Manasa Raghavan

Wireless Systems Engineer.

Patent №:  12206502 – Method and apparatus for group based physical downlink shared channel (PDSCH) hybrid automatic repeat request (HARQ)-acknowledgement (ACK) feedback in wireless communication.

A user equipment (UE) includes a processor configured to: receive a configuration signal from a base station with details of hybrid automatic repeat request process groups (HPGs), each comprising one or more HARQ processes; receive downlink control information (DCI) identifying HPGs for HARQ-ACK feedback; generate a HARQ-ACK feedback signal based on the identified HPGs; and send the feedback signal to the base station.

Ram H Paul, Jr

Principal Research Engineer Medical Devices.

Patent №:  12201321 – Access devices, treatment devices, and kits useful for performing treatment under magnetic resonance imaging and related methods.

Described are MRI-compatible access devices, treatment devices, and kits. An example access device includes an elongate tubular member with a central axis, proximal and distal ends, and a lumen. The tubular member, adjustable between unexpanded and expanded states, features a spiral-shaped opening along its entire length, extending circumferentially around the wall from the proximal to the distal end.

Head of Multimedia Lab at ByteDance.

Patent №:  12206902 – High level control of filtering in video coding.

Techniques for video encoding and decoding include converting a video picture into a bitstream according to a rule. The rule states that the presence of a syntax element for a coding tool at one level depends on a flag indicating whether a syntax structure from a higher level, such as the video picture level or above, is absent at the lower level.

Patent №:  12206859 – Cross-component adapive loop filter. A video processing method involves determining whether to use a cross-component adaptive loop filtering (CC-ALF) tool to refine chroma samples using luma samples during conversion. The refinement includes adjusting chroma values with a final refinement based on an initial filtered luma refinement.

Patent №:  12206850 – Techniques for modifying quantization parameter in transform skip mode. A video processing method involves converting a video block into its coded representation using an identity transform coding tool, ensuring transform domain coefficients match residual block values. A syntax field specifies a quantization parameter, which is adjusted based on a defined rule during decoding.

Patent №:  12206846 – Boundary location for adaptive loop filtering. Techniques for adaptive loop filtering in video processing involve determining luma and chroma ALF boundaries for selective application of filters to respective video components, followed by conversion based on these boundaries.
