Joint Opportunistic Scheduling in Multi-Cellular Systems
We address the problem of multiuser scheduling with partial channel information in a multi-cell environment. The scheduling problem is formulated jointly with the ARQ based channel learning process and the intercell interference mitigating cell breathing protocol. The optimal joint scheduling policy under various system constraints is established. The general problem is posed as a generalized R...
متن کاملOpportunistic Joint Uplink/Downlink Scheduling in WLANs
Recent advances in the speed of multi-rate wireless local area networks (WLANs) and the proliferation of WLAN devices have made rate adaptive, opportunistic scheduling critical for throughput optimization. As WLAN traffic evolves to be more symmetric due to the emerging new applications such as VoWLAN, collaborative download, and peerto-peer file sharing, opportunistic scheduling at the downlin...
متن کاملMeasurement-Based Opportunistic Feedback and Scheduling for Wireless Systems
We study opportunistic feedback of channel state and scheduling of users transmissions at a wireless access point. Our focus is on a regime where users have unknown possibly slowly-varying channel characteristics and it is desirable to limit the resources expended to exchanging channel state opportunistic. The paper argues that opportunistically scheduling the user whose current rate is in the ...
متن کاملA Joint Uplink/Downlink Opportunistic Scheduling Scheme for Infrastructure WLANs
We propose a combined uplink/downlink opportunistic scheduling algorithm for infrastructure WLANs. In the presence of both uplink and downlink flows, an infrastructure WLAN suffers from the uplink/downlink unfairness problem which severely decreases the throughput of the access point (AP). We resolve the unfairness by maintaining a separate queue and a backoff timer for each associated mobile s...
متن کاملJoint source-channel coding with feedback (extended)
This paper quantifies the fundamental limits of variable-length transmission of a general (possibly analog) source over a memoryless channel with noiseless feedback, under a distortion constraint. We consider excess distortion, average distortion and guaranteed distortion (d-semifaithful codes). In contrast to the asymptotic fundamental limit, a general conclusion is that allowing variable-leng...
