Abstract
A method and an apparatus for power control in a wireless communication system are provided. When long-term evolution (LTE) and a new radio access technology (NR) are combined by means of dual connectivity (DC), etc., dynamic resource sharing can be used. Specifically, a user equipment (UE) determines whether or not uplink (UL) transmission is performed at a specific time point in a first carrier having a first processing time. When it is determined that UL transmission is not performed at the specific time point in the first carrier, the UE determines power for UL transmission at the specific time point in a second carrier having a second processing time shorter than the first processing time, on the basis of guaranteed power for the first carrier.
Claims13
A method performed by a wireless device in a wireless communication system, the method comprising:
- establishing a dual connectivity (DC) with a first carrier group (CG) and a second CG, wherein the first CG is related to a first processing time and the second CG is related to a second processing time;
- determining whether or not an uplink (UL) transmission is performed at a specific time point in the first CG;
- and
- determining a transmission power at the specific time point in the second CG based on a determination that the UL transmission is not performed at the specific time point in the first CG;
- and
- performing an UL transmission at the specific time point in the second CG based on the transmission power,
- wherein:
- in case the second processing time is longer than the first processing time, the transmission power is determined such that the transmission power is less than or equal to a maximum power of the wireless device minus a guaranteed power for the first CG;
- and
- in case the second processing time is shorter than the first processing time, the transmission power is determined such that the transmission power exceeds the maximum power of the wireless device minus the guaranteed power for the first CG.
A wireless device in a wireless communication system, the wireless device comprising:
- a memory;
- a transceiver;
- and
- at least one processor operatively coupled to the memory and the transceiver, wherein the at least one processor is configured to:
- establish a dual connectivity (DC) with a first carrier group (CG) and a second CG, wherein the first CG is related to a first processing time and the second CG is related to a second processing time,
- determine whether or not an uplink (UL) transmission is performed at a specific time point in the first CG,
- determine a transmission power at the specific time point in the second CG based on a determination that the UL transmission is not performed at the specific time point in the first CG, and
- control the transceiver to perform an UL transmission at the specific time point in the second CG based on the transmission power,
- wherein:
- in case the second processing time is longer than the first processing time, the transmission power is determined such that the transmission power is less than or equal to a maximum power of the wireless device minus a guaranteed power for the first CG;
- and
- in case the second processing time is shorter than the first processing time, the transmission power is determined such that the transmission power exceeds the maximum power of the wireless device minus the guaranteed power for the first CG.
