Patent ID: 8874125

Claim:
A method implemented in an apparatus used in a radio access network (RAN) sharing system including a plurality of basestations, the method comprising: estimating resource requirement or demand of one or more entities in each base station according to feedback from the plurality of basestations; computing resource allocation for said one or more entities; and enforcing the computed resource allocation using basestation-level virtualization, wherein the estimation comprises: computing the resource requirement or demand for entity j at base station b using the following formula: d j b = ∑ i ∈ Q j b ⁢ min ⁡ ( β ⁢ ⁢ A i , S i ) T × R i , where d b j is the resource requirement or demand, Q b j is a set of flows that belong to entity j at basestation b, A i and S i are the arrival rate and maximum sustained rate, respectively, of flow i that belongs to entity j, β is a parameter, T is the total number of resource blocks in a base station in one second, and R i is the average number of bits per resource block derived from per-flow MCS information.
