Abstract
Official abstract text for this publication.
There is provided a method for adjusting a transmission power. The method may comprise: classifying, by a user equipment (UE), a plurality of cells into groups, each of which includes one or more cells belonging to the same base station; determining, by the UE, a transmission power for each group; and adjusting, by the UE, the determined transmission power for each group such that a summation of transmission powers for cells included in each group is less than or equal to a maximum transmission power configured for each group.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for adjusting a transmission power, the method comprising: classifying, by a user equipment (UE), a plurality of cells into groups, each of which includes one or more cells belonging to the same base station; determining, by the UE, a transmission power for each group; and adjusting, by the UE, the determined transmission power for each group such that a summation of transmission powers for cells included in each group is less than or equal to a maximum transmission power configured for each group. 2 . The method of claim 1 , further comprising: determining, by the UE, a transmission power for each cell; and adjusting, by the UE, the determined transmission power for each cell to be less than or equal to a maximum transmission power configured for each cell. 3 . The method of claim 2 , further comprising: adjusting, by the UE, the determined transmission power for each cell such that a summation of transmission powers for the plurality of cells is less than or equal to a maximum transmission power configured for the UE. 4 . The method of claim 1 , wherein the UE has more than one connectivity to the plurality of cells 5 . The method of claim 1 , wherein the group is defined per a physical layer entity. 6 . The method of claim 1 , wherein the maximum transmission power configured for each group is expressed as P CMAX,e . 7 . The method of claim 1 , the maximum transmission power configured for each group is calculated by amount of uplink (UL) grants. 8 . The method of claim 1 , the maximum transmission power configured for each group is calculated by amount of UL transmission power. 9 . The method of claim 1 , the maximum transmission power configured for each group is calculated by channel quality. 10 . A user equipment (UE) for controlling a transmission power, the UE comprising: a transceiver; a processor connected with the transceiver and configured to classify a plurality of cells into groups, each of which includes one or more cells belonging to the same base station, determine a transmission power for each group; and adjust the determined transmission power for each group such that a summation of transmission powers for cells included in each group is less than or equal to a maximum transmission power configured for each group. 11 . The UE of claim 10 , wherein the processor is further configured to: determine a transmission power for each cell; and adjust the determined transmission power for each cell to be less than or equal to a maximum transmission power configured for each cell. 12 . The UE of claim 11 , wherein the processor is further configured to: adjust the determined transmission power for each cell such that a summation of transmission powers for the plurality of cells is less than or equal to a maximum transmission power configured for the UE.
