Description

功率余量报告的上报方法和装置 技术领域
本申请涉及通信技术，尤其涉及一种功率余量报告的上报方法和装置。
背景技术
为了帮助调度器选择不导致用户设备(User Equipment，UE)功率受限的调制和编码机制(Modulation and Coding Scheme，MCS)和资源大小M，UE可以被配置为定期提供关于自己的功率使用情况的功率余量报告(Power Headroom Report，PHR)，即UE向网络侧报告功率余量(Power Headroom，PH)的过程。
LTE release 10定义了两个不同类型的功率余量报告，Type 1和Type 2。其中Type1上报的PH为假设服务小区上只有PUSCH传输的PH，而Type-2上报的PH为假设服务小区上有组合的PUSCH和PUCCH传输的PH。
Type 1功率余量(PH)对一个特定子帧有效，假设UE在该子帧中具有真实调度的PUSCH传输的计算表达式如下：
PH＝PCMAX,c-(P0,PUSCH+αPLDL+10·log10(M)+ΔMCS+δ)
其中，PCMAX,c为UE在服务小区的最大发送功率，M为PHR对应的子帧中使用的资源大小，ΔMCS为PHR对应的子帧中使用的调制和编码机制。
由上述PH的计算公式可知，PH是PCMAX,c与(P0,PUSCH+αPLDL+10·log10(M)+ΔMCS+δ)之间的差，而(P0,PUSCH+αPLDL+10·log10(M)+ΔMCS+δ)并没有上限，因此通过上式计算的PH可能为负值。与Type 1类似，Type 2功率余量上报被定义为每服务小区的最大发送功率减去PUSCH与PUCCH发送功率之和的差，而PUSCH和PUCCH发送功率之和同样是一个没有上限的值，因此PH也可能为负值。如果PH为负值，则表示网络侧调度了超过UE的可用发送功率能够支持的更高数据速率。
然而，随着通信技术的不断发展，高频段和超密集组网得到了广泛应用，对于超密集组网，一个第五代基站(gNB)可以对应一个或多个发送和接收点(Transmission and Reception Point，TRP)，因此每个新无线接口(New Radio，NR)小区也可以对应一个或多个TRP，当一个小区对应多个TRP时，这些TRP组成TRP group，即TRPG，一个小区可以包括一个TRPG。对于高频段组网，通过在不同方向上被成形的波束(beam)可以覆盖业务区域，每个TRP的区域可以由多个窄的高增益beam覆盖。但是上述PH机制的计算和报告是针对每个服务小区(即成员载波)，包括主载波PCell或者可选的辅载波SCell，上述HR机制的计算和报告不能满足对于高频段和超密集组网的场景中的PHR需求，会引起UE受限而导致上行数据发送失败的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本文所涉及的用户设备(User Equipment，UE)可以表示任意适用的端用户设备，可以包括(或可以表示)诸如无线发送/接收单元(wireless transmit/receive unit，WTRU)、移动站、移动节点、移动设备、固定或移动签约单元、寻呼机、移动电话、掌上电脑(personal digital assistant，PDA)、智能手机、笔记本型电脑、计算机、触摸屏设备、无线传感器或消费电子设备等设备。此处的“移动”站/节点/设备表示与无线(或移动)网络连接的站/节点/设备，而并不一定与该站/节点/设备的实际移动性有关。
本文所涉及的“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
图1为本发明实施例的一种应用场景示意图，如图1所示，一个新无线接口(New Radio，简称NR)小区中可以包括一个或者多个TRP，其中，多个TRP可以对应一个TRPG，小区可以包括一个TRPG，UE可以利用多个TRP发送上行数据。TRP采用的频段可以是低频也可以是高频，当TRP采用高频的方式部署时，可以使用波束成形(beamforming)技术来抵抗高频链路的脆弱性。每个TRP的区域可以由多个窄的高增益波束(beam)覆盖，每个TRP可以通过一个或者多个波束(beam)与UE进行通信。以图1所示的应用场景进行举例说明，三个NR小区分别为NR cell1、NR cell2和NR cell3，其中，gNB1包括NR Cell 1&2调度器(scheduler)，该NR Cell 1&2scheduler与NR cell1中的TRP和NR cell2中的TRP建立通信连接，NR cell1包括 TRP1-1、TRP1-2和TRP1-3，NR cell2包括TRP2。gNB2包括NR Cell 3调度器(scheduler)，该NR Cell 3scheduler与NR cell3中的TRP建立通信连接，NR cell3包括TRP3-1和TRP3-2。
为了满足高频段和/或超密集组网的场景中的PHR需求，本发明实施例提供一种功率余量报告的上报方法，通过基站对UE的PHR的级别进行配置，UE根据配置进行PH计算及上报，从而实现基站根据调度需求获取UE在相应级别的PH，进而根据PHR对UE进行合理调度。下面采用几个具体的实施例对本发明实施例的功率余量报告的上报方法进行具体解释说明。
需要说明的是，本文涉及的基站和调度器可以相互替换，以执行本发明实施例的下述方法实施例。基站即指如图1所示的gNB1或者gNB2。调度器即指如图1所示的NR Cell 1&2调度器(scheduler)、或者NR Cell 3调度器(scheduler)。

