发射功率状态转化时间的处理方法及装置 技术领域
本公开涉及移动通信网络技术，尤指一种发射功率状态转化时间的处理方法及装置。
背景技术
随着***移动通信技术(4G，the 4th Generation mobile communication technology)长期演进(LTE，Long-Term Evolution)/高级长期演进(LTE-Advance/LTE-A，Long-Term Evolution Advance)***商用的日益完善，对下一代移动通信技术即第五代移动通信技术(5G，the 5th Generation mobile communication technology)的技术指标要求也越来越高。业内普遍认为，5G将支持更高速率(Gbps)、巨量链接(1M/Km2)、超低时延(1ms)、更高的可靠性、百倍的能量效率提升等以支撑新的需求变化。对于5G***中超低时延的指标目前公认的为用户面时延为1ms。
一种有效实现超低时延的方法是通过减少LTE***的发送时间间隔(Transmission Time Interval，简称TTI)，成倍降低单向链路时延，以支持上述1ms空口时延的特性需求。目前存在两种缩小TTI的方法，一种是通过扩大OFDM(Orthogonal frequency-division multiplexing，正交频分复用)***的子载波间隔来缩小单个OFDM符号的时长，该方法在5G的高频通信***和超密集网络中均有涉及；另一种方法是目前3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)所讨论的通过减少单个TTI中OFDM符号的数量来减小TTI长度，例如，将TTI缩短至1～7个OFDM符号或者SC-FDMA(Single-carrier Frequency-Division Multiple Access，单载波频分多址)符号长度，该方法的好处是可以和现有的LTE***完全兼容。
现有LTE***中，终端发射机的发射功率状态转化时间包括发射机功率从关闭状态到开启状态的转化过程(该过程占用时间约为20μs)和发射机功率从开启状态到关闭状态的转化过程(该过程占用时间约为20μs)。随着TTI长度缩短，尤其是TTI等于1个符号即1/14ms时，40μs就会大概占用TTI时间长度的60％。因此，需要提供发射功率转化时间的处理方法适应超低时延场景的需求。

实施例一
本实施例给出了解调参考符号的传输持续时间等于一个符号和数据符号的传输持续时间等于两个符号时，终端的解调参考符号的第一时间模板和数据符号的第二时间模板。
图2(a)为本公开实施例一的解调参考符号的第一时间模板和数据符号的第二时间模板的示意图。如图2(a)所示，本实施例提供的第一时间模板为：终端发射功率第一状态转化时间是在当前解调参考符号开始时刻之前，且发射功率第二状态转化时间设置在当前解调参考符号结束时刻之后。终端以额定发射功率值持续工作的时间等于当前解调参考符号的持续时间间隔。
如图2(a)所示，本实施例提供的第二时间模板为：终端发射功率第一状态转化时间是在当前数据符号的传输持续时间的开始时刻前完成，即在TTI开始时已经达到终端发射机的额定发射功率值，并且该终端发射功率第二状态转化时间是在当前数据符号的传输持续时间结束时才开始功率转化，终端以额定发射功率值持续工作的时间等于当前数据符号的传输持续时间。
根据背景所述，发射功率状态转化时间约为20μs，当解调参考符号为1个符号即1/14ms约为71μs，那么发射功率达到额定值在解调参考符号开始传输前完成，就能节省出20μs的时间用来传送数据，并且发射功率在解调参考符号开始传输后完成第二状态转化，又能节省出20μs的时间。这对于解调参考符号的传输持续时间总长只有71μs的时长来说，是非常大的有效提高数据传输效率的方式。
同样道理，数据符号的发射功率转化时间状态都放在所述数据符号的传输持续时间之外，当前数据符号的传输持续时间的时长都用来传送数据，那么对于数据传输也是非常的有效提高数据传输效率的方式。
图2(a)所示的数据符号的时间模板不仅适设置为2个符号，对于数据符号为1个或3个符号等都是适用的。
如图2(a)所示的第一时间模板和第二时间模板，终端发射功率的功率转化没有占用任何承载数据的时间，能有效提高数据传输效率。
实施例二
本实施例给出了解调参考符号的传输持续时间等于一个符号和数据符号的传输持续时间等于两个符号时，终端的解调参考符号的第一时间模板和数据符号的第二时间模板。图2(b)为本公开实施例二的解调参考符号的第一时间模板和数据符号的第二时间模板的示意图。如图2(b)所示，本实施例的第一时间模板和第二时间模板分别为：
