Description
本公开涉及通信技术领域,特别涉及一种传输上行业务数据的方法、装置和系统。
在LTE(Long Term Evolution,长期演进技术)网络中,当UE(User Equipment,用户设备)有上行业务数据和上行控制信息要向基站传输时,如果上行业务数据和上行控制信息的传输在时域上发生重合,UE可以将上行控制信息视为上行业务数据的一部分一起进行传输,即LTE中的UCI piggyback方式。与将上行控制信息和上行业务数据分别进行独立传输相比,使用UCI piggyback方式同时传输上行业务数据和上行控制信息,可以降低上行传输的峰均比,从而避免了复杂的上行功率控制等。
在5G(fifth-generation of wireless mobile telecommunications technology,第五代通信移动技术)中,为了更好的支持多波束大规模天线的使用,5G中将某些上行控制信息如CSI(channel state information,信道测量反馈信息)分为两部分,即第一部分上行控制信息和第二部分上行控制信息。第一部分上行控制信息的数据量和所占用的时频资源块的数目是基站可以根据系统配置确定的,而第二部分上行控制信息的数据量和所占用的时频资源块的数目是基站事先无法确定,只有通过正确恢复第一部分上行控制信息之后才能得知。
如果5G中也有上行业务数据和上行控制信息同时要向基站传输,UE也可以使用LTE中UCI piggyback方式同时传输上行业务数据和上行控制信息。基站在接收到上行业务数据、第一部分和第二部分上行控制信息后,应该首先根据系统配置和预设的时频资源映射规则,确定第一部分上行控制信息所占用的时频资源的位置,然后根据该位置,从时频资源上恢复第一部分上行控制信息,根据第一部分上行控制信息,确定第二部分上行控制信息所占用的时频资源的位置,然后再根据第一部分上行控制信息和第二部分上行控制信息所占用的时频资源块的位置,确定出上行业务数据所占用的时频资源块的位置,从中恢复出上行业务数据。
在实现本公开的过程中,发明人发现现有技术至少存在以下问题:
在5G中,如果想要恢复出上行业务数据,需要首先恢复出第一部分上行控制信息的内容,根据第一部分上行控制信息确定出第二部分上行控制信息所占用的时频资源的位置,根据第一部分上行控制信息和第二部分上行控制信息所占用的时频资源的位置,才能恢复出上行业务数据,所以恢复出上行业务数据依赖于对第一部分上行控制信息的确定,所以如果恢复第一部分上行控制信息的内容失败,有可能会导致恢复上行业务数据失败。另外基站恢复第一部分上行控制信息的过程会增加上行数据接收的延时。

本公开实施例提供的技术方案带来的有益效果是:
本公开实施例中,UE确定分配给本设备的时频资源、以及待传输的上行业务数据和上行控制信息,其中,上行控制信息至少包括第一部分上行控制信息和第二部分上行控制信息,根据预设的第一系统配置和预设的第一时频资源映射规则,在分配给本设备的时频资源中,确定第一部分上行控制信息所占用的时频资源的第一位置,根据第一位置、预设的第二时频资源映射规则、以及分配给本设备的时频资源中仅除去第一部分上行控制信息所占用的时频资源后的时频资源,确定每个CB分别所占用的时频资源的资源单元的起始位置,根据预设的第二系统配置、以及第二部分上行控制信息,确定第二部分上行控制信息所占用的时频资源的资源单元的第一数目,根据分配给本设备的时频资源中除去第一部分上行控制信息和第二部分上行控制信息所占用的时频资源后的时频资源,确定每个CB分别所占用的时频资源的资源单元的第二数目,根据每个CB分别所占用的时频资源的资源单元的起始位置、每个CB分别所占用的时频资源的资源单元的第二数目、以及预设的第二时频资源映射原则,确定每个CB所占用的时频资源的第二位置,根据第一位置和第二位置,将第一部分上行控制信息、第二部分上行控制信息和每个CB,分别映射至分配给本设备的时频资源中,进行传输。