  • Power Control to Compensate Interference Level Changes
    Publication number: 20150094112
    Abstract: A user equipment (UE) determines a first transmission power for a control channel using closed loop power control with a wireless network; and determines a second transmission power for the control channel. For transmission time intervals (TTIs) in which the UE is transmitting the control channel and also transmitting data on a data channel, the UE selects the second transmission power for transmitting the control channel. For TTIs in which the UE is transmitting the control channel but not also transmitting data on the data channel, the UE selects the first transmission power for transmitting the control channel. Three distinct embodiments are shown for these two transmission powers, and also quantitative data is shown that in a HSPA system this technique reduces inter-user interference at least at high SINR.
