Description

一种数据传输方法及通信设备
本申请要求于2017年05月31日提交中国专利局，申请号为201710402011.6，发明名称为“一种信号的发射方法及通信设备”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
本发明涉及通信领域，尤其涉及一种数据传输方法及通信设备。
背景技术
随着无线通信数据流量的日益增加，传统的sub6G频谱日趋紧张，因此在第5代通信***新空口(5th generation new radio，缩写：5G NR)中，会使用较高的频段，如15GHz、28GHz、38GHz、60GHz、70GHz等。高频信号失真率小，既有较强的可恢复性，且抗干扰率强的优点，但是高频信号与低频不同，高频信号的路径损耗非常大，因此覆盖距离受限。
为了增加高频信号的覆盖，降低正确解调需要的(Signal Noise Ratio)SNR，长期演进(long term evolution，缩写：LTE)***中针对物理上行共享信道(physical uplink shared channel，缩写：PUSCH)提出了传输时间间隔绑定(transmission time interval，缩写：TTI Bundling)技术。LTE中物理层调度的基本单位是1ms，然而在某些小区边缘，覆盖受限的情况下，用户设备由于受到其本身发射功率的限制，在1ms的时间间隔内，可能无法满足数据发送的误块率(BLER)要求。所以TTI Bundling将一个数据包在连续多个传输时间间隔(TTI)资源上重复进行传输，接收端将多个TTI资源上的数据合并以达到提高传输质量的目的，从而可以克服边缘覆盖受限的情况。
但是由于TTI Bundling需要在多个子帧重复发射数据，会拉长正确解调的时间，增加了时延，应用性差，例如，很多实时性要求高的场景(如自动驾驶)无法适用，不符合5G NR中低时延的需求。
发明内容
本发明实施例提供了一种数据传输方法及通信设备，用于提高覆盖，尤其是可以增加高频信号的覆盖。该数据传输方法应用于通信设备，在一种实现方式中，通信设备为基站，在另一种实现方式中，该通信设备也可以为用户设备。

在一种可能的实现方式中，第一通信设备生成传输模式指令之后，第一通信设备将传输模式指令向第二通信设备发送，传输模式指令用于指示采用频域重复模式传输数据，具体的，1、第一通信设备向第二通信设备发送传输模式指令，该传输模式指令指示该第一通信设备将采用频域重复模式向第二通信设备发送数据，以通知第二通信设备采用对应的方式接收数据。2、该传输模式指令用于指示第二通信设备采用频域重复模式向第一通信设备发送数据，第一通信设备可以动态的向第二通信设备发送传输模式指令，也就是说，当第一通信设备检测到当前信道质量较差时，就可以通知第二通信设备采用频域重复模式发送数据，增强了实时性；第一通信设备还可以通过半静态信令发送该传输模式指令，也就是说，当第一通信设备向第二通信设备发送传输模式指令后，对第二通信设备进行配置，第一通信设备可以周期性的指示第二通信设备采用频域重复模式发送数据，减小了信令开销。
在一种可能的实现方式中，当第一通信设备需要向第二通信设备发送数据时，第一通信设备判断是否采用频域重复模式发送数据的具体方式包括：第一通信设备根据参考信号的测量值；和/或，根据信道质量指示CQI信息，和/或，根据调制与编码策略MCS信息中的至少一种信息来判定是否按照频域重复模式传输数据。
