“…Consequently, the coverage range of a millimeter wave base station is dramatically limited to only a few hundred meters, even with high-gain (more than 50 dBi at transmitter and receiver combined) antennas used at both the transmitter and receiver. An outage study from the measurement campaign in New York City showed that the maximum cell radius is 200 meters at 28 and 73 GHz, and the major blockage effect is caused by the dense buildings in urban environments [61].…”

“…The second simulation campaign is designed to study and compare the performance of X-TCP against that of other congestion control algorithms after an extended outage event, i.e., after a TCP retransmission timeout is triggered. These events are unlikely in a scenario with a dense deployment of mmWave base stations, because the UE would handover to a different eNB with a very high probability [23], but they may happen nonetheless [24], thus it is important to study the behavior of transport protocols also in these scenarios. In particular, when an RTO is triggered, TCP restarts from slow start with a congestion window set to MSS bytes.…”

Millimeter wave frequencies will likely be part of the fifth generation of mobile networks and of the 3GPP New Radio (NR) standard. MmWave communication indeed provides a very large bandwidth, thus an increased cell throughput, but how to exploit these resources at the higher layers is still an open research question. A very relevant issue is the high variability of the channel, caused by the blockage from obstacles and the human body. This affects the design of congestion control mechanisms at the transport layer, and state-of-the-art TCP schemes such as TCP CUBIC present suboptimal performance. In this paper, we present a cross layer approach for uplink flows that adjusts the congestion window of TCP at the mobile equipment side using an estimation of the available data rate at the mmWave physical layer, based on the actual resource allocation and on the Signal to Interference plus Noise Ratio. We show that this approach reduces the latency, avoiding to fill the buffers in the cellular stack, and has a quicker recovery time after RTO events than several other TCP congestion control algorithms

“…The millimeter-wave band answers some challenges related to the requirements of broadband frequency usage. Millimeter waves still have sufficient bandwidth for the upcoming wireless technology implementation [11], where .28 GHz is one of the frequency candidates for the implementation of 5G network technology [12,13,14].…”

The telecommunication has a tremendous improvement in terms of data rates and bandwidth requiring sufficient frequency allocation and wideband spectrum availability. The millimeter-wave frequency band is one of the solution to these requirements, however communications in this band is facing new challenges on the climate effect to the channel propagation In this paper, we propose a 5G channel model considering the effect of humidity based on the characteristic of the natural environment of Palembang city. The channel model is represented by power levels and delay called a Power Delay Profile (PDP and is derived based on a series of computer simulations using parameters of nature in Palembang. The 5G channel model is important to further derive the outage performance to be used as the theoretical performance of 5G in Palembang since the the Shannon Channel Capacity Theorem is involved in the derivation. We conduct a series of computer simulations to evaluate the validity of the proposed channel model and its characteristics. We found that humidity affect to the performances, where high humidity makes the performances of outage and BER slightly worse, although the effect may be ignored for some applications. The results of this paper are expected to be the references for the development and implementation of 5G Networks especially at the mm-Wave band in Palembang.
