Patent ID: 7801075

Claim:
A resource allocation method of a base station using multiple antennas, the resource allocation method comprising: receiving channel quality information measured on the basis of downlink preamble or pilot signal from a terminal; determining an allocation priority for a service of the terminal; selecting a packet; determining whether available resources exist; determining an antenna weight of each of the respective multiple antennas by using a channel response; predicting a received signal to interference and noise ratio (SINR) by using a channel response between the multiple antennas and the terminal and the channel quality information; calculating a weight of each of the multiple antennas by using a first method and allocating resources by using a non-SDMA method when the available resources exist; calculating the weight of the respective antennas by using a second method that is different from the first method and allocating resources by using an SDMA method when the available resources do not exist; and allocating resources to the terminal according to the received SINR.
