目标参数包括的参数可以是用于PRACH重传的参数，即用于PRACH重复传输的参数与用于PRACH重传的参数相同，和/或，专用于PRACH重复传输的参数，在此不做限定。
终端基于目标参数确定PRACH重复传输中各PRACH传输的发送功率。

本实施例中，终端根据目标参数确定PRACH重复传输的发送功率，所述目标参数包括至少一个用于所述PRACH重复传输的参数；所述终端根据所述PRACH重复传输的发送功率进行PRACH重复传输。终端可以根据目标参数来确定PRACH重复传输中的PRACH传输的发送功率，提高传输性能。
在本申请一种实施例中，所述至少一个用于所述PRACH重复传输的参数包括如下至少一项：
(1)网络侧设备期望接收所述PRACH重复传输的第一目标功率电平。
第一目标功率电平可由网络侧设备配置，第一目标功率电平可为专用于所述PRACH重复传输的参数。

需要说明的是，消息3重复请求是用来请求msg3重复传输的一种PRACH，也就是说，这种PRACH下回复的随机接入响应(Random Access Response，RAR)可能会调度msg3的重复传输。
(3)网络侧设备期望接收PRACH传输的第二目标功率电平的偏移。
所述第二目标功率电平可为在所述终端不执行所述PRACH重复传输的情况下，所述网络侧设备期望接收PRACH传输的目标功率电平。

终端选择PRACH重复传输的PRACH资源时，可以优先选择专用于PRACH重复传输的参数，例如，第一目标功率电平和/或第一功率爬升步长；终端选择PRACH初传或PRACH重传的PRACH资源时，可以选择用于PRACH初传和重传的参数，例如，第二目标功率电平和/或第二功率爬升步长。
在本申请一种实施例中，所述终端使用所述第一目标功率电平的条件为：所述终端执行所述PRACH重复传输情况下用于所述PRACH重复传输的时频资源与所述终端不执行所述PRACH重复传输情况下用于PRACH传输的时频资源不共享。时频资源可理解为用于发送一个PRACH传输序列所需要的时频资源，例如PRACH机会(Occasion)，可简称RO，PRACH Occasion即是指用于发送一个PRACH传输序列所需要的时频资源。
也就是说，所述终端执行所述PRACH重复传输情况下用于所述PRACH重复传输的时频资源与所述终端不执行所述PRACH重复传输情况下用于PRACH传输(例如PRACH初传或PRACH重传)的时频资源不共享时，配置专用于所述PRACH重复传输的第一目标功率电平。

在本申请一种实施例中，第一目标PRACH传输的路径损耗根据在第一PRACH传输的第一个符号之前执行的路径损耗估计确定，所述第一目标PRACH传输包括所述PRACH重复传输中的至少两次PRACH传输，第一PRACH传输为所述第一目标PRACH传输中最先发送的PRACH。
第一PRACH传输可为所述PRACH重复传输中的第一次PRACH传输，也可为第N次PRACH传输，N大于或等于1，且小于或等于PRACH重复传输包括的传输次数，N为整数。如果所述PRACH重复传输中所有PRACH传输的路径损耗估计在第一次PRACH传输的第一个符号之前使用相同的参考信号估计，则所有PRACH传输计算获得的功率，可以预期有相同的路径损耗。如图3a所示，PRACH重复传输包括4次PRACH传输，分别为{Rep1，Rep2，Rep3，Rep4}，4次PRACH传输的路径损耗估计都基于同步信号块(Synchronization Signal and PBCH block，SSB)1，并在第一次PRACH传输之前进行估计，图3a中A所示的路径损耗估计时间为在第一次PRACH传输之前。
在本申请一种实施例中，第二目标PRACH传输的路径损耗根据在所述第二目标PRACH传输的第一个符号之前执行的路径损耗估计确定，所述第二目标PRACH传输为所述PRACH重复传输中的任意一次PRACH传输。
也就是说，在每一个PRACH传输的第一个符号之前估计该PRACH传输的路径损耗。如图3b所示，PRACH重复传输包括4次PRACH传输，分别为{Rep1，Rep2，Rep3，Rep4}，4次PRACH传输分别与SSB1，SSB2，SSB3，SSB4相关联。Rep i的路径损失是基于SSB i并在Rep i的第一个符号之前估计获得的，i＝1到4，即，图3b中B、C、D、E所示的路径损耗估计时间。
在本申请一种实施例中，所述PRACH重复传输的路径损耗根据如下至 少一项确定：
(1)所述PRACH重复传输中每一次PRACH传输的路径损耗基于对相同目标参考信号(例如SSB或信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS))的测量确定，也就是说，所述PRACH重复传输中每一次PRACH传输的路径损耗都采用相同的参考信号的进行测量。
所述目标参考信号包括如下其中一项：
与第二PRACH传输相关联的参考信号，其中，所述第二PRACH传输为第四目标PRACH传输中最先发送的PRACH传输，所述第四目标PRACH传输包括所述PRACH重复传输中的至少两次PRACH传输；第二PRACH传输可为所述PRACH重复传输中的第一次PRACH传输，也可为第N次PRACH传输；
所述参考信号集合中基于所述终端测量确定的参考信号接收功率(Reference Signal Receiving Power，RSRP)最高的参考信号；
所述参考信号集合中基于所述终端测量确定的RSRP最低的参考信号；
所述参考信号集合中基于所述终端测量确定的路径损耗最大的参考信号；
所述参考信号集合中基于所述终端测量确定的路径损耗最小的参考信号；
其中，所述参考信号集合包括与所述PRACH重复传输中每次PRACH传输相关联的参考信号。
(2)第三目标PRACH传输的路径损耗根据对与所述第三目标PRACH传输相关联的参考信号测量确定，所述第三目标PRACH传输为所述PRACH重复传输中的任意一次PRACH传输。也就是说，每个PRACH传输的路径损耗基于对与每个PRACH传输相关联的参考信号(例如，SSB或CSI-RS)的测量确定。
当所述PRACH重复传输中各PRACH传输关联相同的参考信号时，各PRACH传输采用相同的参考信号进行路径损耗估计；当所述PRACH重复传输中各PRACH传输关联不同的参考信号时，各PRACH传输采用不同的参考信号进行路径损耗估计。
本申请实施例中，使用专用于PRACH重复传输的参数配置，使得网络 侧设备可以配置相比于终端不执行PRACH重复传输时所用的优先级更高的功率配置，从而可以提高PRACH传输接收的可靠性。
本申请实施例提供了灵活的路径损耗(可以简称为路损)估计方式，例如，可以将PRACH重复传输中的某一个PRACH传输的路损估计用于所有PRACH传输，一方面，可以降低路损估计的复杂度，降低终端损耗。另一方面，在PRACH重复传输中各PRACH传输的发送功率相同的情况下，便于网络侧设备可以根据接收功率选出最好(例如接收功率最大)的PRACH传输，用于确定下行随机接入响应的发送。
另外，灵活的路损估计方式也可以是对PRACH重复传输中各PRACH传输分别进行路损估计，这样可以确保路损估计的精确性，从而确保各PRACH传输在网络侧设备接收到的接收功率是网络侧设备期望的。
