Description

最大配置输出功率的报告方法和终端设备 技术领域
本发明涉及通信领域 ，特别涉及一种最大配置输出功率的报告方法 和终端设备。 背景技术
在长期演进LTE , Long Term Evolution)系统中， 为使基站对终端设 备指示适当的发射功率控制命令， 给该终端设备调度合适的调制编码方 式和带宽， 该终端设备需要测量其功率剩余量 （PH: Power Headroom) 并将该 PH报告基站。 其中， 功率剩余量 PH为终端设备的最大配置输出 功率 (； PCMAX : Configured Maximum Output Power)与当时的发射功率的差值。
在 LTE系统中， 由于在终端设备发送上行数据时使用的实际的最大 配置输出功率与基站侧估计的终端设备使用的最大配置输出功率的误差 范围较小， 因此，在功率剩余量报告（PHR: Power Headroom Report )中， 终端设备只需要报告功率剩余量， 而最大配置输出功率由基站自己估计。
在增强的长期演进 (LTE-A: LTE-Advanced)系统中， 由于采用了载波 聚合技术， 当终端设备在多个服务小区 （Serving Cell ) 上同时进行上行 数据传输时， 如果仍然依靠基站来估计终端设备使用的最大配置输出功 率， 那么该基站估计得到的最大配置输出功率将与终端设备实际使用的 最大配置输出功率之间存在较大的偏差， 这样会影响基站对终端设备的 资源调度。
目前， 在 LTE-A系统中， 为了避免上述的影响， 当终端设备上报功 率剩余量报告 PHR时， 除了向基站上报功率剩余量外， 在具备一定条件 下还需要上报最大配置输出功率 PCMAX。
其中， 当终端设备配置了多个服务小区时， 如果该终端设备触发了 功率剩余量报告 PHR并且基站分配给该终端设备的上行资源可以容纳该 功率剩余量报告 PHR, 该终端设备将同时上报所有处于激活状态的且配 置有上行载波的服务小区上的功率剩余量； 而根据协议规定终端设备仅 上报具有有效的上行授权 （Valid UL grant) 的服务小区对应的最大配置 输出功率 P™ax。 对于没有上行授权的服务小区， 为了计算得到该服务小 区上的功率剩余量， 协议中定义了计算功率剩余量需要用的参数的参考 值， 根据协议中定义的参考值， 基站可以准确的计算出该终端设备在每 个没有上行授权的服务小区上使用的最大配置输出功率 pCMAX。
但是在实现本发明的过程中发明人发现现有技术中存在如下问题： 当终端设备在至少一个服务小区上没有有效的上行授权， 但在该服务小 区上却有实际的物理传输， 如上行非自适应重传或基站仅调度信道状态 信息时，该终端设备不能上报该服务小区对应的最大配置传输功率 pCMAX。 但是， 该终端设备在该服务小区上将有实际的最大配置输出功率 PCMAX , 在这种情况下， 若基站根据协议中定义的参考值计算该终端设备在该服 务小区上的最大配置传输功率 PCMAX , 则计算获得的最大配置传输功率 PCMAX与实际的最大配置输出功率之间会存在较大误差， 这样， 将影响该 基站后续在该服务小区上对该终端设备的发射功率的控制以及对其调制 编码方式的确定和带宽调度， 目前还没有解决上述问题的有效方法。
应该注意， 上面对技术背景的介绍只是为了方便对本发明的技术方 案进行清楚、 完整的说明， 并方便本领域技术人员的理解而阐述的。 不 能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技 术方案为本领域技术人员所公知。 发明内容
本发明实施例的目的在于提供一种最大配置输出功率的报告方法和 终端设备， 通过该方法使得终端设备在一个服务小区上有实际的物理传 输， 如上行非自适应重传或基站仅调度信道状态信息时， 能够上报该服 务小区对应的最大配置输出功率的值， 解决了现有技术中存在的问题。
根据本发明实施例的一个方面提供了一种最大配置输出功率的报告 方法， 该方法包括：
