Chunk-based resource allocation in OFDMA systems - part I: chunk allocation (2009, methodology): “In a downlink multiuser OFDM system, when subcarriers are mutually independent from user to user, it has been proved in [2] and [4] that the best performance, such as the maximum data rate and the minimum transmit power, can be achieved by allocating single subcarrier to the user with the best chann”
Dynamic association for load balancing and interference avoidance in multi-cell networks (2007, background): “Moreover, equal power allocation is near optimal in many cases especia lly in high SINR regime [15], [16].”
A low complexity algorithm for proportional resource allocation in OFDMA systems (2004, background): “In [6], the rate-adaptive problem was investigated, wherein the objective was to maximize the total data rate over all users subject to power and BER constraints.”
Coordinated Scheduling and Power Allocation in Downlink Multicell OFDMA Networks (2009, methodology): “This method is optimal for the single-cell sum rate optimization where all users have the same weight [40].”
A Coordinated Approach to Channel Estimation in Large-Scale Multiple-Antenna Systems (2012, background): “While diversity-based scheduling methods have been popularized for maximizing various throughput-fairness performance criteria [5], [6], [7], [8], the potential beneﬁt of user-to-pilot assignment in the context of interference-prone channel estimation has received very little attention so far.”
Optimal Resource Allocation for OFDMA Downlink Systems (2006, background): “If all users have equal weights, this is a sum-rate maximization problem where the optimal set selection is to assign each subchannel to the user with the highest channel SNR, and the optimal power allocation is a single level water-filling over this optimal set [ 8 ].”
Joint subcarrier and power allocation in uplink OFDMA systems (2005, methodology): “In real OFDMA systems, the variable, wi,j , has the value of 0 or 1, where wi,j = 1 if subcarrier j is allocated to user i, and wi,j = 0, otherwise (see also [3]).”
Uplink non-orthogonal multiple access for 5G wireless networks (2014, background): “Theoretically, orthogonal transmission is suitable for down-link as it can achieve the maximum users’ sum-rate [4].”
Downlink scheduling and resource allocation for OFDM systems (2009, background): “Sum-rate maximization is considered in [16], [18], [19], where [18], [19] also enforce a minimum bit-rate per user.”
Chunk-Based Resource Allocation in OFDMA Systems—Part II: Joint Chunk, Power and Bit Allocation (2012, methodology): “Although, in traditional resource allocation, the maximization of the average throughput is achieved based on the assumption that the number of bits may take an analog value [6][10], in practice, instead of analog nature, the number of bits per OFDM symbol is of integer nature.”
Downlink Radio Resource Allocation for Multi-Cell OFDMA System (2006, background): “, there is no intra-cell interference [18][19].”
