What is open loop power control in LTE?
In Open Loop Control, UE determines its Transmission Power by its own Power Setting Algorithm. This Power Setting Algorithm takes in many inputs, but all of these inputs are from UE internal setting or measurement data by the UE. It means UE Transmission Power is controled by some feedback input from eNB.
What is power control in cellular communication system?
Power control, broadly speaking, is the intelligent selection of transmitter power output in a communication system to achieve good performance within the system. Power control algorithms are used in many contexts, including cellular networks, sensor networks, wireless LANs, and DSL modems.
Is there power control in LTE?
The LTE power control mechanism constitutes of a closed loop component operating around an open loop point of operation. Specifically, the open loop component has a parameterized fractional path loss compensation factor, enabling a trade-off between cell edge bitrate and cell capacity.
What do you mean by power control?
In telecommunications, power control refers to the process of controlling the power of a transmitter to achieve better communication signal or overall quality of service. It is mainly used to control the transmitting power of a communication device to achieve better performance.
Why power control is important in cellular network?
Power control is essentially needed to solve the near-far problem. The main idea to reduce the near-far problem, is to achieve the same power level received by all mobiles to the base station. Each received power must be at least level, so that it allows the link to meet the requirements of the system such that Eb/N0.
What is Plmn LTE?
PLMN stands for Public Land Mobile Network. The LTE compliant UE is responsible for selecting a PLMN for subsequent cell selection. A PLMN is identified by its PLMN identity broadcast within SIB-1. Operator controlled PLMN selector with access technology allows the operator to prioritise the PLMN and access technology.
Where does power control take place in LTE?
In LTE , Power control takes place both in Downlink and Uplink. They way it takes place in Downlink and Uplink will become evident in a little bit , as we go further down the discussion. However, a picture is worth thousand words. Therefore the picture below should explain you on Which channels in DL and UL , power control takes place.
How is power control used in LTE uplink?
In case of Uplink in LTE, Power control is used. As the battery of the phone (UE) is power limited compared to base station power in the DL. Uplink power control is used mainly for the following two reasons. limit intracell and intercell interference
What can a switched rack PDU do for You?
Switched Rack PDUs enable advanced, customizable power control and active monitoring for datacenter and edge environments. Remote outlet level control allows on/off power cycling to remotely reboot equipment and restrict unauthorized use of individual outlets to reduce downtime.
What does switching feature on APC rack do?
The Switching feature enables advanced, user-customizable power control. The Switching feature provides remote power on/off outlet level controls for power cycling to remotely reboot equipment and restrict unauthorized use of individual outlets.
