本申请实施例可以通过动态发送第一信令和第二信令来传输DCI,以提高系统的灵活性。下面对本申请实施例的方案进行详细描述。
图2是本申请实施例提供的一种传输下行控制信息的方法200的示意性流程图。该方法200可选地可以应用于图1所示的系统,但并不限于此。如图2所示,该方法200包括以下至少部分内容。
在步骤210中,终端设备接收第一信令,以及接收第二信令,所述第一信令用于指示所述DCI中所支持调度的传输块的最大数量,所述第二信令用于指示所述终端设备反馈信道质量信息所支持的信道秩和/或传输层数的最大取值。其中,第一信令可以为高层信令,第二信令可以为高层信令。所支持调度的传输块的最大数量可以为1或2,信道秩和/或传输层数的最大取值可以为大于或等于1且小于或等于8的正整数。
在步骤220中,终端设备根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,接收DCI。
基于以上方案,终端设备依据第一信令指示的下行控制信息中所支持调度的传输块的最大数量,以及第二信令指示的所述终端设备反馈信道质量信息所支持的信道秩和/或传输层数的最大取值,来进行下行控制信息的接收,使得下行控制信息动态指示的传输方案(例如,MIMO传输方案)依赖于终端设备反馈的信道状态信息以及下行控制信息的设置,避免半静态配置传输方案,因此可以在下行控制信息设置方面来灵活地确定传输方案,提高通信系统的灵活性。
可选地,在步骤220中,当信道秩和/或传输层数的最大取值小于或等于第一阈值,所支持调度的传输块的最大数量小于或等于第二阈值时,终端设备接收DCI。当信道秩和/或传输层数的最大取值大于第一阈值,所支持调度的传输块的最大数量大于第二阈值时,终端设备接收DCI。
可选地,在步骤220中,终端设备可以不受限于第一信令和第二信令所指示的信息,都会去接收DCI。
下面对终端设备接收DCI的方式进行描述。
可选地,在步骤220中,终端设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中包括的信息域的情况,该信息域的情况例如可以是信息域的组数、信息域的类型和/或信息域的其他信息等。进一步地,终端设备可以根据信息域的情况来接收DCI。
以信息域的情况为信息域的组数和/或信息域的类型为例,终端设备可以根据信息域的组数和/或信息域的类型,确定DCI的比特位长度,从而来正确接收DCI。
需要说明的是,信息域的类型可以根据信息域所指示的信息来进行划分。
DCI可用于调度共享信道传输,为方便描述,将第一信令中可支持调度的传输块的最大数量称为第一数量,将在传输共享信道使用的传输层数等于信道秩和/或传输层数的最大取值的情况下,共享信道 包括的传输块的数量称为第二数量。
具体地,终端设备可以确定下行控制信息中包括的信息域的组数等于第一数量。
当第一数量大于第二数量时,该第一数量组信息域包括第二数量组信息域和其他组信息域。该第二数量组信息域的类型为第一类型,第一类型信息域用于指示传输块的调度信息。其他组信息域的类型为第二类型,该第二类型信息域用于指示第一信息,该第一信息与传输块调度信息不同,即第二类型信息域用于指示与传输块的调度信息无关的信息。
也就是说,该第二数量组信息域中的每组信息域用于指示一个传输块的调度信息,其他组信息域中的每组信息域用于指示与传输块的调度信息无关的信息。
该第一信息可以包括以下信息中的至少一种:业务等级、编码块组(coding block group,CBG)信息及其相关信息、带宽部分(bandwidth part,BWP)信息及其相关信息等。
应理解,其他组信息域的组数可以为第一数量与第二数量的差值,也可以小于第一数量与第二数量的差值。
本申请实施例提供的技术方案中,当第一信令所指示的传输块的最大数量大于第二信令所指示的传输块的最大数量时,可以将DCI中的第二数量组信息域用于指示传输块的调度信息,将其他组信息域用于指示与传输块调度无关的其他信息,这样可以在不增加信令的情况下传输其他信息,能够节省信令开销,达到重用DCI信息域的目的。
此外,本申请实施例提供的技术方案,在第一信令和第二信令不匹配的情况下,即第一信令和第二信令所指示的传输块的最大数量不一致的情况下,能够确定一种DCI的传输方案,使得终端设备和网络设备能够对DCI包括的信息域的组数和信息域的类型具有一致的认识,从而能够提高系统的可靠性以及传输数据的效率。