步骤102、用户设备根据所述PHR的级别信息确定所述PHR的级别信息对应的PHR。
具体的，当步骤101中的PHR的级别信息包括TRPG级别信息、TRP级别信息、波束级别信息和基站级别信息中任意一项时，用户设备可以根据PHR的级别信息确定与该PHR的级别信息对应的PH，并根据该PH生成该PHR的级别信息对应的PHR。当步骤101中的PHR的级别信息包括TRPG级别信息、TRP级别信息、波束级别信息和基站级别信息中任意多项时，用户设备可以根据多个PHR的级别信息分别确定与每个PHR的级别信息对应的PH，并根据每个PHR的级别信息对应的PH生成每个PHR的级别信息对应的PHR，即用户设备可以根据PHR的级别信息确定各个级别信息对应的PHR。将多个PHR的级别信息对应的PHR和小区级别的PHR进行组合上报。当然可以理解的，也可以分别进行上报。
步骤103、用户设备向基站发送所述PHR的级别信息对应的PHR。
基站接收用户设备发送的所述PHR的级别信息对应的PHR。
可选的，步骤101的一种具体的可实施方式为：基站向用户设备发送无线资源控制(Radio Resource Control，RRC)信令，该无线资源控制信令可以包括该PHR的级别信息。
可选的，步骤101的另一种具体的可实施方式为：基站向用户设备发送介质访问控制控制(Media Access Control，MAC)控制信元，该MAC控制信元可以包括该PHR 的级别信息。

