1所示,所述通信***100包括网络设备102,网络设备102可包括多个天线例如,天线104、106、 108、110、112和114。另外,网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目标终端设备通信。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工(Frequency Division Duplex,FDD)***中,例如,前向链路118可与反向链路120使用不同的频带,前向链路124可与反向链路126使用不同的频带。
再例如,在时分双工(Time Division Duplex,TDD)***和全双工(Full Duplex,FD)***中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如,可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中,网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外,与网络设备通过单个天线向它所有的终端设备发送信号的方式相比,在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时,相邻小区中的移动设备会受到较少的干扰。
在给定时间,网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目标数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。
现有的传输块的调制编码方式(Modulation Coding Scheme,MCS)是接收端接收到的传输块的误块率不超过10
-1的最高调制编码方式。而一些对传输块的误块率有较高要求的业务,例如,5G中定义了高可靠低延时的URLLC业务,端到端时延要求小于1ms,目标误块率BLER不超过10
-4或者10
-5。该高可靠低延时的URLLC业务未来主要应用于自动驾驶,远程控制,工业控制,触觉互联,VR等领域,因此必须解决提供一种通信方法来解决一些对传输块的误块率有较高要求的业务。
为了满足对传输块的误块率有较高要求的业务,一般会在现有的调制编码方式表格的基础上添加在增加一个新调制编码方式的表格,该新调制编码方式的表格中包括更低的编码速率。但是新旧表格的选择带来了更多的信令开销。
在现有技术中,传输块大小(Transport block size,TBS)与携带***信息的物理下行控制信道(Physical Downlink Shared Channel,PDSCH)的重复次数进行了绑定,并且由一个新的索引同时指示传输块大小和重复次数。这种绑定规则是无差别的均匀分布,即一种传输块大小分别对应了***中允许的所有PDSCH的重复次数。如表1所示,表1示出 了传输块大小与携带***信息的物理下行控制信道的重复次数的绑定关系,该绑定关系由一个新的索引同时指示。
表1 传输块大小与携带***信息的物理下行控制信道的重复次数的绑定关系
索引 | 物理下行控制信道的重复次数 | 传输块大小 |
0 | N/A | N/A |
1 | 4 | 208 |
2 | 8 | 208 |
3 | 16 | 208 |
4 | 4 | 256 |
5 | 8 | 256 |
6 | 16 | 256 |
7 | 4 | 328 |
8 | 8 | 328 |
9 | 16 | 328 |
10 | 4 | 504 |
11 | 8 | 504 |
12 | 16 | 504 |
13 | 4 | 712 |
14 | 8 | 712 |
15 | 16 | 712 |
16 | 4 | 936 |
17 | 8 | 936 |
18 | 16 | 936 |
19-31 | Reserved | Reserved |
在表1中,可以看出在传输块大小一样时,分别对应了4、8和16三种物理下行控制信道的重复次数,每种传输块大小分别对应了***中允许的所有PDSCH的重复次数。

为了更好地理解本申请,以下将结合图2-图5,以与图1所示的***相同或相似的***为例对本申请进行说明。
图2是本申请的一种通信方法200的示意性流程图。如图2所示,该方法200包括以下内容。
在210中,网络设备确定第一索引,该第一索引用于指示第一调制编码方式信息和传输块的重复次数,其中,该第一调制编码方式信息和该传输块的重复次数对应于第一可靠性需求。
具体而言,该传输块的重复次数为该传输块总的传输次数,如一个传输块的重复次数为4,那么该传输块总共传输了4次。

在230中,该无线装置接收该网络设备发送的该第一索引。
