Time slot hopping of control channel and/or traffic channel in a frequency hopping cellular radio communication system

摘要

A communication system employing MAHO and having a frequency hopping scheme which provides an improved initial synchronization in mobile stations of control channels.
A mobile station, allocated a traffic channel, uses the idle time between active slots for measurements on the control channels of adjacent base stations. Since only a few time slots are available for such measurements, the base stations of conventional communication systems are required to transmit with constant output power on all time slots of the frequency used by the control channel. According to the invention, there are means for using time slot hopping, whereby the time slots used by at least one of said control channel and said traffic channel change from frame to frame.
