A wireless communication system has a protocol enabling synchronous code division multiple access (CDMA) communication on a time division duplex (TDD) frequency, and provides for a smart antenna system as an integral component of the system. The protocol has downlink time slots (DTS) which provide for synchronization and paging of all remote terminals from a base station on a omnidirectional code channel and while providing for traffic signals on directional traffic channels. The protocol has uplink time slots (DTS) which enable rapid link requests by remote terminals, as well as enabling improved spacial estimation, synchronization and power control of remote terminals by the base station.

[ We claim:] [11.] In a communication system having a plurality of frames for communication from a plurality of remote terminals to a base station on a common carrier having a plurality of concurrent code channels, each frame of the plurality of frames having a first portion for first synchronization, a second portion for second synchronization, and a third portion for communicating information from the plurality of remote terminals to the base station, a method in a remote terminal comprising the steps of:acquiring a first of the plurality of code channels with the base station by,enabling a transmitter within the remote terminal and transmitting a first synchronization signal during the first portion,disabling the transmitter during the second portion, andenabling the transmitter and transmitting access information including an identification signal unique to the remote terminal in the third portion; andin response to a signal from the base station granting the first code channel, maintaining the first code channel by,disabling the transmitter during the first portion,enabling the transmitter and transmitting a second synchronization signal during the second portion, andenabling the transmitter and transmitting message information during the third portion.
