Description

功率控制的路损计算方法及装置 技术领域
本公开涉及通信领域，尤其涉及功率控制的路损计算方法及装置。
背景技术
目前，为了避免用户设备在进行直连通信时对该用户设备的上行通信的干扰，用户设备的直连通信的发送功率值可以按照下行路损的大小进行控制。例如，当用户设备移动到距离基站较远的位置时，该用户设备可以使用较高的发送功率值进行直连通信，而当该用户设备移动到离基站较近的位置时，可以使用较低的发送功率值进行直连通信。可以看出，直连通信的用户设备的发送功率值可以是个可变的值。
由于用户设备测量参考信号功率值需要通过高层来进行测量，需要较长时间段内多个测量结果的加权平均值，与上行通信过程中进行功率控制的过程不同的是，在上行通信中，基站的发送功率值是不变的，而直连通信中，如果作为发送端的用户设备所采用的发送功率值可变，很难根据作为接收端的用户设备返回的经过高层滤波得到的参考信号功率值，得到正确的路损估计，会影响直连通信的功率控制的效果。

本公开实施例提供了一种功率控制的路损计算方法，可以用于直连单播通信的发送端设备，参照1所示，图1是根据一实施例示出的一种功率控制的路损计算方法流程图，该方法可以包括以下步骤：
在步骤101中，根据与接收端设备进行直连单播通信时所采用的至少一个发送功率值，确定一个目标发送功率值。
本步骤中，发送端设备可以在与接收端设备进行直连单播通信时，根据自身采用的至少一个发送功率值，确定出一个等效的目标发送功率值。
在步骤102中，接收所述接收端设备返回的当前一次的目标参考信号接收功率RSRP值。
其中，目标RSRP是接收端设备经过高层滤波，例如层3滤波得到的RSRP值。目标RSRP值F n可以采用以下公式进行计算：
F n＝(1-a)×F n-1+a×M n   公式1
其中，F n为接收端设备当前一次采用层3滤波得到的RSRP值，即目标RSRP值，F n-1是接收端设备上一次采用层3滤波得到的RSRP值，M n是最近一次接收端设备物理层的测量结果，a＝1/2 (ki/4)，k i为配置的预设值。
接收端设备可以采用上述公式1计算得到目标RSRP值，并通过直连链路返回给所述发送端设备。
在步骤103中，根据所述目标发送功率值和当前一次的所述目标RSRP值，确定目标路损值。
在本公开实施例中，发送端设备可以根据确定的等效目标发送功率值和当前一次接收到的接收端设备返回的目标RSRP值，确定得到目标路损值。
上述实施例中，在确定功率控制的路损时，可以由发送端设备根据与接收端设备进行直连单播通信时所采用的至少一个发送功率值，确定一个目标发送功率值，在根据该目标发送功率值和接收到的接收端设备返回的当前依次的目标RSRP值，确定目标路损值，提高了目标路损值的准确性，从而提高了直连通信的功率控制效果，可以为直连通信提供更可靠的通信质量，可用性更高。
在一实施例中，至少一个发送功率值是指发送端设备在指定时间段内的至少一个发送功率值。
其中，由于接收端设备进行高层滤波得到的目标RSRP值是经过一段时间才能得到的测量结果，因此，为了后续提高目标路损值的准确性，可以将指定时间段确定为从上一次接收到所述接收端设备返回的所述目标RSRP值的时间点开始、到接收到所述接收端设备返回的当前一次的所述目标RSRP值的时间点为止的时间段。也就是说，发送端设备相邻两次接收到目标RSRP值的时间段作为指定时间段，在这一指定时间段内可以根据发送端设备发送的至少一个发送功率值，确定出等效的目标发送功率值。
上述实施例中，发送端确定的至少一个发送功率值是在指定时间段内的至少一个发送功率值，采用指定时间段内的至少一个发送功率值，确定一个目标发送功率值，使得目标发送功率值更加准确。
在一实施例中，步骤101可以包括：
在步骤101-1中，将接收到所述接收端设备返回的当前一次的所述目标RSRP之前，最后一次采用的所述发送功率值作为所述目标发送功率值。
本公开实施例中，可以在发送端设备与接收端设备进行直连单播通信时所采用的至少一个发送功率值中，将接收到接收端设备返回的当前一次的目标RSRP值之前，最后一次采用的发送功率值作为目标发送功率值。
