Abstract: Methods, systems, and devices for wireless communication are described that provide for the utilization of multiple partial bands used in the transmission of one or more channel state information (CSI) reference signals (CSI-RSs). The partial bands may be non-consecutive in the frequency domain, time domain, or a combination thereof and each of which may be precoder using a different precoder configuration. The time intervals, cycling granularity, and number of ports may vary between partial bands. Using RSs transmitted via the multiple partial bands, a user equipment (UE) may determine a channel state parameter for each partial band, which may be used for channel feedback.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration that may identify a set of time and frequency resources for transmission of sounding reference signals, the set of time and frequency resources including a plurality of subsets of time and frequency resources. Each subset of time and frequency resources of the plurality of subsets of time and frequency resources may be associated with a corresponding value of a plurality of values of a partial frequency parameter. The UE may receive control signaling indicating a value of the partial frequency parameter of the plurality of values. The UE may transmit a sounding reference signal on a subset of time and frequency resources of the plurality of subsets of time and frequency resources that corresponds to the value of the partial frequency parameter indicated by the received control signaling.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) configured to receive a downlink in a network configured for full duplex communication. The UE receives from the network an indication of a maximum rank of an uplink from an interfering, aggressor UE. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more rank values for the aggressor UE, less than or equal to the maximum rank. The UE may further determine one or more channel parameters for downlink transmissions the UE receives, corresponding to the determined rank values. The UE then transmits a channel state information (CSI) report that includes an indication of at least one of the one or more rank values for the aggressor UE. The CSI report may further include the determined channel parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: An improved transmission configuration indicator (TCI) state for channel state information (CSI) reporting is disclosed for full-duplex systems. In such systems, a potentially victim user equipment (UE) may receive a CSI report configuration message including at least a TCI state and a quasi-colocation (QCL) type indicator. The TCI state includes identification of at least a downlink reference signal resource and an uplink reference signal resource, while the QCL type indicator indicates a spatial relationship between the downlink and uplink reference signals. The UE may then determine a receive beam for receipt of a downlink reference signal, wherein the receive beam is determined based on the QCL type indicator. The UE generates and transmits a CSI report based on the receipt of the downlink reference signal using the determined receive beam and an interference measurement of the uplink reference signal resource.

Abstract: Certain aspects of the present disclosure provide techniques for collision handling for channel state information (CSI) reporting on a physical uplink shared channel (PUSCH). A method for wireless communications by a user equipment (UE) is provided. The method generally includes receiving scheduling for at least one CSI reporting transmission and at least one uplink transmission in a same slot. The UE determines to multiplex the at least one CSI and the at least one uplink transmission in the slot or to drop the at least one CSI or the at least one uplink transmission in the slot. The UE transmits in the slot at least one of: the at least one CSI transmission or the at least one uplink transmission based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may allocate data associated with a user equipment (UE), of two or more UEs, into at least one of a first part, a second part, or a combination thereof; multiplex the first part of the data associated with the UE with a first part of data associated with one or more other UEs, of the two or more UEs, to form multiplexed data; map the multiplexed data to a first set of layers; and map the second part of the data associated with the UE and a second part of the data associated with the one or more other UEs to a second set of layers. Numerous other aspects are provided.

Abstract: The described techniques provide for the use of sub-band-specific reference signal precoding. A user equipment (UE) may apply multiple precoding matrices to a reference signal to generate a set of precoded reference signals and may transmit the precoded reference signals over respective sub-bands within a given reference signal resource set. In some cases, the UE may transmit a different set of precoded reference signals in each of multiple reference signal resource sets. Upon receiving the precoded reference signals, a base station may perform wideband channel estimation for each sub-band in the given reference signal resource set. The base station may compute an average spectral efficiency for each reference signal resource set and may transmit a report to the UE. The report may include one or more communication parameters for future communications between the UE and base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration associated with a layer to reference signal port mapping. In some cases, the UE may identify, based at least in part on the configuration, that at least one layer of a set of layers for receiving a downlink transmission from the base station is adapted based on at least one interference layer. In some cases, the adapted layer may be mapped to one or more reference signal ports. The UE may receive the downlink transmission and may decode the downlink transmission based on identifying that the at least one layer is adapted and the layer to reference signal port mapping.
