Abstract

A method for communicating with a network by a terminal in a wireless communication system, wherein the terminal receives, from the network, signaling information representing a transmission period and a time offset for uplink transmission of a feedback information, and determines a time to transmit the feedback information based on the transmission period and the time offset. The terminal transmits the feedback information to the network based on the determined time.

First claim

What is claimed is:

1. A method for communicating with a base station, by a terminal, in a wireless communication system, the method comprising the steps of:
receiving, from the base station, signaling information representing a transmission period and a time offset for uplink transmission of feedback information, the transmission period being configured from among a plurality of transmission periods corresponding to different lengths represented by a number of resource allocation units based on table information on the different lengths, the transmission period depending on a reception power of an uplink control channel;
determining a time to transmit the feedback information, based on the transmission period and the time offset, the transmission period used for periodic transmission of channel state information on the uplink control channel; and
transmitting the feedback information to the base station at the determined time,
wherein the feedback information includes the channel state information associated with downlink data transmission of the base station, and
wherein the transmission period denotes a time interval between two discrete transmissions of the channel state information.

2. The method of claim 1 , wherein the feedback information further includes control information associated with the base station.

3. The method of claim 1 , wherein the base station receives the feedback information from a plurality of terminals.

4. A terminal for communicating with a base station in a wireless communication system, the terminal comprising:
a receiver configured to receive signaling information from the base station;
a transmitter configured to transmit feedback information to the base station; and
at least one processor configured to identify a transmission period and a time offset for uplink transmission of the feedback information from the signaling information, the transmission period being configured from among a plurality of transmission periods corresponding to different lengths represented by a number of resource allocation units based on table information on the different lengths, the transmission period depending on a reception power of an uplink control channel, to determine a time to transmit the feedback information based on the transmission period and the time offset, the transmission period used for periodic transmission of channel state information on the uplink control channel, and to control the transmitter to transmit the feedback information at the determined time,
wherein the feedback information includes the channel state information associated with downlink data transmission of the base station, and
wherein the transmission period denotes a time interval between two discrete transmissions of the channel state information.

5. The terminal of claim 4 , wherein the feedback information further includes control information associated with the base station.

6. The terminal of claim 4 , wherein the base station receives the feedback information from a plurality of terminals.

7. A method for communicating with a plurality of terminals, by a base station, in a wireless communication system, the method comprising the steps of:
transmitting, by the base station, to each terminal, signaling information representing a transmission period and a time offset for uplink transmission of feedback information, the transmission period used for periodic transmission of channel state information on an uplink control channel, the transmission period being configured from among a plurality of transmission periods corresponding to different lengths represented by a number of resource allocation units based on table information on the different lengths, the transmission period depending on a reception power of the uplink control channel;
receiving the feedback information which is transmitted from each terminal according to the transmission period and the time offset; and
performing downlink transmission for each terminal based on the feedback information,
wherein the feedback information includes the channel state information associated with downlink data transmission of the base station, and
wherein the transmission period denotes a time interval between two discrete transmissions of the channel state information.

8. The method of claim 7 , wherein the feedback information further includes control information associated with the base station.

9. A base station for communicating with a plurality of terminals in a wireless communication system, the base station comprising:
a transmitter configured to transmit signaling information to each of the plurality of terminals;
a receiver configured to receive feedback information from each of the plurality of terminals; and
at least one processor configured to control the transmitter to transmit the signaling information representing a transmission period and a time offset for uplink transmission of the feedback information, the transmission period used for periodic transmission of channel state information on an uplink control channel, the transmission period being configured from among a plurality of transmission periods corresponding to different lengths represented by a number of resource allocation units based on table information on the different lengths, the transmission period depending on a reception power of the uplink control channel, to control the receiver to receive the feedback information which is transmitted from each of the plurality of terminals according to the transmission period and the time offset, and to perform downlink transmission for each of the plurality of terminals, based on the feedback information,
wherein the feedback information includes the channel state information associated with downlink data transmission of the base station, and
wherein the transmission period denotes a time interval between two discrete transmissions of the channel state information.

10. The base station of claim 9 , wherein the feedback information further includes control information associated with the base station.
