    Abstract: Disclosed is a method of integrating voice and data services onto a same frequency channel using available transmit power information to determine data rates, wherein the available transmit power information indicates an amount of transmit power available for future data transmissions over one or more data channels. In a "distributed" embodiment, a transmitter or base station transmits, via a forward link, an available power message to a receiver or mobile-telephone indicating an amount of available transmit power at some future time t+z . The mobile-telephone performs signal-to-interference measurements corresponding to the received forward link and received interference, and uses such signal-to-interference measurements and the available power message to determine a data rate that can be supported by the mobile-telephone. Preferably, the determined data rate corresponds to a maximum data rate at which a minimum level of quality of service can be achieved at the mobile-telephone. In a "centralized" embodiment, the mobile-telephone transmits the signal-to-interference measurements to the base station, and the base station determines the data rate based on the available transmit power at future time t+z .

    Abstract translation: 公开了一种使用可用的发射功率信息将语音和数据业务集成到相同频率信道上以确定数据速率的方法，其中可用发射功率信息指示可用于将来数据传输在一个或多个数据信道上的发射功率量。 在“分布式”实施例中，发射机或基站经由前向链路将可用的功率消息发射到接收机或移动电话，指示在某个未来时间t + z的可用发射功率的量。 移动电话执行对应于所接收的前向链路和接收到的干扰的信号到干扰测量，并且使用这样的信号对干扰测量和可用功率消息来确定移动电话可以支持的数据速率。 优选地，确定的数据速率对应于在移动电话处可以实现最低服务质量水平的最大数据速率。 在“集中”实施例中，移动电话将信号到干扰测量发送到基站，并且基站在未来时间t + z基于可用发射功率来确定数据速率。