当第一数量等于第二数量时,DCI中信息域的组数等于第一数量,该第一数量组信息域的类型为第一类型,该第一数量组信息域中的每一组信息域分别用于指示一个传输块的调度信息。终端设备可以根据DCI中信息域的组数和/或信息域的类型,确定该DCI的比特位长度,从而来正确接收DCI。
当第一数量小于第二数量时,DCI中信息域的组数等于第一数量。该第一数量组信息域的类型为第一类型,该第一数量组信息域中的每一组信息域分别用于指示一个传输块的调度信息。终端设备可以根据DCI中信息域的组数和/或信息域的类型,确定该DCI的比特位长度,从而来正确接收DCI。
此外,终端设备还接收网络设备发送的第一物理下行共享信道(physical downlink shared channel,PDSCH),并可以根据DCI中的信息域的组数和/或信息域的类型,向网络设备发送第一PDSCH对应的应答(acknowledgment,ACK)或否定应答(negative acknowledgement,NACK)反馈信息。该ACK/NACK反馈信息的比特数目等于第二数量与第一数量中的最小值,即该ACK/NACK反馈信息的比特数目等于DCI中第一类型信息域的组数,也就是说,该ACK/NACK反馈信息的比特数目等于DCI中用于指示传输块调度信息的信息域的组数。
例如,当第一数量大于第二数量时,ACK/NACK反馈信息的比特数目等于第二数量。以第一数量为2,第二数量为1进行详细描述。DCI中包括2组信息域,其中一组信息域用于指示一个传输块的调度信息,另一组信息域用于指示与传输块的调度信息无关的第一信息。终端设备可以根据该DCI中包括的信息域的组数和/或信息域的类型,向网络设备发送第一PDSCH对应的ACK/NACK反馈信息,该ACK/NACK反馈信息的比特数目等于DCI包括的指示传输块的调度信息的信息域的组数,即1个比特。
可选地,在步骤220中,终端设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定所述DCI中包括的信息域的组数和/或信息域的类型。进而终端设备可以根据该信息域的组数和/或信息域的类型,确定DCI的比特位长度来接收DCI。
可选地,终端设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中实际可调度的传输块的最大数量,并根据DCI中实际可调度的传输块的最大数量,接收DCI。
本申请实施例对终端设备确定DCI中实际可调度的传输块的最大数量的方式不做具体限定。
作为一种示例,终端设备可以直接根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中实际可调度的传输块的最大数量。
作为另一种示例,终端设备可以根据表1所示的传输层数与码字的对应关系,确定当传输共享信道使用的传输层数等于信道秩和/或传输层数的最大取值时,共享信道所包含的传输块的数量。进一步终端设备可以根据共享信道所包含的传输块的数量和所支持调度的传输块的最大取值,确定DCI中实际可调度的传输块的最大数量。
下面对终端设备确定DCI中实际可调度的传输块的最大数量进行详细描述。
为方便描述,将DCI中实际可调度的传输块的最大数量称为第三数量,将在传输共享信道使用的传输层数等于信道秩和/或传输层数的最大取值的情况下,共享信道包括的传输块的数量称为第二数量, 将第一信令中可支持调度的传输块的最大数量称为第一数量。以NR系统为例,第一数量、第二数量、第三数量可以分别取值为1或2。
可选地,终端设备可以确定第三数量为第二数量和第一数量中的最大值。
例如,当第一数量为2,第二数量为1,或者第一数量为1,第二数量为2,或者第一数量为2,第二数量为2时,终端设备可以确定第三数量为2。当第三数量为2时,表示网络设备向终端设备发送的DCI中包括2组信息域,且2组信息域中的每组信息域分别用于指示一个传输块调度信息。
又例如,当第一数量为1,第二数量为1时,终端设备可以确定第三数量为1。当第三数量为1时,表示网络设备向终端设备发送的DCI中只有1组信息域,该一组信息域用于指示一个传输块调度信息。
