SUMMARY:Scheduling for multi-carrier wireless systems - Lisa Zhang (Bell L

DESCRIPTION:We consider a basestation transmitting data to a set of mobile
  users.\nAt each time step the basestation receives information about the 
 channel conditions to each user. These channel conditions are time-varying
  and user-dependent. The job of the scheduler is to decide which user is s
 erved. In recent years this problem has received a great deal of attention
 .  In the first part of the talk we give an overview of some specific mode
 ls that arise from 3rd generation wireless standards.  We summarize some o
 f the main theoretical results and discuss the performance of scheduling a
 lgorithms that are implemented in practice.\n\nWe also describe some recen
 t work on scheduling wireless data in multi-carrier systems such as 802.16
  (Wimax). Each scheduling decision involves constructing a frame of one or
  more time slots. Within each time slot multiple carriers must be assigned
  to users.  We present a set of results regarding the complexity of the mu
 lti-carrier scheduling problem.\n