例如，发送端设备在接收到接收端设备返回的当前一次目标RSRP之前，按照时间顺序分别采用了P 1、P 2、P 3和P 4四个发送功率值，可以直接将P 4作为目标发送功率值。
在一实施例中，步骤101可以包括：
在步骤101-2中，计算至少一个所述发送功率值的算数平均值，将所述算数平均值作为所述目标发送功率值。
发送端设备将指定时间段内自身的至少一个所述发送功率值的算数平均值，作为目标发送功率值。
例如，指定时间段内，发送端设备分别采用了P 1、P 2、P 3和P 4四个发送功率值，则目标发送功率值P＝(P 1+P 2+P 3+P 4)/4。
在一实施例中，参照2所示，图2是根据图1所示的实施例示出的另 一种功率控制的路损计算方法流程图，步骤101可以包括
在步骤101-3中，按照由前到后的时间顺序，基于预设的滤波参数值，对所采用的至少一个所述发送功率值进行滤波后，分别得到前N个所述发送功率值对应的加权平均值。
在本步骤中，发送端设备可以对采用的至少一个发送功率值按照时间由前到后的顺序，通过预设的滤波参数值，分别对每个发送功率值进行滤波，得到前N个发送功率值对应的加权平均值。
在步骤101-4中，截止接收到所述接收端设备返回的当前一次的所述目标RSRP值的时间点，将所有所述发送功率值对应的所述加权平均值作为所述目标发送功率值。
在本步骤中，截止接收到所述接收端设备返回的当前一次的所述目标RSRP值的时间点，发送端设备可以将在指定时间段内所有发送功率值对应的所述加权平均值作为所述目标发送功率值。
在一实施例中，步骤101-3中前N个所述发送功率值对应的加权平均值Q n可以通过以下公式计算：
Q n＝(1–a’)×Q n-1+a’×P n     公式2
其中，Q n-1是前N-1个发送功率值对应的加权平均值，a’是滤波参数值，P n是第N个发送功率值。
例如，按照由前到后的时间顺序，发送端设备在指定时间段内共采用了P 1、P 2、P 3和P 4四个发送功率值，假设a’为1/2，分别对应的加权平均值如下：
Q 1＝(1–a’)×Q 0+a’×P 1＝(1/2)P 1，
Q 2＝(1–a’)×Q 1+a’×P 2＝(1/2)×(1/2)×P 1+(1/2)×P 2＝(1/4)P 1+(1/2)P 2，
Q 3＝(1–a’)×Q 2+a’×P 3＝(1/8)P 1+(1/4)P 2+(1/2)P 3，
Q 4＝(1–a’)×Q 3+a’×P 4＝(1/16)P 1+(1/8)P 2+(1/4)P 3+(1/2)P 4。
在本公开实施例中，可以将所有发送功率值P 1、P 2、P 3和P 4对应的加 权平均值Q 4作为目标功率值P。
上述实施例中，可以将接收到接收端设备返回的当前一次的目标RSRP值之前，最后一次采用的发送功率值作为目标发送功率值，或者直接将至少一个发送功率值的算数平均值作为目标发送功率值。或者还可以按照由前到后的时间顺序，基于预设的滤波参数值，对所采用的至少一个所述发送功率值进行滤波后，分别得到前N个所述发送功率值对应的加权平均值，截止接收到所述接收端设备返回的当前一次的所述目标RSRP值的时间点，将所有所述发送功率值对应的所述加权平均值作为所述目标发送功率值。通过上述方式，可以确定出一个目标发送功率值，提高了目标路损值的准确性，从而提高了直连通信的功率控制效果，可以为直连通信提供更可靠的通信质量，可用性更高。
在一实施例中，针对步骤102，可以采用以下公式计算目标路损值PL：
PL＝Eff_referenceSignalPower–higher layer filtered RSRP   公式3
其中，Eff_referenceSignalPower是目标发送功率值，higher layer filtered RSRP是当前一次接收到的目标RPRP值。
上述实施例中，可以计算所述目标发送功率值和当前一次的所述目标RSRP值的差值，从而得到所述目标路损值，提高了目标路损值的准确性，从而提高了直连通信的功率控制效果，可以为直连通信提供更可靠的通信质量，可用性更高。
