Abstract
A method and apparatus for calculating an initial transmission power in a mobile telecommunications system is disclosed, the system comprising a network of a plurality of cells and at least one user equipment device. The user equipment device receives broadcast system information, and measures a signal power. An initial transmission power is calculated in a lowest logical layer of the system defined as a protocol stack, using the received information and measured power.
Claims14
A method for calculating a transmission power in a user equipment configured for use in a mobile telecommunications system, said user equipment comprising a protocol stack including a lower physical layer L1, the method comprising:
- at a logical layer higher than L1,
- calculating a first power value by the user equipment;
- submitting said first power value to the lower physical layer L1;
- and
- in the lower physical layer L1,
- calculating the transmission power from said first power value.
A user equipment for use in a mobile telecommunications system, said user equipment comprising a protocol stack including a lower physical layer L1, the user equipment configured to:
- at a logical layer higher than L1, calculate a first power value and submit said first power value to the lower physical layer L1;
- and
- in the lower physical layer L1, calculate the transmission power from said first power value.
A non-transistory computer readable medium having instructions for causing a processor to execute a method for calculating a transmission power for a user equipment having a protocol stack including a lower physical layer L1, the method comprising:
- calculating, at a logical layer higher than L1, a first power value and submit said first power value to the lower physical layer L1;
- and
- calculating, in the lower physical layer L1, the transmission power from said first power value.
A user equipment for use in a mobile telecommunications system, wherein said user equipment comprises a protocol stack including a lower physical layer L1, the user equipment comprising :
- means for calculating, at a logical layer higher than L1, a first power value and submit said first power value to the lower physical layer L1;
- and
- means for calculating, in the lower physical layer L1, the transmission power from said first power value.
