Method and apparatus of transmitting data in multiple RF system
First Claim
1. A method of receiving data in a multi-cell environment, the method being performed by a user equipment (UE) configured to communicate with a first cell and a second cell, the method comprising:
- receiving, from the first cell, first control information on a first downlink channel of the first cell through a physical downlink control channel (PDCCH) region;
receiving, from the first cell, second control information on a second downlink channel of the second cell through the PDCCH region;
receiving a first downlink data through the first downlink channel from the first cell, based on the first control information;
receiving a second downlink data through the second downlink channel from the second cell, based on the second control information;
determining a common uplink channel for both the first cell and the second cell; and
performing a transmission through the determined common uplink channel to only one cell of;
the first cell and the second cell,wherein the common uplink channel is used for transmitting, at the same time, both of;
information for the first cell and information for the second cell to only the only one cell of the first cell and the second cell, andwherein both of the information for the first cell and the information for the second cell transmitted on the uplink channel are related to a hybrid automatic repeat request (HARQ) operation.

Abstract
A method and an apparatus of receiving data, the method carried in a user equipment (UE) configured to communicate with a first cell and a second cell, are provided. The method includes: receiving a first downlink data through a first downlink channel from the first cell, receiving a second downlink data through a second downlink channel from the second cell, and transmitting a data on a third channel, wherein the data transmitted on the third channel is related to a HARQ operation, and wherein the third channel is used to transmit the data related to the HARQ operation with respect to both the first data and the second data which have been received from the first and second cells, respectively.

9. A user equipment, comprising:
-
a transceiver configured to communicate with a first cell and a second cell; and a processor coupled with the transceiver and configured to; receive, from the first cell, first control information on a first downlink channel of the first cell through a physical downlink control channel (PDCCH) region; receive, from the first cell, second control information on a second downlink channel of the second cell through the PDCCH region; receive a first downlink data through the first downlink channel from the first cell, based on the first control information; receive a second downlink data through the second downlink channel from the second cell, based on the second control information; determine a common uplink channel for both the first cell and the second cell; and perform a transmission through the determined common uplink channel to only one cell of;
the first cell and the second cell,wherein the common uplink channel is used for transmitting, at the same time, both of;
information for the first cell and information for the second cell to only the only one cell of the first cell and the second cell, andwherein both of the information for the first cell and the information for the second cell transmitted on the uplink channel are related to a hybrid automatic repeat request (HARD) operation. - View Dependent Claims (10, 11, 12, 13, 14)
