LATENCY REDUCTION IN 5G AND 6G NETWORKS

摘要

An apparatus and system for reducing URLLC latency are described. A single packet mode is described in which, when a packet arrives at the PDCP layer for transmission, an indication is sent to a scheduler with the expected size of the packet after ciphering. The packet is then sent to the RLC layer and concurrently submitted to the ciphering engine to enable ciphering to occur in parallel with the other activities. The scheduler determines the expected TB size for transmission of the packet by determining the size of the PDCP, MAC, and RLC headers. The scheduler matches the resource allocation for transmission to the expected TB size.
