Abstract: Certain aspects of the present disclosure provide techniques for compensating for certain characteristic(s) of an intelligent reflecting surface (IRS). A method that may be performed by a first wireless node includes obtaining an indication of a correction for an IRS to compensate for one or more characteristics of the IRS and communicating with a second wireless node via the IRS using the indication of the correction.

Abstract: Certain aspects of the present disclosure provide techniques for communicating with an ad hoc intelligent reflecting surface (IRS). A method that may be performed by a user equipment includes receiving signals from a network entity via an ad hoc IRS; configuring the IRS for communications between the UE and the network entity based at least in part on the received signals; and communicating with the network entity through the IRS.

Abstract: Methods, apparatuses, and computer-readable medium for fronthaul compression are provided. An example method may include receiving, from a UE, uplink data via one or more active tones of a plurality of tones in a symbol, the uplink data corresponding to an access vector. The example method may further include compressing the uplink data based on a linear transformation of a pseudo-access vector generated based on the access vector, the linear transformation including a matrix, the compression enabling a second network entity to decompress the compressed uplink data without knowing one or more locations associated with the one or more active tones. The example method may further include transmitting, to the second network entity, the compressed uplink data.

Abstract: A node may forward, from a base station to a first UE, or from the first UE to the base station, one or more wireless signals. The node may identify an indication to stop signal forwarding to the first UE. The indication may be based on a level of an interference to a second UE associated with the signal forwarding to the first UE being greater than a first threshold. The level of the interference to the second UE may be based on a path gain difference or a signal strength at the first UE associated with the signal forwarding to the first UE. The signal strength at the first UE associated with the signal forwarding to the first UE may correspond to an RSRP at the first UE. The node may stop the signal forwarding to the first UE based on the indication.

Abstract: A node may identify a node configuration including one or more surface phase configurations associated with the node. In one configuration, the node may receive, from the base station, an indication of the node configuration. In another configuration, the node may select, at a controller associated with the node, the node configuration. The one or more surface phase configurations may be based on a wavelength corresponding to a center of a BWP associated with the one or more wireless signals or a wavelength corresponding to a center of a resource allocation associated with the one or more wireless signals. The node may forward, from a base station to a UE, or from the UE to the base station, one or more wireless signals. The forwarded one or more wireless signals may be associated with a beam squint less than a first threshold.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity determines a set of position estimates associated with a set of user equipments (UEs), obtains first measurement information associated with a set of signals as reflected off of a target intelligent reflecting surface (IRS), determines a position estimate of the target IRS based on the set of position estimates and the first measurement information, and determines an orientation, relative to a common orientation reference frame, of the target IRS based on the set of position estimates and at least the first measurement information.

Abstract: An angular relationship determination method includes: obtaining, at an apparatus, a first phase difference indication corresponding to a first difference in phase between a first signal wirelessly received by a wireless signaling device from a transmitter and a second signal wirelessly received by the wireless signaling device from the transmitter; and determining, at the apparatus, a first angular relationship between the transmitter and the wireless signaling device based on the first phase difference indication, a first virtual focal point location corresponding to the first signal, and a second virtual focal point location corresponding to the second signal, the second virtual focal point location and the first virtual focal point location being different.

Abstract: A base station may identify one or more beams toward a node for communication with at least one UE. The one or more beams may correspond to a plurality of beams from the node. The base station may transmit, to the node, an indication to adjust a surface phase of the node corresponding to the one or more beams or one of the plurality of beams from the node. The base station may select at least one beam of the plurality of beams from the node for communication with the at least one UE. The base station may communicate with the at least one UE via the node and the at least one beam. The at least one beam of the plurality of beams from the node may be based on a defocusing operation associated with a virtual focal point.

Abstract: Methods and systems for operating a base station to reduce beam squinting include determining a lower bound on the number of directional beams used by the base station for millimeter wave wideband communications (e.g., based on operating conditions of the base station or wireless devices within the coverage area of the base station) and transmitting synchronization signal block (SSB) messages in an SSB Burst Set consistent with the determined lower bound on the number of directional beams used by the base station for millimeter wave wideband communications.
