CONFIGURED GRANT RESOURCE CONFIGURATION FOR NEW RADIO-UNLICENSED - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18342383 Titled 'CONFIGURED GRANT RESOURCE CONFIGURATION FOR NEW RADIO-UNLICENSED'
Simplified Explanation
The abstract describes the configurations for a new radio unlicensed (NR-U) system called Configured Grant (CG). CG configurations can be provided using a bitmap or a resource indicator value (RIV) signaling of start/end symbols. These configurations allocate time division resources and can include common start/end symbols for contiguous allocations. The CG configuration allows for mini-slots within already configured CG slots. There are two types of repetition configurations for coverage and faster retransmission. Multiple user equipment (UE) can be identified in the uplink control information (UCI) and UEs can increase power in the absence of downlink feedback information (DFI).
Original Abstract Submitted
Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DFI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DFI.
