Common packet channel

A code-division-multiple-access (CDMA) system consisting of a base station (31, 32, 33) and a service station (35). The base station has a spread spectrum transmitter and a spectral receiver. Serviced stations have a spread spectrum transmitter and a spread spectrum receiver. A message transceiver with a base station transmitter frame sync emits a public synchronization channel. The message spreader common synchronization channel contains a common chip sequence that is common to all service stations. The spread spectrum receiver at the serving station buys the message spreading common synchronization channel, defines the frame synchrony on the frame synchronous signal base, and in response, the server station broadcasts a spread spectrum transmit access burst at low power levels, which contains burst signal power control signals. The receiver in the base station receives the burst signal and detects a service station preamble, in response the spread spectrum transmitter emits an acknowledgment signal. The receiver of the spectrum broadcast at the serving station receives an acknowledgment signal and, in response, emits a first spread spectrum transmitter with a spectral data signal. The transmitter transmits data or power control information to the scattered spectrum receiver on the base station. HE emits a signal containing spectral data. The transmitter transmits data or power control information to the scattered spectrum receiver on the base station. HE emits a signal containing spectral data. The transmitter transmits data or power control information to the scattered spectrum receiver on the base station. HE
