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。
如果终端设备在第一传输时间间隔内发送的至少一个物理上行共享信道所对应的解调参考信号位于第二传输时间间隔内,终端设备根据所述物理上行共享信道的功率分配值(即所述物理上行共享信道的实际发送功率)确定第二传输时间间隔内各信道的实际发送功率,见本申请实施例步骤100~700说明,可以保证终端设备第二传输时间间隔的最大发送功率按照功率分配优先级顺序有效分配给各上行信道,提高终端设备的上行发送功率效率。
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为本发明功率分配方法流程的实施例,具体包含步骤100~400。
步骤100、获取指示信息,所述指示信息用于指示在第一传输时间间隔内发送至少一个物理上行共享信道、与所述至少一个物理上行共享信道对应的至少一个解调参考信号位于第二传输时间间隔内;
在本实施例中,网络设备通过指示信息指示终端设备在第一传输时间间隔内发送物理上行共享信道,并且,该物理上行共享信道对应的解调参考信号位于第二传输时间间隔内。终端设备发送上行信息的资源由网络设备调度给终端设备。通常,网络设备可以通过发送物理控制信息DCI来调度终端设备发送物理上行共享信道,也可以通过半静态的高层信令配置终端设备在一定的资源发送物理上行共享信道。本发明对于网络设备调度终端设备发送物理上行共享信道的方式不做限定。
传输时间间隔是指无线链路中的一个独立解码传输的长度。在本实施例中,传输时间间隔可以是终端设备发送物理上行共享信道的时间粒度。例如,3GPP TS 36.211V15.1.0协议中,1个无线帧的长度为10ms。一个长度为10ms的无线帧由10个长度为1ms的子帧构成,调度周期的长度为一个子帧的长 度。一个子帧内包含14个时域符号。将一个子帧分割成6个传输时间间隔作为调度的时间单位,可以缩短每次业务传输的时间来达到低时延的要求。对于上行传输,将一个子帧长度包括的14个时域符号按照时间先后顺序划分为6个传输时间间隔,每个传输时间间隔包括的符号个数依次分别是[3,2,2,2,2,3]个符号。
在本实施例中,终端设备根据所述指示信息在所述第一传输时间间隔内发送所述物理上行共享信道,并且所述物理上行共享信道对应的解调参考信号位于第二传输时间间隔内。举例来说,第一传输时间间隔为sTTI#1,第二传输时间间隔为sTTI#2。
步骤200、根据预设的各信道功率分配优先级、所述第一传输时间间隔内各信道的发送功率要求值、所述第一传输时间间隔内的最大发送功率,确定所述物理上行共享信道的功率分配值,即第一功率值;
需要说明的是,步骤200中,根据预设的各信道功率分配优先级、所述第一传输时间间隔内各信道的发送功率要求值、所述第一传输时间间隔内的最大发送功率能够确定所述第一传输时间间隔内各信道的功率分配值(其中包含所述物理上行共享信道的功率分配值);各信道能够以所述功率分配值作为实际发送功率。
各信道的功率分配优先等级是网络设备和终端设备的通信协议预设的。各信道的功率分配优先等级和以下因素中的至少一种相关:各信道所传输的信息中是否包括上行控制信息、各信道所传输的信息中包括的上行控制信息的类型、各信道属于主PUCCH组还是属于辅PUCCH组。
举例来说,在3GPP TS 36.213V15.1.0协议中,功率分配优先等级如下:
P1内有HARQ-ACK的基于符号的sPUSCH/sPUCCH信道>P2内有HARQ-ACK的的基于符号的sPUSCH/sPUCCH信道>P1内有HARQ-ACK的基于时隙的PUSCH/PUCCH信道>P2内有HARQ-ACK的基于时隙的PUSCH/PUCCH信道>P1内有HARQ-ACK的基于子帧的PUSCH/PUCCH 信道>P2内有HARQ-ACK的的基于子帧的PUSCH/PUCCH信道>P1内无HARQ-ACK但有DMRS的基于符号的sPUSCH信道>P2内无HARQ-ACK但有DMRS的基于符号的sPUSCH信道>P1内无HARQ-ACK也无DMRS的基于符号的sPUSCH信道>P2内无HARQ-ACK也无DMRS的基于符号的sPUSCH信道>P1内无HARQ-ACK的基于时隙的sPUSCH信道>P2内无HARQ-ACK的基于时隙的sPUSCH信道>P1内无HARQ-ACK的PUSCH信道>P2内无HARQ-ACK的PUSCH信道。其中,P1代表终端设备的上行小区中主PUCCH组(primary PUCCH group)内的主小区,P2代表终端设备的上行小区中辅PUCCH组(secondary PUCCH group)内的主小区。
所述第一传输时间间隔内各信道的发送功率要求值是预设的,终端设备根据网络设备发送的功率控制命令,确定所述发送功率要求值。例如:终端设备根据网络设备发送的针对第一物理上行共享信道的功率控制命令确定所述第一物理上行共享信道的发送功率要求值为
Figure PCTCN2019071435-appb-000001
再例如,在sTTI#1,除所述第一物理上行共享信道外,终端设备还要发送其他X个信道,其中X≥0。终端设备根据网络设备的功率控制命令确定所述第一物理上行共享信道和该X个信道各自的发送功率要求值。
需要说明的是,根据预设的各信道功率分配优先级、所述第一传输时间间隔内各信道的发送功率要求值、所述第一传输时间间隔内的最大发送功率,确定所述物理上行共享信道的功率分配值的方法,具体包括:终端设备在所述第一传输时间间隔内的最大发送功率优先满足功率分配优先级高的信道,剩余功率不能满足功率分配优先级低的信道时,则等比例降低所述功率分配优先级低的信道功率,使所述剩余功率由所述功率分配优先级低的信道分享。
例如,当sTTI#1内的各信道的发送功率要求值之和大于终端设备在sTTI#1内的最大发送功率时,终端设备根据sTTI#1内待传输的各信道的功率分配优先等级确定各信道的功率分配值,作为实际发送功率。
假设功率分配优先等级A的信道有X0个,功率分配优先等级A-1的信 道有X1个,功率分配优先等级A以及比功率分配优先等级A高的所有信道的发送功率要求值之和小于等于终端设备在sTTI#1的最大发送功率,功率分配优先等级A-1以及比功率分配优先等级A-1高的所有信道的发送功率要求值之和大于终端设备在sTTI#1的最大发送功率,则终端设备确定功率分配优先等级A以及比功率分配优先等级A高的各信道的实际发送功率为根据这些信道的发送功率要求值,确定功率分配优先等级A-1的各信道的实际发送功率为其发送功率要求值的W倍。功率分配优先等级A-2以及功率分配优先等级更低的各信道的实际发送功率为0。其中0≤W≤1,满足功率分配优先等级A-1以及比功率分配优先等级A-1高的所有信道的实际发送功率之和不大于终端设备在sTTI#1的最大发送功率。
步骤300、以所述解调参考信号作为所述第二传输时间间隔内的一个信道、以所述物理上行共享信道的功率分配优先级作为所述解调参考信号的功率分配优先级,结合预设的各信道功率分配优先级、所述第二传输时间间隔内各个信道的发送功率要求值、所述第二传输时间间隔内最大发送功率,确定所述解调参考信号的功率分配值,即第二功率值;
需要说明的是,在步骤300中,将解调参考信号作为所述第二传输时间间隔内的一个信道,结合预设的信道功率分配优先级、所述第二传输时间间隔内各个信道的发送功率要求值、所述第二传输时间间隔内最大发送功率,确定所述第二传输时间间隔内各信道的功率分配值(其中包含所述解调参考信号的功率分配值),各信道能够以所述功率分配值作为实际发送功率。