这样,采用上述方法,由于基站可以基于相同的计算方法,确定出每个CB的起始位置,然后恢复出上行业务数据,所以基站恢复出上行业务数据没有依赖第一部分上行信息的内容,所以即使恢复第一部分上行控制信息失败,也可以恢复到上行业务数据,进而可以提高上行业务数据的恢复率,而且由于不需要恢复出第一部分上行控制信息也能恢复出上行业务数据,所以恢复上行业务数据的延时也比较低。
为了更清楚地说明本公开实施例中的技术方案,下面将对实施例描述中所要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本公开的

这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开一示例性实施例提供了一种传输上行业务数据的方法,传输上行业务数据的方法的执行主体可以是基站和UE。
基站中可以设置有处理器、收发器和存储器等,处理器可以用于传输上行业务数据的相关处理,收发器可以用于接收以及发送数据,存储器可以用于传输上行业务数据过程中需要的数据以及产生的数据。
UE可以是手机等,UE可以设置有处理器、收发器和存储器等,处理器可以用于传输上行业务数据的相关处理,收发器可以用于接收以及发送数据,存储器可以用于传输上行业务数据过程中需要的数据以及产生的数据。UE还可以设置有屏幕等输入输出设备,用于显示业务数据等。
在进行实施前,如图1所示,首先介绍一下本公开实施例的应用场景,应用场景中涉及的设备有基站和UE,UE可以是手机等,UE可以将上行控制信
息和上行业务数据一起,通过时频资源进行发送,基站可以从时频资源中恢复到UE发送的上行业务数据和上行控制信息。
如图2所示,该方法的处理流程可以包括如下的步骤:
在步骤201中,UE确定分配给本设备的时频资源、以及待传输的上行业务数据和上行控制信息。
其中,上行控制信息至少包括第一部分上行控制信息和第二部分上行控制信息,第一部分上行控制信息可以是CSI中的Part1(第一部分)等,第二部分上行控制信息可以是CSI中的Part2(第二部分)等。
在实施中,UE有上行业务数据和上行控制信息要向基站发送时,可以向基站发送SR(Scheduling Request,上行调度请求),基站接收到UE发送的上行调度请求后,可以为该UE分配一小部分的时频资源,用于UE上传BSR(buffer state report,缓冲状态报告),UE可以通过BSR告知基站,待上传的上行业务数据和上行控制信息的数据量,基站接收到BSR后,为UE分配相应的上行时频资源,用于传输上行业务数据和上行控制信息。基站确定为UE分配的时频资源后,可以将分配结果告知UE,UE即可以确定分配给自己的时频资源。
在步骤202中,UE根据预设的第一系统配置和预设的第一时频资源映射规则,在分配给本设备的时频资源中,确定第一部分上行控制信息所占用的时频资源的第一位置。
其中,预设的第一系统配置可以由技术人员预设,并且分别存储至基站和UE中,例如,预设的第一系统配置中规定了计算第一部分上行控制信息所占用的时频资源的资源单元的数目的方法等,预设的第一时频资源映射规则一般有时域优先映射规则、频域优先映射规则等。
在实施中,UE确定分配给自己的时频资源后,确定第一部分上行控制信息的内容和数据量,然后可以获取存储的预设的第一系统配置,使用预设的第一系统配置、第一部分上行控制信息的数据量、以及信道测量结果等,计算出第一部分上行控制信息所占用的时频资源的资源单元的数目。然后使用预设的第一时频资源映射规则,确定第一部分上行控制信息所占用的时频资源的第一位置。例如,如图3所示,预设的第一时频资源映射规则是频域优先的规则,第一部分上行控制信息所占用的时频资源的资源单元的数目是5,第一位置就是和DMRS(Demodulation Reference Signal,解调参考信号)相邻的频域上的
