    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for communicating an uplink grant and a channel state information reference signal (CSI-RS) trigger. A wireless device may identify e a pending collision for a slot of a carrier between a CSI-RS and uplink data. The wireless device may determine a communication configuration for the CSI-RS and the uplink data such that no collision occurs. The determined communication configuration for the CSI-RS may include delaying one of the colliding signals, transmitting only one of the colliding signals and suppressing the other, or reconfiguring the slot such that both signals can be transmitted successfully. Additionally, the UE and the base station may determine a CSI reporting configuration based on the determined communication configuration.

    Abstract: A signaling design for multiple aperiodic channel state information (M-A-CSI) feedback is disclosed. In new radio (NR) networks, there may be scenarios where M-A-CSI are triggered and reported simultaneously. Timing issues may arise because of the different delay periods for difference CSI processes and reporting. In a first aspect, a general set of delay times for the M-A-CSI maybe signaled to the user equipment (UE) from which a candidate set is selected by the UE based on various CSI related settings. An indication from the base station may then be used to select the delay from the candidate set. In a second aspect, a delay period may be selected from the set of delays associated with and corresponding to the M-A-CSI.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may perform, on a set of information bits, a distribution matching procedure to obtain a distributed amplitude symbol sequence. In some cases, the wireless device may perform the distribution matching procedure using approximations of quantities of distributed amplitude symbol sequences that each have a same length and a same transmission energy. The wireless device may then encode the distributed amplitude symbol sequence and transmit the encoded distributed amplitude sequence. A device that receives the encoded distributed amplitude sequence may perform a distribution dematching procedure on the distributed amplitude sequence based on approximating quantities of distributed amplitude symbol sequences.

    Abstract: Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration with a codebook list, for example, for non-coherent joint transmission (NCJT). A method for wireless communication that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource includes a set of ports or port groups. The UE receives a list of codebooks associated with the configuration. The UE determines at least one codebook, from the list of codebooks, to apply for one or more triggered CSI-RS resources.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support selection and quantization of time domain coefficients through an extended eType-II codebook. In a first aspect, a method of wireless communication includes measuring, by a user equipment (UE), a bundle of channel state information reference signals (CSI-RS) to determine channel quality information across a spatial domain, a frequency domain, and a time domain. The UE generates a first bitmap identifying a first plurality of non-zero coefficients (NZCs) selected to represent a first CSI for the spatial domain and the frequency domain, and a second bitmap identifying a second plurality of NZCs selected to represent a second CSI for the time domain. The UE would then transmit one or more CSI reports including one or both of the first bitmap and the second bitmap. Other aspects and features are also claimed and described.

    Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to determine channel state information (CSI) to feedback to a base station (BS) in a full-duplex wireless communications system while considering UE-to-UE interference and for the BS to configure the UE to provide the CSI to the BS. In an exemplary method, a UE receives, from a base station (BS) in a full-duplex communications system, a channel state information (CSI) report configuration including at least a first indicator of a first associated set of sounding reference signal (SRS) resources; and transmits to the BS a CSI report including CSI and zero or more second indicators of sets of measured SRS resources.
