Embodiment Construction

[0043]FIG. 1 is a block diagram showing a wireless communication system.

[0044]Referring to FIG. 1, a wireless communication system 10 includes at least one base station (BS) 11. The BSs 11 provide communication services to specific geographical regions (generally referred to as cells) 15a, 15b, and 15c. The cell can be divided into a plurality of regions (referred to as sectors). A user equipment (UE) 12 may be fixed or mobile, and may be referred to as another terminology, such as a mobile station (MS), a user terminal (UT), a subscriber station (SS), a wireless device, a personal digital assistant (PDA), a wireless modem, a handheld device, etc. The BS 11 is generally a fixed station that communicates with the UE 12 and may be referred to as another terminology, such as an evolved node-B (eNB), a base transceiver system (BTS), an access point, etc.

[0045]Hereinafter, a downlink (DL) denotes communication from the BS to the UE, and an uplink (UL) denotes communication from the UE to...

Abstract

A method and an apparatus of receiving data in a wireless communication system. The method includes receiving a downlink (DL) grant on a physical downlink control channel (PDCCH) through a first DL component carrier (CC), and receiving data based on the DL grant through a second DL CC.

Description

TECHNICAL FIELD[0001]The present invention relates to wireless communications, and more particularly, to a method and an apparatus of receiving data in a wireless communication system.BACKGROUND ART[0002]In wireless communication systems, one base station (BS) generally provides services to a plurality of user equipments (UEs). The BS schedules user data for the plurality of UEs, and transmits the user data together with control information containing scheduling information for the user data. In general, a channel for carrying the control information is referred to as a control channel, and a channel for carrying the user data is referred to as a data channel. The UE finds control information of the UE by searching for the control channel, and processes data of the UE by using the control information.[0003]In order for the UE to receive user data assigned to the UE, control information for the user data on a control channel must be received. In a given bandwidth, a plurality of piec...
