Which orientation of data allocation can achieve higher probability of data recipient at the mobile station? Whether vertically along frequency domain or horizontally along the time domain?
Hello,
i think the joint use of time and frequency domains could attain the highest scheduling performance.
Indeed, an effective frequency domain scheme could achieve meaningful spectrum efficiency gain.
Frequency domain scheduling, which is based on the exploitation of frequency selectivity, allows to increase the user throughput or to minimize the number of resources need for flow delivery by assigning a given spectrum portion to the user with highest channel gain over such portion. As a consequence, the overall system capacity is also increased.
At the same time, time domain scheduling is essential for QoS provisioning.
For these reasons, I think that the joint use of time and frequency domains is an effective way in order to offer the highest performance for both user and provider sides.
I agree with you for the first part, but for the time domain ! I think QoS satisfaction is also can be achieved through the frequency selective scheduling.
the question in other words: for the moving station (say above 25Km/h) is the vertical allocation of data burst in the form of column along the frequency domain is better or in the horizontal allocation along the time domain. which type can be more suitable for the moving station.
I agree with you, since I also think that frequency domain is more "powerfull"
I think that, in the scenario you are considering with a mobile station, the allocation in the frequency domain is more suitable. Indeed, fast fading can considerably change the quality perceived over the whole spectrum especially when a user is moving and, as a consequence, i think that an adequate frequency scheduling can better exploit the available spectrum resources
