    • 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 includes 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.
    • 用于使用导频信号和至少一个附加信号作为解调参考在多路数据信道上解调和解码信号的系统和方法。 一个实施例包括使用导频信号来解调和解码附加信号的方法,然后使用导频信号和附加信号对数据业务信号进行解调和解码。 接收机接收数据业务信号,速率指示符信号和导频信号。 导频信号用作速率指示信号的解调参考。 在速率指示信号被解调和解码之后,将该信号重新编码并与接收的速率指示符信号进行比较,并与导频信号组合使用,作为数据业务信号的解调和解码的解调参考,并估计SNR 用于电源控制目的。

    • 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.
    • 一种装置,系统和方法通过允许移动台在标准功率电平上发送有效载荷并以提升的功率电平发射较小的有效载荷之间进行选择来有效地管理反向链路资源。 因此,移动台可以自主地选择物理层分组的QoS(服务质量)级别。 基于从基站接收的反向链路传输信息,移动台导出定义用于至少标准服务和升级服务的功率电平和相关联的有效载荷的反向链路传输准则。 移动台从包括至少与标准有效载荷大小相关联的标准反向链路发射功率电平的多个功率电平和与提升的有效载荷大小相关联的提升的反向链路发射功率电平来选择反向链路发射功率电平,其中标准有效载荷 尺寸大于提升的有效载荷大小。
