Device and method to allow cross-transmission time interval (TTI) switching and hybrid automatic repeat request (HARQ) operation in a new radio network

摘要

A device of a User Equipment (UE) includes a soft buffer including a plurality of soft buffer partitions to store a plurality of soft bits for a number of hybrid automatic retransmission request (HARQ) processes, wherein the number of HARQ processes includes first HARQ processes corresponding to a first Time Transmission Interval (TTI) Type of a first duration (TTI Type 1), and second HARQ processes corresponding to a second TTI Type of a second duration (TTI Type 2) shorter than the first duration. The device further includes processing circuitry to communicate with a base station in a cellular network, the processing circuitry further to effect a dynamic switching between a TTI Type 1 communication mode and a TTI Type 2 communication mode, and to selectively access the soft buffer partitions to perform, based on the switching, at least one of the first HARQ processes and the second HARQ processes.