可选地,终端设备也可以确定第三数量为第二数量和第一数量中的最小值。
例如,当第一数量为2,第二数量为1,或者第一数量为1,第二数量为2,或者第一数量为1,第二数量为1时,终端设备可以确定第三数量为1。当第三数量为1时,表示网络设备向终端设备发送的DCI中只有1组信息域,该一组信息域用于指示一个传输块调度信息。
又例如,当第一数量2,第二数量为2时,终端设备可以确定第三数量为2。当第三数量为2时,表示网络设备向终端设备发送的DCI中包括2组信息域,且2组信息域中的每组信息域分别用于指示一个传输块调度信息。
此外,终端设备也可以确定第三数量为第二数量和第一数量的平均值。
本申请实施例提供的技术方案,可以在第一信令和第二信令不匹配的情况下,即第一信令和第二信令所指示的传输块的最大数量不一致的情况下,提供一种通过确定DCI中实际可调度的传输块的最大数量来发送DCI的方式,能够实现终端设备与网络设备之间的良好通信。
当终端设备确定DCI中实际可调度的传输块的最大数量为第三数量时,可以根据该第三数量接收网络设备发送的DCI。进一步地,终端设备可以接收网络设备发送的第二PDSCH,并根据DCI中的信息域的组数和/或信息域的类型,向网络设备发送第二PDSCH对应的ACK/NACK反馈消息,该ACK/NACK反馈信息的比特数目等于第三数量,即该ACK/NACK反馈信息的比特数目等于DCI中实际可调度的传输块的数量,也可以说该ACK/NACK反馈信息的比特数目等于DCI中用于指示传输块调度信息的信息域的组数。
可选地,在步骤220中,终端设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,不接收DCI。
例如,当信道秩和/或传输层数的最大取值小于或等于第一阈值,且所支持调度的传输块的最大数量大于第二阈值时,终端设备接收DCI。或者,当信道秩和/或传输层数的最大取值大于第一阈值,且所支持调度的传输块的最大数量小于或等于第二阈值时,终端设备不接收DCI。
可选地,在步骤220中,终端设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,接收DCI。
例如,当信道秩和/或传输层数的最大取值小于或等于第一阈值,且所支持调度的传输块的最大数量小于或等于第二阈值时,终端设备接收DCI。或者,当信道秩和/或传输层数的最大取值大于或等于第一阈值,且所支持调度的传输块的最大数量大于或等于第二阈值时,终端设备接收DCI。
其中,DCI可用于调度共享信道传输,当传输共享信道使用的传输层数等于第一阈值时,共享信道包括的传输块的数量等于第二阈值。
可选地,当第一阈值为4时,第二阈值为1;和/或,当第一阈值为8时,第二阈值为2。
以表1为例,当信道秩和/或传输层数的最大取值小于或等于4,且所支持调度的传输块的最大数量为1时,终端设备接收DCI。或者,当信道秩和/或传输层数的最大取值小于或等于8,且所支持调度的传输块的最大数量等于1时,终端设备接收DCI。或者,当信道秩和/或传输层数的最大取值大于4且小于或等于8,且所支持调度的传输块的最大数量等于2时,终端设备接收DCI。
当信道秩和/或传输层数的最大取值小于或等于4,且所支持调度的传输块的最大数量为2时,或者当信道秩和/或传输层数的最大取值大于4且小于或等于8,且所支持调度传输块的最大数量为1时,终端设备可以不接收网络设备发送的DCI。
可选地,当信道秩和/或传输层数的最大取值小于5,且所支持调度的传输块的最大数量为2时,终端设备接收DCI。或者,当信道秩和/或传输层数的最大取值小于或等于8,且所支持调度的传输块的最大数量等于1时,终端设备接收DCI。或者,当信道秩和/或传输层数的最大取值大于或等于5且小于或等于8,且所支持调度的传输块的最大数量等于2时,终端设备接收DCI。
当信道秩和/或传输层数的最大取值小于5,且所支持调度的传输块的最大数量为1时,或者当信道秩和/或传输层数的最大取值大于或等于5且小于或等于8,且所支持调度传输块的最大数量为1时,终端设备可以不接收网络设备发送的DCI。
