Abstract: A method for synchronizing timing of signal transmissions in a telecommunication system (100) determines a "fixed portion" (222) of the propagation delay between the central unit (102) and subscribers (206, 208) in a particular node (202). Additionally, the method determines a `variable portion` (226) of the propagation delay that accounts for the variation of spacing of different subscribers (e.g., homes (206, 208)) on a particular node (202). The preferred method offsets the control unit's (102) receiving window (410) in accordance with the fixed portion, and directs the various subscriber units (206, 208) to offset the timing of signals (314, 322) (i.e., bursts of data) that they transmit by the variable portion (226).

Abstract: A method and apparatus for controlling data transmissions from a first communications unit (202) to a second communications unit (210). Data transmissions received from the first communications unit (202) at the second communications unit (210) are processed to determine a power level of the data transmission. In response to a determination that the power level is not within a desired range or operating window (400), an adjustment value indicating the amount of change needed in the power level of the data transmission from the first communications unit (202) to fall within the desired range or operating window (400) is determined. This adjustment value is sent to the first communications unit (202). In response to receiving an adjustment value from the second communications unit (210), the first communications unit (202) adjusts the power level of its data transmissions.
