Abstract: Techniques and examples of reservation of hybrid automatic repeat request (HARQ) acknowledgment (HARQ-ACK) resources in UCI in wireless communications are described. Accordingly, a UE determines how a HARQ-ACK is to be transmitted to a network node of a wireless network. The UE reserves HARQ-ACK resources among a plurality of resource elements (REs) for a two-bit HARQ-ACK based on a result of the determining. The UE then transmits the HARQ-ACK, having zero bit, one bit or two bits, to the network node in a physical uplink shared channel (PUSCH) using the reserved HARQ-ACK resources such that the PUSCH is punctured for the HARQ-ACK.

Abstract: Embodiments described herein provide a system for facilitating performance enhancement of a storage device. During operation, the system obtains a write request for storing a data page in the storage device. The system then stores the page in a non-volatile accumulation buffer integrated with the storage device and determines whether the accumulation buffer has accumulated at least one block of data. The block of data can indicate a unit of an erasure operation on the storage device. If the accumulation buffer has accumulated the one block of data, the system transfers the block of data to a first block in the storage device from the accumulation buffer.