5个资源单元。
可选的,预设的第一时频资源映射规则为时域优先映射规则或频域优先映射规则。
在实施中,基站和UE采用相同的第一时频资源映射规则,可以是基站和UE提前协商,预设的第一时频资源映射规则可以是时域优先映射规则或频域优先映射规则,时域优先映射规则指先将数据映射时域,再去考虑频域,频域优先映射规则是指先将数据映射至频域,再去考虑时域。
在步骤203中,UE根据预设的第二时频资源映射规则、以及分配给本设备的时频资源中仅除去第一部分上行控制信息所占用的时频资源后的时频资源,确定上行业务数据的每个CB分别所占用的时频资源的资源单元的起始位置。
其中,预设的第二时频资源映射规则可以由技术人员预设,并且存储至UE和基站中,第二时频资源映射规则可以和第一时频资源映射规则相同,也可以不相同,例如,第一时频资源映射规则和第二时频资源映射规则都是频域优先映射规则,或者第一时频资源映射规则是时域优先映射规则,第二时频资源映射规则是频域优先映射规则,或者第一时频资源映射规则是频域优先映射规则,第二时频资源映射规则是时域优先映射规则。
在实施中,上行业务数据一般是比特流,UE会按照一定的原则,将比特流分为多个比特流段,然后分别对多个比特流段,按照预设的编码方式进行编码,就得到多个CB(Code Block,编码块)。此处需要说明的是,上述将比特流分为多个比特流段的方式是基站与UE约定好的,每个CB的比特数可以相同,也可以不相同,例如,在LTE中,每个CB的编码前比特数不超过6144比特,当待传输数据的比特数超过6144比特时,会将待传输数据尽量均匀的分到多个CB中去。
UE确定第一部分上行控制信息所占用的时频资源的第一位置后,可以使用第一位置,在分配给自己的时频资源中除去第一部分上行控制信息所占用的时频资源,但是不除去第二部分上行控制信息所占用的时频资源,得到第一时频资源。如果上行业务数据的多个CB的数据量所需要的时频资源大于第一时频资源,可以分别对每个CB进行删除比特位的处理,使上行业务数据的多个CB可以与第一时频资源匹配,如果上行业务数据的多个CB的数据量所需要的时频资源小于第一时频资源,可以分别对每个CB进行发送冗余比特位的处
理,使上行业务数据的多个CB可以与第一时频资源匹配,该过程即可称为速率匹配,使上行业务数据的每个CB都恰好能映射至第一时频资源上。然后使用每个资源单元映射的数据的数据量、以及信道测量结果等,计算每个CB所占用的时频资源的资源单元的起始位置。例如,如图4所示,上行业务数据有4个CB,分别是CB1、CB2、CB3和CB4,CB1所占用的时频资源为从左边数第一条粗横线和第二条粗横线之间的时频资源,CB2所占用的时频资源为从左边数第二条粗横线和第三条粗横线之间的时频资源,CB3所占用的时频资源为从左边数第三条粗横线和第四条粗横线之间的时频资源,CB4所占用的时频资源为从左边数第四条粗横线和最后一条粗横线之间的时频资源,CB1、CB2、CB3和CB4的起始位置即为第一条粗黑线、第二条粗黑线、第三条粗黑线和第四条粗黑线。
同样,在确定出每个CB所占用的时频资源的起始位置后,实际上也可以确定出每个CB所占用的时频资源的结束位置。
可选的,UE可以使用每个CB所占用的时频资源的资源单元的数目,来确定每个CB所占用的时频资源的资源单元的起始位置,相应的处理可以如下:
根据分配给本设备的时频资源中仅除去第一部分上行控制信息所占用的时频资源后的时频资源,确定每个CB分别所占用的时频资源的资源单元的第三数目,根据预设的第二时频资源映射规则、以及每个CB分别所占用的时频资源的资源单元的第三数目,确定每个CB分别所占用的时频资源的资源单元的起始位置。
