Sentence examples for cellular user to from inspiring English sources
where P D, P C denote the transmit power of D2D users and one cellular user, d iB and d CB represent the distance between the i-th D2D sender and cellular user to the BS, respectively.
Note that when there are more than one cellular users to be served by a base station, the base station just chooses one cellular user to serve at each time slot through the time-division multiple access (TDMA) scheme2.
The interference from D2D users to cellular users can be managed from the power control mechanism; hence, the interference from cellular users to D2D users would be more critical to the D2D operation.
The relays assist D2D pairs and cellular users to speed up their data transmissions with the implementation of network coding.
D2D communications allow proximate cellular users to communicate with each other directly under the control of base station (BS) with lower transmit power requirements.
Such direct D2D transmission enables proximate cellular users to share content directly, which reduces power consumption and improves transmission rates [4].
In order to show the convergence rate of our proposed algorithm, we set the number of cellular users to be 8 and 16 and vary the number of D2D pairs N from 4 20.
Therefore, the strategy of each D2D link d is to occupy the appropriate spectral resource of cellular users to increase the sum rate of its coalition, which is the set of transmission links that shares the same spectrum with d.
As a compromise, we suggest shared access where femtocells choose a time-slot ratio for their home and neighboring cellular users to maximize the network throughput subject to a network-wide QoS requirement.
If (T c −U c )→∞, the coverage probability for a typical cellular user tends to one, that is, begin{array}{*{20}l} {lim}_{(T_{c} - U_{c}) to infty}~mathrm{P}^{c}_{{text{cov}}}(beta_{c}) = 1.
In [8], a single D2D pair is allowed to reuse a single cellular user's resource to maximize the throughput, and also, a closed expression of the optimal power allocation is given.
