Title: RELIABLE UPLINK TRANSMISSION WITHOUT GRANT IN NR URLLC
Abstract:
Systems and methods of enabling grant-free transmission are disclosed. A UE receives a transmission pattern (TP) for a grant-free transmission. The transmission pattern is disposed within a resource pool that contains frequency- and time-domain resource pool configurations. The TP is formed from cell-specific or cell-group specific orthogonal transmission patterns or UE-specific quasi-orthogonal transmission patterns. The frequency is indicated by a bitmap or a start frequency and number of consecutive frequency units. The time configuration is indicated by a bitmap or is indicated by an offset, a number of consecutive frequency units and a period. The frequency- and time-domain resource pool configuration changes periodically.