在实施中,UE可以使用第一位置,确定分配给自己的时频资源中除去第一部分上行控制信息所占用的时频资源,但是不除去第二部分上行控制信息所占用的时频资源后的时频资源,然后进行速率匹配(速率匹配的方法和前面相同),使用每个CB的数据量、以及每个资源单元映射的数据的数据量,确定出每个CB分别所占用的时频资源的资源单元的第三数目。
对于第一个CB,在分配给自己的时频资源中除去第一部分上行控制信息所占用的时频资源后的时频资源中,按照预设的第二时频资源映射规则,从该时频资源的开始位置即为第一个CB的起始位置,对于第二个CB,从该起始位置向后数第一个CB对应的第三数目个资源单元,即为第二个CB的起始位置,从依次类推,即可确定出每个CB所占用的时频资源的起始位置。
在步骤204中,UE根据预设的第二系统配置、以及第二部分上行控制信
息,确定第二部分上行控制信息所占用的时频资源的资源单元的第一数目。
其中,第二系统配置可以由技术人员预设,并且存储至UE和基站。预设的第二系统配置中规定了计算第二部分上行控制信息所占用的时频资源的资源单元的数目的方法等。
在实施中,UE对上行业务数据的每个CB进行第一次速率匹配之后,可以确定要发送的第二部分上行控制信息,进而可以确定出第二部分上行控制信息的内容和数据量,然后使用预设的第二系统配置,基于第二部分上行控制信息的数据量,来计算得到第二部分上行控制信息所占用的时频资源的资源单元的第一数目。
在步骤205中,UE根据分配给本设备的时频资源中除去第一部分上行控制信息和第二部分上行控制信息所占用的时频资源后的时频资源,确定每个CB分别所占用的时频资源的资源单元的第二数目。
在实施中,UE确定出第二部分上行控制信息所占用的时频资源的第二数目后,UE可以使用第一位置,得到第一部分上行控制信息所占用的时频资源的资源单元的数目,然后使用该第一数目和该数目,在分配给自己的时频资源中除去第一部分上行控制信息和第二部分上行控制信息所占用的时频资源,得到第二时频资源,然后使用第二时频资源,对每个CB进行速率匹配处理(与步骤203中的速率匹配处理相同,此处不再赘述),得到每个CB分别所占用的时频资源的资源单元的第二数目。例如,如图5所示,第二部分上行控制信息所占用的时频资源的资源单元的第一数目为9,上行业务数据有4个CB,分别是CB1、CB2、CB3和CB4,在进行速率匹配后,CB1所占用的时频资源为从左边数第一条粗横线和第二条粗横线之间的时频资源,CB2所占用的时频资源为从左边数第三条粗横线和第四条粗横线之间的时频资源,CB3所占用的时频资源为从左边数第五条粗横线和第六条粗横线之间的时频资源,CB4所占用的时频资源为从左边数第七条粗横线和第八条粗横线之间的时频资源,CB1、CB2、CB3和CB4分别占用的资源单元的第二数目为31、31、31、37。
需要说明的是,对于任一CB,在两次进行速率匹配时,由于所使用的时频资源是不一样的(第一次使用的是仅除去第一部分上行控制信息所占用的时频资源后的时频资源,第二次使用的是除去第一部分上行控制信息和第二部分上行控制信息所占用的时频资源后的时频资源),所以确定出所占用的时频资源的资源单元的数目不相同。而且对于任一CB,进行第一次速率匹配后该CB
所占用的资源单元的数目要大于进行第二次速率匹配后该CB所占用的资源单元的第一数目,这是由于在进行第二次速率匹配之后,上行业务数据所占用的时频资源变少的原因,变少的原因是将这部分时频资源用于传输第二部分上行控制信息。
在步骤206中,根据每个CB分别所占用的时频资源的资源单元的起始位置、每个CB分别所占用的时频资源的资源单元的第二数目、以及预设的第二时频资源映射原则,确定每个CB所占用的时频资源的第二位置。