在当前子帧上终端设备在触发功率剩余量报告、 且基站为该终端设 备分配了用于在上行共享信道上传输新数据的上行授权， 且该上行授权 能够容纳该功率剩余量报告时， 该终端设备依次判断在每个服务小区上 是否有上行数据的非自适应重传； 或者判断在每个服务小区上基站是否 只调度了信道状态信息， 而没有分配上行授权来传输上行共享信道的数据; 若判断结果为是， 则该终端设备获得存在该上行数据的非自适应重 传、 或者存在只调度了信道状态信息， 而没有分配上行授权来传输上行 共享信道的数据的服务小区对应的最大配置输出功率；
将获得的该最大配置输出功率向该基站报告。
根据本发明实施例的另一个方面提供了一种终端设备， 该终端设备 包括：

根据本发明实施例的另一个方面提供了一种存储有计算机可读程序 的存储介质， 其中该计算机可读程序使得计算机在终端设备中执行上述 最大配置输出功率的报告方法。

从以下结合附图的详细描述中，本发明实施例的上述以及其他目的、 特征和优点将变得更加显而易见， 在附图中：
图 1A和图 1B是当前上报最大配置输出功率的两种场景示意图； 图 2是本发明实施例 1的最大配置输出功率的报告方法流程图； 图 3是本发明实施例 2的最大配置输出功率的报告方法流程图； 图 4是本发明实施例 3的最大配置输出功率的报告方法流程图； 图 5是作为终端设备的示例使用的移动电话的示意图；
图 6是本发明实施例 4的终端设备的构成示意图；
图 7是本发明实施例 5的终端设备的构成示意图。 具体实施方式
下面结合附图对本发明的各种实施方式进行说明。 这些实施方式只 是示例性的， 不是对本发明的限制。 为了使本领域的技术人员能够容易 地理解本发明的原理和实施方式， 本发明的实施方式以 LTE-A系统的最 大配置输出功率的报告为例进行说明， 但可以理解， 本发明并不限于上 目前在终端设备触发了功率剩余量报告、 并且基站分配给终端设备 的用于传输新数据的上行授权且该上行授权能够容纳该功率剩余量报告
PHR 时， 根据目前协议规定对于每个处于激活状态且配置有上行载波的 服务小区 （Serving Cell) , 如果在上述服务小区上终端设备获得了有效的 上行授权 （Valid UL grant) , 那么该终端设备报告计算该功率剩余量 PH 所用的最大配置输出功率。 然而， 目前在一个服务小区上没有有效的上 行授权， 但有实际的物理传输， 如上行非自适应重传或基站仅调度信道 状态信息， 需要终端设备实际的最大配置输出功率时， 该终端设备不能 够上报该最大配置输出功率 Ρ™ΛΧ。 在这种情况下， 如果基站根据协议中 定义的参考值来计算终端设备在服务小区上的最大配置传输功率 PCMAX， 那么由于实际和计算的最大配置输出功率 PCMAX之间会存在较大误差， 将 会影响基站后续在服务小区上对该终端设备的发射功率的控制以及对其 调制编码方式的确定和带宽调度。
图 1A是当前上报最大配置输出功率的场景一的示意图。以两个服务 小区 Serving Celll和 Serving Cell2为例进行说明。如图 1A所示， 在终端 设备触发了功率剩余量报告 PHR、 并且基站分配给终端设备的用于在上 行共享信道上传输新数据的上行授权且该上行授权能够容纳该功率剩余 量报告时， 终端设备在处于激活状态且配置有上行载波的服务小区 2上 没有有效的上行授权， 但在服务小区 2 上有上行数据的非自适应重传 (non-adaptive retransmission) ,根据目前协议该终端设备不能上报服务小 区 2的最大配置传输功率 PCMAX，只上报服务小区 1的最大配置传输功率 PCMAX。
图 1B是当前上报最大配置输出功率的场景二的示意图。 如图 1B所 示， 在终端设备触发了功率剩余量报告、 并且基站分配给终端设备的用 于在上行共享信道上传输新数据的上行授权且该上行授权能够容纳该功 率剩余量报告时， 终端设备在处于激活状态且配置有上行载波的服务小 区 2上没有有效的上行授权， 仅传输信道状态信息 (CSI ： Channel status information) , 而没有来自上行共享传输信道 (UL-SCH ： Uplink Share Channel)的数据，根据目前协议该终端设备不能上报服务小区 2的最大配 置传输功率 Ρ™ΛΧ， 只上报服务小区 1的最大配置传输功率 PCMAX。
