摘要： An acknowledgement method in a wireless communication system. Initially, a reverse supplemental channel (R-SCH) frame is received at a base station. The base station then transmits an acknowledgement (ACK) signal if quality of the received R-SCH frame is indicated as being good. A negative acknowledgement (NAK) signal is transmitted only if the received data frame is indicated as being bad but has enough energy such that, if combined with energy from retransmission of the data frame, it would be sufficient to permit correct decoding of the data frame. If the best base station is known, the acknowledgement method may reverse the transmission of the acknowledgement signals for the best base station so that only NAK signal is sent. A positive acknowledgement is assumed in the absence of an acknowledgement. This is done to minimize the transmit power requirements.

摘要： A mobile station comprising a receiver (590) for receiving signals, including parameter data (OFNLM) of an origination system (S1) representing a parameter value (MIN_RX_PWR, MIN_TOT_PILOT) of signals of a different, destination system (S2); a controller (52) coupled to the receiver for controlling the receiver to change between receiving signals of the origination communication system (S1) and receiving signals of the destination communication system (S2); and parameter measuring means (530, 540) for measuring a parameter of received signals of the destination communication system (S2), the parameter measuring means being coupled to the controller (520) to provide measured parameter data thereto. The received parameter data comprises control data (RETURN_IF_FAIL) indicating whether the mobile station should receive again signals of the origination communication system (S1). The controller (520) is arranged to operate by comparing the measured parameter with received parameter values (MIN_RX_PWR, MIN_TOT_PILOT), and controlling the receiver to receive again signals of the origination communication system (S1) based on the comparison of the measured parameter data and the received parameter data values and on the control data (RETURN_IF_FAIL). A corresponding method is also described.

摘要： A method and system for a handoff in a broadcast communication system is disclosed. A subscriber assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. To streamline the autonomous handoff decision process, several distinct sets of pilot identifiers and rules for transitioning among the sets are defined. To fully integrate broadcast services with the services provided by the cellular telephone systems in a subscriber environment, a methods for various handoff scenarios are analyzed.

摘要： Techniques to adjust the setpoint of a power control loop in a wireless communication system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metrics indicative of the confidence in the decoded results, power surplus/deficit indicative of the difference between the received signal quality and the setpoint and a threshold Eb/Nt needed for the desired level of performance, or a combination thereof. The metrics may include re-encoded symbol error rate, re-encoded power metric, modified Yamamoto metric, minimum or average LLR among decoded bits, number of decoding iterations, and possibly others, The setpoint may be adjusted in different manners and/or by different amounts depending on the above-noted factors. The techniques may be employed for forward and/or reverse links in CDMA systems.

摘要： A method for transmitting data on a reverse link of a wireless communication system comprises transmitting a frame of data on the reverse link via a data channel. The frame is transmitted according to a data rate that is a lower data rate if a current traffic-to-pilot ratio is less than a level corresponding to the lower data rate or is a higher data rate if the current traffic-to-pilot ratio is greater than a level corresponding to the higher data rate. The method further comprises temporarily retaining the data frame in a buffer and monitoring for a message on a forward link indicating a received status of the transmitted data frame. The data frame is processing, retransmitted, discarded or retained based on the received message.