在实施中,UE对每个CB进行第二次速率匹配处理后,对于任一CB,获取确定出的该CB的起始位置和占用的资源单元的第二数目,UE可以使用第二时频资源映射规则,从该CB的起始位置开始数第二数目个资源单元,则可确定出该CB所占用的时频资源的第二位置。使用相同的方法即可确定出每个CB所占用的时频资源的第二位置。
在步骤207中,UE根据第一位置和第二位置,将第一部分上行控制信息、第二部分上行控制信息和每个CB,分别映射至分配给本设备的时频资源中,进行传输。
在实施中,UE在确定每个CB所占用的时频资源的第二位置后,UE可以将第一部分上行控制信息映射至第一位置,将每个CB分别映射至对应的第二位置,然后确定分配给自己的时频资源中除去第一部分上行控制信息和上行业务数据所占用的时频资源后的时频资源,将第二部分上行控制信息映射至确定的时频资源上,进行传输。
可选的,可以首先确定第二部分上行控制信息所占用的时频资源的第三位置,再进行映射,相应的步骤207的处理可以如下:
在分配给本设备的时频资源中除去第一部分上行控制信息和上行业务数据所占用的时频资源后的时频资源中,确定第二部分上行控制信息占用的时频资源的第三位置,将第一部分上行控制信息、第二部分上行控制信息、以及每个CB,分别映射至第一位置、第三位置和第二位置,进行传输。
在实施中,UE在确定每个CB所占用的时频资源的第二位置后,UE可以使用第一位置,在分配给自己的时频资源中,确定出第一部分上行控制信息所占用的时频资源,并且使用每个CB对应的第二位置,在分配给自己的时频资源中,确定出每个CB所占用的时频资源。然后在分配给自己的时频资源中,除去第一部分上行控制信息和每个CB所占用的时频资源,得到剩余的时频资
源,剩余的时频资源即为第二部分上行控制信息所占用的时频资源,这样,剩余的时频资源的位置也就是第三位置。
UE在确定第一位置、第二位置和第三位置后,UE可以将第一部分上行控制信息映射至第一位置,并将第二部分上行控制信息映射至第三位置,并将每个CB分别映射自己对应的第二位置,进行传输。
如图5所示,上行业务数据有4个CB,分别是CB1、CB2、CB3和CB4,CB1所占用的时频资源为从左边数第一条粗横线和第二条粗横线之间的时频资源,CB2所占用的时频资源为从左边数第三条粗横线和第四条粗横线之间的时频资源,CB3所占用的时频资源为从左边数第五条粗横线和第六条粗横线之间的时频资源,CB4所占用的时频资源为从左边数第七条粗横线和第八条粗横线之间的时频资源,第二部分上行控制信息所分别占用的时频资源为从左边数第二条粗横线和第三条粗横线之间的时频资源、从左边数第四条粗横线和第五条粗横线之间的时频资源、从左边数第六条粗横线和第七条粗横线之间的时频资源、从左边数第八条粗横线和第九条粗横线之间的时频资源。
在步骤208中,基站通过分配给UE的时频资源,接收UE传输的上行控制信息和上行业务数据。
在实施中,基站可以在分配给UE的时频资源上,接收该UE传输的上行业务数据和上行控制信息。
在步骤209中,基站根据预设的第一系统配置、预设的第一时频资源映射规则、以及分配给UE的时频资源,确定第一部分上行控制信息所占用的时频资源的第一位置。
其中,此处的第一系统配置和步骤202中的第一系统配置相同。
在实施中,基站确定分配给UE的时频资源后,基站可以基于预先与UE的约定,确定出第一部分上行控制信息的数据量,然后可以获取存储的预设的第一系统配置,使用预设的第一系统配置、以及第一部分上行控制信息的数据量,计算出第一部分上行控制信息所占用的时频资源的资源单元的数目。然后使用预设的时频资源映射规则,确定第一部分上行控制信息所占用的时频资源的第一位置。
需要说明的是,基站与UE约定第一部分上行控制信息的数据量,所以即使不知道第一部分上行控制信息的内容,也可以得到第一部分上行控制信息的数据量。