在一种可能的实现方式中，传输模式指令包括指示标识，频域重复模式包括至少两种重复方式，指示标识与重复方式具有对应的映射关系，第一通信设备根据传输模式指令确定频域重复模式具体可以包括：第一通信设备根据传输模式中的指示标识及映射关系确定频域重复模式的重复方式；重复倍数(如2倍重复，4倍重复等)；以及每一份重复的数据块内资源调度的连续映射情况，如连续资源映射或非连续资源映射等；该频域重复模式的重复方式可以采用重复数据块的资源映射图样的形式存在。本发明实施例中，第一通信设备和第二通信设备可以具体约定频域重复模式的重复方式，第一通信设备根据传输模式中的指示标识及映射关系确定频域重复模式的重复方式，第一通信设备可以根据当前的信道情况来确定具体的重复方式，以使得解调性能最优。

请参阅图3所示，本发明实施例中提供了一种数据传输方法的一个实施例包括：
在本实施例中，第一通信设备以用户设备，第二通信设备以基站为例进行说明，本实施例中以高频的单小区的应用场景为例，用户设备在高频小区以频域重复模式向基站发送上行数据。
步骤301、用户设备获取传输模式指令，传输模式指令用于指示用户设备采用频域重复模式发送数据，频域重复模式为在不同的频域资源上重复发送相同的数据。
用户设备获取传输模式指令的方式包括两种：1、接收基站发送；2、用户设备生成。
在第一种可能实现方式中，该传输模式指令是由基站生成的，然后基站将该传输模式发送给该用户设备，基站通过物理下行控制信道(physical downlink control channel，缩写：PDCCH)或半静态信令发送该传输模式指令，该传输模式指用于指示用户设备采用频域重复模式来发送数据。基站决定采用频域重复模式的判断方法至少包含以下方式中的一种：
1、根据参考信号的测量值判定是否指示用户设备按照频域重复的模式发送数据。例如，基站可以根据信道探测参考信号(Sounding Reference Signal，缩写：SRS)或上行DMRS测量的RSRP等测量值判定是否触发用户设备按照频域重复的模式发送数据。如当上行DMRS测量的RSRP测量值超过预设范围时，则判定需要出发用户设备按照频域重复模式发送数据，可以理解的是，当通过参考信号的测量值可以确定当前信道质量较差，则生成传输模式指令，将该传输模式指令发送给用户设备，需要触发用户设备按照域重复的模式发送数据，以提高覆盖。
2、根据信道质量指示CQI信息判定是否指示用户设备按照频域重复的模式发送数据。如，CQI的值大于预置值，则基站生成传输模式指令，将该传输模式指令发送给用户设备触发用户设备按照频域重复的模式发送数据。
3、根据调制与编码策略(Modulation and Coding Scheme，缩写：MCS)信息判定是否指示用户设备按照频域重复的模式发送数据。调制与编码策略主要实现射频速率的配置，由于物理速率依赖于调制方法、编码率和空间流数量等多个因素，MCS可以理解为这些影响速率因素的完整组合，每种组合用整数来唯一标示，每一个MCS索引其实对应了一组参数下的物理传输速率。
基站可以根据上行PUSCH的MCS信息判定是否触发用户设备按照频域重复的模式发送数据。如，若该MCS信息超过预置范围，则表明该物理传输速率较低，则基站判定触发用户设 备按照频域重复的模式发送数据。
需要说明的是，对于上述基站判断是否指示用户设备采用频域重复模式发送上行数据的具体方式指示举例说明，并不造成对本发明的限定说明。
基站动态的向用户设备发送传输模式指令，也就是说，当基站检测到当前信道质量较差时，就可以通知用户设备采用频域重复模式发送数据，增强了实时性。
基站通过半静态信令发送该传输模式指令，也就是说，当基站向用户设备发送传输模式指令后，对用户设备进行配置，基站可以周期性的指示用户设备采用频域重复模式发送数据，减小了信令开销。本发明实施例中对于基站向用户设备发送传输模式指令的具体方式并不限定。
在第二种可能实现方式中，该传输模式指令是由用户设备生成的，也就是说，该用户设备可以确定是否按照频域重复模式向基站发送数据。
具体的，用户设备决定是否采用频域重复模式的判断方法至少包括如下一种方式：
