Description

The Poewr control method of Physical Uplink Control Channel and device

Technical field

The present invention relates to moving communicating field, particularly relate to a kind of Poewr control method and device of Physical Uplink Control Channel.

Background technology

At 3GPP LTE (The 3rd Generation Partnership Project Long Term Evolution, third generation partner program Long Term Evolution) in the system, uplink power control (uplink power control, abbreviate uplink power control or power control as) be used to control the transmitting power of uplink physical channel (uplink physical channel), with the path loss and the shade of compensate for channel, and suppress presence of intercell interference.Wherein, the uplink physical channel of uplink power control control comprises Physical Uplink Shared Channel (Physical Uplink SharedChannel, PUSCH), Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) and measuring reference signals (Sounding Reference Signal, SRS).The control mode that the LTE uplink power control adopts open loop (open loop) and closed loop (closed loop) to combine.

In the LTE system, (User Equipment, UE) transmitting power of the Physical Uplink Control Channel PUCCH on subframe (subframe) i is defined as subscriber equipment

P _PUCCH(i)＝min{P _CMAX，P _{0_PUCCH}+PL+h(n _CQI，n _HARQ)+Δ _{F_PUCCH}(F)+g(i)}[dBm]

Wherein, g (i) is called the current power control adjustment state (the current PUCCHpower control adjustment state) of PUCCH, is shown below:
