Abstract: A method and system for operation of a personal base station where the forward link of a personal base station is on the same frequency assignment as a first forward link data signal transmitted by a macro base station belonging to a cellular communication system. A first subscriber station communicates with the macro base station. The personal base station generates a second forward link data signal and communicates with a second subscriber station. The personal base station receives the first forward link data signal and combines it with its own second forward link data signal to form a combined forward link data signal. The personal base station then transmits the combined forward link data signal. The first subscriber station is able to receive and diversity combine the combined forward link data signal, improving the signal to noise ratio that would otherwise occur in the vicinity of the personal base station.

Abstract: A system and method for providing mobile switching center (MSC) initiated service negotiation in a wireless communication system. If a new call arrives for a subscriber unit while the subscriber unit is already on the traffic channel, a change in the service configuration may allow the subscriber unit to receive the new call while preserving the old call. MSC initiated service negotiation may be used to establish the change in service configuration. The MSC transmits a Change Service Command message to the base station in whose coverage area the subscriber unit is located. The Change Service Command proposes a new service configuration to accommodate both the old and the new call. The base station, subscriber unit, and MSC may interchange further messages to modify the proposed service configuration if necessary. Messages are exchanged until the base station, subscriber unit, and MSC reach an agreement regarding the new service configuration. The present invention also provides support for soft handoff. The new service configuration is presented to all target base stations involved in the soft handoff, so that the subscriber unit may make use of the new service configuration while in soft handoff.

Abstract: A media access control (MAC) layer controller can manage base layer data and enhancement layer data in a layered modulation system. The MAC layer controller can process both base layer data and enhancement layer data and map the encoded symbols to a layered modulation constellation when both are present. If data for one of the layers terminates, then the MAC layer controller can generate and supply predetermined stuffing data to the layer lacking additional data. The MAC layer controller can send a control signal to the physical layer hardware to cause the hardware to map the layered signals having the stuffing data to a modified signal constellation. The MAC controller can also generate an overhead message that indicates the occurrence of the stuffing data. The receiver can receive the overhead message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation.
