Patent ID: 7702336

Claim:
A method comprising: assigning a co-spatial constraint to each of a plurality of conventional traffic communications channels of a base station, the channel co-spatial constraints comprising a limitation on the quantity of radios that can share the respective channel using spatial division multiple access; receiving a request from a user terminal to communicate using a traffic communication channel of the base station; measuring a quality parameter of the request received from the user terminal; deriving a co-spatial constraint for the user terminal based on the quality parameter, the user terminal co-spatial constraint comprising a limitation on the quantity of additional radios with which the user can share a conventional traffic communications channel using spatial division multiple access; assigning the user terminal co-spatial constraint to the user terminal; and assigning the user terminal to one of the plurality of traffic communication channels having a channel co-spatial constraint that is no less than the user terminal co-spatial constraint and that has no more assigned radios than permitted by the channel co-spatial constraint.