需要说明的是,将解调参考信号作为所述第二传输时间间隔内的一个信道,结合预设的各信道功率分配优先级、所述第二传输时间间隔内各信道的发送功率要求值、所述第二传输时间间隔内的最大发送功率,确定所述解调参考信号的功率分配值的方法,具体包括:终端设备在所述第二传输时间间隔内的最大发送功率优先满足功率分配优先级高的信道,剩余功率不能满足功率分配优先级低的信道时,则等比例降低所述功率分配优先级低的信道功 率,使所述剩余功率由所述功率分配优先级低的信道分享。
优选地,在步骤300中,所述解调参考信号的功率要求值的取值为:所述物理上行共享信道的功率要求值或功率分配值。
根据本发明的实施例,可以保证第二传输时间间隔内待发送的各上行信道的发送功率满足预设的功率分配优先级等级规则。
例如,根据本实施例,步骤300中功率分配优先等级如下:
P1内有HARQ-ACK的基于符号的sPUSCH/sPUCCH信道=P1内有HARQ-ACK的基于符号的sPUSCH信道的DMRS>P2内有HARQ-ACK的的基于符号的sPUSCH/sPUCCH信道=P2内有HARQ-ACK的基于符号的sPUSCH信道的DMRS>P1内有HARQ-ACK的基于时隙的PUSCH/PUCCH信道>P2内有HARQ-ACK的基于时隙的PUSCH/PUCCH信道>P1内有HARQ-ACK的基于子帧的PUSCH/PUCCH信道>P2内有HARQ-ACK的的基于子帧的PUSCH/PUCCH信道>P1内无HARQ-ACK但有DMRS的基于符号的sPUSCH信道>P2内无HARQ-ACK但有DMRS的基于符号的sPUSCH信道>P1内无HARQ-ACK也无DMRS的基于符号的sPUSCH信道=P1内无HARQ-ACK也无DMRS的基于符号的sPUSCH信道的DMRS>P2内无HARQ-ACK也无DMRS的基于符号的sPUSCH信道=P2内无HARQ-ACK也无DMRS的基于符号的sPUSCH信道的DMRS>P1内无HARQ-ACK的基于时隙的sPUSCH信道>P2内无HARQ-ACK的基于时隙的sPUSCH信道>P1内无HARQ-ACK的PUSCH信道>P2内无HARQ-ACK的PUSCH信道。其中,P1代表终端设备的上行小区中主PUCCH组(primary PUCCH group)内的主小区,P2代表终端设备的上行小区中辅PUCCH组(secondary PUCCH group)内的主小区。
例如,在sTTI#2内,除物理上行共享信道对应的DMRS外,终端设备可能还需要发送其他Y个信道,终端设备首先根据网络设备的功率控制命令确定该Y个信道各自的发送功率要求值,并将物理上行共享信道的功率要求 值或功率分配值作为与物理上行共享信道对应的DMRS的功率要求值。
如果在sTTI#2内,与所述物理上行共享信道对应的DMRS的功率要求值和其他信道的功率要求值之和大于终端设备在sTTI#2的最大发送功率,终端设备设定解调参考信号功率分配优先级,结合预设的其他Y个信道信道的功率分配优先等级确定所述解调参考信号功率分配值。
如果有Y 1个信道的功率分配优先等级大于所述物理上行共享信道的功率分配优先级、有Y 2个信道的功率分配优先等级小于所述物理上行共享信道的功率分配优先级,终端设备将sTTI#2最大发送功率依次优先分配给该Y 1个信道、物理上行共享信道对应的DMRS和该Y 2个信道,可依次保证功率分配优先级较高的Y 1个信道、物理上行共享信道和功率分配优先级较低的Y 2个信道的性能,满足系统传输效率要求(其中Y、Y 1、Y 2均为≥0的整数)。
需要说明的是,在前述步骤200~300中,终端设备确定出物理上行共享信道的发送功率为第一功率P 1,物理上行共享信道对应的解调参考信号的功率分配值为第二功率P 2。终端设备发送的物理上行共享信道中的信息可能使用高阶调制阶数,例如16QAM,64QAM等。如果物理上行共享信道的发送功率和与其对应的DMRS的发送功率不同,或者差异过大,网络设备根据DMRS估计的信道状态用于解调物理上行共享信道中的信息时可能出现判决错误。
步骤400、根据第一功率值P 1和第二功率值P 2确定所述第二传输时间间隔内解调参考信号的实际发送功率,具体包括以下步骤:
