Abstract
A method for selectively modulating data in a mobile station, includes checking whether a power control bit is included in the received data, demodulating the received data including the power control bit, if the power control bit is included, and turning off the receiving power when demodulation is completed. The demodulating step includes demodulating an initially repeated data frame group at only one location in the data frame and demodulating data frame groups containing power control bits. The receiving power is then turned off without demodulating remaining groups in the data frame, which include groups which do not contain a power control bit.

13. A method for selectively demodulating data in a mobile station, comprising:
-
checking whether a data rate of data received from a base station corresponds to a predetermined value;
if the data rate does correspond to the predetermined value, then (a) searching a data frame in the received data to locate a first set of groups which repeats in the data frame;
(b) demodulating the first set of groups in the data frame;
(c) checking whether a power control bit is included in at least one other group in the data frame when demodulation is completed;
(d) demodulating said at least one other graph in the data frame which includes the power control bit, if the power control bit is included; and
not demodulating(e) turning off receiving power of the mobile station when demodulation is completed.

24. A method for selectively demodulating data in a communications system, comprising:
-
receiving a data frame having a plurality of groups; and
demodulating only a portion of the groups in the data frame, said demodulating step being performed based on a data rate of the data frame.
