类型一的层映射方案和类型二的层映射方案将两个码字进行层映射后的层数差值的最大值不同。示例性的,类型一的层映射方案和类型二的层映射方案对层数不作出任何限制,仅是两个码字进行层映射后的层数差值的最大值不同。
示例性的,类型一的层映射方案和类型二的层映射方案可以应用在上行码字的发送场景,也可以应用在下行码字的发送场景;本申请的实施例以应用在上行码字为例进行说明。
综上所述,本实施例提供的方法,通过终端向网络设备上报终端的能力信息,实现了网络设备掌握终端支持使能类型二的层映射方案的情况;通过类型二的层映射方案可以对两个码字进行层映射后的传输层数进行灵活配置,通过对传输层数进行灵活配置可以适应不同场景下的传输需求。
接下来,对层映射方案进行示例性介绍:
类型1的层映射方案:
以总传输层数的最大值为8层为例,如图3所示,类型1的层映射方案包括1个码字和2个码字对应的8种层映射方案。在类型1的层映射方案下,1个码字进行层映射后对应的传输层数大于0、且小于或等于4。若2个码字包括第一码字和第二码字;第一码字进行层映射后对应第一传输层数,第二码字进行层映射后对应第二传输层数;在类型1的层映射方案下,第一传输层数与第二传输层数之间的层数差值为0或1,且第一传输层数和第二传输层数的总和大于4、且小于或等于8。示例性的,1个码字(包括CW0)对应的类型1的层映射方案包括以下4种:

由上述类型一的层映射方案的描述可知,类型一的层映射方案中的第一传输层数与第二传输层数之间的差值为零或一,类型二的层映射方案第一传输层数与第二传输层数之间的最大层数差值允许大于1,可见类型二的层映射方案相较于类型一的层映射方案更加灵活。以总传输层数的最大值为8层为例,类型二的层映射方案中的第一传输层数和第二传输层数之间的层数差值可以为零至六中的任一整数。比如,CW0映射到传输层1,CW1映射到传输层2至7,总传输层数为8,第一传输层数和第二传输层数之间的层数差值为六。

针对类型2的层映射方案中对4层以上(含4层)的传输支持传输两个码字的方案。
如图5所示,在类型2的层映射方案为对4层以上(含4层)的传输支持传输两个码字时,2个码字(包括CW0和CW1)对应的类型2的层映射方案在图4的基础上还包括以下2种:
·CW0映射到1个传输层,CW1映射到3个传输层;
比如,CW0映射到传输层1,CW1映射到传输层2至4,总传输层数为4。

图16提供了本申请一个实施例提供的码字的层映射上报方法的流程图,该方法中的终端可以由图1所示的终端执行,该方法包括:
步骤610:终端上报是否支持类型二的层映射方案;
示例性的,终端通过使用RRC信令、MACCE信令、UCI信令中的至少之一进行上报;
具体的,终端上报是否支持类型二的层映射方案至少包括以下三种能力类型:
·能力类型一:终端只支持4层以上的层映射类型二的层映射方案;
·能力类型二:终端支持包括4层及以上的层映射类型二的层映射方案,其中4层为支持2个码字的灵活层映射;
·能力类型三:终端支持包括2层及以上的层映射类型二的层映射方案,其中2-4层支持2个码字的灵活层映射;
接下来,对类型一的层映射方案和类型二的层映射方案进行介绍:
·类型一的层映射方案:
示例性的,码字到层的映射采用了尽可能均衡的方式。秩为奇数时,码字0的层数比码字1少一层。秩为偶数时,两个码字对应的层数一致的码字到层的映射方式。
·类型二的层映射方案:
示例性的,对于5-8层的码字灵活层映射;
灵活地映射也分为两个码字,但是两个码字各自对应的层数不受限制,根据实际的信道条件确定,因此可能会出现多种组合,比如,6层的传输可能CW0对应4层数据,CW1对应2层数据。
可选的,同时对于2-4层对应一个码字的情况也使用2个码字来灵活映射。
在上行或者下行的层映射方案中,数据层数为2-4层的情况对应1个码字的传输。而这种配置很难使得同一个MCS适应不同层的信道条件,因此在层间信道性能差异较大的情况下,就会出现性能损失的情况。因此对于2-4层或者仅针对4层的数据也应用2个码字进行调度和传输,这样网络可以充分根据层间信道条件进行调度。
比如:对应3层传输,在信道层间差异较大的情况下可以使用2个码字进行调度,对应一个码字传输1层数据,另外一个码字传输2层数据。这样也方便数据重传调度,有利于提高系统吞吐量。系统中4层以下的传输为主,因此对于整体的性能优化也是有好处的。
步骤620:终端在满足触发条件的情况下,上报建议调度类型二的层映射方案的信息;
示例性的,终端通过MACCE信令上报建议网络调度规则为类型二的层映射方案;
可选的,终端可以通过测量,通过DCI信令指示上报建议网络调度规则为类型二的层映射方案,如,DCI信令中增加独立指示域,或通过DMRS指示域码点(Codepoint)增加信息量指示。
示例性的,触发条件包括但不限于如下至少之一:
·单传输接收点(Single-Transmission Reception Point,S-TRP)或多传输接收点 (Multiple-Transmission Reception Point,M-TRP)下,终端检测到层间的信干噪比(Signal to Interference plus Noise Ratio,SINR)差异大于第一门限;
·M-TRP场景下,终端通过测量协作TRP的信道质量指示(Channel Quality Indicator,CQI)差异大于第二门限;
·终端在波束测量时测量的一组上报波束参考信号接收功率(Reference signal received power,RSRP)或L1-SINR差异大于第三门限;
·多层传输下的TB的连续重传事件发生,如:连续重传事件配置的计数器达到第四门限,或,连续重传事件配置的定时器超时。
进一步的,终端上报建议调度类型二的层映射方案的信息后,可以由基站决策层映射方案的调度;也可以在终端上报后默认基站改变层映射方案,由终端决策层映射方案的调度。
示例性的,在终端决策层映射方案的调度的情况下,终端定义决策生效时间;在类型二的层映射方案适用的PUSCH传输情况下,即传输秩指示(Rank Indication,RI)限制,将默认使用类型二的层映射方案进行PUSCH发送。
综上所述,本实施例提供的方法,通过终端向网络设备上报终端的能力信息,实现了网络设备掌握终端支持使能类型二的层映射方案的情况;通过类型二的层映射方案可以对两个码字进行层映射后的传输层数进行灵活配置,通过对传输层数进行灵活配置可以适应不同场景下的传输需求。
