Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: A dual-polarized multiple-input-multiple-output (MIMO) mobile device is provided that includes a first array of antennas and a second array of antennas. Based upon a blockage of at least one of the array of antennas being less than a blockage threshold, the mobile device operates in a default configuration in which a default polarization selection from the second array is used in combination with a fixed polarization selection from the first array to form a first MIMO layer signal and a second MIMO layer signal. Should the blockage exceed the blockage threshold and an optional performance threshold be satisfied, the mobile device may operate in a dynamic configuration in which a dynamic polarization selection from the second array is reversed as compared to the default polarization selection.

Abstract: In an aspect, a user equipment (UE) may receive positioning assistance data from a location server, wherein the positioning assistance data identifies one or more first positioning reference signal (PRS) resources for measurement by the UE during a positioning session between the UE and a location server. The UE may receive post-measurement positioning assistance data from at least one sidelink device located within a threshold distance to the UE, wherein the post-measurement positioning assistance data received from the at least one sidelink device is based on measurements of one or more second PRS resources obtained by the at least one sidelink device during a positioning session of the at least one sidelink device. The UE may selectively measure at least a subset of the one or more first PRS resources based on the post-measurement positioning assistance data received from the at least one sidelink device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication, including sidelink beam management responses. In some aspects, a first user equipment (UE) may receive, in one or more mini-slots, one or more sidelink signals of a plurality of sidelink signals (e.g., sidelink reference signal blocks (S-RSBs), sidelink beams, sidelink reference signals, etc.) for sidelink beam management associated with a second UE; and transmit, to the second UE, at least one response associated with at least one sidelink signal of the one or more sidelink signals received. In some aspects, a first UE may transmit, in a plurality of mini-slots, a plurality of sidelink signals; and receive, from one or more other UEs during one or more response occasions associated with the plurality of sidelink signals, one or more responses associated with at least one of the plurality of sidelink signals. Numerous other aspects are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive transmission configuration indicator (TCI) activation information associated with identifying a set of carriers, wherein the set of carriers maps to a set of transmit receive point (TRP) mode values. The UE may communicate on a carrier, of the set of carriers, using a TCI state of the carrier, of one or more maintained TCI states of the carrier, and a communication configuration associated with a TRP mode of the carrier, the TRP mode being based at least in part on a TRP mode value, of the set of TRP mode values. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A reconfigurable reflective surface (RIS) may receive control information from a network entity. The control information may be usable at the RIS for determination of a set of phase parameters. The RIS may determine whether distance information between the network entity and the RIS is available. The RIS may determine the set of phase parameters in accordance with the control information. The set of phase parameters may be usable by the RIS for reflecting communications from the network entity to a user equipment (UE) in accordance with a focusing distance that may be based on the determined availability of the distance information. The RIS may apply the set of phase parameters to reflect a signal from the network entity to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reconfigurable intelligent surface (RIS) may select a weight vector, from a plurality of stored weight vectors, for enabling a spatially multiplexed communication, between a transmitter and a receiver, that includes two or more layers for each polarization of a plurality of polarizations for the spatially multiplexed communication. The RIS may receive the spatially multiplexed communication from the transmitter. The RIS may transmit the spatially multiplexed communication to the receiver in accordance with the weight vector.

Abstract: Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.