在步骤210中,基站根据预设的第二时频资源映射规则、以及分配给UE的时频资源仅除去第一部分上行控制信息所占用的时频资源后的时频资源,确定上行业务数据的每个CB分别所占用的时频资源的资源单元的起始位置。
在实施中,基站可以使用第一部分上行控制信息所占用的时频资源的资源单元的第一位置,在分配给UE的时频资源资源中仅除去第一部分上行控制信息所占用的时频资源,但是不除去第二部分上行控制信息所占用的时频资源,得到第三时频资源,此处的第三时频资源与前面的第一时频资源是相同的,然后可以根据UE在步骤201中发送上行调度请求过程中,上行业务数据的数据量,按照预设的划分比特流规则,确定出上行业务数据中包括的CB的个数,以及每个CB的数据量,然后在第三时频资源中,对上行业务数据的每个CB进行速率匹配,使上行业务数据恰好能映射至第三时频资源中,这样就得到每个CB分别所占用的时频资源的资源单元的起始位置。
可选的,基站可以使用每个CB所占用的资源单元的数目,确定每个CB所占用的时频资源的资源单元的起始位置,相应的步骤210的处理可以如下:根据预设的第二系统配置、第一位置、以及分配给UE的时频资源仅除去第一部分上行控制信息所占用的时频资源后的时频资源,确定上行业务数据的每个CB分别所占用的时频资源的资源单元的第一数目;根据每个CB分别所占用的时频资源的资源单元的第一数目、以及预设的第二时频资源映射规则,确定每个CB分别所占用的时频资源的资源单元的起始位置。
在实施中,基站可以使用第一位置,确定分配给UE的时频资源中除去第一部分上行控制信息所占用的时频资源,但是不除去第二部分上行控制信息所占用的时频资源后的时频资源,然后进行速率匹配(速率匹配的方法和前面相同),使用每个CB的数据量、以及每个资源单元映射的数据的数据量,确定出每个CB分别所占用的时频资源的资源单元的第一数目,实际上此处的第一数目和步骤203中确定出的第三数目相同。
对于任一CB,UE可以使用第二时频资源映射规则、以及该CB对应的第一数目,确定出该CB所占用的时频资源的起始位置。例如,预设的第二时频资源映射规则为频域优先规则,基站确定有4个CB,分别是CB1、CB2、CB3和CB4,对应的第一数目为10、15、20、18,基站可以从第三时频资源的起始位置,按照频域优先规则,数10个资源单元,即为第一个CB(CB1),起始位置为第三时频资源的起始位置,然后从第11个资源单元起数15个资源单
元,即为第二个CB(CB2),起始位置为第11个资源单元,然后从第26个资源单元起数20个资源单元,即为第三个CB(CB3),起始位置为第26个资源单元,然后从第46个资源单元起数18个资源单元,即为第四个CB(CB4),起始位置为第46个资源单元。这样,就确定出每个CB所占用的时频资源的起始位置。
在步骤211中,根据每个CB分别所占用的时频资源的资源单元的起始位置、预设的第二时频资源映射规则,确定每个CB分别所占用的时频资源的资源范围,在每个CB分别所占用的时频资源的资源范围中分别截去预设数目个资源单元后的时频资源中,恢复每个CB,得到上行业务数据。
其中,预设的第二时频资源映射规则可以由技术人员预设,并且存储至基站中,基站与UE所使用的时频资源资源映射规则是对应的,如果UE使用的时频资源映射规则是频域优先映射规则,则基站所使用的时频资源映射规则也是频域优先映射规则。预设数目个资源单元可以用于映射第二部分上行控制信息,在实际中,可能不仅映射有第二部分上行控制信息,还有可能映射有上行业务数据,预设数目一般可以由技术人员根据经验值,并且存储至基站中,可以是最大可能的第二部分上行控制信息所占用的时频资源的资源单元的个数。
