Abstract: A method and apparatus for controlling transmission power in a variable rate communication system is disclosed. The method disclosed provides for a closed loop power control method. A first remote station controls the transmission power of a second remote station by transmitting a rate dependent power control signal to the second remote communication station. Since only the second communication knows its transmission rate a priori, it must determine its course of action in accordance with both the received power control signal and the knowledge of its transmission rate.

Abstract: The present invention is a novel and improved method for providing broadcast short message services (SMS) in a communication network. It is an objective of the present invention to provide a method and apparatus that insures the successful transmission of the broadcast message while minimizing the impact of providing the short messaging service on overall system capacity. Messages to be broadcast to a group of users are provided by broadcast page generator (20), to a braoadcast message buffer (24). The timing of the the message transmissions is controlled by a page transmit controller (34), and the message is modulated on to an appropriate channel by modulator (26).

Abstract: A method and apparatus for controlling transmission power in a mobile communication system is disclosed. The method disclosed provides for a closed-loop power control method for variable rate transmissions. The power of transmissions is varied in accordance with the rate of the frames of data being transmitted. The transmission power between the rates can be a fixed or variable difference.

Abstract: In a method for negotiating service configuration in a communication system having at least one dedicated channel which is not shared by communication devices in the communication system, a request message indicative of a proposed service configuration is generated in a service negotiator (20). The request message is multiplexed, in a multiplexer (22) coupled to the negotiator (20), with an information data signal to produce a multiplexed signal. The multiplexed signal is encoded in an encoder (24) interposed between the multiplexer (22) and a transmitter (26) in accordance with a service configuration selected by the service negotiator (20). The multiplexed and encoded signal is transmitted by the transmitter (26) over the dedicated channel. Received signals are decoded a decoder (16) interposed between a receiver (14) and a demultiplexer (18). A response message indicative of a response to the proposed service configuration is received by the receiver (14). A determination is made by the service negotiator (20) whether the response message is indicative of a mutually acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal in accordance with the proposed service configuration if the response message is indicative of an acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal with a universal default service configuration if the response message is not indicative of an acceptable service configuration.

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: The transmitted power of a mobile telephone is established by power control bits that are transmitted in a traffic channel from a base station and that are demodulated by a rake receiver in the telephone. The rake receiver includes a plurality of demodulators that demodulate respective fingers of the traffic channel which may be caused by multipath conditions, with the power control bits from each demodulator being combined with the power control bits of the other demodulators in the rake receiver regardless of whether the demodulators are in lock with their respective fingers. The combined power control signal from a rake receiver associated with a first base station is then tested against a threshold. If the combined power is at least equal to the threshold, the combined power control signal is sent to a logic combiner. If other base stations are communicating with the mobile telephone, the combined power control signal from each of these other base stations is also sent to the logic combiner. If any power control signal commands the mobile telephone to decrease its transmitted power, it does so; otherwise, it increases its transmitted power. Alternatively, the power control bits from each demodulator in a rake receiver can be blocked if the finger energy falls below a threshold that depends on the number of fingers from the associated base station.
