The first solution to the optimal frequency allocation is a centralized solution that can handle the more general form of constraints as compared with prior research. The second solution is a distributed version for large networks using a pricing scheme. It is capable of incremental adjustment when...

In this paper, we propose an optimization framework of offloading from a single mobile device (MD) to multiple edge devices. We aim to minimize both total tasks' execution latency and the MD's energy consumption by jointly optimizing the task allocation decision and the MD's central process un...

In other words, when an MS with multi-carrier capability is provided an allocation, it includes the last ith mini-band LRU in partition FP0 together with the ith guard mini-band LRU. When an adjacent component carrier is not an active carrier for the MS, the guard sub-carriers between ...
operate on specific frequency bands. the allocation of frequencies ensures efficient communication, preventing interference between various devices. understanding the role of frequency is vital for optimizing signal strength, minimizing disruptions, and enhancing overall wireless connectivity in diverse environment...
摘要: In this paper, we study the performance of frequency allocation schemes in forthcoming OFDMA-based systems. These systems include WiMAX and 3G long term evolution. We first develop an analytical model for the collisions for an arbitrary number of users in...
One unit of channel resource allocation is referred to as a block. After doing so, a coded data frame is then put into a resource matrix after being partitioned into S segments such that S≤T. One frame segment utilises a resource block. In the context of operationally plausible ...
After DTV transition, frequency allocation to efficiently utilize 700 MHz band, which is remained as Digital Dividend, is in progress domestically and internationally. This paper investigates global frequency allocation of 700 MHz band a... DK Park 被引量: 0发表: 2014年 Digital Technologies and Ne...
These communications may be part of a multicast service, in which a selected group of UEs are able to receive the same data, or a broadcast service, in which all UEs are able to receive the same data. Further study on enhancing resource allocation to facilitate these multicast and broadcast...
