摘要： The present invention is a system and method for increasing user capacity on a slotted random access channel in a spread spectrum communications system by using a multi-part access probe. First and second parts of the access probe are modulated using a short PN code sequence, and the entire access probe is modulated using a long PN code sequence. Information to be transmitted by the access probe is modulated on the second part of the access probe, and the access probe is transmitted so that the first part of the probe falls within the boundaries of an access channel slot. In one embodiment, time slots in access channels used for access signal reception are made the length of the first part. In a further embodiment, time slots in a plurality of adjacent access channels used for access signal reception may be longer than said first part but are offset in time from each other by the length or period of the first part.

摘要： In a time gated frequency division duplexing (FDD) data communication system, the base station transmits two data frames on the forward link to the first remote station and receives two data frames on the reverse link from the second remote station at the first time frame. At the second time frame, the base station transmits two data frames to the second remote station and receives two data frames from the first remote station. Data transmission and reception alternate over consecutive time frames. On the forward link, each data frame is covered with a unique Walsh code. The data is also spread with the short PNI and PNQ codes in accordance with the IS-95A standard. The data can be scrambled by the long PN code. The base station delays the long PN code and short PN codes and properly loads the Walsh codes so that the processed data can be properly demodulated and descrambled by the destination remote station.