其中， 该有效的上行授权是指基站为终端设备分配的用于在上行共 享信道上传输数据 （传输新数据或自适应重传的数据） 的授权。 如在图
1A和图 1B所示的两种场景下， 在 103和 10 中， 基站为服务小区 1 分配用于新数据上传的上行授权， 但在服务小区 2上没有， 因此， 根据 目前协议终端不能上报服务小区 2的最大配置传输功率 PCMAX。
但是在图 1 A和图 1B所示的上述两种情况下， 终端设备在服务小区 2 上将有实际的最大配置输出功率 P™ax， 在这种情况下， 如果基站根据协 议中定义的参考值来计算终端设备在服务小区 2上的最大配置传输功率
ΡθΜΛΧ , 那么由于实际的和计算的最大配置输出功率 PCMAX两者之间会存在 较大误差， 因此将影响基站后续在服务小区 2上对该终端设备的发射功 率的控制以及对其调制编码方式的确定和带宽调度。 因此针对上述问题， 本发明实施例提供了一种最大配置输出功率的报告方法和终端设备。 以 下以上述两种场景为例进行说明。
图 3是本发明实施例 1 的最大配置输出功率的报告方法流程图。 如 图 3所示， 该方法包括：
歩骤 201， 在当前子帧上终端设备在触发功率剩余量报告 PHR、 且 基站为该终端设备分配了用于在上行共享信道上传输新数据的上行授 权， 且该上行授权能够容纳该功率剩余量报告时， 该终端设备依次判断 在每个服务小区上是否有上行数据的非自适应重传；
歩骤 202，若判断结果为是，则该终端设备获得存在该上行数据的非 自适应重传的服务小区对应的最大配置输出功率 PCMAX;
歩骤 203， 将获得的该最大配置输出功率 PCMAX向该基站报告。
图 4是本发明实施例 2的最大配置输出功率的报告方法流程图。 如 图 4所示， 该方法包括：
歩骤 301， 在当前子帧上终端设备在触发功率剩余量报告 PHR、 且 基站为该终端设备分配了用于在上行共享信道上传输新数据的上行授 权， 且该上行授权能够容纳该功率剩余量报告时， 该终端设备依次判断 在每个服务小区上基站是否只调度了信道状态信息， 而没有分配上行授 权来传输上行共享信道的数据；
歩骤 302，若判断结果为是，则该终端设备获得存在该基站只调度了 信道状态信息， 而没有分配上行授权来传输上行共享信道的数据的服务 小区对应的最大配置输出功率 PCMAX;
歩骤 403， 将获得的该最大配置输出功率 PCMAX向该基站报告。
在上述实施例 1和 2中， 上述每个服务小区处于激活状态且配置了 上行载波。
在上述实施例 1和 2中， 在歩骤 202、 302中， 该终端设备从物理层 获得该最大配置输出功率 pCMAX。
在上述实施例 1和 2中， 在歩骤 203、 403中， 该终端设备将获得的 该最大配置输出功率 PCMAX包含在功率剩余量报告（HPR)中向基站上报。
在上述实施例 1和 2中， 在歩骤 201和 301中， 在当前子帧上终端 设备触发功率剩余量报告 PHR、 且基站为该终端设备分配了用于在上行 共享信道上传输新数据的上行授权， 且该上行授权能够容纳该功率剩余 量报告时， 根据目前协议规定， 该终端设备还可确定上报存在该上行授 权的服务小区对应的最大配置输出功率 PCMAX， 并且该终端设备可从物理 层获得该服务小区对应的最大配置输出功率 P™AX。 在本实施例中， 该终 端设备可将上述存在该上行授权的服务小区对应的最大配置输出功率
ΡθΜΛΧ ,以及存在该上行数据的非自适应重传的服务小区对应的最大配置输 出功率 P™ax或者存在该基站只调度了信道状态信息， 而没有分配上行授 权来传输上行共享信道的数据的服务小区对应的最大配置输出功率 PCMAX 均包含在功率剩余量报告 PHR中上报给基站。
图 4是本发明实施例 3的最大配置输出功率的报告方法的流程图。 以下结合图 1A、 IB和图 4对本发明实施例的最大配置输出功率的报告方 法进行说明。
