Patent ID: 7706830

Claim:
A wireless code division multiple access (CDMA) subscriber unit comprising: a transmitter configured such that, when the subscriber unit is first accessing a CDMA network and wants to establish communications with a base station associated with the network over a communication channel to be indicated by the base station, the transmitter successively sends transmissions prior to the subscriber unit receiving from the base station an indication that at least one of the successively sent transmissions has been detected by the base station; wherein each of the successively sent transmissions is produced using a sequence of chips, wherein the sequence of chips is not used to increase bandwidth; the transmitter further configured such that the transmitter sends to the base station a message indicating to the base station that the subscriber unit wants to establish the communications with the base station over the communication channel to be indicated by the base station, the message being sent only subsequent to the subscriber unit receiving the indication; wherein at least two of the successively sent transmissions are produced using different sequences of chips; wherein each of the successively sent transmissions is shorter than the message; and wherein each of the successively sent transmissions and the message are produced using portions of a same sequence of chips, wherein the same sequence of chips is not used to increase bandwidth.
