Abstract
Method, carried out in a radio terminal (130), for configuring uplink output power of radio transmission from the radio terminal, comprising determining (402) a demand power reduction (P-MPR1) based on a maximum power level associated with a first uplink duty cycle (UDC1); transmitting (403), to a radio network node (120), an indication (233) of the demand power reduction; receiving (404), from the network node, an indication (253) of a target power reduction (P-MPR2) associated with an actual uplink duty cycle (UDC2); and configuring (406) the output power based on the target power reduction.
Claims26
A method, carried out in a radio network node, for configuring uplink output power of radio transmission from a radio terminal, said method comprising:
- determining a demand power reduction based on a maximum power level associated with a first uplink duty cycle;
- transmitting, to a radio network node, an indication of the demand power reduction;
- and
- receiving, from the network node, an indication of an actual uplink duty cycle and of a target power reduction associated with the actual uplink duty cycle;
- wherein the receiving comprises receiving, from the network node, network scheduling for an uplink transmission of the radio terminal in accordance with the actual uplink duty cycle;
- and
- configuring the output power based on the target power reduction.
A method, carried out in a radio network node, for configuring uplink output power of radio transmission from a radio terminal, comprising
- receiving, from the radio terminal, an indication of a demand power reduction based on a maximum power level, associated with uplink transmission with a first uplink duty cycle;
- determining a target power reduction for the radio terminal;
- determining an actual uplink duty cycle associated with the target power reduction associated with the target power reduction;
- transmitting, to the radio terminal, an indication of the determined target power reduction to apply by the radio terminal for configuring the output power;
- and
- wherein the transmitting comprises scheduling uplink transmission from the terminal in accordance with the actual uplink duty cycle.
A radio terminal, comprising:
- a radio transceiver,
- logic configured to communicate data, via the radio transceiver, with a radio network node, wherein the logic is further configured to
- determine a demand power reduction based on a maximum power level, associated with a first uplink duty cycle;
- transmit, to a radio network node, an indication of the demand power reduction;
- receive, from the network node, an indication of a target power reduction and an actual uplink duty cycle associated with the target power reduction;
- and
- receive, from the network node, network scheduling for an uplink transmission of the radio terminal in accordance with the actual uplink duty cycle;
- and
- configure the output power based on the target power reduction.
A radio network node, for configuring uplink output power of radio transmission from a radio terminal, comprising:
- a radio transceiver,
- logic configured to communicate data via the radio transceiver, wherein the logic is configured to
- receive, from the radio terminal, an indication of a demand power reduction based on a maximum power level, associated with uplink transmission with a first uplink duty cycle;
- determine a target power reduction for the radio terminal;
- transmit, to the radio terminal, an indication of the target power reduction to apply by the radio terminal for configuring the output power;
- determine, an actual uplink duty cycle associate with the target power reduction;
- and
- schedule, an uplink transmission from the terminal in accordance with the actual uplink duty cycle.
