Backhaul-Aware Decoupled Uplink and Downlink User Association, Subcarrier Allocation, and Power Control in FiWi HetNets
Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...
متن کاملChannel Aware and Queue Aware Scheduling in LTE Uplink
Long Term Evolution (LTE) uses single carrier frequency division multiple access (SCFDMA) technique as the multiple access scheme in the uplink, due to its low peak to average power ratio (PAPR) compared to orthogonal frequency division multiple access (OFDMA). This advantage is achieved when the Resource Blocks (RBs) allocated to a user are contiguous in frequency domain. Considering this cons...
متن کاملMultiuser OFDM with adaptive subcarrier, bit, and power allocation
Multiuser orthogonal frequency division multiplexing (OFDM) with adaptive multiuser subcarrier allocation and adaptive modulation is considered. Assuming knowledge of the instantaneous channel gains for all users, we propose a multiuser OFDM subcarrier, bit, and power allocation algorithm to minimize the total transmit power. This is done by assigning each user a set of subcarriers and by deter...
متن کاملJoint Subcarrier and Power Allocation for Multiuser OFDM Systems Using Distributed Auction Game
In this paper, we investigate resource allocation issue in a multiuser OFDM cellular network. Each user in the network intends to obtain a higher rate from the BS for its own data transmission (e.g., pictures or videos downloading), but the total transmission resource is limited at the BS. Thus, we formulated this resource allocation problem as an auction game, where the BS acts as the auctione...
متن کاملJoint Subcarrier Matching and Power Allocation for OFDM Multihop System
Relay networks have recently attracted extensive attention due to its potential to increase coverage area and channel capacity. In a relay network, a source node communicates with a destination node with the help of the relay node. The performances of improving the channel capacity and coverage area have been explored and evaluated in the literature (Sendonaris et al., 2003)-(Laneman et al., 20...
