Abstract:
1. A method for assigning slotted code division multiple access time slots by a controller using a plurality of fixed beams, the method comprising for a given user: measuring a quality of each fixed beam based on a received signal power of each fixed beam; measuring a quality of each timeslot in each fixed beam based on an interference measurement of each timeslot; calculating, by the controller, a modified interference measure for each timeslot by applying a weighting factor to a timeslot interference measurement and a beam received signal power and combining a weighted timeslot interference measure with a weighted beam received power measure; ranking, by the controller, all modified interference measures; and assigning, by the controller, a plurality of timeslots to the given user, wherein the plurality of timeslots are associated with the ranked best modified interference measures and at least one of the assigned timeslots is located in a different beam than at least one of the other assigned timeslots.