第一时间模板的终端发射功率第一状态转化时间和第二状态转化时间都是在解调参考符号的传输持续时间之外完成；
第二时间模板为：发射功率第一状态转化时间和发射机以额定发射功率持续工作的时间之和等于当前数据符号的传输持续时间，发射功率第二状态转化时间在当前数据符号的传输持续时间结束时刻之后，即在当前数据符号的传输持续时间之后才进行发射功率第二 状态转化。
第二时间模板这样的处理方式可以使得不同数据符号的传输持续时间内发射功率转化过程中产生的干扰存在于每个数据符号的传输持续时间开始处的循环前缀(Cyclic prefix，简称CP)之内，一定程度上能够减少干扰的影响。
实施例三
本实施例给出了解调参考符号的传输持续时间等于一个符号和数据符号的传输持续时间等于两个符号时，终端的解调参考符号的第一时间模板和数据符号的第二时间模板。图2(c)为本公开实施例三的解调参考符号的第一时间模板和数据符号的第二时间模板的示意图。如图2(c)所示，当第一时间模板的终端发射功率第一状态转化时间和第二状态转化时间都是在解调参考符号传输持续时间之外完成时：
第二时间模板为：发射机以额定发射功率持续工作的时间和发射功率第二状态转化时间之和等于当前数据符号的传输持续时间，发射功率第一状态转化时间在当前数据符号的传输持续时间开始前完成，即在数据符号的传输持续时间开始时已经达到终端发射机的额定发射功率值。
第二时间模板这样处理可以降低第一状态转化时间对有效数据承载时间的影响。
实施例四
本实施例给出了解调参考符号的传输持续时间等于一个符号和数据符号的传输持续时间等于两个符号时，终端的解调参考符号的第一时间模板和数据符号的第二时间模板。图2(d)为本公开实施例四的解调参考符号的第一时间模板和数据符号的第二时间模板的示意图。如图2(d)所示，当第一时间模板的终端发射功率第一状态转化时间和第二状态转化时间都是在解调参考符号传输持续时间之外完成时：
第二时间模板为：发射功率第一状态转化时间、发射机以额定发射功率持续工作的时间以及发射功率第二状态转化时间的总和等于所述当前数据符号的传输持续时间。
图2(d)所示的数据符号的第二时间模板可以最大化降低不同数据符号的传输持续时间之间、不同用户之间以及不同信息之间功率上升和/或功率下降的干扰。
实施例五
本实施例给出了解调参考符号的传输持续时间等于一个符号和数据符号的传输持续时间等于两个符号时，终端的解调参考符号的第一时间模板和数据符号的第二时间模板。图2(e)为本公开实施例五的解调参考符号的第一时间模板的示意图。如图2(e)所示，第一时间模板为：终端发射功率第一状态转化时间和以额定发射功率持续工作的时间之和等于当前解调参考符号的传输持续时间，发射功率第二状态转化时间设置在当前解调参考符号传输持续时间结束时刻之后。
第一时间模板这样的处理方式可以使得不同符号内发射功率转化过程中产生的干扰存在于当前符号开始处的循环前缀(Cyclic prefix，简称CP)之内，一定程度上能够减少干扰的影响。
基于第一时间模板的功率转化方式，第二时间模板的发射功率转化方式可以是实施例一到实施例四中的任何一个，请参考实施例一至实施例四中的相关描述，此处不再赘述。
实施例六
本实施例给出了解调参考符号的传输持续时间等于一个符号和数据符号的传输持续时间等于两个符号时，终端的解调参考符号的第一时间模板和数据符号的第二时间模板。图2(f)为本公开实施例六的解调参考符号的第一时间模板的示意图。如图2(f)所示，第一时间模板为：以额定发射功率持续工作的时间和发射功率第二状态转化时间之和等于当前解调参考符号的传输持续时间。发射功率第一状态转化时间在当前解调参考符号的传输持续时间前完成，在解调参考符号的传输持续时间开始时已经达到终端发射机的额定发射功率值。
第一时间模板这样处理可以降低第一状态转化时间对有效数据承载时间的影响。
基于本实施例的第一时间模板的功率转化方式，第二时间模板的功率转化方式可以是实施例一到实施例四中的任何一个，请参考实施例一至实施例四中的相关描述，此处不再赘述。
实施例七

图2(g)所示的解调参考符号的第一时间模板可以最大化降低不同符号之间、不同用户之间以及不同信息之间功率上升和/或功率下降的干扰。
基于本实施例的第一时间模板的功率转化方式，第二时间模板的功率转化方式可以是实施例一到实施例四中的任何一个，请参考实施例一至实施例四中的相关描述，此处不再赘述。
