Joint Packet Scheduling and Radio Resource Assignment for WiMAX Networks
The IEEE 802.16 standard defines the QoS signaling framework and various types of service flows, but left the QoS based Packet Scheduling and Radio Resource Assignment undefined. This paper proposes a novel joint Packet Scheduling and Radio Resource Assignment algorithm for WiMAX Networks. Our algorithms can effectively assign the suitable slots to meet the QoS requirements of the different ser...
متن کاملCapacity Enhancement with Joint Subchannel and Power Allocation Scheme for OFDMA Femtocell Networks
Efficient power and subchannel allocation methods are required for orthogonal frequency division multiple access (OFDMA) based femtocell networks to improve the capacity of the system. This paper considers a joint subchannel and power allocation algorithm with capacity maximization for downlink of an OFDMA based femtocell networks. In the proposed algorithm subchannel allocation is first perfor...
متن کاملJoint Subchannel Pairing and Power Control for Cognitive Radio Networks with Amplify-and-Forward Relaying
Dynamic spectrum sharing has drawn intensive attention in cognitive radio networks. The secondary users are allowed to use the available spectrum to transmit data if the interference to the primary users is maintained at a low level. Cooperative transmission for secondary users can reduce the transmission power and thus improve the performance further. We study the joint subchannel pairing and ...
متن کاملJoint Adaptive Modulation and Power Allocation in Cognitive Radio Networks
Link adaptation is an important issue in the design of cognitive radio networks, which aims at making efficient use of system resources. In this paper, we propose and investigate a joint adaptive modulation and power allocation algorithm in cognitive radio networks. Specifically, the modulation scheme and transmit power are adjusted adaptively according to channel conditions, interference limit...
متن کاملJointly power and bandwidth allocation for a heterogeneous satellite network
Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
