Slot aggregation

Abstract

In a downlink transmission from a base station to user equipment, multiple mini-slots are defined, each comprising one or more OFDM symbols. Data for transmission is then mapped to an aggregation of these mini-slots and transmitted to the UE with an indication of the scheduling. The aggregated mini-slots may be contiguous or non-contiguous in time, and likewise in frequency. Each mini-slot may comprise a DMRS in its first symbol, and the aggregation may be defined according to the desired repetition rate for the DMRS. The aggregated mini-slots may all be located in the same slot or over multiple slots. The indication of scheduling may be transmitted in DCI in the PDCCH of the slot in which the first mini-slot occurs, and may include the number of mini-slots in the aggregation and the aggregation pattern. The mini-slots may be used to transmit URLLC data by pre-empting previously scheduled transmissions. Aggregation may reduce control overheads as one DCI can schedule multiple mini-slots.
