Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may decode a downlink communication on a physical downlink shared channel (PDSCH). The downlink communication may have punctured resources. The UE may transmit, in association with the downlink communication, a first uplink communication on a physical uplink shared channel (PUSCH), and measure self-interference in the punctured resources of the downlink communication on the PDSCH that are within a threshold distance of resources of the first uplink communication on the PUSCH. Numerous other aspects are provided.

Abstract: Some examples of the techniques described herein may provide approaches for scheduling a sounding reference signal (SRS) in a time-division duplex (TDD) structure with one or more mixed sub-band full-duplex (SBFD) slots. For SRS based on physical slot counting, for example, some of the techniques described herein may provide approaches indicating whether to transmit or drop SRS resources in SBFD or non-SBFD symbols in a mixed SBFD slot. For SRS based on available slot counting, for example, some of the techniques described herein may indicate whether a mixed SBFD slot is an available slot for SRS transmission. For duplex-specific SRS, for example, some of the techniques described herein may indicate whether to label or determine a mixed SBFD slot as an SBFD-specific slot or non-SBFD-specific slot, or whether a resource in a mixed SBFD slot may be sent or dropped.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message, from a network entity, indicating assistance information including a decoding order, decoder iteration instructions, or both, for a first set of repetitions of a data transmission. The UE may monitor for and receive the first set of repetitions from the network entity and decode the first set of repetitions based on the assistance information from the network entity. Based on decoding the first set of repetitions, the UE may transmit a feedback message to the network entity indicating whether the UE successfully decoded the first set of repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a plurality of port arrangements for transmitting one or more sounding reference signals to the base station. The UE may select a port arrangement of the plurality of port arrangements based on a first quantity of ports available to the UE for transmitting the one or more sounding reference signals. The UE may transmit a first sounding reference signal using a second quantity of ports of the first quantity of ports based on the selected port arrangement. Further, the UE may transmit a second sounding reference signal using a third quantity of ports of the first quantity of ports based on the selected port arrangement.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sounding reference signal (SRS) management for a line-of-sight multiple-input multiple-output (LSM) mode. A receiving device may receive a configuration of a persistent or semi-persistent SRS resource set that configures a first number of SRS ports for a full spatial sounding mode. The receiving device may transmit a SRS on a partial sounding resource subset of the SRS resource set, the partial sounding resource subset corresponding to a partial sounding LSM mode. A transmitting device such as a base station may performing phase ramp interpolation for the partial sounding LSM mode to estimate a LSM channel between the base station and the first receiving device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of resource parameters for performing sounding reference signal transmissions during a slot comprising at least one subband full-duplex symbol and at least one non-subband full-duplex symbol. The UE may perform multi-symbol sounding reference signal transmissions during the slot according to a transmission scheme associated with the resource parameters, the transmission scheme defining a transmit or drop rule based on a first subset of sounding reference signal transmissions being scheduled in the at least one subband full-duplex symbol of the slot and a second subset of sounding reference signal transmissions being scheduled in the at least one non-subband full-duplex symbol of the slot.

Abstract: Certain aspects of the present disclosure provide techniques for full duplex (FD) operation under cell discontinuous transmission (DTX) and discontinuous reception (DRX). An example method, performed at a user equipment (UE), includes receiving configuration information indicating, for a network entity operating in a subband full duplex (SBFD) mode, DRX cycles and DTX cycles, wherein each DRX cycle has an inactive DRX period and an active DRX period and each DTX cycle has an inactive DTX period and an active DTX period, determining that an SBFD slot occurs during an overlap of 1) an active DRX period and an inactive DTX period or 2) an inactive DRX period and an active DTX period, and performing one or more actions during the SBFD slot, based on the determination and whether the UE is configured to communicate on an uplink subband or a downlink subband in the SBFD slot.
