Abstract: The present invention employs training sequence hopping in a cellular communications system to permit tight frequency reuse by minimizing or avoiding co-channel interference and/or other signal degrading phenomena. During a first portion of a transmission, e.g., a first burst, a first training sequence is used. During a second portion of that transmission, e.g., a second burst, a second different training sequence is used. Different training sequences are used for different portions of the transmission according to a predetermined training sequence hopping pattern and with a predetermined number of training sequences. The portion duration can extend for the length of a burst, for more than one burst, for a speech frame, or for some other time period.

Abstract: A method for continuous allocation of real-time (e.g., speech) traffic in a communication system is disclosed, whereby a network allocates, for a timeslot or other medium, a unique radio block for real-time traffic that immediately succeeds a control block (or block otherwise non-allocable for real-time traffic) which is also allocated for that timeslot. The unique radio block is allocated to carry the unit of real-time traffic displaced by the control block, along with the next unit of real-time traffic. The two units of real-time traffic in the allocated radio block are each conveyed in a half-rate mode, while the real-time traffic in a normal radio block is conveyed in a full-rate mode. In this way, the output signals of, for example, a speech codec can be continuously allocated for transmission.
