    摘要: A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an “Active Set”. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).

In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. A memory within the mobile station includes information that would allow the mobile station to demodulate information transmitted from those base stations on the neighbor set. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).

    摘要: In a system including a resource which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.

    摘要: Reverse link busy bits are independently generated by each base station and indicate whether a base station has reached a reverse link capacity limit. A remote station combines multipath components of the reverse link busy bits in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the Active Set have reverse link capacity. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines whether to transmit based on the weighted sum of the busy signals. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines a maximum reverse link data rate based on the weighted sum of the busy signals.

A remote station combines multipath components of the reverse link busy bits in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the Active Set have reverse link capacity. In one description, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines whether to transmit based on the weighted sum of the busy signals. In another description, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines a maximum reverse link data rate based on the weighted sum of the busy signals.
