Abstract: Method and apparatus for reporting of time domain channel characteristics. The apparatus receives a Doppler configuration to measure Doppler information for at least one channel path of a plurality of channel paths. The apparatus receives a tracking reference signal (TRS) to obtain the Doppler information for the at least one channel path of the plurality of channel paths based on the Doppler configuration. The apparatus transmits a Doppler report comprising the Doppler information for the at least one channel path of the plurality of channel paths based on the received TRS. The apparatus receives a downlink transmission on a predicted channel and precoder, the predicted channel and the precoder based at least on the Doppler report.

Abstract: Certain aspects of the present disclosure provide techniques for configuring for communications on noncontiguous carriers of a single cell. By combining multiple noncontiguous carriers into a single cell, broadcast overhead can be reduced and cell management (i.e., only one cell) can be simplified. For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a second network node associated with a reconfigurable intelligent surface (RIS), positioning information associated with the RIS. The first network node may communicate, with a third network node, using a beam of a set of beams that is configured based at least in part on the positioning information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described technique provide for a user equipment (UE) to selectively transmit an uplink repetition configured with intra-slot frequency hopping during a slot including both sub-band full duplex (SBFD) and non-SBFD symbols. For example, the UE may receive a control message scheduling repetitions of an uplink message and indicating a configuration for intra-slot frequency hopping for the repetitions. In some cases, the UE may selectively transmit a repetition during a mixed symbol slot according to whether the slot is considered available, an alignment of a boundary between the SBFD symbols and non-SBFD symbols of the mixed symbol slot with time resources for portions of the repetition, transmission parameters associated with SBFD symbols and non-SBFD symbols, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first cell associated with a first uplink carrier and a first downlink carrier and a second cell associated with a second uplink carrier, wherein the second cell comprises an uplink-only cell. The UE may receive, via the first downlink carrier of the first cell or via the second downlink carrier associated with a third cell, a second indication of subsequent communications to be performed via the first uplink carrier of the first cell, the second uplink carrier of the second cell, or both. The UE may perform the subsequent communications according to the second indication, wherein the subsequent communications comprise at least one of access communications, uplink communications, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may transmit a first sidelink reference signal (SL-RS) to a second network node. The first network node may receive, from the second network node, a second SL-RS and channel state information (CSI) that is associated with the first (SL-RS). The first network node may determine a (CSI)-related parameter based on the second (SL-RS) and the (CSI). The first network node may transmit, to the second network node, the (CSI)-related parameter or a communication based on the (CSI)-related parameter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e.g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e.g., linear precoding (LP)) or a second type of precoding (e.g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.
