A base station receives access opportunities and packet data over a common packet channel. The common packet channel is defined by a predetermined set of codes and has a plurality of access opportunities. Each access opportunity is defined by a time slot and a signature. A code selection controller selects a currently unused code based on a code associated with a received access opportunity, such that a code, if available, is selected in response to receiving a signature in one of the time slots. The access opportunity defined by the received signature and the one time slot. A transmitter transmits an identifier of the selected available code. The transmitter sends communications encoded with the selected code.

1. A base station comprising:a receiver for receiving access opportunities and packet data over a common packet channel, the common packet channel defined by a predetermined set of codes and having a plurality of access opportunities, each access opportunity defined by a time slot and a signature;a code selection controller associated with the receiver for selecting a currently unassigned code based on a code association with a received access opportunity, such that a code, if available, is selected in response to receiving a signature in one of the time slots, the access opportunity defined by the received signature and the one time slot; anda transmitter associated with the controller which transmits an identifier of the selected available code, whereby the transmitter sends communications encoded with the selected code. 2. The base station of claim 1 further comprising:a sequence generator for producing a replica of a received access opportunity signature;a first mixer for selectively inverting the signature replica in response to the code selection; anda second mixer for selectively mixing the selectively inverted signature with an in-phase or quadrature phase carrier in response to the code selection to produce the identifier. 3.
