Abstract: A method is presented. The method includes organizing a scene as a number of bounding volumes in a hierarchical data structure. The method also includes generating a grid based on the hierarchical data structure. The method further includes mapping each node of the hierarchical data structure to at least one cell of the grid. The method additionally includes identifying a cell of the grid corresponding to an initial intersection location of a ray and the scene. The method still further includes determining a non-root node of the hierarchical data structure as a start node for traversing the hierarchical data structure based on the identified cell. The method also includes traversing the hierarchical data structure starting from the start node to identify a number a primitives intersected by the ray.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive an indication of a first set of parameters that corresponds to a direct communication link between an industrial internet-of-things (IIoT) device and a first controller; receive an indication of a second set of parameters that corresponds to an indirect communication link between the IIoT device and the first controller through a second controller; and schedule a communication on at least one of the direct communication link or the indirect communication link based at least in part on the first set of parameters and the second set of parameters. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for determining a helper UE group to facilitate communications with a target using sidelinks. A helper UE may determine a sidelink channel correlation with at least one other UE, report to a base station channel diversity information, UE state information, UE traffic pattern information, sidelink channel measurements, and the determined sidelink channel correlation; and receive an indication from the gNB if the UE is a member of a helper UE group. A base station may transmit a control message to at least one UE; receive a report comprising sidelink channel correlation information, sidelink channel diversity information, and UE state information, from each of the at least one UE, in response to transmitting the control message; and determine a helper UE group based on the received report.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may transmit a supported configuration of the UE for at least one of SRS transmission or CSI-RS reception for communication with a plurality of TRPs. The apparatus may receive, in response to transmitting the supported configuration, configuration information for at least one of the SRS transmission or the CSI-RS reception, wherein the configuration information is generated based on the supported configuration. The apparatus may communicate, with at least a subset of the plurality of TRPs, using at least one of the SRS transmission or the CSI-RS reception on resource elements assigned based on the configuration information. A base station connected to the TRPs may use the SRS/CSI-RS for cluster management and scheduling or to estimate downlink channels to determine precoding for downlink transmissions.

Abstract: A method for communication by an edge communication device with a network via a relay communication device includes synchronizing to a network using an initial synchronization signal, associating with a relay communication device, entering a power saving state, awakening from the power saving state, searching for a periodic secondary relay synchronization signal (SRSS) transmitted by the relay communication device using an SRSS search window having a duration longer than a duration of a network search window for searching for the initial synchronization signal, synchronizing to the relay communication device based on the SRSS signal, and transmitting data to the relay communication device based on the synchronizing to enable the relay communication device to relay the data to the network.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive an indicator of retransmission scheduling for a plurality of UEs, determine, based on a modulation and coding scheme (MCS) update in the indicator, resources for receiving a retransmission, and receive the retransmission on the determined resources. A base station may receive a negative acknowledgement report from at least one UE of a plurality of UEs, determine a modulation and coding scheme (MCS) update for the at least one UE, generate an indicator of retransmission scheduling for the plurality of UEs, the indicator including the MCS update for the at least one UE, and transmit the indicator.

Abstract: Base stations of neighbor cells can coordinate with each other in allocating grant-free uplink (GUL) resources for a device-to-device (D2D) connection or channel between user equipments (UEs) across the neighbor cells. The base stations coordinate to determine a condition conducive to D2D communication between the UEs. If the condition exists, the base stations coordinate to allocate network resources for D2D communication between the UEs, and establish a D2D connection between the UEs using the allocated network resources for D2D communication.

Abstract: A user equipment (UE) in communication with a base station may utilize multiple code word (MCW) transmissions within a hybrid automatic repeat request (HARQ) process. An original transmission has a first transport block allocated to a first code word and a second transport block allocated to a second code word. Each transport block includes multiple code blocks grouped into code block groups. The UE receives a negative acknowledgement indicating that a subset of the code block groups were not successfully received. The UE retransmits the subset of the code block groups on at least one of the first code word or the second code word in a retransmission in the HARQ process. At least one code block is retransmitted on a different code word in the retransmission than in the original transmission.
