This is because the user selection for conventional feedback and RVQ feedback cannot avoid large inter-user interference brought by channel quantization.
Furthermore, in [22] the authors consider the problem of optimal user selection for cooperative wireless networks, which do not feature network coding, with the objective of energy minimization.
In particular, BS1 performs exactly the same as SRB to complete the beam and user selection for first cell.
However, it leaves only limited freedom for the actual scheduler, whose task is reduced to user selection for each beam.
Lee et al.[13] consider both scheduling and user selection for CDMA systems, and propose using pricing to select which users are active and to allocate power.
Without loss of generality, we assume that BS1 starts its user selection for beamforming transmission first.
The probabilistic approach we propose offers several additional advantages, including: a) adapting the estimation of blocks to the population, technology, and sample size of the study; b) probabilistic assessment of uncertainty about block boundaries and about whether any two SNPs are in the same block; c) user selection of the probability threshold for assigning SNPs to the same block.
An efficient user selection scheme for the downlink of multiuser MIMO systems is proposed in a multicell environment.
In this article, we have proposed a successive user selection scheme for the downlink of MIMO cellular systems in a multicell environment.
We consider an optimal user selection criterion for the system-wide PF, which can be expressed as ( S opt 1, S opt 2, …, S opt L ) = arg max ( S 1, S 2,.. S L ) U 1, (23).
