To enjoy rich Internet services, contemporary mobile devices generate heavy loads of computation tasks, which cannot be suffered locally due to the limited computing and energy capacities of each device. Cloud radio access network (Cloud RNA) based heterogeneous structure is widely accepted as a promising way to make up devices' shortage and computation need. To determine whether the computation task...
Resource allocation in Orthogonal Frequency Division Multiple (OFDM) system is implemented by assigning subcarriers and power to all users in order to achieve large throughput and high energy efficiency. The base station acts as a scheduler, which aims at scheduling active users as many as possible and maximizes the system throughput. Conventional schemes allocate resource to user mainly based on...
In this paper, resource allocation for mixed traffic in wireless access networks is investigated and a utility-based resource dynamic allocation (URDA) algorithm is proposed. This algorithm considers the QoS characteristics, real-time resource requirements and wireless channel states that belong to different types of applications, and then generates utility functions of them. The resource is allocated...
In OFDMA system, inter-cell interference (ICI) and multi-service requirement are challenging problems. Previous cell-level schemes ignored different QoS requirement of multi-service. Meanwhile, most of them only considered complex cell edge part separation but simplified cell inner part allocation to eliminate ICI, but refined inner part allocation could eliminate ICI effectively. To solve this problem,...
