Abstract

本发明公开了一种功率余量上报方法及装置、计算机存储介质，所述方法包括：终端计算多个带宽部分BWP上的上行信号的功率余量PH，所述多个BWP为所述终端当前配置或激活的BWP；所述终端向网络设备发送所述多个BWP中的至少一个BWP上的上行信号的PH。

Description

一种功率余量上报方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种功率余量上报方法及装置、计算机存储介质。
背景技术
物理上行共享信道(PUSCH，Physical Uplink Shared Channel)功率余量(PH，Power Headroom)是指终端允许的最大传输功率与当前计算得到的PUSCH传输功率之间的差值，用公式可以简单的表示为：PH_PUSCH＝UEAllowedMaxTransPower–PuschPower，其中，PH_PUSCH表示PUSCH功率余量，UEAllowedMaxTransPower表示终端允许的最大传输功率，PuschPower表示当前计算得到的PUSCH传输功率。PUSCH功率余量表示的是除了当前PUSCH传输所使用的传输功率之外，终端还有多少传输功率可以使用，其中PuschPower并不是终端实际的发送功率，而是根据一定公式计算出的发送功率。PH_PUSCH的单位是dB，如果PH_PUSCH是负值则表示终端计算出的发送功率超过了其最大允许的发送功率。
在新无线(NR，New Radio)中，终端需要针对PUSCH和探测参考信号(SRS，Sounding Reference Signal)分别进行功率余量上报(Power Headroom Report，PHR)。终端不仅需要针对当前传输了PUSCH或SRS的载波进行PH上报，同时也要针对未传输PUSCH或SRS的载波进行PH上报，从而为网络侧在该载波上的调度提供参考。
此外，在NR中，一个载波可以包含最多四个带宽部分(BWP，Bandwidth Part)，网络侧可以动态的激活其中的部分BWP用于数据或者参考信号传输。不同的BWP可以分配不同的带宽，并用于不同业务类型的数据传输。例如，一个BWP可以用于增强型移动宽带(eMBB，Enhance Mobile Broadband)的数据传输，另一个BWP可以用于低时延高可靠通信(URLLC，Ultra Reliable Low Latency Communication)的数据传输。目前，每个载波只有一个PHR，网络侧无法获得载波内每个BWP上具体的功率余量信息，从而无法合理调度各BWP上的上行信号传输。而且，由于PUSCH传输可以在多个BWP之间动态切换，网络侧需要同时有多个BWP上的实时功率余量信息，才能进 行合理的BWP切换。

上述公式中的参数是为该BWP k上的PUSCH而配置或指示的功率控制参数(即每个BWP专属的参数)，其中，

为终端在该BWP上假设的最大发送功率，P O_PUSCH,f,c,k(j)为PUSCH目标接收功率，α f,c,k(j)为路损因子，PL f,c,k(q d)为路损估计值，f f,c,k(i,l)为闭环功率调整因子。。
示例三：终端基于载波c上的BWP k上的SRS的传输参数和功率控制参数计算该BWP上的SRS的真实PH的方法如下：
PH type3,f,c,k(i,q s,l)＝
P CMAX,f,c,k(i)-{P O_SRS,f,c,k(q s)+10log 10(2 μ·M SRS,f,c,k(i))+α SRS,f,c,k(q s)·PL f,c,k(q s)+h f,c,k(i,l)}

步骤102：所述终端向网络设备发送所述多个BWP中的至少一个BWP上的上行信号的PH。
在一实施方式中，所述终端向网络设备发送所述多个BWP中的第一BWP上的上行信号的第一PH，以及所述多个BWP中除所述第一BWP以外的至少一个BWP上的上行信号的PH与所述第一PH的差值。具体地，终端只上报一个BWP上的上行信号的实际PH值，其他BWP上的上行信号只上报差分的PH值，从而可以节约上报的信令开销。这里上报实际PH值的BWP可以是所述多个BWP中索引最低的BWP，或者所述多个BWP中优先级最高的BWP。
在一实施方式中，所述终端将所述多个BWP中的至少一个BWP中每个BWP的BWP索引与所述BWP对应的PH一起发送给所述网络设备。从而网络侧可以根据该索引确定每个PH对应的BWP。
在一实施方式中，所述终端向网络设备发送所述多个BWP中的处于激活状态的BWP上的上行信号的PH。具体地，终端在某个时刻上报PH时，该时刻所述多个BWP中只有一个或者几个BWP是激活的，则终端只上报这些激活的BWP对应的PH，不上报非激活的BWP对应的PH。如果每个时刻只有一个BWP是激活的，则网络侧根据当前激活的BWP，就可以知道上报的PH对应的BWP。
在一实施方式中，所述终端向所述网络设备发送所述多个BWP中对应的PH取值最大或者最小的至少一个BWP上的上行信号的PH。
在一实施方式中，所述多个BWP属于第一载波；所述方法还包括：
所述终端基于所述第一载波上的所述多个BWP中的至少一个BWP上的上行信号的PH，计算所述第一载波上的上行信号的PH(计算的方法可以是取平均值，求和等)；
所述终端向所述网络设备发送所述第一载波上的上行信号的PH。
这里，所述终端基于所述第一载波上的所述多个BWP中的至少一个BWP上的上 行信号的PH，计算所述第一载波上的上行信号的PH，通过以下两种方式中的其中一种实现：
方式一：所述终端基于所述第一载波上的所述多个BWP中的全部BWP上的上行信号的PH，计算所述第一载波上的上行信号的PH。
例如：网络侧为终端的一个载波上配置了4个BWP，终端分别计算每个BWP上的PUSCH或SRS的PH，并将所述4个BWP的PH的线性值进行平均后，得到所述载波的PH，并上报给网络侧。
方式二：所述终端基于所述第一载波上的所述多个BWP中的处于激活状态的BWP上的上行信号的PH，计算所述第一载波上的上行信号的PH。
例如：网络侧为终端的一个载波上配置了4个BWP，但是在PH上报的时刻只激活了其中2个BWP，则终端将激活的2个BWP的PH的线性值进行平均后，得到所述载波的PH，并上报给网络侧。
本发明实施例的技术方案，终端可以上报一个载波上配置的多个BWP各自对应的PH，从而网络侧可以灵活在多个BWP之间进行切换，同时确定各个BWP上的资源分配和上行功率控制参数。
