Description

一种上行数据信道多业务UCI复用方法
本申请要求在2018年6月6日提交中国专利局、申请号为201810574954.1，发明名称为“一种上行数据信道多业务UCI复用方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及移动通信领域，尤其涉及一种上行数据信道多业务UCI复用的方法。
背景技术
NR支持eMBB、URLLC、mMTC三大业务，对于URLLC业务，用户面上行时延目标是0.5ms，下行也是0.5ms。通常URLLC一次传送的可靠性要求为：用户面时延1ms内，传送32字节包的可靠性为1-10^(-5)。由于业务的多样性，会出现多种业务复用的情况。NR系统中，PUSCH可以承载终端设备发送的上行共享信道UL-SCH和/或上行控制信息UCI。当多种业务复用时，会出现不同业务类型的数据和不同业务类型UCI复用的情况。
当UCI在PUSCH发送的时候，考虑到多种业务复用，会出现多种情况。以eMBB和URLLC复用为例，一种情况是相同业务类型(eMBB或者URLLC)的UCI复用在PUSCH上发送，第二种情况是eMBB UCI在URLLC PUSCH上发送，第三种情况是URLLC UCI在eMBB PUSCH上发送，这三种情况下的UCI信息信道编码的比特数目确定方式是不同的。
发明内容
本发明提出一种上行数据信道多业务UCI复用方法，解决不同业务的UCI信息信道编码的比特数目不同的问题。
本申请实施例提供一种上行数据信道UCI多业务复用方法，根据36.213标准，用UCI控制信息相对于UL-SCH的码率偏移量来计算编码后信息传输的调制符号数目；在高层信令中包含缩放参数，用于调整所述码率偏移量值。
进一步地，当相同业务类型的UCI复用在PUSCH上时，所述缩放参数标识的值为1。
进一步、且可选择地，当URLLC业务的UCI复用在eMBB业务的PUSCH上时，所述缩放参数标识的值小于1。
进一步、且可选择地，当eMBB业务的UCI复用在URLLC业务的PUSCH上时，所述缩放参数标识的值为1。
优选地，在本申请任意一项方法实施例中，所述UCI控制信息，包含以下信息中至少一种：HARK-ACK信息、CSI信息。所述缩放参数为至少一个，分别用于以下至少一种参数：HARK-ACK信息相对于UL-SCH的码率偏移量；CSI信息相对于UL-SCH的码率偏移量。
在本申请任意一项方法实施例中，所述高层信令为动态配置或半静态配置。
在本申请任意一项方法实施例中，所述业务类型包括eMBB、URLLC和mMTC中至少一种。
本申请实施例采用的上述至少一个技术方案能够达到以下有益效果：
为了尽量统一在不同业务复用和单一业务下的信令设置，设计一种指示码率偏移量β offset的方法，可以同时应用到不同业务复用的场景中。
附图说明
此处所说明的附图用来提供对本申请的进一步理解，构成本申请的一部分，本申请的示意性实施例及其说明用于解释本申请，并不构成对本申请的不当限定。在附图中：
图1为本发明上行数据信道UCI多业务复用方法的步骤示意图。
具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中 的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在NR eMBB UCI信息的信道编码格式，由高层信令通过偏移量beta-offset进行指示，该信息以UL-SCH的编码率为基础，UCI信息信道编码率的偏移量，由此确定需要的用于编码后信息传输的调制符号的数目。
β offsett是UCI控制信息相对UL-SCH的码率偏移量是RRC配置的，标准中以列表的方式给出了所支持的偏移量选项，配置β offset的表格包括32个可能的数值，所有的数值都不小于1。这种方法适用于单一业务(eMBB或者URLLC)业务的UCI在PUSCH上发送。
以HARQ-ACK在PUSCH上复用的方法为例，用于发送HARQ-ACK的资源(编码后信息传输的调制符号数目)基于以下公式计算：

