Abstract:
A cellular communications system comprising at least one base station site synchronized system part, including a packet switched mode, wherein packet control channels are allocated on physical channels, consisting of a combination of frequency and at least one time slot, and wherein said physical channels carrying packet control signalling are arranged in a reuse pattern, such that both frequency and timeslot are utilized in said reuse pattern, comprising;means for allocating, in a first base station site, said control channel signalling to a certain set of physical channels on at least one frequency and a certain time group, defined by at least one timeslot, means for allocating, in a second base station site, said control channel signalling to a certain set of physical channels on said at least one frequency and a certain time group, defined by at least one timeslot, wherein said time group used in said second base station site is defined to be non-simultaneous in transmission to said time group used in said first base station site, means for preventing, in said second base station site, the allocation of user data channels on physical channels that substantially coincide in time and frequency with physical channels allocated for control channel signalling in said first base station site.
