Example Embodiment
[0096] Example one
[0097] This embodiment is based on figure 2 The scenario shown is an application environment of the method for the mobile terminal to transmit uplink signals, where the mobile terminal is a UE and the serving base station is the micro base station 2.
[0098] There are multiple uplink power control formulas for each type of uplink signal in the UE. The eNB determines the indication according to the uplink signal reception mode, so that the UE selects the corresponding uplink power control formula to determine the uplink signal transmission power according to the indication determined by the eNB.
[0099] For example, for the uplink PUCCH, two uplink power control formulas can be set in the UE:
[0100] P T1 =min{P max , P 0,1 +PL DL, 1 +Δ Format, 1 +δ 1 } (41)
[0101] P T2 =min{P max , P 0,2 +PL DL, 2 +Δ Format, 2 +δ 2 } (42)
[0102] Among them, the uplink power control formula (41) is for the UE to determine the uplink PDCCH transmit power P when the micro ...
Example Embodiment
[0115] Example two
[0116] Similar to the first embodiment, in the UE, multiple uplink power control formulas are set for each type of uplink signal, but each uplink power control formula only performs independent closed-loop control, and the other variables of each uplink power control formula do The same configuration.
[0117] For example, for the uplink PUCCH, the following uplink power control formula is used to determine the transmit power of the uplink PUCCH:
[0118] P T1 =min{P max , P 0 +PL DL +Δ Format +δ 1 } (71)
[0119] P T2 =min{P max , P 0 +PL DL +Δ Format +δ 2 } (72)
[0120] From the above uplink power control formula (71) and uplink power control formula (72), it can be seen that for P in different uplink power control formulas 0 ,Δ Format Make the same configuration and let the UE use the same path loss to estimate PL DL , But each process is independently closed-loop power control, that is, δ 1 And δ 2 Perform independent adjustments, and adjust δ in each ...
Example Embodiment
[0129] Example three
[0130] This embodiment is further simplified compared to the previous two embodiments. In this embodiment, each UE is set with multiple uplink power control formulas. Among these uplink power control formulas, an uplink power control formula is used as a reference, and other uplink power control formulas are added by adding a compensation value to the reference. The offset is obtained.
[0131] For example, two uplink power control formulas are set for the uplink PUCCH in the UE, and one of the uplink power control formulas is a reference, such as the uplink power control formula (1). Suppose that using this benchmark, the uplink power control formula (1) calculates the transmit power as P T1 , Then another uplink power control formula is to add a compensation value on the basis of the uplink power control formula (1), namely
[0132] P T2 =P T1 +Δ procedure . Where Δ procedure It is the compensation value, that is, the offset value. This compensation v...