可选地,当所述信道秩和/或传输层数的最大取值小于或等于第一阈值时,终端设备不期待所支持调度的传输块的最大数量大于或等于第二阈值。或者,当所支持调度的传输块的最大数量大于或等于第二阈值时,终端设备不期待信道秩和/或传输层数的最大取值小于或等于第一阈值。或者,当信道秩和/或传输层数的最大取值大于或等于第一阈值时,终端设备不期待所支持调度的传输块的最大数量小于或等于第二阈值。或者,当所支持调度的传输块的最大数量小于或等于第二阈值时,终端设备不期待信道秩和/或传输层数的最大取值大于或等于第一阈值。
以第一阈值为4,第二阈值为1为例进行说明。为方便描述,假设信道秩和/或传输层数的最大取值为第一值,所支持调度的传输块的最大数量为第二值,当第一值小于或等于4时,终端设备不期待第二值大于1。同理,当第二值小于或等于1时,终端设备不期待第二值大于4。
即,当第一值小于或等于4,且第二值为2时,或者当第一值大于4且小于或等于8,且第二值为1时,终端设备可以确定该第一信令和第二信令为错误配置,终端设备可以不接收网络设备发送的DCI。或者,终端设备在确定第一信令和第二信令为错误配置时,可以不执行DCI所调度的数据传输。
当第一值小于或等于4,且第二值为1时,或者当第一值大于4且小于或等于8,且第二值为2时,终端设备可以确定该第一信令和第二信令为正确配置。终端设备可以接收网络设备发送的DCI,执行该DCI所指示的数据调度。
可选地,终端设备可以根据表1所示的传输层数与码字的对应关系,确定当共享信道使用的传输层数等于信道秩和/或传输层数的最大取值时,共享信道中包括的传输块的数量。进一步再根据共享信道中包括的传输块的数量和所支持调度的传输块的最大数量,确定是否接收DCI。
具体地,当共享信道中包括的传输块的数量与所支持调度的传输块的最大数量相等时,终端设备接收DCI。当共享信道中包括的传输块的数量与所支持调度的传输块的最大数量不相等时,终端设备可以不接收DCI。
当信道秩和/或传输层数的最大取值小于或等于第一阈值,且所支持调度的传输块的最大数量小于或等于第二阈值时,或者,当信道秩和/或传输层数的最大取值大于或等于第一阈值,且所支持调度的传输块的最大数量大于或等于第二阈值时,终端设备可以确定DCI中实际可调度的传输块的最大数量等于所支持调度的传输块的最大数量。也就是说,终端设备可以确定DCI中包括至少一组信息域,该至少一组信息域的组数等于第一信令中所支持调度的传输块的最大数量,且该至少一组信息域中的每一组信息域分别用于指示一个传输块的调度信息。
例如,当第一信令所支持调度的传输块的最大数量为2,且信道秩和/或传输层数的最大取值大于4且小于或等于8时,表示DCI中实际可调度的传输块的最大数量为2,即网络设备向终端设备发送的DCI中包括两组信息域,每一组信息域分别用于指示一个传输块的调度信息。即网络设备向终端设备发送的DCI中包括第一组信息域和第二组信息域,其中,第一组信息域用于指示第一传输块的调度信息,第二组信息域用于指示第二传输块的调度信息。
又例如,当第一信令所支持调度的传输块的最大数量为1,且信道秩和/或传输层数的最大取值小于或等于4时,表示DCI中实际可调度的传输块的最大数量为2,即网络设备向终端设备发送的DCI中包括一组信息域,该一组信息域用于指示一个传输块的调度信息。
本申请实施例提供的技术方案,在第一信令和第二信令不匹配的情况下,即第一信令和第二信令所指示的传输块的最大数量不一致的情况下,终端设备可以不接受网络设备的调度指令。在第一信令和第二信令正确匹配的情况下,即第一信令和第二信令所指示的传输块的最大数量一致的情况下,终端设备才去接收网络设备的调度等指令,从而能够保证终端设备和网络设备之间的良好通信。
可选地,终端设备接收DCI的方式可以按照上文描述的方式进行接收。具体地,终端设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中包括的信息域的组数和/或信息域的类型。然后终端设备可以根据信息域的组数和/或信息域的类型,确定DCI的比特位长度,从而来正确接收DCI。
例如,当第一信令和第二信令所指示的传输块的最大数量都为1时,表示DCI中包括一组信息域,且该信息域的类型为第一类型,即该信息域用于指示传输块的调度信息。当第一信令和第二信令所指示的传输块的最大数量都为2时,表示DCI中包括两组信息域,且该两组信息域的类型为第一类型,即该两组信息域中的每组信息域分别用于指示一个传输块的调度信息。
