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 during 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 packet data communication network includes a plurality of base stations for communicating with mobile stations of a user over packet data traffic channels. Radio transmission control nodes control the operation of the plurality of base stations and a scheduler associated with each of the base stations is configured to allocate a first logical control channel associated with a first user application on a first part of an available radio channel resource, and to allocate a second logical control channel associated with at least a second user application on a second part of the available radio channel resource.