Figure PCTCN2019071427-appb-000003
是HARQ-ACK相对应UL-SCH的码率偏移量(β offset)。公式1以及M和N等符号的含义参照标准36.213。
本专利考虑到不同业务类型复用时候的UCI在PUSCH UL-SCH发送，考虑到不同业务类型的可靠性发送不同，引入一个缩放因子β scale参数，用于计算UCI的信息信道编码后的比特数目，并且该β scale参数是动态信令指示的。
以下结合附图，详细说明本申请各实施例提供的技术方案。
图1为本发明上行数据信道UCI多业务复用方法的步骤示意图。本申请实施例提供一种上行数据信道UCI多业务复用方法，包含以下步骤：
步骤10、在高层信令中包含缩放参数，用于调整UCI控制信息相对于UL-SCH的码率偏移量值；
例如，考虑到eMBB的UCI复用在URLLC数据业务UL-SCH的时候，URLLC数据要有更高的可靠性，因此相应的数值要小于1。当URLLC的UCI复用在eMBB PUSCH的时候，β offset要在现有表格基础上进一步提升，使得编码调制符号数更多，降低UCI的编码率，提升可靠性。
为了达到这一目的，本专利提出，在已有β offset表格的基础上，通过动态信令或者半静态配置信令来指示缩放系数β scale，当需要降低β offset的时候，β scale的数值小于1，当需要提升β offset的时候，β scale的数值大于1，复用的UCI业务类型相同时，β scale的数值为1。也就是当动态信令指示βscale的数值的时候，使用调整后的码速偏移量β′ offset＝β scale×β offset，其中β offset为RRC配置列表中的数值。
例如，当用于HARK-ACK时，β offset表示为

取值如下表：

其中，当终端设备(UE)发送不大于比特2的HARQ-ACK比特的时候高层配置

当UE发送大于2比特小于等于11比特的时候高层配置
Figure PCTCN2019071427-appb-000008
UE发送大于11比特的时候高层配置
Figure PCTCN2019071427-appb-000009
实施例1
优选地，当相同业务类型的UCI复用在PUSCH上时，所述缩放参数标识的值为1。
实施例2
优选地，当URLLC业务的UCI复用在eMBB业务的PUSCH上时，所述缩放参数标识的值小于1。
实施例3
优选地，且可选择地，当eMBB业务的UCI复用在URLLC业务的PUSCH上时，所述缩放参数标识的值为1。
步骤20、用所述调整后的码率偏移量来计算编码后信息传输的调制符号 数目。
以HARQ-ACK在PUSCH上复用的方法为例，考虑到不同业务复用时候的UCI在PUSCH发送的情况，本专利不更改配置表格中的β offset数值，引入缩放因子β scale，通过动态信令配置该缩放因子，用来确定用户HARQ-ACK信息信道编码后的比特数目为：
Figure PCTCN2019071427-appb-000010
与公式1相同，这里的O是HARQ-ACK信息比特数目，
Figure PCTCN2019071427-appb-000011
表示了对应的初次传输中“物理信道PUSCH所包含的调制符号的总数”与“UL-SCH编码后比特总数”的比值，反应了UL-SCH的编码率。M和N等符号的含义参照标准36.213。
与公式1不同的是，
Figure PCTCN2019071427-appb-000012
是使用缩放参数
Figure PCTCN2019071427-appb-000013
对值HARQ-ACK相对应UL-SCH的码率偏移量
Figure PCTCN2019071427-appb-000014
进行调整后的值，即所述调整后的码速偏移量β′ offset用于HARQ-ACK的值。
通过缩放参数调整码率偏移量值、再用UCI控制信息相对于UL-SCH的码率偏移量来计算编码后信息传输的调制符号数目，从而能够根据不同业务类型的复用，灵活的确定用户HARQ-ACK信息信道编码后的比特数目。
优选地，在本申请任意一项方法实施例中，所述UCI控制信息，包含以下信息中至少一种：HARK-ACK信息、CSI信息。所述缩放参数为至少一个，分别用于以下至少一种参数：HARK-ACK信息相对于UL-SCH的码率偏移量；CSI信息相对于UL-SCH的码率偏移量。
也就是说，β scale数值适用于所有的UCI信息，包括HARQ-ACK和CSI 信息。并且该β scale的数值可以是所有的UCI统一的，也就是HARQ-ACK和CSI信息对应的β scale数值是统一的，也可以是每个不同的UCI分离配置的，也就是HARQ-ACK信息和CSI信息可以配置不同的β scale数值。
在本申请任意一项方法实施例中，所述高层信令为动态配置或半静态配置。
在本申请任意一项方法实施例中，所述业务类型包括eMBB、URLLC和mMTC中至少一种。
本专利考虑到当eMBB和URLLC业务复用的时候，可能出现的不同类型业务的UCI和PUSCH复用的问题，通过引入动态信令指示缩放因子beta_scale参数，当同业务类型复用的时候，配置β scale参数为1，当URLLC UCI复用在eMBB上行数据的时候，配置β scale参数小于1，当eMBB UCI复用在URLLC上行数据的时候，配置β scale参数大于1，通过这种方式实现了不同业务复用时的UCI在PUSCH上发送。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
