Abstract [en]

The  radio  resource  management  (RRM)  techniques  used  in  current  2nd  generation  mobile communication systems rely heavily on fixed frequency or timeslot allocation  techniques  which  are  not  well  suited  for  large  variations  in  data  rates.  Spread  spectrum  systems  proposed  provide  partial  solutions  to  this  problem  but  exhibit  deficiencies  when  faced  with  uneven  user  populations.  The  overall  objective  of  ACTS  project  AC090  FRAMES  is  to  define,  develop  and  evaluate  a  wideband  multiple radio access scheme fulfilling  the UMTS requirements. Within  the project  several RRM concepts have been proposed. The "bunch" concept discussed  in  this  paper uses synchronous dynamic physical layer radio resource reservation combined  with fast SIR based power control in a local cluster ("bunch").  Uncontrolled, "inter­  bunch",  interference  is  handled  by  time/frequency  hopping  ("interference  averaging"). In the paper some initial performance results are presented.
