Radio access network sharing

摘要

A method implemented in an apparatus used in a radio access network (RAN) sharing system including a plurality of basestations is disclosed. The method includes 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. Other methods, apparatuses, and systems also are disclosed.

1. 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:djb=∑i∈Qjb⁢min⁡(β⁢⁢Ai,Si)T×Ri, where dbj is the resource requirement or demand, Qbj is a set of flows that belong to entity j at basestation b, Ai and Si 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 Ri is the average number of bits per resource block derived from per-flow MCS information.
