Method and base station for power control in TDMA radio system
First Claim
1. A method for transmit power control in a TDMA multicarrier radio system communicating over multiple time slots assigned to given user terminals, comprising:
- allocating a respective transmit power level for at least one of a plurality of user terminals;
calculating the sum of transmit powers on each carrier for each time slot separately;
allocating the time slots and carriers for connections to the user terminals in such a way that the sum of transmit power levels in each time slot is minimized.
