Apparatus and method for operating frequency resources in a mobile communication system
First Claim
1. A method of transmitting and receiving data using Channel State Information (CSI) in a mobile communication system, comprising the steps of:
- setting the CSI of a Mobile Station (MS) to an initial CSI and transmitting data to the MS according to the initial CSI by a Base Station (BS);
transmitting a downlink CSI to the BS by the MS;
grouping the MS based on the downlink CSI by the BS; and
transmitting data to the MS according to a hopping pattern for the group of the MS among hopping patterns preset for predetermined groups by the BS.

Abstract
A frequency resource operating apparatus and method for transmitting and receiving data at a different hopping pattern speed according to a CSI in a BWA communication system are provided. In a method of transmitting and receiving data using CSI in a mobile communication system, a BS sets the CSI of an MS to an initial CSI and sends data to the MS according to the initial CSI. The MS sends a downlink CSI to the BS. The BS groups the MS based on the downlink CSI and sends data to the MS according to a hopping pattern for the group of the MS among hopping patterns preset for predetermined groups.

11. A method of transmitting and receiving data using Channel State Information (CSI) in a mobile communication system, comprising the steps of:
-
receiving a random access signal from at least one Mobile Station (MS) by a Base Station (BS);
determining the CSI of the at least one MS to be an initial CSI and allocating frequency resources to the at least one MS based on the initial CSI by the BS;
sending data using the allocated frequency resources to the BS by the at least one MS;
measuring the CSI of the at least one MS operating based on the initial CSI by the BS;
regrouping the at least one MS according to the measured CSI by the BS; and
allocating different frequency resources to groups according to the CSIs of the groups and sending data to the at least one MS by the BS. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A system for transmitting and receiving data using Channel State Information (CSI) in a mobile communication system, comprising:
-
a Base Station (BS) for grouping Mobile Stations (MSs) into predetermined groups according to the CSIs of the MSs, applying different hopping patterns to the groups according to the CSIs of the groups, and transmitting and receiving data to and from the MSs of the groups according to the hopping patterns applied to the groups; and
an MS for transmitting and receiving data to and from the BS according to a hopping pattern determined for the MS by the BS. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