如图 4所示， 在实际实施中， 在每个子帧， 该方法包括：
歩骤 401， 终端设备判断是否触发功率剩余量报告 PHR; 若判断结 果为是则执行歩骤 402， 否则结束过程；
其中， 如图 1A和 1B所示， 已触发 PHR。
歩骤 402， 若触发功率剩余量报告 PHR, 则该终端设备进一歩判断 基站是否为该终端设备分配了用于在上行共享信道上传输新数据的上行 授权 （UL gmnt); 若判断结果为是， 则执行歩骤 403， 否则结束；
其中， 如图 1A和 1B所示， 在服务小区 1上， 基站分配了用于上行 共享信道上传输新数据的上行授权 （见 103和 10 )。
歩骤 403，若基站为该终端设备分配了用于在上行共享信道上传输新 数据的上行授权， 则该终端设备进一歩判断该上行授权是否能够容纳该 功率剩余量报告 PHR,若判断结果为是，则执行歩骤 404，否则结束过程。
歩骤 404， 若判断结果为能够容纳该 PHR, 则按照目前协议规定， 该终 端设备可获得有该上行授权的服务小区对应的最大配置输出功率 Pc
其中， 如图 1A和 1B所示， 该终端设备获得服务小区 1的最大配置 输出功率 P™ax， 可从物理层获得， 获得过程与现有技术类似， 此处不再 赘述。
歩骤 405，该终端设备进一歩判断在每个服务小区上是否有上行数据 的非自适应重传； 或者终端设备判断在每个服务小区上基站是否只调度 了信道状态信息， 而没有分配上行授权来传输上行共享信道的数据； 判 断结果为是， 则执行歩骤 406， 否则执行歩骤 408 ;
其中， 如图 1A和 1B所示， 该终端设备可获知在服务小区 2上有上 述两种情况。
歩骤 406，若判断结果为是，则该终端设备获得存在该上行数据的非 自适应重传的服务小区对应的最大配置输出功率 Ρ™ΛΧ; 或者该终端设备 获得获得存在该基站只调度了信道状态信息， 而没有分配上行授权来传 输上行共享信道的数据的服务小区对应的最大配置输出功率 PCMAX;
其中， 同样， 终端设备可从物理层获得， 获得过程与现有技术类似， 此处不再赘述。
歩骤 407， 该终端设备将在歩骤 404和歩骤 406中获得的该最大配置 输出功率 PCMAX向该基站报告；
其中，可将上述最大配置输出功率 PCMAX包含在 PHR中一起上报基站， 这样，在图 1A和图 1B中，终端设备可在服务小区 1上发送上行数据和 PHR, 该 PHR可包括歩骤 401和歩骤 406中获得的服务小区 1和服务小区 2的最 大配置输出功率 PCMAX。
歩骤 408， 该终端设备将在歩骤 404获得的该最大配置输出功率 PCMAX 向该基站报告。
上面的流程只是例示性和说明性的， 根据本发明实施例的方法并非 必须包括上面每一个歩骤， 其中某些歩骤是可以删除、 合并或者变换次 序。 本发明实施例的方法不限于按照说明书中描述的时间顺序来执行， 也可以按照其他的时间顺序地、 并行地或独立地执行。 只要没有脱离本 发明的精神和范围， 这些变型例都应包括在本发明的范围内。 例如， 歩 骤 401可放在歩骤 402或 403只有之后判断，或者歩骤 401 -403合并执行， 歩骤 404可与歩骤 406合并执行等。
通过上述实施例， 如图 1A和图 1B两种场景下， 终端设备不仅可上 报服务小区 1的最大配置输出功率 Ρ™ΛΧ， 而且还能上报服务小区 2的最 大配置输出功率 PCMAX， 从而解决了现有技术中存在的问题。
由上述实施例可知， 通过本发明实施例的方法使得终端设备在一个 服务小区上即使没有有效的上行授权， 但有实际的物理传输， 如上行非 自适应重传或基站仅调度信道状态信息时， 也能够上报该服务小区对应 的最大配置输出功率的值， 从而不会影响该基站后续在该服务小区上对 该终端设备的发射功率的控制以及对其调制编码方式的确定和带宽调 度， 解决了现有技术中存在的问题。
本发明实施例还提供了一种终端设备，如下面的实施例 3和实施例 4 所述。 由于该终端设备解决问题的原理与上述基于该终端设备的报告方 法相似， 因此该终端设备的实施可以参见方法的实施， 重复之处不再赘述。
