Optimal Downlink Resource Allocation in OFDMA Distributed Radio Access Network

Throughput-optimal resource allocation in LTE-Advanced with distributed antennas

“…In the latter, instead, a linear optimization problem is proposed to match multiple RUs to UEs, hence assuming spatial multiplexing. However, the objectives and the models of [4] and [23] differ from ours. Neither take finite buffers into considerations, and [4] constrains a UE to receive transmissions from one antenna only.…”

“…The problem of MAC-level resource allocation on LTE-A with DAS is relatively new, which justifies the paucity of the literature on the subject. The works that are most directly related to ours are [4] and [23]. In the former, authors deal with the problem of allocating transmission power and logical subbands to downlink transmissions.…”