需要说明的是,上文描述的方案中,DCI中所支持调度的传输块的最大数量可以理解为第一信令所指示的DCI中能够调度的传输块的最大数量。DCI中实际可调度的传输块的最大数量可以理解为网络设备向终端设备发送的DCI中能够调度的传输块的最大数量。传输块的调度信息是指传输块的独立调度信息。第一类型信息域包括以下信息域中的至少一种:MCS信息域、NDI信息域、RV信息域等。
图3是本申请实施例提供的一种传输下行控制信息的方法300的示意性流程图。该方法300可选地 可以应用于图1所示的系统,但并不限于此。如图3所示,该方法300包括以下至少部分内容。
在步骤310中,终端设备接收第一信令,以及接收第二信令,其中,所述第一信令用于指示下行控制信息所支持调度的传输块的最大数量,所述第二信令用于指示所述终端设备反馈信道质量信息所支持的信道秩和/或传输层数的最大取值;
在步骤320中,所述终端设备根据所述所支持调度的传输块的最大数量、所述信道秩和/或传输层数的最大取值,确定是否接收所述下行控制信息。
可选地,当所述信道秩和/或传输层数的最大取值小于或等于第一阈值,所述所支持调度的传输块的最大数量小于或等于第二阈值时,接收所述下行控制信息。或者,当所述信道秩和/或传输层数的最大取值大于第一阈值,所述所支持调度的传输块的最大数量大于第二阈值时,接收所述下行控制信息。
可选地,当信道秩和/或传输层数的最大取值小于或等于第一阈值,所述所支持调度的传输块的最大数量大于第二阈值时,不接收所述下行控制信息。或者,当所述信道秩和/或传输层数的最大取值大于第一阈值,所述所支持调度的传输块的最大数量小于或等于第二阈值时,不接收所述下行控制信息。
可选地,DCI可用于调度共享信道传输,当传输共享信道使用的传输层数等于所述第一阈值时,所述共享信道中包括的传输块的数量等于所述第二阈值。
可选地,当第一阈值为4时,所述第二阈值为1;和/或,当第一阈值为8时,所述第二阈值为2。
图4是本申请实施例提供的一种传输下行控制信息的方法400的示意性流程图。该方法400可选地可以应用于图1所示的系统,但并不限于此。如图4所示,该方法400包括以下至少部分内容。
在步骤410中,网络设备发送第一信令,以及发送第二信令,该第一信令用于指示下行控制信息中所支持调度的传输块的最大数量,该第二信令用于指示终端设备反馈信道质量信息所支持的信道秩和/或传输层数的最大取值。其中,第一信令可以为高层信令,第二信令可以为高层信令。所支持调度的传输块的最大数量可以为1或2,信道秩和/或传输层数的最大取值可以为大于或等于1且小于或等于8的正整数。
在步骤420中,网络设备根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,发送下行控制信息。
基于以上方案,网络设备依据第一信令指示的下行控制信息中所支持调度的传输块的最大数量,以及第二信令指示的所述终端设备反馈信道质量信息所支持的信道秩和/或传输层数的最大取值,来进行下行控制信息的发送,使得下行控制信息动态指示的传输模式(例如,MIMO传输模式)依赖于终端设备反馈的信道状态信息以及下行控制信息的设置,避免半静态配置传输模式,因此可以在下行控制信息设置方面来灵活支持多种传输方式,提高通信系统的灵活性。
可选地,在步骤420中,当信道秩和/或传输层数的最大取值小于或等于第一阈值,所支持调度的传输块的最大数量小于或等于第二阈值时,网络设备发送DCI。当信道秩和/或传输层数的最大取值大于第一阈值,所支持调度的传输块的最大数量大于第二阈值时,网络设备发送DCI。
可选地,在步骤420中,网络设备可以不受限于第一信令和第二信令所指示的信息,都会去发送DCI。
下面对网络设备发送DCI的方式进行描述。
可选地,在步骤420中,网络设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中包括的信息域的情况,该信息域的情况例如可以是信息域的组数、信息域的类型和/或信息域的其他信息等。进一步地,网络设备可以根据信息域的情况来发送DCI。
以信息域的情况为信息域的组数和/或信息域的类型为例,网络设备可以根据信息域的组数和/或信息域的类型,确定DCI的比特位长度,从而来发送DCI。
