As machine learning requires distributed framework, Federated Learning(FL) is proposed to address the distributed computations in machine learning, especially for privacy protection. In FL, an important problem is to reduce the transmission quantity between the terminals and the centralized server. In this paper the content compression coding for FL is proposed, which can effciently reduce the required transmission bandwidth. The correlation among the parameters of the distributed ANN models is ...

In 5G systems, user mobility research can provide basic support for mobile communications in terms of handover management, resource reservation, etc., improve the robustness of mission-critical services, and reduce total energy consumption and communication delay. In this paper, the association analysis algorithm is used to mine the key movement patterns of users, and the definition of user mobility similarity is proposed. Based on the similar user found by similarity calculation, this paper pro...

WiFi fingerprinting-based localization is limited by heavy site survey in the offline phase, for which fingerprint augment based on gaussian process regression (GPR) is an effective solution. This paper proposes const-linear (CL) and quadratic polynomial (QP) mean function for GPR based on the cognition of signal distribution in indoor positioning scene. The proposed mean function is designed after comprehensively discussing the complexity of the mean function and the fitting accuracy of the rec...

Mobility prediction is an interesting topic attracting many researchers and both prediction theory and models are explored in the existing literature. The entropy metric to evaluate the mobility predictability of individuals gives a theoretical upper bound and lower bound of prediction probability, although the achieved accuracies of users with the same predictability vary. In this work, we investigate the missing locations phenomenon which means the users visit new locations in the testing set....

Multiple access technology is facing a great challenge posed by the upcoming massive Machine-Type Communication (mMTC). Traditional grant-based random access (RA) schemes are not competent to tackle the massive connectivity and small infrequent data packets of mMTC, because of the intolerable signalling overhead and delay. Grant-free random access joint with non-orthogonal multiple access (NOMA) may be suitable for the mMTC services as it reduces the signaling overhead. However, user collisions ...

We propose content compression coding for massive users, where correlated contents of grouped users can be utilized to achieve high compression efficiency. We divide the users into several groups. For each group, we select the group head, encode the information of group head independently, and encode other users referring to the group head. We formulate the grouping optimization problem, transform it to a zero-one discrete optimization problem as well as a subset selection problem, and provide u...

The ultra-dense network (UDN) has been identified as an appealing solution to address the huge service demands in future 5G and beyond. In this paper, we propose an optimization design of UDN balancing user mobility and network densification, where the massive users are divided into different groups according to their moving speeds, and different groups are served by different subnets. This way, the UDN can adjust subnet parameters to meet the service demands using minimum resource. Specifically...

A question that hinges on the wireless communication is the application of big data technology to wireless communication in the physical layer or media access layer. We address the matching-based communication system optimization over parallel channels in wide optical spectrum. It is found that the dimension can be reduced significantly under certain line-of-sight optical wireless communication scenarios. Based on the dimension reduction, we design the quantization points in the reduced dimensio...
