Method of dynamic resource allocations in wireless systems
View Patent ↗A method of dynamic resource allocations in wireless network is disclosed. The method provides that a base station in the network allocates resources to users independently of other base stations and without resource planning. Resource allocations are done based at least in part on a local optimization objective and a channel quality indicator from one or more users, and result in efficient resource reuse.
1. A method of managing sub-band resources in a wireless network including a plurality of base stations each corresponding to one or more reception areas, the method comprising:
adaptively allocating, at each of the plurality of base stations, one or more sub-band resources to one or more mobile devices in corresponding reception areas based on indications of one or more power adjustments received from the one or more mobile devices, wherein adaptively allocating includes:
determining whether a sub-band resource index corresponds to a maximum slot index;
determining whether the sub-band resource index corresponds to a first maximum value when the sub-band resource index corresponds to the maximum slot index;
determining a mobile device of the one or more mobile devices for maximizing current usage of a utility of a base station of the plurality of base stations based on the first maximum value; and
determining a second maximum value based on the current usage of the utility of the base station.
2. The method of claim 1 , further comprising:
estimating a sub-band resource rate, wherein the sub-band resource rate is available to the one or more mobile device users.
3. The method of claim 2 , wherein estimating further comprises:
computing by a base station an estimate of the sub-band resource rate as a function of an average pilot signal-to-interference-and-noise ratios.
4. The method of claim 1 wherein the plurality of base stations comprise sectors, and wherein each of the sectors maintains a maximum attainable utility of power levels for one or more sub-band resources.
