Method and apparatus for transmitting data in wireless communication system
First Claim
1. A method for transmitting data by a mobile station of a wireless communication system, the method comprising:
- transmitting, if power consumption of the mobile station is higher than a limitation of power consumption, notification information to a base station, the notification information indicating that power consumption of the mobile station is higher than the limitation of power consumption;
receiving uplink data transmission scheduling generated using the notification information, from the base station;
transmitting, if power consumption of the mobile station is higher than the limitation of power consumption, first data to the base station with power higher than the limitation of power consumption using power supplied from a primary power-supply unit and a storage unit during a first time according to the received uplink data transmission scheduling; and
charging the storage unit using the primary power-supply unit during a second time,wherein the limitation of power consumption indicates maximum power amount capable of being normally supplied from the primary power-supply unit.

Abstract
A method and apparatus for transmitting data in a wireless communication system are disclosed, which transmit uplink data in consideration of mobile station (MS) consumption power such that a UE can be stably operated at a cell edge. A method for transmitting data by a mobile station (MS) of a wireless communication system includes transmitting, if MS power consumption is higher than limitation of power consumption, data to a base station (BS) with power higher than the limitation of power consumption using power supplied from a primary power-supply unit and a storage unit during a first time, and charging the storage unit using the primary power-supply unit during a second time, wherein the limitation of power consumption indicates maximum power amount capable of being normally supplied from the primary power-supply unit.

9. A mobile station for use in a wireless communication system, the mobile station comprising:
-
a wireless communication unit configured to communicate with a base station; a primary power-supply unit configured to provide a power required for operating of the mobile station; a storage unit that is charged using power of the primary power-supply unit when power consumption of the mobile station is equal to or less than a limitation of power consumption; and a controller configured to; if the power consumption of the mobile station is higher than the limitation of power consumption, control the wireless communication unit to transmit notification information to a base station, the notification information indicating that power consumption of the primary power-supply unit is higher than the limitation of power consumption; receive uplink data transmission scheduling generated using the notification information from the base station via the wireless communication unit; if the power consumption of the mobile station is higher than the limitation of power consumption, control the wireless communication unit to transmit first data to the base station with power higher than the limitation of power consumption using power supplied from the primary power-supply unit and the storage unit during a first time according to the received uplink data transmission scheduling; and control the primary power-supply unit to charge the storage unit during a second time, wherein the limitation of power consumption indicates maximum power amount capable of being normally supplied from the primary power-supply unit.
