Problems solved by technology

The latter can be seen as an inefficient utilization of the frequency band and also leads to an unnecessary increase in channel contention
[0011] Second, even if the UE successfully sends HARQ feedback, the gNB may fail to detect this HARQ feedback
From the gNB point of view, failed LBT or lost UCI transmissions are indistinguishable

Abstract

A wireless device receives downlink control information (DCI) from a network node, determines a physical downlink shared channel (PDSCH) group based on information in the received DCI, transmits a hybrid automatic hybrid automatic repeat request acknowledgement (HARQ-ACK) report to the network node based on the determined PDSCH group, and receives radio resource control (RRC) configuration information, wherein determining the PDSCH group comprises identifying a PDSCH group index within the DCI based on the received RRC configuration information, the RRC configuration information comprises an indication of whether PDSCH grouping functionality is enabled with respect to the wireless device.

Description

technical field [0001] The disclosed subject matter relates generally to telecommunications. More specifically, certain embodiments relate to concepts such as: wireless communication in unlicensed spectrum, 5G New Radio (NR), unlicensed NR (NR-U), hybrid automatic repeat request acknowledgment (HARQ-ACK) reporting, and Physical Downlink Shared Channel (PDSCH) grouping. Background technique [0002] The above information disclosed in this "Background" section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in the art to a person of ordinary skill in the art. [0003] NR provides flexibility in HARQ feedback timing to account for dynamic time division duplexing (TDD), and possibly combine multiple HARQ feedbacks to achieve both low overhead and high reliability. [0004] figure 1 An example of HARQ feedback for dynamic TDD is shown, where data transmis...
