Title：6G Satellite-ground Massive MIMO Communication: Key Technologies and Development Prospect

Abstract:  6G will fully supports the space-air-ground integrated network. Satellite-Ground Integrated Communication needs to develop new multi-beam phased array to combat the fading characteristics of satellite communication, improve capacity and rate of transmission. Satellite Multi-antenna System is the trend of the LEO phased antenna. We will discuss the LEO-MIMO Beamforming and MIMO-OTFS which are key technologies of the space-air-ground integrated network. The Antenna Architecture, frequency reusing, capacity performance, propagation characteristics of phased arrays will be discussed as well as the multibeam design and application. And then, the basic multi domain transform is deduced to the disign of the OTFS waveform. We focus on the OTFS Signal Transmission Performance in Satellite-Ground Scenarios, as well as the Satellite MIMO-OTFS Channel Equalization and Detection Technology. A low complexity channel equalization algorithm is designed for the ZP-OTFS system. The simulation results testify the better performance of the Channel Equalization and Detection scheme of the MIMO-OTFS system.

Title：Secure Network Function Computation for Linear Functions: Source Security

Abstract：We put forward (information-theoretically) secure network function computation. In the model, a target function, of which the inputs are generated at multiple source nodes, is required to be computed with zero error at a sink node over a network while being protected from a wiretapper who can access any one but not more than one wiretap set in a given collection of wiretap sets. From the information theoretic point of view, we are interested in characterizing the secure computing capacity, which is defined as the maximum average number of times the target function can be securely computed with zero error for one use of the network. The characterization of this secure capacity with this general setup is overwhelmingly difficult. In this talk, we focus on the secure model for linear functions with the wiretapper being able to eavesdrop any subset of edges in the network up to a certain size, referred to as the security level.

Title：Linear Consensus Algorithm in Wireless Networks

Abstract：In the Internet of Things (IoT), there is the requirement of calculating the average of a set of measurements gathered at nodes without a central node. The linear consensus algorithm is a well-known technique allowing nodes calculate the average locally. In wireless networks, however, the consensus cannot be ensured due to communication errors. Thus, we are concerned with the probability, called convergence probability, that nodes achieve consensus in error-prone environments. Consequently, a lower bound on the convergence probability of the linear consensus algorithm is derived. Besides the expectation used by conventional methods to estimate the convergence probability, the second moment of the consensus measure is taken into account for estimating the lower bound. Then, the Chebyshev inequality is adapted to improve the lower bound of the convergence probability. Next, a new linear consensus algorithm is designed aiming in faster convergence. To this end, each node is requested to complete each iteration by using the last received information even if it is old. It is proved that this method can achieve a higher convergence probability given the number of iterations.

Title：Opportunities and Challenges of Smart Cooperation in Internet of Flying Things

Abstract：Unmanned Aerial Vehicles is a new member of the Internet of Things. Its high dynamic characteristic brings new challenges to the impact of traditional wireless networks. Most UAVs with multi-rotors have very limited resources. Therefore, it is necessary to study how to complete the task effectively and intelligently. In addition, UAVs also need the smart cooperation via Internet. There are many shortcomings of existing research, such as the complexity of trajectory optimization under resource constraints, the difficulty of optimal deployment and energy efficiency optimization of UAVs under large-scale service requests, and the difficulty of multi-dimensional resource collaborative management in dynamic environments. Therefore, it provides enormous opportunities to study key technologies for realizing more intelligent, efficient and reliable services in Internet of Flying Things.
