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 one or more candidate two-dimensional hypotheses for channel state information (CSI) reporting. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more preferred two-dimensional hypotheses, from the candidate two-dimensional hypotheses. The UE may further determine one or more downlink transmission parameters for a downlink the UE receives, corresponding to the preferred two-dimensional hypotheses. The UE then transmits a CSI report that includes an indication of preferred two-dimensional hypotheses. The CSI report may further include the determined downlink transmission parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing for fine granularity CSI. A method for wireless communications by a user equipment (UE) includes receiving a CSI reporting configuration. The CSI reporting configuration includes a number of frequency domain (FD) units and a FD unit size for CSI reporting. The UE determines a number of CSI processing units at the UE to use for processing the CSI report based on the number of FD units or the FD unit size for the CSI report. The UE processes the CSI report based on the determined number CSI processing units. In another method, the UE determines at least one threshold to use for determining whether to update a CSI report based on the number of FD units or the FD unit size for CSI reporting.

Abstract: Aspects of the present disclosure provide techniques for transmitting an uplink preemption indication in an integrated access and backhaul (IAB) system identifying the resources or symbols that may be punctured by the IAB in order to minimize self-interference at an IAB node when an ultra-reliable-low latency communications (URLLC) packet is received at the IAB node from one of a child IAB node or a user equipment (UE) during an on-going uplink transmission from an IAB node to a parent backhaul node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may identify a collision between a data transmission and a demodulation reference signal (DMRS) transmission in a full-duplex time-frequency resource. The BS may transmit, to a wireless communication device, an indication of a time-frequency mapping for a zero-power DMRS (ZP-DMRS) in the full-duplex time-frequency resource. The time-frequency mapping for the ZP-DMRS, and a time-frequency mapping in the full-duplex time-frequency resource for the DMRS transmission, may be a same time-frequency mapping. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.

Abstract: Aspects of the disclosure relate to the generation of channel state reports and precoding a wireless transmission based on frequency division duplex (FDD) reciprocity. A base station (B S) uses at least two precoders to transmit signals to A user equipment (UE). The UE generates a set of channel state reports, in which the UE transmits a first set of channel coefficients using a first timing, a set of port attributes using a second timing, and a second set of channel coefficients using a third timing. The first set of channel coefficients correspond to a first precoded portion of the wireless transmission, and the set of port attributes and the second set of channel coefficients correspond to a second portion of the wireless transmission. The BS modifies at least one of the precoders based on the channel state reports. Other aspects, embodiments, and features are also claimed and described.
