Abstract
Some embodiments herein relate to method in a user equipment for determining a transmit power to be used by the user equipment when transmitting in a radio communications network, which user equipment is served by a radio network node in the radio communications network. The user equipment receives, from the radio network node, an indication indicating a set of power control parameters out of multiple sets of power control parameters, which multiple sets of power control parameters are stored at the user equipment. The user equipment determines a transmit power based on the indicated set of power control parameters.
Claims20
A method in a user equipment for determining a transmit power to be used by the user equipment when transmitting over a Physical Uplink Shared Channel (PUSCH) in a radio communications network, wherein the user equipment is served by a radio network node in the radio communications network, the method comprising:
- receiving, from the radio network node, an indication indicating a set of power control parameters out of multiple sets of power control parameters and an accumulative power command, wherein the multiple sets of power control parameters are stored at the user equipment;
- and
- adjusting the transmit power for a PUSCH transmission based on the indicated set of power control parameters,
- wherein adjusting the transmit power comprises accumulating the accumulative power command with a previously used power command, and wherein different accumulations are done for different sets of power control parameters.
A method in a radio network node for controlling a transmit power of a user equipment when transmitting over a Physical Uplink Shared Channel (PUSCH) in a radio communications network, wherein the radio network node serves the user equipment in the radio communications network, the method comprising:
- determining a set of power control parameters to be used by the user equipment for determining transmit power of the user equipment;
- and
- transmitting an indication to the user equipment, wherein the indication indicates the set of power control parameters out of multiple sets of power control parameters stored at the user equipment and an accumulative power command, thereby controlling the user equipment to adjust a transmit power for a PUSCH transmission based on the indicated set of power control parameters,
- wherein to adjust the transmit power, the user equipment is controlled to accumulate the accumulative power command with a previously used power command, and wherein different accumulations are done for different sets of power control parameters.
A user equipment for determining a transmit power to be used by the user equipment when transmitting over a Physical Uplink Shared Channel (PUSCH) in a radio communications network, wherein the user equipment is configured to be served by a radio network node in the radio communications network, wherein the user equipment comprises:
- a memory configured to have multiple sets of power control parameters stored thereon;
- a receiver configured to receive, from the radio network node, an indication indicating a set of power control parameters out of the stored multiple sets of power control parameters and an accumulative power command;
- a determining circuit configured to adjust a transmit power for a PUSCH transmission based on the indicated set of power control parameters,
- wherein to adjust the transmit power, the determining circuit is configured to accumulate the accumulative power command with a previously used power command, and wherein different accumulations are done for different sets of power control parameters.
