Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transport block (TB). The UE may fail to successfully decode the TB. The UE may transmit a negative acknowledgement (NACK) message based at least in part on the failing to successfully decode the TB. The NACK message may indicate a quantity of repetitions for retransmitting the TB. Numerous other aspects are described.

The apparatus may also signal configuration information of the frame structure including the plurality of slots. Additionally, the apparatus may communicate data via the frame structure including the plurality of slots.

Methods and apparatus for cross link interference mitigation

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.

Techniques for indicating sounding reference signal resources

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive, from a base station, a control message including an indication associated with a configuration for an interference measurement (IM) report in a channel state information (CSI) report. The UE may determine a setting of the configuration for the IM report based on the indication, which may include one or both of a resource setting associated with IM information in a frequency domain or a spatial setting associated with IM information in a spatial domain. The UE may generate the IM report based on one or both of the resource setting or the spatial setting and may transmit the CSI report including the IM report to the base station.

Differential mode for interference-specific channel state information report

Methods, systems, and devices for wireless communications are described. Described techniques provide for dynamic configuration of feedback, repetition, and/or modulation and coding scheme(s) for transmissions within an application data unit (ADU). A user equipment (UE) and a network entity may communicate control signaling indicating transmission configurations for a set of multiple time domain durations within an ADU and a start of a first time domain duration. The transmission configurations may indicate a number of repetitions for each transmission. In some cases, the network entity may transmit control signaling that separately configures a number of repetitions for each feedback process of a set of multiple feedback processes associated with an ADU and indicates whether repetition is enabled for each feedback process and a redundancy version identifier sequence for repetitions for each feedback process. The UE and the network entity may communicate transmissions within the ADU in accordance with the control signaling.

Adaptation for extended reality transmissions

Examples of the disclosure relate to generating a packet for transmission over a sidelink resource pool and transmitting the packet to a second UE on a set of sidelink resources of the sidelink resource pool. The set may be selected based on a resource selection procedure of a plurality of resource selection procedures. The resource selection procedure may be selected based at least in part on one or more utilization parameters corresponding to one or more resources of the sidelink resource pool. Other examples, and features are also claimed and described.

Resource allocation techniques for sidelink transmissions, and dynamic selection between resource allocation techniques based on sidelink communication reliability

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.

In some aspects, a network node may communicate, based at least in part on a physical data channel configuration corresponding to a physical data channel, a first extended reality (XR) data communication corresponding to a first physical data channel occasion associated with the physical data channel configuration, wherein a first priority level is associated with the first XR data communication. The network node may communicate a second XR data communication corresponding to a second physical data channel occasion, wherein a second priority level is associated with the second XR data communication, and wherein the second priority level is higher than the first priority level based at least in part on a packet delay budget associated with the physical data channel configuration being within a specified threshold of packet delay.