步骤401、如果所述第一功率值和所述第二功率值的差别在预设门限值内或所述第二功率值大于等于所述第一功率值,则以所述第一功率值±预设门限值delta范围内的值作为所述解调参考信号的实际发送功率。
例如,如果P 2>P 1,则终端设备用[P 1-dela,P 1+delta]中的一个功率值发送所述解调参考信号,可在一定程度上保证网络设备正确解调物理上行共享信道。
再例如,如果P 2<P 1且P 1-P 2<delta,终端设备用[P 1-delta,P 1+delta]中的一个功率值发送所述解调参考信号,仍可在一定程度上保证网络设备正确解调物理上行共享信道。
步骤402、如果所述第一功率值和所述第二功率值的差别在预设门限值外且第二功率值小于所述第一功率值,所述解调参考信号的实际发送功率为0。
例如,如果P 2<P 1且P 1-P 2>delta,则终端设备丢弃所述解调参考信号。
需要说明的是,在解调参考信号的功率分配值P 2小于物理上行共享信道的发送功率P 1,而且差值大于预设的门限时,网络设备根据解调参考信号估计的信道状态用于解调所述物理上行共享信道中的信息时可能出现判决错误,此时,网络设备难以正确解调物理上行共享信道。这种情况下,终端设备发送DMRS的意义不大,丢弃DMRS可提高终端设备的发送功率效率。
作为一个实施例,所述预设门限值也可设为0。此时,如果解调参考信号的功率分配值(即第二功率值P 2)小于所述物理上行共享信道的功率分配值(即第一功率值P 1),终端设备丢弃所述解调参考信号。
需要说明的是,如果在解调参考信号的功率分配值P 2小于物理上行共享信道的发送功率P 1的情况下,网络设备难以正确解调物理上行共享信道,但终端设备在所述第二传输时间间隔内又需要把可用的最大发送功率分配给优先级更高的其他Y 1个信道。这种情况下,终端设备发送DMRS的意义不大,丢弃DMRS可提高终端设备的发送功率效率。
在步骤401中,优选地,所述第一功率值±预设门限值范围内的值作为所述解调参考信号的实际发送功率的步骤中,进一步包含:如果所述第二功率值大于等于所述第一功率值,则以所述第一功率值作为所述解调参考信号的实际发送功率。
例如,如果P 2>P 1则终端设备用第一功率P 1发送所述解调参考信号,可 在一定程度上保证网络设备正确解调物理上行共享信道。
在步骤401中,优选地,所述第一功率值±预设门限值范围内的值作为所述解调参考信号的实际发送功率的步骤中,进一步包含:如果所述第二功率值小于所述第一功率值,则以所述第二功率值作为所述解调参考信号的实际发送功率。
例如,如果P 2<P 1且P 1-P 2≤delta,则终端设备用P 2发送所述解调参考信号,仍可在一定程度上保证网络设备正确解调物理上行共享信道。
图2为本发明功率分配方法流程的另一实施例,具体包含步骤100~200、500~600。
步骤100、获取指示信息,所述指示信息用于指示在第一传输时间间隔内发送至少一个物理上行共享信道、与所述至少一个物理上行共享信道对应的至少一个解调参考信号位于第二传输时间间隔内;
步骤200、根据预设的各信道功率分配优先级、所述第一传输时间间隔内各信道的发送功率要求值、所述第一传输时间间隔内的最大发送功率,确定所述物理上行共享信道的功率分配值,即第一功率值;
步骤500、以所述第一功率值±预设门限值delta范围内的值作为所述解调参考信号的功率分配值,即第二功率值;
例如,直接根据所述物理上行共享信道的功率分配值确定所述解调参考信号的功率分配值,即第二功率值=第一功率值。
步骤600、以所述第二功率值作为所述解调参考信号的实际发送功率。
进一步地,图1~2所示的任意一个实施例中,以所述第一功率或第二功率值作为所述解调参考信号的实际发送功率,还可以进一步包含以下步骤:
步骤700、所述第二时间段内除所述解调参考信号外的其他信道的实际发送功率之和不超过剩余功率,所述剩余功率是所述第二传输时间间隔内最大发送功率与所述解调参考信号的实际发送功率的差。
