Abstract: A method and apparatus to construct a bounding volume hierarchy (BVH) tree includes: generating 2-dimensional (2D) tiles including primitives; converting the 2D tiles into 3-dimensional (3D) tiles; and constructing the BVH tree based on the 3D tiles.

Abstract: A method for communication by a base station in a wireless network is provided. The method includes establishing a radio resource control (RRC) connection with a user equipment (UE) in the wireless network, receiving at least one report including information indicating channel condition of at least one radio channel, from the UE, and configuring additional demodulation reference signal (DMRS) based on the information indicating the channel condition of the at least one radio channel, using a media access control (MAC) control element (MAC-CE).

Abstract: A method of optimizing uplink signal detection threshold is provided. The method includes initializing a current detection threshold in an allowable range of uplink detection thresholds for detection of a plurality of uplink signals for a predetermined time period and selecting and applying a detection threshold within a narrow window centered around the current detection threshold at the physical (PHY) layer. The method further includes determining whether a corresponding uplink signal among the plurality of uplink signals is detected correctly or falsely at a medium access control (MAC) layer and accumulating, for the applied detection threshold, the corresponding results of the determination at the MAC layer. The method further includes determining an optimal detection threshold from the narrow window based on an analysis of the accumulated results and applying the determined optimal detection threshold at the PHY layer as the current detection threshold for the detection of the plurality of uplink signals.
