“…Since the development of next-generation wireless communication networks, massive antenna arrays and mass connectivity are being considered as one of key features, allowing networks to improve its spectral and energy efficiency [3], [4], [5]. This trend is likely to continue in future wireless communication networks, with the number of antenna array elements at the base station (BS) and user connections increasing by an order of magnitude [6].…”

“…Therefore, the Multiple Input and Multiple Output (MIMO) communication technology has been used. This kind of communication system can improve the capacity and spectrum utilization of the communication system exponentially [3]. To analyze the total channel capacity of MIMO system, the spatial channel fading coefficients of all subchannels should be calculated.…”

Multiple-input and multiple-output (MIMO) communication technology which depends on multipath reflection can bring more efficient use of spectrum and higher channel capacity without expanding the bandwidth. This technology has been widely used in 5G communication system these days. However, under some circumstances which are lack of multipath reflection, the performance of traditional MIMO communication is not satisfying. Therefore, some researchers have pointed out that the technology of vortex electromagnetic wave can improve this situation efficiently. This article has done some researches on analyzing the channel capacity in traditional MIMO system and the MIMO system with vortex electromagnetic wave. Firstly, the spatial channel geometry model has been established with a 4-antenna transmit array and a 25-antenna receiving array in a three-dimensional rectangular coordinate system. In order to obtain the total channel capacity, the Los channel fading matrix should be calculated through calculating the distances between each two transmit and receiving antennas. After that the water filling algorithm has been used to decide the power allocation method to each subchannel to get the maximum capacity of the system. Finally, the relationship between maximum channel capacities and the signal-noise ratio (SNR) can be plotted as a line chart. The experiment first compared the capacities with and without the vortex electromagnetic wave of MIMO communication system under different SNR and found that the adding of vortex electromagnetic wave can increase the capacity efficiently. Next the influences of some variables to the channel capacity include the height of transmit antenna array, the distance between each two nearby transmit antenna elements and the variable Q which can change the phase complexity of wavefront have been discussed.

“…Massive MIMO is one of the most important technology in 5G system design [2], such system can significantly improve the channel capacity and energy efficiency. The work in [10] represented that upgrading the BS with Massive MIMO can serve 40 percent more M2M devices in a single cell. Unfortunately, many of the sporadic communication have not considered large-scale antennas at aggregation node.…”

Support massive connectivity is an important requirement in 5G wireless communication system. For massive Machine Type Communication (MTC) scenario, since the network is expected to accommodate a massive number of MTC devices with sparse short message, the multiple access scheme like current LTE uplink would not be suitable. In order to reduce the signaling overhead, we consider an grant-free multiple access system, which requires the receiver facilitate activity detection, channel estimation, and data decoding in "one shot" and without the knowledge of active user's pilots. However, most of the "one shot" communication research haven't considered the massive MIMO scenario. In this work we propose a Multiple Measurement Vector (MMV) model based Massive MIMO and exploit the covariance matrix of the measurements to confirm a high activity detection rate.Index Terms-5G, MTC, grant-free, Massive MIMO.
