Title:
IMPROVED ADJUSTMENT VALUE FOR INBOUND TIME-SLOTTED TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO2004095721
Kind Code:
A3
Abstract:
A subscriber (1001) provides a cumulative adjustment value in memory. Upon transmission of the inbound signal to a base station (102), the subscriber (1001) receives a relative adjustment value. The base station (102) calculates the relative adjustment value based on receipt of the inbound signal against a time window. The subscriber (1001) sums the adjustment value with the cumulative adjustment value to create a new cumulative adjustment value. The subscriber (1001) stores the new cumulative adjustment value in memory, and a subsequent inbound signal is transmitted using the new cumulative adjustment value. Alternatively, the subscriber (1001) obtains a priori information as to when a base station (102) transmits a burst. Upon receipt of the burst, the subscriber (1001) calculates a time delay between when the burst was transmitted and when the burst was received. The subscriber (1001) stores the time delay, and advances the transmission timing by the time delay.