需要说明的是,信息域的类型可以根据信息域所指示的信息来进行划分。
DCI可用于调度共享信道传输,为方便描述,将在传输共享信道使用的传输层数等于信道秩和/或传输层数的最大取值的情况下,共享信道包括的传输块的数量称为第二数量,将第一信令中可支持调度的传输块的最大数量称为第一数量。
具体地,网络设备可以确定下行控制信息中包括的信息域的组数等于第一数量。
当第一数量大于第二数量时,该第一数量组信息域包括第二数量组信息域和其他组信息域。该第二数量组信息域的类型为第一类型,第一类型信息域用于指示传输块的调度信息。其他组信息域的类型为第二类型,该第二类型信息域用于指示第一信息。该第一信息与传输块调度信息不同,即第二类型信息域用于指示与传输块的调度信息无关的信息。该第一信息可以包括以下信息中的至少一种:业务等级、CBG信息及其相关信息、BWP信息及其相关信息等。
应理解,其他组信息域的组数可以为第一数量与第二数量的差值,也可以小于第一数量与第二数量的差值。
本申请实施例提供的技术方案中,当第一信令所指示的传输块的最大数量大于第二信令所指示的传输块的最大数量时,可以将DCI中的第二数量组信息域用于指示传输块调度信息,将其他组信息域用于指示与传输块调度无关的其他信息,这样可以在不增加信令的情况下传输其他信息,能够节省信令开销,达到重用DCI信息域的目的。
当第一数量等于第二数量时,DCI中信息域的组数等于第一数量组,该第一数量组信息域的类型为第一类型,该第一数量组信息域中的每一组信息域分别用于指示一个传输块调度信息。网络设备可以根据DCI中信息域的组数和/或信息域的类型,确定该DCI的比特位长度,从而来发送DCI。
当第一数量小于第二数量时,DCI中信息域的组数等于第一数量。该第一数量组信息域的类型为第一类型,该第一数量组信息域中的每一组信息域分别用于指示一个传输块调度信息。网络设备可以根据DCI中信息域的组数和/或信息域的类型,确定该DCI的比特位长度,从而来发送DCI。
此外,网络设备还可以向终端设备发送第一PDSCH,并根据DCI中的信息域的组数和/或信息域的类型,接收终端设备发送的第一PDSCH对应的ACK/NACK反馈信息。该ACK/NACK反馈信息的比特数目等于第二数量与第一数量中的最小值,即该ACK/NACK反馈信息的比特数目等于DCI中第一类型信息域的组数,也就是说,该ACK/NACK反馈信息的比特数目等于DCI中用于指示传输块调度信息的信息域的组数。
例如,当第一数量大于第二数量时,ACK/NACK反馈信息的比特数目等于第二数量。以第一数量为2,第二数量为1进行详细描述。DCI中包括2组信息域,其中一组信息域用于指示一个传输块的调度信息,另一组信息域用于指示与传输块调度信息无关的第一信息。网络设备可以向终端设备发送第二PDSCH,并根据第二数量为1确定第二PDSCH对应的ACK/NACK反馈信息为1个比特。然后根据该ACK/NACK反馈信息为1个比特,接收第二PDSCH对应的ACK/NACK反馈信息。
可选地,在步骤420中,网络设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定所述DCI中包括的信息域的组数和/或信息域的类型。进而网络设备可以根据该信息域的组数和/或信息域的类型,发送DCI。
可选地,网络设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中实际可调度的传输块的最大数量,并根据DCI中实际可调度的传输块的最大数量,发送DCI。
本申请实施例对网络设备确定DCI中实际可调度的传输块的最大数量的方式不做具体限定。
作为一种示例,网络设备可以直接根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中实际可调度的传输块的最大数量。
作为另一种示例,网络设备可以根据表1所示的传输层数与码字的对应关系,确定当传输共享信道使用的传输层数等于信道秩和/或传输层数的最大取值时,共享信道所包含的传输块的数量。进一步根据共享信道所包含的传输块的数量和所支持调度的传输块的最大取值,确定DCI中实际可调度的传输块的最大数量。
下面对网络设备确定DCI中实际可调度的传输块的最大数量进行详细描述。