在240中,该无线装置根据该第一索引指示的第一调制编码方式信息解调该传输块。
因此,在本申请实施例中,通过该第一调制编码方式信息和该传输块的重复次数来满足该第一可靠性需求,由于该第一索引不仅可以指示该第一调制编码方式信息,还可以指示该传输块的重复次数,因此不需要另外的信令携带该传输块的重复次数,节省了信令开销。

可选地,如该第一可靠性需求可以是误块率(Block-Error Rate,BLER),也可以为误比特率(Bit-Error Rate,BER)。
应理解,本申请所提出的误块率和误比特率仅用作示例,并不对第一可靠性需求构成任何限定,该第一可靠性需求还可以是其他可靠性需求。

应理解,在表2和表3中,仅示出了调制编码方式信息包括的调制阶数,没有示出其余调制编码方式信息包括的参数,如码率和传输块大小的索引,上述表2和表3仅用作示例,不对调制编码方式信息构成任何限定。
此时,通过建立调制编码方式索引与传输块重复次数的关系,可以兼容不同的可靠性需求。
在本申请中,该第一索引、该第一调制编码方式信息和该传输块的重复次数之间的对应关系不局限于该第一索引、该第一调制编码方式信息和该传输块的重复次数必须在一个表格中,因此,使得第一索引、该第一调制编码方式信息和该传输块的重复次数之间的对应关系更加灵活。
应理解,该调制编码方式索引与该传输块的重复次数还可以有其他对应方式,如式(1)所示:
R=f(x) (1)
其中,x为第一编码方式索引,R为该传输块的重复次数,通过该第一编码方式索引x和式(1)可以确定该传输块的重复次数。
还应理解,式(1)仅用作示例,在针对不同的可靠性需求时,该调制编码方式索引与该传输块的重复次数的函数关系可能不相同。
还应理解,该调制编码方式索引与该传输块的重复次数之间的对应关系还可以有其他的形式,本申请对此不进行限定。
可选地,该第一表格包括至少两组信息,该至少两组信息中的每组信息包括索引、调制编码方式信息和传输块的重复次数,该每组信息中包含的该传输块的重复次数的数量为一个,该至少两组信息所包含的传输块的重复次数不同,当该第一表格中的第二调制编码方式阶数小于该第一表格中的第三调制编码方式阶数时,该第二调制编码方式阶数对应的传输块的重复次数大于或等于该第三调制编码方式阶数对应的传输块的重复次数。
具体而言,如上表2所示,该第一表格包括至少两组信息,该至少两组信息中的每组信息包括索引、调制编码方式信息和传输块的重复次数。该至少两组信息所包含的传输块的重复次数不同。当该第一表格中的该第二索引7小于该第三索引8时,该第二索引对应的传输块的重复次数8大于该第三索引对应的传输块的重复次数4;当该第一表格中的该第二索引6小于该第三索引7时,该第二索引对应的传输块的重复次数8等于该第三索引对应的传输块的重复次数8。
此时,通过在调制编码方式索引越低时,允许的传输块的重复次数越多,进而可以满足一些对传输块的误块率有较高要求的业务。例如,对于高可靠低延时的URLLC业务,为了满足高可靠性,一般会选择调制编码方式索引越低,调制阶数更低阶的编码方式,而在现有技术中,在调制编码方式索引越低时,传输块的重复次数一般比较少或者是在每种 传输块大小一样的情况下,无差别的对应***中规定的重复次数。而在本申请中,调制编码方式索引越低,调制阶数低时允许传输块的重复次数更多,与相同的调制编码方式对应的重复次数是非等间隔的,特别地,越低阶的调制编码方式对应了更多的重复次数,给低阶MCS更多种类的重复次数也可以加细低阶的MCS,从而给URLLC业务确定一个更加合适的MCS,来满足高可靠低延时的URLLC业务对可靠性的要求。
应理解,该每组调制编码方式信息所包含的内容类别是一致的,例如都包括调制阶数、编码速率和重复次数。但是两者具体的调制阶数和编码速率不完全相同,例如该第一组调制编码方式信息为:调制阶数为正交相移键控(Quadrature Phase Shift Keying,QPSK),编码速率为0.2;该第二组调制编码方式信息为:调制阶数为QPSK,编码速率为0.3。该第一组调制编码方式信息和该第二组调制编码方式信息有相同的调制阶数但不同的编码速率。
可选地,网络设备根据信道状态信息和可靠性需求从该第一表格中确定该第一索引。
具体而言,信道状态信息包括秩指示(Rank Indicator,RI),预编码矩阵指示(Precoding-Matrix Indicator,PMI)和信道质量指示(Channel Quality Indicator,CQI)。为了给传输块选择一个合适的调制方式和信道编码速率,网络设备需要知道无线信道质量的信息,根据不同的信道质量信息选择不同的调制编码方式。对于下行链路,网络设备会以恒定功率发射下行参考信号,无线装置根据下行参考信号做下行链路信道质量的估计。现有通信协议将信道质量量化成为0-15共16个等级,并将该16个等级定义为信道质量指示(CQI),从小到大分别对应着信道质量从坏到好。无线装置将下行链路信道质量的估计结果映射为CQI并反馈给网络设备。对于上行链路,无线装置会以恒定功率发射上行参考信号,网络设备根据上行参考信号做上行链路信道质量的估计,从而得到上行链路的信道状态信息。
