Abstract: Methods and apparatuses are provided in which position information is determined corresponding to movement of a user equipment (UE) from first local coordinates to second local coordinates. Receive angles of the UE are derived from the position information of the UE. A beamforming weight of the UE is determined based on the derived receive angles of the UE. The beamforming weight is configured such that a beam direction of the second local coordinates matches a beam direction of the first local coordinates.

Abstract: A method may include determining, for a channel, a target component of precoding information, determining at least a part of the precoding information based on the target component and a decompressed component of the precoding information, and sending, from a user equipment, the at least a part of the precoding information. Determining the at least a part of the precoding information may be based on a correlation between the target component and the decompressed component. The at least a part of the precoding information may include a vector of coefficients. The vector of coefficients may include a vector of complex numbers. At least one of the complex numbers may include an amplitude representing a scaling coefficient and a phase representing a rotation coefficient. The target component may include a target matrix. The decompressed component may include a decompressed matrix. The target matrix may include a linear combination coefficients matrix. The precoding information may include a precoding matrix indicator.

Abstract: A method and an apparatus are provided for providing a dolly zoom effect by an electronic device. A first image with a first depth map and a second image with a second depth map are obtained. A first synthesized image and a corresponding first synthesized depth map are generated using the first image and the first depth map respectively. A second synthesized image and a corresponding second synthesized depth map are generated using the second image and the second depth map respectively. A fused image is generated from the first synthesized image and the second synthesized image. A fused depth map is generated from the first synthesized depth map and the second synthesized depth map. A final synthesized image is generated based on processing the fused image and the fused depth map.

Abstract: A method and system include a symbol processing block to generate log likelihood ratios (LLRs) associated with one or more data symbols. The method and system include a channel estimation (CE) module to receive the LLRs from the symbol processing block, and to process iterative CE (ItCE) for new radio (NR) based at least on reference signals and the LLRs. The CE module can process the ItCE with a granularity of one or more resource blocks (RBs) based at least on pilot resource elements (REs) and virtual pilot REs obtained from the LLRs. The CE module can process the ItCE based at least on a frequency domain orthogonal cover codes (FD-OCC) structure of the reference signals. The reference signals can be demodulation reference signals (DMRS) configured in 5G NR. The CE module can process the ItCE by updating a CE result by adding a quantity that represents a contribution obtained from virtual pilot REs.
