The current UL link adaptation algorithm in 5G and 4G was designed for maximization of the UE's spectral efficiency. Such algorithm that requires the UE for maximization of spectral efficiency keeps the MCS high toward a certain target SINR, however without consideration of the UL RB power limitation and utilization. Such implementation causes us to limit the UE's RB allocation, trying to reach the target SINR. Increasing the UL RB utilization is twofold, on the one hand, increase throughput as stated in Shannon's capacity formula, and on the other, increase of our SINR estimation accuracy. Motivated by those reasons, we design a new algorithm which tries to keep the UE to with enough available power to support the user required average RB allocation.

In the case that several transmitting elements (e.g., a Tx chain) are simultaneously impaired, at least two different layouts are possible: the defected Tx chains are randomly scattered around the array; or, the defected Tx chains are aligned vertically on a random column (for 12 and 24 defected Tx chains—1 and 2 such columns are randomly chosen, respectively). It can be seen that the throughput is worse when the defected Tx chains are aligned in a column rather than randomly scattered, unless the defective Tx chains are known, in which case it is the opposite. This is because disabling an entire column has the most significant effect on the spatial null steering. When defected Tx chains are known the performance of all layouts are almost the same, though column yields slightly better results due to the antenna subarrays (2 vertical antennas have the same feed, therefore we lose less degrees of freedom).

A wireless network system is described. In some scenarios MME/MSC/SGSN may act as a client which has huge amount of real-time data to be delivered towards server. For this speedy and reliable delivery requirement, a approach has been proposed which will use multiple parallel HTTP connections for delivery and also make sure that the events related to a particular node is delivered in right order.
