“…The resource allocation problem in the multi-cell setting has been studied extensively in the literature [17], [74], [75], [76], [77], [78], [79]. In the following, we consider a simple scenario where both the BS and the remote users are equipped with a single antenna to illustrate the main challenge in multicell power control.…”

Abstract-This paper presents an overview of the theory and currently known techniques for multi-cell MIMO (multiple input multiple output) cooperation in wireless networks. In dense networks where interference emerges as the key capacitylimiting factor, multi-cell cooperation can dramatically improve the system performance. Remarkably, such techniques literally exploit inter-cell interference by allowing the user data to be jointly processed by several interfering base stations, thus mimicking the benefits of a large virtual MIMO array. Multicell MIMO cooperation concepts are examined from different perspectives, including an examination of the fundamental information-theoretic limits, a review of the coding and signal processing algorithmic developments, and, going beyond that, consideration of very practical issues related to scalability and system-level integration. A few promising and quite fundamental research avenues are also suggested.

“…An increased effort is focused on the corresponding time domain radio resource allocation techniques (RRA) [2][3][4] in order to organize the total amount of interference. Additionally, the use of alternate polarization allocation (PA), as a mean to decrease the interference into the desired signal, is introduced in systems operating under LOS conditions [5].…”

SUMMARYThis paper considers the impact of dual polarization adoption on the performance for a fixed wireless access (FWA) network. The major limiting factor of the performance in these systems is co-channel interference (CCI) originating from intracell and intercell concurrent transmissions. The proposed framework combines an appropriate time domain radio resource allocation technique with a dual polarization pattern to mitigate CCI and enhance the obtained signal to interference plus noise ratio (SINR). Simulation results present the performance of the proposed framework against various terrain categories and sector antenna characteristics.

“…Several resource assignment methods have been proposed for the downlink of FWBA systems [2][3][4][5]. In this paper, a radio resource allocation method based on the Enhanced Staggered Resource Allocation (ESRA) method [4] is proposed and analyzed, for the downlink segment of FWBA, leading to an improvement of the throughput per sector for increased traffic load conditions.…”

An improved radio resource allocation scheme with avoidance of major interferers is proposed and analyzed for the downlink of Fixed Broadband Wireless Access (FBWA) systems with full frequency reuse. The scheme is based on Enhanced Staggered Resource Allocation (ESRA) and permits the enhancement of the throughput per sector. Simulation results show a maximum downlink throughput per sector in excess of 44% and an increase of 10% with respect to ESRA is achieved, with Base Station (BS) selection procedure, while meeting a 15 dB signal-to-interference ratio (SIR).