1、根据信道状态信息参考信号(CSI-RS)或下行DMRS测量的RSRP等测量值判定是否触发用户设备按照频域重复的模式发送数据。
2、根据用户设备反馈的CQI/RI等信息判定是否触发用户设备按照频域重复的模式发送数据。
3、用户设备可以根据上行PUSCH的MCS信息判定是否触发用户设备按照频域重复的模式发送数据。
在此种方式中，当用户设备确定了需要按照频域重复模式向基站发送数据后，用户设备需要动态或半静态向基站发送消息，该消息用于通知基站，用户设备准备按照频域重复模式向基站发送数据。
步骤302、用户设备根据传输模式指令确定频域重复模式。
用户设备根据该传输模式指令确定需要按照频域重复模式向基站发送数据。
进一步的，该传输模式指令包括指示标识，频域重复模式包括至少两种重复方式，指示标识与重复方式具有对应的映射关系，该用户设备根据传输模式中的指示标识及映射关系确定频域重复模式的重复方式。
该频域重复模式的重复方式具体可以包括：重复倍数(如2倍重复，4倍重复等)；以及每一份重复的数据块内资源调度的连续映射情况，如连续资源映射或非连续资源映射等。请参阅图4和图5进行理解，图4为频域重复数据块的连续资源映射示意图，图5为频域重复数据块的非连续资源映射示意图。在图4和图5中，数列的单元格为不同的频域资源，不同形状的标记用于标识数据块，本实施例中以2倍重复为例进行说明，从图4中可以看出，相同的数据块在不同的频域资源上重复发送，但是相同的数据块在频域资源上是连续映射。在图5中可以看出，相同的数据块在不同的频域资源上重复发送，但是相同的数据块在频域资源上并不是连续映射。需要说明的是，例如，该频域重复模式的重复方式可以采用重复数据块的资源映射图样的形式存在。
本发明实施例中，例如，指示标识可以包括：“1”、“2”、“3”，例如，该“1”表示：2倍重复，且连续映射方式；而“2”表示：4倍重复，且非连续映射方式等等。再 如，指示标识可以包括两类，一类用于表示重复倍数(如“1”、“2”)的第一标识，另一类用于表示映射方式(如“a”、“b”)的第二标识，该第一标识包括的数值与第二标识包括的数值的组合共同表示不同的重复方式，当然，也可以通过一类标识来表示重复方式。
例如，若该指示标识为“1”则表示：2倍重复。
若该标识包括“1”和“a”表示：2倍重复，且连续映射等等。
需要说明的是，对于频域重复模式，及该频域重复模式包括的重复方式用户设备和基站通过协议预先约定。上述对于指示标识只是为了方便说明而举的例子，并不造成对本发明的限定性说明。
本发明实施例中，第一通信设备和第二通信设备可以具体约定频域重复模式的重复方式，第一通信设备根据所述传输模式中的指示标识及所述映射关系确定所述频域重复模式的重复方式，第一通信设备可以根据当前的信道情况来确定具体的重复方式，以使得解调性能最优。
步骤303、用户设备向基站发送第一指示消息，该第一指示消息用于指示用户设备将要按照频域重复模式发射数据。
可选的，在一种实现方式中，若步骤301中的传输模式指令是由基站发送给用户设备的，用户设备也可以不执行步骤303，而直接执行步骤304。
步骤304、用户设备按照频域重复模式向基站发送数据。
用户设备按照频域重复模式向基站发送上行数据。
进一步的，用户设备可以按照指示标识确定具体的重复方式向基站发送上行数据。
需要说明的是，对于用户设备侧有多天线发射的***，用户设备可以对不同频域重复块的数据，采用不同的动态预编码或PMI码本加权发射，以更好的匹配不同频带的信道，提高解调性能。
步骤305、基站按照频域重复模式，对数据进行联合解调数据，得到解调后的数据。
基站按照频域重复模式，或，按照频域资源模式的具体的重复方式，抽取多个重复的数据块合并接收，合并各个重复的资源块做联合的多进多出(multiple-input multiple-output，缩写：MIMO)均衡，之后进行解调和信道译码等，联合解调该数据，得到解调后的数据。