为方便描述,将DCI中实际可调度的传输块的最大数量称为第三数量,将在传输共享信道使用的传输层数等于信道秩和/或传输层数的最大取值的情况下,共享信道包括的传输块的数量称为第二数量,将第一信令中所支持调度传输块的最大数量称为第一数量。以NR系统为例,第一数量、第二数量、第三数量可以分别取值为1或2。
可选地,网络设备可以确定第三数量为第二数量和第一数量中的最大值。
例如,第一数量为2,当第二数量为1,或者第一数量为1,第二数量为2,或者第一数量为2,第二数量为2时,网络设备可以确定第三数量为2。当第三数量为2时,表示网络设备向终端设备发送的DCI中包括2组信息域,且2组信息域中的每组信息域分别用于指示一个传输块调度信息。
又例如,当第一数量1,第二数量为1时,网络设备可以确定第三数量为1。当第三数量为1时,表示网络设备向终端设备发送的DCI中只有1组信息域,该一组信息域用于指示一个传输块调度信息。
可选地,网络设备也可以确定第三数量为第二数量和第一数量中的最小值。
例如,当第一数量为2,第二数量为1,或者第一数量为1,第二数量为2,或者第一数量为1,第二数量为1时,网络设备可以确定第三数量为1。当第三数量为1时,表示网络设备向终端设备发送的DCI中只有1组信息域,该一组信息域用于指示一个传输块调度信息。
又例如,当第一数量2,第二数量为2时,网络设备可以确定第三数量为2。当第三数量为2时,表示网络设备向终端设备发送的DCI中包括2组信息域,且2组信息域中的每组信息域分别用于指示一个传输块调度信息。
此外,网络设备也可以确定第三数量为第二数量和第一数量的平均值。
本申请实施例提供的技术方案,可以在第一信令和第二信令不匹配的情况下,即第一信令和第二信 令所指示的传输块的最大数量不一致的情况下,提供一种通过确定DCI中实际可调度的传输块的最大数量来发送DCI的方式,能够实现终端设备与网络设备之间的良好通信。
当网络设备确定DCI中实际可调度的传输块的最大数量为第三数量时,可以根据该第三数量向终端设备发送DCI。进一步向终端设备发送第一PDSCH,并根据DCI中的信息域的组数和/或信息域的类型,接收终端设备发送的第一PDSCH对应的ACK/NACK反馈消息,该ACK/NACK反馈信息的比特数目等于第三数量。具体地,网络设备可以根据第三数量确定第一PDSCH对应的ACK/NACK反馈消息的比特数目,然后根据该第一PDSCH对应的ACK/NACK反馈消息的比特数目,接收终端设备发送的ACK/NACK反馈消息。
可选地,在步骤420中,网络设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值不发送DCI。
例如,当信道秩和/或传输层数的最大取值小于或等于第一阈值,且所支持调度的传输块的最大数量大于第二阈值时,网络设备发送DCI。或者,当信道秩和/或传输层数的最大取值大于第一阈值,且所支持调度的传输块的最大数量小于或等于第二阈值时,网络设备不发送DCI。
可选地,在步骤420中,网络设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,发送DCI。
例如,当信道秩和/或传输层数的最大取值小于或等于第一阈值,且所支持调度的传输块的最大数量小于或等于第二阈值时,网络设备发送DCI。或者,当信道秩和/或传输层数的最大取值大于或等于第一阈值,且所支持调度的传输块的最大数量大于或等于第二阈值时,网络设备发送DCI。
其中,DCI可用于调度共享信道传输,当传输共享信道使用的传输层数等于第一阈值时,共享信道包括的传输块的数量等于第二阈值。
可选地,当第一阈值为4时,第二阈值为1;和/或,当第一阈值为8时,第二阈值为2。
以表1为例,当信道秩和/或传输层数的最大取值小于或等于4,且所支持调度的传输块的最大数量为1时,网络设备向终端设备发送DCI。或者,当信道秩和/或传输层数的最大取值小于或等于8,且所支持调度的传输块的最大数量等于1时,网络设备向终端设备发送DCI。或者,当信道秩和/或传输层数的最大取值大于4且小于或等于8,且所支持调度的传输块的最大数量等于2时,网络设备向终端设备发送DCI。其中,当传输共享信道使用的传输层数等于4时,共享信道包括的传输块的数量等于1。
