This paper studies the allocation of feedback resources in the downlink of a frequency-division duplex (FDD) multichannel wireless system. We consider a downlink network with a single base station, shared channels, and mobile users. Throughput optimal algorithms like MaxWeight in general require the complete channel-state information (CSI) ( link states) for scheduling. Acquiring the complete...
TDD version of 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) provides a mode of operation in a single block of spectrum with Uplink and Downlink 1ms-subframes multiplexed in time. Limited number of Uplink subframes coupled with unequal number of Physical Random Access Channel (RACH) opportunities per subframe results in TDD LTE RACH resources and the offered load being non-uniform...
In wireless networks, careful planning and link budget analysis is required for delivering maximum throughput reliably with minimum overhead. The efficiency of planning and eventual network performance is totally dependent upon the accuracy and quality of data used for analysis. In most studies, computer simulations and analytical models are used for generating such data. However these simulations...
In wireless networks, the definition of fair resource allocation is ambiguous because the wireless channel condition is not constant over time and location. Two main ways to define fair resource allocation are: by number of allocated service time units per user, temporal fairness, or the number of transmitted bytes per user, throughput fairness. In wireless broadband networks i.e., IEEE 802.16e Mobile...
