Abstract
A resource allocation method in a multicarrier communication system where a base station allocates resources to a plurality of mobile stations according to feedback channel information from the mobile stations. The base station receives a resource request message from each mobile station and selects a set of mobile stations offering a maximum system gain without overlapped resources at a specific point in time based on the resource request messages from all mobile stations in the system. The requested resources and then allocated to the selected mobile stations.
Claims8
A method for allocating resources in a multicarrier communication system where a base station allocates resources to a plurality of mobile stations as a function of feedback channel information from the mobile stations, the method comprising the steps of:
- receiving a resource request message from each mobile station;
- obtaining at least one resource index set and a utilization efficiency from the resource request message;
- selecting a set of mobile stations offering a maximum system gain without overlapped resources using the at least one resource index set and the utilization efficiency at a time point when the resource request messages from each mobile station is received;
- and
- allocating, to each of the mobile stations constituting the set, resources requested by each of the mobile stations constituting the set,
- wherein the utilization efficiency is attained when resources corresponding to the at least one resource index set are allocated to each of the mobile stations constituting the set.
A method for transmitting channel information in a mobile station in a multicarrier communication system where a base station allocates resources to a plurality of mobile stations according to feedback channel information from the mobile stations, the method comprising the steps of:
- generating at least one resource index set including at least one resource considering a quality of service (QoS) requirment of an on-going service or a diversity condition;
- calculating a utilization efficiency attainable when resources corresponding to the at least one resource index set are allocated to the mobile station;
- and
- transmitting to the base station information indicating the at least one resource index set and the utilization efficiency,
- wherein the at least one resource index set and the utilization efficiency are used when the base station selects a set of mobile stations offering a maximum system gain without overlapped resources.
