- Abstract
- An extended paging indicator-based adaptive discontinuous reception method is proposed so as to improve a power saving performance of a terminal in an asynchronous wideband code division multiple access schemes. To this end, a plurality of terminals for performing power saving receive an extended paging indicator for a discontinuous reception cycle, conform a type of a bit Run for configuring the extended paging indicator, and change the discontinuous reception period. In addition, the terminals set the discontinuous reception period update factor value to be varied according to the extended paging indicator as an initial value so as to determine a next paging occasion block, change the discontinuous reception period update factor value according to the paging indicator of the bit Run received from base station, and change the discontinuous reception period according to the variance of the discontinuous reception period update factor value. The extended paging indicator-based adaptive discontinuous reception method may improve transmission time delay and transmission failure probability performances for packet reception as well as a power saving performance in comparison with a conventional fixed discontinuous reception method.
