Abstract: This disclosure provides techniques for reducing waste of user equipment (UE) resources caused in transmission of a Physical Uplink Shared Channel (PUSCH) when a UE conducts searching for downlink control information (DCI) outside of a PUSCH transmission. This disclosure defines a first search space on the basis of an existing second search space that was used to receive DCI information to schedule a PUSCH. The first search space can be used to obtain a DCI having an ACK feedback. This disclosure provides systems and methods for determining the location of the first search space to receive a second DCI having ACK feedback during a PUSCH repetitive transmission and whether the second search space should be used for the second DCI instead. Outside of the PUSCH transmission, the UE receives DCI in the second search space, decreasing the unnecessary searching of DCI and increasing network efficiency.

Abstract: Techniques for synthesizing and analyzing data are disclosed. A ML model anonymizes microdata to generate synthesized data. This anonymizing is performed by reproducing attributes identified within microdata and by applying constraints to prevent rare attribute combinations from being reproduced in the synthesized data. User input selects attributes to filter the synthesized data, thereby generating a subset of records. A UI displays a synthesized aggregate count representing how many records are in the subset. Pre-computed aggregate counts are accessed to indicate how many records in the microdata embody certain attributes. Based on the user input, there is an attempt to identify a particular count from the pre-computed aggregate counts. This count reflects how many records of the microdata would remain if the selected attributes were used to filter the microdata. That count is displayed along with the synthesized aggregate count. The two counts are juxtaposed next to one another.
