Abstract
Disclosed is a method and apparatus for allocating a bandwidth in a communication system. The method includes the steps of checking the number of mobile stations that fall within a cell under the control of an relay station and have data to be transmitted to a base station, determining a bandwidth allocation period for data transmission corresponding to the checked number of mobile stations, and transmitting a bandwidth allocation message at intervals of the determined bandwidth allocation period.
Claims20
A method of allocating a bandwidth in a communication system, the method comprising:
- determining, at a relay station, a number of mobile stations that fall within a cell of the relay station and have data to be transmitted to a base station;
- determining, at the relay station, a bandwidth allocation period for data transmission based on the determined number of mobile stations, wherein determining the bandwidth allocation period comprises:
- when the determined number of mobile stations is greater than an existing number of mobile stations, determining the bandwidth allocation period by decreasing a previous bandwidth allocation period;
- and
- when the determined number of mobile stations is less than the existing number of mobile stations, determining the bandwidth allocation period by increasing the previous bandwidth allocation period;
- and
- receiving, at the relay station, a bandwidth allocation message according to the determined bandwidth allocation period.
A system for allocating a bandwidth in a communication system, the system comprising:
- a relay station configured to determine a bandwidth allocation period for data transmission based on a number of mobile stations that fall within a cell of the relay station and have data to be transmitted to a base station and receive a bandwidth allocation message according to the determined bandwidth allocation period, wherein the relay station is further configured to determine the bandwidth allocation period by decreasing a previous bandwidth allocation period when the determined number of mobile stations is greater than an existing number of mobile stations, and determine the bandwidth allocation period by increasing the previous bandwidth allocation period when the determined number of mobile stations is less than the existing number of mobile stations.
