    Abstract: PROBLEM TO BE SOLVED: To reduce the probability of dropped calls during inter-system hard handoff in a radio communication system. SOLUTION: When a hard handoff attempt is unsuccessful, the mobile station M3 will return to the original system S1 with information which the communication system uses to assist in the performance of future handoff attempts. Alternatively, with no handoff attempt made, the mobile station M3 monitors the destination system S2 then returns to the original system S1 with information used to assist in subsequent handoff attempts. The information returned from monitoring consists of results of a search for one or more pilots given at offsets in a specific list provided to the mobile station by the base station or a set of offsets based on a predetermined search algorithm.

    Abstract: PROBLEM TO BE SOLVED: To improve retransmission through-put with less energy. SOLUTION: When a wrong packet is received, an efficient data transmission by symbol accumulation is implemented using the same frame as a new packet concurrently at a lower energy-per-bit level. A destination device receives data transmission and re-transmission, demodulates the signal, and divides the signal into a new packet and a re-transmission packet. The destination device accumulates the energy of the retransmitted packet with the energy already accumulated for the packet received in error and decodes the accumulated packet. The accumulation of the additional energy provided by the subsequent retransmissions improves the probability of a correct decoding. The throughput rate can be improved since the packet received in error is retransmitted concurrently with the transmission of the new data packet. The capacity is maximized since the retransmission of the packet received in error is at a lower energy level than that of the new packet. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for handoff, in a broadcast communication system.
    SOLUTION: A subscriber assisted handoff is difficult to be practical in a broadcast communication system due to, for example, a high signaling load, or a difficulty in synchronizing the broadcast transmission. Meanwhile, the small number of broadcast channels enables a subscriber station to autonomously perform handoff. To streamline the autonomous handoff decision process, rules for transitioning among several distinct sets of pilot identifiers are defined. To fully integrate broadcast services with the services provided by the cellular telephone systems in a subscriber environment, methods for various handoff scenarios are analyzed.

    Abstract: PROBLEM TO BE SOLVED: To maintain the throughput rate of a communication system.
    SOLUTION: An efficient retransmission of data using symbol accumulation, wherein the packet received in error is retransmitted at a lower energy-per-bit level concurrently, in the same frame as with the new packet. The destination device receives the data transmission and retransmission, demodulate the signal, and separates the received data into the new and retransmitted packet. The destination device then accumulates the energy of the retransmitted packet with the energy already accumulated for the packet received in error and decodes the accumulated packet. The accumulation of the additional energy provided by the subsequent retransmissions improves the probability of a correct decoding. The throughput rate can be improved, since the packet received in error is retransmitted concurrently with the transmission of the new data packet. The capacity is maximized, since the retransmission of the packet received in error is at a lower energy level than that of the new packet.

    Abstract: PROBLEM TO BE SOLVED: To coordinate time required by a mobile station to search for an alternative system used for performing hard hand-off.
    SOLUTION: The mobile station receives a command instructing the mobile station as for tuning at an alternative frequency to search for the display of the presence of an alternative system. A predetermined time is defined with respect to a reference point of time common between a starting base station and the mobile station. The mobile station executes search only during the predetermined time synchronously with the alternative frequency. Further, the mobile station coordinates a transmission report indicating the result of searching for the alternative system so that the report can be transmitted from the mobile station when the mobile station is tuned at the starting frequency.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling transmission power of a base station in soft handoff.
    SOLUTION: Transmitters 20, 32 are attached to a separated control unit 12 through communication links. The control unit 12 then derives the most likely command stream to be sent to a base station. In a second exemplary embodiment, the control unit periodically receives the final or average transmission level in a period and an aggregate quality measure for the feedback during a period from each of the transmitters. The control unit 12 determines the aligned power level and transmits a message indicative of the aligned power level to the transmitters. In a third exemplary embodiment, the transmitters 20, 32 send a message indicative of the transmission power of transmission to the receiver. The control unit 12 determines the aligned transmit power, based on the current transmission power.
