Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: Apparatus, methods, and computer program products for repetition of XR information are provided. An example method may include receiving XR data associated with an XR application from a network entity. The example method may further include transmitting, for the network entity at a first time, a first transmission including a first instance of XR information and a second instance of XR information. The example method may further include transmitting, for the network entity at a second time, a second transmission including the second instance of XR information and a third instance of XR information, where a time difference between the first time and the second time may be based on a periodicity associated with the XR information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a first number of one or more transmit antennas supported by the UE for antenna switching and a second number of ports supported for uplink transmission that exceeds the first number of one or more transmit antennas. The UE may receive, based on the capability message, a sounding reference signal (SRS) configuration indicating a mapping between each SRS resource or SRS resource group and a respective bit sequence of a set of bit sequences. The UE may receive a control message comprising one or more bit sequences of the set of bit sequences indicating one or more SRS resources or an SRS resource group based on the mapping. The UE may transmit one or more SRS signals based on the control message.

Abstract: Certain aspects of the present disclosure provide techniques for file delivery feedback and/or application feedback for certain application services. An example method generally includes communicating files with a user equipment (UE), each of the files having a plurality of packets, determining that a delivery failure occurred for at least one of the files, and sending, to a server entity, a notification of the delivery failure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select one or more candidate sidelink resources, from within a resource selection window after sensing a sidelink channel, that are available for a second UE to use for transmission to the first UE. The UE may schedule, from among the candidate sidelink resources based at least in part on signal-to-interference ratios for the candidate sidelink resources, one or more scheduled sidelink resources that are preferred for transmission to the first UE. The UE may transmit, to the second UE, an indication of the candidate sidelink resources and the one or more scheduled sidelink resources. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, in a first broadcast message from a second UE, an indication of one or more sidelink resources in a resource selection window of a sidelink channel that are available for transmission by the second UE to a third UE. The UE may sense the sidelink channel. The UE may select one or more candidate sidelink resources that are available for a fourth UE to use for transmission to the first UE based at least in part on the indication in the broadcast message and the sensing of the sidelink channel. The UE may transmit, to the fourth UE in a second broadcast message, an indication of the candidate sidelink resources that are available for the fourth UE. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for sounding reference signal (SRS) guided downlink channel state information-reference signal (CSI-RS) scan. One example method for wireless communication generally includes determining whether to perform channel measurement and reporting operations for a user-equipment (UE) using a reciprocity-based scheme or a channel state information-reference signal (CSI-RS) based scheme based on a criteria of a cell, and performing the channel measurement and reporting operations based on the determination

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for a first cell, wherein the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. A first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a signaling communication that includes information specifying whether a channel state information reference signal (CSI-RS) precoding resource block group includes a same quantity of resource blocks (RBs) that is included in a CSI reporting subband configured for the UE. The CSI-RS precoding resource block group may enable the UE to perform a channel estimation based at least in part on a CSI-RS transmitted by a base station. The UE may perform the channel estimation based at least in part on the CSI-RS transmitted by the base station. The channel estimation may be based at least in part on whether the CSI-RS precoding resource block group includes the same quantity of RBs that is included in the CSI reporting subband configured for the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.
