Method for determining uplink transmission power in a network including a plurality of cells, and apparatus therefor

摘要

Disclosed is a method for determining uplink transmission power in a network including a plurality of cells, and an apparatus therefor. The method for a terminal to determine uplink transmission power in a network including a plurality of cells may comprise the following steps: receiving information including values of path-loss compensation factors set for each of the plurality of cells; determining uplink transmission power using the value of the path-loss compensation factor corresponding to the cell, from among the plurality of cells, in which the terminal is currently located; and a step of transmitting an uplink signal using the determined transmission power.

1. A method of determining uplink transmit power by a user equipment in a heterogeneous network including heterogeneous cells, the method comprising:
receiving information including a cell type of a cell of the heterogeneous cells, wherein the cell type indicates whether the cell of the heterogeneous cells causes interference with a neighboring cell, receiving information containing a pathloss compensation factor value corresponding to the cell type of the cell of the heterogeneous cells,
wherein the pathloss compensation factor value for the cell corresponding to the cell type is set to a full pathloss compensation factor value when the cell type indicates that the cell of the heterogeneous cells does not cause interference with the neighboring cell, andwherein the pathloss compensation factor value for the cell of the heterogeneous cells is set to a fractional pathloss compensation factor value when the cell type indicates that the cell of the heterogeneous cells causes interference with the neighboring cell; determining a physical uplink shared channel (PUSCH) transmission power using the full pathloss compensation factor value when the UE is located within the cell of the heterogeneous cells and when the cell type indicates that the cell of the heterogeneous cells does not cause interference with the neighboring cell; determining a PUSCH transmission power using the fractional pathloss compensation factor value when the UE is located within the cell of the heterogeneous cells and when the cell type indicates that the cell of the heterogeneous cells causes interference with the neighboring cell; and transmitting the PUSCH using the determined PUSCH transmission power.