下面采用几个具体的实施例，对图2所示方法实施例的技术方案进行详细说明。
图3为本发明实施例的另一种功率余量报告的上报方法的流程图，本实施例对PHR的级别信息包括TRPG级别信息的功率余量报告的上报方法进行具体解释说明，如图3所示，本实施例的方法可以包括：
步骤201、基站向用户设备发送功率余量报告PHR的级别信息。
用户设备接收基站发送的PHR的级别信息。
其中，步骤201的具体解释说明可以参见步骤101。其中，当PHR的级别信息包括TRPG级别信息时，可以执行下述步骤202至步骤205。
步骤202、用户设备根据所述TRPG级别信息确定所述用户设备对于至少一个TRPG允许的最大发送功率。
具体的，当该PHR的级别信息包括TRPG级别信息，用户设备确定该用户设备对于一个或者多个TRPG允许的最大发送功率，以图1所示应用场景做进一步举例说明，如图1所示的用户设备可以通过TRP1-1、TRP1-2、TRP2以及TRP3-1发送上行数据，其中，TRP1-1和TRP1-2属于TRPG1，TRP2属于TRPG2，TRP3-1属于TRPG3，则用户设备根据该TRPG级别信息确定用户设备对于TRPG1允许的最大发送功率Pcmax,TRPG1、用户设备对于TRPG2允许的最大发送功率Pcmax,TRPG2以及用户设备对于TRPG3允许的最大发送功率Pcmax,TRPG3。
其中，用户设备还可以根据所述TRPG级别信息确定用户设备到各个TRPG的上行发送功率。具体的，以图1所示应用场景做进一步举例说明，用户设备确定用户设备到TRPG1的上行发送功率、用户设备到TRPG2的上行发送功率以及用户设备到TRPG3的上行发送功率。
步骤203、用户设备根据所述至少一个TRPG允许的最大发送功率和所述用户设备到各个TRPG的上行发送功率分别确定每个TRPG对应的PH。
其中，所述用户设备到每个TRPG的上行发送功率为所述用户设备在每个TRPG中包括的所有TRP的上行发送功率总和，所述用户设备在每个TRP的上行发送功率为所述用户设备对每个TRP在所有beam上的上行发送功率的总和。
其中，步骤203的一种具体的可实施方式为用户设备确定每个TRPG对应的PH采用如下式的方式：
PHTRPGi＝Pcmax,TRPGi-UE到TRPGi的上行发送功率
其中，上述公式中i取正整数，例如Pcmax,TRPGi可以为Pcmax,TRPG1、Pcmax,TRPG2、Pcmax,TRPG3等。上式中的UE到TRPGi的上行发送功率具体指UE在报告PHR的子帧中对TRPGi内的所有TRP在所有beam上的发送功率的总和。以图1所示的TRPG1为例进行举例说明，UE到TRPG1的上行发送功率为UE在beam1、beam2和beam3上的发送功率的总和，那么，PHTRPG1等于UE在该子帧中的Pcmax,TRPG1减去UE在beam1、beam2和beam3 上的发送功率的总和。
步骤204、用户设备根据所述每个TRPG对应的PH生成所述TRPG级别信息对应的PHR。
其中，所述TRPG级别信息对应的PHR包括所述至少一个TRPG的索引和与每个TRPG的索引对应的PH。可选的，该TRPG级别信息对应的PHR还可以包括Pcmax,TRPGi等参数信息。
步骤205、用户设备向基站发送所述TRPG级别信息对应的PHR。
具体的，用户设备可以采用周期上报的方式向基站发送PHR，也采用条件触发上报的方式向基站发送PHR，还可以是基站给予指示的方式向基站发送PHR。本发明实施例对此不做限制。

