Abstract:
1. A method for supporting wireless communications between a transmitter and a receiver, the method comprising the steps of: allocating both a first coded channel and a second coded channel in a common direction to support synchronized communications from the transmitter to the receiver; assigning a time segment in which the transmitter communicates an indication to the receiver by generating a reference signal over a selected one of the first coded channel or the second coded channel; maintaining transmissions on the first coded channel and the second coded channel in a time segment by analyzing the reference signal on the first coded channel or the second coded channel at the receiver; and adjusting timing of the transmitter by sending a message from the receiver to the transmitter indicating whether to advance or retard timing so that subsequently generated reference signals on the first coded channel or the second coded channel fall within a corresponding time segment, wherein the message indicating whether to advance or retard timing at the transmitter includes a single bit indicating whether to advance or retard timing, the timing is advanced or retarded a predefined time depending on a logic level of the single bit and the timing is advanced or retarded based on a second predefined time if the single bit is in a same state for a predetermined number of periods in a row, the second predefined time being greater than the first predefined time.
