摘要: A wireless packet data communications system that includes a number of modem pool transceivers (MPTs), one or more modem pool controllers (MPCs), and one or more servers. Each MPT receives and processes data packets to generate a modulated signal (e.g., a CDMA spread spectrum signal) suitable for transmission over a terrestrial communications link. Each MPC provides call related processing for one or more MPTs. The servers couple to the MPTs and MPCs via an Internet Protocol (IP) back-bone and provide management of the communications system. The IP back-bone further interconnects the MPTs with one or more data networks and includes a number of routers that route data packets between the data networks and the MPTs. Each MPT can couple to two or more routers for redundancy. Each MPT is operated as an element in an IP network and is associated with an IP address that identifies the MPT. One to three MPTs can be deployed at each cell site to provide wireless data service coverage for up to three sectors at the cell site. The MPCs can either be centralized and coupled to the MPTs via the IP back-bone or distributed about the communications system.

摘要: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

摘要: Methods and apparatus used in a wireless communication system. A data request message may be periodically transmitting by a mobile station to a base station. The data request message may provide information about orthogonal codes to be used by the base station to communicate with the mobile station. The mobile station may receive data transmitted by the base station, the data being transmitted by the base station based on the information about the orthogonal codes provided in the data request message. The information about the orthogonal codes may be based on a quality measure made by the mobile station on a forward link pilot channel from the base station to the mobile station.