当信道秩和/或传输层数的最大取值小于或等于4,且所支持调度的传输块的最大数量为2时,或者当信道秩和/或传输层数的最大取值大于4且小于或等于8,且所支持调度传输块的最大数量为2时,网络设备可以不向终端设备发送DCI。
可选地,当信道秩和/或传输层数的最大取值小于5,且所支持调度的传输块的最大数量为2时,网络设备向终端设备发送DCI。或者,当信道秩和/或传输层数的最大取值小于或等于8,且所支持调度的传输块的最大数量等于1时,网络设备向终端设备发送DCI。或者,当信道秩和/或传输层数的最大取值大于或等于5且小于或等于8,且所支持调度的传输块的最大数量等于2时,网络设备向终端设备发送DCI。
当信道秩和/或传输层数的最大取值小于5,且所支持调度的传输块的最大数量为1时,或者当信道秩和/或传输层数的最大取值大于或等于5且小于或等于8,且所支持调度传输块的最大数量为1时,网络设备可以不向终端设备发送DCI。
可选地,网络设备可以根据表1所示的传输层数与码字的对应关系,确定当共享信道使用的传输层数等于信道秩和/或传输层数的最大取值时,共享信道中包括的传输块的数量。进一步再根据共享信道中包括的传输块的数量和所支持调度的传输块的最大数量,确定是否发送DCI。
具体地,当共享信道中包括的传输块的数量与所支持调度的传输块的最大数量相等时,网络设备发送DCI。当共享信道中包括的传输块的数量与所支持调度的传输块的最大数量不相等时,网络设备可以不发送DCI。
当信道秩和/或传输层数的最大取值小于或等于第一阈值,且所支持调度的传输块的最大数量小于或等于第二阈值时,或者,当信道秩和/或传输层数的最大取值大于或等于第一阈值,且所支持调度的传输块的最大数量大于或等于第二阈值时,网络设备可以确定DCI中实际可调度的传输块的最大数量等于所支持调度的传输块的最大数量。也就是说,网络设备可以确定DCI中包括至少一组信息域,该至少一组信息域的组数等于第一信令中所支持调度的传输块的最大数量,且该至少一组信息域中的每一组信息域分别用于指示一个传输块的调度信息。
例如,当第一信令所支持调度的传输块的最大数量为2时,且信道秩和/或传输层数的最大取值大于4且小于或等于8时,表示网络设备向终端设备发送的DCI中包括两组信息域,每一组信息域分别用于指示一个传输块的调度信息。即网络设备向终端设备发送的DCI中包括第一组信息域和第二组信 息域,第一组信息域用于指示第一传输块的调度信息,第二组信息域用于指示第二传输块的调度信息。
又例如,当第一信令所支持调度的传输块的最大数量为1,且信道秩和/或传输层数的最大取值大于或等于4时,表示网络设备向终端设备发送的DCI中包括一组信息域,该一组信息域用于指示一个传输块的调度信息。
本申请实施例提供的技术方案,在第一信令和第二信令不匹配的情况下,即第一信令和第二信令所指示的传输块的最大数量不一致的情况下,网络设备可以不向终端设备发送DCI。在第一信令和第二信令正确匹配的情况下,即第一信令和第二信令所指示的传输块的最大数量一致的情况下,网络设备才和终端设备进行正常通信,从而能够保证终端设备和网络设备之间的良好通信。
可选地,网络设备发送DCI的方式可以按照上文描述的方式进行接收。具体地,网络设备可以根据所支持调度的传输块的最大数量、信道秩和/或传输层数的最大取值,确定DCI中包括的信息域的组数和/或信息域的类型。然后网络设备可以根据信息域的组数和/或信息域的类型来发送DCI。
例如,当第一信令和第二信令所指示的传输块的最大数量都为1时,表示DCI中包括一组信息域,且该信息域的类型为第一类型,即该信息域用于指示传输块的调度信息。当第一信令和第二信令所指示的传输块的最大数量都为2时,表示DCI中包括两组信息域,且该两组信息域的类型为第一类型,即该两组信息域中的每组信息域分别用于指示一个传输块的调度信息。
需要说明的是,上文描述的方案中,DCI中所支持调度的传输块的最大数量可以理解为第一信令中所指示的DCI中能够调度的传输块的最大数量。DCI中实际可调度的传输块的最大数量可以理解为网络设备向终端设备发送的DCI中能够调度的传输块的最大数量。传输块调度信息是指传输块的独立调度信息。第一类型信息域包括以下信息域中的至少一种:MCS信息域、NDI信息域、RV信息域等。