网络设备在获取了上行链路或者下行链路的信道状态后,根据该第一可靠性需求选取合适的传输块的调制编码方式和该传输块的重复次数。
应理解,无线装置反馈的CQI所对应的调制编码方式仅作为网络设备调度的参考,实际中网络设备会考虑一些除了信道状态之外的其他信息用于调度。
可选地,在210之前,该方法200还包括:网络设备接收无线装置发送的信道状态信息。
可选地,该第二表格包括至少两组信息,该至少两组信息中的每组信息包括索引、和调制编码方式信息,该第三表格包括至少两组信息,该至少两组信息中的每组信息包括索引、和传输块的重复次数,该每组信息中包含的该传输块的重复次数的数量为一个;该至少两组信息所包含的传输块重复次数不同;当该第二表格中的第二调制编码方式阶数小于该第二表格中的第三调制编码方式阶数时,该第二调制编码方式阶数对应的该第三表格中的传输块的重复次数大于或等于该第三调制编码方式阶数对应的该第三表格中的传输块的重复次数。
具体而言,如上表3所示,该第二表格包括至少两组信息,该至少两组信息中的每组信息包括索引和调制编码方式信息。如上表4所示,该第三表格包括该第二索引7小于该第三索引8时,该第二索引对应的传输块的重复次数8大于该第三索引对应的传输块的重复次数4;当该第三表格中的该第二索引6小于该第三索引7时,该第二索引对应的传输 块的重复次数8等于该第三索引对应的传输块的重复次数8。
应理解,该网络设备可以是根据信道状态信息和可靠性需求从该第二表格和该第三表格中确定第一索引。
应理解,在本申请中,该每组信息中包含的该传输块的重复次数的数量为一个,即该重复快的重复次数为一个,如表2、表3和表4中每行信息中的所示的重复次数为一种,如一行信息的该传输块有重复8次的,另一行信息的该传输块有重复4次的,但不会同时出现一行信息的该传输块可以重复8次也可以重复4次。
可选地,该第一表格属于第一信息集合;该第一信息集合包括至少两组信息,该至少两组信息中的每组信息包括调制编码方式信息和传输块的重复次数,该每组信息中的该传输块的重复次数的数量为至少一个;
该至少两组信息所包含的传输块的最大重复次数不同;
该第一信息集合中的第一调制编码方式信息包括的第一调制编码方式阶数小于该第一信息集合中的第二调制编码方式信息包括的第二调制编码方式阶数时,该第一调制编码方式信息对应的传输块的最大重复次数大于或等于该第二调制编码方式信息对应的传输块的最大重复次数,
该第一表格包括至少一个索引,以及与该至少一个索引对应的调制编码方式信息和传输块的一个重复次数。
具体而言,如表5所示,表5示出了该第一信息集合的一种表现形式,该第一信息集合还可以有其他的表示方法。在表5中,该每组信息包括调制编码方式信息和传输块的重复次数,该传输块的重复次数为至少一个重复次数,如表5中,每组调制阶数和TBS索引对应的传输块的重复次数可以是1、2、4或8,也可以是1、2或4。在表5中,该至少两组信息所包含的传输块的最大重复次数不同,该第一信息集合中的第一调制编码方式信息包括的第一调制编码方式阶数小于该第一信息集合中的第二调制编码方式信息包括的第二调制编码方式阶数时,该第一调制编码方式信息对应的传输块的最大重复次数大于或等于该第二调制编码方式信息对应的传输块的最大重复次数。
表5 第一信息集合
此时,通过在调制阶数越低时,允许的传输块的最大重复次数越大,进而可以满足一些对传输块的误块率有较高要求的业务。例如,对于高可靠低延时的URLLC业务,为了满足高可靠性,一般会选择调制编码方式索引越低,调制阶数更低阶的编码方式,而在现有技术中,在调制编码方式索引越低时,传输块的重复次数一般比较少或者是在每种传输块大小一样的情况下,无差别的对应***中规定的重复次数。而在本申请中,调制编码方式索引越低,调制阶数低时允许传输块的重复次数更多,与相同的调制编码方式对应的重复次数是非等间隔的,特别地,越低阶的调制编码方式对应了更多的重复次数,给低阶MCS更多种类的重复次数也可以加细低阶的MCS,从而给URLLC业务确定一个更加合适的MCS,来满足高可靠低延时的URLLC业务对可靠性的要求。
可选地,该网络设备根据业务类型、无线装置类型等信息从第一信息集合中确定该第一表格。
具体而言,该网络设备根据业务类型、无线装置类型从第一信息集合中确定出至少一组信息,并且该至少一组信息会对应一个索引,如表1所示,当该业务类型为URLLC业务时,该网络设备从该第一信息集合中选择出适合URLLC业务的多组信息,并且该每组信息对应一个索引。
