Abstract:

This letter explores a device-to-device (D2D) assisted setting in the multi-access networks, where the users communicate with each other and each one can access multiple neighboring cache nodes in a cyclic wrap-around fashion. For such networks, we introduce two new combinatorial arrays namely the caching array and the delivery array to characterize the coded caching process. Based on this, a novel construction of caching array and delivery array is derived through a smart transform over the existing placement delivery array (PDA). The resulting coded caching scheme can achieve a small transmission rate under the case of uncoded placement. It is shown that the proposed scheme has advantages in both the transmission rate and the subpacketization level over the benchmark scheme.
