Patent ID: 7953418

Claim:
A method for allocating a spatial radio resource in a communication system comprising: determining a threshold according to at least a parameter of the communication system; determining whether at least one wireless communication apparatus in the communication system is a candidate being capable of utilizing the spatial radio resource according to the threshold; scheduling priorities for a plurality of wireless communication apparatuses each being the candidate; and allocating the spatial radio resource according to the priorities of the wireless communication apparatuses each being the candidate, wherein the step of allocating the spatial radio resource comprises: according to the priorities of the priorities of the wireless communication apparatuses each being the candidate, constructing and allocating a beam to at least a wireless communication apparatus selected from the wireless communication apparatuses each being the candidate, estimating an SINR of the wireless communication apparatus being allocated the beam; and when the SINR is smaller than a predetermined value, abandoning allocating the beam to the wireless communication apparatus and then serving the wireless communication apparatus with an EDF scheduling policy.