可选地,该网络设备根据业务类型、无线装置类型从第一信息集合中确定该第一表格,一般先由高层(如无线资源控制(Radio Resource Control,RRC)信令或者媒体接入控制层层(Media Access Control,MAC)信令等,本申请并不限定该信令的形式或种类)从该 第一信息集合中选取某些项组成该第一表格,网络设备在从该第一表格中确定一个合适的调制编码方式。如表6所示,表6为从第一信息集合中确定的该第一表格。
表6 MCS索引、调制阶数、TBS索引与传输块重复次数的关系表
应理解,该第一信息集合中的每组信息还可以包括该组信息的索引。但该第一信息结合中的索引与第一表格中的索引不同,该第一表格中的索引并不是按照该第一信息集合中 的每组信息对应的索引。
可选地,该第一信息集合中的第一调制编码方式信息包括的第一调制编码方式阶数小于该第一信息集合中的第二调制编码方式信息包括的第二调制编码方式阶数时,该第二调制编码方式信息对应的传输块的重复次数为该第一调制编码方式信息对应的传输块的重复次数的子集。
具体而言,如表7所示,表7示出了该第一信息集合中的第一调制编码方式信息包括的第一调制编码方式阶数小于该第一信息集合中的第二调制编码方式信息包括的第二调制编码方式阶数时,该第二调制编码方式信息对应的传输块的重复次数为该第一调制编码方式信息对应的传输块的重复次数的子集,如调制阶数为2时,重复次数为1、2、4或8,当调制阶数为4时,重复次数为1、2或4。
表7 第一信息集合
可选地,当该第一调制编码方式信息包括的调制阶数小于该第二调制编码方式信息包括的调制阶数时,该第一调制编码方式信息对应的传输块的最大重复次数大于该第二调制编码方式信息对应的传输块的最大重复次数。
表8 第一信息集合
具体而言,如表8所示,当调制阶数为2时,该调制阶数对应的传输块重复次数为1、2、4或8,最大重复次数为8,当调制阶数为4时,该调制阶数对应的传输块重复次数为1、2或4,最大重复次数为4,即当该第一调制编码方式信息包括的调制阶数小于该第二调制编码方式信息包括的调制阶数时,该第一调制编码方式信息对应的传输块的最大重复次数大于该第二调制编码方式信息对应的传输块的最大重复次数。
可选地,该第一调制编码方式阶数小于第二调制编码方式阶数包括:
该第一调制阶数小于该第二调制阶数;或
该第一调制阶数和该第二调制阶数相同,且第一码率小于第二码率;或
该第一调制编码方式阶数对应的索引小于该第二调制编码方式阶数对应的索引;
其中,该第一调制编码方式信息包括该第一调制阶数和该第一码率,该第二调制编码方式信息包括该第二调制阶数和该第二码率。
具体而言,如何确定调制编码方式阶数小有三种情况。第一,当调制阶数越小时,可以认为调制编码方式阶数越小;第二当调制阶数相同,且码率越小时可以认为调制编码方式阶数越小;第三,当调制编码方式阶数对应的索引越小时可以认为调制编码方式阶数越小。
可选地,该第一表格属于第一信息集合,该第一信息集合包括至少两组信息,该至少两组信息中的每组信息包括调制编码方式信息和传输块的重复次数,该传输块的重复次数为至少一个重复次数,该至少两组信息所包含的传输块的重复次数不完全相同,该第一表格包括至少一个索引,以及与该至少一个索引对应的调制编码方式信息和传输块的一个重复次数。
表9 第一信息集合
具体而言,如表9所示,在表9中,该每组信息包括调制编码方式信息和传输块的重复次数,该传输块的重复次数为至少一个重复次数,如表9中,每组调制阶数和TBS索引对应的传输块的重复次数可以是1、2、4或8,也可以是1、2或4,也可以是1、2或8等。
在240中,该无线装置根据该第一索引指示的第一调制编码方式信息解调该传输块。
具体而言,该网络设备向该无线装置发送了该第一索引后,会向该无线装置发送传输块,该传输块承载了数据信息。该无线装置接收该传输块,并且根据第一索引指示的第一调制编码方式信息解调该传输块。
根据该调制编码方式索引指示的该传输块的第一调制编码方式信息可以有两种解读方式。
其一,该实际调制编码方式就是该第一调制编码方式信息包括的调制编码方式,其中的编码速率是重复发送的传输块中每一个传输块的编码速率;同时该调制编码方式还对应了一种重复次数。
例如该第一调制编码方式信息包括的调制编码方式参数为:QPSK,码率0.4,repetition次数为4次,则无线装置解读到该传输块传输4次,四个传输块中每一个传输块的码率为0.4。
其二,该实际调制编码方式是该第一调制编码方式信息确定的一种新的调制编码方 式,指示的是重复后所有传输块的调制编码方式。该重复后所有传输块的码率为该第一调制编码方式信息包括的码率除以该传输块的重复次数。
例如该当前传输块的调制编码方式为:调制方式为QPSK,码率为0.4,当前传输块重复4次,由于所用资源变为原来的4倍,那么码率变为原来的1/4。即该4个传输块的实际调制编码方式为:调制方式QPSK,码率为0.1。
