Abstract: Methods, systems, and devices for sidelink groupcast communications are described. A user equipment (UE) may transmit a beam training request to a base station to determine beams for use with other UEs in a sidelink groupcast communications group. The base station may receive the beam training request, identify wireless resources that a group of UEs may use to perform beam training, and may transmit a beam training grant to each UE of the group of UEs. The UE may transmit a number of training beams using the wireless resources provided in the beam training grant, and the other UEs may measure received signals on the wireless resources to identify one or more beams. Each UE may provide a beam training report to the base station. The base station, based on the beam training reports, may determine beams and resources for use in the groupcast sidelink communications.

Abstract: A shared-nothing database system is provided in which parallelism and workload balancing are increased by assigning the rows of each table to “slices”, and storing multiple copies (“duplicas”) of each slice across the persistent storage of multiple nodes of the shared-nothing database system. When the data for a table is distributed among the nodes of a shared-nothing system in this manner, requests to read data from a particular row of the table may be handled by any node that stores a duplica of the slice to which the row is assigned. For each slice, a single duplica of the slice is designated as the “primary duplica”. All DML operations (e.g. inserts, deletes, updates, etc.) that target a particular row of the table are performed by the node that has the primary duplica of the slice to which the particular row is assigned. The changes made by the DML operations are then propagated from the primary duplica to the other duplicas (“secondary duplicas”) of the same slice.

Abstract: In one aspect of the disclosure, a UE may be configured to receive, from a base station, information indicating a reference point associated with at least one L1 measurement; determine a reporting value of the at least one L1 measurement based on a difference between the reference point and a measured value of the at least one L1 measurement; and transmit information indicating the reporting value to the base station. In another aspect, a RAN node can indicate to a UE that a reduced measurement report resolution is to be used for beam measurements in a measurement report. The reduced measurement report resolution is less than a first measurement report resolution previously indicated to be used for the beam measurements. Lower resolution can be obtained by using fewer bits to indicate one or more of the beam measurements. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the UE transmits the measurement report to the RAN node.

Abstract: Methods, systems, and devices for wireless communication are described related to timer-based sidelink discontinuous reception (DRX). A UE may receive configuration information for a sidelink DRX mode from a base station or another UE, which may indicate one or more parameters of the sidelink DRX mode. When operating in the sidelink DRX mode, a group of UEs may have shared active durations and inactive durations for coordinating sidelink communications. In a timer-based sidelink DRX mode, if a UE receives or transmits a sidelink communication, the UE may initiate an inactivity timer, and the UE may continue to monitor a sidelink channel for other sidelink communications while the timer is running. One or more rules may govern the operation of an inactivity timer with respect to the shared inactive durations.
