Optimization and Analysis of Probabilistic Caching in -tier Heterogeneous Networks
Kuikui Li, Chenchen Yang, Zhiyong Chen +1
In this paper, we study the probabilistic caching for an -tier wireless heterogeneous network (HetNet) using stochastic geometry. A general and tractable expression of the succe…
Secure Polar Coding for the Two-Way Wiretap Channel
Mengfan Zheng, Meixia Tao, Wen Chen +1
We consider the problem of polar coding for secure communications over the two-way wiretap channel, where two legitimate users communicate with each other simultaneously while a pa…
ADMM-based Fast Algorithm for Multi-group Multicast Beamforming in Large-Scale Wireless Systems
Erkai Chen, Meixia Tao
Multi-group multicast beamforming in wireless systems with large antenna arrays and massive audience is investigated in this paper. Multicast beamforming design is a well-known non…
Fundamental Storage-Latency Tradeoff in Cache-Aided MIMO Interference Networks
Youlong Cao, Meixia Tao, Fan Xu +1
Caching is an effective technique to improve user perceived experience for content delivery in wireless networks. Wireless caching differs from traditional web caching in that it c…
Polar Coding Strategies for the Interference Channel with Partially-Joint Decoding
Mengfan Zheng, Cong Ling, Wen Chen +1
Existing polar coding schemes for the two-user interference channel follow the original idea of Han and Kobayashi, in which component messages are encoded independently and then ma…
Cooperative Tx/Rx Caching in Interference Channels: A Storage-Latency Tradeoff Study
Fan Xu, Kangqi Liu, Meixia Tao
This paper studies the storage-latency tradeoff in the wireless interference network with caches equipped at all transmitters and receivers. The tradeoff is characterize…
Optimal DoF Region for the Asymmetric Two-Pair MIMO Two-Way Relay Channel
Kangqi Liu, Meixia Tao, Xiaojun Yuan
In this paper, we study the optimal degrees of freedom (DoF) region for the two-pair MIMO two-way relay channel (TWRC) with asymmetric antenna setting, where two pairs of users exc…
Optimal Degrees of Freedom Region for the Asymmetric MIMO Y Channel
Kangqi Liu, Xiaojun Yuan, Meixia Tao
This letter studies the optimal degrees of freedom (DoF) region for the asymmetric three-user MIMO Y channel with antenna configuration , where is the number…
Fundamental Tradeoff between Storage and Latency in Cache-Aided Wireless Interference Networks
Fan Xu, Meixia Tao, Kangqi Liu
This paper studies the fundamental tradeoff between storage and latency in a general wireless interference network with caches equipped at all transmitters and receivers. The trade…
Caching Incentive Design in Wireless D2D Networks: A Stackelberg Game Approach
Zhuoqun Chen, Yangyang Liu, Bo Zhou +1
Caching in wireless device-to-device (D2D) networks can be utilized to offload data traffic during peak times. However, the design of incentive mechanisms is challenging due to the…