在实施中,基站确定上行业务数据的每个CB分别所占用的时频资源的资源单元的起始位置后,可以获取预设的第二时频资源映射规则,然后根据预设的第二时频资源映射规则和每个CB分别所占用的时频资源的资源单元的起始位置,在分配给UE的时频资源资源中仅除去第一部分上行控制信息所占用的时频资源中,确定出每个CB所占用的时频资源的资源范围(第一个CB所占用的时频资源的资源范围是第一个CB的起始位置至第二个CB对应的起始位置,第二个CB所占用的时频资源的资源范围是第二个CB的起始位置至第三个CB的起始位置等),然后在每个CB所占用的时频资源中分别截去预设数目个资源单元,得到截去预设数目个资源单元后的时频资源,从这些时频资源中恢复每个CB,得到的每个CB,即为上行业务数据。
需要说明的是,上述提到的每个CB所占用的时频资源的资源范围,不是实际每个CB所占用的时频资源,而是UE进行第一次速率匹配后每个CB所占用的时频资源,第一次速率匹配后每个CB所占用的时频资源,在后续会分配一部分给第二部分上行控制信息所使用,所以要在每个CB所占用的时频资源的资源范围中截去预设数目个资源单元,第二次速率匹配后每个CB所占用
的时频资源才是用于映射上行业务数据中的每个CB。在通信中,由于信道编码的特性,即使损失少量编码后的信息,基站也可以完成对编码前的信息的无误解码,所以即使截去的预设数目个资源单元比较多,也可以得到准确无误的上行业务数据。
需要说明的是,上述恢复出上行业务数据并没有对第一部分上行控制信息进行恢复,所以恢复出上行业务数据,并不需要第一部分上行控制信息。
可选的,可以使用每个CB分别占用的时频资源的资源单元的第一数目,计算出每个CB分别占用的时频资源的起始位置,然后基于起始位置,恢复出每个CB,相应的步骤211的处理可以如下:
根据每个CB分别所占用的时频资源的起始位置、以及预设的第二时频资源映射规则,确定每个CB的结束位置,在每个CB的结束位置向前分别对预设数目个资源单元进行截取处理或者比特位置零处理,在截取处理或者比特位置零处理后的时频资源中,恢复每个CB,得到上行业务数据。
在实施中,基站确定出每个CB分别所占用的时频资源的资源单元的起始位置后,使用第一位置,确定分配给UE的时频资源仅除去第一部分上行控制信息所占用的时频资源后的时频资源,即第三时频资源,然后可以获取预设的第二时频资源映射规则,在第三时频资源中,第三时频资源的开始位置即为第一个CB的起始位置,第二个CB的结束位置即为第一个CB的结束位置,第三个CB的起始位置即为第二个CB的结束位置,这样依次确定每个CB分别所占用的时频资源的结束位置,需要说明的是此处对应步骤203的相反过程,确定出的每个CB的结束位置实际上不是真正的结束位置,而是在步骤203中第一次速率匹配后的每个CB的结束位置,在每个CB的结束位置之前的一小部分资源单元映射了第二部分上行控制信息。然后可以从每个CB分别所占用的时频资源的结束位置向前进行截取处理或者比特位置零处理,得到每个CB对应的截取处理或者比特位置零处理后的时频资源,从这些时频资源上恢复CB,即可得到UE上传的上行业务数据。
例如,预设数目为2,确定出结束位置后,对于第一个CB,可以从结束位置向前截取2个资源单元,然后从第3个时频资源开始至第10个时频资源即为第一个CB所占用的时频资源,从该时频资源中恢复CB,得到第一个CB,同理,对于第二个CB,可以从结束位置向前截取2个资源单元,然后从第13个时频资源开始至第25个时频资源即为第二个CB所占用的时频资源,从该
时频资源中恢复CB,得到第二个CB,同理可以恢复到第三个CB和第四个CB,这样,就得到了每个CB,即得到了上行业务数据。
需要说明的是,对于一些数据编码方式来说,编码后头部信息比特相对于尾部信息比特更为重要,所以即使截去尾部也对编码后的数据的影响比较小。
可选的,本公开实施例中,还提供了从时频资源上,恢复第二部分上行控制信息的方法,相应的处理可以如下:
