Radio Nodes and Methods for Power Control of Transmit Symbols based on Their Symbol Type while Taking Into Account of Radio Node Power Headroom

A method performed by a first radio node for controlling a transmission power level for transmitting one or more symbols in a channel to a second radio node in a wireless communications network, the method comprising:

• obtaining, for the respective one or more symbols, one or more transmission power parameters, wherein the one or more transmission power parameters are related to the respective symbol type of the respective one or more symbols to be transmitted;
• determining, based on the one or more transmission power parameters, a respective transmission power level to be used for transmitting the respective one or more symbols, wherein the respective transmission power level is determined taking an available power headroom in the first radio node into account;
• and
• transmitting the one or more symbols with the determined respective transmission power level in the channel to the second radio node.

A first radio node configured to control a transmission power level for transmitting one or more symbols in a channel to a second radio node in a wireless communications network, the first radio node comprising:

• radio transceiver circuitry;
• and
• processing circuitry operatively associated with the radio transceiver circuitry and configured to:
• obtain, for the respective one or more symbols, one or more transmission power parameters, wherein the one or more transmission power parameters are adapted to be related to the respective symbol type of the respective one or more symbols to be transmitted,
• determine, based on the one or more transmission power parameters, a respective transmission power level to be used for transmitting the respective one or more symbols, wherein the respective transmission power levels are determined taking an available power headroom in the first radio node into account, and
• transmit the one or more symbols with the determined respective transmission power level in the channel to the second radio node.
