    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive a configuration associated with reporting delta channel state information (CSI). The first wireless communication device may compute the delta CSI based at least in part on the configuration, the delta CSI indicating a difference between first CSI associated with a first connection and second CSI associated with a second connection, the first connection being between the first wireless communication device and a base station and the second connection being between the first wireless communication device and a second wireless communication device. The first wireless communication device may transmit, based at least in part on the configuration, a CSI report including an indication of the delta CSI and at least one of an indication of the first CSI or an indication of the second CSI. Numerous other aspects are described.

    Abstract: Apparatus, methods, and computer-readable media for facilitating techniques for phase continuity of sidelink DMRS bundling are disclosed herein. An example method for wireless communication at a first UE includes receiving a first sidelink transmission including at least a first DMRS. The example method also includes receiving a second sidelink transmission, the first sidelink transmission and the second sidelink transmission together including at least the first DMRS and a second DMRS. The example method also includes receiving, from a second UE, an indication of a bundling relationship between the first sidelink transmission and the second sidelink transmission, the bundling relationship including at least one of strong bundling, weak bundling, or no bundling. The example method also includes performing channel estimation for a channel associated with the first sidelink transmission and the second sidelink transmission based at least in part on the bundling relationship.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a communications device determines at least one position estimation performance parameter, determines a zone identifier based at least in part upon the at least one position estimation performance parameter, wherein the zone identifier identifies one of a plurality of zones, and transmits the zone identifier to one or more UEs. A UE receives the zone identifier, determines the at least one position estimation performance parameter, selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the at least one position estimation performance parameter, and performs the sidelink-assisted position estimation procedure of the UE with at least the selected one or more candidate UEs.

    Abstract: The present disclosure provide various methods, computer-readable media, and apparatuses for managing communication paths, which may include at least one direct communication path between UEs, such as a sidelink communication path. Illustratively, an apparatus of the present disclosure may be a UE or component thereof that is configured to establish a direct wireless communication link and an indirect wireless communication link with another UE to carry data associated with one traffic stream. Further, the apparatus may be configured to communicate with the other UE over at least one of the direct communication link or the indirect communication link after the direct communication link and the indirect communication link are established with the other UE.

    Abstract: Apparatus, methods, and computer program products for relaying and side link communication are provided. An example method may include receiving, from a BS via a controlled discovery procedure, a query to verify a sidelink procedure with at least one UE. The example method may further include establishing, via the BS as a L2 relay, the sidelink procedure with the at least one UE. The example method may further include switching from the sidelink procedure to a sidelink PDCP procedure with a hybrid mode, the BS being an L2 relay for the sidelink PDCP procedure. The example method may further include transmitting to the at least one UE via the BS as the L2 relay, or receiving, from the at least one UE via the BS as an L2 relay, one or more PDCP PDUs corresponding to L2.

    Abstract: Certain aspects of the present disclosure provide techniques for enhanced sidelink (SL) control signaling with time division duplexing (TDD). A method that may be performed by a first user equipment (UE) may include receiving a TDD configuration indicating resources of a resource pool available for SL transmissions between the first UE and at least a second UE and exchanging SL communications with the second UE in one or more slots or symbols based, at least in part, on the TDD configuration. The TDD configuration may define one or more of the slots or symbols as flexible slots or symbols that may be configured as downlink (DL) or uplink (UL) slots or symbols. The TDD configuration may also identify one or more of the slots or symbols as UL slots or symbols and one or more slots or symbols as DL slots or symbols.