图4A为本发明实施例的另一种功率余量报告的上报方法的流程图，图4B为本发明实施例的一种TRP级别信息对应的PHR采用的MAC CE的格式示意图，图4C为本发明实施例的另一种TRP级别信息对应的PHR采用的MAC CE的格式示意图，图4D为本发明实施例的又一种TRP级别信息对应的PHR采用的MAC CE的格式示意图，本实施例对PHR的级别信息包括TRP级别信息的功率余量报告的上报方法进行具体解释说明，如图4A所示，本实施例的方法可以包括：
步骤301、基站向用户设备发送功率余量报告PHR的级别信息。
用户设备接收基站发送的PHR的级别信息。
其中，步骤301的具体解释说明可以参见步骤101。其中，当PHR的级别信息包括TRP级别信息时，可以执行下述步骤302至步骤305。
步骤302、用户设备根据所述TRP级别信息确定所述用户设备对于至少一个TRP允许的最大发送功率。
具体的，当该PHR的级别信息包括TRP级别信息，用户设备确定该用户设备对于一个或者多个TRP允许的最大发送功率，以图1所示应用场景做进一步举例说明，如图1所示的用户设备可以通过TRP1-1、TRP1-2、TRP2以及TRP3-1发送上行数据，则用户设备根据该TRP级别信息确定用户设备对于TRP1-1允许的最大发送功率Pcmax,TRP1-1、用户设备对于TRP1-2允许的最大发送功率Pcmax,TRP1-2、用户设备对于TRP2允许的最大发送功率Pcmax,TRP2以及用户设备对于TRP3-1允许的最大发送功率Pcmax,TRP3-1。
其中，用户设备还可以根据所述TRP级别信息确定用户设备到各个TRP的上行发送功率。具体的，以图1所示应用场景做进一步举例说明，用户设备确定用户设备到TRP1-1的上行发送功率、用户设备到TRP1-2的上行发送功率、用户设备到TRP2的上行发送功率以及用户设备到TRP3-1的上行发送功率。
步骤303、用户设备根据所述至少一个TRP允许的最大发送功率和所述用户设备 到各个TRP的上行发送功率分别确定每个TRP对应的PH。
其中，所述用户设备到每个TRP的上行发送功率为所述用户设备在每个TRP中包括的所有beam的上行发送功率总和。
其中，步骤303的一种具体的可实施方式为用户设备确定每个TRP对应的PH采用如下式的方式：
PHTRPi-j＝Pcmax,TRPi-j-UE到TRPi-j的上行发送功率
其中，上述公式中i取正整数，j取正整数，其中，i具体可以指代TRPG的编号，j具体可以指在TRPG中TRP的编号，例如Pcmax,TRPi-j可以为Pcmax,TRP1-1、Pcmax,TRP1-2、Pcmax,TRP3-1等，其中，Pcmax,TRP1-1即指UE对于TRP1-1允许的最大发送功率。需要说明的是，当TRPG中只有一个TRP时，可以没有j的编号。当然可以理解的，i-j也可以表示为n，即用一个编号唯一表示一个TRP，本发明实施例仅以i-j做示意性举例说明。上式中的UE到TRPi-j的上行发送功率具体指UE在报告PHR的子帧中在对TRPi-j的所有beam上的发送功率的总和。以图1所示的TRP1-2为例进行举例说明，UE到TRP1-2的上行发送功率为UE在beam2和beam3上的发送功率的总和，那么，PHTRP1-2等于UE在该子帧中的Pcmax,TRP1-2减去UE在beam2和beam3上的发送功率的总和。
步骤304、用户设备根据所述每个TRP对应的PH生成所述TRP级别信息对应的PHR。
其中，所述TRP级别信息对应的PHR包括所述至少一个TRP对应的PH。可选的，该TRP级别信息对应的PHR还可以包括每个TRP的索引。可选的，该TRP级别信息对应的PHR还可以包括Pcmax,TRPi-j等参数信息。
一种可实现的方式，TRP级别信息对应的PHR具体可以采用如图4B所示的MAC CE。如图4B所示，其中，第一行用于携带TRP的索引，第二行至第2n+1行用于携带与TRP的索引对应的PH、Pcmax,TRPi-j，其中，该MAC CE的大小可变，具体与TRP的索引对应的PH有关，其中，Pcmax,TRPi-j可携带也可以不携带。如图4B所示，第二行携带PHTRP1-1，第三行携带Pcmax,TRP1-1。举例而言，如图4B所示的T1可以携带TRP1-1的索引，T2可以携带TRP1-2的索引。

步骤402、用户设备根据所述波束级别信息确定所述用户设备对于至少一个波束允许的最大发送功率。
具体的，当该PHR的级别信息包括波束级别信息，用户设备确定该用户设备对于一个或者多个波束允许的最大发送功率，以图1所示应用场景做进一步举例说明，如图1所示的用户设备可以通过beam1、beam2、beam3、beam4和beam5发送上行数据，则用户设备根据该波束级别信息确定用户设备对于beam1允许的最大发送功率Pcmax,beam1、用户设备对于beam2允许的最大发送功率Pcmax,beam2、用户设备对于beam3允许的最大发送功率Pcmax,beam3、用户设备对于beam4允许的最大发送功率Pcmax,beam4以及用户设备对于beam5允许的最大发送功率Pcmax,beam5。

