Patent ID: 8244266

Claim:
A scheduling method of a Base Station (BS) in a cellular system using a wired Relay Station (RS), comprising: collecting by the base station Channel Quality Information (CQIs) of all Mobile Stations (MSs) within a cell of a plurality of cells and the BS receiving CQIs via at least one respective wired RS per cell that is wired to the BS and receives data in resource segments of a frame, and each of said at least one respective wired RS per cell communicates wirelessly with the MSs within a respective cell of the plurality of cells; calculating a transmittable data amount for each of the MSs according to the CQIs; and selecting an MS having a highest PF metric and allocating resources to the selected MS, the PF metric being defined as: PF ⁢ ⁢ metric ⁢ ⁢ for ⁢ ⁢ ith ⁢ ⁢ M . ⁢ S = R i ⁡ ( t ) R i ⁡ ( t ) ( 4 ) where i denotes the index of an MS, R i (t) denotes a data rate available to an i th MS in a scheduling time period t, and R i (t) denotes the average data rate of data transmitted to the i th MS from a previous time period to the scheduling time period t: and the MS having the highest PF metric being expressed as: i * = arg ⁢ ⁢ max ⁢ { R i ⁡ ( t ) R i ⁡ ( t ) } ( 5 ) where i* denotes the selected MS in the scheduling time period t; and wherein the RS is wired to the BS via optical fiber.