本发明实施例中，基站可以指示用户设备按照频域重复模式发送上行数据，或者，用户设备自身也可以确定按照频域重复模式来发送上行数据。然后，用户设备以频域重复的模式发送数据，可以提高PUSCH信道的解调性能，提升***覆盖距离。具体地，2倍重复发射可以获得2～4dB的覆盖提升，4倍重复发射可以获得5～8dB的覆盖提升。

基站获取传输模式指令的方式包括两种：1、基站生成；2、用户设备发送的。

2、根据信道质量指示CQI信息判定是否指示用户设备按照频域重复的模式发送数据。
3、根据调制与编码策略(Modulation and Coding Scheme，缩写：MCS)信息判定是否指示用户设备按照频域重复的模式发送数据。
基站可以根据下行PUSCH的MCS信息判定是否触发用户设备按照频域重复的模式发送数据。
需要说明的是，对于上述基站判断是否指示用户设备采用频域重复模式发送上行数据的具体方式指示举例说明，并不造成对本发明的限定说明。
在第二种可能实现方式中，该传输模式指令是由用户设备发送的，也就是说，该用户设备可以确定指示基站按照频域重复模式向基站发送数据。
具体的，用户设备决定是否采用频域重复模式的判断方法至少包括如下一种方式：
1、用户设备根据CSI-RS或下行DMRS测量的RSRP等测量值判定是否触发基站按照频域重复的模式发送数据。
2、用户设备可以根据下行PDSCH的MCS信息判定是否触发用户设备按照频域重复的模式发送数据。
在此种方式中，当用户设备确定了需要按照频域重复模式传输数据，然后，该用户设备向基站发送消息，用户设备需要动态或半静态向基站发送消息，该消息用于通知基站，基站需要按照频域重复模式向用户设备发送下行数据。
步骤602、基站根据传输模式指令确定频域重复模式。
基站根据该传输模式指令确定需要按照频域重复模式向用户设备发送下行数据。
进一步的，该传输模式指令包括指示标识，频域重复模式包括至少两种重复方式，指示标识与重复方式具有对应的映射关系，该基站根据传输模式中的指示标识及映射关系确定频域重复模式的重复方式。
该频域重复模式的重复方式具体可以包括：重复倍数(如2倍重复，4倍重复等)；以及每一份重复的数据块内资源调度的连续映射情况，如连续资源映射或非连续资源映射等。请参阅图4和图5进行理解，连续资源映射和非连续资源映射。
步骤603、基站向用户设备发送第二指示消息，该第二指示消息用于指示基站将要按照频域重复模式发射数据。
可选的，在一种实现方式中，若步骤601中的传输模式指令是由用户设备发送给基站的，基站也可以不执行步骤603，而直接执行步骤604。
步骤604、基站按照频域重复模式与用户设备进行数据传输。
基站按照频域重复模式向用户设备发送下行数据。
进一步的，基站可以按照指示标识确定具体的重复方式向用户设备发送下行数据。
需要说明的是，对于基站侧有多天线发射的***，基站可以对不同频域重复块的数据，采用不同的动态预编码或PMI码本加权发射，以更好的匹配不同频带的信道，提高解调性能。
步骤605、用户设备按照频域重复模式，进行联合解调数据，得到基站发送的解调后的数据。
用户设备按照频域重复模式，或，按照频域资源模式的具体的重复方式，抽取多个重复的数据块合并接收，合并各个重复的资源块做联合的多进多出(multiple-input multiple-output，缩写：MIMO)均衡，之后进行解调和信道译码等，联合解调该数据，得到基站发送的解调后的数据。
本发明实施例中，基站可以自身确定将按照频域重复模式发送下行数据，或者，基站也可以接收用户设备发送的传输模式指令，基站根据接收到的传输模式指令确定将按照频域重复模式来发送下行数据。然后，基站以频域重复的模式发送数据，可以提高下行信道的解调性能，提升***覆盖距离。
