Abstract
A method for calculating a RoT threshold value in a communication system in which user terminals communicate with a base transceiver station, comprising the steps of providing a RoT minimum, maximum and margin, acquiring the maximum nominal transmit power of each user terminal, detecting the transmitted power of each user terminal, calculating the power difference between the maximum nominal transmit power and the transmitted power for each user terminal, and processing this power difference calculated for each user terminal, the RoT margin and the minimum and maximum RoT threshold to calculate the RoT threshold value.
Claims16
A method for calculating a Rise-over-Thermal (RoT) threshold value in a communication system in which a plurality of user terminals communicate with a base transceiver station, said method including the steps of:
- a) providing a minimum RoT threshold and a maximum RoT threshold,
- b) providing a RoT margin,
- c) acquiring the maximum nominal transmit power of each user terminal of said plurality of user terminals,
- d) detecting the power transmitted from each user terminal,
- e) calculating, for each user terminal, the power difference between the maximum nominal transmit power and the transmitted power,
- f) processing the calculated power difference for each user terminal, the RoT margin and the minimum and maximum RoT threshold values to calculate a RoT threshold value.
A communication system for calculating a Rise-over-Thermal (RoT) threshold value, comprising:
- a plurality of user terminals,
- a plurality of cells, each comprising a base station subsystem adapted to provide communication services to each user terminal located in its respective cell, each base station subsystem comprising one or more base transceiver stations,
- a base station controller in signal communication with each base station subsystem, wherein
- said base station controller comprises:
- storage means designed for storing a minimum RoT threshold value, a maximum RoT threshold value, and a RoT margin and the maximum nominal transmit power of each user terminal, and
- processing means designed for:
- detecting the power transmitted from each user terminal,
- calculating, for each user terminal, the power difference between the maximum nominal transmit power and the transmitted power,
- processing the calculated power difference for each user terminal, the RoT margin and the minimum and maximum RoT threshold values to calculate a RoT threshold value.
