Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sounding reference signal (SRS) management for a line-of-sight multiple-input multiple-output (LSM) mode. A receiving device may receive a configuration of a persistent or semi-persistent SRS resource set that configures a first number of SRS ports for a full spatial sounding mode. The receiving device may transmit a SRS on a partial sounding resource subset of the SRS resource set, the partial sounding resource subset corresponding to a partial sounding LSM mode. A transmitting device such as a base station may performing phase ramp interpolation for the partial sounding LSM mode to estimate a LSM channel between the base station and the first receiving device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a grant for a communication with the base station. The UE may determine whether the communication is associated with a hybrid automatic repeat request (HARQ)-based transmission mode or a HARQ-less transmission mode. The UE may communicate with the base station based at least in part on the grant and the determination of whether the communication is associated with the HARQ-based transmission mode or the HARQ-less transmission mode.

Abstract: Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink subchannels.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a configuration for identifying availability and reliability of the availability for resources of a sidelink resource pool based on a plurality of signal quality thresholds. The UE may indicate, for each resource of a set of resources of the sidelink resource pool and based on the configuration, an indication of availability with respect to a first signal quality threshold and an indication of reliability of the availability with respect to a second signal quality threshold. The UE may select one or more resources of the sidelink resource pool based on the indication of availability and the indication of reliability of the availability for each resource of the set of resources.

Abstract: Schemes and mechanisms for timing advance adjustment are provided. In a method for wireless communication, a BS transmits, to a user equipment (UE), a first timing offset configuration associated with a first reconfigurable intelligent surface (RIS) state and a second timing offset configuration associated with a second RIS state. The BS transmits, to the UE, a timing offset indication indicating one of the first timing offset configuration or the second timing offset configuration. The BS receives, from the UE based on the timing offset indication, an uplink (UL) communication.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may determine to change a power mode of the UE to a new power mode. The UE may change the power mode of the UE to the new power mode, wherein if the new power mode comprises a power saving mode, the UE measures positioning reference signals (PRSs) from one transmission/reception point (TRP), and wherein if the new power mode is a normal power mode, the UE measures PRSs from two or more TRPs.

Abstract: Aspects of the disclosure relate to a reconfigurable intelligent surface (RIS) controller for controlling a RIS panel to be frequency and/or element dependent, and for operating an adaptive filtering function. The RIS controller may be configured to transmit, to a scheduling entity, a RIS frequency capability indication for indicating communication support of the RIS panel for one or more frequency ranges. The scheduling entity, then, may transmit RIS control information based on the RIS frequency capability indication. In response, the RIS controller may receive the RIS control information and configure the RIS panel based on the RIS control information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a reconfigurable intelligent surface (RIS) may transmit a capability information message including an indicating that the RIS is capable of participating in network communications and communicating with other RISs on the network. A first RIS may communicate beam information to a second RIS directly, or the first RIS may communicate beam information to the second RIS via a base station, or the first RIS may communicate beam information to the second RIS via a user equipment (UE). In some examples, one RIS may request beam information or reflecting assistance from another RIS.
