Abstract: In a wireless communications system, a base station transmits power control signals (e.g., the power control bits of a power control sub-channel) to a mobile using a forward-link channel that is decoupled from all other signals transmitted from that base station to that mobile. For example, the decoupled forward-link channel may be a common power control channel. The mobile then uses the power control signals received in the decoupled forward-link channel to control its power level for transmitting one or more reverse-link channels to the base station. The ability of base stations to use decoupled forward-link channels in order to transmit their power control signals to a mobile enables a mobile to operate with different active sets for the forward and reverse links. This enables forward-link data traffic to be implemented using a simplex mode, even when the mobile is operating in soft handoff in the reverse link. This in turn greatly reduces the reactivation time involved in transitioning a mobile from the suspended state to the active state, which is particularly desirable for bursty (i.e., intermittent) packet data flow, as opposed to continuous circuit-oriented voice messaging.

Abstract translation: 在无线通信系统中，基站使用从与该基站发送的所有其他信号分离的前向链路信道向功率控制信号（例如，功率控制子信道的功率控制比特）发送功率控制信号 那个手机。 例如，去耦合的前向链路信道可以是公共功率控制信道。 然后，移动台使用在去耦合的前向链路信道中接收的功率控制信号来控制其功率电平，以将一个或多个反向链路信道发送到基站。 基站使用解耦前向链路信道以便将其功率控制信号发送到移动台的能力使得移动台能够利用用于前向链路和反向链路的不同的活动集来操作。 这使得即使当移动台在反向链路中的软切换中操作时，也可以使用单工模式来实现前向链路数据业务。 这又大大减少了将移动台从暂停状态转换到活动状态所涉及的重新启动时间，这对于突发（即间歇性）分组数据流而言是特别需要的，而不是连续的面向电路的语音消息。
