Abstract

A system and method for perceptually optimized image denoising and restoration is provided. The system includes a degradation matrix module that generates a characterized input image from an input image and degradation parameters. A perceptually uniform color space (PUCS) conversion circuit generates an input PUCS image from the input image. A perceptual denoiser circuit generates a denoised PUCS image from the input PUCS image. An inverse PUCS conversion circuit generates an output image from the denoised PUCS image. The input PUCS image may be converted to an angular-frequency image before denoising and back to a pixel-domain image after denoising. A use case profile control circuit may provide conversion parameters to circuits of the system. The input image may be value scaled before denoising and value descaled after denoising. A strength control circuit may provide strength control parameters for value scaling and value rescaling.

Abstract

A system and method for design space exploration where the design space includes a bounded set of dimensions includes anomalous design handling. An intelligent agent is trained to produce optimal design configurations for a design space using feedback provided by an evaluator to a neural network. The feedback is provided by a design evaluator which provides a scalar reward for each of the sample configurations and at least one anomalous design indicator. The scalar reward is calculated based on at least one objective design metric and a weight assigned to the objective metric. The anomalous design indicator identifies that one of the sample configurations in the batch comprises an anomalous design. Policy gradient algorithms in deep reinforcement learning evaluate the rewards in conjunction with an anomalous design reward created from the indicator to update the neural network.

According to embodiments, a UE receives, from a source cell, a mobility pre-configuration radio resource control (RRC) message for random-access channel (RACH)-less access. The mobility pre-configuration RRC message indicates target timing advance (TA) assistance information. The UE receives, from the source cell, a lower layer target access command. The lower layer target access command indicates a most updated or latest network-updated time sensitive dynamic TA assistance information. The UE determines a target cell TA of a target cell based on a latest source cell TA of the source cell, a latest measured timing difference between reference signals (RSs) from the source cell and from the target cell, the most updated or latest network-updated time sensitive dynamic TA assistance information, and the target TA assistance information. The UE performs the RACH-less mobility access to the target cell based on the target cell TA.

Abstract

A video source receives Network Abstraction Layer (NAL) units (NALUs), generates a Real-time Transport Protocol (RTP) aggregation packet comprising the NALUs, ordered in the packet payload in decreasing order of their relative importance to video stream decoding, as determined by the NALU encoder. Once generated, the video source transmits the packet. A network node performs a packet wash on a received RTP aggregation packet that includes a plurality of NALUs. The network node performs the packet wash when the packet size is larger than available space in an outbound queue of the network node. NALUs are successively removed from the payload of the packet, beginning with a last NALU. The packet wash terminates when either the packet will fit in the outbound queue or a maximum number of NALUs have been removed from the packet. If the packet will fit, it is stored in the outbound queue for transmission.

Abstract

A method for performing stateless multicasting in a network implemented by an ingress node of the network. The method includes receiving by the ingress node a first packet from a traffic source. The ingress node determines a point to multipoint (P2MP) path for forwarding the first packet. The ingress node determines a next hop node for each subtree of the P2MP path branching from the ingress node based on a node index forwarding table. The ingress node encapsulates the first packet to generate an encapsulated packet for each subtree. The ingress node encodes a subtree of egress nodes in a multicast routing header (MRH) of the encapsulated packet using a flexible bitstring, an explicit node index, or a combination of the flexible bitstring and the explicit node index. The ingress node sends the encapsulated packet to the next hop node for each subtree.

Abstract

A base station generates a punctured synchronization signal block (SSB) for a channel of a frequency band based on a SSB. A bandwidth of the SSB exceeds a bandwidth of the channel. The punctured SSB includes a punctured physical broadcast channel (PBCH), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS). The PSS of the punctured SSB has a center frequency indicated by a sync raster location of a set of sync raster locations associated with the frequency band. The punctured PBCH is obtained from a PBCH of the first SSB based on a puncture pattern associated with the sync raster location. The base station transmits the punctured SSB in the channel. A user equipment (UE) detects the punctured SSB according to the sync raster location.

Abstract

User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

Abstract

A system and method of parallel processing using input producers and result producers is provided. A unique storage location is assigned to each of the input producers and result producers. Each input producer may have an associated result producer and each result producer may have an associated input producer. Each of the one or more input producers generates input data for the associated result producer, stores the input data in its assigned storage location and signal the associated result producer that the input data is stored. Each of the one or more result producers can then retrieve the input data, generate result data based on the input data, store the result data in the storage location, and signal the associated input producer that the result data is stored. Each associated input and result producer may operate in parallel with other input and result producers.
