Abstract: Aspects of the disclosure provide methods and apparatuses for video coding. In some examples, an apparatus includes processing circuitry that stores reconstructed samples of a reconstructed block in a memory. When a current sub-block in a current block is to be reconstructed using intra block copy (IBC) based on a reference sub-block in the reconstructed block, the processing circuitry determines whether the reconstructed samples of the reference sub-block stored in the memory are indicated as overwritten based on a position of the current sub-block, generates reconstructed samples of the current sub-block based on the reconstructed samples of the reference sub-block when the reconstructed samples of the reference sub-block stored in the memory are determined to be indicated as not overwritten, and overwrites the reconstructed samples of a collocated sub-block in the reconstructed block stored in the memory with the generated reconstructed samples of the current sub-block.

Abstract: Techniques are disclosed for analyzing a scene depicted in an input stream of video frames captured by a video camera. The techniques include receiving data for an object within the scene and determining whether the object has remained substantially stationary within the scene for at least a threshold period. If the object is determined to have remained stationary for at least the threshold period, a rareness score is calculated for the object to indicate a likelihood of the object being stationary to an observed degree at an observed location. The rareness score may use a learning model to take into account previous stationary and/or non-stationary behavior of objects within the scene. In general, the learning model may be updated based on observed stationary and/or non-stationary behaviors of the objects. If the rareness score meets reporting conditions, the stationary object event may be reported.

Abstract: Techniques are described herein to improve a link budget of physical random access channel (PRACH) transmissions used during a random access (RACH) procedure. The link budget of a PRACH transmission associated with the RACH procedure may be improved by transmitting multiple PRACH transmissions. The multiple PRACH transmissions may be combined to achieve some combining gain. Each retransmission of a PRACH transmission may be done at a higher power level than the previous PRACH transmission. If UE receives an indication that a target base station failed to successfully decode the PRACH transmission, the UE may retransmit the PRACH transmission but at a higher power level than the initial PRACH transmission. PRACH transmissions may be distributed across multiple slots. PRACH transmissions may be distributed across multiple frequency sub-bands in the same slot or across frequency sub-bands in the different slots.
