Abstract:
In a system comprising a plurality of base stations (BSs) and a plurality of mobile stations (MSs) communicatively couplable for establishing connections and maintaining communication channels between them, each BS and MS in the system capable of acting as a transmitting entity and a receiving entity, at least one receiving entity for maintaining an eligible set of transmitting entities with which a communication link may be established, a method for enabling at least one receiving entity to select a transmitting entity from the eligible set for establishing a communication link, comprising:receiving at a receiving entity one or more differential future activity indicator (FAI) bits from one or more transmitting entities in an eligible set of the receiving entity, the one or more FAI bits from the one or more transmitting entities providing an indication of a predicted future change in activity &Dgr;Aâ€²(t+1) relative to a current activity level for a particular transmitting entity; for one or more of the transmitting entities in the eligible set, deriving an expected change in pilot strength &Dgr;PSâ€²s(t+1) from the, one or more FAI bits, determining a current pilot strength, and computing a predicted future pilot strength for a next time period PSâ€²s(t+1) by adding the expected change in pilot strength &Dgr;PSâ€²s(t+1) to the current pilot strength; and selecting one or more transmitting entities from the one or more transmitting entities in the eligible set for establishing a communication link based on the predicted future pilot strengths PSâ€²s(t+1).
