3rd, the distinctive parameters of UE that upstream service AP is determined are, it is necessary to which explanation, the upstream service AP adjust according to itself
Degree, resource etc. determine the parameter；The UE is peculiar to refer to that parameter can be different for each UE, and this is mainly by eNodeB
Or AP determines according to AP own schedules, resource etc..Such as：Characterized in LTE system and it is expected interference of the UE to other cells
Control parameter (PO_UE_PUSCH (j)) etc.；
Then, eNodeB calculates the uplink transmission power adjustment amount of the UE according to these parameters of acquisition, then under
Row signaling passes to the UE, after the UE receives the downlink signaling, is mapped according to corresponding mode, it is up to obtain this
After transmit power adjustment amount, ascending power is adjusted.
Can be to from all and eNodeB calculates the uplink transmission power adjustment amount according to the parameter of acquisition
The relevant parameter that row service AP is obtained takes one of them；Maximum is taken in the relevant parameter either obtained from all upstream service AP
Value takes minimum value or averaged.
Wherein, said process can be carried out in the up and/or downstream service AP changes of the UE.ENodeB obtains institute
State the mode of the upstream service AP parameter, can be by the various connected modes between the eNodeB and the AP,

ENodeB is connected to AP1 and AP2, and the service AP of UE uplink and downlink is identical, and where figure 1 shows only
There is AP1 services UE situation, now prior art can just reach preferable performance；And Fig. 2 shows that AP1 and AP2 take jointly
Business UE situation, if using prior art, i.e. .UE only receives downlink signaling, the mark seen in Fig. 1 " downlink signaling " from AP1
(including AP1 power control information PO_NORMINAL_PUSCH (j) and PO_UE_PUSCH (j) information) simultaneously only detects
AP1 to UE path loss, so as to which UE uplink transmission power be calculated, then the upward signal that UE is sent can be caused with AP1
Desired power reaches AP1, and the power control information of the power control information and AP2 due to AP1 has differences, and described
UE to AP1 and AP2 path loss then causes the UE to send the up transmission of upward signal to the AP2 there is also difference
Power is too big or too small.Therefore, prior art can not normal work in such scene.Then may be used using technical solution of the present invention
To realize well, can specifically follow the steps below：
1st, AP1 and AP2 detects the up path loss between UE respectively；
2nd, the path loss and the parameter related to uplink power control are passed to eNodeB by AP1 and AP2 respectively, wherein