从第一位置,获取第一部分上行控制信息;根据第一部分上行控制信息,确定第二部分上行控制信息所占用的时频资源的资源单元的第二数目;根据每个CB分别所占用的时频资源的起始位置、以及第二数目,从分配给UE的时频资源中,恢复第二部分上行控制信息。
在实施中,如果每个CB的数据量相同,基站可以从第一位置的时频资源上,获取第一部分上行控制信息,然后使用第一部分上行控制信息,确定出第二部分上行控制信息的数据量,使用该数据量,确定出所占用的时频资源的资源单元的第二数目。然后将第二数目除以CB的数目,得到被分为多部分的第二部分上行控制信息分别占用的时频资源的资源单元的数目(后续可以称为第四数目)。然后使用第二个CB的起始位置,向前数第四数目个资源单元,即可得到第二部分上行控制信息中第一部分,所占用的时频资源,采用相同的方法,即可得到第二部分上行控制信息中除最后一部分的第二部分上行控制信息所占用的资源单元,对于最后一部分的上行控制信息,基站可以从分配给UE的时频资源的最后,向前数第四数目个资源单元,即可得到第二部分上行控制信息中最后部分,这样,就得到了第二部分上行控制信息的多个部分占用的时频资源,然后从这些时频资源上,恢复出第二部分上行控制信息。
如果每个CB的数据量不相同,基站可以从第一位置的时频资源上,获取第一部分上行控制信息,然后使用第一部分上行控制信息,确定出第二部分上行控制信息的数据量、以及每个CB所占用的资源单元的第三数目(与步骤205中的处理相同),使用该数据量,确定出所占用的时频资源的资源单元的第二数目。然后使用每个CB所占用的资源单元的第二数目,确定出每个CB的实际结束位置,然后从每个CB的实际结束位置至基站第一次计算得到的结束位置,即为第二部分上行控制信息所占用的时频资源,然后从这些时频资源恢复得到第二部分上行控制信息。
对于本公开实施例,需要说明的是,计算每个CB所占用的时频资源的资源单元的数目的计算公式可以与LTE中的计算公式相同,也可以是使用LTE中的计算公式,推导出直接计算每个CB所占用的时频资源的资源单元的起始位置的计算公式。
本公开实施例中,UE确定分配给本设备的时频资源、以及待传输的上行业务数据和上行控制信息,其中,上行控制信息至少包括第一部分上行控制信息和第二部分上行控制信息,根据预设的第一系统配置和预设的第一时频资源映射规则,在分配给本设备的时频资源中,确定第一部分上行控制信息所占用的时频资源的第一位置,根据预设的第二时频资源映射规则、以及分配给本设备的时频资源中仅除去第一部分上行控制信息所占用的时频资源后的时频资源,确定每个CB分别所占用的时频资源的资源单元的起始位置,根据预设的第二系统配置、以及第二部分上行控制信息,确定第二部分上行控制信息所占用的时频资源的资源单元的第一数目,根据分配给本设备的时频资源中除去第一部分上行控制信息和第二部分上行控制信息所占用的时频资源后的时频资源,确定每个CB分别所占用的时频资源的资源单元的第二数目,根据每个CB分别所占用的时频资源的资源单元的起始位置、每个CB分别所占用的时频资源的资源单元的第二数目、以及预设的第二时频资源映射原则,确定每个CB所占用的时频资源的第二位置,根据第一位置和第二位置,将第一部分上行控制信息、第二部分上行控制信息和每个CB,分别映射至分配给本设备的时频资源中,进行传输。这样,采用上述方法,由于基站可以基于相同的计算方法,确定出每个CB的起始位置,然后恢复出上行业务数据,所以基站恢复出上行业务数据没有依赖第一部分上行信息的内容,所以即使恢复第一部分上行控制信息失败,也可以恢复到上行业务数据,进而可以提高上行业务数据的恢复率,而且由于不需要恢复出第一部分上行控制信息也能恢复出上行业务数据,所以恢复上行业务数据的延时也比较低。
基于相同的技术构思,本公开另一示例性实施例提供了还提供了一种用户设备,如图6所示,该基站包括:
