Abstract: A device for supporting a homomorphic encryption operation includes a ciphertext conversion circuit configured to convert first ciphertexts corresponding to a first operation size to second ciphertexts corresponding to a second operation size, different from the first operation size, to convert the operated ciphertext having the second operation size to a third ciphertexts corresponding to the first operation size, and to perform a homomorphic encryption operation on the second ciphertexts.

Abstract: Apparatuses (including user equipment (UE) and modern chips for UEs), systems, and methods for UE downlink Hybrid Automatic Repeat reQuest (HARQ) buffer memory management are described. In one method, the entire UE DL HARQ buffer memory space is pre-partitioned according to the number and capacities of the UE's active carrier components. In another method, the UE DL HARQ buffer is split between on-chip and off-chip memory so that each partition and sub-partition is allocated between the on-chip and off-chip memories in accordance with an optimum ratio.

Abstract translation: 描述了用于UE下行链路混合自动重传请求（HARQ）缓冲存储器管理的装置（包括用于UE的用户设备（UE）和调制解调器芯片），系统和方法。 在一种方法中，根据UE的活动载波分量的数量和容量对整个UE DL HARQ缓冲存储器空间进行预分区。 在另一种方法中，UE DL HARQ缓冲器在片上和片外存储器之间被分割，使得每个分区和子分区根据最佳比例被分配在片上和片外存储器之间。
