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： 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： An apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload at a standard power level and transmitting a smaller payload at a boosted power level. The mobile station, therefore, can autonomously select a QoS (Quality of Service) level for physical layer packets. Based on reverse link transmission information received from a base station, the mobile station derives a reverse link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse link transmission power level from a plurality of power levels including at least a standard reverse link transmission power level associated with a standard payload size and a boosted reverse link transmission power level associated with a boosted payload size where the standard payload size is greater than the boosted payload size.

摘要： A base station (BS) (110) in a wireless network (100) establishes power levels for transmitting messages acknowledging receipt of packet data from a mobile communications device (MCD) (114). In one implementation, the BS infers whether the MCD received a given acknowledgement message by considering whether (306, 316) the next communication from the MCD comprises new packet data, and whether (310, 320) that data comprises re-transmitted data. The BS adjusts (312, 314, 322, 324) transmit power level for future acknowledgement messages according to whether the MCD received past acknowledgement messages. In a different implementation, actual/estimated transmit power from a serving base station to a given MCD is averaged (404), and increased (406) by a prescribed amount to yield a target level. Whenever the non-serving base station transmits messages acknowledging receipt of packet data from the MCD, the non-serving base station transmits (408) at the target level.

摘要： A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.
摘要翻译：使用动态共享前向链路信道（或“数据”信道）将组播数据发送到一组无线设备，例如使用用于数据信道的公共长码掩码。参考功率控制（PC）位也在数据通道上发送并用于信号质量估计。共享的前向链路控制信道用于向各个无线设备发送用户特定的信令，例如对于每个无线设备使用时分多路复用（TDM）和唯一的长码掩码。共享的前向链路指示符信道用于向无线设备发送反向链路（RL）PC比特，例如使用TDM。数据通道由接收数据通道的所有无线设备共同供电控制。控制和指示器通道由每个无线设备单独进行功率控制，使得在这些信道上为无线设备发送的信令和RL PC位被可靠地接收。
