Abstract: A method and system of communication capable of expediting a calibration process which requires a data bus, multiple user nodes connected to the data bus, and data frames for data transmission that each include a data field and/or a control field and a check sum field. One user has a high-precision clock generator, and the remaining users have a clock generator having a lower precision.

Expedited calibration requires the system clock signal period to be set according to a series of measurements and uses any given messages transmitted via the data bus as calibration messages, thus conserving bandwidth on the data bus.

Abstract: A mobile terminal is operated in a cellular communications system that comprises a base station operating in a time division duplex mode. The mobile terminal detects a downlink transmission from the base station and determines therefrom a future moment in time at which an end part of a downlink transmission just prior to a random access window will become detectable at the mobile terminal. An uplink random access transmission is begun at a moment in time that is before the future moment in time. The moment in time that is before the future moment in time can be a fixed amount of time before the future moment in time. If the mobile terminal is not near the edge of the cell, the base station may consequently receive only a partial uplink random access transmission, but this does not detrimentally affect performance.

Variations of the disclosed system include a server in communication with a communications device using a duplex channel. The server includes a scheduler that determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and one or more simplex channels.

A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels.

Abstract: A data transmission technique where high speed data is transmitted differentially in a forward channel by way of a serial link, and relatively low speed data is differentially modulated onto the forward channel signal for transmission in a reverse channel via the link. By utilizing differential modulation in both forward and reverse channels, the resulting signal has a common mode voltage that is substantially constant, resulting in low EM!. The spectral content of the signal associated with the high speed data may be substantially non-overlapping with the spectral content of the signal associated with the low speed data. This facilitates the recovery of the high speed data and low speed data with minimal interference. The differential signaling lends itself for communicating data via an inexpensive medium, such as twisted wire pair or parallel PCB traces. The data transmission technique applies to various communication network topologies: point-to-point, daisy-chain, and point-to-multiple points.

For time synchronization, the terminal performs direct correlation on the received samples with PN2 sequences to detect for TDM pilot 2.
