Channel assignment based on spatial strategies in a wireless network using adaptive antenna arrays
First Claim
1. A method comprising:
- determining a radio channel signal quality parameter for a plurality of user terminals of a radio communications system;
assigning a co-spatial constraint to each of the user terminals based on the parameter, the user terminal co-spatial constraints comprising a limitation on the quantity of other user terminals with which the respective user terminal can share a traffic communications channel of the radio communications system using spatial division multiple access expressed as a number of radios; and
assigning the user terminals each to one of a plurality of traffic communication channels based on the assigned user terminal co-spatial constraint so that the number of radios sharing at least one channel does not exceed the co-spatial constraint number of radios assigned to any one of the radios sharing the channel.

Abstract
Channels are assigned based on co-spatial constraints in wireless network using spatial division multiple access. In one example, the invention includes assigning a co-spatial constraint to each of a plurality of conventional traffic communications channels of a base station, and receiving a request from a user terminal to communicate using a traffic communication channel of the base station. The invention further includes measuring a quality parameter of the request deriving a co-spatial constraint for the user terminal, assigning the user terminal co-spatial constraint to the user terminal, and assigning the user terminal to a 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.
