Abstract: A point cloud attribute encoding method and apparatus, decoding method and apparatus are disclosed. The point cloud attribute encoding method includes: sorting point cloud data to be encoded to obtain sorted point cloud data; constructing a multilayer structure based on the sorted point cloud data and distances between the sorted point cloud data; obtaining an encoding mode corresponding to each of nodes in the multilayer structure. The encoding mode corresponding to each of the nodes is a direct encoding mode, a predictive encoding mode, or a transform encoding mode. The predictive encoding mode is to encode a node based on information of a neighboring node corresponding to the node. The transform encoding mode is to encode the node based on a transform matrix; and encoding point cloud attributes for each of the nodes based on the multilayer structure and the respective encoding mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect a radio link failure between the UE and a master node of a dual-connectivity configuration. The UE may transmit, to a secondary node in the dual-connectivity configuration, an indication that the radio link failure has occurred. The secondary node may receive the indication of a radio link failure and transmit the indication of the radio link failure to the master node of the dual-connectivity configuration. The master node may identify a target node for the UE and perform a handover procedure of the UE from the master node to the target node.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) measure and report cell measurements for neighboring cells to assist the wireless network with handover decisions. In some cases, the UE may be configured to report beam-level measurements for just a subset of neighboring cells instead of each neighboring cell. For example, the UE may measure, or report beam measurements for a subset of the neighboring cells which meet configured criteria or are included in a subset of cells configured by the serving cell. Techniques for configuring and maintaining the subset of cells are described herein. For example, the cells in the subset may be configured by the UE or the serving cell of UE. A cell may also be removed from the subset if the cell does not continue to meet criteria for being included in the subset.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.
