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： A transmitting entity uses different steering vectors for different subbands to achieve steering diversity. Each steering vector defines or forms a beam for an associated subband. Any steering vector may be used for steering diversity. The steering vectors may be defined such that the beams vary in a continuous instead of abrupt manner across the subbands. This may be achieved by applying continuously changing phase shifts across the subbands for each transmit antenna. As an example, the phase shifts may change in a linear manner across the subbands for each transmit antenna, and each antenna may be associated with a different phase slope. The application of linearly changing phase shifts to modulation symbols in the frequency domain may be achieved by either delaying or circularly shifting the corresponding time-domain samples.

摘要： Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

摘要： A method and apparatus for providing diversity transmissions to a mobile unit from a transmitting station having at least first and second antennas by repeatedly switching between the two antennas during the transmission of information to the receiving unit. Message information is transmitted from the first antenna in the transmitting station to the receiving unit. After the start of the transmission of the message information from the first antenna, transmission of the message information from the first antenna to the receiving unit terminates and transmission of the message information from the second antenna in the transmitting station to the receiving unit is initiated. Some time after transmission of the message information from second antenna is initiated, the transmission of the message information from the second antenna to the receiving unit terminates and transmission of the message information from the first antenna in the transmitting station to the receiving unit is initiated. Repeated switching between the first and second antennas is achieved by repeating the process. The switching results in diversity transmissions that improve the ability of a receiving unit to receive the coded and interleaved transmitted message information from the transmitting station. The interleaver disperses the encoded symbols in each antenna dwell period such that the decoder decisions are based on a mix of symbols form each antenna. Therefore the decoder decisions are unreliable only when the mix of symbols from the different antennas, with different fading characteristics, are unreliable over the span of symbols the decoder uses in its decision process.
摘要翻译：一种用于在具有至少第一和第二天线的发射台向移动单元提供分集传输的方法和装置，通过在向接收单元发送信息期间在两个天线之间重复切换。消息信息从发送站中的第一天线发送到接收单元。在从第一天线发送消息信息开始之后，消息信息从第一天线到接收单元的传输终止，并且发送消息信息从发送站中的第二天线到接收单元的发送。开始从第二天线发送消息信息之后的某个时间，消息信息从第二天线到接收单元的传输终止，并且发送消息信息从发送站中的第一天线到接收单元的发送。通过重复该过程来实现第一和第二天线之间的重复切换。切换导致分集传输，其提高接收单元从发射台接收编码和交织的传输消息信息的能力。交织器在每个天线驻留周期中分散编码符号，使得解码器判定基于每个天线的符号混合。因此，只有当解码器在其决策过程中使用的符号范围内，来自具有不同衰落特性的不同天线的符号混合不可靠时，解码器判决才是不可靠的。

摘要： Systems and methods for demodulating and decoding signals on a multi-path data channel using a pilot signal and at least one additional signal as a demodulation reference. One embodiment comprises a method in which a pilot signal is used to demodulate and decode an additional signal, and then both the pilot signal and the additional signal are used to demodulate and decode a data traffic signal. A receiver receives a data traffic signal, a rate indicator signal and a pilot signal. The pilot signal is used as a demodulation reference for the rate indicator signal. After the rate indicator signal is demodulated and decoded, this signal is re-encoded and compared to the received rate indicator signal and used in combination with the pilot signal as a demodulation reference for the demodulation and decoding of the data traffic signal and to estimate SNR for power control purposes.

摘要： A method is taught for improving the transmission of information signals in a communications system having a base station and a remote station. First and second transmission links are established with the remote station. An information signal is encoded to provide an encoded information signal having more bits than the information signal. First and second transmission signals are provided wherein each transmission signal has bits selected from the encoded information signal. Each of the first and second transmission signals is transmitted to the remote station by way of a respective one of the first and second transmission links. The remote station receives and combines the first and second transmission signals transmitted by the remote station to provide a combined encoded signal. The combined encoded signal is decoded by the remote station to provide the information signal. The first and second transmission links can be formed between the remote station and a single base station or between the remote station and two separate base stations.

摘要： Systems and methods for controlling the power level for a mobile station during periods when no data is being transmitted by the mobile station. In one embodiment, data is intermittently transmitted from a mobile station to a base station on a reverse-link traffic channel. When data is being transmitted on the traffic channel, the transmitted data is used by the base station to perform power control operations (e.g., incrementing or decrementing the mobile station's power level, based upon comparison of a received SNR to a target SNR). When no data is being transmitted on the traffic channel, a “zero-rate indicator” is transmitted on the rate indicator channel. The zero-rate indicator is used by the base station to perform power control. Power control based on the zero-rate indicator may use velocity profiles, reliability metrics or other techniques to control adjustment of the power level.