步骤403、用户设备根据所述至少一个波束允许的最大发送功率和所述用户设备在各个波束的上行发送功率分别确定每个波束对应的PH。
其中，步骤403的一种具体的可实施方式为用户设备确定每个波束对应的PH采用如下式的方式：
PHbeam n＝Pcmax,beam n-UE在beam n的上行发送功率
其中，上述公式中n取正整数，例如Pcmax,beam n可以为Pcmax,beam1、Pcmax,beam2、Pcmax,beam3 等，其中，Pcmax,beam1即指UE在beam1允许的最大发送功率。上式中的UE在beam n的上行发送功率具体指UE在报告PHR的子帧中在beam1上的发送功率。以图1所示的beam1为例进行举例说明，PHbeam1等于UE Pcmax,beam1减去UE在beam1上的发送功率。

又一种可能的实现方式，也采用如图5D所示MAC CE发送PHR，与上述再一种可能的实现方式不同，一个MAC CE携带一个beam的PHR，且该beam的PHR通过该beam发送到对应的TRP或者调度器上，接收到PHR的TRP将该PHR报告给调度器，由调度器根据beam索引(或标识等)统一处理。以图1所示应用场景做进一步举例说明，UE对beam2的PHR可以在beam2中发送给TRP1-2，UE对beam3的PHR可以在beam3中发送给TRP1-2。TRP1-2根据收到PHR所在的beam获取beam索引，再将beam索引和beam的PHR发送给调度器。调度器根据beam索引等统一处理。

其中，上述公式中m取任意正整数，例如Pcmax,gNB m可以为Pcmax,gNB1、Pcmax,gNB2等，其中，Pcmax,gNB1即指UE到个gNB1允许的最大发送功率。上式中的UE在gNB m的上行发送功率具体指UE在报告PHR的子帧中向gNB1内所有小区的TRP的所有beam的发送功率总和。以图1所示的gNB1为例进行举例说明，PHgNB1等 于UE Pcmax,gNB1减去UE在beam1、beam2、beam3和beam4的发送功率总和。
步骤504、用户设备根据每个基站对应的PH生成所述基站级别信息对应的PHR。
其中，所述基站级别信息对应的PHR包括所述至少一个基站的索引和与每个基站的索引对应的PH。可选的，该基站级别信息对应的PHR还可以包括Pcmax,gNB m等参数信息。
一种可实现的方式，基站级别信息对应的PHR具体可以采用如图6B所示的MAC CE。如图6B所示，其中，第一行用于携带gNB1的索引，第二行至第2n+1行用于携带与gNB1的索引对应的PH、Pcmax,gNB m，其中，该MAC CE的大小可变，具体与基站的索引对应的PH有关，其中，Pcmax,gNB m可携带也可以不携带。如图6B所示，第二行携带PHgNB1，第三行携带Pcmax,gNB1。举例而言，如图6B所示的N1可以携带gNB1的索引。

由此可见，本发明实施例的基站可以根据需求灵活向用户设备发送PHR的级别信息，使得用户设备根据该PHR的级别信息上报PHR，从而使得上报PHR的方式更为灵活、有效。
需要说明的是，UE在发送PHR的子帧中在beam和/或TRP上没有进行任何发送，或者UE在发送PHR的子帧中在beam和/或TRP上没有发送PUCCH和/或PUSCH，则基站也可以采用上述方法实施例的实施方式向UE请求PHR。在UE执行多连接操作时，基站也可以指示UE上报该UE对其他服务基站的任意级别的PHR。
另外，本发明实施例的PHR的上报方法也可以应用与无线局域网等通信技术中。
