摘要： A method and apparatus for decoding a frame of interleaved information bits in a communication system, where the decoding of the frame of interleaved information bits may begin before all of the bits in the frame are received. The frame of interleaved information bits has a frame start time and a frame end time. The frame also includes a first fractional segment that has a start time that is the same as the frame start time and an end time that is before the frame end time. Prior to transmission of the frame of interleaved information bits to a decoding site, all bits in the frame are encoded at a code rate R to provide encoded bits, and the encoded bits are positioned in the interleaved frame in accordance with an interleaving pattern that stores bits having a code rate R1 within a first fractional segment of the interleaved frame.

摘要： A method and apparatus for wireless communications wherein a base station transmits a signal to sending data to a subscriber station through a signal beam that sweeps through the coverage area of the base station. User data addressed to the subscriber station is buffered until the signal beam angle of the signal beam allows efficient transmission. The base station may alter the beam sweep speed or the shape of the beam's radiation pattern over time to maximize system efficiency and capacity.

摘要： In a high data rate communication system, a method and apparatus for selectively reducing the power of signals transmitted by an access terminal. The access terminal generates an access metric based on throughput or data rate control (DRC) information. The access terminal then compares the access metric to an access metric threshold and gates or reduces its transmit power based on the results of the comparison. The access terminal uses algorithms to determine the access metric and access metric threshold that reduce transmit power during periods when the access terminal would not be selected to receive data from an access network according to an access network selection algorithm.

摘要： A method and apparatus for dynamically adjusting the signal-to-interference ratio (SIR) threshold used to control signal transmission power in closed loop communication systems. The closed loop power control comprises an inner loop that provides up/down transmission power control commands to a transmitter based upon a comparison of the SIR for a received signal to the threshold SIR. The outer loop dynamically adjusts the threshold SIR using historic inner loop power control information. When it is detected that the inner loop is not acceptably performing power control, the target SIR is not changed, or may increased or decreased more or less than 0.5 dB or 0.5 dB/99, respectively.

摘要： Forward power control during a soft handoff in a wireless communication system is accomplished by tracking each power command (PC) transmitted from a mobile unit to two or more base station transceiver systems (BTSs). Each BTS may interpret power commands differently due to noise. However, the power commands are relayed to a selector along with additional data transmitted in a conventional fashion. The selector determines the power levels of each BTS and transmits power charge commands to maintain power balance between the BTSs. The BTSs may transmit each PC command to the selector or accumulate several PC commands and send a PC history to the selector. The selector generates a reference PC history, which may be one of the PC histories transmitted from a BTS, a combination thereof, the result of data processing on the one or more PC histories. Individual power change commands or the reference PC history is transmitted back to the BTS to adjust the transmitter output level of each BTS so that the BTSs are transmitting at compatible signal levels.

摘要： In a wireless communication system a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message, is punctured into the high rate packet data transmission.

摘要： Methods and apparatus are presented for dynamically controlling the re-transmission scheme of acknowledgment signals. A source transmits a first data packet over a slot s1. If channel conditions are favorable, source transmits a second data packet over slot s2, which precedes the reception of any acknowledgment signals. A destination receives first data packet over slot d1 and second data packet over slot d2. Destination decodes first data packet during slots d2 and d3, and second data packet over slots d3 and d4. Destination transmits an acknowledgment signal (ACK1) associated with first data packet during slot d4. Rather then transmitting the second ACK1 associated with first data packet over slot d5, destination preempts this slot with an acknowledgment signal ACK2, which is associated with second data packet transmitted by source. Hence, destination is configured to overwrite the repetition of a previous acknowledgment in order to transmit a new acknowledgment.
