ABSTRACT:
To address the need to provide power control for listening participants of CDMA dispatch services, the concept of “shared channel signaling windows” for shared traffic channels (e.g.,110) is described. In one embodiment, the beginning of a signaling window is announced on the traffic channel and the remote units (e.g., MS120) with the highest frame error rates compute the shortest transmit delays. For the duration of the window, remote units transmit their power control signaling according to their transmit delays. Thus, listening participants are given an opportunity, according to need, to perform power control signaling on the group traffic channel.
