Efficient Scheduling for Heterogeneous Services in OFDMA Downlink
We consider optimal allocation of resources to users in a downlink OFDMA system to support heterogeneous applications consisting of both deadline-sensitive (DS) and best-effort (BE...

Resource and power costs in dynamic spectrum allocation
— We consider a network setting, where a single Service Provider (SP) provides wireless data services to a group of users in the downlink. The transmission model is similar to OF...

Iterative power and subcarrier allocation for maximizing WSMR in cellular OFDMA systems
We consider the resource allocation (RA) problem of maximizing the weighted sum of the minimal user rates (WSMR) of coordinated cells subject to a total power constraint at each ba...

User Profiling: A Method for Limited Feedback in OFDMA Systems
In the OFDMA downlink, obtaining Channel State Information (CSI) from users is necessary for the Base Station (BS) to optimize network performance by intelligently allocating resou...