因此结合图1~2,进一步优化的实施例实施例可以包含步骤100、200、 300、400、700。进一步优化的实施例也可以包含步骤100、200、500、600、700。
图3为物理上行共享信道和对应的解调参考信号位置的示意图。具体地在本发明各实施例所述步骤100~700中,所述第一传输时间间隔在先,所述第二传输时间间隔在后。图3中所示物理上行共享信道特指“第一”,因为在第一传输时间间隔内除第一物理上行共享信道外,还可能有其他物理上行共享信道。例如,如果为终端的设备配置的上行小区分为两个小区组。在一个sTTI内,终端设备可能在每个小区组中主小区和辅小区都发送sPUSCH。这些不同的物理上行共享信道的优先级可能是不一样的,因为信道的功率分配优先等级和以下因素中的至少一种相关:信道所传输的信息中是否包括上行控制信息、信道所传输的信息中包括的上行控制信息的类型、信道属于主PUCCH组还是属于辅PUCCH组。图3中DMRS即对应于所述解调参考信号。
图4为LTE演进版本中物理上行共享信道和对应的解调参考信号不在同一传输时间间隔的应用示情形意图。将一个子帧长度包括的14个时域符号按照时间先后顺序划分为6个传输时间间隔sTTI#0~#5,图中“os”表示时域符号,sTTI#0~#5包括的符号个数依次分别是[3,2,2,2,2,3]个符号。
具体地,本发明方法应用于3GPP TS 36.211V15.1.0协议,sTTI内可以传输短物理上行共享信道(sPUSCH)。sPUSCH可以承载上行共享信道UL-SCH和/或上行控制信息(UCI)。为了在网络设备侧解调sPUSCH的信息,每个sPUSCH都有与其对应的解调参考信号DMRS,用于估计sPUSCH所经历的信道状况。用于解调sPUSCH的DMRS的位置是通过调度sPUSCH的指示信息发送给终端设备的。在一个sTTI内,终端设备可能需要发送多个上行信道。例如,如果为终端设备配置的上行小区分为两个小区组。在一个sTTI内,终端设备可能在每个小区组中主小区发送sPUSCH和或短物理上行控制信道sPUCCH。在每个小区组中各辅小区发送sPUSCH。
网络设备调度sPUSCH的指示信息(DCI)中有专门的DMRS类型字段来指示sTTI中DMRS的位置,如下表所示:
Figure PCTCN2019071435-appb-000002
举例来说,如果调度sTTI#0的DCI中的DMRS类型字段取值为“00”,则代表sTTI#0内传输的sPUSCH对应的DMRS位于符号0;如果sTTI#0的DCI中的DMRS类型字段取值为“01”,则代表sTTI#0内传输的sPUSCH对应的DMRS位于符号2。
根据上表,有时sPUSCH和对应的DMRS不在相同的sTTI内。例如调度sTTI#1的DCI中的DMRS类型字段取值为“11”时,该sPUSCH所对应的DMRS位于符号5,即位于sTTI#2内。
如果终端设备sTTI#1内待传输的所有上行信道的功率要求值之和大于终端设备在该sTTI#1的最大发送功率,则终端设备需要通过预设的各信道的优先级等级确定各信道的实际发送功率。根据该预设的各信道的功率优先等级,终端设备优先满足功率优先等级要求高的信道的发送功率。
如果终端设备在sTTI#1内发送的至少一个物理上行共享信道所对应的解调参考信号位于sTTI#2内,终端设备根据所述物理上行共享信道的功率分配值确定sTTI#2内各信道的实际发送功率,可以保证终端设备sTTI#2的最大发送功率按照功率分配优先级顺序有效分配给各上行信道,提高终端设备的上行发送功率效率。
本发明还提出一种移动通信设备,用于本申请任意一项实施例所述方法, 包含网络设备和至少一个终端设备;

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。
