(R_{k}^{text {th}}) accounts for any potential individual rate constraint for user-k.
In comparing competitive equilibrium with Nash equilibrium, the total power allocated to user,, in competitive equilibrium is used as the power constraint for user in Nash equilibrium model to derive a Nash equilibrium.
There are also constraints on the transmit power allocated into each tone, which are referred to as spectral mask constraints, and are characterized by the following set: S = { ( s k n : n ∈ N, k ∈ K ) : 0 ≤ s k n ≤ s k n, mask, n ∈ N, k ∈ K }, (4). in which s k n, mask refers to the spectral mask constraint for user n on tone k.
The main contribution of this article is a method that provides an upper bound to the following OFDMA-SDMA RA problem for mixed RT and nRT traffic: for a given time slot, find the user selection and beamforming vectors that maximize a linear function of the users rates, given a total transmit power constraint and minimum rate constraints for RT users.
Similar to TV's, the car poses constraints for how users can browse and discover content, so the aim is to pare everything down.
On the other hand, the closed system that Apple has adopted presents several constraints – for example, users will initially be unable to import contacts from other services.
The data constraints for both users are active at point t i. (i.e., the set of constraints in Equation 5) c.
This is unfortunate, because we cannot simply ignore the CSIT imperfection in the design of downlink beamformers, for otherwise the resulting solution might violate the SINR constraints for some users.
In this sense, it could be claimed that the role of the lack of demand as a constraint diminished for users because the users perceived that they could gain competitive advantages by following the technological development.
We develop the FNDP formulation as bilevel stochastic mathematical programming with complementarity constraints (STOCH-MPEC) in which the bi-level formulation is converted to a single level using non-linear complementarity constraints conditions for user equilibrium (UE) problem.
